6000 PRODUCT 6200 INFORMATION PROGLYCEM® brand of diazoxide Capsules Suspension, USP FOR ORAL ADMINISTRATION Rx Only DESCRIPTION PROGLYCEM® (diazoxide) is a nondiuretic benzothiadiazine derivative taken orally for the management of symptomatic hypoglycemia. PROGLYCEM® Capsules contain 50 mg diazoxide, USP. The Suspension contains 50 mg of diazoxide, USP in each milliliter and has a chocolate- mint flavor; alcohol content is approximately 7.25%. Other ingredients: Sorbitol solution, chocolate cream flavor, propylene glycol, magnesium aluminum silicate, carboxymethycellulose sodium, mint flavor, sodium benzoate, methylparaben, poloxamer 188, propylparaben, and purified water. Hydrochloric acid or sodium hydroxide may be added to adjust pH. Diazoxide has the following structural formula: Diazoxide is 7-chloro-3-methyl-2H-1,2,4-benzothiadiazine 1,1-dioxide with the empirical formula C8H7CIN2O2S and the molecular weight 230.7. It is a white powder practically insoluble to sparingly soluble in water. CLINICAL PHARMACOLOGY Diazoxide administered orally produces a prompt dose-related increase in blood glucose level, due primarily to an inhibition of insulin release from the pancreas, and also to an extrapancreatic effect. The hyperglycemic effect begins within an hour and generally lasts no more than eight hours in the presence of normal renal function. PROGLYCEM® decreases the excretion of sodium and water, resulting in fluid retention which may be clinically significant. The hypotensive effect of diazoxide on blood pressure is usually not marked with the oral preparation. This contrasts with the intravenous preparation of diazoxide (see ADVERSE REACTIONS). Other pharmacologic actions of PROGLYCEM® include increased pulse rate; increased serum uric acid levels due to decreased excretion; increased serum levels of free fatty acids’ decreased chloride excretion; decreased para-aminohippuric acid; (PAH) clearance with no appreciable effect on glomerular filtration rate. 1 Reference ID: 3822049 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda The concomitant administration of a benzothiazide diuretic may intensify the hyperglycemic and hyperuricemic effects of PROGLYCEM®. In the presence of hypokalemia, hyperglycemic effects are also potentiated. PROGLYCEM®-induced hyperglycemia is reversed by the administration of insulin or tolbutamide. The inhibition of insulin release by PROGLYCEM® is antagonized by alpha­ adrenergic blocking agents. PROGLYCEM® is extensively bound (more than 90%) to serum proteins, and is excreted in the kidneys. The plasma half-life following I.V. administration is 28 ± 8.3 hours. Limited data on oral administration revealed a half-life of 24 and 36 hours in two adults. In four children aged four months to six years, the plasma half-life varied from 9.5 to 24 hours on long-term oral administration. The half-life may be prolonged following overdosage, and in patients with impaired renal function. INDICATIONS AND USAGE PROGLYCEM® (ORAL DIAZOXIDE) is useful in the management of hypoglycemia due to hyperinsulinism associated with the following conditions: Adults: Inoperable islet cell adenoma or carcinoma, or extrapancreatic malignancy. Infants and Children: Leucine sensitivity, islet cell hyperplasia, nesidioblastosis, extrapancreatic malignancy, islet cell adenoma, or adenomatosis. PROGLYCEM® may be used preoperatively as a temporary measure, and postoperatively, if hypoglycemia persists. PROGLYCEM® should be used only after a diagnosis of hypoglycemia due to one of the above conditions has been definitely established. When other specific medical therapy or surgical management either has been unsuccessful or is not feasible, treatment with PROGLYCEM® should be considered. CONTRAINDICATIONS The use of PROGLYCEM® for functional hypoglycemia is contraindicated. The drug should not be used in patients hypersensitive to diazoxide or to other thiazides unless the potential benefits outweigh the possible risks. WARNINGS The antidiuretic property of diazoxide may lead to significant fluid retention, which in patients with compromised cardiac reserve, may precipitate congestive heart failure. The fluid retention will respond to conventional therapy with diuretics. It should be noted that concomitantly administered thiazides may potentiate the hyperglycemic and hyperuricemic actions of diazoxide (See DRUG INTERACTIONS and ANIMAL PHARMACOLOGY AND/OR TOXICOLOGY). Ketoacidosis and nonketotic hyperosmolar coma have been reported in patients treated with recommended doses of PROGLYCEM® usually during intercurrent illness. Prompt recognition and treatment are essential (See OVERDOSAGE), and prolonged surveillance following the acute episode is necessary because of the long drug half-life of approximately 30 hours. The occurrence of these serious events may be reduced by careful education of patients regarding the need for monitoring the urine for sugar and ketones and for prompt reporting of abnormal 2 Reference ID: 3822049 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda findings and unusual symptoms to the physician. Transient cataracts occurred in association with hyperosmolar coma in an infant, and subsided on correction of the hyper-osmolarity. Cataracts have been observed in several animals receiving daily doses of intravenous or oral diazoxide. The development of abnormal facial features in four children treated chronically (>4 years) with PROGLYCEM® for hypoglycemia hyperinsulinism in the same clinic has been reported. Pulmonary Hypertension in Neonates and Infants There have been postmarketing reports of pulmonary hypertension occurring in infants and neonates treated with diazoxide. The cases were reversible upon discontinuation of the drug. Monitor patients, especially those with risk factors for pulmonary hypertension, for respiratory distress and discontinue diazoxide if pulmonary hypertension is suspected. PRECAUTIONS General: Treatment with PROGLYCEM® should be initiated under close clinical supervision, with careful monitoring of blood glucose and clinical response until the patient’s condition has stabilized. This usually requires several days. If not effective in two to three weeks, the drug should be discontinued. Prolonged treatment requires regular monitoring of the urine for sugar and ketones, especially under stress conditions, with prompt reporting of any abnormalities to the physician. Additionally, blood sugar levels should be monitored periodically by the physician to determine the need for dose adjustment. The effects of diazoxide on the hematopoietic system and the level of serum uric acid should be kept in mind; the latter should be considered particularly in patients with hyperuricemia or a history of gout. In some patients, higher blood levels have been observed with the oral suspension than with the capsule formulation of PROGLYCEM®. Dosage should be adjusted as necessary in individual patients if changed from one formulation to the other. Since the plasma half-life of diazoxide is prolonged in patients with impaired renal function, a reduced dosage should be considered. Serum electrolyte levels should also be evaluated for such patients. The antihypertensive effect of other drugs may be enhanced by PROGLYCEM®, and this should be kept in mind when administering it concomitantly with antihypertensive agents. Because of the protein binding, administration of PROGLYCEM® with coumarin or its derivatives may require reduction in the dosage of the anticoagulant, although there has been no reported evidence of excessive anticoagulant effect. In addition, PROGLYCEM® may possibly displace bilirubin from albumin; this should be kept in mind particularly when treating newborns with increased bilirubinemia. Pulmonary hypertension has been reported in neonates and young infants treated with diazoxide. (see WARNINGS) Information for Patients: 3 Reference ID: 3822049 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda During treatment with PROGLYCEM® the patient should be advised to consult regularly with the physician and to cooperate in the periodic monitoring of his condition by laboratory tests. In addition, the patient should be advised: • to take the drug on a regular schedule as prescribed, not to skip doses, not to take extra doses; • not to use this drug with other medications unless this is done with the physician’s advice; • not to allow anyone else to take this medication; • to follow dietary instructions; • to report promptly any adverse effects (i.e., increased urinary frequency, increased thirst, fruity breath odor); • to report pregnancy or to discuss plans for pregnancy. Laboratory tests: The following procedures may be especially important in patient monitoring (not necessarily inclusive); blood glucose determinations (recommended at periodic intervals in patients taking diazoxide orally for treatment of hypoglycemia, until stabilized); blood urea nitrogen (BUN) determinations and creatinine clearance determinations; hematocrit determinations; platelet count determinations; total and differential leukocyte counts; serum aspartate aminotransferase (AST) level determinations; serum uric acid level determinations; and urine testing for glucose and ketones (in patients being treated with diazoxide for hypoglycemia, semiquantitative estimation of sugar and ketones in serum performed by the patient and reported to the physician provides frequent and relatively inexpensive monitoring of the condition). Drug Interactions: Since diazoxide is highly bound to serum proteins, it may displace other substances which are also bound to protein, such as bilirubin or coumarin and its derivatives, resulting in higher blood levels of these substances. Concomitant administration of oral diazoxide and diphenylhydantoin may result in a loss of seizure control. These potential interactions must be considered when administering PROGLYCEM® Capsules or Suspension. The concomitant administration of thiazides or other commonly used diuretics may potentiate the hyperglycemic and hyperuricemic effects of diazoxide. Drug/Laboratory Test Interactions: The hyperglycemic and hyperuricemic effects of diazoxide preclude proper assessment of these metabolic states. Increased renin secretion, IgG concentrations and decreased cortisol secretions have also been noted. Diazoxide inhibits glucagon-stimulated insulin release and causes a false- negative insulin response to glucagon. Carcinogenesis, mutagenesis, impairment of fertility: No long-term animal dosing study has been done to evaluate the carcinogenic potential of diazoxide. No laboratory study of mutagenic potential or animal study of effects on fertility has been done. 4 Reference ID: 3822049 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda Pregnancy Category C: Reproduction studies using the oral preparation in rats have revealed increased fetal resorptions and delayed parturition, as well as fetal skeletal anomalies; evidence of skeletal and cardiac teratogenic effects in rabbits has been noted with intravenous administration. The drug has also been demonstrated to cross the placental barrier in animals and to cause degeneration of the fetal pancreatic beta cells (See ANIMAL PHARMACOLOGY AND/OR TOXICOLOGY). Since there are no adequate data on fetal effects of this drug when given to pregnant women, safety in pregnancy has not been established. When the use of PROGLYCEM® is considered, the indications should be limited to those specified above for adults (See INDICATIONS AND USAGE), and the potential benefits to the mother must be weighed against possible harmful effects to the fetus. Non-teratogenic effects: Diazoxide crosses the placental barrier and appears in cord blood. When given to the mother prior to delivery of the infant, the drug may produce fetal or neonatal hyperbilirubinemia, thrombocytopenia, altered carbohydrate metabolism, and possibly other side effects that have occurred in adults. Alopecia and hypertrichosis lanuginosa have occurred in infants whose mothers received oral diazoxide during the last 19 to 60 days of pregnancy. Labor and delivery: Since intravenous administration of the drug during labor may cause cessation of uterine contractions, and administration of oxytocic agents may be required to reinstate labor, caution is advised in administering PROGLYCEM® at that time. Nursing mothers: Information is not available concerning the passage of diazoxide in breast milk. Because many drugs are excreted in human milk and because of the potential for adverse reactions from diazoxide in nursing infants, a decision should be made whether to discontinue nursing or to discontinue the drug, taking into account the importance of the drug to the mother. Pediatric use: (See INDICATIONS AND USAGE). ADVERSE REACTIONS: Frequent and Serious: Sodium and fluid retention is most common in young infants and in adults and may precipitate congestive heart failure in patients with compromised cardiac reserve. It usually responds to diuretic therapy (See DRUG INTERACTIONS). Infrequent but Serious: Diabetic ketoacidosis and hyperosmolar nonketotic coma may develop very rapidly. Conventional therapy with insulin and restoration of fluid and electrolyte balance is usually effective if instituted promptly. Prolonged surveillance is essential in view of the long half-life of PROGLYCEM® (See OVERDOSAGE). 5 Reference ID: 3822049 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda Other frequent adverse reactions: Hirsutism of the lanugo type, mainly on the forehead, back and limbs, occurs most commonly in children and women and may be cosmetically unacceptable. It subsides on discontinuation of the drug. Hyperglycemia or glycosuria may require reduction in dosage in order to avoid progression to ketoacidosis or hyperosmolar coma. Gastrointestinal intolerance may include anorexia, nausea, vomiting, abdominal pain, ileus, diarrhea, transient loss of taste. Tachycardia, palpitations, increased levels of serum uric acid are common. Thrombocytopenia with or without purpura may require discontinuation of the drug. Neutropenia is transient, is not associated with increased susceptibility to infection, and ordinarily does not require discontinuation of the drug. Skin rash, headache, weakness, and malaise may also occur. Other adverse reactions which have been observed are: Cardiovascular: hypotension occurs occasionally, which may be augmented by thiazide diuretics given concurrently. A few cases of transient hypertension, for which no explanation is apparent, have been noted. Chest pain has been reported rarely. Pulmonary hypertension has been reported in neonates and young infants (see WARNINGS). Hematologic: eosinophilia; decreased hemoglobin / hematocrit; excessive bleeding, decreased IgG. Hepato-renal: increased AST, alkaline phosphatase; azotemia, decreased creatinine clearance, reversible nephrotic syndrome, decreased urinary output, hematuria, albuminuria. Neurologic: anxiety, dizziness, insomnia, polyneuritis, paresthesia, pruritus, extrapyramidal signs. Ophthalmologic: transient cataracts, subconjunctival hemorrhage, ring scotoma, blurred vision, diplopia, lacrimation. Skeletal, integumentary; monilial dermatitis, herpes, advance in bone age; loss of scalp hair. Systemic: fever, lymphadenopathy. Other; gout acute pancreatitis/pancreatic necrosis, galactorrhea, enlargement of lump in breast. OVERDOSAGE An overdosage of PROGLYCEM® causes marked hyperglycemia which may be associated with ketoacidosis. It will respond to prompt insulin administration and restoration of fluid and electrolyte balance. Because of the drug’s long half-life (approximately 30 hours), the symptoms of overdosage require prolonged surveillance for periods up to seven days until the blood sugar level stabilizes within the normal range. One investigator reported successful lowering of diazoxide blood levels by peritoneal dialysis in one patient and by hemodialysis in another. DOSAGE AND ADMINISTRATION Patients should be under close clinical observation when treatment with PROGLYCEM® is initiated. The clinical response and blood glucose level should be carefully monitored until the patient’s condition has stabilized satisfactory; in most instances, this may be accomplished in several days. If administration of PROGLYCEM® is not effective after two or three weeks, the drug should be discontinued. 6 Reference ID: 3822049 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda The dosage of PROGLYCEM® must be individualized based on the severity of the hypoglycemic condition and the blood glucose level and clinical response of the patient. The dosage should be adjusted until the desired clinical and laboratory effects are produced with the least amount of the drug. Special care should be taken to assure accuracy of dosage in infants and young children. Adults and children: The usual daily dosage is 3 to 8 mg/kg, divided into two or three equal doses every 8 or 12 hours. In certain instances, patients with refractory hypoglycemia may require higher dosages. Ordinarily, an appropriate starting dosage is 3 mg/kg/day, divided into three equal doses every 8 hours. Thus an average adult would receive a starting dosage of approximately 200 mg daily. Infants and newborns: The usual daily dosage is 8 to 15 mg/kg divided into two or three equal doses every 8 to 12 hours. An appropriate starting dosage is 10 mg/kg/day, divided into three equal doses every 8 hours. ANIMAL PHARMACOLOGY AND/OR TOXICOLOGY Oral diazoxide in the mouse, rat, rabbit, dog, pig, and monkey produces a rapid and transient rise in blood glucose levels. In dogs, increased blood glucose is accompanied by increased free fatty acids, lactate, and pyruvate in the serum. In mice, a marked decrease in liver glycogen and an increase in the blood urea nitrogen level occur. In acute toxicity studies the LD50 for oral diazoxide suspension is >5000 mg/kg in the rat, >522 mg/kg in the neonatal rat, between 1900 and 2572 mg/kg in the mouse, and 219 mg/kg in the guinea pig. Although the oral LD50 was not determined in the dog, a dosage of up to 500 mg/kg was well tolerated. In subacute oral toxicity studies, diazoxide at 400 mg/kg in the rat produced growth retardation, edema, increases in liver and kidney weights, and adrenal hypertrophy. Daily dosages up to 1080 mg/kg for three months produced hyperglycemia, an increase in liver weight and an increase in mortality. In dogs given oral diazoxide at approximately 40 mg/kg/day for one month, no biologically significant gross or microscopic abnormalities were observed. Cataracts, attributed to markedly disturbed carbohydrate metabolism, have been observed in a few dogs given repeated daily doses of oral or intravenous diazoxide. The lenticular changes resembled those which occur experimentally in animals with increased blood glucose levels. In chronic toxicity studies, rats given a daily dose of 200 mg/kg diazoxide for 52 weeks had a decrease in weight gain and an increase in heart, liver, adrenal and thyroid weights. Mortality in drug-treated and control groups was not different. Dogs treated with diazoxide at dosages of 50, l00, and 200 mg/kg/day for 82 weeks had higher blood glucose levels than controls. Mild bone marrow stimulation and increased pancreas weights were evident in the drug-treated dogs; several developed inguinal hernias, one had a testicular seminoma, and another had a mass near the penis. Two females had inguinal mammary swellings. The etiology of these changes was not established. There was no difference in mortality between drug-treated and control groups. In a second chronic oral toxicity study, dogs given milled diazoxide at 50, l00, and 200 mg/kg/day had anorexia and sever weight loss, causing death in a few. Hematologic, biochemical, and 7 Reference ID: 3822049 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda histologic examination did not indicate any cause of death other than inanition. After one year of treatment, there is no evidence of herniation or tissue swelling in any of the dogs. When diazoxide was administered at high dosages concomitantly with either chlorothiazide to rats or trichlormethiazide to dogs, increased toxicity was observed. In rats, the combination was nephrotoxic; epithelial hyperplasia was observed in the collecting tubules. In dogs, a diabetic syndrome was produced which resulted in ketosis and death. Neither of the drugs given alone produced these effects. Although the data are inconclusive, reproduction and teratology studies in several species of animals indicate that diazoxide, when administered during the critical period of embryo formation, may interfere with normal fetal development, possibly through altered glucose metabolism. Parturition was occasionally prolonged in animals treated at term. Intravenous administration of diazoxide to pregnant sheep, goats, and swine produced in the fetus an appreciable increase in blood glucose level and degeneration of the beta cells of the Islets of Langerhans. The reversibility of these effects was not studied.

---------- NDA 17407/S-036 Page 4 CATAPRES - clonidine hydrochloride tablet Boehringer Ingelheim Pharmaceuticals Inc. Catapres (clonidine hydrochloride, USP) Oral Antihypertensive Tablets of 0.1, 0.2 and 0.3 mg Prescribing Information DESCRIPTION Catapres (clonidine hydrochloride, USP) is a centrally acting alpha-agonist hypotensive agent available as tablets for oral administration in three dosage strengths: 0.1 mg, 0.2 mg and 0.3 mg. The 0.1 mg tablet is equivalent to 0.087 mg of the free base. The inactive ingredients are colloidal silicon dioxide, corn starch, dibasic calcium phosphate, FD&C Yellow No. 6, gelatin, glycerin, lactose, and magnesium stearate. The Catapres 0.1 mg tablet also contains FD&C Blue No.1 and FD&C Red No.3. Clonidine hydrochloride is an imidazoline derivative and exists as a mesomeric compound. The chemical name is 2-(2,6-dichlorophenylamino)-2-imidazoline hydrochloride. The following is the structural formula: Structural Formula Clonidine hydrochloride is an odorless, bitter, white, crystalline substance soluble in water and alcohol. CLINICAL PHARMACOLOGY Clonidine stimulates alpha-adrenoreceptors in the brain stem. This action results in reduced sympathetic outflow from the central nervous system and in decreases in peripheral resistance, renal vascular resistance, heart rate, and blood pressure. Catapres tablets act relatively rapidly. The patient’s blood pressure declines within 30 to 60 minutes after an oral dose, the maximum decrease occurring within 2 to 4 hours. Renal blood flow and glomerular filtration rate remain essentially unchanged. Normal postural reflexes are intact; therefore, orthostatic symptoms are mild and infrequent. This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda NDA 17407/S-036 Page 5 Acute studies with clonidine hydrochloride in humans have demonstrated a moderate reduction (15% to 20%) of cardiac output in the supine position with no change in the peripheral resistance: at a 45° tilt there is a smaller reduction in cardiac output and a decrease of peripheral resistance. During long term therapy, cardiac output tends to return to control values, while peripheral resistance remains decreased. Slowing of the pulse rate has been observed in most patients given clonidine, but the drug does not alter normal hemodynamic response to exercise. Tolerance to the antihypertensive effect may develop in some patients, necessitating a reevaluation of therapy. Other studies in patients have provided evidence of a reduction in plasma renin activity and in the excretion of aldosterone and catecholamines. The exact relationship of these pharmacologic actions to the antihypertensive effect of clonidine has not been fully elucidated. Clonidine acutely stimulates growth hormone release in both children and adults, but does not produce a chronic elevation of growth hormone with long-term use. Pharmacokinetics The plasma level of clonidine peaks in approximately 3 to 5 hours and the plasma half-life ranges from 12 to 16 hours. The half-life increases up to 41 hours in patients with severe impairment of renal function. Following oral administration about 40-60% of the absorbed dose is recovered in the urine as unchanged drug in 24 hours. About 50% of the absorbed dose is metabolized in the liver. Neither food nor the race of the patient influences the pharmacokinetics of clonidine. INDICATIONS AND USAGE Catapres (clonidine hydrochloride, USP) tablets are indicated in the treatment of hypertension. Catapres tablets may be employed alone or concomitantly with other antihypertensive agents. CONTRAINDICATIONS Catapres tablets should not be used in patients with known hypersensitivity to clonidine (see PRECAUTIONS). WARNINGS Withdrawal Patients should be instructed not to discontinue therapy without consulting their physician. Sudden cessation of clonidine treatment has, in some cases, resulted in symptoms such as nervousness, agitation, headache, and tremor accompanied or followed by a rapid rise in blood pressure and elevated catecholamine concentrations in the plasma. The likelihood of such reactions to discontinuation of clonidine therapy appears to be greater after administration of higher doses or continuation of concomitant beta-blocker treatment and special caution is therefore advised in these situations. Rare instances of hypertensive encephalopathy, cerebrovascular accidents and death have been reported after clonidine withdrawal. When This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda NDA 17407/S-036 Page 6 discontinuing therapy with Catapres (clonidine hydrochloride, USP) tablets, the physician should reduce the dose gradually over 2 to 4 days to avoid withdrawal symptomatology. An excessive rise in blood pressure following discontinuation of Catapres tablets therapy can be reversed by administration of oral clonidine hydrochloride or by intravenous phentolamine. If therapy is to be discontinued in patients receiving a beta-blocker and clonidine concurrently, the beta-blocker should be withdrawn several days before the gradual discontinuation of Catapres tablets. Because children commonly have gastrointestinal illnesses that lead to vomiting, they may be particularly susceptible to hypertensive episodes resulting from abrupt inability to take medication. PRECAUTIONS General In patients who have developed localized contact sensitization to Catapres-TTS (clonidine), continuation of Catapres-TTS or substitution of oral clonidine hydrochloride therapy may be associated with the development of a generalized skin rash. In patients who develop an allergic reaction to Catapres-TTS, substitution of oral clonidine hydrochloride may also elicit an allergic reaction (including generalized rash, urticaria, or angioedema). Catapres tablets should be used with caution in patients with severe coronary insufficiency, conduction disturbances, recent myocardial infarction, cerebrovascular disease or chronic renal failure. Perioperative Use Administration of Catapres tablets should be continued to within four hours of surgery and resumed as soon as possible thereafter. Blood pressure should be carefully monitored during surgery and additional measures to control blood pressure should be available if required. Information for Patients Patients should be cautioned against interruption of Catapres tablets therapy without their physician's advice. Patients who engage in potentially hazardous activities, such as operating machinery or driving, should be advised of a possible sedative effect of clonidine. They should also be informed that this sedative effect may be increased by concomitant use of alcohol, barbiturates, or other sedating drugs. Patients who wear contact lenses should be cautioned that treatment with Catapres tablets may cause dryness of eyes. This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda NDA 17407/S-036 Page 7 Drug Interactions Clonidine may potentiate the CNS-depressive effects of alcohol, barbiturates or other sedating drugs. If a patient receiving clonidine hydrochloride is also taking tricyclic antidepressants, the hypotensive effect of clonidine may be reduced, necessitating an increase in the clonidine dose. Monitor heart rate in patients receiving clonidine concomitantly with agents known to affect sinus node function or AV nodal conduction, e.g., digitalis, calcium channel blockers, and beta- blockers. Sinus bradycardia resulting in hospitalization and pacemaker insertion has been reported in association with the use of clonidine concomitantly with diltiazem or verapamil. Amitriptyline in combination with clonidine enhances the manifestation of corneal lesions in rats (see Toxicology). Toxicology In several studies with oral clonidine hydrochloride, a dose-dependent increase in the incidence and severity of spontaneous retinal degeneration was seen in albino rats treated for six months or longer. Tissue distribution studies in dogs and monkeys showed a concentration of clonidine in the choroid. In view of the retinal degeneration seen in rats, eye examinations were performed during clinical trials in 908 patients before, and periodically after, the start of clonidine therapy. In 353 of these 908 patients, the eye examinations were carried out over periods of 24 months or longer. Except for some dryness of the eyes, no drug-related abnormal ophthalmological findings were recorded and, according to specialized tests such as electroretinography and macular dazzle, retinal function was unchanged. In combination with amitriptyline, clonidine hydrochloride administration led to the development of corneal lesions in rats within 5 days. Carcinogenesis, Mutagenesis, Impairment of Fertility Chronic dietary administration of clonidine was not carcinogenic to rats (132 weeks) or mice (78 weeks) dosed, respectively, at up to 46 or 70 times the maximum recommended daily human dose as mg/kg (9 or 6 times the MRDHD on a mg/m basis). There was no evidence of genotoxicity in the Ames test for mutagenicity or mouse micronucleus test for clastogenicity. Fertility of male or female rats was unaffected by clonidine doses as high as 150 mcg/kg (approximately 3 times MRDHD). In a separate experiment, fertility of female rats appeared to be affected at dose levels of 500 to 2000 mcg/kg (10 to 40 times the oral MRDHD on a mg/kg basis; 2 to 8 times the MRDHD on a mg/m basis). Pregnancy Teratogenic Effects: Pregnancy Category C. Reproduction studies performed in rabbits at doses up to approximately 3 times the oral maximum recommended daily human dose (MRDHD) of Catapres (clonidine hydrochloride, USP) tablets produced no evidence of a teratogenic or embryotoxic potential in rabbits. In rats, however, doses as low as 1/3 the oral MRDHD (1/15 the MRDHD on a mg/m basis) of clonidine This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda NDA 17407/S-036 Page 8 were associated with increased resorptions in a study in which dams were treated continuously from 2 months prior to mating. Increased resorptions were not associated with treatment at the same time or at higher dose levels (up to 3 times the oral MRDHD) when the dams were treated on gestation days 6-15. Increases in resorption were observed at much higher dose levels (40 times the oral MRDHD on a mg/kg basis; 4 to 8 times the MRDHD on a mg/m basis) in mice and rats treated on gestation days 1-14 (lowest dose employed in the study was 500 mcg/kg). No adequate, well-controlled studies have been conducted in pregnant women. Because animal reproduction studies are not always predictive of human response, this drug should be used during pregnancy only if clearly needed. Nursing Mothers As clonidine hydrochloride is excreted in human milk, caution should be exercised when Catapres (clonidine hydrochloride, USP) tablets are administered to a nursing woman. Pediatric Use Safety and effectiveness in pediatric patients have not been established in adequate and well- controlled trials (see WARNINGS, Withdrawal). ADVERSE REACTIONS Most adverse effects are mild and tend to diminish with continued therapy. The most frequent (which appear to be dose-related) are dry mouth, occurring in about 40 of 100 patients; drowsiness, about 33 in 100; dizziness, about 16 in 100; constipation and sedation, each about 10 in 100. The following less frequent adverse experiences have also been reported in patients receiving Catapres tablets, but in many cases patients were receiving concomitant medication and a causal relationship has not been established. Body as a Whole: Fatigue, fever, headache, pallor, weakness, and withdrawal syndrome. Also reported were a weakly positive Coombs’ test and increased sensitivity to alcohol. Cardiovascular: Bradycardia, congestive heart failure, electrocardiographic abnormalities (i.e.,sinus node arrest, junctional bradycardia, high degree AV block and arrhythmias), orthostatic symptoms, palpitations, Raynaud’s phenomenon, syncope, and tachycardia. Cases of sinus bradycardia and atrioventricular block have been reported, both with and without the use of concomitant digitalis. Central Nervous System: Agitation, anxiety, delirium, delusional perception, hallucinations (including visual and auditory), insomnia, mental depression, nervousness, other behavioral changes, paresthesia, restlessness, sleep disorder, and vivid dreams or nightmares. Dermatological: Alopecia, angioneurotic edema, hives, pruritus, rash, and urticaria. This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda NDA 17407/S-036 Page 9 Gastrointestinal: Abdominal pain, anorexia, constipation, hepatitis, malaise, mild transient abnormalities in liver function tests, nausea, parotitis, pseudo-obstruction (including colonic pseudo-obstruction), salivary gland pain, and vomiting. Genitourinary: Decreased sexual activity, difficulty in micturition, erectile dysfunction, loss of libido, nocturia, and urinary retention. Hematologic: Thrombocytopenia. Metabolic: Gynecomastia, transient elevation of blood glucose or serum creatine phosphokinase, and weight gain. Musculoskeletal: Leg cramps and muscle or joint pain. Oro-otolaryngeal: Dryness of the nasal mucosa. Ophthalmological: Accommodation disorder, blurred vision, burning of the eyes, decreased lacrimation, and dryness of eyes. OVERDOSAGE Hypertension may develop early and may be followed by hypotension, bradycardia, respiratory depression, hypothermia, drowsiness, decreased or absent reflexes, weakness, irritability and miosis. The frequency of CNS depression may be higher in children than adults. Large overdoses may result in reversible cardiac conduction defects or dysrhythmias, apnea, coma and seizures. Signs and symptoms of overdose generally occur within 30 minutes to two hours after exposure. As little as 0.1 mg of clonidine has produced signs of toxicity in children. There is no specific antidote for clonidine overdosage. Clonidine overdosage may result in the rapid development of CNS depression; therefore, induction of vomiting with ipecac syrup is not recommended. Gastric lavage may be indicated following recent and/or large ingestions. Administration of activated charcoal and/or a cathartic may be beneficial. Supportive care may include atropine sulfate for bradycardia, intravenous fluids and/or vasopressor agents for hypotension and vasodilators for hypertension. Naloxone may be a useful adjunct for the management of clonidine-induced respiratory depression, hypotension and/or coma; blood pressure should be monitored since the administration of naloxone has occasionally resulted in paradoxical hypertension. Tolazoline administration has yielded inconsistent results and is not recommended as first-line therapy. Dialysis is not likely to significantly enhance the elimination of clonidine. The largest overdose reported to date involved a 28-year old male who ingested 100 mg of clonidine hydrochloride powder. This patient developed hypertension followed by hypotension, bradycardia, apnea, hallucinations, semicoma, and premature ventricular contractions. The patient fully recovered after intensive treatment. Plasma clonidine levels were 60 ng/ml after 1 hour, 190 ng/ml after 1.5 hours, 370 ng/ml after 2 hours, and 120 ng/ml after 5.5 and 6.5 hours. In mice and rats, the oral LD of clonidine is 206 and 465 mg/kg, respectively. This label may not be the latest approved by FDA.

The following is a general guide to its administration. Initial Dose 0.1 mg tablet twice daily (morning and bedtime). Elderly patients may benefit from a lower initial dose. Maintenance Dose Further increments of 0.1 mg per day may be made at weekly intervals if necessary until the desired response is achieved. Taking the larger portion of the oral daily dose at bedtime may minimize transient adjustment effects of dry mouth and drowsiness. The therapeutic doses most commonly employed have ranged from 0.2 mg to 0.6 mg per day given in divided doses. Studies have indicated that 2.4 mg is the maximum effective daily dose, but doses as high as this have rarely been employed. Renal Impairment Dosage must be adjusted according to the degree of impairment, and patients should be carefully monitored. Since only a minimal amount of clonidine is removed during routine hemodialysis, there is no need to give supplemental clonidine following dialysis.

1 NSS-9A (O) NegGram ® Suspension1 NALIDIXIC ACID ORAL SUSPENSION1, USP To reduce the development of drug-resistant bacteria and maintain the effectiveness of NegGram (nalidixic acid, USP) and other antibacterial drugs, NegGram should be used only to treat or prevent infections that are proven or strongly suspected to be caused by bacteria. DESCRIPTION NegGram, brand of nalidixic acid, is a quinolone antibacterial agent for oral administration. Nalidixic acid is 1-ethyl-1, 4-dihydro-7-methyl-4-oxo-1, 8-naphthyridine-3- carboxylic acid. It is a pale yellow, crystalline substance and a very weak organic acid. Nalidixic acid has the following structural formula: Inactive Ingredients – Carbomere 934P, FD&C Red #40, Flavor, Parabens, Purified Water, Saccharin Sodium, Sodium Chloride, Sorbitol Solution. CLINICAL PHARMACOLOGY Following oral administration, NegGram is rapidly absorbed from the gastrointestinal tract, partially metabolized in the liver, and rapidly excreted through the kidneys. Unchanged nalidixic acid appears in the urine along with an active metabolite, hydroxynalidixic acid, which has antibacterial activity similar to that of nalidixic acid. Other metabolites include glucuronic acid conjugates of nalidixic acid and hydroxy nalidixic acid, and the dicarboxylic acid derivative. The hydroxy metabolite represents 30 percent of the biologically active drug in the blood and 85 percent in the urine. Peak serum levels of active drug average approximately 20 mcg to 40 mcg per mL (90 percent protein bound), one to two hours after administration of a 1 g dose to a 1 Insert is being revised to make it specific to NegGram Suspension. Previously the insert applied to both NegGram Caplets and NegGram Suspension. This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda 2 fasting normal individual, with a half-life of about 90 minutes. Peak urine levels of active drug average approximately 150 mcg to 200 mcg per mL, three to four hours after administration, with a half-life of about six hours. Approximately four percent of NegGram is excreted in the feces. Traces of nalidixic acid were found in blood and urine of an infant whose mother had received the drug during the last trimester of pregnancy. (See PRECAUTIONS—Drug Interactions.) Microbiology NegGram has marked antibacterial activity against gram-negative bacteria including Enterobacter species, Escherichia coli, Morganella Morganii; Proteus Mirabilis, Proteus vulgaris, and Providencia rettgeri. Pseudomonas species are generally resistant to the drug. NegGram is bactericidal and is effective over the entire urinary pH range. Conventional chromosomal resistance to NegGram taken in full dosage has been reported to emerge in approximately 2 to 14 percent of patients during treatment; however, bacterial resistance to NegGram has not been shown to be transferable via R factor. Susceptibility Test Diffusion Techniques: Quantitative methods that require measurement of zone diameters give the most precise estimates of antibacterial susceptibility. One such procedure recommended for use with a disc containing 30 mcg of nalidixic acid is the National Committee for Clinical Laboratory Standards (NCCLS) approved procedure. Only organisms from urinary tract infections should be tested. Results of laboratory tests using 30 mcg nalidixic acid discs should be interpreted using the following criteria: Zone Diameter (mm) Interpretation ≥19 (S) Susceptible 14-18 (I) Intermediate ≤13 (R) Resistant Dilution Techniques: Broth and agar dilution methods, such as those recommended by the NCCLS, may be used to determine the minimum inhibitory concentration (MIC) of nalidixic acid. MIC test results should be interpreted according to the following criteria: MIC (mcg/mL) Interpretation ≤16 (S) Susceptible ≥32 (R) Resistant For any susceptibility test, a report of "susceptible" indicates that the pathogen is likely to respond to nalidixic acid therapy. A report of "resistant" indicates that the pathogen is not likely to respond. A report of "intermediate" generally indicates that the test result is equivocal. The Quality Control strains should have the following assigned daily ranges for nalidixic acid: QC Strains E. Coli (ATCC 25922) Disc Zone Diameter 22-28 MIC (mcg/mL) This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda 3 1.0-4.0 INDICATIONS AND USAGE NegGram (nalidixic acid, USP) is indicated for the treatment of urinary tract infections caused by susceptible gram-negative microorganisms, including the majority of E. Coli, Enterobacter species, Klebsiella species, and Proteus species. Disc susceptibility testing with the 30 mcg disc should be performed prior to administration of the drug, and during treatment if clinical response warrants. To reduce the development of drug-resistant bacteria and maintain the effectiveness of NegGram and other antibacterial drugs, NegGram should be used only to treat or prevent infections that are proven or strongly suspected to be caused by susceptible bacteria. When culture and susceptibility information are available, they should be considered in selecting or modifying antibacterial therapy. In the absence of such data, local epidemiology and susceptibility patterns may contribute to the empiric selection of therapy. CONTRAINDICATIONS NegGram is contraindicated in patients with known hypersensitivity to nalidixic acid or to related compounds, infants less than three months of age, and in patients with porphyria or a history of convulsive disorders. NegGram is contraindicated in patients undergoing concomitant therapy with melphalan or other related cancer chemotherapeutic alkylating agents because of serious gastrointestinal toxicity such as hemorrhagic ulcerative colitis or intestinal necrosis. WARNINGS Central Nervous System (CNS) effects including convulsions, increased intracranial pressure, and toxic psychosis have been reported with nalidixic acid therapy. Convulsive seizures have been reported with other drugs in this class. Quinolones may also cause CNS stimulation which may lead to tremor, restlessness, lightheadedness, confusion, and hallucinations. Therefore, nalidixic acid should be used with caution in patients with known or suspected CNS disorders, such as, cerebral arteriosclerosis or epilepsy, or other factors which predispose seizures. (See ADVERSE REACTIONS.) If these reactions occur in patients receiving nalidixic acid, the drug should be discontinued and appropriate measures instituted. Serious and occasionally fatal hypersensitivity (anaphylactoid) reactions, some following the first dose, have been reported in patients receiving quinolone therapy. Some reactions were accompanied by cardiovascular collapse, loss of conscious-ness, tingling, pharyngeal or facial edema, dyspnea, urticaria, and itching. Only a few patients had a history of hypersensitivity reactions. Serious anaphylactoid reactions required immediate emergency treatment with epinephrine. Oxygen, intravenous steroids, and airway management, including intubation, should be administered as indicated. Nalidixic acid and other members of the quinolone drug class have been shown to cause arthropathy in juvenile animals. (See PRECAUTIONS and ANIMAL PHARMACOLOGY.) Pseudomembranous colitis has been reported with nearly all antibacterial agents, including quinolones, and may range in severity from mild to life-threatening. Therefore, it is important to consider this diagnosis in patients who present with diarrhea subsequent to the administration of antibacterial agents. This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda 4 Treatment with antibacterial agents alters the normal flora of the colon and may permit overgrowth of clostridia. Studies indicate that a toxin produced by Clostridium difficile is one primary cause of “antibiotic-associated colitis”. After the diagnosis of pseudomembranous colitis has been established, therapeutic measures should be initiated. Mild cases of pseudomembranous colitis usually respond to drug discontinuation alone. In moderate to severe cases, consideration should be given to management with fluids and electrolytes, protein supplementation, and treatment with an antibacterial drug clinically effective against C. difficile colitis. QT interval prolongation/torsades de pointes: Rare cases of torsades de pointes have been spontaneously reported during post-marketing surveillance in patients receiving quinolones, including nalidixic acid. These rare cases were associated with one or more of the following factors: age over 60, female gender, underlying cardiac disease, and/or use of multiple medications. Nalidixic acid should be avoided in patients with known prolongation of the QT interval, patients with uncorrected hypokalemia, and patients receiving class IA (quinidine, Procainamide), or class III (amiodarone, sotalol) antiarrhythmic agents.2 Peripheral neuropathy: Rare cases of sensory or sensorimotor axonal polyneuropathy affecting small and/or large axons resulting in paresthesias, hypoesthesias, dysesthesias and weakness have been reported in patients receiving quinolones, including nalidixic acid. Nalidixic acid should be discontinued if the patient experiences symptoms of neuropathy including pain, burning, tingling, numbness, and/or weakness, or is found to have deficits in light touch, pain, temperature, position sense, vibratory sensation, and/or motor strength in order to prevent the development of an irreversible condition. Tendon Effects: Ruptures of the shoulder, hand, Achilles tendon or other tendons that required surgical repair or resulted in prolonged disability have been reported in patients receiving quinolones, including nalidixic acid. Post-marketing surveillance reports indicate that this risk may be increased in patients receiving concomitant corticosteroids, especially in the elderly. Nalidixic acid should be discontinued if the patient experiences pain, inflammation, or rupture of a tendon. Patients should rest and refrain from exercise until the diagnosis of tendonitis or tendon rupture has been excluded. Tendon rupture can occur during or after therapy with quinolones, including nalidixic acid. PRECAUTIONS General Blood counts and renal and liver function tests should be performed periodically if treatment is continued for more than two weeks. NegGram should be used with caution in patients with liver disease, epilepsy, or severe cerebral arteriosclerosis. (See WARNINGS.) While caution should be used in patients with severe renal failure, therapeutic concentrations of NegGram in the urine, without increased toxicity due to drug accumulation in the blood, have been observed in patients on full dosage with creatinine clearances as low as 2 mL/minute to 8 mL/minute. 2 The QT interval prolongation/torsades de pointes paragraph is being removed as allowed by the FDA per the Quinolone Class Labeling This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda 5 Moderate to severe phototoxicity reactions have been observed in patients who are exposed to direct sunlight while receiving NegGram or other members of this drug class. Excessive sunlight should be avoided. Therapy should be discontinued if phototoxicity occurs. If bacterial resistance to NegGram emerges during treatment, it usually does so within 48 hours, permitting rapid change to another antimicrobial. Therefore, if the clinical response is unsatisfactory or if relapse occurs, cultures and sensitivity tests should be repeated. Underdosage with NegGram during initial treatment (with less than 4 g per day for adults) may predispose to emergence of bacterial resistance. (See DOSAGE AND ADMINISTRATION.) Cross-resistance between nalidixic acid and other quinolone derivatives such as oxolinic acid and cinoxacin has been observed Caution should be observed in patients with glucose-6-phosphate dehydrogenase deficiency. (see ADVERSE REACTIONS). Prescribing NegGram in the absence of a proven or strongly suspected bacterial infection or a prophylactic indication is unlikely to provide benefit to the patient and increases the risk of the development of drug-resistant bacteria. Information for Patients Patients should be advised NegGram may be taken with or without meals. Patients should be advised to drink fluids liberally and not take antacids. Patients should be advised that quinolones may be associated with hypersensitivity reactions, even following a single dose, and to discontinue the drug at the first sign of a skin rash or other allergic reactions. Quinolones may cause dizziness and light-headedness, therefore, patients should know how they react to NegGram before they operate an automobile or machinery or engage in activities requiring mental alertness or coordination. Patients should be advised that quinolones may increase the effects of theophylline and caffeine. There is a possibility of caffeine accumulation when products containing caffeine are consumed while taking quinolones. Patients should be advised to avoid excessive sunlight or artificial ultraviolet light while receiving nalidixic acid and to discontinue therapy if phototoxicity occurs. Patients should be advised that convulsions have been reported in patients taking quinolones, including nalidixic acid, and to notify their physician before taking this drug if there is a history of this condition. Patients should be advised that mineral supplements, vitamins with iron or minerals, calcium-, aluminum-, magnesium-based antacids, sucralfate or Videx® , (didanosine), chewable/buffered tablets of the pediatric powder for oral solution should not be taken within the two-hour period before or within the two-hour period after taking nalidixic acid (see Drug Interactions). Patients should be advised: • that nalidixic acid may cause changes in the electrocardiogram (QTc interval prolongation) • that nalidixic acid should be avoided in patients receiving class IA (e.g. quinidine, Procainamide) or class III (e.g. amiodarone, sotalol) antiarrhythmic agents • that nalidixic acid should be used with caution in subjects receiving drugs that affect the QTc interval such as cisapride, erythromycin, antipsychotics, and tricyclic antidepressant This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda 6 • to inform their physicians of any personal or family history of QTc prolongation or proarrhythmic conditions such as hypokalemia, bradycardia or recent myocardial ischemia • that peripheral neuropathies have been associated with nalidixic acid use. If symptoms of peripheral neuropathy including pain, burning, tingling, numbness, and/or weakness develop, they should discontinue treatment and contact their physicians. Patients should be counseled that antibacterial drugs including NegGram should only be used to treat bacterial infections. They do not treat viral infections (e.g., the common cold). When NegGram is prescribed to treat a bacterial infection, patients should be told that although it is common to feel better early in the course of therapy, the medication should be taken exactly as directed. Skipping doses or not completing the full course of therapy may (1) decrease the effectiveness of the immediate treatment and (2) increase the likelihood that bacteria will develop resistance and will not be treatable by NegGram or other antibacterial drugs in the future. Drug Interactions Elevated plasma levels of theophylline have been reported with concomitant quinolone use. There have been reports of theophylline-related side effects in patients on concomitant therapy with quinolones and theophylline. Therefore, monitoring of theophylline plasma levels should be considered and dosage of theophylline adjusted, as required. Quinolones have been shown to interfere with the metabolism of caffeine. This may lead to reduced clearance of caffeine and the prolongation of its plasma half-life. Quinolones, including nalidixic acid, may enhance the effects of the oral anticoagulant warfarin or its derivatives. When these products are administered concomitantly, prothrombin time or other suitable coagulation test should be closely monitored. Since active proliferation of organisms is a necessary condition for its antibacterial activity, the action of nalidixic acid may be inhibited by the presence of other antibacterial substances, especially bacteriostatic agents such as tetracycline, chloramphenicol, or nitrofurantoin, which is antagonistic to nalidixic acid in vitro. Probenecid inhibits the tubular secretion of nalidixic acid and may reduce its efficacy in the treatment of urinary tract infections while increasing the risk of systemic side effects. Serious gastrointestinal toxicity has been associated with the concomitant use of nalidixic acid and the anti-cancer drug melphalan. (see CONTRAINDICATIONS) Antacids containing magnesium, aluminum, or calcium; sucralfate or divalent or trivalent cations such as iron; multivitamins containing zinc; and Videx®, (Didanosine), chewable/buffered tablets or the pediatric powder for oral solution may substantially interfere with the absorption of quinolones, resulting in systemic levels considerably lower than desired. These agents should not be taken within the two-hour period before or within the two-hour period after nalidixic acid administration. Elevated serum levels of Cyclosporine have been reported with the concomitant use of some quinolones and cyclosporine. Therefore, cyclosporine serum levels should be monitored and appropriate Cyclosporine dosage adjustments made when these drugs are used concomitantly. This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda 7 Drug Laboratory Test Interactions When Benedict's or Fehling's solution or Clinitest® Reagent Tablets are used to test the urine of patients taking NegGram, a false-positive reaction for glucose may be obtained, due to the liberation of glucuronic acid from the metabolites excreted. However, a colorimetric test for glucose based on an enzyme reaction (e.g., with Clinistix® Reagent Strips or Tes-Tape® ) does not give a false-positive reaction to the liberated glucuronic acid. Incorrect values may be obtained for urinary 17-keto and ketogenic steroids in patients receiving NegGram, because of an interaction between the drug and the m-dinitrobenzene used in the usual assay method. In such cases, the Porter-Silber test for 17-hydroxycorticoids may be used. Carcinogenesis, Mutagenesis, Impairment of Fertility In lifetime studies in the rat given nalidixic acid in the diet, there was an increased incidence of preputial gland neoplasms in the treated males and clitoral gland neoplasms in the treated females. Studies in mice in which nalidixic acid was administered in the feed for two years, or was given in the feed for 76 weeks followed by no treatment for 9 weeks, gave equivocal evidence of carcinogenic activity. Nalidixic acid was tested in the Ames bacterial mutagenicity test (maximum dose 33 mcg/plate) and the mouse lymphoma assay (L5178Y/TK; maximum dose 100 mcg/mL) with and without metabolic activation, and results were negative. Pregnancy: Teratogenic Effects. Pregnancy Category C NegGram has been shown to be teratogenic and embryocidal in rats when given in oral doses six times the human dose. NegGram also prolonged the duration of pregnancy especially at four times the clinical dose. There are no adequate and well-controlled studies in pregnant women. Since nalidixic acid, like other drugs in this class, causes arthropathy in immature animals, NegGram should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus. (See WARNINGS and ANIMAL PHARMACOLOGY.) Nursing Mothers Since nalidixic acid is excreted in breast milk, it is contraindicated during lactation.3 Because of the potential for serious adverse reactions in nursing infants from NegGram, a decision should be made whether to discontinue nursing or to discontinue the drug taking into account the importance of the drug to the mother. Pediatric Use Safety and effectiveness in infants below the age of three months have not been established. Usage in Patients Under 18 Years of Age Toxicological studies have shown that nalidixic acid and related drugs can produce erosions of the cartilage in weight-bearing joints and other signs of arthropathy in immature animals of most species tested. No such joint lesions have been reported in humans to date. Nevertheless, until the significance of this finding is clarified, this drug should only be used in 3 There is evidence to show that nalidixic acid is excreted in human milk. Therefore, the revised language reflects current knowledge on the bioavailability of the drug. See Traeger A, Peiker G. Excretion of nalidixic acid via mother’s milk. Arch Toxicol 1980; Suppl. 4, 388-390. This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda 8 patients under 18 years of age when the potential benefit justifies the potential risk. If arthralgia occurs, treatment with nalidixic acid should be stopped. (See WARNINGS and ANIMAL PHARMACOLOGY.) Geriatric Use Clinical studies of NegGram® did not include sufficient numbers of subjects aged 65 and over to determine whether they respond differently from younger subjects. Other reported clinical experience has not identified differences in responses between the elderly and younger patients. Caution should therefore be observed in using nalidixic acid in elderly patients. This drug is known to be substantially excreted by the kidney, and the risk of toxic reactions to this drug may be greater in patients with impaired renal function. Because elderly patients are more likely to have decreased renal function, care should be taken in dose selection, and it may be useful to monitor renal function. (See PRECAUTIONS, General.) ADVERSE REACTIONS Reactions reported after oral administration of NegGram include the following. CNS effects: drowsiness, weakness, headache, and dizziness and vertigo. Reversible subjective visual disturbances without objective findings have occurred infrequently (generally with each dose during the first few days of treatment). These reactions include overbrightness of lights, change in color perception, difficulty in focusing, decrease in visual acuity, and double vision. They usually disappeared promptly when dosage was reduced or therapy was discontinued. Toxic psychosis or brief convulsions have been reported rarely, usually following excessive doses. In general, the convulsions have occurred in patients with predisposing factors such as epilepsy or cerebral arteriosclerosis. In infants and children receiving therapeutic doses of NegGram, increased intracranial pressure with bulging anterior fontanel, papilledema, and headache has occasionally been observed. A few cases of 6th cranial nerve palsy have been reported. Although the mechanisms of these reactions are unknown, the signs and symptoms usually disappeared rapidly with no sequelae when treatment was discontinued. Gastrointestinal: abdominal pain, nausea, vomiting, and diarrhea. Allergic: rash, pruritus, urticaria, angioedema, eosinophilia, arthralgia with joint stiffness and swelling, and anaphylactoid reaction, including anaphylactic shock. Erythema Multiforme and Stevens-Johnson syndrome have been reported with nalidixic acid and other drugs in this class. Rash was the most frequently reported adverse reaction. Photosensitivity reactions consisting of erythema and bullae on exposed skin surfaces usually resolve completely in 2 weeks to 2 months after NegGram is discontinued; however, bullae may continue to appear with successive exposures to sunlight or with mild skin trauma for up to 3 months after discontinuation of drug. (See PRECAUTIONS.) Other: rarely, cholestasis, paresthesia, metabolic acidosis, thrombocytopenia, leukopenia, or hemolytic anemia, sometimes associated with glucose 6-phosphate dehydrogenase deficiency and peripheral neuropathy. OVERDOSAGE Manifestations: Toxic psychosis, convulsions, increased intracranial pressure, or metabolic acidosis may occur in patients taking more than the recommended dosage. Vomiting, nausea, and lethargy may also occur following overdosage. This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda 9 Treatment: Reactions are short-lived (two to three hours) because the drug is rapidly excreted. If absorption has occurred, increased fluid administration is advisable and supportive measures such as oxygen and means of artificial respiration should be available. Although anticonvulsant therapy has not been used in the few instances of overdosage reported, it may be indicated in a severe case. DOSAGE AND ADMINISTRATION Antacids containing calcium, magnesium, or aluminum; sucralfate; divalent or trivalent cations such as iron; multivitamins containing zinc; or Videx® (Didanosine), chewable/buffered tablets of the pediatric powder for oral solution should not be taken within the two-hour period before or within the two-hour period after taking nalidixic acid. Adults. The recommended dosage for initial therapy in adults is 1 g administered four times daily for one or two weeks (total daily dose, 4 g). For prolonged therapy, the total daily dose may be reduced to 2 g after the initial treatment period. Underdosage during initial treatment may predispose to emergence of bacterial resistance. Pediatric Patients. Until further experience is gained, NegGram should not be administered to infants younger than three months. Dosage in pediatric patients 12 years of age and under should be calculated on the basis of body weight. The recommended total daily dosage for initial therapy is 25 mg/lb/day (55 mg/kg/day), administered in four equally divided doses. For prolonged therapy, the total daily dose may be reduced to 15 mg/lb/day (33 mg/kg/day). NegGram Suspension or NegGram Caplets of 250 mg may be used. One 250 mg caplet is equivalent to one teaspoon (5 mL) of the suspension. HOW SUPPLIED NegGram Suspension (nalidixic acid, USP) is supplied as: Suspension (250 mg / 5 mL), raspberry flavored, bottles of 1 pint (NDC 0024-1318-06) Store suspension at room temperature up to 25° C (77° F). ANIMAL PHARMACOLOGY NegGram (nalidixic acid) and related drugs have been shown to cause arthropathy in juvenile animals of most species tested. (See WARNINGS.) Long-term administration of nalidixic acid to rats resulted in retinal degeneration and cataracts. Hydroxynalidixic acid, the principal metabolite of NegGram, did not produce any oculotoxic effects at any dosage level in seven species of animals including three primate species. However, oral administration of this metabolite in high doses has been shown to have oculotoxic potential, namely in dogs and cats where it produced retinal degeneration upon prolonged administration leading, in some cases, to blindness. In experiments with NegGram itself, little if any such activity could be elicited in either dogs or cats. Sensitivity to CNS side effects in these species limited the doses of NegGram that This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda 10 could be used; this factor, together with a low conversion rate to the hydroxy metabolite in these species, may explain the absence of these effects.

Conventional chromosomal resistance to NegGram taken in full dosage has been reported to emerge in approximately 2 to 14 percent of patients during treatment; however, bacterial resistance to NegGram has not been shown to be transferable via R factor. Susceptibility Test Diffusion Techniques: Quantitative methods that require measurement of zone diameters give the most precise estimates of antibacterial susceptibility. One such procedure recommended for use with a disc containing 30 mcg of nalidixic acid is the National Committee for Clinical Laboratory Standards (NCCLS) approved procedure. Only organisms from urinary tract infections should be tested. Results of laboratory tests using 30 mcg nalidixic acid discs should be interpreted using the following criteria: Zone Diameter (mm) Interpretation ≥19 (S) Susceptible 14-18 (I) Intermediate ≤13 (R) Resistant Dilution Techniques: Broth and agar dilution methods, such as those recommended by the NCCLS, may be used to determine the minimum inhibitory concentration (MIC) of nalidixic acid. MIC test results should be interpreted according to the following criteria: MIC (mcg/mL) Interpretation ≤16 (S) Susceptible ≥32 (R) Resistant For any susceptibility test, a report of "susceptible" indicates that the pathogen is likely to respond to nalidixic acid therapy. A report of "resistant" indicates that the pathogen is not likely to respond. A report of "intermediate" generally indicates that the test result is equivocal. The Quality Control strains should have the following assigned daily ranges for nalidixic acid: QC Strains E. Coli (ATCC 25922) Disc Zone Diameter 22-28 MIC (mcg/mL) This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda 3 1.0-4.0 INDICATIONS AND USAGE NegGram (nalidixic acid, USP) is indicated for the treatment of urinary tract infections caused by susceptible gram-negative microorganisms, including the majority of E. Coli, Enterobacter species, Klebsiella species, and Proteus species. Disc susceptibility testing with the 30 mcg disc should be performed prior to administration of the drug, and during treatment if clinical response warrants. To reduce the development of drug-resistant bacteria and maintain the effectiveness of NegGram and other antibacterial drugs, NegGram should be used only to treat or prevent infections that are proven or strongly suspected to be caused by susceptible bacteria. When culture and susceptibility information are available, they should be considered in selecting or modifying antibacterial therapy. In the absence of such data, local epidemiology and susceptibility patterns may contribute to the empiric selection of therapy. CONTRAINDICATIONS NegGram is contraindicated in patients with known hypersensitivity to nalidixic acid or to related compounds, infants less than three months of age, and in patients with porphyria or a history of convulsive disorders. NegGram is contraindicated in patients undergoing concomitant therapy with melphalan or other related cancer chemotherapeutic alkylating agents because of serious gastrointestinal toxicity such as hemorrhagic ulcerative colitis or intestinal necrosis. WARNINGS Central Nervous System (CNS) effects including convulsions, increased intracranial pressure, and toxic psychosis have been reported with nalidixic acid therapy. Convulsive seizures have been reported with other drugs in this class. Quinolones may also cause CNS stimulation which may lead to tremor, restlessness, lightheadedness, confusion, and hallucinations. Therefore, nalidixic acid should be used with caution in patients with known or suspected CNS disorders, such as, cerebral arteriosclerosis or epilepsy, or other factors which predispose seizures. (See ADVERSE REACTIONS.) If these reactions occur in patients receiving nalidixic acid, the drug should be discontinued and appropriate measures instituted. Serious and occasionally fatal hypersensitivity (anaphylactoid) reactions, some following the first dose, have been reported in patients receiving quinolone therapy. Some reactions were accompanied by cardiovascular collapse, loss of conscious-ness, tingling, pharyngeal or facial edema, dyspnea, urticaria, and itching. Only a few patients had a history of hypersensitivity reactions. Serious anaphylactoid reactions required immediate emergency treatment with epinephrine. Oxygen, intravenous steroids, and airway management, including intubation, should be administered as indicated. Nalidixic acid and other members of the quinolone drug class have been shown to cause arthropathy in juvenile animals. (See PRECAUTIONS and ANIMAL PHARMACOLOGY.) Pseudomembranous colitis has been reported with nearly all antibacterial agents, including quinolones, and may range in severity from mild to life-threatening. Therefore, it is important to consider this diagnosis in patients who present with diarrhea subsequent to the administration of antibacterial agents. This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda 4 Treatment with antibacterial agents alters the normal flora of the colon and may permit overgrowth of clostridia. Studies indicate that a toxin produced by Clostridium difficile is one primary cause of “antibiotic-associated colitis”. After the diagnosis of pseudomembranous colitis has been established, therapeutic measures should be initiated. Mild cases of pseudomembranous colitis usually respond to drug discontinuation alone. In moderate to severe cases, consideration should be given to management with fluids and electrolytes, protein supplementation, and treatment with an antibacterial drug clinically effective against C. difficile colitis. QT interval prolongation/torsades de pointes: Rare cases of torsades de pointes have been spontaneously reported during post-marketing surveillance in patients receiving quinolones, including nalidixic acid. These rare cases were associated with one or more of the following factors: age over 60, female gender, underlying cardiac disease, and/or use of multiple medications. Nalidixic acid should be avoided in patients with known prolongation of the QT interval, patients with uncorrected hypokalemia, and patients receiving class IA (quinidine, Procainamide), or class III (amiodarone, sotalol) antiarrhythmic agents.2 Peripheral neuropathy: Rare cases of sensory or sensorimotor axonal polyneuropathy affecting small and/or large axons resulting in paresthesias, hypoesthesias, dysesthesias and weakness have been reported in patients receiving quinolones, including nalidixic acid. Nalidixic acid should be discontinued if the patient experiences symptoms of neuropathy including pain, burning, tingling, numbness, and/or weakness, or is found to have deficits in light touch, pain, temperature, position sense, vibratory sensation, and/or motor strength in order to prevent the development of an irreversible condition. Tendon Effects: Ruptures of the shoulder, hand, Achilles tendon or other tendons that required surgical repair or resulted in prolonged disability have been reported in patients receiving quinolones, including nalidixic acid. Post-marketing surveillance reports indicate that this risk may be increased in patients receiving concomitant corticosteroids, especially in the elderly. Nalidixic acid should be discontinued if the patient experiences pain, inflammation, or rupture of a tendon. Patients should rest and refrain from exercise until the diagnosis of tendonitis or tendon rupture has been excluded. Tendon rupture can occur during or after therapy with quinolones, including nalidixic acid. PRECAUTIONS General Blood counts and renal and liver function tests should be performed periodically if treatment is continued for more than two weeks. NegGram should be used with caution in patients with liver disease, epilepsy, or severe cerebral arteriosclerosis. (See WARNINGS.) While caution should be used in patients with severe renal failure, therapeutic concentrations of NegGram in the urine, without increased toxicity due to drug accumulation in the blood, have been observed in patients on full dosage with creatinine clearances as low as 2 mL/minute to 8 mL/minute. 2 The QT interval prolongation/torsades de pointes paragraph is being removed as allowed by the FDA per the Quinolone Class Labeling This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda 5 Moderate to severe phototoxicity reactions have been observed in patients who are exposed to direct sunlight while receiving NegGram or other members of this drug class. Excessive sunlight should be avoided. Therapy should be discontinued if phototoxicity occurs. If bacterial resistance to NegGram emerges during treatment, it usually does so within 48 hours, permitting rapid change to another antimicrobial. Therefore, if the clinical response is unsatisfactory or if relapse occurs, cultures and sensitivity tests should be repeated. Underdosage with NegGram during initial treatment (with less than 4 g per day for adults) may predispose to emergence of bacterial resistance. (See DOSAGE AND ADMINISTRATION.) Cross-resistance between nalidixic acid and other quinolone derivatives such as oxolinic acid and cinoxacin has been observed Caution should be observed in patients with glucose-6-phosphate dehydrogenase deficiency. (see ADVERSE REACTIONS). Prescribing NegGram in the absence of a proven or strongly suspected bacterial infection or a prophylactic indication is unlikely to provide benefit to the patient and increases the risk of the development of drug-resistant bacteria. Information for Patients Patients should be advised NegGram may be taken with or without meals. Patients should be advised to drink fluids liberally and not take antacids. Patients should be advised that quinolones may be associated with hypersensitivity reactions, even following a single dose, and to discontinue the drug at the first sign of a skin rash or other allergic reactions. Quinolones may cause dizziness and light-headedness, therefore, patients should know how they react to NegGram before they operate an automobile or machinery or engage in activities requiring mental alertness or coordination. Patients should be advised that quinolones may increase the effects of theophylline and caffeine. There is a possibility of caffeine accumulation when products containing caffeine are consumed while taking quinolones. Patients should be advised to avoid excessive sunlight or artificial ultraviolet light while receiving nalidixic acid and to discontinue therapy if phototoxicity occurs. Patients should be advised that convulsions have been reported in patients taking quinolones, including nalidixic acid, and to notify their physician before taking this drug if there is a history of this condition. Patients should be advised that mineral supplements, vitamins with iron or minerals, calcium-, aluminum-, magnesium-based antacids, sucralfate or Videx® , (didanosine), chewable/buffered tablets of the pediatric powder for oral solution should not be taken within the two-hour period before or within the two-hour period after taking nalidixic acid (see Drug Interactions). Patients should be advised: • that nalidixic acid may cause changes in the electrocardiogram (QTc interval prolongation) • that nalidixic acid should be avoided in patients receiving class IA (e.g. quinidine, Procainamide) or class III (e.g. amiodarone, sotalol) antiarrhythmic agents • that nalidixic acid should be used with caution in subjects receiving drugs that affect the QTc interval such as cisapride, erythromycin, antipsychotics, and tricyclic antidepressant This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda 6 • to inform their physicians of any personal or family history of QTc prolongation or proarrhythmic conditions such as hypokalemia, bradycardia or recent myocardial ischemia • that peripheral neuropathies have been associated with nalidixic acid use. If symptoms of peripheral neuropathy including pain, burning, tingling, numbness, and/or weakness develop, they should discontinue treatment and contact their physicians. Patients should be counseled that antibacterial drugs including NegGram should only be used to treat bacterial infections. They do not treat viral infections (e.g., the common cold). When NegGram is prescribed to treat a bacterial infection, patients should be told that although it is common to feel better early in the course of therapy, the medication should be taken exactly as directed. Skipping doses or not completing the full course of therapy may (1) decrease the effectiveness of the immediate treatment and (2) increase the likelihood that bacteria will develop resistance and will not be treatable by NegGram or other antibacterial drugs in the future. Drug Interactions Elevated plasma levels of theophylline have been reported with concomitant quinolone use. There have been reports of theophylline-related side effects in patients on concomitant therapy with quinolones and theophylline. Therefore, monitoring of theophylline plasma levels should be considered and dosage of theophylline adjusted, as required. Quinolones have been shown to interfere with the metabolism of caffeine. This may lead to reduced clearance of caffeine and the prolongation of its plasma half-life. Quinolones, including nalidixic acid, may enhance the effects of the oral anticoagulant warfarin or its derivatives. When these products are administered concomitantly, prothrombin time or other suitable coagulation test should be closely monitored. Since active proliferation of organisms is a necessary condition for its antibacterial activity, the action of nalidixic acid may be inhibited by the presence of other antibacterial substances, especially bacteriostatic agents such as tetracycline, chloramphenicol, or nitrofurantoin, which is antagonistic to nalidixic acid in vitro. Probenecid inhibits the tubular secretion of nalidixic acid and may reduce its efficacy in the treatment of urinary tract infections while increasing the risk of systemic side effects. Serious gastrointestinal toxicity has been associated with the concomitant use of nalidixic acid and the anti-cancer drug melphalan. (see CONTRAINDICATIONS) Antacids containing magnesium, aluminum, or calcium; sucralfate or divalent or trivalent cations such as iron; multivitamins containing zinc; and Videx®, (Didanosine), chewable/buffered tablets or the pediatric powder for oral solution may substantially interfere with the absorption of quinolones, resulting in systemic levels considerably lower than desired. These agents should not be taken within the two-hour period before or within the two-hour period after nalidixic acid administration. Elevated serum levels of Cyclosporine have been reported with the concomitant use of some quinolones and cyclosporine. Therefore, cyclosporine serum levels should be monitored and appropriate Cyclosporine dosage adjustments made when these drugs are used concomitantly. This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda 7 Drug Laboratory Test Interactions When Benedict's or Fehling's solution or Clinitest® Reagent Tablets are used to test the urine of patients taking NegGram, a false-positive reaction for glucose may be obtained, due to the liberation of glucuronic acid from the metabolites excreted. However, a colorimetric test for glucose based on an enzyme reaction (e.g., with Clinistix® Reagent Strips or Tes-Tape® ) does not give a false-positive reaction to the liberated glucuronic acid. Incorrect values may be obtained for urinary 17-keto and ketogenic steroids in patients receiving NegGram, because of an interaction between the drug and the m-dinitrobenzene used in the usual assay method. In such cases, the Porter-Silber test for 17-hydroxycorticoids may be used. Carcinogenesis, Mutagenesis, Impairment of Fertility In lifetime studies in the rat given nalidixic acid in the diet, there was an increased incidence of preputial gland neoplasms in the treated males and clitoral gland neoplasms in the treated females. Studies in mice in which nalidixic acid was administered in the feed for two years, or was given in the feed for 76 weeks followed by no treatment for 9 weeks, gave equivocal evidence of carcinogenic activity. Nalidixic acid was tested in the Ames bacterial mutagenicity test (maximum dose 33 mcg/plate) and the mouse lymphoma assay (L5178Y/TK; maximum dose 100 mcg/mL) with and without metabolic activation, and results were negative. Pregnancy: Teratogenic Effects. Pregnancy Category C NegGram has been shown to be teratogenic and embryocidal in rats when given in oral doses six times the human dose. NegGram also prolonged the duration of pregnancy especially at four times the clinical dose. There are no adequate and well-controlled studies in pregnant women. Since nalidixic acid, like other drugs in this class, causes arthropathy in immature animals, NegGram should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus. (See WARNINGS and ANIMAL PHARMACOLOGY.) Nursing Mothers Since nalidixic acid is excreted in breast milk, it is contraindicated during lactation.3 Because of the potential for serious adverse reactions in nursing infants from NegGram, a decision should be made whether to discontinue nursing or to discontinue the drug taking into account the importance of the drug to the mother. Pediatric Use Safety and effectiveness in infants below the age of three months have not been established. Usage in Patients Under 18 Years of Age Toxicological studies have shown that nalidixic acid and related drugs can produce erosions of the cartilage in weight-bearing joints and other signs of arthropathy in immature animals of most species tested. No such joint lesions have been reported in humans to date. Nevertheless, until the significance of this finding is clarified, this drug should only be used in 3 There is evidence to show that nalidixic acid is excreted in human milk. Therefore, the revised language reflects current knowledge on the bioavailability of the drug. See Traeger A, Peiker G. Excretion of nalidixic acid via mother’s milk. Arch Toxicol 1980; Suppl. 4, 388-390. This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda 8 patients under 18 years of age when the potential benefit justifies the potential risk. If arthralgia occurs, treatment with nalidixic acid should be stopped. (See WARNINGS and ANIMAL PHARMACOLOGY.) Geriatric Use Clinical studies of NegGram® did not include sufficient numbers of subjects aged 65 and over to determine whether they respond differently from younger subjects. Other reported clinical experience has not identified differences in responses between the elderly and younger patients. Caution should therefore be observed in using nalidixic acid in elderly patients. This drug is known to be substantially excreted by the kidney, and the risk of toxic reactions to this drug may be greater in patients with impaired renal function. Because elderly patients are more likely to have decreased renal function, care should be taken in dose selection, and it may be useful to monitor renal function. (See PRECAUTIONS, General.) ADVERSE REACTIONS Reactions reported after oral administration of NegGram include the following. CNS effects: drowsiness, weakness, headache, and dizziness and vertigo. Reversible subjective visual disturbances without objective findings have occurred infrequently (generally with each dose during the first few days of treatment). These reactions include overbrightness of lights, change in color perception, difficulty in focusing, decrease in visual acuity, and double vision. They usually disappeared promptly when dosage was reduced or therapy was discontinued. Toxic psychosis or brief convulsions have been reported rarely, usually following excessive doses. In general, the convulsions have occurred in patients with predisposing factors such as epilepsy or cerebral arteriosclerosis. In infants and children receiving therapeutic doses of NegGram, increased intracranial pressure with bulging anterior fontanel, papilledema, and headache has occasionally been observed. A few cases of 6th cranial nerve palsy have been reported. Although the mechanisms of these reactions are unknown, the signs and symptoms usually disappeared rapidly with no sequelae when treatment was discontinued. Gastrointestinal: abdominal pain, nausea, vomiting, and diarrhea. Allergic: rash, pruritus, urticaria, angioedema, eosinophilia, arthralgia with joint stiffness and swelling, and anaphylactoid reaction, including anaphylactic shock. Erythema Multiforme and Stevens-Johnson syndrome have been reported with nalidixic acid and other drugs in this class. Rash was the most frequently reported adverse reaction. Photosensitivity reactions consisting of erythema and bullae on exposed skin surfaces usually resolve completely in 2 weeks to 2 months after NegGram is discontinued; however, bullae may continue to appear with successive exposures to sunlight or with mild skin trauma for up to 3 months after discontinuation of drug. (See PRECAUTIONS.) Other: rarely, cholestasis, paresthesia, metabolic acidosis, thrombocytopenia, leukopenia, or hemolytic anemia, sometimes associated with glucose 6-phosphate dehydrogenase deficiency and peripheral neuropathy. OVERDOSAGE Manifestations: Toxic psychosis, convulsions, increased intracranial pressure, or metabolic acidosis may occur in patients taking more than the recommended dosage. Vomiting, nausea, and lethargy may also occur following overdosage. This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda 9 Treatment: Reactions are short-lived (two to three hours) because the drug is rapidly excreted. If absorption has occurred, increased fluid administration is advisable and supportive measures such as oxygen and means of artificial respiration should be available. Although anticonvulsant therapy has not been used in the few instances of overdosage reported, it may be indicated in a severe case. DOSAGE AND ADMINISTRATION Antacids containing calcium, magnesium, or aluminum; sucralfate; divalent or trivalent cations such as iron; multivitamins containing zinc; or Videx® (Didanosine), chewable/buffered tablets of the pediatric powder for oral solution should not be taken within the two-hour period before or within the two-hour period after taking nalidixic acid. Adults. The recommended dosage for initial therapy in adults is 1 g administered four times daily for one or two weeks (total daily dose, 4 g). For prolonged therapy, the total daily dose may be reduced to 2 g after the initial treatment period. Underdosage during initial treatment may predispose to emergence of bacterial resistance. Pediatric Patients. Until further experience is gained, NegGram should not be administered to infants younger than three months. Dosage in pediatric patients 12 years of age and under should be calculated on the basis of body weight. The recommended total daily dosage for initial therapy is 25 mg/lb/day (55 mg/kg/day), administered in four equally divided doses. For prolonged therapy, the total daily dose may be reduced to 15 mg/lb/day (33 mg/kg/day). NegGram Suspension or NegGram Caplets of 250 mg may be used. One 250 mg caplet is equivalent to one teaspoon (5 mL) of the suspension. HOW SUPPLIED NegGram Suspension (nalidixic acid, USP) is supplied as: Suspension (250 mg / 5 mL), raspberry flavored, bottles of 1 pint (NDC 0024-1318-06) Store suspension at room temperature up to 25° C (77° F). ANIMAL PHARMACOLOGY NegGram (nalidixic acid) and related drugs have been shown to cause arthropathy in juvenile animals of most species tested. (See WARNINGS.) Long-term administration of nalidixic acid to rats resulted in retinal degeneration and cataracts. Hydroxynalidixic acid, the principal metabolite of NegGram, did not produce any oculotoxic effects at any dosage level in seven species of animals including three primate species. However, oral administration of this metabolite in high doses has been shown to have oculotoxic potential, namely in dogs and cats where it produced retinal degeneration upon prolonged administration leading, in some cases, to blindness. In experiments with NegGram itself, little if any such activity could be elicited in either dogs or cats. Sensitivity to CNS side effects in these species limited the doses of NegGram that This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda 10 could be used; this factor, together with a low conversion rate to the hydroxy metabolite in these species, may explain the absence of these effects.

Minipress® Capsules (prazosin hydrochloride) For Oral Use DESCRIPTION MINIPRESS® (prazosin hydrochloride), a quinazoline derivative, is the first of a new chemical class of antihypertensives. It is the hydrochloride salt of 1-(4-amino-6,7-dimethoxy- 2-quinazolinyl)-4-(2-furoyl) piperazine and its structural formula is: S tr uc tu ral Formu la Molecular formula C19H21N5O4•HCl It is a white, crystalline substance, slightly soluble in water and isotonic saline, and has a molecular weight of 419.87. Each 1 mg capsule of MINIPRESS for oral use contains drug equivalent to 1 mg free base. Inert ingredients in the formulations are: hard gelatin capsules (which may contain Blue 1, Red 3, Red 28, Red 40, and other inert ingredients); magnesium stearate; sodium lauryl sulfate; starch; sucrose. CLINICAL PHARMACOLOGY The exact mechanism of the hypotensive action of prazosin is unknown. Prazosin causes a decrease in total peripheral resistance and was originally thought to have a direct relaxant action on vascular smooth muscle. Recent animal studies, however, have suggested that the vasodilator effect of prazosin is also related to blockade of 1 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda postsynaptic alpha-adrenoceptors. The results of dog forelimb experiments demonstrate that the peripheral vasodilator effect of prazosin is confined mainly to the level of the resistance vessels (arterioles). Unlike conventional alpha-blockers, the antihypertensive action of prazosin is usually not accompanied by a reflex tachycardia. Tolerance has not been observed to develop in long term therapy. Hemodynamic studies have been carried out in man following acute single dose administration and during the course of long term maintenance therapy. The results confirm that the therapeutic effect is a fall in blood pressure unaccompanied by a clinically significant change in cardiac output, heart rate, renal blood flow and glomerular filtration rate. There is no measurable negative chronotropic effect. In clinical studies to date, prazosin hydrochloride has not increased plasma renin activity. In man, blood pressure is lowered in both the supine and standing positions. This effect is most pronounced on the diastolic blood pressure. Following oral administration, human plasma concentrations reach a peak at about three hours with a plasma half-life of two to three hours. The drug is highly bound to plasma protein. Bioavailability studies have demonstrated that the total absorption relative to the drug in a 20% alcoholic solution is 90%, resulting in peak levels approximately 65% of that of the drug in solution. Animal studies indicate that prazosin hydrochloride is extensively metabolized, primarily by demethylation and conjugation, and excreted mainly via bile and feces. Less extensive human studies suggest similar metabolism and excretion in man. In clinical studies in which lipid profiles were followed, there were generally no adverse changes noted between pre- and post-treatment lipid levels. INDICATIONS AND USAGE MINIPRESS is indicated in the treatment of hypertension. It can be used alone or in combination with other antihypertensive drugs such as diuretics or beta-adrenergic blocking agents. CONTRAINDICATIONS MINIPRESS is contraindicated in patients with known sensitivity to quinazolines, prazosin, or any of the inert ingredients. WARNINGS As with all alpha-blockers, MINIPRESS may cause syncope with sudden loss of consciousness. In most cases, this is believed to be due to an excessive postural hypotensive effect, although occasionally the syncopal episode has been preceded by a bout of severe tachycardia with heart rates of 120–160 beats per 2 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda minute. Syncopal episodes have usually occurred within 30 to 90 minutes of the initial dose of the drug; occasionally, they have been reported in association with rapid dosage increases or the introduction of another antihypertensive drug into the regimen of a patient taking high doses of MINIPRESS. The incidence of syncopal episodes is approximately 1% in patients given an initial dose of 2 mg or greater. Clinical trials conducted during the investigational phase of this drug suggest that syncopal episodes can be minimized by limiting the initial dose of the drug to 1 mg, by subsequently increasing the dosage slowly, and by introducing any additional antihypertensive drugs into the patient’s regimen with caution (see DOSAGE AND ADMINISTRATION). Hypotension may develop in patients given MINIPRESS who are also receiving a beta-blocker such as propranolol. If syncope occurs, the patient should be placed in the recumbent position and treated supportively as necessary. This adverse effect is self-limiting and in most cases does not recur after the initial period of therapy or during subsequent dose titration. Patients should always be started on the 1 mg capsules of MINIPRESS. The 2 and 5 mg capsules are not indicated for initial therapy. More common than loss of consciousness are the symptoms often associated with lowering of the blood pressure, namely, dizziness and lightheadedness. The patient should be cautioned about these possible adverse effects and advised what measures to take should they develop. The patient should also be cautioned to avoid situations where injury could result should syncope occur during the initiation of MINIPRESS therapy. PRECAUTIONS General Intraoperative Floppy Iris Syndrome (IFIS) has been observed during cataract surgery in some patients treated with alpha-1 blockers. This variant of small pupil syndrome is characterized by the combination of a flaccid iris that billows in response to intraoperative irrigation currents, progressive intraoperative miosis despite preoperative dilation with standard mydriatic drugs, and potential prolapse of the iris toward the phacoemulsification incisions. The patient’s ophthalmologist should be prepared for possible modifications to the surgical technique, such as the utilization of iris hooks, iris dilator rings, or viscoelastic substances. There does not appear to be a benefit of stopping alpha-1 blocker therapy prior to cataract surgery. Information for Patients: Dizziness or drowsiness may occur after the first dose of this medicine. Avoid driving or performing hazardous tasks for the first 24 hours after taking this medicine or when the dose is increased. Dizziness, lightheadedness, or fainting may occur, especially when rising from a lying or sitting position. Getting up slowly may help lessen the problem. These effects may also occur if you drink alcohol, stand for long periods of time, exercise, or if the weather is hot. While taking MINIPRESS, be 3 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda careful in the amount of alcohol you drink. Also, use extra care during exercise or hot weather, or if standing for long periods. Check with your physician if you have any questions. Drug Interactions MINIPRESS has been administered without any adverse drug interaction in limited clinical experience to date with the following: (1) cardiac glycosides– digitalis and digoxin; (2) hypoglycemics–insulin, chlorpropamide, phenformin, tolazamide, and tolbutamide; (3) tranquilizers and sedatives–chlordiazepoxide, diazepam, and phenobarbital; (4) antigout–allopurinol, colchicine, and probenecid; (5) antiarrhythmics– procainamide, propranolol (see WARNINGS however), and quinidine; and (6) analgesics, antipyretics and anti-inflammatories–propoxyphene, aspirin, indomethacin, and phenylbutazone. Addition of a diuretic or other antihypertensive agent to MINIPRESS has been shown to cause an additive hypotensive effect. This effect can be minimized by reducing the MINIPRESS dose to 1 to 2 mg three times a day, by introducing additional antihypertensive drugs cautiously, and then by retitrating MINIPRESS based on clinical response. Concomitant administration of MINIPRESS with a phosphodiesterase-5 (PDE-5) inhibitor can result in additive blood pressure lowering effects and symptomatic hypotension (see DOSAGE AND ADMINISTRATION). Drug/Laboratory Test Interactions In a study on five patients given from 12 to 24 mg of prazosin per day for 10 to 14 days, there was an average increase of 42% in the urinary metabolite of norepinephrine and an average increase in urinary VMA of 17%. Therefore, false positive results may occur in screening tests for pheochromocytoma in patients who are being treated with prazosin. If an elevated VMA is found, prazosin should be discontinued and the patient retested after a month. Laboratory Tests In clinical studies in which lipid profiles were followed, there were generally no adverse changes noted between pre- and post-treatment lipid levels. Carcinogenesis, Mutagenesis, Impairment of Fertility: No carcinogenic potential was demonstrated in an 18 month study in rats with MINIPRESS at dose levels more than 225 times the usual maximum recommended human dose of 20 mg per day. MINIPRESS was not mutagenic in in vivo genetic toxicology studies. In a fertility and general reproductive performance study in rats, both males and females, treated with 75 mg/kg (225 times the usual maximum recommended human dose), demonstrated decreased fertility, while those treated with 25 mg/kg (75 times the usual maximum recommended human dose) did not. 4 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda In chronic studies (one year or more) of MINIPRESS in rats and dogs, testicular changes consisting of atrophy and necrosis occurred at 25 mg/kg/day (75 times the usual maximum recommended human dose). No testicular changes were seen in rats or dogs at 10 mg/kg/day (30 times the usual maximum recommended human dose). In view of the testicular changes observed in animals, 105 patients on long term MINIPRESS therapy were monitored for 17-ketosteroid excretion and no changes indicating a drug effect were observed. In addition, 27 males on MINIPRESS for up to 51 months did not have changes in sperm morphology suggestive of drug effect. Usage in Pregnancy: Pregnancy Category C. MINIPRESS has been shown to be associated with decreased litter size at birth, 1, 4, and 21 days of age in rats when given doses more than 225 times the usual maximum recommended human dose. No evidence of drug-related external, visceral, or skeletal fetal abnormalities were observed. No drug-related external, visceral, or skeletal abnormalities were observed in fetuses of pregnant rabbits and pregnant monkeys at doses more than 225 times and 12 times the usual maximum recommended human dose, respectively. The use of prazosin and a beta-blocker for the control of severe hypertension in 44 pregnant women revealed no drug-related fetal abnormalities or adverse effects. Therapy with prazosin was continued for as long as 14 weeks.1 Prazosin has also been used alone or in combination with other hypotensive agents in severe hypertension of pregnancy by other investigators. No fetal or neonatal abnormalities have been reported with the use of prazosin.2 There are no adequate and well controlled studies which establish the safety of MINIPRESS in pregnant women. MINIPRESS should be used during pregnancy only if the potential benefit justifies the potential risk to the mother and fetus. Nursing Mothers: MINIPRESS has been shown to be excreted in small amounts in human milk. Caution should be exercised when MINIPRESS is administered to a nursing woman. Usage in Children: Safety and effectiveness in children have not been established. ADVERSE REACTIONS Clinical trials were conducted on more than 900 patients. During these trials and subsequent marketing experience, the most frequent reactions associated with MINIPRESS therapy are: dizziness 10.3%, headache 7.8%, drowsiness 7.6%, lack of energy 6.9%, weakness 6.5%, palpitations 5.3%, and nausea 4.9%. In most instances, side effects have disappeared with continued therapy or have been tolerated with no decrease in dose of drug. Less frequent adverse reactions which are reported to occur in 1–4% of patients are: 5 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda Gastrointestinal: vomiting, diarrhea, constipation. Cardiovascular: edema, orthostatic hypotension, dyspnea, syncope. Central Nervous System: vertigo, depression, nervousness. Dermatologic: rash. Genitourinary: urinary frequency. EENT: blurred vision, reddened sclera, epistaxis, dry mouth, nasal congestion. In addition, fewer than 1% of patients have reported the following (in some instances, exact causal relationships have not been established): Gastrointestinal: abdominal discomfort and/or pain, liver function abnormalities, pancreatitis. Cardiovascular: tachycardia. Central Nervous System: paresthesia, hallucinations. Dermatologic: pruritus, alopecia, lichen planus. Genitourinary: incontinence, impotence, priapism. EENT: tinnitus. Other: diaphoresis, fever, positive ANA titer, arthralgia. Single reports of pigmentary mottling and serous retinopathy, and a few reports of cataract development or disappearance have been reported. In these instances, the exact causal relationship has not been established because the baseline observations were frequently inadequate. In more specific slit-lamp and funduscopic studies, which included adequate baseline examinations, no drug-related abnormal ophthalmological findings have been reported. Literature reports exist associating MINIPRESS therapy with a worsening of pre-existing narcolepsy. A causal relationship is uncertain in these cases. In post-marketing experience, the following adverse events have been reported: Autonomic Nervous System: flushing. Body As A Whole: allergic reaction, asthenia, malaise, pain. 6 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda Cardiovascular, General: angina pectoris, hypotension. Endocrine: gynecomastia. Heart Rate/Rhythm: bradycardia. Psychiatric: insomnia. Skin/Appendages: urticaria. Vascular (Extracardiac): vasculitis. Vision: eye pain. Special Senses: During cataract surgery, a variant of small pupil syndrome known as Intraoperative Floppy Iris Syndrome (IFIS) has been reported in association with alpha­ 1 blocker therapy (see PRECAUTIONS). OVERDOSAGE Accidental ingestion of at least 50 mg of MINIPRESS in a two year old child resulted in profound drowsiness and depressed reflexes. No decrease in blood pressure was noted. Recovery was uneventful. Should overdosage lead to hypotension, support of the cardiovascular system is of first importance. Restoration of blood pressure and normalization of heart rate may be accomplished by keeping the patient in the supine position. If this measure is inadequate, shock should first be treated with volume expanders. If necessary, vasopressors should then be used. Renal function should be monitored and supported as needed. Laboratory data indicate MINIPRESS is not dialysable because it is protein bound. DOSAGE AND ADMINISTRATION The dose of MINIPRESS should be adjusted according to the patient’s individual blood pressure response. The following is a guide to its administration: Initial Dose 1 mg two or three times a day (see WARNINGS.) Maintenance Dose Dosage may be slowly increased to a total daily dose of 20 mg given in divided doses. The therapeutic dosages most commonly employed have ranged from 6 mg to 15 mg daily given in divided doses. Doses higher than 20 mg usually do not increase efficacy, however a few patients may benefit from further increases up to a daily dose of 40 mg 7 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda given in divided doses. After initial titration some patients can be maintained adequately on a twice daily dosage regimen. Use With Other Drugs When adding a diuretic or other antihypertensive agent, the dose of MINIPRESS should be reduced to 1 mg or 2 mg three times a day and retitration then carried out. Concomitant administration of MINIPRESS with a PDE-5 inhibitor can result in additive blood pressure lowering effects and symptomatic hypotension; therefore, PDE-5 inhibitor therapy should be initiated at the lowest dose in patients taking MINIPRESS.

Minipress® Capsules (prazosin hydrochloride) For Oral Use DESCRIPTION MINIPRESS® (prazosin hydrochloride), a quinazoline derivative, is the first of a new chemical class of antihypertensives. It is the hydrochloride salt of 1-(4-amino-6,7-dimethoxy­ 2-quinazolinyl)-4-(2-furoyl) piperazine and its structural formula is: struc tural f or mu la Molecular formula C19H21N5O4 HCl It is a white, crystalline substance, slightly soluble in water and isotonic saline, and has a molecular weight of 419.87. Each 1 mg capsule of MINIPRESS for oral use contains drug equivalent to 1 mg free base. Inert ingredients in the formulations are: hard gelatin capsules (which may contain Blue 1, Red 3, Red 28, Red 40, and other inert ingredients); magnesium stearate; sodium lauryl sulfate; starch; sucrose. CLINICAL PHARMACOLOGY The exact mechanism of the hypotensive action of prazosin is unknown. Prazosin causes a decrease in total peripheral resistance and was originally thought to have a direct relaxant action on vascular smooth muscle. Recent animal studies, however, have suggested that the vasodilator effect of prazosin is also related to blockade of postsynaptic alpha-adrenoceptors. The results of dog forelimb experiments demonstrate that the peripheral vasodilator effect of prazosin is 1 Reference ID: 3401095 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda confined mainly to the level of the resistance vessels (arterioles). Unlike conventional alpha-blockers, the antihypertensive action of prazosin is usually not accompanied by a reflex tachycardia. Tolerance has not been observed to develop in long term therapy. Hemodynamic studies have been carried out in man following acute single dose administration and during the course of long term maintenance therapy. The results confirm that the therapeutic effect is a fall in blood pressure unaccompanied by a clinically significant change in cardiac output, heart rate, renal blood flow and glomerular filtration rate. There is no measurable negative chronotropic effect. In clinical studies to date, prazosin hydrochloride has not increased plasma renin activity. In man, blood pressure is lowered in both the supine and standing positions. This effect is most pronounced on the diastolic blood pressure. Following oral administration, human plasma concentrations reach a peak at about three hours with a plasma half-life of two to three hours. The drug is highly bound to plasma protein. Bioavailability studies have demonstrated that the total absorption relative to the drug in a 20% alcoholic solution is 90%, resulting in peak levels approximately 65% of that of the drug in solution. Animal studies indicate that prazosin hydrochloride is extensively metabolized, primarily by demethylation and conjugation, and excreted mainly via bile and feces. Less extensive human studies suggest similar metabolism and excretion in man. In clinical studies in which lipid profiles were followed, there were generally no adverse changes noted between pre- and post-treatment lipid levels. INDICATIONS AND USAGE MINIPRESS is indicated for the treatment of hypertension, to lower blood pressure. Lowering blood pressure reduces the risk of fatal and nonfatal cardiovascular events, primarily strokes and myocardial infarctions. These benefits have been seen in controlled trials of antihypertensive drugs from a wide variety of pharmacologic classes, including this drug. Control of high blood pressure should be part of comprehensive cardiovascular risk management, including, as appropriate, lipid control, diabetes management, antithrombotic therapy, smoking cessation, exercise, and limited sodium intake. Many patients will require more than one drug to achieve blood pressure goals. For specific advice on goals and management, see published guidelines, such as those of the National High Blood Pressure Education Program’s Joint National Committee on Prevention, Detection, Evaluation, and Treatment of High Blood Pressure (JNC). Numerous antihypertensive drugs, from a variety of pharmacologic classes and with different mechanisms of action, have been shown in randomized controlled trials to reduce cardiovascular morbidity and mortality, and it can be concluded that it is blood pressure reduction, and not some other pharmacologic property of the drugs, that is largely responsible for those benefits. The largest and most consistent cardiovascular outcome benefit has been a reduction in the risk of 2 Reference ID: 3401095 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda stroke, but reductions in myocardial infarction and cardiovascular mortality also have been seen regularly. Elevated systolic or diastolic pressure causes increased cardiovascular risk, and the absolute risk increase per mmHg is greater at higher blood pressures, so that even modest reductions of severe hypertension can provide substantial benefit. Relative risk reduction from blood pressure reduction is similar across populations with varying absolute risk, so the absolute benefit is greater in patients who are at higher risk independent of their hypertension (for example, patients with diabetes or hyperlipidemia), and such patients would be expected to benefit from more aggressive treatment to a lower blood pressure goal. Some antihypertensive drugs have smaller blood pressure effects (as monotherapy) in black patients, and many antihypertensive drugs have additional approved indications and effects (e.g., on angina, heart failure, or diabetic kidney disease). These considerations may guide selection of therapy. MINIPRESS can be used alone or in combination with other antihypertensive drugs such as diuretics or beta-adrenergic blocking agents. CONTRAINDICATIONS MINIPRESS is contraindicated in patients with known sensitivity to quinazolines, prazosin, or any of the inert ingredients. WARNINGS As with all alpha-blockers, MINIPRESS may cause syncope with sudden loss of consciousness. In most cases, this is believed to be due to an excessive postural hypotensive effect, although occasionally the syncopal episode has been preceded by a bout of severe tachycardia with heart rates of 120–160 beats per minute. Syncopal episodes have usually occurred within 30 to 90 minutes of the initial dose of the drug; occasionally, they have been reported in association with rapid dosage increases or the introduction of another antihypertensive drug into the regimen of a patient taking high doses of MINIPRESS. The incidence of syncopal episodes is approximately 1% in patients given an initial dose of 2 mg or greater. Clinical trials conducted during the investigational phase of this drug suggest that syncopal episodes can be minimized by limiting the initial dose of the drug to 1 mg, by subsequently increasing the dosage slowly, and by introducing any additional antihypertensive drugs into the patient’s regimen with caution (see DOSAGE AND ADMINISTRATION). Hypotension may develop in patients given MINIPRESS who are also receiving a beta-blocker such as propranolol. If syncope occurs, the patient should be placed in the recumbent position and treated supportively as necessary. This adverse effect is self-limiting and in most cases does not recur after the initial period of therapy or during subsequent dose titration. 3 Reference ID: 3401095 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda Patients should always be started on the 1 mg capsules of MINIPRESS. The 2 and 5 mg capsules are not indicated for initial therapy. More common than loss of consciousness are the symptoms often associated with lowering of the blood pressure, namely, dizziness and lightheadedness. The patient should be cautioned about these possible adverse effects and advised what measures to take should they develop. The patient should also be cautioned to avoid situations where injury could result should syncope occur during the initiation of MINIPRESS therapy. PRECAUTIONS General Intraoperative Floppy Iris Syndrome (IFIS) has been observed during cataract surgery in some patients treated with alpha-1 blockers. This variant of small pupil syndrome is characterized by the combination of a flaccid iris that billows in response to intraoperative irrigation currents, progressive intraoperative miosis despite preoperative dilation with standard mydriatic drugs, and potential prolapse of the iris toward the phacoemulsification incisions. The patient’s ophthalmologist should be prepared for possible modifications to the surgical technique, such as the utilization of iris hooks, iris dilator rings, or viscoelastic substances. There does not appear to be a benefit of stopping alpha-1 blocker therapy prior to cataract surgery. Information for Patients: Dizziness or drowsiness may occur after the first dose of this medicine. Avoid driving or performing hazardous tasks for the first 24 hours after taking this medicine or when the dose is increased. Dizziness, lightheadedness, or fainting may occur, especially when rising from a lying or sitting position. Getting up slowly may help lessen the problem. These effects may also occur if you drink alcohol, stand for long periods of time, exercise, or if the weather is hot. While taking MINIPRESS, be careful in the amount of alcohol you drink. Also, use extra care during exercise or hot weather, or if standing for long periods. Check with your physician if you have any questions. Drug Interactions MINIPRESS has been administered without any adverse drug interaction in limited clinical experience to date with the following: (1) cardiac glycosides– digitalis and digoxin; (2) hypoglycemics–insulin, chlorpropamide, phenformin, tolazamide, and tolbutamide; (3) tranquilizers and sedatives–chlordiazepoxide, diazepam, and phenobarbital; (4) antigout– allopurinol, colchicine, and probenecid; (5) antiarrhythmics–procainamide, propranolol (see WARNINGS however), and quinidine; and (6) analgesics, antipyretics and anti-inflammatories– propoxyphene, aspirin, indomethacin, and phenylbutazone. Addition of a diuretic or other antihypertensive agent to MINIPRESS has been shown to cause an additive hypotensive effect. This effect can be minimized by reducing the MINIPRESS dose to 1 to 2 mg three times a day, by introducing additional antihypertensive drugs cautiously, and then by retitrating MINIPRESS based on clinical response. 4 Reference ID: 3401095 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda Concomitant administration of MINIPRESS with a phosphodiesterase-5 (PDE-5) inhibitor can result in additive blood pressure lowering effects and symptomatic hypotension (see DOSAGE AND ADMINISTRATION). Drug/Laboratory Test Interactions In a study on five patients given from 12 to 24 mg of prazosin per day for 10 to 14 days, there was an average increase of 42% in the urinary metabolite of norepinephrine and an average increase in urinary VMA of 17%. Therefore, false positive results may occur in screening tests for pheochromocytoma in patients who are being treated with prazosin. If an elevated VMA is found, prazosin should be discontinued and the patient retested after a month. Laboratory Tests In clinical studies in which lipid profiles were followed, there were generally no adverse changes noted between pre- and post-treatment lipid levels. Carcinogenesis, Mutagenesis, Impairment of Fertility: No carcinogenic potential was demonstrated in an 18 month study in rats with MINIPRESS at dose levels more than 225 times the usual maximum recommended human dose of 20 mg per day. MINIPRESS was not mutagenic in in vivo genetic toxicology studies. In a fertility and general reproductive performance study in rats, both males and females, treated with 75 mg/kg (225 times the usual maximum recommended human dose), demonstrated decreased fertility, while those treated with 25 mg/kg (75 times the usual maximum recommended human dose) did not. In chronic studies (one year or more) of MINIPRESS in rats and dogs, testicular changes consisting of atrophy and necrosis occurred at 25 mg/kg/day (75 times the usual maximum recommended human dose). No testicular changes were seen in rats or dogs at 10 mg/kg/day (30 times the usual maximum recommended human dose). In view of the testicular changes observed in animals, 105 patients on long term MINIPRESS therapy were monitored for 17-ketosteroid excretion and no changes indicating a drug effect were observed. In addition, 27 males on MINIPRESS for up to 51 months did not have changes in sperm morphology suggestive of drug effect. Usage in Pregnancy: Pregnancy Category C. MINIPRESS has been shown to be associated with decreased litter size at birth, 1, 4, and 21 days of age in rats when given doses more than 225 times the usual maximum recommended human dose. No evidence of drug-related external, visceral, or skeletal fetal abnormalities were observed. No drug-related external, visceral, or skeletal abnormalities were observed in fetuses of pregnant rabbits and pregnant monkeys at doses more than 225 times and 12 times the usual maximum recommended human dose, respectively. The use of prazosin and a beta-blocker for the control of severe hypertension in 44 pregnant women revealed no drug-related fetal abnormalities or adverse effects. Therapy with prazosin was continued for as long as 14 weeks.1 5 Reference ID: 3401095 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda Prazosin has also been used alone or in combination with other hypotensive agents in severe hypertension of pregnancy by other investigators. No fetal or neonatal abnormalities have been reported with the use of prazosin.2 There are no adequate and well controlled studies which establish the safety of MINIPRESS in pregnant women. MINIPRESS should be used during pregnancy only if the potential benefit justifies the potential risk to the mother and fetus. Nursing Mothers: MINIPRESS has been shown to be excreted in small amounts in human milk. Caution should be exercised when MINIPRESS is administered to a nursing woman. Usage in Children: Safety and effectiveness in children have not been established. ADVERSE REACTIONS Clinical trials were conducted on more than 900 patients. During these trials and subsequent marketing experience, the most frequent reactions associated with MINIPRESS therapy are: dizziness 10.3%, headache 7.8%, drowsiness 7.6%, lack of energy 6.9%, weakness 6.5%, palpitations 5.3%, and nausea 4.9%.

NDA 17443/S-/S-043/S-046/S-048/S-049 Page 7 Dantrium (dantrolene sodium) capsules Dantrium (dantrolene sodium) has a potential for hepatotoxicity, and should not be used in conditions other than those recommended. Symptomatic hepatitis (fatal and non­ fatal) has been reported at various dose levels of the drug. The incidence reported in patients taking up to 400 mg/day is much lower than in those taking doses of 800 mg or more per day. Even sporadic short courses of these higher dose levels within a treatment regimen markedly increased the risk of serious hepatic injury. Liver dysfunction as evidenced by blood chemical abnormalities alone (liver enzyme elevations) has been observed in patients exposed to Dantrium for varying periods of time. Overt hepatitis has occurred at varying intervals after initiation of therapy, but has been most frequently observed between the third and twelfth month of therapy. The risk of hepatic injury appears to be greater in females, in patients over 35 years of age, and in patients taking other medication(s) in addition to Dantrium (dantrolene sodium). Spontaneous reports suggest a higher proportion of hepatic events with fatal outcome in elderly patients receiving Dantrium. However, the majority of these cases were complicated with confounding factors such as intercurrent illnesses and/or concomitant potentially hepatotoxic medications (see Geriatric Use subsection). Dantrium should be used only in conjunction with appropriate monitoring of hepatic function including frequent determination of SGOT or SGPT. If no observable benefit is derived from the administration of Dantrium after a total of 45 days, therapy should be discontinued. The lowest possible effective dose for the individual patient should be prescribed. DESCRIPTION The chemical formula of Dantrium (dantrolene sodium) is hydrated 1-[[[5-(4-nitrophenyl)-2­ furanyl]methylene]amino]-2, 4-imidazolidinedione sodium salt. It is an orange powder, slightly soluble in water, but due to its slightly acidic nature the solubility increases somewhat in alkaline solution. The anhydrous salt has a molecular weight of 336. The hydrated salt contains approximately 15% water (3-1/2 moles) and has a molecular weight of 399. The structural formula for the hydrated salt is: stru ctu ra l fo rmula Dantrium is supplied in capsules of 25 mg, 50 mg, and 100 mg. Inactive Ingredients: Each capsule contains edible black ink, FD&C Yellow No.6, gelatin, lactose, magnesium stearate, starch, synthetic iron oxide red, synthetic iron oxide yellow, talc and titanium dioxide., CLINICAL PHARMACOLOGY In isolated nerve-muscle preparation, Dantrium has been shown to produce relaxation by affecting the contractile response of the skeletal muscle at a site beyond the myoneural junction, directly on the muscle itself. In skeletal muscle, Dantrium dissociates the excitation-contraction coupling, probably by interfering with the release of Ca++ from the sarcoplasmic reticulum. This effect appears to be more pronounced in fast muscle fibers as compared to slow ones, but Reference ID: 3100954 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda NDA 17443/S-/S-043/S-046/S-048/S-049 Page 8 generally affects both. A central nervous system effect occurs, with drowsiness, dizziness, and generalized weakness occasionally present. Although Dantrium does not appear to directly affect the CNS, the extent of its indirect effect is unknown. The absorption of Dantrium after oral administration in humans is incomplete and slow but consistent, and dose-related blood levels are obtained. The duration and intensity of skeletal muscle relaxation is related to the dosage and blood levels. The mean biologic half-life of Dantrium in adults is 8.7 hours after a 100-mg dose. Specific metabolic pathways in the degradation and elimination of Dantrium in human subjects have been established. Metabolic patterns are similar in adults and pediatric patients. In addition to the parent compound, dantrolene, which is found in measurable amounts in blood and urine, the major metabolites noted in body fluids are the 5-hydroxy analog and the acetamido analog. Since Dantrium is probably metabolized by hepatic microsomal enzymes, enhancement of its metabolism by other drugs is possible. However, neither phenobarbital nor diazepam appears to affect Dantrium metabolism. Clinical experience in the management of fulminant human malignant hyperthermia, as well as experiments conducted in malignant hyperthermia susceptible swine, have revealed that the administration of intravenous dantrolene, combined with indicated supportive measures, is effective in reversing the hypermetabolic process of malignant hyperthermia. Known differences between human and swine malignant hyperthermia are minor. The prophylactic administration of oral or intravenous dantrolene to malignant hyperthermia susceptible swine will attenuate or prevent the development of signs of malignant hyperthermia in a manner dependent upon the dosage of dantrolene administered and the intensity of the malignant hyperthermia triggering stimulus. Limited clinical experience with the administration of oral dantrolene to patients judged malignant hyperthermia susceptible, when combined with clinical experience in the use of intravenous dantrolene for the treatment of malignant hyperthermia and data derived from the above cited animal model experiments, suggests that oral dantrolene will also attenuate or prevent the development of signs of human malignant hyperthermia, provided that currently accepted practices in the management of such patients are adhered to (see INDICATIONS AND USAGE); intravenous dantrolene should also be available for use should the signs of malignant hyperthermia appear. INDICATIONS AND USAGE In Chronic Spasticity: Dantrium is indicated in controlling the manifestations of clinical spasticity resulting from upper motor neuron disorders (e.g., spinal cord injury, stroke, cerebral palsy, or multiple sclerosis). It is of particular benefit to the patient whose functional rehabilitation has been retarded by the sequelae of spasticity. Such patients must have presumably reversible spasticity where relief of spasticity will aid in restoring residual function. Dantrium is not indicated in the treatment of skeletal muscle spasm resulting from rheumatic disorders. If improvement occurs, it will ordinarily occur within the dosage titration (see DOSAGE AND ADMINISTRATION), and will be manifested by a decrease in the severity of spasticity and the ability to resume a daily function not quite attainable without Dantrium. Occasionally, subtle but meaningful improvement in spasticity may occur with Dantrium therapy. In such instances, information regarding improvement should be solicited from the patient and those who are in constant daily contact and attendance with him. Brief withdrawal of Dantrium for a period of 2 to 4 days will frequently demonstrate exacerbation of the manifestations of spasticity and may serve to confirm a clinical impression.

For current labeling information, please visit https://www.fda.gov/drugsatfda NDA 17443/S-/S-043/S-046/S-048/S-049 Page 9 A decision to continue the administration of Dantrium on a long-term basis is justified if introduction of the drug into the patient's regimen: produces a significant reduction in painful and/or disabling spasticity such as clonus, or permits a significant reduction in the intensity and/or degree of nursing care required, or rids the patient of any annoying manifestation of spasticity considered important by the patient himself. In Malignant Hyperthermia: Oral Dantrium is also indicated preoperatively to prevent or attenuate the development of signs of malignant hyperthermia in known, or strongly suspect, malignant hyperthermia susceptible patients who require anesthesia and/or surgery. Currently accepted clinical practices in the management of such patients must still be adhered to (careful monitoring for early signs of malignant hyperthermia, minimizing exposure to triggering mechanisms and prompt use of intravenous dantrolene sodium and indicated supportive measures should signs of malignant hyperthermia appear); see also the package insert for Dantrium® (dantrolene sodium) Intravenous. Oral Dantrium should be administered following a malignant hyperthermic crisis to prevent recurrence of the signs of malignant hyperthermia. CONTRAINDICATIONS Active hepatic disease, such as hepatitis and cirrhosis, is a contraindication for use of Dantrium. Dantrium is contraindicated where spasticity is utilized to sustain upright posture and balance in locomotion or whenever spasticity is utilized to obtain or maintain increased function. WARNINGS It is important to recognize that fatal and non-fatal liver disorders of an idiosyncratic or hypersensitivity type may occur with Dantrium therapy. At the start of Dantrium therapy, it is desirable to do liver function studies (SGOT, SGPT, alkaline phosphatase, total bilirubin) for a baseline or to establish whether there is pre-existing liver disease. If baseline liver abnormalities exist and are confirmed, there is a clear possibility that the potential for Dantrium hepatotoxicity could be enhanced, although such a possibility has not yet been established. Liver function studies (e.g., SGOT or SGPT) should be performed at appropriate intervals during Dantrium therapy. If such studies reveal abnormal values, therapy should generally be discontinued. Only where benefits of the drug have been of major importance to the patient, should reinitiation or continuation of therapy be considered. Some patients have revealed a return to normal laboratory values in the face of continued therapy while others have not. If symptoms compatible with hepatitis, accompanied by abnormalities in liver function tests or jaundice appear, Dantrium should be discontinued. If caused by Dantrium and detected early, the abnormalities in liver function characteristically have reverted to normal when the drug was discontinued.

If such reinstitution of therapy is done, it should be attempted only in patients who clearly need Dantrium and only after previous symptoms and laboratory abnormalities have cleared. The patient should be hospitalized and the drug should be restarted in very small and gradually increasing doses. Laboratory monitoring should be frequent and the drug should be withdrawn immediately if there is any indication of recurrent liver involvement. Some patients have reacted with unmistakable signs of liver abnormality upon administration of a challenge dose, while others have not. Dantrium should be used with particular caution in females and in patients over 35 years of age in view of apparent greater likelihood of drug-induced, potentially fatal, hepatocellular disease in these groups. Spontaneous reports suggest a higher proportion of hepatic events with fatal outcome in elderly patients receiving Dantrium. However, the majority of these cases were complicated with confounding factors such as intercurrent illnesses and/or concomitant potentially hepatotoxic medications (see Geriatric Use subsection). Carcinogenesis, Mutagenesis, Impairment of Fertility: Long-term safety of Dantrium in humans has not been established. Chronic studies in rats, dogs, and monkeys at dosages greater than 30 mg/kg/day showed growth or weight depression and signs of hepatopathy and possible occlusion nephropathy, all of which were reversible upon cessation of treatment. Sprague-Dawley female rats fed dantrolene sodium for 18 months at dosage levels of 15, 30, and 60 mg/kg/day showed an increased incidence of benign and malignant mammary tumors compared with concurrent controls.At the highest dose level, there was an increase in the incidence of benign lymphatic neoplasms. In a 30-month study at the same dose levels also in Sprague-Dawley rats, dantrolene sodium produced a decrease in the time of onset of mammary neoplasms. Female rats at the highest dose level showed an increased incidence of hepatic lymphangiomas and hepatic angiosarcomas. The only drug-related effect seen in a 30-month study in Fischer-344 rats was a dose-related reduction in the time of onset of mammary and testicular tumors. A 24-month study in HaM/ICR mice revealed no evidence of carcinogenic activity. Carcinogenicity in humans cannot be fully excluded, so that this possible risk of chronic administration must be weighed against the benefits of the drug (i.e., after a brief trial) for the individual patient. Dantrolene sodium has produced positive results in the Ames S. Typhimurium bacterial mutagenesis assay in the presence and absence of a liver activating system. Pregnancy: Pregnancy Category C: Pregnancy Category C: Adequate animal reproduction studies have not been conducted with Dantrium. It is also not known whether Dantrium can cause fetal harm when administered to a pregnant woman or can affect reproduction capacity. Dantrium should be given to a pregnant woman only if clearly needed. Labor and Delivery: In one non-randomized open-label study, 21 term pregnant patients received prophylactic oral Dantrium 100 mg per day for 2 to 10 days prior to delivery. Dantrolene readily crossed the placenta with maternal and fetal whole blood levels approximately equal at delivery; neonatal levels then fell approximately 50% per day for 2 days before declining sharply. No neonatal respiratory and neuromuscular side effects were detected Reference ID: 3100954 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda NDA 17443/S-/S-043/S-046/S-048/S-049 Page 11 at low dose. More data, at higher doses, are needed before more definitive conclusions can be made. Nursing Mothers: Dantrium should not be used in nursing mothers. Usage in Pediatric Patients: The long-term safety of Dantrium in pediatric patients under the age of 5 years has not been established. Because of the possibility that adverse effects of the drug could become apparent only after many years, a benefit-risk consideration of the long-term use of Dantrium is particularly important in pediatric patients. Geriatric Use: Clinical studies of Dantrium did not include sufficient numbers of subjects aged 65 and over to determine whether they respond differently from younger subjects. Other reported clinical experience in the literature has not identified differences in responses between the elderly and younger patients. In general, dose selection for an elderly patient should be cautious, reflecting the greater frequency of decreased hepatic, renal, or cardiac function, and of concomitant disease or other drug therapy. As with all patients receiving Dantrium, it is recommended that elderly patients receive the lowest dose compatible with the optimal response. Spontaneous reports suggest a higher proportion of hepatic events with fatal outcome in elderly patients receiving Dantrium. However, the majority of these cases were complicated with confounding factors such as intercurrent illnesses and/or concomitant potentially hepatotoxic medications (for hepatotoxicity details and its management see Black Box and Warnings Sections). Drug Interactions: Drowsiness may occur with Dantrium therapy, and the concomitant administration of CNS depressants such as sedatives and tranquilizing agents may result in further drowsiness. While a definite drug interaction with estrogen therapy has not yet been established, caution should be observed if the two drugs are to be given concomitantly. Hepatotoxicity has occurred more often in women over 35 years of age receiving concomitant estrogen therapy. Cardiovascular collapse in patients treated simultaneously with verapamil and dantrolene sodium is rare. The combination of therapeutic doses of intravenous dantrolene sodium and verapamil in halothane/-chloralose anesthetized swine has resulted in ventricular fibrillation and cardiovascular collapse in association with marked hyperkalemia. Until the relevance of these findings to humans is established, the combination of dantrolene sodium and calcium channel blockers is not recommended during the management of malignant hyperthermia. Administration of Dantrium may potentiate vecuronium-induced neuromuscular block. PRECAUTIONS Dantrium should be used with caution in patients with impaired pulmonary function, particularly those with obstructive pulmonary disease, and in patients with severely impaired cardiac function due to myocardial disease. Dantrium is associated with pleural effusion with associated eosinophilia. It should be used with caution in patients with a history of previous liver disease or dysfunction (see WARNINGS).

For current labeling information, please visit https://www.fda.gov/drugsatfda NDA 17443/S-/S-043/S-046/S-048/S-049 Page 12 Information for Patients: Patients should be cautioned against driving a motor vehicle or participating in hazardous occupations while taking Dantrium. Caution should be exercised in the concomitant administration of tranquilizing agents. Dantrium might possibly evoke a photosensitivity reaction; patients should be cautioned about exposure to sunlight while taking it. ADVERSE REACTIONS The most frequently occurring side effects of Dantrium have been drowsiness, dizziness, weakness, general malaise, fatigue, and diarrhea. These are generally transient, occurring early in treatment, and can often be obviated by beginning with a low dose and increasing dosage gradually until an optimal regimen is established. Diarrhea may be severe and may necessitate temporary withdrawal of Dantrium therapy. If diarrhea recurs upon readministration of Dantrium, therapy should probably be withdrawn permanently. Other less frequent side effects, listed according to system, are: Gastrointestinal: Constipation, rarely progressing to signs of intestinal obstruction, GI bleeding, anorexia, swallowing difficulty, gastric irritation, abdominal cramps, nausea and/or vomiting. Hepatobiliary: Hepatitis (see WARNINGS). Neurologic: Speech disturbance, seizure, headache, light-headedness, visual disturbance, diplopia, alteration of taste, insomnia, drooling. Cardiovascular: Tachycardia, erratic blood pressure, phlebitis, heart failure. Hematologic: Aplastic anemia, anemia, leukopenia, lymphocytic lymphoma, thrombocytopenia. Psychiatric: Mental depression, mental confusion, increased nervousness. Urogenital: Increased urinary frequency, crystalluria, hematuria, difficult erection, urinary incontinence and/or nocturia, difficult urination and/or urinary retention. Integumentary: Abnormal hair growth, acne-like rash, pruritus, urticaria, eczematoid eruption, sweating. Musculoskeletal: Myalgia, backache. Respiratory: Feeling of suffocation, respiratory depression. Special Senses: Excessive tearing. Hypersensitivity: Pleural effusion with pericarditis, pleural effusion with associated eosinophilia, anaphylaxis. Other: Chills and fever.

To report SUSPECTED ADVERSE REACTIONS, contact JHP at 1-866-923-2547 or MEDWATCH at 1­ 800-FDA-1088 (1-800-332-1088) or http://www.fda.gov/medwatch/. DRUG ABUSE AND DEPENDENCE Drug abuse and dependency potential has not been evaluated in human or animal studies. OVERDOSAGE Symptoms which may occur in case of overdose include, but are not limited to, muscular weakness and alterations in the state of consciousness (e.g. lethargy, coma), vomiting, diarrhea, and crystalluria. For acute overdose, general supportive measures should be employed along with immediate gastric lavage. Intravenous fluids should be administered in fairly large quantities to avert the possibility of crystalluria. An adequate airway should be maintained and artificial resuscitation equipment should be at hand. Electrocardiographic monitoring should be instituted, and the patient carefully observed. To date, no experience has been reported with dialysis and its value in Dantrium overdose is not known. DOSAGE AND ADMINISTRATION For Use in Chronic Spasticity: Prior to the administration of Dantrium, consideration should be given to the potential response to treatment. A decrease in spasticity sufficient to allow a daily function not otherwise attainable should be the therapeutic goal of treatment with Dantrium. Refer to INDICATIONS AND USAGE section for description of response to be anticipated. It is important to establish a therapeutic goal (regain and maintain a specific function such as therapeutic exercise program, utilization of braces, transfer maneuvers, etc.) before beginning Dantrium therapy. Dosage should be increased until the maximum performance compatible with the dysfunction due to underlying disease is achieved. No further increase in dosage is then indicated. Usual Dosage: It is important that the dosage be titrated and individualized for maximum effect. The lowest dose compatible with optimal response is recommended. In view of the potential for liver damage in long-term Dantrium use, therapy should be stopped if benefits are not evident within 45 days. Adults: The following gradual titration schedule is suggested. Some patients will not respond until higher daily dosage is achieved. Each dosage level should be maintained for seven days to determine the patient’s response. If no further benefit is observed at the next higher dose, dosage should be decreased to the previous lower dose. Reference ID: 3100954 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda NDA 17443/S-/S-043/S-046/S-048/S-049 Page 14 25 mg once daily for seven days, then 25 mg t.i.d. for seven days 50 mg t.i.d. for seven days 100 mg t.i.d. Therapy with a dose four times daily may be necessary for some individuals. Doses higher than 100 mg four times daily should not be used. (See Box Warning.) Pediatric Patients: The following gradual titration schedule is suggested. Some patients will not respond until higher daily dosage is achieved. Each dosage level should be maintained for seven days to determine the patient’s response. If no further benefit is observed at the next higher dose, dosage should be decreased to the previous lower dose. 0.5 mg/kg once daily for seven days, then 0.5 mg/kg t.i.d. for seven days 1 mg/kg t.i.d. for seven days 2 mg/kg t.i.d. Therapy with a dose four times daily may be necessary for some individuals. Doses higher than 100 mg four times daily should not be used. (See Box Warning.) For Malignant Hyperthermia: Preoperatively: Administer 4 to 8 mg/kg/day of oral Dantrium in 3 or 4 divided doses for one or two days prior to surgery, with the last dose being given approximately 3 to 4 hours before scheduled surgery with a minimum of water. This dosage will usually be associated with skeletal muscle weakness and sedation (sleepiness or drowsiness); adjustment can usually be made within the recommended dosage range to avoid incapacitation or excessive gastrointestinal irritation (including nausea and/or vomiting). Post Crisis Follow-up: Oral Dantrium should also be administered following a malignant hyperthermia crisis, in doses of 4 to 8 mg/kg per day in four divided doses, for a one to three day period to prevent recurrence of the manifestations of malignant hyperthermia.

Minipress® Capsules (prazosin hydrochloride) For Oral Use DESCRIPTION MINIPRESS® (prazosin hydrochloride), a quinazoline derivative, is the first of a new chemical class of antihypertensives. It is the hydrochloride salt of 1-(4-amino-6,7-dimethoxy­ 2-quinazolinyl)-4-(2-furoyl) piperazine and its structural formula is: s tr uc tura l form ula Molecular formula C19H21N5O4HCl It is a white, crystalline substance, slightly soluble in water and isotonic saline, and has a molecular weight of 419.87. Each 1 mg capsule of MINIPRESS for oral use contains drug equivalent to 1 mg free base. Inert ingredients in the formulations are: hard gelatin capsules (which may contain Blue 1, Red 3, Red 28, Red 40, and other inert ingredients); magnesium stearate; sodium lauryl sulfate; starch; sucrose. CLINICAL PHARMACOLOGY The exact mechanism of the hypotensive action of prazosin is unknown. Prazosin causes a decrease in total peripheral resistance and was originally thought to have a direct relaxant action on vascular smooth muscle. Recent animal studies, however, have suggested that the vasodilator effect of prazosin is also related to blockade of postsynaptic alpha-adrenoceptors. The results of dog forelimb experiments demonstrate that the peripheral vasodilator effect of prazosin is 1 Reference ID: 3708942 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda confined mainly to the level of the resistance vessels (arterioles). Unlike conventional alpha-blockers, the antihypertensive action of prazosin is usually not accompanied by a reflex tachycardia. Tolerance has not been observed to develop in long term therapy. Hemodynamic studies have been carried out in man following acute single dose administration and during the course of long term maintenance therapy. The results confirm that the therapeutic effect is a fall in blood pressure unaccompanied by a clinically significant change in cardiac output, heart rate, renal blood flow and glomerular filtration rate. There is no measurable negative chronotropic effect. In clinical studies to date, prazosin hydrochloride has not increased plasma renin activity. In man, blood pressure is lowered in both the supine and standing positions. This effect is most pronounced on the diastolic blood pressure. Following oral administration, human plasma concentrations reach a peak at about three hours with a plasma half-life of two to three hours. The drug is highly bound to plasma protein. Bioavailability studies have demonstrated that the total absorption relative to the drug in a 20% alcoholic solution is 90%, resulting in peak levels approximately 65% of that of the drug in solution. Animal studies indicate that prazosin hydrochloride is extensively metabolized, primarily by demethylation and conjugation, and excreted mainly via bile and feces. Less extensive human studies suggest similar metabolism and excretion in man. In clinical studies in which lipid profiles were followed, there were generally no adverse changes noted between pre- and post-treatment lipid levels. INDICATIONS AND USAGE MINIPRESS is indicated for the treatment of hypertension, to lower blood pressure. Lowering blood pressure reduces the risk of fatal and nonfatal cardiovascular events, primarily strokes and myocardial infarctions. These benefits have been seen in controlled trials of antihypertensive drugs from a wide variety of pharmacologic classes, including this drug. Control of high blood pressure should be part of comprehensive cardiovascular risk management, including, as appropriate, lipid control, diabetes management, antithrombotic therapy, smoking cessation, exercise, and limited sodium intake. Many patients will require more than one drug to achieve blood pressure goals. For specific advice on goals and management, see published guidelines, such as those of the National High Blood Pressure Education Program’s Joint National Committee on Prevention, Detection, Evaluation, and Treatment of High Blood Pressure (JNC). Numerous antihypertensive drugs, from a variety of pharmacologic classes and with different mechanisms of action, have been shown in randomized controlled trials to reduce cardiovascular morbidity and mortality, and it can be concluded that it is blood pressure reduction, and not some other pharmacologic property of the drugs, that is largely responsible for those benefits. The 2 Reference ID: 3708942 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda largest and most consistent cardiovascular outcome benefit has been a reduction in the risk of stroke, but reductions in myocardial infarction and cardiovascular mortality also have been seen regularly. Elevated systolic or diastolic pressure causes increased cardiovascular risk, and the absolute risk increase per mmHg is greater at higher blood pressures, so that even modest reductions of severe hypertension can provide substantial benefit. Relative risk reduction from blood pressure reduction is similar across populations with varying absolute risk, so the absolute benefit is greater in patients who are at higher risk independent of their hypertension (for example, patients with diabetes or hyperlipidemia), and such patients would be expected to benefit from more aggressive treatment to a lower blood pressure goal. Some antihypertensive drugs have smaller blood pressure effects (as monotherapy) in black patients, and many antihypertensive drugs have additional approved indications and effects (e.g., on angina, heart failure, or diabetic kidney disease). These considerations may guide selection of therapy. MINIPRESS can be used alone or in combination with other antihypertensive drugs such as diuretics or beta-adrenergic blocking agents. CONTRAINDICATIONS MINIPRESS is contraindicated in patients with known sensitivity to quinazolines, prazosin, or any of the inert ingredients. WARNINGS As with all alpha-blockers, MINIPRESS may cause syncope with sudden loss of consciousness. In most cases, this is believed to be due to an excessive postural hypotensive effect, although occasionally the syncopal episode has been preceded by a bout of severe tachycardia with heart rates of 120–160 beats per minute. Syncopal episodes have usually occurred within 30 to 90 minutes of the initial dose of the drug; occasionally, they have been reported in association with rapid dosage increases or the introduction of another antihypertensive drug into the regimen of a patient taking high doses of MINIPRESS. The incidence of syncopal episodes is approximately 1% in patients given an initial dose of 2 mg or greater. Clinical trials conducted during the investigational phase of this drug suggest that syncopal episodes can be minimized by limiting the initial dose of the drug to 1 mg, by subsequently increasing the dosage slowly, and by introducing any additional antihypertensive drugs into the patient’s regimen with caution (see DOSAGE AND ADMINISTRATION). Hypotension may develop in patients given MINIPRESS who are also receiving a beta-blocker such as propranolol. If syncope occurs, the patient should be placed in the recumbent position and treated supportively as necessary. This adverse effect is self-limiting and in most cases does not recur after the initial period of therapy or during subsequent dose titration. 3 Reference ID: 3708942 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda Patients should always be started on the 1 mg capsules of MINIPRESS. The 2 and 5 mg capsules are not indicated for initial therapy. More common than loss of consciousness are the symptoms often associated with lowering of the blood pressure, namely, dizziness and lightheadedness. The patient should be cautioned about these possible adverse effects and advised what measures to take should they develop. The patient should also be cautioned to avoid situations where injury could result should syncope occur during the initiation of MINIPRESS therapy. Priapism Prolonged erections and priapism have been reported with alpha-1 blockers including prazosin in post marketing experience. In the event of an erection that persists longer than 4 hours, seek immediate medical assistance. If priapism is not treated immediately, penile tissue damage and permanent loss of potency could result. PRECAUTIONS General Intraoperative Floppy Iris Syndrome (IFIS) has been observed during cataract surgery in some patients treated with alpha-1 blockers. This variant of small pupil syndrome is characterized by the combination of a flaccid iris that billows in response to intraoperative irrigation currents, progressive intraoperative miosis despite preoperative dilation with standard mydriatic drugs, and potential prolapse of the iris toward the phacoemulsification incisions. The patient’s ophthalmologist should be prepared for possible modifications to the surgical technique, such as the utilization of iris hooks, iris dilator rings, or viscoelastic substances. There does not appear to be a benefit of stopping alpha-1 blocker therapy prior to cataract surgery. Information for Patients: Dizziness or drowsiness may occur after the first dose of this medicine. Avoid driving or performing hazardous tasks for the first 24 hours after taking this medicine or when the dose is increased. Dizziness, lightheadedness, or fainting may occur, especially when rising from a lying or sitting position. Getting up slowly may help lessen the problem. These effects may also occur if you drink alcohol, stand for long periods of time, exercise, or if the weather is hot. While taking MINIPRESS, be careful in the amount of alcohol you drink. Also, use extra care during exercise or hot weather, or if standing for long periods. Check with your physician if you have any questions. Drug Interactions MINIPRESS has been administered without any adverse drug interaction in limited clinical experience to date with the following: (1) cardiac glycosides– digitalis and digoxin; (2) hypoglycemics–insulin, chlorpropamide, phenformin, tolazamide, and tolbutamide; (3) tranquilizers and sedatives–chlordiazepoxide, diazepam, and phenobarbital; (4) antigout– allopurinol, colchicine, and probenecid; (5) antiarrhythmics–procainamide, propranolol (see WARNINGS however), and quinidine; and (6) analgesics, antipyretics and anti-inflammatories– propoxyphene, aspirin, indomethacin, and phenylbutazone. 4 Reference ID: 3708942 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda Addition of a diuretic or other antihypertensive agent to MINIPRESS has been shown to cause an additive hypotensive effect. This effect can be minimized by reducing the MINIPRESS dose to 1 to 2 mg three times a day, by introducing additional antihypertensive drugs cautiously, and then by retitrating MINIPRESS based on clinical response. Concomitant administration of MINIPRESS with a phosphodiesterase-5 (PDE-5) inhibitor can result in additive blood pressure lowering effects and symptomatic hypotension (see DOSAGE AND ADMINISTRATION). Drug/Laboratory Test Interactions In a study on five patients given from 12 to 24 mg of prazosin per day for 10 to 14 days, there was an average increase of 42% in the urinary metabolite of norepinephrine and an average increase in urinary VMA of 17%. Therefore, false positive results may occur in screening tests for pheochromocytoma in patients who are being treated with prazosin. If an elevated VMA is found, prazosin should be discontinued and the patient retested after a month. Laboratory Tests In clinical studies in which lipid profiles were followed, there were generally no adverse changes noted between pre- and post-treatment lipid levels. Carcinogenesis, Mutagenesis, Impairment of Fertility: No carcinogenic potential was demonstrated in an 18 month study in rats with MINIPRESS at dose levels more than 225 times the usual maximum recommended human dose of 20 mg per day. MINIPRESS was not mutagenic in in vivo genetic toxicology studies. In a fertility and general reproductive performance study in rats, both males and females, treated with 75 mg/kg (225 times the usual maximum recommended human dose), demonstrated decreased fertility, while those treated with 25 mg/kg (75 times the usual maximum recommended human dose) did not. In chronic studies (one year or more) of MINIPRESS in rats and dogs, testicular changes consisting of atrophy and necrosis occurred at 25 mg/kg/day (75 times the usual maximum recommended human dose). No testicular changes were seen in rats or dogs at 10 mg/kg/day (30 times the usual maximum recommended human dose). In view of the testicular changes observed in animals, 105 patients on long term MINIPRESS therapy were monitored for 17-ketosteroid excretion and no changes indicating a drug effect were observed. In addition, 27 males on MINIPRESS for up to 51 months did not have changes in sperm morphology suggestive of drug effect. 5 Reference ID: 3708942 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda Usage in Pregnancy: Pregnancy Category C. MINIPRESS has been shown to be associated with decreased litter size at birth, 1, 4, and 21 days of age in rats when given doses more than 225 times the usual maximum recommended human dose. No evidence of drug-related external, visceral, or skeletal fetal abnormalities were observed. No drug-related external, visceral, or skeletal abnormalities were observed in fetuses of pregnant rabbits and pregnant monkeys at doses more than 225 times and 12 times the usual maximum recommended human dose, respectively. The use of prazosin and a beta-blocker for the control of severe hypertension in 44 pregnant women revealed no drug-related fetal abnormalities or adverse effects. Therapy with prazosin was continued for as long as 14 weeks.1 Prazosin has also been used alone or in combination with other hypotensive agents in severe hypertension of pregnancy by other investigators. No fetal or neonatal abnormalities have been reported with the use of prazosin.2 There are no adequate and well controlled studies which establish the safety of MINIPRESS in pregnant women. MINIPRESS should be used during pregnancy only if the potential benefit justifies the potential risk to the mother and fetus. Nursing Mothers: MINIPRESS has been shown to be excreted in small amounts in human milk. Caution should be exercised when MINIPRESS is administered to a nursing woman. Usage in Children: Safety and effectiveness in children have not been established. ADVERSE REACTIONS Clinical trials were conducted on more than 900 patients. During these trials and subsequent marketing experience, the most frequent reactions associated with MINIPRESS therapy are: dizziness 10.3%, headache 7.8%, drowsiness 7.6%, lack of energy 6.9%, weakness 6.5%, palpitations 5.3%, and nausea 4.9%. In most instances, side effects have disappeared with continued therapy or have been tolerated with no decrease in dose of drug. Less frequent adverse reactions which are reported to occur in 1–4% of patients are: Gastrointestinal: vomiting, diarrhea, constipation. Cardiovascular: edema, orthostatic hypotension, dyspnea, syncope. Central Nervous System: vertigo, depression, nervousness. Dermatologic: rash. 6 Reference ID: 3708942 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda Genitourinary: urinary frequency. EENT: blurred vision, reddened sclera, epistaxis, dry mouth, nasal congestion. In addition, fewer than 1% of patients have reported the following (in some instances, exact causal relationships have not been established): Gastrointestinal: abdominal discomfort and/or pain, liver function abnormalities, pancreatitis. Cardiovascular: tachycardia. Central Nervous System: paresthesia, hallucinations. Dermatologic: pruritus, alopecia, lichen planus. Genitourinary: incontinence, impotence, priapism. EENT: tinnitus. Other: diaphoresis, fever, positive ANA titer, arthralgia. Single reports of pigmentary mottling and serous retinopathy, and a few reports of cataract development or disappearance have been reported. In these instances, the exact causal relationship has not been established because the baseline observations were frequently inadequate. In more specific slit-lamp and funduscopic studies, which included adequate baseline examinations, no drug-related abnormal ophthalmological findings have been reported. Literature reports exist associating MINIPRESS therapy with a worsening of pre-existing narcolepsy. A causal relationship is uncertain in these cases. In post-marketing experience, the following adverse events have been reported: Autonomic Nervous System: flushing. Body As A Whole: allergic reaction, asthenia, malaise, pain. Cardiovascular, General: angina pectoris, hypotension. Endocrine: gynecomastia. Heart Rate/Rhythm: bradycardia. Psychiatric: insomnia. 7 Reference ID: 3708942 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda Skin/Appendages: urticaria. Vascular (Extracardiac): vasculitis. Vision: eye pain. Special Senses: During cataract surgery, a variant of small pupil syndrome known as Intraoperative Floppy Iris Syndrome (IFIS) has been reported in association with alpha-1 blocker therapy (see PRECAUTIONS). OVERDOSAGE Accidental ingestion of at least 50 mg of MINIPRESS in a two year old child resulted in profound drowsiness and depressed reflexes. No decrease in blood pressure was noted. Recovery was uneventful. Should overdosage lead to hypotension, support of the cardiovascular system is of first importance. Restoration of blood pressure and normalization of heart rate may be accomplished by keeping the patient in the supine position. If this measure is inadequate, shock should first be treated with volume expanders. If necessary, vasopressors should then be used. Renal function should be monitored and supported as needed. Laboratory data indicate MINIPRESS is not dialysable because it is protein bound. DOSAGE AND ADMINISTRATION The dose of MINIPRESS should be adjusted according to the patient’s individual blood pressure response. The following is a guide to its administration: Initial Dose 1 mg two or three times a day (see WARNINGS.) Maintenance Dose Dosage may be slowly increased to a total daily dose of 20 mg given in divided doses. The therapeutic dosages most commonly employed have ranged from 6 mg to 15 mg daily given in divided doses. Doses higher than 20 mg usually do not increase efficacy, however a few patients may benefit from further increases up to a daily dose of 40 mg given in divided doses. After initial titration some patients can be maintained adequately on a twice daily dosage regimen. 8 Reference ID: 3708942 This label may not be the latest approved by FDA.

NDA 17443/S-/S-043/S-046/S-048/S-049 Page 7 Dantrium (dantrolene sodium) capsules Dantrium (dantrolene sodium) has a potential for hepatotoxicity, and should not be used in conditions other than those recommended. Symptomatic hepatitis (fatal and non­ fatal) has been reported at various dose levels of the drug. The incidence reported in patients taking up to 400 mg/day is much lower than in those taking doses of 800 mg or more per day. Even sporadic short courses of these higher dose levels within a treatment regimen markedly increased the risk of serious hepatic injury. Liver dysfunction as evidenced by blood chemical abnormalities alone (liver enzyme elevations) has been observed in patients exposed to Dantrium for varying periods of time. Overt hepatitis has occurred at varying intervals after initiation of therapy, but has been most frequently observed between the third and twelfth month of therapy. The risk of hepatic injury appears to be greater in females, in patients over 35 years of age, and in patients taking other medication(s) in addition to Dantrium (dantrolene sodium). Spontaneous reports suggest a higher proportion of hepatic events with fatal outcome in elderly patients receiving Dantrium. However, the majority of these cases were complicated with confounding factors such as intercurrent illnesses and/or concomitant potentially hepatotoxic medications (see Geriatric Use subsection). Dantrium should be used only in conjunction with appropriate monitoring of hepatic function including frequent determination of SGOT or SGPT. If no observable benefit is derived from the administration of Dantrium after a total of 45 days, therapy should be discontinued. The lowest possible effective dose for the individual patient should be prescribed. DESCRIPTION The chemical formula of Dantrium (dantrolene sodium) is hydrated 1-[[[5-(4-nitrophenyl)-2­ furanyl]methylene]amino]-2, 4-imidazolidinedione sodium salt. It is an orange powder, slightly soluble in water, but due to its slightly acidic nature the solubility increases somewhat in alkaline solution. The anhydrous salt has a molecular weight of 336. The hydrated salt contains approximately 15% water (3-1/2 moles) and has a molecular weight of 399. The structural formula for the hydrated salt is: stru ctu ra l fo rmula Dantrium is supplied in capsules of 25 mg, 50 mg, and 100 mg. Inactive Ingredients: Each capsule contains edible black ink, FD&C Yellow No.6, gelatin, lactose, magnesium stearate, starch, synthetic iron oxide red, synthetic iron oxide yellow, talc and titanium dioxide., CLINICAL PHARMACOLOGY In isolated nerve-muscle preparation, Dantrium has been shown to produce relaxation by affecting the contractile response of the skeletal muscle at a site beyond the myoneural junction, directly on the muscle itself. In skeletal muscle, Dantrium dissociates the excitation-contraction coupling, probably by interfering with the release of Ca++ from the sarcoplasmic reticulum. This effect appears to be more pronounced in fast muscle fibers as compared to slow ones, but Reference ID: 3100954 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda NDA 17443/S-/S-043/S-046/S-048/S-049 Page 8 generally affects both. A central nervous system effect occurs, with drowsiness, dizziness, and generalized weakness occasionally present. Although Dantrium does not appear to directly affect the CNS, the extent of its indirect effect is unknown. The absorption of Dantrium after oral administration in humans is incomplete and slow but consistent, and dose-related blood levels are obtained. The duration and intensity of skeletal muscle relaxation is related to the dosage and blood levels. The mean biologic half-life of Dantrium in adults is 8.7 hours after a 100-mg dose. Specific metabolic pathways in the degradation and elimination of Dantrium in human subjects have been established. Metabolic patterns are similar in adults and pediatric patients. In addition to the parent compound, dantrolene, which is found in measurable amounts in blood and urine, the major metabolites noted in body fluids are the 5-hydroxy analog and the acetamido analog. Since Dantrium is probably metabolized by hepatic microsomal enzymes, enhancement of its metabolism by other drugs is possible. However, neither phenobarbital nor diazepam appears to affect Dantrium metabolism. Clinical experience in the management of fulminant human malignant hyperthermia, as well as experiments conducted in malignant hyperthermia susceptible swine, have revealed that the administration of intravenous dantrolene, combined with indicated supportive measures, is effective in reversing the hypermetabolic process of malignant hyperthermia. Known differences between human and swine malignant hyperthermia are minor. The prophylactic administration of oral or intravenous dantrolene to malignant hyperthermia susceptible swine will attenuate or prevent the development of signs of malignant hyperthermia in a manner dependent upon the dosage of dantrolene administered and the intensity of the malignant hyperthermia triggering stimulus. Limited clinical experience with the administration of oral dantrolene to patients judged malignant hyperthermia susceptible, when combined with clinical experience in the use of intravenous dantrolene for the treatment of malignant hyperthermia and data derived from the above cited animal model experiments, suggests that oral dantrolene will also attenuate or prevent the development of signs of human malignant hyperthermia, provided that currently accepted practices in the management of such patients are adhered to (see INDICATIONS AND USAGE); intravenous dantrolene should also be available for use should the signs of malignant hyperthermia appear. INDICATIONS AND USAGE In Chronic Spasticity: Dantrium is indicated in controlling the manifestations of clinical spasticity resulting from upper motor neuron disorders (e.g., spinal cord injury, stroke, cerebral palsy, or multiple sclerosis). It is of particular benefit to the patient whose functional rehabilitation has been retarded by the sequelae of spasticity. Such patients must have presumably reversible spasticity where relief of spasticity will aid in restoring residual function. Dantrium is not indicated in the treatment of skeletal muscle spasm resulting from rheumatic disorders. If improvement occurs, it will ordinarily occur within the dosage titration (see DOSAGE AND ADMINISTRATION), and will be manifested by a decrease in the severity of spasticity and the ability to resume a daily function not quite attainable without Dantrium. Occasionally, subtle but meaningful improvement in spasticity may occur with Dantrium therapy. In such instances, information regarding improvement should be solicited from the patient and those who are in constant daily contact and attendance with him. Brief withdrawal of Dantrium for a period of 2 to 4 days will frequently demonstrate exacerbation of the manifestations of spasticity and may serve to confirm a clinical impression. Reference ID: 3100954 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda NDA 17443/S-/S-043/S-046/S-048/S-049 Page 9 A decision to continue the administration of Dantrium on a long-term basis is justified if introduction of the drug into the patient's regimen: produces a significant reduction in painful and/or disabling spasticity such as clonus, or permits a significant reduction in the intensity and/or degree of nursing care required, or rids the patient of any annoying manifestation of spasticity considered important by the patient himself. In Malignant Hyperthermia: Oral Dantrium is also indicated preoperatively to prevent or attenuate the development of signs of malignant hyperthermia in known, or strongly suspect, malignant hyperthermia susceptible patients who require anesthesia and/or surgery. Currently accepted clinical practices in the management of such patients must still be adhered to (careful monitoring for early signs of malignant hyperthermia, minimizing exposure to triggering mechanisms and prompt use of intravenous dantrolene sodium and indicated supportive measures should signs of malignant hyperthermia appear); see also the package insert for Dantrium® (dantrolene sodium) Intravenous. Oral Dantrium should be administered following a malignant hyperthermic crisis to prevent recurrence of the signs of malignant hyperthermia. CONTRAINDICATIONS Active hepatic disease, such as hepatitis and cirrhosis, is a contraindication for use of Dantrium. Dantrium is contraindicated where spasticity is utilized to sustain upright posture and balance in locomotion or whenever spasticity is utilized to obtain or maintain increased function. WARNINGS It is important to recognize that fatal and non-fatal liver disorders of an idiosyncratic or hypersensitivity type may occur with Dantrium therapy. At the start of Dantrium therapy, it is desirable to do liver function studies (SGOT, SGPT, alkaline phosphatase, total bilirubin) for a baseline or to establish whether there is pre-existing liver disease. If baseline liver abnormalities exist and are confirmed, there is a clear possibility that the potential for Dantrium hepatotoxicity could be enhanced, although such a possibility has not yet been established. Liver function studies (e.g., SGOT or SGPT) should be performed at appropriate intervals during Dantrium therapy. If such studies reveal abnormal values, therapy should generally be discontinued. Only where benefits of the drug have been of major importance to the patient, should reinitiation or continuation of therapy be considered. Some patients have revealed a return to normal laboratory values in the face of continued therapy while others have not. If symptoms compatible with hepatitis, accompanied by abnormalities in liver function tests or jaundice appear, Dantrium should be discontinued. If caused by Dantrium and detected early, the abnormalities in liver function characteristically have reverted to normal when the drug was discontinued. Reference ID: 3100954 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda NDA 17443/S-/S-043/S-046/S-048/S-049 Page 10 Dantrium therapy has been reinstituted in a few patients who have developed clinical and/or laboratory evidence of hepatocellular injury. If such reinstitution of therapy is done, it should be attempted only in patients who clearly need Dantrium and only after previous symptoms and laboratory abnormalities have cleared. The patient should be hospitalized and the drug should be restarted in very small and gradually increasing doses. Laboratory monitoring should be frequent and the drug should be withdrawn immediately if there is any indication of recurrent liver involvement. Some patients have reacted with unmistakable signs of liver abnormality upon administration of a challenge dose, while others have not. Dantrium should be used with particular caution in females and in patients over 35 years of age in view of apparent greater likelihood of drug-induced, potentially fatal, hepatocellular disease in these groups. Spontaneous reports suggest a higher proportion of hepatic events with fatal outcome in elderly patients receiving Dantrium. However, the majority of these cases were complicated with confounding factors such as intercurrent illnesses and/or concomitant potentially hepatotoxic medications (see Geriatric Use subsection). Carcinogenesis, Mutagenesis, Impairment of Fertility: Long-term safety of Dantrium in humans has not been established. Chronic studies in rats, dogs, and monkeys at dosages greater than 30 mg/kg/day showed growth or weight depression and signs of hepatopathy and possible occlusion nephropathy, all of which were reversible upon cessation of treatment. Sprague-Dawley female rats fed dantrolene sodium for 18 months at dosage levels of 15, 30, and 60 mg/kg/day showed an increased incidence of benign and malignant mammary tumors compared with concurrent controls.At the highest dose level, there was an increase in the incidence of benign lymphatic neoplasms. In a 30-month study at the same dose levels also in Sprague-Dawley rats, dantrolene sodium produced a decrease in the time of onset of mammary neoplasms. Female rats at the highest dose level showed an increased incidence of hepatic lymphangiomas and hepatic angiosarcomas. The only drug-related effect seen in a 30-month study in Fischer-344 rats was a dose-related reduction in the time of onset of mammary and testicular tumors. A 24-month study in HaM/ICR mice revealed no evidence of carcinogenic activity. Carcinogenicity in humans cannot be fully excluded, so that this possible risk of chronic administration must be weighed against the benefits of the drug (i.e., after a brief trial) for the individual patient. Dantrolene sodium has produced positive results in the Ames S. Typhimurium bacterial mutagenesis assay in the presence and absence of a liver activating system. Pregnancy: Pregnancy Category C: Pregnancy Category C: Adequate animal reproduction studies have not been conducted with Dantrium. It is also not known whether Dantrium can cause fetal harm when administered to a pregnant woman or can affect reproduction capacity. Dantrium should be given to a pregnant woman only if clearly needed. Labor and Delivery: In one non-randomized open-label study, 21 term pregnant patients received prophylactic oral Dantrium 100 mg per day for 2 to 10 days prior to delivery. Dantrolene readily crossed the placenta with maternal and fetal whole blood levels approximately equal at delivery; neonatal levels then fell approximately 50% per day for 2 days before declining sharply. No neonatal respiratory and neuromuscular side effects were detected Reference ID: 3100954 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda NDA 17443/S-/S-043/S-046/S-048/S-049 Page 11 at low dose. More data, at higher doses, are needed before more definitive conclusions can be made. Nursing Mothers: Dantrium should not be used in nursing mothers. Usage in Pediatric Patients: The long-term safety of Dantrium in pediatric patients under the age of 5 years has not been established. Because of the possibility that adverse effects of the drug could become apparent only after many years, a benefit-risk consideration of the long-term use of Dantrium is particularly important in pediatric patients. Geriatric Use: Clinical studies of Dantrium did not include sufficient numbers of subjects aged 65 and over to determine whether they respond differently from younger subjects. Other reported clinical experience in the literature has not identified differences in responses between the elderly and younger patients. In general, dose selection for an elderly patient should be cautious, reflecting the greater frequency of decreased hepatic, renal, or cardiac function, and of concomitant disease or other drug therapy. As with all patients receiving Dantrium, it is recommended that elderly patients receive the lowest dose compatible with the optimal response. Spontaneous reports suggest a higher proportion of hepatic events with fatal outcome in elderly patients receiving Dantrium. However, the majority of these cases were complicated with confounding factors such as intercurrent illnesses and/or concomitant potentially hepatotoxic medications (for hepatotoxicity details and its management see Black Box and Warnings Sections). Drug Interactions: Drowsiness may occur with Dantrium therapy, and the concomitant administration of CNS depressants such as sedatives and tranquilizing agents may result in further drowsiness. While a definite drug interaction with estrogen therapy has not yet been established, caution should be observed if the two drugs are to be given concomitantly. Hepatotoxicity has occurred more often in women over 35 years of age receiving concomitant estrogen therapy. Cardiovascular collapse in patients treated simultaneously with verapamil and dantrolene sodium is rare. The combination of therapeutic doses of intravenous dantrolene sodium and verapamil in halothane/-chloralose anesthetized swine has resulted in ventricular fibrillation and cardiovascular collapse in association with marked hyperkalemia. Until the relevance of these findings to humans is established, the combination of dantrolene sodium and calcium channel blockers is not recommended during the management of malignant hyperthermia. Administration of Dantrium may potentiate vecuronium-induced neuromuscular block. PRECAUTIONS Dantrium should be used with caution in patients with impaired pulmonary function, particularly those with obstructive pulmonary disease, and in patients with severely impaired cardiac function due to myocardial disease. Dantrium is associated with pleural effusion with associated eosinophilia. It should be used with caution in patients with a history of previous liver disease or dysfunction (see WARNINGS).

For current labeling information, please visit https://www.fda.gov/drugsatfda NDA 17443/S-/S-043/S-046/S-048/S-049 Page 12 Information for Patients: Patients should be cautioned against driving a motor vehicle or participating in hazardous occupations while taking Dantrium. Caution should be exercised in the concomitant administration of tranquilizing agents. Dantrium might possibly evoke a photosensitivity reaction; patients should be cautioned about exposure to sunlight while taking it. ADVERSE REACTIONS The most frequently occurring side effects of Dantrium have been drowsiness, dizziness, weakness, general malaise, fatigue, and diarrhea. These are generally transient, occurring early in treatment, and can often be obviated by beginning with a low dose and increasing dosage gradually until an optimal regimen is established. Diarrhea may be severe and may necessitate temporary withdrawal of Dantrium therapy. If diarrhea recurs upon readministration of Dantrium, therapy should probably be withdrawn permanently. Other less frequent side effects, listed according to system, are: Gastrointestinal: Constipation, rarely progressing to signs of intestinal obstruction, GI bleeding, anorexia, swallowing difficulty, gastric irritation, abdominal cramps, nausea and/or vomiting. Hepatobiliary: Hepatitis (see WARNINGS). Neurologic: Speech disturbance, seizure, headache, light-headedness, visual disturbance, diplopia, alteration of taste, insomnia, drooling. Cardiovascular: Tachycardia, erratic blood pressure, phlebitis, heart failure. Hematologic: Aplastic anemia, anemia, leukopenia, lymphocytic lymphoma, thrombocytopenia. Psychiatric: Mental depression, mental confusion, increased nervousness. Urogenital: Increased urinary frequency, crystalluria, hematuria, difficult erection, urinary incontinence and/or nocturia, difficult urination and/or urinary retention. Integumentary: Abnormal hair growth, acne-like rash, pruritus, urticaria, eczematoid eruption, sweating. Musculoskeletal: Myalgia, backache. Respiratory: Feeling of suffocation, respiratory depression. Special Senses: Excessive tearing. Hypersensitivity: Pleural effusion with pericarditis, pleural effusion with associated eosinophilia, anaphylaxis. Other: Chills and fever.

DRUG ABUSE AND DEPENDENCE Drug abuse and dependency potential has not been evaluated in human or animal studies. OVERDOSAGE Symptoms which may occur in case of overdose include, but are not limited to, muscular weakness and alterations in the state of consciousness (e.g. lethargy, coma), vomiting, diarrhea, and crystalluria. For acute overdose, general supportive measures should be employed along with immediate gastric lavage. Intravenous fluids should be administered in fairly large quantities to avert the possibility of crystalluria. An adequate airway should be maintained and artificial resuscitation equipment should be at hand. Electrocardiographic monitoring should be instituted, and the patient carefully observed. To date, no experience has been reported with dialysis and its value in Dantrium overdose is not known. DOSAGE AND ADMINISTRATION For Use in Chronic Spasticity: Prior to the administration of Dantrium, consideration should be given to the potential response to treatment. A decrease in spasticity sufficient to allow a daily function not otherwise attainable should be the therapeutic goal of treatment with Dantrium. Refer to INDICATIONS AND USAGE section for description of response to be anticipated. It is important to establish a therapeutic goal (regain and maintain a specific function such as therapeutic exercise program, utilization of braces, transfer maneuvers, etc.) before beginning Dantrium therapy. Dosage should be increased until the maximum performance compatible with the dysfunction due to underlying disease is achieved. No further increase in dosage is then indicated. Usual Dosage: It is important that the dosage be titrated and individualized for maximum effect. The lowest dose compatible with optimal response is recommended. In view of the potential for liver damage in long-term Dantrium use, therapy should be stopped if benefits are not evident within 45 days. Adults: The following gradual titration schedule is suggested. Some patients will not respond until higher daily dosage is achieved. Each dosage level should be maintained for seven days to determine the patient’s response. If no further benefit is observed at the next higher dose, dosage should be decreased to the previous lower dose. Reference ID: 3100954 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda NDA 17443/S-/S-043/S-046/S-048/S-049 Page 14 25 mg once daily for seven days, then 25 mg t.i.d. for seven days 50 mg t.i.d. for seven days 100 mg t.i.d. Therapy with a dose four times daily may be necessary for some individuals. Doses higher than 100 mg four times daily should not be used. (See Box Warning.) Pediatric Patients: The following gradual titration schedule is suggested. Some patients will not respond until higher daily dosage is achieved. Each dosage level should be maintained for seven days to determine the patient’s response. If no further benefit is observed at the next higher dose, dosage should be decreased to the previous lower dose. 0.5 mg/kg once daily for seven days, then 0.5 mg/kg t.i.d. for seven days 1 mg/kg t.i.d. for seven days 2 mg/kg t.i.d. Therapy with a dose four times daily may be necessary for some individuals. Doses higher than 100 mg four times daily should not be used. (See Box Warning.) For Malignant Hyperthermia: Preoperatively: Administer 4 to 8 mg/kg/day of oral Dantrium in 3 or 4 divided doses for one or two days prior to surgery, with the last dose being given approximately 3 to 4 hours before scheduled surgery with a minimum of water. This dosage will usually be associated with skeletal muscle weakness and sedation (sleepiness or drowsiness); adjustment can usually be made within the recommended dosage range to avoid incapacitation or excessive gastrointestinal irritation (including nausea and/or vomiting). Post Crisis Follow-up: Oral Dantrium should also be administered following a malignant hyperthermia crisis, in doses of 4 to 8 mg/kg per day in four divided doses, for a one to three day period to prevent recurrence of the manifestations of malignant hyperthermia.

For current labeling information, please visit https://www.fda.gov/drugsatfda NDA 17443/S-/S-043/S-046/S-048/S-049 Page 9 A decision to continue the administration of Dantrium on a long-term basis is justified if introduction of the drug into the patient's regimen: produces a significant reduction in painful and/or disabling spasticity such as clonus, or permits a significant reduction in the intensity and/or degree of nursing care required, or rids the patient of any annoying manifestation of spasticity considered important by the patient himself. In Malignant Hyperthermia: Oral Dantrium is also indicated preoperatively to prevent or attenuate the development of signs of malignant hyperthermia in known, or strongly suspect, malignant hyperthermia susceptible patients who require anesthesia and/or surgery. Currently accepted clinical practices in the management of such patients must still be adhered to (careful monitoring for early signs of malignant hyperthermia, minimizing exposure to triggering mechanisms and prompt use of intravenous dantrolene sodium and indicated supportive measures should signs of malignant hyperthermia appear); see also the package insert for Dantrium® (dantrolene sodium) Intravenous. Oral Dantrium should be administered following a malignant hyperthermic crisis to prevent recurrence of the signs of malignant hyperthermia. CONTRAINDICATIONS Active hepatic disease, such as hepatitis and cirrhosis, is a contraindication for use of Dantrium. Dantrium is contraindicated where spasticity is utilized to sustain upright posture and balance in locomotion or whenever spasticity is utilized to obtain or maintain increased function. WARNINGS It is important to recognize that fatal and non-fatal liver disorders of an idiosyncratic or hypersensitivity type may occur with Dantrium therapy. At the start of Dantrium therapy, it is desirable to do liver function studies (SGOT, SGPT, alkaline phosphatase, total bilirubin) for a baseline or to establish whether there is pre-existing liver disease. If baseline liver abnormalities exist and are confirmed, there is a clear possibility that the potential for Dantrium hepatotoxicity could be enhanced, although such a possibility has not yet been established. Liver function studies (e.g., SGOT or SGPT) should be performed at appropriate intervals during Dantrium therapy. If such studies reveal abnormal values, therapy should generally be discontinued. Only where benefits of the drug have been of major importance to the patient, should reinitiation or continuation of therapy be considered. Some patients have revealed a return to normal laboratory values in the face of continued therapy while others have not. If symptoms compatible with hepatitis, accompanied by abnormalities in liver function tests or jaundice appear, Dantrium should be discontinued. If caused by Dantrium and detected early, the abnormalities in liver function characteristically have reverted to normal when the drug was discontinued.

For current labeling information, please visit https://www.fda.gov/drugsatfda NDA 17443/S-/S-043/S-046/S-048/S-049 Page 10 Dantrium therapy has been reinstituted in a few patients who have developed clinical and/or laboratory evidence of hepatocellular injury. If such reinstitution of therapy is done, it should be attempted only in patients who clearly need Dantrium and only after previous symptoms and laboratory abnormalities have cleared. The patient should be hospitalized and the drug should be restarted in very small and gradually increasing doses. Laboratory monitoring should be frequent and the drug should be withdrawn immediately if there is any indication of recurrent liver involvement. Some patients have reacted with unmistakable signs of liver abnormality upon administration of a challenge dose, while others have not. Dantrium should be used with particular caution in females and in patients over 35 years of age in view of apparent greater likelihood of drug-induced, potentially fatal, hepatocellular disease in these groups. Spontaneous reports suggest a higher proportion of hepatic events with fatal outcome in elderly patients receiving Dantrium. However, the majority of these cases were complicated with confounding factors such as intercurrent illnesses and/or concomitant potentially hepatotoxic medications (see Geriatric Use subsection). Carcinogenesis, Mutagenesis, Impairment of Fertility: Long-term safety of Dantrium in humans has not been established. Chronic studies in rats, dogs, and monkeys at dosages greater than 30 mg/kg/day showed growth or weight depression and signs of hepatopathy and possible occlusion nephropathy, all of which were reversible upon cessation of treatment. Sprague-Dawley female rats fed dantrolene sodium for 18 months at dosage levels of 15, 30, and 60 mg/kg/day showed an increased incidence of benign and malignant mammary tumors compared with concurrent controls.At the highest dose level, there was an increase in the incidence of benign lymphatic neoplasms. In a 30-month study at the same dose levels also in Sprague-Dawley rats, dantrolene sodium produced a decrease in the time of onset of mammary neoplasms. Female rats at the highest dose level showed an increased incidence of hepatic lymphangiomas and hepatic angiosarcomas. The only drug-related effect seen in a 30-month study in Fischer-344 rats was a dose-related reduction in the time of onset of mammary and testicular tumors. A 24-month study in HaM/ICR mice revealed no evidence of carcinogenic activity. Carcinogenicity in humans cannot be fully excluded, so that this possible risk of chronic administration must be weighed against the benefits of the drug (i.e., after a brief trial) for the individual patient. Dantrolene sodium has produced positive results in the Ames S. Typhimurium bacterial mutagenesis assay in the presence and absence of a liver activating system. Pregnancy: Pregnancy Category C: Pregnancy Category C: Adequate animal reproduction studies have not been conducted with Dantrium. It is also not known whether Dantrium can cause fetal harm when administered to a pregnant woman or can affect reproduction capacity. Dantrium should be given to a pregnant woman only if clearly needed. Labor and Delivery: In one non-randomized open-label study, 21 term pregnant patients received prophylactic oral Dantrium 100 mg per day for 2 to 10 days prior to delivery. Dantrolene readily crossed the placenta with maternal and fetal whole blood levels approximately equal at delivery; neonatal levels then fell approximately 50% per day for 2 days before declining sharply. No neonatal respiratory and neuromuscular side effects were detected Reference ID: 3100954 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda NDA 17443/S-/S-043/S-046/S-048/S-049 Page 11 at low dose. More data, at higher doses, are needed before more definitive conclusions can be made. Nursing Mothers: Dantrium should not be used in nursing mothers. Usage in Pediatric Patients: The long-term safety of Dantrium in pediatric patients under the age of 5 years has not been established. Because of the possibility that adverse effects of the drug could become apparent only after many years, a benefit-risk consideration of the long-term use of Dantrium is particularly important in pediatric patients. Geriatric Use: Clinical studies of Dantrium did not include sufficient numbers of subjects aged 65 and over to determine whether they respond differently from younger subjects. Other reported clinical experience in the literature has not identified differences in responses between the elderly and younger patients. In general, dose selection for an elderly patient should be cautious, reflecting the greater frequency of decreased hepatic, renal, or cardiac function, and of concomitant disease or other drug therapy. As with all patients receiving Dantrium, it is recommended that elderly patients receive the lowest dose compatible with the optimal response. Spontaneous reports suggest a higher proportion of hepatic events with fatal outcome in elderly patients receiving Dantrium. However, the majority of these cases were complicated with confounding factors such as intercurrent illnesses and/or concomitant potentially hepatotoxic medications (for hepatotoxicity details and its management see Black Box and Warnings Sections). Drug Interactions: Drowsiness may occur with Dantrium therapy, and the concomitant administration of CNS depressants such as sedatives and tranquilizing agents may result in further drowsiness. While a definite drug interaction with estrogen therapy has not yet been established, caution should be observed if the two drugs are to be given concomitantly. Hepatotoxicity has occurred more often in women over 35 years of age receiving concomitant estrogen therapy. Cardiovascular collapse in patients treated simultaneously with verapamil and dantrolene sodium is rare. The combination of therapeutic doses of intravenous dantrolene sodium and verapamil in halothane/-chloralose anesthetized swine has resulted in ventricular fibrillation and cardiovascular collapse in association with marked hyperkalemia. Until the relevance of these findings to humans is established, the combination of dantrolene sodium and calcium channel blockers is not recommended during the management of malignant hyperthermia. Administration of Dantrium may potentiate vecuronium-induced neuromuscular block. PRECAUTIONS Dantrium should be used with caution in patients with impaired pulmonary function, particularly those with obstructive pulmonary disease, and in patients with severely impaired cardiac function due to myocardial disease. Dantrium is associated with pleural effusion with associated eosinophilia. It should be used with caution in patients with a history of previous liver disease or dysfunction (see WARNINGS). Reference ID: 3100954 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda NDA 17443/S-/S-043/S-046/S-048/S-049 Page 12 Information for Patients: Patients should be cautioned against driving a motor vehicle or participating in hazardous occupations while taking Dantrium. Caution should be exercised in the concomitant administration of tranquilizing agents. Dantrium might possibly evoke a photosensitivity reaction; patients should be cautioned about exposure to sunlight while taking it. ADVERSE REACTIONS The most frequently occurring side effects of Dantrium have been drowsiness, dizziness, weakness, general malaise, fatigue, and diarrhea. These are generally transient, occurring early in treatment, and can often be obviated by beginning with a low dose and increasing dosage gradually until an optimal regimen is established. Diarrhea may be severe and may necessitate temporary withdrawal of Dantrium therapy. If diarrhea recurs upon readministration of Dantrium, therapy should probably be withdrawn permanently. Other less frequent side effects, listed according to system, are: Gastrointestinal: Constipation, rarely progressing to signs of intestinal obstruction, GI bleeding, anorexia, swallowing difficulty, gastric irritation, abdominal cramps, nausea and/or vomiting. Hepatobiliary: Hepatitis (see WARNINGS). Neurologic: Speech disturbance, seizure, headache, light-headedness, visual disturbance, diplopia, alteration of taste, insomnia, drooling. Cardiovascular: Tachycardia, erratic blood pressure, phlebitis, heart failure. Hematologic: Aplastic anemia, anemia, leukopenia, lymphocytic lymphoma, thrombocytopenia. Psychiatric: Mental depression, mental confusion, increased nervousness. Urogenital: Increased urinary frequency, crystalluria, hematuria, difficult erection, urinary incontinence and/or nocturia, difficult urination and/or urinary retention. Integumentary: Abnormal hair growth, acne-like rash, pruritus, urticaria, eczematoid eruption, sweating. Musculoskeletal: Myalgia, backache. Respiratory: Feeling of suffocation, respiratory depression. Special Senses: Excessive tearing. Hypersensitivity: Pleural effusion with pericarditis, pleural effusion with associated eosinophilia, anaphylaxis. Other: Chills and fever.

To report SUSPECTED ADVERSE REACTIONS, contact JHP at 1-866-923-2547 or MEDWATCH at 1­ 800-FDA-1088 (1-800-332-1088) or http://www.fda.gov/medwatch/. DRUG ABUSE AND DEPENDENCE Drug abuse and dependency potential has not been evaluated in human or animal studies. OVERDOSAGE Symptoms which may occur in case of overdose include, but are not limited to, muscular weakness and alterations in the state of consciousness (e.g. lethargy, coma), vomiting, diarrhea, and crystalluria. For acute overdose, general supportive measures should be employed along with immediate gastric lavage. Intravenous fluids should be administered in fairly large quantities to avert the possibility of crystalluria. An adequate airway should be maintained and artificial resuscitation equipment should be at hand. Electrocardiographic monitoring should be instituted, and the patient carefully observed. To date, no experience has been reported with dialysis and its value in Dantrium overdose is not known. DOSAGE AND ADMINISTRATION For Use in Chronic Spasticity: Prior to the administration of Dantrium, consideration should be given to the potential response to treatment. A decrease in spasticity sufficient to allow a daily function not otherwise attainable should be the therapeutic goal of treatment with Dantrium. Refer to INDICATIONS AND USAGE section for description of response to be anticipated. It is important to establish a therapeutic goal (regain and maintain a specific function such as therapeutic exercise program, utilization of braces, transfer maneuvers, etc.) before beginning Dantrium therapy. Dosage should be increased until the maximum performance compatible with the dysfunction due to underlying disease is achieved. No further increase in dosage is then indicated. Usual Dosage: It is important that the dosage be titrated and individualized for maximum effect. The lowest dose compatible with optimal response is recommended. In view of the potential for liver damage in long-term Dantrium use, therapy should be stopped if benefits are not evident within 45 days. Adults: The following gradual titration schedule is suggested. Some patients will not respond until higher daily dosage is achieved. Each dosage level should be maintained for seven days to determine the patient’s response. If no further benefit is observed at the next higher dose, dosage should be decreased to the previous lower dose. Reference ID: 3100954 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda NDA 17443/S-/S-043/S-046/S-048/S-049 Page 14 25 mg once daily for seven days, then 25 mg t.i.d. for seven days 50 mg t.i.d. for seven days 100 mg t.i.d. Therapy with a dose four times daily may be necessary for some individuals. Doses higher than 100 mg four times daily should not be used. (See Box Warning.) Pediatric Patients: The following gradual titration schedule is suggested. Some patients will not respond until higher daily dosage is achieved. Each dosage level should be maintained for seven days to determine the patient’s response. If no further benefit is observed at the next higher dose, dosage should be decreased to the previous lower dose. 0.5 mg/kg once daily for seven days, then 0.5 mg/kg t.i.d. for seven days 1 mg/kg t.i.d. for seven days 2 mg/kg t.i.d. Therapy with a dose four times daily may be necessary for some individuals. Doses higher than 100 mg four times daily should not be used. (See Box Warning.) For Malignant Hyperthermia: Preoperatively: Administer 4 to 8 mg/kg/day of oral Dantrium in 3 or 4 divided doses for one or two days prior to surgery, with the last dose being given approximately 3 to 4 hours before scheduled surgery with a minimum of water. This dosage will usually be associated with skeletal muscle weakness and sedation (sleepiness or drowsiness); adjustment can usually be made within the recommended dosage range to avoid incapacitation or excessive gastrointestinal irritation (including nausea and/or vomiting). Post Crisis Follow-up: Oral Dantrium should also be administered following a malignant hyperthermia crisis, in doses of 4 to 8 mg/kg per day in four divided doses, for a one to three day period to prevent recurrence of the manifestations of malignant hyperthermia.

NDA 17-463/S-104 Page 3 Motrin® Ibuprofen Tablets, USP Cardiovascular Risk • NSAIDs may cause an increased risk of serious cardiovascular thrombotic events, myocardial infarction, and stroke, which can be fatal. This risk may increase with duration of use. Patients with cardiovascular disease or risk factors for cardiovascular disease may be at greater risk (See WARNINGS). • MOTRIN tablets are contraindicated for treatment of peri-operative pain in the setting of coronary artery bypass graft (CABG) surgery (see WARNINGS). Gastrointestinal Risk • NSAIDs cause an increased risk of serious gastrointestinal adverse events including bleeding, ulceration, and perforation of the stomach or intestines, which can be fatal. These events can occur at any time during use and without warning symptoms. Elderly patients are at greater risk for serious gastrointestinal events. (See WARNINGS). DESCRIPTION MOTRIN tablets contain the active ingredient ibuprofen, which is (±) - 2 - (p - isobutylphenyl) propionic acid. Ibuprofen is a white powder with a melting point of 74-77° C and is very slightly soluble in water (<1 mg/mL) and readily soluble in organic solvents such as ethanol and acetone. The structural formula is represented below: MOTRIN tablets, a nonsteroidal anti-inflammatory drug (NSAID), is available in 400 mg, 600 mg, and 800 mg tablets for oral administration. Inactive ingredients: carnauba wax, colloidal silicon dioxide, croscarmellose sodium, hypromellose, lactose, magnesium stearate, microcrystalline cellulose, propylene glycol, titanium dioxide. CLINICAL PHARMACOLOGY MOTRIN tablets contain ibuprofen which possesses analgesic and antipyretic activities. Its mode of action, like that of other NSAIDs, is not completely understood, but may be related to prostaglandin synthetase inhibition. In clinical studies in patients with rheumatoid arthritis and osteoarthritis, MOTRIN tablets have been shown to be comparable to aspirin in controlling pain and inflammation and to be associated with a statistically significant reduction in the milder gastrointestinal side effects (see ADVERSE REACTIONS). MOTRIN tablets may be well tolerated in some patients who have had gastrointestinal side effects with aspirin, but these patients when treated with MOTRIN tablets should be carefully followed for signs and symptoms of gastrointestinal ulceration and bleeding. Although it is not definitely known whether MOTRIN tablets causes less peptic ulceration than aspirin, in one study involving 885 patients with rheumatoid arthritis treated for up to one year, there were no reports of NDA 17-463/S-104 Page 4 gastric ulceration with MOTRIN tablets whereas frank ulceration was reported in 13 patients in the aspirin group (statistically significant p<.001). Gastroscopic studies at varying doses show an increased tendency toward gastric irritation at higher doses. However, at comparable doses, gastric irritation is approximately half that seen with aspirin. Studies using 51Cr-tagged red cells indicate that fecal blood loss associated with MOTRIN tablets in doses up to 2400 mg daily did not exceed the normal range, and was significantly less than that seen in aspirin-treated patients. In clinical studies in patients with rheumatoid arthritis, MOTRIN tablets have been shown to be comparable to indomethacin in controlling the signs and symptoms of disease activity and to be associated with a statistically significant reduction of the milder gastrointestinal (see ADVERSE REACTIONS) and CNS side effects. MOTRIN tablets may be used in combination with gold salts and/or corticosteroids. Controlled studies have demonstrated that MOTRIN tablets are a more effective analgesic than propoxyphene for the relief of episiotomy pain, pain following dental extraction procedures, and for the relief of the symptoms of primary dysmenorrhea. In patients with primary dysmenorrhea, MOTRIN tablets have been shown to reduce elevated levels of prostaglandin activity in the menstrual fluid and to reduce resting and active intrauterine pressure, as well as the frequency of uterine contractions. The probable mechanism of action is to inhibit prostaglandin synthesis rather than simply to provide analgesia. The ibuprofen in MOTRIN tablets is rapidly absorbed. Peak serum ibuprofen levels are generally attained one to two hours after administration. With single doses up to 800 mg, a linear relationship exists between amount of drug administered and the integrated area under the serum drug concentration vs time curve. Above 800 mg, however, the area under the curve increases less than proportional to increases in dose. There is no evidence of drug accumulation or enzyme induction. The administration of MOTRIN tablets either under fasting conditions or immediately before meals yields quite similar serum ibuprofen concentration-time profiles. When MOTRIN tablets are administered immediately after a meal, there is a reduction in the rate of absorption but no appreciable decrease in the extent of absorption. The bioavailability of the drug is minimally altered by the presence of food. A bioavailability study has shown that there was no interference with the absorption of ibuprofen when MOTRIN tablets were given in conjunction with an antacid containing both aluminum hydroxide and magnesium hydroxide. Ibuprofen is rapidly metabolized and eliminated in the urine. The excretion of ibuprofen is virtually complete 24 hours after the last dose. The serum half-life is 1.8 to 2.0 hours. Studies have shown that following ingestion of the drug, 45% to 79% of the dose was recovered in the urine within 24 hours as metabolite A (25%), (+)-2-[p-(2hydroxymethyl-propyl) phenyl] propionic acid and metabolite B (37%), (+)-2-[p-(2carboxypropyl)phenyl] propionic acid; the percentages of free and conjugated ibuprofen were approximately 1% and 14%, respectively. INDICATIONS AND USAGE Carefully consider the potential benefits and risks of MOTRIN tablets and other treatment options before deciding to use MOTRIN. Use the lowest effective dose for the shortest duration consistent with individual patient treatment goals (see WARNINGS). MOTRIN tablets are indicated for relief of the signs and symptoms of rheumatoid arthritis and osteoarthritis. MOTRIN tablets are indicated for relief of mild to moderate pain. MOTRIN tablets are also indicated for the treatment of primary dysmenorrhea. NDA 17-463/S-104 Page 5 Controlled clinical trials to establish the safety and effectiveness of MOTRIN tablets in children have not been conducted. CONTRAINDICATIONS MOTRIN tablets are contraindicated in patients with known hypersensitivity to Ibuprofen. MOTRIN tablets should not be given to patients who have experienced asthma, urticaria, or allergic- type reactions after taking aspirin or other NSAIDs. Severe, rarely fatal, anaphylactic-like reactions to NSAIDs have been reported in such patients (see WARNINGS, Anaphylactoid Reactions, and PRECAUTIONS, Preexisting Asthma). MOTRIN tablets are contraindicated for the treatment of peri-operative pain in the setting of coronary artery bypass graft (CABG) surgery (see WARNINGS). WARNINGS CARDIOVASCULAR EFFECTS Cardiovascular Thrombotic Events Clinical trials of several COX-2 selective and nonselective NSAIDs of up to three years duration have shown an increased risk of serious cardiovascular (CV) thrombotic events, myocardial infarction, and stroke, which can be fatal. All NSAIDs, both COX-2 selective and nonselective, may have a similar risk. Patients with known CV disease or risk factors for CV disease may be at greater risk. To minimize the potential risk for an adverse CV event in patients treated with an NSAID, the lowest effective dose should be used for the shortest duration possible. Physicians and patients should remain alert for the development of such events, even in the absence of previous CV symptoms. Patients should be informed about the signs and/or symptoms of serious CV events and the steps to take if they occur. There is no consistent evidence that concurrent use of aspirin mitigates the increased risk of serious CV thrombotic events associated with NSAID use. The concurrent use of aspirin and an NSAID does increase the risk of serious GI events (see GI WARNINGS). Two large, controlled clinical trials of a COX-2 selective NSAID for the treatment of pain in the first 10-14 days following CABG surgery found an increased incidence of myocardial infarction and stroke (see CONTRAINDICATIONS). Hypertension NSAIDs including MOTRIN tablets, can lead to onset of new hypertension or worsening of pre- existing hypertension, either of which may contribute to the increased incidence of CV events. Patients taking thiazides or loop diuretics may have impaired response to these therapies when taking NSAIDs. NSAIDs, including MOTRIN tablets, should be used with caution in patients with hypertension. Blood pressure (BP) should be monitored closely during the initiation of NSAID treatment and throughout the course of therapy. Congestive Heart Failure and Edema Fluid retention and edema have been observed in some patients taking NSAIDs. MOTRIN tablets should be used with caution in patients with fluid retention or heart failure. Gastrointestinal Effects - Risk of Ulceration, Bleeding, and Perforation NSAIDs, including MOTRIN tablets, can cause serious gastrointestinal (GI) adverse events including inflammation, bleeding, ulceration, and perforation of the stomach, small intestine, or large intestine, NDA 17-463/S-104 Page 6 which can be fatal. These serious adverse events can occur at any time, with or without warning symptoms, in patients treated with NSAIDs. Only one in five patients, who develop a serious upper GI adverse event on NSAID therapy, is symptomatic. Upper GI ulcers, gross bleeding, or perforation caused by NSAIDs occur in approximately 1% of patients treated for 3-6 months, and in about 2-4% of patients treated for one year. These trends continue with longer duration of use, increasing the likelihood of developing a serious GI event at some time during the course of therapy. However, even short-term therapy is not without risk. NSAIDs should be prescribed with extreme caution in those with a prior history of ulcer disease or gastrointestinal bleeding. Patients with a prior history of peptic ulcer disease and/or gastrointestinal bleeding who use NSAIDs have a greater than 10-fold increased risk for developing a GI bleed compared to patients treated with neither of these risk factors. Other factors that increase the risk of GI bleeding in patients treated with NSAIDs include concomitant use of oral corticosteroids or anticoagulants, longer duration of NSAID therapy, smoking, use of alcohol, older age, and poor general health status. Most spontaneous reports of fatal GI events are in elderly or debilitated patients and therefore, special care should be taken in treating this population. To minimize the potential risk for an adverse GI event in patients treated with an NSAID, the lowest effective dose should be used for the shortest possible duration. Patients and physicians should remain alert for signs and symptoms of GI ulcerations and bleeding during NSAID therapy and promptly initiate additional evaluation and treatment if a serious GI event is suspected. This should include discontinuation of the NSAID until a serious GI adverse event is ruled out. For high-risk patients, alternate therapies that do not involve NSAIDs should be considered. Renal Effects Long-term administration of NSAIDs has resulted in renal papillary necrosis and other renal injury. Renal toxicity has also been seen in patients in whom renal prostaglandins have a compensatory role in the maintenance of renal perfusion. In these patients, administration of a NSAID may cause a dose- dependent reduction in prostaglandin formation and, secondarily, in renal blood flow, which may precipitate overt renal decompensation. Patients at greatest risk of this reaction are those with impaired renal function, heart failure, liver dysfunction, those taking diuretics and ACE inhibitors, and the elderly. Discontinuation of NSAID therapy is usually followed by recovery to the pretreatment state. Advanced Renal Disease No information is available from controlled clinical studies regarding the use of MOTRIN tablets in patients with advanced renal disease. Therefore, treatment with MOTRIN tablets is not recommended in these patients with advanced renal disease. If MOTRIN tablet therapy must be initiated, close monitoring of the patients renal function is advisable. Anaphylactoid Reactions As with other NSAIDs, anaphylactoid reactions may occur in patients without known prior exposure to MOTRIN tablets. MOTRIN tablets should not be given to patients with the aspirin triad. This symptom complex typically occurs in asthmatic patients who experience rhinitis with or without nasal polyps, or who exhibit severe, potentially fatal bronchospasm after taking aspirin or other NSAIDs (see CONTRAINDICATIONS and PRECAUTIONS, Preexisting Asthma). Emergency help should be sought in cases where an anaphylactoid reaction occurs. Skin Reactions NSAIDs, including MOTRIN tablets, can cause serious skin adverse events such as exfoliative dermatitis, Stevens-Johnson Syndrome (SJS), and toxic epidermal necrolysis (TEN), which can be fatal. These serious events may occur without warning. Patients should be informed about the signs NDA 17-463/S-104 Page 7 and symptoms of serious skin manifestations and use of the drug should be discontinued at the first appearance of skin rash or any other sign of hypersensitivity. Pregnancy In late pregnancy, as with other NSAIDs, MOTRIN tablets should be avoided because it may cause premature closure of the ductus arteriosus. PRECAUTIONS General MOTRIN tablets cannot be expected to substitute for corticosteroids or to treat corticosteroid insufficiency. Abrupt discontinuation of corticosteroids may lead to disease exacerbation. Patients on prolonged corticosteroid therapy should have their therapy tapered slowly if a decision is made to discontinue corticosteroids. The pharmacological activity of MOTRIN tablets in reducing fever and inflammation may diminish the utility of these diagnostic signs in detecting complications of presumed noninfectious, painful conditions. Hepatic effects Borderline elevations of one or more liver tests may occur in up to 15% of patients taking NSAIDs, including MOTRIN tablets. These laboratory abnormalities may progress, may remain unchanged, or may be transient with continuing therapy. Notable elevations of ALT or AST (approximately three or more times the upper limit of normal) have been reported in approximately 1% of patients in clinical trials with NSAIDs. In addition, rare cases of severe hepatic reactions, including jaundice, fulminant hepatitis, liver necrosis, and hepatic failure, some of them with fatal outcomes have been reported. A patient with symptoms and/or signs suggesting liver dysfunction, or with abnormal liver test values, should be evaluated for evidence of the development of a more severe hepatic reaction while on therapy with MOTRIN tablets. If clinical signs and symptoms consistent with liver disease develop, or if systemic manifestations occur (e.g., eosinophilia, rash, etc.), MOTRIN tablets should be dis- continued. Hematological effects Anemia is sometimes seen in patients receiving NSAIDs, including MOTRIN tablets. This may be due to fluid retention, occult or gross GI blood loss, or an incompletely described effect upon erythropoiesis. Patients on long-term treatment with NSAIDs, including MOTRIN tablets, should have their hemoglobin or hematocrit checked if they exhibit any signs or symptoms of anemia. In two postmarketing clinical studies the incidence of a decreased hemoglobin level was greater than previously reported. Decrease in hemoglobin of 1 gram or more was observed in17.1% of 193 patients on 1600 mg ibuprofen daily (osteoarthritis), and in 22.8% of 189 patients taking 2400 mg of ibuprofen daily (rheumatoid arthritis). Positive stool occult blood tests and elevated serum creatinine levels were also observed in these studies. NSAIDs inhibit platelet aggregation and have been shown to prolong bleeding time in some patients. Unlike aspirin, their effect on platelet function is quantitatively less, of shorter duration, and reversible. NDA 17-463/S-104 Page 8 Patients receiving MOTRIN tablets who may be adversely affected by alterations in platelet function, such as those with coagulation disorders or patients receiving anticoagulants should be carefully monitored. Preexisting asthma Patients with asthma may have aspirin-sensitive asthma. The use of aspirin in patients with aspirin- sensitive asthma has been associated with severe bronchospasm, which can be fatal. Since cross reactivity, including bronchospasm, between aspirin and NSAIDs has been reported in such aspirin- sensitive patients, MOTRIN tablets should not be administered to patients with this form of aspirin sensitivity and should be used with caution in patients with preexisting asthma. Ophthalmological effects Blurred and/or diminished vision, scotomata, and/or changes in color vision have been reported. If a patient develops such complaints while receiving MOTRIN tablets, the drug should be discontinued, and the patient should have an ophthalmologic examination which includes central visual fields and color vision testing. Aseptic Meningitis Aseptic meningitis with fever and coma has been observed on rare occasions in patients on ibuprofen therapy. Although it is probably more likely to occur in patients with systemic lupus erythematosus and related connective tissue diseases, it has been reported in patients who do not have an underlying chronic disease. If signs or symptoms of meningitis develop in a patient on MOTRIN tablets, the possibility of its being related to MOTRIN tablets should be considered. Information for Patients Patients should be informed of the following information before initiating therapy with an NSAID and periodically during the course of ongoing therapy. Patients should also be encouraged to read the NSAID Medication Guide that accompanies each prescription dispensed. • MOTRIN tablets like other NSAIDs, may cause serious CV side effects, such as MI or stroke, which may result in hospitalization and even death. Although serious CV events can occur without warning symptoms, patients should be alert for the signs and symptoms of chest pain, shortness of breath, weakness, slurring of speech, and should ask for medical advice when observing any indicative sign or symptoms. Patients should be apprised of the importance of this follow-up (see WARNINGS, Cardiovascular Effects). • MOTRIN tablets, like other NSAIDs, can cause GI discomfort and, rarely, serious GI side effects, such as ulcers and bleeding, which may result in hospitalization and even death. Although serious GI tract ulcerations and bleeding can occur without warning symptoms, patients should be alert for the signs and symptoms of ulcerations and bleeding, and should ask for medical advice when observing any indicative signs or symptoms including epigastric pain, dyspepsia, melena, and hematemesis. Patients should be apprised of the importance of this follow-up (see WARNINGS, Gastrointestinal Effects-Risk of Ulceration, Bleeding and Perforation). • MOTRIN tablets, like other NSAIDs, can cause serious skin side effects such as exfoliative dermatitis, SJS and TEN, which may result in hospitalization and even death. Although serious skin reactions may occur without warning, patients should be alert for the signs and symptoms NDA 17-463/S-104 Page 9 of skin rash and blisters, fever, or other signs hypersensitivity such as itching, and should ask for medical advice when observing any indicative sign or symptoms. Patients should be advised to stop the drug immediately if they develop any type of rash and contact their physicians as soon as possible. • Patients should promptly report signs or symptoms of unexplained weight gain or edema to their physicians. • Patients should be informed of the warning signs and symptoms of hepatotoxicity (e.g., nausea, fatigue, lethargy, pruritus, jaundice, right upper quadrant tenderness and “flu-like” symptoms). If these occur, patients should be instructed to stop therapy and seek immediate medical therapy. • Patients should be informed of the signs of an anaphylactoid reaction (e.g. difficulty breathing, swelling of the face or throat). If these occur, patients should be instructed to seek immediate emergency help (see WARNINGS). • In late pregnancy, as with other NSAIDs, MOTRIN tablets should be avoided because it may cause premature closure of the ductus arteriosus. Laboratory Tests Because serious GI tract ulcerations and bleeding can occur without warning symptoms, physicians should monitor for signs or symptoms of GI bleeding. Patients on long-term treatment with NSAIDs should have their CBC and chemistry profile checked periodically. If clinical signs and symptoms consistent with liver or renal disease develop, systemic manifestations occur (e.g., eosinophilia, rash etc.), or abnormal liver tests persist or worsen, MOTRIN tablets should be discontinued. Drug Interactions ACE-inhibitors: Reports suggest that NSAIDs may diminish the antihypertensive effect of ACE-inhibitors. This interaction should be given consideration in patients taking NSAIDs concomitantly with ACE- inhibitors. Aspirin When MOTRIN tablets are administered with aspirin, its protein binding is reduced, although the clearance of free MOTRIN tablets is not altered. The clinical significance of this interaction is not known; however, as with other NSAIDs, concomitant administration of ibuprofen and aspirin is not generally recommended because of the potential for increased adverse effects. Diuretics Clinical studies, as well as post marketing observations, have shown that MORTIN tablets can reduce the natriuretic effect-of furosemide and thiazides in some patients. This response has been attributed to inhibition of renal prostaglandin synthesis. During concomitant therapy with NSAIDs, the patient should be observed closely for signs of renal failure (see PRECAUTIONS, Renal Effects), as well as to assure diuretic efficacy. NDA 17-463/S-104 Page 10 Lithium Ibuprofen produced an elevation of plasma lithium levels and a reduction in renal lithium clearance in a study of eleven normal volunteers. The mean minimum lithium concentration increased 15% and the renal clearance of lithium was decreased by 19% during this period of concomitant drug administration. This effect has been attributed to inhibition of renal prostaglandin synthesis by ibuprofen. Thus, when ibuprofen and lithium are administered concurrently, subjects should be observed carefully for signs of lithium toxicity. (Read circulars for lithium preparation before use of such concurrent therapy.) Methotrexate NSAIDs have been reported to competitively inhibit methotrexate accumulation in rabbit kidney slices. This may indicate that they could enhance the toxicity of methotrexate. Caution should be used when NSAIDs are administered concomitantly with methotrexate. Warfarin-type anticoagulants Several short-term controlled studies failed to show that MOTRIN tablets significantly affected prothrombin times or a variety of other clotting factors when administered to individuals on coumarin- type anticoagulants. However, because bleeding has been reported when MOTRIN tablets and other NSAIDs have been administered to patients on coumarin-type anticoagulants, the physician should be cautious when administering MOTRIN tablets to patients on anticoagulants. The effects of warfarin and NSAIDs on GI bleeding are synergistic, such that the users of both drugs together have a risk of serious GI bleeding higher than users of either drug alone. H-2 Antagonists In studies with human volunteers, co-administration of cimetidine or ranitidine with ibuprofen had no substantive effect on ibuprofen serum concentrations. Pregnancy Teratogenic effects: Pregnancy Category C Reproductive studies conducted in rats and rabbits have not demonstrated evidence of developmental abnormalities. However, animal reproduction studies are not always predictive of human response. There are no adequate and well-controlled studies in pregnant women. Motrin should be used in pregnancy only if the potential benefit justifies the potential risk to the fetus. Nonteratogenic effects Because of the known effects of NSAIDs on the fetal cardiovascular system (closure of ductus arteriosus), use during late pregnancy should be avoided. Labor and Delivery In rat studies with NSAIDs, as with other drugs known to inhibit prostaglandin synthesis, an increased incidence of dystocia, delayed parturition, and decreased pup survival occurred. The effects of MOTRIN tablets on labor and delivery in pregnant women are unknown. Nursing Mothers It is not known whether this drug is excreted in human milk. Because many drugs are excreted in human-milk and because of the potential for serious adverse reactions in nursing infants from NDA 17-463/S-104 Page 11 MOTRIN tablets, a decision should be made whether to discontinue nursing or discontinue the drug, taking into account the importance of the drug to the mother. Pediatric Use Safety and effectiveness of MOTRIN tablets in pediatric patients have not been established. Geriatric Use As with any NSAIDs, caution should be exercised in treating the elderly (65 years and older). ADVERSE REACTIONS The most frequent type of adverse reaction occurring with MOTRIN tablets is gastrointestinal. In controlled clinical trials the percentage of patients reporting one or more gastrointestinal complaints ranged from 4% to 16%. In controlled studies when MOTRIN tablets were compared to aspirin and indomethacin in equally effective doses, the overall incidence of gastrointestinal complaints was about half that seen in either the aspirin- or indomethacin-treated patients. Adverse reactions observed during controlled clinical trials at an incidence greater than 1% are listed in the table. Those reactions listed in Column one encompass observations in approximately 3,000 patients. More than 500 of these patients were treated for periods of at least 54 weeks. Still other reactions occurring less frequently than 1 in 100 were reported in controlled clinical trials and from marketing experience. These reactions have been divided into two categories: Column two of the table lists reactions with therapy with MOTRIN tablets where the probability of a causal relationship exists: for the reactions in Column three, a causal relationship with MOTRIN tablets has not been established. Reported side effects were higher at doses of 3200 mg/day than at doses of 2400 mg or less per day in clinical trials of patients with rheumatoid arthritis. The increases in incidence were slight and still within the ranges reported in the table.

Reactions are classified under "Causal Relationship Unknown" if seven or more events have been reported but the criteria for PCR have not been met. NDA 17-463/S-104 Page 13 OVERDOSAGE Approximately 1½ hours after the reported ingestion of from 7 to 10 MOTRIN tablets (400 mg), a 19-month old child weighing 12 kg was seen in the hospital emergency room, apneic and cyanotic, responding only to painful stimuli. This type of stimulus, however, was sufficient to induce respiration. Oxygen and parenteral fluids were given; a greenish-yellow fluid was aspirated from the stomach with no evidence to indicate the presence of ibuprofen. Two hours after ingestion the child’s condition seemed stable; she still responded only to painful stimuli and continued to have periods of apnea lasting from 5 to 10 seconds. She was admitted to intensive care and sodium bicarbonate was administered as well as infusions of dextrose and normal saline. By four hours post-ingestion she could be aroused easily, sit by herself and respond to spoken commands. Blood level of ibuprofen was 102.9 µg/mL approximately 8½ hours after accidental ingestion. At 12 hours she appeared to be completely recovered. In two other reported cases where children (each weighing approximately 10 kg) accidentally, acutely ingested approximately 120 mg/kg, there were no signs of acute intoxication or late sequelae. Blood level in one child 90 minutes after ingestion was 700 µg/mL — about 10 times the peak levels seen in absorption-excretion studies. A 19-year old male who had taken 8,000 mg of ibuprofen over a period of a few hours complained of dizziness, and nystagmus was noted. After hospitalization, parenteral hydration and three days bed rest, he recovered with no reported sequelae. In cases of acute overdosage, the stomach should be emptied by vomiting or lavage, though little drug will likely be recovered if more than an hour has elapsed since ingestion. Because the drug is acidic and is excreted in the urine, it is theoretically beneficial to administer alkali and induce diuresis. In addition to supportive measures, the use of oral activated charcoal may help to reduce the absorption and reabsorption of MOTRIN tablets. DOSAGE AND ADMINISTRATION Carefully consider the potential benefits and risks of MOTRIN tablets and other treatment options before deciding to use MOTRIN tablets. Use the lowest effective dose for the shortest duration consistent with individual patient treatment goals (see WARNINGS). After observing the response to initial therapy with MOTRIN tablets, the dose and frequency should be adjusted to suit an individual patient’s needs. Do not exceed 3200 mg total daily dose. If gastrointestinal complaints occur, administer MOTRIN tablets with meals or milk. Rheumatoid arthritis and osteoarthritis, including flare-ups of chronic disease: Suggested Dosage: 1200 mg-3200 mg daily (300 mg qid; 400 mg, 600 mg or 800 mg tid or qid). Individual patients may show a better response to 3200 mg daily, as compared with 2400 mg, although in well-controlled clinical trials patients on 3200 mg did not show a better mean response in terms of efficacy. Therefore, when treating patients with 3200 mg/day, the physician should observe sufficient increased clinical benefits to offset potential increased risk. The dose should be tailored to each patient, and may be lowered or raised depending on the severity of symptoms either at time of initiating drug therapy or as the patient responds or fails to respond. In general, patients with rheumatoid arthritis seem to require higher doses of MOTRIN tablets than do patients with osteoarthritis. NDA 17-463/S-104 Page 14 The smallest dose of MOTRIN tablets that yields acceptable control should be employed. A linear blood level dose-response relationship exists with single doses up to 800 mg (See CLINICAL PHARMACOLOGY for effects of food on rate of absorption). The availability of four tablet strengths facilitates dosage adjustment. In chronic conditions, a therapeutic response to therapy with MOTRIN tablets is sometimes seen in a few days to a week but most often is observed by two weeks. After a satisfactory response has been achieved, the patient’s dose should be reviewed and adjusted as required. Mild to moderate pain: 400 mg every 4 to 6 hours as necessary for relief of pain. In controlled analgesic clinical trials, doses of MOTRIN tablets greater than 400 mg were no more effective than the 400 mg dose. Dysmenorrhea: For the treatment of dysmenorrhea, beginning with the earliest onset of such pain, MOTRIN tablets should be given in a dose of 400 mg every 4 hours as necessary for the relief of pain.

What is the most important information I should know about medicines called Non- Steroidal Anti-Inflammatory Drugs (NSAIDs)? NSAID medicines may increase the chance of a heart attack or stroke that can lead to death. This chance increases: • with longer use of NSAID medicines • in people who have heart disease NSAID medicines should never be used right before or after a heart surgery called a “coronary artery bypass graft (CABG).” NSAID medicines can cause ulcers and bleeding in the stomach and intestines at any time during treatment. Ulcers and bleeding: • can happen without warning symptoms • may cause death The chance of a person getting an ulcer or bleeding increases with: • taking medicines called “corticosteroids” and “anticoagulants” • longer use • smoking • drinking alcohol • older age • having poor health NSAID medicines should only be used: • exactly as prescribed • at the lowest dose possible for your treatment • for the shortest time needed What are Non-Steroidal Anti-Inflammatory Drugs (NSAIDs)? NSAID medicines are used to treat pain and redness, swelling, and heat (inflammation) from medical conditions such as: • different types of arthritis • menstrual cramps and other types of short-term pain NDA 17-463/S-104 Page 16 Who should not take a Non-Steroidal Anti-Inflammatory Drug (NSAID)? Do not take an NSAID medicine: • if you had an asthma attack, hives, or other allergic reaction with aspirin or any other NSAID medicine • for pain right before or after heart bypass surgery Tell your healthcare provider: • about all your medical conditions. • about all of the medicines you take. NSAIDs and some other medicines can interact with each other and cause serious side effects. Keep a list of your medicines to show to your healthcare provider and pharmacist. • if you are pregnant. NSAID medicines should not be used by pregnant women late in their pregnancy. • if you are breastfeeding. Talk to your doctor. What are the possible side effects of Non-Steroidal Anti-Inflammatory Drugs (NSAIDs)? Serious side effects include: • heart attack • stroke • high blood pressure • heart failure from body swelling (fluid retention) • kidney problems including kidney failure • bleeding and ulcers in the stomach and intestine • low red blood cells (anemia) • life-threatening skin reactions • life-threatening allergic reactions • liver problems including liver failure • asthma attacks in people who have asthma Other side effects include: • stomach pain • constipation • diarrhea • gas • heartburn • nausea • vomiting • dizziness Get emergency help right away if you have any of the following symptoms: • shortness of breath or trouble breathing • slurred speech • chest pain • swelling of the face or throat • weakness in one part or side of your body Stop your NSAID medicine and call your healthcare provider right away if you have any of the following symptoms: • nausea • more tired or weaker than usual • itching • your skin or eyes look yellow • stomach pain • flu-like symptoms • vomit blood • there is blood in your bowel movement or it is black and sticky like tar • unusual weight gain • skin rash or blisters with fever • swelling of the arms and legs, hands and feet These are not all the side effects with NSAID medicines. Talk to your healthcare provider or pharmacist for more information about NSAID medicines. NDA 17-463/S-104 Page 17 Other information about Non-Steroidal Anti-Inflammatory Drugs (NSAIDs) • Aspirin is an NSAID medicine but it does not increase the chance of a heart attack. Aspirin can cause bleeding in the brain, stomach, and intestines. Aspirin can also cause ulcers in the stomach and intestines. • Some of these NSAID medicines are sold in lower doses without a prescription (over-the-counter). Talk to your healthcare provider before using over-the-counter NSAIDs for more than 10 days.

NDA 17-468/S-019 NDA 17-469/S-031 Page 3 Packaging Insert 1/8% Econopred   1 % Econopred  Plus (prednisolone acetate ophthalmic suspension) DESCRIPTION: ECONOPRED and ECONOPRED Plus (Prednisolone Acetate ophthalmic suspension) are adrenocortical steroid products prepared as sterile ophthalmic suspensions. The active ingredient is represented by the chemical structure: [Structure] Established name: Prednisolone Acetate Chemical name: Pregna-1,4-diene-3,20-dione,21-(acetyloxy)-11,17-dihydroxy-,(11β)-. Each mL contains: Active: prednisolone acetate 1.0% or 0.125%. Preservative: benzalkonium chloride 0.01 %. Vehicle: hydroxypropyl methylcellulose. Inactive: dibasic sodium phosphate, polysorbate 80, edetate disodium, glycerin, citric acid and/or sodium hydroxide (to adjust pH), purified water. CLINICAL PHARMACOLOGY: Corticosteroids inhibit the inflammatory response to a variety of inciting agents and probably delay or slow healing. They inhibit the edema, fibrin deposition, capillary dilation, leukocyte migration, capillary proliferation, fibroblast proliferation, deposition of collagen, and scar formation associated with inflammation. There is no generally accepted explanation for the mechanism of action of ocular corticosteroids. However, corticosteroids are thought to act by the induction of phospholipase A2 inhibitory proteins, collectively called lipocortins. It is postulated that these proteins control the biosynthesis of potent mediators of inflammation such as prostaglandins and leukotrienes by inhibiting the release of their common precursor arachidonic acid. Arachidonic acid is released from membrane phospholipids by phospholipase A2. Corticosteroids are capable of producing a rise in intraocular pressure. INDICATIONS AND USAGE: Steroid responsive inflammatory conditions of the palpebral and bulbar conjunctiva, cornea, and anterior segment of the globe such as allergic conjunctivitis, acne rosacea, superficial punctate keratitis, herpes zoster keratitis, iritis, cyclitis, selected infective conjunctivitides, when the inherent hazard of steroid use is accepted to obtain an advisable diminution in edema and inflammation; corneal injury from chemical, radiation, or thermal burns, or penetration of foreign bodies. CONTRAINDICATIONS: ECONOPRED and ECONOPRED Plus (prednisolone acetate ophthalmic suspension) are contraindicated in most viral diseases of the cornea and conjunctiva including epithelial herpes simplex keratitis (dendritic keratitis), vaccinia, and varicella, and also in mycobacterial infection of the eye and fungal diseases of ocular structures. ECONOPRED and This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda NDA 17-468/S-019 NDA 17-469/S-031 Page 4 ECONOPRED Plus (prednisolone acetate ophthalmic suspension) are also contraindicated in individuals with known or suspected hypersensitivity to any of the ingredients of this preparation and to other corticosteroids. WARNINGS: FOR TOPICAL OPHTHALMIC USE ONLY. Prolonged use of corticosteroids may result in glaucoma with damage to the optic nerve, defects in visual acuity and fields of vision, and in posterior subcapsular cataract formation. Prolonged use may also suppress the host immune response and thus increase the hazard of secondary ocular infections. Various ocular diseases and long-term use of topical corticosteroids have been known to cause corneal and scleral thinning. Use of topical corticosteroids in the presence of thin corneal or scleral tissue may lead to perforation. Acute purulent infections of the eye may be masked or activity enhanced by the presence of corticosteroid medication. If this product is used for 10 days or longer, intraocular pressure should be routinely monitored even though it may be difficult in children and uncooperative patients. Steroids should be used with caution in the presence of glaucoma. Intraocular pressure should be checked frequently. The use of steroids after cataract surgery may delay healing and increase the incidence of bleb formation. Use of ocular steroids may prolong the course and may exacerbate the severity of many viral infections of the eye (including herpes simplex). Employment of a corticosteroid medication in the treatment of patients with a history of herpes simplex requires great caution; frequent slit lamp microscopy is recommended. Corticosteroids are not effective in mustard gas keratitis and Sjögren's keratoconjunctivitis. PRECAUTIONS: General: The initial prescription and renewal of the medication order should be made by a physician only after examination of the patient with the aid of magnification, such as slit lamp biomicroscopy and, where appropriate, fluorescein staining. If signs and symptoms fail to improve after two days, the patient should be re-evaluated. As fungal infections of the cornea are particularly prone to develop coincidentally with long-term local corticosteroid applications, fungal invasion should be suspected in any persistent corneal ulceration where a corticosteroid has been used or is in use. Fungal cultures should be taken when appropriate. If this product is used for 10 days or longer, intraocular pressure should be monitored (SEE WARNINGS). Information for Patients: If inflammation or pain persists longer than 48 hours or becomes aggravated, the patient should be advised to discontinue use of the medication and consult a physician. This product is sterile when packaged. To prevent contamination, care should be taken to avoid touching the bottle tip to eyelids or to any other surface. The use of this bottle by more than one person may spread infection. Keep bottle tightly closed when not in use. Keep out of the reach of children. Carcinogenesis, Mutagenesis, Impairment of Fertility: No studies have been conducted in animals or in humans to evaluate the potential of these effects. Pregnancy: Teratogenic effects. Pregnancy Category C. Prednisolone has been shown to be teratogenic in mice when given in doses 1-10 times the human dose. Dexamethasone, hydrocortisone and prednisolone were ocularly applied to both eyes of pregnant mice five times per day on days 10 through 13 of gestation. A significant increase in the incidence of cleft palate was observed in the This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda NDA 17-468/S-019 NDA 17-469/S-031 Page 5 fetuses of the treated mice. There are no adequate and well controlled studies in pregnant women. ECONOPRED and ECONOPRED Plus (prednisolone acetate ophthalmic suspension) should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus. Nursing Mothers: It is not known whether topical administration of corticosteroids could result in sufficient systemic absorption to produce detectable quantities in human milk. Systemically administered corticosteroids appear in human milk and could suppress growth, interfere with endogenous corticosteroid production, or cause other untoward effects. Because of the potential for serious adverse reactions in nursing infants from prednisolone acetate, a decision should be made whether to discontinue nursing or to discontinue the drug, taking into account the importance of the drug to the mother. Pediatric Use: Safety and effectiveness in pediatric patients have not been established. Geriatric Use: No overall differences in safety or effectiveness have been observed between elderly and younger patients. ADVERSE REACTIONS: Adverse reactions include, in decreasing order of frequency, elevation of intraocular pressure (IOP) with possible development of glaucoma and infrequent optic nerve damage, posterior subcapsular cataract formation, and delayed wound healing. Although systemic effects are extremely uncommon, there have been rare occurrences of systemic hypercorticoidism after use of topical steroids. Corticosteroid-containing preparations have also been reported to cause acute anterior uveitis and perforation of the globe. Keratitis, conjunctivitis, corneal ulcers, mydriasis, conjunctival hyperemia, loss of accommodation and ptosis have occasionally been reported following local use of corticosteroids. The development of secondary ocular infection (bacterial, fungal and viral) has occurred. Fungal and viral infections of the cornea are particularly prone to develop coincidentally with long-term applications of steroid. The possibility of fungal invasion should be considered in any persistent corneal ulceration where steroid treatment has been used (SEE WARNINGS). DOSAGE AND ADMINISTRATION: SHAKE WELL BEFORE USING. Two drops topically in the eye(s) four times daily. In cases of bacterial infections, concomitant use of anti-infective agents is mandatory. Care should be taken not to discontinue therapy prematurely. If signs and symptoms fail to improve after two days, the patient should be re-evaluated (SEE PRECAUTIONS). The dosing of ECONOPRED and ECONOPRED Plus may be reduced, but care should be taken not to discontinue therapy prematurely. In chronic conditions, withdrawal of treatment should be carried out by gradually decreasing the frequency of applications.

NDA 17-469/S-040 Page 3 Omnipred™ (prednisolone acetate ophthalmic suspension) DESCRIPTION: Omnipred™ (prednisolone acetate ophthalmic suspension) is an adrenocortical steroid product prepared as sterile ophthalmic suspension. The active ingredient is represented by the chemical structure: --- CHEMICAL STRUCTURE --- Established name: Prednisolone Acetate Chemical name: Pregna-1,4-diene-3,20-dione,21-(acetyloxy)-11,17-dihydroxy-,(11β)-.

CONTRAINDICATIONS: Omnipred™ (prednisolone acetate ophthalmic suspension) is contraindicated in most viral diseases of the cornea and conjunctiva including epithelial herpes simplex keratitis (dendritic keratitis), vaccinia, and varicella, and also in mycobacterial infection of the eye and fungal diseases of ocular structures. Omnipred™ (prednisolone acetate ophthalmic suspension) is also contraindicated in individuals with known or suspected hypersensitivity to any of the ingredients of This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda NDA 17-469/S-040 Page 4 this preparation and to other corticosteroids. WARNINGS: FOR TOPICAL OPHTHALMIC USE ONLY. Prolonged use of corticosteroids may result in glaucoma with damage to the optic nerve, defects in visual acuity and fields of vision, and in posterior subcapsular cataract formation. Prolonged use may also suppress the host immune response and thus increase the hazard of secondary ocular infections. Various ocular diseases and long-term use of topical corticosteroids have been known to cause corneal and scleral thinning. Use of topical corticosteroids in the presence of thin corneal or scleral tissue may lead to perforation. Acute purulent infections of the eye may be masked or activity enhanced by the presence of corticosteroid medication. If this product is used for 10 days or longer, intraocular pressure should be routinely monitored even though it may be difficult in children and uncooperative patients. Steroids should be used with caution in the presence of glaucoma. Intraocular pressure should be checked frequently. The use of steroids after cataract surgery may delay healing and increase the incidence of bleb formation. Use of ocular steroids may prolong the course and may exacerbate the severity of many viral infections of the eye (including herpes simplex). Employment of a corticosteroid medication in the treatment of patients with a history of herpes simplex requires great caution; frequent slit lamp microscopy is recommended. Corticosteroids are not effective in mustard gas keratitis and Sjögren’s keratoconjunctivitis. PRECAUTIONS: General: The initial prescription and renewal of the medication order should be made by a physician only after examination of the patient with the aid of magnification, such as slit lamp biomicroscopy and, where appropriate, fluorescein staining. If signs and symptoms fail to improve after two days, the patient should be re-evaluated. As fungal infections of the cornea are particularly prone to develop coincidentally with long-term local corticosteroid applications, fungal invasion should be suspected in any persistent corneal ulceration where a corticosteroid has been used or is in use. Fungal cultures should be taken when appropriate. If this product is used for 10 days or longer, intraocular pressure should be monitored (SEE WARNINGS). Information for Patients: If inflammation or pain persists longer than 48 hours or becomes aggravated, the patient should be advised to discontinue use of the medication and consult a physician. This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda NDA 17-469/S-040 Page 5 This product is sterile when packaged. To prevent contamination, care should be taken to avoid touching the bottle tip to eyelids or to any other surface. The use of this bottle by more than one person may spread infection. Keep bottle tightly closed when not in use. Keep out of the reach of children. Carcinogenesis, Mutagenesis, Impairment of Fertility: No studies have been conducted in animals or in humans to evaluate the potential of these effects. Pregnancy: Teratogenic effects. Pregnancy Category C. Prednisolone has been shown to be teratogenic in mice when given in doses 1-10 times the human dose. Dexamethasone, hydrocortisone and prednisolone were ocularly applied to both eyes of pregnant mice five times per day on days 10 through 13 of gestation. A significant increase in the incidence of cleft palate was observed in the fetuses of the treated mice. There are no adequate and well controlled studies in pregnant women. Omnipred™ (prednisolone acetate ophthalmic suspension) should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus. Nursing Mothers: It is not known whether topical administration of corticosteroids could result in sufficient systemic absorption to produce detectable quantities in human milk. Systemically administered corticosteroids appear in human milk and could suppress growth, interfere with endogenous corticosteroid production, or cause other untoward effects. Because of the potential for serious adverse reactions in nursing infants from prednisolone acetate, a decision should be made whether to discontinue nursing or to discontinue the drug, taking into account the importance of the drug to the mother. Pediatric Use: Safety and effectiveness in pediatric patients have not been established. Geriatric Use: No overall differences in safety or effectiveness have been observed between elderly and younger patients. ADVERSE REACTIONS: Adverse reactions include, in decreasing order of frequency, elevation of intraocular pressure (IOP) with possible development of glaucoma and infrequent optic nerve damage, posterior subcapsular cataract formation, and delayed wound healing. Although systemic effects are extremely uncommon, there have been rare occurrences of systemic hypercorticoidism after use of topical steroids. Corticosteroid-containing preparations have also been reported to cause acute anterior uveitis and perforation of the globe. Keratitis, conjunctivitis, corneal ulcers, mydriasis, conjunctival hyperemia, This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda NDA 17-469/S-040 Page 6 loss of accommodation and ptosis have occasionally been reported following local use of corticosteroids. The development of secondary ocular infection (bacterial, fungal and viral) has occurred. Fungal and viral infections of the cornea are particularly prone to develop coincidentally with long-term applications of steroid. The possibility of fungal invasion should be considered in any persistent corneal ulceration where steroid treatment has been used (SEE WARNINGS). DOSAGE AND ADMINISTRATION: SHAKE WELL BEFORE USING. Two drops topically in the eye(s) four times daily. In cases of bacterial infections, concomitant use of anti-infective agents is mandatory. Care should be taken not to discontinue therapy prematurely. If signs and symptoms fail to improve after two days, the patient should be re-evaluated (SEE PRECAUTIONS). The dosing of Omnipred™ suspension may be reduced, but care should be taken not to discontinue therapy prematurely. In chronic conditions, withdrawal of treatment should be carried out by gradually decreasing the frequency of applications.

1 XXXXXX ORAP® (Pimozide) Tablets GATE 151 187 DESCRIPTION ORAP ® (pimozide) is an orally active antipsychotic agent of the diphenyl-butylpiperidine series. The structural formula of pimozide, 1-[1-[4,4-bis(4-fluorophenyl) butyl]-4­ piperidinyl]-1,3-dihydro-2H-benzimidazole-2-one is: structural formula The solubility of pimozide in water is less than 0.01 mg/mL; it is slightly soluble in most organic solvents. Each white ORAP tablet contains either 1 mg or 2 mg of pimozide and the following inactive ingredients: calcium stearate, microcrystalline cellulose, lactose anhydrous and corn starch. CLINICAL PHARMACOLOGY Pharmacodynamic Actions ORAP (pimozide) is an orally active antipsychotic drug product which shares with other antipsychotics the ability to blockade dopaminergic receptors on neurons in the central nervous system. Although its exact mode of action has not been established, the ability of pimozide to suppress motor and phonic tics in Tourette’s Disorder is thought to be a function of its dopaminergic blocking activity. However, receptor blockade is often accompanied by a series of secondary alterations in central dopamine metabolism and function which may contribute to both pimozide’s therapeutic and untoward effects. In addition, pimozide, in common with other antipsychotic drugs, has various effects on other central nervous system receptor systems which are not fully characterized. Metabolism and Pharmacokinetics More than 50% of a dose of pimozide is absorbed after oral administration. Based on the pharmacokinetic and metabolic profile, pimozide appears to undergo significant first pass Reference ID: 2870808 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda 2 metabolism. Peak serum levels occur generally six to eight hours (range 4-12 hours) after dosing. Pimozide is extensively metabolized, primarily by N-dealkylation in the liver. This metabolism is catalyzed mainly by the cytochrome P450 3A4 (CYP 3A4) enzymatic system and to a lesser extent, by cytochrome P450 1A2 (CYP 1A2). Two major metabolites have been identified, 1-(4-piperidyl)-2-benzimidazolinone and 4,4-bis(4­ fluorophenyl) butyric acid. The antipsychotic activity of these metabolites is undetermined. The major route of elimination of pimozide and its metabolites is through the kidney. The mean serum elimination half-life of pimozide in schizophrenic patients was approximately 55 hours. There was a 13-fold interindividual difference in the area under the serum pimozide level-time curve and an equivalent degree of variation in peak serum levels among patients studied. The significance of this is unclear since there are few correlations between plasma levels and clinical findings. Effects of food and disease upon the absorption, distribution, metabolism and elimination of pimozide are not known. Effects of concomitant medication on pimozide metabolism are described in the CONTRAINDICATIONS section. INDICATIONS AND USAGE ORAP (pimozide) is indicated for the suppression of motor and phonic tics in patients with Tourette’s Disorder who have failed to respond satisfactorily to standard treatment. ORAP is not intended as a treatment of first choice nor is it intended for the treatment of tics that are merely annoying or cosmetically troublesome. ORAP should be reserved for use in Tourette’s Disorder patients whose development and/or daily life function is severely compromised by the presence of motor and phonic tics. Evidence supporting approval of pimozide for use in Tourette’s Disorder was obtained in two controlled clinical investigations which enrolled patients between the ages of 8 and 53 years. Most subjects in the two trials were 12 or older. CONTRAINDICATIONS 1. ORAP (pimozide) is contraindicated in the treatment of simple tics or tics other than those associated with Tourette’s Disorder. 2. ORAP should not be used in patients taking drugs that may, themselves, cause motor and phonic tics (e.g., pemoline, methylphenidate and amphetamines) until such patients have been withdrawn from these drugs to determine whether or not the drugs, rather than Tourette’s Disorder, are responsible for the tics. 3. Because ORAP prolongs the QT interval of the electrocardiogram it is contraindicated in patients with congenital long QT syndrome, patients with a history of cardiac arrhythmias, patients taking other drugs which prolong the QT interval of the electrocardiogram or patients with known hypokalemia or hypomagnesemia (see also PRECAUTIONS - Drug Interactions). Reference ID: 2870808 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda 3 4. ORAP is contraindicated in patients with severe toxic central nervous system depression or comatose states from any cause. 5. ORAP is contraindicated in patients with hypersensitivity to it. As it is not known whether cross-sensitivity exists among the antipsychotics, pimozide should be used with appropriate caution in patients who have demonstrated hypersensitivity to other antipsychotic drugs. 6. Ventricular arrhythmias have been rarely associated with the use of macrolide antibiotics in patients with prolonged QT intervals, as might be produced by ORAP. Specifically, two sudden deaths have been reported when clarithromycin was added to ongoing pimozide therapy. Furthermore, some evidence suggests that pimozide is metabolized partly by the enzyme system cytochrome P450 3A4 (CYP 3A4). Macrolide antibiotics are inhibitors of CYP 3A4, and thus could potentially impede pimozide metabolism. For these reasons, ORAP is contraindicated in patients receiving the macrolide antibiotics clarithromycin, erythromycin, azithromycin, dirithromycin, and troleandomycin. 7. Concomitant use in patients taking Celexa or Lexapro is contraindicated (see Precautions - Drug Interactions - Pimozide and Celexa). Because azole antifungal agents are also inhibitors of the CYP 3A4 enzymes and thus may likewise impair pimozide metabolism, ORAP is contraindicated in patients receiving the azole antifungal agents itraconazole and ketoconazole. Similarly, protease inhibitor drugs are also inhibitors of CYP 3A4, and thus ORAP is contraindicated in patients receiving protease inhibitors such as ritonavir, saquinovir, indinavir, and nelfinavir. (See PRECAUTIONS - Drug Interactions.) Nefazodone is a potent inhibitor of CYP 3A4, and its concomitant use with ORAP is also contraindicated. Other drugs that are relatively less potent inhibitors of CYP 3A4 should also be avoided, in view of the risks: e.g. zileuton, fluvoxamine. Concomitant use of pimozide in patients taking sertraline is contraindicated (See PRECAUTIONS - Drug Interactions). WARNINGS The use of ORAP (pimozide) in the treatment of Tourette’s Disorder involves different risk/benefit considerations than when antipsychotic drugs are used to treat other conditions. Consequently, a decision to use ORAP should take into consideration the following (see also PRECAUTIONS - Information for Patients). Tardive Dyskinesia Reference ID: 2870808 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda 4 A syndrome consisting of potentially irreversible, involuntary, dyskinetic movements may develop in patients treated with antipsychotic drugs. Although the prevalence of the syndrome appears to be highest among the elderly, especially elderly women, it is impossible to rely upon prevalence estimates to predict, at the inception of antipsychotic treatment, which patients are likely to develop the syndrome. Whether antipsychotic drug products differ in their potential to cause tardive dyskinesia is unknown. Both the risk of developing tardive dyskinesia and the likelihood that it will become irreversible are believed to increase as the duration of treatment and the total cumulative dose of antipsychotic drugs administered to the patient increase. However, the syndrome can develop, although much less commonly, after relatively brief treatment periods at low doses. There is no known treatment for established cases of tardive dyskinesia, although the syndrome may remit, partially or completely, if antipsychotic treatment is withdrawn. Antipsychotic treatment itself, however, may suppress (or partially suppress) the signs and symptoms of the syndrome and thereby may possibly mask the underlying process. The effect that symptomatic suppression has upon the long-term course of the syndrome is unknown. Given these considerations, antipsychotic drugs should be prescribed in a manner that is most likely to minimize the occurrence of tardive dyskinesia. Chronic antipsychotic treatment should generally be reserved for patients who suffer from a chronic illness that, 1) is known to respond to antipsychotic drugs, and, 2) for whom alternative, equally effective, but potentially less harmful treatments are not available or appropriate. In patients who do require chronic treatment, the smallest dose and the shortest duration of treatment producing a satisfactory clinical response should be sought. The need for continued treatment should be reassessed periodically. If signs and symptoms of tardive dyskinesia appear in a patient on antipsychotics, drug discontinuation should be considered. However, some patients may require treatment despite the presence of the syndrome. (For further information about the description of tardive dyskinesia and its clinical detection, please refer to ADVERSE REACTIONS and PRECAUTIONS - Information for Patients.) Neuroleptic Malignant Syndrome (NMS) A potentially fatal symptom complex sometimes referred to as Neuroleptic Malignant Syndrome (NMS) has been reported in association with antipsychotic drugs. Clinical manifestations of NMS are hyperpyrexia, muscle rigidity, altered mental status (including catatonic signs) and evidence of autonomic instability (irregular pulse or blood pressure, tachycardia, diaphoresis, and cardiac dysrhythmias). Additional signs may include elevated creatine phosphokinase, myoglobinuria (rhabdomyolysis) and acute renal failure. Reference ID: 2870808 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda 5 The diagnostic evaluation of patients with this syndrome is complicated. In arriving at a diagnosis, it is important to identify cases where the clinical presentation includes both serious medical illness (e.g., pneumonia, systemic infection, etc.) and untreated or inadequately treated extrapyramidal signs and symptoms (EPS). Other important considerations in the differential diagnosis include central anticholinergic toxicity, heat stroke, drug fever and primary central nervous system (CNS) pathology. The management of NMS should include 1) immediate discontinuation of antipsychotic drugs and other drugs not essential to concurrent therapy, 2) intensive symptomatic treatment and medical monitoring, and 3) treatment of any concomitant serious medical problems for which specific treatments are available. There is no general agreement about specific pharmacological treatment regimens for uncomplicated NMS. If a patient requires antipsychotic drug treatment after recovery from NMS, the potential reintroduction of drug therapy should be carefully considered. The patient should be carefully monitored, since recurrences of NMS have been reported. Hyperpyrexia, not associated with the above symptom complex, has been reported with other antipsychotic drugs. Other Sudden, unexpected deaths have occurred in experimental studies of conditions other than Tourette’s Disorder. These deaths occurred while patients were receiving dosages in the range of 1 mg per kg. One possible mechanism for such deaths is prolongation of the QT interval predisposing patients to ventricular arrhythmia. An electrocardiogram should be performed before ORAP treatment is initiated and periodically thereafter, especially during the period of dose adjustment. ORAP may have a tumorigenic potential. Based on studies conducted in mice, it is known that pimozide can produce a dose-related increase in pituitary tumors. The full significance of this finding is not known, but should be taken into consideration in the physician’s and patient’s decisions to use this drug product. This finding should be given special consideration when the patient is young and chronic use of pimozide is anticipated (see PRECAUTIONS - Carcinogenesis, Mutagenesis, Impairment of Fertility). PRECAUTIONS Leukopenia, Neutropenia and Agranulocytosis Class Effect: In clinical trial and/or postmarketing experience, events of leukopenia/neutropenia and agranulocytosis have been reported temporally related to antipsychotic agents. Possible risk factors for leukopenia/neutropenia include preexisting low white blood cell count (WBC) and history of drug induced leukopenia/neutropenia. Patients with a history of a clinically significant low WBC or drug induced leukopenia/neutropenia should have their complete blood count (CBC) monitored frequently during the first few Reference ID: 2870808 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda 6 months of therapy and discontinuation of ORAP should be considered at the first sign of a clinically significant decline in WBC in the absence of other causative factors. Patients with clinically significant neutropenia should be carefully monitored for fever or other symptoms or signs of infection and treated promptly if such symptoms or signs occur. Patients with severe neutropenia (absolute neutrophil count <1000/mm3) should discontinue ORAP and have their WBC followed until recovery. General ORAP (pimozide) may impair the mental and/or physical abilities required for the performance of potentially hazardous tasks, such as driving a car or operating machinery, especially during the first few days of therapy. ORAP produces anticholinergic side effects and should be used with caution in individuals whose conditions may be aggravated by anticholinergic activity. ORAP should be administered cautiously to patients with impairment of liver or kidney function, because it is metabolized by the liver and excreted by the kidneys. Antipsychotics should be administered with caution to patients receiving anticonvulsant medication, with a history of seizures, or with EEG abnormalities, because they may lower the convulsive threshold. If indicated, adequate anticonvulsant therapy should be maintained concomitantly. Information for Patients Treatment with ORAP exposes the patient to serious risks. A decision to use ORAP chronically in Tourette’s Disorder is one that deserves full consideration by the patient (or patient’s family) as well as by the treating physician. Because the goal of treatment is symptomatic improvement, the patient’s view of the need for treatment and assessment of response are critical in evaluating the impact of therapy and weighing its benefits against the risks. Since the physician is the primary source of information about the use of a drug in any disease, it is recommended that the following information be discussed with patients and/or their families. ORAP is intended only for use in patients with Tourette’s Disorder whose symptoms are severe and who cannot tolerate, or who do not respond to HALDOL® (haloperidol). Given the likelihood that a proportion of patients exposed chronically to antipsychotics will develop tardive dyskinesia, it is advised that all patients in whom chronic use is contemplated be given, if possible, full information about this risk. The decision to inform patients and/or their guardians must obviously take into account the clinical circumstances and the competency of the patient to understand the information provided. There is limited information available on the use of ORAP in children under 12 years of age. Reference ID: 2870808 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda 7 The information available on ORAP from foreign marketing experience and from U.S. clinical trials indicates that ORAP has a side effect profile similar to that of other antipsychotic drugs. Patients should be informed that all types of side effects associated with the use of antipsychotics may be associated with the use of ORAP. In addition, sudden, unexpected deaths have occurred in patients taking high doses of ORAP for conditions other than Tourette’s Disorder. These deaths may have been the result of an effect of ORAP upon the heart. Therefore, patients should be instructed not to exceed the prescribed dose of ORAP and they should realize the need for the initial ECG and for follow-up ECGs during treatment. Also, pimozide, at a dose about 15 times that given humans, caused an increase in the number of benign tumors of the pituitary gland in female mice. It is not possible to say how important this is. Similar tumors were not seen in rats given pimozide, nor at lower doses in mice, which is reassuring. However, any such finding must be considered to suggest a possible risk of long term use of the drug. Because substances in grapefruit juice may inhibit the metabolism of pimozide by CYP 3A4, patients should be advised to avoid grapefruit juice. Laboratory Tests An ECG should be done at baseline and periodically thereafter throughout the period of dose adjustment. Any indication of prolongation of QTc interval beyond an absolute limit of 0.47 seconds (children) or 0.52 seconds (adults), or more than 25% above the patient’s original baseline should be considered a basis for stopping further dose increase (see CONTRAINDICATIONS) and considering a lower dose. Since hypokalemia has been associated with ventricular arrhythmias, potassium insufficiency, secondary to diuretics, diarrhea, or other cause, should be corrected before ORAP therapy is initiated and normal potassium maintained during therapy. Drug Interactions Because ORAP prolongs the QT interval of the electrocardiogram, an additive effect on QT interval would be anticipated if administered with other drugs, such as phenothiazines, tricyclic antidepressants or antiarrhythmic agents, which prolong the QT interval. Accordingly, pimozide should not be given with dofetilide, sotalol, quinidine, other Class Ia and III anti-arrhythmics, mesoridazine, thioridazine, chlorpromazine, droperidol, sparfloxacin, gatifloxacin, moxifloxacin, halofantrine, mefloquine, pentamidine, arsenic trioxide, levomethadyl acetate, dolasetron mesylate, probucol, tacrolimus, ziprasidone, or other drugs that have demonstrated QT prolongation as one of their pharmacodynamic effects. Also, the use of macrolide antibiotics in patients with prolonged QT intervals has been rarely associated with ventricular arrhythmias. Such concomitant administration should not be undertaken (see CONTRAINDICATIONS). Pimozide and Celexa – In a controlled study, a single dose of pimozide 2 mg co­ administered with racemic citalopram 40 mg given once daily for 11 days was associated with a mean increase in QTc values of approximately 10 msec compared to pimozide Reference ID: 2870808 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda 8 given alone. Racemic citalopram did not alter the mean AUC or Cmax of pimozide. The mechanism of this pharmacodynamic interaction is not known. Since ORAP is partly metabolized via CYP 3A4, it should not be administered concomitantly with inhibitors of this metabolic system, such as azole antifungal agents and protease inhibitor drugs (see CONTRAINDICATIONS). As CYP 1A2 may also contribute to the metabolism of ORAP, prescribers should be aware of the theoretical potential for drug interactions with inhibitors of this enzymatic system. ORAP may be capable of potentiating CNS depressants, including analgesics, sedatives, anxiolytics, and alcohol. Rare case reports have suggested possible additive effects of pimozide and fluoxetine leading to bradycardia. Concomitant administration of pimozide and sertraline should be contraindicated (See CONTRAINDICATIONS). Interaction with Food Patients should avoid grapefruit juice because it may inhibit the metabolism of pimozide by CYP 3A4. Carcinogenesis, Mutagenesis, Impairment of Fertility Carcinogenicity studies were conducted in mice and rats. In mice, pimozide causes a dose-related increase in pituitary and mammary tumors. When mice were treated for up to 18 months with pimozide, pituitary gland changes developed in females only. These changes were characterized as hyperplasia at doses approximating the human dose and adenoma at doses about fifteen times the maximum recommended human dose on a mg per kg basis. The mechanism for the induction of pituitary tumors in mice is not known. Mammary gland tumors in female mice were also increased, but these tumors are expected in rodents treated with antipsychotic drugs which elevate prolactin levels. Chronic administration of an antipsychotic also causes elevated prolactin levels in humans. Tissue culture experiments indicate that approximately one-third of human breast cancers are prolactin-dependent in vitro, a factor of potential importance if the prescription of these drugs is contemplated in a patient with a previously detected breast cancer. Although disturbances such as galactorrhea, amenorrhea, gynecomastia, and impotence have been reported with antipsychotic drugs, the clinical significance of elevated serum prolactin levels is unknown for most patients. Neither clinical studies nor epidemiologic studies conducted to date have shown an association between chronic administration of these drugs and mammary tumorigenesis. The available evidence, however, is considered too limited to be conclusive at this time. Reference ID: 2870808 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda 9 In a 24-month carcinogenicity study in rats, animals received up to 50 times the maximum recommended human dose. No increased incidence of overall tumors or tumors at any site was observed in either sex. Because of the limited number of animals surviving this study, the meaning of these results is unclear. Pimozide did not have mutagenic activity in the Ames test with four bacterial test strains, in the mouse dominant lethal test or in the micronucleus test in rats. Reproduction studies in animals were not adequate to assess all aspects of fertility. Nevertheless, female rats administered pimozide had prolonged estrus cycles, an effect also produced by other antipsychotic drugs. Pregnancy Category C. Reproduction studies performed in rats and rabbits at oral doses up to 8 times the maximum human dose did not reveal evidence of teratogenicity. In the rat, however, this multiple of the human dose resulted in decreased pregnancies and in the retarded development of fetuses. These effects are thought to be due to an inhibition or delay in implantation which is also observed in rodents administered other antipsychotic drugs. In the rabbit, maternal toxicity, mortality, decreased weight gain, and embryotoxicity including increased resorptions were dose-related. Because animal reproduction studies are not always predictive of human response, pimozide should be given to a pregnant woman only if the potential benefits of treatment clearly outweigh the potential risks. Nonteratogenic effects. Neonates exposed to antipsychotic drugs, during the third trimester of pregnancy are at risk for extrapyramidal and/or withdrawal symptoms following delivery. There have been reports of agitation, hypertonia, hypotonia, tremor, somnolence, respiratory distress and feeding disorder in these neonates. These complications have varied in severity; while in some cases symptoms have been self- limited, in other cases neonates have required intensive care unit support and prolonged hospitalization. ORAP should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus. Labor and Delivery This drug has no recognized use in labor or delivery. Nursing Mothers It is not known whether pimozide is excreted in human milk. Because many drugs are excreted in human milk and because of the potential for tumorigenicity and unknown cardiovascular effects in the infant, a decision should be made whether to discontinue nursing or to discontinue the drug, taking into account the importance of the drug to the mother. Pediatric Use Reference ID: 2870808 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda 10 Although Tourette's Disorder most often has its onset between the ages of 2 and 15 years, information on the use and efficacy of ORAP in patients less than 12 years of age is limited. A 24-week open label study in 36 children between the ages of 2 and 12 demonstrated that pimozide has a similar safety profile in this age group as in older patients and there were no safety findings that would preclude its use in this age group. Because its use and safety have not been evaluated in other childhood disorders, ORAP is not recommended for use in any condition other than Tourette’s Disorder. ADVERSE REACTIONS General Extrapyramidal Reactions: Neuromuscular (extrapyramidal) reactions during the administration of ORAP ® (pimozide) have been reported frequently, often during the first few days of treatment. In most patients, these reactions involved Parkinson-like symptoms which, when first observed, were usually mild to moderately severe and usually reversible. Other types of neuromuscular reactions (motor restlessness, dystonia, akathisia, hyperreflexia, opisthotonos, oculogyric crises) have been reported far less frequently. Severe extrapyramidal reactions have been reported to occur at relatively low doses. Generally the occurrence and severity of most extrapyramidal symptoms are dose-related since they occur at relatively high doses and have been shown to disappear or become less severe when the dose is reduced. Administration of antiparkinson drugs such as benztropine mesylate or trihexyphenidyl hydrochloride may be required for control of such reactions. It should be noted that persistent extrapyramidal reactions have been reported and that the drug may have to be discontinued in such cases. Withdrawal Emergent Neurological Signs: Generally, patients receiving short term therapy experience no problems with abrupt discontinuation of antipsychotic drugs. However, some patients on maintenance treatment experience transient dyskinetic signs after abrupt withdrawal. In certain of these cases the dyskinetic movements are indistinguishable from the syndrome described below under “Tardive Dyskinesia” except for duration. It is not known whether gradual withdrawal of antipsychotic drugs will reduce the rate of occurrence of withdrawal emergent neurological signs, but until further evidence becomes available, it seems reasonable to gradually withdraw use of ORAP. Tardive Dyskinesia: ORAP may be associated with persistent dyskinesias. Tardive dyskinesia, a syndrome consisting of potentially irreversible, involuntary, dyskinetic movements, may appear in some patients on long-term therapy or may occur after drug therapy has been discontinued. The risk appears to be greater in elderly patients on high- dose therapy, especially females. The symptoms are persistent and in some patients appear irreversible. The syndrome is characterized by rhythmical involuntary movements of tongue, face, mouth or jaw (e.g., protrusion of tongue, puffing of cheeks, puckering of mouth, chewing movements). Sometimes these may be accompanied by involuntary movements of extremities and the trunk. Reference ID: 2870808 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda 11 There is no known effective treatment for tardive dyskinesia; antiparkinson agents usually do not alleviate the symptoms of this syndrome. It is suggested that all antipsychotic agents be discontinued if these symptoms appear. Should it be necessary to reinstitute treatment, or increase the dosage of the agent, or switch to a different antipsychotic agent, this syndrome may be masked. It has been reported that fine vermicular movement of the tongue may be an early sign of tardive dyskinesia and if the medication is stopped at that time the syndrome may not develop. Electrocardiographic Changes: Electrocardiographic changes have been observed in clinical trials of ORAP in Tourette’s Disorder and schizophrenia. These have included prolongation of the QT interval, flattening, notching and inversion of the T wave and the appearance of U waves. Sudden, unexpected deaths and grand mal seizure have occurred at doses above 20 mg/day. Neuroleptic Malignant Syndrome: Neuroleptic malignant syndrome (NMS) has been reported with ORAP. (See WARNINGS for further information concerning NMS.) Hyperpyrexia: Hyperpyrexia has been reported with other antipsychotic drugs.

These reports do not provide sufficient information to establish a clear causal relationship with the use of ORAP. Gastrointestinal: Gingival hyperplasia in one patient Hematologic: Hemolytic anemia Metabolic/Nutritional: Hyponatremia Other: Seizure OVERDOSAGE In general, the signs and symptoms of overdosage with ORAP (pimozide) would be an exaggeration of known pharmacologic effects and adverse reactions, the most prominent of which would be: 1) electrocardiographic abnormalities, 2) severe extrapyramidal reactions, 3) hypotension, 4) a comatose state with respiratory depression. In the event of overdosage, gastric lavage, establishment of a patent airway and, if necessary, mechanically-assisted respiration are advised. Electrocardiographic monitoring should commence immediately and continue until the ECG parameters are within the normal range. Hypotension and circulatory collapse may be counteracted by use of intravenous fluids, plasma, or concentrated albumin, and vasopressor agents such as metaraminol, phenylephrine and norepinephrine. Epinephrine should not be used. In case of severe extrapyramidal reactions, antiparkinson medication should be administered. Because of the long half-life of Reference ID: 2870808 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda 15 pimozide, patients who take an overdose should be observed for at least 4 days. As with all drugs, the physician should consider contacting a poison control center for additional information on the treatment of overdose. DOSAGE AND ADMINISTRATION General The suppression of tics by ORAP requires a slow and gradual introduction of the drug. The patient’s dose should be carefully adjusted to a point where the suppression of tics and the relief afforded is balanced against the untoward side effects of the drug. An ECG should be done at baseline and periodically thereafter, especially during the period of dose adjustment (see WARNINGS and PRECAUTIONS - Laboratory Tests). Periodic attempts should be made to reduce the dosage of ORAP to see whether or not tics persist at the level and extent first identified. In attempts to reduce the dosage of ORAP, consideration should be given to the possibility that increases of tic intensity and frequency may represent a transient, withdrawal-related phenomenon rather than a return of disease symptoms. Specifically, one to two weeks should be allowed to elapse before one concludes that an increase in tic manifestations is a function of the underlying disease syndrome rather than a response to drug withdrawal. A gradual withdrawal is recommended in any case. Children Reliable dose response data for the effects of ORAP (pimozide) on tic manifestation in Tourette’s Disorder patients below the age of twelve are not available. Treatment should be initiated at a dose of 0.05 mg/kg preferably taken once at bedtime. The dose may be increased every third day to a maximum of 0.2 mg/kg not to exceed 10 mg/day. Adults In general, treatment with ORAP should be initiated with a dose of 1 to 2 mg a day in divided doses. The dose may be increased thereafter every other day. Most patients are maintained at less than 0.2 mg/kg per day, or 10 mg/day, whichever is less. Doses greater than 0.2 mg/kg/day or 10 mg/day are not recommended. ANIMAL PHARMACOLOGY A chronic study in dogs indicated that pimozide caused gingival hyperplasia when administered for several months at about 5 times the maximum recommended human dose. This condition was reversible after withdrawal. HOW SUPPLIED ORAP® (pimozide) 1 mg tablets are white, oval, scored tablets, debossed “ORAP 1”. They are available in bottles of 100 (NDC 57844-151-01).

1 XXXXXX ORAP® (Pimozide) Tablets GATE 151 187 DESCRIPTION ORAP ® (pimozide) is an orally active antipsychotic agent of the diphenyl-butylpiperidine series. The structural formula of pimozide, 1-[1-[4,4-bis(4-fluorophenyl) butyl]-4­ piperidinyl]-1,3-dihydro-2H-benzimidazole-2-one is: structural formula The solubility of pimozide in water is less than 0.01 mg/mL; it is slightly soluble in most organic solvents. Each white ORAP tablet contains either 1 mg or 2 mg of pimozide and the following inactive ingredients: calcium stearate, microcrystalline cellulose, lactose anhydrous and corn starch. CLINICAL PHARMACOLOGY Pharmacodynamic Actions ORAP (pimozide) is an orally active antipsychotic drug product which shares with other antipsychotics the ability to blockade dopaminergic receptors on neurons in the central nervous system. Although its exact mode of action has not been established, the ability of pimozide to suppress motor and phonic tics in Tourette’s Disorder is thought to be a function of its dopaminergic blocking activity. However, receptor blockade is often accompanied by a series of secondary alterations in central dopamine metabolism and function which may contribute to both pimozide’s therapeutic and untoward effects. In addition, pimozide, in common with other antipsychotic drugs, has various effects on other central nervous system receptor systems which are not fully characterized. Metabolism and Pharmacokinetics More than 50% of a dose of pimozide is absorbed after oral administration. Based on the pharmacokinetic and metabolic profile, pimozide appears to undergo significant first pass Reference ID: 3020950 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda 2 metabolism. Peak serum levels occur generally six to eight hours (range 4-12 hours) after dosing. Pimozide is extensively metabolized, primarily by N-dealkylation in the liver. This metabolism is catalyzed mainly by the cytochrome P450 3A4 (CYP 3A4) enzymatic system and to a lesser extent, by cytochrome P450 1A2 (CYP 1A2) and cytochrome P450 2D6 (CYP 2D6). Two major metabolites have been identified, 1-(4-piperidyl)-2­ benzimidazolinone and 4,4-bis(4-fluorophenyl) butyric acid. The antipsychotic activity of these metabolites is undetermined. The major route of elimination of pimozide and its metabolites is through the kidney. The mean serum elimination half-life of pimozide in schizophrenic patients was approximately 55 hours. There was a 13-fold interindividual difference in the area under the serum pimozide level-time curve and an equivalent degree of variation in peak serum levels among patients studied. The significance of this is unclear since there are few correlations between plasma levels and clinical findings. Effects of food and disease upon the absorption, distribution, metabolism and elimination of pimozide are not known. Effects of concomitant medication and genetic variations on pimozide metabolism are described in the CONTRAINDICATIONS and PRECAUTIONS sections. INDICATIONS AND USAGE ORAP (pimozide) is indicated for the suppression of motor and phonic tics in patients with Tourette’s Disorder who have failed to respond satisfactorily to standard treatment. ORAP is not intended as a treatment of first choice nor is it intended for the treatment of tics that are merely annoying or cosmetically troublesome. ORAP should be reserved for use in Tourette’s Disorder patients whose development and/or daily life function is severely compromised by the presence of motor and phonic tics. Evidence supporting approval of pimozide for use in Tourette’s Disorder was obtained in two controlled clinical investigations which enrolled patients between the ages of 8 and 53 years. Most subjects in the two trials were 12 or older. CONTRAINDICATIONS 1. ORAP (pimozide) is contraindicated in the treatment of simple tics or tics other than those associated with Tourette’s Disorder. 2. ORAP should not be used in patients taking drugs that may, themselves, cause motor and phonic tics (e.g., pemoline, methylphenidate and amphetamines) until such patients have been withdrawn from these drugs to determine whether or not the drugs, rather than Tourette’s Disorder, are responsible for the tics. 3. Because ORAP prolongs the QT interval of the electrocardiogram it is contraindicated in patients with congenital long QT syndrome, patients with a history of cardiac arrhythmias, patients taking other drugs which prolong the QT interval of the Reference ID: 3020950 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda 3 electrocardiogram or patients with known hypokalemia or hypomagnesemia (see also PRECAUTIONS - Drug Interactions). 4. ORAP is contraindicated in patients with severe toxic central nervous system depression or comatose states from any cause. 5. ORAP is contraindicated in patients with hypersensitivity to it. As it is not known whether cross-sensitivity exists among the antipsychotics, pimozide should be used with appropriate caution in patients who have demonstrated hypersensitivity to other antipsychotic drugs. 6. Ventricular arrhythmias have been rarely associated with the use of macrolide antibiotics in patients with prolonged QT intervals, as might be produced by ORAP. Specifically, two sudden deaths have been reported when clarithromycin was added to ongoing pimozide therapy. Furthermore, some evidence suggests that pimozide is metabolized partly by the enzyme system cytochrome P450 3A4 (CYP 3A4). Macrolide antibiotics are inhibitors of CYP 3A4, and thus could potentially impede pimozide metabolism. For these reasons, ORAP is contraindicated in patients receiving the macrolide antibiotics clarithromycin, erythromycin, azithromycin, dirithromycin, and troleandomycin. 7. Concomitant use in patients taking Celexa or Lexapro is contraindicated (see Precautions - Drug Interactions - Pimozide and Celexa). 8. Clinical drug interaction studies have demonstrated that pimozide is also metabolized by CYP 2D6. Concomitant use of ORAP with paroxetine and other strong CYP 2D6 inhibitors is contraindicated (See PRECAUTIONS – Drug Interactions). 9. Concomitant use of pimozide in patients taking sertraline is contraindicated (See PRECAUTIONS – Drug Interactions). Because azole antifungal agents are also inhibitors of the CYP 3A4 enzymes and thus may likewise impair pimozide metabolism, ORAP is contraindicated in patients receiving the azole antifungal agents itraconazole and ketoconazole. Similarly, protease inhibitor drugs are also inhibitors of CYP 3A4, and thus ORAP is contraindicated in patients receiving protease inhibitors such as ritonavir, saquinovir, indinavir, and nelfinavir. (See PRECAUTIONS - Drug Interactions.) Nefazodone is a potent inhibitor of CYP 3A4, and its concomitant use with ORAP is also contraindicated. Other drugs that are relatively less potent inhibitors of CYP 3A4 should also be avoided, in view of the risks: e.g. zileuton, fluvoxamine. WARNINGS Reference ID: 3020950 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda 4 The use of ORAP (pimozide) in the treatment of Tourette’s Disorder involves different risk/benefit considerations than when antipsychotic drugs are used to treat other conditions. Consequently, a decision to use ORAP should take into consideration the following (see also PRECAUTIONS - Information for Patients). Tardive Dyskinesia A syndrome consisting of potentially irreversible, involuntary, dyskinetic movements may develop in patients treated with antipsychotic drugs. Although the prevalence of the syndrome appears to be highest among the elderly, especially elderly women, it is impossible to rely upon prevalence estimates to predict, at the inception of antipsychotic treatment, which patients are likely to develop the syndrome. Whether antipsychotic drug products differ in their potential to cause tardive dyskinesia is unknown. Both the risk of developing tardive dyskinesia and the likelihood that it will become irreversible are believed to increase as the duration of treatment and the total cumulative dose of antipsychotic drugs administered to the patient increase. However, the syndrome can develop, although much less commonly, after relatively brief treatment periods at low doses. There is no known treatment for established cases of tardive dyskinesia, although the syndrome may remit, partially or completely, if antipsychotic treatment is withdrawn. Antipsychotic treatment itself, however, may suppress (or partially suppress) the signs and symptoms of the syndrome and thereby may possibly mask the underlying process. The effect that symptomatic suppression has upon the long-term course of the syndrome is unknown. Given these considerations, antipsychotic drugs should be prescribed in a manner that is most likely to minimize the occurrence of tardive dyskinesia. Chronic antipsychotic treatment should generally be reserved for patients who suffer from a chronic illness that, 1) is known to respond to antipsychotic drugs, and, 2) for whom alternative, equally effective, but potentially less harmful treatments are not available or appropriate. In patients who do require chronic treatment, the smallest dose and the shortest duration of treatment producing a satisfactory clinical response should be sought. The need for continued treatment should be reassessed periodically. If signs and symptoms of tardive dyskinesia appear in a patient on antipsychotics, drug discontinuation should be considered. However, some patients may require treatment despite the presence of the syndrome. (For further information about the description of tardive dyskinesia and its clinical detection, please refer to ADVERSE REACTIONS and PRECAUTIONS - Information for Patients.) Neuroleptic Malignant Syndrome (NMS) A potentially fatal symptom complex sometimes referred to as Neuroleptic Malignant Syndrome (NMS) has been reported in association with antipsychotic drugs. Clinical manifestations of NMS are hyperpyrexia, muscle rigidity, altered mental status (including Reference ID: 3020950 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda 5 catatonic signs) and evidence of autonomic instability (irregular pulse or blood pressure, tachycardia, diaphoresis, and cardiac dysrhythmias). Additional signs may include elevated creatine phosphokinase, myoglobinuria (rhabdomyolysis) and acute renal failure. The diagnostic evaluation of patients with this syndrome is complicated. In arriving at a diagnosis, it is important to identify cases where the clinical presentation includes both serious medical illness (e.g., pneumonia, systemic infection, etc.) and untreated or inadequately treated extrapyramidal signs and symptoms (EPS). Other important considerations in the differential diagnosis include central anticholinergic toxicity, heat stroke, drug fever and primary central nervous system (CNS) pathology. The management of NMS should include 1) immediate discontinuation of antipsychotic drugs and other drugs not essential to concurrent therapy, 2) intensive symptomatic treatment and medical monitoring, and 3) treatment of any concomitant serious medical problems for which specific treatments are available. There is no general agreement about specific pharmacological treatment regimens for uncomplicated NMS. If a patient requires antipsychotic drug treatment after recovery from NMS, the potential reintroduction of drug therapy should be carefully considered. The patient should be carefully monitored, since recurrences of NMS have been reported. Hyperpyrexia, not associated with the above symptom complex, has been reported with other antipsychotic drugs. Other Sudden, unexpected deaths have occurred in experimental studies of conditions other than Tourette’s Disorder. These deaths occurred while patients were receiving dosages in the range of 1 mg per kg. One possible mechanism for such deaths is prolongation of the QT interval predisposing patients to ventricular arrhythmia. An electrocardiogram should be performed before ORAP treatment is initiated and periodically thereafter, especially during the period of dose adjustment. ORAP may have a tumorigenic potential. Based on studies conducted in mice, it is known that pimozide can produce a dose-related increase in pituitary tumors. The full significance of this finding is not known, but should be taken into consideration in the physician’s and patient’s decisions to use this drug product. This finding should be given special consideration when the patient is young and chronic use of pimozide is anticipated (see PRECAUTIONS - Carcinogenesis, Mutagenesis, Impairment of Fertility). PRECAUTIONS Leukopenia, Neutropenia and Agranulocytosis Class Effect: In clinical trial and/or postmarketing experience, events of leukopenia/neutropenia and agranulocytosis have been reported temporally related to antipsychotic agents. Reference ID: 3020950 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda 6 Possible risk factors for leukopenia/neutropenia include preexisting low white blood cell count (WBC) and history of drug induced leukopenia/neutropenia. Patients with a history of a clinically significant low WBC or drug induced leukopenia/neutropenia should have their complete blood count (CBC) monitored frequently during the first few months of therapy and discontinuation of ORAP should be considered at the first sign of a clinically significant decline in WBC in the absence of other causative factors. Patients with clinically significant neutropenia should be carefully monitored for fever or other symptoms or signs of infection and treated promptly if such symptoms or signs occur. Patients with severe neutropenia (absolute neutrophil count <1000/mm3) should discontinue ORAP and have their WBC followed until recovery. General ORAP (pimozide) may impair the mental and/or physical abilities required for the performance of potentially hazardous tasks, such as driving a car or operating machinery, especially during the first few days of therapy. ORAP produces anticholinergic side effects and should be used with caution in individuals whose conditions may be aggravated by anticholinergic activity. ORAP should be administered cautiously to patients with impairment of liver or kidney function, because it is metabolized by the liver and excreted by the kidneys. Antipsychotics should be administered with caution to patients receiving anticonvulsant medication, with a history of seizures, or with EEG abnormalities, because they may lower the convulsive threshold. If indicated, adequate anticonvulsant therapy should be maintained concomitantly. Information for Patients Treatment with ORAP exposes the patient to serious risks. A decision to use ORAP chronically in Tourette’s Disorder is one that deserves full consideration by the patient (or patient’s family) as well as by the treating physician. Because the goal of treatment is symptomatic improvement, the patient’s view of the need for treatment and assessment of response are critical in evaluating the impact of therapy and weighing its benefits against the risks. Since the physician is the primary source of information about the use of a drug in any disease, it is recommended that the following information be discussed with patients and/or their families. ORAP is intended only for use in patients with Tourette’s Disorder whose symptoms are severe and who cannot tolerate, or who do not respond to HALDOL® (haloperidol). Given the likelihood that a proportion of patients exposed chronically to antipsychotics will develop tardive dyskinesia, it is advised that all patients in whom chronic use is contemplated be given, if possible, full information about this risk. The decision to inform patients and/or their guardians must obviously take into account the clinical circumstances and the competency of the patient to understand the information provided. Reference ID: 3020950 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda 7 There is limited information available on the use of ORAP in children under 12 years of age. The information available on ORAP from foreign marketing experience and from U.S. clinical trials indicates that ORAP has a side effect profile similar to that of other antipsychotic drugs. Patients should be informed that all types of side effects associated with the use of antipsychotics may be associated with the use of ORAP. In addition, sudden, unexpected deaths have occurred in patients taking high doses of ORAP for conditions other than Tourette’s Disorder. These deaths may have been the result of an effect of ORAP upon the heart. Therefore, patients should be instructed not to exceed the prescribed dose of ORAP and they should realize the need for the initial ECG and for follow-up ECGs during treatment. Also, pimozide, at a dose about 15 times that given humans, caused an increase in the number of benign tumors of the pituitary gland in female mice. It is not possible to say how important this is. Similar tumors were not seen in rats given pimozide, nor at lower doses in mice, which is reassuring. However, any such finding must be considered to suggest a possible risk of long term use of the drug. Because substances in grapefruit juice may inhibit the metabolism of pimozide by CYP 3A4, patients should be advised to avoid grapefruit juice. Laboratory Tests An ECG should be done at baseline and periodically thereafter throughout the period of dose adjustment. Any indication of prolongation of QTc interval beyond an absolute limit of 0.47 seconds (children) or 0.52 seconds (adults), or more than 25% above the patient’s original baseline should be considered a basis for stopping further dose increase (see CONTRAINDICATIONS) and considering a lower dose. Since hypokalemia has been associated with ventricular arrhythmias, potassium insufficiency, secondary to diuretics, diarrhea, or other cause, should be corrected before ORAP therapy is initiated and normal potassium maintained during therapy. Drug Interactions Because ORAP prolongs the QT interval of the electrocardiogram, an additive effect on QT interval would be anticipated if administered with other drugs, such as phenothiazines, tricyclic antidepressants or antiarrhythmic agents, which prolong the QT interval. Accordingly, pimozide should not be given with dofetilide, sotalol, quinidine, other Class Ia and III anti-arrhythmics, mesoridazine, thioridazine, chlorpromazine, droperidol, sparfloxacin, gatifloxacin, moxifloxacin, halofantrine, mefloquine, pentamidine, arsenic trioxide, levomethadyl acetate, dolasetron mesylate, probucol, tacrolimus, ziprasidone, or other drugs that have demonstrated QT prolongation as one of their pharmacodynamic effects. Also, the use of macrolide antibiotics in patients with prolonged QT intervals has been rarely associated with ventricular arrhythmias. Such concomitant administration should not be undertaken (see CONTRAINDICATIONS). Reference ID: 3020950 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda 8 Since ORAP is partly metabolized via CYP 3A4, it should not be administered concomitantly with inhibitors of this metabolic system, such as azole antifungal agents and protease inhibitor drugs (see CONTRAINDICATIONS). Pimozide and Celexa: In a controlled study, a single dose of pimozide 2 mg co­ administered with racemic citalopram 40 mg given once daily for 11 days was associated with a mean increase in QTc values of approximately 10 msec compared to pimozide given alone. Racemic citalopram did not alter the mean AUC or Cmax of pimozide. The mechanism of this pharmacodynamic interaction is not known. Concomitant use of pimozide and Celexa or Lexapro is contraindicated (See CONTRAINDICATIONS). CYP 2D6 inhibitors: In healthy subjects, co-administration of pimozide 2 mg (single dose) and paroxetine 60 mg resulted in a 151% increase in pimozide AUC and a 62% increase in pimozide Cmax compared to pimozide administered alone. The increase in pimozide AUC and Cmax is related to the CYP 2D6 inhibitory properties of paroxetine. Concomitant use of pimozide and paroxetine or other strong CYP 2D6 inhibitors are contraindicated (see CONTRAINDICATIONS). As CYP 1A2 may also contribute to the metabolism of ORAP, prescribers should be aware of the theoretical potential for drug interactions with inhibitors of this enzymatic system. ORAP may be capable of potentiating CNS depressants, including analgesics, sedatives, anxiolytics, and alcohol. Rare case reports have suggested possible additive effects of pimozide and fluoxetine leading to bradycardia. Concomitant administration of pimozide and sertraline should be contraindicated (See CONTRAINDICATIONS). PharmacogenomicsIndividuals with genetic variations resulting in poor CYP 2D6 metabolism (approximately 5 to 10% of the population) exhibit higher pimozide concentrations than extensive CYP 2D6 metabolizers. The concentrations observed in poor CYP 2D6 metabolizers are similar to those seen with strong CYP 2D6 inhibitors such as paroxetine. The time to achieve steady state pimozide concentrations is expected to be longer (approximately 2 weeks) in poor CYP 2D6 metabolizers because of the prolonged half-life. Alternative dosing strategies are recommended in patients who are genetically poor CYP 2D6 metabolizers (see DOSAGE and ADMINISTRATION). Interaction with Food Patients should avoid grapefruit juice because it may inhibit the metabolism of pimozide by CYP 3A4. Carcinogenesis, Mutagenesis, Impairment of Fertility Carcinogenicity studies were conducted in mice and rats. In mice, pimozide causes a dose-related increase in pituitary and mammary tumors. Reference ID: 3020950 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda 9 When mice were treated for up to 18 months with pimozide, pituitary gland changes developed in females only. These changes were characterized as hyperplasia at doses approximating the human dose and adenoma at doses about fifteen times the maximum recommended human dose on a mg per kg basis. The mechanism for the induction of pituitary tumors in mice is not known. Mammary gland tumors in female mice were also increased, but these tumors are expected in rodents treated with antipsychotic drugs which elevate prolactin levels. Chronic administration of an antipsychotic also causes elevated prolactin levels in humans. Tissue culture experiments indicate that approximately one-third of human breast cancers are prolactin-dependent in vitro, a factor of potential importance if the prescription of these drugs is contemplated in a patient with a previously detected breast cancer. Although disturbances such as galactorrhea, amenorrhea, gynecomastia, and impotence have been reported with antipsychotic drugs, the clinical significance of elevated serum prolactin levels is unknown for most patients. Neither clinical studies nor epidemiologic studies conducted to date have shown an association between chronic administration of these drugs and mammary tumorigenesis. The available evidence, however, is considered too limited to be conclusive at this time. In a 24-month carcinogenicity study in rats, animals received up to 50 times the maximum recommended human dose. No increased incidence of overall tumors or tumors at any site was observed in either sex. Because of the limited number of animals surviving this study, the meaning of these results is unclear. Pimozide did not have mutagenic activity in the Ames test with four bacterial test strains, in the mouse dominant lethal test or in the micronucleus test in rats. Reproduction studies in animals were not adequate to assess all aspects of fertility. Nevertheless, female rats administered pimozide had prolonged estrus cycles, an effect also produced by other antipsychotic drugs. Pregnancy Category C. Reproduction studies performed in rats and rabbits at oral doses up to 8 times the maximum human dose did not reveal evidence of teratogenicity. In the rat, however, this multiple of the human dose resulted in decreased pregnancies and in the retarded development of fetuses. These effects are thought to be due to an inhibition or delay in implantation which is also observed in rodents administered other antipsychotic drugs. In the rabbit, maternal toxicity, mortality, decreased weight gain, and embryotoxicity including increased resorptions were dose-related. Because animal reproduction studies are not always predictive of human response, pimozide should be given to a pregnant woman only if the potential benefits of treatment clearly outweigh the potential risks. Nonteratogenic effects. Neonates exposed to antipsychotic drugs, during the third trimester of pregnancy are at risk for extrapyramidal and/or withdrawal symptoms following delivery. There have been reports of agitation, hypertonia, hypotonia, tremor, somnolence, respiratory distress and feeding disorder in these neonates. These Reference ID: 3020950 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda 10 complications have varied in severity; while in some cases symptoms have been self- limited, in other cases neonates have required intensive care unit support and prolonged hospitalization. ORAP should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus. Labor and Delivery This drug has no recognized use in labor or delivery. Nursing Mothers It is not known whether pimozide is excreted in human milk. Because many drugs are excreted in human milk and because of the potential for tumorigenicity and unknown cardiovascular effects in the infant, a decision should be made whether to discontinue nursing or to discontinue the drug, taking into account the importance of the drug to the mother. Pediatric Use Although Tourette's Disorder most often has its onset between the ages of 2 and 15 years, information on the use and efficacy of ORAP in patients less than 12 years of age is limited. A 24-week open label study in 36 children between the ages of 2 and 12 demonstrated that pimozide has a similar safety profile in this age group as in older patients and there were no safety findings that would preclude its use in this age group. Because its use and safety have not been evaluated in other childhood disorders, ORAP is not recommended for use in any condition other than Tourette’s Disorder. ADVERSE REACTIONS General Extrapyramidal Reactions: Neuromuscular (extrapyramidal) reactions during the administration of ORAP ® (pimozide) have been reported frequently, often during the first few days of treatment. In most patients, these reactions involved Parkinson-like symptoms which, when first observed, were usually mild to moderately severe and usually reversible. Other types of neuromuscular reactions (motor restlessness, dystonia, akathisia, hyperreflexia, opisthotonos, oculogyric crises) have been reported far less frequently. Severe extrapyramidal reactions have been reported to occur at relatively low doses. Generally the occurrence and severity of most extrapyramidal symptoms are dose-related since they occur at relatively high doses and have been shown to disappear or become less severe when the dose is reduced. Administration of antiparkinson drugs such as benztropine mesylate or trihexyphenidyl hydrochloride may be required for control of such reactions. It should be noted that persistent extrapyramidal reactions have been reported and that the drug may have to be discontinued in such cases. Withdrawal Emergent Neurological Signs: Generally, patients receiving short term therapy experience no problems with abrupt discontinuation of antipsychotic drugs. Reference ID: 3020950 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda 11 However, some patients on maintenance treatment experience transient dyskinetic signs after abrupt withdrawal. In certain of these cases the dyskinetic movements are indistinguishable from the syndrome described below under “Tardive Dyskinesia” except for duration. It is not known whether gradual withdrawal of antipsychotic drugs will reduce the rate of occurrence of withdrawal emergent neurological signs, but until further evidence becomes available, it seems reasonable to gradually withdraw use of ORAP. Tardive Dyskinesia: ORAP may be associated with persistent dyskinesias. Tardive dyskinesia, a syndrome consisting of potentially irreversible, involuntary, dyskinetic movements, may appear in some patients on long-term therapy or may occur after drug therapy has been discontinued. The risk appears to be greater in elderly patients on high- dose therapy, especially females. The symptoms are persistent and in some patients appear irreversible. The syndrome is characterized by rhythmical involuntary movements of tongue, face, mouth or jaw (e.g., protrusion of tongue, puffing of cheeks, puckering of mouth, chewing movements). Sometimes these may be accompanied by involuntary movements of extremities and the trunk. There is no known effective treatment for tardive dyskinesia; antiparkinson agents usually do not alleviate the symptoms of this syndrome. It is suggested that all antipsychotic agents be discontinued if these symptoms appear. Should it be necessary to reinstitute treatment, or increase the dosage of the agent, or switch to a different antipsychotic agent, this syndrome may be masked. It has been reported that fine vermicular movement of the tongue may be an early sign of tardive dyskinesia and if the medication is stopped at that time the syndrome may not develop. Electrocardiographic Changes: Electrocardiographic changes have been observed in clinical trials of ORAP in Tourette’s Disorder and schizophrenia. These have included prolongation of the QT interval, flattening, notching and inversion of the T wave and the appearance of U waves. Sudden, unexpected deaths and grand mal seizure have occurred at doses above 20 mg/day. Neuroleptic Malignant Syndrome: Neuroleptic malignant syndrome (NMS) has been reported with ORAP. (See WARNINGS for further information concerning NMS.) Hyperpyrexia: Hyperpyrexia has been reported with other antipsychotic drugs.

The physician should consider that other adverse reactions associated with antipsychotics may occur. Other Adverse Reactions In addition to the adverse reactions listed above, those listed below have been reported in U.S. clinical trials of ORAP in conditions other than Tourette’s Disorder. Body as a Whole: Asthenia, chest pain, periorbital edema Cardiovascular/Respiratory: Postural hypotension, hypotension, hypertension, tachycardia, palpitations Gastrointestinal: Increased salivation, nausea, vomiting, anorexia, GI distress Endocrine: Loss of libido Metabolic/Nutritional: Weight gain, weight loss Central Nervous System: Dizziness, tremor, parkinsonism, fainting, dyskinesia Psychiatric: Excitement Skin: Rash, sweating, skin irritation Special Senses: Blurred vision, cataracts Urogenital: Nocturia, urinary frequency Postmarketing Reports The following experiences were described in spontaneous postmarketing reports. These reports do not provide sufficient information to establish a clear causal relationship with the use of ORAP. Gastrointestinal: Gingival hyperplasia in one patient Hematologic: Hemolytic anemia Metabolic/Nutritional: Hyponatremia Reference ID: 3020950 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda 15 Other: Seizure OVERDOSAGE In general, the signs and symptoms of overdosage with ORAP (pimozide) would be an exaggeration of known pharmacologic effects and adverse reactions, the most prominent of which would be: 1) electrocardiographic abnormalities, 2) severe extrapyramidal reactions, 3) hypotension, 4) a comatose state with respiratory depression. In the event of overdosage, gastric lavage, establishment of a patent airway and, if necessary, mechanically-assisted respiration are advised. Electrocardiographic monitoring should commence immediately and continue until the ECG parameters are within the normal range. Hypotension and circulatory collapse may be counteracted by use of intravenous fluids, plasma, or concentrated albumin, and vasopressor agents such as metaraminol, phenylephrine and norepinephrine. Epinephrine should not be used. In case of severe extrapyramidal reactions, antiparkinson medication should be administered. Because of the long half-life of pimozide, patients who take an overdose should be observed for at least 4 days. As with all drugs, the physician should consider contacting a poison control center for additional information on the treatment of overdose. DOSAGE AND ADMINISTRATION General The suppression of tics by ORAP requires a slow and gradual introduction of the drug. The patient’s dose should be carefully adjusted to a point where the suppression of tics and the relief afforded is balanced against the untoward side effects of the drug. An ECG should be done at baseline and periodically thereafter, especially during the period of dose adjustment (see WARNINGS and PRECAUTIONS - Laboratory Tests). Periodic attempts should be made to reduce the dosage of ORAP to see whether or not tics persist at the level and extent first identified. In attempts to reduce the dosage of ORAP, consideration should be given to the possibility that increases of tic intensity and frequency may represent a transient, withdrawal-related phenomenon rather than a return of disease symptoms. Specifically, one to two weeks should be allowed to elapse before one concludes that an increase in tic manifestations is a function of the underlying disease syndrome rather than a response to drug withdrawal. A gradual withdrawal is recommended in any case. Children Reliable dose response data for the effects of ORAP (pimozide) on tic manifestation in Tourette’s Disorder patients below the age of twelve are not available. Treatment should be initiated at a dose of 0.05 mg/kg preferably taken once at bedtime. The dose may be increased every third day to a maximum of 0.2 mg/kg not to exceed 10 mg/day. Reference ID: 3020950 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda 16 At doses above 0.05 mg/kg/day, CYP 2D6 genotyping should be performed. In poor CYP 2D6 metabolizers, ORAP doses should not exceed 0.05 mg/kg/day, and doses should not be increased earlier than 14 days (see PRECAUTIONS – Pharmacogenomics). Adults In general, treatment with ORAP should be initiated with a dose of 1 to 2 mg a day in divided doses. The dose may be increased thereafter every other day. Most patients are maintained at less than 0.2 mg/kg/day, or 10 mg/day, whichever is less. Doses greater than 0.2 mg/kg/day or 10 mg/day are not recommended. At doses above 4 mg/day, CYP 2D6 genotyping should be performed. In poor CYP 2D6 metabolizers, ORAP doses should not exceed 4 mg/day, and doses should not be increased earlier than 14 days (see PRECAUTIONS – Pharmacogenomics). ANIMAL PHARMACOLOGY A chronic study in dogs indicated that pimozide caused gingival hyperplasia when administered for several months at about 5 times the maximum recommended human dose. This condition was reversible after withdrawal. HOW SUPPLIED ORAP® (pimozide) 1 mg tablets are white, oval, scored tablets, debossed “ORAP 1”. They are available in bottles of 100 (NDC 57844-151-01).

DIANEAL PD-2 Peritoneal Dialysis Solution AMBU-FLEX Container For Peritoneal Dialysis For intraperitoneal administration only Description DIANEAL PD-2 peritoneal dialysis solutions in AMBU-FLEX containers are sterile, nonpyrogenic solutions for intraperitoneal administration only. They contain no bacteriostatic or antimicrobial agents or added buffers. Composition, calculated osmolarity, pH, and ionic concentrations are shown in Table 1. Potassium is omitted from DIANEAL solutions because dialysis may be performed to correct hyperkalemia. In situations in which there is a normal serum potassium level or hypokalemia, the addition of potassium chloride (up to a concentration of 4 mEq/L) may be indicated to prevent severe hypokalemia. Addition of potassium chloride should be made after careful evaluation of serum and total body potassium and only under the direction of a physician. Frequent monitoring of serum electrolytes is indicated. Because average plasma magnesium levels in some chronic CAPD patients have been observed to be elevated (Nolph et al. 1981), the magnesium concentration of this formulation has been reduced to 0.5 mEq/L. Average plasma magnesium levels have not been reported for chronic IPD and CCPD patients. Serum magnesium levels should be monitored and if low, oral magnesium supplements, oral magnesium containing phosphate binders, or peritoneal dialysis solutions containing higher magnesium concentrations may be used. Because average serum bicarbonate levels in some chronic CAPD patients (Nolph et al. 1981), some chronic IPD patients (La Greca et al. 1980), and some chronic CCPD patients (Diaz-Buxo et al. 1983) have been observed to be somewhat lower than normal values, the bicarbonate precursor (lactate) concentration of this formulation has been raised to 40 mEq/L. Serum bicarbonate levels should be monitored. The osmolarities shown in Table 1 are calculated values. As an example, measured osmolarity by freezing point depression determination of DIANEAL PD-2 peritoneal dialysis solution with 1.5% dextrose is approximately 334 mOsmol/L, compared with measured values in normal human serum of 280 mOsmol/L. This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda The plastic container is fabricated from a specially formulated polyvinyl chloride (PL 146 Plastic). The amount of water that can permeate from inside the container into the overwrap is insufficient to affect the solution significantly. Solutions in contact with the plastic container can leach out certain of its chemical components in very small amounts within the expiration period, e.g., di- 2-ethylhexyl phthalate (DEHP), up to 5 parts per million; however, the safety of the plastic has been confirmed in tests in animals according to USP biological tests for plastic containers as well as by tissue culture toxicity studies. Clinical Pharmacology Peritoneal dialysis is a procedure for removing toxic substances and metabolites normally excreted by the kidneys, and for aiding in the regulation of fluid and electrolyte balance. The procedure is accomplished by instilling peritoneal dialysis fluid through a conduit into the peritoneal cavity. With the exception of lactate, present as a bicarbonate precursor, electrolyte concentrations in the fluid have been formulated to attempt to normalize plasma electrolyte concentrations resulting from osmosis and diffusion across the peritoneal membrane (between the plasma of the patient and the dialysis fluid). Toxic substances and metabolites, present in high concentrations in the blood, cross the peritoneal membrane into the dialyzing fluid. Dextrose in the dialyzing fluid is used to produce a solution hyperosmolar to the plasma, creating an osmotic gradient which facilitates fluid removal from the patient’s plasma into the peritoneal cavity. After a period of time (dwell time), the fluid is drained from the cavity. Indications and Usage Peritoneal dialysis is indicated for patients in acute or chronic renal failure when nondialytic medical therapy is judged to be inadequate (Vaamonde and Perez 1977). It may also be indicated in the treatment of certain fluid and electrolyte disturbances, and for patients intoxicated with certain poisons and drugs (Knepshield et al. 1977). However, for many substances other methods of detoxification have been reported to be more effective than peritoneal dialysis (Vaamonde and Perez 1977; Chang 1977). Contraindications None known Warnings Peritoneal dialysis should be done with great care, if at all, in patients with a number of abdominal conditions including disruption of the peritoneal membrane or diaphragm by surgery or trauma, extensive adhesions, bowel distention, This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda undiagnosed abdominal disease, abdominal wall infection, hernias or burns, fecal fistula or colostomy, tense ascites, obesity, and large polycystic kidneys (Vaamonde and Perez 1977). Other conditions include recent aortic graft replacement and severe pulmonary disease. When assessing peritoneal dialysis as the mode of therapy in such extreme situations, the benefits to the patient must be weighed against the possible complications. An accurate fluid balance record must be kept and the weight of the patient carefully monitored to avoid over or under hydration with severe consequences including congestive heart failure, volume depletion, and shock. Excessive use of DIANEAL PD-2 peritoneal dialysis solution with 3.5% or 4.25% dextrose during a peritoneal dialysis treatment can result in significant removal of water from the patient. In acute renal failure patients, plasma electrolyte concentrations should be monitored periodically during the procedure. Stable patients undergoing maintenance peritoneal dialysis should have routine periodic evaluation of blood chemistries and hematologic factors, as well as other indicators of patient status. Because average plasma magnesium levels in chronic CAPD patients have been observed to be elevated (Nolph et al. 1981), the magnesium concentration of this formulation has been reduced to 0.5 mEq/L. Average plasma magnesium levels have not been reported for chronic IPD and CCPD patients. Serum magnesium levels should be monitored and if low, oral magnesium supplements, oral magnesium containing phosphate binders, or peritoneal dialysis solutions containing higher magnesium concentrations may be used. Because average serum bicarbonate levels in some chronic CAPD patients (Nolph et al. 1981), some chronic IPD patients (La Greca et al. 1980), and some chronic CCPD patients (Diaz-Buxo et al. 1983), have been observed to be somewhat lower than normal values, the bicarbonate precursor (lactate) concentration of this formulation has been raised to 40 mEq/L. Serum bicarbonate levels should be monitored. Not for use in the treatment of lactic acidosis. Potassium is omitted from DIANEAL PD-2 solutions because dialysis may be performed to correct hyperkalemia. Addition of potassium chloride should be made after careful evaluation of serum and total body potassium and only under the direction of a physician. The use of 5 or 6 liters of dialysis solution is not indicated in a single exchange. Refer to manufacturer’s directions accompanying drugs to obtain full information on additives. This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda If the resealable rubber plug on the medication port is missing or partially removed, do not use product if medication is to be added. After the pull ring has been removed, inspect connector of solution container for fluid flow. A few drops of solution within the connector or pull ring may be present due to condensation of water resulting from the sterilization process. If a continuous stream of fluid is noted, discard solution because sterility may be impaired. After removing overwrap, check for minute leaks by squeezing container firmly. If leaks are found, discard the solution because the sterility may be impaired. Freezing of solution may occur at temperatures below 0°C (32°F). Do not flex or manipulate container when frozen. Allow container to thaw naturally in ambient conditions and thoroughly mix contents by shaking. Precautions Aseptic technique must be used throughout the procedure and at its termination in order to reduce the possibility of infection. If peritonitis occurs, the choice and dosage of antibiotics should be based upon the results of identification and sensitivity studies of the isolated organism(s) when possible. Prior to identification of the involved organism(s), broad-spectrum antibiotics may be indicated. Peritoneal dialysis solutions may be warmed in the overpouch to 37°C (98.6°F) to enhance patient comfort. However, only dry heat (for example, heating pad) should be used. Solutions should not be heated in water due to an increased risk of infection. Microwave ovens should not be used to heat solutions because there is a potential for damage to the solution container. Moreover, microwave oven heating may potentially cause overheating and/or non-uniform heating of the solution that may result in patient injury or discomfort. Significant losses of protein, amino acids and water soluble vitamins may occur during peritoneal dialysis. Replacement therapy should be provided as necessary. Pregnancy: Teratogenic Effects Pregnancy Category C. Animal reproduction studies have not been conducted with DIANEAL peritoneal dialysis solutions. It is also not known whether DIANEAL peritoneal dialysis solutions can cause fetal harm when administered to a pregnant woman or can affect reproduction capacity. DIANEAL peritoneal dialysis solutions should be given to a pregnant woman only if clearly needed. Do not administer unless solution is clear and seal is intact. This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda Adverse Reactions Adverse reactions to peritoneal dialysis include mechanical and solution related problems as well as the results of contamination of equipment or improper technique in catheter placement. Abdominal pain, bleeding, peritonitis, subcutaneous infection around a chronic peritoneal catheter, catheter blockage, difficulty in fluid removal, and ileus are among the complications of the procedure. Solution related adverse reactions may include electrolyte and fluid imbalances, hypovolemia, hypervolemia, hypertension, hypotension, disequilibrium syndrome, and muscle cramping. Dosage and Administration DIANEAL PD-2 solutions are intended for intraperitoneal administration only. Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration whenever solution and container permit. The mode of therapy (Intermittent Peritoneal Dialysis [IPD], Continuous Ambulatory Peritoneal Dialysis [CAPD], or Continuous Cyclic Peritoneal Dialysis [CCPD]), frequency of treatment, formulation, exchange volume, duration of dwell, and length of dialysis should be selected by the physician responsible for and supervising the treatment of the individual patient. To avoid the risk of severe dehydration and hypovolemia and to minimize the loss of protein, it is advisable to select the peritoneal dialysis solution with the lowest level of osmolarity consistent with the fluid removal requirements for that exchange. Peritoneal dialysis solutions may be warmed in the overpouch to 37°C (98.6°F) to enhance patient comfort. However, only dry heat (for example, heating pad) should be used. (See Directions for Use) The addition of heparin to the dialysis solution may be indicated to aid in prevention of catheter blockage in patients with peritonitis, or when the solution drainage contains fibrinous or proteinaceous material (Ribot et al. 1966). 1000 to 2000 USP units of heparin per liter of solution has been recommended for adults (Furman et al. 1978). For children, 50 units of heparin per 100 mL of dialysis fluid has been recommended (Irwin et al. 1981). Additives may be incompatible. Complete information is not available. Those additives known to be incompatible should not be used. Consult with pharmacist, if available. If, in the informed judgement of the physician, it is deemed advisable to introduce additives, use aseptic technique. Mix thoroughly when additives have been introduced. Do not store solutions containing additives. This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda Intermittent Peritoneal Dialysis (IPD) For maintenance dialysis of chronic renal failure patients. The cycle of instillation, dwell and removal of dialysis fluid is repeated sequentially over a period of hours (8 to 36 hours) as many times per week as indicated by the condition of the patient. For chronic renal failure patients, maintenance dialysis is often accomplished by periodic dialysis (3 to 5 times weekly) for shorter time periods (8 to 14 hours per session) (Mattocks and El- Bassiouni 1971). Continuous Ambulatory Peritoneal Dialysis (CAPD) and Continuous Cyclic Peritoneal Dialysis (CCPD) For maintenance dialysis of chronic renal failure patients. In CAPD, 1.5 to 3.0 liters of dialysis solution (depending upon patient size) are instilled into the peritoneal cavity of adults and the peritoneal access device is then clamped (Kim et al. 1984; Twardowski and Janicka 1981; Twardowski and Burrows 1984). For children, 30 to 50 mL/kg body weight with a maximum of 2 liters has been recommended (Potter et al. 1981; Irwin et al. 1981). The solution remains in the cavity for dwell times of 4 to 8 hours during the day and 8 to 12 hours overnight. At the conclusion of each dwell period, the access device is opened, the solution drained and fresh solution instilled. The procedure is repeated 3 to 5 times per day, 6 to 7 days per week. Solution exchange volumes and frequency of exchanges should be individualized for adequate biochemical and fluid volume control (Moncrief et al. 1982; Twardowski et al. 1983). The majority of exchanges will utilize 1.5% or 2.5% dextrose containing peritoneal dialysis solutions, with 3.5% or 4.25% dextrose containing solutions being used when extra fluid removal is required. Patient weight is used as the indicator of the need for fluid removal (Popovich et al. 1978). In CCPD, the patient receives 3 or 4 dialysis exchanges during the night which range from 2-1/2 to 3 hours dwell duration. Typically 1.5 to 2.0 liters of dialysis solution (depending upon patient size) are delivered each cycle by an automatic peritoneal dialysis cycler machine. After the last outflow during the night, an additional exchange is infused by the cycler machine into the peritoneum. The equipment is then disconnected from the patient, and the dialysate remains in the peritoneum for 14 to 15 hours during the day until the next nocturnal cycle (Diaz- Buxo et al. 1981). Combinations of 1.5% or 2.5% dextrose containing peritoneal dialysis solutions are usually used for the nighttime exchanges, while 3.5% or 4.25% dextrose is used when extra fluid removal is required such as during the daytime exchange. Patient weight is used as the indicator of the need for fluid removal (Popovich et al. 1978) so therapy should be individualized according to the patient’s need for ultrafiltration. This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda It is recommended that adult patients being placed on chronic peritoneal dialysis or, in the case of pediatric patients, the selected caretaker, (as well as the patient, when suitable), should be appropriately trained in a program which is under the supervision of a physician. Training materials are available from Baxter Healthcare Corporation, Deerfield, IL 60015, USA to facilitate this training. How Supplied DIANEAL PD-2 peritoneal dialysis solutions in AMBU-FLEX II and AMBU-FLEX lll containers are available in nominal size flexible containers with fill volumes and dextrose concentrations as indicated in Table 1. All DIANEAL PD-2 peritoneal dialysis solutions have overfills which are declared on container labeling. Exposure of pharmaceutical products to heat should be minimized. Avoid excessive heat. It is recommended the product be stored at room temperature (25°C/77°F): brief exposure up to 40°C (104°F) does not adversely affect the product. Directions for Use Use aseptic technique. For complete system preparation, see directions accompanying ancillary equipment. Peritoneal dialysis solutions may be warmed in the overpouch to 37°C (98.6°F) to enhance patient comfort. However, only dry heat (for example, heating pad) should be used. Solutions should not be heated in water due to an increased risk of infection. Microwave ovens should not be used to heat solutions because there is a potential for damage to the solution container. Moreover, microwave oven heating may potentially cause overheating and/or non-uniform heating of the solution that may result in patient injury or discomfort.

For current labeling information, please visit https://www.fda.gov/drugsatfda DIANEAL Low Calcium Peritoneal Dialysis Solution AMBU-FLEX Container For Peritoneal Dialysis For intraperitoneal administration only Description DIANEAL Low Calcium peritoneal dialysis solutions in AMBU-FLEX containers are sterile, nonpyrogenic solutions for intraperitoneal administration only. They contain no bacteriostatic or antimicrobial agents or added buffers. Composition, calculated osmolarity, pH and ionic concentrations are shown in Table 1. Potassium is omitted from peritoneal dialysis solutions because dialysis may be performed to correct hyperkalemia. In situations in which there is a normal serum potassium level or hypokalemia, the addition of potassium chloride (up to a concentration of 4 mEq/L) may be indicated to prevent severe hypokalemia. Addition of potassium chloride should be made after careful evaluation of serum and total body potassium and only under the direction of a physician. Frequent monitoring of serum electrolytes is indicated. In some patients calcium carbonate is used as a phosphate binder. Because serum calcium levels have been observed to be elevated in these patients (Slatopolsky et al. 1986), the calcium concentration of DIANEAL Low Calcium peritoneal dialysis solutions has been reduced to 2.5 mEq/L. Serum calcium levels should be monitored and if low, the amount of oral calcium carbonate phosphate binder may be increased or peritoneal dialysis solutions containing higher calcium concentrations may be used. If serum calcium levels rise, adjustments to the dosage of the calcium carbonate phosphate binder and/or vitamin D analogs should be considered by the physician. Because average plasma magnesium levels in some chronic CAPD patients have been observed to be elevated (Nolph et al. 1981), the magnesium concentration of this formulation has been reduced to 0.5 mEq/L. Average plasma magnesium levels have not been reported for chronic IPD and CCPD patients. Serum magnesium levels should be monitored and if low, oral magnesium supplements, oral magnesium containing phosphate binders, or peritoneal dialysis solutions containing higher magnesium concentrations may be used. Because average serum bicarbonate levels in some chronic CAPD patients (Nolph et al. 1981), some chronic IPD patients (La Greca et al. 1980), and some chronic CCPD patients (Diaz-Buxo et al. 1983), have been observed to be somewhat lower than normal values, the bicarbonate precursor (lactate) concentration of DIANEAL Low Calcium peritoneal dialysis solutions has been raised to 40 mEq/L. Serum bicarbonate levels should be monitored. This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda The osmolarities shown in Table 1 are calculated values. Calculated osmolarity of DIANEAL Low Calcium peritoneal dialysis solution with 1.5% dextrose is 344 mOsmol/L, compared with measured values in normal human serum of 280 mOsmol/L. The plastic container is fabricated from a specially formulated polyvinyl chloride (PL 146 Plastic). The amount of water that can permeate from inside the container into the overpouch is insufficient to affect the solution significantly. Solutions in contact with the plastic container can leach out certain of its chemical components in very small amounts within the expiration period, e.g., di- 2-ethylhexyl phthalate (DEHP), up to 5 parts per million; however, the safety of the plastic has been confirmed in tests in animals according to USP biological tests for plastic containers as well as by tissue culture toxicity studies. Clinical Pharmacology Peritoneal dialysis is a procedure for removing toxic substances and metabolites normally excreted by the kidneys, and for aiding in the regulation of fluid and electrolyte balance. The procedure is accomplished by instilling peritoneal dialysis fluid through a conduit into the peritoneal cavity. With the exception of lactate, present as a bicarbonate precursor, electrolyte concentrations in the fluid have been formulated in an attempt to normalize plasma electrolyte concentrations resulting from osmosis and diffusion across the peritoneal membrane (between the patient’s plasma and the dialysis fluid). Toxic substances and metabolites, present in high concentrations in the blood, cross the peritoneal membrane into the dialyzing fluid. Dextrose in the dialyzing fluid is used to produce a solution hyperosmolar to the plasma, creating an osmotic gradient which facilitates fluid removal from the patient’s plasma into the peritoneal cavity. After a period of time (dwell time), the fluid is drained from the cavity. Indications and Usage DIANEAL Low Calcium peritoneal dialysis solutions are indicated for use in chronic renal failure patients being maintained on peritoneal dialysis. Contraindications None known. Warnings Peritoneal dialysis should be done with great care, if at all, in patients with a number of abdominal conditions including disruption of the peritoneal membrane This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda or diaphragm by surgery or trauma, extensive adhesions, bowel distention, undiagnosed abdominal disease, abdominal wall infection, hernias or burns, fecal fistula or colostomy, tense ascites, obesity, and large polycystic kidneys (Vaamonde and Perez 1977). Other conditions include recent aortic graft replacement and severe pulmonary disease. When assessing peritoneal dialysis as the mode of therapy in such extreme situations, the benefits to the patient must be weighed against the possible complications. An accurate fluid balance record must be kept and the weight of the patient carefully monitored to avoid over or under hydration with severe consequences including congestive heart failure, volume depletion, and shock. Excessive use of DIANEAL Low Calcium peritoneal dialysis solution with 3.5% or 4.25% dextrose during a peritoneal dialysis treatment can result in significant removal of water from the patient. Stable patients undergoing maintenance peritoneal dialysis should have routine periodic evaluation of blood chemistries and hematologic factors, as well as other indicators of patient status. In some patients calcium carbonate is used as a phosphate binder. Because serum calcium levels have been observed to be elevated in these patients (Slatopolsky et al. 1986), the calcium concentration of DIANEAL Low Calcium peritoneal dialysis solutions has been reduced to 2.5 mEq/L. Serum calcium levels should be monitored and if low, the amount of oral calcium carbonate phosphate binder may be increased or peritoneal dialysis solutions containing higher calcium concentrations may be used. If serum calcium levels rise, adjustments to the dosage of the calcium carbonate phosphate binder and/or vitamin D analogs should be considered by the physician. Because average plasma magnesium levels in some chronic CAPD patients have been observed to be elevated (Nolph et al. 1981), the magnesium concentration of this formulation has been reduced to 0.5 mEq/L. Average plasma magnesium levels have not been reported for chronic IPD and CCPD patients. Serum magnesium levels should be monitored and if low, oral magnesium supplements, oral magnesium containing phosphate binders, or peritoneal dialysis solutions containing higher magnesium concentrations may be used. Because average serum bicarbonate levels in some chronic CAPD patients (Nolph et al. 1981), some chronic IPD patients (La Greca et al. 1980), and some chronic CCPD patients (Diaz-Buxo et al. 1983), have been observed to be somewhat lower than normal values, the bicarbonate precursor (lactate) concentration of DIANEAL Low Calcium peritoneal dialysis solutions has been raised to 40 mEq/L. Serum bicarbonate levels should be monitored. This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda Not for use in the treatment of lactic acidosis. Potassium is omitted from DIANEAL Low Calcium peritoneal dialysis solutions because dialysis may be performed to correct hyperkalemia. Addition of potassium chloride should be made after careful evaluation of serum and total body potassium and only under the direction of a physician. The use of 5 or 6 liters of dialysis solution is not indicated in a single exchange. Refer to manufacturer’s directions accompanying drugs to obtain full information on additives. If the resealable rubber plug on the medication port is missing or partially removed, do not use product if medication is to be added. After the pull ring has been removed, inspect connector of solution container for fluid flow. A few drops of solution within the connector or pull ring may be present due to condensation of water resulting from the sterilization process. If a continuous stream of fluid is noted, discard solution because sterility may be impaired. After removing overpouch, check for minute leaks by squeezing container firmly. If leaks are found, discard the solution because the sterility may be impaired. Freezing of solution may occur at temperatures below 0°C (32°F). Allow to thaw naturally in ambient conditions and thoroughly mix contents by shaking. Precautions Aseptic technique must be used throughout the procedure and at its termination in order to reduce the possibility of infection. If peritonitis occurs, the choice and dosage of antibiotics should be based upon the results of identification and sensitivity studies of the isolated organism(s) when possible. Prior to identification of the involved organism(s), broad-spectrum antibiotics may be indicated. Peritoneal dialysis solutions may be warmed in the overpouch to 37°C (98.6°F) to enhance patient comfort. However, only dry heat (for example, heating pad) should be used. Solutions should not be heated in water due to an increased risk of infection. Microwave ovens should not be used to heat solutions because there is a potential for damage to the solution container. Moreover, microwave oven heating may potentially cause overheating and/or non-uniform heating of the solution that may result in patient injury or discomfort. This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda Significant losses of protein, amino acids and water soluble vitamins may occur during peritoneal dialysis. Replacement therapy should be provided as necessary. Pregnancy: Teratogenic Effects Pregnancy Category C. Animal reproduction studies have not been conducted with DIANEAL Low Calcium peritoneal dialysis solutions. It is also not known whether DIANEAL Low Calcium peritoneal dialysis solutions can cause fetal harm when administered to a pregnant woman or can affect reproduction capacity. DIANEAL Low Calcium peritoneal dialysis solutions should be given to a pregnant woman only if clearly needed. Do not administer unless solution is clear and seal is intact. Adverse Reactions Adverse reactions to peritoneal dialysis include mechanical and solution related problems as well as the results of contamination of equipment or improper technique in catheter placement. Abdominal pain, bleeding, peritonitis, subcutaneous infection around a chronic peritoneal catheter, catheter blockage, difficulty in fluid removal, and ileus are among the complications of the procedure. Solution related adverse reactions may include electrolyte and fluid imbalances, hypovolemia, hypervolemia, hypertension, hypotension, disequilibrium syndrome, and muscle cramping. When prescribing the solution to be used for an individual patient, consideration should be given to the potential interaction between the dialysis treatment and therapy directed at other existing illnesses. For example, rapid potassium removal may create arrhythmias in cardiac patients using digitalis or similar drugs; digitalis toxicity may be masked by elevated potassium or magnesium, or by hypocalcemia. Correction of electrolytes by dialysis may precipitate signs and symptoms of digitalis excess. Conversely, toxicity may occur at suboptimal dosages of digitalis if potassium is low or calcium high. Azotemic diabetics require careful monitoring of insulin requirements during and following dialysis with dextrose containing solutions. Dosage and Administration DIANEAL Low Calcium peritoneal dialysis solutions are intended for intraperitoneal administration only. Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration whenever solution and container permit. This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda The mode of therapy (Intermittent Peritoneal Dialysis [IPD], Continuous Ambulatory Peritoneal Dialysis [CAPD], or Continuous Cyclic Peritoneal Dialysis [CCPD]), frequency of treatment, formulation, exchange volume, duration of dwell, and length of dialysis should be selected by the physician responsible for and supervising the treatment of the individual patient. To avoid the risk of severe dehydration and hypovolemia and to minimize the loss of protein, it is advisable to select the peritoneal dialysis solution with the lowest level of osmolarity consistent with the fluid removal requirements for that exchange. Peritoneal dialysis solutions may be warmed in the overpouch to 37°C (98.6°F) to enhance patient comfort. However, only dry heat (for example, heating pad) should be used. (See Directions for Use) The addition of heparin to the dialysis solution may be indicated to aid in prevention of catheter blockage in patients with peritonitis, or when the solution drainage contains fibrinous or proteinaceous material (Ribot et al. 1966). 1000 to 2000 USP units of heparin per liter of solution has been recommended for adults (Furman et al. 1978). For children, 50 units of heparin per 100 mL of dialysis fluid has been recommended (Irwin et al. 1981). Additives may be incompatible. Complete information is not available. Those additives known to be incompatible should not be used. Consult with pharmacist, if available. If, in the informed judgment of the physician, it is deemed advisable to introduce additives, use aseptic technique. Mix thoroughly when additives have been introduced. Do not store solutions containing additives. Intermittent Peritoneal Dialysis (IPD) For maintenance dialysis of chronic renal failure patients. The cycle of instillation, dwell and removal of dialysis fluid is repeated sequentially over a period of hours (8 to 36 hours) as many times per week as indicated by the condition of the patient. For chronic renal failure patients, maintenance dialysis is often accomplished by periodic dialysis (3 to 5 times weekly) for shorter time periods (8 to 14 hours per session) (Mattocks and El- Bassiouni 1971). Continuous Ambulatory Peritoneal Dialysis (CAPD) and Continuous Cyclic Peritoneal Dialysis (CCPD) For maintenance dialysis of chronic renal failure patients. In CAPD, typically 1.5 to 3.0 liters of dialysis solution (depending upon patient size) are instilled into the peritoneal cavity of adults and the peritoneal access This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda device is then clamped (Kim et al. 1984; Twardowski and Janicka 1981; Twardowski and Burrows 1984). For children, 30 to 50 mL/kg body weight with a maximum of 2 liters has been recommended (Potter et al. 1981; Irwin et al. 1981). The solution remains in the cavity for dwell times of 4 to 8 hours during the day and 8 to 12 hours overnight. At the conclusion of each dwell period, the access device is opened, the solution drained and fresh solution instilled. The procedure is repeated 3 to 5 times per day, 6 to 7 days per week. Solution exchange volumes and frequency of exchanges should be individualized for adequate biochemical and fluid volume control (Moncrief et al. 1982; Twardowski et al. 1983). The majority of exchanges will utilize 1.5% or 2.5% dextrose containing peritoneal dialysis solutions, with 3.5% or 4.25% dextrose containing solutions being used when extra fluid removal is required. Patient weight is used as the indicator of the need for fluid removal (Popovich et al. 1978). In CCPD, the patient receives 3 or 4 dialysis exchanges during the night which range from 2-1/2 to 3 hours dwell duration. Typically 1.5 to 2.0 liters of dialysis solution (depending upon patient size) are delivered each cycle by an automatic peritoneal dialysis cycler machine. After the last outflow during the night, an additional exchange is infused by the cycler machine into the peritoneum. The equipment is then disconnected from the patient, and the dialysate remains in the peritoneum for 14 to 15 hours during the day until the next nocturnal cycle (Diaz-Buxo et al. 1981). Combinations of 1.5% or 2.5% dextrose containing peritoneal dialysis solutions are usually used for the nighttime exchanges, while 3.5% or 4.25% dextrose containing solution is used when extra fluid removal is required such as during the daytime exchange. Patient weight is used as the indicator of the need for fluid removal (Popovich et al. 1978) so therapy should be individualized according to the patient’s need for ultrafiltration. It is recommended that adult patients being placed on peritoneal dialysis or, in the case of pediatric patients, the selected caretaker, (as well as the patient, when suitable), should be appropriately trained in a program which is under the supervision of a physician. Training materials are available from Baxter Healthcare Corporation, Deerfield, IL 60015 USA to facilitate this training.

DIANEAL Peritoneal Dialysis Solution For intraperitoneal administration only DIANEAL PD-2 Peritoneal Dialysis Solution With 1.5% Dextrose DIANEAL PD-2 Peritoneal Dialysis Solution With 2.5% Dextrose DIANEAL PD-2 Peritoneal Dialysis Solution With 4.25% Dextrose DIANEAL Low Calcium (2.5 mEq/L) Peritoneal Dialysis Solution With 1.5% Dextrose DIANEAL Low Calcium (2.5 mEq/L) Peritoneal Dialysis Solution With 2.5% Dextrose DIANEAL Low Calcium (2.5 mEq/L) Peritoneal Dialysis Solution With 4.25% Dextrose DESCRIPTION DIANEAL Peritoneal Dialysis Solutions are sterile, nonpyrogenic solutions in flexible containers for intraperitoneal administration only. The peritoneal dialysis solutions contain no bacteriostatic or antimicrobial agents. Composition, calculated osmolarity, pH, and ionic concentrations are shown in Tables 1-6. DIANEAL is a hyperosmolar solution. The plastic container is fabricated from polyvinyl chloride (PL 146 Plastic). Exposure to temperatures above 25°C/77°F during transport and storage will lead to minor losses in moisture content. Higher temperatures lead to greater losses. It is unlikely that these minor losses will lead to clinically significant changes within the expiration period. The amount of water that can permeate from inside the solution container into the overwrap is insufficient to affect the solution significantly. Solutions in contact with the plastic container can leach out certain of its chemical components in very small amounts within the expiration period, e.g. di-2-ethylhexyl phthalate (DEHP), up to 5 parts per million; however, the safety of the plastic has been confirmed in tests in animals according to USP biological tests for plastic containers as well as by cell culture toxicity studies. CLINICAL PHARMACOLOGY Mechanism of Action DIANEAL is a hypertonic peritoneal dialysis solution containing dextrose, a monosaccharide, as the primary osmotic agent. An osmotic gradient must be created between the peritoneal membrane and the dialysis solution in order for ultrafiltration to occur. The hypertonic concentration of glucose in DIANEAL exerts an osmotic pressure across the peritoneal membrane resulting in transcapillary ultrafiltration. Like other peritoneal dialysis solutions, DIANEAL contains electrolytes to facilitate the correction of electrolyte abnormalities. DIANEAL contains a buffer, lactate, to help normalize acid- base abnormalities. Pharmacokinetics of DIANEAL Glucose content in DIANEAL is expressed as dextrose monohydrate and is available in three concentrations: 1.5%, 2.5% and 4.25%. Reference ID: 3799174 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda Glucose is rapidly absorbed from the peritoneal cavity by diffusion and appears quickly in the circulation due to the high glucose concentration gradient between DIANEAL compared to blood capillary glucose level. Absorption per unit time will be the highest at the start of an exchange and decreases over time. The rate of glucose absorption will be dependent upon the transport characteristics of the patient’s peritoneal membrane as determined by a peritoneal equilibration test (PET). Glucose absorption will also depend upon the concentration of glucose used for the exchange and the length of the dwell. Glucose is metabolized by normal cellular pathways (e.g. glycolysis) and provides a source of calories and may elevate blood glucose levels. Transport of other molecules across the peritoneal membrane, such as lactate, will occur by diffusion. Metabolism of lactate occurs in the liver and results in the generation of the bicarbonate. Transport of other molecules will be dependent upon the molecular size of the solute, the concentration gradient, and the effective peritoneal surface area as determined by the PET. INDICATIONS AND USAGE DIANEAL peritoneal dialysis solutions are indicated for patients in acute or chronic renal failure when nondialytic medical therapy is judged to be inadequate. CONTRAINDICATIONS DIANEAL is contraindicated in patients with pre-existing severe lactic acidosis. WARNINGS Encapsulating Peritoneal Sclerosis (EPS) is considered to be a known, rare complication of peritoneal dialysis therapy. EPS has been reported in patients using peritoneal dialysis solutions including DIANEAL. Infrequently, fatal outcomes of EPS have been reported with DIANEAL. Because Dianeal is a dextrose-based solution, patients with allergy to corn or corn products are at increased risk for allergic reaction, which may include anaphylactic/anaphylactoid reactions. Stop the infusion immediately, drain the solution from the peritoneal cavity and treat appropriately if any signs or symptoms of a suspected hypersensitivity reaction develop. Patients with severe lactic acidosis should not be treated with lactate-based peritoneal dialysis solutions (See Contraindications). Patients with conditions known to increase the risk of lactic acidosis [e.g., severe hypotension or sepsis that can be associated with acute renal failure, hepatic failure, inborn errors of metabolism, and treatment with drugs such as nucleoside/nucleotide reverse transcriptase inhibitors (NRTIs)] must be monitored for the occurrence of lactic acidosis before the start of treatment and during treatment with lactate-based peritoneal dialysis solutions. When prescribing the solution to be used for an individual patient, consideration should be given to the potential interaction between the dialysis treatment and therapy directed at other existing illnesses. Serum potassium levels should be monitored carefully in patients treated with cardiac glycosides. For example, rapid potassium removal may create arrhythmias in cardiac patients using digitalis or similar drugs; digitalis toxicity may be masked by hyperkalemia, hypermagnesemia, or hypocalcemia. Correction of electrolytes by dialysis may precipitate signs and symptoms of digitalis excess. Conversely, toxicity may occur at suboptimal dosages of digitalis if potassium is low or calcium is high. Diabetics require careful monitoring of insulin requirements and other treatments for hyperglycemia during and following dialysis with dextrose containing solutions. Reference ID: 3799174 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda PRECAUTIONS General Peritoneal-Dialysis Related DIANEAL is intended for intraperitoneal administration only. Not for intravenous administration. The following conditions may predispose to adverse reactions to peritoneal dialysis procedures: abdominal conditions, including uncorrectable mechanical defects that prevent effective peritoneal dialysis or increase the risk of infection, disruption of the peritoneal membrane and diaphragm by surgery, congenital anomalies or trauma prior to complete healing, abdominal tumors, abdominal wall infections, hernias, fecal fistula, colostomies or ileostomies, frequent episodes of diverticulitis, inflammatory or ischemic bowel disease, large polycystic kidneys, or other conditions that compromise the integrity of the abdominal wall, abdominal surface, or intra-abdominal cavity, such as documented loss of peritoneal function or extensive adhesions that compromise peritoneal function. Conditions that preclude normal nutrition, impaired respiratory function, recent aortic graft placement, and potassium deficiency may also predispose to complications of peritoneal dialysis. Aseptic technique must be employed throughout the peritoneal dialysis procedure to reduce the possibility of infection. Following use, the drained fluid should be inspected for the presence of fibrin or cloudiness, which may indicate the presence of peritonitis. If peritonitis occurs, the choice and dosage of antibiotics should be based upon the results of identification and sensitivity studies of the isolated organism(s) when possible. Prior to identification of the involved organism(s), broad-spectrum antibiotics may be indicated. Overinfusion of peritoneal dialysis solution volume into the peritoneal cavity may be characterized by abdominal distention, feeling of fullness and/or shortness of breath. Treatment of overinfusion is to drain the peritoneal dialysis solution from the peritoneal cavity. Need for Trained Physician Treatment should be initiated and monitored under the supervision of a physician knowledgeable in the management of patients with renal failure. A patient’s volume status should be carefully monitored to avoid hyper- or hypovolemia and potentially severe consequences including congestive heart failure, volume depletion and hypovolemic shock. An accurate fluid balance record must be kept and the patient’s body weight monitored. Excessive use of DIANEAL peritoneal dialysis solution with higher dextrose concentration during a peritoneal dialysis treatment may result in significant removal of water from the patient (see Dosage and Administration). Significant losses of protein, amino acids, water-soluble vitamins and other medicines may occur during peritoneal dialysis. The patient’s nutritional status should be monitored and replacement therapy should be provided as necessary. Information for Patients Patients should be instructed not to use solutions if they are cloudy, discolored, contain visible particulate matter, or if they show evidence of leaking containers (see Dosage and Administration). Aseptic technique must be employed throughout the procedure. An improper clamping sequence may result in infusion of air into the peritoneum (see Dosage and Administration, Directions for Use). Reference ID: 3799174 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda To reduce possible discomfort during administration, patients should be instructed that solutions may be warmed to 37°C (98°F) prior to use. Only dry heat should be used. It is best to warm solutions within the overwrap using a heating pad. To avoid contamination, solutions should not be immersed in water for warming. Do not use a microwave oven to warm the solution (see Dosage and Administration, Directions for Use). Laboratory Tests Serum Electrolytes DIANEAL does not contain potassium. Evaluate serum potassium prior to administering potassium chloride to the patient. In situations where there is a normal serum potassium level or hypokalemia, addition of potassium chloride (up to a concentration of 4 mEq/L) to the solution may be necessary to prevent severe hypokalemia. This should be made under careful evaluation of serum and total body potassium, and only under the direction of a physician. Fluid, hematology, blood chemistry, electrolyte concentrations, and bicarbonate should be monitored periodically. If serum magnesium levels are low, magnesium supplements may be used. Patients receiving DIANEAL solutions should have their calcium levels monitored for the development of hypocalcemia or hypercalcemia. In these circumstances, adjustments to the dosage of the phosphate binders, vitamin D analogs, and/or calcimimetics should be considered by the physician. DIANEAL Low Calcium (2.5 mEq/L) Peritoneal Dialysis solution should be considered for use in patients with hypercalcemia. Carcinogenesis, Mutagenesis, Impairment of Fertility Studies to evaluate the carcinogenic or mutagenic potential of this product, or its potential to affect fertility adversely, have not been performed. Drug Interactions No clinical drug interaction studies were performed. As with other dialysis solutions, blood concentrations of dialyzable drugs may be reduced by dialysis. Dosage adjustment of concomitant medications may be necessary. In patients using cardiac glycosides (digoxin and others), plasma levels of calcium, potassium and magnesium must be carefully monitored (see Warnings). Use in Specific Population Pregnancy Pregnancy Category C. DIANEAL is a peritoneal dialysis solution of electrolytes, lactate and dextrose and is pharmacologically inactive. Animal reproduction studies have not been conducted with DIANEAL dialysis solution. While there are no adequate and well controlled studies in pregnant women, appropriate administration of DIANEAL with monitoring of fluid, electrolyte, acid-base and glucose balance, is not expected to cause fetal harm, or affect reproductive capacity. Maintenance of normal acid-base balance is important for fetal well being. Physicians should carefully consider the potential risks and benefits for each specific patient before prescribing DIANEAL. Nursing Mothers DIANEAL is a dialysis solution of electrolytes, lactate and dextrose and is pharmacologically inactive. The components of DIANEAL are excreted in human milk. Appropriate administration of DIANEAL with monitoring of fluid, electrolyte, acid-base and glucose balance, is not expected to harm a nursing infant. Physicians should carefully consider the potential risks and benefits for each specific patient before prescribing DIANEAL. Pediatric Use Safety and effectiveness have been established based on published clinical data. No adequate and well-controlled studies have been conducted with DIANEAL solutions in pediatric patients. Reference ID: 3799174 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda Geriatric Use Safety and effectiveness have been established based on published clinical data. ADVERSE REACTIONS The following adverse reactions have been identified during post approval use of DIANEAL. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship during drug exposure. Adverse reactions are listed by MedDRA System Organ Class (SOC), then by Preferred Term in order of severity. INFECTIONS AND INFESTATIONS: Fungal peritonitis, Peritonitis bacterial, Catheter related infection METABOLISM AND NUTRITION DISORDERS: Hypovolemia, Hypervolemia, Fluid retention, Hypokalemia, Hyponatremia, Dehydration, Hypochloremia VASCULAR DISORDERS: Hypotension, Hypertension RESPIRATORY, THORACIC, AND MEDIASTINAL DISORDERS: Dyspnea GASTROINTESTINAL DISORDERS: Sclerosing encapsulating peritonitis, Peritonitis, Peritoneal cloudy effluent, Vomiting, Diarrhea, Nausea, Constipation, Abdominal pain, Abdominal distension, Abdominal discomfort SKIN AND SUBCUTANEOUS DISORDERS: Stevens-Johnson syndrome, Urticaria, Rash, (including pruritic, erythematous and generalized), Pruritus MUSCULOSKELETAL, CONNECTIVE TISSUE DISORDERS: Myalgia, Muscle spasms, Musculoskeletal pain GENERAL DISORDERS AND ADMINISTRATION SITE CONDITIONS: Generalized edema, Pyrexia, Malaise, Infusion site pain, Catheter related complication DRUG ABUSE AND DEPENDENCE There has been no observed potential of drug abuse or dependence with DIANEAL solution. OVERDOSAGE There is a potential for overdose resulting in hypervolemia, hypovolemia, electrolyte disturbances or hyperglycemia. Excessive use of DIANEAL peritoneal dialysis solution with 4.25% dextrose during a peritoneal dialysis treatment can result in significant removal of water from the patient. DOSAGE AND ADMINISTRATION DIANEAL peritoneal dialysis solutions are intended for intraperitoneal administration only. The mode of therapy, frequency of treatment, formulation, exchange volume, duration of dwell, and length of dialysis should be selected by the physician responsible for and supervising the treatment of the individual patient. DIANEAL should be administered at a rate that is comfortable for the patient, generally over a period of 10-20 minutes for a single exchange. Patients on continuous ambulatory peritoneal dialysis (CAPD) typically perform 4 cycles per day (24 hours). Patients on automated peritoneal dialysis (APD) typically perform 4-5 cycles at night and up Reference ID: 3799174 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda to 2 cycles during the day. The fill volume depends on body size, usually from 2.0 to 2.5 liters per 1.73m2 . To avoid the risk of severe dehydration and hypovolemia and to minimize the loss of protein, it is advisable to select the peritoneal dialysis solution with the lowest level of osmolarity consistent with the fluid removal requirements for that exchange. As the patient’s body weight becomes closer to the ideal dry weight, lowering the dextrose concentration of DIANEAL is recommended. DIANEAL 4.25% dextrose-containing solution has the highest osmolarity of the DIANEAL solutions and using it for all exchanges may cause dehydration. Solutions that are cloudy, discolored, contain visible particulate matter, or show evidence of leakage should not be used. Following use, the drained fluid should be inspected for the presence of fibrin or cloudiness which may indicate the presence of peritonitis. For single use only. Discard unused portion. It is recommended that patients being placed on peritoneal dialysis and/or their caretaker(s) should be appropriately trained. Addition of Potassium Potassium is omitted from DIANEAL solutions because dialysis may be performed to correct hyperkalemia. In situations where there is a normal serum potassium level or hypokalemia, the addition of potassium chloride (up to a concentration of 4 mEq/L) may be indicated to prevent severe hypokalemia. The decision to add potassium chloride should be made by the physician after careful evaluation of serum potassium. Addition of Insulin Patients with insulin-dependent diabetes may require modification of insulin dosage following initiation of treatment with DIANEAL. Appropriate monitoring of blood glucose should be performed when initiating DIANEAL in diabetic patients and insulin dosage adjusted if needed (see Warnings). Addition of Heparin No human drug interaction studies with heparin were conducted. In vitro studies demonstrated no evidence of incompatibility of heparin with DIANEAL. Addition of Antibiotics No formal clinical drug interaction studies have been performed. In vitro studies of the following medications have demonstrated stability with DIANEAL: amphotericin B, ampicillin, cefazolin, cefepime, cefotaxime, ceftazidime, ceftriaxone, ciprofloxacin, clindamycin, deferoxamine, erythromycin, gentamicin, linezolid, mezlocillin, miconazole, moxifloxacin, nafcillin, ofloxacin, penicillin G, piperacillin, sulfamethoxazole/trimethoprim, ticarcillin, tobramycin, and vancomycin. However, aminoglycosides should not be mixed with penicillins due to chemical incompatibility. Directions for Use For complete CAPD and APD system preparation, see directions accompanying ancillary equipment. Aseptic technique must be used throughout the peritoneal dialysis procedure. Warming For patient comfort, DIANEAL can be warmed to 37°C (98°F). Only dry heat should be used. It is best to warm solutions within the overwrap using a heating pad. Do not immerse DIANEAL in water for warming. Do not use a microwave oven to warm DIANEAL. Reference ID: 3799174 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda To Open To open, tear the overwrap down at the slit and remove the solution container. Some opacity of the plastic, due to moisture absorption during the sterilization process, may be observed. This does not affect the solution quality or safety and may often leave a slight amount of moisture within the overwrap. The opacity should diminish gradually. Inspect for Container Integrity Inspect the bag connector to ensure the tip protector (pull ring, blue pull tip, or blue twist-off tip) is attached. Do not use if the tip protector is not attached to the connector. Inspect the DIANEAL container for signs of leakage and check for minute leaks by squeezing the container firmly. If the container has frangible(s), inspect that they are positioned correctly and are not broken. Do not use DIANEAL if the frangible(s) are broken or leaks are suspected as sterility may be impaired. For DIANEAL in UltraBag, inspect the tubing and drain container for presence of solution. Small droplets are acceptable, but if solution flows past the frangible prior to use, do not use and discard the units. Adding Medications Some drug additives may be incompatible with DIANEAL. See DOSAGE AND ADMINISTRATION section for additional information. If the resealable rubber plug on the medication port is missing or partly removed, do not use the product if medication is to be added. 1. Put on mask. Clean and/or disinfect hands. 2. Prepare medication port site using aseptic technique. 3. Using a syringe with a 1-inch long, 25- to 19-gauge needle, puncture the medication port and inject additive. 4. Reposition container with container ports up and evacuate medication port by squeezing and tapping it. 5. Mix solution and additive thoroughly.

It contains no antimicrobial agents. Mannitol** is a six carbon sugar alcohol prepared commercially by the reduction of dextrose. Although virtually inert metabolically in humans, it occurs naturally in fruits and vegetables. Mannitol is an obligatory osmotic diuretic. The pH may have been adjusted with sodium hydroxide and/or hydrochloric acid. Composition, osmolarity, and pH are shown in Table 1.

For example, the AVIVA container system is compatible with and appropriate for use in the admixture and administration of paclitaxel. In addition, the AVIVA container system is compatible with and appropriate for use in the admixture and administration of all drugs deemed compatible with existing polyvinyl chloride container systems. The solution contact materials do not contain PVC, DEHP, or other plasticizers. The suitability of the container materials has been established through biological evaluations, which have shown the container passes Class VI U.S. Pharmacopeia (USP) testing for plastic containers. These tests confirm the biological safety of the container system. The flexible container is a closed system, and air is prefilled in the container to facilitate drainage. The container does not require entry of external air during administration. The container has two ports: one is the administration outlet port for the attachment of an intravenous administration set and the other port has a medication site for addition of supplemental medication (See Directions for Use). The primary function of the overwrap is to protect the container from the physical environment. Clinical Pharmacology Osmitrol Injection (Mannitol Injection, USP) is one of the nonelectrolyte, obligatory, osmotic diuretics. It is freely filterable at the renal glomerulus, only poorly reabsorbed by the renal tubule, not secreted by the tubule, and is pharmacologically inert. Mannitol, when administered intravenously, exerts its osmotic effect as a solute of relatively small molecular size being largely confined to the extracellular space. Only relatively small amounts of the dose administered is metabolized. Mannitol is readily diffused through the glomerulus of the kidney over a wide range of normal and impaired kidney function. In this fashion, approximately 80% of a 100 gram dose of mannitol will appear in the urine in three hours with lesser amounts thereafter. Even at peak concentrations, mannitol will exhibit less than 10% of tubular reabsorption and is not secreted by tubular cells. Mannitol will hinder tubular reabsorption of water and enhance excretion of sodium This label may not be the latest approved by FDA.

This increase in extracellular osmolarity effected by the intravenous administration of mannitol will induce the movement of intracellular water to the extracellular and vascular spaces. This action underlies the role of mannitol in reducing intracranial pressure, intracranial edema, and elevated intraocular pressure. Indications and Usage Osmitrol Injection (Mannitol Injection, USP) is indicated for: The promotion of diuresis, in the prevention and/or treatment of the oliguric phase of acute renal failure before irreversible renal failure becomes established; The reduction of intracranial pressure and treatment of cerebral edema by reducing brain mass; The reduction of elevated intraocular pressure when the pressure cannot be lowered by other means, and promoting the urinary excretion of toxic substances. Contraindications Osmitrol Injection (Mannitol Injection, USP) is contraindicated in patients with: Well established anuria due to severe renal disease, severe pulmonary congestion or frank pulmonary edema, active intracranial bleeding except during craniotomy, severe dehydration,Progressive renal damage or dysfunction after institution of mannitol therapy, including increasing oliguria and azotemia, and progressive heart failure or pulmonary congestion after institution of mannitol therapy. Warnings In patients with severe impairment of renal function, a test dose should be utilized (see Dosage and Administration). A second test dose may be tried if there is an inadequate response, but no more than two test doses should be attempted. The obligatory diuretic response following rapid infusion of 15% or 20% mannitol injection may further aggravate preexisting hemoconcentration. Excessive loss of water and electrolytes may lead to serious imbalances. Serum sodium and potassium should be carefully monitored during mannitol administration. If urine output continues to decline during mannitol infusion, the patient’s clinical status should be closely reviewed and mannitol infusion suspended if necessary. Accumulation of mannitol may result in overexpansion of the extracellular fluid which may intensify existing or latent congestive heart failure. Excessive loss of water and electrolytes may lead to serious imbalances. With continued administration of mannitol, loss of water in excess of electrolytes can cause hypernatremia. Electrolyte measurements, including sodium and potassium, are therefore, of vital importance in monitoring the This label may not be the latest approved by FDA.

Osmotic nephrosis, a reversible vacuolization of the tubules of unknown clinical significance, may proceed to severe irreversible nephrosis, so that the renal function must be closely monitored during mannitol infusion. Precautions General Do not connect flexible plastic containers of intravenous solutions in series, i.e., do not piggyback connections. Such use could result in air embolism due to residual air being drawn from one container before administration of the fluid from a secondary container is completed. Pressurizing intravenous solutions contained in flexible plastic containers to increase flow rates can result in air embolism if the residual air in the container is not fully evacuated prior to administration. Use of a vented intravenous administration set with the vent in the open position could result in air embolism. Vented intravenous administration sets with the vent in the open position should not be used with flexible plastic containers. The cardiovascular status of the patient should be carefully evaluated before rapidly administrating mannitol since sudden expansion of the extracellular fluid may lead to fulminating congestive heart failure. Shift of sodium free intracellular fluid into the extracellular compartment following mannitol infusion may lower serum sodium concentration and aggravate preexisting hyponatremia. By sustaining diuresis, mannitol administration may obscure and intensify inadequate hydration or hypovolemia. Electrolyte free mannitol should not be given conjointly with blood. If it is essential that blood be given simultaneously, at least 20 mEq of sodium chloride should be added to each liter of mannitol solution to avoid pseudoagglutination. When exposed to low temperatures, solutions of mannitol may crystallize. Concentrations greater than 15% have a greater tendency to crystallization. Inspect for crystals prior to administration. If crystals are visible, redissolve by warming the solution up to 70°C, with agitation. Allow the solution to cool to room temperature before reinspection for crystals. Administer intravenously using sterile, filter- type administration set. Laboratory Tests Although blood levels of mannitol can be measured, there is little if any clinical virtue in doing so.

Adverse Reactions Extensive use of mannitol over the last several decades has produced recorded adverse events, in a variety of clinical settings, that are isolated or idiosyncratic in nature. None of these adverse reactions have occurred with any great frequency nor with any security in attributing them to mannitol. The inability to clearly exclude the drug related nature of such events in these isolated reports prompts the necessity to list the reactions that have been observed in patients during or following mannitol infusion. In this fashion, patients have exhibited nausea, vomiting, rhinitis, local pain, skin necrosis and thrombophlebitis at the site of infection, chills, dizziness, urticaria, hypotension, hypertension, tachycardia, fever and angina-like chest pains. Of far greater clinical significance is a variety of events that are related to inappropriate recognition and monitoring of fluid shifts. These are not intrinsic adverse reactions to the drug but the consequence of manipulating osmolarity by any agency in a therapeutically inappropriate manner. Failure to recognize severe impairment of renal function with the high likelihood of nondiuretic response can lead to aggravated dehydration of tissues and increased vascular fluid load. Induced diuresis in the presence of preexisting hemoconcentration and preexisting deficiency of water and electrolytes can lead to serious imbalances. Expansion of the extracellular space can aggravate cardiac decompensation or induce it in the presence of latent heart failure. Pulmonary congestion or edema can be seriously aggravated with the expansion of the extracellular and therefore intravascular fluid load. Hemodilution and dilution of the extracellular fluid space by osmotic shift of water can induce or aggravate preexisting hyponatremia. If unrecognized, such fluid and/or electrolyte shift can produce the reported adverse reactions of pulmonary congestion, acidosis, electrolyte loss, dryness of mouth, thirst, edema, headache, blurred vision, convulsions and congestive cardiac failure. These are not truly adverse reactions to the drug and can be appropriately prevented by evaluation of degree of renal failure with a test dose response to mannitol when indicated; evaluation of hypervolemia and hypovolemia; sodium and potassium levels; hemodilution or hemoconcentration; and evaluation of renal, cardiac and pulmonary function at the onset of therapy. Dosage and Administration Osmitrol Injection (Mannitol Injection, USP) should be administered only by intravenous infusion. The total dosage, concentration, and rate of administration should be governed by the nature and severity of the condition being treated, fluid requirement, and urinary output. The usual adult dosage ranges from 20 to 100 g in a 24 hour period, but in most instances an adequate response will be achieved at a dosage of approximately 50 to 100 g in a 24 hour period. The rate of administration is usually adjusted to maintain a urine flow of at least 30 to 50 mL/hour. This outline of administration This label may not be the latest approved by FDA.

Parenteral dug products should be inspected visually for particulate matter and discoloration prior to administration whenever solution and container permit. Use of a final filter is recommended during administration of all parenteral solutions, where possible. Do not administer unless solution is clear and seal is intact. Test Dose: A test dose of mannitol should be given prior to instituting Osmitrol Injection (Mannitol Injection, USP) therapy for patients with marked oliguria, or those believed to have inadequate renal function. Such a test dose may be approximately 0.2 g/kg body weight (about 75 mL of a 20% solution or 100 mL of a 15% solution) infused in a period of three to five minutes to produce a urine flow of at least 30 to 50 mL/hour. If urine flow does not increase, a second test dose may be given; if there is an inadequate response, the patient should be reevaluated. Prevention of Acute Renal Failure (Oliguria): When used during cardiovascular and other types of surgery, 50 to 100 g of mannitol as a 5, 10, or 15% solution may be given. The concentration will depend upon the fluid requirements of the patient. Treatment of Oliguria: The usual dose for treatment of oliguria is 100 g administered as a 15 or 20% solution. Reduction of Intraocular Pressure: A dose of 1.5 to 2.0 g/kg as a 20% solution (7.5 to 10 mL/kg) or as a 15% solution (10 to 13 mL/kg) may be given over a period as short as 30 minutes in order to obtain a prompt and maximal effect. When used preoperatively the dose should be given one to one and one- half hours before surgery to achieve maximal reduction of intraocular pressure before operation. Reduction of Intracranial Pressure: Usually a maximum reduction in intracranial pressure in adults can be achieved with a dose of 0.25 g/kg given not more frequently than every six to eight hours. An osmotic gradient between the blood and cerebrospinal fluid of approximately 10 m0smols will yield a satisfactory reduction in intracranial pressure. Adjunctive Therapy for Intoxications: As an agent to promote diuresis in intoxications, 5%, 10%, 15% or 20% mannitol is indicated. The concentration will depend upon the fluid requirement and urinary output of the patient. Measurement of glomerular filtration rate by creatinine clearance may be useful for determination of dosage.

Because many drugs are excreted in human milk, caution should be exercised when Sodium Chloride Injection, USP is administered to a nursing woman. Pediatric Use Safety and effectiveness of Sodium Chloride Injection, USP in pediatric patients have not been established by adequate and well controlled trials, however, the use of Sodium Chloride solutions in the pediatric population is referenced in the medical literature. The warnings, precautions and adverse reactions identified in the label copy should be observed in the pediatric population. Geriatric Use Clinical studies of Sodium Chloride Injection, USP did not include sufficient numbers of subjects aged 65 and over to determine whether they respond differently from younger subjects. Other reported clinical experience has not identified differences in the responses between elderly and younger patients. In general, dose selection for an elderly patient should be cautious, usually starting at the low end of the dosing range, reflecting the greater frequency of decreased hepatic, renal, or cardiac function and of concomitant disease or drug therapy. This drug is known to be substantially excreted by the kidney, and the risk of toxic reactions to this drug may be greater in patients with impaired renal function. Because elderly patients are more likely to have decreased renal function, care should be taken in dose selection, and it may be useful to monitor renal function. Adverse Reactions Reactions which may occur because of the solution or the technique of administration include febrile response, infection at the site of injection, venous thrombosis or phlebitis extending from the site of injection, extravasation, and hypervolemia. If an adverse reaction does occur, discontinue the infusion, evaluate the patient, institute appropriate therapeutic countermeasures and save the remainder of the fluid for examination if deemed necessary.

Dextrose injections with low electrolyte concentrations should not be administered simultaneously with blood through the same administration set because of the possibility of pseudoagglutination or hemolysis. The container label for these injections bears the statement: Do not administer simultaneously with blood. The intravenous administration of Dextrose and Sodium Chloride Injection, USP can cause fluid and/or solute overloading resulting in dilution of serum electrolyte concentrations, overhydration, congested states, or pulmonary edema. The risk of dilutional states is inversely proportional to the electrolyte concentrations of the injections. The risk of solute overload causing congested states with peripheral and pulmonary edema is directly proportional to the electrolyte concentrations of the injections. Excessive administration of Dextrose and Sodium Chloride Injection, USP may result in significant hypokalemia. In patients with diminished renal function, administration of Dextrose and Sodium Chloride Injection, USP may result in sodium retention. Precautions General Do not connect flexible plastic containers of intravenous solutions in series, i.e., do not piggyback connections. Such use could result in air embolism due to residual air being drawn from one container before administration of the fluid from a secondary container is completed. Pressurizing intravenous solutions contained in flexible plastic containers to increase flow rates can result in air embolism if the residual air in the container is not fully evacuated prior to administration. Use of a vented intravenous administration set with the vent in the open position could result in air embolism. Vented intravenous administration sets with the vent in the open position should not be used with flexible plastic containers. Dextrose and Sodium Chloride Injection, USP should be used with caution in patients with overt or subclinical diabetes mellitus. Laboratory Tests Clinical evaluation and periodic laboratory determinations are necessary to monitor changes in fluid balance, electrolyte concentrations, and acid base balance during prolonged parenteral therapy or whenever the condition of the patient warrants such evaluation.

Because many drugs are excreted in human milk, caution should be exercised when Lactated Ringer's Injection, USP is administered to a nursing woman. Pediatric Use Safety and effectiveness of Lactated Ringer’s Injection, USP in pediatric patients have not been established by adequate and well controlled trials, however, the use of electrolyte solutions in the pediatric population is referenced in the medical literature. The warnings, precautions and adverse reactions identified in the label copy should be observed in the pediatric population. Geriatric Use Clinical studies of Lactated Ringer’s Injection, USP did not include sufficient numbers of subjects aged 65 and over to determine whether they respond differently from younger subjects. Other reported clinical experience has not identified differences in responses between the elderly and younger patients. In general, dose selection for an elderly patient should be cautious, usually starting at the low end of the dosing range, reflecting the greater frequency of decreased hepatic, renal, or cardiac function and concomitant disease or drug therapy. This drug is known to be substantially excreted by the kidney, and the risk of toxic reactions to this drug may be greater in patients with impaired renal function. Because elderly patients are more likely to have decreased renal function, care should be taken in dose selection, and it may be useful to monitor renal function. Adverse Reactions Allergic reactions or anaphylactoid symptoms such as localized or generalized urticaria and pruritis; periorbital, facial, and/or laryngeal edema; coughing, sneezing, and/or difficulty with breathing have been reported during administration of Lactated Ringer’s Injection, USP. The reporting frequency of these signs and symptoms is higher in women during pregnancy. Reactions which may occur because of the solution or the technique of administration include febrile response, infection at the site of injection, venous thrombosis or phlebitis extending from the site of infection, extravasation, and hypervolemia. If an adverse reaction does occur, discontinue the infusion, evaluate the patient, institute appropriate therapeutic countermeasures, and save the remainder of the fluid for examination if deemed necessary. Dosage and Administration As directed by a physician. Dosage is dependent upon the age, weight and clinical condition of the patient as well as laboratory determinations.

Dextrose injections with low electrolyte concentrations should not be administered simultaneously with blood through the same administration set because of the possibility of pseudoagglutination or hemolysis. The container label for these injections bears the statement: Do not administer simultaneously with blood. The intravenous administration of Dextrose and Sodium Chloride Injection, USP can cause fluid and/or solute overloading resulting in dilution of serum electrolyte concentrations, overhydration, congested states, or pulmonary edema. The risk of dilutional states is inversely proportional to the electrolyte concentrations of the injections. The risk of solute overload causing congested states with peripheral and pulmonary edema is directly proportional to the electrolyte concentrations of the injections. Excessive administration of Dextrose and Sodium Chloride Injection, USP may result in significant hypokalemia. In patients with diminished renal function, administration of Dextrose and Sodium Chloride Injection, USP may result in sodium retention. Precautions General Do not connect flexible plastic containers of intravenous solutions in series, i.e., do not piggyback connections. Such use could result in air embolism due to residual air being drawn from one container before administration of the fluid from a secondary container is completed. Pressurizing intravenous solutions contained in flexible plastic containers to increase flow rates can result in air embolism if the residual air in the container is not fully evacuated prior to administration. Use of a vented intravenous administration set with the vent in the open position could result in air embolism. Vented intravenous administration sets with the vent in the open position should not be used with flexible plastic containers. Dextrose and Sodium Chloride Injection, USP should be used with caution in patients with overt or subclinical diabetes mellitus. Laboratory Tests Clinical evaluation and periodic laboratory determinations are necessary to monitor changes in fluid balance, electrolyte concentrations, and acid base balance during prolonged parenteral therapy or whenever the condition of the patient warrants such evaluation.

Dextrose injections with low electrolyte concentrations should not be administered simultaneously with blood through the same administration set because of the possibility of pseudoagglutination or hemolysis. The container label for these injections bears the statement: Do not administer simultaneously with blood. The intravenous administration of Dextrose and Sodium Chloride Injection, USP can cause fluid and/or solute overloading resulting in dilution of serum electrolyte concentrations, overhydration, congested states, or pulmonary edema. The risk of dilutional states is inversely proportional to the electrolyte concentrations of the injections. The risk of solute overload causing congested states with peripheral and pulmonary edema is directly proportional to the electrolyte concentrations of the injections. Excessive administration of Dextrose and Sodium Chloride Injection, USP may result in significant hypokalemia. In patients with diminished renal function, administration of Dextrose and Sodium Chloride Injection, USP may result in sodium retention. Precautions General Do not connect flexible plastic containers of intravenous solutions in series, i.e., do not piggyback connections. Such use could result in air embolism due to residual air being drawn from one container before administration of the fluid from a secondary container is completed. Pressurizing intravenous solutions contained in flexible plastic containers to increase flow rates can result in air embolism if the residual air in the container is not fully evacuated prior to administration. Use of a vented intravenous administration set with the vent in the open position could result in air embolism. Vented intravenous administration sets with the vent in the open position should not be used with flexible plastic containers. Dextrose and Sodium Chloride Injection, USP should be used with caution in patients with overt or subclinical diabetes mellitus. Laboratory Tests Clinical evaluation and periodic laboratory determinations are necessary to monitor changes in fluid balance, electrolyte concentrations, and acid base balance during prolonged parenteral therapy or whenever the condition of the patient warrants such evaluation.

Dextrose injections with low electrolyte concentrations should not be administered simultaneously with blood through the same administration set because of the possibility of pseudoagglutination or hemolysis. The container label for these injections bears the statement: Do not administer simultaneously with blood. The intravenous administration of Dextrose and Sodium Chloride Injection, USP can cause fluid and/or solute overloading resulting in dilution of serum electrolyte concentrations, overhydration, congested states, or pulmonary edema. The risk of dilutional states is inversely proportional to the electrolyte concentrations of the injections. The risk of solute overload causing congested states with peripheral and pulmonary edema is directly proportional to the electrolyte concentrations of the injections. Excessive administration of Dextrose and Sodium Chloride Injection, USP may result in significant hypokalemia. In patients with diminished renal function, administration of Dextrose and Sodium Chloride Injection, USP may result in sodium retention. Precautions General Do not connect flexible plastic containers of intravenous solutions in series, i.e., do not piggyback connections. Such use could result in air embolism due to residual air being drawn from one container before administration of the fluid from a secondary container is completed. Pressurizing intravenous solutions contained in flexible plastic containers to increase flow rates can result in air embolism if the residual air in the container is not fully evacuated prior to administration. Use of a vented intravenous administration set with the vent in the open position could result in air embolism. Vented intravenous administration sets with the vent in the open position should not be used with flexible plastic containers. Dextrose and Sodium Chloride Injection, USP should be used with caution in patients with overt or subclinical diabetes mellitus.

The warnings, precautions and adverse reactions identified in the label copy should be observed in the pediatric population. Geriatric Use Clinical studies of Sodium Lactate Injection, USP did not include sufficient numbers of subjects aged 65 and over to determine whether they respond differently from younger subjects. Other reported clinical experience has not identified differences in responses between the elderly and younger patients. In general, dose selection for an elderly patient should be cautious, usually starting at the low end of the dosing range, reflecting the greater frequency of decreased hepatic, renal, or cardiac function, and of concomitant disease or drug therapy. This drug is known to be substantially excreted by the kidney, and the risk of toxic reactions to this drug may be greater in patients with impaired renal function. Because elderly patients are more likely to have decreased renal function, care should be taken in dose selection, and it may be useful to monitor renal function. Adverse Reactions Reactions which may occur because of the solution or the technique of administration include febrile response, infection at the site of injection, venous thrombosis or phlebitis extending from the site of injection, extravasation and hypervolemia. If an adverse reaction does occur, discontinue the infusion, evaluate the patient, institute appropriate therapeutic countermeasures, and save the remainder of the fluid for examination if deemed necessary. Dosage and Administration As directed by a physician. Dosage is dependent upon the age, weight and clinical condition of the patient as well as laboratory determinations. Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration whenever solution and container permit. Use of a final filter is recommended during administration of all parenteral solutions, where possible. Do not administer unless solution is clear and seal is intact.

The risk of dilutional states is inversely proportional to the electrolyte concentrations of the injection. The risk of solute overload causing congested states with peripheral and pulmonary edema is directly proportional to the electrolyte concentrations of the injection. In patients with diminished renal function, administration of Ringer’s Injection, USP may result in sodium or potassium retention. Precautions General Do not connect flexible plastic containers of intravenous solutions in series, i.e., do not piggyback connections. Such use could result in air embolism due to residual air being drawn from one container before administration of the fluid from a secondary container is completed. Pressurizing intravenous solutions contained in flexible plastic containers to increase flow rates can result in air embolism if the residual air in the container is not fully evacuated prior to administration. Use of a vented intravenous administration set with the vent in the open position could result in air embolism. Vented intravenous administration sets with the vent in the open position should not be used with flexible plastic containers. Laboratory Tests Clinical evaluation and periodic laboratory determinations are necessary to monitor changes in fluid balance, electrolyte concentrations, and acid base balance during prolonged parenteral therapy or whenever the condition of the patient warrants such evaluation.

It is capable of inducing diuresis depending on the clinical condition of the patient. Indications and Usage Ringer’s Injection, USP is indicated as a source of water and electrolytes. Contraindications None known Warnings Ringer’s Injection, USP should be used with great care, if at all, in patients with congestive heart failure, severe renal insufficiency, and in clinical states in which there exists edema with sodium retention. Ringer’s Injection, USP should be used with great care, if at all, in patients with hyperkalemia, severe renal failure, and in conditions in which potassium retention is present. Ringer’s Injection, USP should not be administered simultaneously with blood through the same administration set because of the likelihood of coagulation. The intravenous administration of Ringer’s Injection, USP can cause fluid and/or solute overloading resulting in dilution of serum electrolyte concentrations, overhydration, congested states, or pulmonary edema. The risk of dilutional states is inversely proportional to the electrolyte concentrations of the injection. The risk of solute overload causing congested states with peripheral and pulmonary edema is directly proportional to the electrolyte concentrations of the injection. In patients with diminished renal function, administration of Ringer’s Injection, USP may result in sodium or potassium retention. Precautions General Do not connect flexible plastic containers of intravenous solutions in series, i.e., do not piggyback connections. Such use could result in air embolism due to residual air being drawn from one container before administration of the fluid from a secondary container is completed. Pressurizing intravenous solutions contained in flexible plastic containers to increase flow rates can result in air embolism if the residual air in the container is not fully evacuated prior to administration.

Other reported clinical experience has not identified differences in responses between the elderly and younger patients. In general, dose selection for an elderly patient should be cautious, usually starting at the low end of the dosing range, reflecting the greater frequency of decreased hepatic, renal, or cardiac function, and of concomitant disease or drug therapy. This drug is known to be substantially excreted by the kidney, and the risk of toxic reactions to this drug may be greater in patients with impaired renal function. Because elderly patients are more likely to have decreased renal function, care should be taken in dose selection, and it may be useful to monitor renal function. Adverse Reactions Reactions which may occur because of the solution or the technique of administration include febrile response, infection at the site of injection, venous thrombosis or phlebitis extending from the site of injection, extravasation and hypervolemia. If an adverse reaction does occur, discontinue the infusion, evaluate the patient, institute appropriate therapeutic countermeasures, and save the remainder of the fluid for examination if deemed necessary. Dosage and Administration As directed by a physician. Dosage is dependent upon the age, weight and clinical condition of the patient as well as laboratory determinations.

Dextrose injections with low electrolyte concentrations should not be administered simultaneously with blood through the same administration set because of the possibility of pseudoagglutination or hemolysis. The container label for these injections bears the statement: Do not administer simultaneously with blood. The intravenous administration of Dextrose and Sodium Chloride Injection, USP can cause fluid and/or solute overloading resulting in dilution of serum electrolyte concentrations, overhydration, congested states, or pulmonary edema. The risk of dilutional states is inversely proportional to the electrolyte concentrations of the injections. The risk of solute overload causing congested states with peripheral and pulmonary edema is directly proportional to the electrolyte concentrations of the injections. Excessive administration of Dextrose and Sodium Chloride Injection, USP may result in significant hypokalemia. In patients with diminished renal function, administration of Dextrose and Sodium Chloride Injection, USP may result in sodium retention. Precautions General Do not connect flexible plastic containers of intravenous solutions in series, i.e., do not piggyback connections. Such use could result in air embolism due to residual air being drawn from one container before administration of the fluid from a secondary container is completed. Pressurizing intravenous solutions contained in flexible plastic containers to increase flow rates can result in air embolism if the residual air in the container is not fully evacuated prior to administration. Use of a vented intravenous administration set with the vent in the open position could result in air embolism. Vented intravenous administration sets with the vent in the open position should not be used with flexible plastic containers. Dextrose and Sodium Chloride Injection, USP should be used with caution in patients with overt or subclinical diabetes mellitus. Laboratory Tests Clinical evaluation and periodic laboratory determinations are necessary to monitor changes in fluid balance, electrolyte concentrations, and acid base balance during prolonged parenteral therapy or whenever the condition of the patient warrants such evaluation.

Dextrose injections with low electrolyte concentrations should not be administered simultaneously with blood through the same administration set because of the possibility of pseudoagglutination or hemolysis. The container label for these injections bears the statement: Do not administer simultaneously with blood. The intravenous administration of Dextrose and Sodium Chloride Injection, USP can cause fluid and/or solute overloading resulting in dilution of serum electrolyte concentrations, overhydration, congested states, or pulmonary edema. The risk of dilutional states is inversely proportional to the electrolyte concentrations of the injections. The risk of solute overload causing congested states with peripheral and pulmonary edema is directly proportional to the electrolyte concentrations of the injections. Excessive administration of Dextrose and Sodium Chloride Injection, USP may result in significant hypokalemia. In patients with diminished renal function, administration of Dextrose and Sodium Chloride Injection, USP may result in sodium retention. Precautions General Do not connect flexible plastic containers of intravenous solutions in series, i.e., do not piggyback connections. Such use could result in air embolism due to residual air being drawn from one container before administration of the fluid from a secondary container is completed. Pressurizing intravenous solutions contained in flexible plastic containers to increase flow rates can result in air embolism if the residual air in the container is not fully evacuated prior to administration. Use of a vented intravenous administration set with the vent in the open position could result in air embolism. Vented intravenous administration sets with the vent in the open position should not be used with flexible plastic containers. Dextrose and Sodium Chloride Injection, USP should be used with caution in patients with overt or subclinical diabetes mellitus. Laboratory Tests Clinical evaluation and periodic laboratory determinations are necessary to monitor changes in fluid balance, electrolyte concentrations, and acid base balance during prolonged parenteral therapy or whenever the condition of the patient warrants such evaluation.

Caution should be exercised when administering this drug during labor and delivery. Nursing Mothers It is not known whether this drug is excreted in human milk. Because many drugs are excreted in human milk, caution should be exercised when PLASMA-LYTE 148 Injection (Multiple Electrolytes Injection, Type 1, USP) is administered to a nursing woman. Pediatric Use Safety and effectiveness of PLASMA-LYTE 148 Injection (Multiple Electrolytes Injection, Type 1, USP) in pediatric patients have not been established by adequate and well controlled trials, however, the use of electrolyte solutions in the pediatric population is referenced in the medical literature. The warnings, precautions and adverse reactions identified in the label copy should be observed in the pediatric population. Geriatric Use Clinical studies of PLASMA-LYTE 148 Injection (Multiple Electrolytes Injection, Type 1, USP) did not include sufficient numbers of subjects aged 65 and over to determine whether they respond differently from younger subjects. Other reported clinical experience has not identified differences in responses between the elderly and younger patients. In general, dose selection for an elderly patient should be cautious, usually starting at the low end of the dosing range, reflecting the greater frequency of decreased hepatic, renal, or cardiac function, and of concomitant disease or drug therapy. This drug is known to be substantially excreted by the kidney, and the risk of toxic reactions to this drug may be greater in patients with impaired renal function. Because elderly patients are more likely to have decreased renal function, care should be taken in dose selection, and it may be useful to monitor renal function. Adverse Reactions Reactions which may occur because of the solution or the technique of administration include febrile response, infection at the site of injection, venous thrombosis or phlebitis extending from the site of injection, extravasation and hypervolemia. If an adverse reaction does occur, discontinue the infusion, evaluate the patient, institute appropriate therapeutic countermeasures, and save the remainder of the fluid for examination if deemed necessary.

The intravenous administration of PLASMA-LYTE 56 and 5% Dextrose Injection (Multiple Electrolytes and Dextrose Injection, Type 1, USP) can cause fluid and/or solute overloading resulting in dilution of serum electrolyte concentrations, overhydration, congested states, or pulmonary edema. The risk of dilutional states is inversely proportional to the electrolyte concentrations of the injection. The risk of solute overload causing congested states with peripheral and pulmonary edema is directly proportional to the electrolyte concentrations of the injection. In patients with diminished renal function, administration of PLASMA-LYTE 56 and 5% Dextrose Injection (Multiple Electrolytes and Dextrose Injection, Type 1, USP) may result in sodium or potassium retention. Precautions General Do not connect flexible plastic containers of intravenous solutions in series, i.e., do not piggyback connections. Such use could result in air embolism due to residual air being drawn from one container before administration of the fluid from a secondary container is completed. Pressurizing intravenous solutions contained in flexible plastic containers to increase flow rates can result in air embolism if the residual air in the container is not fully evacuated prior to administration. Use of a vented intravenous administration set with the vent in the open position could result in air embolism. Vented intravenous administration sets with the vent in the open position should not be used with flexible plastic containers. PLASMA-LYTE 56 and 5% Dextrose Injection (Multiple Electrolytes and Dextrose Injection, Type 1, USP) should be used with caution. Excess administration may result in metabolic alkalosis. PLASMA-LYTE 56 and 5% Dextrose Injection (Multiple Electrolytes and Dextrose Injection, Type 1, USP) should be used with caution in patients with overt or subclinical diabetes mellitus. Laboratory Tests Clinical evaluation and periodic laboratory determinations are necessary to monitor changes in fluid balance, electrolyte concentrations, and acid base balance during prolonged parenteral therapy or whenever the condition of the patient warrants such evaluation. Drug Interactions Caution must be exercised in the administration of PLASMA-LYTE 56 and 5% Dextrose Injection (Multiple Electrolytes and Dextrose Injection, Type 1, USP) to patients receiving corticosteroids or corticotropin.

This drug is known to be substantially excreted by the kidney, and the risk of toxic reactions to this drug may be greater in patients with impaired renal function. Because elderly patients are more likely to have decreased renal function, care should be taken in dose selection, and it may be useful to monitor renal function. Adverse Reactions Reactions which may occur because of the solution or the technique of administration include febrile response, infection at the site of injection, venous thrombosis or phlebitis extending from the site of injection, extravasation, and hypervolemia. If an adverse reaction does occur, discontinue the infusion, evaluate the patient, institute appropriate therapeutic countermeasures, and save the remainder of the fluid for examination if deemed necessary. Dosage and Administration As directed by a physician. Dosage is dependent upon the age, weight and clinical condition of the patient as well as laboratory determinations. Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration whenever solution and container permit. Do not administer unless solution is clear and seal is intact. All injections in AVIVA plastic containers are intended for intravenous administration using sterile equipment. As reported in the literature, the dosage and constant infusion rate of intravenous dextrose must be selected with caution in pediatric patients, particularly neonates and low weight infants, because of the increased risk of hyperglycemia/hypoglycemia. Additives may be incompatible. Complete information is not available. Those additives known to be incompatible should not be used. Consult with pharmacist, if available. If, in the informed judgment of the physician, it is deemed advisable to introduce additives, use aseptic technique. Mix thoroughly when additives have been introduced.

PLASMA-LYTE M and 5% Dextrose Injection (Multiple Electrolytes and Dextrose Injection, Type 2, USP) should not be administered simultaneously with blood through the same administration set because of the likelihood of coagulation. The intravenous administration of PLASMA-LYTE M and 5% Dextrose Injection (Multiple Electrolytes and Dextrose Injection, Type 2, USP) can cause fluid and/or solute overloading resulting in dilution of serum electrolyte concentrations, overhydration, congested states, or pulmonary edema. The risk of dilutional states is inversely proportional to the electrolyte concentrations of the injection. The risk of solute overload causing congested states with peripheral and pulmonary edema is directly proportional to the electrolyte concentrations of the injection. In patients with diminished renal function, administration of PLASMA-LYTE M and 5% Dextrose Injection (Multiple Electrolytes and Dextrose Injection, Type 2, USP) containing sodium or potassium ions may result in sodium or potassium retention. PLASMA-LYTE M and 5% Dextrose Injection (Multiple Electrolytes and Dextrose Injection, Type 2, USP) is not for use in the treatment of lactic acidosis. Precautions General Do not connect flexible plastic containers of intravenous solutions in series, i.e., do not piggyback connections. Such use could result in air embolism due to residual air being drawn from one container before administration of the fluid from a secondary container is completed. Pressurizing intravenous solutions contained in flexible plastic containers to increase flow rates can result in air embolism if the residual air in the container is not fully evacuated prior to administration. Use of a vented intravenous administration set with the vent in the open position could result in air embolism. Vented intravenous administration sets with the vent in the open position should not be used with flexible plastic containers. PLASMA-LYTE M and 5% Dextrose Injection (Multiple Electrolytes and Dextrose Injection, Type 2, USP) should be used with caution. Excess administration may result in metabolic alkalosis. PLASMA-LYTE M and 5% Dextrose Injection (Multiple Electrolytes and Dextrose Injection, Type 2, USP) should be used with caution in patients with overt or subclinical diabetes mellitus.

Geriatric Use Clinical studies of PLASMA-LYTE M and 5% Dextrose Injection (Multiple Electrolytes and Dextrose Injection, Type 2, USP) did not include sufficient numbers of subjects aged 65 and over to determine whether they respond differently from younger subjects. Other reported clinical experience has not identified differences in responses between the elderly and younger patients. In general, dose selection for an elderly patient should be cautious, usually starting at the low end of the dosing range, reflecting the greater frequency of decreased hepatic, renal, or cardiac function, and of concomitant disease or drug therapy. This drug is known to be substantially excreted by the kidney, and the risk of toxic reactions to this drug may be greater in patients with impaired renal function. Because elderly patients are more likely to have decreased renal function, care should be taken in dose selection, and it may be useful to monitor renal function. Adverse Reactions Reactions which may occur because of the solution or the technique of administration include febrile response, infection at the site of injection, venous thrombosis or phlebitis extending from the site of injection, extravasation, and hypervolemia. If an adverse reaction does occur, discontinue the infusion, evaluate the patient, institute appropriate therapeutic countermeasures, and save the remainder of the fluid for examination if deemed necessary. Dosage and Administration As directed by a physician. Dosage is dependent upon the age, weight and clinical condition of the patient as well as laboratory determinations. Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration whenever solution and container permit. Do not administer unless solution is clear and seal is intact. All injections in AVIVA plastic containers are intended for intravenous administration using sterile equipment. As reported in the literature, the dosage and constant infusion rate of intravenous dextrose must be selected with caution in pediatric patients, particularly neonates and low weight infants, because of the increased risk of hyperglycemia/hypoglycemia.

Caution should be exercised when administering this drug during labor and delivery. Nursing Mothers It is not known whether this drug is excreted in human milk. Because many drugs are excreted in human milk, caution should be exercised when PLASMA-LYTE R Injection (Multiple Electrolytes Injection, Type 2, USP) is administered to a nursing woman. Pediatric Use Safety and effectiveness of PLASMA-LYTE R Injection (Multiple Electrolytes Injection, Type 2, USP) in pediatric patients have not been established by adequate and well controlled trials, however, the use of electrolyte solutions in the pediatric population is referenced in the medical literature. The warnings, precautions and adverse reactions identified in the label copy should be observed in the pediatric population. Geriatric Use Clinical studies of PLASMA-LYTE R Injection (Multiple Electrolytes Injection, Type 2, USP) did not include sufficient numbers of subjects aged 65 and over to determine whether they respond differently from younger subjects. Other reported clinical experience has not identified differences in responses between the elderly and younger patients. In general, dose selection for an elderly patient should be cautious, usually starting at the low end of the dosing range, reflecting the greater frequency of decreased hepatic, renal, or cardiac function, and of concomitant disease or drug therapy. This drug is known to be substantially excreted by the kidney, and the risk of toxic reactions to this drug may be greater in patients with impaired renal function. Because elderly patients are more likely to have decreased renal function, care should be taken in dose selection, and it may be useful to monitor renal function. Adverse Reactions Reactions which may occur because of the solution or the technique of administration include febrile response, infection at the site of injection, venous thrombosis or phlebitis extending from the site of injection, extravasation and hypervolemia. If an adverse reaction does occur, discontinue the infusion, evaluate the patient, institute appropriate therapeutic countermeasures and save the remainder of the fluid for examination if deemed necessary. Dosage and Administration As directed by a physician. Dosage is dependent upon the age, weight and clinical condition of the patient as well as laboratory determinations. Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration whenever solution and container permit.

The intravenous administration of 5% Dextrose and Electrolyte No. 48 Injection (Multiple Electrolytes and Dextrose Injection, Type 1, USP) can cause fluid and/or solute overloading resulting in dilution of serum electrolyte concentrations, overhydration, congested states, or pulmonary edema. The risk of dilutional states is inversely proportional to the electrolyte concentrations of the injection. The risk of solute overload causing congested states with peripheral and pulmonary edema is directly proportional to the electrolyte concentrations of the injection. In patients with diminished renal function, administration of 5% Dextrose and Electrolyte No. 48 Injection (Multiple Electrolytes and Dextrose Injection, Type 1, USP) may result in sodium or potassium retention. 5% Dextrose and Electrolyte No. 48 Injection (Multiple Electrolytes and Dextrose Injection, Type 1, USP) is not for use in the treatment of lactic acidosis. Precautions General Do not connect flexible plastic containers of intravenous solutions in series, i.e., do not piggyback connections. Such use could result in air embolism due to residual air being drawn from one container before administration of the fluid from a secondary container is completed. Pressurizing intravenous solutions contained in flexible plastic containers to increase flow rates can result in air embolism if the residual air in the container is not fully evacuated prior to administration. Use of a vented intravenous administration set with the vent in the open position could result in air embolism. Vented intravenous administration sets with the vent in the open position should not be used with flexible plastic containers. Do not administer simultaneously with blood. 5% Dextrose and Electrolyte No. 48 Injection (Multiple Electrolytes and Dextrose Injection, Type 1, USP) should be used with caution. Excess administration may result in metabolic alkalosis. 5% Dextrose and Electrolyte No. 48 Injection (Multiple Electrolytes and Dextrose Injection, Type 1, USP) should be used with caution in patients with overt or subclinical diabetes mellitus. Laboratory Tests Clinical evaluation and periodic laboratory determinations are necessary to monitor changes in fluid balance, electrolyte concentrations, and acid base balance during prolonged parenteral therapy or whenever the condition of the patient warrants such evaluation.

The risk of dilutional states is inversely proportional to the electrolyte concentrations of the injection. The risk of solute overload causing congested states with peripheral and pulmonary edema is directly proportional to the electrolyte concentrations of the injection. In patients with diminished renal function, administration of Potassium Chloride in 5% Dextrose Injection, USP may result in potassium retention. In very low birth weight infants, excessive or rapid administration of dextrose injection may result in increased serum osmolality and possible intracerebral hemorrhage. Potassium salts should never be administered by IV push. Precautions General Do not connect flexible plastic containers of intravenous solutions in series, i.e., do not piggyback connections. Such use could result in air embolism due to residual air being drawn from one container before administration of the fluid from a secondary container is completed. Pressurizing intravenous solutions contained in flexible plastic containers to increase flow rates can result in air embolism if the residual air in the container is not fully evacuated prior to administration. Use of a vented intravenous administration set with the vent in the open position could result in air embolism. Vented intravenous administration sets with the vent in the open position should not be used with flexible plastic containers. For patients receiving potassium supplement at greater than maintenance rates, frequent monitoring of serum potassium levels and serial EKGs are recommended. Potassium Chloride in 5% Dextrose Injection, USP should be used with caution in patients with overt or subclinical diabetes mellitus. Laboratory Tests Clinical evaluation and periodic laboratory determinations are necessary to monitor changes in fluid balance, electrolyte concentrations, and acid base balance during prolonged parenteral therapy or whenever the condition of the patient warrants such evaluation. Drug Interactions Studies have not been conducted to evaluate drug/drug or drug/food interactions with Potassium Chloride in 5% Dextrose Injection, USP. This label may not be the latest approved by FDA.

Pregnancy: Teratogenic Effects Pregnancy Category C. Animal reproduction studies have not been conducted with Potassium Chloride in 5% Dextrose Injection, USP. It is also not known whether Potassium Chloride in 5% Dextrose Injection, USP can cause fetal harm when administered to a pregnant woman or can affect reproduction capacity. Potassium Chloride in 5% Dextrose Injection, USP should be given to a pregnant woman only if clearly needed. Labor and Delivery Studies have not been conducted to evaluate the effects of Potassium Chloride in 5% Dextrose Injection, USP on labor and delivery. Caution should be exercised when administering this drug labor and delivery. Nursing Mothers It is not known whether this drug is excreted in human milk. Because many drugs are excreted in human milk, caution should be exercised when Potassium Chloride in 5% Dextrose Injection, USP is administered to a nursing mother. Pediatric Use Safety and effectiveness of Potassium Chloride in 5% Dextrose Injection in pediatric patients have not been established by adequate and well-controlled studies. However, the use of potassium chloride injection in pediatric patients to treat potassium deficiency states when oral replacement therapy is not feasible is referenced in the medical literature. Dextrose is safe and effective for the stated indications in pediatric patients (see Indication and Usage). As reported in the literature, the dosage selection and constant infusion rate of intravenous dextrose must be selected with caution in pediatric patients, particularly neonates and low birth weight infants, because of the increased risk of hyperglycemia/hypoglycemia. Frequent monitoring of serum glucose concentrations is required when dextrose is prescribed to pediatric patients, particularly neonates and low birth weight infants. Geriatric Use Clinical studies of Potassium Chloride in 5% Dextrose Injection, USP did not include sufficient numbers of subjects aged 65 and over to determine whether they respond differently from younger subjects. Other reported clinical experience has not identified differences in the responses between elderly and younger patients. In general, dose selection for an elderly patient should be cautious, usually starting at the low end of the dosing range, reflecting the greater frequency of decreased hepatic, renal, or cardiac function and of concomitant disease or drug therapy.

Potassium Chloride in Sodium Chloride Injection, USP should be used with great care, if at all, in patients with hyperkalemia, severe renal failure and in conditions in which potassium retention is present. The intravenous administration of Potassium Chloride in Sodium Chloride Injection, USP can cause fluid and/or solute overloading resulting in dilution of serum electrolyte concentrations, overhydration, congested states or pulmonary edema. The risk of dilutional states is inversely proportional to the electrolyte concentrations of the injection. The risk of solute overload causing congested states with peripheral and pulmonary edema is directly proportional to the electrolyte concentrations of the injection. In patients with diminished renal function, administration of Potassium Chloride in Sodium Chloride Injection, USP may result in sodium or potassium retention. Potassium salts should never be administered by IV push. Precautions General Do not connect flexible plastic containers of intravenous solutions in series, i.e., do not piggyback connections. Such use could result in air embolism due to residual air being drawn from one container before administration of the fluid from a secondary container is completed. Pressurizing intravenous solutions contained in flexible plastic containers to increase flow rates can result in air embolism if the residual air in the container is not fully evacuated prior to administration.

However, the use of potassium chloride injection in pediatric patients to treat potassium deficiency states when oral replacement therapy is not feasible is referenced in the medical literature. Geriatric Use Clinical studies of Potassium Chloride in Sodium Chloride Injection, USP did not include sufficient numbers of subjects aged 65 and over to determine whether they respond differently from younger subjects. Other reported clinical experience has not identified differences in the responses between elderly and younger patients. In general, dose selection for an elderly patient should be cautious, usually starting at the low end of the dosing range, reflecting the greater frequency of decreased hepatic, renal, or cardiac function and of concomitant disease or drug therapy. This drug is known to be substantially excreted by the kidney, and the risk of toxic reactions to this drug may be greater in patients with impaired renal function. Because elderly patients are more likely to have decreased renal function, care should be taken in dose selection, and it may be useful to monitor renal function. Adverse Reactions Reactions which may occur because of the solution or the technique of administration include febrile response, infection at the site of injection, venous thrombosis or phlebitis extending from the site of injection, extravasation and hypervolemia. If an adverse reaction does occur, discontinue the infusion, evaluate the patient, institute appropriate therapeutic countermeasures and save the remainder of the fluid for examination if deemed necessary. Dosage and Administration As directed by a physician. Dosage is dependent upon the age, weight and clinical condition of the patient as well as laboratory determinations. Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration whenever solution and container permit. Use of final filter is recommended during administration of all parenteral solutions, where possible. Do not administer unless solution is clear and seal is intact. All injections in AVIVA plastic containers are intended for intravenous administration using sterile equipment. Additives may be incompatible. Complete information is not available. Those additives known to be incompatible should not be used. Consult with pharmacist, if available.

Potassium Chloride in 5% Dextrose and Sodium Chloride Injection, USP should be used with great care, if at all, in patients with hyperkalemia, severe renal failure, and in conditions in which potassium retention is present. Injections containing carbohydrates with low electrolyte concentration should not be administered simultaneously with blood through the same administration set because of the possibility of pseudoagglutination or hemolysis. The container label for these injections bears the statement: Do not administer simultaneously with blood. The intravenous administration of Potassium Chloride in 5% Dextrose and Sodium Chloride Injection, USP can cause fluid and/or solute overloading resulting in dilution of serum electrolyte concentrations, overhydration, congested states or pulmonary edema. The risk of dilutional states is inversely proportional to the electrolyte concentrations of the injection. The risk of solute overload causing congested states with peripheral and pulmonary edema is directly proportional to the electrolyte concentrations of the injection. In patients with diminished renal function, administration of Potassium Chloride in 5% Dextrose and Sodium Chloride Injection, USP may result in sodium or potassium retention. In very low birth weight infants, excessive or rapid administration of dextrose injection may result in increased serum osmolality and possible intracerebral hemorrhage. Potassium salts should never be administered by IV push. Precautions General Do not connect flexible plastic containers of intravenous solutions in series, i.e., do not piggyback connections. Such use could result in air embolism due to residual air being drawn from one container before administration of the fluid from a secondary container is completed. Pressurizing intravenous solutions contained in flexible plastic containers to increase flow rates can result in air embolism if the residual air in the container is not fully evacuated prior to administration. Use of a vented intravenous administration set with the vent in the open position could result in air embolism. Vented intravenous administration sets with the vent in the open position should not be used with flexible plastic containers.

As reported in the literature, the dosage selection and constant infusion rate of intravenous dextrose must be selected with caution in pediatric patients, particularly neonates and low birth weight infants, because of the increased risk of hyperglycemia/hypoglycemia. Frequent monitoring of serum glucose concentrations is required when dextrose is prescribed to pediatric patients, particularly neonates and low birth weight infants. Geriatric Use Clinical studies of Potassium Chloride in 5% Dextrose and Sodium Chloride Injection, USP did not include sufficient numbers of subjects aged 65 and over to determine whether they respond differently from younger subjects. Other reported clinical experience has not identified differences in the responses between elderly and younger patients. In general, dose selection for an elderly patient should be cautious, usually starting at the low end of the dosing range, reflecting the greater frequency of decreased hepatic, renal, or cardiac function and of concomitant disease or drug therapy. This drug is known to be substantially excreted by the kidney, and the risk of toxic reactions to this drug may be greater in patients with impaired renal function. Because elderly patients are more likely to have decreased renal function, care should be taken in dose selection, and it may be useful to monitor renal function. Adverse Reactions Reactions which may occur because of the solution or the technique of administration include febrile response, infection at the site of injection, venous thrombosis or phlebitis extending from the site of injection, extravasation, and hypervolemia. If an adverse reaction does occur, discontinue the infusion, evaluate the patient, institute appropriate therapeutic countermeasures, and save the remainder of the fluid for examination if deemed necessary. Dosage and Administration As directed by a physician. Dosage is dependent upon the age, weight and clinical condition of the patient as well as laboratory determinations. Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration whenever solution and container permit. Use of a final filter is recommended during administration of all parenteral solutions, where possible. Do not administer unless solution is clear and seal is intact. All injections in AVIVA plastic containers are intended for intravenous administration using sterile equipment. Additives may be incompatible. Complete information is not available.

Potassium Chloride in 5% Dextrose and Sodium Chloride Injection, USP should be used with great care, if at all, in patients with hyperkalemia, severe renal failure, and in conditions in which potassium retention is present. Injections containing carbohydrates with low electrolyte concentration should not be administered simultaneously with blood through the same administration set because of the possibility of pseudoagglutination or hemolysis. The container label for these injections bears the statement: Do not administer simultaneously with blood. The intravenous administration of Potassium Chloride in 5% Dextrose and Sodium Chloride Injection, USP can cause fluid and/or solute overloading resulting in dilution of serum electrolyte concentrations, overhydration, congested states or pulmonary edema. The risk of dilutional states is inversely proportional to the electrolyte concentrations of the injection. The risk of solute overload causing congested states with peripheral and pulmonary edema is directly proportional to the electrolyte concentrations of the injection. In patients with diminished renal function, administration of Potassium Chloride in 5% Dextrose and Sodium Chloride Injection, USP may result in sodium or potassium retention. In very low birth weight infants, excessive or rapid administration of dextrose injection may result in increased serum osmolality and possible intracerebral hemorrhage. Potassium salts should never be administered by IV push. Precautions General Do not connect flexible plastic containers of intravenous solutions in series, i.e., do not piggyback connections. Such use could result in air embolism due to residual air being drawn from one container before administration of the fluid from a secondary container is completed. Pressurizing intravenous solutions contained in flexible plastic containers to increase flow rates can result in air embolism if the residual air in the container is not fully evacuated prior to administration. Use of a vented intravenous administration set with the vent in the open position could result in air embolism. Vented intravenous administration sets with the vent in the open position should not be used with flexible plastic containers. For patients receiving potassium supplement of greater then maintenance rates, frequent monitoring of serum potassium levels and serial EKGs are recommended.

As reported in the literature, the dosage selection and constant infusion rate of intravenous dextrose must be selected with caution in pediatric patients, particularly neonates and low birth weight infants, because of the increased risk of hyperglycemia/hypoglycemia. Frequent monitoring of serum glucose concentrations is required when dextrose is prescribed to pediatric patients, particularly neonates and low birth weight infants. Geriatric Use Clinical studies of Potassium Chloride in 5% Dextrose and Sodium Chloride Injection, USP did not include sufficient numbers of subjects aged 65 and over to determine whether they respond differently from younger subjects. Other reported clinical experience has not identified differences in the responses between elderly and younger patients. In general, dose selection for an elderly patient should be cautious, usually starting at the low end of the dosing range, reflecting the greater frequency of decreased hepatic, renal, or cardiac function and of concomitant disease or drug therapy. This drug is known to be substantially excreted by the kidney, and the risk of toxic reactions to this drug may be greater in patients with impaired renal function. Because elderly patients are more likely to have decreased renal function, care should be taken in dose selection, and it may be useful to monitor renal function. Adverse Reactions Reactions which may occur because of the solution or the technique of administration include febrile response, infection at the site of injection, venous thrombosis or phlebitis extending from the site of injection, extravasation, and hypervolemia. If an adverse reaction does occur, discontinue the infusion, evaluate the patient, institute appropriate therapeutic countermeasures, and save the remainder of the fluid for examination if deemed necessary. Dosage and Administration As directed by a physician. Dosage is dependent upon the age, weight and clinical condition of the patient as well as laboratory determinations. Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration whenever solution and container permit. Use of a final filter is recommended during administration of all parenteral solutions, where possible. Do not administer unless solution is clear and seal is intact. All injections in AVIVA plastic containers are intended for intravenous administration using sterile equipment. Additives may be incompatible. Complete information is not available. Those additives known to be incompatible should not be used. Consult with pharmacist, if available. If, in the informed judgment of the physician, it is deemed advisable to introduce additives, use aseptic technique. Mix thoroughly when additives have been introduced. Do not store solutions containing additives. This label may not be the latest approved by FDA.

Potassium Chloride in 5% Dextrose and Sodium Chloride Injection, USP should be used with great care, if at all, in patients with hyperkalemia, severe renal failure, and in conditions in which potassium retention is present. Injections containing carbohydrates with low electrolyte concentration should not be administered simultaneously with blood through the same administration set because of the possibility of pseudoagglutination or hemolysis. The container label for these injections bears the statement: Do not administer simultaneously with blood. The intravenous administration of Potassium Chloride in 5% Dextrose and Sodium Chloride Injection, USP can cause fluid and/or solute overloading resulting in dilution of serum electrolyte concentrations, overhydration, congested states or pulmonary edema. The risk of dilutional states is inversely proportional to the electrolyte concentrations of the injection. The risk of solute overload causing congested states with peripheral and pulmonary edema is directly proportional to the electrolyte concentrations of the injection. In patients with diminished renal function, administration of Potassium Chloride in 5% Dextrose and Sodium Chloride Injection, USP may result in sodium or potassium retention. In very low birth weight infants, excessive or rapid administration of dextrose injection may result in increased serum osmolality and possible intracerebral hemorrhage. Potassium salts should never be administered by IV push. Precautions General Do not connect flexible plastic containers of intravenous solutions in series, i.e., do not piggyback connections. Such use could result in air embolism due to residual air being drawn from one container before administration of the fluid from a secondary container is completed. Pressurizing intravenous solutions contained in flexible plastic containers to increase flow rates can result in air embolism if the residual air in the container is not fully evacuated prior to administration. Use of a vented intravenous administration set with the vent in the open position could result in air embolism. Vented intravenous administration sets with the vent in the open position should not be used with flexible plastic containers. For patients receiving potassium supplement of greater then maintenance rates, frequent monitoring of serum potassium levels and serial EKGs are recommended.

As reported in the literature, the dosage selection and constant infusion rate of intravenous dextrose must be selected with caution in pediatric patients, particularly neonates and low birth weight infants, because of the increased risk of hyperglycemia/hypoglycemia. Frequent monitoring of serum glucose concentrations is required when dextrose is prescribed to pediatric patients, particularly neonates and low birth weight infants. Geriatric Use Clinical studies of Potassium Chloride in 5% Dextrose and Sodium Chloride Injection, USP did not include sufficient numbers of subjects aged 65 and over to determine whether they respond differently from younger subjects. Other reported clinical experience has not identified differences in the responses between elderly and younger patients. In general, dose selection for an elderly patient should be cautious, usually starting at the low end of the dosing range, reflecting the greater frequency of decreased hepatic, renal, or cardiac function and of concomitant disease or drug therapy. This drug is known to be substantially excreted by the kidney, and the risk of toxic reactions to this drug may be greater in patients with impaired renal function. Because elderly patients are more likely to have decreased renal function, care should be taken in dose selection, and it may be useful to monitor renal function. Adverse Reactions Reactions which may occur because of the solution or the technique of administration include febrile response, infection at the site of injection, venous thrombosis or phlebitis extending from the site of injection, extravasation, and hypervolemia. If an adverse reaction does occur, discontinue the infusion, evaluate the patient, institute appropriate therapeutic countermeasures, and save the remainder of the fluid for examination if deemed necessary. Dosage and Administration As directed by a physician. Dosage is dependent upon the age, weight and clinical condition of the patient as well as laboratory determinations. Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration whenever solution and container permit. Use of a final filter is recommended during administration of all parenteral solutions, where possible. Do not administer unless solution is clear and seal is intact. All injections in AVIVA plastic containers are intended for intravenous administration using sterile equipment. Additives may be incompatible. Complete information is not available. Those additives known to be incompatible should not be used. Consult with pharmacist, if available. If, in the informed judgment of the physician, it is deemed advisable to introduce additives, use aseptic technique. Mix thoroughly when additives have been introduced. Do not store solutions containing additives. This label may not be the latest approved by FDA.

It is capable of inducing diuresis depending on the clinical condition of the patient. Indications and Usage 3% and 5% Sodium Chloride Injection, USP is indicated as a source of water and electrolytes. Contraindications None known Warnings 3% and 5% Sodium Chloride Injection, USP is strongly hypertonic and may cause vein damage. 3% and 5% Sodium Chloride Injection, USP should be used with great care, if at all, in patients with congestive heart failure, severe renal insufficiency, and in clinical states in which there exists edema with sodium retention. In patients with diminished renal function, administration of 3% and 5% Sodium Chloride Injection, USP may result in sodium retention. Precautions General Do not connect flexible plastic containers of intravenous solutions in series, i.e., do not piggyback connections. Such use could result in air embolism due to residual air being drawn from one container before administration of the fluid from a secondary container is completed. Pressurizing intravenous solutions contained in flexible plastic containers to increase flow rates can result in air embolism if the residual air in the container is not fully evacuated prior to administration. Use of a vented intravenous administration set with the vent in the open position could result in air embolism. Vented intravenous administration sets with the vent in the open position should not be used with flexible plastic containers. Laboratory Tests Clinical evaluation and periodic laboratory determinations are necessary to monitor changes in fluid balance, electrolyte concentrations, and acid base balance during prolonged parenteral therapy or whenever the condition of the patient warrants such evaluation. Drug Interactions Caution must be exercised in the administration of 3% and 5% Sodium Chloride Injection, USP to patients receiving corticosteroids or corticotropin.

Each 100 mL contains 234 mg of Sodium Chloride, USP (NaCl); 128 mg of Potassium Acetate, USP (C2H3KO2); and 32 mg of Magnesium Acetate Tetrahydrate (Mg(C2H3O2)2•4H2O). It contains no antimicrobial agents. The pH is adjusted with hydrochloric acid. The pH is 5.5 (4.0 to 8.0). PLASMA-LYTE 56 Injection (Multiple Electrolytes Injection, Type 1, USP) administered intravenously has value as a source of water and electrolytes. One liter has an ionic concentration of 40 mEq sodium, 13 mEq potassium, 3 mEq magnesium, 40 mEq chloride, and 16 mEq acetate. The osmolarity is 111 mOsmol/L (calc). Normal physiologic osmolarity range is approximately 280 to 310 mOsmol/L. Administration of substantially hypertonic solutions may cause vein damage. The flexible container is made with non-latex plastic materials specially designed for a wide range of parenteral drugs including those requiring delivery in containers made of polyolefins or polypropylene. For example, the AVIVA container system is compatible with and appropriate for use in the admixture and administration of paclitaxel. In addition, the AVIVA container system is compatible with and appropriate for use in the admixture and administration of all drugs deemed compatible with existing polyvinyl chloride container systems. The solution contact materials do not contain PVC, DEHP, or other plasticizers. The suitability of the container materials has been established through biological evaluations, which have shown the container passes Class VI U.S. Pharmacopeia (USP) testing for plastic containers. These tests confirm the biological safety of the container system. The flexible container is a closed system, and air is prefilled in the container to facilitate drainage. The container does not require entry of external air during administration. The container has two ports: one is the administration outlet port for attachment of an intravenous administration set and the other port has a medication site for addition of supplemental medication (See Directions for Use). The primary function of the overwrap is to protect the container from the physical environment. Clinical Pharmacology This label may not be the latest approved by FDA.

It is capable of inducing diuresis depending on the clinical condition of the patient. PLASMA-LYTE 56 Injection (Multiple Electrolytes Injection, Type 1, USP) produces a metabolic alkalinizing effect. Acetate ions are metabolized ultimately to carbon dioxide and water, which requires the consumption of hydrogen cations. Indications and Usage PLASMA-LYTE 56 Injection (Multiple Electrolytes Injection, Type 1, USP) is indicated as a source of water and electrolytes or as an alkalinizing agent. Contraindications None known Warnings PLASMA-LYTE 56 Injection (Multiple Electrolytes Injection, Type 1, USP) should be used with great care, if at all, in patients with congestive heart failure, severe renal insufficiency and in clinical states in which there exists edema with sodium retention. PLASMA-LYTE 56 Injection (Multiple Electrolytes Injection, Type 1, USP) should be used with great care, if at all, in patients with hyperkalemia, severe renal failure and in conditions in which potassium retention is present. PLASMA-LYTE 56 Injection (Multiple Electrolytes Injection, Type 1, USP) should be used with great care in patients with metabolic or respiratory alkalosis. The administration of acetate ions should be done with great care in those conditions in which there is an increased level or an impaired utilization of these ions, such as severe hepatic insufficiency. PLASMA-LYTE 56 Injection (Multiple Electrolytes Injection, Type 1, USP) should not be administered simultaneously with blood through the same administration set because of the possibility of hemolysis. The intravenous administration of PLASMA-LYTE 56 Injection (Multiple Electrolytes Injection, Type 1, USP) can cause fluid and/or solute overloading resulting in dilution of serum electrolyte concentrations, overhydration, congested states or pulmonary edema. The risk of dilutional states is inversely proportional to the electrolyte concentrations of the injection. The risk of solute overload causing congested states with peripheral and pulmonary edema is directly proportional to the electrolyte concentrations of the injection. In patients with diminished renal function, administration of PLASMA-LYTE 56 Injection (Multiple Electrolytes Injection, Type 1, USP) may result in sodium or potassium retention.

Other reported clinical experience has not identified differences in responses between the elderly and younger patients. In general, dose selection for an elderly patient should be cautious, usually starting at the low end of the dosing range, reflecting the greater frequency of decreased hepatic, renal, or cardiac function, and of concomitant disease or drug therapy. This drug is known to be substantially excreted by the kidney, and the risk of toxic reactions to this drug may be greater in patients with impaired renal function. Because elderly patients are more likely to have decreased renal function, care should be taken in dose selection, and it may be useful to monitor renal function. Adverse Reactions Reactions which may occur because of the solution or the technique of administration include febrile response, infection at the site of injection, venous thrombosis or phlebitis extending from the site of injection, extravasation and hypervolemia. If an adverse reaction does occur, discontinue the infusion, evaluate the patient, institute appropriate therapeutic countermeasures and save the remainder of the fluid for examination if deemed necessary. Dosage and Administration As directed by a physician. Dosage is dependent upon the age, weight, and clinical condition of the patient as well as laboratory determinations. Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration whenever solution and container permit.

DIANEAL Peritoneal Dialysis Solution For intraperitoneal administration only DIANEAL PD-2 Peritoneal Dialysis Solution With 1.5% Dextrose DIANEAL PD-2 Peritoneal Dialysis Solution With 2.5% Dextrose DIANEAL PD-2 Peritoneal Dialysis Solution With 4.25% Dextrose DIANEAL Low Calcium (2.5 mEq/L) Peritoneal Dialysis Solution With 1.5% Dextrose DIANEAL Low Calcium (2.5 mEq/L) Peritoneal Dialysis Solution With 2.5% Dextrose DIANEAL Low Calcium (2.5 mEq/L) Peritoneal Dialysis Solution With 4.25% Dextrose DESCRIPTION DIANEAL Peritoneal Dialysis Solutions are sterile, nonpyrogenic solutions in flexible containers for intraperitoneal administration only. The peritoneal dialysis solutions contain no bacteriostatic or antimicrobial agents. Composition, calculated osmolarity, pH, and ionic concentrations are shown in Tables 1-6. DIANEAL is a hyperosmolar solution. The plastic container is fabricated from polyvinyl chloride (PL 146 Plastic). Exposure to temperatures above 25°C/77°F during transport and storage will lead to minor losses in moisture content. Higher temperatures lead to greater losses. It is unlikely that these minor losses will lead to clinically significant changes within the expiration period. The amount of water that can permeate from inside the solution container into the overwrap is insufficient to affect the solution significantly. Solutions in contact with the plastic container can leach out certain of its chemical components in very small amounts within the expiration period, e.g. di-2-ethylhexyl phthalate (DEHP), up to 5 parts per million; however, the safety of the plastic has been confirmed in tests in animals according to USP biological tests for plastic containers as well as by cell culture toxicity studies. CLINICAL PHARMACOLOGY Mechanism of Action DIANEAL is a hypertonic peritoneal dialysis solution containing dextrose, a monosaccharide, as the primary osmotic agent. An osmotic gradient must be created between the peritoneal membrane and the dialysis solution in order for ultrafiltration to occur. The hypertonic concentration of glucose in DIANEAL exerts an osmotic pressure across the peritoneal membrane resulting in transcapillary ultrafiltration. Like other peritoneal dialysis solutions, DIANEAL contains electrolytes to facilitate the correction of electrolyte abnormalities. DIANEAL contains a buffer, lactate, to help normalize acid- base abnormalities. Pharmacokinetics of DIANEAL Glucose content in DIANEAL is expressed as dextrose monohydrate and is available in three concentrations: 1.5%, 2.5% and 4.25%. Reference ID: 3814105 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda Glucose is rapidly absorbed from the peritoneal cavity by diffusion and appears quickly in the circulation due to the high glucose concentration gradient between DIANEAL compared to blood capillary glucose level. Absorption per unit time will be the highest at the start of an exchange and decreases over time. The rate of glucose absorption will be dependent upon the transport characteristics of the patient’s peritoneal membrane as determined by a peritoneal equilibration test (PET). Glucose absorption will also depend upon the concentration of glucose used for the exchange and the length of the dwell. Glucose is metabolized by normal cellular pathways (e.g. glycolysis) and provides a source of calories and may elevate blood glucose levels. Transport of other molecules across the peritoneal membrane, such as lactate, will occur by diffusion. Metabolism of lactate occurs in the liver and results in the generation of the bicarbonate. Transport of other molecules will be dependent upon the molecular size of the solute, the concentration gradient, and the effective peritoneal surface area as determined by the PET. INDICATIONS AND USAGE DIANEAL peritoneal dialysis solutions are indicated for patients in acute or chronic renal failure when nondialytic medical therapy is judged to be inadequate. CONTRAINDICATIONS DIANEAL is contraindicated in patients with pre-existing severe lactic acidosis. WARNINGS Encapsulating Peritoneal Sclerosis (EPS) is considered to be a known, rare complication of peritoneal dialysis therapy. EPS has been reported in patients using peritoneal dialysis solutions including DIANEAL. Infrequently, fatal outcomes of EPS have been reported with DIANEAL. Because Dianeal is a dextrose-based solution, patients with allergy to corn or corn products are at increased risk for allergic reaction, which may include anaphylactic/anaphylactoid reactions. Stop the infusion immediately, drain the solution from the peritoneal cavity and treat appropriately if any signs or symptoms of a suspected hypersensitivity reaction develop. Patients with severe lactic acidosis should not be treated with lactate-based peritoneal dialysis solutions (See Contraindications). Patients with conditions known to increase the risk of lactic acidosis [e.g., severe hypotension or sepsis that can be associated with acute renal failure, hepatic failure, inborn errors of metabolism, and treatment with drugs such as nucleoside/nucleotide reverse transcriptase inhibitors (NRTIs)] must be monitored for the occurrence of lactic acidosis before the start of treatment and during treatment with lactate-based peritoneal dialysis solutions. When prescribing the solution to be used for an individual patient, consideration should be given to the potential interaction between the dialysis treatment and therapy directed at other existing illnesses. Serum potassium levels should be monitored carefully in patients treated with cardiac glycosides. For example, rapid potassium removal may create arrhythmias in cardiac patients using digitalis or similar drugs; digitalis toxicity may be masked by hyperkalemia, hypermagnesemia, or hypocalcemia. Correction of electrolytes by dialysis may precipitate signs and symptoms of digitalis excess. Conversely, toxicity may occur at suboptimal dosages of digitalis if potassium is low or calcium is high. Diabetics require careful monitoring of insulin requirements and other treatments for hyperglycemia during and following dialysis with dextrose containing solutions. Reference ID: 3814105 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda PRECAUTIONS General Peritoneal-Dialysis Related DIANEAL is intended for intraperitoneal administration only. Not for intravenous administration. The following conditions may predispose to adverse reactions to peritoneal dialysis procedures: abdominal conditions, including uncorrectable mechanical defects that prevent effective peritoneal dialysis or increase the risk of infection, disruption of the peritoneal membrane and diaphragm by surgery, congenital anomalies or trauma prior to complete healing, abdominal tumors, abdominal wall infections, hernias, fecal fistula, colostomies or ileostomies, frequent episodes of diverticulitis, inflammatory or ischemic bowel disease, large polycystic kidneys, or other conditions that compromise the integrity of the abdominal wall, abdominal surface, or intra-abdominal cavity, such as documented loss of peritoneal function or extensive adhesions that compromise peritoneal function. Conditions that preclude normal nutrition, impaired respiratory function, recent aortic graft placement, and potassium deficiency may also predispose to complications of peritoneal dialysis. Aseptic technique must be employed throughout the peritoneal dialysis procedure to reduce the possibility of infection. Following use, the drained fluid should be inspected for the presence of fibrin or cloudiness, which may indicate the presence of peritonitis. If peritonitis occurs, the choice and dosage of antibiotics should be based upon the results of identification and sensitivity studies of the isolated organism(s) when possible. Prior to identification of the involved organism(s), broad-spectrum antibiotics may be indicated. Overinfusion of peritoneal dialysis solution volume into the peritoneal cavity may be characterized by abdominal distention, feeling of fullness and/or shortness of breath. Treatment of overinfusion is to drain the peritoneal dialysis solution from the peritoneal cavity. Need for Trained Physician Treatment should be initiated and monitored under the supervision of a physician knowledgeable in the management of patients with renal failure. A patient’s volume status should be carefully monitored to avoid hyper- or hypovolemia and potentially severe consequences including congestive heart failure, volume depletion and hypovolemic shock. An accurate fluid balance record must be kept and the patient’s body weight monitored. Excessive use of DIANEAL peritoneal dialysis solution with higher dextrose concentration during a peritoneal dialysis treatment may result in significant removal of water from the patient (see Dosage and Administration). Significant losses of protein, amino acids, water-soluble vitamins and other medicines may occur during peritoneal dialysis. The patient’s nutritional status should be monitored and replacement therapy should be provided as necessary. Information for Patients Patients should be instructed not to use solutions if they are cloudy, discolored, contain visible particulate matter, or if they show evidence of leaking containers (see Dosage and Administration). Aseptic technique must be employed throughout the procedure. An improper clamping sequence may result in infusion of air into the peritoneum (see Dosage and Administration, Directions for Use). Reference ID: 3814105 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda To reduce possible discomfort during administration, patients should be instructed that solutions may be warmed to 37°C (98°F) prior to use. Only dry heat should be used. It is best to warm solutions within the overwrap using a heating pad. To avoid contamination, solutions should not be immersed in water for warming. Do not use a microwave oven to warm the solution (see Dosage and Administration, Directions for Use). Laboratory Tests Serum Electrolytes DIANEAL does not contain potassium. Evaluate serum potassium prior to administering potassium chloride to the patient. In situations where there is a normal serum potassium level or hypokalemia, addition of potassium chloride (up to a concentration of 4 mEq/L) to the solution may be necessary to prevent severe hypokalemia. This should be made under careful evaluation of serum and total body potassium, and only under the direction of a physician. Fluid, hematology, blood chemistry, electrolyte concentrations, and bicarbonate should be monitored periodically. If serum magnesium levels are low, magnesium supplements may be used. Patients receiving DIANEAL solutions should have their calcium levels monitored for the development of hypocalcemia or hypercalcemia. In these circumstances, adjustments to the dosage of the phosphate binders, vitamin D analogs, and/or calcimimetics should be considered by the physician. DIANEAL Low Calcium (2.5 mEq/L) Peritoneal Dialysis solution should be considered for use in patients with hypercalcemia. Carcinogenesis, Mutagenesis, Impairment of Fertility Studies to evaluate the carcinogenic or mutagenic potential of this product, or its potential to affect fertility adversely, have not been performed. Drug Interactions No clinical drug interaction studies were performed. As with other dialysis solutions, blood concentrations of dialyzable drugs may be reduced by dialysis. Dosage adjustment of concomitant medications may be necessary. In patients using cardiac glycosides (digoxin and others), plasma levels of calcium, potassium and magnesium must be carefully monitored (see Warnings). Use in Specific Population Pregnancy Pregnancy Category C. DIANEAL is a peritoneal dialysis solution of electrolytes, lactate and dextrose and is pharmacologically inactive. Animal reproduction studies have not been conducted with DIANEAL dialysis solution. While there are no adequate and well controlled studies in pregnant women, appropriate administration of DIANEAL with monitoring of fluid, electrolyte, acid-base and glucose balance, is not expected to cause fetal harm, or affect reproductive capacity. Maintenance of normal acid-base balance is important for fetal well being. Physicians should carefully consider the potential risks and benefits for each specific patient before prescribing DIANEAL. Nursing Mothers DIANEAL is a dialysis solution of electrolytes, lactate and dextrose and is pharmacologically inactive. The components of DIANEAL are excreted in human milk. Appropriate administration of DIANEAL with monitoring of fluid, electrolyte, acid-base and glucose balance, is not expected to harm a nursing infant. Physicians should carefully consider the potential risks and benefits for each specific patient before prescribing DIANEAL. Pediatric Use Safety and effectiveness have been established based on published clinical data. No adequate and well-controlled studies have been conducted with DIANEAL solutions in pediatric patients. Reference ID: 3814105 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda Geriatric Use Safety and effectiveness have been established based on published clinical data. ADVERSE REACTIONS The following adverse reactions have been identified during post approval use of DIANEAL. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship during drug exposure. Adverse reactions are listed by MedDRA System Organ Class (SOC), then by Preferred Term in order of severity. INFECTIONS AND INFESTATIONS: Fungal peritonitis, Peritonitis bacterial, Catheter related infection METABOLISM AND NUTRITION DISORDERS: Hypovolemia, Hypervolemia, Fluid retention, Hypokalemia, Hyponatremia, Dehydration, Hypochloremia VASCULAR DISORDERS: Hypotension, Hypertension RESPIRATORY, THORACIC, AND MEDIASTINAL DISORDERS: Dyspnea GASTROINTESTINAL DISORDERS: Sclerosing encapsulating peritonitis, Peritonitis, Peritoneal cloudy effluent, Vomiting, Diarrhea, Nausea, Constipation, Abdominal pain, Abdominal distension, Abdominal discomfort SKIN AND SUBCUTANEOUS DISORDERS: Stevens-Johnson syndrome, Urticaria, Rash, (including pruritic, erythematous and generalized), Pruritus MUSCULOSKELETAL, CONNECTIVE TISSUE DISORDERS: Myalgia, Muscle spasms, Musculoskeletal pain GENERAL DISORDERS AND ADMINISTRATION SITE CONDITIONS: Generalized edema, Pyrexia, Malaise, Infusion site pain, Catheter related complication DRUG ABUSE AND DEPENDENCE There has been no observed potential of drug abuse or dependence with DIANEAL solution. OVERDOSAGE There is a potential for overdose resulting in hypervolemia, hypovolemia, electrolyte disturbances or hyperglycemia. Excessive use of DIANEAL peritoneal dialysis solution with 4.25% dextrose during a peritoneal dialysis treatment can result in significant removal of water from the patient. DOSAGE AND ADMINISTRATION DIANEAL peritoneal dialysis solutions are intended for intraperitoneal administration only. The mode of therapy, frequency of treatment, formulation, exchange volume, duration of dwell, and length of dialysis should be selected by the physician responsible for and supervising the treatment of the individual patient. DIANEAL should be administered at a rate that is comfortable for the patient, generally over a period of 10-20 minutes for a single exchange. Patients on continuous ambulatory peritoneal dialysis (CAPD) typically perform 4 cycles per day (24 hours). Patients on automated peritoneal dialysis (APD) typically perform 4-5 cycles at night and up Reference ID: 3814105 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda to 2 cycles during the day. The fill volume depends on body size, usually from 2.0 to 2.5 liters per 1.73m2 . To avoid the risk of severe dehydration and hypovolemia and to minimize the loss of protein, it is advisable to select the peritoneal dialysis solution with the lowest level of osmolarity consistent with the fluid removal requirements for that exchange. As the patient’s body weight becomes closer to the ideal dry weight, lowering the dextrose concentration of DIANEAL is recommended. DIANEAL 4.25% dextrose-containing solution has the highest osmolarity of the DIANEAL solutions and using it for all exchanges may cause dehydration. Solutions that are cloudy, discolored, contain visible particulate matter, or show evidence of leakage should not be used. Following use, the drained fluid should be inspected for the presence of fibrin or cloudiness which may indicate the presence of peritonitis. For single use only. Discard unused portion. It is recommended that patients being placed on peritoneal dialysis and/or their caretaker(s) should be appropriately trained. Addition of Potassium Potassium is omitted from DIANEAL solutions because dialysis may be performed to correct hyperkalemia. In situations where there is a normal serum potassium level or hypokalemia, the addition of potassium chloride (up to a concentration of 4 mEq/L) may be indicated to prevent severe hypokalemia. The decision to add potassium chloride should be made by the physician after careful evaluation of serum potassium. Addition of Insulin Patients with insulin-dependent diabetes may require modification of insulin dosage following initiation of treatment with DIANEAL. Appropriate monitoring of blood glucose should be performed when initiating DIANEAL in diabetic patients and insulin dosage adjusted if needed (see Warnings). Addition of Heparin No human drug interaction studies with heparin were conducted. In vitro studies demonstrated no evidence of incompatibility of heparin with DIANEAL. Addition of Antibiotics No formal clinical drug interaction studies have been performed. In vitro studies of the following medications have demonstrated stability with DIANEAL: amphotericin B, ampicillin, cefazolin, cefepime, cefotaxime, ceftazidime, ceftriaxone, ciprofloxacin, clindamycin, deferoxamine, erythromycin, gentamicin, linezolid, mezlocillin, miconazole, moxifloxacin, nafcillin, ofloxacin, penicillin G, piperacillin, sulfamethoxazole/trimethoprim, ticarcillin, tobramycin, and vancomycin. However, aminoglycosides should not be mixed with penicillins due to chemical incompatibility. Directions for Use For complete CAPD and APD system preparation, see directions accompanying ancillary equipment. Aseptic technique must be used throughout the peritoneal dialysis procedure. Warming For patient comfort, DIANEAL can be warmed to 37°C (98°F). Only dry heat should be used. It is best to warm solutions within the overwrap using a heating pad. Do not immerse DIANEAL in water for warming. Do not use a microwave oven to warm DIANEAL. Reference ID: 3814105 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda To Open To open, tear the overwrap down at the slit and remove the solution container. Some opacity of the plastic, due to moisture absorption during the sterilization process, may be observed. This does not affect the solution quality or safety and may often leave a slight amount of moisture within the overwrap. The opacity should diminish gradually. Inspect for Container Integrity Inspect the bag connector to ensure the tip protector (pull ring, blue pull tip, or blue twist-off tip) is attached. Do not use if the tip protector is not attached to the connector. Inspect the DIANEAL container for signs of leakage and check for minute leaks by squeezing the container firmly. If the container has frangible(s), inspect that they are positioned correctly and are not broken. Do not use DIANEAL if the frangible(s) are broken or leaks are suspected as sterility may be impaired. For DIANEAL in ULTRABAG, inspect the tubing and drain container for presence of solution. Small droplets are acceptable, but if solution flows past the frangible prior to use, do not use and discard the units. Adding Medications Some drug additives may be incompatible with DIANEAL. See DOSAGE AND ADMINISTRATION section for additional information.

Dextrose Injection, USP in AVIVA Plastic Container DESCRIPTION Dextrose Injection, USP is a sterile, nonpyrogenic solution for fluid replenishment and caloric supply in single dose containers for intravenous administration. It contains no antimicrobial agents. Composition, osmolarity, pH, and caloric content are shown in Table 1. Table 1 Size (mL) *Dextrose Hydrous, USP (g/L) Osmolarity (mOsmol/L) (calc.) pH nominal (range) Caloric Content (kcal/L) 5% Dextrose Injection, USP 250 500 1000 50 252 4.5 (3.2 to 6.5) 170 10% Dextrose Injection, USP 250 500 1000 100 505 4.5 (3.2 to 6.5) 340 The flexible container is made with non-latex plastic materials specially designed for a wide range of parenteral drugs including those requiring delivery in containers made of polyolefins or polypropylene. For example, the AVIVA container system is compatible with and appropriate for use in the admixture and administration of paclitaxel. In addition, the AVIVA container system is compatible with and appropriate for use in the admixture and administration of all drugs deemed compatible with existing polyvinyl chloride container systems. The solution contact materials do not contain PVC, DEHP, or other plasticizers. Reference ID: 3677008 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda The suitability of the container materials has been established through biological evaluations, which have shown the container passes Class VI U.S. Pharmacopeia (USP) testing for plastic containers. These tests confirm the biological safety of the container system. The flexible container is a closed system, and air is prefilled in the container to facilitate drainage. The container does not require entry of external air during administration. The container has two ports: one is the administration outlet port for attachment of an intravenous administration set and the other port has a medication site for addition of supplemental medication (see DIRECTIONS FOR USE). The primary function of the overwrap is to protect the container from the physical environment. CLINICAL PHARMACOLOGY Dextrose Injection, USP has value as a source of water and calories. It is capable of inducing diuresis depending on the clinical condition of the patient. INDICATIONS AND USAGE Dextrose Injection, USP is indicated as a source of water and calories. CONTRAINDICATIONS Solutions containing dextrose may be contraindicated in patients with known allergy to corn or corn products. WARNINGS Dextrose Injection, USP should not be administered simultaneously with blood through the same administration set because of the possibility of pseudoagglutination or hemolysis. The intravenous administration of these solutions can cause fluid and/or solute overloading resulting in dilution of serum electrolyte concentrations, overhydration, congested states, or pulmonary edema. The risk of dilutive states is inversely proportional to the electrolyte concentrations of the injections. The risk of solute overload causing congested states with peripheral and pulmonary edema is directly proportional to the electrolyte concentrations of the injections. Excessive administration of dextrose injections may result in significant hypokalemia. Reference ID: 3677008 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda In very low birth weight infants, excessive or rapid administration of dextrose injection may result in increased serum osmolality and possible intracerebral hemorrhage. Clinical evaluation and periodic laboratory determinations are necessary to monitor changes in fluid balance, electrolyte concentrations, and acid base balance during prolonged parenteral therapy or whenever the condition of the patient warrants such evaluation. PRECAUTIONS General Do not connect flexible plastic containers in series in order to avoid air embolism due to possible residual air contained in the primary container. Such use could result in air embolism due to residual air being drawn from the primary container before administration of the fluid from a secondary container is completed. Pressurizing intravenous solutions contained in flexible plastic containers to increase flow rates can result in air embolism if the residual air in the container is not fully evacuated prior to administration. Use of a vented intravenous administration set with the vent in the open position could result in air embolism. Vented intravenous administration sets with the vent in the open position should not be used with flexible plastic containers. Dextrose Injection, USP should be used with caution in patients with overt or subclinical diabetes mellitus. Pregnancy Pregnancy Category C There are no adequate and well controlled studies with Dextrose Injection, USP in pregnant women and animal reproduction studies have not been conducted with this drug. Therefore, it is not known whether Dextrose Injection, USP can cause fetal harm when administered to a pregnant woman. Dextrose Injection, USP should be given during pregnancy only if the potential benefit justifies the potential risk to the fetus. Reference ID: 3677008 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda Labor and Delivery Intrapartum maternal intravenous infusion of glucose-containing solutions may produce maternal hyperglycemia with subsequent fetal hyperglycemia and fetal metabolic acidosis. Fetal hyperglycemia can result in increased fetal insulin levels which may result in neonatal hypoglycemia following delivery. Consider the potential risks and benefits for each specific patient before administering Dextrose Injection, USP. Nursing Mothers It is not known whether this drug is present in human milk. Because many drugs are present in human milk, caution should be exercised when Dextrose Injection, USP is administered to a nursing woman. Pediatric Use The use of Dextrose Injection, USP in pediatric patients is based on clinical practice (see DOSAGE AND ADMINISTRATION). Newborns – especially those born premature and with low birth weight - are at increased risk of developing hypo- or hyperglycemia and therefore need close monitoring during treatment with intravenous glucose solutions to ensure adequate glycemic control in order to avoid potential long term adverse effects. Hypoglycemia in the newborn can cause prolonged seizures, coma and brain damage. Hyperglycemia has been associated with intraventricular hemorrhage, late onset bacterial and fungal infection, retinopathy of prematurity, necrotizing enterocolitis, bronchopulmonary dysplasia, prolonged length of hospital stay, and death. Geriatric Use Clinical studies of Dextrose Injection, USP did not include sufficient numbers of subjects aged 65 and over to determine whether they respond differently from younger subjects. Other reported clinical experience has not identified differences in responses between the elderly and younger patients. In general, dose selection for an elderly patient should be cautious, usually starting at the low end of the dosing range, reflecting the greater frequency of decreased hepatic, renal, or cardiac function, and of concomitant disease or other drug therapy. This drug is known to be substantially excreted by the kidney, and the risk of toxic reactions to this drug may be greater in patients with impaired renal function. Because Reference ID: 3677008 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda elderly patients are more likely to have decreased renal function, care should be taken in dose selection, and it may be useful to monitor renal function. ADVERSE REACTIONS Hypersensitivity reactions, including anaphylaxis and chills. Reactions which may occur because of the injection or the technique of administration include febrile response, infection at the site of injection, venous thrombosis or phlebitis extending from the site of injection, extravasation and hypervolemia. If an adverse reaction does occur, discontinue the infusion, evaluate the patient, institute appropriate therapeutic countermeasures and save the remainder of the fluid for examination if deemed necessary. DOSAGE AND ADMINISTRATION As directed by a physician. Dosage is dependent upon the age, weight and clinical condition of the patient as well as laboratory determinations. Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration whenever solution and container permit. Use of a final filter is recommended during administration of all parenteral solutions, where possible. Do not administer unless solution is clear and seal is intact. All injections in AVIVA plastic containers are intended for intravenous administration using sterile equipment. The dosage selection and constant infusion rate of intravenous dextrose must be selected with caution in pediatric patients, particularly neonates and low birth weight infants, because of the increased risk of hyperglycemia/ hypoglycemia. Frequent monitoring of serum glucose concentrations is required when dextrose is prescribed to pediatric patients, particularly neonates and low birth weight infants. The infusion rate and volume depends on the age, weight, clinical and metabolic conditions of the patient, concomitant therapy and should be determined by the consulting physician experienced in pediatric intravenous fluid therapy. Additives may be incompatible. Complete information is not available. Those additives known to be incompatible should not be used. Consult with pharmacist, if available. If, in Reference ID: 3677008 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda the informed judgment of the physician, it is deemed advisable to introduce additives, use aseptic technique.

For current labeling information, please visit https://www.fda.gov/drugsatfda 70% Dextrose Injection, USP in VIAFLEX Plastic Container A Parenteral Nutrient DESCRIPTION Dextrose Injection, USP is a sterile, nonpyrogenic, hypertonic solution for fluid replenishment and caloric supply in single dose container for intravenous administration after compounding. It contains no antimicrobial agents. Composition, osmolarity, pH, and caloric content are shown in Table 1. Table 1 Composition Osmolarity (mOsmol/L) (calc.) pH Caloric Content (kcal/L) How Supplied Dextrose Hydrous, USP (g/L) Size 500 mL in 1000 mL container Code and NDC 70% Dextrose Injection, USP 700 3530 4.0 (3.2 to 6.5) 2390 2B0114 NDC 0338-0719-13 The structural formula of Dextrose Hydrous, USP is: The VIAFLEX plastic container is fabricated from a specially formulated polyvinyl chloride (PL 146 Plastic). Exposure to temperatures above 25ºC/77ºF during transport and storage will lead to minor losses in moisture content. Higher temperatures lead to greater losses. It is unlikely that these minor losses will lead to clinically significant Reference ID: 3677008 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda changes within the expiration period. The amount of water that can permeate from inside the container into the overwrap is insufficient to affect the solution significantly. Solutions in contact with the plastic container may leach out certain chemical components from the plastic in very small amounts; however, biological testing was supportive of the safety of the plastic container materials. CLINICAL PHARMACOLOGY Dextrose Injection, USP have value as a source of water and calories. They are capable of inducing diuresis depending on the clinical condition of the patient. INDICATIONS AND USAGE Dextrose Injection, USP are indicated as a caloric component in a parenteral nutrition regimen. They are used with an appropriate protein (nitrogen) source in the prevention of nitrogen loss or in the treatment of negative nitrogen balance in patients where: (1) the alimentary tract cannot or should not be used, (2) gastrointestinal absorption of protein is impaired, or (3) metabolic requirements for protein are substantially increased, as with extensive burns. CONTRAINDICATIONS The infusion of hypertonic dextrose injection is contraindicated in patients having intracranial or intraspinal hemorrhage, in patients who are severely dehydrated, in patients who are anuric, and in patients in hepatic coma. Solutions containing dextrose may be contraindicated in patients with known allergy to corn or corn products. WARNINGS Dilute before use to a concentration which will, when administered with an amino acid (nitrogen) source, result in an appropriate calorie to gram of nitrogen ratio and which has an osmolarity consistent with the route of administration. Unless appropriately diluted, the infusion of hypertonic dextrose injection into a peripheral vein may result in vein irritation, vein damage, and thrombosis. Strongly hypertonic nutrient solutions should only be administered through an indwelling intravenous catheter with the tip located in a large central vein such as the superior vena cava. Reference ID: 3677008 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda In very low birth weight infants, excessive or rapid administration of dextrose injection may result in increased serum osmolality and possible intracerebral hemorrhage. WARNING: This product contains aluminum that may be toxic. Aluminum may reach toxic levels with prolonged parenteral administration if kidney function is impaired. Premature neonates are particularly at risk because their kidneys are immature, and they require large amounts of calcium and phosphate solutions, which contain aluminum. Research indicates that patients with impaired kidney function, including premature neonates, who receive parenteral levels of aluminum at greater than 4 to 5 mcg/kg/day accumulate aluminum at levels associated with central nervous system and bone toxicity. Tissue loading may occur at even lower rates of administration. Monitor changes in fluid balance, electrolyte concentrations, and acid base balance during prolonged parenteral therapy or whenever the condition of the patient warrants such evaluation. PRECAUTIONS General Do not connect flexible plastic containers in series in order to avoid air embolism due to possible residual air contained in the primary container. Such use could result in air embolism due to residual air being drawn from the primary container before administration of the fluid from the secondary container is completed. Pressurizing intravenous solutions contained in flexible plastic containers to increase flow rates can result in air embolism if the residual air in the container is not fully evacuated prior to administration. Use of a vented intravenous administration set with the vent in the open position could result in air embolism. Vented intravenous administration sets with the vent in the open position should not be used with flexible plastic containers. Administration of hypertonic dextrose and amino acid solutions via central venous catheter may be associated with complications which can be prevented or minimized by careful attention to all aspects of the procedure. This includes attention to solution preparation, administration and patient monitoring. Reference ID: 3677008 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda It is essential that a carefully prepared protocol, based upon current medical practice, be followed, preferably by an experienced medical team. The package insert of the protein (nitrogen) source should be consulted for dosage and all precautionary information. Care should be taken to avoid circulatory overload, particularly in patients with cardiac insufficiency. Caution must be exercised in the administration of these injections to patients receiving corticosteroids or corticotropin. These injections should be used with caution in patients with overt or subclinical diabetes mellitus. Drug product contains no more than 25 mcg/L of aluminum. Pregnancy Pregnancy Category C There are no adequate and well controlled studies with Dextrose Injections, USP in pregnant women and animal reproduction studies have not been conducted with this drug. Therefore, it is not known whether Dextrose Injections, USP can cause fetal harm when administered to a pregnant woman. Dextrose Injections, USP should be given during pregnancy only if the potential benefit justifies the potential risk to the fetus. Labor and Delivery Intrapartum maternal intravenous infusion of glucose-containing solutions may produce maternal hyperglycemia with subsequent fetal hyperglycemia and fetal metabolic acidosis. Fetal hyperglycemia can result in increased fetal insulin levels which may result in neonatal hypoglycemia following delivery. Consider the potential risks and benefits for each specific patient before administering Dextrose Injection, USP. Nursing Mothers It is not known if this drug is present in human milk. Because many drugs are present in human milk, caution should be exercised when Dextrose Injection, USP, is administered to a nursing woman.

RETIN-A® Cream Gel Liquid (tretinoin) For Topical Use Only Prescribing Information Description: RETIN-A Gel, Cream, and Liquid, containing tretinoin are used for the topical treatment of acne vulgaris. RETIN-A Gel contains tretinoin (retinoic acid, vitamin A acid) in either of two strengths, 0.025% or 0.01% by weight, in a gel vehicle of butyl alcohol, hydroxypropyl cellulose and alcohol (denatured with tert- butylated hydroxytoluene, and brucine sulfate) 90% w/w. RETIN-A (tretinoin) Cream contains tretinoin in either of three strengths, 0.1%, 0.05%, or 0.025% by weight, in a hydrophilic cream vehicle of stearic acid, isopropyl myristate, polyoxyl 40 stearate, stearyl alcohol, xanthan gum, sorbic acid, butylated hydroxytoluene, and purified water. RETIN-A Liquid contains tretinoin 0.05% by weight, polyethylene glycol 400, butylated hydroxytoluene and alcohol (denatured with tert-butyl alcohol and brucine sulfate) 55%. Chemically, tretinoin is all-trans-retinoic acid and has the following structure: Leave space for structure. Clinical Pharmacology: Although the exact mode of action of tretinoin is unknown, current evidence suggests that topical tretinoin decreases cohesiveness of follicular epithelial cells with decreased microcomedo formation. Additionally, tretinoin stimulates mitotic activity and increased turnover of follicular epithelial cells causing extrusion of the comedones. Indications and Usage: RETIN-A is indicated for topical application in the treatment of acne vulgaris. The safety and efficacy of the long-term use of this product in the treatment of other disorders have not been established. Contraindications: Use of the product should be discontinued if hypersensitivity to any of the ingredients is noted. Warnings: GELS ARE FLAMMABLE. AVOID FIRE, FLAME OR SMOKING DURING USE. Keep out of reach of children. Keep tube tightly closed. Do not expose to heat or store at temperatures above 120°F (49°C). This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda Precautions: General: If a reaction suggesting sensitivity or chemical irritation occurs, use of the medication should be discontinued. Exposure to sunlight, including sunlamps, should be minimized during the use of RETIN- A, and patients with sunburn should be advised not to use the product until fully recovered because of heightened susceptibility to sunlight as a result of the use of tretinoin. Patients who may be required to have considerable sun exposure due to occupation and those with inherent sensitivity to the sun should exercise particular caution. Use of sunscreen products and protective clothing over treated areas is recommended when exposure cannot be avoided. Weather extremes, such as wind or cold, also may be irritating to patients under treatment with tretinoin. RETIN-A (tretinoin) acne treatment should be kept away from the eyes, the mouth, angles of the nose, and mucous membranes. Topical use may induce severe local erythema and peeling at the site of application. If the degree of local irritation warrants, patients should be directed to use the medication less frequently, discontinue use temporarily, or discontinue use altogether. Tretinoin has been reported to cause severe irritation on eczematous skin and should be used with utmost caution in patients with this condition. Drug Interactions: Concomitant topical medication, medicated or abrasive soaps and cleansers, soaps and cosmetics that have a strong drying effect, and products with high concentrations of alcohol, astringents, spices or lime should be used with caution because of possible interaction with tretinoin. Particular caution should be exercised in using preparations containing sulfur, resorcinol, or salicylic acid with RETIN-A. It also is advisable to “rest” a patient’s skin until the effects of such preparations subside before use of RETIN-A is begun. Carcinogenesis, Mutagenesis, Impairment to Fertility: In a 91-week dermal study in which CD-1 mice were administered 0.017% and 0.035% formulations of tretinoin, cutaneous squamous cell carcinomas and papillomas in the treatment area were observed in some female mice. A dose-related incidence of liver tumors in male mice was observed at those same doses. The maximum systemic doses associated with the administered 0.017% and 0.035% formulations are 0.5 and 1.0 mg/kg/day, respectively. These doses are two and four times the maximum human systemic dose, when adjusted for total body surface area. The biological significance of these findings is not clear because they occurred at doses that exceeded the dermal maximally tolerated dose (MTD) of tretinoin and because they were within the background natural occurrence rate for these tumors in this strain of mice. There was no evidence of carcinogenic potential when 0.025 mg/kg/day of tretinoin was administered topically to mice (0.1 times the maximum human systemic dose, adjusted for total body surface area). For purposes of comparisons of the animal exposure to systemic human exposure, the maximum human systemic dose is defined as 1 gram of 0.1% RETIN-A applied daily to a 50 kg person (0.02 mg tretinoin/kg body weight). This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda Studies in hairless albino mice suggest that concurrent exposure to tretinoin may enhance the tumorigenic potential of carcinogenic doses of UVB and UVA light form a solar simulator. This effect has been confirmed in a later study in pigmented mice, and dark pigmentation did not overcome the enhancement of photocarcinogenesis by 0.05% tretinoin. Although the significance of these studies to humans is not clear, patients should minimize exposure to sunlight or artificial ultraviolet irradiation sources. The mutagenic potential of tretinoin was evaluated in the Ames assay and in the in vivo mouse micronucleus assay, both of which were negative. In dermal Segment I fertility studies of another tretinoin formulation in rats, slight (not statistically significant) decreases in sperm count and motility were seen at 0.5 mg/kg/day (4 times the maximum human systemic dose adjusted for total body surface area), and slight (not statistically significant) increases in the number and percent of nonviable embryos in females treated with 0.25 mg/kg/day (2 times the maximum human systemic dose adjusted for total body surface area) and above were observed. A dermal Segment III study with RETIN-A has not been performed in any species. In oral Segment I and Segment III studies in rats with tretinoin, decreased survival of neonates and growth retardation were observed at doses in excess of 2 mg/kg/day (16 times the human topical does adjusted for total body surface area). Pregnancy: Teratogenic effects. Pregnancy Category C. Oral tretinoin has been shown to be teratogenic in rats, mice, hamsters, and subhuman primates. It was teratogenic and fetotoxic in Wistar rats when given orally or topically in doses greater than 1 mg/kg/day (8 times the maximum human systemic dose adjusted for total body surface area). However, variations in teratogenic doses among various strains of rats have been reported. In the cynomolgus monkey, which metabolically is closer to humans for tretinoin than the other species examined, fetal malformations were reported at doses of 10 mg/kg/day or greater, but none were observed at 5 mg/kg/day (83 times the maximum human systemic does adjusted for total body surface area), although increased skeletal variations were observed at all doses. A dose-related increase in embryolethality and abortion was reported. Similar results have also been reported in pigtail macaques. Topical tretinoin in animal teratogenicity tests has generated equivocal results. There is evidence for teratogenicity (shortened or kinked tail) of topical tretinoin in Wistar rats at doses greater than 1 mg/kg/day (8 times the maximum human systemic dose adjusted for total body surface area). Anomalies (humerus: short 13%, bent 6%, os parietal incompletely ossified 14%) have also been reported when 10 mg/kg/day was topically applied. This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda There are other reports in New Zealand White rabbits administered doses of greater than 0.2 mg/kg/day (3.3 times the maximum human systemic dose adjusted for total body surface area) of an increased incidence of domed head and hydrocephaly, typical of retinoid-induced fetal malformations in this species. In contrast, several well-controlled animals studies have shown that dermally applied tretinoin may be fetoxic, but not overly teratogenic in rats and rabbits at doses of 1.0 and 0.5 mg/kg/day, respectively (8 times the maximum human systemic does adjusted for total body surface area in both species). With widespread use of any drug, a small number of birth defect reports associated temporally with the administration of the drug would be expected by chance alone. Thirty human cases of temporally associated congenital malformations have been reported during two decades of clinical use of RETIN-A. Although no definite pattern of teratogenicity and no causal association has been established from these cases, five of the reports describe the rare birth defect category holoprosencephaly (defects associated with incomplete midline development of the forebrain). The significance of these spontaneous reports in terms of risk to the fetus is not known. Nonteratogenic effects: Topical tretinoin has been shown to be fetotoxic in rabbits when administered 0.5 mg/kg/day (8 times the maximum human systemic dose adjusted for total body surface area). Oral tretinoin has been shown to be fetotoxic, resulting in skeletal variations and increased intrauterine death in rats when administered 2.5 mg/kg/day (20 times the maximum human systemic dose adjusted for total body surface area). There are, however, no adequate and well-controlled studies in pregnant women. Tretinoin should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus. Nursing Mothers: It is not known whether this drug is excreted in human milk. Because many drugs are excreted in human milk, caution should be exercised when RETIN-A is administered to a nursing woman. Pediatric Use: Safety and effectiveness in pediatric patients below the age of 12 have not been established. Geriatric Use: Safety and effectiveness in a geriatric population have not been established. Clinical studies of RETIN-A did not include sufficient numbers of subjects aged 65 and over to determine whether they respond differently from younger patients. This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda Adverse Reactions: The skin of certain sensitive individuals may become excessively red, edematous, blistered, or crusted. If these effects occur, the medication should either be discontinued until the integrity of the skin is restored, or the medication should be adjusted to a level the patient can tolerate. True contact allergy to topical tretinoin is rarely encountered. Temporary hyper- or hypopigmentation has been reported with repeated application of RETIN-A. Some individuals have been reported to have heightened susceptibility to sunlight while under treatment with RETIN-A. To date, all adverse effects of RETIN-A have been reversible upon discontinuance of therapy (see Dosage and Administration Section). Overdosage: If medication is applied excessively, no more rapid or better results will be obtained and marked redness, peeling, or discomfort may occur. Oral ingestion of the drug may lead to the same side effects as those associated with excessive oral intake of Vitamin A. Dosage and Administration: RETIN-A Gel, Cream or Liquid should be applied once a day, before retiring, to the skin where acne lesions appear, using enough to cover the entire affected area lightly. Liquid: the liquid may be applied using a fingertip, gauze pad, or cotton swab. If gauze or cotton is employed, care should be taken not to oversaturate it, to the extent that the liquid would run into areas where treatment is not intended. Gel: Excessive application results in “pilling” of the gel, which minimizes the likelihood of over application by the patient. Application may cause a transitory feeling of warmth or slight stinging. In cases where it has been necessary to temporarily discontinue therapy or to reduce the frequency of application, therapy may be resumed or frequency of application increased when the patients become able to tolerate the treatment. Alteration of vehicle, drug concentration, or dose frequency should be closely monitored by careful observation of the clinical therapeutic response and skin tolerance. During the early weeks of therapy, an apparent exacerbation of inflammatory lesions may occur. This is due to the action of the medication on deep, previously unseen lesions and should not be considered a reason to discontinue therapy. Therapeutic results should be noticed after two to three weeks but more than six weeks of therapy may be required before definite beneficial effects are seen. This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda Once the acne lesions have responded satisfactorily, it may be possible to maintain the improvement with less frequent applications, or other dosage forms. Patients treated with RETIN-A (tretinoin) acne treatment may use cosmetics, but the area to be treated should be cleansed thoroughly before the medication is applied.

THIS PRODUCT IS TO BE USED ONLY ACCORDING TO YOUR DOCTOR’S INSTRUCTIONS, AND IT SHOULD NOT BE APPLIED TO OTHER AREAS OF THE BODY OR TO OTHER GROWTHS OR LESIONS. THE LONG-TERM SAFETY AND EFFECTIVENESS OF THIS PRODUCT IN OTHER DISORDERS HAVE NOT BEEN EVALUATED. IF YOU HAVE ANY QUESTIONS, BE SURE TO ASK YOUR DOCTOR. WARNINGS RETIN- A GELS ARE FLAMMABLE. AVOID FIRE, FLAME OR SMOKING DURING USE. Keep out of reach of children. Keep tube tightly closed. Do not expose to heat or store at temperatures above 120°F (49°C). PRECAUTIONS The effects of the sun on your skin. As you know, overexposure to natural sunlight or the artificial sunlight of a sunlamp can cause sunburn. Overexposure to the sun over many years may cause premature aging of the skin and even skin cancer. The chance of these effects occurring will vary depending on skin type, the climate and the care taken to avoid overexposure to the sun. Therapy with RETIN-A may make your skin more susceptible to sunburn and other adverse effects of the sun, so unprotected exposure to natural or artificial sunlight should be minimized. Laboratory findings. When laboratory mice are exposed to artificial sunlight, they often develop skin tumors. These sunlight-induced tumors may appear more quickly and in greater number if the mouse is also topically treated with the active ingredient in RETIN-A, tretinoin. In some studies, under different conditions, however, when mice treated with tretinoin were exposed to artificial sunlight, the incidence and rate of development of skin tumors was reduced. There is no evidence to date that tretinoin alone will cause the development of skin tumors in either laboratory animals or humans. However, investigations in this area are continuing. Use caution in the sun. When outside, even on hazy days, areas treated with RETIN-A should be protected. An effective sunscreen should be used any time you are outside (consult your physician for a recommendation of an SPF level which will provide you with the necessary high level of protection). For extended sun exposure, protective clothing, like a hat, should be worn. Do not use artificial sunlamps while you are using RETIN-A. If you do become sunburned, stop your therapy with RETIN-A until your skin has recovered. This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda Avoid excessive exposure to wind or cold. Extremes of climate tend to dry or burn normal skin. Skin treated with RETIN-A may be more vulnerable to these extremes. Your physician can recommend ways to manage your acne treatment under such conditions. Possible problems. The skin of certain sensitive individuals may become excessively red, swollen, blistered or crusted. If you are experiencing severe or persistent irritation, discontinues the use of RETIN-A and consult your physician. There have been reports that, in some patients, areas treated with RETIN-A developed a temporary increase or decrease in the amount of skin pigment (color) present. The pigment in these areas returned to normal either when the skin was allowed to adjust to RETIN-A or therapy was discontinued. Use other medication only on your physician’s advice. Only your physician knows which other medications may be helpful during treatment and will recommend them to you if necessary. Follow the physician’s instructions carefully. In addition, you should avoid preparations that may dry or irritate your skin. These preparations may include certain astringents, toiletries containing alcohol, spices or lime, or certain medicated soaps, shampoos and hair permanent solutions. Do not allow anyone else to use this medication. Do not use other medications with RETIN-A which are not recommended by your doctor. The medications you have used in the past might cause unnecessary redness or peeling. If you are pregnant, think you are pregnant or are nursing an infant: No studies have been conducted in humans to establish the safety of RETIN-A in pregnant women. If you are pregnant, think you are pregnant, or are nursing a baby, consult your physician before using the medication. AND WHILE YOU’RE ON RETIN-A THERAPY Use a mild, non-medicated soap. Avoid frequent washings and harsh scrubbing. Acne isn’t caused by dirt, so no matter how hard you scrub, you can’t wash it away. Washing too frequently or scrubbing too roughly may at times actually make your acne worse. Wash your skin gently with a mild bland soap. (Two or three times a day should be sufficient). Pat skin dry with a towel. Let the face dry 20-30 minutes before applying RETIN-A. Remember, This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda excessive irritation such as rubbing, too much washing, use of other medications not suggested by your physician, etc., may worsen your acne. HOW TO USE RETIN-A (TRETINOIN) To get the best results with RETIN-A therapy, it is necessary to use it properly. Forget about the instructions given for other products and the advice of friends. Just stick to the special plan your doctor has laid out for you and be patient. Remember, when RETIN-A is used properly, many users see improvement by 12 weeks. AGAIN, FOLLOW INSTRUCTIONS - BE PATIENT - DON’T START AND STOP THERAPY ON YOUR OWN - IF YOU HAVE QUESTIONS, ASK YOU DOCTOR. To help you use the medication correctly, keep these simple instructions in mind. (Insert picture) • Apply RETIN-A once daily before bedtime, or as directed by your physician. Your physician may advise, especially if your skin is sensitive, that you start your therapy by applying RETIN-A every other night. First, wash with a mild soap and dry your skin gently. WAIT 20 TO 30 MINUTES BEFORE APPLYING MEDICATION; it is important for skin to be completely dry in order to minimize possible irritation. • It is better not to use more than the amount suggested by your physician or to apply more frequently than instructed. Too much may irritate the skin, waste medication and won’t give faster or better results. • Keep the medication away from the corners of the nose, mouth, eyes and open wounds. Spread away from these areas when applying. • RETIN-A Cream: Squeeze about a half inch or less of medication onto the fingertip. While that should be enough for your whole face, after you have some experience with the medication you may find you need slightly more or less to do the job. The medication should become invisible almost immediately. If it is still visible, you are using too much. Cover the affected area lightly with RETIN-A (tretinoin cream) Cream by first dabbing it on your forehead, chin and both cheeks, then spreading it over the entire affected area. Smooth gently into the skin. • RETIN-A Gel: Squeeze about a half inch or less of medication onto the fingertip. While that should be enough for your whole face, after you have some experience with the medication you may find you need slightly more or less to do the job. The medication should become invisible almost immediately. If it is still visible, or if dry flaking occurs from the gel within a minute or so, you are using too much. Cover the affected area lightly with RETIN-A (tretinoin gel) Gel by first dabbing it on your forehead, chin and both cheeks, then spreading it over the entire affected are. Smooth gently into the skin. This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda • RETIN-A Liquid. RETIN-A (tretinoin liquid) Liquid may be applied to the skin where acne lesions appear, spreading the medication over the entire affected area, using a fingertip, gauze pad, or cotton swab. If gauze or cotton is employed, care should be taken not to oversaturate it to the extent that the liquid would run into area where treatment is not intended (such as corners of the mouth, eyes, and nose). • It is recommended that you apply a moisturizer or a moisturizer with sunscreen that will not aggravate your acne (noncomedogenic) every morning after you wash. WHAT TO EXPECT WITH YOUR NEW TREATMENT RETIN-A works deep inside your skin and this takes time. You cannot make RETIN-A work any faster by applying more than one dose each day, but an excess amount of RETIN-A may irritate your skin. Be patient. There may be some discomfort or peeling during the early days of treatment. Some patients also notice that their skin begins to take on a blush. These reactions do not happen to everyone. If they do, it is just your skin adjusting to RETIN-A and this usually subsides within two to four weeks. These reactions can usually be minimized by following instructions carefully. Should the effects become excessively troublesome, consult your doctor. BY THREE TO SIX WEEKS, some patients notice an appearance of new blemishes (papules and pustules). At this stage it is important to continue using RETIN-A. If RETIN-A is going to have a beneficial effect for you, you should notice a continued improvement in your appearance after 6 to 12 weeks of therapy. Don’t be discouraged if you see no immediate improvement. Don’t stop treatment at the first signs of improvement. Once your acne is under control you should continue regular application of RETIN-A until your physician instructs otherwise. IF YOU HAVE QUESTIONS This label may not be the latest approved by FDA.

SINEQUAN® (doxepin HCl) CAPSULES ORAL CONCENTRATE Suicidality and Antidepressant Drugs Antidepressants increased the risk compared to placebo of suicidal thinking and behavior (suicidality) in children, adolescents, and young adults in short-term studies of major depressive disorder (MDD) and other psychiatric disorders. Anyone considering the use of Sinequan or any other antidepressant in a child, adolescent, or young adult must balance this risk with the clinical need. Short-term studies did not show an increase in the risk of suicidality with antidepressants compared to placebo in adults beyond age 24; there was a reduction in risk with antidepressants compared to placebo in adults aged 65 and older. Depression and certain other psychiatric disorders are themselves associated with increases in the risk of suicide. Patients of all ages who are started on antidepressant therapy should be monitored appropriately and observed closely for clinical worsening, suicidality, or unusual changes in behavior. Families and caregivers should be advised of the need for close observation and communication with the prescriber. Sinequan is not approved for use in pediatric patients. (See Warnings: Clinical Worsening and Suicide Risk, Precautions: Information for Patients, and Precautions: Pediatric Use) DESCRIPTION SINEQUAN® (doxepin hydrochloride) is one of a class of psychotherapeutic agents known as dibenzoxepin tricyclic compounds. The molecular formula of the compound is C19H21NO•HCl having a molecular weight of 316. It is a white crystalline solid readily soluble in water, lower alcohols and chloroform. Inert ingredients for the capsule formulations are: hard gelatin capsules (which may contain Blue 1, Red 3, Red 40, Yellow 10, and other inert ingredients); magnesium stearate; sodium lauryl sulfate; starch. Inert ingredients for the oral concentrate formulation are: glycerin; methylparaben; peppermint oil; propylparaben; water. 1 Reference ID: 3592606 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda CHEMISTRY SINEQUAN (doxepin HCl) is a dibenzoxepin derivative and is the first of a family of tricyclic psychotherapeutic agents. Specifically, it is an isomeric mixture of: 1-Propanamine, 3-dibenz[b,e]oxepin-11(6H)ylidene-N,N-dimethyl-, hydrochloride. structural formula ACTIONS The mechanism of action of SINEQUAN (doxepin HCl) is not definitely known. It is not a central nervous system stimulant nor a monoamine oxidase inhibitor. The current hypothesis is that the clinical effects are due, at least in part, to influences on the adrenergic activity at the synapses so that deactivation of norepinephrine by reuptake into the nerve terminals is prevented. Animal studies suggest that doxepin HCl does not appreciably antagonize the antihypertensive action of guanethidine. In animal studies anticholinergic, antiserotonin and antihistamine effects on smooth muscle have been demonstrated. At higher than usual clinical doses, norepinephrine response was potentiated in animals. This effect was not demonstrated in humans. At clinical dosages up to 150 mg per day, SINEQUAN can be given to man concomitantly with guanethidine and related compounds without blocking the antihypertensive effect. At dosages above 150 mg per day blocking of the antihypertensive effect of these compounds has been reported. SINEQUAN is virtually devoid of euphoria as a side effect. Characteristic of this type of compound, SINEQUAN has not been demonstrated to produce the physical tolerance or psychological dependence associated with addictive compounds. INDICATIONS SINEQUAN is recommended for the treatment of: 1. Psychoneurotic patients with depression and/or anxiety. 2. Depression and/or anxiety associated with alcoholism (not to be taken concomitantly with alcohol). 3. Depression and/or anxiety associated with organic disease (the possibility of drug interaction should be considered if the patient is receiving other drugs concomitantly). 2 Reference ID: 3592606 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda 4. Psychotic depressive disorders with associated anxiety including involutional depression and manic-depressive disorders. The target symptoms of psychoneurosis that respond particularly well to SINEQUAN include anxiety, tension, depression, somatic symptoms and concerns, sleep disturbances, guilt, lack of energy, fear, apprehension and worry. Clinical experience has shown that SINEQUAN is safe and well tolerated even in the elderly patient. Owing to lack of clinical experience in the pediatric population, SINEQUAN is not recommended for use in children under 12 years of age. CONTRAINDICATIONS SINEQUAN is contraindicated in individuals who have shown hypersensitivity to the drug. Possibility of cross sensitivity with other dibenzoxepines should be kept in mind. SINEQUAN is contraindicated in patients with glaucoma or a tendency to urinary retention. These disorders should be ruled out, particularly in older patients. WARNINGS Clinical Worsening and Suicide Risk Patients with major depressive disorder (MDD), both adult and pediatric, may experience worsening of their depression and/or the emergence of suicidal ideation and behavior (suicidality) or unusual changes in behavior, whether or not they are taking antidepressant medications, and this risk may persist until significant remission occurs. Suicide is a known risk of depression and certain other psychiatric disorders, and these disorders themselves are the strongest predictors of suicide. There has been a long-standing concern, however, that antidepressants may have a role in inducing worsening of depression and the emergence of suicidality in certain patients during the early phases of treatment. Pooled analyses of short-term placebo-controlled trials of antidepressant drugs (SSRIs and others) showed that these drugs increase the risk of suicidal thinking and behavior (suicidality) in children,adolescents, and young adults (ages 18-24) with major depressive disorder (MDD) and other psychiatric disorders. Short-term studies did not show an increase in the risk of suicidality with antidepressants compared to placebo in adults beyond age 24; there was a reduction with antidepressants compared to placebo in adults aged 65 and older. The pooled analyses of placebo-controlled trials in children and adolescents with MDD, obsessive compulsive disorder (OCD), or other psychiatric disorders included a total of 24 short- term trials of 9 antidepressant drugs in over 4400 patients. The pooled analyses of placebo- controlled trials in adults with MDD or other psychiatric disorders included a total of 295 short- term trials (median duration of 2 months) of 11 antidepressant drugs in over 77,000 patients. There was considerable variation in risk of suicidality among drugs, but a tendency toward an increase in the younger patients for almost all drugs studied. There were differences in absolute risk of suicidality across the different indications, with the highest incidence in MDD. The risk 3 Reference ID: 3592606 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda differences (drug vs placebo), however, were relatively stable within age strata and across indications. These risk differences (drug-placebo difference in the number of cases of suicidality per 1000 patients treated) are provided in Table 1. Table 1 Age Range Drug-Placebo Difference in Number of Cases of Suicidality per 1000 Patients Treated Increases Compared to Placebo <18 14 additional cases 18-24 5 additional cases Decreases Compared to Placebo 25-64 1 fewer case ≥65 6 fewer cases No suicides occurred in any of the pediatric trials. There were suicides in the adult trials, but the number was not sufficient to reach any conclusion about drug effect on suicide. It is unknown whether the suicidality risk extends to longer-term use, i.e., beyond several months. However, there is substantial evidence from placebo-controlled maintenance trials in adults with depression that the use of antidepressants can delay the recurrence of depression. All patients being treated with antidepressants for any indication should be monitored appropriately and observed closely for clinical worsening, suicidality, and unusual changes in behavior, especially during the initial few months of a course of drug therapy, or at times of dose changes, either increases or decreases. The following symptoms, anxiety, agitation, panic attacks, insomnia, irritability, hostility, aggressiveness, impulsivity, akathisia (psychomotor restlessness), hypomania, and mania, have been reported in adult and pediatric patients being treated with antidepressants for major depressive disorder as well as for other indications, both psychiatric and nonpsychiatric. Although a causal link between the emergence of such symptoms and either the worsening of depression and/or the emergence of suicidal impulses has not been established, there is concern that such symptoms may represent precursors to emerging suicidality. Consideration should be given to changing the therapeutic regimen, including possibly discontinuing the medication, in patients whose depression is persistently worse, or who are experiencing emergent suicidality or symptoms that might be precursors to worsening depression or suicidality, especially if these symptoms are severe, abrupt in onset, or were not part of the patient's presenting symptoms. Families and caregivers of patients being treated with antidepressants for major depressive disorder or other indications, both psychiatric and nonpsychiatric, should be alerted about the need to monitor patients for the emergence of agitation, irritability, unusual changes in behavior, and the other symptoms described above, as well as the emergence of suicidality, and to report such symptoms immediately to health care providers Such monitoring should 4 Reference ID: 3592606 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda include daily observation by families and caregivers. Prescriptions for Sinequan should be written for the smallest quantity of tablets consistent with good patient management, in order to reduce the risk of overdose. Screening Patients for Bipolar Disorder: A major depressive episode may be the initial presentation of bipolar disorder. It is generally believed (though not established in controlled trials) that treating such an episode with an antidepressant alone may increase the likelihood of precipitation of a mixed/manic episode in patients at risk for bipolar disorder. Whether any of the symptoms described above represent such a conversion is unknown. However, prior to initiating treatment with an antidepressant, patients with depressive symptoms should be adequately screened to determine if they are at risk for bipolar disorder; such screening should include a detailed psychiatric history, including a family history of suicide, bipolar disorder, and depression. It should be noted that Sinequan is not approved for use in treating bipolar depression. Angle-Closure Glaucoma: The pupillary dilation that occurs following use of many antidepressant drugs including Sinequan may trigger an angle closure attack in a patient with anatomically narrow angles who does not have a patent iridectomy. Usage in Geriatrics: The use of SINEQUAN on a once-a-day dosage regimen in geriatric patients should be adjusted carefully based on the patient’s condition (see PRECAUTIONS−Geriatric Use). Usage in Pregnancy: Reproduction studies have been performed in rats, rabbits, monkeys and dogs and there was no evidence of harm to the animal fetus. The relevance to humans is not known. Since there is no experience in pregnant women who have received this drug, safety in pregnancy has not been established. There has been a report of apnea and drowsiness occurring in a nursing infant whose mother was taking SINEQUAN. Usage in Children: The use of SINEQUAN in children under 12 years of age is not recommended because safe conditions for its use have not been established. PRECAUTIONS Information for Patients Prescribers or other health professionals should inform patients, their families, and their caregivers about the benefits and risks associated with treatment with Sinequan and should counsel them in its appropriate use. A patient Medication Guide about “Antidepressant Medicines, Depression and other Serious Mental Illness, and Suicidal Thoughts or Actions” is available for Sinequan. The prescriber or health professional should instruct patients, their families, and their caregivers to read the Medication Guide and should assist them in understanding its contents. Patients should be given the opportunity to discuss the contents of the 5 Reference ID: 3592606 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda Medication Guide and to obtain answers to any questions they may have. The complete text of the Medication Guide is reprinted at the end of this document. Patients should be advised of the following issues and asked to alert their prescriber if these occur while taking Sinequan. Clinical Worsening and Suicide Risk: Patients, their families, and their caregivers should be encouraged to be alert to the emergence of anxiety, agitation, panic attacks, insomnia, irritability, hostility, aggressiveness, impulsivity, akathisia (psychomotor restlessness), hypomania, mania, other unusual changes in behavior, worsening of depression, and suicidal ideation, especially early during antidepressant treatment and when the dose is adjusted up or down. Families and caregivers of patients should be advised to look for the emergence of such symptoms on a day-to­ day basis, since changes may be abrupt. Such symptoms should be reported to the patient's prescriber or health professional, especially if they are severe, abrupt in onset, or were not part of the patient's presenting symptoms. Symptoms such as these may be associated with an increased risk for suicidal thinking and behavior and indicate a need for very close monitoring and possibly changes in the medication. Patients should be advised that taking Sinequan can cause mild pupillary dilation, which in susceptible individuals, can lead to an episode of angle closure glaucoma. Pre-existing glaucoma is almost always open-angle glaucoma because angle closure glaucoma, when diagnosed, can be treated definitively with iridectomy. Open-angle glaucoma is not a risk factor for angle closure glaucoma. Patients may wish to be examined to determine whether they are susceptible to angle closure, and have a prophylactic procedure (e.g., iridectomy), if they are susceptible. Pediatric Use-Safety and effectiveness in the pediatric population have not been established (see BOX WARNING and WARNINGS—Clinical Worsening and Suicide Risk). Anyone considering the use of SINEQUAN in a child or adolescent must balance the potential risks with the clinical need. Drug Interactions: Drugs Metabolized by P450 2D6: The biochemical activity of the drug metabolizing isozyme cytochrome P450 2D6 (debrisoquin hydroxylase) is reduced in a subset of the Caucasian population (about 7–10% of Caucasians are so-called “poor metabolizers”); reliable estimates of the prevalence of reduced P450 2D6 isozyme activity among Asian, African and other populations are not yet available. Poor metabolizers have higher than expected plasma concentrations of tricyclic antidepressants (TCAs) when given usual doses. Depending on the fraction of drug metabolized by P450 2D6, the increase in plasma concentration may be small, or quite large (8-fold increase in plasma AUC of the TCA). In addition, certain drugs inhibit the activity of this isozyme and make normal metabolizers resemble poor metabolizers. An individual who is stable on a given dose of TCA may become abruptly toxic when given one of these inhibiting drugs as concomitant therapy. The drugs that 6 Reference ID: 3592606 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda inhibit cytochrome P450 2D6 include some that are not metabolized by the enzyme (quinidine; cimetidine) and many that are substrates for P450 2D6 (many other antidepressants, phenothiazines, and the Type 1C antiarrhythmics propafenone and flecainide). While all the selective serotonin reuptake inhibitors (SSRIs), e.g., citalopram, escitalopram, fluoxetine, sertraline, and paroxetine, inhibit P450 2D6, they may vary in the extent of inhibition. The extent to which SSRI-TCA interactions may pose clinical problems will depend on the degree of inhibition and the pharmacokinetics of the SSRI involved. Nevertheless, caution is indicated in the co-administration of TCAs with any of the SSRIs and also in switching from one class to the other. Of particular importance, sufficient time must elapse before initiating TCA treatment in a patient being withdrawn from fluoxetine, given the long half-life of the parent and active metabolite (at least 5 weeks may be necessary). Concomitant use of tricyclic antidepressants with drugs that can inhibit cytochrome P450 2D6 may require lower doses than usually prescribed for either the tricyclic antidepressant or the other drug. Furthermore, whenever one of these other drugs is withdrawn from co-therapy, an increased dose of tricyclic antidepressant may be required. It is desirable to monitor TCA plasma levels whenever a TCA is going to be co-administered with another drug known to be an inhibitor of P450 2D6. Doxepin is primarily metabolized by CYP2D6 (with CYP1A2 & CYP3A4 as minor pathways). Inhibitors or substrates of CYP2D6 (i.e., quinidine, selective serotonin reuptake inhibitors [SSRIs]) may increase the plasma concentration of doxepin when administered concomitantly. The extent of interaction depends on the variability of effect on CYP2D6. The clinical significance of this interaction with doxepin has not been systematically evaluated. MAO Inhibitors: Serious side effects and even death have been reported following the concomitant use of certain drugs with MAO inhibitors. Therefore, MAO inhibitors should be discontinued at least two weeks prior to the cautious initiation of therapy with SINEQUAN. The exact length of time may vary and is dependent upon the particular MAO inhibitor being used, the length of time it has been administered, and the dosage involved. Cimetidine: Cimetidine has been reported to produce clinically significant fluctuations in steady-state serum concentrations of various tricyclic antidepressants. Serious anticholinergic symptoms (i.e., severe dry mouth, urinary retention and blurred vision) have been associated with elevations in the serum levels of tricyclic antidepressant when cimetidine therapy is initiated. Additionally, higher than expected tricyclic antidepressant levels have been observed when they are begun in patients already taking cimetidine. In patients who have been reported to be well controlled on tricyclic antidepressants receiving concurrent cimetidine therapy, discontinuation of cimetidine has been reported to decrease established steady-state serum tricyclic antidepressant levels and compromise their therapeutic effects. Alcohol: It should be borne in mind that alcohol ingestion may increase the danger inherent in any intentional or unintentional SINEQUAN overdosage. This is especially important in patients who may use alcohol excessively. 7 Reference ID: 3592606 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda Tolazamide: A case of severe hypoglycemia has been reported in a type II diabetic patient maintained on tolazamide (1 gm/day) 11 days after the addition of doxepin (75 mg/day). Drowsiness: Since drowsiness may occur with the use of this drug, patients should be warned of the possibility and cautioned against driving a car or operating dangerous machinery while taking the drug. Patients should also be cautioned that their response to alcohol may be potentiated. Sedating drugs may cause confusion and oversedation in the elderly; elderly patients generally should be started on low doses of SINEQUAN and observed closely. (See PRECAUTIONS−Geriatric Use.) Suicide: Since suicide is an inherent risk in any depressed patient and may remain so until significant improvement has occurred, patients should be closely supervised during the early course of therapy. Prescriptions should be written for the smallest feasible amount. Psychosis: Should increased symptoms of psychosis or shift to manic symptomatology occur, it may be necessary to reduce dosage or add a major tranquilizer to the dosage regimen. Geriatric Use: A determination has not been made whether controlled clinical studies of SINEQUAN included sufficient numbers of subjects aged 65 and over to define a difference in response from younger subjects. Other reported clinical experience has not identified differences in responses between the elderly and younger patients. In general, dose selection for an elderly patient should be cautious, usually starting at the low end of the dosing range, reflecting the greater frequency of decreased hepatic, renal or cardiac function, and of concomitant disease or other drug therapy. The extent of renal excretion of SINEQUAN has not been determined. Because elderly patients are more likely to have decreased renal function, care should be taken in dose selections. Sedating drugs may cause confusion and oversedation in the elderly; elderly patients generally should be started on low doses of SINEQUAN and observed closely. (See WARNINGS.) ADVERSE REACTIONS NOTE: Some of the adverse reactions noted below have not been specifically reported with SINEQUAN use. However, due to the close pharmacological similarities among the tricyclics, the reactions should be considered when prescribing SINEQUAN (doxepin HCl). Anticholinergic Effects: Dry mouth, blurred vision, constipation, and urinary retention have been reported. If they do not subside with continued therapy, or become severe, it may be necessary to reduce the dosage. Central Nervous System Effects: Drowsiness is the most commonly noticed side effect. This tends to disappear as therapy is continued. Other infrequently reported CNS side effects are confusion, disorientation, hallucinations, numbness, paresthesias, ataxia, extrapyramidal symptoms, seizures, tardive dyskinesia, and tremor. 8 Reference ID: 3592606 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda Cardiovascular: Cardiovascular effects including hypotension, hypertension, and tachycardia have been reported occasionally. Allergic: Skin rash, edema, photosensitization, and pruritus have occasionally occurred. Hematologic: Eosinophilia has been reported in a few patients. There have been occasional reports of bone marrow depression manifesting as agranulocytosis, leukopenia, thrombocytopenia, and purpura. Gastrointestinal: Nausea, vomiting, indigestion, taste disturbances, diarrhea, anorexia, and aphthous stomatitis have been reported. (See Anticholinergic Effects.) Endocrine: Raised or lowered libido, testicular swelling, gynecomastia in males, enlargement of breasts and galactorrhea in the female, raising or lowering of blood sugar levels, and syndrome of inappropriate antidiuretic hormone secretion have been reported with tricyclic administration. Other: Dizziness, tinnitus, weight gain, sweating, chills, fatigue, weakness, flushing, jaundice, alopecia, headache, exacerbation of asthma, angle closure glaucoma, mydriasis and hyperpyrexia (in association with chlorpromazine) have been occasionally observed as adverse effects. Withdrawal Symptoms: The possibility of development of withdrawal symptoms upon abrupt cessation of treatment after prolonged SINEQUAN administration should be borne in mind. These are not indicative of addiction and gradual withdrawal of medication should not cause these symptoms. DOSAGE AND ADMINISTRATION For most patients with illness of mild to moderate severity, a starting daily dose of 75 mg is recommended. Dosage may subsequently be increased or decreased at appropriate intervals and according to individual response. The usual optimum dose range is 75 mg/day to 150 mg/day. In more severely ill patients higher doses may be required with subsequent gradual increase to 300 mg/day if necessary. Additional therapeutic effect is rarely to be obtained by exceeding a dose of 300 mg/day. In patients with very mild symptomatology or emotional symptoms accompanying organic disease, lower doses may suffice. Some of these patients have been controlled on doses as low as 25–50 mg/day. The total daily dosage of SINEQUAN may be given on a divided or once-a-day dosage schedule. If the once-a-day schedule is employed, the maximum recommended dose is 150 mg/day. This dose may be given at bedtime. The 150 mg capsule strength is intended for maintenance therapy only and is not recommended for initiation of treatment. 9 Reference ID: 3592606 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda Anti-anxiety effect is apparent before the antidepressant effect. Optimal antidepressant effect may not be evident for two to three weeks. OVERDOSAGE Deaths may occur from overdosage with this class of drugs. Multiple drug ingestion (including alcohol) is common in deliberate tricyclic antidepressant overdose. As the management is complex and changing, it is recommended that the physician contact a poison control center for current information on treatment. Signs and symptoms of toxicity develop rapidly after tricyclic antidepressant overdose; therefore, hospital monitoring is required as soon as possible. Manifestations: Critical manifestations of overdose include: cardiac dysrhythmias, severe hypotension, convulsions, and CNS depression, including coma. Changes in the electrocardiogram, particularly in QRS axis or width, are clinically significant indicators of tricyclic antidepressant toxicity. Other signs of overdose may include: confusion, disturbed concentration, transient visual hallucinations, dilated pupils, agitation, hyperactive reflexes, stupor, drowsiness, muscle rigidity, vomiting, hypothermia, hyperpyrexia, or any of the symptoms listed under ADVERSE REACTIONS. Deaths have been reported involving overdoses of doxepin. General Recommendations: General: Obtain an ECG and immediately initiate cardiac monitoring. Protect the patient’s airway, establish an intravenous line and initiate gastric decontamination. A minimum of six hours of observation with cardiac monitoring and observation for signs of CNS or respiratory depression, hypotension, cardiac dysrhythmias and/or conduction blocks, and seizures is strongly advised. If signs of toxicity occur at any time during this period, extended monitoring is recommended. There are case reports of patients succumbing to fatal dysrhythmias late after overdose; these patients had clinical evidence of significant poisoning prior to death and most received inadequate gastrointestinal decontamination. Monitoring of plasma drug levels should not guide management of the patient. Gastrointestinal Decontamination: All patients suspected of tricyclic antidepressant overdose should receive gastrointestinal decontamination. This should include large volume gastric lavage followed by activated charcoal. If consciousness is impaired, the airway should be secured prior to lavage. Emesis is contraindicated. Cardiovascular: A maximal limb-lead QRS duration of ≥0.10 seconds may be the best indication of the severity of the overdose. Intravenous sodium bicarbonate should be used to maintain the serum pH in the range of 7.45 to 7.55. If the pH response is inadequate, hyperventilation may also be used. Concomitant use of hyperventilation and sodium bicarbonate should be done with extreme caution, with frequent pH monitoring. A pH >7.60 or a pCO2 <20 mm Hg is undesirable. Dysrhythmias unresponsive to sodium bicarbonate 10 Reference ID: 3592606 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda therapy/hyperventilation may respond to lidocaine, bretylium or phenytoin. Type 1A and 1C antiarrhythmics are generally contraindicated (e.g., quinidine, disopyramide, and procainamide). In rare instances, hemoperfusion may be beneficial in acute refractory cardiovascular instability in patients with acute toxicity. However, hemodialysis, peritoneal dialysis, exchange transfusions, and forced diuresis generally have been reported as ineffective in tricyclic antidepressant poisoning. CNS: In patients with CNS depression, early intubation is advised because of the potential for abrupt deterioration. Seizures should be controlled with benzodiazepines, or if these are ineffective, other anticonvulsants (e.g., phenobarbital, phenytoin). Physostigmine is not recommended except to treat life-threatening symptoms that have been unresponsive to other therapies, and then only in consultation with a poison control center. Psychiatric Follow-up: Since overdosage is often deliberate, patients may attempt suicide by other means during the recovery phase. Psychiatric referral may be appropriate. Pediatric Management: The principles of management of child and adult overdosages are similar. It is strongly recommended that the physician contact the local poison control center for specific pediatric treatment.

This Medication Guide is only about the risk of suicidal thoughts and actions with antidepressant medicines. Talk to your, or your family member’s, healthcare provider about: • all risks and benefits of treatment with antidepressant medicines • all treatment choices for depression or other serious mental illness What is the most important information I should know about antidepressant medicines, depression and other serious mental illnesses, and suicidal thoughts or actions? 1. Antidepressant medicines may increase suicidal thoughts or actions in some children, teenagers, and young adults within the first few months of treatment. 2. Depression and other serious mental illnesses are the most important causes of suicidal thoughts and actions. Some people may have a particularly high risk of having suicidal thoughts or actions. These include people who have (or have a family history of) bipolar illness (also called manic-depressive illness) or suicidal thoughts or actions. 3. How can I watch for and try to prevent suicidal thoughts and actions in myself or a family member? • Pay close attention to any changes, especially sudden changes, in mood, behaviors, thoughts, or feelings. This is very important when an antidepressant medicine is started or when the dose is changed. • Call the healthcare provider right away to report new or sudden changes in mood, behavior, thoughts, or feelings. • Keep all follow-up visits with the healthcare provider as scheduled. Call the healthcare provider between visits as needed, especially if you have concerns about symptoms. Call a healthcare provider right away if you or your family member has any of the following symptoms, especially if they are new, worse, or worry you: • thoughts about suicide or dying • an extreme increase in activity and • attempts to commit suicide talking (mania)other unusual changes • new or worse depression in behavior or mood • new or worse anxiety • Visual problems • feeling very agitated or restless • eye pain • panic attacks • changes in vision • trouble sleeping (insomnia) • swelling or redness in or • new or worse irritability around the eye • acting aggressive, being angry, or Only some people are at risk for violent these problems. You may want to • acting on dangerous impulses undergo an eye examination to 13 Reference ID: 3592606 This label may not be the latest approved by FDA.

Call your doctor for medical advice about side effects. You may report side effects to FDA at 1-800-FDA-1088. What else do I need to know about antidepressant medicines? • Never stop an antidepressant medicine without first talking to a healthcare provider. Stopping an antidepressant medicine suddenly can cause other symptoms. • Antidepressants are medicines used to treat depression and other illnesses. It is important to discuss all the risks of treating depression and also the risks of not treating it. Patients and their families or other caregivers should discuss all treatment choices with the healthcare provider, not just the use of antidepressants. • Antidepressant medicines have other side effects. Talk to the healthcare provider about the side effects of the medicine prescribed for you or your family member. • Antidepressant medicines can interact with other medicines. Know all of the medicines that you or your family member takes. Keep a list of all medicines to show the healthcare provider. Do not start new medicines without first checking with your healthcare provider. • Not all antidepressant medicines prescribed for children are FDA approved for use in children. Talk to your child’s healthcare provider for more information. This Medication Guide has been approved by the U.S. Food and Drug Administration for all antidepressants.

RETIN-A® Cream Gel Liquid (tretinoin) For Topical Use Only Prescribing Information Description: RETIN-A Gel, Cream, and Liquid, containing tretinoin are used for the topical treatment of acne vulgaris. RETIN-A Gel contains tretinoin (retinoic acid, vitamin A acid) in either of two strengths, 0.025% or 0.01% by weight, in a gel vehicle of butyl alcohol, hydroxypropyl cellulose and alcohol (denatured with tert- butylated hydroxytoluene, and brucine sulfate) 90% w/w. RETIN-A (tretinoin) Cream contains tretinoin in either of three strengths, 0.1%, 0.05%, or 0.025% by weight, in a hydrophilic cream vehicle of stearic acid, isopropyl myristate, polyoxyl 40 stearate, stearyl alcohol, xanthan gum, sorbic acid, butylated hydroxytoluene, and purified water. RETIN-A Liquid contains tretinoin 0.05% by weight, polyethylene glycol 400, butylated hydroxytoluene and alcohol (denatured with tert-butyl alcohol and brucine sulfate) 55%. Chemically, tretinoin is all-trans-retinoic acid and has the following structure: Leave space for structure. Clinical Pharmacology: Although the exact mode of action of tretinoin is unknown, current evidence suggests that topical tretinoin decreases cohesiveness of follicular epithelial cells with decreased microcomedo formation. Additionally, tretinoin stimulates mitotic activity and increased turnover of follicular epithelial cells causing extrusion of the comedones. Indications and Usage: RETIN-A is indicated for topical application in the treatment of acne vulgaris. The safety and efficacy of the long-term use of this product in the treatment of other disorders have not been established. Contraindications: Use of the product should be discontinued if hypersensitivity to any of the ingredients is noted. Warnings: GELS ARE FLAMMABLE. AVOID FIRE, FLAME OR SMOKING DURING USE. Keep out of reach of children. Keep tube tightly closed. Do not expose to heat or store at temperatures above 120°F (49°C). This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda Precautions: General: If a reaction suggesting sensitivity or chemical irritation occurs, use of the medication should be discontinued. Exposure to sunlight, including sunlamps, should be minimized during the use of RETIN- A, and patients with sunburn should be advised not to use the product until fully recovered because of heightened susceptibility to sunlight as a result of the use of tretinoin. Patients who may be required to have considerable sun exposure due to occupation and those with inherent sensitivity to the sun should exercise particular caution. Use of sunscreen products and protective clothing over treated areas is recommended when exposure cannot be avoided. Weather extremes, such as wind or cold, also may be irritating to patients under treatment with tretinoin. RETIN-A (tretinoin) acne treatment should be kept away from the eyes, the mouth, angles of the nose, and mucous membranes. Topical use may induce severe local erythema and peeling at the site of application. If the degree of local irritation warrants, patients should be directed to use the medication less frequently, discontinue use temporarily, or discontinue use altogether. Tretinoin has been reported to cause severe irritation on eczematous skin and should be used with utmost caution in patients with this condition. Drug Interactions: Concomitant topical medication, medicated or abrasive soaps and cleansers, soaps and cosmetics that have a strong drying effect, and products with high concentrations of alcohol, astringents, spices or lime should be used with caution because of possible interaction with tretinoin. Particular caution should be exercised in using preparations containing sulfur, resorcinol, or salicylic acid with RETIN-A. It also is advisable to “rest” a patient’s skin until the effects of such preparations subside before use of RETIN-A is begun. Carcinogenesis, Mutagenesis, Impairment to Fertility: In a 91-week dermal study in which CD-1 mice were administered 0.017% and 0.035% formulations of tretinoin, cutaneous squamous cell carcinomas and papillomas in the treatment area were observed in some female mice. A dose-related incidence of liver tumors in male mice was observed at those same doses. The maximum systemic doses associated with the administered 0.017% and 0.035% formulations are 0.5 and 1.0 mg/kg/day, respectively. These doses are two and four times the maximum human systemic dose, when adjusted for total body surface area. The biological significance of these findings is not clear because they occurred at doses that exceeded the dermal maximally tolerated dose (MTD) of tretinoin and because they were within the background natural occurrence rate for these tumors in this strain of mice. There was no evidence of carcinogenic potential when 0.025 mg/kg/day of tretinoin was administered topically to mice (0.1 times the maximum human systemic dose, adjusted for total body surface area). For purposes of comparisons of the animal exposure to systemic human exposure, the maximum human systemic dose is defined as 1 gram of 0.1% RETIN-A applied daily to a 50 kg person (0.02 mg tretinoin/kg body weight). This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda Studies in hairless albino mice suggest that concurrent exposure to tretinoin may enhance the tumorigenic potential of carcinogenic doses of UVB and UVA light form a solar simulator. This effect has been confirmed in a later study in pigmented mice, and dark pigmentation did not overcome the enhancement of photocarcinogenesis by 0.05% tretinoin. Although the significance of these studies to humans is not clear, patients should minimize exposure to sunlight or artificial ultraviolet irradiation sources. The mutagenic potential of tretinoin was evaluated in the Ames assay and in the in vivo mouse micronucleus assay, both of which were negative. In dermal Segment I fertility studies of another tretinoin formulation in rats, slight (not statistically significant) decreases in sperm count and motility were seen at 0.5 mg/kg/day (4 times the maximum human systemic dose adjusted for total body surface area), and slight (not statistically significant) increases in the number and percent of nonviable embryos in females treated with 0.25 mg/kg/day (2 times the maximum human systemic dose adjusted for total body surface area) and above were observed. A dermal Segment III study with RETIN-A has not been performed in any species. In oral Segment I and Segment III studies in rats with tretinoin, decreased survival of neonates and growth retardation were observed at doses in excess of 2 mg/kg/day (16 times the human topical does adjusted for total body surface area). Pregnancy: Teratogenic effects. Pregnancy Category C. Oral tretinoin has been shown to be teratogenic in rats, mice, hamsters, and subhuman primates. It was teratogenic and fetotoxic in Wistar rats when given orally or topically in doses greater than 1 mg/kg/day (8 times the maximum human systemic dose adjusted for total body surface area). However, variations in teratogenic doses among various strains of rats have been reported. In the cynomolgus monkey, which metabolically is closer to humans for tretinoin than the other species examined, fetal malformations were reported at doses of 10 mg/kg/day or greater, but none were observed at 5 mg/kg/day (83 times the maximum human systemic does adjusted for total body surface area), although increased skeletal variations were observed at all doses. A dose-related increase in embryolethality and abortion was reported. Similar results have also been reported in pigtail macaques. Topical tretinoin in animal teratogenicity tests has generated equivocal results. There is evidence for teratogenicity (shortened or kinked tail) of topical tretinoin in Wistar rats at doses greater than 1 mg/kg/day (8 times the maximum human systemic dose adjusted for total body surface area). Anomalies (humerus: short 13%, bent 6%, os parietal incompletely ossified 14%) have also been reported when 10 mg/kg/day was topically applied. This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda There are other reports in New Zealand White rabbits administered doses of greater than 0.2 mg/kg/day (3.3 times the maximum human systemic dose adjusted for total body surface area) of an increased incidence of domed head and hydrocephaly, typical of retinoid-induced fetal malformations in this species. In contrast, several well-controlled animals studies have shown that dermally applied tretinoin may be fetoxic, but not overly teratogenic in rats and rabbits at doses of 1.0 and 0.5 mg/kg/day, respectively (8 times the maximum human systemic does adjusted for total body surface area in both species). With widespread use of any drug, a small number of birth defect reports associated temporally with the administration of the drug would be expected by chance alone. Thirty human cases of temporally associated congenital malformations have been reported during two decades of clinical use of RETIN-A. Although no definite pattern of teratogenicity and no causal association has been established from these cases, five of the reports describe the rare birth defect category holoprosencephaly (defects associated with incomplete midline development of the forebrain). The significance of these spontaneous reports in terms of risk to the fetus is not known. Nonteratogenic effects: Topical tretinoin has been shown to be fetotoxic in rabbits when administered 0.5 mg/kg/day (8 times the maximum human systemic dose adjusted for total body surface area). Oral tretinoin has been shown to be fetotoxic, resulting in skeletal variations and increased intrauterine death in rats when administered 2.5 mg/kg/day (20 times the maximum human systemic dose adjusted for total body surface area). There are, however, no adequate and well-controlled studies in pregnant women. Tretinoin should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus. Nursing Mothers: It is not known whether this drug is excreted in human milk. Because many drugs are excreted in human milk, caution should be exercised when RETIN-A is administered to a nursing woman. Pediatric Use: Safety and effectiveness in pediatric patients below the age of 12 have not been established. Geriatric Use: Safety and effectiveness in a geriatric population have not been established. Clinical studies of RETIN-A did not include sufficient numbers of subjects aged 65 and over to determine whether they respond differently from younger patients. This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda Adverse Reactions: The skin of certain sensitive individuals may become excessively red, edematous, blistered, or crusted. If these effects occur, the medication should either be discontinued until the integrity of the skin is restored, or the medication should be adjusted to a level the patient can tolerate. True contact allergy to topical tretinoin is rarely encountered. Temporary hyper- or hypopigmentation has been reported with repeated application of RETIN-A. Some individuals have been reported to have heightened susceptibility to sunlight while under treatment with RETIN-A. To date, all adverse effects of RETIN-A have been reversible upon discontinuance of therapy (see Dosage and Administration Section). Overdosage: If medication is applied excessively, no more rapid or better results will be obtained and marked redness, peeling, or discomfort may occur. Oral ingestion of the drug may lead to the same side effects as those associated with excessive oral intake of Vitamin A. Dosage and Administration: RETIN-A Gel, Cream or Liquid should be applied once a day, before retiring, to the skin where acne lesions appear, using enough to cover the entire affected area lightly. Liquid: the liquid may be applied using a fingertip, gauze pad, or cotton swab. If gauze or cotton is employed, care should be taken not to oversaturate it, to the extent that the liquid would run into areas where treatment is not intended. Gel: Excessive application results in “pilling” of the gel, which minimizes the likelihood of over application by the patient. Application may cause a transitory feeling of warmth or slight stinging. In cases where it has been necessary to temporarily discontinue therapy or to reduce the frequency of application, therapy may be resumed or frequency of application increased when the patients become able to tolerate the treatment. Alteration of vehicle, drug concentration, or dose frequency should be closely monitored by careful observation of the clinical therapeutic response and skin tolerance. During the early weeks of therapy, an apparent exacerbation of inflammatory lesions may occur. This is due to the action of the medication on deep, previously unseen lesions and should not be considered a reason to discontinue therapy. Therapeutic results should be noticed after two to three weeks but more than six weeks of therapy may be required before definite beneficial effects are seen. This label may not be the latest approved by FDA.

THIS PRODUCT IS TO BE USED ONLY ACCORDING TO YOUR DOCTOR’S INSTRUCTIONS, AND IT SHOULD NOT BE APPLIED TO OTHER AREAS OF THE BODY OR TO OTHER GROWTHS OR LESIONS. THE LONG-TERM SAFETY AND EFFECTIVENESS OF THIS PRODUCT IN OTHER DISORDERS HAVE NOT BEEN EVALUATED. IF YOU HAVE ANY QUESTIONS, BE SURE TO ASK YOUR DOCTOR. WARNINGS RETIN- A GELS ARE FLAMMABLE. AVOID FIRE, FLAME OR SMOKING DURING USE. Keep out of reach of children. Keep tube tightly closed. Do not expose to heat or store at temperatures above 120°F (49°C). PRECAUTIONS The effects of the sun on your skin. As you know, overexposure to natural sunlight or the artificial sunlight of a sunlamp can cause sunburn. Overexposure to the sun over many years may cause premature aging of the skin and even skin cancer. The chance of these effects occurring will vary depending on skin type, the climate and the care taken to avoid overexposure to the sun. Therapy with RETIN-A may make your skin more susceptible to sunburn and other adverse effects of the sun, so unprotected exposure to natural or artificial sunlight should be minimized. Laboratory findings. When laboratory mice are exposed to artificial sunlight, they often develop skin tumors. These sunlight-induced tumors may appear more quickly and in greater number if the mouse is also topically treated with the active ingredient in RETIN-A, tretinoin. In some studies, under different conditions, however, when mice treated with tretinoin were exposed to artificial sunlight, the incidence and rate of development of skin tumors was reduced. There is no evidence to date that tretinoin alone will cause the development of skin tumors in either laboratory animals or humans. However, investigations in this area are continuing. Use caution in the sun. When outside, even on hazy days, areas treated with RETIN-A should be protected. An effective sunscreen should be used any time you are outside (consult your physician for a recommendation of an SPF level which will provide you with the necessary high level of protection). For extended sun exposure, protective clothing, like a hat, should be worn. Do not use artificial sunlamps while you are using RETIN-A. If you do become sunburned, stop your therapy with RETIN-A until your skin has recovered. This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda Avoid excessive exposure to wind or cold. Extremes of climate tend to dry or burn normal skin. Skin treated with RETIN-A may be more vulnerable to these extremes. Your physician can recommend ways to manage your acne treatment under such conditions. Possible problems. The skin of certain sensitive individuals may become excessively red, swollen, blistered or crusted. If you are experiencing severe or persistent irritation, discontinues the use of RETIN-A and consult your physician. There have been reports that, in some patients, areas treated with RETIN-A developed a temporary increase or decrease in the amount of skin pigment (color) present. The pigment in these areas returned to normal either when the skin was allowed to adjust to RETIN-A or therapy was discontinued. Use other medication only on your physician’s advice. Only your physician knows which other medications may be helpful during treatment and will recommend them to you if necessary. Follow the physician’s instructions carefully. In addition, you should avoid preparations that may dry or irritate your skin. These preparations may include certain astringents, toiletries containing alcohol, spices or lime, or certain medicated soaps, shampoos and hair permanent solutions. Do not allow anyone else to use this medication. Do not use other medications with RETIN-A which are not recommended by your doctor. The medications you have used in the past might cause unnecessary redness or peeling. If you are pregnant, think you are pregnant or are nursing an infant: No studies have been conducted in humans to establish the safety of RETIN-A in pregnant women. If you are pregnant, think you are pregnant, or are nursing a baby, consult your physician before using the medication. AND WHILE YOU’RE ON RETIN-A THERAPY Use a mild, non-medicated soap. Avoid frequent washings and harsh scrubbing. Acne isn’t caused by dirt, so no matter how hard you scrub, you can’t wash it away. Washing too frequently or scrubbing too roughly may at times actually make your acne worse. Wash your skin gently with a mild bland soap. (Two or three times a day should be sufficient). Pat skin dry with a towel. Let the face dry 20-30 minutes before applying RETIN-A. Remember, This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda excessive irritation such as rubbing, too much washing, use of other medications not suggested by your physician, etc., may worsen your acne. HOW TO USE RETIN-A (TRETINOIN) To get the best results with RETIN-A therapy, it is necessary to use it properly. Forget about the instructions given for other products and the advice of friends. Just stick to the special plan your doctor has laid out for you and be patient. Remember, when RETIN-A is used properly, many users see improvement by 12 weeks. AGAIN, FOLLOW INSTRUCTIONS - BE PATIENT - DON’T START AND STOP THERAPY ON YOUR OWN - IF YOU HAVE QUESTIONS, ASK YOU DOCTOR. To help you use the medication correctly, keep these simple instructions in mind. (Insert picture) • Apply RETIN-A once daily before bedtime, or as directed by your physician. Your physician may advise, especially if your skin is sensitive, that you start your therapy by applying RETIN-A every other night. First, wash with a mild soap and dry your skin gently. WAIT 20 TO 30 MINUTES BEFORE APPLYING MEDICATION; it is important for skin to be completely dry in order to minimize possible irritation. • It is better not to use more than the amount suggested by your physician or to apply more frequently than instructed. Too much may irritate the skin, waste medication and won’t give faster or better results. • Keep the medication away from the corners of the nose, mouth, eyes and open wounds. Spread away from these areas when applying. • RETIN-A Cream: Squeeze about a half inch or less of medication onto the fingertip. While that should be enough for your whole face, after you have some experience with the medication you may find you need slightly more or less to do the job. The medication should become invisible almost immediately. If it is still visible, you are using too much. Cover the affected area lightly with RETIN-A (tretinoin cream) Cream by first dabbing it on your forehead, chin and both cheeks, then spreading it over the entire affected area. Smooth gently into the skin. • RETIN-A Gel: Squeeze about a half inch or less of medication onto the fingertip. While that should be enough for your whole face, after you have some experience with the medication you may find you need slightly more or less to do the job. The medication should become invisible almost immediately. If it is still visible, or if dry flaking occurs from the gel within a minute or so, you are using too much. Cover the affected area lightly with RETIN-A (tretinoin gel) Gel by first dabbing it on your forehead, chin and both cheeks, then spreading it over the entire affected are. Smooth gently into the skin. This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda • RETIN-A Liquid. RETIN-A (tretinoin liquid) Liquid may be applied to the skin where acne lesions appear, spreading the medication over the entire affected area, using a fingertip, gauze pad, or cotton swab. If gauze or cotton is employed, care should be taken not to oversaturate it to the extent that the liquid would run into area where treatment is not intended (such as corners of the mouth, eyes, and nose). • It is recommended that you apply a moisturizer or a moisturizer with sunscreen that will not aggravate your acne (noncomedogenic) every morning after you wash. WHAT TO EXPECT WITH YOUR NEW TREATMENT RETIN-A works deep inside your skin and this takes time. You cannot make RETIN-A work any faster by applying more than one dose each day, but an excess amount of RETIN-A may irritate your skin. Be patient. There may be some discomfort or peeling during the early days of treatment. Some patients also notice that their skin begins to take on a blush. These reactions do not happen to everyone. If they do, it is just your skin adjusting to RETIN-A and this usually subsides within two to four weeks. These reactions can usually be minimized by following instructions carefully. Should the effects become excessively troublesome, consult your doctor. BY THREE TO SIX WEEKS, some patients notice an appearance of new blemishes (papules and pustules). At this stage it is important to continue using RETIN-A. If RETIN-A is going to have a beneficial effect for you, you should notice a continued improvement in your appearance after 6 to 12 weeks of therapy. Don’t be discouraged if you see no immediate improvement. Don’t stop treatment at the first signs of improvement. Once your acne is under control you should continue regular application of RETIN-A until your physician instructs otherwise. IF YOU HAVE QUESTIONS This label may not be the latest approved by FDA.

Tigan® (trimethobenzamide hydrochloride) Capsules/Suppositories/Injectable DESCRIPTION Chemically, trimethobenzamide HCl is N-[p-[2-(dimethylamino)ethoxy]benzyl]- 3,4,5-trimethoxybenz- amide monohydrochloride. It has a molecular weight of 424.93 and the following structural formula: (CH3)2N-CH2CH2O CH2NHC OCH3 OCH3 OCH3 O • HCl Capsules: Each 300-mg Tigan® capsule for oral use contains trimethobenzamide hydrochloride equivalent to 300 mg. The capsule has an opaque purple cap marked “Tigan” and an opaque purple body marked “M079”. Inactive Ingredients: D&C Red No. 28, FD&C Blue No. 1, lactose, magnesium stearate, starch and titanium dioxide. Suppositories (200 mg): Each suppository contains 200 mg trimethobenzamide hydrochloride and 2% benzocaine in a base compounded with polysorbate 80, white beeswax and propylene glycol monostearate. Suppositories, Pediatric (100 mg): Each suppository contains 100 mg trimethobenzamide hydrochloride and 2% benzocaine in a base compounded with polysorbate 80, white beeswax and propylene glycol monostearate. Single-Dose Vials: Each 2-mL single-dose vial contains 200 mg trimethobenzamide hydrochloride compounded with 1 mg sodium citrate and 0.4 mg citric acid as buffers and pH adjusted to approximately 5.0 with sodium hydroxide. Multi-Dose Vials: Each mL contains 100 mg trimethobenzamide hydrochloride compounded with 0.45% phenol as preservative, 0.5 mg sodium citrate and 0.2 mg citric acid as buffers and pH adjusted to approximately 5.0 with sodium hydroxide. This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda CLINICAL PHARMACOLOGY Mechanism of Action The mechanism of action of Tigan® as determined in animals is obscure, but may involve the chemoreceptor trigger zone (CTZ), an area in the medulla oblongata through which emetic impulses are conveyed to the vomiting center; direct impulses to the vomiting center apparently are not similarly inhibited. In dogs pretreated with trimethobenzamide HCl, the emetic response to apomorphine is inhibited, while little or no protection is afforded against emesis induced by intragastric copper sulfate. Pharmacokinetics The pharmacokinetics of trimethobenzamide have been studied in healthy adult subjects. Following administration of 200 mg (100 mg/mL) Tigan I.M. injection, the time to reach maximum plasma concentration (Tmax) was about half an hour, about 15 minutes longer for Tigan 300 mg oral capsule than an I.M. injection. A single dose of Tigan 300 mg oral capsule provided a plasma concentration profile of trimethobenzamide similar to Tigan 200 mg I.M. The relative bioavailability of the capsule formulation compared to the solution is 100%. The mean elimination half-life of trimethobenzamide is 7 to 9 hours. Special Populations Gender Systemic exposure to trimethobenzamide was similar between men (N=40) and women (N=28). Race Pharmacokinetics appeared to be similar for Caucasians (N=53) and African Americans (N=12). INDICATIONS Tigan® is indicated for the treatment of postoperative nausea and vomiting and for nausea associated with gastroenteritis. CONTRAINDICATIONS Use of the injectable form of Tigan® in children, the suppositories in premature or newborn infants, and use of any dosage form in patients with known This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda hypersensitivity to trimethobenzamide are contraindicated. Since the suppositories contain benzocaine they should not be used in patients known to be sensitive to this or similar local anesthetics. WARNINGS Caution should be exercised when administering Tigan® to children for the treatment of vomiting. Antiemetics are not recommended for treatment of uncomplicated vomiting in children and their use should be limited to prolonged vomiting of known etiology. There are two principal reasons for caution: 1. The extrapyramidal symptoms which can occur secondary to Tigan® may be confused with the central nervous system signs of an undiagnosed primary disease responsible for the vomiting, e.g., Reye’s syndrome or other encephalopathy. 2. It has been suspected that drugs with hepatotoxic potential, such as Tigan®, may unfavorably alter the course of Reye’s syndrome. Such drugs should therefore be avoided in children whose signs and symptoms (vomiting) could represent Reye’s syndrome. Tigan® may produce drowsiness. Patients should not operate motor vehicles or other dangerous machinery until their individual responses have been determined. Usage in Pregnancy: Trimethobenzamide hydrochloride was studied in reproduction experiments in rats and rabbits and no teratogenicity was suggested. The only effects observed were an increased percentage of embryonic resorptions or stillborn pups in rats administered 20 mg and 100 mg/kg and increased resorptions in rabbits receiving 100 mg/kg. In each study these adverse effects were attributed to one or two dams. The relevance to humans is not known. Since there is no adequate experience in pregnant or lactating women who have received this drug, safety in pregnancy or in nursing mothers has not been established. Usage with Alcohol: Concomitant use of alcohol with Tigan® may result in an adverse drug interaction. This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda PRECAUTIONS During the course of acute febrile illness, encephalitides, gastroenteritis, dehydration and electrolyte imbalance, especially in children and the elderly or debilitated, CNS reactions such as opisthotonos, convulsions, coma and extrapyramidal symptoms have been reported with and without use of Tigan® (trimethobenzamide hydrochloride) or other antiemetic agents. In such disorders caution should be exercised in administering Tigan®, particularly to patients who have recently received other CNS-acting agents (phenothiazines, barbiturates, belladonna derivatives). Primary emphasis should be directed toward the restoration of body fluids and electrolyte balance, the relief of fever and relief of the causative disease process. Overhydration should be avoided since it may result in cerebral edema. The antiemetic effects of Tigan® may render diagnosis more difficult in such conditions as appendicitis and obscure signs of toxicity due to overdosage of other drugs. ADVERSE REACTIONS There have been reports of hypersensitivity reactions and Parkinson-like symptoms. There have been instances of hypotension reported following parenteral administration to surgical patients. There have been reports of blood dyscrasias, blurring of vision, coma, convulsions, depression of mood, diarrhea, disorientation, dizziness, drowsiness, headache, jaundice, muscle cramps and opisthotonos. If these occur, the administration of the drug should be discontinued. Allergic-type skin reactions have been observed; therefore, the drug should be discontinued at the first sign of sensitization. While these symptoms will usually disappear spontaneously, symptomatic treatment may be indicated in some cases. DOSAGE AND ADMINISTRATION (See WARNINGS and PRECAUTIONS.) Dosage should be adjusted according to the indication for therapy, severity of symptoms and the response of the patient. CAPSULES, 300 mg This label may not be the latest approved by FDA.

Between 30 – 50% of a single dose in humans is excreted unchanged in the urine within 48 – 72 hours. The metabolic disposition of trimethobenzamide in humans is not known. Specifically, it is not known if active metabolites are generated in humans. Special Populations Age The clearance of trimethobenzamide is not known in patients with renal impairment. However, it may be advisable to consider reduction in the dosing of trimethobenzamide in elderly patients with renal impairment considering that a substantial amount of excretion and elimination of trimethobenzamide occurs via the kidney and that elderly patients may have various degrees of renal impairment.

Overhydration should be avoided since it may result in cerebral edema. The antiemetic effects of Tigan ® may render diagnosis more difficult in such conditions as appendicitis and obscure signs of toxicity due to overdosage of other drugs. General Adjustment of Dose in Renal Failure A substantial route of elimination of unchanged trimethobenzamide is via the kidney. Dosage adjustment should be considered in patients with reduced renal function including some elderly patients. (See CLINICAL PHARMACOLOGY and DOSAGE AND ADMINISTRATION). Geriatric Use Clinical studies of trimethobenzamide hydrochloride did not include sufficient numbers of patients aged 65 and over to determine whether they respond differently from younger patients. Although there are studies reported in the literature that included elderly patients >65 years old with younger patients, it is not known if there are differences in efficacy or safety parameters for elderly and non-elderly patients treated with trimethobenzamide. In general, dose selection for an elderly patient should be cautious, usually starting at the low end of the dosing range, reflecting the greater frequency of decreased hepatic, renal, or cardiac function, and of concomitant disease or other drug therapy. This drug is known to be substantially excreted by the kidney, and the risk of toxic reactions to this drug may be greater in patients with impaired renal function. Because elderly patients are more likely to have decreased renal function, care should be taken in dose selection, and it may be useful to monitor renal function. (See CLINICAL PHARMACOLOGY and DOSAGE AND ADMINISTRATION). ADVERSE REACTIONS There have been reports of hypersensitivity reactions and Parkinson-like symptoms. There have been instances of hypotension reported following parenteral administration to surgical patients. There have been reports of blood dyscrasias, blurring of vision, coma, convulsions, This label may not be the latest approved by FDA.

Geriatric Patients Dose adjustment such as reducing the total dose administered at each dosing or increasing the dosing interval should be considered in elderly patients with renal impairment (creatinine clearance ≤ 70 mL/min/1.73m2). Final dose adjustment should be based upon integration of clinical efficacy and safety considerations. (See CLINICAL PHARMACOLOGY and PRECAUTIONS). Patients with Renal Impairment In subjects with renal impairment (creatinine clearance ≤ 70 mL/min/1.73m2), dose adjustment such as reducing the total dose administered at each dosing or increasing the dosing interval should be considered. (See CLINICAL PHARMACOLOGY and DOSAGE AND ADMINISTRATION). INJECTABLE, 100 mg/mL (Not for use in pediatric patients) Usual Adult Dosage 2 mL (200 mg) t.i.d. or q.i.d. intramuscularly. NOTE: The injectable form is intended for intramuscular administration only; it is not recommended for intravenous use. Intramuscular administration may cause pain, stinging, burning, redness and swelling at the site of injection. Such effects may be minimized by deep injection into the upper outer quadrant of the gluteal region, and by avoiding the escape of solution along the route.

NDA 17-531/S-010 Tigan® (trimethobenzamide hydrochloride) Capsules/Suppositories/Injectable DESCRIPTION Chemically, trimethobenzamide HCl is N-[p-[2-(dimethylamino)ethoxy]benzyl]-3,4,5-trimethoxybenzamide monohydrochloride. It has a molecular weight of 424.93 and the following structural formula: (CH3)2N-CH2CH2O CH2NHC OCH3 OCH3 OCH3 O • HCl Capsules: Each 300-mg Tigan® capsule for oral use contains trimethobenzamide hydrochloride equivalent to 300 mg. The capsule has an opaque purple cap marked “Tigan” and an opaque purple body marked “M079”. Inactive Ingredients: D&C Red No. 28, FD&C Blue No. 1, lactose, magnesium stearate, starch and titanium dioxide. Suppositories (200 mg): Each suppository contains 200 mg trimethobenzamide hydrochloride and 2% benzocaine in a base compounded with polysorbate 80, white beeswax and propylene glycol monostearate. Suppositories, Pediatric (100 mg): Each suppository contains 100 mg trimethobenzamide hydrochloride and 2% benzocaine in a base compounded with polysorbate 80, white beeswax and propylene glycol monostearate. Ampuls: Each 2-mL ampul contains 200 mg trimethobenzamide hydrochloride compounded with 0.2% parabens (methyl and propyl) as preservatives, 1 mg sodium citrate and 0.4 mg citric acid as buffers and pH adjusted to approximately 5.0 with sodium hydroxide. Multi-Dose Vials: Each mL contains 100 mg trimethobenzamide hydrochloride compounded with 0.45% phenol as preservative, 0.5 mg sodium citrate and 0.2 mg citric acid as buffers and pH adjusted to approximately 5.0 with sodium hydroxide. CLINICAL PHARMACOLOGY Mechanism of Action The mechanism of action of Tigan® as determined in animals is obscure, but may involve the chemoreceptor trigger zone (CTZ), an area in the medulla oblongata through which emetic impulses are This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda NDA 17-531/S-010 conveyed to the vomiting center; direct impulses to the vomiting center apparently are not similarly inhibited. In dogs pretreated with trimethobenzamide HCl, the emetic response to apomorphine is inhibited, while little or no protection is afforded against emesis induced by intragastric copper sulfate. Pharmacokinetics The pharmacokinetics of trimethobenzamide have been studied in healthy adult subjects. Following administration of 200 mg (100 mg/mL) Tigan I.M. injection, the time to reach maximum plasma concentration (Tmax) was about half an hour, about 15 minutes longer for Tigan 300 mg oral capsule than an I.M. injection. A single dose of Tigan 300 mg oral capsule provided a plasma concentration profile of trimethobenzamide similar to Tigan 200 mg I.M. The relative bioavailability of the capsule formulation compared to the solution is 100%. The mean elimination half-life of trimethobenzamide is 7 to 9 hours. Special Populations Gender Systemic exposure to trimethobenzamide was similar between men (N=40) and women (N=28). Race Pharmacokinetics appeared to be similar for Caucasians (N=53) and African Americans (N=12). INDICATIONS Tigan® is indicated for the treatment of postoperative nausea and vomiting and for nausea associated with gastroenteritis. CONTRAINDICATIONS Use of the injectable form of Tigan® in children, the suppositories in premature or newborn infants, and use of any dosage form in patients with known hypersensitivity to trimethobenzamide are contraindicated. Since the suppositories contain benzocaine they should not be used in patients known to be sensitive to this or similar local anesthetics. WARNINGS Caution should be exercised when administering Tigan® to children for the treatment of vomiting. Antiemetics are not recommended for treatment of uncomplicated vomiting in children and their use should be limited to prolonged vomiting of known etiology. There are three principal reasons for caution: 1. The extrapyramidal symptoms which can occur secondary to Tigan® may be confused with the central nervous system signs of an undiagnosed primary disease responsible for the vomiting, e.g., Reye’s syndrome or other encephalopathy. This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda NDA 17-531/S-010 2. It has been suspected that drugs with hepatotoxic potential, such as Tigan®, may unfavorably alter the course of Reye’s syndrome. Such drugs should therefore be avoided in children whose signs and symptoms (vomiting) could represent Reye’s syndrome. Tigan® may produce drowsiness. Patients should not operate motor vehicles or other dangerous machinery until their individual responses have been determined. Usage in Pregnancy: Trimethobenzamide hydrochloride was studied in reproduction experiments in rats and rabbits and no teratogenicity was suggested. The only effects observed were an increased percentage of embryonic resorptions or stillborn pups in rats administered 20 mg and 100 mg/kg and increased resorptions in rabbits receiving 100 mg/kg. In each study these adverse effects were attributed to one or two dams. The relevance to humans is not known. Since there is no adequate experience in pregnant or lactating women who have received this drug, safety in pregnancy or in nursing mothers has not been established. Usage with Alcohol: Concomitant use of alcohol with Tigan® may result in an adverse drug interaction. PRECAUTIONS During the course of acute febrile illness, encephalitides, gastroenteritis, dehydration and electrolyte imbalance, especially in children and the elderly or debilitated, CNS reactions such as opisthotonos, convulsions, coma and extrapyramidal symptoms have been reported with and without use of Tigan® (trimethobenzamide hydrochloride) or other antiemetic agents. In such disorders caution should be exercised in administering Tigan®, particularly to patients who have recently received other CNS-acting agents (phenothiazines, barbiturates, belladonna derivatives). Primary emphasis should be directed toward the restoration of body fluids and electrolyte balance, the relief of fever and relief of the causative disease process. Overhydration should be avoided since it may result in cerebral edema. The antiemetic effects of Tigan® may render diagnosis more difficult in such conditions as appendicitis and obscure signs of toxicity due to overdosage of other drugs. ADVERSE REACTIONS There have been reports of hypersensitivity reactions and Parkinson-like symptoms. There have been instances of hypotension reported following parenteral administration to surgical patients. There have been reports of blood dyscrasias, blurring of vision, coma, convulsions, depression of mood, diarrhea, disorientation, dizziness, drowsiness, headache, jaundice, muscle cramps and opisthotonos. If these occur, the administration of the drug should be discontinued. Allergic- type skin reactions have been observed; therefore, the drug should be discontinued at the first sign of sensitization. While these symptoms will usually disappear spontaneously, symptomatic treatment may be indicated in some cases. This label may not be the latest approved by FDA.

Str uctural F ormula Diaßeta® (glyburide) Tablets USP 1.25, 2.5 and 5 mg DESCRIPTION Diaßeta® (glyburide) is an oral blood-glucose-lowering drug of the sulfonylurea class. It is a white, crystalline compound, formulated as tablets of 1.25 mg, 2.5 mg, and 5 mg strengths for oral administration. Diaßeta tablets USP contain the active ingredient glyburide and the following inactive ingredients: dibasic calcium phosphate USP, magnesium stearate NF, microcrystalline cellulose NF, sodium alginate NF, talc USP. Diaßeta 1.25 mg tablets USP also contain D&C Yellow #10 Aluminum Lake and FD&C Red #40 Aluminum Lake. Diaßeta 2.5 mg tablets USP also contain FD&C Red #40 Aluminum Lake. Diaßeta 5 mg tablets USP also contain D&C Yellow #10 Aluminum Lake, and FD&C Blue #1. Chemically, Diaßeta is identified as 1-[[p-[2-(5-Chloro-o-anisamido)ethyl]phenyl]sulfonyl]-3-cyclohexylurea. The CAS Registry Number is 10238-21-8. The structural formula is: The molecular weight is 493.99. The aqueous solubility of Diaßeta increases with pH as a result of salt formation. CLINICAL PHARMACOLOGY Diaßeta appears to lower the blood glucose acutely by stimulating the release of insulin from the pancreas, an effect dependent upon functioning beta cells in the pancreatic islets. The mechanism by which Diaßeta lowers blood glucose during long-term administration has not been clearly established. With chronic administration in Type II diabetic patients, the blood glucose lowering effect persists despite a gradual decline in the insulin secretory response to the drug. Extrapancreatic effects may play a part in the mechanism of action of oral sulfonylurea hypoglycemic drugs. In addition to its blood glucose lowering actions, Diaßeta produces a mild diuresis by enhancement of renal free water clearance. Clinical experience to date indicates an extremely low incidence of disulfiram-like reactions in patients while taking Diaßeta. Pharmacokinetics Single-dose studies with Diaßeta in normal subjects demonstrate significant absorption within one hour, peak drug levels at about four hours, and low but detectable levels at twenty-four hours. Mean serum levels of glyburide, as reflected by areas under the serum concentration-time curve, increase in proportion to corresponding increases in dose. Multiple-dose studies with Diaßeta in diabetic patients demonstrate drug level concentration-time curves similar to single- dose studies, indicating no build-up of drug in tissue depots. The decrease of glyburide in the serum of normal healthy individuals is biphasic, the terminal half-life being about 10 hours. In 1 single-dose studies in fasting normal subjects, the degree and duration of blood glucose lowering is proportional to the dose administered and to the area under the drug level concentration-time curve. The blood glucose lowering effect persists for 24 hours following single morning doses in non-fasting diabetic patients. Under conditions of repeated administration in diabetic patients, however, there is no reliable correlation between blood drug levels and fasting blood glucose levels. A one-year study of diabetic patients treated with Diaßeta showed no reliable correlation between administered dose and serum drug level. The major metabolite of Diaßeta is the 4-trans-hydroxy derivative. A second metabolite, the 3­ cis-hydroxy derivative, also occurs. These metabolites contribute no significant hypoglycemic action since they are only weakly active (1/400th and 1/40th, respectively, as glyburide) in rabbits. Diaßeta is excreted as metabolites in the bile and urine, approximately 50% by each route. This dual excretory pathway is qualitatively different from that of other sulfonylureas, which are excreted primarily in the urine. Sulfonylurea drugs are extensively bound to serum proteins. Displacement from protein binding sites by other drugs may lead to enhanced hypoglycemic action. In vitro, the protein binding exhibited by Diaßeta is predominantly non-ionic, whereas that of other sulfonylureas (chlorpropamide, tolbutamide, tolazamide) is predominantly ionic. Acidic drugs such as phenylbutazone, warfarin, and salicylates displace the ionic-binding sulfonylureas from serum proteins to a far greater extent than the non-ionic binding Diaßeta. It has not been shown that this difference in protein binding will result in fewer drug-drug interactions with Diaßeta in clinical use. INDICATIONS AND USAGE Diaßeta is indicated as an adjunct to diet and exercise to improve glycemic control in adults with type 2 diabetes mellitus. CONTRAINDICATIONS Diaßeta is contraindicated in patients: 1. With known hypersensitivity to the drug or any of its excipients. 2. With type 1 diabetes mellitus or diabetic ketoacidosis, with or without coma. These conditions should be treated with insulin. 3. Treated with bosentan. WARNINGS SPECIAL WARNING ON INCREASED RISK OF CARDIOVASCULAR MORTALITY The administration of oral hypoglycemic drugs has been reported to be associated with increased cardiovascular mortality as compared to treatment with diet alone or diet plus insulin. This warning is based on the study conducted by the University Group Diabetes Program (UGDP), a long-term prospective clinical trial designed to evaluate the effectiveness of glucose-lowering drugs in preventing or delaying vascular complications in 2 patients with non-insulin-dependent diabetes. The study involved 823 patients who were randomly assigned to one of four treatment groups (Diabetes 19 (supp. 2): 747-830, 1970). UGDP reported that patients treated for 5 to 8 years with diet plus a fixed dose of tolbutamide (1.5 grams per day) had a rate of cardiovascular mortality approximately 2­ 1/2 times that of patients treated with diet alone. A significant increase in total mortality was not observed, but the use of tolbutamide was discontinued based on the increase in cardiovascular mortality, thus limiting the opportunity for the study to show an increase in overall mortality. Despite controversy regarding the interpretation of these results, the findings of the UGDP study provide an adequate basis for this warning. The patient should be informed of the potential risks and advantages of Diaßeta and of alternative modes of therapy. Although only one drug in the sulfonylurea class (tolbutamide) was included in this study, it is prudent from a safety standpoint to consider that this warning may also apply to other oral hypoglycemic drugs in this class, in view of their close similarities in mode of action and chemical structure. Persons allergic to other sulfonamide derivatives may develop an allergic reaction to glyburide as well. PRECAUTIONS General Macrovascular Outcomes: There have been no clinical studies establishing conclusive evidence of macrovascular risk reduction with Diaßeta or any other anti-diabetic drug. Hypoglycemia: All sulfonylurea drugs are capable of producing severe hypoglycemia. Proper patient selection, dosage, and instructions are important to avoid hypoglycemic episodes. Severe renal or hepatic insufficiency may cause elevated blood levels of Diaßeta and the latter may also diminish gluconeogenic capacity, both of which increase the risk of serious, prolonged hypoglycemic reactions. Elderly, debilitated or malnourished patients, and those with adrenal or pituitary insufficiency are particularly susceptible to the hypoglycemic action of glucose- lowering drugs. Hypoglycemia may be difficult to recognize in patients with autonomic neuropathy, the elderly, and in people who are taking beta-adrenergic blocking drugs or other sympatholytic agents. Hypoglycemia is more likely to occur when caloric intake is deficient, after severe or prolonged exercise, when alcohol is ingested, or when more than one glucose-lowering drug is used. Loss of control of blood glucose: When a patient stabilized on any diabetic regimen is exposed to stress such as fever, trauma, infection, or surgery, a loss of control may occur. At such times, it may be necessary to discontinue Diaßeta and administer insulin. The effectiveness of any oral hypoglycemic drug, including Diaßeta, in lowering blood glucose to a desired level decreases in many patients over a period of time, which may be due to progression of the severity of the diabetes or to diminished responsiveness to the drug. This 3 phenomenon is known as secondary failure, to distinguish it from primary failure in which the drug is ineffective in an individual patient when first given. Hemolytic Anemia: Treatment of patients with glucose 6-phosphate dehydrogenase (G6PD) deficiency with sulfonylurea agents can lead to hemolytic anemia. Because Diaßeta belongs to the class of sulfonylurea agents, caution should be used in patients with G6PD deficiency and a non-sulfonylurea alternative should be considered. In postmarketing reports, hemolytic anemia has also been reported in patients who did not have known G6PD deficiency. Information for Patients Patients should be informed of the potential risks and advantages of Diaßeta and of alternative modes of therapy. They should also be informed about the importance of adherence to dietary instructions, of a regular exercise program, and of regular testing of blood glucose. The risks of hypoglycemia, its symptoms and treatment, and conditions that predispose to its development should be explained to patients and responsible family members. Primary and secondary failure should also be explained. Laboratory Tests Periodic fasting blood glucose measurements should be performed to monitor therapeutic response. A glycosylated hemoglobin determination should also be performed periodically. Drug Interactions The hypoglycemic action of sulfonylureas may be potentiated by certain drugs including nonsteroidal anti-inflammatory agents, ACE inhibitors, disopyramide, fluoxetine, clarithromycin, and other drugs that are highly protein bound, salicylates, sulfonamides, chloramphenicol, probenecid, monoamine oxidase inhibitors, and beta adrenergic blocking agents. When such drugs are administered to a patient receiving Diaßeta, the patient should be observed closely for hypoglycemia. When such drugs are withdrawn from a patient receiving Diaßeta, the patient should be observed closely for loss of control. A potential interaction between oral miconazole and oral hypoglycemic agents leading to severe hypoglycemia has been reported. Whether this interaction also occurs with the intravenous, topical or vaginal preparations of miconazole is not known. A possible interaction between glyburide and fluoroquinolone antibiotics has been reported resulting in a potentiation of the hypoglycemic action of glyburide. The mechanism for this interaction is not known. Possible interactions between glyburide and coumarin derivatives have been reported that may either potentiate or weaken the effects of coumarin derivatives. The mechanism of these interactions is not known. Rifampin may worsen glucose control of glyburide because rifampin can significantly induce metabolic isozymes of glyburide such as CYP2C9 and 3A4. 4 Certain drugs tend to produce hyperglycemia and may lead to loss of control. These drugs include the thiazides and other diuretics, corticosteroids, phenothiazines, thyroid products, estrogens, oral contraceptives, phenytoin, nicotinic acid, sympathomimetics, calcium channel blocking drugs, and isoniazid. When such drugs are administered to a patient receiving Diaßeta, the patient should be closely observed for loss of control. When such drugs are withdrawn from a patient receiving Diaßeta, the patient should be observed closely for hypoglycemia. An increased incidence of elevated liver enzymes was observed in patients receiving glyburide concomitantly with bosentan. Therefore this combination should not be used. (See CONTRAINDICATIONS.) Diaßeta may increase cyclosporine plasma concentration and potentially lead to its increased toxicity. Monitoring and dosage adjustment of cyclosporine are therefore recommended when both drugs are coadministered. Carcinogenesis, Mutagenesis, and Impairment of Fertility Diaßeta is non-mutagenic when studied in the Salmonella microsome test (Ames test) and in the DNA damage/alkaline elution assay. Studies in rats at doses up to 300 mg/kg/day for 18 months showed no carcinogenic effects. No drug related effects were noted in any of the criteria evaluated in the two year oncogenicity study of glyburide in mice. Pregnancy Teratogenic Effects: Pregnancy Category C Diaßeta has been shown to affect the maturation of the long bones (humerus and femur) in rat pups when given in doses 6250 times the maximum recommended human dose. These effects, which were seen during the period of lactation and not during organogenesis, are a shortening of the bones with effects to various structures of the long bones, especially in humerus and femur. There are no adequate and well-controlled studies in pregnant women. Because animal reproduction studies are not always predictive of human response, Diaßeta should be used during pregnancy only if the potential benefit justifies the risk to the fetus. Because recent information suggests that abnormal blood glucose levels during pregnancy are associated with a higher incidence of congenital abnormalities, many experts recommend that insulin be used during pregnancy to maintain blood glucose levels as close to normal as possible. Nonteratogenic Effects: Prolonged severe hypoglycemia (4 to 10 days) has been reported in neonates born to mothers who were receiving a sulfonylurea drug at the time of delivery. This has been reported more frequently with the use of agents with prolonged half-lives. If Diaßeta is used during pregnancy, it should be discontinued at least two weeks before the expected delivery date. Nursing Mothers Although it is not known whether Diaßeta is excreted in human milk, some sulfonylureas are known to be excreted in human milk. Because the potential for hypoglycemia in nursing infants 5 may exist, a decision should be made whether to discontinue nursing or to discontinue administering the drug, taking into account the importance of the drug to the mother. If Diaßeta is discontinued and if diet alone is inadequate for controlling blood glucose, insulin therapy should be considered. Pediatric Use Safety and effectiveness in pediatric patients have not been established. Geriatric Use In US clinical studies of glyburide, 1406 of 2897 patients were ≥60 years and 515 patients were ≥70 years. Differences in safety and efficacy were not determined between these patients and younger patients, but greater sensitivity of some older individuals cannot be ruled out. Elderly patients are particularly susceptible to hypoglycemic action of glucose-lowering drugs. Hypoglycemia may be difficult to recognize in the elderly (see PRECAUTIONS). The initial and maintenance dosing should be conservative to avoid hypoglycemic reactions. In three published studies of 20 to 51 subjects each, mixed results were seen in comparing the pharmacokinetics of glyburide in elderly versus younger subjects. However, observed pharmacodynamic differences indicate the necessity for dosage titration to a specified therapeutic response. This drug is known to be substantially excreted by the kidney, and the risk of toxic reactions to this drug may be greater in patients with impaired renal function. Because elderly patients are more likely to have decreased renal function, care should be taken in dose selection, and it may be useful to monitor renal function. In elderly, debilitated, or malnourished patients, or in patients with renal or hepatic insufficiency, the initial dosing, dose increments, and maintenance dosage should be conservative to avoid hypoglycemic reactions. Hypoglycemia may be difficult to recognize in the elderly and in people who are taking beta-adrenergic blocking drugs or other sympatholytic agents. (See PRECAUTIONS, General; and DOSAGE AND ADMINISTRATION.) ADVERSE REACTIONS Hypoglycemia: See PRECAUTIONS and OVERDOSAGE Sections. Gastrointestinal Reactions: Cholestatic jaundice and hepatitis may occur rarely which may progress to liver failure; Diaßeta should be discontinued if this occurs. Liver function abnormalities, including isolated transaminase elevations, have been reported. Gastrointestinal disturbances, e.g., nausea, epigastric fullness, and heartburn, are the most common reactions and occur in 1.8% of treated patients. They tend to be dose-related and may disappear when dosage is reduced. Dermatologic Reactions: Allergic skin reactions, e.g., pruritus, erythema, urticaria, and morbilliform or maculopapular eruptions, occur in 1.5% of treated patients. These may be 6 transient and may disappear despite continued use of Diaßeta; if skin reactions persist, the drug should be discontinued. Porphyria cutanea tarda and photosensitivity reactions have been reported with sulfonylureas. Hematologic Reactions: Leukopenia, agranulocytosis, thrombocytopenia, which occasionally may present as purpura, hemolytic anemia, aplastic anemia, and pancytopenia have been reported with sulfonylureas. Metabolic Reactions: Hepatic porphyria reactions have been reported with sulfonylureas; however, these have not been reported with Diaßeta. Disulfiram-like reactions have been reported very rarely with Diaßeta. Cases of hyponatremia have been reported with glyburide and all other sulfonylureas, most often in patients who are on other medications or have medical conditions known to cause hyponatremia or increase release of antidiuretic hormone. The syndrome of inappropriate antidiuretic hormone (SIADH) secretion has been reported with certain other sulfonylureas, and it has been suggested that these sulfonylureas may augment the peripheral (antidiuretic) action of ADH and/or increase release of ADH. Other Reactions: Changes in accommodation and/or blurred vision have been reported with glyburide and other sulfonylureas. These are thought to be related to fluctuation in glucose levels. In addition to dermatologic reactions, allergic reactions such as angioedema, arthralgia, myalgia and vasculitis have been reported. OVERDOSAGE Overdosage of sulfonylureas, including Diaßeta, can produce hypoglycemia. Mild hypoglycemic symptoms without loss of consciousness or neurologic findings should be treated aggressively with oral glucose and adjustments in drug dosage and/or meal patterns. Close monitoring should continue until the physician is assured that the patient is out of danger. Severe hypoglycemic reactions with coma, seizure, or other neurological impairment occur infrequently, but constitute medical emergencies requiring immediate hospitalization. If hypoglycemic coma is diagnosed or suspected, the patient should be given a rapid intravenous injection of concentrated (50%) glucose solution. This should be followed by a continuous infusion of a more dilute (10%) glucose solution at a rate that will maintain the blood glucose at a level above 100 mg/dL. Patients should be closely monitored for a minimum of 24 to 48 hours, since hypoglycemia may recur after apparent clinical recovery. DOSAGE AND ADMINISTRATION There is no fixed dosage regimen for the management of diabetes mellitus with Diaßeta or any other hypoglycemic agent. The patient’s fasting blood glucose must be measured periodically to determine the minimum effective dose for the patient; to detect primary failure, i.e., inadequate lowering of blood glucose at the maximum recommended dose of medication; and to detect secondary failure, i.e., loss of adequate blood glucose lowering response after an initial period of effectiveness. Periodic glycosylated hemoglobin determinations should be performed. 7 Short-term administration of Diaßeta may be sufficient during periods of transient loss of control in patients usually controlled well on diet. 1. Usual Starting Dose The usual starting dose of Diaßeta as initial therapy is 2.5 to 5 mg daily, administered with breakfast or the first main meal. Those patients who may be more sensitive to hypoglycemic drugs should be started at 1.25 mg daily. (See PRECAUTIONS Section for patients at increased risk). Failure to follow an appropriate dosage regimen may precipitate hypoglycemia. Patients who do not adhere to their prescribed dietary and drug regimen are more prone to exhibit unsatisfactory response to therapy. Transfer of patients from other oral antidiabetic regimens to Diaßeta should be done conservatively and the initial daily dose should be 2.5 to 5 mg. When transferring patients from oral hypoglycemic agents other than chlorpropamide, to Diaßeta, no transition period and no initial priming dose is necessary. When transferring patients from chlorpropamide, particular care should be exercised during the first two weeks because the prolonged retention of chlorpropamide in the body and subsequent overlapping drug effects may provoke hypoglycemia. Bioavailability studies have demonstrated that Glynase®* PresTab®* Tablets 3 mg are not bioequivalent to Diaßeta Tablets USP 5 mg. Therefore, these products are not substitutable and patients should be retitrated if transferred. Some Type II diabetic patients being treated with insulin may respond satisfactorily to Diaßeta. If the insulin dose is less than 20 units daily, substitution of Diaßeta 2.5 to 5 mg as a single daily dose may be tried. If the insulin dose is between 20 and 40 units daily, the patient may be placed directly on Diaßeta 5 mg daily as a single dose. If the insulin dose is more than 40 units daily, a transition period is required for conversion to Diaßeta. In these patients, insulin dosage is decreased by 50% and Diaßeta 5 mg daily is started. Please refer to Usual Maintenance Dose for further explanation. 2. Usual Maintenance Dose The usual maintenance dose is in the range of 1.25 to 20 mg daily, which may be given as a single dose or in divided doses (See Dosage Interval Section). Dosage increases should be made in increments of no more than 2.5 mg at weekly intervals based upon the patient’s blood glucose response. No exact dosage relationship exists between Diaßeta and the other oral hypoglycemic agents. Although patients may be transferred from the maximum dose of other sulfonylureas, the maximum starting dose of 5 mg of Diaßeta should be observed. A maintenance dose of 5 mg Diaßeta provides approximately the same degree of blood glucose control as 250 to 375 mg chlorpropamide, 250 to 375 mg tolazamide, 500 to 750 mg acetohexamide, or 1000 to 1500 mg tolbutamide. When transferring patients receiving more than 40 units of insulin daily, they may be started on a daily dose of Diaßeta 5 mg concomitantly with a 50% reduction in insulin 8 dose. Progressive withdrawal of insulin and increase of Diaßeta in increments of 1.25 to 2.5 mg every 2 to 10 days is then carried out. During this conversion period when both insulin and Diaßeta are being used, hypoglycemia may rarely occur. During insulin withdrawal, patients should self-test their blood for glucose and their urine for acetone at least 3 times daily and report results to their physician. Self-testing of urinary glucose is a less desirable alternative. The appearance of persistent acetonuria with glycosuria indicates that the patient is a Type I diabetic who requires insulin therapy. 3. Maximum Dose Daily doses of more than 20 mg are not recommended. 4. Dosage Interval Once-a-day therapy is usually satisfactory, based upon usual meal patterns and a 10 hour half-life of Diaßeta. Some patients, particularly those receiving more than 10 mg daily, may have a more satisfactory response with twice-a-day dosage. In elderly patients, debilitated or malnourished patients, and patients with impaired renal or hepatic function, the initial and maintenance dosing should be conservative to avoid hypoglycemic reactions.

NDA 17-531/S-010 Tigan® (trimethobenzamide hydrochloride) Capsules/Suppositories/Injectable DESCRIPTION Chemically, trimethobenzamide HCl is N-[p-[2-(dimethylamino)ethoxy]benzyl]-3,4,5- trimethoxybenzamide monohydrochloride. It has a molecular weight of 424.93 and the following structural formula: (CH3)2N-CH2CH2O CH2NHC OCH3 OCH3 OCH3 O • HCl Capsules: Each 300-mg Tigan® capsule for oral use contains trimethobenzamide hydrochloride equivalent to 300 mg. The capsule has an opaque purple cap marked “Tigan” and an opaque purple body marked “M079”. Inactive Ingredients: D&C Red No. 28, FD&C Blue No. 1, lactose, magnesium stearate, starch and titanium dioxide. Suppositories (200 mg): Each suppository contains 200 mg trimethobenzamide hydrochloride and 2% benzocaine in a base compounded with polysorbate 80, white beeswax and propylene glycol monostearate. Suppositories, Pediatric (100 mg): Each suppository contains 100 mg trimethobenzamide hydrochloride and 2% benzocaine in a base compounded with polysorbate 80, white beeswax and propylene glycol monostearate. Ampuls: Each 2-mL ampul contains 200 mg trimethobenzamide hydrochloride compounded with 0.2% This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda NDA 17-531/S-010 parabens (methyl and propyl) as preservatives, 1 mg sodium citrate and 0.4 mg citric acid as buffers and pH adjusted to approximately 5.0 with sodium hydroxide. Multi-Dose Vials: Each mL contains 100 mg trimethobenzamide hydrochloride compounded with 0.45% phenol as preservative, 0.5 mg sodium citrate and 0.2 mg citric acid as buffers and pH adjusted to approximately 5.0 with sodium hydroxide. CLINICAL PHARMACOLOGY Mechanism of Action The mechanism of action of Tigan® as determined in animals is obscure, but may involve the chemoreceptor trigger zone (CTZ), an area in the medulla oblongata through which emetic impulses are conveyed to the vomiting center; direct impulses to the vomiting center apparently are not similarly inhibited. In dogs pretreated with trimethobenzamide HCl, the emetic response to apomorphine is inhibited, while little or no protection is afforded against emesis induced by intragastric copper sulfate. Pharmacokinetics The pharmacokinetics of trimethobenzamide have been studied in healthy adult subjects. Following administration of 200 mg (100 mg/mL) Tigan I.M. injection, the time to reach maximum plasma concentration (Tmax) was about half an hour, about 15 minutes longer for Tigan 300 mg oral capsule than an I.M. injection. A single dose of Tigan 300 mg oral capsule provided a plasma concentration profile of trimethobenzamide similar to Tigan 200 mg I.M. The relative bioavailability of the capsule formulation compared to the solution is 100%. The mean elimination half-life of trimethobenzamide is 7 to 9 hours. Special Populations Gender Systemic exposure to trimethobenzamide was similar between men (N=40) and women (N=28). This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda NDA 17-531/S-010 Race Pharmacokinetics appeared to be similar for Caucasians (N=53) and African Americans (N=12). INDICATIONS Tigan® is indicated for the treatment of postoperative nausea and vomiting and for nausea associated with gastroenteritis. CONTRAINDICATIONS Use of the injectable form of Tigan® in children, the suppositories in premature or newborn infants, and use of any dosage form in patients with known hypersensitivity to trimethobenzamide are contraindicated. Since the suppositories contain benzocaine they should not be used in patients known to be sensitive to this or similar local anesthetics. WARNINGS Caution should be exercised when administering Tigan® to children for the treatment of vomiting. Antiemetics are not recommended for treatment of uncomplicated vomiting in children and their use should be limited to prolonged vomiting of known etiology. There are three principal reasons for caution: 1. The extrapyramidal symptoms which can occur secondary to Tigan® may be confused with the central nervous system signs of an undiagnosed primary disease responsible for the vomiting, e.g., Reye’s syndrome or other encephalopathy. 2. It has been suspected that drugs with hepatotoxic potential, such as Tigan®, may unfavorably alter the course of Reye’s syndrome. Such drugs should therefore be avoided in children whose signs and symptoms (vomiting) could represent Reye’s syndrome. Tigan® may produce drowsiness. Patients should not operate motor vehicles or other dangerous machinery until their individual responses have been determined. Usage in Pregnancy: Trimethobenzamide hydrochloride was studied in reproduction experiments in This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda NDA 17-531/S-010 rats and rabbits and no teratogenicity was suggested. The only effects observed were an increased percentage of embryonic resorptions or stillborn pups in rats administered 20 mg and 100 mg/kg and increased resorptions in rabbits receiving 100 mg/kg. In each study these adverse effects were attributed to one or two dams. The relevance to humans is not known. Since there is no adequate experience in pregnant or lactating women who have received this drug, safety in pregnancy or in nursing mothers has not been established. Usage with Alcohol: Concomitant use of alcohol with Tigan® may result in an adverse drug interaction. PRECAUTIONS During the course of acute febrile illness, encephalitides, gastroenteritis, dehydration and electrolyte imbalance, especially in children and the elderly or debilitated, CNS reactions such as opisthotonos, convulsions, coma and extrapyramidal symptoms have been reported with and without use of Tigan® (trimethobenzamide hydrochloride) or other antiemetic agents. In such disorders caution should be exercised in administering Tigan®, particularly to patients who have recently received other CNS- acting agents (phenothiazines, barbiturates, belladonna derivatives). Primary emphasis should be directed toward the restoration of body fluids and electrolyte balance, the relief of fever and relief of the causative disease process. Overhydration should be avoided since it may result in cerebral edema. The antiemetic effects of Tigan® may render diagnosis more difficult in such conditions as appendicitis and obscure signs of toxicity due to overdosage of other drugs. ADVERSE REACTIONS There have been reports of hypersensitivity reactions and Parkinson-like symptoms. There have been instances of hypotension reported following parenteral administration to surgical patients. There have been reports of blood dyscrasias, blurring of vision, coma, convulsions, depression of mood, diarrhea, disorientation, dizziness, drowsiness, headache, jaundice, muscle cramps and opisthotonos. If these This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda NDA 17-531/S-010 occur, the administration of the drug should be discontinued. Allergic-type skin reactions have been observed; therefore, the drug should be discontinued at the first sign of sensitization. While these symptoms will usually disappear spontaneously, symptomatic treatment may be indicated in some cases. DOSAGE AND ADMINISTRATION (See WARNINGS and PRECAUTIONS.) Dosage should be adjusted according to the indication for therapy, severity of symptoms and the response of the patient. CAPSULES, 300 mg Usual Adult Dosage One 300 mg capsule t.i.d. or q.i.d.

It has been suspected that drugs with hepatotoxic potential, such as Tigan®, may unfavorably alter the course of Reye’s syndrome. Such drugs should therefore be avoided in children whose signs and symptoms (vomiting) could represent Reye’s syndrome. Tigan® may produce drowsiness. Patients should not operate motor vehicles or other dangerous machinery until their individual responses have been determined. Usage in Pregnancy: Trimethobenzamide hydrochloride was studied in reproduction experiments in rats and rabbits and no teratogenicity was suggested. The only effects observed were an increased percentage of embryonic resorptions or stillborn pups in rats administered 20 mg and 100 mg/kg and increased resorptions in rabbits receiving 100 mg/kg. In each study these adverse effects were attributed to one or two dams. The relevance to humans is not known. Since there is no adequate experience in pregnant or lactating women who have received this drug, safety in pregnancy or in nursing mothers has not been established. Usage with Alcohol: Concomitant use of alcohol with Tigan® may result in an adverse drug interaction. PRECAUTIONS During the course of acute febrile illness, encephalitides, gastroenteritis, dehydration and electrolyte imbalance, especially in children and the elderly or debilitated, CNS reactions such as opisthotonos, convulsions, coma and extrapyramidal symptoms have been reported with and without use of Tigan® (trimethobenzamide hydrochloride) or other antiemetic agents. In such disorders caution should be exercised in administering Tigan®, particularly to patients who have recently received other CNS-acting agents (phenothiazines, barbiturates, belladonna derivatives). Primary emphasis should be directed toward the restoration of body fluids and electrolyte balance, the relief of fever and relief of the causative disease process. Overhydration should be avoided since it may result in cerebral edema. The antiemetic effects of Tigan® may render diagnosis more difficult in such conditions as appendicitis and obscure signs of toxicity due to overdosage of other drugs. General Adjustment of Dose in Renal Failure This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda NDA 17-531/S-012 Page 6 A substantial route of elimination of unchanged trimethobenzamide is via the kidney. Dosage adjustment should be considered in patients with reduced renal function including some elderly patients. (See CLINICAL PHARMACOLOGY and DOSAGE AND ADMINISTRATION). Geriatric Use Clinical studies of trimethobenzamide hydrochloride did not include sufficient numbers of patients aged 65 and over to determine whether they respond differently from younger patients. Although there are studies reported in the literature that included elderly patients > 65 years old with younger patients, it is not known if there are differences in efficacy or safety parameters for elderly and non-elderly patients treated with trimethobenzamide. In general, dose selection for an elderly patient should be cautious, usually starting at the low end of the dosing range, reflecting the greater frequency of decreased hepatic, renal, or cardiac function, and of concomitant disease or other drug therapy. This drug is known to be substantially excreted by the kidney, and the risk of toxic reactions to this drug may be greater in patients with impaired renal function. Because elderly patients are more likely to have decreased renal function, care should be taken in dose selection, and it may be useful to monitor renal function. (See CLINICAL PHARMACOLOGY and DOSAGE AND ADMINISTRATION). ADVERSE REACTIONS There have been reports of hypersensitivity reactions and Parkinson-like symptoms. There have been instances of hypotension reported following parenteral administration to surgical patients. There have been reports of blood dyscrasias, blurring of vision, coma, convulsions, depression of mood, diarrhea, disorientation, dizziness, drowsiness, headache, jaundice, muscle cramps and opisthotonos. If these occur, the administration of the drug should be discontinued. Allergic-type skin reactions have been observed; therefore, the drug should be discontinued at the first sign of sensitization. While these symptoms will usually disappear spontaneously, symptomatic treatment may be indicated in some cases. DOSAGE AND ADMINISTRATION (See WARNINGS and PRECAUTIONS.) Dosage should be adjusted according to the indication for therapy, severity of symptoms and the response of the patient. Geriatric Patients Dose adjustment such as reducing the total dose administered at each dosing or increasing the dosing interval should be considered in elderly patients with renal impairment (creatinine This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda NDA 17-531/S-012 Page 7 clearance ≤ 70 mL/min/1.73m²). Final dose adjustment should be based upon integration of clinical efficacy and safety considerations. (See CLINICAL PHARMACOLOGY and PRECAUTIONS). Patients with Renal Impairment In subjects with renal impairment (creatinine clearance ≤ 70 mL/min/1.73m²), dose adjustment such as reducing the total dose administered at each dosing or increasing the dosing interval should be considered.

Che mical Str ucture Diaßeta® (glyburide USP) Tablets 1.25, 2.5 and 5 mg DESCRIPTION Diaßeta® (glyburide USP) is an oral blood-glucose-lowering drug of the sulfonylurea class. It is a white, crystalline compound, formulated as tablets of 1.25 mg, 2.5 mg, and 5 mg strengths for oral administration. Diaßeta tablets contain the active ingredient glyburide and the following inactive ingredients: dibasic calcium phosphate USP, magnesium stearate NF, microcrystalline cellulose NF, sodium alginate NF, talc USP. Diaßeta 1.25 mg tablets also contain D&C Yellow #10 Aluminum Lake and FD&C Red #40 Aluminum Lake. Diaßeta 2.5 mg tablets also contain FD&C Red #40 Aluminum Lake. Diaßeta 5 mg tablets also contain D&C Yellow #10 Aluminum Lake, and FD&C Blue #1. Chemically, Diaßeta is identified as 1-[[p-[2-(5-Chloro-o­ anisamido)ethyl]phenyl]sulfonyl]-3-cyclohexylurea. The CAS Registry Number is 10238-21-8. The structural formula is: The molecular weight is 493.99. The aqueous solubility of Diaßeta increases with pH as a result of salt formation. CLINICAL PHARMACOLOGY Diaßeta appears to lower the blood glucose acutely by stimulating the release of insulin from the pancreas, an effect dependent upon functioning beta cells in the pancreatic islets. The mechanism by which Diaßeta lowers blood glucose during long-term administration has not been clearly established. With chronic administration in Type II diabetic patients, the blood glucose lowering effect persists despite a gradual decline in the insulin secretory response to the drug. Extrapancreatic effects may play a part in the mechanism of action of oral sulfonylurea hypoglycemic drugs. In addition to its blood glucose lowering actions, Diaßeta produces a mild diuresis by enhancement of renal free water clearance. Clinical experience to date indicates an extremely low incidence of disulfiram-like reactions in patients while taking Diaßeta. Pharmacokinetics Single-dose studies with Diaßeta in normal subjects demonstrate significant absorption within one hour, peak drug levels at about four hours, and low but detectable levels at twenty-four hours. Mean serum levels of glyburide, as reflected by areas under the serum concentration-time 1 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda curve, increase in proportion to corresponding increases in dose. Multiple-dose studies with Diaßeta in diabetic patients demonstrate drug level concentration-time curves similar to single- dose studies, indicating no build-up of drug in tissue depots. The decrease of glyburide in the serum of normal healthy individuals is biphasic, the terminal half-life being about 10 hours. In single-dose studies in fasting normal subjects, the degree and duration of blood glucose lowering is proportional to the dose administered and to the area under the drug level concentration-time curve. The blood glucose lowering effect persists for 24 hours following single morning doses in non-fasting diabetic patients. Under conditions of repeated administration in diabetic patients, however, there is no reliable correlation between blood drug levels and fasting blood glucose levels. A one-year study of diabetic patients treated with Diaßeta showed no reliable correlation between administered dose and serum drug level. The major metabolite of Diaßeta is the 4-trans-hydroxy derivative. A second metabolite, the 3­ cis-hydroxy derivative, also occurs. These metabolites contribute no significant hypoglycemic action since they are only weakly active (1/400th and 1/40th, respectively, as glyburide) in rabbits. Diaßeta is excreted as metabolites in the bile and urine, approximately 50% by each route. This dual excretory pathway is qualitatively different from that of other sulfonylureas, which are excreted primarily in the urine. Sulfonylurea drugs are extensively bound to serum proteins. Displacement from protein binding sites by other drugs may lead to enhanced hypoglycemic action. In vitro, the protein binding exhibited by Diaßeta is predominantly non-ionic, whereas that of other sulfonylureas (chlorpropamide, tolbutamide, tolazamide) is predominantly ionic. Acidic drugs such as phenylbutazone, warfarin, and salicylates displace the ionic-binding sulfonylureas from serum proteins to a far greater extent than the non-ionic binding Diaßeta. It has not been shown that this difference in protein binding will result in fewer drug-drug interactions with Diaßeta in clinical use. INDICATIONS AND USAGE Diaßeta is indicated as an adjunct to diet and exercise to improve glycemic control in adults with type 2 diabetes mellitus. CONTRAINDICATIONS Diaßeta is contraindicated in patients: 1. With known hypersensitivity to the drug or any of its excipients. 2. With diabetic ketoacidosis, with or without coma. This condition should be treated with insulin. 3. Treated with bosentan. WARNINGS SPECIAL WARNING ON INCREASED 2 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda RISK OF CARDIOVASCULAR MORTALITY The administration of oral hypoglycemic drugs has been reported to be associated with increased cardiovascular mortality as compared to treatment with diet alone or diet plus insulin. This warning is based on the study conducted by the University Group Diabetes Program (UGDP), a long-term prospective clinical trial designed to evaluate the effectiveness of glucose-lowering drugs in preventing or delaying vascular complications in patients with non-insulin-dependent diabetes. The study involved 823 patients who were randomly assigned to one of four treatment groups (Diabetes 19 (supp. 2): 747-830, 1970). UGDP reported that patients treated for 5 to 8 years with diet plus a fixed dose of tolbutamide (1.5 grams per day) had a rate of cardiovascular mortality approximately 2­ 1/2 times that of patients treated with diet alone. A significant increase in total mortality was not observed, but the use of tolbutamide was discontinued based on the increase in cardiovascular mortality, thus limiting the opportunity for the study to show an increase in overall mortality. Despite controversy regarding the interpretation of these results, the findings of the UGDP study provide an adequate basis for this warning. The patient should be informed of the potential risks and advantages of Diaßeta and of alternative modes of therapy. Although only one drug in the sulfonylurea class (tolbutamide) was included in this study, it is prudent from a safety standpoint to consider that this warning may also apply to other oral hypoglycemic drugs in this class, in view of their close similarities in mode of action and chemical structure. PRECAUTIONS General Macrovascular Outcomes: There have been no clinical studies establishing conclusive evidence of macrovascular risk reduction with Diaßeta or any other anti-diabetic drug. Hypoglycemia: All sulfonylurea drugs are capable of producing severe hypoglycemia. Proper patient selection, dosage, and instructions are important to avoid hypoglycemic episodes. Renal or hepatic insufficiency may cause elevated blood levels of Diaßeta and the latter may also diminish gluconeogenic capacity, both of which increase the risk of serious hypoglycemic reactions. Elderly, debilitated or malnourished patients, and those with adrenal or pituitary insufficiency are particularly susceptible to the hypoglycemic action of glucose-lowering drugs. Hypoglycemia may be difficult to recognize in the elderly, and in people who are taking beta- adrenergic blocking drugs or other sympatholytic agents. Hypoglycemia is more likely to occur when caloric intake is deficient, after severe or prolonged exercise, when alcohol is ingested, or when more than one glucose-lowering drug is used. Loss of control of blood glucose: When a patient stabilized on any diabetic regimen is exposed to stress such as fever, trauma, infection, or surgery, a loss of control may occur. At such times, it may be necessary to discontinue Diaßeta and administer insulin. 3 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda The effectiveness of any oral hypoglycemic drug, including Diaßeta, in lowering blood glucose to a desired level decreases in many patients over a period of time, which may be due to progression of the severity of the diabetes or to diminished responsiveness to the drug. This phenomenon is known as secondary failure, to distinguish it from primary failure in which the drug is ineffective in an individual patient when first given. Hemolytic Anemia: Treatment of patients with glucose 6-phosphate dehydrogenase (G6PD) deficiency with sulfonylurea agents can lead to hemolytic anemia. Because Diaßeta belongs to the class of sulfonylurea agents, caution should be used in patients with G6PD deficiency and a non-sulfonylurea alternative should be considered. In postmarketing reports, hemolytic anemia has also been reported in patients who did not have known G6PD deficiency. Information for Patients Patients should be informed of the potential risks and advantages of Diaßeta and of alternative modes of therapy. They should also be informed about the importance of adherence to dietary instructions, of a regular exercise program, and of regular testing of blood glucose. The risks of hypoglycemia, its symptoms and treatment, and conditions that predispose to its development should be explained to patients and responsible family members. Primary and secondary failure should also be explained. Laboratory Tests Periodic fasting blood glucose measurements should be performed to monitor therapeutic response. A glycosylated hemoglobin determination should also be performed periodically. Drug Interactions The hypoglycemic action of sulfonylureas may be potentiated by certain drugs including nonsteroidal anti-inflammatory agents and other drugs that are highly protein bound, salicylates, sulfonamides, chloramphenicol, probenecid, monoamine oxidase inhibitors, beta adrenergic blocking agents, and clarithromycin. When such drugs are administered to a patient receiving Diaßeta, the patient should be observed closely for hypoglycemia. When such drugs are withdrawn from a patient receiving Diaßeta, the patient should be observed closely for loss of control. A possible interaction between glyburide and fluoroquinolone antibiotics has been reported resulting in a potentiation of the hypoglycemic action of glyburide. The mechanism for this interaction is not known. Possible interactions between glyburide and coumarin derivatives have been reported that may either potentiate or weaken the effects of coumarin derivatives. The mechanism of these interactions is not known. 4 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda Certain drugs tend to produce hyperglycemia and may lead to loss of control. These drugs include the thiazides and other diuretics, corticosteroids, phenothiazines, thyroid products, estrogens, oral contraceptives, phenytoin, nicotinic acid, sympathomimetics, calcium channel blocking drugs, and isoniazid. When such drugs are administered to a patient receiving Diaßeta, the patient should be closely observed for loss of control. When such drugs are withdrawn from a patient receiving Diaßeta, the patient should be observed closely for hypoglycemia. A potential interaction between oral miconazole and oral hypoglycemic agents leading to severe hypoglycemia has been reported. Whether this interaction also occurs with the intravenous, topical or vaginal preparations of miconazole is not known. An increased incidence of elevated liver enzymes was observed in patients receiving glyburide concomitantly with bosentan. Therefore this combination should not be used. (See CONTRAINDICATIONS.) Diaßeta may increase cyclosporine plasma concentration and potentially lead to its increased toxicity. Monitoring and dosage adjustment of cyclosporine are therefore recommended when both drugs are coadministered. Carcinogenesis, Mutagenesis, and Impairment of Fertility Diaßeta is non-mutagenic when studied in the Salmonella microsome test (Ames test) and in the DNA damage/alkaline elution assay. Studies in rats at doses up to 300 mg/kg/day for 18 months showed no carcinogenic effects. No drug related effects were noted in any of the criteria evaluated in the two year oncogenicity study of glyburide in mice. Pregnancy Teratogenic Effects: Pregnancy Category C Diaßeta has been shown to affect the maturation of the long bones (humerus and femur) in rat pups when given in doses 6250 times the maximum recommended human dose. These effects, which were seen during the period of lactation and not during organogenesis, are a shortening of the bones with effects to various structures of the long bones, especially in humerus and femur. There are no adequate and well-controlled studies in pregnant women. Because animal reproduction studies are not always predictive of human response, Diaßeta should be used during pregnancy only if the potential benefit justifies the risk to the fetus. Because recent information suggests that abnormal blood glucose levels during pregnancy are associated with a higher incidence of congenital abnormalities, many experts recommend that insulin be used during pregnancy to maintain blood glucose levels as close to normal as possible. Nonteratogenic Effects: Prolonged severe hypoglycemia (4 to 10 days) has been reported in neonates born to mothers who were receiving a sulfonylurea drug at the time of delivery. This has been reported more frequently with the use of agents with prolonged half-lives. If Diaßeta is 5 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda used during pregnancy, it should be discontinued at least two weeks before the expected delivery date. Nursing Mothers Although it is not known whether Diaßeta is excreted in human milk, some sulfonylureas are known to be excreted in human milk. Because the potential for hypoglycemia in nursing infants may exist, a decision should be made whether to discontinue nursing or to discontinue administering the drug, taking into account the importance of the drug to the mother. If Diaßeta is discontinued and if diet alone is inadequate for controlling blood glucose, insulin therapy should be considered. Pediatric Use Safety and effectiveness in pediatric patients have not been established. Geriatric Use In US clinical studies of glyburide, 1406 of 2897 patients were ≥60 years and 515 patients were ≥70 years. Differences in safety and efficacy were not determined between these patients and younger patients, but greater sensitivity of some older individuals cannot be ruled out. Elderly patients are particularly susceptible to hypoglycemic action of glucose-lowering drugs. Hypoglycemia may be difficult to recognize in the elderly (see PRECAUTIONS). The initial and maintenance dosing should be conservative to avoid hypoglycemic reactions. In three published studies of 20 to 51 subjects each, mixed results were seen in comparing the pharmacokinetics of glyburide in elderly versus younger subjects. However, observed pharmacodynamic differences indicate the necessity for dosage titration to a specified therapeutic response. This drug is known to be substantially excreted by the kidney, and the risk of toxic reactions to this drug may be greater in patients with impaired renal function. Because elderly patients are more likely to have decreased renal function, care should be taken in dose selection, and it may be useful to monitor renal function. In elderly, debilitated, or malnourished patients, or in patients with renal or hepatic insufficiency, the initial dosing, dose increments, and maintenance dosage should be conservative to avoid hypoglycemic reactions. Hypoglycemia may be difficult to recognize in the elderly and in people who are taking beta-adrenergic blocking drugs or other sympatholytic agents. (See PRECAUTIONS, General; and DOSAGE AND ADMINISTRATION.) ADVERSE REACTIONS Hypoglycemia: See PRECAUTIONS and OVERDOSAGE Sections. 6 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda Gastrointestinal Reactions: Cholestatic jaundice and hepatitis may occur rarely; Diaßeta should be discontinued if this occurs. Liver function abnormalities, including isolated transaminase elevations, have been reported. Gastrointestinal disturbances, e.g., nausea, epigastric fullness, and heartburn, are the most common reactions and occur in 1.8% of treated patients. They tend to be dose-related and may disappear when dosage is reduced. Dermatologic Reactions: Allergic skin reactions, e.g., pruritus, erythema, urticaria, and morbilliform or maculopapular eruptions, occur in 1.5% of treated patients. These may be transient and may disappear despite continued use of Diaßeta; if skin reactions persist, the drug should be discontinued. Porphyria cutanea tarda and photosensitivity reactions have been reported with sulfonylureas. Hematologic Reactions: Leukopenia, agranulocytosis, thrombocytopenia, which occasionally may present as purpura, hemolytic anemia, aplastic anemia, and pancytopenia have been reported with sulfonylureas. Metabolic Reactions: Hepatic porphyria reactions have been reported with sulfonylureas; however, these have not been reported with Diaßeta. Disulfiram-like reactions have been reported very rarely with Diaßeta. Cases of hyponatremia have been reported with glyburide and all other sulfonylureas, most often in patients who are on other medications or have medical conditions known to cause hyponatremia or increase release of antidiuretic hormone. The syndrome of inappropriate antidiuretic hormone (SIADH) secretion has been reported with certain other sulfonylureas, and it has been suggested that these sulfonylureas may augment the peripheral (antidiuretic) action of ADH and/or increase release of ADH. Other Reactions: Changes in accommodation and/or blurred vision have been reported with glyburide and other sulfonylureas. These are thought to be related to fluctuation in glucose levels. In addition to dermatologic reactions, allergic reactions such as angioedema, arthralgia, myalgia and vasculitis have been reported. OVERDOSAGE Overdosage of sulfonylureas, including Diaßeta, can produce hypoglycemia. Mild hypoglycemic symptoms without loss of consciousness or neurologic findings should be treated aggressively with oral glucose and adjustments in drug dosage and/or meal patterns. Close monitoring should continue until the physician is assured that the patient is out of danger. Severe hypoglycemic reactions with coma, seizure, or other neurological impairment occur infrequently, but constitute medical emergencies requiring immediate hospitalization. If hypoglycemic coma is diagnosed or suspected, the patient should be given a rapid intravenous injection of concentrated (50%) glucose solution. This should be followed by a continuous infusion of a more dilute (10%) glucose solution at a rate that will maintain the blood glucose at a level above 100 mg/dL. Patients should be closely monitored for a minimum of 24 to 48 hours, since hypoglycemia may recur after apparent clinical recovery. 7 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda DOSAGE AND ADMINISTRATION There is no fixed dosage regimen for the management of diabetes mellitus with Diaßeta or any other hypoglycemic agent. The patient’s fasting blood glucose must be measured periodically to determine the minimum effective dose for the patient; to detect primary failure, i.e., inadequate lowering of blood glucose at the maximum recommended dose of medication; and to detect secondary failure, i.e., loss of adequate blood glucose lowering response after an initial period of effectiveness. Periodic glycosylated hemoglobin determinations should be performed. Short-term administration of Diaßeta may be sufficient during periods of transient loss of control in patients usually controlled well on diet. 1. Usual Starting Dose The usual starting dose of Diaßeta as initial therapy is 2.5 to 5 mg daily, administered with breakfast or the first main meal. Those patients who may be more sensitive to hypoglycemic drugs should be started at 1.25 mg daily. (See PRECAUTIONS Section for patients at increased risk). Failure to follow an appropriate dosage regimen may precipitate hypoglycemia. Patients who do not adhere to their prescribed dietary and drug regimen are more prone to exhibit unsatisfactory response to therapy. Transfer of patients from other oral antidiabetic regimens to Diaßeta should be done conservatively and the initial daily dose should be 2.5 to 5 mg. When transferring patients from oral hypoglycemic agents other than chlorpropamide, to Diaßeta, no transition period and no initial priming dose is necessary. When transferring patients from chlorpropamide, particular care should be exercised during the first two weeks because the prolonged retention of chlorpropamide in the body and subsequent overlapping drug effects may provoke hypoglycemia. Bioavailability studies have demonstrated that Glynase®* PresTab®* Tablets 3 mg are not bioequivalent to Diaßeta Tablets 5 mg. Therefore, these products are not substitutable and patients should be retitrated if transferred. Some Type II diabetic patients being treated with insulin may respond satisfactorily to Diaßeta. If the insulin dose is less than 20 units daily, substitution of Diaßeta 2.5 to 5 mg as a single daily dose may be tried. If the insulin dose is between 20 and 40 units daily, the patient may be placed directly on Diaßeta 5 mg daily as a single dose. If the insulin dose is more than 40 units daily, a transition period is required for conversion to Diaßeta. In these patients, insulin dosage is decreased by 50% and Diaßeta 5 mg daily is started. Please refer to Usual Maintenance Dose for further explanation. 2. Usual Maintenance Dose The usual maintenance dose is in the range of 1.25 to 20 mg daily, which may be given as a single dose or in divided doses (See Dosage Interval Section). Dosage increases should 8 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda be made in increments of no more than 2.5 mg at weekly intervals based upon the patient’s blood glucose response. No exact dosage relationship exists between Diaßeta and the other oral hypoglycemic agents. Although patients may be transferred from the maximum dose of other sulfonylureas, the maximum starting dose of 5 mg of Diaßeta should be observed. A maintenance dose of 5 mg Diaßeta provides approximately the same degree of blood glucose control as 250 to 375 mg chlorpropamide, 250 to 375 mg tolazamide, 500 to 750 mg acetohexamide, or 1000 to 1500 mg tolbutamide. When transferring patients receiving more than 40 units of insulin daily, they may be started on a daily dose of Diaßeta 5 mg concomitantly with a 50% reduction in insulin dose. Progressive withdrawal of insulin and increase of Diaßeta in increments of 1.25 to 2.5 mg every 2 to 10 days is then carried out. During this conversion period when both insulin and Diaßeta are being used, hypoglycemia may rarely occur. During insulin withdrawal, patients should self-test their blood for glucose and their urine for acetone at least 3 times daily and report results to their physician. Self-testing of urinary glucose is a less desirable alternative. The appearance of persistent acetonuria with glycosuria indicates that the patient is a Type I diabetic who requires insulin therapy. 3. Maximum Dose Daily doses of more than 20 mg are not recommended. 4. Dosage Interval Once-a-day therapy is usually satisfactory, based upon usual meal patterns and a 10 hour half-life of Diaßeta. Some patients, particularly those receiving more than 10 mg daily, may have a more satisfactory response with twice-a-day dosage. In elderly patients, debilitated or malnourished patients, and patients with impaired renal or hepatic function, the initial and maintenance dosing should be conservative to avoid hypoglycemic reactions.

For current labeling information, please visit https://www.fda.gov/drugsatfda serum of normal healthy individuals is biphasic, the terminal half-life being about 10 hours. In single-dose studies in fasting normal subjects, the degree and duration of blood glucose lowering is proportional to the dose administered and to the area under the drug level concentration-time curve. The blood glucose lowering effect persists for 24 hours following single morning doses in non-fasting diabetic patients. Under conditions of repeated administration in diabetic patients, however, there is no reliable correlation between blood drug levels and fasting blood glucose levels. A one-year study of diabetic patients treated with Diaßeta showed no reliable correlation between administered dose and serum drug level. The major metabolite of Diaßeta is the 4-trans-hydroxy derivative. A second metabolite, the 3­ cis-hydroxy derivative, also occurs. These metabolites contribute no significant hypoglycemic action since they are only weakly active (1/400th and 1/40th, respectively, as glyburide) in rabbits. Diaßeta is excreted as metabolites in the bile and urine, approximately 50% by each route. This dual excretory pathway is qualitatively different from that of other sulfonylureas, which are excreted primarily in the urine. Sulfonylurea drugs are extensively bound to serum proteins. Displacement from protein binding sites by other drugs may lead to enhanced hypoglycemic action. In vitro, the protein binding exhibited by Diaßeta is predominantly non-ionic, whereas that of other sulfonylureas (chlorpropamide, tolbutamide, tolazamide) is predominantly ionic. Acidic drugs such as phenylbutazone, warfarin, and salicylates displace the ionic-binding sulfonylureas from serum proteins to a far greater extent than the non-ionic binding Diaßeta. It has not been shown that this difference in protein binding will result in fewer drug-drug interactions with Diaßeta in clinical use. INDICATIONS AND USAGE Diaßeta is indicated as an adjunct to diet and exercise to improve glycemic control in adults with type 2 diabetes mellitus. CONTRAINDICATIONS Diaßeta is contraindicated in patients: 1. With known hypersensitivity to the drug or any of its excipients. 2. With type 1 diabetes mellitus or diabetic ketoacidosis, with or without coma. These conditions should be treated with insulin. 3. Treated with bosentan. WARNINGS SPECIAL WARNING ON INCREASED RISK OF CARDIOVASCULAR MORTALITY The administration of oral hypoglycemic drugs has been reported to be associated with increased cardiovascular mortality as compared to treatment with diet alone or diet plus insulin. This warning is based on the study conducted by the University Group Diabetes Program (UGDP), a long-term prospective clinical trial designed to evaluate the effectiveness of glucose-lowering drugs in preventing or delaying vascular complications in 2 Reference ID: 3389297 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda patients with non-insulin-dependent diabetes. The study involved 823 patients who were randomly assigned to one of four treatment groups (Diabetes 19 (supp. 2): 747-830, 1970). UGDP reported that patients treated for 5 to 8 years with diet plus a fixed dose of tolbutamide (1.5 grams per day) had a rate of cardiovascular mortality approximately 2­ 1/2 times that of patients treated with diet alone. A significant increase in total mortality was not observed, but the use of tolbutamide was discontinued based on the increase in cardiovascular mortality, thus limiting the opportunity for the study to show an increase in overall mortality. Despite controversy regarding the interpretation of these results, the findings of the UGDP study provide an adequate basis for this warning. The patient should be informed of the potential risks and advantages of Diaßeta and of alternative modes of therapy. Although only one drug in the sulfonylurea class (tolbutamide) was included in this study, it is prudent from a safety standpoint to consider that this warning may also apply to other oral hypoglycemic drugs in this class, in view of their close similarities in mode of action and chemical structure. Persons allergic to other sulfonamide derivatives may develop an allergic reaction to glyburide as well. PRECAUTIONS General Macrovascular Outcomes: There have been no clinical studies establishing conclusive evidence of macrovascular risk reduction with Diaßeta or any other anti-diabetic drug. Hypoglycemia: All sulfonylurea drugs are capable of producing severe hypoglycemia. Proper patient selection, dosage, and instructions are important to avoid hypoglycemic episodes. Severe renal or hepatic insufficiency may cause elevated blood levels of Diaßeta and the latter may also diminish gluconeogenic capacity, both of which increase the risk of serious, prolonged hypoglycemic reactions. Elderly, debilitated or malnourished patients, and those with adrenal or pituitary insufficiency are particularly susceptible to the hypoglycemic action of glucose- lowering drugs. Hypoglycemia may be difficult to recognize in patients with autonomic neuropathy, the elderly, and in people who are taking beta-adrenergic blocking drugs or other sympatholytic agents. Hypoglycemia is more likely to occur when caloric intake is deficient, after severe or prolonged exercise, when alcohol is ingested, or when more than one glucose-lowering drug is used. Loss of control of blood glucose: When a patient stabilized on any diabetic regimen is exposed to stress such as fever, trauma, infection, or surgery, a loss of control may occur. At such times, it may be necessary to discontinue Diaßeta and administer insulin. The effectiveness of any oral hypoglycemic drug, including Diaßeta, in lowering blood glucose to a desired level decreases in many patients over a period of time, which may be due to progression of the severity of the diabetes or to diminished responsiveness to the drug. This 3 Reference ID: 3389297 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda phenomenon is known as secondary failure, to distinguish it from primary failure in which the drug is ineffective in an individual patient when first given. Hemolytic Anemia: Treatment of patients with glucose 6-phosphate dehydrogenase (G6PD) deficiency with sulfonylurea agents can lead to hemolytic anemia. Because Diaßeta belongs to the class of sulfonylurea agents, caution should be used in patients with G6PD deficiency and a non-sulfonylurea alternative should be considered. In postmarketing reports, hemolytic anemia has also been reported in patients who did not have known G6PD deficiency. Information for Patients Patients should be informed of the potential risks and advantages of Diaßeta and of alternative modes of therapy. They should also be informed about the importance of adherence to dietary instructions, of a regular exercise program, and of regular testing of blood glucose. The risks of hypoglycemia, its symptoms and treatment, and conditions that predispose to its development should be explained to patients and responsible family members. Primary and secondary failure should also be explained. Laboratory Tests Periodic fasting blood glucose measurements should be performed to monitor therapeutic response. A glycosylated hemoglobin determination should also be performed periodically. Drug Interactions The hypoglycemic action of sulfonylureas may be potentiated by certain drugs including nonsteroidal anti-inflammatory agents, ACE inhibitors, disopyramide, fluoxetine, clarithromycin, and other drugs that are highly protein bound, salicylates, sulfonamides, chloramphenicol, probenecid, monoamine oxidase inhibitors, and beta adrenergic blocking agents. When such drugs are administered to a patient receiving Diaßeta, the patient should be observed closely for hypoglycemia. When such drugs are withdrawn from a patient receiving Diaßeta, the patient should be observed closely for loss of control. An increased incidence of elevated liver enzymes was observed in patients receiving glyburide concomitantly with bosentan. Therefore concomitant administration of Diaßeta and bosentan is contraindicated (see CONTRAINDICATIONS). A potential interaction between oral miconazole and oral hypoglycemic agents leading to severe hypoglycemia has been reported. Whether this interaction also occurs with the intravenous, topical or vaginal preparations of miconazole is not known. A possible interaction between glyburide and fluoroquinolone antibiotics has been reported resulting in a potentiation of the hypoglycemic action of glyburide. The mechanism for this interaction is not known. Possible interactions between glyburide and coumarin derivatives have been reported that may either potentiate or weaken the effects of coumarin derivatives. The mechanism of these interactions is not known. 4 Reference ID: 3389297 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda Rifampin may worsen glucose control of glyburide because rifampin can significantly induce metabolic isozymes of glyburide such as CYP2C9 and 3A4. Certain drugs tend to produce hyperglycemia and may lead to loss of control. These drugs include the thiazides and other diuretics, corticosteroids, phenothiazines, thyroid products, estrogens, oral contraceptives, phenytoin, nicotinic acid, sympathomimetics, calcium channel blocking drugs, and isoniazid. When such drugs are administered to a patient receiving Diaßeta, the patient should be closely observed for loss of control. When such drugs are withdrawn from a patient receiving Diaßeta, the patient should be observed closely for hypoglycemia. Diaßeta may increase cyclosporine plasma concentration and potentially lead to its increased toxicity. Monitoring and dosage adjustment of cyclosporine are therefore recommended when both drugs are coadministered. Colesevelam: Concomitant administration of colesevelam and glyburide resulted in reductions in glyburide AUC and Cmax of 32% and 47%, respectively. When glyburide was administered 1 hour before colesevelam, the reductions in glyburide AUC and Cmax were 20% and 15%, respectively, and not significantly changed (-7% and 4%, respectively) when administered 4 hours before colesevelam. Therefore, glyburide should be administered at least 4 hours prior to colesevelam. Glyburide is mainly metabolized by CYP 2C9 and to a lesser extent by CYP 3A4. There is a potential for drug-drug interaction when glyburide is coadministered with inducers or inhibitors of CYP 2C9, which should be taken into account when considering concomitant therapy. Carcinogenesis, Mutagenesis, and Impairment of Fertility Diaßeta is non-mutagenic when studied in the Salmonella microsome test (Ames test) and in the DNA damage/alkaline elution assay. Studies in rats at doses up to 300 mg/kg/day for 18 months showed no carcinogenic effects. No drug related effects were noted in any of the criteria evaluated in the two year oncogenicity study of glyburide in mice. Pregnancy Teratogenic Effects: Pregnancy Category C Diaßeta has been shown to affect the maturation of the long bones (humerus and femur) in rat pups when given in doses 6250 times the maximum recommended human dose. These effects, which were seen during the period of lactation and not during organogenesis, are a shortening of the bones with effects to various structures of the long bones, especially in humerus and femur. There are no adequate and well-controlled studies in pregnant women. Because animal reproduction studies are not always predictive of human response, Diaßeta should be used during pregnancy only if the potential benefit justifies the risk to the fetus. Because recent information suggests that abnormal blood glucose levels during pregnancy are associated with a higher 5 Reference ID: 3389297 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda incidence of congenital abnormalities, many experts recommend that insulin be used during pregnancy to maintain blood glucose levels as close to normal as possible. Nonteratogenic Effects: Prolonged severe hypoglycemia (4 to 10 days) has been reported in neonates born to mothers who were receiving a sulfonylurea drug at the time of delivery. This has been reported more frequently with the use of agents with prolonged half-lives. If Diaßeta is used during pregnancy, it should be discontinued at least two weeks before the expected delivery date. Nursing Mothers Although it is not known whether Diaßeta is excreted in human milk, some sulfonylureas are known to be excreted in human milk. Because the potential for hypoglycemia in nursing infants may exist, a decision should be made whether to discontinue nursing or to discontinue administering the drug, taking into account the importance of the drug to the mother. If Diaßeta is discontinued and if diet alone is inadequate for controlling blood glucose, insulin therapy should be considered. Pediatric Use Safety and effectiveness in pediatric patients have not been established. Geriatric Use In US clinical studies of glyburide, 1406 of 2897 patients were ≥60 years and 515 patients were ≥70 years. Differences in safety and efficacy were not determined between these patients and younger patients, but greater sensitivity of some older individuals cannot be ruled out. Elderly patients are particularly susceptible to hypoglycemic action of glucose-lowering drugs. Hypoglycemia may be difficult to recognize in the elderly (see PRECAUTIONS). The initial and maintenance dosing should be conservative to avoid hypoglycemic reactions. In three published studies of 20 to 51 subjects each, mixed results were seen in comparing the pharmacokinetics of glyburide in elderly versus younger subjects. However, observed pharmacodynamic differences indicate the necessity for dosage titration to a specified therapeutic response. This drug is known to be substantially excreted by the kidney, and the risk of toxic reactions to this drug may be greater in patients with impaired renal function. Because elderly patients are more likely to have decreased renal function, care should be taken in dose selection, and it may be useful to monitor renal function. In elderly, debilitated, or malnourished patients, or in patients with renal or hepatic insufficiency, the initial dosing, dose increments, and maintenance dosage should be conservative to avoid hypoglycemic reactions. Hypoglycemia may be difficult to recognize in the elderly and in people who are taking beta-adrenergic blocking drugs or other sympatholytic agents. (See PRECAUTIONS, General; and DOSAGE AND ADMINISTRATION.) 6 Reference ID: 3389297 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda ADVERSE REACTIONS Hypoglycemia: See PRECAUTIONS and OVERDOSAGE Sections. Gastrointestinal Reactions: Cholestatic jaundice and hepatitis may occur rarely which may progress to liver failure; Diaßeta should be discontinued if this occurs. Liver function abnormalities, including isolated transaminase elevations, have been reported. Gastrointestinal disturbances, e.g., nausea, epigastric fullness, and heartburn, are the most common reactions and occur in 1.8% of treated patients. They tend to be dose-related and may disappear when dosage is reduced. Dermatologic Reactions: Allergic skin reactions, e.g., pruritus, erythema, urticaria, and morbilliform or maculopapular eruptions, occur in 1.5% of treated patients. These may be transient and may disappear despite continued use of Diaßeta; if skin reactions persist, the drug should be discontinued. Porphyria cutanea tarda and photosensitivity reactions have been reported with sulfonylureas. Hematologic Reactions: Leukopenia, agranulocytosis, thrombocytopenia, which occasionally may present as purpura, hemolytic anemia, aplastic anemia, and pancytopenia have been reported with sulfonylureas. Metabolic Reactions: Hepatic porphyria reactions have been reported with sulfonylureas; however, these have not been reported with Diaßeta. Disulfiram-like reactions have been reported very rarely with Diaßeta. Cases of hyponatremia have been reported with glyburide and all other sulfonylureas, most often in patients who are on other medications or have medical conditions known to cause hyponatremia or increase release of antidiuretic hormone. The syndrome of inappropriate antidiuretic hormone (SIADH) secretion has been reported with certain other sulfonylureas, and it has been suggested that these sulfonylureas may augment the peripheral (antidiuretic) action of ADH and/or increase release of ADH. Other Reactions: Changes in accommodation and/or blurred vision have been reported with glyburide and other sulfonylureas. These are thought to be related to fluctuation in glucose levels. In addition to dermatologic reactions, allergic reactions such as angioedema, arthralgia, myalgia and vasculitis have been reported. OVERDOSAGE Overdosage of sulfonylureas, including Diaßeta, can produce hypoglycemia. Mild hypoglycemic symptoms without loss of consciousness or neurologic findings should be treated aggressively with oral glucose and adjustments in drug dosage and/or meal patterns. Close monitoring should continue until the physician is assured that the patient is out of danger. Severe hypoglycemic reactions with coma, seizure, or other neurological impairment occur infrequently, but constitute medical emergencies requiring immediate hospitalization. If hypoglycemic coma is diagnosed or suspected, the patient should be given a rapid intravenous injection of concentrated (50%) glucose solution. This should be followed by a continuous infusion of a more dilute (10%) 7 Reference ID: 3389297 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda glucose solution at a rate that will maintain the blood glucose at a level above 100 mg/dL. Patients should be closely monitored for a minimum of 24 to 48 hours, since hypoglycemia may recur after apparent clinical recovery. DOSAGE AND ADMINISTRATION There is no fixed dosage regimen for the management of diabetes mellitus with Diaßeta or any other hypoglycemic agent. The patient’s fasting blood glucose must be measured periodically to determine the minimum effective dose for the patient; to detect primary failure, i.e., inadequate lowering of blood glucose at the maximum recommended dose of medication; and to detect secondary failure, i.e., loss of adequate blood glucose lowering response after an initial period of effectiveness. Periodic glycosylated hemoglobin determinations should be performed. Short-term administration of Diaßeta may be sufficient during periods of transient loss of control in patients usually controlled well on diet. 1. Usual Starting Dose The usual starting dose of Diaßeta as initial therapy is 2.5 to 5 mg daily, administered with breakfast or the first main meal. Those patients who may be more sensitive to hypoglycemic drugs should be started at 1.25 mg daily. (See PRECAUTIONS Section for patients at increased risk). Failure to follow an appropriate dosage regimen may precipitate hypoglycemia. Patients who do not adhere to their prescribed dietary and drug regimen are more prone to exhibit unsatisfactory response to therapy. Transfer of patients from other oral antidiabetic regimens to Diaßeta should be done conservatively and the initial daily dose should be 2.5 to 5 mg. When transferring patients from oral hypoglycemic agents other than chlorpropamide, to Diaßeta, no transition period and no initial priming dose is necessary. When transferring patients from chlorpropamide, particular care should be exercised during the first two weeks because the prolonged retention of chlorpropamide in the body and subsequent overlapping drug effects may provoke hypoglycemia. Bioavailability studies have demonstrated that Glynase®* PresTab®* Tablets 3 mg are not bioequivalent to Diaßeta Tablets USP 5 mg. Therefore, these products are not substitutable and patients should be retitrated if transferred. Some Type II diabetic patients being treated with insulin may respond satisfactorily to Diaßeta. If the insulin dose is less than 20 units daily, substitution of Diaßeta 2.5 to 5 mg as a single daily dose may be tried. If the insulin dose is between 20 and 40 units daily, the patient may be placed directly on Diaßeta 5 mg daily as a single dose. If the insulin dose is more than 40 units daily, a transition period is required for conversion to Diaßeta. In these patients, insulin dosage is decreased by 50% and Diaßeta 5 mg daily is started. Please refer to Usual Maintenance Dose for further explanation. When colesevelam is coadministered with glyburide, maximum plasma concentration and total exposure to glyburide is reduced. Therefore, Diaßeta should be administered at least 4 hours prior to colesevelam. 8 Reference ID: 3389297 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda 2. Usual Maintenance Dose The usual maintenance dose is in the range of 1.25 to 20 mg daily, which may be given as a single dose or in divided doses (See Dosage Interval Section). Dosage increases should be made in increments of no more than 2.5 mg at weekly intervals based upon the patient’s blood glucose response. No exact dosage relationship exists between Diaßeta and the other oral hypoglycemic agents. Although patients may be transferred from the maximum dose of other sulfonylureas, the maximum starting dose of 5 mg of Diaßeta should be observed. A maintenance dose of 5 mg Diaßeta provides approximately the same degree of blood glucose control as 250 to 375 mg chlorpropamide, 250 to 375 mg tolazamide, 500 to 750 mg acetohexamide, or 1000 to 1500 mg tolbutamide. When transferring patients receiving more than 40 units of insulin daily, they may be started on a daily dose of Diaßeta 5 mg concomitantly with a 50% reduction in insulin dose. Progressive withdrawal of insulin and increase of Diaßeta in increments of 1.25 to 2.5 mg every 2 to 10 days is then carried out. During this conversion period when both insulin and Diaßeta are being used, hypoglycemia may rarely occur. During insulin withdrawal, patients should self-test their blood for glucose and their urine for acetone at least 3 times daily and report results to their physician. Self-testing of urinary glucose is a less desirable alternative. The appearance of persistent acetonuria with glycosuria indicates that the patient is a Type I diabetic who requires insulin therapy. 3. Maximum Dose Daily doses of more than 20 mg are not recommended. 4. Dosage Interval Once-a-day therapy is usually satisfactory, based upon usual meal patterns and a 10 hour half-life of Diaßeta. Some patients, particularly those receiving more than 10 mg daily, may have a more satisfactory response with twice-a-day dosage. In elderly patients, debilitated or malnourished patients, and patients with impaired renal or hepatic function, the initial and maintenance dosing should be conservative to avoid hypoglycemic reactions.

SCH 11460 SECTION 2 DIPROSONE CREAM PAGE 1 DRAFT LABELING XXXXXXXX PRODUCT INFORMATION DIPROSONE® brand of betamethasone dipropionate Cream, USP 0.05% (potency expressed as betamethasone) For Dermatologic Use Only - Not for Ophthalmic Use DESCRIPTION DIPROSONE Cream contains betamethasone dipropionate, USP, a synthetic adrenocorticosteroid, for dermatologic use. Betamethasone, an analog of prednisolone, has high corticosteroid activity and slight mineralocorticoid activity. Betamethasone dipropionate is the 17, 21-dipropionate ester of betamethasone. Chemically, betamethasone dipropionate is 9-Fluoro-11β,17,21-trihydroxy-16β- methylpregna-1,4-diene-3,20-dione 17,21-dipropionate, with the empirical formula C28H37FO7, a molecular weight of 504.6, and the following structural formula: Betamethasone dipropionate is a white to creamy white, odorless crystalline powder, insoluble in water. Each gram of DIPROSONE Cream 0.05% contains: 0.643 mg betamethasone dipropionate, USP (equivalent to 0.5 mg betamethasone) in a hydrophilic emollient cream consisting of purified water, USP; mineral oil, USP; white petrolatum, USP; ceteareth-30; cetearyl alcohol 70/30 (7.2%); sodium phosphate monobasic monohydrate R; and This label may not be the latest approved by FDA.

May also contain sodium hydroxide R to adjust pH to approximately 5.0. CLINICAL PHARMACOLOGY The corticosteroids are a class of compounds comprising steroid hormones, secreted by the adrenal cortex and their synthetic analogs. In pharmacologic doses corticosteroids are used primarily for their anti-inflammatory and/or immunosuppressive effects. Topical corticosteroids, such as betamethasone dipropionate, are effective in the treatment of corticosteroid-responsive dermatoses primarily because of their anti- inflammatory, antipruritic, and vasoconstrictive actions. However, while the physiologic, pharmacologic, and clinical effects of the corticosteroids are well known, the exact mechanisms of their actions in each disease are uncertain. Betamethasone dipropionate, a corticosteroid, has been shown to have topical (dermatologic) and systemic pharmacologic and metabolic effects characteristic of this class of drugs. Pharmacokinetics The extent of percutaneous absorption of topical corticosteroids is determined by many factors including the vehicle, the integrity of the epidermal barrier, and the use of occlusive dressings. (See DOSAGE AND ADMINISTRATION.) Topical corticosteroids can be absorbed from normal intact skin. Inflammation and/or other disease processes in the skin increase percutaneous absorption. Occlusive dressings substantially increase the percutaneous absorption of topical corticosteroids. (See DOSAGE AND ADMINISTRATION.) Once absorbed through the skin, topical corticosteroids are handled through pharmacokinetic pathways similar to systemically administered corticosteroids. Corticosteroids are bound to plasma proteins in varying degrees. Corticosteroids are metabolized primarily in the liver and are then excreted by the kidneys. Some of the topical corticosteroids and their metabolites are also excreted into the bile. Sixty-three pediatric patients ages 1 to 12 years, with atopic dermatitis, were enrolled in an open-label, hypothalamic-pituitary-adrenal (HPA) axis safety study. DIPROSONE Cream was applied twice daily for 2 to 3 weeks over a mean body surface area of 40% (range 35% to 90%). In 10 of 43 (23%) evaluable patients, adrenal This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda SCH 11460 SECTION 2 DIPROSONE CREAM PAGE 3 DRAFT LABELING suppression was indicated by either a ≤ 5 mcg/dL pre-stimulation cortisol, or a cosyntropin post-stimulation cortisol ≤ 18 mcg/dL and/or an increase of < 7 mcg/dL from the baseline cortisol. Studies performed with DIPROSONE Cream indicate that it is in the medium range of potency as compared with other topical corticosteroids. INDICATIONS AND USAGE DIPROSONE Cream is a medium-potency corticosteroid indicated for relief of the inflammatory and pruritic manifestations of corticosteroid- responsive dermatoses in patients 13 years and older. CONTRAINDICATIONS DIPROSONE Cream is contraindicated in patients who are hypersensitive to betamethasone dipropionate, to other corticosteroids, or to any ingredient in this preparation. PRECAUTIONS General Systemic absorption of topical corticosteroids has produced reversible hypothalamic-pituitary-adrenal (HPA) axis suppression, manifestations of Cushing's syndrome, hyperglycemia, and glucosuria in some patients. Conditions which augment systemic absorption include the application of the more potent steroids, use over large surface areas, prolonged use, and the addition of occlusive dressings. Use of more than one corticosteroid-containing product at the same time may increase total systemic glucocorticoid exposure. (See DOSAGE AND ADMINISTRATION.) Therefore, patients receiving a large dose of a potent topical steroid applied to a large surface area should be evaluated periodically for evidence of HPA axis suppression by using the urinary-free cortisol and ACTH stimulation tests. If HPA axis suppression is noted, an attempt should be made to withdraw the drug, to reduce the frequency of application, or to substitute a less potent steroid. Recovery of HPA axis function is generally prompt and complete upon discontinuation of the drug. In an open-label pediatric study of 43 evaluable patients, of the 10 subjects who showed evidence of suppression, 2 subjects were tested 2 weeks after discontinuation of DIPROSONE cream, 0.05%, and 1 of the 2 (50%) had complete This label may not be the latest approved by FDA.

Infrequently, signs and symptoms of steroid withdrawal may occur, requiring supplemental systemic corticosteroids. Pediatric patients may absorb proportionally larger amounts of topical corticosteroids and thus be more susceptible to systemic toxicity. (See PRECAUTIONS - Pediatric Use.) If irritation develops, topical corticosteroids should be discontinued and appropriate therapy instituted. In the presence of dermatological infections, the use of an appropriate antifungal or antibacterial agent should be instituted. If a favorable response does not occur promptly, the corticosteroid should be discontinued until the infection has been adequately controlled. Information for Patients This information is intended to aid in the safe and effective use of this medication. It is not a disclosure of all possible adverse or intended effects. Patients using topical corticosteroids should receive the following information and instructions: 1. This medication is to be used as directed by the physician. It is for external use only. Avoid contact with the eyes. 2. Patients should be advised not to use this medication for any disorder other than that for which it was prescribed. 3. The treated skin area should not be bandaged or otherwise covered or wrapped as to be occlusive. (See DOSAGE AND ADMINISTRATION.) 4. Patients should report any signs of local adverse reactions. 5. Other corticosteroid-containing products should not be used with DIPROSONE Cream without first talking to your physician. Laboratory Tests The following tests may be helpful in evaluating HPA axis suppression: Urinary-free cortisol test ACTH stimulation test This label may not be the latest approved by FDA.

Betamethasone was negative in the bacterial mutagenicity assay (Salmonella typhimurium and Escherichia coli), and in the mammalian cell mutagenicity assay (CHO/HGPRT). It was positive in the in-vitro human lymphocyte chromosome aberration assay, and equivocal in the in-vivo mouse bone marrow micronucleus assay. This pattern of response is similar to that of dexamethasone and hydrocortisone. Reproductive studies with betamethasone dipropionate carried out in rabbits at doses of 1.0 mg/kg by the intramuscular route and in mice up to 33 mg/kg by the intramuscular route indicated no impairment of fertility except for dose-related increases in fetal resorption rates in both species. These doses are approximately 0.5 and 4 fold the estimated maximum human dose based on a mg/m2 comparison, respectively. Pregnancy: Teratogenic effects: Pregnancy Category C: Corticosteroids are generally teratogenic in laboratory animals when administered systemically at relatively low dosage levels. Betamethasone dipropionate has been shown to be teratogenic in rabbits when given by the intramuscular route at doses of 0.05 mg/kg. This dose is approximately 0.03 fold the estimated maximum human dose based on a mg/m2 comparison. The abnormalities observed included umbilical hernias, cephalocele and cleft palates. Some corticosteroids have been shown to be teratogenic after dermal application in laboratory animals. There are no adequate and well-controlled studies in pregnant women on teratogenic effects from topically applied corticosteroids. Therefore, topical corticosteroids should be used during pregnancy only if the potential benefit justifies the This label may not be the latest approved by FDA.

Drugs of this class should not be used extensively on pregnant patients, in large amounts, or for prolonged periods of time. Nursing Mothers It is not known whether topical administration of corticosteroids could result in sufficient systemic absorption to produce detectable quantities in breast milk. Systemically administered corticosteroids are secreted into breast milk in quantities not likely to have a deleterious effect on the infant. Nevertheless, caution should be exercised when topical corticosteroids are prescribed for a nursing woman. Pediatric Use Use of DIPROSONE cream, 0.05%, in pediatric patients 12 years of age and younger is not recommended. (See CLINICAL PHARMACOLOGY and ADVERSE REACTIONS Sections.) In an open-label study, 10 of 43 (23%) evaluable pediatric patients (aged 2 years – 12 years old) using DIPROSONE Cream for treatment of atopic dermatitis for 2-3 weeks demonstrated HPA axis suppression. The proportion of patients with adrenal suppression in this study was progressively greater, the younger the age group. (See CLINICAL PHARMACOLOGY - Pharmacokinetics.) Pediatric patients may demonstrate greater susceptibility to topical corticosteroid- induced HPA axis suppression and Cushing's syndrome than mature patients because of a larger skin surface area to body weight ratio. The study described above supports this premise, as suppression in 9-12 year olds, 6-8 year olds, and 2-5 year olds was 14%, 23%, and 30%, respectively. Hypothalamic-pituitary-adrenal (HPA) axis suppression, Cushing's syndrome, and intracranial hypertension have been reported in pediatric patients receiving topical corticosteroids. Manifestations of adrenal suppression in pediatric patients include linear growth retardation, delayed weight gain, low plasma cortisol levels, and absence of response to ACTH stimulation. Manifestations of intracranial hypertension include bulging fontanelles, headaches, and bilateral papilledema. Administration of topical corticosteroids to pediatric patients should be limited to the least amount compatible with an effective therapeutic regimen. Chronic corticosteroid therapy may interfere with the growth and development of pediatric patients. This label may not be the latest approved by FDA.

These reactions are listed in an approximate decreasing order of occurrence: burning, itching, irritation, dryness, folliculitis, hypertrichosis, acneiform eruptions, hypopigmentation, perioral dermatitis, allergic contact dermatitis, maceration of the skin, secondary infection, skin atrophy, striae, miliaria. Adverse reactions reported to be possibly or probably related to treatment with DIPROSONE cream during a pediatric clinical study include signs of skin atrophy (bruising, shininess). Skin atrophy occurred in 3 of 63 (5%) patients, a 3-year old, a 5- year old, and a 7-year old. Systemic absorption of topical corticosteroids has produced reversible hypothalamic-pituitary-adrenal (HPA) axis suppression, manifestations of Cushing's syndrome, hyperglycemia, and glucosuria in some patients. OVERDOSAGE Topically applied corticosteroids can be absorbed in sufficient amounts to produce systemic effects. (See PRECAUTIONS.) DOSAGE AND ADMINISTRATION Apply a thin film of DIPROSONE Cream 0.05% to the affected skin areas once daily. In some cases, a twice-daily dosage may be necessary. DIPROSONE Cream is not to be used with occlusive dressings. HOW SUPPLIED DIPROSONE Cream 0.05% is supplied in 15-g (NDC 0085-0853-02) and 45-g (NDC 0085-0853-03) tubes; boxes of one.

Roche Logo KLONOPIN® TABLETS (clonazepam) KLONOPIN® WAFERS (clonazepam orally disintegrating tablets) Rx only DESCRIPTION Klonopin, a benzodiazepine, is available as scored tablets with a K-shaped perforation containing 0.5 mg of clonazepam and unscored tablets with a K-shaped perforation containing 1 mg or 2 mg of clonazepam. Each tablet also contains lactose, magnesium stearate, microcrystalline cellulose and corn starch, with the following colorants: 0.5 mg—FD&C Yellow No. 6 Lake; 1 mg—FD&C Blue No. 1 Lake and FD&C Blue No. 2 Lake. Klonopin is also available as an orally disintegrating tablet containing 0.125 mg, 0.25 mg, 0.5 mg, 1 mg or 2 mg clonazepam. Each orally disintegrating tablet also contains gelatin, mannitol, methylparaben sodium, propylparaben sodium and xanthan gum. Chemically, clonazepam is 5-(2-chlorophenyl)-1,3-dihydro-7-nitro-2H-1,4­ benzodiazepin-2-one. It is a light yellow crystalline powder. It has a molecular weight of 315.72 and the following structural formula: Chemical Structure of clonazepam CLINICAL PHARMACOLOGY Pharmacodynamics: The precise mechanism by which clonazepam exerts its antiseizure and antipanic effects is unknown, although it is believed to be related to its ability to enhance the activity of gamma aminobutyric acid (GABA), the major inhibitory neurotransmitter in the central nervous system. Convulsions produced in rodents by pentylenetetrazol or, to a lesser extent, electrical stimulation are antagonized, as are convulsions produced by photic stimulation in susceptible baboons. A taming effect in aggressive primates, muscle weakness and hypnosis are also produced. In humans, clonazepam is capable of suppressing the spike and wave discharge in absence seizures (petit mal) and decreasing the frequency, amplitude, duration and spread of discharge in minor motor seizures. Pharmacokinetics: Clonazepam is rapidly and completely absorbed after oral administration. The absolute bioavailability of clonazepam is about 90%. Maximum plasma concentrations of clonazepam are reached within 1 to 4 hours after oral administration. Clonazepam is approximately 85% bound to plasma proteins. Clonazepam is highly metabolized, with less than 2% unchanged clonazepam being excreted in the urine. Biotransformation occurs mainly by reduction of the 7-nitro group to the 4-amino derivative. This derivative can be acetylated, hydroxylated and glucuronidated. Cytochrome P-450 including CYP3A, may play an important role in clonazepam reduction and oxidation. The elimination half-life of clonazepam is typically 30 to 40 hours. Clonazepam pharmacokinetics are dose-independent throughout the dosing range. There is no evidence that clonazepam induces its own metabolism or that of other drugs in humans. Pharmacokinetics in Demographic Subpopulations and in Disease States: Controlled studies examining the influence of gender and age on clonazepam pharmacokinetics have not been conducted, nor have the effects of renal or liver disease on clonazepam pharmacokinetics been studied. Because clonazepam undergoes hepatic metabolism, it is possible that liver disease will impair clonazepam elimination. Thus, caution should be exercised when administering clonazepam to these patients. Clinical Trials: Panic Disorder: The effectiveness of Klonopin in the treatment of panic disorder was demonstrated in two double-blind, placebo-controlled studies of adult outpatients who had a primary diagnosis of panic disorder (DSM-IIIR) with or without agoraphobia. In these studies, Klonopin was shown to be significantly more effective than placebo in treating panic disorder on change from baseline in panic attack frequency, the Clinician’s Global Impression Severity of Illness Score and the Clinician’s Global Impression Improvement Score. Study 1 was a 9-week, fixed-dose study involving Klonopin doses of 0.5, 1, 2, 3 or 4 mg/day or placebo. This study was conducted in four phases: a 1-week placebo lead-in, a 3-week upward titration, a 6-week fixed dose and a 7-week discontinuance phase. A significant difference from placebo was observed consistently only for the 1 mg/day group. The difference between the 1 mg dose group and placebo in reduction from baseline in the number of full panic attacks was approximately 1 panic attack per week. At endpoint, 74% of patients receiving clonazepam 1 mg/day were free of full panic attacks, compared to 56% of placebo-treated patients. Study 2 was a 6-week, flexible-dose study involving Klonopin in a dose range of 0.5 to 4 mg/day or placebo. This study was conducted in three phases: a 1-week placebo lead-in, a 6-week optimal-dose and a 6-week discontinuance phase. The mean clonazepam dose during the optimal dosing period was 2.3 mg/day. The difference between Klonopin and placebo in reduction from baseline in the number of full panic attacks was approximately 1 panic attack per week. At endpoint, 62% of patients receiving clonazepam were free of full panic attacks, compared to 37% of placebo-treated patients. Subgroup analyses did not indicate that there were any differences in treatment outcomes as a function of race or gender. Page 2 of 19 INDICATIONS AND USAGE Seizure Disorders: Klonopin is useful alone or as an adjunct in the treatment of the Lennox-Gastaut syndrome (petit mal variant), akinetic and myoclonic seizures. In patients with absence seizures (petit mal) who have failed to respond to succinimides, Klonopin may be useful. In some studies, up to 30% of patients have shown a loss of anticonvulsant activity, often within 3 months of administration. In some cases, dosage adjustment may reestablish efficacy. Panic Disorder: Klonopin is indicated for the treatment of panic disorder, with or without agoraphobia, as defined in DSM-IV. Panic disorder is characterized by the occurrence of unexpected panic attacks and associated concern about having additional attacks, worry about the implications or consequences of the attacks, and/or a significant change in behavior related to the attacks. The efficacy of Klonopin was established in two 6- to 9-week trials in panic disorder patients whose diagnoses corresponded to the DSM-IIIR category of panic disorder (see CLINICAL PHARMACOLOGY: Clinical Trials). Panic disorder (DSM-IV) is characterized by recurrent unexpected panic attacks, ie, a discrete period of intense fear or discomfort in which four (or more) of the following symptoms develop abruptly and reach a peak within 10 minutes: (1) palpitations, pounding heart or accelerated heart rate; (2) sweating; (3) trembling or shaking; (4) sensations of shortness of breath or smothering; (5) feeling of choking; (6) chest pain or discomfort; (7) nausea or abdominal distress; (8) feeling dizzy, unsteady, lightheaded or faint; (9) derealization (feelings of unreality) or depersonalization (being detached from oneself); (10) fear of losing control; (11) fear of dying; (12) paresthesias (numbness or tingling sensations); (13) chills or hot flushes. The effectiveness of Klonopin in long-term use, that is, for more than 9 weeks, has not been systematically studied in controlled clinical trials. The physician who elects to use Klonopin for extended periods should periodically reevaluate the long-term usefulness of the drug for the individual patient (see DOSAGE AND ADMINISTRATION). CONTRAINDICATIONS Klonopin should not be used in patients with a history of sensitivity to benzodiazepines, nor in patients with clinical or biochemical evidence of significant liver disease. It may be used in patients with open angle glaucoma who are receiving appropriate therapy but is contraindicated in acute narrow angle glaucoma. WARNINGS Interference With Cognitive and Motor Performance: Since Klonopin produces CNS depression, patients receiving this drug should be cautioned against engaging in hazardous occupations requiring mental alertness, such as operating machinery or driving a motor vehicle. They should also be warned about the concomitant use of alcohol or other CNS-depressant drugs during Klonopin therapy (see PRECAUTIONS: Drug Interactions and Information for Patients). Page 3 of 19 Suicidal Behavior and Ideation: Antiepileptic drugs (AEDs), including Klonopin, increase the risk of suicidal thoughts or behavior in patients taking these drugs for any indication. Patients treated with any AED for any indication should be monitored for the emergence or worsening of depression, suicidal thoughts or behavior, and/or any unusual changes in mood or behavior. Pooled analyses of 199 placebo-controlled clinical trials (mono- and adjunctive therapy) of 11 different AEDs showed that patients randomized to one of the AEDs had approximately twice the risk (adjusted Relative Risk 1.8, 95% CI:1.2, 2.7) of suicidal thinking or behavior compared to patients randomized to placebo. In these trials, which had a median treatment duration of 12 weeks, the estimated incidence rate of suicidal behavior or ideation among 27,863 AED-treated patients was 0.43% compared to 0.24% among 16,029 placebo-treated patients, representing an increase of approximately one case of suicidal thinking or behavior for every 530 patients treated. There were four suicides in drug-treated patients in the trials and none in placebo-treated patients, but the number is too small to allow any conclusion about drug effect on suicide. The increased risk of suicidal thoughts or behavior with AEDs was observed as early as one week after starting drug treatment with AEDs and persisted for the duration of treatment assessed. Because most trials included in the analysis did not extend beyond 24 weeks, the risk of suicidal thoughts or behavior beyond 24 weeks could not be assessed. The risk of suicidal thoughts or behavior was generally consistent among drugs in the data analyzed. The finding of increased risk with AEDs of varying mechanisms of action and across a range of indications suggests that the risk applies to all AEDs used for any indication. The risk did not vary substantially by age (5-100 years) in the clinical trials analyzed. Table 1 shows absolute and relative risk by indication for all evaluated AEDs. Table 1 Risk by Indication for Antiepileptic Drugs in the Pooled Analysis Indication Placebo Patients with Events Per 1000 Patients Drug Patients with Events Per 1000 Patients Relative Risk: Incidence of Events in Drug Patients/Incidence in Placebo Patients Risk Difference: Additional Drug Patients with Events per 1000 Patients Epilepsy Psychiatric Other Total 1.0 5.7 1.0 2.4 3.4 8.5 1.8 4.3 3.5 1.5 1.9 1.8 2.4 2.9 0.9 1.9 The relative risk for suicidal thoughts or behavior was higher in clinical trials for epilepsy than in clinical trials for psychiatric or other conditions, but the absolute risk differences were similar for the epilepsy and psychiatric indications. Anyone considering prescribing Klonopin or any other AED must balance the risk of suicidal thoughts or behavior with the risk of untreated illness. Epilepsy and many other illnesses for which AEDs are prescribed are themselves associated with morbidity and Page 4 of 19 mortality and an increased risk of suicidal thoughts and behavior. Should suicidal thoughts and behavior emerge during treatment, the prescriber needs to consider whether the emergence of these symptoms in any given patient may be related to the illness being treated. Patients, their caregivers, and families should be informed that AEDs increase the risk of suicidal thoughts and behavior and should be advised of the need to be alert for the emergence or worsening of the signs and symptoms of depression, any unusual changes in mood or behavior, or the emergence of suicidal thoughts, behavior, or thoughts about self-harm. Behaviors of concern should be reported immediately to healthcare providers. Pregnancy Risks: Data from several sources raise concerns about the use of Klonopin during pregnancy. Animal Findings: In three studies in which Klonopin was administered orally to pregnant rabbits at doses of 0.2, 1, 5 or 10 mg/kg/day (low dose approximately 0.2 times the maximum recommended human dose of 20 mg/day for seizure disorders and equivalent to the maximum dose of 4 mg/day for panic disorder, on a mg/m2 basis) during the period of organogenesis, a similar pattern of malformations (cleft palate, open eyelid, fused sternebrae and limb defects) was observed in a low, non-dose-related incidence in exposed litters from all dosage groups. Reductions in maternal weight gain occurred at dosages of 5 mg/kg/day or greater and reduction in embryo-fetal growth occurred in one study at a dosage of 10 mg/kg/day. No adverse maternal or embryo-fetal effects were observed in mice and rats following administration during organogenesis of oral doses up to 15 mg/kg/day or 40 mg/kg/day, respectively (4 and 20 times the maximum recommended human dose of 20 mg/day for seizure disorders and 20 and 100 times the maximum dose of 4 mg/day for panic disorder, respectively, on a mg/m2 basis). General Concerns and Considerations About Anticonvulsants: Recent reports suggest an association between the use of anticonvulsant drugs by women with epilepsy and an elevated incidence of birth defects in children born to these women. Data are more extensive with respect to diphenylhydantoin and phenobarbital, but these are also the most commonly prescribed anticonvulsants; less systematic or anecdotal reports suggest a possible similar association with the use of all known anticonvulsant drugs. In children of women treated with drugs for epilepsy, reports suggesting an elevated incidence of birth defects cannot be regarded as adequate to prove a definite cause and effect relationship. There are intrinsic methodologic problems in obtaining adequate data on drug teratogenicity in humans; the possibility also exists that other factors (eg, genetic factors or the epileptic condition itself) may be more important than drug therapy in leading to birth defects. The great majority of mothers on anticonvulsant medication deliver normal infants. It is important to note that anticonvulsant drugs should not be discontinued in patients in whom the drug is administered to prevent seizures because of the strong possibility of precipitating status epilepticus with attendant hypoxia and threat to life. In individual cases where the severity and frequency of the seizure disorder are such that the removal of medication does not pose a serious threat to the patient, Page 5 of 19 discontinuation of the drug may be considered prior to and during pregnancy; however, it cannot be said with any confidence that even mild seizures do not pose some hazards to the developing embryo or fetus. General Concerns About Benzodiazepines: An increased risk of congenital malformations associated with the use of benzodiazepine drugs has been suggested in several studies. There may also be non-teratogenic risks associated with the use of benzodiazepines during pregnancy. There have been reports of neonatal flaccidity, respiratory and feeding difficulties, and hypothermia in children born to mothers who have been receiving benzodiazepines late in pregnancy. In addition, children born to mothers receiving benzodiazepines late in pregnancy may be at some risk of experiencing withdrawal symptoms during the postnatal period. Advice Regarding the Use of Klonopin in Women of Childbearing Potential: In general, the use of Klonopin in women of childbearing potential, and more specifically during known pregnancy, should be considered only when the clinical situation warrants the risk to the fetus. The specific considerations addressed above regarding the use of anticonvulsants for epilepsy in women of childbearing potential should be weighed in treating or counseling these women. Because of experience with other members of the benzodiazepine class, Klonopin is assumed to be capable of causing an increased risk of congenital abnormalities when administered to a pregnant woman during the first trimester. Because use of these drugs is rarely a matter of urgency in the treatment of panic disorder, their use during the first trimester should almost always be avoided. The possibility that a woman of childbearing potential may be pregnant at the time of institution of therapy should be considered. If this drug is used during pregnancy, or if the patient becomes pregnant while taking this drug, the patient should be apprised of the potential hazard to the fetus. Patients should also be advised that if they become pregnant during therapy or intend to become pregnant, they should communicate with their physician about the desirability of discontinuing the drug. Withdrawal Symptoms: Withdrawal symptoms of the barbiturate type have occurred after the discontinuation of benzodiazepines (see DRUG ABUSE AND DEPENDENCE). PRECAUTIONS General: Worsening of Seizures: When used in patients in whom several different types of seizure disorders coexist, Klonopin may increase the incidence or precipitate the onset of generalized tonic-clonic seizures (grand mal). This may require the addition of appropriate anticonvulsants or an increase in their dosages. The concomitant use of valproic acid and Klonopin may produce absence status. Laboratory Testing During Long-Term Therapy: Periodic blood counts and liver function tests are advisable during long-term therapy with Klonopin. Page 6 of 19 Risks of Abrupt Withdrawal: The abrupt withdrawal of Klonopin, particularly in those patients on long-term, high-dose therapy, may precipitate status epilepticus. Therefore, when discontinuing Klonopin, gradual withdrawal is essential. While Klonopin is being gradually withdrawn, the simultaneous substitution of another anticonvulsant may be indicated. Caution in Renally Impaired Patients: Metabolites of Klonopin are excreted by the kidneys; to avoid their excess accumulation, caution should be exercised in the administration of the drug to patients with impaired renal function. Hypersalivation: Klonopin may produce an increase in salivation. This should be considered before giving the drug to patients who have difficulty handling secretions. Because of this and the possibility of respiratory depression, Klonopin should be used with caution in patients with chronic respiratory diseases. Information for Patients: Patients should be instructed to take Klonopin only as prescribed. Physicians are advised to discuss the following issues with patients for whom they prescribe Klonopin: Dose Changes: To assure the safe and effective use of benzodiazepines, patients should be informed that, since benzodiazepines may produce psychological and physical dependence, it is advisable that they consult with their physician before either increasing the dose or abruptly discontinuing this drug. Interference With Cognitive and Motor Performance: Because benzodiazepines have the potential to impair judgment, thinking or motor skills, patients should be cautioned about operating hazardous machinery, including automobiles, until they are reasonably certain that Klonopin therapy does not affect them adversely. Suicidal Thinking and Behavior: Patients, their caregivers, and families should be counseled that AEDs, including Klonopin, may increase the risk of suicidal thoughts and behavior and should be advised of the need to be alert for the emergence or worsening of symptoms of depression, any unusual changes in mood or behavior, or the emergence of suicidal thoughts, behavior, or thoughts about self-harm. Behaviors of concern should be reported immediately to healthcare providers. Pregnancy: Patients should be advised to notify their physician if they become pregnant or intend to become pregnant during therapy with Klonopin (see WARNINGS: Pregnancy Risks). Patients should be encouraged to enroll in the North American Antiepileptic Drug (NAAED) Pregnancy Registry if they become pregnant. This registry is collecting information about the safety of antiepileptic drugs during pregnancy. To enroll, patients can call the toll free number 1-888-233-2334 (see PRECAUTIONS: Pregnancy). Nursing: Patients should be advised not to breastfeed an infant if they are taking Klonopin. Page 7 of 19 Concomitant Medication: Patients should be advised to inform their physicians if they are taking, or plan to take, any prescription or over-the-counter drugs, since there is a potential for interactions. Alcohol: Patients should be advised to avoid alcohol while taking Klonopin. Drug Interactions: Effect of Clonazepam on the Pharmacokinetics of Other Drugs: Clonazepam does not appear to alter the pharmacokinetics of phenytoin, carbamazepine or phenobarbital. The effect of clonazepam on the metabolism of other drugs has not been investigated. Effect of Other Drugs on the Pharmacokinetics of Clonazepam: Literature reports suggest that ranitidine, an agent that decreases stomach acidity, does not greatly alter clonazepam pharmacokinetics. In a study in which the 2 mg clonazepam orally disintegrating tablet was administered with and without propantheline (an anticholinergic agent with multiple effects on the GI tract) to healthy volunteers, the AUC of clonazepam was 10% lower and the Cmax of clonazepam was 20% lower when the orally disintegrating tablet was given with propantheline compared to when it was given alone. Fluoxetine does not affect the pharmacokinetics of clonazepam. Cytochrome P-450 inducers, such as phenytoin, carbamazepine and phenobarbital, induce clonazepam metabolism, causing an approximately 30% decrease in plasma clonazepam levels. Although clinical studies have not been performed, based on the involvement of the cytochrome P-450 3A family in clonazepam metabolism, inhibitors of this enzyme system, notably oral antifungal agents, should be used cautiously in patients receiving clonazepam. Pharmacodynamic Interactions: The CNS-depressant action of the benzodiazepine class of drugs may be potentiated by alcohol, narcotics, barbiturates, nonbarbiturate hypnotics, antianxiety agents, the phenothiazines, thioxanthene and butyrophenone classes of antipsychotic agents, monoamine oxidase inhibitors and the tricyclic antidepressants, and by other anticonvulsant drugs. Carcinogenesis, Mutagenesis, Impairment of Fertility: Carcinogenicity studies have not been conducted with clonazepam. The data currently available are not sufficient to determine the genotoxic potential of clonazepam. In a two-generation fertility study in which clonazepam was given orally to rats at 10 and 100 mg/kg/day (low dose approximately 5 times and 24 times the maximum recommended human dose of 20 mg/day for seizure disorder and 4 mg/day for panic disorder, respectively, on a mg/m2 basis), there was a decrease in the number of pregnancies and in the number of offspring surviving until weaning. Pregnancy: Teratogenic Effects: Pregnancy Category D (see WARNINGS: Pregnancy Risks). Page 8 of 19 To provide information regarding the effects of in utero exposure to Klonopin, physicians are advised to recommend that pregnant patients taking Klonopin enroll in the NAAED Pregnancy Registry. This can be done by calling the toll free number 1-888-233-2334, and must be done by patients themselves. Information on this registry can also be found at the website http://www.aedpregnancyregistry.org/. Labor and Delivery: The effect of Klonopin on labor and delivery in humans has not been specifically studied; however, perinatal complications have been reported in children born to mothers who have been receiving benzodiazepines late in pregnancy, including findings suggestive of either excess benzodiazepine exposure or of withdrawal phenomena (see WARNINGS: Pregnancy Risks). Nursing Mothers: Mothers receiving Klonopin should not breastfeed their infants. Pediatric Use: Because of the possibility that adverse effects on physical or mental development could become apparent only after many years, a benefit-risk consideration of the long-term use of Klonopin is important in pediatric patients being treated for seizure disorder (see INDICATIONS AND USAGE and DOSAGE AND ADMINISTRATION). Safety and effectiveness in pediatric patients with panic disorder below the age of 18 have not been established. Geriatric Use: Clinical studies of Klonopin did not include sufficient numbers of subjects aged 65 and over to determine whether they respond differently from younger subjects. Other reported clinical experience has not identified differences in responses between the elderly and younger patients. In general, dose selection for an elderly patient should be cautious, usually starting at the low end of the dosing range, reflecting the greater frequency of decreased hepatic, renal, or cardiac function, and of concomitant disease or other drug therapy. Because clonazepam undergoes hepatic metabolism, it is possible that liver disease will impair clonazepam elimination. Metabolites of Klonopin are excreted by the kidneys; to avoid their excess accumulation, caution should be exercised in the administration of the drug to patients with impaired renal function. Because elderly patients are more likely to have decreased hepatic and/or renal function, care should be taken in dose selection, and it may be useful to assess hepatic and/or renal function at the time of dose selection. Sedating drugs may cause confusion and over-sedation in the elderly; elderly patients generally should be started on low doses of Klonopin and observed closely. ADVERSE REACTIONS The adverse experiences for Klonopin are provided separately for patients with seizure disorders and with panic disorder. Seizure Disorders: The most frequently occurring side effects of Klonopin are referable to CNS depression. Experience in treatment of seizures has shown that drowsiness has occurred in approximately 50% of patients and ataxia in approximately 30%. In some cases, these may diminish with time; behavior problems have been noted in approximately 25% of patients. Others, listed by system, are: Page 9 of 19 Neurologic: Abnormal eye movements, aphonia, choreiform movements, coma, diplopia, dysarthria, dysdiadochokinesis, ‘‘glassy-eyed’’ appearance, headache, hemiparesis, hypotonia, nystagmus, respiratory depression, slurred speech, tremor, vertigo Psychiatric: Confusion, depression, amnesia, hallucinations, hysteria, increased libido, insomnia, psychosis,(the behavior effects are more likely to occur in patients with a history of psychiatric disturbances). The following paradoxical reactions have been observed: excitability, irritability, aggressive behavior, agitation, nervousness, hostility, anxiety, sleep disturbances, nightmares and vivid dreams Respiratory: Chest congestion, rhinorrhea, shortness of breath, hypersecretion in upper respiratory passages Cardiovascular: Palpitations Dermatologic: Hair loss, hirsutism, skin rash, ankle and facial edema Gastrointestinal: Anorexia, coated tongue, constipation, diarrhea, dry mouth, encopresis, gastritis, increased appetite, nausea, sore gums Genitourinary: Dysuria, enuresis, nocturia, urinary retention Musculoskeletal: Muscle weakness, pains Miscellaneous: Dehydration, general deterioration, fever, lymphadenopathy, weight loss or gain Hematopoietic: Anemia, leukopenia, thrombocytopenia, eosinophilia Hepatic: Hepatomegaly, transient elevations of serum transaminases and alkaline phosphatase Panic Disorder: Adverse events during exposure to Klonopin were obtained by spontaneous report and recorded by clinical investigators using terminology of their own choosing. Consequently, it is not possible to provide a meaningful estimate of the proportion of individuals experiencing adverse events without first grouping similar types of events into a smaller number of standardized event categories. In the tables and tabulations that follow, CIGY dictionary terminology has been used to classify reported adverse events, except in certain cases in which redundant terms were collapsed into more meaningful terms, as noted below. The stated frequencies of adverse events represent the proportion of individuals who experienced, at least once, a treatment-emergent adverse event of the type listed. An event was considered treatment-emergent if it occurred for the first time or worsened while receiving therapy following baseline evaluation. Adverse Findings Observed in Short-Term, Placebo-Controlled Trials: Adverse Events Associated With Discontinuation of Treatment: Overall, the incidence of discontinuation due to adverse events was 17% in Klonopin compared to 9% for placebo in the combined data of two 6- to 9-week trials. The most Page 10 of 19 common events (≥1%) associated with discontinuation and a dropout rate twice or greater for Klonopin than that of placebo included the following: Table 2 Most Common Adverse Events (≥1%) Associated with Discontinuation of Treatment Adverse Event Klonopin (N=574) Placebo (N=294) Somnolence 7% 1% Depression 4% 1% Dizziness 1% <1% Nervousness 1% 0% Ataxia 1% 0% Intellectual Ability Reduced 1% 0% Adverse Events Occurring at an Incidence of 1% or More Among Klonopin-Treated Patients: Table 3 enumerates the incidence, rounded to the nearest percent, of treatment-emergent adverse events that occurred during acute therapy of panic disorder from a pool of two 6- to 9-week trials. Events reported in 1% or more of patients treated with Klonopin (doses ranging from 0.5 to 4 mg/day) and for which the incidence was greater than that in placebo-treated patients are included. The prescriber should be aware that the figures in Table 3 cannot be used to predict the incidence of side effects in the course of usual medical practice where patient characteristics and other factors differ from those that prevailed in the clinical trials. Similarly, the cited frequencies cannot be compared with figures obtained from other clinical investigations involving different treatments, uses and investigators. The cited figures, however, do provide the prescribing physician with some basis for estimating the relative contribution of drug and nondrug factors to the side effect incidence in the population studied.

Page 13 of 19 Commonly Observed Adverse Events: Table 4 Incidence of Most Commonly Observed Adverse Events* in Acute Therapy in Pool of 6- to 9-Week Trials Adverse Event (Roche Preferred Term) Clonazepam (N=574) Placebo (N=294) Somnolence 37% 10% Depression 7% 1% Coordination Abnormal 6% 0% Ataxia 5% 0% * Treatment-emergent events for which the incidence in the clonazepam patients was ≥5% and at least twice that in the placebo patients. Treatment-Emergent Depressive Symptoms: In the pool of two short-term placebo-controlled trials, adverse events classified under the preferred term “depression” were reported in 7% of Klonopin-treated patients compared to 1% of placebo-treated patients, without any clear pattern of dose relatedness. In these same trials, adverse events classified under the preferred term “depression” were reported as leading to discontinuation in 4% of Klonopin-treated patients compared to 1% of placebo-treated patients. While these findings are noteworthy, Hamilton Depression Rating Scale (HAM-D) data collected in these trials revealed a larger decline in HAM-D scores in the clonazepam group than the placebo group suggesting that clonazepam­ treated patients were not experiencing a worsening or emergence of clinical depression. Other Adverse Events Observed During the Premarketing Evaluation of Klonopin in Panic Disorder: Following is a list of modified CIGY terms that reflect treatment-emergent adverse events reported by patients treated with Klonopin at multiple doses during clinical trials. All reported events are included except those already listed in Table 3 or elsewhere in labeling, those events for which a drug cause was remote, those event terms which were so general as to be uninformative, and events reported only once and which did not have a substantial probability of being acutely life-threatening. It is important to emphasize that, although the events occurred during treatment with Klonopin, they were not necessarily caused by it. Events are further categorized by body system and listed in order of decreasing frequency. These adverse events were reported infrequently, which is defined as occurring in 1/100 to 1/1000 patients. Body as a Whole: weight increase, accident, weight decrease, wound, edema, fever, shivering, abrasions, ankle edema, edema foot, edema periorbital, injury, malaise, pain, cellulitis, inflammation localized Cardiovascular Disorders: chest pain, hypotension postural Page 14 of 19 Central and Peripheral Nervous System Disorders: migraine, paresthesia, drunkenness, feeling of enuresis, paresis, tremor, burning skin, falling, head fullness, hoarseness, hyperactivity, hypoesthesia, tongue thick, twitching Gastrointestinal System Disorders: abdominal discomfort, gastrointestinal inflammation, stomach upset, toothache, flatulence, pyrosis, saliva increased, tooth disorder, bowel movements frequent, pain pelvic, dyspepsia, hemorrhoids Hearing and Vestibular Disorders: vertigo, otitis, earache, motion sickness Heart Rate and Rhythm Disorders: palpitation Metabolic and Nutritional Disorders: thirst, gout Musculoskeletal System Disorders: back pain, fracture traumatic, sprains and strains, pain leg, pain nape, cramps muscle, cramps leg, pain ankle, pain shoulder, tendinitis, arthralgia, hypertonia, lumbago, pain feet, pain jaw, pain knee, swelling knee Platelet, Bleeding and Clotting Disorders: bleeding dermal Psychiatric Disorders: insomnia, organic disinhibition, anxiety, depersonalization, dreaming excessive, libido loss, appetite increased, libido increased, reactions decreased, aggressive reaction, apathy, attention lack, excitement, feeling mad, hunger abnormal, illusion, nightmares, sleep disorder, suicide ideation, yawning Reproductive Disorders, Female: breast pain, menstrual irregularity Reproductive Disorders, Male: ejaculation decreased Resistance Mechanism Disorders: infection mycotic, infection viral, infection streptococcal, herpes simplex infection, infectious mononucleosis, moniliasis Respiratory System Disorders: sneezing excessive, asthmatic attack, dyspnea, nosebleed, pneumonia, pleurisy Skin and Appendages Disorders: acne flare, alopecia, xeroderma, dermatitis contact, flushing, pruritus, pustular reaction, skin burns, skin disorder Special Senses Other, Disorders: taste loss Urinary System Disorders: dysuria, cystitis, polyuria, urinary incontinence, bladder dysfunction, urinary retention, urinary tract bleeding, urine discoloration Vascular (Extracardiac) Disorders: thrombophlebitis leg Vision Disorders: eye irritation, visual disturbance, diplopia, eye twitching, styes, visual field defect, xerophthalmia DRUG ABUSE AND DEPENDENCE Controlled Substance Class: Clonazepam is a Schedule IV controlled substance. Physical and Psychological Dependence: Withdrawal symptoms, similar in character to those noted with barbiturates and alcohol (eg, convulsions, psychosis, hallucinations, Page 15 of 19 behavioral disorder, tremor, abdominal and muscle cramps) have occurred following abrupt discontinuance of clonazepam. The more severe withdrawal symptoms have usually been limited to those patients who received excessive doses over an extended period of time. Generally milder withdrawal symptoms (eg, dysphoria and insomnia) have been reported following abrupt discontinuance of benzodiazepines taken continuously at therapeutic levels for several months. Consequently, after extended therapy, abrupt discontinuation should generally be avoided and a gradual dosage tapering schedule followed (see DOSAGE AND ADMINISTRATION). Addiction-prone individuals (such as drug addicts or alcoholics) should be under careful surveillance when receiving clonazepam or other psychotropic agents because of the predisposition of such patients to habituation and dependence. Following the short-term treatment of patients with panic disorder in Studies 1 and 2 (see CLINICAL PHARMACOLOGY: Clinical Trials), patients were gradually withdrawn during a 7-week downward-titration (discontinuance) period. Overall, the discontinuance period was associated with good tolerability and a very modest clinical deterioration, without evidence of a significant rebound phenomenon. However, there are not sufficient data from adequate and well-controlled long-term clonazepam studies in patients with panic disorder to accurately estimate the risks of withdrawal symptoms and dependence that may be associated with such use. OVERDOSAGE Human Experience: Symptoms of clonazepam overdosage, like those produced by other CNS depressants, include somnolence, confusion, coma and diminished reflexes. Overdose Management: Treatment includes monitoring of respiration, pulse and blood pressure, general supportive measures and immediate gastric lavage. Intravenous fluids should be administered and an adequate airway maintained. Hypotension may be combated by the use of levarterenol or metaraminol. Dialysis is of no known value. Flumazenil, a specific benzodiazepine-receptor antagonist, is indicated for the complete or partial reversal of the sedative effects of benzodiazepines and may be used in situations when an overdose with a benzodiazepine is known or suspected. Prior to the administration of flumazenil, necessary measures should be instituted to secure airway, ventilation and intravenous access. Flumazenil is intended as an adjunct to, not as a substitute for, proper management of benzodiazepine overdose. Patients treated with flumazenil should be monitored for resedation, respiratory depression and other residual benzodiazepine effects for an appropriate period after treatment. The prescriber should be aware of a risk of seizure in association with flumazenil treatment, particularly in long-term benzodiazepine users and in cyclic antidepressant overdose. The complete flumazenil package insert, including CONTRAINDICATIONS, WARNINGS and PRECAUTIONS, should be consulted prior to use. Flumazenil is not indicated in patients with epilepsy who have been treated with benzodiazepines. Antagonism of the benzodiazepine effect in such patients may provoke seizures. Serious sequelae are rare unless other drugs or alcohol have been taken concomitantly. Page 16 of 19 DOSAGE AND ADMINISTRATION Clonazepam is available as a tablet or an orally disintegrating tablet (wafer). The tablets should be administered with water by swallowing the tablet whole. The orally disintegrating tablet should be administered as follows: After opening the pouch, peel back the foil on the blister. Do not push tablet through foil. Immediately upon opening the blister, using dry hands, remove the tablet and place it in the mouth. Tablet disintegration occurs rapidly in saliva so it can be easily swallowed with or without water. Seizure Disorders: Adults: The initial dose for adults with seizure disorders should not exceed 1.5 mg/day divided into three doses. Dosage may be increased in increments of 0.5 to 1 mg every 3 days until seizures are adequately controlled or until side effects preclude any further increase. Maintenance dosage must be individualized for each patient depending upon response. Maximum recommended daily dose is 20 mg. The use of multiple anticonvulsants may result in an increase of depressant adverse effects. This should be considered before adding Klonopin to an existing anticonvulsant regimen. Pediatric Patients: Klonopin is administered orally. In order to minimize drowsiness, the initial dose for infants and children (up to 10 years of age or 30 kg of body weight) should be between 0.01 and 0.03 mg/kg/day but not to exceed 0.05 mg/kg/day given in two or three divided doses. Dosage should be increased by no more than 0.25 to 0.5 mg every third day until a daily maintenance dose of 0.1 to 0.2 mg/kg of body weight has been reached, unless seizures are controlled or side effects preclude further increase. Whenever possible, the daily dose should be divided into three equal doses. If doses are not equally divided, the largest dose should be given before retiring. Geriatric Patients: There is no clinical trial experience with Klonopin in seizure disorder patients 65 years of age and older. In general, elderly patients should be started on low doses of Klonopin and observed closely (see PRECAUTIONS: Geriatric Use). Panic Disorder: Adults: The initial dose for adults with panic disorder is 0.25 mg bid. An increase to the target dose for most patients of 1 mg/day may be made after 3 days. The recommended dose of 1 mg/day is based on the results from a fixed dose study in which the optimal effect was seen at 1 mg/day. Higher doses of 2, 3 and 4 mg/day in that study were less effective than the 1 mg/day dose and were associated with more adverse effects. Nevertheless, it is possible that some individual patients may benefit from doses of up to a maximum dose of 4 mg/day, and in those instances, the dose may be increased in increments of 0.125 to 0.25 mg bid every 3 days until panic disorder is controlled or until side effects make further increases undesired. To reduce the inconvenience of somnolence, administration of one dose at bedtime may be desirable. Treatment should be discontinued gradually, with a decrease of 0.125 mg bid every 3 days, until the drug is completely withdrawn. There is no body of evidence available to answer the question of how long the patient treated with clonazepam should remain on it. Therefore, the physician who elects to use Page 17 of 19 Klonopin for extended periods should periodically reevaluate the long-term usefulness of the drug for the individual patient. Pediatric Patients: There is no clinical trial experience with Klonopin in panic disorder patients under 18 years of age. Geriatric Patients: There is no clinical trial experience with Klonopin in panic disorder patients 65 years of age and older. In general, elderly patients should be started on low doses of Klonopin and observed closely (see PRECAUTIONS: Geriatric Use).

NDA 017533 Klonopin (clonazepam) tablets FDA Approved Labeling Text October 2013 KLONOPIN TABLETS (clonazepam) Rx only DESCRIPTION Klonopin, a benzodiazepine, is available as scored tablets with a K-shaped perforation containing 0.5 mg of clonazepam and unscored tablets with a K-shaped perforation containing 1 mg or 2 mg of clonazepam. Each tablet also contains lactose, magnesium stearate, microcrystalline cellulose and corn starch, with the following colorants: 0.5 mg—FD&C Yellow No. 6 Lake; 1 mg—FD&C Blue No. 1 Lake and FD&C Blue No. 2 Lake. Chemically, clonazepam is 5-(2-chlorophenyl)-1,3-dihydro-7-nitro-2H-1,4­ benzodiazepin-2-one. It is a light yellow crystalline powder. It has a molecular weight of 315.72 and the following structural formula: structural formula CLINICAL PHARMACOLOGY Pharmacodynamics: The precise mechanism by which clonazepam exerts its antiseizure and antipanic effects is unknown, although it is believed to be related to its ability to enhance the activity of gamma aminobutyric acid (GABA), the major inhibitory neurotransmitter in the central nervous system. Convulsions produced in rodents by pentylenetetrazol or, to a lesser extent, electrical stimulation are antagonized, as are convulsions produced by photic stimulation in susceptible baboons. A taming effect in aggressive primates, muscle weakness and hypnosis are also produced. In humans, clonazepam is capable of suppressing the spike and wave discharge in absence seizures (petit mal) and decreasing the frequency, amplitude, duration and spread of discharge in minor motor seizures. Pharmacokinetics: Clonazepam is rapidly and completely absorbed after oral administration. The absolute bioavailability of clonazepam is about 90%. Maximum plasma concentrations of clonazepam are reached within 1 to 4 hours after oral administration. Clonazepam is approximately 85% bound to plasma proteins. Clonazepam is highly metabolized, with less than 2% unchanged clonazepam being excreted in the urine. Biotransformation occurs mainly by reduction of the 7-nitro group Reference ID: 3398090 1 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda NDA 017533 Klonopin (clonazepam) tablets FDA Approved Labeling Text October 2013 to the 4-amino derivative. This derivative can be acetylated, hydroxylated and glucuronidated. Cytochrome P-450 including CYP3A, may play an important role in clonazepam reduction and oxidation. The elimination half-life of clonazepam is typically 30 to 40 hours. Clonazepam pharmacokinetics are dose-independent throughout the dosing range. There is no evidence that clonazepam induces its own metabolism or that of other drugs in humans. Pharmacokinetics in Demographic Subpopulations and in Disease States: Controlled studies examining the influence of gender and age on clonazepam pharmacokinetics have not been conducted, nor have the effects of renal or liver disease on clonazepam pharmacokinetics been studied. Because clonazepam undergoes hepatic metabolism, it is possible that liver disease will impair clonazepam elimination. Thus, caution should be exercised when administering clonazepam to these patients. Clinical Trials: Panic Disorder: The effectiveness of Klonopin in the treatment of panic disorder was demonstrated in two double-blind, placebo-controlled studies of adult outpatients who had a primary diagnosis of panic disorder (DSM-IIIR) with or without agoraphobia. In these studies, Klonopin was shown to be significantly more effective than placebo in treating panic disorder on change from baseline in panic attack frequency, the Clinician’s Global Impression Severity of Illness Score and the Clinician’s Global Impression Improvement Score. Study 1 was a 9-week, fixed-dose study involving Klonopin doses of 0.5, 1, 2, 3 or 4 mg/day or placebo. This study was conducted in four phases: a 1-week placebo lead-in, a 3-week upward titration, a 6-week fixed dose and a 7-week discontinuance phase. A significant difference from placebo was observed consistently only for the 1 mg/day group. The difference between the 1 mg dose group and placebo in reduction from baseline in the number of full panic attacks was approximately 1 panic attack per week. At endpoint, 74% of patients receiving clonazepam 1 mg/day were free of full panic attacks, compared to 56% of placebo-treated patients. Study 2 was a 6-week, flexible-dose study involving Klonopin in a dose range of 0.5 to 4 mg/day or placebo. This study was conducted in three phases: a 1-week placebo lead-in, a 6-week optimal-dose and a 6-week discontinuance phase. The mean clonazepam dose during the optimal dosing period was 2.3 mg/day. The difference between Klonopin and placebo in reduction from baseline in the number of full panic attacks was approximately 1 panic attack per week. At endpoint, 62% of patients receiving clonazepam were free of full panic attacks, compared to 37% of placebo-treated patients. Subgroup analyses did not indicate that there were any differences in treatment outcomes as a function of race or gender. INDICATIONS AND USAGE Seizure Disorders: Klonopin is useful alone or as an adjunct in the treatment of the Lennox-Gastaut syndrome (petit mal variant), akinetic and myoclonic seizures. In patients with absence seizures (petit mal) who have failed to respond to succinimides, Klonopin may be useful. Reference ID: 3398090 2 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda NDA 017533 Klonopin (clonazepam) tablets FDA Approved Labeling Text October 2013 In some studies, up to 30% of patients have shown a loss of anticonvulsant activity, often within 3 months of administration. In some cases, dosage adjustment may reestablish efficacy. Panic Disorder: Klonopin is indicated for the treatment of panic disorder, with or without agoraphobia, as defined in DSM-IV. Panic disorder is characterized by the occurrence of unexpected panic attacks and associated concern about having additional attacks, worry about the implications or consequences of the attacks, and/or a significant change in behavior related to the attacks. The efficacy of Klonopin was established in two 6- to 9-week trials in panic disorder patients whose diagnoses corresponded to the DSM-IIIR category of panic disorder (see CLINICAL PHARMACOLOGY: Clinical Trials). Panic disorder (DSM-IV) is characterized by recurrent unexpected panic attacks, ie, a discrete period of intense fear or discomfort in which four (or more) of the following symptoms develop abruptly and reach a peak within 10 minutes: (1) palpitations, pounding heart or accelerated heart rate; (2) sweating; (3) trembling or shaking; (4) sensations of shortness of breath or smothering; (5) feeling of choking; (6) chest pain or discomfort; (7) nausea or abdominal distress; (8) feeling dizzy, unsteady, lightheaded or faint; (9) derealization (feelings of unreality) or depersonalization (being detached from oneself); (10) fear of losing control; (11) fear of dying; (12) paresthesias (numbness or tingling sensations); (13) chills or hot flushes. The effectiveness of Klonopin in long-term use, that is, for more than 9 weeks, has not been systematically studied in controlled clinical trials. The physician who elects to use Klonopin for extended periods should periodically reevaluate the long-term usefulness of the drug for the individual patient (see DOSAGE AND ADMINISTRATION). CONTRAINDICATIONS Klonopin should not be used in patients with a history of sensitivity to benzodiazepines, nor in patients with clinical or biochemical evidence of significant liver disease. It may be used in patients with open angle glaucoma who are receiving appropriate therapy but is contraindicated in acute narrow angle glaucoma. WARNINGS Interference With Cognitive and Motor Performance: Since Klonopin produces CNS depression, patients receiving this drug should be cautioned against engaging in hazardous occupations requiring mental alertness, such as operating machinery or driving a motor vehicle. They should also be warned about the concomitant use of alcohol or other CNS-depressant drugs during Klonopin therapy (see PRECAUTIONS: Drug Interactions and Information for Patients). Suicidal Behavior and Ideation: Antiepileptic drugs (AEDs), including Klonopin, increase the risk of suicidal thoughts or behavior in patients taking these drugs for any indication. Patients treated with any AED for any indication should be monitored for the emergence or worsening of depression, suicidal thoughts or behavior, and/or any unusual changes in mood or behavior. Reference ID: 3398090 3 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda NDA 017533 Klonopin (clonazepam) tablets FDA Approved Labeling Text October 2013 Pooled analyses of 199 placebo-controlled clinical trials (mono- and adjunctive therapy) of 11 different AEDs showed that patients randomized to one of the AEDs had approximately twice the risk (adjusted Relative Risk 1.8, 95% CI:1.2, 2.7) of suicidal thinking or behavior compared to patients randomized to placebo. In these trials, which had a median treatment duration of 12 weeks, the estimated incidence rate of suicidal behavior or ideation among 27,863 AED-treated patients was 0.43% compared to 0.24% among 16,029 placebo-treated patients, representing an increase of approximately one case of suicidal thinking or behavior for every 530 patients treated. There were four suicides in drug-treated patients in the trials and none in placebo-treated patients, but the number is too small to allow any conclusion about drug effect on suicide. The increased risk of suicidal thoughts or behavior with AEDs was observed as early as one week after starting drug treatment with AEDs and persisted for the duration of treatment assessed. Because most trials included in the analysis did not extend beyond 24 weeks, the risk of suicidal thoughts or behavior beyond 24 weeks could not be assessed. The risk of suicidal thoughts or behavior was generally consistent among drugs in the data analyzed. The finding of increased risk with AEDs of varying mechanisms of action and across a range of indications suggests that the risk applies to all AEDs used for any indication. The risk did not vary substantially by age (5-100 years) in the clinical trials analyzed. Table 1 shows absolute and relative risk by indication for all evaluated AEDs. Table 1 Risk by Indication for Antiepileptic Drugs in the Pooled Analysis Indication Placebo Patients with Events Per 1000 Patients Drug Patients with Events Per 1000 Patients Relative Risk: Incidence of Events in Drug Patients/Incidence in Placebo Patients Risk Difference: Additional Drug Patients with Events per 1000 Patients Epilepsy Psychiatric Other Total 1.0 5.7 1.0 2.4 3.4 8.5 1.8 4.3 3.5 1.5 1.9 1.8 2.4 2.9 0.9 1.9 The relative risk for suicidal thoughts or behavior was higher in clinical trials for epilepsy than in clinical trials for psychiatric or other conditions, but the absolute risk differences were similar for the epilepsy and psychiatric indications. Anyone considering prescribing Klonopin or any other AED must balance the risk of suicidal thoughts or behavior with the risk of untreated illness. Epilepsy and many other illnesses for which AEDs are prescribed are themselves associated with morbidity and mortality and an increased risk of suicidal thoughts and behavior. Should suicidal thoughts and behavior emerge during treatment, the prescriber needs to consider whether the emergence of these symptoms in any given patient may be related to the illness being treated. Reference ID: 3398090 4 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda NDA 017533 Klonopin (clonazepam) tablets FDA Approved Labeling Text October 2013 Patients, their caregivers, and families should be informed that AEDs increase the risk of suicidal thoughts and behavior and should be advised of the need to be alert for the emergence or worsening of the signs and symptoms of depression, any unusual changes in mood or behavior, or the emergence of suicidal thoughts, behavior, or thoughts about self-harm. Behaviors of concern should be reported immediately to healthcare providers. Pregnancy Risks: Data from several sources raise concerns about the use of Klonopin during pregnancy. Animal Findings: In three studies in which Klonopin was administered orally to pregnant rabbits at doses of 0.2, 1, 5 or 10 mg/kg/day (low dose approximately 0.2 times the maximum recommended human dose of 20 mg/day for seizure disorders and equivalent to the maximum dose of 4 mg/day for panic disorder, on a mg/m2 basis) during the period of organogenesis, a similar pattern of malformations (cleft palate, open eyelid, fused sternebrae and limb defects) was observed in a low, non-dose-related incidence in exposed litters from all dosage groups. Reductions in maternal weight gain occurred at dosages of 5 mg/kg/day or greater and reduction in embryo-fetal growth occurred in one study at a dosage of 10 mg/kg/day. No adverse maternal or embryo-fetal effects were observed in mice and rats following administration during organogenesis of oral doses up to 15 mg/kg/day or 40 mg/kg/day, respectively (4 and 20 times the maximum recommended human dose of 20 mg/day for seizure disorders and 20 and 100 times the maximum dose of 4 mg/day for panic disorder, respectively, on a mg/m2 basis). General Concerns and Considerations About Anticonvulsants: Recent reports suggest an association between the use of anticonvulsant drugs by women with epilepsy and an elevated incidence of birth defects in children born to these women. Data are more extensive with respect to diphenylhydantoin and phenobarbital, but these are also the most commonly prescribed anticonvulsants; less systematic or anecdotal reports suggest a possible similar association with the use of all known anticonvulsant drugs. In children of women treated with drugs for epilepsy, reports suggesting an elevated incidence of birth defects cannot be regarded as adequate to prove a definite cause and effect relationship. There are intrinsic methodologic problems in obtaining adequate data on drug teratogenicity in humans; the possibility also exists that other factors (eg, genetic factors or the epileptic condition itself) may be more important than drug therapy in leading to birth defects. The great majority of mothers on anticonvulsant medication deliver normal infants. It is important to note that anticonvulsant drugs should not be discontinued in patients in whom the drug is administered to prevent seizures because of the strong possibility of precipitating status epilepticus with attendant hypoxia and threat to life. In individual cases where the severity and frequency of the seizure disorder are such that the removal of medication does not pose a serious threat to the patient, discontinuation of the drug may be considered prior to and during pregnancy; however, it cannot be said with any confidence that even mild seizures do not pose some hazards to the developing embryo or fetus. General Concerns About Benzodiazepines: An increased risk of congenital malformations associated with the use of benzodiazepine drugs has been suggested in several studies. Reference ID: 3398090 5 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda NDA 017533 Klonopin (clonazepam) tablets FDA Approved Labeling Text October 2013 There may also be non-teratogenic risks associated with the use of benzodiazepines during pregnancy. There have been reports of neonatal flaccidity, respiratory and feeding difficulties, and hypothermia in children born to mothers who have been receiving benzodiazepines late in pregnancy. In addition, children born to mothers receiving benzodiazepines late in pregnancy may be at some risk of experiencing withdrawal symptoms during the postnatal period. Advice Regarding the Use of Klonopin in Women of Childbearing Potential: In general, the use of Klonopin in women of childbearing potential, and more specifically during known pregnancy, should be considered only when the clinical situation warrants the risk to the fetus. The specific considerations addressed above regarding the use of anticonvulsants for epilepsy in women of childbearing potential should be weighed in treating or counseling these women. Because of experience with other members of the benzodiazepine class, Klonopin is assumed to be capable of causing an increased risk of congenital abnormalities when administered to a pregnant woman during the first trimester. Because use of these drugs is rarely a matter of urgency in the treatment of panic disorder, their use during the first trimester should almost always be avoided. The possibility that a woman of childbearing potential may be pregnant at the time of institution of therapy should be considered. If this drug is used during pregnancy, or if the patient becomes pregnant while taking this drug, the patient should be apprised of the potential hazard to the fetus. Patients should also be advised that if they become pregnant during therapy or intend to become pregnant, they should communicate with their physician about the desirability of discontinuing the drug. Withdrawal Symptoms: Withdrawal symptoms of the barbiturate type have occurred after the discontinuation of benzodiazepines (see DRUG ABUSE AND DEPENDENCE). PRECAUTIONS General: Worsening of Seizures: When used in patients in whom several different types of seizure disorders coexist, Klonopin may increase the incidence or precipitate the onset of generalized tonic-clonic seizures (grand mal). This may require the addition of appropriate anticonvulsants or an increase in their dosages. The concomitant use of valproic acid and Klonopin may produce absence status. Laboratory Testing During Long-Term Therapy: Periodic blood counts and liver function tests are advisable during long-term therapy with Klonopin. Risks of Abrupt Withdrawal: The abrupt withdrawal of Klonopin, particularly in those patients on long-term, high-dose therapy, may precipitate status epilepticus. Therefore, when discontinuing Klonopin, gradual withdrawal is essential. While Klonopin is being gradually withdrawn, the simultaneous substitution of another anticonvulsant may be indicated.

For current labeling information, please visit https://www.fda.gov/drugsatfda NDA 017533 Klonopin (clonazepam) tablets FDA Approved Labeling Text October 2013 Caution in Renally Impaired Patients: Metabolites of Klonopin are excreted by the kidneys; to avoid their excess accumulation, caution should be exercised in the administration of the drug to patients with impaired renal function. Hypersalivation: Klonopin may produce an increase in salivation. This should be considered before giving the drug to patients who have difficulty handling secretions. Because of this and the possibility of respiratory depression, Klonopin should be used with caution in patients with chronic respiratory diseases. Information for Patients: A Klonopin Medication Guide must be given to the patient each time Klonopin is dispensed, as required by law. Patients should be instructed to take Klonopin only as prescribed. Physicians are advised to discuss the following issues with patients for whom they prescribe Klonopin: Dose Changes: To assure the safe and effective use of benzodiazepines, patients should be informed that, since benzodiazepines may produce psychological and physical dependence, it is advisable that they consult with their physician before either increasing the dose or abruptly discontinuing this drug. Interference With Cognitive and Motor Performance: Because benzodiazepines have the potential to impair judgment, thinking or motor skills, patients should be cautioned about operating hazardous machinery, including automobiles, until they are reasonably certain that Klonopin therapy does not affect them adversely. Suicidal Thinking and Behavior: Patients, their caregivers, and families should be counseled that AEDs, including Klonopin, may increase the risk of suicidal thoughts and behavior and should be advised of the need to be alert for the emergence or worsening of symptoms of depression, any unusual changes in mood or behavior, or the emergence of suicidal thoughts, behavior, or thoughts about self-harm. Behaviors of concern should be reported immediately to healthcare providers. Pregnancy: Patients should be advised to notify their physician if they become pregnant or intend to become pregnant during therapy with Klonopin (see WARNINGS: Pregnancy Risks). Patients should be encouraged to enroll in the North American Antiepileptic Drug (NAAED) Pregnancy Registry if they become pregnant. This registry is collecting information about the safety of antiepileptic drugs during pregnancy. To enroll, patients can call the toll free number 1-888-233-2334 (see PRECAUTIONS: Pregnancy). Nursing: Patients should be advised not to breastfeed an infant if they are taking Klonopin. Concomitant Medication: Patients should be advised to inform their physicians if they are taking, or plan to take, any prescription or over-the-counter drugs, since there is a potential for interactions. Alcohol: Patients should be advised to avoid alcohol while taking Klonopin. Drug Interactions: Effect of Clonazepam on the Pharmacokinetics of Other Drugs: Clonazepam does not appear to alter the pharmacokinetics of phenytoin, carbamazepine Reference ID: 3398090 7 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda NDA 017533 Klonopin (clonazepam) tablets FDA Approved Labeling Text October 2013 or phenobarbital. The effect of clonazepam on the metabolism of other drugs has not been investigated. Effect of Other Drugs on the Pharmacokinetics of Clonazepam: Literature reports suggest that ranitidine, an agent that decreases stomach acidity, does not greatly alter clonazepam pharmacokinetics. In a study in which the 2 mg clonazepam orally disintegrating tablet was administered with and without propantheline (an anticholinergic agent with multiple effects on the GI tract) to healthy volunteers, the AUC of clonazepam was 10% lower and the Cmax of clonazepam was 20% lower when the orally disintegrating tablet was given with propantheline compared to when it was given alone. Fluoxetine does not affect the pharmacokinetics of clonazepam. Cytochrome P-450 inducers, such as phenytoin, carbamazepine and phenobarbital, induce clonazepam metabolism, causing an approximately 30% decrease in plasma clonazepam levels. Although clinical studies have not been performed, based on the involvement of the cytochrome P-450 3A family in clonazepam metabolism, inhibitors of this enzyme system, notably oral antifungal agents, should be used cautiously in patients receiving clonazepam. Pharmacodynamic Interactions: The CNS-depressant action of the benzodiazepine class of drugs may be potentiated by alcohol, narcotics, barbiturates, nonbarbiturate hypnotics, antianxiety agents, the phenothiazines, thioxanthene and butyrophenone classes of antipsychotic agents, monoamine oxidase inhibitors and the tricyclic antidepressants, and by other anticonvulsant drugs. Carcinogenesis, Mutagenesis, Impairment of Fertility: Carcinogenicity studies have not been conducted with clonazepam. The data currently available are not sufficient to determine the genotoxic potential of clonazepam. In a two-generation fertility study in which clonazepam was given orally to rats at 10 and 100 mg/kg/day (low dose approximately 5 times and 24 times the maximum recommended human dose of 20 mg/day for seizure disorder and 4 mg/day for panic disorder, respectively, on a mg/m2 basis), there was a decrease in the number of pregnancies and in the number of offspring surviving until weaning. Pregnancy: Teratogenic Effects: Pregnancy Category D (see WARNINGS: Pregnancy Risks). To provide information regarding the effects of in utero exposure to Klonopin, physicians are advised to recommend that pregnant patients taking Klonopin enroll in the NAAED Pregnancy Registry. This can be done by calling the toll free number 1-888-233-2334, and must be done by patients themselves. Information on this registry can also be found at the website http://www.aedpregnancyregistry.org/. Labor and Delivery: The effect of Klonopin on labor and delivery in humans has not been specifically studied; however, perinatal complications have been reported in Reference ID: 3398090 8 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda NDA 017533 Klonopin (clonazepam) tablets FDA Approved Labeling Text October 2013 children born to mothers who have been receiving benzodiazepines late in pregnancy, including findings suggestive of either excess benzodiazepine exposure or of withdrawal phenomena (see WARNINGS: Pregnancy Risks). Nursing Mothers: Mothers receiving Klonopin should not breastfeed their infants. Pediatric Use: Because of the possibility that adverse effects on physical or mental development could become apparent only after many years, a benefit-risk consideration of the long-term use of Klonopin is important in pediatric patients being treated for seizure disorder (see INDICATIONS AND USAGE and DOSAGE AND ADMINISTRATION). Safety and effectiveness in pediatric patients with panic disorder below the age of 18 have not been established. Geriatric Use: Clinical studies of Klonopin did not include sufficient numbers of subjects aged 65 and over to determine whether they respond differently from younger subjects. Other reported clinical experience has not identified differences in responses between the elderly and younger patients. In general, dose selection for an elderly patient should be cautious, usually starting at the low end of the dosing range, reflecting the greater frequency of decreased hepatic, renal, or cardiac function, and of concomitant disease or other drug therapy. Because clonazepam undergoes hepatic metabolism, it is possible that liver disease will impair clonazepam elimination. Metabolites of Klonopin are excreted by the kidneys; to avoid their excess accumulation, caution should be exercised in the administration of the drug to patients with impaired renal function. Because elderly patients are more likely to have decreased hepatic and/or renal function, care should be taken in dose selection, and it may be useful to assess hepatic and/or renal function at the time of dose selection. Sedating drugs may cause confusion and over-sedation in the elderly; elderly patients generally should be started on low doses of Klonopin and observed closely. ADVERSE REACTIONS The adverse experiences for Klonopin are provided separately for patients with seizure disorders and with panic disorder. Seizure Disorders: The most frequently occurring side effects of Klonopin are referable to CNS depression. Experience in treatment of seizures has shown that drowsiness has occurred in approximately 50% of patients and ataxia in approximately 30%. In some cases, these may diminish with time; behavior problems have been noted in approximately 25% of patients. Others, listed by system, are: Neurologic: Abnormal eye movements, aphonia, choreiform movements, coma, diplopia, dysarthria, dysdiadochokinesis, ‘‘glassy-eyed’’ appearance, headache, hemiparesis, hypotonia, nystagmus, respiratory depression, slurred speech, tremor, vertigo Psychiatric: Confusion, depression, amnesia, hallucinations, hysteria, increased libido, insomnia, psychosis (the behavior effects are more likely to occur in patients with a Reference ID: 3398090 9 This label may not be the latest approved by FDA.

The following paradoxical reactions have been observed: excitability, irritability, aggressive behavior, agitation, nervousness, hostility, anxiety, sleep disturbances, nightmares and vivid dreams Respiratory: Chest congestion, rhinorrhea, shortness of breath, hypersecretion in upper respiratory passages Cardiovascular: Palpitations Dermatologic: Hair loss, hirsutism, skin rash, ankle and facial edema Gastrointestinal: Anorexia, coated tongue, constipation, diarrhea, dry mouth, encopresis, gastritis, increased appetite, nausea, sore gums Genitourinary: Dysuria, enuresis, nocturia, urinary retention Musculoskeletal: Muscle weakness, pains Miscellaneous: Dehydration, general deterioration, fever, lymphadenopathy, weight loss or gain Hematopoietic: Anemia, leukopenia, thrombocytopenia, eosinophilia Hepatic: Hepatomegaly, transient elevations of serum transaminases and alkaline phosphatase Panic Disorder: Adverse events during exposure to Klonopin were obtained by spontaneous report and recorded by clinical investigators using terminology of their own choosing. Consequently, it is not possible to provide a meaningful estimate of the proportion of individuals experiencing adverse events without first grouping similar types of events into a smaller number of standardized event categories. In the tables and tabulations that follow, CIGY dictionary terminology has been used to classify reported adverse events, except in certain cases in which redundant terms were collapsed into more meaningful terms, as noted below. The stated frequencies of adverse events represent the proportion of individuals who experienced, at least once, a treatment-emergent adverse event of the type listed. An event was considered treatment-emergent if it occurred for the first time or worsened while receiving therapy following baseline evaluation. Adverse Findings Observed in Short-Term, Placebo-Controlled Trials: Adverse Events Associated With Discontinuation of Treatment: Overall, the incidence of discontinuation due to adverse events was 17% in Klonopin compared to 9% for placebo in the combined data of two 6- to 9-week trials. The most common events (≥1%) associated with discontinuation and a dropout rate twice or greater for Klonopin than that of placebo included the following: Reference ID: 3398090 10 This label may not be the latest approved by FDA.

Events reported in 1% or more of patients treated with Klonopin (doses ranging from 0.5 to 4 mg/day) and for which the incidence was greater than that in placebo-treated patients are included. The prescriber should be aware that the figures in Table 3 cannot be used to predict the incidence of side effects in the course of usual medical practice where patient characteristics and other factors differ from those that prevailed in the clinical trials. Similarly, the cited frequencies cannot be compared with figures obtained from other clinical investigations involving different treatments, uses and investigators. The cited figures, however, do provide the prescribing physician with some basis for estimating the relative contribution of drug and nondrug factors to the side effect incidence in the population studied.

Treatment-Emergent Depressive Symptoms: In the pool of two short-term placebo-controlled trials, adverse events classified under the preferred term “depression” were reported in 7% of Klonopin-treated patients compared to 1% of placebo-treated patients, without any clear pattern of dose relatedness. In these same trials, adverse events classified under the preferred term “depression” were reported as leading to discontinuation in 4% of Klonopin-treated patients compared to 1% of placebo-treated patients. While these findings are noteworthy, Hamilton Depression Rating Scale (HAM-D) data collected in these trials revealed a larger decline in HAM-D scores in the clonazepam group than the placebo group suggesting that clonazepam­ treated patients were not experiencing a worsening or emergence of clinical depression. Other Adverse Events Observed During the Premarketing Evaluation of Klonopin in Panic Disorder: Following is a list of modified CIGY terms that reflect treatment-emergent adverse events reported by patients treated with Klonopin at multiple doses during clinical trials. All reported events are included except those already listed in Table 3 or elsewhere in labeling, those events for which a drug cause was remote, those event terms which were so general as to be uninformative, and events reported only once and which did not have a substantial probability of being acutely life-threatening. It is important to emphasize that, although the events occurred during treatment with Klonopin, they were not necessarily caused by it. Events are further categorized by body system and listed in order of decreasing frequency. These adverse events were reported infrequently, which is defined as occurring in 1/100 to 1/1000 patients. Body as a Whole: weight increase, accident, weight decrease, wound, edema, fever, shivering, abrasions, ankle edema, edema foot, edema periorbital, injury, malaise, pain, cellulitis, inflammation localized Cardiovascular Disorders: chest pain, hypotension postural Reference ID: 3398090 14 This label may not be the latest approved by FDA.

Physical and Psychological Dependence: Withdrawal symptoms, similar in character to those noted with barbiturates and alcohol (eg, convulsions, psychosis, hallucinations, Reference ID: 3398090 15 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda NDA 017533 Klonopin (clonazepam) tablets FDA Approved Labeling Text October 2013 behavioral disorder, tremor, abdominal and muscle cramps) have occurred following abrupt discontinuance of clonazepam. The more severe withdrawal symptoms have usually been limited to those patients who received excessive doses over an extended period of time. Generally milder withdrawal symptoms (eg, dysphoria and insomnia) have been reported following abrupt discontinuance of benzodiazepines taken continuously at therapeutic levels for several months. Consequently, after extended therapy, abrupt discontinuation should generally be avoided and a gradual dosage tapering schedule followed (see DOSAGE AND ADMINISTRATION). Addiction-prone individuals (such as drug addicts or alcoholics) should be under careful surveillance when receiving clonazepam or other psychotropic agents because of the predisposition of such patients to habituation and dependence. Following the short-term treatment of patients with panic disorder in Studies 1 and 2 (see CLINICAL PHARMACOLOGY: Clinical Trials), patients were gradually withdrawn during a 7-week downward-titration (discontinuance) period. Overall, the discontinuance period was associated with good tolerability and a very modest clinical deterioration, without evidence of a significant rebound phenomenon. However, there are not sufficient data from adequate and well-controlled long-term clonazepam studies in patients with panic disorder to accurately estimate the risks of withdrawal symptoms and dependence that may be associated with such use. OVERDOSAGE Human Experience: Symptoms of clonazepam overdosage, like those produced by other CNS depressants, include somnolence, confusion, coma and diminished reflexes. Overdose Management: Treatment includes monitoring of respiration, pulse and blood pressure, general supportive measures and immediate gastric lavage. Intravenous fluids should be administered and an adequate airway maintained. Hypotension may be combated by the use of levarterenol or metaraminol. Dialysis is of no known value. Flumazenil, a specific benzodiazepine-receptor antagonist, is indicated for the complete or partial reversal of the sedative effects of benzodiazepines and may be used in situations when an overdose with a benzodiazepine is known or suspected. Prior to the administration of flumazenil, necessary measures should be instituted to secure airway, ventilation and intravenous access. Flumazenil is intended as an adjunct to, not as a substitute for, proper management of benzodiazepine overdose. Patients treated with flumazenil should be monitored for resedation, respiratory depression and other residual benzodiazepine effects for an appropriate period after treatment. The prescriber should be aware of a risk of seizure in association with flumazenil treatment, particularly in long-term benzodiazepine users and in cyclic antidepressant overdose. The complete flumazenil package insert, including CONTRAINDICATIONS, WARNINGS and PRECAUTIONS, should be consulted prior to use. Flumazenil is not indicated in patients with epilepsy who have been treated with benzodiazepines. Antagonism of the benzodiazepine effect in such patients may provoke seizures. Serious sequelae are rare unless other drugs or alcohol have been taken concomitantly. Reference ID: 3398090 16 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda NDA 017533 Klonopin (clonazepam) tablets FDA Approved Labeling Text October 2013 DOSAGE AND ADMINISTRATION Clonazepam is available as a tablet. The tablets should be administered with water by swallowing the tablet whole. Seizure Disorders: Adults: The initial dose for adults with seizure disorders should not exceed 1.5 mg/day divided into three doses. Dosage may be increased in increments of 0.5 to 1 mg every 3 days until seizures are adequately controlled or until side effects preclude any further increase. Maintenance dosage must be individualized for each patient depending upon response. Maximum recommended daily dose is 20 mg. The use of multiple anticonvulsants may result in an increase of depressant adverse effects. This should be considered before adding Klonopin to an existing anticonvulsant regimen. Pediatric Patients: Klonopin is administered orally. In order to minimize drowsiness, the initial dose for infants and children (up to 10 years of age or 30 kg of body weight) should be between 0.01 and 0.03 mg/kg/day but not to exceed 0.05 mg/kg/day given in two or three divided doses. Dosage should be increased by no more than 0.25 to 0.5 mg every third day until a daily maintenance dose of 0.1 to 0.2 mg/kg of body weight has been reached, unless seizures are controlled or side effects preclude further increase. Whenever possible, the daily dose should be divided into three equal doses. If doses are not equally divided, the largest dose should be given before retiring. Geriatric Patients: There is no clinical trial experience with Klonopin in seizure disorder patients 65 years of age and older. In general, elderly patients should be started on low doses of Klonopin and observed closely (see PRECAUTIONS: Geriatric Use). Panic Disorder: Adults: The initial dose for adults with panic disorder is 0.25 mg bid. An increase to the target dose for most patients of 1 mg/day may be made after 3 days. The recommended dose of 1 mg/day is based on the results from a fixed dose study in which the optimal effect was seen at 1 mg/day. Higher doses of 2, 3 and 4 mg/day in that study were less effective than the 1 mg/day dose and were associated with more adverse effects. Nevertheless, it is possible that some individual patients may benefit from doses of up to a maximum dose of 4 mg/day, and in those instances, the dose may be increased in increments of 0.125 to 0.25 mg bid every 3 days until panic disorder is controlled or until side effects make further increases undesired. To reduce the inconvenience of somnolence, administration of one dose at bedtime may be desirable. Treatment should be discontinued gradually, with a decrease of 0.125 mg bid every 3 days, until the drug is completely withdrawn. There is no body of evidence available to answer the question of how long the patient treated with clonazepam should remain on it. Therefore, the physician who elects to use Klonopin for extended periods should periodically reevaluate the long-term usefulness of the drug for the individual patient.

There may be new information. This information does not take the place of talking to your healthcare provider about your medical condition or treatment. KLONOPIN can cause serious side effects. Because stopping KLONOPIN suddenly can also cause serious problems, do not stop taking KLONOPIN without talking to your healthcare provider first. What is the most important information I should know about KLONOPIN? Do not stop taking KLONOPIN without first talking to your healthcare provider. Stopping KLONOPIN suddenly can cause serious problems. KLONOPIN can cause serious side effects, including: 1. KLONOPIN can slow your thinking and motor skills • Do not drive, operate heavy machinery, or do other dangerous activities until you know how KLONOPIN affects you. • Do not drink alcohol or take other drugs that may make you sleepy or dizzy while taking KLONOPIN until you talk to your healthcare provider. When taken with alcohol or drugs that cause sleepiness or dizziness, KLONOPIN may make your sleepiness or dizziness worse. 2. Like other antiepileptic drugs, KLONOPIN may cause suicidal thoughts or actions in a very small number of people, about 1 in 500. Call a healthcare provider right away if you have any of these symptoms, especially if they are new, worse, or worry you: • thoughts about suicide or dying • attempt to commit suicide • new or worse depression • new or worse anxiety • feeling agitated or restless • panic attacks • trouble sleeping (insomnia) • new or worse irritability • acting aggressive, being angry, or violent • acting on dangerous impulses • an extreme increase in activity and talking (mania) • other unusual changes in behavior or mood Reference ID: 3398090 1 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda 3. How can I watch for early symptoms of suicidal thoughts and actions? • Pay attention to any changes, especially sudden changes, in mood, behaviors, thoughts, or feelings. • Keep all follow-up visits with your healthcare provider as scheduled. Call your healthcare provider between visits as needed, especially if you are worried about symptoms. Suicidal thoughts or actions can be caused by things other than medicines. If you have suicidal thoughts or actions, your healthcare provider may check for other causes. Do not stop KLONOPIN without first talking to a healthcare provider. Stopping KLONOPIN suddenly can cause serious problems. Stopping KLONOPIN suddenly can cause seizures that will not stop (status epilepticus). KLONOPIN may harm your unborn or developing baby. • If you take KLONOPIN during pregnancy, your baby is at risk for serious birth defects. These defects can happen as early as in the first month of pregnancy, even before you know you are pregnant. Birth defects may occur even in children born to women who are not taking any medicines and do not have other risk factors. • Children born to mothers receiving benzodiazepine medications (including KLONOPIN) late in pregnancy may be at some risk of experiencing breathing problems, feeding problems, hypothermia, and withdrawal symptoms. • Tell your healthcare provider right away if you become pregnant while taking KLONOPIN. You and your healthcare provider should decide if you will take KLONOPIN while you are pregnant. • If you become pregnant while taking KLONOPIN, talk to your healthcare provider about registering with the North American Antiepileptic Drug Pregnancy Registry. You can register by calling 1-888-233-2334. The purpose of this registry is to collect information about the safety of antiepileptic drugs during pregnancy. • KLONOPIN can pass into breast milk. Talk to your healthcare provider about the best way to feed your baby if you take KLONOPIN. You and your healthcare provider should decide if you will take KLONOPIN or breast feed. You should not do both. 4. KLONOPIN can cause abuse and dependence. • Do not stop taking KLONOPIN all of a sudden. Stopping KLONOPIN suddenly can cause seizures that do not stop, hearing or seeing things that are not there (hallucinations), shaking, and stomach and muscle cramps.

Each tablet also contains lactose, magnesium 11 stearate, microcrystalline cellulose and corn starch, with the following colorants: 0.5 12 mg—FD&C Yellow No. 6 Lake; 1 mg—FD&C Blue No. 1 Lake and FD&C Blue No. 2 13 Lake. 14 Klonopin is also available as an orally disintegrating tablet containing 0.125 mg, 0.25 15 mg, 0.5 mg, 1 mg or 2 mg clonazepam. Each orally disintegrating tablet also contains 16 gelatin, mannitol, methylparaben sodium, propylparaben sodium and xanthan gum. 17 Chemically, clonazepam is 5-(2-chlorophenyl)-1,3-dihydro-7-nitro-2H-1,4­ 18 benzodiazepin-2-one. It is a light yellow crystalline powder. It has a molecular weight of 19 315.72 and the following structural formula: structural formula 20 21 CLINICAL PHARMACOLOGY 22 Pharmacodynamics: The precise mechanism by which clonazepam exerts its antiseizure 23 and antipanic effects is unknown, although it is believed to be related to its ability to 24 enhance the activity of gamma aminobutyric acid (GABA), the major inhibitory 25 neurotransmitter in the central nervous system. Convulsions produced in rodents by 26 pentylenetetrazol or, to a lesser extent, electrical stimulation are antagonized, as are 27 convulsions produced by photic stimulation in susceptible baboons. A taming effect in 28 aggressive primates, muscle weakness and hypnosis are also produced. In humans, 29 clonazepam is capable of suppressing the spike and wave discharge in absence seizures 30 (petit mal) and decreasing the frequency, amplitude, duration and spread of discharge in 31 minor motor seizures.

The absolute bioavailability of clonazepam is about 90%. Maximum 34 plasma concentrations of clonazepam are reached within 1 to 4 hours after oral 35 administration. Clonazepam is approximately 85% bound to plasma proteins. 36 Clonazepam is highly metabolized, with less than 2% unchanged clonazepam being 37 excreted in the urine. Biotransformation occurs mainly by reduction of the 7-nitro group 38 to the 4-amino derivative. This derivative can be acetylated, hydroxylated and 39 glucuronidated. Cytochrome P-450 including CYP3A, may play an important role in 40 clonazepam reduction and oxidation. The elimination half-life of clonazepam is typically 41 30 to 40 hours. Clonazepam pharmacokinetics are dose-independent throughout the 42 dosing range. There is no evidence that clonazepam induces its own metabolism or that 43 of other drugs in humans. 44 Pharmacokinetics in Demographic Subpopulations and in Disease States: Controlled 45 studies examining the influence of gender and age on clonazepam pharmacokinetics have 46 not been conducted, nor have the effects of renal or liver disease on clonazepam 47 pharmacokinetics been studied. Because clonazepam undergoes hepatic metabolism, it is 48 possible that liver disease will impair clonazepam elimination. Thus, caution should be 49 exercised when administering clonazepam to these patients. 50 Clinical Trials: Panic Disorder: The effectiveness of Klonopin in the treatment of panic 51 disorder was demonstrated in two double-blind, placebo-controlled studies of adult 52 outpatients who had a primary diagnosis of panic disorder (DSM-IIIR) with or without 53 agoraphobia. In these studies, Klonopin was shown to be significantly more effective 54 than placebo in treating panic disorder on change from baseline in panic attack frequency, 55 the Clinician’s Global Impression Severity of Illness Score and the Clinician’s Global 56 Impression Improvement Score. 57 Study 1 was a 9-week, fixed-dose study involving Klonopin doses of 0.5, 1, 2, 3 or 4 58 mg/day or placebo. This study was conducted in four phases: a 1-week placebo lead-in, a 59 3-week upward titration, a 6-week fixed dose and a 7-week discontinuance phase. A 60 significant difference from placebo was observed consistently only for the 1 mg/day 61 group. The difference between the 1 mg dose group and placebo in reduction from 62 baseline in the number of full panic attacks was approximately 1 panic attack per week. 63 At endpoint, 74% of patients receiving clonazepam 1 mg/day were free of full panic 64 attacks, compared to 56% of placebo-treated patients. 65 Study 2 was a 6-week, flexible-dose study involving Klonopin in a dose range of 0.5 to 4 66 mg/day or placebo. This study was conducted in three phases: a 1-week placebo lead-in, a 67 6-week optimal-dose and a 6-week discontinuance phase. The mean clonazepam dose 68 during the optimal dosing period was 2.3 mg/day. The difference between Klonopin and 69 placebo in reduction from baseline in the number of full panic attacks was approximately 70 1 panic attack per week. At endpoint, 62% of patients receiving clonazepam were free of 71 full panic attacks, compared to 37% of placebo-treated patients. 72 Subgroup analyses did not indicate that there were any differences in treatment outcomes 73 as a function of race or gender.

In 77 patients with absence seizures (petit mal) who have failed to respond to succinimides, 78 Klonopin may be useful. 79 In some studies, up to 30% of patients have shown a loss of anticonvulsant activity, often 80 within 3 months of administration. In some cases, dosage adjustment may reestablish 81 efficacy. 82 Panic Disorder: Klonopin is indicated for the treatment of panic disorder, with or 83 without agoraphobia, as defined in DSM-IV. Panic disorder is characterized by the 84 occurrence of unexpected panic attacks and associated concern about having additional 85 attacks, worry about the implications or consequences of the attacks, and/or a significant 86 change in behavior related to the attacks. 87 The efficacy of Klonopin was established in two 6- to 9-week trials in panic disorder 88 patients whose diagnoses corresponded to the DSM-IIIR category of panic disorder (see 89 CLINICAL PHARMACOLOGY: Clinical Trials). 90 Panic disorder (DSM-IV) is characterized by recurrent unexpected panic attacks, ie, a 91 discrete period of intense fear or discomfort in which four (or more) of the following 92 symptoms develop abruptly and reach a peak within 10 minutes: (1) palpitations, 93 pounding heart or accelerated heart rate; (2) sweating; (3) trembling or shaking; (4) 94 sensations of shortness of breath or smothering; (5) feeling of choking; (6) chest pain or 95 discomfort; (7) nausea or abdominal distress; (8) feeling dizzy, unsteady, lightheaded or 96 faint; (9) derealization (feelings of unreality) or depersonalization (being detached from 97 oneself); (10) fear of losing control; (11) fear of dying; (12) paresthesias (numbness or 98 tingling sensations); (13) chills or hot flushes. 99 The effectiveness of Klonopin in long-term use, that is, for more than 9 weeks, has not 100 been systematically studied in controlled clinical trials. The physician who elects to use 101 Klonopin for extended periods should periodically reevaluate the long-term usefulness of 102 the drug for the individual patient (see DOSAGE AND ADMINISTRATION). 103 CONTRAINDICATIONS 104 Klonopin should not be used in patients with a history of sensitivity to benzodiazepines, 105 nor in patients with clinical or biochemical evidence of significant liver disease. It may 106 be used in patients with open angle glaucoma who are receiving appropriate therapy but 107 is contraindicated in acute narrow angle glaucoma. 108 WARNINGS 109 Interference With Cognitive and Motor Performance: Since Klonopin produces CNS 110 depression, patients receiving this drug should be cautioned against engaging in 111 hazardous occupations requiring mental alertness, such as operating machinery or driving 112 a motor vehicle. They should also be warned about the concomitant use of alcohol or Reference ID: 3398090 3 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda Klonopin (clonazepam) tablets NDA 017533 Klonopin (clonazepam) wafers NDA 020813 FDA Approved Labeling Text October 2013 113 other CNS-depressant drugs during Klonopin therapy (see PRECAUTIONS: Drug 114 Interactions and Information for Patients). 115 Suicidal Behavior and Ideation: Antiepileptic drugs (AEDs), including Klonopin, 116 increase the risk of suicidal thoughts or behavior in patients taking these drugs for any 117 indication. Patients treated with any AED for any indication should be monitored for the 118 emergence or worsening of depression, suicidal thoughts or behavior, and/or any unusual 119 changes in mood or behavior. 120 Pooled analyses of 199 placebo-controlled clinical trials (mono- and adjunctive therapy) 121 of 11 different AEDs showed that patients randomized to one of the AEDs had 122 approximately twice the risk (adjusted Relative Risk 1.8, 95% CI:1.2, 2.7) of suicidal 123 thinking or behavior compared to patients randomized to placebo. In these trials, which 124 had a median treatment duration of 12 weeks, the estimated incidence rate of suicidal 125 behavior or ideation among 27,863 AED-treated patients was 0.43% compared to 0.24% 126 among 16,029 placebo-treated patients, representing an increase of approximately one 127 case of suicidal thinking or behavior for every 530 patients treated. There were four 128 suicides in drug-treated patients in the trials and none in placebo-treated patients, but the 129 number is too small to allow any conclusion about drug effect on suicide. 130 The increased risk of suicidal thoughts or behavior with AEDs was observed as early as 131 one week after starting drug treatment with AEDs and persisted for the duration of 132 treatment assessed. Because most trials included in the analysis did not extend beyond 24 133 weeks, the risk of suicidal thoughts or behavior beyond 24 weeks could not be assessed. 134 The risk of suicidal thoughts or behavior was generally consistent among drugs in the 135 data analyzed. The finding of increased risk with AEDs of varying mechanisms of action 136 and across a range of indications suggests that the risk applies to all AEDs used for any 137 indication. The risk did not vary substantially by age (5-100 years) in the clinical trials 138 analyzed. 139 Table 1 shows absolute and relative risk by indication for all evaluated AEDs. 140 Table 1 Risk by Indication for Antiepileptic Drugs in the Pooled 141 Analysis Indication Placebo Patients with Events Per 1000 Patients Drug Patients with Events Per 1000 Patients Relative Risk: Incidence of Events in Drug Patients/Incidence in Placebo Patients Risk Difference: Additional Drug Patients with Events per 1000 Patients Epilepsy Psychiatric Other Total 1.0 5.7 1.0 2.4 3.4 8.5 1.8 4.3 3.5 1.5 1.9 1.8 2.4 2.9 0.9 1.9 142 143 The relative risk for suicidal thoughts or behavior was higher in clinical trials for epilepsy 144 than in clinical trials for psychiatric or other conditions, but the absolute risk differences 145 were similar for the epilepsy and psychiatric indications.

Epilepsy and many other 148 illnesses for which AEDs are prescribed are themselves associated with morbidity and 149 mortality and an increased risk of suicidal thoughts and behavior. Should suicidal 150 thoughts and behavior emerge during treatment, the prescriber needs to consider whether 151 the emergence of these symptoms in any given patient may be related to the illness being 152 treated. 153 Patients, their caregivers, and families should be informed that AEDs increase the risk of 154 suicidal thoughts and behavior and should be advised of the need to be alert for the 155 emergence or worsening of the signs and symptoms of depression, any unusual changes 156 in mood or behavior, or the emergence of suicidal thoughts, behavior, or thoughts about 157 self-harm. Behaviors of concern should be reported immediately to healthcare providers. 158 Pregnancy Risks: Data from several sources raise concerns about the use of Klonopin 159 during pregnancy. 160 Animal Findings: In three studies in which Klonopin was administered orally to pregnant 161 rabbits at doses of 0.2, 1, 5 or 10 mg/kg/day (low dose approximately 0.2 times the 162 163 maximum recommended human dose of 20 mg/day for seizure disorders and equivalent to the maximum dose of 4 mg/day for panic disorder, on a mg/m2 basis) during the period 164 of organogenesis, a similar pattern of malformations (cleft palate, open eyelid, fused 165 sternebrae and limb defects) was observed in a low, non-dose-related incidence in 166 exposed litters from all dosage groups. Reductions in maternal weight gain occurred at 167 dosages of 5 mg/kg/day or greater and reduction in embryo-fetal growth occurred in one 168 study at a dosage of 10 mg/kg/day. No adverse maternal or embryo-fetal effects were 169 observed in mice and rats following administration during organogenesis of oral doses up 170 to 15 mg/kg/day or 40 mg/kg/day, respectively (4 and 20 times the maximum 171 172 recommended human dose of 20 mg/day for seizure disorders and 20 and 100 times the maximum dose of 4 mg/day for panic disorder, respectively, on a mg/m2 basis). 173 General Concerns and Considerations About Anticonvulsants: Recent reports suggest an 174 association between the use of anticonvulsant drugs by women with epilepsy and an 175 elevated incidence of birth defects in children born to these women. Data are more 176 extensive with respect to diphenylhydantoin and phenobarbital, but these are also the 177 most commonly prescribed anticonvulsants; less systematic or anecdotal reports suggest a 178 possible similar association with the use of all known anticonvulsant drugs. 179 In children of women treated with drugs for epilepsy, reports suggesting an elevated 180 incidence of birth defects cannot be regarded as adequate to prove a definite cause and 181 effect relationship. There are intrinsic methodologic problems in obtaining adequate data 182 on drug teratogenicity in humans; the possibility also exists that other factors (eg, genetic 183 factors or the epileptic condition itself) may be more important than drug therapy in 184 leading to birth defects. The great majority of mothers on anticonvulsant medication 185 deliver normal infants. It is important to note that anticonvulsant drugs should not be 186 discontinued in patients in whom the drug is administered to prevent seizures because of 187 the strong possibility of precipitating status epilepticus with attendant hypoxia and threat Reference ID: 3398090 5 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda Klonopin (clonazepam) tablets NDA 017533 Klonopin (clonazepam) wafers NDA 020813 FDA Approved Labeling Text October 2013 188 to life. In individual cases where the severity and frequency of the seizure disorder are 189 such that the removal of medication does not pose a serious threat to the patient, 190 discontinuation of the drug may be considered prior to and during pregnancy; however, it 191 cannot be said with any confidence that even mild seizures do not pose some hazards to 192 the developing embryo or fetus. 193 General Concerns About Benzodiazepines: An increased risk of congenital 194 malformations associated with the use of benzodiazepine drugs has been suggested in 195 several studies. 196 There may also be non-teratogenic risks associated with the use of benzodiazepines 197 during pregnancy. There have been reports of neonatal flaccidity, respiratory and feeding 198 difficulties, and hypothermia in children born to mothers who have been receiving 199 benzodiazepines late in pregnancy. In addition, children born to mothers receiving 200 benzodiazepines late in pregnancy may be at some risk of experiencing withdrawal 201 symptoms during the postnatal period. 202 Advice Regarding the Use of Klonopin in Women of Childbearing Potential: In general, 203 the use of Klonopin in women of childbearing potential, and more specifically during 204 known pregnancy, should be considered only when the clinical situation warrants the risk 205 to the fetus. 206 The specific considerations addressed above regarding the use of anticonvulsants for 207 epilepsy in women of childbearing potential should be weighed in treating or counseling 208 these women. 209 Because of experience with other members of the benzodiazepine class, Klonopin is 210 assumed to be capable of causing an increased risk of congenital abnormalities when 211 administered to a pregnant woman during the first trimester. Because use of these drugs 212 is rarely a matter of urgency in the treatment of panic disorder, their use during the first 213 trimester should almost always be avoided. The possibility that a woman of childbearing 214 potential may be pregnant at the time of institution of therapy should be considered. If 215 this drug is used during pregnancy, or if the patient becomes pregnant while taking this 216 drug, the patient should be apprised of the potential hazard to the fetus. Patients should 217 also be advised that if they become pregnant during therapy or intend to become 218 pregnant, they should communicate with their physician about the desirability of 219 discontinuing the drug. 220 Withdrawal Symptoms: Withdrawal symptoms of the barbiturate type have occurred 221 after the discontinuation of benzodiazepines (see DRUG ABUSE AND DEPENDENCE). 222 PRECAUTIONS 223 General: Worsening of Seizures: When used in patients in whom several different types 224 of seizure disorders coexist, Klonopin may increase the incidence or precipitate the onset 225 of generalized tonic-clonic seizures (grand mal). This may require the addition of 226 appropriate anticonvulsants or an increase in their dosages. The concomitant use of 227 valproic acid and Klonopin may produce absence status.

For current labeling information, please visit https://www.fda.gov/drugsatfda Klonopin (clonazepam) tablets NDA 017533 Klonopin (clonazepam) wafers NDA 020813 FDA Approved Labeling Text October 2013 228 Laboratory Testing During Long-Term Therapy: Periodic blood counts and liver function 229 tests are advisable during long-term therapy with Klonopin. 230 Risks of Abrupt Withdrawal: The abrupt withdrawal of Klonopin, particularly in those 231 patients on long-term, high-dose therapy, may precipitate status epilepticus. Therefore, 232 when discontinuing Klonopin, gradual withdrawal is essential. While Klonopin is being 233 gradually withdrawn, the simultaneous substitution of another anticonvulsant may be 234 indicated. 235 Caution in Renally Impaired Patients: Metabolites of Klonopin are excreted by the 236 kidneys; to avoid their excess accumulation, caution should be exercised in the 237 administration of the drug to patients with impaired renal function. 238 Hypersalivation: Klonopin may produce an increase in salivation. This should be 239 considered before giving the drug to patients who have difficulty handling secretions. 240 Because of this and the possibility of respiratory depression, Klonopin should be used 241 with caution in patients with chronic respiratory diseases. 242 Information for Patients: A Klonopin Medication Guide must be given to the patient 243 each time Klonopin is dispensed, as required by law. Patients should be instructed to take 244 Klonopin only as prescribed. Physicians are advised to discuss the following issues with 245 patients for whom they prescribe Klonopin: 246 Dose Changes: To assure the safe and effective use of benzodiazepines, patients should 247 be informed that, since benzodiazepines may produce psychological and physical 248 dependence, it is advisable that they consult with their physician before either increasing 249 the dose or abruptly discontinuing this drug. 250 Interference With Cognitive and Motor Performance: Because benzodiazepines have the 251 potential to impair judgment, thinking or motor skills, patients should be cautioned about 252 operating hazardous machinery, including automobiles, until they are reasonably certain 253 that Klonopin therapy does not affect them adversely. 254 Suicidal Thinking and Behavior: Patients, their caregivers, and families should be 255 counseled that AEDs, including Klonopin, may increase the risk of suicidal thoughts and 256 behavior and should be advised of the need to be alert for the emergence or worsening of 257 symptoms of depression, any unusual changes in mood or behavior, or the emergence of 258 suicidal thoughts, behavior, or thoughts about self-harm. Behaviors of concern should be 259 reported immediately to healthcare providers. 260 Pregnancy: Patients should be advised to notify their physician if they become pregnant 261 or intend to become pregnant during therapy with Klonopin (see WARNINGS: 262 Pregnancy Risks). Patients should be encouraged to enroll in the North American 263 Antiepileptic Drug (NAAED) Pregnancy Registry if they become pregnant. This registry 264 is collecting information about the safety of antiepileptic drugs during pregnancy. To 265 enroll, patients can call the toll free number 1-888-233-2334 (see PRECAUTIONS: 266 Pregnancy). Reference ID: 3398090 7 This label may not be the latest approved by FDA.

The effect of clonazepam on the metabolism of other drugs has not 276 been investigated. 277 Effect of Other Drugs on the Pharmacokinetics of Clonazepam: Literature reports suggest 278 that ranitidine, an agent that decreases stomach acidity, does not greatly alter clonazepam 279 pharmacokinetics. 280 In a study in which the 2 mg clonazepam orally disintegrating tablet was administered 281 with and without propantheline (an anticholinergic agent with multiple effects on the GI 282 tract) to healthy volunteers, the AUC of clonazepam was 10% lower and the Cmax of 283 clonazepam was 20% lower when the orally disintegrating tablet was given with 284 propantheline compared to when it was given alone. 285 Fluoxetine does not affect the pharmacokinetics of clonazepam. Cytochrome P-450 286 inducers, such as phenytoin, carbamazepine and phenobarbital, induce clonazepam 287 metabolism, causing an approximately 30% decrease in plasma clonazepam levels. 288 Although clinical studies have not been performed, based on the involvement of the 289 cytochrome P-450 3A family in clonazepam metabolism, inhibitors of this enzyme 290 system, notably oral antifungal agents, should be used cautiously in patients receiving 291 clonazepam. 292 Pharmacodynamic Interactions: The CNS-depressant action of the benzodiazepine class 293 of drugs may be potentiated by alcohol, narcotics, barbiturates, nonbarbiturate hypnotics, 294 antianxiety agents, the phenothiazines, thioxanthene and butyrophenone classes of 295 antipsychotic agents, monoamine oxidase inhibitors and the tricyclic antidepressants, and 296 by other anticonvulsant drugs. 297 Carcinogenesis, Mutagenesis, Impairment of Fertility: Carcinogenicity studies have not 298 been conducted with clonazepam. 299 The data currently available are not sufficient to determine the genotoxic potential of 300 clonazepam. 301 In a two-generation fertility study in which clonazepam was given orally to rats at 10 and 302 100 mg/kg/day (low dose approximately 5 times and 24 times the maximum 303 304 recommended human dose of 20 mg/day for seizure disorder and 4 mg/day for panic disorder, respectively, on a mg/m2 basis), there was a decrease in the number of 305 pregnancies and in the number of offspring surviving until weaning.

This can be done by calling the toll free number 1-888-233-2334, 311 and must be done by patients themselves. Information on this registry can also be found 312 at the website http://www.aedpregnancyregistry.org/. 313 Labor and Delivery: The effect of Klonopin on labor and delivery in humans has not 314 been specifically studied; however, perinatal complications have been reported in 315 children born to mothers who have been receiving benzodiazepines late in pregnancy, 316 including findings suggestive of either excess benzodiazepine exposure or of withdrawal 317 phenomena (see WARNINGS: Pregnancy Risks). 318 Nursing Mothers: Mothers receiving Klonopin should not breastfeed their infants. 319 Pediatric Use: Because of the possibility that adverse effects on physical or mental 320 development could become apparent only after many years, a benefit-risk consideration 321 of the long-term use of Klonopin is important in pediatric patients being treated for 322 seizure disorder (see INDICATIONS AND USAGE and DOSAGE AND 323 ADMINISTRATION). 324 Safety and effectiveness in pediatric patients with panic disorder below the age of 18 325 have not been established. 326 Geriatric Use: Clinical studies of Klonopin did not include sufficient numbers of subjects 327 aged 65 and over to determine whether they respond differently from younger subjects. 328 Other reported clinical experience has not identified differences in responses between the 329 elderly and younger patients. In general, dose selection for an elderly patient should be 330 cautious, usually starting at the low end of the dosing range, reflecting the greater 331 frequency of decreased hepatic, renal, or cardiac function, and of concomitant disease or 332 other drug therapy. 333 Because clonazepam undergoes hepatic metabolism, it is possible that liver disease will 334 impair clonazepam elimination. Metabolites of Klonopin are excreted by the kidneys; to 335 avoid their excess accumulation, caution should be exercised in the administration of the 336 drug to patients with impaired renal function. Because elderly patients are more likely to 337 have decreased hepatic and/or renal function, care should be taken in dose selection, and 338 it may be useful to assess hepatic and/or renal function at the time of dose selection. 339 Sedating drugs may cause confusion and over-sedation in the elderly; elderly patients 340 generally should be started on low doses of Klonopin and observed closely. 341 ADVERSE REACTIONS 342 The adverse experiences for Klonopin are provided separately for patients with seizure 343 disorders and with panic disorder.

Experience in treatment of seizures has shown that drowsiness has 346 occurred in approximately 50% of patients and ataxia in approximately 30%. In some 347 cases, these may diminish with time; behavior problems have been noted in 348 approximately 25% of patients. Others, listed by system, are: 349 Neurologic: Abnormal eye movements, aphonia, choreiform movements, coma, diplopia, 350 dysarthria, dysdiadochokinesis, ‘‘glassy-eyed’’ appearance, headache, hemiparesis, 351 hypotonia, nystagmus, respiratory depression, slurred speech, tremor, vertigo 352 Psychiatric: Confusion, depression, amnesia, hallucinations, hysteria, increased libido, 353 insomnia, psychosis (the behavior effects are more likely to occur in patients with a 354 history of psychiatric disturbances). The following paradoxical reactions have been 355 observed: excitability, irritability, aggressive behavior, agitation, nervousness, hostility, 356 anxiety, sleep disturbances, nightmares and vivid dreams 357 Respiratory: Chest congestion, rhinorrhea, shortness of breath, hypersecretion in upper 358 respiratory passages 359 Cardiovascular: Palpitations 360 Dermatologic: Hair loss, hirsutism, skin rash, ankle and facial edema 361 Gastrointestinal: Anorexia, coated tongue, constipation, diarrhea, dry mouth, encopresis, 362 gastritis, increased appetite, nausea, sore gums 363 Genitourinary: Dysuria, enuresis, nocturia, urinary retention 364 Musculoskeletal: Muscle weakness, pains 365 Miscellaneous: Dehydration, general deterioration, fever, lymphadenopathy, weight loss 366 or gain 367 Hematopoietic: Anemia, leukopenia, thrombocytopenia, eosinophilia 368 Hepatic: Hepatomegaly, transient elevations of serum transaminases and alkaline 369 phosphatase 370 Panic Disorder: Adverse events during exposure to Klonopin were obtained by 371 spontaneous report and recorded by clinical investigators using terminology of their own 372 choosing. Consequently, it is not possible to provide a meaningful estimate of the 373 proportion of individuals experiencing adverse events without first grouping similar types 374 of events into a smaller number of standardized event categories. In the tables and 375 tabulations that follow, CIGY dictionary terminology has been used to classify reported 376 adverse events, except in certain cases in which redundant terms were collapsed into 377 more meaningful terms, as noted below. 378 The stated frequencies of adverse events represent the proportion of individuals who 379 experienced, at least once, a treatment-emergent adverse event of the type listed.

The most 388 common events (≥1%) associated with discontinuation and a dropout rate twice or greater 389 for Klonopin than that of placebo included the following: 390 Table 2 Most Common Adverse Events (≥1%) Associated with 391 Discontinuation of Treatment Adverse Event Klonopin (N=574) Placebo (N=294) Somnolence 7% 1% Depression 4% 1% Dizziness 1% <1% Nervousness 1% 0% Ataxia 1% 0% Intellectual Ability Reduced 1% 0% 392 Adverse Events Occurring at an Incidence of 1% or More Among Klonopin-Treated 393 Patients: 394 Table 3 enumerates the incidence, rounded to the nearest percent, of treatment-emergent 395 adverse events that occurred during acute therapy of panic disorder from a pool of two 6­ 396 to 9-week trials. Events reported in 1% or more of patients treated with Klonopin (doses 397 ranging from 0.5 to 4 mg/day) and for which the incidence was greater than that in 398 placebo-treated patients are included. 399 The prescriber should be aware that the figures in Table 3 cannot be used to predict the 400 incidence of side effects in the course of usual medical practice where patient 401 characteristics and other factors differ from those that prevailed in the clinical trials. 402 Similarly, the cited frequencies cannot be compared with figures obtained from other 403 clinical investigations involving different treatments, uses and investigators. The cited 404 figures, however, do provide the prescribing physician with some basis for estimating the 405 relative contribution of drug and nondrug factors to the side effect incidence in the 406 population studied. 407 Table 3 Treatment-Emergent Adverse Event Incidence in 6- to 9­ 408 Week Placebo-Controlled Clinical Trials* Clonazepam Maximum Daily Dose Reference ID: 3398090 11 This label may not be the latest approved by FDA.

In these 424 same trials, adverse events classified under the preferred term “depression” were reported 425 as leading to discontinuation in 4% of Klonopin-treated patients compared to 1% of 426 placebo-treated patients. While these findings are noteworthy, Hamilton Depression 427 Rating Scale (HAM-D) data collected in these trials revealed a larger decline in HAM-D 428 scores in the clonazepam group than the placebo group suggesting that clonazepam­ 429 treated patients were not experiencing a worsening or emergence of clinical depression. 430 Other Adverse Events Observed During the Premarketing Evaluation of Klonopin in 431 Panic Disorder: 432 Following is a list of modified CIGY terms that reflect treatment-emergent adverse 433 events reported by patients treated with Klonopin at multiple doses during clinical trials. 434 All reported events are included except those already listed in Table 3 or elsewhere in 435 labeling, those events for which a drug cause was remote, those event terms which were 436 so general as to be uninformative, and events reported only once and which did not have 437 a substantial probability of being acutely life-threatening. It is important to emphasize 438 that, although the events occurred during treatment with Klonopin, they were not 439 necessarily caused by it. 440 Events are further categorized by body system and listed in order of decreasing 441 frequency. These adverse events were reported infrequently, which is defined as 442 occurring in 1/100 to 1/1000 patients. 443 Body as a Whole: weight increase, accident, weight decrease, wound, edema, fever, 444 shivering, abrasions, ankle edema, edema foot, edema periorbital, injury, malaise, pain, 445 cellulitis, inflammation localized 446 Cardiovascular Disorders: chest pain, hypotension postural Reference ID: 3398090 14 This label may not be the latest approved by FDA.

The more severe withdrawal symptoms have 484 usually been limited to those patients who received excessive doses over an extended 485 period of time. Generally milder withdrawal symptoms (eg, dysphoria and insomnia) 486 have been reported following abrupt discontinuance of benzodiazepines taken 487 continuously at therapeutic levels for several months. Consequently, after extended 488 therapy, abrupt discontinuation should generally be avoided and a gradual dosage 489 tapering schedule followed (see DOSAGE AND ADMINISTRATION). Addiction-prone 490 individuals (such as drug addicts or alcoholics) should be under careful surveillance when 491 receiving clonazepam or other psychotropic agents because of the predisposition of such 492 patients to habituation and dependence. 493 Following the short-term treatment of patients with panic disorder in Studies 1 and 2 (see 494 CLINICAL PHARMACOLOGY: Clinical Trials), patients were gradually withdrawn 495 during a 7-week downward-titration (discontinuance) period. Overall, the discontinuance 496 period was associated with good tolerability and a very modest clinical deterioration, 497 without evidence of a significant rebound phenomenon. However, there are not sufficient 498 data from adequate and well-controlled long-term clonazepam studies in patients with 499 panic disorder to accurately estimate the risks of withdrawal symptoms and dependence 500 that may be associated with such use. 501 OVERDOSAGE 502 Human Experience: Symptoms of clonazepam overdosage, like those produced by other 503 CNS depressants, include somnolence, confusion, coma and diminished reflexes. 504 Overdose Management: Treatment includes monitoring of respiration, pulse and blood 505 pressure, general supportive measures and immediate gastric lavage. Intravenous fluids 506 should be administered and an adequate airway maintained. Hypotension may be 507 combated by the use of levarterenol or metaraminol. Dialysis is of no known value. 508 Flumazenil, a specific benzodiazepine-receptor antagonist, is indicated for the complete 509 or partial reversal of the sedative effects of benzodiazepines and may be used in 510 situations when an overdose with a benzodiazepine is known or suspected. Prior to the 511 administration of flumazenil, necessary measures should be instituted to secure airway, 512 ventilation and intravenous access. Flumazenil is intended as an adjunct to, not as a 513 substitute for, proper management of benzodiazepine overdose. Patients treated with 514 flumazenil should be monitored for resedation, respiratory depression and other residual 515 benzodiazepine effects for an appropriate period after treatment. The prescriber should 516 be aware of a risk of seizure in association with flumazenil treatment, particularly in 517 long-term benzodiazepine users and in cyclic antidepressant overdose. The complete 518 flumazenil package insert, including CONTRAINDICATIONS, WARNINGS and 519 PRECAUTIONS, should be consulted prior to use.

Antagonism of the benzodiazepine effect in such patients may 522 provoke seizures. 523 Serious sequelae are rare unless other drugs or alcohol have been taken concomitantly. 524 DOSAGE AND ADMINISTRATION 525 Clonazepam is available as a tablet or an orally disintegrating tablet (wafer). The tablets 526 should be administered with water by swallowing the tablet whole. The orally 527 disintegrating tablet should be administered as follows: After opening the pouch, peel 528 back the foil on the blister. Do not push tablet through foil. Immediately upon opening 529 the blister, using dry hands, remove the tablet and place it in the mouth. Tablet 530 disintegration occurs rapidly in saliva so it can be easily swallowed with or without 531 water. 532 533 Seizure Disorders: Adults: The initial dose for adults with seizure disorders should not 534 exceed 1.5 mg/day divided into three doses. Dosage may be increased in increments of 535 0.5 to 1 mg every 3 days until seizures are adequately controlled or until side effects 536 preclude any further increase. Maintenance dosage must be individualized for each 537 patient depending upon response. Maximum recommended daily dose is 20 mg. 538 The use of multiple anticonvulsants may result in an increase of depressant adverse 539 effects. This should be considered before adding Klonopin to an existing anticonvulsant 540 regimen. 541 Pediatric Patients: Klonopin is administered orally. In order to minimize drowsiness, the 542 initial dose for infants and children (up to 10 years of age or 30 kg of body weight) 543 should be between 0.01 and 0.03 mg/kg/day but not to exceed 0.05 mg/kg/day given in 544 two or three divided doses. Dosage should be increased by no more than 0.25 to 0.5 mg 545 every third day until a daily maintenance dose of 0.1 to 0.2 mg/kg of body weight has 546 been reached, unless seizures are controlled or side effects preclude further increase. 547 Whenever possible, the daily dose should be divided into three equal doses. If doses are 548 not equally divided, the largest dose should be given before retiring. 549 Geriatric Patients: There is no clinical trial experience with Klonopin in seizure disorder 550 patients 65 years of age and older. In general, elderly patients should be started on low 551 doses of Klonopin and observed closely (see PRECAUTIONS: Geriatric Use). 552 Panic Disorder: Adults: The initial dose for adults with panic disorder is 0.25 mg bid. An 553 increase to the target dose for most patients of 1 mg/day may be made after 3 days. The 554 recommended dose of 1 mg/day is based on the results from a fixed dose study in which 555 the optimal effect was seen at 1 mg/day. Higher doses of 2, 3 and 4 mg/day in that study 556 were less effective than the 1 mg/day dose and were associated with more adverse 557 effects. Nevertheless, it is possible that some individual patients may benefit from doses 558 of up to a maximum dose of 4 mg/day, and in those instances, the dose may be increased 559 in increments of 0.125 to 0.25 mg bid every 3 days until panic disorder is controlled or Reference ID: 3398090 17 This label may not be the latest approved by FDA.

To reduce the inconvenience of 561 somnolence, administration of one dose at bedtime may be desirable. 562 Treatment should be discontinued gradually, with a decrease of 0.125 mg bid every 563 3 days, until the drug is completely withdrawn. 564 There is no body of evidence available to answer the question of how long the patient 565 treated with clonazepam should remain on it. Therefore, the physician who elects to use 566 Klonopin for extended periods should periodically reevaluate the long-term usefulness of 567 the drug for the individual patient. 568 Pediatric Patients: There is no clinical trial experience with Klonopin in panic disorder 569 patients under 18 years of age. 570 Geriatric Patients: There is no clinical trial experience with Klonopin in panic disorder 571 patients 65 years of age and older. In general, elderly patients should be started on low 572 doses of Klonopin and observed closely (see PRECAUTIONS: Geriatric Use). 573 HOW SUPPLIED 574 Klonopin tablets are available as scored tablets with a K-shaped perforation—0.5 mg, 575 orange (NDC 0004-0068-01); and unscored tablets with a K-shaped perforation—1 mg, 576 blue (NDC 0004-0058-01); 2 mg, white (NDC 0004-0098-01)—bottles of 100. 577 Imprint on tablets: usage illustration 578 0.5 mg — 1/2 KLONOPIN (front) 579 ROCHE (scored side) 580 1 mg — 1 KLONOPIN (front) 581 ROCHE (reverse side) usage illustration 582 2 mg — 2 KLONOPIN (front) 583 ROCHE (reverse side) usage illustration 584 Klonopin Wafers (clonazepam orally disintegrating tablets) are white, round and 585 debossed with the tablet strength expressed as a fraction or whole number (1/8, 1/4, 1/2, 586 1, or 2).

If 48 you have suicidal thoughts or actions, your healthcare provider may check 49 for other causes. 50 Do not stop KLONOPIN without first talking to a healthcare provider. 51 Stopping KLONOPIN suddenly can cause serious problems. Stopping 52 KLONOPIN suddenly can cause seizures that will not stop (status 53 epilepticus). 54 3. KLONOPIN may harm your unborn or developing baby. 55 • If you take KLONOPIN during pregnancy, your baby is at risk for serious 56 birth defects. These defects can happen as early as in the first month of 57 pregnancy, even before you know you are pregnant. Birth defects may 58 occur even in children born to women who are not taking any medicines 59 and do not have other risk factors. 60 • Children born to mothers receiving benzodiazepine medications (including 61 KLONOPIN) late in pregnancy may be at some risk of experiencing 62 breathing problems, feeding problems, hypothermia, and withdrawal 63 symptoms. 64 • Tell your healthcare provider right away if you become pregnant while 65 taking KLONOPIN. You and your healthcare provider should decide if 66 you will take KLONOPIN while you are pregnant. 67 • If you become pregnant while taking KLONOPIN, talk to your healthcare 68 provider about registering with the North American Antiepileptic Drug 69 Pregnancy Registry. You can register by calling 1-888-233-2334. The 70 purpose of this registry is to collect information about the safety of 71 antiepileptic drugs during pregnancy. 72 • KLONOPIN can pass into breast milk. Talk to your healthcare provider 73 about the best way to feed your baby if you take KLONOPIN. You and 74 your healthcare provider should decide if you will take KLONOPIN or 75 breast feed. You should not do both. 76 4. KLONOPIN can cause abuse and dependence. Reference ID: 3398090 2 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda 77 • Do not stop taking KLONOPIN all of a sudden. Stopping KLONOPIN 78 suddenly can cause seizures that do not stop, hearing or seeing things that 79 are not there (hallucinations), shaking, and stomach and muscle cramps. 80 o Talk to your doctor about slowly stopping KLONOPIN to avoid 81 getting sick with withdrawal symptoms. 82 o Physical dependence is not the same as drug addiction. Your 83 healthcare provider can tell you more about the differences 84 between physical dependence and drug addiction. 85 KLONOPIN is a federally controlled substance (C-IV) because it can be 86 abused or lead to dependence. Keep KLONOPIN in a safe place to prevent 87 misuse and abuse. Selling or giving away KLONOPIN may harm others, and 88 is against the law.

SINEMET ® (carbidopa levodopa) Tablets DESCRIPTION SINEMET® (carbidopa levodopa) is a combination of carbidopa and levodopa for the treatment of Parkinson's disease and syndrome. Carbidopa, an inhibitor of aromatic amino acid decarboxylation, is a white, crystalline compound, slightly soluble in water, with a molecular weight of 244.3. It is designated chemically as (—)-L-α­ hydrazino-α-methyl-β-(3,4-dihydroxybenzene) propanoic acid monohydrate. Its empirical formula is C10H14N2O4•H2O, and its structural formula is: structural formula Tablet content is expressed in terms of anhydrous carbidopa which has a molecular weight of 226.3. Levodopa, an aromatic amino acid, is a white, crystalline compound, slightly soluble in water, with a molecular weight of 197.2. It is designated chemically as (—)-L-α-amino-β-(3,4-dihydroxybenzene) propanoic acid. Its empirical formula is C9H11NO4, and its structural formula is: structural formula SINEMET is supplied as tablets in three strengths: SINEMET 25-100, containing 25 mg of carbidopa and 100 mg of levodopa. SINEMET 10-100, containing 10 mg of carbidopa and 100 mg of levodopa. SINEMET 25-250, containing 25 mg of carbidopa and 250 mg of levodopa. Inactive ingredients are hydroxypropyl cellulose, pregelatinized starch, crospovidone, microcrystalline cellulose, and magnesium stearate. SINEMET 10-100 and 25-250 Tablets also contain FD&C Blue #2/Indigo Carmine AL. SINEMET 25-100 Tablets also contain D&C Yellow #10 Lake. CLINICAL PHARMACOLOGY Mechanism of Action Parkinson's disease is a progressive, neurodegenerative disorder of the extrapyramidal nervous system affecting the mobility and control of the skeletal muscular system. Its characteristic features include resting tremor, rigidity, and bradykinetic movements. Symptomatic treatments, such as levodopa therapies, may permit the patient better mobility. Current evidence indicates that symptoms of Parkinson's disease are related to depletion of dopamine in the corpus striatum. Administration of dopamine is ineffective in the treatment of Parkinson's disease apparently because it does not cross the blood-brain barrier. However, levodopa, the metabolic precursor of dopamine, does cross the blood-brain barrier, and presumably is converted to dopamine in the brain. This is thought to be the mechanism whereby levodopa relieves symptoms of Parkinson's disease. 1 Reference ID: 3594908 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda Pharmacodynamics W hen levodopa is administered orally, it is rapidly decarboxylated to dopamine in extracerebral tissues so that only a small portion of a given dose is transported unchanged to the central nervous system. For this reason, large doses of levodopa are required for adequate therapeutic effect, and these may often be accompanied by nausea and other adverse reactions, some of which are attributable to dopamine formed in extracerebral tissues. Since levodopa competes with certain amino acids for transport across the gut wall, the absorption of levodopa may be impaired in some patients on a high protein diet. Carbidopa inhibits decarboxylation of peripheral levodopa. It does not cross the blood-brain barrier and does not affect the metabolism of levodopa within the central nervous system. The incidence of levodopa-induced nausea and vomiting is less with SINEMET than with levodopa. In many patients, this reduction in nausea and vomiting will permit more rapid dosage titration. Since its decarboxylase inhibiting activity is limited to extracerebral tissues, administration of carbidopa with levodopa makes more levodopa available for transport to the brain. Pharmacokinetics Carbidopa reduces the amount of levodopa required to produce a given response by about 75% and, when administered with levodopa, increases both plasma levels and the plasma half-life of levodopa, and decreases plasma and urinary dopamine and homovanillic acid. The plasma half-life of levodopa is about 50 minutes, without carbidopa. W hen carbidopa and levodopa are administered together, the half-life of levodopa is increased to about 1.5 hours. At steady state, the bioavailability of carbidopa from SINEMET tablets is approximately 99% relative to the concomitant administration of carbidopa and levodopa. In clinical pharmacologic studies, simultaneous administration of carbidopa and levodopa produced greater urinary excretion of levodopa in proportion to the excretion of dopamine than administration of the two drugs at separate times. Pyridoxine hydrochloride (vitamin B6), in oral doses of 10 mg to 25 mg, may reverse the effects of levodopa by increasing the rate of aromatic amino acid decarboxylation. Carbidopa inhibits this action of pyridoxine; therefore, SINEMET can be given to patients receiving supplemental pyridoxine (vitamin B6). Special Populations Geriatric: A study in eight young healthy subjects (21-22 yr) and eight elderly healthy subjects (69-76 yr) showed that the absolute bioavailability of levodopa was similar between young and elderly subjects following oral administration of levodopa and carbidopa. However, the systemic exposure (AUC) of levodopa was increased by 55% in elderly subjects compared to young subjects. Based on another study in forty patients with Parkinson’s disease, there was a correlation between age of patients and the increase of AUC of levodopa following administration of levodopa and an inhibitor of peripheral dopa decarboxylase. AUC of levodopa was increased by 28% in elderly patients (≥ 65 yr) compared to young patients (< 65 yr). Additionally, mean value of Cmax for levodopa was increased by 24% in elderly patients (≥ 65 yr) compared to young patients (< 65 yr) (see PRECAUTIONS, Geriatric Use). The AUC of carbidopa was increased in elderly subjects (n=10, 65-76 yr) by 29% compared to young subjects (n=24, 23-64 yr) following IV administration of 50 mg levodopa with carbidopa (50 mg). This increase is not considered a clinically significant impact. INDICATIONS AND USAGE SINEMET is indicated in the treatment of Parkinson's disease, post-encephalitic parkinsonism, and symptomatic parkinsonism that may follow carbon monoxide intoxication or manganese intoxication. Carbidopa allows patients treated for Parkinson's disease to use much lower doses of levodopa. Some patients who responded poorly to levodopa have improved on SINEMET. This is most likely due to decreased peripheral decarboxylation of levodopa caused by administration of carbidopa rather than by a primary effect of carbidopa on the nervous system. Carbidopa has not been shown to enhance the intrinsic efficacy of levodopa. 2 Reference ID: 3594908 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda Carbidopa may also reduce nausea and vomiting and permit more rapid titration of levodopa. CONTRAINDICATIONS Nonselective monoamine oxidase (MAO) inhibitors are contraindicated for use with SINEMET. These inhibitors must be discontinued at least two weeks prior to initiating therapy with SINEMET. SINEMET may be administered concomitantly with the manufacturer's recommended dose of an MAO inhibitor with selectivity for MAO type B (e.g., selegiline HCl) (see PRECAUTIONS, Drug Interactions). SINEMET is contraindicated in patients with known hypersensitivity to any component of this drug, and in patients with narrow-angle glaucoma. WARNINGS When SINEMET is to be given to patients who are being treated with levodopa, levodopa must be discontinued at least twelve hours before therapy with SINEMET is started. In order to reduce adverse reactions, it is necessary to individualize therapy. See DOSAGE AND ADMINISTRATION section before initiating therapy. The addition of carbidopa with levodopa in the form of SINEMET reduces the peripheral effects (nausea, vomiting) due to decarboxylation of levodopa; however, carbidopa does not decrease the adverse reactions due to the central effects of levodopa. Because carbidopa permits more levodopa to reach the brain and more dopamine to be formed, certain adverse central nervous system (CNS) effects, e.g., dyskinesias (involuntary movements), may occur at lower dosages and sooner with SINEMET than with levodopa alone. All patients should be observed carefully for the development of depression with concomitant suicidal tendencies. SINEMET should be administered cautiously to patients with severe cardiovascular or pulmonary disease, bronchial asthma, renal, hepatic or endocrine disease. As with levodopa, care should be exercised in administering SINEMET to patients with a history of myocardial infarction who have residual atrial, nodal, or ventricular arrhythmias. In such patients, cardiac function should be monitored with particular care during the period of initial dosage adjustment, in a facility with provisions for intensive cardiac care. As with levodopa, treatment with SINEMET may increase the possibility of upper gastrointestinal hemorrhage in patients with a history of peptic ulcer. Falling Asleep During Activities of Daily Living and Somnolence Patients taking SINEMET alone or with other dopaminergic drugs have reported suddenly falling asleep without prior warning of sleepiness while engaged in activities of daily living (includes operation of motor vehicles). Road traffic accidents attributed to sudden sleep onset have been reported. Although many patients reported somnolence while on dopaminergic medications, there have been reports of road traffic accidents attributed to sudden onset of sleep in which the patient did not perceive any warning signs, such as excessive drowsiness, and believed that they were alert immediately prior to the event. Sudden onset of sleep has been reported to occur as long as one year after the initiation of treatment. Falling asleep while engaged in activities of daily living usually occurs in patients experiencing pre­ existing somnolence, although some patients may not give such a history. For this reason, prescribers should reassess patients for drowsiness or sleepiness especially since some of the events occur well after the start of treatment. Prescribers should be aware that patients may not acknowledge drowsiness or sleepiness until directly questioned about drowsiness or sleepiness during specific activities. Patients should be advised to exercise caution while driving or operating machines during treatment with SINEMET. Patients who have already experienced somnolence or an episode of sudden sleep onset should not participate in these activities during treatment with SINEMET. Before initiating treatment with SINEMET, advise patients about the potential to develop drowsiness and ask specifically about factors that may increase the risk for somnolence with SINEMET such as the use of concomitant sedating medications and the presence of sleep disorders. Consider discontinuing SINEMET in patients who report significant daytime sleepiness or episodes of falling asleep during 3 Reference ID: 3594908 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda activities that require active participation (e.g., conversations, eating, etc.). If treatment with SINEMET continues, patients should be advised not to drive and to avoid other potentially dangerous activities that might result in harm if the patients become somnolent. There is insufficient information to establish that dose reduction will eliminate episodes of falling asleep while engaged in activities of daily living. Hyperpyrexia and Confusion Sporadic cases of a symptom complex resembling neuroleptic malignant syndrome (NMS) have been reported in association with dose reductions or withdrawal of certain antiparkinsonian agents such as levodopa, carbidopa levodopa, or carbidopa levodopa extended release. Therefore, patients should be observed carefully when the dosage of levodopa is reduced abruptly or discontinued, especially if the patient is receiving neuroleptics. NMS is an uncommon but life-threatening syndrome characterized by fever or hyperthermia. Neurological findings, including muscle rigidity, involuntary movements, altered consciousness, mental status changes; other disturbances, such as autonomic dysfunction, tachycardia, tachypnea, sweating, hyper- or hypotension; laboratory findings, such as creatine phosphokinase elevation, leukocytosis, myoglobinuria, and increased serum myoglobin have been reported. The early diagnosis of this condition is important for the appropriate management of these patients. Considering NMS as a possible diagnosis and ruling out other acute illnesses (e.g., pneumonia, systemic infection, etc.) is essential. This may be especially complex if the clinical presentation includes both serious medical illness and untreated or inadequately treated extrapyramidal signs and symptoms (EPS). Other important considerations in the differential diagnosis include central anticholinergic toxicity, heat stroke, drug fever, and primary central nervous system (CNS) pathology. The management of NMS should include: 1) intensive symptomatic treatment and medical monitoring and 2) treatment of any concomitant serious medical problems for which specific treatments are available. Dopamine agonists, such as bromocriptine, and muscle relaxants, such as dantrolene, are often used in the treatment of NMS; however, their effectiveness has not been demonstrated in controlled studies. PRECAUTIONS General As with levodopa, periodic evaluations of hepatic, hematopoietic, cardiovascular, and renal function are recommended during extended therapy. Patients with chronic wide-angle glaucoma may be treated cautiously with SINEMET provided the intraocular pressure is well-controlled and the patient is monitored carefully for changes in intraocular pressure during therapy. Dyskinesia Levodopa alone, as well as SINEMET, is associated with dyskinesias. The occurrence of dyskinesias may require dosage reduction. Hallucinations / Psychotic-Like Behavior Hallucinations and psychotic-like behavior have been reported with dopaminergic medications. In general, hallucinations present shortly after the initiation of therapy and may be responsive to dose reduction in levodopa. Hallucinations may be accompanied by confusion and to a lesser extent sleep disorder (insomnia) and excessive dreaming. SINEMET may have similar effects on thinking and behavior. This abnormal thinking and behavior may present with one or more symptoms, including paranoid ideation, delusions, hallucinations, confusion, psychotic-like behavior, disorientation, aggressive behavior, agitation, and delirium. Ordinarily, patients with a major psychotic disorder should not be treated with SINEMET, because of the risk of exacerbating psychosis. In addition, certain medications used to treat psychosis may exacerbate the symptoms of Parkinson’s disease and may decrease the effectiveness of SINEMET. Impulse Control / Compulsive Behaviors Reports of patients taking dopaminergic medications (medications that increase central dopaminergic tone), suggest that patients may experience an intense urge to gamble, increased sexual urges, intense urges to spend money, binge eating, and/or other intense urges, and the inability to control these urges. In some cases, although not all, these urges were reported to have stopped when the dose was reduced or 4 Reference ID: 3594908 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda the medication was discontinued. Because patients may not recognize these behaviors as abnormal, it is important for prescribers to specifically ask patients or the caregivers about the development of new or increased gambling urges, sexual urges, uncontrolled spending or other urges while being treated with SINEMET. Physicians should consider dose reduction or stopping the medication if a patient develops such urges while taking SINEMET [see Information for Patients]. Melanoma Epidemiological studies have shown that patients with Parkinson’s disease have a higher risk (2- to approximately 6-fold higher) of developing melanoma than the general population. W hether the increased risk observed was due to Parkinson’s disease or other factors, such as drugs used to treat Parkinson’s disease, is unclear. For the reasons stated above, patients and providers are advised to monitor for melanomas frequently and on a regular basis when using SINEMET for any indication. Ideally, periodic skin examinations should be performed by appropriately qualified individuals (e.g., dermatologists). Information for Patients The patient should be informed that SINEMET is an immediate-release formulation of carbidopa levodopa that is designed to begin release of ingredients within 30 minutes. It is important that SINEMET be taken at regular intervals according to the schedule outlined by the physician. The patient should be cautioned not to change the prescribed dosage regimen and not to add any additional antiparkinson medications, including other carbidopa levodopa preparations, without first consulting the physician. Patients should be advised that sometimes a ‘wearing-off’ effect may occur at the end of the dosing interval. The physician should be notified if such response poses a problem to lifestyle. Patients should be advised that occasionally, dark color (red, brown, or black) may appear in saliva, urine, or sweat after ingestion of SINEMET. Although the color appears to be clinically insignificant, garments may become discolored. The patient should be advised that a change in diet to foods that are high in protein may delay the absorption of levodopa and may reduce the amount taken up in the circulation. Excessive acidity also delays stomach emptying, thus delaying the absorption of levodopa. Iron salts (such as in multivitamin tablets) may also reduce the amount of levodopa available to the body. The above factors may reduce the clinical effectiveness of the levodopa or carbidopa levodopa therapy. Patients should be alerted to the possibility of sudden onset of sleep during daily activities, in some cases without awareness or warning signs, when they are taking dopaminergic agents, including levodopa. Patients should be advised to exercise caution while driving or operating machinery and that if they have experienced somnolence and/or sudden sleep onset, they must refrain from these activities. (See W ARNINGS, Falling Asleep During Activities of Daily Living and Somnolence.) There have been reports of patients experiencing intense urges to gamble, increased sexual urges, and other intense urges, and the inability to control these urges while taking one or more of the medications that increase central dopaminergic tone and that are generally used for the treatment of Parkinson’s disease, including SINEMET. Although it is not proven that the medications caused these events, these urges were reported to have stopped in some cases when the dose was reduced or the medication was stopped. Prescribers should ask patients about the development of new or increased gambling urges, sexual urges or other urges while being treated with SINEMET. Patients should inform their physician if they experience new or increased gambling urges, increased sexual urges, or other intense urges while taking SINEMET. Physicians should consider dose reduction or stopping the medication if a patient develops such urges while taking SINEMET (See PRECAUTIONS, Impulse Control / Compulsive Behaviors). Laboratory Tests Abnormalities in laboratory tests may include elevations of liver function tests such as alkaline phosphatase, SGOT (AST), SGPT (ALT), lactic dehydrogenase (LDH), and bilirubin. Abnormalities in blood urea nitrogen (BUN) and positive Coombs test have also been reported. Commonly, levels of blood urea nitrogen, creatinine, and uric acid are lower during administration of SINEMET than with levodopa. SINEMET may cause a false-positive reaction for urinary ketone bodies when a test tape is used for determination of ketonuria. This reaction will not be altered by boiling the urine specimen. False-negative tests may result with the use of glucose-oxidase methods of testing for glucosuria. 5 Reference ID: 3594908 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda Cases of falsely diagnosed pheochromocytoma in patients on carbidopa levodopa therapy have been reported very rarely. Caution should be exercised when interpreting the plasma and urine levels of catecholamines and their metabolites in patients on levodopa or carbidopa levodopa therapy. Drug Interactions Caution should be exercised when the following drugs are administered concomitantly with SINEMET. Symptomatic postural hypotension occurred when SINEMET was added to the treatment of a patient receiving antihypertensive drugs. Therefore, when therapy with SINEMET is started, dosage adjustment of the antihypertensive drug may be required. For patients receiving MAO inhibitors (Type A or B), see CONTRAINDICATIONS. Concomitant therapy with selegiline and carbidopa levodopa may be associated with severe orthostatic hypotension not attributable to carbidopa levodopa alone (see CONTRAINDICATIONS). There have been rare reports of adverse reactions, including hypertension and dyskinesia, resulting from the concomitant use of tricyclic antidepressants and SINEMET. Dopamine D2 receptor antagonists (e.g., phenothiazines, butyrophenones, risperidone) and isoniazid may reduce the therapeutic effects of levodopa. In addition, the beneficial effects of levodopa in Parkinson's disease have been reported to be reversed by phenytoin and papaverine. Patients taking these drugs with SINEMET should be carefully observed for loss of therapeutic response. Use of SINEMET with dopamine-depleting agents (e.g., reserpine and tetrabenazine) or other drugs known to deplete monoamine stores is not recommended. SINEMET and iron salts or multivitamins containing iron salts should be coadministered with caution. Iron salts can form chelates with levodopa and carbidopa and consequently reduce the bioavailability of carbidopa and levodopa. Although metoclopramide may increase the bioavailability of levodopa by increasing gastric emptying, metoclopramide may also adversely affect disease control by its dopamine receptor antagonistic properties. Carcinogenesis, Mutagenesis, Impairment of Fertility In a two-year bioassay of SINEMET, no evidence of carcinogenicity was found in rats receiving doses of approximately two times the maximum daily human dose of carbidopa and four times the maximum daily human dose of levodopa. In reproduction studies with SINEMET, no effects on fertility were found in rats receiving doses of approximately two times the maximum daily human dose of carbidopa and four times the maximum daily human dose of levodopa. Pregnancy Pregnancy Category C. No teratogenic effects were observed in a study in mice receiving up to 20 times the maximum recommended human dose of SINEMET. There was a decrease in the number of live pups delivered by rats receiving approximately two times the maximum recommended human dose of carbidopa and approximately five times the maximum recommended human dose of levodopa during organogenesis. SINEMET caused both visceral and skeletal malformations in rabbits at all doses and ratios of carbidopa/levodopa tested, which ranged from 10 times/5 times the maximum recommended human dose of carbidopa/levodopa to 20 times/10 times the maximum recommended human dose of carbidopa/levodopa. There are no adequate or well-controlled studies in pregnant women. It has been reported from individual cases that levodopa crosses the human placental barrier, enters the fetus, and is metabolized. Carbidopa concentrations in fetal tissue appeared to be minimal. Use of SINEMET in women of childbearing potential requires that the anticipated benefits of the drug be weighed against possible hazards to mother and child. Nursing Mothers Levodopa has been detected in human milk. Caution should be exercised when SINEMET is administered to a nursing woman. 6 Reference ID: 3594908 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda Pediatric Use Safety and effectiveness in pediatric patients have not been established. Use of the drug in patients below the age of 18 is not recommended. Geriatric Use In the clinical efficacy trials for SINEMET, almost half of the patients were older than 65, but few were older than 75. No overall meaningful differences in safety or effectiveness were observed between these subjects and younger subjects, but greater sensitivity of some older individuals to adverse drug reactions such as hallucinations cannot be ruled out. There is no specific dosing recommendation based upon clinical pharmacology data as SINEMET is titrated as tolerated for clinical effect. ADVERSE REACTIONS The most common adverse reactions reported with SINEMET have included dyskinesias, such as choreiform, dystonic, and other involuntary movements, and nausea. The following other adverse reactions have been reported with SINEMET: Body as a Whole Chest pain, asthenia. Cardiovascular Cardiac irregularities, hypotension, orthostatic effects including orthostatic hypotension, hypertension, syncope, phlebitis, palpitation. Gastrointestinal Dark saliva, gastrointestinal bleeding, development of duodenal ulcer, anorexia, vomiting, diarrhea, constipation, dyspepsia, dry mouth, taste alterations. Hematologic Agranulocytosis, hemolytic and non-hemolytic anemia, thrombocytopenia, leukopenia. Hypersensitivity Angioedema, urticaria, pruritus, Henoch-Schönlein purpura, bullous lesions (including pemphigus-like reactions). Musculoskeletal Back pain, shoulder pain, muscle cramps. Nervous System/Psychiatric Psychotic episodes including delusions, hallucinations, and paranoid ideation, bradykinetic episodes ("on-off" phenomenon), confusion, agitation, dizziness, somnolence, dream abnormalities including nightmares, insomnia, paresthesia, headache, depression with or without development of suicidal tendencies, dementia, pathological gambling, increased libido including hypersexuality, impulse control symptoms. Convulsions also have occurred; however, a causal relationship with SINEMET has not been established. Respiratory Dyspnea, upper respiratory infection.

Laboratory Tests Decreased white blood cell count and serum potassium; increased serum creatinine and uric acid; protein and glucose in urine. OVERDOSAGE Management of acute overdosage with SINEMET is the same as management of acute overdosage with levodopa. Pyridoxine is not effective in reversing the actions of SINEMET. General supportive measures should be employed, along with immediate gastric lavage. Intravenous fluids should be administered judiciously and an adequate airway maintained. Electrocardiographic monitoring should be instituted and the patient carefully observed for the development of arrhythmias; if required, appropriate antiarrhythmic therapy should be given. The possibility that the patient may have taken other drugs as well as SINEMET should be taken into consideration. To date, no experience has been reported with dialysis; hence, its value in overdosage is not known. Based on studies in which high doses of levodopa and/or carbidopa were administered, a significant proportion of rats and mice given single oral doses of levodopa of approximately 1500-2000 mg/kg are expected to die. A significant proportion of infant rats of both sexes are expected to die at a dose of 800 mg/kg. A significant proportion of rats are expected to die after treatment with similar doses of carbidopa. The addition of carbidopa in a 1:10 ratio with levodopa increases the dose at which a significant proportion of mice are expected to die to 3360 mg/kg. DOSAGE AND ADMINISTRATION The optimum daily dosage of SINEMET must be determined by careful titration in each patient. SINEMET tablets are available in a 1:4 ratio of carbidopa to levodopa (SINEMET 25-100) as well as 1:10 ratio (SINEMET 25-250 and SINEMET 10-100). Tablets of the two ratios may be given separately or combined as needed to provide the optimum dosage. Studies show that peripheral dopa decarboxylase is saturated by carbidopa at approximately 70 to 100 mg a day. Patients receiving less than this amount of carbidopa are more likely to experience nausea and vomiting. 8 Reference ID: 3594908 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda Usual Initial Dosage Dosage is best initiated with one tablet of SINEMET 25-100 three times a day. This dosage schedule provides 75 mg of carbidopa per day. Dosage may be increased by one tablet every day or every other day, as necessary, until a dosage of eight tablets of SINEMET 25-100 a day is reached. If SINEMET 10-100 is used, dosage may be initiated with one tablet three or four times a day. However, this will not provide an adequate amount of carbidopa for many patients. Dosage may be increased by one tablet every day or every other day until a total of eight tablets (2 tablets q.i.d.) is reached. How to Transfer Patients from Levodopa Levodopa must be discontinued at least twelve hours before starting SINEMET. A daily dosage of SINEMET should be chosen that will provide approximately 25% of the previous levodopa dosage. Patients who are taking less than 1500 mg of levodopa a day should be started on one tablet of SINEMET 25-100 three or four times a day. The suggested starting dosage for most patients taking more than 1500 mg of levodopa is one tablet of SINEMET 25-250 three or four times a day. Maintenance Therapy should be individualized and adjusted according to the desired therapeutic response. At least 70 to 100 mg of carbidopa per day should be provided. W hen a greater proportion of carbidopa is required, one tablet of SINEMET 25-100 may be substituted for each tablet of SINEMET 10-100. W hen more levodopa is required, SINEMET 25-250 should be substituted for SINEMET 25-100 or SINEMET 10­ 100. If necessary, the dosage of carbidopa levodopa 25-250 may be increased by one-half or one tablet every day or every other day to a maximum of eight tablets a day. Experience with total daily dosages of carbidopa greater than 200 mg is limited. Because both therapeutic and adverse responses occur more rapidly with SINEMET than with levodopa alone, patients should be monitored closely during the dose adjustment period. Specifically, involuntary movements will occur more rapidly with SINEMET than with levodopa. The occurrence of involuntary movements may require dosage reduction. Blepharospasm may be a useful early sign of excess dosage in some patients. Addition of Other Antiparkinsonian Medications Standard drugs for Parkinson's disease, other than levodopa without a decarboxylase inhibitor, may be used concomitantly while SINEMET is being administered, although dosage adjustments may be required. Interruption of Therapy Sporadic cases of hyperpyrexia and confusion have been associated with dose reductions and withdrawal of SINEMET. Patients should be observed carefully if abrupt reduction or discontinuation of SINEMET is required, especially if the patient is receiving neuroleptics. (See W ARNINGS.) If general anesthesia is required, SINEMET may be continued as long as the patient is permitted to take fluids and medication by mouth. If therapy is interrupted temporarily, the patient should be observed for symptoms resembling NMS, and the usual daily dosage may be administered as soon as the patient is able to take oral medication.

SINEMET ® (carbidopa levodopa) Tablets DESCRIPTION SINEMET® (carbidopa levodopa) is a combination of carbidopa and levodopa for the treatment of Parkinson's disease and syndrome. Carbidopa, an inhibitor of aromatic amino acid decarboxylation, is a white, crystalline compound, slightly soluble in water, with a molecular weight of 244.3. It is designated chemically as (—)-L-α­ hydrazino-α-methyl-β-(3,4-dihydroxybenzene) propanoic acid monohydrate. Its empirical formula is C10H14N2O4•H2O, and its structural formula is: structural formula Tablet content is expressed in terms of anhydrous carbidopa which has a molecular weight of 226.3. Levodopa, an aromatic amino acid, is a white, crystalline compound, slightly soluble in water, with a molecular weight of 197.2. It is designated chemically as (—)-L-α-amino-β-(3,4-dihydroxybenzene) propanoic acid. Its empirical formula is C9H11NO4, and its structural formula is: structural formula SINEMET is supplied as tablets in three strengths: SINEMET 25-100, containing 25 mg of carbidopa and 100 mg of levodopa. SINEMET 10-100, containing 10 mg of carbidopa and 100 mg of levodopa. SINEMET 25-250, containing 25 mg of carbidopa and 250 mg of levodopa. Inactive ingredients are hydroxypropyl cellulose, pregelatinized starch, crospovidone, microcrystalline cellulose, and magnesium stearate. SINEMET 10-100 and 25-250 Tablets also contain FD&C Blue #2/Indigo Carmine AL. SINEMET 25-100 Tablets also contain D&C Yellow #10 Lake. CLINICAL PHARMACOLOGY Mechanism of Action Parkinson's disease is a progressive, neurodegenerative disorder of the extrapyramidal nervous system affecting the mobility and control of the skeletal muscular system. Its characteristic features include resting tremor, rigidity, and bradykinetic movements. Symptomatic treatments, such as levodopa therapies, may permit the patient better mobility. Current evidence indicates that symptoms of Parkinson's disease are related to depletion of dopamine in the corpus striatum. Administration of dopamine is ineffective in the treatment of Parkinson's disease apparently because it does not cross the blood-brain barrier. However, levodopa, the metabolic precursor of dopamine, does cross the blood-brain barrier, and presumably is converted to dopamine in the brain. This is thought to be the mechanism whereby levodopa relieves symptoms of Parkinson's disease. 1 Reference ID: 3594908 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda Pharmacodynamics W hen levodopa is administered orally, it is rapidly decarboxylated to dopamine in extracerebral tissues so that only a small portion of a given dose is transported unchanged to the central nervous system. For this reason, large doses of levodopa are required for adequate therapeutic effect, and these may often be accompanied by nausea and other adverse reactions, some of which are attributable to dopamine formed in extracerebral tissues. Since levodopa competes with certain amino acids for transport across the gut wall, the absorption of levodopa may be impaired in some patients on a high protein diet. Carbidopa inhibits decarboxylation of peripheral levodopa. It does not cross the blood-brain barrier and does not affect the metabolism of levodopa within the central nervous system. The incidence of levodopa-induced nausea and vomiting is less with SINEMET than with levodopa. In many patients, this reduction in nausea and vomiting will permit more rapid dosage titration. Since its decarboxylase inhibiting activity is limited to extracerebral tissues, administration of carbidopa with levodopa makes more levodopa available for transport to the brain. Pharmacokinetics Carbidopa reduces the amount of levodopa required to produce a given response by about 75% and, when administered with levodopa, increases both plasma levels and the plasma half-life of levodopa, and decreases plasma and urinary dopamine and homovanillic acid. The plasma half-life of levodopa is about 50 minutes, without carbidopa. W hen carbidopa and levodopa are administered together, the half-life of levodopa is increased to about 1.5 hours. At steady state, the bioavailability of carbidopa from SINEMET tablets is approximately 99% relative to the concomitant administration of carbidopa and levodopa. In clinical pharmacologic studies, simultaneous administration of carbidopa and levodopa produced greater urinary excretion of levodopa in proportion to the excretion of dopamine than administration of the two drugs at separate times. Pyridoxine hydrochloride (vitamin B6), in oral doses of 10 mg to 25 mg, may reverse the effects of levodopa by increasing the rate of aromatic amino acid decarboxylation. Carbidopa inhibits this action of pyridoxine; therefore, SINEMET can be given to patients receiving supplemental pyridoxine (vitamin B6). Special Populations Geriatric: A study in eight young healthy subjects (21-22 yr) and eight elderly healthy subjects (69-76 yr) showed that the absolute bioavailability of levodopa was similar between young and elderly subjects following oral administration of levodopa and carbidopa. However, the systemic exposure (AUC) of levodopa was increased by 55% in elderly subjects compared to young subjects. Based on another study in forty patients with Parkinson’s disease, there was a correlation between age of patients and the increase of AUC of levodopa following administration of levodopa and an inhibitor of peripheral dopa decarboxylase. AUC of levodopa was increased by 28% in elderly patients (≥ 65 yr) compared to young patients (< 65 yr). Additionally, mean value of Cmax for levodopa was increased by 24% in elderly patients (≥ 65 yr) compared to young patients (< 65 yr) (see PRECAUTIONS, Geriatric Use). The AUC of carbidopa was increased in elderly subjects (n=10, 65-76 yr) by 29% compared to young subjects (n=24, 23-64 yr) following IV administration of 50 mg levodopa with carbidopa (50 mg). This increase is not considered a clinically significant impact. INDICATIONS AND USAGE SINEMET is indicated in the treatment of Parkinson's disease, post-encephalitic parkinsonism, and symptomatic parkinsonism that may follow carbon monoxide intoxication or manganese intoxication. Carbidopa allows patients treated for Parkinson's disease to use much lower doses of levodopa. Some patients who responded poorly to levodopa have improved on SINEMET. This is most likely due to decreased peripheral decarboxylation of levodopa caused by administration of carbidopa rather than by a primary effect of carbidopa on the nervous system. Carbidopa has not been shown to enhance the intrinsic efficacy of levodopa. 2 Reference ID: 3594908 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda Carbidopa may also reduce nausea and vomiting and permit more rapid titration of levodopa. CONTRAINDICATIONS Nonselective monoamine oxidase (MAO) inhibitors are contraindicated for use with SINEMET. These inhibitors must be discontinued at least two weeks prior to initiating therapy with SINEMET. SINEMET may be administered concomitantly with the manufacturer's recommended dose of an MAO inhibitor with selectivity for MAO type B (e.g., selegiline HCl) (see PRECAUTIONS, Drug Interactions). SINEMET is contraindicated in patients with known hypersensitivity to any component of this drug, and in patients with narrow-angle glaucoma. WARNINGS When SINEMET is to be given to patients who are being treated with levodopa, levodopa must be discontinued at least twelve hours before therapy with SINEMET is started. In order to reduce adverse reactions, it is necessary to individualize therapy. See DOSAGE AND ADMINISTRATION section before initiating therapy. The addition of carbidopa with levodopa in the form of SINEMET reduces the peripheral effects (nausea, vomiting) due to decarboxylation of levodopa; however, carbidopa does not decrease the adverse reactions due to the central effects of levodopa. Because carbidopa permits more levodopa to reach the brain and more dopamine to be formed, certain adverse central nervous system (CNS) effects, e.g., dyskinesias (involuntary movements), may occur at lower dosages and sooner with SINEMET than with levodopa alone. All patients should be observed carefully for the development of depression with concomitant suicidal tendencies. SINEMET should be administered cautiously to patients with severe cardiovascular or pulmonary disease, bronchial asthma, renal, hepatic or endocrine disease. As with levodopa, care should be exercised in administering SINEMET to patients with a history of myocardial infarction who have residual atrial, nodal, or ventricular arrhythmias. In such patients, cardiac function should be monitored with particular care during the period of initial dosage adjustment, in a facility with provisions for intensive cardiac care. As with levodopa, treatment with SINEMET may increase the possibility of upper gastrointestinal hemorrhage in patients with a history of peptic ulcer. Falling Asleep During Activities of Daily Living and Somnolence Patients taking SINEMET alone or with other dopaminergic drugs have reported suddenly falling asleep without prior warning of sleepiness while engaged in activities of daily living (includes operation of motor vehicles). Road traffic accidents attributed to sudden sleep onset have been reported. Although many patients reported somnolence while on dopaminergic medications, there have been reports of road traffic accidents attributed to sudden onset of sleep in which the patient did not perceive any warning signs, such as excessive drowsiness, and believed that they were alert immediately prior to the event. Sudden onset of sleep has been reported to occur as long as one year after the initiation of treatment. Falling asleep while engaged in activities of daily living usually occurs in patients experiencing pre­ existing somnolence, although some patients may not give such a history. For this reason, prescribers should reassess patients for drowsiness or sleepiness especially since some of the events occur well after the start of treatment. Prescribers should be aware that patients may not acknowledge drowsiness or sleepiness until directly questioned about drowsiness or sleepiness during specific activities. Patients should be advised to exercise caution while driving or operating machines during treatment with SINEMET. Patients who have already experienced somnolence or an episode of sudden sleep onset should not participate in these activities during treatment with SINEMET. Before initiating treatment with SINEMET, advise patients about the potential to develop drowsiness and ask specifically about factors that may increase the risk for somnolence with SINEMET such as the use of concomitant sedating medications and the presence of sleep disorders. Consider discontinuing SINEMET in patients who report significant daytime sleepiness or episodes of falling asleep during 3 Reference ID: 3594908 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda activities that require active participation (e.g., conversations, eating, etc.). If treatment with SINEMET continues, patients should be advised not to drive and to avoid other potentially dangerous activities that might result in harm if the patients become somnolent. There is insufficient information to establish that dose reduction will eliminate episodes of falling asleep while engaged in activities of daily living. Hyperpyrexia and Confusion Sporadic cases of a symptom complex resembling neuroleptic malignant syndrome (NMS) have been reported in association with dose reductions or withdrawal of certain antiparkinsonian agents such as levodopa, carbidopa levodopa, or carbidopa levodopa extended release. Therefore, patients should be observed carefully when the dosage of levodopa is reduced abruptly or discontinued, especially if the patient is receiving neuroleptics. NMS is an uncommon but life-threatening syndrome characterized by fever or hyperthermia. Neurological findings, including muscle rigidity, involuntary movements, altered consciousness, mental status changes; other disturbances, such as autonomic dysfunction, tachycardia, tachypnea, sweating, hyper- or hypotension; laboratory findings, such as creatine phosphokinase elevation, leukocytosis, myoglobinuria, and increased serum myoglobin have been reported. The early diagnosis of this condition is important for the appropriate management of these patients. Considering NMS as a possible diagnosis and ruling out other acute illnesses (e.g., pneumonia, systemic infection, etc.) is essential. This may be especially complex if the clinical presentation includes both serious medical illness and untreated or inadequately treated extrapyramidal signs and symptoms (EPS). Other important considerations in the differential diagnosis include central anticholinergic toxicity, heat stroke, drug fever, and primary central nervous system (CNS) pathology. The management of NMS should include: 1) intensive symptomatic treatment and medical monitoring and 2) treatment of any concomitant serious medical problems for which specific treatments are available. Dopamine agonists, such as bromocriptine, and muscle relaxants, such as dantrolene, are often used in the treatment of NMS; however, their effectiveness has not been demonstrated in controlled studies. PRECAUTIONS General As with levodopa, periodic evaluations of hepatic, hematopoietic, cardiovascular, and renal function are recommended during extended therapy. Patients with chronic wide-angle glaucoma may be treated cautiously with SINEMET provided the intraocular pressure is well-controlled and the patient is monitored carefully for changes in intraocular pressure during therapy. Dyskinesia Levodopa alone, as well as SINEMET, is associated with dyskinesias. The occurrence of dyskinesias may require dosage reduction. Hallucinations / Psychotic-Like Behavior Hallucinations and psychotic-like behavior have been reported with dopaminergic medications. In general, hallucinations present shortly after the initiation of therapy and may be responsive to dose reduction in levodopa. Hallucinations may be accompanied by confusion and to a lesser extent sleep disorder (insomnia) and excessive dreaming. SINEMET may have similar effects on thinking and behavior. This abnormal thinking and behavior may present with one or more symptoms, including paranoid ideation, delusions, hallucinations, confusion, psychotic-like behavior, disorientation, aggressive behavior, agitation, and delirium. Ordinarily, patients with a major psychotic disorder should not be treated with SINEMET, because of the risk of exacerbating psychosis. In addition, certain medications used to treat psychosis may exacerbate the symptoms of Parkinson’s disease and may decrease the effectiveness of SINEMET. Impulse Control / Compulsive Behaviors Reports of patients taking dopaminergic medications (medications that increase central dopaminergic tone), suggest that patients may experience an intense urge to gamble, increased sexual urges, intense urges to spend money, binge eating, and/or other intense urges, and the inability to control these urges. In some cases, although not all, these urges were reported to have stopped when the dose was reduced or 4 Reference ID: 3594908 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda the medication was discontinued. Because patients may not recognize these behaviors as abnormal, it is important for prescribers to specifically ask patients or the caregivers about the development of new or increased gambling urges, sexual urges, uncontrolled spending or other urges while being treated with SINEMET. Physicians should consider dose reduction or stopping the medication if a patient develops such urges while taking SINEMET [see Information for Patients]. Melanoma Epidemiological studies have shown that patients with Parkinson’s disease have a higher risk (2- to approximately 6-fold higher) of developing melanoma than the general population. W hether the increased risk observed was due to Parkinson’s disease or other factors, such as drugs used to treat Parkinson’s disease, is unclear. For the reasons stated above, patients and providers are advised to monitor for melanomas frequently and on a regular basis when using SINEMET for any indication. Ideally, periodic skin examinations should be performed by appropriately qualified individuals (e.g., dermatologists). Information for Patients The patient should be informed that SINEMET is an immediate-release formulation of carbidopa levodopa that is designed to begin release of ingredients within 30 minutes. It is important that SINEMET be taken at regular intervals according to the schedule outlined by the physician. The patient should be cautioned not to change the prescribed dosage regimen and not to add any additional antiparkinson medications, including other carbidopa levodopa preparations, without first consulting the physician. Patients should be advised that sometimes a ‘wearing-off’ effect may occur at the end of the dosing interval. The physician should be notified if such response poses a problem to lifestyle. Patients should be advised that occasionally, dark color (red, brown, or black) may appear in saliva, urine, or sweat after ingestion of SINEMET. Although the color appears to be clinically insignificant, garments may become discolored. The patient should be advised that a change in diet to foods that are high in protein may delay the absorption of levodopa and may reduce the amount taken up in the circulation. Excessive acidity also delays stomach emptying, thus delaying the absorption of levodopa. Iron salts (such as in multivitamin tablets) may also reduce the amount of levodopa available to the body. The above factors may reduce the clinical effectiveness of the levodopa or carbidopa levodopa therapy. Patients should be alerted to the possibility of sudden onset of sleep during daily activities, in some cases without awareness or warning signs, when they are taking dopaminergic agents, including levodopa. Patients should be advised to exercise caution while driving or operating machinery and that if they have experienced somnolence and/or sudden sleep onset, they must refrain from these activities. (See W ARNINGS, Falling Asleep During Activities of Daily Living and Somnolence.) There have been reports of patients experiencing intense urges to gamble, increased sexual urges, and other intense urges, and the inability to control these urges while taking one or more of the medications that increase central dopaminergic tone and that are generally used for the treatment of Parkinson’s disease, including SINEMET. Although it is not proven that the medications caused these events, these urges were reported to have stopped in some cases when the dose was reduced or the medication was stopped. Prescribers should ask patients about the development of new or increased gambling urges, sexual urges or other urges while being treated with SINEMET. Patients should inform their physician if they experience new or increased gambling urges, increased sexual urges, or other intense urges while taking SINEMET. Physicians should consider dose reduction or stopping the medication if a patient develops such urges while taking SINEMET (See PRECAUTIONS, Impulse Control / Compulsive Behaviors). Laboratory Tests Abnormalities in laboratory tests may include elevations of liver function tests such as alkaline phosphatase, SGOT (AST), SGPT (ALT), lactic dehydrogenase (LDH), and bilirubin. Abnormalities in blood urea nitrogen (BUN) and positive Coombs test have also been reported. Commonly, levels of blood urea nitrogen, creatinine, and uric acid are lower during administration of SINEMET than with levodopa. SINEMET may cause a false-positive reaction for urinary ketone bodies when a test tape is used for determination of ketonuria. This reaction will not be altered by boiling the urine specimen. False-negative tests may result with the use of glucose-oxidase methods of testing for glucosuria. 5 Reference ID: 3594908 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda Cases of falsely diagnosed pheochromocytoma in patients on carbidopa levodopa therapy have been reported very rarely. Caution should be exercised when interpreting the plasma and urine levels of catecholamines and their metabolites in patients on levodopa or carbidopa levodopa therapy. Drug Interactions Caution should be exercised when the following drugs are administered concomitantly with SINEMET. Symptomatic postural hypotension occurred when SINEMET was added to the treatment of a patient receiving antihypertensive drugs. Therefore, when therapy with SINEMET is started, dosage adjustment of the antihypertensive drug may be required. For patients receiving MAO inhibitors (Type A or B), see CONTRAINDICATIONS. Concomitant therapy with selegiline and carbidopa levodopa may be associated with severe orthostatic hypotension not attributable to carbidopa levodopa alone (see CONTRAINDICATIONS). There have been rare reports of adverse reactions, including hypertension and dyskinesia, resulting from the concomitant use of tricyclic antidepressants and SINEMET. Dopamine D2 receptor antagonists (e.g., phenothiazines, butyrophenones, risperidone) and isoniazid may reduce the therapeutic effects of levodopa. In addition, the beneficial effects of levodopa in Parkinson's disease have been reported to be reversed by phenytoin and papaverine. Patients taking these drugs with SINEMET should be carefully observed for loss of therapeutic response. Use of SINEMET with dopamine-depleting agents (e.g., reserpine and tetrabenazine) or other drugs known to deplete monoamine stores is not recommended. SINEMET and iron salts or multivitamins containing iron salts should be coadministered with caution. Iron salts can form chelates with levodopa and carbidopa and consequently reduce the bioavailability of carbidopa and levodopa. Although metoclopramide may increase the bioavailability of levodopa by increasing gastric emptying, metoclopramide may also adversely affect disease control by its dopamine receptor antagonistic properties. Carcinogenesis, Mutagenesis, Impairment of Fertility In a two-year bioassay of SINEMET, no evidence of carcinogenicity was found in rats receiving doses of approximately two times the maximum daily human dose of carbidopa and four times the maximum daily human dose of levodopa. In reproduction studies with SINEMET, no effects on fertility were found in rats receiving doses of approximately two times the maximum daily human dose of carbidopa and four times the maximum daily human dose of levodopa. Pregnancy Pregnancy Category C. No teratogenic effects were observed in a study in mice receiving up to 20 times the maximum recommended human dose of SINEMET. There was a decrease in the number of live pups delivered by rats receiving approximately two times the maximum recommended human dose of carbidopa and approximately five times the maximum recommended human dose of levodopa during organogenesis. SINEMET caused both visceral and skeletal malformations in rabbits at all doses and ratios of carbidopa/levodopa tested, which ranged from 10 times/5 times the maximum recommended human dose of carbidopa/levodopa to 20 times/10 times the maximum recommended human dose of carbidopa/levodopa. There are no adequate or well-controlled studies in pregnant women. It has been reported from individual cases that levodopa crosses the human placental barrier, enters the fetus, and is metabolized. Carbidopa concentrations in fetal tissue appeared to be minimal. Use of SINEMET in women of childbearing potential requires that the anticipated benefits of the drug be weighed against possible hazards to mother and child. Nursing Mothers Levodopa has been detected in human milk. Caution should be exercised when SINEMET is administered to a nursing woman. 6 Reference ID: 3594908 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda Pediatric Use Safety and effectiveness in pediatric patients have not been established. Use of the drug in patients below the age of 18 is not recommended. Geriatric Use In the clinical efficacy trials for SINEMET, almost half of the patients were older than 65, but few were older than 75. No overall meaningful differences in safety or effectiveness were observed between these subjects and younger subjects, but greater sensitivity of some older individuals to adverse drug reactions such as hallucinations cannot be ruled out. There is no specific dosing recommendation based upon clinical pharmacology data as SINEMET is titrated as tolerated for clinical effect. ADVERSE REACTIONS The most common adverse reactions reported with SINEMET have included dyskinesias, such as choreiform, dystonic, and other involuntary movements, and nausea. The following other adverse reactions have been reported with SINEMET: Body as a Whole Chest pain, asthenia. Cardiovascular Cardiac irregularities, hypotension, orthostatic effects including orthostatic hypotension, hypertension, syncope, phlebitis, palpitation. Gastrointestinal Dark saliva, gastrointestinal bleeding, development of duodenal ulcer, anorexia, vomiting, diarrhea, constipation, dyspepsia, dry mouth, taste alterations. Hematologic Agranulocytosis, hemolytic and non-hemolytic anemia, thrombocytopenia, leukopenia. Hypersensitivity Angioedema, urticaria, pruritus, Henoch-Schönlein purpura, bullous lesions (including pemphigus-like reactions). Musculoskeletal Back pain, shoulder pain, muscle cramps. Nervous System/Psychiatric Psychotic episodes including delusions, hallucinations, and paranoid ideation, bradykinetic episodes ("on-off" phenomenon), confusion, agitation, dizziness, somnolence, dream abnormalities including nightmares, insomnia, paresthesia, headache, depression with or without development of suicidal tendencies, dementia, pathological gambling, increased libido including hypersexuality, impulse control symptoms. Convulsions also have occurred; however, a causal relationship with SINEMET has not been established. Respiratory Dyspnea, upper respiratory infection.

Gastrointestinal Gastrointestinal pain, dysphagia, sialorrhea, flatulence, bruxism, burning sensation of the tongue, heartburn, hiccups. Metabolic Edema, weight gain, weight loss. Musculoskeletal Leg pain. Nervous System/Psychiatric Ataxia, extrapyramidal disorder, falling, anxiety, gait abnormalities, nervousness, decreased mental acuity, memory impairment, disorientation, euphoria, blepharospasm (which may be taken as an early sign of excess dosage; consideration of dosage reduction may be made at this time), trismus, increased tremor, numbness, muscle twitching, activation of latent Horner's syndrome, peripheral neuropathy. Respiratory Pharyngeal pain, cough. Skin Malignant melanoma (see also CONTRAINDICATIONS), flushing. Special Senses Oculogyric crises, diplopia, blurred vision, dilated pupils. Urogenital Urinary retention, urinary incontinence, priapism. Miscellaneous Bizarre breathing patterns, faintness, hoarseness, malaise, hot flashes, sense of stimulation. Laboratory Tests Decreased white blood cell count and serum potassium; increased serum creatinine and uric acid; protein and glucose in urine. OVERDOSAGE Management of acute overdosage with SINEMET is the same as management of acute overdosage with levodopa. Pyridoxine is not effective in reversing the actions of SINEMET. General supportive measures should be employed, along with immediate gastric lavage. Intravenous fluids should be administered judiciously and an adequate airway maintained. Electrocardiographic monitoring should be instituted and the patient carefully observed for the development of arrhythmias; if required, appropriate antiarrhythmic therapy should be given. The possibility that the patient may have taken other drugs as well as SINEMET should be taken into consideration. To date, no experience has been reported with dialysis; hence, its value in overdosage is not known. Based on studies in which high doses of levodopa and/or carbidopa were administered, a significant proportion of rats and mice given single oral doses of levodopa of approximately 1500-2000 mg/kg are expected to die. A significant proportion of infant rats of both sexes are expected to die at a dose of 800 mg/kg. A significant proportion of rats are expected to die after treatment with similar doses of carbidopa. The addition of carbidopa in a 1:10 ratio with levodopa increases the dose at which a significant proportion of mice are expected to die to 3360 mg/kg. DOSAGE AND ADMINISTRATION The optimum daily dosage of SINEMET must be determined by careful titration in each patient. SINEMET tablets are available in a 1:4 ratio of carbidopa to levodopa (SINEMET 25-100) as well as 1:10 ratio (SINEMET 25-250 and SINEMET 10-100). Tablets of the two ratios may be given separately or combined as needed to provide the optimum dosage. Studies show that peripheral dopa decarboxylase is saturated by carbidopa at approximately 70 to 100 mg a day. Patients receiving less than this amount of carbidopa are more likely to experience nausea and vomiting. 8 Reference ID: 3594908 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda Usual Initial Dosage Dosage is best initiated with one tablet of SINEMET 25-100 three times a day. This dosage schedule provides 75 mg of carbidopa per day. Dosage may be increased by one tablet every day or every other day, as necessary, until a dosage of eight tablets of SINEMET 25-100 a day is reached. If SINEMET 10-100 is used, dosage may be initiated with one tablet three or four times a day. However, this will not provide an adequate amount of carbidopa for many patients. Dosage may be increased by one tablet every day or every other day until a total of eight tablets (2 tablets q.i.d.) is reached. How to Transfer Patients from Levodopa Levodopa must be discontinued at least twelve hours before starting SINEMET. A daily dosage of SINEMET should be chosen that will provide approximately 25% of the previous levodopa dosage. Patients who are taking less than 1500 mg of levodopa a day should be started on one tablet of SINEMET 25-100 three or four times a day. The suggested starting dosage for most patients taking more than 1500 mg of levodopa is one tablet of SINEMET 25-250 three or four times a day. Maintenance Therapy should be individualized and adjusted according to the desired therapeutic response. At least 70 to 100 mg of carbidopa per day should be provided. W hen a greater proportion of carbidopa is required, one tablet of SINEMET 25-100 may be substituted for each tablet of SINEMET 10-100. W hen more levodopa is required, SINEMET 25-250 should be substituted for SINEMET 25-100 or SINEMET 10­ 100. If necessary, the dosage of carbidopa levodopa 25-250 may be increased by one-half or one tablet every day or every other day to a maximum of eight tablets a day. Experience with total daily dosages of carbidopa greater than 200 mg is limited. Because both therapeutic and adverse responses occur more rapidly with SINEMET than with levodopa alone, patients should be monitored closely during the dose adjustment period. Specifically, involuntary movements will occur more rapidly with SINEMET than with levodopa. The occurrence of involuntary movements may require dosage reduction. Blepharospasm may be a useful early sign of excess dosage in some patients. Addition of Other Antiparkinsonian Medications Standard drugs for Parkinson's disease, other than levodopa without a decarboxylase inhibitor, may be used concomitantly while SINEMET is being administered, although dosage adjustments may be required. Interruption of Therapy Sporadic cases of hyperpyrexia and confusion have been associated with dose reductions and withdrawal of SINEMET. Patients should be observed carefully if abrupt reduction or discontinuation of SINEMET is required, especially if the patient is receiving neuroleptics. (See W ARNINGS.) If general anesthesia is required, SINEMET may be continued as long as the patient is permitted to take fluids and medication by mouth. If therapy is interrupted temporarily, the patient should be observed for symptoms resembling NMS, and the usual daily dosage may be administered as soon as the patient is able to take oral medication.

s tru ctur al formul a s tru ctu ral formula FDA Approved Labeling Text for NDA 017555 Dated 1/31/11 company logo SINEMET® (carbidopa-levodopa) Tablets DESCRIPTION SINEMET® (carbidopa-levodopa) is a combination of carbidopa and levodopa for the treatment of Parkinson's disease and syndrome. Carbidopa, an inhibitor of aromatic amino acid decarboxylation, is a white, crystalline compound, slightly soluble in water, with a molecular weight of 244.3. It is designated chemically as (—)-L-α­ hydrazino-α-methyl-β-(3,4-dihydroxybenzene) propanoic acid monohydrate. Its empirical formula is C10H14N2O4•H2O, and its structural formula is: Tablet content is expressed in terms of anhydrous carbidopa which has a molecular weight of 226.3. Levodopa, an aromatic amino acid, is a white, crystalline compound, slightly soluble in water, with a molecular weight of 197.2. It is designated chemically as (—)-L-α-amino-β-(3,4-dihydroxybenzene) propanoic acid. Its empirical formula is C9H11NO4, and its structural formula is: SINEMET is supplied as tablets in three strengths: SINEMET 25-100, containing 25 mg of carbidopa and 100 mg of levodopa. SINEMET 10-100, containing 10 mg of carbidopa and 100 mg of levodopa. SINEMET 25-250, containing 25 mg of carbidopa and 250 mg of levodopa. Inactive ingredients are hydroxypropyl cellulose, pregelatinized starch, crospovidone, microcrystalline cellulose, and magnesium stearate. SINEMET 10-100 and 25-250 Tablets also contain FD&C Blue #2/Indigo Carmine AL. SINEMET 25-100 Tablets also contain D&C Yellow #10 Lake. CLINICAL PHARMACOLOGY Mechanism of Action Parkinson's disease is a progressive, neurodegenerative disorder of the extrapyramidal nervous system affecting the mobility and control of the skeletal muscular system. Its characteristic features include resting tremor, rigidity, and bradykinetic movements. Symptomatic treatments, such as levodopa therapies, may permit the patient better mobility. Current evidence indicates that symptoms of Parkinson's disease are related to depletion of dopamine in the corpus striatum. Administration of dopamine is ineffective in the treatment of Parkinson's disease Reference ID: 2898568 1 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda SINEMET® (carbidopa-levodopa) apparently because it does not cross the blood-brain barrier. However, levodopa, the metabolic precursor of dopamine, does cross the blood-brain barrier, and presumably is converted to dopamine in the brain. This is thought to be the mechanism whereby levodopa relieves symptoms of Parkinson's disease. Pharmacodynamics When levodopa is administered orally, it is rapidly decarboxylated to dopamine in extracerebral tissues so that only a small portion of a given dose is transported unchanged to the central nervous system. For this reason, large doses of levodopa are required for adequate therapeutic effect, and these may often be accompanied by nausea and other adverse reactions, some of which are attributable to dopamine formed in extracerebral tissues. Since levodopa competes with certain amino acids for transport across the gut wall, the absorption of levodopa may be impaired in some patients on a high protein diet. Carbidopa inhibits decarboxylation of peripheral levodopa. It does not cross the blood-brain barrier and does not affect the metabolism of levodopa within the central nervous system. The incidence of levodopa-induced nausea and vomiting is less with SINEMET than with levodopa. In many patients, this reduction in nausea and vomiting will permit more rapid dosage titration. Since its decarboxylase inhibiting activity is limited to extracerebral tissues, administration of carbidopa with levodopa makes more levodopa available for transport to the brain. Pharmacokinetics Carbidopa reduces the amount of levodopa required to produce a given response by about 75% and, when administered with levodopa, increases both plasma levels and the plasma half-life of levodopa, and decreases plasma and urinary dopamine and homovanillic acid. The plasma half-life of levodopa is about 50 minutes, without carbidopa. When carbidopa and levodopa are administered together, the half-life of levodopa is increased to about 1.5 hours. At steady state, the bioavailability of carbidopa from SINEMET tablets is approximately 99% relative to the concomitant administration of carbidopa and levodopa. In clinical pharmacologic studies, simultaneous administration of carbidopa and levodopa produced greater urinary excretion of levodopa in proportion to the excretion of dopamine than administration of the two drugs at separate times. Pyridoxine hydrochloride (vitamin B6), in oral doses of 10 mg to 25 mg, may reverse the effects of levodopa by increasing the rate of aromatic amino acid decarboxylation. Carbidopa inhibits this action of pyridoxine; therefore, SINEMET can be given to patients receiving supplemental pyridoxine (vitamin B6). INDICATIONS AND USAGE SINEMET is indicated in the treatment of the symptoms of idiopathic Parkinson's disease (paralysis agitans), post-encephalitic parkinsonism, and symptomatic parkinsonism which may follow injury to the nervous system by carbon monoxide intoxication and/or manganese intoxication. SINEMET is indicated in these conditions to permit the administration of lower doses of levodopa with reduced nausea and vomiting, with more rapid dosage titration, with a somewhat smoother response, and with supplemental pyridoxine (vitamin B6). In some patients a somewhat smoother antiparkinsonian effect results from therapy with SINEMET than with levodopa. However, patients with markedly irregular ("on-off") responses to levodopa have not been shown to benefit from SINEMET. Although the administration of carbidopa permits control of parkinsonism and Parkinson's disease with much lower doses of levodopa, there is no conclusive evidence at present that this is beneficial other than in reducing nausea and vomiting, permitting more rapid titration, and providing a somewhat smoother response to levodopa. Certain patients who responded poorly to levodopa have improved when SINEMET was substituted. This is most likely due to decreased peripheral decarboxylation of levodopa which results from administration of carbidopa rather than to a primary effect of carbidopa on the nervous system. Carbidopa has not been shown to enhance the intrinsic efficacy of levodopa in parkinsonian syndromes. In considering whether to give SINEMET to patients already on levodopa who have nausea and/or vomiting, the practitioner should be aware that, while many patients may be expected to improve, some do not. Since one cannot predict which patients are likely to improve, this can only be determined by a trial of therapy. It should be further noted that in controlled trials comparing SINEMET with levodopa, Reference ID: 2898568 2 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda SINEMET® (carbidopa-levodopa) about half of the patients with nausea and/or vomiting on levodopa improved spontaneously despite being retained on the same dose of levodopa during the controlled portion of the trial. CONTRAINDICATIONS Nonselective monoamine oxidase (MAO) inhibitors are contraindicated for use with SINEMET. These inhibitors must be discontinued at least two weeks prior to initiating therapy with SINEMET. SINEMET may be administered concomitantly with the manufacturer's recommended dose of an MAO inhibitor with selectivity for MAO type B (e.g., selegiline HCl) (see PRECAUTIONS, Drug Interactions). SINEMET is contraindicated in patients with known hypersensitivity to any component of this drug, and in patients with narrow-angle glaucoma. Because levodopa may activate a malignant melanoma, SINEMET should not be used in patients with suspicious, undiagnosed skin lesions or a history of melanoma. WARNINGS When SINEMET is to be given to patients who are being treated with levodopa, levodopa must be discontinued at least twelve hours before therapy with SINEMET is started. In order to reduce adverse reactions, it is necessary to individualize therapy. See DOSAGE AND ADMINISTRATION section before initiating therapy. The addition of carbidopa with levodopa in the form of SINEMET reduces the peripheral effects (nausea, vomiting) due to decarboxylation of levodopa; however, carbidopa does not decrease the adverse reactions due to the central effects of levodopa. Because carbidopa permits more levodopa to reach the brain and more dopamine to be formed, certain adverse CNS effects, e.g., dyskinesias (involuntary movements), may occur at lower dosages and sooner with SINEMET than with levodopa alone. Levodopa alone, as well as SINEMET, is associated with dyskinesias. The occurrence of dyskinesias may require dosage reduction. As with levodopa, SINEMET may cause mental disturbances. These reactions are thought to be due to increased brain dopamine following administration of levodopa. All patients should be observed carefully for the development of depression with concomitant suicidal tendencies. Patients with past or current psychoses should be treated with caution. SINEMET should be administered cautiously to patients with severe cardiovascular or pulmonary disease, bronchial asthma, renal, hepatic or endocrine disease. As with levodopa, care should be exercised in administering SINEMET to patients with a history of myocardial infarction who have residual atrial, nodal, or ventricular arrhythmias. In such patients, cardiac function should be monitored with particular care during the period of initial dosage adjustment, in a facility with provisions for intensive cardiac care. As with levodopa, treatment with SINEMET may increase the possibility of upper gastrointestinal hemorrhage in patients with a history of peptic ulcer. Neuroleptic Malignant Syndrome (NMS) Sporadic cases of a symptom complex resembling NMS have been reported in association with dose reductions or withdrawal of therapy with SINEMET. Therefore, patients should be observed carefully when the dosage of SINEMET is reduced abruptly or discontinued, especially if the patient is receiving neuroleptics. NMS is an uncommon but life-threatening syndrome characterized by fever or hyperthermia. Neurological findings, including muscle rigidity, involuntary movements, altered consciousness, mental status changes; other disturbances, such as autonomic dysfunction, tachycardia, tachypnea, sweating, hyper- or hypotension; laboratory findings, such as creatine phosphokinase elevation, leukocytosis, myoglobinuria, and increased serum myoglobin have been reported. The early diagnosis of this condition is important for the appropriate management of these patients. Considering NMS as a possible diagnosis and ruling out other acute illnesses (e.g., pneumonia, systemic infection, etc.) is essential. This may be especially complex if the clinical presentation includes both serious medical illness and untreated or inadequately treated extrapyramidal signs and symptoms (EPS). Other important considerations in the differential diagnosis include central anticholinergic toxicity, heat stroke, drug fever, and primary central nervous system (CNS) pathology. Reference ID: 2898568 3 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda SINEMET® (carbidopa-levodopa) The management of NMS should include: 1) intensive symptomatic treatment and medical monitoring and 2) treatment of any concomitant serious medical problems for which specific treatments are available. Dopamine agonists, such as bromocriptine, and muscle relaxants, such as dantrolene, are often used in the treatment of NMS, however, their effectiveness has not been demonstrated in controlled studies. PRECAUTIONS General As with levodopa, periodic evaluations of hepatic, hematopoietic, cardiovascular, and renal function are recommended during extended therapy. Patients with chronic wide-angle glaucoma may be treated cautiously with SINEMET provided the intraocular pressure is well-controlled and the patient is monitored carefully for changes in intraocular pressure during therapy. Dopaminergic agents, including levodopa, may be associated with somnolence and very rarely episodes of sudden onset of sleep. In some cases, these episodes may occur without awareness or warning during daily activities. Patients must be informed of this and advised to exercise caution while driving or operating machines while being treated with dopaminergic agents, including levodopa. Patients who have experienced somnolence and/or an episode of sudden sleep onset must refrain from driving or operating machines (see Information for Patients). Melanoma Epidemiological studies have shown that patients with Parkinson’s disease have a higher risk (2- to approximately 6-fold higher) of developing melanoma than the general population. Whether the increased risk observed was due to Parkinson’s disease or other factors, such as drugs used to treat Parkinson’s disease, is unclear. For the reasons stated above, patients and providers are advised to monitor for melanomas frequently and on a regular basis when using SINEMET for any indication. Ideally, periodic skin examinations should be performed by appropriately qualified individuals (e.g., dermatologists). Information for Patients The patient should be informed that SINEMET is an immediate-release formulation of carbidopa­ levodopa that is designed to begin release of ingredients within 30 minutes. It is important that SINEMET be taken at regular intervals according to the schedule outlined by the physician. The patient should be cautioned not to change the prescribed dosage regimen and not to add any additional antiparkinson medications, including other carbidopa-levodopa preparations, without first consulting the physician. Patients should be advised that sometimes a ‘wearing-off’ effect may occur at the end of the dosing interval. The physician should be notified if such response poses a problem to lifestyle. Patients should be advised that occasionally, dark color (red, brown, or black) may appear in saliva, urine, or sweat after ingestion of SINEMET. Although the color appears to be clinically insignificant, garments may become discolored. The patient should be advised that a change in diet to foods that are high in protein may delay the absorption of levodopa and may reduce the amount taken up in the circulation. Excessive acidity also delays stomach emptying, thus delaying the absorption of levodopa. Iron salts (such as in multivitamin tablets) may also reduce the amount of levodopa available to the body. The above factors may reduce the clinical effectiveness of the levodopa or carbidopa-levodopa therapy. Patients should be alerted to the possibility of sudden onset of sleep during daily activities, in some cases without awareness or warning signs, when they are taking dopaminergic agents, including levodopa. Patients should be advised to exercise caution while driving or operating machinery and that if they have experienced somnolence and/or sudden sleep onset, they must refrain from these activities. (See PRECAUTIONS, General.) There have been reports of patients experiencing intense urges to gamble, increased sexual urges, and other intense urges, and the inability to control these urges while taking one or more of the medications that increase central dopaminergic tone and that are generally used for the treatment of Parkinson’s disease, including SINEMET. Although it is not proven that the medications caused these events, these urges were reported to have stopped in some cases when the dose was reduced or the medication was stopped. Prescribers should ask patients about the development of new or increased Reference ID: 2898568 4 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda SINEMET® (carbidopa-levodopa) gambling urges, sexual urges or other urges while being treated with SINEMET. Patients should inform their physician if they experience new or increased gambling urges, increased sexual urges, or other intense urges while taking SINEMET. Physicians should consider dose reduction or stopping the medication if a patient develops such urges while taking SINEMET. NOTE: The suggested advice to patients being treated with SINEMET is intended to aid in the safe and effective use of this medication. It is not a disclosure of all possible adverse or intended effects. Laboratory Tests Abnormalities in laboratory tests may include elevations of liver function tests such as alkaline phosphatase, SGOT (AST), SGPT (ALT), lactic dehydrogenase, and bilirubin. Abnormalities in blood urea nitrogen and positive Coombs test have also been reported. Commonly, levels of blood urea nitrogen, creatinine, and uric acid are lower during administration of SINEMET than with levodopa. SINEMET may cause a false-positive reaction for urinary ketone bodies when a test tape is used for determination of ketonuria. This reaction will not be altered by boiling the urine specimen. False-negative tests may result with the use of glucose-oxidase methods of testing for glucosuria. Cases of falsely diagnosed pheochromocytoma in patients on carbidopa-levodopa therapy have been reported very rarely. Caution should be exercised when interpreting the plasma and urine levels of catecholamines and their metabolites in patients on levodopa or carbidopa-levodopa therapy. Drug Interactions Caution should be exercised when the following drugs are administered concomitantly with SINEMET. Symptomatic postural hypotension occurred when SINEMET was added to the treatment of a patient receiving antihypertensive drugs. Therefore, when therapy with SINEMET is started, dosage adjustment of the antihypertensive drug may be required. For patients receiving MAO inhibitors (Type A or B), see CONTRAINDICATIONS. Concomitant therapy with selegiline and carbidopa-levodopa may be associated with severe orthostatic hypotension not attributable to carbidopa-levodopa alone (see CONTRAINDICATIONS). There have been rare reports of adverse reactions, including hypertension and dyskinesia, resulting from the concomitant use of tricyclic antidepressants and SINEMET. Dopamine D2 receptor antagonists (e.g., phenothiazines, butyrophenones, risperidone) and isoniazid may reduce the therapeutic effects of levodopa. In addition, the beneficial effects of levodopa in Parkinson's disease have been reported to be reversed by phenytoin and papaverine. Patients taking these drugs with SINEMET should be carefully observed for loss of therapeutic response. Iron salts may reduce the bioavailability of levodopa and carbidopa. The clinical relevance is unclear. Although metoclopramide may increase the bioavailability of levodopa by increasing gastric emptying, metoclopramide may also adversely affect disease control by its dopamine receptor antagonistic properties. Carcinogenesis, Mutagenesis, Impairment of Fertility In a two-year bioassay of SINEMET, no evidence of carcinogenicity was found in rats receiving doses of approximately two times the maximum daily human dose of carbidopa and four times the maximum daily human dose of levodopa. In reproduction studies with SINEMET, no effects on fertility were found in rats receiving doses of approximately two times the maximum daily human dose of carbidopa and four times the maximum daily human dose of levodopa. Pregnancy Pregnancy Category C. No teratogenic effects were observed in a study in mice receiving up to 20 times the maximum recommended human dose of SINEMET. There was a decrease in the number of live pups delivered by rats receiving approximately two times the maximum recommended human dose of carbidopa and approximately five times the maximum recommended human dose of levodopa during organogenesis. SINEMET caused both visceral and skeletal malformations in rabbits at all doses and ratios of carbidopa/levodopa tested, which ranged from 10 times/5 times the maximum recommended human dose of carbidopa/levodopa to 20 times/10 times the maximum recommended human dose of carbidopa/levodopa. There are no adequate or well-controlled studies in pregnant women. It has been reported from individual cases that levodopa crosses the human placental barrier, enters the fetus, and is metabolized. Carbidopa concentrations in fetal tissue appeared to be minimal. Use of SINEMET in women of childbearing potential requires that the anticipated benefits of the drug be weighed against possible hazards to mother and child. Reference ID: 2898568 5 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda SINEMET® (carbidopa-levodopa) Nursing Mothers In a study of one nursing mother with Parkinson’s disease, excretion of levodopa in human breast milk was reported. Therefore, caution should be exercised when SINEMET is administered to a nursing woman. Pediatric Use Safety and effectiveness in pediatric patients have not been established. Use of the drug in patients below the age of 18 is not recommended. ADVERSE REACTIONS The most common adverse reactions reported with SINEMET have included dyskinesias, such as choreiform, dystonic, and other involuntary movements, and nausea. The following other adverse reactions have been reported with SINEMET: Body as a Whole Chest pain, asthenia. Cardiovascular Cardiac irregularities, hypotension, orthostatic effects including orthostatic hypotension, hypertension, syncope, phlebitis, palpitation. Gastrointestinal Dark saliva, gastrointestinal bleeding, development of duodenal ulcer, anorexia, vomiting, diarrhea, constipation, dyspepsia, dry mouth, taste alterations. Hematologic Agranulocytosis, hemolytic and non-hemolytic anemia, thrombocytopenia, leukopenia. Hypersensitivity Angioedema, urticaria, pruritus, Henoch-Schonlein purpura, bullous lesions (including pemphigus-like reactions). Musculoskeletal Back pain, shoulder pain, muscle cramps.

Laboratory Tests Decreased white blood cell count and serum potassium; increased serum creatinine and uric acid; protein and glucose in urine. OVERDOSAGE Management of acute overdosage with SINEMET is the same as management of acute overdosage with levodopa. Pyridoxine is not effective in reversing the actions of SINEMET. General supportive measures should be employed, along with immediate gastric lavage. Intravenous fluids should be administered judiciously and an adequate airway maintained. Electrocardiographic monitoring should be instituted and the patient carefully observed for the development of arrhythmias; if required, appropriate antiarrhythmic therapy should be given. The possibility that the patient may have taken other drugs as well as SINEMET should be taken into consideration. To date, no experience has been reported with dialysis; hence, its value in overdosage is not known. Based on studies in which high doses of levodopa and/or carbidopa were administered, a significant proportion of rats and mice given single oral doses of levodopa of approximately 1500-2000 mg/kg are expected to die. A significant proportion of infant rats of both sexes are expected to die at a dose of 800 mg/kg. A significant proportion of rats are expected to die after treatment with similar doses of carbidopa. The addition of carbidopa in a 1:10 ratio with levodopa increases the dose at which a significant proportion of mice are expected to die to 3360 mg/kg. DOSAGE AND ADMINISTRATION The optimum daily dosage of SINEMET must be determined by careful titration in each patient. SINEMET tablets are available in a 1:4 ratio of carbidopa to levodopa (SINEMET 25-100) as well as 1:10 ratio (SINEMET 25-250 and SINEMET 10-100). Tablets of the two ratios may be given separately or combined as needed to provide the optimum dosage. Studies show that peripheral dopa decarboxylase is saturated by carbidopa at approximately 70 to 100 mg a day. Patients receiving less than this amount of carbidopa are more likely to experience nausea and vomiting. Usual Initial Dosage Dosage is best initiated with one tablet of SINEMET 25-100 three times a day. This dosage schedule provides 75 mg of carbidopa per day. Dosage may be increased by one tablet every day or every other day, as necessary, until a dosage of eight tablets of SINEMET 25-100 a day is reached. Reference ID: 2898568 7 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda SINEMET® (carbidopa-levodopa) If SINEMET 10-100 is used, dosage may be initiated with one tablet three or four times a day. However, this will not provide an adequate amount of carbidopa for many patients. Dosage may be increased by one tablet every day or every other day until a total of eight tablets (2 tablets q.i.d.) is reached. How to Transfer Patients from Levodopa Levodopa must be discontinued at least twelve hours before starting SINEMET. A daily dosage of SINEMET should be chosen that will provide approximately 25% of the previous levodopa dosage. Patients who are taking less than 1500 mg of levodopa a day should be started on one tablet of SINEMET 25-100 three or four times a day. The suggested starting dosage for most patients taking more than 1500 mg of levodopa is one tablet of SINEMET 25-250 three or four times a day. Maintenance Therapy should be individualized and adjusted according to the desired therapeutic response. At least 70 to 100 mg of carbidopa per day should be provided. When a greater proportion of carbidopa is required, one tablet of SINEMET 25-100 may be substituted for each tablet of SINEMET 10-100. When more levodopa is required, SINEMET 25-250 should be substituted for SINEMET 25-100 or SINEMET 10-100. If necessary, the dosage of carbidopa/levodopa 25-250 may be increased by one-half or one tablet every day or every other day to a maximum of eight tablets a day. Experience with total daily dosages of carbidopa greater than 200 mg is limited. Because both therapeutic and adverse responses occur more rapidly with SINEMET than with levodopa alone, patients should be monitored closely during the dose adjustment period. Specifically, involuntary movements will occur more rapidly with SINEMET than with levodopa. The occurrence of involuntary movements may require dosage reduction. Blepharospasm may be a useful early sign of excess dosage in some patients. Addition of Other Antiparkinsonian Medications Standard drugs for Parkinson's disease, other than levodopa without a decarboxylase inhibitor, may be used concomitantly while SINEMET is being administered, although dosage adjustments may be required. Interruption of Therapy Sporadic cases of a symptom complex resembling Neuroleptic Malignant Syndrome (NMS) have been associated with dose reductions and withdrawal of SINEMET. Patients should be observed carefully if abrupt reduction or discontinuation of SINEMET is required, especially if the patient is receiving neuroleptics. (See WARNINGS.) If general anesthesia is required, SINEMET may be continued as long as the patient is permitted to take fluids and medication by mouth. If therapy is interrupted temporarily, the patient should be observed for symptoms resembling NMS, and the usual daily dosage may be administered as soon as the patient is able to take oral medication.

DANOCRINE® Brand of DANAZOL CAPSULES, USP DESCRIPTION DANOCRINE, brand of danazol, is a synthetic steroid derived from ethisterone. It is a white to pale yellow crystalline powder, practically insoluble or insoluble in water, and sparingly soluble in alcohol. Chemically, danazol is 17α-Pregna-2,4-dien-20-yno [2,3-d]­ isoxazol-17-ol. The molecular formula is C22H27NO2. It has a molecular weight of 337.46 and the following structural formula: structural formula Danocrine capsules for oral administration contain 50 mg, 100 mg or 200 mg danazol. Inactive Ingredients: Corn Starch, Lactose, Magnesium Stearate, Talc. Capsules 50 mg, 100 mg and 200 mg contain D&C Yellow #10, FD&C Red #40, Gelatin, Silicon Dioxide, Sodium Lauryl Sulfate, Titanium Dioxide. The 50 mg and 200 mg capsules also contain D&C Red #28. CLINICAL PHARMACOLOGY DANOCRINE suppresses the pituitary-ovarian axis. This suppression is probably a combination of depressed hypothalamic-pituitary response to lowered estrogen production, the alteration of sex steroid metabolism, and interaction of danazol with sex hormone receptors. The only other demonstrable hormonal effect is weak androgenic activity. DANOCRINE depresses the output of both follicle-stimulating hormone (FSH) and luteinizing hormone (LH). Recent evidence suggests a direct inhibitory effect at gonadal sites and a binding of DANOCRINE to receptors of gonadal steroids at target organs. In addition, DANOCRINE has been shown to significantly decrease IgG, IgM and IgA levels, as well as phospholipid and IgG isotope autoantibodies in patients with endometriosis and associated elevations of autoantibodies, suggesting this could be another mechanism by which it facilitates regression of the disease. 1 Reference ID: 3061327 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda In the treatment of endometriosis, DANOCRINE alters the normal and ectopic endometrial tissue so that it becomes inactive and atrophic. Complete resolution of endometrial lesions occurs in the majority of cases. Changes in vaginal cytology and cervical mucus reflect the suppressive effect of DANOCRINE on the pituitary-ovarian axis. In the treatment of fibrocystic breast disease, DANOCRINE usually produces partial to complete disappearance of nodularity and complete relief of pain and tenderness. Changes in the menstrual pattern may occur. Generally, the pituitary-suppressive action of DANOCRINE is reversible. Ovulation and cyclic bleeding usually return within 60 to 90 days when therapy with DANOCRINE is discontinued. In the treatment of hereditary angioedema, DANOCRINE at effective doses prevents attacks of the disease characterized by episodic edema of the abdominal viscera, extremities, face, and airway which may be disabling and, if the airway is involved, fatal. In addition, DANOCRINE corrects partially or completely the primary biochemical abnormality of hereditary angioedema by increasing the levels of the deficient C1 esterase inhibitor (C1EI). As a result of this action the serum levels of the C4 component of the complement system are also increased. Pharmacokinetics Absorption: After oral administration of a 400 mg dose to healthy male volunteers, peak plasma concentrations of danazol are reached between 2 and 8 hours, with a median Tmax value of 4 hours. Steady state conditions are observed following 6 days of twice daily dosing of DANOCRINE. The pharmacokinetic parameters for DANOCRINE after administering a 400 mg oral dose to healthy males are summarized in the following table: Parameters Mean ± SD (n=15) Cmax (ng/mL) 69.6 ± 29.9 Tmax (h) 2.47 ± 1.62 AUC0-∞ (ng*h/mL) 601 ± 181 t1/2 (h) 9.70 ± 3.29 Total Body Clearance (L/h) 727 ± 221 The pharmacokinetic parameters for DANOCRINE after oral administration of 100, 200 and 400 mg single doses to healthy female volunteers are summarized in the following table: Reference ID: 3061327 2 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda Dose (mg) Mean Cmax ± SD (ng/mL) Mean Tmax (h) Mean AUC0-∞ ± SD (ng*h/mL) Fasting Fed Fasting Fed Fasting Fed 100 45.9 ±23.9 113.8 ± 46.0 1-8 2-6 484 ± 263 741 ± 265 200 63.8 ± 27.7 159 ± 57.3 1-6 2-4 681 ± 363 1252 ± 307 400 60.4 ± 30.0 253.7 ± 105.5 1-6 2-4 754 ± 443 1851 ± 605 Dose proportionality: Bioavailability studies indicate that blood levels do not increase proportionally with increases in the administered dose. Single dose administration of DANOCRINE in healthy female volunteers found that a 4­ fold increase in dose produced only a 1.6 and 2.5-fold increase in AUC and a 1.3 and 2.2­ fold increase in Cmax in the fasted and fed state, respectively. A similar degree of non-dose proportionality was observed at steady state. Food Effect: Single dose administration of 100 mg and 200 mg capsules of DANOCRINE to female volunteers showed that both the extent of availability and the maximum plasma concentration increased by 3 to 4 fold, respectively, following a meal (> 30 grams of fat), when compared to the fasted state. Further, food also delayed mean time to peak concentration of DANOCRINE by about 30 minutes. Even after multiple dosing under less extreme food/fasting conditions, there remained approximately a 2 to 2.5 fold difference in bioavailability between the fed and fasted states. Distribution: Danazol is lipophilic and can partition into cell membranes, indicating the likelihood of distribution into deep tissue compartments. Metabolism and Excretion: Danazol appears to be metabolized and the metabolites are eliminated by renal and fecal pathways. The two primary metabolites excreted in the urine are 2-hydroxymethyl danazol and ethisterone. At least ten different products were identified in feces. The reported elimination half-life of danazol is variable across studies. The mean half-life of danazol in healthy males is 9.7 h. After 6 months of 200 mg three times a day dosing in endometriosis patients, the half-life of danazol was reported as 23.7 hours. INDICATIONS AND USAGE Endometriosis. DANOCRINE is indicated for the treatment of endometriosis amenable to hormonal management. Fibrocystic Breast Disease. Most cases of symptomatic fibrocystic breast disease may be treated by simple measures (e.g., padded brassieres and analgesics). Reference ID: 3061327 3 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda In infrequent patients, symptoms of pain and tenderness may be severe enough to warrant treatment by suppression of ovarian function. DANOCRINE is usually effective in decreasing nodularity, pain, and tenderness. It should be stressed to the patient that this treatment is not innocuous in that it involves considerable alterations of hormone levels and that recurrence of symptoms is very common after cessation of therapy. Hereditary Angioedema. DANOCRINE is indicated for the prevention of attacks of angioedema of all types (cutaneous, abdominal, laryngeal) in males and females. CONTRAINDICATIONS DANOCRINE should not be administered to patients with: 1. Undiagnosed abnormal genital bleeding. 2. Markedly impaired hepatic, renal, or cardiac function. 3. Pregnancy. (See WARNINGS.) 4. Breast feeding. 5. Porphyria−DANOCRINE can induce ALA synthetase activity and hence porphyrin metabolism. 6. Androgen-dependent tumor. 7. Active thrombosis or thromboembolic disease and history of such events. 8. Hypersensitivity to danazol. WARNINGS Use of danazol in pregnancy is contraindicated. A sensitive test (e.g., beta subunit test if available) capable of determining early pregnancy is recommended immediately prior to start of therapy. Additionally a non-hormonal method of contraception should be used during therapy. If a patient becomes pregnant while taking danazol, administration of the drug should be discontinued and the patient should be apprised of the potential risk to the fetus. Exposure to danazol in utero may result in androgenic effects on the female fetus; reports of clitoral hypertrophy, labial fusion, urogenital sinus defect, vaginal atresia, and ambiguous genitalia have been received. (See PRECAUTIONS: Pregnancy, Teratogenic Effects.) Thromboembolism, thrombotic and thrombophlebitic events including sagittal sinus thrombosis and life-threatening or fatal strokes have been reported. Experience with long-term therapy with danazol is limited. Peliosis hepatis and benign hepatic adenoma have been observed with long-term use. Peliosis hepatis and hepatic adenoma may be silent until complicated by acute, potentially life-threatening intraabdominal hemorrhage. The physician therefore should be alert to this possibility. Attempts should be made to determine the lowest dose that will provide adequate protection. If the drug was begun at a time of exacerbation of hereditary angioneurotic edema due to trauma, stress or other cause, periodic attempts to decrease or withdraw therapy should be considered. Danazol has been associated with several cases of benign intracranial hypertension also 4 Reference ID: 3061327 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda known as pseudotumor cerebri. Early signs and symptoms of benign intracranial hypertension include papilledema, headache, nausea and vomiting, and visual disturbances. Patients with these symptoms should be screened for papilledema and, if present, the patients should be advised to discontinue danazol immediately and be referred to a neurologist for further diagnosis and care. A temporary alteration of lipoproteins in the form of decreased high density lipoproteins and possibly increased low density lipoproteins has been reported during danazol therapy. These alterations may be marked, and prescribers should consider the potential impact on the risk of atherosclerosis and coronary artery disease in accordance with the potential benefit of the therapy to the patient. Before initiating therapy of fibrocystic breast disease with DANOCRINE, carcinoma of the breast should be excluded. However, nodularity, pain, tenderness due to fibrocystic breast disease may prevent recognition of underlying carcinoma before treatment is begun. Therefore, if any nodule persists or enlarges during treatment, carcinoma should be considered and ruled out. Patients should be watched closely for signs of androgenic effects some of which may not be reversible even when drug administration is stopped. PRECAUTIONS Because DANOCRINE may cause some degree of fluid retention, conditions that might be influenced by this factor, such as epilepsy, migraine, or cardiac or renal dysfunction, polycythemia and hypertension require careful observation. Use with caution in patients with diabetes mellitus. Since hepatic dysfunction manifested by modest increases in serum transaminases levels has been reported in patients treated with DANOCRINE, periodic liver function tests should be performed (see WARNINGS and ADVERSE REACTIONS). Administration of danazol has been reported to cause exacerbation of the manifestations of acute intermittent porphyria. (See CONTRAINDICATIONS.) Laboratory monitoring of the hematologic state should be considered. Drug Interactions: Prolongation of prothrombin time occurs in patients stabilized on warfarin. Therapy with danazol may cause an increase in carbamazepine levels in patients taking both drugs. Danazol can cause insulin resistance. Caution should be exercised when used with antidiabetic drugs. Reference ID: 3061327 5 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda Danazol may raise the plasma levels of cyclosporin and tacrolimus, leading to an increase of the renal toxicity of these drugs. Monitoring of systemic concentrations of these drugs and appropriate dose adjustments may be needed when used concomitantly with danazol. Danazol can increase the calcemic response to synthetic vitamin D analogs in primary hypoparathyroidism. The risk of myopathy and rhabdomyolysis is increased by concomitant administration of danazol with statins such as simvastatin, atorvastatin and lovastatin. Caution should be exercised if used concomitantly. Consult the product labeling for statin drugs for specific information on dose restrictions in presence of danazol. Laboratory Tests: Danazol treatment may interfere with laboratory determinations of testosterone, androstenedione and dehydroepiandrosterone. Other metabolic events include a reduction in thyroid binding globulin and T4 with increased uptake of T3, but without disturbance of thyroid stimulating hormone or of free thyroxin index. Carcinogenesis, Mutagenesis, Impairment of Fertility: Current data are insufficient to assess the carcinogenicity of danazol. Pregnancy, Teratogenic Effects: (See CONTRAINDICATIONS.) Pregnancy Category X. DANOCRINE administered orally to pregnant rats from the 6th through the 15th day of gestation at doses up to 250 mg/kg/day (7-15 times the human dose) did not result in drug-induced embryotoxicity or teratogenicity, nor difference in litter size, viability or weight of offspring compared to controls. In rabbits, the administration of DANOCRINE on days 6-18 of gestation at doses of 60 mg/kg/day and above (2-4 times the human dose) resulted in inhibition of fetal development. Nursing Mothers: (See CONTRAINDICATIONS.) Pediatric Use: Safety and effectiveness in pediatric patients have not been established. Geriatric Use: Clinical studies of DANOCRINE did not include sufficient numbers of subjects aged 65 and over to determine the safety and effectiveness of Danocrine in elderly patients. ADVERSE REACTIONS The following events have been reported in association with the use of DANOCRINE: Androgen like effects include weight gain, acne and seborrhea. Mild hirsutism, edema, hair loss, voice change, which may take the form of hoarseness, sore throat or of instability or deepening of pitch, may occur and may persist after cessation of therapy. Hypertrophy of the clitoris is rare. Other possible endocrine effects are menstrual disturbances including spotting, alteration of the timing of the cycle and amenorrhea. Although cyclical bleeding and ovulation usually 6 Reference ID: 3061327 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda return within 60-90 days after discontinuation of therapy with DANOCRINE, persistent amenorrhea has occasionally been reported. Flushing, sweating, vaginal dryness and irritation and reduction in breast size, may reflect lowering of estrogen. Nervousness and emotional lability have been reported. In the male a modest reduction in spermatogenesis may be evident during treatment. Abnormalities in semen volume, viscosity, sperm count, and motility may occur in patients receiving long- term therapy. Hepatic dysfunction, as evidenced by reversible elevated serum enzymes and/or jaundice, has been reported in patients receiving a daily dosage of DANOCRINE of 400 mg or more. It is recommended that patients receiving DANOCRINE be monitored for hepatic dysfunction by laboratory tests and clinical observation. Serious hepatic toxicity including cholestatic jaundice, peliosis hepatis, and hepatic adenoma have been reported. (See WARNINGS and PRECAUTIONS.) Abnormalities in laboratory tests may occur during therapy with DANOCRINE including CPK, glucose tolerance, glucagon, thyroid binding globulin, sex hormone binding globulin, other plasma proteins, lipids and lipoproteins. The following reactions have been reported, a causal relationship to the administration of DANOCRINE has neither been confirmed nor refuted; allergic: urticaria, pruritus and rarely, nasal congestion; CNS effects: headache, nervousness and emotional lability, dizziness and fainting, depression, fatigue, sleep disorders, tremor, paresthesias, weakness, visual disturbances, and rarely, benign intracranial hypertension, anxiety, changes in appetite, chills, and rarely convulsions, Guillain-Barre syndrome; gastrointestinal: gastroenteritis, nausea, vomiting, constipation, and rarely, pancreatitis and splenic peliosis; musculoskeletal: muscle cramps or spasms, or pains, joint pain, joint lockup, joint swelling, pain in back, neck, or extremities, and rarely, carpal tunnel syndrome which may be secondary to fluid retention; genitourinary: hematuria, prolonged posttherapy amenorrhea; hematologic: an increase in red cell and platelet count. Reversible erythrocytosis, leukocytosis or polycythemia may be provoked. Eosinophilia, leukopenia and thrombocytopenia have also been noted. Skin: rashes (maculopapular, vesicular, papular, purpuric, petechial), and rarely, sun sensitivity, Stevens-Johnson syndrome and erythema multiforme; other: increased insulin requirements in diabetic patients, change in libido, myocardial infarction, palpitation, tachycardia, elevation in blood pressure, interstitial pneumonitis, and rarely, cataracts, bleeding gums, fever, pelvic pain, nipple discharge. Malignant liver tumors have been reported in rare instances, after long-term use. DOSAGE AND ADMINISTRATION Endometriosis. In moderate to severe disease, or in patients infertile due to endometriosis, a starting dose of 800 mg given in two divided doses is recommended. Amenorrhea and rapid response to painful symptoms is best achieved at this dosage level. Gradual downward titration to a dose sufficient to maintain amenorrhea may be considered depending upon patient response. For mild cases, an initial daily dose of 200 mg to 400 mg given in two 7 Reference ID: 3061327 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda divided doses is recommended and may be adjusted depending on patient response. Therapy should begin during menstruation. Otherwise, appropriate tests should be performed to ensure that the patient is not pregnant while on therapy with DANOCRINE. (See CONTRAINDICATIONS and WARNINGS.) It is essential that therapy continue uninterrupted for 3 to 6 months but may be extended to 9 months if necessary. After termination of therapy, if symptoms recur, treatment can be reinstituted. Fibrocystic Breast Disease. The total daily dosage of DANOCRINE for fibrocystic breast disease ranges from 100 mg to 400 mg given in two divided doses depending upon patient response. Therapy should begin during menstruation. Otherwise, appropriate tests should be performed to ensure that the patient is not pregnant while on therapy with DANOCRINE. A nonhormonal method of contraception is recommended when DANOCRINE is administered at this dose, since ovulation may not be suppressed. In most instances, breast pain and tenderness are significantly relieved by the first month and eliminated in 2 to 3 months. Usually elimination of nodularity requires 4 to 6 months of uninterrupted therapy. Regular menstrual patterns irregular menstrual patterns and amenorrhea each occur in approximately one-third of patients treated with 100 mg of DANOCRINE. Irregular menstrual patterns and amenorrhea are observed more frequently with higher doses. Clinical studies have demonstrated that 50% of patients may show evidence of recurrence of symptoms within one year. In this event, treatment may be reinstated. Hereditary Angioedema. The dosage requirements for continuous treatment of hereditary angioedema with DANOCRINE should be individualized on the basis of the clinical response of the patient. It is recommended that the patient be started on 200 mg, two or three times a day. After a favorable initial response is obtained in terms of prevention of episodes of edematous attacks, the proper continuing dosage should be determined by decreasing the dosage by 50% or less at intervals of one to three months or longer if frequency of attacks prior to treatment dictates. If an attack occurs, the daily dosage may be increased by up to 200 mg. During the dose adjusting phase, close monitoring of the patient’s response is indicated, particularly if the patient has a history of airway involvement.

In the treatment of hereditary angioedema, DANOCRINE at effective doses prevents attacks of the disease characterized by episodic edema of the abdominal viscera, extremities, face, and airway which may be disabling and, if the airway is involved, fatal. In addition, DANOCRINE corrects partially or completely the primary biochemical abnormality of hereditary angioedema by increasing the levels of the deficient C1 esterase inhibitor (C1EI). As a result of this action the serum levels of the C4 component of the complement system are also increased. Pharmacokinetics Absorption: After oral administration of a 400 mg dose to healthy male volunteers, peak plasma concentrations of danazol are reached between 2 and 8 hours, with a median Tmax value of 4 hours. Steady state conditions are observed following 6 days of twice daily dosing of DANOCRINE. The pharmacokinetic parameters for DANOCRINE after administering a 400 mg oral dose to healthy males are summarized in the following table: Parameters Mean ± SD (n=15) Cmax (ng/mL) 69.6 ± 29.9 Tmax (h) 2.47 ± 1.62 AUC0-∞ (ng*h/mL) 601 ± 181 t1/2 (h) 9.70 ± 3.29 Total Body Clearance (L/h) 727 ± 221 The pharmacokinetic parameters for DANOCRINE after oral administration of 100, 200 and 400 mg single doses to healthy female volunteers are summarized in the following table: Reference ID: 3061327 2 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda Dose (mg) Mean Cmax ± SD (ng/mL) Mean Tmax (h) Mean AUC0-∞ ± SD (ng*h/mL) Fasting Fed Fasting Fed Fasting Fed 100 45.9 ±23.9 113.8 ± 46.0 1-8 2-6 484 ± 263 741 ± 265 200 63.8 ± 27.7 159 ± 57.3 1-6 2-4 681 ± 363 1252 ± 307 400 60.4 ± 30.0 253.7 ± 105.5 1-6 2-4 754 ± 443 1851 ± 605 Dose proportionality: Bioavailability studies indicate that blood levels do not increase proportionally with increases in the administered dose. Single dose administration of DANOCRINE in healthy female volunteers found that a 4­ fold increase in dose produced only a 1.6 and 2.5-fold increase in AUC and a 1.3 and 2.2­ fold increase in Cmax in the fasted and fed state, respectively. A similar degree of non-dose proportionality was observed at steady state. Food Effect: Single dose administration of 100 mg and 200 mg capsules of DANOCRINE to female volunteers showed that both the extent of availability and the maximum plasma concentration increased by 3 to 4 fold, respectively, following a meal (> 30 grams of fat), when compared to the fasted state. Further, food also delayed mean time to peak concentration of DANOCRINE by about 30 minutes. Even after multiple dosing under less extreme food/fasting conditions, there remained approximately a 2 to 2.5 fold difference in bioavailability between the fed and fasted states. Distribution: Danazol is lipophilic and can partition into cell membranes, indicating the likelihood of distribution into deep tissue compartments. Metabolism and Excretion: Danazol appears to be metabolized and the metabolites are eliminated by renal and fecal pathways. The two primary metabolites excreted in the urine are 2-hydroxymethyl danazol and ethisterone. At least ten different products were identified in feces. The reported elimination half-life of danazol is variable across studies. The mean half-life of danazol in healthy males is 9.7 h. After 6 months of 200 mg three times a day dosing in endometriosis patients, the half-life of danazol was reported as 23.7 hours. INDICATIONS AND USAGE Endometriosis. DANOCRINE is indicated for the treatment of endometriosis amenable to hormonal management. Fibrocystic Breast Disease. Most cases of symptomatic fibrocystic breast disease may be treated by simple measures (e.g., padded brassieres and analgesics). Reference ID: 3061327 3 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda In infrequent patients, symptoms of pain and tenderness may be severe enough to warrant treatment by suppression of ovarian function. DANOCRINE is usually effective in decreasing nodularity, pain, and tenderness. It should be stressed to the patient that this treatment is not innocuous in that it involves considerable alterations of hormone levels and that recurrence of symptoms is very common after cessation of therapy. Hereditary Angioedema. DANOCRINE is indicated for the prevention of attacks of angioedema of all types (cutaneous, abdominal, laryngeal) in males and females. CONTRAINDICATIONS DANOCRINE should not be administered to patients with: 1. Undiagnosed abnormal genital bleeding. 2. Markedly impaired hepatic, renal, or cardiac function. 3. Pregnancy. (See WARNINGS.) 4. Breast feeding. 5. Porphyria−DANOCRINE can induce ALA synthetase activity and hence porphyrin metabolism. 6. Androgen-dependent tumor. 7. Active thrombosis or thromboembolic disease and history of such events. 8. Hypersensitivity to danazol. WARNINGS Use of danazol in pregnancy is contraindicated. A sensitive test (e.g., beta subunit test if available) capable of determining early pregnancy is recommended immediately prior to start of therapy. Additionally a non-hormonal method of contraception should be used during therapy. If a patient becomes pregnant while taking danazol, administration of the drug should be discontinued and the patient should be apprised of the potential risk to the fetus. Exposure to danazol in utero may result in androgenic effects on the female fetus; reports of clitoral hypertrophy, labial fusion, urogenital sinus defect, vaginal atresia, and ambiguous genitalia have been received. (See PRECAUTIONS: Pregnancy, Teratogenic Effects.) Thromboembolism, thrombotic and thrombophlebitic events including sagittal sinus thrombosis and life-threatening or fatal strokes have been reported. Experience with long-term therapy with danazol is limited. Peliosis hepatis and benign hepatic adenoma have been observed with long-term use. Peliosis hepatis and hepatic adenoma may be silent until complicated by acute, potentially life-threatening intraabdominal hemorrhage. The physician therefore should be alert to this possibility. Attempts should be made to determine the lowest dose that will provide adequate protection. If the drug was begun at a time of exacerbation of hereditary angioneurotic edema due to trauma, stress or other cause, periodic attempts to decrease or withdraw therapy should be considered. Danazol has been associated with several cases of benign intracranial hypertension also 4 Reference ID: 3061327 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda known as pseudotumor cerebri. Early signs and symptoms of benign intracranial hypertension include papilledema, headache, nausea and vomiting, and visual disturbances. Patients with these symptoms should be screened for papilledema and, if present, the patients should be advised to discontinue danazol immediately and be referred to a neurologist for further diagnosis and care. A temporary alteration of lipoproteins in the form of decreased high density lipoproteins and possibly increased low density lipoproteins has been reported during danazol therapy. These alterations may be marked, and prescribers should consider the potential impact on the risk of atherosclerosis and coronary artery disease in accordance with the potential benefit of the therapy to the patient. Before initiating therapy of fibrocystic breast disease with DANOCRINE, carcinoma of the breast should be excluded. However, nodularity, pain, tenderness due to fibrocystic breast disease may prevent recognition of underlying carcinoma before treatment is begun. Therefore, if any nodule persists or enlarges during treatment, carcinoma should be considered and ruled out. Patients should be watched closely for signs of androgenic effects some of which may not be reversible even when drug administration is stopped. PRECAUTIONS Because DANOCRINE may cause some degree of fluid retention, conditions that might be influenced by this factor, such as epilepsy, migraine, or cardiac or renal dysfunction, polycythemia and hypertension require careful observation. Use with caution in patients with diabetes mellitus. Since hepatic dysfunction manifested by modest increases in serum transaminases levels has been reported in patients treated with DANOCRINE, periodic liver function tests should be performed (see WARNINGS and ADVERSE REACTIONS). Administration of danazol has been reported to cause exacerbation of the manifestations of acute intermittent porphyria. (See CONTRAINDICATIONS.) Laboratory monitoring of the hematologic state should be considered. Drug Interactions: Prolongation of prothrombin time occurs in patients stabilized on warfarin. Therapy with danazol may cause an increase in carbamazepine levels in patients taking both drugs. Danazol can cause insulin resistance. Caution should be exercised when used with antidiabetic drugs. Reference ID: 3061327 5 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda Danazol may raise the plasma levels of cyclosporin and tacrolimus, leading to an increase of the renal toxicity of these drugs. Monitoring of systemic concentrations of these drugs and appropriate dose adjustments may be needed when used concomitantly with danazol. Danazol can increase the calcemic response to synthetic vitamin D analogs in primary hypoparathyroidism. The risk of myopathy and rhabdomyolysis is increased by concomitant administration of danazol with statins such as simvastatin, atorvastatin and lovastatin. Caution should be exercised if used concomitantly. Consult the product labeling for statin drugs for specific information on dose restrictions in presence of danazol. Laboratory Tests: Danazol treatment may interfere with laboratory determinations of testosterone, androstenedione and dehydroepiandrosterone. Other metabolic events include a reduction in thyroid binding globulin and T4 with increased uptake of T3, but without disturbance of thyroid stimulating hormone or of free thyroxin index. Carcinogenesis, Mutagenesis, Impairment of Fertility: Current data are insufficient to assess the carcinogenicity of danazol. Pregnancy, Teratogenic Effects: (See CONTRAINDICATIONS.) Pregnancy Category X. DANOCRINE administered orally to pregnant rats from the 6th through the 15th day of gestation at doses up to 250 mg/kg/day (7-15 times the human dose) did not result in drug-induced embryotoxicity or teratogenicity, nor difference in litter size, viability or weight of offspring compared to controls. In rabbits, the administration of DANOCRINE on days 6-18 of gestation at doses of 60 mg/kg/day and above (2-4 times the human dose) resulted in inhibition of fetal development. Nursing Mothers: (See CONTRAINDICATIONS.) Pediatric Use: Safety and effectiveness in pediatric patients have not been established. Geriatric Use: Clinical studies of DANOCRINE did not include sufficient numbers of subjects aged 65 and over to determine the safety and effectiveness of Danocrine in elderly patients. ADVERSE REACTIONS The following events have been reported in association with the use of DANOCRINE: Androgen like effects include weight gain, acne and seborrhea. Mild hirsutism, edema, hair loss, voice change, which may take the form of hoarseness, sore throat or of instability or deepening of pitch, may occur and may persist after cessation of therapy. Hypertrophy of the clitoris is rare. Other possible endocrine effects are menstrual disturbances including spotting, alteration of the timing of the cycle and amenorrhea. Although cyclical bleeding and ovulation usually 6 Reference ID: 3061327 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda return within 60-90 days after discontinuation of therapy with DANOCRINE, persistent amenorrhea has occasionally been reported. Flushing, sweating, vaginal dryness and irritation and reduction in breast size, may reflect lowering of estrogen. Nervousness and emotional lability have been reported. In the male a modest reduction in spermatogenesis may be evident during treatment. Abnormalities in semen volume, viscosity, sperm count, and motility may occur in patients receiving long- term therapy. Hepatic dysfunction, as evidenced by reversible elevated serum enzymes and/or jaundice, has been reported in patients receiving a daily dosage of DANOCRINE of 400 mg or more. It is recommended that patients receiving DANOCRINE be monitored for hepatic dysfunction by laboratory tests and clinical observation. Serious hepatic toxicity including cholestatic jaundice, peliosis hepatis, and hepatic adenoma have been reported. (See WARNINGS and PRECAUTIONS.) Abnormalities in laboratory tests may occur during therapy with DANOCRINE including CPK, glucose tolerance, glucagon, thyroid binding globulin, sex hormone binding globulin, other plasma proteins, lipids and lipoproteins. The following reactions have been reported, a causal relationship to the administration of DANOCRINE has neither been confirmed nor refuted; allergic: urticaria, pruritus and rarely, nasal congestion; CNS effects: headache, nervousness and emotional lability, dizziness and fainting, depression, fatigue, sleep disorders, tremor, paresthesias, weakness, visual disturbances, and rarely, benign intracranial hypertension, anxiety, changes in appetite, chills, and rarely convulsions, Guillain-Barre syndrome; gastrointestinal: gastroenteritis, nausea, vomiting, constipation, and rarely, pancreatitis and splenic peliosis; musculoskeletal: muscle cramps or spasms, or pains, joint pain, joint lockup, joint swelling, pain in back, neck, or extremities, and rarely, carpal tunnel syndrome which may be secondary to fluid retention; genitourinary: hematuria, prolonged posttherapy amenorrhea; hematologic: an increase in red cell and platelet count. Reversible erythrocytosis, leukocytosis or polycythemia may be provoked. Eosinophilia, leukopenia and thrombocytopenia have also been noted. Skin: rashes (maculopapular, vesicular, papular, purpuric, petechial), and rarely, sun sensitivity, Stevens-Johnson syndrome and erythema multiforme; other: increased insulin requirements in diabetic patients, change in libido, myocardial infarction, palpitation, tachycardia, elevation in blood pressure, interstitial pneumonitis, and rarely, cataracts, bleeding gums, fever, pelvic pain, nipple discharge. Malignant liver tumors have been reported in rare instances, after long-term use. DOSAGE AND ADMINISTRATION Endometriosis. In moderate to severe disease, or in patients infertile due to endometriosis, a starting dose of 800 mg given in two divided doses is recommended. Amenorrhea and rapid response to painful symptoms is best achieved at this dosage level. Gradual downward titration to a dose sufficient to maintain amenorrhea may be considered depending upon patient response. For mild cases, an initial daily dose of 200 mg to 400 mg given in two 7 Reference ID: 3061327 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda divided doses is recommended and may be adjusted depending on patient response. Therapy should begin during menstruation. Otherwise, appropriate tests should be performed to ensure that the patient is not pregnant while on therapy with DANOCRINE. (See CONTRAINDICATIONS and WARNINGS.) It is essential that therapy continue uninterrupted for 3 to 6 months but may be extended to 9 months if necessary. After termination of therapy, if symptoms recur, treatment can be reinstituted. Fibrocystic Breast Disease. The total daily dosage of DANOCRINE for fibrocystic breast disease ranges from 100 mg to 400 mg given in two divided doses depending upon patient response. Therapy should begin during menstruation. Otherwise, appropriate tests should be performed to ensure that the patient is not pregnant while on therapy with DANOCRINE. A nonhormonal method of contraception is recommended when DANOCRINE is administered at this dose, since ovulation may not be suppressed. In most instances, breast pain and tenderness are significantly relieved by the first month and eliminated in 2 to 3 months. Usually elimination of nodularity requires 4 to 6 months of uninterrupted therapy. Regular menstrual patterns irregular menstrual patterns and amenorrhea each occur in approximately one-third of patients treated with 100 mg of DANOCRINE. Irregular menstrual patterns and amenorrhea are observed more frequently with higher doses. Clinical studies have demonstrated that 50% of patients may show evidence of recurrence of symptoms within one year. In this event, treatment may be reinstated. Hereditary Angioedema. The dosage requirements for continuous treatment of hereditary angioedema with DANOCRINE should be individualized on the basis of the clinical response of the patient. It is recommended that the patient be started on 200 mg, two or three times a day. After a favorable initial response is obtained in terms of prevention of episodes of edematous attacks, the proper continuing dosage should be determined by decreasing the dosage by 50% or less at intervals of one to three months or longer if frequency of attacks prior to treatment dictates. If an attack occurs, the daily dosage may be increased by up to 200 mg. During the dose adjusting phase, close monitoring of the patient’s response is indicated, particularly if the patient has a history of airway involvement.

---------- HALOG®(Halcinonide Cream, USP) 0.1% Page 1 of 6 HALOG - halcinonide cream  ® HALOG (Halcinonide Cream, USP) 0.1% For Topical Use Only. Not For Ophthalmic, Oral or Intravaginal Use. DESCRIPTION The topical corticosteroids constitute a class of primarily synthetic steroids used as anti­ inflammatory and antipruritic agents. The steroids in this class include halcinonide. Halcinonide is designated chemically as 21-Chloro-9-fluoro-11β,16α, 17-trihydroxypregn-4-ene-3,20-dione cyclic 16,17-acetal with acetone. Graphic formula: Each gram of 0.1% HALOG (Halcinonide Cream, USP) contains 1 mg halcinonide in a specially formulated cream base consisting of cetyl alcohol, dimethicone 350, glyceryl monostearate NF XII, isopropyl palmitate, polysorbate 60, propylene glycol, purified water, and titanium dioxide. Structural Formula CLINICAL PHARMACOLOGY Topical corticosteroids share anti-inflammatory, antipruritic and vasoconstrictive actions. The mechanism of anti-inflammatory activity of the topical corticosteroids is unclear. Various laboratory methods, including vasoconstrictor assays, are used to compare and predict potencies and/or clinical efficacies of the topical corticosteroids. There is some evidence to suggest that a recognizable correlation exists between vasoconstrictor potency and therapeutic efficacy in man. Pharmacokinetics The extent of percutaneous absorption of topical corticosteroids is determined by many factors including the vehicle, the integrity of the epidermal barrier, and the use of occlusive dressings. Topical corticosteroids can be absorbed from normal intact skin. Inflammation and/or other disease processes in the skin increase percutaneous absorption. Occlusive dressings substantially increase the percutaneous absorption of topical corticosteroids. Thus, occlusive dressings may be a valuable therapeutic adjunct for treatment of resistant dermatoses (see DOSAGE AND ADMINISTRATION). file://\\Fdswa150\nonectd\N17556\S_038\2009-02-09\NDA 17-556, Halog® (halcinonide)... 6/10/2009 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda HALOG®(Halcinonide Cream, USP) 0.1% Page 2 of 6 Once absorbed through the skin, topical corticosteroids are handled through pharmacokinetic pathways similar to systemically administered corticosteroids. Corticosteroids are bound to plasma proteins in varying degrees. Corticosteroids are metabolized primarily in the liver and are then excreted by the kidneys. Some of the topical corticosteroids and their metabolites are also excreted into the bile. INDICATIONS AND USAGE HALOG (Halcinonide Cream, USP) 0.1% is indicated for the relief of the inflammatory and pruritic manifestations of corticosteroid-responsive dermatoses. CONTRAINDICATIONS Topical corticosteroids are contraindicated in those patients with a history of hypersensitivity to any of the components of the preparations. PRECAUTIONS General Systemic absorption of topical corticosteroids has produced reversible hypothalamic-pituitary­ adrenal (HPA) axis suppression, manifestations of Cushing’s syndrome, hyperglycemia, and glucosuria in some patients. Conditions which augment systemic absorption include the application of the more potent steroids, use over large surface areas, prolonged use, and the addition of occlusive dressings. Therefore, patients receiving a large dose of any potent topical steroid applied to a large surface area or under an occlusive dressing should be evaluated periodically for evidence of HPA axis suppression by using the urinary free cortisol and ACTH stimulation tests, and for impairment of thermal homeostasis. If HPA axis suppression or elevation of the body temperature occurs, an attempt should be made to withdraw the drug, to reduce the frequency of application, substitute a less potent steroid, or use a sequential approach when utilizing the occlusive technique. Recovery of HPA axis function and thermal homeostasis are generally prompt and complete upon discontinuation of the drug. Infrequently, signs and symptoms of steroid withdrawal may occur, requiring supplemental systemic corticosteroids. Occasionally, a patient may develop a sensitivity reaction to a particular occlusive dressing material or adhesive and a substitute material may be necessary. Children may absorb proportionally larger amounts of topical corticosteroids and thus be more susceptible to systemic toxicity (see PRECAUTIONS: Pediatric Use). If irritation develops, topical corticosteroids should be discontinued and appropriate therapy instituted. In the presence of dermatological infections, the use of an appropriate antifungal or antibacterial agent should be instituted. If a favorable response does not occur promptly, the corticosteroid should be discontinued until the infection has been adequately controlled. The preparation is not for ophthalmic, oral, or intravaginal use. file://\\Fdswa150\nonectd\N17556\S_038\2009-02-09\NDA 17-556, Halog® (halcinonide)... 6/10/2009 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda HALOG®(Halcinonide Cream, USP) 0.1% Page 3 of 6 Information for the Patient Patients using topical corticosteroids should receive the following information and instructions: • This medication is to be used as directed by the physician. It is for dermatologic use only. Avoid contact with the eyes. • Patients should be advised not to use this medication for any disorder other than for which it was prescribed. • The treated skin area should not be bandaged or otherwise covered or wrapped as to be occlusive unless directed by the physician. • Patients should report any signs of local adverse reactions especially under occlusive dressing. • Parents of pediatric patients should be advised not to use tight-fitting diapers or plastic pants on a child being treated in the diaper area, as these garments may constitute occlusive dressings. Laboratory Tests A urinary free cortisol test and ACTH stimulation test may be helpful in evaluating HPA axis suppression. Carcinogenesis, Mutagenesis, and Impairment of Fertility Long-term animal studies have not been performed to evaluate the carcinogenic potential or the effect on fertility of topical corticosteroids. Studies to determine mutagenicity with prednisolone and hydrocortisone showed negative results. Pregnancy Teratogenic Effects: Category C Corticosteroids are generally teratogenic in laboratory animals when administered systemically at relatively low dosage levels. The more potent corticosteroids have been shown to be teratogenic after dermal application in laboratory animals. There are no adequate and well- controlled studies in pregnant women on teratogenic effects from topically applied corticosteroids. Therefore, topical corticosteroids should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus. Drugs of this class should not be used extensively on pregnant patients, in large amounts, or for prolonged periods of time. Nursing Mothers It is not known whether topical administration of corticosteroids could result in sufficient systemic absorption to produce detectable quantities in breast milk. Systemically administered corticosteroids are secreted into breast milk in quantities not likely to have a deleterious effect on the infant. Nevertheless, caution should be exercised when topical corticosteroids are administered to a nursing woman. file://\\Fdswa150\nonectd\N17556\S_038\2009-02-09\NDA 17-556, Halog® (halcinonide)... 6/10/2009 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda HALOG®(Halcinonide Cream, USP) 0.1% Page 4 of 6 Pediatric Use Pediatric patients may demonstrate greater susceptibility to topical corticosteroid-induced HPA axis suppression and Cushing’s syndrome than mature patients because of a larger skin surface area to body weight ratio. HPA axis suppression, Cushing’s syndrome, and intracranial hypertension have been reported in children receiving topical corticosteroids. Manifestations of adrenal suppression in children include linear growth retardation, delayed weight gain, low plasma cortisol levels, and absence of response to ACTH stimulation. Manifestations of intracranial hypertension include bulging fontanelles, headaches, and bilateral papilledema. Administration of topical corticosteroids to children should be limited to the least amount compatible with an effective therapeutic regimen. Chronic corticosteroid therapy may interfere with the growth and development of children. Geriatric Use Of approximately 3000 patients included in clinical studies of 0.1% HALOG CREAM, 14% were 60 years or older, while 4% were 70 years or older. No overall differences in safety were observed between these patients and younger patients. Efficacy data have not been evaluated for differences between elderly and younger patients. Other reported clinical experience has not identified differences in responses between the elderly and younger patients, but greater sensitivity of some older individuals cannot be ruled out. ADVERSE REACTIONS The following local adverse reactions are reported infrequently with topical corticosteroids, but may occur more frequently with the use of occlusive dressings (reactions are listed in an approximate decreasing order of occurrence): burning, itching, irritation, dryness, folliculitis, hypertrichosis, acneiform eruptions, hypopigmentation, perioral dermatitis, allergic contact dermatitis, maceration of the skin, secondary infection, skin atrophy, striae, and miliaria. OVERDOSAGE Topically applied corticosteroids can be absorbed in sufficient amounts to produce systemic effects (see PRECAUTIONS: General). DOSAGE AND ADMINISTRATION Apply the 0.1% HALOG (Halcinonide Cream, USP) to the affected area two to three times daily. Rub in gently. Occlusive Dressing Technique Occlusive dressings may be used for the management of psoriasis or other recalcitrant conditions. Gently rub a small amount of cream into the lesion until it disappears. Reapply the preparation leaving a thin coating on the lesion, cover with a pliable nonporous film, and seal the edges. If needed, additional moisture may be provided by covering the lesion with a dampened clean cotton cloth before the nonporous film is applied or by briefly wetting the affected area with water immediately prior to applying the medication. The frequency of changing dressings is best determined on an individual basis.

DITROPAN® (oxybutynin chloride) Tablets DESCRIPTION Each scored biconvex, engraved blue DITROPAN® (oxybutynin chloride) Tablet contains 5 mg of oxybutynin chloride. Chemically, oxybutynin chloride is d,l (racemic) 4-diethylamino-2-butynyl phenylcyclohexylglycolate hydrochloride. The empirical formula of oxybutynin chloride is C22H31NO3•HCl. The structural formula appears below: Structural Formula Oxybutynin chloride is a white crystalline solid with a molecular weight of 393.9. It is readily soluble in water and acids, but relatively insoluble in alkalis. DITROPAN Tablets also contain calcium stearate, FD&C Blue #1 Lake, lactose, and microcrystalline cellulose. DITROPAN Tablets are for oral administration. Therapeutic Category: Antispasmodic, anticholinergic. CLINICAL PHARMACOLOGY Oxybutynin chloride exerts a direct antispasmodic effect on smooth muscle and inhibits the muscarinic action of acetylcholine on smooth muscle. Oxybutynin chloride exhibits only one fifth of the anticholinergic activity of atropine on the rabbit detrusor muscle, but four to ten times the antispasmodic activity. No blocking effects occur at skeletal neuromuscular junctions or autonomic ganglia (antinicotinic effects). Oxybutynin chloride relaxes bladder smooth muscle. In patients with conditions characterized by involuntary bladder contractions, cystometric studies have demonstrated that oxybutynin chloride increases bladder (vesical) capacity, diminishes the frequency of uninhibited contractions of the detrusor muscle, and delays the initial desire to void. Oxybutynin chloride thus decreases urgency and the frequency of both incontinent episodes and voluntary urination. Antimuscarinic activity resides predominately in the R-isomer. A metabolite, desethyloxybutynin, has pharmacological activity similar to that of oxybutynin in in vitro studies. 1 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda Pharmacokinetics Absorption Following oral administration of DITROPAN, oxybutynin is rapidly absorbed achieving Cmax within an hour, following which plasma concentration decreases with an effective half-life of approximately 2 to 3 hours. The absolute bioavailability of oxybutynin is reported to be about 6% (range 1.6 to 10.9%) for the tablets. Wide interindividual variation in pharmacokinetic parameters is evident following oral administration of oxybutynin.

For current labeling information, please visit https://www.fda.gov/drugsatfda Food Effects Data in the literature suggests that oxybutynin solution co-administered with food resulted in a slight delay in absorption and an increase in its bioavailability by 25% (n=18). Distribution Plasma concentrations of oxybutynin decline biexponentially following intravenous or oral administration. The volume of distribution is 193 L after intravenous administration of 5 mg oxybutynin chloride. Metabolism Oxybutynin is metabolized primarily by the cytochrome P450 enzyme systems, particularly CYP3A4 found mostly in the liver and gut wall. Its metabolic products include phenylcyclohexylglycolic acid, which is pharmacologically inactive, and desethyloxybutynin, which is pharmacologically active. Excretion Oxybutynin is extensively metabolized by the liver, with less than 0.1% of the administered dose excreted unchanged in the urine. Also, less than 0.1% of the administered dose is excreted as the metabolite desethyloxybutynin. CLINICAL STUDIES DITROPAN was well tolerated in patients administered the drug in controlled studies of 30 days’ duration and in uncontrolled studies in which some of the patients received the drug for 2 years. INDICATIONS AND USAGE DITROPAN® (oxybutynin chloride) is indicated for the relief of symptoms of bladder instability associated with voiding in patients with uninhibited neurogenic or reflex neurogenic bladder (i.e., urgency, frequency, urinary leakage, urge incontinence, dysuria). CONTRAINDICATIONS DITROPAN® (oxybutynin chloride) is contraindicated in patients with urinary retention, gastric retention and other severe decreased gastrointestinal motility conditions, uncontrolled narrow-angle glaucoma and in patients who are at risk for these conditions. DITROPAN is also contraindicated in patients who have demonstrated hypersensitivity to the drug substance or other components of the product. 4 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda PRECAUTIONS Central Nervous System Effects Oxybutynin is associated with anticholinergic central nervous system (CNS) effects (See ADVERSE REACTIONS). A variety of CNS anticholinergic effects have been reported, including hallucinations, agitation, confusion and somnolence. Patients should be monitored for signs of anticholinergic CNS effects, particularly in the first few months after beginning treatment or increasing the dose. If a patient experiences anticholinergic CNS effects, dose reduction or drug discontinuation should be considered. DITROPAN should be used with caution in patients with preexisting dementia treated with cholinesterase inhibitors due to the risk of aggravation of symptoms. General DITROPAN® (oxybutynin chloride) should be used with caution in the frail elderly, in patients with hepatic or renal impairment, and in patients with myasthenia gravis. DITROPAN may aggravate the symptoms of hyperthyroidism, coronary heart disease, congestive heart failure, cardiac arrhythmias, hiatal hernia, tachycardia, hypertension, myasthenia gravis, and prostatic hypertrophy. Urinary Retention DITROPAN should be administered with caution to patients with clinically significant bladder outflow obstruction because of the risk of urinary retention (see CONTRAINDICATIONS). Gastrointestinal Disorders DITROPAN should be administered with caution to patients with gastrointestinal obstructive disorders because of the risk of gastric retention (see CONTRAINDICATIONS). Administration of DITROPAN to patients with ulcerative colitis may suppress intestinal motility to the point of producing a paralytic ileus and precipitate or aggravate toxic megacolon, a serious complication of the disease. DITROPAN, like other anticholinergic drugs, may decrease gastrointestinal motility and should be used with caution in patients with conditions such as ulcerative colitis, and intestinal atony. 5 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda DITROPAN should be used with caution in patients who have gastroesophageal reflux and/or who are concurrently taking drugs (such as bisphosphonates) that can cause or exacerbate esophagitis. Information for Patients Patients should be informed that heat prostration (fever and heat stroke due to decreased sweating) can occur when anticholinergics such as oxybutynin chloride are administered in the presence of high environmental temperature. Because anticholinergic agents such as oxybutynin may produce drowsiness (somnolence), or blurred vision, patients should be advised to exercise caution. Patients should be informed that alcohol may enhance the drowsiness caused by anticholinergic agents such as oxybutynin. Drug Interactions The concomitant use of oxybutynin with other anticholinergic drugs or with other agents which produce dry mouth, constipation, somnolence (drowsiness), and/or other anticholinergic-like effects may increase the frequency and/or severity of such effects. Anticholinergic agents may potentially alter the absorption of some concomitantly administered drugs due to anticholinergic effects on gastrointestinal motility. This may be of concern for drugs with a narrow therapeutic index. Mean oxybutynin chloride plasma concentrations were approximately 3-4 fold higher when DITROPAN was administered with ketoconazole, a potent CYP3A4 inhibitor. Other inhibitors of the cytochrome P450 3A4 enzyme system, such as antimycotic agents (e.g., itraconazole and miconazole) or macrolide antibiotics (e.g., erythromycin and clarithromycin), may alter oxybutynin mean pharmacokinetic parameters (i.e., Cmax and AUC). The clinical relevance of such potential interactions is not known. Caution should be used when such drugs are co-administered. Carcinogenesis, Mutagenesis, Impairment of Fertility A 24-month study in rats at dosages of oxybutynin chloride of 20, 80, and 160 mg/kg/day showed no evidence of carcinogenicity. These doses are approximately 6, 25, and 50 times the maximum human exposure, based on surface area. 6 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda Oxybutynin chloride showed no increase of mutagenic activity when tested in Schizosaccharomyces pompholiciformis, Saccharomyces cerevisiae and Salmonella typhimurium test systems. Reproduction studies using oxybutynin chloride in the hamster, rabbit, rat, and mouse have shown no definite evidence of impaired fertility. Pregnancy Category B. Reproduction studies using oxybutynin chloride in the hamster, rabbit, rat, and mouse have shown no definite evidence of impaired fertility or harm to the animal fetus. The safety of DITROPAN administered to women who are or who may become pregnant has not been established. Therefore, DITROPAN should not be given to pregnant women unless, in the judgment of the physician, the probable clinical benefits outweigh the possible hazards. Nursing Mothers It is not known whether this drug is excreted in human milk. Because many drugs are excreted in human milk, caution should be exercised when DITROPAN is administered to a nursing woman. Pediatric Use The safety and efficacy of DITROPAN administration have been demonstrated for pediatric patients 5 years of age and older (see DOSAGE AND ADMINISTRATION). The safety and efficacy of DITROPAN Tablets were studied in 30 children in a 24­ week, open-label trial. Patients were aged 5-15 years, all had symptoms of detrusor overactivity in association with a neurological condition (e.g., spina bifida), all used clean intermittent catheterization, and all were current users of oxybutynin chloride. Study results demonstrated that the administration of DITROPAN was associated with improvement in clinical and urodynamic parameters. At total daily doses ranging from 5 mg to 15 mg, treatment with DITROPAN Tablets was associated with an increase from baseline in mean urine volume per catheterization from 122 mL to 145 mL, an increase from baseline in mean urine volume after morning awakening from 148 mL to 168 mL, and an increase from baseline in the mean percentage of catheterizations without a leaking episode from 43% to 61%. Urodynamic results in these patients were consistent with the clinical results. Treatment with DITROPAN Tablets was associated with an increase from baseline in maximum cystometric capacity from 230 mL to 279 mL, a decrease from baseline in mean detrusor pressure at maximum cystometric capacity from 36 cm 7 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda T a b l e H20 to 33 cm H20, and a reduction in the percentage of patients demonstrating uninhibited detrusor contractions (of at least 15 cm H20) from 39% to 20%. As there is insufficient clinical data for pediatric populations under age 5, DITROPAN is not recommended for this age group. Geriatric Use Clinical studies of DITROPAN did not include sufficient numbers of subjects age 65 and over to determine whether they respond differently from younger patients. Other reported clinical experience has not identified differences in responses between healthy elderly and younger patients; however, a lower initial starting dose of 2.5 mg given 2 or 3 times a day has been recommended for the frail elderly due to a prolongation of the elimination half-life from 2-3 hours to 5 hours.2, 3, 4 In general, dose selection for an elderly patient should be cautious, usually starting at the low end of the dosing range, reflecting the greater frequency of decreased hepatic, renal, or cardiac function, and of concomitant disease or other drug therapy. ADVERSE REACTIONS The safety and efficacy of DITROPAN® (oxybutynin chloride) was evaluated in a total of 199 patients in three clinical trials. These participants were treated with DITROPAN 5-20 mg/day for up to 6 weeks. Table 3 shows the incidence of adverse events judged by investigators to be at least possibly related to treatment and reported by at least 5% of patients. The most common adverse events reported by patients receiving DITROPAN 5-20 mg/day were the expected side effects of anticholinergic agents. The incidence of dry mouth was dose-related. 8 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda In addition, the following adverse events were reported by 1 to <5% of patients using DITROPAN (5-20 mg/day) in all studies. Infections and Infestations: nasopharyngitis, upper respiratory tract infection, bronchitis, cystitis, fungal infection; Metabolism and Nutrition Disorders: fluid retention; Psychiatric Disorders: confusional state; Nervous System Disorders: dysgeusia, sinus headache; Eye Disorders: keratoconjunctivitis sicca, eye irritation; Cardiac Disorders: palpitations, sinus arrhythmia; Vascular Disorders: flushing; Respiratory, Thoracic and Mediastinal Disorders: nasal dryness, cough, pharyngolaryngeal pain, dry throat, sinus congestion, hoarseness, asthma, nasal congestion; Gastrointestinal Disorders: diarrhea, abdominal pain, loose stools, flatulence, vomiting, abdominal pain upper, dysphagia, aptyalism, eructation, tongue coated; Skin and Subcutaneous Tissue Disorders: dry skin, pruritis; Musculoskeletal and Connective Tissue Disorders: back pain, arthralgia, pain in extremity, flank pain; Renal and Urinary Disorders: dysuria, pollakiuria; General Disorders and Administration Site Conditions: fatigue, edema peripheral, asthenia, pain, thirst, edema; Investigations: blood pressure increased, blood glucose increased, blood pressure decreased; Injury, Poisoning, and Procedural Complications: fall. Postmarketing Surveillance Because postmarketing adverse events are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure. The following additional adverse events have been reported from worldwide postmarketing experience with DITROPAN: Psychiatric Disorders: psychotic disorder, agitation, hallucination, memory impairment; Nervous System Disorders: convulsions; Eye Disorders: cycloplegia, mydriasis; Cardiac Disorders: tachycardia, QT interval prolongation; Gastrointestinal Disorders: decreased gastrointestinal motility; Skin and Subcutaneous Tissue Disorders: rash, decreased sweating; Renal and Urinary Disorders: impotence; Reproductive System and Breast Disorders: Suppression of lactation. OVERDOSAGE Treatment should be symptomatic and supportive. Activated charcoal as well as a cathartic may be administered. Overdosage with oxybutynin chloride has been associated with anticholinergic effects including central nervous system excitation (e.g., restlessness, tremor, irritability, convulsions, delirium, hallucinations), flushing, fever, dehydration, cardiac 9 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda arrhythmia, vomiting, and urinary retention. Other symptoms may include hypotension or hypertension, respiratory failure, paralysis, and coma. Ingestion of 100 mg oxybutynin chloride in association with alcohol has been reported in a 13-year-old boy who experienced memory loss, and a 34 year old woman who developed stupor, followed by disorientation and agitation on awakening, dilated pupils, dry skin, cardiac arrhythmia, and retention of urine. Both patients fully recovered with symptomatic treatment. DOSAGE AND ADMINISTRATION Adults: The usual dose is one 5-mg tablet two to three times a day. The maximum recommended dose is one 5-mg tablet four times a day. A lower starting dose of 2.5 mg two or three times a day is recommended for the frail elderly.

NDA 17-577 DITROPAN (oxybutynin chloride) Tablets (Final Draft submitted 4/9/2003) NDA 18-211 DITROPAN (oxybutynin chloride) Syrup (Final Draft submitted 4/9/2003) 1 DITROPAN® (oxybutynin chloride) Tablets and Syrup DESCRIPTION Each scored biconvex, engraved blue DITROPAN (oxybutynin chloride) Tablet contains 5 mg of oxybutynin chloride. Each 5 mL of DITROPAN Syrup contains 5 mg of oxybutynin chloride. Chemically, oxybutynin chloride is d,l (racemic) 4-diethylamino-2- butynyl phenylcyclohexylglycolate hydrochloride. The empirical formula of oxybutynin chloride is C22H31NO3•HCl. The structural formula appears below: Oxybutynin chloride is a white crystalline solid with a molecular weight of 393.9. It is readily soluble in water and acids, but relatively insoluble in alkalis. DITROPAN Tablets Also contains: calcium stearate, FD&C Blue #1 Lake, lactose, and microcrystalline cellulose. DITROPAN Syrup Also contains: citric acid, FD&C Green #3, glycerin, methylparaben, flavor, sodium citrate, sorbitol, sucrose, and water. DITROPAN Tablets and Syrup are for oral administration. Therapeutic Category: Antispasmodic, anticholinergic. CLINICAL PHARMACOLOGY Oxybutynin chloride exerts a direct antispasmodic effect on smooth muscle and inhibits the muscarinic action of acetylcholine on smooth muscle. Oxybutynin chloride exhibits only one fifth of the anticholinergic activity of atropine on the rabbit detrusor muscle, but four to ten times the antispasmodic activity. No blocking effects occur at skeletal neuromuscular junctions or autonomic ganglia (antinicotinic effects). Oxybutynin chloride relaxes bladder smooth muscle. In patients with conditions characterized by involuntary bladder contractions, cystometric studies have demonstrated that oxybutynin chloride increases bladder (vesical) capacity, diminishes the frequency of uninhibited contractions of the detrusor muscle, and delays the initial desire to void. Oxybutynin chloride thus decreases urgency and the frequency of both incontinent episodes and voluntary urination. Antimuscarinic activity resides predominately in the R-isomer. A metabolite, desethyloxybutynin, has pharmacological activity similar to that of oxybutynin in in vitro studies. Pharmacokinetics Absorption Following oral administration of DITROPAN, oxybutynin is rapidly absorbed achieving Cmax within an hour, following which plasma concentration decreases with an effective half-life of approximately 2 to 3 hours. The absolute bioavailability of oxybutynin is This label may not be the latest approved by FDA.

Carcinogenesis, Mutagenesis, Impairment of Fertility A 24-month study in rats at dosages of oxybutynin chloride of 20, 80, and 160 mg/kg/day showed no evidence of carcinogenicity. These doses are approximately 6, 25, and 50 times the maximum human exposure, based on surface area. Oxybutynin chloride showed no increase of mutagenic activity when tested in Schizosaccharomyces pompholiciformis, Saccharomyces cerevisiae and Salmonella typhimurium test systems. Reproduction studies using oxybutynin chloride in the hamster, rabbit, rat, and mouse have shown no definite evidence of impaired fertility. Pregnancy Category B. Reproduction studies using oxybutynin chloride in the hamster, rabbit, rat, and mouse have shown no definite evidence of impaired fertility or harm to the animal fetus. The safety of DITROPAN administered to women who are or who may become pregnant has not been established. Therefore, DITROPAN should not be given to pregnant women unless, in the judgment of the physician, the probable clinical benefits outweigh the possible hazards. Nursing Mothers It is not known whether this drug is excreted in human milk. Because many drugs are excreted in human milk, caution should be exercised when DITROPAN is administered to a nursing woman. This label may not be the latest approved by FDA.

The safety and efficacy of Ditropan Tablets and Ditropan Syrup were studied in 30 and in 26 children, respectively, in a 24-week, open-label trial. Patients were aged 5-15 years, all had symptoms of detrusor overactivity in association with a neurological condition (e.g., spina bifida), all used clean intermittent catheterization, and all were current users of oxybutynin chloride. Study results demonstrated that the administration of DITROPAN was associated with improvement in clinical and urodynamic parameters. At total daily doses ranging from 5 mg to 15 mg, treatment with Ditropan Tablets was associated with an increase from baseline in mean urine volume per catheterization from 122 mL to 145 mL, an increase from baseline in mean urine volume after morning awakening from 148 mL to 168 mL, and an increase from baseline in the mean percentage of catheterizations without a leaking episode from 43% to 61%. Urodynamic results in these patients were consistent with the clinical results. Treatment with Ditropan Tablets was associated with an increase from baseline in maximum cystometric capacity from 230 mL to 279 mL, a decrease from baseline in mean detrusor pressure at maximum cystometric capacity from 36 cm H20 to 33 cm H20, and a reduction in the percentage of patients demonstrating uninhibited detrusor contractions (of at least 15 cm H20) from 39% to 20%. At total daily doses ranging from 5 mg to 30 mg, treatment with Ditropan Syrup was associated with an increase from baseline in mean urine volume per catheterization from 113 mL to 133 mL, an increase from baseline in mean urine volume after morning awakening from 143 mL to 165 mL, and an increase from baseline in the mean percentage of catheterizations without a leaking episode from 34% to 63%. Urodynamic results were consistent with these clinical results. Treatment with Ditropan Syrup was associated with an increase from baseline in maximum cystometric capacity from 192 mL to 294 mL, a decrease from baseline in mean detrusor pressure at maximum cystometric capacity from 46 cm H20 to 37 cm H20, and a reduction in the percentage of patients demonstrating uninhibited detrusor contractions (of at least 15 cm H20) from 67% to 28%. As there is insufficient clinical data for pediatric populations under age 5, DITROPAN is not recommended for this age group. Geriatric Use Clinical studies of DITROPAN did not include sufficient numbers of subjects age 65 and over to determine whether they respond differently from younger patients. Other reported clinical experience has not identified differences in responses between healthy elderly and younger patients; however, a lower initial starting dose of 2.5 mg given 2 or 3 times a day has been recommended for the frail elderly due to a prolongation of the This label may not be the latest approved by FDA.

OVERDOSAGE Treatment should be symptomatic and supportive. Activated charcoal as well as a cathartic may be administered. Overdosage with oxybutynin chloride has been associated with anticholinergic effects including central nervous system excitation (e.g., restlessness, tremor, irritability, convulsions, delirium, hallucinations), flushing, fever, dehydration, cardiac arrhythmia, vomiting, and urinary retention. Other symptoms may include hypotension or hypertension, respiratory failure, paralysis, and coma. Ingestion of 100 mg oxybutynin chloride in association with alcohol has been reported in a 13 year old boy who experienced memory loss, and a 34 year old woman who developed stupor, followed by disorientation and agitation on awakening, dilated pupils, dry skin, cardiac arrhythmia, and retention of urine. Both patients fully recovered with symptomatic treatment. DOSAGE AND ADMINISTRATION Tablets Adults: The usual dose is one 5-mg tablet two to three times a day.

Each DITROPAN XL Extended Release Tablet contains 5 mg, 10 mg or 15 mg of oxybutynin chloride USP, formulated as a once-a-day controlled-release tablet for oral administration. Oxybutynin chloride is administered as a racemate of R- and S- enantiomers. Chemically, oxybutynin chloride is d,l (racemic) 4-diethylamino-2-butynyl phenylcyclohexylglycolate hydrochloride. The empirical formula of oxybutynin chloride is C22H31NO3 • HCl. Its structural formula is: Oxybutynin chloride is a white crystalline solid with a molecular weight of 393.9. It is readily soluble in water and acids, but relatively insoluble in alkalis. DITROPAN XL also contains the following inert ingredients: cellulose acetate, hydroxypropyl methylcellulose, lactose, magnesium stearate, polyethylene glycol, polyethylene oxide, synthetic iron oxides, titanium dioxide, polysorbate 80, sodium chloride, and butylated hydroxytoluene. System Components and Performance DITROPAN XL uses osmotic pressure to deliver oxybutynin chloride at a controlled rate over approximately 24 hours. The system, which resembles a conventional tablet in appearance, comprises an osmotically active bilayer core surrounded by a semipermeable membrane. The bilayer core is composed of a drug layer containing the drug and excipients, and a push layer containing osmotically active components. There is a precision-laser drilled orifice in the semipermeable membrane on the drug-layer side of the tablet. In an aqueous environment, such as the gastrointestinal tract, water permeates through the membrane into the tablet core, causing the drug to go into suspension and the push layer to expand. This expansion pushes the suspended drug out through the orifice. The semipermeable membrane controls the rate at which water permeates into the tablet core, which in turn controls the rate of drug delivery. The controlled rate of drug delivery into the gastrointestinal lumen is thus independent of pH or gastrointestinal motility. The function of DITROPAN XL depends on the existence of an osmotic gradient between the contents of the bilayer core and the fluid in the gastrointestinal tract. Since the osmotic gradient remains constant, drug delivery remains essentially constant. The biologically inert components of the tablet remain intact during gastrointestinal transit and are eliminated in the feces as an insoluble shell. This label may not be the latest approved by FDA.

Oxybutynin chloride exhibits only one-fifth of the anticholinergic activity of atropine on the rabbit detrusor muscle, but four to ten times the antispasmodic activity. No blocking effects occur at skeletal neuromuscular junctions or autonomic ganglia (antinicotinic effects). Oxybutynin chloride relaxes bladder smooth muscle. In patients with conditions characterized by involuntary bladder contractions, cystometric studies have demonstrated that oxybutynin increases bladder (vesical) capacity, diminishes the frequency of uninhibited contractions of the detrusor muscle, and delays the initial desire to void. Oxybutynin thus decreases urgency and the frequency of both incontinent episodes and voluntary urination. Antimuscarinic activity resides predominantly in the R-isomer. A metabolite, desethyloxybutynin, has pharmacological activity similar to that of oxybutynin in in vitro studies. Pharmacokinetics Absorption Following the first dose of DITROPAN XL® (oxybutynin chloride), oxybutynin plasma concentrations rise for 4 to 6 hours; thereafter steady concentrations are maintained for up to 24 hours, minimizing fluctuations between peak and trough concentrations associated with oxybutynin. The relative bioavailabilities of R- and S-oxybutynin from DITROPAN XL are 156% and 187%, respectively, compared with oxybutynin. The mean pharmacokinetic parameters for R- and S- oxybutynin are summarized in Table 1. The plasma concentration-time profiles for R- and S- oxybutynin are similar in shape; Figure 1 shows the profile for R-oxybutynin.

Mean R-oxybutynin plasma concentrations following a single dose of DITROPAN XL 10 mg and oxybutynin 5 mg administered every 8 hours (n=23 for each treatment). Steady-state oxybutynin plasma concentrations are achieved by Day 3 of repeated DITROPAN XL® (oxybutynin chloride) dosing, with no observed drug accumulation or change in oxybutynin and desethyloxybutynin pharmacokinetic parameters. DITROPAN XL steady-state pharmacokinetics was studied in 19 children aged 5-15 years with detrusor overactivity associated with a neurological condition (e.g. spina bifida). The children were on DITROPAN XL total daily dose ranging from 5 to 20 mg (0.10 to 0.77 mg/kg). Sparse sampling technique was used to obtain serum samples. When all available data are normalized to an equivalent of 5mg per day Ditropan XL, the mean pharmacokinetic parameters derived for R- and S-oxybutynin and R- and S-desethyloxybutynin are summarized in Table 2. The plasma- time concentration profiles for R- and S-oxybutynin are similar in shape; Figure 2 shows the profile for R-oxybutynin when all available data are normalized to an equivalent of 5 mg per day.

Distribution Plasma concentrations of oxybutynin decline biexponentially following intravenous or oral administration. The volume of distribution is 193 L after intravenous administration of 5 mg oxybutynin chloride. Metabolism Oxybutynin is metabolized primarily by the cytochrome P450 enzyme systems, particularly CYP3A4 found mostly in the liver and gut wall. Its metabolic products include phenylcyclohexylglycolic acid, which is pharmacologically inactive, and desethyloxybutynin, which is pharmacologically active. Following DITROPAN XL administration, plasma concentrations of R- and S-desethyloxybutynin are 73% and 92%, respectively, of concentrations observed with oxybutynin. Excretion Oxybutynin is extensively metabolized by the liver, with less than 0.1% of the administered dose excreted unchanged in the urine. Also, less than 0.1% of the administered dose is excreted as the metabolite desethyloxybutynin.

Pediatric: The pharmacokinetics of DITROPAN XL (oxybutynin chloride) were evaluated in 19 children aged 5-15 years with detrusor overactivity associated with a neurological condition (e.g., spina bifida). The pharmacokinetics of DITROPAN XL in these pediatric patients were consistent with those reported for adults (see Tables 1 and 2, and Figures 1 and 2 above). Gender: There are no significant differences in the pharmacokinetics of oxybutynin in healthy male and female volunteers following administration of DITROPAN XL. Race: Available data suggest that there are no significant differences in the pharmacokinetics of oxybutynin based on race in healthy volunteers following administration of DITROPAN XL. Renal Insufficiency: There is no experience with the use of DITROPAN XL in patients with renal insufficiency. Hepatic Insufficiency: There is no experience with the use of DITROPAN XL in patients with hepatic insufficiency. Drug-Drug Interactions: See PRECAUTIONS: Drug Interactions. Clinical Studies DITROPAN XL was evaluated for the treatment of patients with overactive bladder with symptoms of urge urinary incontinence, urgency, and frequency in three controlled studies and one open label study. The majority of patients were Caucasian (89.0%) and female (91.9%) with a mean age of 59 years (range, 18 to 98 years). Entry criteria required that patients have urge or mixed incontinence (with a predominance of urge) as evidenced by ≥ 6 urge incontinence episodes per week and ≥ 10 micturitions per day. Study 1 was a forced dose escalation design, whereas the other studies used a dose adjustment design in which each patient’s final dose was adjusted to a balance between improvement of incontinence symptoms and tolerability of side effects. Controlled studies included patients known to be responsive to oxybutynin or other anticholinergic medications, and these patients were maintained on a final dose for up to 2 weeks. The efficacy results for the three controlled trials are presented in the following tables and figures. This label may not be the latest approved by FDA.

DITROPAN XL is also indicated in the treatment of pediatric patients aged 6 years and older with symptoms of detrusor overactivity associated with a neurological condition (e.g., spina bifida). CONTRAINDICATIONS DITROPAN XL is contraindicated in patients with urinary retention, gastric retention and other severe decreased gastrointestinal motility conditions, uncontrolled narrow-angle glaucoma and in patients who are at risk for these conditions. DITROPAN XL is also contraindicated in patients who have demonstrated hypersensitivity to the drug substance or other components of the product. PRECAUTIONS General DITROPAN XL should be used with caution in patients with hepatic or renal impairment and in patients with myasthenia gravis due to the risk of symptom aggravation. Urinary Retention: DITROPAN XL should be administered with caution to patients with clinically significant bladder outflow obstruction because of the risk of urinary retention (see CONTRAINDICATIONS). Gastrointestinal Disorders: DITROPAN XL should be administered with caution to patients with gastrointestinal obstructive disorders because of the risk of gastric retention (see CONTRAINDICATIONS). DITROPAN XL, like other anticholinergic drugs, may decrease gastrointestinal motility and should be used with caution in patients with conditions such as ulcerative colitis and intestinal atony. DITROPAN XL should be used with caution in patients who have gastroesophageal reflux and/or who are concurrently taking drugs (such as bisphosphonates) that can cause or exacerbate esophagitis. As with any other nondeformable material, caution should be used when administering DITROPAN XL to patients with preexisting severe gastrointestinal narrowing (pathologic or iatrogenic). There have been rare reports of obstructive symptoms in patients with known strictures in association with the ingestion of other drugs in nondeformable controlled-release formulations. Information for Patients Patients should be informed that heat prostration (fever and heat stroke due to decreased sweating) can occur when anticholinergics such as oxybutynin chloride are administered in the presence of high environmental temperature. This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda NDA 20-897: DITROPAN XL® (oxybutynin chloride) Extended Release Tablets – Revised Final Draft (Submitted April 3, 2003) 8 Because anticholinergic agents such as oxybutynin may produce drowsiness (somnolence) or blurred vision, patients should be advised to exercise caution. Patients should be informed that alcohol may enhance the drowsiness caused by anticholinergic agents such as oxybutynin. Patients should be informed that DITROPAN XL® (oxybutynin chloride) should be swallowed whole with the aid of liquids. Patients should not chew, divide, or crush tablets. The medication is contained within a nonabsorbable shell designed to release the drug at a controlled rate. The tablet shell is eliminated from the body; patients should not be concerned if they occasionally notice in their stool something that looks like a tablet. Drug Interactions The concomitant use of oxybutynin with other anticholinergic drugs or with other agents which produce dry mouth, constipation, somnolence (drowsiness), and/or other anticholinergic-like effects may increase the frequency and/or severity of such effects. Anticholinergic agents may potentially alter the absorption of some concomitantly administered drugs due to anticholinergic effects on gastrointestinal motility. This may be of concern for drugs with a narrow therapeutic index. Mean oxybutynin chloride plasma concentrations were approximately 2 fold higher when DITROPAN XL was administered with ketoconazole, a potent CYP3A4 inhibitor. Other inhibitors of the cytochrome P450 3A4 enzyme system, such as antimycotic agents (e.g., itraconazole and miconazole) or macrolide antibiotics (e.g., erythromycin and clarithromycin), may alter oxybutynin mean pharmacokinetic parameters (i.e., Cmax and AUC). The clinical relevance of such potential interactions is not known. Caution should be used when such drugs are co- administered. Carcinogenesis, Mutagenesis, Impairment of Fertility A 24-month study in rats at dosages of oxybutynin chloride of 20, 80 and 160 mg/kg/day showed no evidence of carcinogenicity. These doses are approximately 6, 25 and 50 times the maximum human exposure, based on surface area. Oxybutynin chloride showed no increase of mutagenic activity when tested in Schizosaccharomyces pompholiciformis, Saccharomyces cerevisiae, and Salmonella typhimurium test systems. Reproduction studies with oxybutynin chloride in the mouse, rat, hamster, and rabbit showed no definite evidence of impaired fertility. Pregnancy: Teratogenic Effects Pregnancy Category B Reproduction studies with oxybutynin chloride in the mouse, rat, hamster, and rabbit showed no definite evidence of impaired fertility or harm to the animal fetus. The safety of DITROPAN XL administration to women who are or who may become pregnant has not been established. Therefore, DITROPAN XL should not be given to pregnant women unless, in the judgment of the physician, the probable clinical benefits outweigh the possible hazards.

Because many drugs are excreted in human milk, caution should be exercised when DITROPAN XL® (oxybutynin chloride) is administered to a nursing woman. Pediatric Use The safety and efficacy of DITROPAN XL were studied in 60 children in a 24-week, open-label trial. Patients were aged 6-15 years, all had symptoms of detrusor overactivity in association with a neurological condition (e.g., spina bifida), all used clean intermittent catheterization, and all were current users of oxybutynin chloride. Study results demonstrated that administration of DITROPAN XL 5 to 20 mg/day was associated with an increase from baseline in mean urine volume per catheterization from 108 mL to 136 mL, an increase from baseline in mean urine volume after morning awakening from 148 mL to 189 mL, and an increase from baseline in the mean percentage of catheterizations without a leaking episode from 34% to 51%. Urodynamic results were consistent with clinical results. Administration of DITROPAN XL resulted in an increase from baseline in mean maximum cystometric capacity from 185 mL to 254 mL, a decrease from baseline in mean detrusor pressure at maximum cystometric capacity from 44 cm H2O to 33 cm H2O, and a reduction in the percentage of patients demonstrating uninhibited detrusor contractions (of at least 15 cm H2O) from 60% to 28%. DITROPAN XL is not recommended in pediatric patients who can not swallow the tablet whole without chewing, dividing, or crushing, or in children under the age of 6 (see DOSAGE AND ADMINISTRATION). Geriatric Use The rate and severity of anticholinergic effects reported by patients less than 65 years old and those 65 years and older were similar (See CLINICAL PHARMACOLOGY, Pharmacokinetics, Special Populations: Gender). ADVERSE REACTIONS Adverse Events with DITROPAN XL® The safety and efficacy of DITROPAN XL was evaluated in a total of 580 participants who received DITROPAN XL in clinical trials (429 patients, 151 healthy volunteers). These participants were treated with 5-30 mg/day for up to 4.5 months. Safety information is provided for 429 patients from three controlled clinical studies and one open label study (Table 3). The adverse events are reported regardless of causality. This label may not be the latest approved by FDA.

The incidence of dry mouth was dose-related. The discontinuation rate for all adverse events was 6.8%. The most frequent adverse event causing early discontinuation of study medication was nausea (1.9%), while discontinuation due to dry mouth was 1.2%. In addition, the following adverse events were reported by 2 to < 5% of patients using DITROPAN XL (oxybutynin chloride) (5-30 mg/day) in all studies. General: abdominal pain, dry nasal and sinus mucous membranes, accidental injury, back pain, flu syndrome; Cardiovascular: hypertension, palpitation, vasodilatation; Digestive: flatulence, gastroesophageal reflux; Musculoskeletal: arthritis; Nervous: insomnia, nervousness, confusion; Respiratory: upper respiratory tract infection, cough, sinusitis, bronchitis, pharyngitis; Skin: dry skin, rash; Urogenital: impaired urination (hesitancy), increased post void residual volume, urinary retention, cystitis. Additional rare adverse events reported from worldwide post-marketing experience with DITROPAN XL include: peripheral edema, cardiac arrhythmia, tachycardia, hallucinations, convulsions, and impotence. Additional adverse events reported with some other oxybutynin chloride formulations include: cycloplegia, mydriasis, and suppression of lactation. OVERDOSAGE The continuous release of oxybutynin from DITROPAN XL (oxybutynin chloride) should be considered in the treatment of overdosage. Patients should be monitored for at least 24 hours. Treatment should be symptomatic and supportive. Activated charcoal as well as a cathartic may be administered. Overdosage with oxybutynin chloride has been associated with anticholinergic effects including central nervous system excitation, flushing, fever, dehydration, cardiac arrhythmia, vomiting, and urinary retention.

1 DITROPAN® (oxybutynin chloride) Tablets and Syrup DESCRIPTION Each scored biconvex, engraved blue DITROPAN® (oxybutynin chloride) Tablet contains 5 mg of oxybutynin chloride. Each 5 mL of DITROPAN Syrup contains 5 mg of oxybutynin chloride. Chemically, oxybutynin chloride is d,l (racemic) 4-diethylamino-2-butynyl phenylcyclohexylglycolate hydrochloride. The empirical formula of oxybutynin chloride is C22H31NO3•HCl. The structural formula appears below: Oxybutynin chloride is a white crystalline solid with a molecular weight of 393.9. It is readily soluble in water and acids, but relatively insoluble in alkalis. DITROPAN Tablets also contain calcium stearate, FD&C Blue #1 Lake, lactose, and microcrystalline cellulose. DITROPAN Syrup also contains citric acid, FD&C Green #3, glycerin, methylparaben, flavor, sodium citrate, sorbitol, sucrose, and water. DITROPAN Tablets and Syrup are for oral administration. Therapeutic Category: Antispasmodic, anticholinergic. CLINICAL PHARMACOLOGY Oxybutynin chloride exerts a direct antispasmodic effect on smooth muscle and inhibits the muscarinic action of acetylcholine on smooth muscle. Oxybutynin chloride exhibits only one fifth of the anticholinergic activity of atropine on the rabbit detrusor muscle, but four to ten times the antispasmodic activity. No blocking effects occur at skeletal neuromuscular junctions or autonomic ganglia (antinicotinic effects). Oxybutynin chloride relaxes bladder smooth muscle. In patients with conditions characterized by involuntary bladder contractions, cystometric studies have demonstrated that oxybutynin chloride increases bladder (vesical) capacity, diminishes the frequency of uninhibited contractions of the detrusor muscle, and delays the initial desire to void. Oxybutynin chloride thus decreases urgency and the frequency of both incontinent episodes and voluntary urination. This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda 2 Antimuscarinic activity resides predominately in the R-isomer. A metabolite, desethyloxybutynin, has pharmacological activity similar to that of oxybutynin in in vitro studies. Pharmacokinetics Absorption Following oral administration of DITROPAN, oxybutynin is rapidly absorbed achieving Cmax within an hour, following which plasma concentration decreases with an effective half-life of approximately 2 to 3 hours. The absolute bioavailability of oxybutynin is reported to be about 6% (range 1.6 to 10.9%) for both the tablet and syrup. Wide interindividual variation in pharmacokinetic parameters is evident following oral administration of oxybutynin. The mean pharmacokinetic parameters for R- and S-oxybutynin are summarized in Table 1. The plasma concentration-time profiles for R- and S-oxybutynin are similar in shape; Figure 1 shows the profile for R-oxybutynin. Table 1 Mean (SD) R- and S-Oxybutynin Pharmacokinetic Parameters Following Three Doses of DITROPAN 5 mg Administered every 8 Hours (n=23) Parameters (units) R-Oxybutynin S-Oxybutynin Cmax (ng/mL) 3.6 (2.2) 7.8 (4.1) Tmax (h) 0.89 (0.34) 0.65 (0.32) AUCt (ng⋅h/mL) 22.6 (11.3) 35.0 (17.3) AUCinf (ng⋅h/mL) 24.3 (12.3) 37.3 (18.7) 0 0.5 1 1.5 2 2.5 3 3.5 4 4.5 5 0 4 8 12 16 20 24 Time (h) Mean Plasma R-Oxybutynin Concentration (ng/mL) Oxybutynin 5 mg TID Figure 1.

These pediatric patients were on DITROPAN tablets (n=11) with total daily dose ranging from 7.5 mg to 15 mg (0.22 to 0.53 mg/kg) or DITROPAN syrup (n=12) with total daily dose ranging from 5 mg to 22.5 mg (0.26 to 0.75 mg/kg). Overall, most patients (86.9%) were taking a total daily DITROPAN dose between 10 mg and 15 mg. Sparse sampling technique was used to obtain serum samples. When all available data are normalized to an equivalent of 5 mg twice daily DITROPAN, the mean pharmacokinetic parameters derived for R- and S-oxybutynin and R- and S-desethyloxybutynin are summarized in Table 2a (for tablet) and Table 2b (for syrup). The plasma-time concentration profiles for R- and S-oxybutynin are similar in shape; Figure 2 shows the profile for R-oxybutynin when all available data are normalized to an equivalent of 5 mg twice daily.

The volume of distribution is 193 L after intravenous administration of 5 mg oxybutynin chloride. Metabolism Oxybutynin is metabolized primarily by the cytochrome P450 enzyme systems, particularly CYP3A4 found mostly in the liver and gut wall. Its metabolic products include phenylcyclohexylglycolic acid, which is pharmacologically inactive, and desethyloxybutynin, which is pharmacologically active. Excretion Oxybutynin is extensively metabolized by the liver, with less than 0.1% of the administered dose excreted unchanged in the urine. Also, less than 0.1% of the administered dose is excreted as the metabolite desethyloxybutynin. This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda 5 CLINICAL STUDIES DITROPAN was well tolerated in patients administered the drug in controlled studies of 30 days’ duration and in uncontrolled studies in which some of the patients received the drug for 2 years. INDICATIONS AND USAGE DITROPAN® (oxybutynin chloride) is indicated for the relief of symptoms of bladder instability associated with voiding in patients with uninhibited neurogenic or reflex neurogenic bladder (i.e., urgency, frequency, urinary leakage, urge incontinence, dysuria). CONTRAINDICATIONS DITROPAN® (oxybutynin chloride) is contraindicated in patients with urinary retention, gastric retention and other severe decreased gastrointestinal motility conditions, uncontrolled narrow-angle glaucoma and in patients who are at risk for these conditions. DITROPAN is also contraindicated in patients who have demonstrated hypersensitivity to the drug substance or other components of the product. PRECAUTIONS Central Nervous System Effects Oxybutynin is associated with anticholinergic central nervous system (CNS) effects (See ADVERSE REACTIONS). A variety of CNS anticholinergic effects have been reported, including hallucinations, agitation, confusion and somnolence. Patients should be monitored for signs of anticholinergic CNS effects, particularly in the first few months after beginning treatment or increasing the dose. If a patient experiences anticholinergic CNS effects, dose reduction or drug discontinuation should be considered. DITROPAN should be used with caution in patients with preexisting dementia treated with cholinesterase inhibitors due to the risk of aggravation of symptoms. General DITROPAN® (oxybutynin chloride) should be used with caution in the frail elderly, in patients with hepatic or renal impairment, and in patients with myasthenia gravis. DITROPAN may aggravate the symptoms of hyperthyroidism, coronary heart disease, congestive heart failure, cardiac arrhythmias, hiatal hernia, tachycardia, hypertension, myasthenia gravis, and prostatic hypertrophy. This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda 6 Urinary Retention DITROPAN should be administered with caution to patients with clinically significant bladder outflow obstruction because of the risk of urinary retention (see CONTRAINDICATIONS). Gastrointestinal Disorders DITROPAN should be administered with caution to patients with gastrointestinal obstructive disorders because of the risk of gastric retention (see CONTRAINDICATIONS). Administration of DITROPAN to patients with ulcerative colitis may suppress intestinal motility to the point of producing a paralytic ileus and precipitate or aggravate toxic megacolon, a serious complication of the disease. DITROPAN, like other anticholinergic drugs, may decrease gastrointestinal motility and should be used with caution in patients with conditions such as ulcerative colitis, and intestinal atony. DITROPAN should be used with caution in patients who have gastroesophageal reflux and/or who are concurrently taking drugs (such as bisphosphonates) that can cause or exacerbate esophagitis. Information for Patients Patients should be informed that heat prostration (fever and heat stroke due to decreased sweating) can occur when anticholinergics such as oxybutynin chloride are administered in the presence of high environmental temperature. Because anticholinergic agents such as oxybutynin may produce drowsiness (somnolence), or blurred vision, patients should be advised to exercise caution. Patients should be informed that alcohol may enhance the drowsiness caused by anticholinergic agents such as oxybutynin. Drug Interactions The concomitant use of oxybutynin with other anticholinergic drugs or with other agents which produce dry mouth, constipation, somnolence (drowsiness), and/or other anticholinergic-like effects may increase the frequency and/or severity of such effects. Anticholinergic agents may potentially alter the absorption of some concomitantly administered drugs due to anticholinergic effects on gastrointestinal motility. This may be of concern for drugs with a narrow therapeutic index. This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda 7 Mean oxybutynin chloride plasma concentrations were approximately 3-4 fold higher when DITROPAN was administered with ketoconazole, a potent CYP3A4 inhibitor. Other inhibitors of the cytochrome P450 3A4 enzyme system, such as antimycotic agents (e.g., itraconazole and miconazole) or macrolide antibiotics (e.g., erythromycin and clarithromycin), may alter oxybutynin mean pharmacokinetic parameters (i.e., Cmax and AUC). The clinical relevance of such potential interactions is not known. Caution should be used when such drugs are co-administered. Carcinogenesis, Mutagenesis, Impairment of Fertility A 24-month study in rats at dosages of oxybutynin chloride of 20, 80, and 160 mg/kg/day showed no evidence of carcinogenicity. These doses are approximately 6, 25, and 50 times the maximum human exposure, based on surface area. Oxybutynin chloride showed no increase of mutagenic activity when tested in Schizosaccharomyces pompholiciformis, Saccharomyces cerevisiae and Salmonella typhimurium test systems. Reproduction studies using oxybutynin chloride in the hamster, rabbit, rat, and mouse have shown no definite evidence of impaired fertility. Pregnancy Category B. Reproduction studies using oxybutynin chloride in the hamster, rabbit, rat, and mouse have shown no definite evidence of impaired fertility or harm to the animal fetus. The safety of DITROPAN administered to women who are or who may become pregnant has not been established. Therefore, DITROPAN should not be given to pregnant women unless, in the judgment of the physician, the probable clinical benefits outweigh the possible hazards. Nursing Mothers It is not known whether this drug is excreted in human milk. Because many drugs are excreted in human milk, caution should be exercised when DITROPAN is administered to a nursing woman. Pediatric Use The safety and efficacy of DITROPAN administration have been demonstrated for pediatric patients 5 years of age and older (see DOSAGE AND ADMINISTRATION). This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda 8 The safety and efficacy of DITROPAN Tablets and DITROPAN Syrup were studied in 30 and in 26 children, respectively, in a 24-week, open-label trial. Patients were aged 5-15 years, all had symptoms of detrusor overactivity in association with a neurological condition (e.g., spina bifida), all used clean intermittent catheterization, and all were current users of oxybutynin chloride. Study results demonstrated that the administration of DITROPAN was associated with improvement in clinical and urodynamic parameters. At total daily doses ranging from 5 mg to 15 mg, treatment with DITROPAN Tablets was associated with an increase from baseline in mean urine volume per catheterization from 122 mL to 145 mL, an increase from baseline in mean urine volume after morning awakening from 148 mL to 168 mL, and an increase from baseline in the mean percentage of catheterizations without a leaking episode from 43% to 61%. Urodynamic results in these patients were consistent with the clinical results. Treatment with DITROPAN Tablets was associated with an increase from baseline in maximum cystometric capacity from 230 mL to 279 mL, a decrease from baseline in mean detrusor pressure at maximum cystometric capacity from 36 cm H20 to 33 cm H20, and a reduction in the percentage of patients demonstrating uninhibited detrusor contractions (of at least 15 cm H20) from 39% to 20%. At total daily doses ranging from 5 mg to 30 mg, treatment with DITROPAN Syrup was associated with an increase from baseline in mean urine volume per catheterization from 113 mL to 133 mL, an increase from baseline in mean urine volume after morning awakening from 143 mL to 165 mL, and an increase from baseline in the mean percentage of catheterizations without a leaking episode from 34% to 63%. Urodynamic results were consistent with these clinical results. Treatment with DITROPAN Syrup was associated with an increase from baseline in maximum cystometric capacity from 192 mL to 294 mL, a decrease from baseline in mean detrusor pressure at maximum cystometric capacity from 46 cm H20 to 37 cm H20, and a reduction in the percentage of patients demonstrating uninhibited detrusor contractions (of at least 15 cm H20) from 67% to 28%. As there is insufficient clinical data for pediatric populations under age 5, DITROPAN is not recommended for this age group. Geriatric Use Clinical studies of DITROPAN did not include sufficient numbers of subjects age 65 and over to determine whether they respond differently from younger patients. Other reported clinical experience has not identified differences in responses between healthy elderly and younger patients; however, a lower initial starting dose of 2.5 mg This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda 9 given 2 or 3 times a day has been recommended for the frail elderly due to a prolongation of the elimination half-life from 2-3 hours to 5 hours.2, 3, 4 In general, dose selection for an elderly patient should be cautious, usually starting at the low end of the dosing range, reflecting the greater frequency of decreased hepatic, renal, or cardiac function, and of concomitant disease or other drug therapy. ADVERSE REACTIONS The safety and efficacy of DITROPAN® (oxybutynin chloride) was evaluated in a total of 199 patients in three clinical trials comparing DITROPAN with DITROPAN XL (see Table 3). These participants were treated with DITROPAN 5-20 mg/day for up to 6 weeks. Table 3 shows the incidence of adverse events judged by investigators to be at least possibly related to treatment and reported by at least 5% of patients. Table 3 Incidence (%) of Adverse Events Reported by ≥ 5% of Patients Using DITROPAN (5-20 mg/day) Body System Adverse Event DITROPAN (5-20 mg/day) (n=199) Infections and Infestations Urinary tract infection 6.5% Psychiatric Disorders Insomnia Nervousness 5.5% 6.5% Nervous System Disorders Dizziness Somnolence Headache 16.6% 14.0% 7.5% Eye Disorders Blurred vision 9.6% Gastrointestinal Disorders Dry mouth Constipation Nausea Dyspepsia 71.4% 15.1% 11.6% 6.0% Renal and Urinary Disorders Urinary Hesitation Urinary Retention 8.5% 6.0% The most common adverse events reported by patients receiving DITROPAN 5-20 mg/day were the expected side effects of anticholinergic agents. The incidence of dry mouth was dose-related. In addition, the following adverse events were reported by 1 to <5% of patients using DITROPAN (5-20 mg/day) in all studies. Infections and Infestations: nasopharyngitis, upper respiratory tract infection, bronchitis, cystitis, fungal infection; Metabolism and Nutrition Disorders: fluid retention; Psychiatric Disorders: confusional state; Nervous System Disorders: dysgeusia, sinus headache; Eye Disorders: keratoconjunctivitis sicca, eye irritation; Cardiac Disorders: palpitations, sinus arrhythmia; Vascular Disorders: flushing; Respiratory, Thoracic and Mediastinal Disorders: nasal dryness, cough, pharyngolaryngeal pain, dry throat, sinus congestion, hoarseness, asthma, nasal congestion; Gastrointestinal Disorders: This label may not be the latest approved by FDA.

Postmarketing Surveillance Because postmarketing adverse events are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure. The following additional adverse events have been reported from worldwide postmarketing experience with DITROPAN: Psychiatric Disorders: psychotic disorder, agitation, hallucinations; Nervous System Disorders: convulsions; Eye disorders: cycloplegia, mydriasis; Cardiac Disorders: tachycardia; Gastrointestinal Disorders: decreased gastrointestinal motility; Skin and Subcutaneous Tissue Disorders: rash, decreased sweating; Renal and Urinary Disorders: impotence; Reproductive system and breast disorders: Suppression of lactation. OVERDOSAGE Treatment should be symptomatic and supportive. Activated charcoal as well as a cathartic may be administered. Overdosage with oxybutynin chloride has been associated with anticholinergic effects including central nervous system excitation (e.g., restlessness, tremor, irritability, convulsions, delirium, hallucinations), flushing, fever, dehydration, cardiac arrhythmia, vomiting, and urinary retention. Other symptoms may include hypotension or hypertension, respiratory failure, paralysis, and coma. Ingestion of 100 mg oxybutynin chloride in association with alcohol has been reported in a 13-year-old boy who experienced memory loss, and a 34 year old woman who developed stupor, followed by disorientation and agitation on awakening, dilated pupils, dry skin, cardiac arrhythmia, and retention of urine. Both patients fully recovered with symptomatic treatment. This label may not be the latest approved by FDA.

Each DITROPAN XL Extended Release Tablet contains 5 mg, 10 mg, or 15 mg of oxybutynin chloride USP, formulated as a once-a-day controlled-release tablet for oral administration. Oxybutynin chloride is administered as a racemate of R- and S-enantiomers. Chemically, oxybutynin chloride is d,l (racemic) 4-diethylamino-2-butynyl phenylcyclohexylglycolate hydrochloride. The empirical formula of oxybutynin chloride is C22H31NO3 • HCl. Its structural formula is: Oxybutynin chloride is a white crystalline solid with a molecular weight of 393.9. It is readily soluble in water and acids, but relatively insoluble in alkalis. DITROPAN XL also contains the following inert ingredients: cellulose acetate, hypromellose, lactose, magnesium stearate, polyethylene glycol, polyethylene oxide, synthetic iron oxides, titanium dioxide, polysorbate 80, sodium chloride, and butylated hydroxytoluene. System Components and Performance DITROPAN XL uses osmotic pressure to deliver oxybutynin chloride at a controlled rate over approximately 24 hours. The system, which resembles a conventional tablet in appearance, comprises an osmotically active bilayer core surrounded by a semipermeable membrane. The bilayer core is composed of a drug layer containing the drug and excipients, and a push layer containing osmotically active components. There is a precision-laser drilled orifice in the semipermeable membrane on the drug-layer side of the tablet. In an aqueous environment, such as the gastrointestinal tract, water permeates through the membrane into the tablet core, causing the drug to go into suspension and the push layer to expand. This expansion pushes the suspended drug out through the orifice. The semipermeable membrane controls the This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda 2 rate at which water permeates into the tablet core, which in turn controls the rate of drug delivery. The controlled rate of drug delivery into the gastrointestinal lumen is thus independent of pH or gastrointestinal motility. The function of DITROPAN XL depends on the existence of an osmotic gradient between the contents of the bilayer core and the fluid in the gastrointestinal tract. Since the osmotic gradient remains constant, drug delivery remains essentially constant. The biologically inert components of the tablet remain intact during gastrointestinal transit and are eliminated in the feces as an insoluble shell. CLINICAL PHARMACOLOGY Oxybutynin chloride exerts a direct antispasmodic effect on smooth muscle and inhibits the muscarinic action of acetylcholine on smooth muscle. Oxybutynin chloride exhibits only one-fifth of the anticholinergic activity of atropine on the rabbit detrusor muscle, but four to ten times the antispasmodic activity. No blocking effects occur at skeletal neuromuscular junctions or autonomic ganglia (antinicotinic effects). Oxybutynin chloride relaxes bladder smooth muscle. In patients with conditions characterized by involuntary bladder contractions, cystometric studies have demonstrated that oxybutynin increases bladder (vesical) capacity, diminishes the frequency of uninhibited contractions of the detrusor muscle, and delays the initial desire to void. Oxybutynin thus decreases urgency and the frequency of both incontinent episodes and voluntary urination. Antimuscarinic activity resides predominantly in the R-isomer. A metabolite, desethyloxybutynin, has pharmacological activity similar to that of oxybutynin in in vitro studies. Pharmacokinetics Absorption Following the first dose of DITROPAN XL® (oxybutynin chloride), oxybutynin plasma concentrations rise for 4 to 6 hours; thereafter steady concentrations are maintained for up to 24 hours, minimizing fluctuations between peak and trough concentrations associated with oxybutynin. The relative bioavailabilities of R- and S-oxybutynin from DITROPAN XL are 156% and 187%, respectively, compared with oxybutynin. The mean pharmacokinetic parameters for R- and S-oxybutynin are summarized in Table 1. The plasma concentration-time profiles for R- and S-oxybutynin are similar in shape; Figure 1 shows the profile for R-oxybutynin. This label may not be the latest approved by FDA.

Steady-state oxybutynin plasma concentrations are achieved by Day 3 of repeated DITROPAN XL dosing, with no observed drug accumulation or change in oxybutynin and desethyloxybutynin pharmacokinetic parameters. DITROPAN XL steady-state pharmacokinetics were studied in 19 children aged 5-15 years with detrusor overactivity associated with a neurological condition (e.g. spina bifida). The children were on DITROPAN XL total daily dose ranging from 5 to 20 mg (0.10 to 0.77 mg/kg). Sparse sampling technique was used to obtain serum samples. When all available data are normalized to an equivalent of 5 mg per day DITROPAN XL, the mean pharmacokinetic parameters derived for R- and S-oxybutynin and R- and S-desethyloxybutynin are summarized in Table 2. The plasma-time concentration profiles for R- and S-oxybutynin are similar in shape; Figure 2 shows the profile for R-oxybutynin when all available data are normalized to an equivalent of 5 mg per day.

Food Effects The rate and extent of absorption and metabolism of oxybutynin are similar under fed and fasted conditions. Distribution Plasma concentrations of oxybutynin decline biexponentially following intravenous or oral administration. The volume of distribution is 193 L after intravenous administration of 5 mg oxybutynin chloride. Metabolism Oxybutynin is metabolized primarily by the cytochrome P450 enzyme systems, particularly CYP3A4 found mostly in the liver and gut wall. Its metabolic products include phenylcyclohexylglycolic acid, which is pharmacologically inactive, and desethyloxybutynin, which is pharmacologically active. Following DITROPAN XL This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda 5 administration, plasma concentrations of R- and S-desethyloxybutynin are 73% and 92%, respectively, of concentrations observed with oxybutynin. Excretion Oxybutynin is extensively metabolized by the liver, with less than 0.1% of the administered dose excreted unchanged in the urine. Also, less than 0.1% of the administered dose is excreted as the metabolite desethyloxybutynin. Dose Proportionality Pharmacokinetic parameters of oxybutynin and desethyloxybutynin (Cmax and AUC) following administration of 5-20 mg of DITROPAN XL are dose proportional. Special Populations Geriatric: The pharmacokinetics of DITROPAN XL were similar in all patients studied (up to 78 years of age). Pediatric: The pharmacokinetics of DITROPAN XL were evaluated in 19 children aged 5-15 years with detrusor overactivity associated with a neurological condition (e.g., spina bifida). The pharmacokinetics of DITROPAN XL in these pediatric patients were consistent with those reported for adults (see Tables 1 and 2, and Figures 1 and 2 above). Gender: There are no significant differences in the pharmacokinetics of oxybutynin in healthy male and female volunteers following administration of DITROPAN XL. Race: Available data suggest that there are no significant differences in the pharmacokinetics of oxybutynin based on race in healthy volunteers following administration of DITROPAN XL. Renal Insufficiency: There is no experience with the use of DITROPAN XL in patients with renal insufficiency. Hepatic Insufficiency: There is no experience with the use of DITROPAN XL in patients with hepatic insufficiency. This label may not be the latest approved by FDA.

CLINICAL STUDIES DITROPAN XL® (oxybutynin chloride) was evaluated for the treatment of patients with overactive bladder with symptoms of urge urinary incontinence, urgency, and frequency in three controlled studies and one open label study. The majority of patients were Caucasian (89.0%) and female (91.9%) with a mean age of 59 years (range, 18 to 98 years). Entry criteria required that patients have urge or mixed incontinence (with a predominance of urge) as evidenced by ≥ 6 urge incontinence episodes per week and ≥ 10 micturitions per day. Study 1 was a fixed dose escalation design, whereas the other studies used a dose adjustment design in which each patient’s final dose was adjusted to a balance between improvement of incontinence symptoms and tolerability of side effects. Controlled studies included patients known to be responsive to oxybutynin or other anticholinergic medications, and these patients were maintained on a final dose for up to 2 weeks. The efficacy results for the three controlled trials are presented in the following tables and figures. This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda 7 INDICATIONS AND USAGE DITROPAN XL® (oxybutynin chloride) is a once-daily controlled-release tablet indicated for the treatment of overactive bladder with symptoms of urge urinary incontinence, urgency, and frequency. DITROPAN XL is also indicated in the treatment of pediatric patients aged 6 years and older with symptoms of detrusor overactivity associated with a neurological condition (e.g., spina bifida). CONTRAINDICATIONS DITROPAN XL® (oxybutynin chloride) is contraindicated in patients with urinary retention, gastric retention and other severe decreased gastrointestinal motility conditions, uncontrolled narrow-angle glaucoma and in patients who are at risk for these conditions. This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda 8 DITROPAN XL is also contraindicated in patients who have demonstrated hypersensitivity to the drug substance or other components of the product. PRECAUTIONS Central Nervous System Effects Oxybutynin is associated with anticholinergic central nervous system (CNS) effects (See ADVERSE REACTIONS). A variety of CNS anticholinergic effects have been reported, including hallucinations, agitation, confusion and somnolence. Patients should be monitored for signs of anticholinergic CNS effects, particularly in the first few months after beginning treatment or increasing the dose. If a patient experiences anticholinergic CNS effects, dose reduction or drug discontinuation should be considered. DITROPAN XL should be used with caution in patients with preexisting dementia treated with cholinesterase inhibitors due to the risk of aggravation of symptoms. General DITROPAN XL® (oxybutynin chloride) should be used with caution in patients with hepatic or renal impairment and in patients with myasthenia gravis due to the risk of symptom aggravation. Urinary Retention DITROPAN XL should be administered with caution to patients with clinically significant bladder outflow obstruction because of the risk of urinary retention (see CONTRAINDICATIONS). Gastrointestinal Disorders DITROPAN XL should be administered with caution to patients with gastrointestinal obstructive disorders because of the risk of gastric retention (see CONTRAINDICATIONS). DITROPAN XL, like other anticholinergic drugs, may decrease gastrointestinal motility and should be used with caution in patients with conditions such as ulcerative colitis and intestinal atony. DITROPAN XL should be used with caution in patients who have gastroesophageal reflux and/or who are concurrently taking drugs (such as bisphosphonates) that can cause or exacerbate esophagitis. As with any other nondeformable material, caution should be used when administering DITROPAN XL to patients with preexisting severe gastrointestinal This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda 9 narrowing (pathologic or iatrogenic). There have been rare reports of obstructive symptoms in patients with known strictures in association with the ingestion of other drugs in nondeformable controlled-release formulations. Information for Patients Patients should be informed that heat prostration (fever and heat stroke due to decreased sweating) can occur when anticholinergics such as oxybutynin chloride are administered in the presence of high environmental temperature. Because anticholinergic agents such as oxybutynin may produce drowsiness (somnolence) or blurred vision, patients should be advised to exercise caution. Patients should be informed that alcohol may enhance the drowsiness caused by anticholinergic agents such as oxybutynin. Patients should be informed that DITROPAN XL should be swallowed whole with the aid of liquids. Patients should not chew, divide, or crush tablets. The medication is contained within a nonabsorbable shell designed to release the drug at a controlled rate. The tablet shell is eliminated from the body; patients should not be concerned if they occasionally notice in their stool something that looks like a tablet. DITROPAN XL should be taken at approximately the same time each day. Drug Interactions The concomitant use of oxybutynin with other anticholinergic drugs or with other agents which produce dry mouth, constipation, somnolence (drowsiness), and/or other anticholinergic-like effects may increase the frequency and/or severity of such effects. Anticholinergic agents may potentially alter the absorption of some concomitantly administered drugs due to anticholinergic effects on gastrointestinal motility. This may be of concern for drugs with a narrow therapeutic index. Mean oxybutynin chloride plasma concentrations were approximately 2 fold higher when DITROPAN XL was administered with ketoconazole, a potent CYP3A4 inhibitor. Other inhibitors of the cytochrome P450 3A4 enzyme system, such as antimycotic agents (e.g., itraconazole and miconazole) or macrolide antibiotics (e.g., erythromycin and clarithromycin), may alter oxybutynin mean pharmacokinetic parameters (i.e., Cmax and AUC). The clinical relevance of such potential interactions is not known. Caution should be used when such drugs are co-administered. This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda 10 Carcinogenesis, Mutagenesis, Impairment of Fertility A 24-month study in rats at dosages of oxybutynin chloride of 20, 80, and 160 mg/kg/day showed no evidence of carcinogenicity. These doses are approximately 6, 25, and 50 times the maximum human exposure, based on surface area. Oxybutynin chloride showed no increase of mutagenic activity when tested in Schizosaccharomyces pompholiciformis, Saccharomyces cerevisiae, and Salmonella typhimurium test systems. Reproduction studies with oxybutynin chloride in the mouse, rat, hamster, and rabbit showed no definite evidence of impaired fertility. Pregnancy: Teratogenic Effects Pregnancy Category B Reproduction studies with oxybutynin chloride in the mouse, rat, hamster, and rabbit showed no definite evidence of impaired fertility or harm to the animal fetus. The safety of DITROPAN XL administration to women who are or who may become pregnant has not been established. Therefore, DITROPAN XL should not be given to pregnant women unless, in the judgment of the physician, the probable clinical benefits outweigh the possible hazards. Nursing Mothers It is not known whether oxybutynin is excreted in human milk. Because many drugs are excreted in human milk, caution should be exercised when DITROPAN XL is administered to a nursing woman. Pediatric Use The safety and efficacy of DITROPAN XL were studied in 60 children in a 24-week, open-label trial. Patients were aged 6-15 years, all had symptoms of detrusor overactivity in association with a neurological condition (e.g., spina bifida), all used clean intermittent catheterization, and all were current users of oxybutynin chloride. Study results demonstrated that administration of DITROPAN XL 5 to 20 mg/day was associated with an increase from baseline in mean urine volume per catheterization from 108 mL to 136 mL, an increase from baseline in mean urine volume after morning awakening from 148 mL to 189 mL, and an increase from baseline in the mean percentage of catheterizations without a leaking episode from 34% to 51%. Urodynamic results were consistent with clinical results. Administration of DITROPAN XL resulted in an increase from baseline in mean maximum cystometric This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda 11 capacity from 185 mL to 254 mL, a decrease from baseline in mean detrusor pressure at maximum cystometric capacity from 44 cm H2O to 33 cm H2O, and a reduction in the percentage of patients demonstrating uninhibited detrusor contractions (of at least 15 cm H2O) from 60% to 28%. DITROPAN XL is not recommended in pediatric patients who can not swallow the tablet whole without chewing, dividing, or crushing, or in children under the age of 6 (See DOSAGE AND ADMINISTRATION). Geriatric Use The rate and severity of anticholinergic effects reported by patients less than 65 years old and those 65 years and older were similar (see CLINICAL PHARMACOLOGY, Pharmacokinetics, Special Populations: Gender Geriatric). ADVERSE REACTIONS Adverse Events with DITROPAN XL The safety and efficacy of DITROPAN XL® (oxybutynin chloride) was evaluated in a total of 580 participants who received DITROPAN XL in 4 clinical trials (429 patients) and four pharmacokinetic studies (151 healthy volunteers). The 429 patients were treated with 5-30 mg/day for up to 4.5 months. Three of the 4 clinical trials allowed dose adjustments based on efficacy and adverse events and one was a fixed dose escalation design. Safety information is provided for 429 patients from these three controlled clinical studies and one open label study in the first column of Table 3 below. Adverse events from two additional fixed dose, active controlled, 12 week treatment duration, postmarketing studies, in which 576 patients were treated with DITROPAN XL 10 mg/day, are also listed in Table 3 (second column). The adverse events are reported regardless of causality. This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda 12 Table 3 Incidence (%) of Adverse Events Reported by ≥ 5% of Patients Using DITROPAN XL (5-30 mg/day) and % of Corresponding Adverse Events in Two Fixed Dose (10mg/day) Studies DITROPAN XL DITROPAN XL Body System Adverse Event 5-30 mg/day 10 mg/day (n=429) (n=576) General headache 10 6 asthenia 7 3 pain 7 4 Digestive dry mouth 61 29 constipation 13 7 diarrhea 9 7 nausea 9 2 dyspepsia 7 5 Nervous somnolence 12 2 dizziness 6 4 Respiratory rhinitis 6 2 Special senses blurred vision 8 1 dry eyes 6 3 Urogenital urinary tract infection 5 5 The most common adverse events reported by the 429 patients receiving 5-30 mg/day DITROPAN XL were the expected side effects of anticholinergic agents. The incidence of dry mouth was dose-related. The discontinuation rate for all adverse events was 6.8% in the 429 patients from the 4 studies of efficacy and safety who received 5-30 mg/day. The most frequent adverse event causing early discontinuation of study medication was nausea (1.9%), while discontinuation due to dry mouth was 1.2%. In addition, the following adverse events were reported by ≥1 to < 5% of all patients who received DITROPAN XL in the 6 adjustable and fixed dose efficacy and safety studies. Infections and infestations: nasopharyngitis, upper respiratory tract infection, sinusitis, bronchitis, cystitis; Psychiatric disorders: insomnia, depression, nervousness, confusional state; Nervous System Disorders: dysgeusia; Cardiac disorders: palpitations; Vascular disorders: hypertension; Respiratory, thoracic and mediastinal disorders: nasal dryness, cough, pharyngolaryngeal pain, dry throat; Gastrointestinal Disorders: gastroesophageal reflux disease, abdominal pain, loose stools, flatulence, vomiting; Skin and subcutaneous tissue disorders: dry skin, pruritis; Musculoskeletal and connective tissue disorders: back pain, arthralgia, pain in extremity; Renal and urinary disorders: urinary retention, urinary hesitation, dysuria; General disorders and administration site conditions: fatigue, edema peripheral, asthenia, chest pain; Investigations: blood pressure increased. This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda 13 Postmarketing Surveillance Because postmarketing reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure. The following additional adverse drug reactions have been reported from worldwide postmarketing experience with DITROPAN XL: Psychiatric Disorders: psychotic disorder, agitation, hallucinations; Nervous System Disorders: convulsions; Cardiac Disorders: arrhythmia; tachycardia; Vascular Disorders: flushing; Skin and Subcutaneous Tissue Disorders: rash; Renal and Urinary Disorders: impotence; Injury, poisoning and procedural complications: fall. Additional adverse events reported with some other oxybutynin chloride formulations include: cycloplegia, mydriasis, and suppression of lactation. OVERDOSAGE The continuous release of oxybutynin from DITROPAN XL® (oxybutynin chloride) should be considered in the treatment of overdosage. Patients should be monitored for at least 24 hours. Treatment should be symptomatic and supportive. Activated charcoal as well as a cathartic may be administered. Overdosage with oxybutynin chloride has been associated with anticholinergic effects including central nervous system excitation, flushing, fever, dehydration, cardiac arrhythmia, vomiting, and urinary retention. Ingestion of 100 mg oxybutynin chloride in association with alcohol has been reported in a 13-year-old boy who experienced memory loss, and a 34-year-old woman who developed stupor, followed by disorientation and agitation on awakening, dilated pupils, dry skin, cardiac arrhythmia, and retention of urine. Both patients fully recovered with symptomatic treatment. DOSAGE AND ADMINISTRATION DITROPAN XL® (oxybutynin chloride) must be swallowed whole with the aid of liquids, and must not be chewed, divided, or crushed. DITROPAN XL may be administered with or without food. Adults: The recommended starting dose of DITROPAN XL is 5 or 10 mg once daily at approximately the same time each day. Dosage may be adjusted in 5-mg increments to achieve a balance of efficacy and tolerability (up to a maximum of 30 mg/day). In general, dosage adjustment may proceed at approximately weekly intervals. This label may not be the latest approved by FDA.

28-Day Regimen Rx only Product Logo Patients should be counseled that this product does not protect against HIV-infection (AIDS) and other sexually transmitted diseases. Description OVCON® 50, 28-Day (norethindrone and ethinyl estradiol tablets, USP) provides a continuous regimen for oral contraception derived from 21 tablets composed of norethindrone and ethinyl estradiol to be followed by 7 green tablets of inert ingredients. The chemical name for norethindrone is 17-hydroxy-19-nor-17α­ pregn-4-en-20-yn-3-one and for ethinyl estradiol the chemical name is 19-nor-17α-pregna-1,3,5(10)-trien­ 20-yne-3,17-diol. The structural formulas are: Chemical Structure The active OVCON 50 tablets contain 1 mg norethindrone and 0.05 mg ethinyl estradiol. OVCON® 50, 28-Day contains the following inactive ingredients: dibasic calcium phosphate, D&C Yellow No. 10 (aluminum lake), FD&C Blue No. 1 (aluminum lake), FD&C Yellow No. 6 (aluminum lake), lactose, magnesium stearate, povidone, sodium starch glycolate, starch (corn), and talc. CLINICAL PHARMACOLOGY Combination oral contraceptives act by suppression of gonadotropins. Although the primary mechanism of this action is inhibition of ovulation, other alterations include changes in the cervical mucus (which increase the difficulty of sperm entry into the uterus) and the endometrium (which reduce the likelihood of implantation). INDICATIONS AND USAGE Oral contraceptives are indicated for the prevention of pregnancy in women who elect to use this product as a method of contraception. Oral contraceptive products such as OVCON 50, 28-Day, which contain 50 mcg of estrogen, should not be used unless medically indicated. Oral contraceptives are highly effective. Table 1 lists the typical accidental pregnancy rates for users of combination oral contraceptives and other methods of contraception. The efficacy of these contraceptive methods, except sterilization, depends upon the reliability with which they are used. Correct and consistent use of methods can result in lower failure rates.

CONTRAINDICATIONS Oral contraceptives should not be used in women who currently have the following conditions: • Thrombophlebitis or thromboembolic disorders • A past history of deep vein thrombophlebitis or thromboembolic disorders • Cerebrovascular or coronary artery disease • Known or suspected carcinoma of the breast • Carcinoma of the endometrium or other known or suspected estrogen-dependent neoplasia • Undiagnosed abnormal genital bleeding • Cholestatic jaundice of pregnancy or jaundice with prior pill use • Hepatic adenomas or carcinomas • Known or suspected pregnancy This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda WARNINGS Cigarette smoking increases the risk of serious cardiovascular side effects from oral contraceptive use. This risk increases with age and with heavy smoking (15 or more cigarettes per day) and is quite marked in women over 35 years of age. Women who use oral contraceptives should be strongly advised not to smoke. The use of oral contraceptives is associated with increased risk of several serious conditions including myocardial infarction, thromboembolism, stroke, hepatic neoplasia, and gallbladder disease, although the risk of serious morbidity or mortality is very small in healthy women without underlying risk factors. The risk of morbidity and mortality increases significantly in the presence of other underlying risk factors such as hypertension, hyperlipidemias, obesity and diabetes. Practitioners prescribing oral contraceptives should be familiar with the following information relating to these risks. The information contained in this package insert is principally based on studies carried out in patients who used oral contraceptives with higher formulations of estrogens and progestogens than those in common use today. The effect of long-term use of the oral contraceptives with lower formulations of both estrogens and progestogens remains to be determined. Throughout this labeling, epidemiological studies reported are of two types: retrospective or case control studies and prospective or cohort studies. Case control studies provide a measure of the relative risk of a disease, namely, a ratio of the incidence of a disease among oral contraceptive users to that among nonusers. The relative risk does not provide information on the actual clinical occurrence of a disease. Cohort studies provide a measure of attributable risk, which is the difference in the incidence of disease between oral contraceptive users and nonusers. The attributable risk does provide information about the actual occurrence of a disease in the population.* For further information, the reader is referred to a text on epidemiological methods. *Adapted from Stadel BB: Oral contraceptives and cardio-vascular disease.

THROMBOEMBOLIC DISORDERS AND OTHER VASCULAR PROBLEMS The physician should be alert to the earliest manifestations of thromboembolic thrombotic disorders as discussed below. Should any of these occur or be suspected the drug should be discontinued immediately. a. Myocardial Infarction An increased risk of myocardial infarction has been attributed to oral contraceptive use. This risk is primarily in smokers or women with other underlying risk factors for coronary artery disease such as hypertension, hypercholesterolemia, morbid obesity, and diabetes. The relative risk of heart attack for current oral contraceptive users has been estimated to be two to six. The risk is very low under the age of 30. Smoking in combination with oral contraceptive use has been shown to contribute substantially to the incidence of myocardial infarctions in women in their mid-thirties or older, with smoking accounting for the majority of excess cases. Mortality rates associated with circulatory disease have been shown to increase substantially in smokers over the age of 35 and nonsmokers over the age of 40 (Figure 1) among women who use oral contraceptives. This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda FIGURE 1 CIRCULATORY DISEASE MORTALITY RATES PER 100,000 WOMEN-YEARS BY AGE, SMOKING STATUS AND ORAL CONTRACEPTIVE USE Graph Layde PM, Beral V: Further analyses of mortality in oral contraceptive users: Royal College of General Practitioners’ oral contraception study. (Table 5) Lancet 1981;1:541-546. Oral contraceptives may compound the effects of well-known risk factors, such as hypertension, diabetes, hyperlipidemias, age, and obesity. In particular, some progestogens are known to decrease HDL cholesterol and cause glucose intolerance, while estrogens may create a state of hyperinsulinism. Oral contraceptives have been shown to increase blood pressure among users (see section 9 in WARNINGS). Such increases in risk factors have been associated with an increased risk of heart disease and the risk increases with the number of risk factors present. Oral contraceptives must be used with caution in women with cardiovascular disease risk factors. b. Thromboembolism An increased risk of thromboembolic and thrombotic disease associated with the use of oral contraceptives is well established. Case control studies have found the relative risk of users compared to non-users to be 3 for the first episode of superficial venous thrombosis, 4 to 11 for deep vein thrombosis or pulmonary embolism, and 1.5 to 6 for women with predisposing conditions for venous thromboembolic disease. Cohort studies have shown the relative risk to be somewhat lower, about 3 for new cases and about 4.5 for new cases requiring hospitalization. The risk of thromboembolic disease due to oral contraceptives is not related to length of use and disappears after pill use is stopped. A two- to four-fold increase in relative risk of postoperative thromboembolic complications has been reported with the use of oral contraceptives. The relative risk of venous thrombosis in women who have predisposing conditions is twice that of women without such medical conditions. If feasible, oral contraceptives should be discontinued at least four weeks prior to and for two weeks after elective surgery of a type associated with an increase in risk of thromboembolism and during and following prolonged immobilization. Since the immediate postpartum period is also associated with an increased risk of thromboembolism, oral contraceptives should be started no earlier than four to six weeks after delivery in women who elect not to breastfeed. c. Cerebrovascular diseases Oral contraceptives have been shown to increase both the relative and attributable risk of cerebrovascular events (thrombotic and hemorrhagic strokes); although, in general, the risk is greatest among older (>35 years), hypertensive women who also smoke. Hypertension was found to be a risk factor for both users and nonusers, for both types of strokes, while smoking interacted to increase the risk for hemorrhagic strokes. In a large study, the relative risk of thrombotic strokes has been shown to range from 3 for normotensive users to 14 for users with severe hypertension. The relative risk of hemorrhagic stroke is reported to be 1.2 for nonsmokers who used oral contraceptives, 2.6 for smokers who did not use oral contraceptives, 7.6 for smokers who used oral contraceptives, 1.8 for normotensive users and 25.7 for users with severe hypertension. The attributable risk is also greater in older women. This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda d. Dose-related risk of vascular disease from oral contraceptives A positive association has been observed between the amount of estrogen and progestogen in oral contraceptives and the risk of vascular disease. A decline in serum high density lipoproteins (HDL) has been reported with many progestational agents. A decline in serum high density lipoproteins has been associated with an increased incidence of ischemic heart disease. Because estrogens increase HDL cholesterol, the net effect of an oral contraceptive depends on a balance achieved between doses of estrogen and progestogen and the nature and absolute amount of progestogens used in the contraceptive. The amount of both hormones should be considered in the choice of an oral contraceptive. Minimizing exposure to estrogen and progestogen is in keeping with good principles of therapeutics. For any particular estrogen/progestogen combination, the dosage regimen prescribed should be one which contains the least amount of estrogen and progestogen that is compatible with a low failure rate and the needs of the individual patient. New acceptors of oral contraceptive agents should be started on preparations containing 0.05 mg or less of estrogen. Products containing 50 mcg estrogen should be used only when medically indicated. e. Persistence of risk There are two studies which have shown persistence of risk of vascular disease for ever-users of oral contraceptives. In a study in the United States, the risk of developing myocardial infarction after discontinuing oral contraceptives persists for at least 9 years for women 40-49 years old who had used oral contraceptives for five or more years, but this increased risk was not demonstrated in other age groups. In another study in Great Britain, the risk of developing cerebrovascular disease persisted for at least 6 years after discontinuation of oral contraceptives, although excess risk was very small. However, both studies were performed with oral contraceptive formulations containing 50 micrograms or higher of estrogens. 2. ESTIMATES OF MORTALITY FROM CONTRACEPTIVE USE One study gathered data from a variety of sources which have estimated the mortality rate associated with different methods of contraception at different ages (Table 2). TABLE 2 ANNUAL NUMBER OF BIRTH-RELATED OR METHOD-RELATED DEATHS ASSOCIATED WITH CONTROL OF FERTILITY PER 100,000 NONSTERILE WOMEN, BY FERTILITY CONTROL METHOD ACCORDING TO AGE Age Method of control 15-19 20-24 25-29 30-34 35-39 40-44 and outcome No fertility control methods* 7.0 7.4 9.1 14.8 25.7 28.2 Oral contraceptives 0.3 0.5 0.9 1.9 13.8 31.6 nonsmoker** Oral contraceptives 2.2 3.4 6.6 13.5 51.1 117.2 smoker** IUD** 0.8 0.8 1.0 1.0 1.4 1.4 Condom* 1.1 1.6 0.7 0.2 0.3 0.4 Diaphragm/spermicide* 1.9 1.2 1.2 1.3 2.2 2.8 Periodic abstinence* 2.5 1.6 1.6 1.7 2.9 3.6 *Deaths are birth related **Deaths are method related Ory HW: Mortality associated with fertility and fertility control: 1983. Fam Plann Perspect 1983; 15:50-56. These estimates include the combined risk of death associated with contraceptive methods plus the risk attributable to pregnancy in the event of method failure. Each method of contraception has its specific benefits and risk. The study concluded that with the exception of oral contraceptive users 35 and older who This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda smoke and 40 and older who do not smoke, mortality associated with all methods of birth control is low and below that associated with childbirth. The observation of a possible increase in risk of mortality with age for oral contraceptive users is based on data gathered in the 1970s – but not reported until 1983. However, current clinical practice involves the use of lower estrogen dose formulations combined with careful restriction of oral contraceptive use to women who do not have the various risk factors listed in this labeling. Because of these changes in practice and, also, because of some limited new data which suggest that the risk of cardiovascular disease with the use of oral contraceptives may now be less than previously observed (Porter JB, Hunter J, Jick H, et al. Oral contraceptives and nonfatal vascular disease. Obstet Gynecol 1985;66:1-4 and Porter JB, Jick H, Walker AM. Mortality among oral contraceptive users. Obstet Gynecol 1987;70:29-32), the Fertility and Maternal Health Drugs Advisory Committee was asked to review the topic in 1989. The Committee concluded that although cardiovascular disease risk may be increased with oral contraceptive use after age 40 in healthy nonsmoking women (even with the newer low-dose formulations), there are greater potential health risks associated with pregnancy in older women and with the alternative surgical and medical procedures which may be necessary if such women do not have access to effective and acceptable means of contraception. Therefore, the Committee recommended that the benefits of oral contraceptive use by healthy nonsmoking women over 40 may outweigh the possible risks. Of course, older women, as all women who take oral contraceptives, should take the lowest possible dose formulation that is effective. 3. CARCINOMA OF THE REPRODUCTIVE ORGANS Numerous epidemiological studies have been performed on the incidence of breast, endometrial, ovarian, and cervical cancer in women using oral contraceptives. The overwhelming evidence in the literature suggests that use of oral contraceptives is not associated with an increase in the risk of developing breast cancer, regardless of the age and parity of first use or with most of the marketed brands and doses. The Cancer and Steroid Hormone (CASH) study also showed no latent effect on the risk of breast cancer for at least a decade following long-term use. A few studies have shown a slightly increased relative risk of developing breast cancer, although the methodology of these studies, which included differences in examination of users and nonusers and differences in age at start of use, has been questioned. Some studies suggest that oral contraceptive use has been associated with an increase in the risk of cervical intraepithelial neoplasia in some populations of women. However, there continues to be controversy about the extent to which such findings may be due to differences in sexual behavior and other factors. In spite of many studies of the relationship between oral contraceptive use and breast cancer and cervical cancers, a cause-and-effect relationship has not been established. 4. HEPATIC NEOPLASIA Benign hepatic adenomas are associated with oral contraceptive use, although their occurrence is rare in the United States. Indirect calculations have estimated the attributable risk to be in the range of 3.3 cases/100,000 for users, a risk that increases after four or more years of use. Rupture of hepatic adenomas may cause death through intra-abdominal hemorrhage. Studies from Britain have shown an increased risk of developing hepatocellular carcinoma in long-term (>8 years) oral contraceptive users. However, these cancers are extremely rare in the U.S. and the attributable risk (the excess incidence) of liver cancers in oral contraceptive users approaches less than one per million users. 5. OCULAR LESIONS There have been clinical case reports of retinal thrombosis associated with the use of oral contraceptives. Oral contraceptives should be discontinued if there is unexplained partial or complete loss of vision; onset This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda of proptosis or diplopia; papilledema; or retinal vascular lesions. Appropriate diagnostic and therapeutic measures should be undertaken immediately. 6. ORAL CONTRACEPTIVE USE BEFORE OR DURING EARLY PREGNANCY Extensive epidemiological studies have revealed no increased risk of birth defects in women who have used oral contraceptives prior to pregnancy. Studies also do not suggest a teratogenic effect, particularly in so far as cardiac anomalies and limb reduction defects are concerned, when taken inadvertently during early pregnancy. The administration of oral contraceptives to induce withdrawal bleeding should not be used as a test for pregnancy. Oral contraceptives should not be used during pregnancy to treat threatened or habitual abortion. It is recommended that for any patient who has missed two consecutive periods, pregnancy should be ruled out before continuing oral contraceptive use. If the patient has not adhered to the prescribed schedule, the possibility of pregnancy should be considered at the time of the first missed period. Oral contraceptive use should be discontinued if pregnancy is confirmed. 7. GALLBLADDER DISEASE Earlier studies have reported an increased lifetime relative risk of gallbladder surgery in users of oral contraceptives and estrogens. More recent studies, however, have shown that the relative risk of developing gallbladder disease among oral contraceptive users may be minimal. The recent findings of minimal risk may be related to the use of oral contraceptive formulations containing lower hormonal doses of estrogens and progestogens. 8. CARBOHYDRATE AND LIPID METABOLIC EFFECTS Oral contraceptives have been shown to cause glucose intolerance in a significant percentage of users. Oral contraceptives containing greater than 75 micrograms of estrogens cause hyperinsulinism, while lower doses of estrogen cause less glucose intolerance. Progestogens increase insulin secretion and create insulin resistance, this effect varying with different progestational agents. However, in the nondiabetic woman, oral contraceptives appear to have no effect on fasting blood glucose. Because of these demonstrated effects, prediabetic and diabetic women should be carefully observed while taking oral contraceptives. A small proportion of women will have persistent hypertriglyceridemia while on the pill. As discussed earlier (see WARNINGS 1.a. and 1.d.), changes in serum triglycerides and lipoprotein levels have been reported in oral contraceptive users. 9. ELEVATED BLOOD PRESSURE An increase in blood pressure has been reported in women taking oral contraceptives and this increase is more likely in older oral contraceptive users and with continued use. Data from the Royal College of General Practitioners and subsequent randomized trials have shown that the incidence of hypertension increases with increasing concentrations of progestogens. Women with a history of hypertension or hypertension-related diseases, or renal disease should be encouraged to use another method of contraception. If women elect to use oral contraceptives, they should be monitored closely and if significant elevation of blood pressure occurs, oral contraceptives should be discontinued. For most women, elevated blood pressure will return to normal after stopping oral contraceptives, and there is no difference in the occurrence of hypertension among ever- and never-users. 10. HEADACHE The onset or exacerbation of migraine or development of headache with a new pattern which is recurrent, persistent, or severe requires discontinuation of oral contraceptives and evaluation of the cause. This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda 11. BLEEDING IRREGULARITIES Breakthrough bleeding and spotting are sometimes encountered in patients on oral contraceptives, especially during the first three months of use. Nonhormonal causes should be considered and adequate diagnostic measures taken to rule out malignancy or pregnancy in the event of breakthrough bleeding, as in the case of any abnormal vaginal bleeding. If pathology has been excluded, time or a change to another formulation may solve the problem. In the event of amenorrhea, pregnancy should be ruled out. Women with a history of oligomenorrhea or secondary amenorrhea or young women without regular cycles prior to taking oral contraceptives may again have irregular bleeding or amenorrhea after discontinuation of oral contraceptives. PRECAUTIONS 1. SEXUALLY-TRANSMITTED DISEASES Patients should be counseled that this product does not protect against HIV infection (AIDS) and other sexually transmitted diseases. 2. PHYSICAL EXAMINATION AND FOLLOW-UP It is good medical practice for all women to have annual history and physical examinations, including women using oral contraceptives. The physical examination, however, may be deferred until after initiation of oral contraceptives if requested by the woman and judged appropriate by the clinician. The physical examination should include special reference to blood pressure, breasts, abdomen and pelvic organs, including cervical cytology, and relevant laboratory tests. In case of undiagnosed, persistent or recurrent abnormal vaginal bleeding, appropriate measures should be conducted to rule out malignancy. Women with a strong family history of breast cancer or who have breast nodules should be monitored with particular care. 3. LIPID DISORDERS Women who are being treated for hyperlipidemias should be followed closely if they elect to use oral contraceptives. Some progestogens may elevate LDL levels and may render the control of hyperlipidemias more difficult. 4. LIVER FUNCTION If jaundice develops in any woman receiving such drugs, the medication should be discontinued. Steroid hormones may be poorly metabolized in patients with impaired liver function. 5. FLUID RETENTION Oral contraceptives may cause some degree of fluid retention. They should be prescribed with caution, and only with careful monitoring, in patients with conditions which might be aggravated by fluid retention. 6. EMOTIONAL DISORDERS Women with a history of depression should be carefully observed and the drug discontinued if depression recurs to a serious degree. Patients becoming significantly depressed while taking oral contraceptives should stop the medication and use an alternate method of contraception in an attempt to determine whether the symptom is drug related. 7. CONTACT LENSES Contact lens wearers who develop visual changes or changes in lens tolerance should be assessed by an ophthalmologist. 8. DRUG INTERACTIONS Reduced efficacy and increased incidence of breakthrough bleeding and menstrual irregularities have been associated with concomitant use of rifampin. A similar association, though less marked, has been suggested with barbiturates, phenylbutazone, phenytoin sodium, and possibly with griseofulvin, ampicillin, and tetracyclines. This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda 9. INTERACTIONS WITH LABORATORY TESTS Certain endocrine and liver function tests and blood components may be affected by oral contraceptives: a. Increased prothrombin and factors VII, VIII, IX, and X; decreased antithrombin 3; increased norepinephrine-induced platelet aggregability. b. Increased thyroid-binding globulin (TBG) leading to increased circulating total thyroid hormone, as measured by protein-bound iodine (PBI), T4 by column or by radioimmunoassay. Free T3 resin uptake is decreased, reflecting the elevated TBG, free T4 concentration is unaltered. c. Other binding proteins may be elevated in serum. d. Sex-binding globulins are increased and result in elevated levels of total circulating sex steroids and corticoids; however, free or biologically active levels remain unchanged. e. Triglycerides may be increased. f. Glucose tolerance may be decreased. g. Serum folate levels may be depressed by oral contraceptive therapy. This may be of clinical significance if a woman becomes pregnant shortly after discontinuing oral contraceptives. 10. CARCINOGENESIS See WARNINGS section. 11. PREGNANCY Pregnancy Category X. See CONTRAINDICATIONS and WARNINGS sections. 12. NURSING MOTHERS Small amounts of oral contraceptive steroids have been identified in the milk of nursing mothers and a few adverse effects on the child have been reported, including jaundice and breast enlargement. In addition, oral contraceptives given in the postpartum period may interfere with lactation by decreasing the quantity and quality of breast milk. If possible, the nursing mother should be advised not to use oral contraceptives but to use other forms of contraception until she has completely weaned her child. 13. VOMITING AND/OR DIARRHEA Although a cause-and-effect relationship has not been clearly established, several cases of oral contraceptive failure have been reported in association with vomiting and/or diarrhea. If significant gastrointestinal disturbance occurs in any woman receiving contraceptive steroids, the use of a back-up method of contraception for the remainder of that cycle is recommended. 14. PEDIATRIC USE Safety and efficacy of OVCON 50 (norethindrone and ethinyl estradiol tablets, USP) have been established in women of reproductive age. Safety and efficacy are expected to be the same in postpubertal adolescents under the age of 16 years and in users ages 16 years and older. Use of this product before menarche is not indicated.

For current labeling information, please visit https://www.fda.gov/drugsatfda OVERDOSAGE Serious ill effects have not been reported following acute ingestion of large doses of oral contraceptives by young children. Overdosage may cause nausea, and withdrawal bleeding may occur in females. NONCONTRACEPTIVE HEALTH EFFECTS The following noncontraceptive health benefits related to the use of oral contraceptives are supported by epidemiological studies which largely utilized oral contraceptive formulations containing estrogen doses exceeding 0.035 mg of ethinyl estradiol or 0.05 mg of mestranol. Effects on menses: • Increased menstrual cycle regularity • Decreased blood loss and decreased incidence of iron deficiency anemia • Decreased incidence of dysmenorrhea Effects related to inhibition of ovulation: • Decreased incidence of functional ovarian cysts • Decreased incidence of ectopic pregnancies Effects from long-term use: • Decreased incidence of fibroadenomas and fibrocystic disease of the breast • Decreased incidence of acute pelvic inflammatory disease • Decreased incidence of endometrial cancer • Decreased incidence of ovarian cancer DOSAGE AND ADMINISTRATION The following is a summary of the instructions given to the patient in the “HOW TO TAKE THE PILL” section of the DETAILED PATIENT PACKAGE INSERT. The patient is given instructions in five (5) categories. 1. IMPORTANT POINTS TO REMEMBER: The patient is told (a) that she should take one pill every day at the same time, (b) many women have spotting or light bleeding or gastric distress during the first one to three cycles, (c) missing pills can also cause spotting or light bleeding, (d) she should use a back-up method for contraception if she has vomiting or diarrhea or takes some concomitant medications, and/or if she has trouble remembering the pill, (e) if she has any other questions, she should consult her physician. 2. BEFORE SHE STARTS TAKING HER PILLS: She should decide what time of day she wishes to take the pill, check whether her pill pack has 21 or 28 pills, and note the order in which she should take the pills (diagrammatic drawings of the pill pack are included in the patient insert). 3. WHEN SHE SHOULD START THE FIRST PACK: The Day-One start is listed as the first choice and the Sunday start (the Sunday after her period starts) is given as the second choice. If she uses the Sunday start she should use a back-up method in the first cycle if she has intercourse before she has taken seven pills. 4. WHAT TO DO DURING THE CYCLE: The patient is advised to take one pill at the same time every day until the pack is empty. If she is on a 21-day regimen, she should wait seven days to start the next pack. If she is on the 28-day regimen, she should start the next pack the day after the last inactive tablet and not wait any days between packs. 5. WHAT TO DO IF SHE MISSES A PILL OR PILLS: The patient is given instructions about what she should do if she misses one, two or more than two pills at varying times in her cycle for both the Day-One and the Sunday start. The patient is warned that she may become pregnant if she has unprotected intercourse in the seven days. To avoid this, she must use another birth control method such as condom, foam, or sponge in these seven days. This label may not be the latest approved by FDA.

For current labeling information, please visit https://www.fda.gov/drugsatfda PATIENT PACKAGE INSERT BRIEF SUMMARY This product (like all oral contraceptives) is intended to prevent pregnancy. It does not protect against HIV infection (AIDS) and other sexually transmitted diseases. Oral contraceptives, also known as “birth control pills” or “the pill”, are taken to prevent pregnancy and when taken correctly, have a failure rate of about 1% per year when used without missing any pills. The typical failure rate of large numbers of pill users is less than 3% per year when women who miss pills are included. Oral contraceptive use is associated with certain serious diseases that can be life-threatening or may cause temporary or permanent disability. The risks associated with taking oral contraceptives increase significantly if you: • Smoke • Have high blood pressure, diabetes, high cholesterol • Have or have had clotting disorders, heart attack, stroke, angina pectoris, cancer of the breast or sex organs, jaundice or malignant or benign liver tumors. You should not take the pill if you suspect you are pregnant or have unexplained vaginal bleeding. Cigarette smoking increases the risk of serious cardiovascular side effects from oral contraceptive use. This risk increases with age and with heavy smoking (15 or more cigarettes per day) and is quite marked in women over 35 years of age. Women who use oral contraceptives are strongly advised not to smoke. Most side effects of the pill are not serious. The most common such effects are nausea, vomiting, bleeding between menstrual periods, weight gain, breast tenderness, and difficulty wearing contact lenses. These side effects, especially nausea and vomiting, may subside within the first three months of use. The serious side effects of the pill occur very infrequently, especially if you are in good health and are young. However, you should know that the following medical conditions have been associated with or made worse by the pill: 1. Blood clots in the legs (thrombophlebitis), lungs (pulmonary embolism), stoppage or rupture of a blood vessel in the brain (stroke), blockage of blood vessels in the heart (heart attack or angina pectoris), or other organs of the body. As mentioned above, smoking increases the risk of heart attacks and strokes and subsequent serious medical consequences. 2. Liver tumors, which may rupture and cause severe bleeding. A possible but not definite association has been found with the pill and liver cancer. However, liver cancers are extremely rare. The chance of developing liver cancer from using the pill is thus even rarer. 3. High blood pressure, although blood pressure usually returns to normal when the pill is stopped. The symptoms associated with these serious side effects are discussed in the Detailed Patient Package Insert given to you with your supply of pills. Notify your doctor or healthcare provider if you notice any unusual physical disturbances while taking the pill. In addition, drugs such as rifampin, as well as some anticonvulsants and some antibiotics may decrease oral contraceptive effectiveness. Studies to date of women taking the pill have not shown an increase in the incidence of cancer of the breast or cervix. There is, however, insufficient evidence to rule out the possibility that the pill may cause such cancers. Taking the pill provides some important noncontraceptive effects. These include less painful menstruation, less menstrual blood loss and anemia, fewer pelvic infections, and fewer cancers of the ovary and the lining of the uterus. Be sure to discuss any medical condition you may have with your healthcare provider. Your healthcare provider will take a medical and family history before prescribing oral contraceptives and will examine This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda you. The physical examination may be delayed to another time if you request it and the healthcare provider believes that it is a good medical practice to postpone it. You should be reexamined at least once a year while taking oral contraceptives. The Detailed Patient Package Insert gives you further information which you should read and discuss with your healthcare professional. DOSAGE AND ADMINISTRATION HOW TO TAKE THE PILL IMPORTANT POINTS TO REMEMBER SEXUALLY-TRANSMITTED DISEASES This product (like all oral contraceptives) is intended to prevent pregnancy. It does not protect against transmission of HIV (AIDS) and other sexually transmitted diseases such as Chlamydia, genital herpes, genital warts, gonorrhea, hepatitis B, and syphilis. BEFORE YOU START TAKING YOUR PILLS: 1. BE SURE TO READ THESE DIRECTIONS: Before you start taking your pills. Anytime you are not sure what to do. 2. THE RIGHT WAY TO TAKE THE PILL IS TO TAKE ONE PILL EVERY DAY AT THE SAME TIME. If you miss pills you could get pregnant. This includes starting the pack late. The more pills you miss, the more likely you are to get pregnant. 3. MANY WOMEN HAVE SPOTTING OR LIGHT BLEEDING, OR MAY FEEL SICK TO THEIR STOMACH DURING THE FIRST 1–3 PACKS OF PILLS. If you do feel sick to your stomach, do not stop taking the pill. The problem will usually go away. If it doesn’t go away, check with your doctor or clinic. 4. MISSING PILLS CAN ALSO CAUSE SPOTTING OR LIGHT BLEEDING, even when you make up these missed pills. On the days you take 2 pills to make up for missed pills, you could also feel a little sick to your stomach. 5. IF YOU HAVE VOMITING OR DIARRHEA, for any reason, or IF YOU TAKE SOME MEDICINES, including some antibiotics, your pills may not work as well. Use a back-up method (such as condoms, foam, or sponge) until you check with your doctor or clinic. 6. IF YOU HAVE TROUBLE REMEMBERING TO TAKE THE PILL, talk to your doctor or clinic about how to make pill-taking easier or about using another method of birth control. 7. IF YOU HAVE ANY QUESTIONS OR ARE UNSURE ABOUT THE INFORMATION IN THIS LEAFLET, call your doctor or clinic. BEFORE YOU START TAKING YOUR PILLS 1. DECIDE WHAT TIME OF DAY YOU WANT TO TAKE YOUR PILL. It is important to take it at about the same time every day. 2. LOOK AT YOUR PILL PACK: The 28-pill pack has 21 “active” yellow pills (with hormones) to take for 3 weeks, followed by 1 week of “reminder” green pills (without hormones). 3. BE SURE TO HAVE READY AT ALL TIMES: ANOTHER KIND OF BIRTH CONTROL (such as condoms, foam, or sponge) to use as a back­ up in case you miss pills. AN EXTRA, FULL PILL PACK. This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda Package Illustration Each of the 21 yellow pills contains norethindrone (1 mg) and ethinyl estradiol (0.05 mg). Each green pill in the 28-day regimen contains inert ingredients. WHEN TO START THE FIRST PACK OF PILLS You have a choice of which day to start taking your first pack of pills. Decide with your doctor or clinic which is the best day for you. Once you have decided which day you will begin taking your pills, immediately do the following: remove the Brief Summary from the cellophane pouch and look for the Day Label Sheet attached; peel the label from the sheet which has the start day printed on the left-hand side; affix the label to the blister card in the designated location. Take your pill daily in the order indicated by the week number in the illustration above. Pick a time of day which will be easy to remember. DAY 1 START: 1. Take the first “active” yellow pill of the first pack during the first 24 hours of your period. 2. You will not need to use a back-up method of birth control, since you are starting the pill at the beginning of your period. SUNDAY START: 1. Take the first “active” yellow pill of the first pack on the Sunday after your period starts, even if you are still bleeding. If your period begins on Sunday, start the pack that same day. 2. Use another method of birth control as a back-up method if you have sex anytime from the Sunday you start your first pack until the next Sunday (7 days). Condoms, foam, or the sponge are good back-up methods of birth control. This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda WHAT TO DO DURING THE MONTH 1. TAKE ONE PILL AT THE SAME TIME EVERY DAY UNTIL THE PACK IS EMPTY. Do not skip pills even if you are spotting or bleeding between monthly periods or feel sick to your stomach (nausea). Do not skip pills even if you do not have sex very often. 2. WHEN YOU FINISH A PACK OR SWITCH YOUR BRAND OF PILLS: 28 pills: Start the next pack on the day after your last “reminder” pill. Do not wait any days between packs. WHAT TO DO IF YOU MISS PILLS If you MISS 1 yellow “active” pill: 1. Take it as soon as you remember. Take the next pill at your regular time. This means you may take 2 pills in 1 day. 2. You do not need to use a back-up birth control method if you have sex. If you MISS 2 yellow “active” pills in a row in WEEK 1 OR WEEK 2 of your pack: 1. Take 2 pills on the day you remember and 2 pills the next day. 2. Then take 1 pill a day until you finish the pack. 3. You MAY BECOME PREGNANT if you have sex in the 7 days after you miss pills. You MUST use another birth control method (such as condoms, foam, or sponge) as a back-up for those 7 days. If you MISS 2 yellow “active” pills in a row in THE 3rd WEEK: If you are a Day 1 Starter: 1. THROW OUT the rest of the pill pack and start a new pack that same day. If you are a Sunday Starter: Keep taking 1 pill every day until Sunday. On Sunday, THROW OUT the rest of the pack and start a new pack of pills that same day. 2. You may not have your period this month but this is expected. However, if you miss your period 2 months in a row, call your doctor or clinic because you might be pregnant. 3. You MAY BECOME PREGNANT if you have sex in the 7 days after you miss pills. You MUST use another birth control method (such as condoms, foam, or sponge) as a back-up for those 7 days. If you MISS 3 OR MORE yellow “active” pills in a row (during the first 3 weeks): 1. If you are a Day 1 Starter: THROW OUT the rest of the pill pack and start a new pack that same day. If you are a Sunday Starter: Keep taking 1 pill every day until Sunday. On Sunday, THROW OUT the rest of the pack and start a new pack of pills that same day. 2. You may not have your period this month but this is expected. However, if you miss your period 2 months in a row, call your doctor or clinic because you might be pregnant. 3. You MAY BECOME PREGNANT if you have sex in the 7 days after you miss pills. You MUST use another birth control method (such as condoms, foam, or sponge) as a back-up for those 7 days. A REMINDER FOR THOSE ON 28-DAY PACKS: If you forget any of the 7 green “reminder” pills in Week 4: THROW AWAY the pills you missed. Keep taking 1 pill each day until the pack is empty. You do not need a back-up method. This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda FINALLY, IF YOU ARE STILL NOT SURE WHAT TO DO ABOUT THE PILLS YOU HAVE MISSED: Use a BACK-UP METHOD anytime you have sex. KEEP TAKING ONE “ACTIVE” PILL EACH DAY until you can reach your doctor or clinic. This product (like all oral contraceptives) is intended to prevent pregnancy.

INTRODUCTION You should not use OVCON 50 (norethindrone and ethinyl estradiol tablets, USP), 28-Day, which contains higher doses of estrogen than other oral contraceptives, unless specifically recommended by your healthcare provider. Any woman who considers using oral contraceptives (the “birth control pill” or “the pill”) should understand the benefits and risks of using this form of birth control. Although the oral contraceptives have important advantages over other methods of contraception, they have certain risks that no other method has and some of these risks may continue after you have stopped using the oral contraceptive. This booklet will give you much of the information you will need to make this decision and will also help you determine if you are at risk of developing any of the serious side effects of the pill. It will tell you how to use the pill properly so that it will be as effective as possible. However, this booklet is not a replacement for a careful discussion between you and your healthcare professional. You should discuss the information provided in this booklet with him or her, both when you first start taking the pill and during your revisits. You should also follow your healthcare professional’s advice with regard to regular check-ups while you are on the pill. EFFECTIVENESS OF ORAL CONTRACEPTIVES Oral contraceptives or “birth control pills” or “the pill” are used to prevent pregnancy and are more effective than other nonsurgical methods of birth control. The chance of becoming pregnant is less than 1% (1 pregnancy per 100 women per year of use) when the pills are used correctly and no pills are missed. Typical failure rates are actually 3% per year. The chance of becoming pregnant increases with each missed pill during a menstrual cycle. In comparison, typical accidental pregnancy rates for other nonsurgical methods of birth control during the first year of use are as follows: IUD: 3% Diaphragm with spermicides: 18% Spermicides alone: 21% Vaginal sponge: 18% to 28% Condom alone: 12% Periodic abstinence: 20% Injectable progestogen: 0.3% to 0.4% Implants: 0.03% to 0.04% No methods: 85%. WHO SHOULD NOT TAKE ORAL CONTRACEPTIVES Cigarette smoking increases the risk of serious cardiovascular side effects from oral contraceptive use. This risk increases with age and with heavy smoking (15 or more cigarettes per day) and is quite marked in women over 35 years of age. Women who use oral contraceptives should not smoke. Some women should not use the pill. For example, you should not take the pill if you are pregnant or think you may be pregnant. You should also not use the pill if you have or have ever had any of the following conditions: • A history of heart attack or stroke • Blood clots in the legs (thrombophlebitis), lungs (pulmonary embolism), or eyes • A history of blood clots in the deep veins of your legs • Chest pain (angina pectoris) This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda • Known or suspected breast cancer or cancer of the lining of the uterus • Unexplained vaginal bleeding (until a diagnosis is reached by your doctor) • Yellowing of the whites of the eyes or of the skin (jaundice) during pregnancy or during previous use of the pill • Liver tumor (benign or cancerous) Tell your healthcare professional if you have ever had any of these conditions. Your healthcare professional can recommend a safer method of birth control. OTHER CONSIDERATIONS BEFORE TAKING ORAL CONTRACEPTIVES Tell your healthcare professional if you have: • Breast nodules, fibrocystic disease of the breast or an abnormal breast x-ray or mammogram • Diabetes • Elevated cholesterol or triglycerides • High blood pressure • Migraine or other headaches or epilepsy • Mental depression • Gallbladder, heart, or kidney disease • History of scanty or irregular menstrual periods Women with any of these conditions should be checked often by their healthcare professional if they choose to use oral contraceptives. Also, be sure to inform your doctor or healthcare professional if you smoke or are on any medications. RISKS OF TAKING ORAL CONTRACEPTIVES 1. Risk of developing blood clots Blood clots and blockage of blood vessels are the most serious side effects of taking oral contraceptives. In particular, a clot in the legs can cause thrombophlebitis and a clot that travels to the lungs can cause a sudden blocking of the vessel carrying blood to the lungs. Either of these can cause death or disability. Rarely, clots occur in the blood vessels of the eye and may cause blindness, double vision, or impaired vision. If you take oral contraceptives and need elective surgery, need to stay in bed for a prolonged illness, or have recently delivered a baby, you may be at risk of developing blood clots. You should consult your doctor about stopping oral contraceptives three to four weeks before surgery and not taking oral contraceptives for two weeks after surgery or during bed rest. You should also not take oral contraceptives soon after delivery of a baby. It is advisable to wait for at least four weeks after delivery if you are not breastfeeding. If you are breastfeeding see the section on breastfeeding in General Precautions. 2. Heart attacks and strokes Oral contraceptives may increase the tendency to develop strokes (stoppage or rupture of blood vessels in the brain) and angina pectoris and heart attacks (blockage of blood vessels in the heart). Any of these conditions can cause death or disability. Smoking greatly increases the possibility of suffering heart attacks and strokes. Furthermore, smoking and the use of oral contraceptives greatly increase the chances of developing and dying of heart disease. 3. Gallbladder disease Oral contraceptive users probably have a greater risk than nonusers of having gallbladder disease, although this risk may be related to pills containing high doses of estrogens. 4. Liver tumors In rare cases, oral contraceptives can cause benign but dangerous liver tumors. These benign liver tumors can rupture and cause fatal internal bleeding. In addition, a possible, but not definite, association has been This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda found with the pill and liver cancers in two studies, in which a few women who developed these very rare cancers were found to have used oral contraceptives for long periods. However, liver cancers in general are extremely rare and the chance of developing liver cancer from using the pill is thus even rarer. 5. Cancer of the reproductive organs There is, at present, no confirmed evidence that oral contraceptives increase the risk of cancer of the reproductive organs and breasts in human studies. Several studies have found no overall increase in the risk of developing breast cancer. However, women who use oral contraceptives and have a strong family history of breast cancer, or who have breast nodules or abnormal mammograms, should be closely followed by their doctors. Some studies have found an increase in the incidence of cancer of the cervix in women who use oral contraceptives. However, this finding may be related to factors other than the use of oral contraceptives. ESTIMATED RISK OF DEATH FROM A BIRTH CONTROL METHOD OR PREGNANCY All methods of birth control and pregnancy are associated with a risk of developing certain diseases which may lead to disability or death. An estimate of the number of deaths associated with different methods of birth control and pregnancy has been calculated and is shown in the following table. ANNUAL NUMBER OF BIRTH-RELATED OR METHOD-RELATED DEATHS ASSOCIATED WITH CONTROL OF FERTILITY PER 100,000 NONSTERILE WOMEN, BY FERTILITY CONTROL METHOD ACCORDING TO AGE Age Method of control 15-19 20-24 25-29 30-34 35-39 40-44 and outcome No fertility control methods* 7.0 7.4 9.1 14.8 25.7 28.2 Oral contraceptives 0.3 0.5 0.9 1.9 13.8 31.6 nonsmoker** Oral contraceptives 2.2 3.4 6.6 13.5 51.1 117.2 smoker** IUD** 0.8 0.8 1.0 1.0 1.4 1.4 Condom* 1.1 1.6 0.7 0.2 0.3 0.4 Diaphragm/spermicide* 1.9 1.2 1.2 1.3 2.2 2.8 Periodic abstinence* 2.5 1.6 1.6 1.7 2.9 3.6 *Deaths are birth related **Deaths are method related It can be seen in the table that for women aged 15 to 39, the risk of death was highest with pregnancy (7-26 deaths per 100,000 women, depending on age). Among pill users who do not smoke, the risk of death was always lower than that associated with pregnancy for any age group, although over the age of 40, the risk increases to 32 deaths per 100,000 women, compared to 28 associated with pregnancy at that age. However, for pill users who smoke and are over the age of 35, the estimated number of deaths exceeds those for other methods of birth control. If a woman is over the age of 40 and smokes, her estimated risk of death is four times higher (117/100,000 women) than the estimated risk associated with pregnancy (28/100,000 women) in that age group. The suggestion that women over 40 who don’t smoke should not take oral contraceptives is based on information from older high-dose pills and on less selective use of pills than is practiced today. An Advisory Committee of the FDA discussed this issue in 1989 and recommended that the benefits of oral contraceptive use by healthy, nonsmoking women over 40 years of age may outweigh the possible risks. However, all women, especially older women, are cautioned to use the lowest dose pill that is effective. This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda In the above table, the risk of death from any birth control method is less than the risk of childbirth, except for oral contraceptive users over the age of 35 who smoke and pill users over the age of 40 even if they do not smoke. You should discuss this information with your healthcare professional. WARNING SIGNALS If any of these adverse conditions occur while you are taking oral contraceptives, call your doctor immediately: • Sharp chest pain, coughing of blood, or sudden shortness of breath (indicating a possible clot in the lung) • Pain in the calf (indicating a possible clot in the leg) • Crushing chest pain or heaviness in the chest (indicating a possible heart attack) • Sudden severe headache or vomiting, dizziness or fainting, disturbances of vision or speech, weakness, or numbness in an arm or leg (indicating a possible stroke) • Sudden partial or complete loss of vision (indicating a possible clot in the eye) • Breast lumps (indicating possible breast cancer or fibrocystic disease of the breast; ask your doctor or healthcare professional to show you how to examine your breasts) • Severe pain or tenderness in the stomach area (indicating a possibly ruptured liver tumor) • Difficulty in sleeping, weakness, lack of energy, fatigue, or change in mood (possibly indicating severe depression) • Jaundice or a yellowing of the skin or eyeballs, accompanied frequently by fever, fatigue, loss of appetite, dark-colored urine, or light-colored bowel movements (indicating possible liver problems) • Abnormal vaginal bleeding (see SIDE EFFECTS OF ORAL CONTRACEPTIVES, 1. Vaginal bleeding.) SIDE EFFECTS OF ORAL CONTRACEPTIVES In addition to the risks and more serious side effects discussed above (see RISKS OF TAKING ORAL CONTRACEPTIVES, ESTIMATED RISK OF DEATH FROM A BIRTH CONTROL METHOD OR PREGNANCY and WARNING SIGNALS sections), the following may also occur: 1. Vaginal bleeding Irregular vaginal bleeding or spotting may occur while you are taking the pills. Irregular bleeding may vary from slight staining between menstrual periods to breakthrough bleeding which is a flow much like a regular period. Irregular bleeding occurs most often during the first few months of oral contraceptive use, but may also occur after you have been taking the pill for some time. Such bleeding may be temporary and usually does not indicate any serious problems. It is important to continue taking your pills on schedule. If the bleeding occurs in more than one cycle or lasts for more than a few days, talk to your doctor or healthcare professional. 2. Gastrointestinal effects The most frequent, unpleasant side effects are nausea and vomiting, stomach cramps, bloating, and a change in appetite. 3. Contact lenses If you wear contact lenses and notice a change in vision or an inability to wear your lenses, contact your doctor or healthcare professional. 4. Fluid retention Oral contraceptives may cause edema (fluid retention) with swelling of the fingers or ankles and may raise your blood pressure. If you experience fluid retention, contact your doctor or healthcare professional. 5. Melasma A spotty darkening of the skin is possible, particularly of the face. This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda 6. Other side effects Other side effects may include change in appetite, headache, nervousness, depression, dizziness, loss of scalp hair, rash, and vaginal infections. If any of these side effects bother you, call your doctor or healthcare professional. GENERAL PRECAUTIONS 1. Missed periods and use of oral contraceptives before or during early pregnancy There may be times when you may not menstruate regularly after you have completed taking a cycle of pills. If you have taken your pills regularly and miss one menstrual period, continue taking your pills for the next cycle but be sure to inform your healthcare professional before doing so. If you have not taken the pills daily as instructed and missed a menstrual period, or if you missed two consecutive menstrual periods, you may be pregnant. Check with your healthcare professional immediately to determine whether you are pregnant. Do not continue to take oral contraceptives until you are sure you are not pregnant, but continue to use another method of contraception. There is no conclusive evidence that oral contraceptive use is associated with an increase in birth defects, when taken inadvertently during early pregnancy. Previously, a few studies had reported that oral contraceptives might be associated with birth defects, but these studies have not been confirmed. Nevertheless, oral contraceptives or any other drugs should not be used during pregnancy unless clearly necessary and prescribed by your doctor. You should check with your doctor about risks to your unborn child of any medication taken during pregnancy. 2. While breastfeeding If you are breastfeeding, consult your doctor before starting oral contraceptives. Some of the drug will be passed on to the child in the milk. A few adverse effects on the child have been reported, including yellowing of the skin (jaundice) and breast enlargement. In addition, oral contraceptives may decrease the amount and quality of your milk. If possible, do not use oral contraceptives while breastfeeding. You should use another method of contraception since breastfeeding provides only partial protection from becoming pregnant and this partial protection decreases significantly as you breastfeed for longer periods of time. You should consider starting oral contraceptives only after you have weaned your child completely. 3. Laboratory tests If you are scheduled for any laboratory tests, tell your doctor you are taking birth control pills. Certain blood tests may be affected by birth control pills. 4. Drug interactions Certain drugs may interact with birth control pills to make them less effective in preventing pregnancy or cause an increase in breakthrough bleeding. Such drugs include rifampin, drugs used for epilepsy such as barbiturates (for example, phenobarbital) and phenytoin (Dilantin® is one brand of this drug), phenylbutazone (Butazolidin® is one brand) and possibly ampicillin and tetracyclines (several brand names). You may need to use an additional method of contraception when you take drugs which can make oral contraceptives less effective. This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda DOSAGE AND ADMINISTRATION HOW TO TAKE THE PILL IMPORTANT POINTS TO REMEMBER SEXUALLY-TRANSMITTED DISEASES This product (like all oral contraceptives) is intended to prevent pregnancy. It does not protect against transmission of HIV (AIDS) and other sexually transmitted diseases such as Chlamydia, genital herpes, genital warts, gonorrhea, hepatitis B, and syphilis. BEFORE YOU START TAKING YOUR PILLS: 1. BE SURE TO READ THESE DIRECTIONS: Before you start taking your pills. Anytime you are not sure what to do. 2. THE RIGHT WAY TO TAKE THE PILL IS TO TAKE ONE PILL EVERY DAY AT THE SAME TIME. If you miss pills you could get pregnant. This includes starting the pack late. The more pills you miss, the more likely you are to get pregnant. 3. MANY WOMEN HAVE SPOTTING OR LIGHT BLEEDING, OR MAY FEEL SICK TO THEIR STOMACH DURING THE FIRST 1-3 PACKS OF PILLS. If you do feel sick to your stomach, do not stop taking the pill. The problem will usually go away. If it doesn’t go away, check with your doctor or clinic. 4. MISSING PILLS CAN ALSO CAUSE SPOTTING OR LIGHT BLEEDING, even when you make up these missed pills. On the days you take 2 pills to make up for missed pills, you could also feel a little sick to your stomach. 5. IF YOU HAVE VOMITING OR DIARRHEA, for any reasons, or IF YOU TAKE SOME MEDICINES, including some antibiotics, your pills may not work as well. Use a back-up method (such as condoms, foam, or sponge) until you check with your doctor or clinic. 6. IF YOU HAVE TROUBLE REMEMBERING TO TAKE THE PILL, talk to your doctor or clinic about how to make pill-taking easier or about using another method of birth control. 7. IF YOU HAVE ANY QUESTIONS OR ARE UNSURE ABOUT THE INFORMATION IN THIS LEAFLET, call your doctor or clinic. BEFORE YOU START TAKING YOUR PILLS 1. DECIDE WHAT TIME OF DAY YOU WANT TO TAKE YOUR PILL. It is important to take it at about the same time every day. 2. LOOK AT YOUR PILL PACK The 28-pill pack has 21 “active” yellow pills (with hormones) to take for 3 weeks, followed by 1 week of “reminder” green pills (without hormones). This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda Package Illustration Each of the 21 yellow pills contains norethindrone (1 mg) and ethinyl estradiol (0.05 mg). Each green pill in the 28-day regimen contains inert ingredients. 3. BE SURE YOU HAVE READY AT ALL TIMES: ANOTHER KIND OF BIRTH CONTROL (such as condoms, foam, or sponge) to use as a back­ up in case you miss pills. AN EXTRA, FULL PILL PACK. WHEN TO START THE FIRST PACK OF PILLS You have a choice of which day to start taking your first pack of pills. Decide with your doctor or clinic which is the best day for you. Once you have decided which day you will begin taking your pills, immediately do the following: remove the Brief Summary from the cellophane pouch and look for the Day Label Sheet attached; peel the label from the sheet which has the start day printed on the left-hand side; affix the label to the blister card in the designated location. Take your pill daily in the order indicated by the week number in the illustration above. Pick a time of day which will be easy to remember. This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda DAY 1 START: 1. Take the first “active” yellow pill of the first pack during the first 24 hours of your period. 2. You will not need to use a back-up method of birth control, since you are starting the pill at the beginning of your period. SUNDAY START: 1. Take the first “active” yellow pill of the first pack on the Sunday after your period starts, even if you are still bleeding. If your period begins on Sunday, start the pack that same day. 2. Use another method of birth control as a back-up method if you have sex anytime from the Sunday you start your first pack until the next Sunday (7 days). Condoms, foam, or the sponge are good back-up methods of birth control. WHAT TO DO DURING THE MONTH 1. TAKE ONE PILL AT THE SAME TIME EVERY DAY UNTIL THE PACK IS EMPTY. Do not skip pills even if you are spotting or bleeding between monthly periods or feel sick to your stomach (nausea). Do not skip pills even if you do not have sex very often. 2. WHEN YOU FINISH A PACK OR SWITCH YOUR BRAND OF PILLS: 21 pills: Wait 7 days to start the next pack. You will probably have your period during that week. Be sure that no more than 7 days pass between 21-day packs. 28 pills: Start the next pack on the day after your last “reminder” pill. Do not wait any days between packs. WHAT TO DO IF YOU MISS PILLS If you MISS 1 yellow “active” pill: 1. Take it as soon as you remember. Take the next pill at your regular time. This means you may take 2 pills in 1 day. 2. You do not need to use a back-up birth control method if you have sex. If you MISS 2 yellow “active” pills in a row in WEEK 1 or WEEK 2 of your pack: 1. Take 2 pills on the day you remember and 2 pills the next day. 2. Then take 1 pill a day until you finish the pack. 3. You MAY BECOME PREGNANT if you have sex in the 7 days after you miss pills. You MUST use another birth control method (such as condoms, foam, or sponge) as a back-up for those 7 days. If you MISS 2 yellow “active” pills in a row in THE 3rd WEEK: 1. If you are a Day 1 Starter: THROW OUT the rest of the pill pack and start a new pack that same day. If you are a Sunday Starter: Keep taking 1 pill every day until Sunday. On Sunday, THROW OUT the rest of the pack and start a new pack of pills that same day. 2. You may not have your period this month but this is expected. However, if you miss your period 2 months in a row, call your doctor or clinic because you might be pregnant. 3. You MAY BECOME PREGNANT if you have sex in the 7 days after you miss pills. You MUST use another birth control method (such as condoms, foam, or sponge) as a back-up for those 7 days. If you MISS 3 OR MORE yellow “active” pills in a row (during the first 3 weeks): 1. If you are a Day 1 Starter: THROW OUT the rest of the pill pack and start a new pack that same day. If you are a Sunday Starter: Keep taking 1 pill every day until Sunday. On Sunday, THROW OUT the rest of the pack and start a new pack of pills that same day. This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda 2. You may not have your period this month but this is expected. However, if you miss your period 2 months in a row, call your doctor or clinic because you might be pregnant. 3. You MAY BECOME PREGNANT if you have sex in the 7 days after you miss pills. You MUST use another birth control method (such as condoms, foam, or sponge) as a back-up for those 7 days. A REMINDER FOR THOSE ON 28-DAY PACKS: If you forget any of the 7 green “reminder” pills in Week 4: THROW AWAY the pills you missed. Keep taking 1 pill each day until the pack is empty. You do not need a back-up method. FINALLY, IF YOU ARE STILL NOT SURE WHAT TO DO ABOUT THE PILLS YOU HAVE MISSED: Use a BACK-UP METHOD anytime you have sex. KEEP TAKING ONE “ACTIVE” PILL EACH DAY until you can reach your doctor or clinic. GENERAL 1. Pregnancy due to pill failure The incidence of pill failure resulting in pregnancy is approximately 1% (i.e., one pregnancy per 100 women per year) if taken every day as directed, but more typical failure rates are about 3%. If failure does occur, the risk to the fetus is minimal. 2. Pregnancy after stopping the pill There may be some delay in becoming pregnant after you stop using oral contraceptives, especially if you had irregular menstrual cycles before you used oral contraceptives. It may be advisable to postpone conception until you begin menstruating regularly once you have stopped taking the pill and desire pregnancy. There does not appear to be any increase in birth defects in newborn babies when pregnancy occurs soon after stopping the pill. 3. Other a. Overdosage Serious ill effects have not been reported following ingestion of large doses of oral contraceptives by young children. Overdosage may cause nausea and withdrawal bleeding in females. In case of overdosage, contact your poison control center, healthcare professional, or nearest emergency room. KEEP THIS DRUG AND ALL DRUGS OUT OF THE REACH OF CHILDREN. b. General medical information Your healthcare professional will take a medical and family history before prescribing oral contraceptives and will examine you. The physical examination may be delayed to another time if you request it and the healthcare provider believes that it is a good medical practice to postpone it. You should be reexamined at least once a year. Be sure to inform your healthcare professional if there is a family history of any of the conditions listed previously in this leaflet. Be sure to keep all appointments with your healthcare professional, because this is a time to determine if there are early signs of side effects of oral contraceptive use. Do not use this drug for any condition other than the one for which it was prescribed. This drug has been prescribed specifically for you; do not give it to others who may want birth control pills. This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda NONCONTRACEPTIVE EFFECTS OF ORAL CONTRACEPTIVES In addition to preventing pregnancy, use of oral contraceptives may provide certain benefits. They are: • Menstrual cycles may become more regular • Blood flow during menstruation may be lighter and less iron may be lost. Therefore, anemia due to iron deficiency is less likely to occur. • Pain or other symptoms during menstruation may be encountered less frequently • Ectopic (tubal) pregnancy may occur less frequently • Noncancerous cysts or lumps in the breast may occur less frequently • Acute pelvic inflammatory disease may occur less frequently • Oral contraceptive use may provide some protection against developing two forms of cancer: cancer of the ovaries and cancer of the lining of the uterus. If you want more information about birth control pills, ask your doctor or pharmacist. They have a more technical leaflet called the Professional Labeling, which you may wish to read.

DITROPAN (oxybutynin chloride) Tablets DESCRIPTION Each scored biconvex, engraved blue DITROPAN (oxybutynin chloride) Tablet contains 5 mg of oxybutynin chloride. Chemically, oxybutynin chloride is d,l (racemic) 4-diethylamino-2-butynyl phenylcyclohexylglycolate hydrochloride. The empirical formula of oxybutynin chloride is C22H31NO3HCl. The structural formula appears below: structural formula Oxybutynin chloride is a white crystalline solid with a molecular weight of 393.9. It is readily soluble in water and acids, but relatively insoluble in alkalis. DITROPAN Tablets also contain calcium stearate, FD&C Blue #1 Lake, lactose, and microcrystalline cellulose. DITROPAN Tablets are for oral administration. Therapeutic Category: Antispasmodic, anticholinergic. CLINICAL PHARMACOLOGY Oxybutynin chloride exerts a direct antispasmodic effect on smooth muscle and inhibits the muscarinic action of acetylcholine on smooth muscle. Oxybutynin chloride exhibits only one fifth of the anticholinergic activity of atropine on the rabbit detrusor muscle, but four to ten times the antispasmodic activity. No blocking effects occur at skeletal neuromuscular junctions or autonomic ganglia (antinicotinic effects). Oxybutynin chloride relaxes bladder smooth muscle. In patients with conditions characterized by involuntary bladder contractions, cystometric studies have demonstrated that oxybutynin chloride increases bladder (vesical) capacity, diminishes the frequency of uninhibited contractions of the detrusor muscle, and delays the initial desire to void. Oxybutynin chloride thus decreases urgency and the frequency of both incontinent episodes and voluntary urination. Antimuscarinic activity resides predominately in the R-isomer. A metabolite, desethyloxybutynin, has pharmacological activity similar to that of oxybutynin in in vitro studies. Reference ID: 2996984 1 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda Pharmacokinetics Absorption Following oral administration of DITROPAN, oxybutynin is rapidly absorbed achieving Cmax within an hour, following which plasma concentration decreases with an effective half-life of approximately 2 to 3 hours. The absolute bioavailability of oxybutynin is reported to be about 6% (range 1.6 to 10.9%) for the tablets. Wide interindividual variation in pharmacokinetic parameters is evident following oral administration of oxybutynin. The mean pharmacokinetic parameters for R- and S-oxybutynin are summarized in Table 1. The plasma concentration-time profiles for R- and S-oxybutynin are similar in shape; Figure 1 shows the profile for R-oxybutynin.

For current labeling information, please visit https://www.fda.gov/drugsatfda Food Effects Data in the literature suggests that oxybutynin solution co-administered with food resulted in a slight delay in absorption and an increase in its bioavailability by 25% (n=18)1. Distribution Plasma concentrations of oxybutynin decline biexponentially following intravenous or oral administration. The volume of distribution is 193 L after intravenous administration of 5 mg oxybutynin chloride. Metabolism Oxybutynin is metabolized primarily by the cytochrome P450 enzyme systems, particularly CYP3A4 found mostly in the liver and gut wall. Its metabolic products include phenylcyclohexylglycolic acid, which is pharmacologically inactive, and desethyloxybutynin, which is pharmacologically active. Excretion Oxybutynin is extensively metabolized by the liver, with less than 0.1% of the administered dose excreted unchanged in the urine. Also, less than 0.1% of the administered dose is excreted as the metabolite desethyloxybutynin. CLINICAL STUDIES DITROPAN was well tolerated in patients administered the drug in controlled studies of 30 days’ duration and in uncontrolled studies in which some of the patients received the drug for 2 years. INDICATIONS AND USAGE DITROPAN (oxybutynin chloride) is indicated for the relief of symptoms of bladder instability associated with voiding in patients with uninhibited neurogenic or reflex neurogenic bladder (i.e., urgency, frequency, urinary leakage, urge incontinence, dysuria). CONTRAINDICATIONS DITROPAN (oxybutynin chloride) is contraindicated in patients with urinary retention, gastric retention and other severe decreased gastrointestinal motility conditions, uncontrolled narrow-angle glaucoma and in patients who are at risk for these conditions. DITROPAN is also contraindicated in patients who have demonstrated hypersensitivity to the drug substance or other components of the product. Reference ID: 2996984 4 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda WARNINGS Angioedema of the face, lips, tongue and/or larynx has been reported with oxybutynin. In some cases, angioedema occurred after the first dose. Angioedema associated with upper airway swelling may be life-threatening. If involvement of the tongue, hypopharynx, or larynx occurs, oxybutynin should be promptly discontinued and appropriate therapy and/or measures necessary to ensure a patent airway should be promptly provided. PRECAUTIONS Central Nervous System Effects Oxybutynin is associated with anticholinergic central nervous system (CNS) effects (See ADVERSE REACTIONS). A variety of CNS anticholinergic effects have been reported, including hallucinations, agitation, confusion and somnolence. Patients should be monitored for signs of anticholinergic CNS effects, particularly in the first few months after beginning treatment or increasing the dose. If a patient experiences anticholinergic CNS effects, dose reduction or drug discontinuation should be considered. DITROPAN should be used with caution in patients with preexisting dementia treated with cholinesterase inhibitors due to the risk of aggravation of symptoms. General DITROPAN (oxybutynin chloride) should be used with caution in the frail elderly, in patients with hepatic or renal impairment, and in patients with myasthenia gravis. DITROPAN may aggravate the symptoms of hyperthyroidism, coronary heart disease, congestive heart failure, cardiac arrhythmias, hiatal hernia, tachycardia, hypertension, myasthenia gravis, and prostatic hypertrophy. Urinary Retention DITROPAN should be administered with caution to patients with clinically significant bladder outflow obstruction because of the risk of urinary retention (see CONTRAINDICATIONS). Gastrointestinal Disorders DITROPAN should be administered with caution to patients with gastrointestinal obstructive disorders because of the risk of gastric retention (see CONTRAINDICATIONS). Reference ID: 2996984 5 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda Administration of DITROPAN to patients with ulcerative colitis may suppress intestinal motility to the point of producing a paralytic ileus and precipitate or aggravate toxic megacolon, a serious complication of the disease. DITROPAN, like other anticholinergic drugs, may decrease gastrointestinal motility and should be used with caution in patients with conditions such as ulcerative colitis, and intestinal atony. DITROPAN should be used with caution in patients who have gastroesophageal reflux and/or who are concurrently taking drugs (such as bisphosphonates) that can cause or exacerbate esophagitis. Information for Patients Patients should be informed that oxybutynin may produce angioedema that could result in life-threatening airway obstruction. Patients should be advised to promptly discontinue oxybutynin therapy and seek immediate medical attention if they experience edema of the tongue, edema of the laryngopharynx, or difficulty breathing. Patients should be informed that heat prostration (fever and heat stroke due to decreased sweating) can occur when anticholinergics such as oxybutynin chloride are administered in the presence of high environmental temperature. Because anticholinergic agents such as oxybutynin may produce drowsiness (somnolence), or blurred vision, patients should be advised to exercise caution. Patients should be informed that alcohol may enhance the drowsiness caused by anticholinergic agents such as oxybutynin. Drug Interactions The concomitant use of oxybutynin with other anticholinergic drugs or with other agents which produce dry mouth, constipation, somnolence (drowsiness), and/or other anticholinergic-like effects may increase the frequency and/or severity of such effects. Anticholinergic agents may potentially alter the absorption of some concomitantly administered drugs due to anticholinergic effects on gastrointestinal motility. This may be of concern for drugs with a narrow therapeutic index. Mean oxybutynin chloride plasma concentrations were approximately 3-4 fold higher when DITROPAN was administered with ketoconazole, a potent CYP3A4 inhibitor. Reference ID: 2996984 6 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda Other inhibitors of the cytochrome P450 3A4 enzyme system, such as antimycotic agents (e.g., itraconazole and miconazole) or macrolide antibiotics (e.g., erythromycin and clarithromycin), may alter oxybutynin mean pharmacokinetic parameters (i.e., Cmax and AUC). The clinical relevance of such potential interactions is not known. Caution should be used when such drugs are co-administered. Carcinogenesis, Mutagenesis, Impairment of Fertility A 24-month study in rats at dosages of oxybutynin chloride of 20, 80, and 160 mg/kg/day showed no evidence of carcinogenicity. These doses are approximately 6, 25, and 50 times the maximum human exposure, based on surface area. Oxybutynin chloride showed no increase of mutagenic activity when tested in Schizosaccharomyces pompholiciformis, Saccharomyces cerevisiae and Salmonella typhimurium test systems. Reproduction studies using oxybutynin chloride in the hamster, rabbit, rat, and mouse have shown no definite evidence of impaired fertility. Pregnancy Category B. Reproduction studies using oxybutynin chloride in the hamster, rabbit, rat, and mouse have shown no definite evidence of impaired fertility or harm to the animal fetus. The safety of DITROPAN administered to women who are or who may become pregnant has not been established. Therefore, DITROPAN should not be given to pregnant women unless, in the judgment of the physician, the probable clinical benefits outweigh the possible hazards. Nursing Mothers It is not known whether this drug is excreted in human milk. Because many drugs are excreted in human milk, caution should be exercised when DITROPAN is administered to a nursing woman. Pediatric Use The safety and efficacy of DITROPAN administration have been demonstrated for pediatric patients 5 years of age and older (see DOSAGE AND ADMINISTRATION). The safety and efficacy of DITROPAN Tablets were studied in 30 children in a 24­ week, open-label trial. Patients were aged 5-15 years, all had symptoms of detrusor overactivity in association with a neurological condition (e.g., spina bifida), all used clean intermittent catheterization, and all were current users of oxybutynin chloride. Reference ID: 2996984 7 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda Study results demonstrated that the administration of DITROPAN was associated with improvement in clinical and urodynamic parameters. At total daily doses ranging from 5 mg to 15 mg, treatment with DITROPAN Tablets was associated with an increase from baseline in mean urine volume per catheterization from 122 mL to 145 mL, an increase from baseline in mean urine volume after morning awakening from 148 mL to 168 mL, and an increase from baseline in the mean percentage of catheterizations without a leaking episode from 43% to 61%. Urodynamic results in these patients were consistent with the clinical results. Treatment with DITROPAN Tablets was associated with an increase from baseline in maximum cystometric capacity from 230 mL to 279 mL, a decrease from baseline in mean detrusor pressure at maximum cystometric capacity from 36 cm H20 to 33 cm H20, and a reduction in the percentage of patients demonstrating uninhibited detrusor contractions (of at least 15 cm H20) from 39% to 20%. As there is insufficient clinical data for pediatric populations under age 5, DITROPAN is not recommended for this age group. Geriatric Use Clinical studies of DITROPAN did not include sufficient numbers of subjects age 65 and over to determine whether they respond differently from younger patients. Other reported clinical experience has not identified differences in responses between healthy elderly and younger patients; however, a lower initial starting dose of 2.5 mg given 2 or 3 times a day has been recommended for the frail elderly due to a prolongation of the elimination half-life from 2-3 hours to 5 hours.2,3,4 In general, dose selection for an elderly patient should be cautious, usually starting at the low end of the dosing range, reflecting the greater frequency of decreased hepatic, renal, or cardiac function, and of concomitant disease or other drug therapy. ADVERSE REACTIONS The safety and efficacy of DITROPAN (oxybutynin chloride) was evaluated in a total of 199 patients in three clinical trials. These participants were treated with DITROPAN 5-20 mg/day for up to 6 weeks. Table 3 shows the incidence of adverse events judged by investigators to be at least possibly related to treatment and reported by at least 5% of patients.

The incidence of dry mouth was dose-related. In addition, the following adverse events were reported by 1 to <5% of patients using DITROPAN (5-20 mg/day) in all studies. Infections and Infestations: nasopharyngitis, upper respiratory tract infection, bronchitis, cystitis, fungal infection; Metabolism and Nutrition Disorders: fluid retention; Psychiatric Disorders: confusional state; Nervous System Disorders: dysgeusia, sinus headache; Eye Disorders: keratoconjunctivitis sicca, eye irritation; Cardiac Disorders: palpitations, sinus arrhythmia; Vascular Disorders: flushing; Respiratory, Thoracic and Mediastinal Disorders: nasal dryness, cough, pharyngolaryngeal pain, dry throat, sinus congestion, hoarseness, asthma, nasal congestion; Gastrointestinal Disorders: diarrhea, abdominal pain, loose stools, flatulence, vomiting, abdominal pain upper, dysphagia, aptyalism, eructation, tongue coated; Skin and Subcutaneous Tissue Disorders: dry skin, pruritis; Musculoskeletal and Connective Tissue Disorders: back pain, arthralgia, pain in extremity, flank pain; Renal and Urinary Disorders: dysuria, pollakiuria; General Disorders and Administration Site Conditions: fatigue, edema peripheral, asthenia, pain, thirst, edema; Investigations: blood pressure increased, blood glucose increased, blood pressure decreased; Injury, Poisoning, and Procedural Complications: fall. Postmarketing Surveillance Because postmarketing adverse events are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure. The following additional adverse events have been reported from worldwide postmarketing experience with Reference ID: 2996984 9 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda DITROPAN: Psychiatric Disorders: psychotic disorder, agitation, hallucination, memory impairment; Nervous System Disorders: convulsions; Eye Disorders: cycloplegia, mydriasis; Cardiac Disorders: tachycardia, QT interval prolongation; Gastrointestinal Disorders: decreased gastrointestinal motility; Skin and Subcutaneous Tissue Disorders: rash, decreased sweating; Renal and Urinary Disorders: impotence; Reproductive System and Breast Disorders: Suppression of lactation; General Disorders and Administration Site Conditions: hypersensitivity reactions, including angioedema with airway obstruction, urticaria, and face edema; rare anaphylactic reactions requiring hospitalization for emergency treatment. OVERDOSAGE Treatment should be symptomatic and supportive. Activated charcoal as well as a cathartic may be administered. Overdosage with oxybutynin chloride has been associated with anticholinergic effects including central nervous system excitation (e.g., restlessness, tremor, irritability, convulsions, delirium, hallucinations), flushing, fever, dehydration, cardiac arrhythmia, vomiting, and urinary retention. Other symptoms may include hypotension or hypertension, respiratory failure, paralysis, and coma. Ingestion of 100 mg oxybutynin chloride in association with alcohol has been reported in a 13-year-old boy who experienced memory loss, and a 34 year old woman who developed stupor, followed by disorientation and agitation on awakening, dilated pupils, dry skin, cardiac arrhythmia, and retention of urine. Both patients fully recovered with symptomatic treatment. DOSAGE AND ADMINISTRATION Adults: The usual dose is one 5-mg tablet two to three times a day. The maximum recommended dose is one 5-mg tablet four times a day. A lower starting dose of 2.5 mg two or three times a day is recommended for the frail elderly. Pediatric patients over 5 years of age: The usual dose is one 5-mg tablet two times a day. The maximum recommended dose is one 5-mg tablet three times a day.

DITROPAN (oxybutynin chloride) Tablets DESCRIPTION Each scored biconvex, engraved blue DITROPAN (oxybutynin chloride) Tablet contains 5 mg of oxybutynin chloride. Chemically, oxybutynin chloride is d,l (racemic) 4-diethylamino-2-butynyl phenylcyclohexylglycolate hydrochloride. The empirical formula of oxybutynin chloride is C22H31NO3HCl. The structural formula appears below: structural formula Oxybutynin chloride is a white crystalline solid with a molecular weight of 393.9. It is readily soluble in water and acids, but relatively insoluble in alkalis. DITROPAN Tablets also contain calcium stearate, FD&C Blue #1 Lake, lactose, and microcrystalline cellulose. DITROPAN Tablets are for oral administration. Therapeutic Category: Antispasmodic, anticholinergic. CLINICAL PHARMACOLOGY Oxybutynin chloride exerts a direct antispasmodic effect on smooth muscle and inhibits the muscarinic action of acetylcholine on smooth muscle. Oxybutynin chloride exhibits only one fifth of the anticholinergic activity of atropine on the rabbit detrusor muscle, but four to ten times the antispasmodic activity. No blocking effects occur at skeletal neuromuscular junctions or autonomic ganglia (antinicotinic effects). Oxybutynin chloride relaxes bladder smooth muscle. In patients with conditions characterized by involuntary bladder contractions, cystometric studies have demonstrated that oxybutynin chloride increases bladder (vesical) capacity, diminishes the frequency of uninhibited contractions of the detrusor muscle, and delays the initial desire to void. Oxybutynin chloride thus decreases urgency and the frequency of both incontinent episodes and voluntary urination. Antimuscarinic activity resides predominately in the R-isomer. A metabolite, desethyloxybutynin, has pharmacological activity similar to that of oxybutynin in in vitro studies. Reference ID: 3059351 1 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda Pharmacokinetics Absorption Following oral administration of DITROPAN, oxybutynin is rapidly absorbed achieving Cmax within an hour, following which plasma concentration decreases with an effective half-life of approximately 2 to 3 hours. The absolute bioavailability of oxybutynin is reported to be about 6% (range 1.6 to 10.9%) for the tablets. Wide interindividual variation in pharmacokinetic parameters is evident following oral administration of oxybutynin. The mean pharmacokinetic parameters for R- and S-oxybutynin are summarized in Table 1. The plasma concentration-time profiles for R- and S-oxybutynin are similar in shape; Figure 1 shows the profile for R-oxybutynin.

For current labeling information, please visit https://www.fda.gov/drugsatfda Distribution Oxybutynin is widely distributed in body tissues following systemic absorption. The volume of distribution is 193 L after intravenous administration of 5 mg oxybutynin chloride. Both enantiomers of oxybutynin are highly bound (>99%) to plasma proteins. Both enantiomers of desethyloxybutynin are also highly bound (>97%) to plasma proteins. The major binding protein is alpha-1 acid glycoprotein. Metabolism Oxybutynin is metabolized primarily by the cytochrome P450 enzyme systems, particularly CYP3A4 found mostly in the liver and gut wall. Its metabolic products include phenylcyclohexylglycolic acid, which is pharmacologically inactive, and desethyloxybutynin, which is pharmacologically active. Excretion Oxybutynin is extensively metabolized by the liver, with less than 0.1% of the administered dose excreted unchanged in the urine. Also, less than 0.1% of the administered dose is excreted as the metabolite desethyloxybutynin. CLINICAL STUDIES DITROPAN was well tolerated in patients administered the drug in controlled studies of 30 days’ duration and in uncontrolled studies in which some of the patients received the drug for 2 years. INDICATIONS AND USAGE DITROPAN (oxybutynin chloride) is indicated for the relief of symptoms of bladder instability associated with voiding in patients with uninhibited neurogenic or reflex neurogenic bladder (i.e., urgency, frequency, urinary leakage, urge incontinence, dysuria). CONTRAINDICATIONS DITROPAN (oxybutynin chloride) is contraindicated in patients with urinary retention, gastric retention and other severe decreased gastrointestinal motility conditions, uncontrolled narrow-angle glaucoma and in patients who are at risk for these conditions. DITROPAN is also contraindicated in patients who have demonstrated hypersensitivity to the drug substance or other components of the product. WARNINGS Angioedema of the face, lips, tongue and/or larynx has been reported with oxybutynin. In some cases, angioedema occurred after the first dose. Angioedema Reference ID: 3059351 4 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda associated with upper airway swelling may be life-threatening. If involvement of the tongue, hypopharynx, or larynx occurs, oxybutynin should be promptly discontinued and appropriate therapy and/or measures necessary to ensure a patent airway should be promptly provided. PRECAUTIONS Central Nervous System Effects Oxybutynin is associated with anticholinergic central nervous system (CNS) effects (See ADVERSE REACTIONS). A variety of CNS anticholinergic effects have been reported, including hallucinations, agitation, confusion and somnolence. Patients should be monitored for signs of anticholinergic CNS effects, particularly in the first few months after beginning treatment or increasing the dose. If a patient experiences anticholinergic CNS effects, dose reduction or drug discontinuation should be considered. DITROPAN should be used with caution in patients with preexisting dementia treated with cholinesterase inhibitors due to the risk of aggravation of symptoms. General DITROPAN (oxybutynin chloride) should be used with caution in the frail elderly, in patients with hepatic or renal impairment, and in patients with myasthenia gravis. DITROPAN may aggravate the symptoms of hyperthyroidism, coronary heart disease, congestive heart failure, cardiac arrhythmias, hiatal hernia, tachycardia, hypertension, myasthenia gravis, and prostatic hypertrophy. Urinary Retention DITROPAN should be administered with caution to patients with clinically significant bladder outflow obstruction because of the risk of urinary retention (see CONTRAINDICATIONS). Gastrointestinal Disorders DITROPAN should be administered with caution to patients with gastrointestinal obstructive disorders because of the risk of gastric retention (see CONTRAINDICATIONS). Administration of DITROPAN to patients with ulcerative colitis may suppress intestinal motility to the point of producing a paralytic ileus and precipitate or aggravate toxic megacolon, a serious complication of the disease. 5 Reference ID: 3059351 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda DITROPAN, like other anticholinergic drugs, may decrease gastrointestinal motility and should be used with caution in patients with conditions such as ulcerative colitis, and intestinal atony. DITROPAN should be used with caution in patients who have gastroesophageal reflux and/or who are concurrently taking drugs (such as bisphosphonates) that can cause or exacerbate esophagitis. Information for Patients Patients should be informed that oxybutynin may produce angioedema that could result in life-threatening airway obstruction. Patients should be advised to promptly discontinue oxybutynin therapy and seek immediate medical attention if they experience edema of the tongue, edema of the laryngopharynx, or difficulty breathing. Patients should be informed that heat prostration (fever and heat stroke due to decreased sweating) can occur when anticholinergics such as oxybutynin chloride are administered in the presence of high environmental temperature. Because anticholinergic agents such as oxybutynin may produce drowsiness (somnolence), or blurred vision, patients should be advised to exercise caution. Patients should be informed that alcohol may enhance the drowsiness caused by anticholinergic agents such as oxybutynin. Drug Interactions The concomitant use of oxybutynin with other anticholinergic drugs or with other agents which produce dry mouth, constipation, somnolence (drowsiness), and/or other anticholinergic-like effects may increase the frequency and/or severity of such effects. Anticholinergic agents may potentially alter the absorption of some concomitantly administered drugs due to anticholinergic effects on gastrointestinal motility. This may be of concern for drugs with a narrow therapeutic index. Mean oxybutynin chloride plasma concentrations were approximately 3-4 fold higher when DITROPAN was administered with ketoconazole, a potent CYP3A4 inhibitor. Other inhibitors of the cytochrome P450 3A4 enzyme system, such as antimycotic agents (e.g., itraconazole and miconazole) or macrolide antibiotics (e.g., erythromycin and clarithromycin), may alter oxybutynin mean pharmacokinetic parameters (i.e., Cmax and AUC). The clinical relevance of such potential interactions is not known. Caution should be used when such drugs are co-administered. 6 Reference ID: 3059351 This label may not be the latest approved by FDA.

For current labeling information, please visit https://www.fda.gov/drugsatfda baseline in the mean percentage of catheterizations without a leaking episode from 43% to 61%. Urodynamic results in these patients were consistent with the clinical results. Treatment with DITROPAN Tablets was associated with an increase from baseline in maximum cystometric capacity from 230 mL to 279 mL, a decrease from baseline in mean detrusor pressure at maximum cystometric capacity from 36 cm H20 to 33 cm H20, and a reduction in the percentage of patients demonstrating uninhibited detrusor contractions (of at least 15 cm H20) from 39% to 20%. As there is insufficient clinical data for pediatric populations under age 5, DITROPAN is not recommended for this age group. Geriatric Use Clinical studies of DITROPAN did not include sufficient numbers of subjects age 65 and over to determine whether they respond differently from younger patients.

DITROPAN (oxybutynin chloride) Tablets DESCRIPTION Each scored biconvex, engraved blue DITROPAN (oxybutynin chloride) Tablet contains 5 mg of oxybutynin chloride. Chemically, oxybutynin chloride is d,l (racemic) 4-diethylamino-2-butynyl phenylcyclohexylglycolate hydrochloride. The empirical formula of oxybutynin chloride is C22H31NO3HCl. The structural formula appears below: structural formula Oxybutynin chloride is a white crystalline solid with a molecular weight of 393.9. It is readily soluble in water and acids, but relatively insoluble in alkalis. DITROPAN Tablets also contain calcium stearate, FD&C Blue #1 Lake, lactose, and microcrystalline cellulose. DITROPAN Tablets are for oral administration. Therapeutic Category: Antispasmodic, anticholinergic. CLINICAL PHARMACOLOGY Oxybutynin chloride exerts a direct antispasmodic effect on smooth muscle and inhibits the muscarinic action of acetylcholine on smooth muscle. Oxybutynin chloride exhibits only one fifth of the anticholinergic activity of atropine on the rabbit detrusor muscle, but four to ten times the antispasmodic activity. No blocking effects occur at skeletal neuromuscular junctions or autonomic ganglia (antinicotinic effects). Oxybutynin chloride relaxes bladder smooth muscle. In patients with conditions characterized by involuntary bladder contractions, cystometric studies have demonstrated that oxybutynin chloride increases bladder (vesical) capacity, diminishes the frequency of uninhibited contractions of the detrusor muscle, and delays the initial desire to void. Oxybutynin chloride thus decreases urgency and the frequency of both incontinent episodes and voluntary urination. Antimuscarinic activity resides predominately in the R-isomer. A metabolite, desethyloxybutynin, has pharmacological activity similar to that of oxybutynin in in vitro studies. 1 Reference ID: 3105471 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda Pharmacokinetics Absorption Following oral administration of DITROPAN, oxybutynin is rapidly absorbed achieving Cmax within an hour, following which plasma concentration decreases with an effective half-life of approximately 2 to 3 hours. The absolute bioavailability of oxybutynin is reported to be about 6% (range 1.6 to 10.9%) for the tablets. Wide interindividual variation in pharmacokinetic parameters is evident following oral administration of oxybutynin. The mean pharmacokinetic parameters for R- and S-oxybutynin are summarized in Table 1. The plasma concentration-time profiles for R- and S-oxybutynin are similar in shape; Figure 1 shows the profile for R-oxybutynin.

For current labeling information, please visit https://www.fda.gov/drugsatfda Distribution Oxybutynin is widely distributed in body tissues following systemic absorption. The volume of distribution is 193 L after intravenous administration of 5 mg oxybutynin chloride. Both enantiomers of oxybutynin are highly bound (>99%) to plasma proteins. Both enantiomers of desethyloxybutynin are also highly bound (>97%) to plasma proteins. The major binding protein is alpha-1 acid glycoprotein. Metabolism Oxybutynin is metabolized primarily by the cytochrome P450 enzyme systems, particularly CYP3A4 found mostly in the liver and gut wall. Its metabolic products include phenylcyclohexylglycolic acid, which is pharmacologically inactive, and desethyloxybutynin, which is pharmacologically active. Excretion Oxybutynin is extensively metabolized by the liver, with less than 0.1% of the administered dose excreted unchanged in the urine. Also, less than 0.1% of the administered dose is excreted as the metabolite desethyloxybutynin. CLINICAL STUDIES DITROPAN was well tolerated in patients administered the drug in controlled studies of 30 days’ duration and in uncontrolled studies in which some of the patients received the drug for 2 years. INDICATIONS AND USAGE DITROPAN (oxybutynin chloride) is indicated for the relief of symptoms of bladder instability associated with voiding in patients with uninhibited neurogenic or reflex neurogenic bladder (i.e., urgency, frequency, urinary leakage, urge incontinence, dysuria). CONTRAINDICATIONS DITROPAN (oxybutynin chloride) is contraindicated in patients with urinary retention, gastric retention and other severe decreased gastrointestinal motility conditions, uncontrolled narrow-angle glaucoma and in patients who are at risk for these conditions. DITROPAN is also contraindicated in patients who have demonstrated hypersensitivity to the drug substance or other components of the product. WARNINGS Angioedema of the face, lips, tongue and/or larynx has been reported with oxybutynin. In some cases, angioedema occurred after the first dose. Angioedema Reference ID: 3105471 4 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda associated with upper airway swelling may be life-threatening. If involvement of the tongue, hypopharynx, or larynx occurs, oxybutynin should be promptly discontinued and appropriate therapy and/or measures necessary to ensure a patent airway should be promptly provided. PRECAUTIONS Central Nervous System Effects Oxybutynin is associated with anticholinergic central nervous system (CNS) effects (See ADVERSE REACTIONS). A variety of CNS anticholinergic effects have been reported, including hallucinations, agitation, confusion and somnolence. Patients should be monitored for signs of anticholinergic CNS effects, particularly in the first few months after beginning treatment or increasing the dose. If a patient experiences anticholinergic CNS effects, dose reduction or drug discontinuation should be considered. DITROPAN should be used with caution in patients with preexisting dementia treated with cholinesterase inhibitors due to the risk of aggravation of symptoms. General DITROPAN (oxybutynin chloride) should be used with caution in the frail elderly, in patients with hepatic or renal impairment, and in patients with myasthenia gravis. DITROPAN may aggravate the symptoms of hyperthyroidism, coronary heart disease, congestive heart failure, cardiac arrhythmias, hiatal hernia, tachycardia, hypertension, myasthenia gravis, and prostatic hypertrophy. Urinary Retention DITROPAN should be administered with caution to patients with clinically significant bladder outflow obstruction because of the risk of urinary retention (see CONTRAINDICATIONS). Gastrointestinal Disorders DITROPAN should be administered with caution to patients with gastrointestinal obstructive disorders because of the risk of gastric retention (see CONTRAINDICATIONS). Administration of DITROPAN to patients with ulcerative colitis may suppress intestinal motility to the point of producing a paralytic ileus and precipitate or aggravate toxic megacolon, a serious complication of the disease. 5 Reference ID: 3105471 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda DITROPAN, like other anticholinergic drugs, may decrease gastrointestinal motility and should be used with caution in patients with conditions such as ulcerative colitis, and intestinal atony. DITROPAN should be used with caution in patients who have gastroesophageal reflux and/or who are concurrently taking drugs (such as bisphosphonates) that can cause or exacerbate esophagitis. Information for Patients Patients should be informed that oxybutynin may produce angioedema that could result in life-threatening airway obstruction. Patients should be advised to promptly discontinue oxybutynin therapy and seek immediate medical attention if they experience edema of the tongue, edema of the laryngopharynx, or difficulty breathing. Patients should be informed that heat prostration (fever and heat stroke due to decreased sweating) can occur when anticholinergics such as oxybutynin chloride are administered in the presence of high environmental temperature. Because anticholinergic agents such as oxybutynin may produce drowsiness (somnolence), or blurred vision, patients should be advised to exercise caution. Patients should be informed that alcohol may enhance the drowsiness caused by anticholinergic agents such as oxybutynin. Drug Interactions The concomitant use of oxybutynin with other anticholinergic drugs or with other agents which produce dry mouth, constipation, somnolence (drowsiness), and/or other anticholinergic-like effects may increase the frequency and/or severity of such effects. Anticholinergic agents may potentially alter the absorption of some concomitantly administered drugs due to anticholinergic effects on gastrointestinal motility. This may be of concern for drugs with a narrow therapeutic index. Mean oxybutynin chloride plasma concentrations were approximately 3-4 fold higher when DITROPAN was administered with ketoconazole, a potent CYP3A4 inhibitor. Other inhibitors of the cytochrome P450 3A4 enzyme system, such as antimycotic agents (e.g., itraconazole and miconazole) or macrolide antibiotics (e.g., erythromycin and clarithromycin), may alter oxybutynin mean pharmacokinetic parameters (i.e., Cmax and AUC). The clinical relevance of such potential interactions is not known. Caution should be used when such drugs are co-administered. 6 Reference ID: 3105471 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda Carcinogenesis, Mutagenesis, Impairment of Fertility A 24-month study in rats at dosages of oxybutynin chloride of 20, 80, and 160 mg/kg/day showed no evidence of carcinogenicity. These doses are approximately 6, 25, and 50 times the maximum human exposure, based on surface area. Oxybutynin chloride showed no increase of mutagenic activity when tested in Schizosaccharomyces pompholiciformis, Saccharomyces cerevisiae and Salmonella typhimurium test systems. Reproduction studies using oxybutynin chloride in the hamster, rabbit, rat, and mouse have shown no definite evidence of impaired fertility. Pregnancy Category B. Reproduction studies using oxybutynin chloride in the hamster, rabbit, rat, and mouse have shown no definite evidence of impaired fertility or harm to the animal fetus. The safety of DITROPAN administered to women who are or who may become pregnant has not been established. Therefore, DITROPAN should not be given to pregnant women unless, in the judgment of the physician, the probable clinical benefits outweigh the possible hazards. Nursing Mothers It is not known whether this drug is excreted in human milk. Because many drugs are excreted in human milk, caution should be exercised when DITROPAN is administered to a nursing woman. Pediatric Use The safety and efficacy of DITROPAN administration have been demonstrated for pediatric patients 5 years of age and older (see DOSAGE AND ADMINISTRATION). The safety and efficacy of DITROPAN Tablets were studied in 30 children in a 24­ week, open-label trial. Patients were aged 5-15 years, all had symptoms of detrusor overactivity in association with a neurological condition (e.g., spina bifida), all used clean intermittent catheterization, and all were current users of oxybutynin chloride. Study results demonstrated that the administration of DITROPAN was associated with improvement in clinical and urodynamic parameters. At total daily doses ranging from 5 mg to 15 mg, treatment with DITROPAN Tablets was associated with an increase from baseline in mean urine volume per catheterization from 122 mL to 145 mL, an increase from baseline in mean urine volume after morning awakening from 148 mL to 168 mL, and an increase from Reference ID: 3105471 7 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda baseline in the mean percentage of catheterizations without a leaking episode from 43% to 61%. Urodynamic results in these patients were consistent with the clinical results. Treatment with DITROPAN Tablets was associated with an increase from baseline in maximum cystometric capacity from 230 mL to 279 mL, a decrease from baseline in mean detrusor pressure at maximum cystometric capacity from 36 cm H2O to 33 cm H2O, and a reduction in the percentage of patients demonstrating uninhibited detrusor contractions (of at least 15 cm H2O) from 39% to 20%. As there is insufficient clinical data for pediatric populations under age 5, DITROPAN is not recommended for this age group. Geriatric Use Clinical studies of DITROPAN did not include sufficient numbers of subjects age 65 and over to determine whether they respond differently from younger patients. Other reported clinical experience has not identified differences in responses between healthy elderly and younger patients; however, a lower initial starting dose of 2.5 mg given 2 or 3 times a day has been recommended for the frail elderly due to a prolongation of the elimination half-life from 2-3 hours to 5 hours.2,3,4 In general, dose selection for an elderly patient should be cautious, usually starting at the low end of the dosing range, reflecting the greater frequency of decreased hepatic, renal, or cardiac function, and of concomitant disease or other drug therapy. ADVERSE REACTIONS The safety and efficacy of DITROPAN (oxybutynin chloride) was evaluated in a total of 199 patients in three clinical trials. These participants were treated with DITROPAN 5-20 mg/day for up to 6 weeks. Table 3 shows the incidence of adverse events judged by investigators to be at least possibly related to treatment and reported by at least 5% of patients. 8 Reference ID: 3105471 This label may not be the latest approved by FDA.

The pH of the suspension ranges from 2.2 to 49 3.7. 50 CLINICAL PHARMACOLOGY 51 Pharmacodynamics: Naproxen is a nonsteroidal anti-inflammatory drug (NSAID) with 52 analgesic and antipyretic properties. The sodium salt of naproxen has been developed as a 53 more rapidly absorbed formulation of naproxen for use as an analgesic. The mechanism 54 of action of the naproxen anion, like that of other NSAIDs, is not completely understood 55 but may be related to prostaglandin synthetase inhibition. 56 Pharmacokinetics: Naproxen itself is rapidly and completely absorbed from the 57 gastrointestinal tract with an in vivo bioavailability of 95%. The different dosage forms 58 of NAPROSYN are bioequivalent in terms of extent of absorption (AUC) and peak 59 concentration (Cmax); however, the products do differ in their pattern of absorption. These 60 differences between naproxen products are related to both the chemical form of naproxen 61 used and its formulation. Even with the observed differences in pattern of absorption, the 62 elimination half-life of naproxen is unchanged across products ranging from 12 to 17 63 hours. Steady-state levels of naproxen are reached in 4 to 5 days, and the degree of 64 naproxen accumulation is consistent with this half-life. This suggests that the differences 65 in pattern of release play only a negligible role in the attainment of steady-state plasma 66 levels. 67 Absorption: 68 Immediate Release: After administration of NAPROSYN tablets, peak plasma levels are 69 attained in 2 to 4 hours. After oral administration of ANAPROX, peak plasma levels are 70 attained in 1 to 2 hours. The difference in rates between the two products is due to the 71 increased aqueous solubility of the sodium salt of naproxen used in ANAPROX. Peak 72 plasma levels of naproxen given as NAPROSYN Suspension are attained in 1 to 4 hours. 73 Delayed Release: EC-NAPROSYN is designed with a pH-sensitive coating to provide a 74 barrier to disintegration in the acidic environment of the stomach and to lose integrity in 75 This label may not be the latest approved by FDA.

The enteric polymer coating selected 76 for EC-NAPROSYN dissolves above pH 6. When EC-NAPROSYN was given to fasted 77 subjects, peak plasma levels were attained about 4 to 6 hours following the first dose 78 (range: 2 to 12 hours). An in vivo study in man using radiolabeled EC-NAPROSYN 79 tablets demonstrated that EC-NAPROSYN dissolves primarily in the small intestine 80 rather than the stomach, so the absorption of the drug is delayed until the stomach is 81 emptied. 82 When EC-NAPROSYN and NAPROSYN were given to fasted subjects (n=24) in a 83 crossover study following 1 week of dosing, differences in time to peak plasma levels 84 (Tmax) were observed, but there were no differences in total absorption as measured by 85 Cmax and AUC: 86 EC-NAPROSYN* 500 mg bid NAPROSYN* 500 mg bid Cmax (µg/mL) 94.9 (18%) 97.4 (13%) Tmax (hours) 4 (39%) 1.9 (61%) AUC0–12 hr (µg·hr/mL) 845 (20%) 767 (15%) *Mean value (coefficient of variation) 87 Antacid Effects: When EC-NAPROSYN was given as a single dose with antacid (54 mEq 88 buffering capacity), the peak plasma levels of naproxen were unchanged, but the time to 89 peak was reduced (mean Tmax fasted 5.6 hours, mean Tmax with antacid 5 hours), although 90 not significantly. 91 Food Effects: When EC-NAPROSYN was given as a single dose with food, peak plasma 92 levels in most subjects were achieved in about 12 hours (range: 4 to 24 hours). Residence 93 time in the small intestine until disintegration was independent of food intake. The 94 presence of food prolonged the time the tablets remained in the stomach, time to first 95 detectable serum naproxen levels, and time to maximal naproxen levels (Tmax), but did 96 not affect peak naproxen levels (Cmax). 97 Distribution: 98 Naproxen has a volume of distribution of 0.16 L/kg. At therapeutic levels naproxen is 99 greater than 99% albumin-bound. At doses of naproxen greater than 500 mg/day there is 100 less than proportional increase in plasma levels due to an increase in clearance caused by 101 saturation of plasma protein binding at higher doses (average trough Css 36.5, 49.2 and 102 56.4 mg/L with 500, 1000 and 1500 mg daily doses of naproxen). The naproxen anion 103 has been found in the milk of lactating women at a concentrations equivalent to 104 approximately 1% of maximum naproxen concentration in plasma (see PRECAUTIONS: 105 Nursing Mothers). 106 Metabolism: 107 Naproxen is extensively metabolized to 6-0-desmethyl naproxen, and both parent and 108 metabolites do not induce metabolizing enzymes. 109 This label may not be the latest approved by FDA.

Approximately 95% of the naproxen from 111 any dose is excreted in the urine, primarily as naproxen (less than 1%), 6-0-desmethyl 112 naproxen (less than 1%) or their conjugates (66% to 92%). The plasma half-life of the 113 naproxen anion in humans ranges from 12 to 17 hours. The corresponding half-lives of 114 both naproxen’s metabolites and conjugates are shorter than 12 hours, and their rates of 115 excretion have been found to coincide closely with the rate of naproxen disappearance 116 from the plasma. In patients with renal failure metabolites may accumulate (see 117 PRECAUTIONS: Renal Effects). 118 Special Populations: 119 Pediatric Patients: In pediatric patients aged 5 to 16 years with arthritis, plasma naproxen 120 levels following a 5 mg/kg single dose of naproxen suspension (see DOSAGE AND 121 ADMINISTRATION) were found to be similar to those found in normal adults following 122 a 500 mg dose. The terminal half-life appears to be similar in pediatric and adult patients. 123 Pharmacokinetic studies of naproxen were not performed in pediatric patients younger 124 than 5 years of age. Pharmacokinetic parameters appear to be similar following 125 administration of naproxen suspension or tablets in pediatric patients. EC-NAPROSYN 126 has not been studied in subjects under the age of 18. 127 Geriatric Patients: Studies indicate that although total plasma concentration of naproxen 128 is unchanged, the unbound plasma fraction of naproxen is increased in the elderly, 129 although the unbound fraction is less than 1% of the total naproxen concentration. 130 Unbound trough naproxen concentrations in elderly subjects have been reported to range 131 from 0.12% to 0.19% of total naproxen concentration, compared with 0.05% to 0.075% 132 in younger subjects. The clinical significance of this finding is unclear, although it is 133 possible that the increase in free naproxen concentration could be associated with an 134 increase in the rate of adverse events per a given dosage in some elderly patients. 135 Race: Pharmacokinetic differences due to race have not been studied. 136 Hepatic Insufficiency: Naproxen pharmacokinetics has not been determined in subjects 137 with hepatic insufficiency. 138 Renal Insufficiency: Naproxen pharmacokinetics has not been determined in subjects 139 with renal insufficiency. Given that naproxen, its metabolites and conjugates are 140 primarily excreted by the kidney, the potential exists for naproxen metabolites to 141 accumulate in the presence of renal insufficiency. Elimination of naproxen is decreased 142 in patients with severe renal impairment. Naproxen-containing products are not 143 recommended for use in patients with moderate to severe and severe renal impairment 144 (creatinine < 30 ml/min) (see PRECAUTIONS: Renal Effects). 145 CLINICAL STUDIES 146 General Information: Naproxen has been studied in patients with rheumatoid arthritis, 147 osteoarthritis, juvenile arthritis, ankylosing spondylitis, tendonitis and bursitis, and acute 148 gout. Improvement in patients treated for rheumatoid arthritis was demonstrated by a 149 This label may not be the latest approved by FDA.

Generally, response to 152 naproxen has not been found to be dependent on age, sex, severity or duration of 153 rheumatoid arthritis. 154 In patients with osteoarthritis, the therapeutic action of naproxen has been shown by a 155 reduction in joint pain or tenderness, an increase in range of motion in knee joints, 156 increased mobility as demonstrated by a reduction in walking time, and improvement in 157 capacity to perform activities of daily living impaired by the disease. 158 In a clinical trial comparing standard formulations of naproxen 375 mg bid (750 mg a 159 day) vs 750 mg bid (1500 mg/day), 9 patients in the 750 mg group terminated 160 prematurely because of adverse events. Nineteen patients in the 1500 mg group 161 terminated prematurely because of adverse events. Most of these adverse events were 162 gastrointestinal events. 163 In clinical studies in patients with rheumatoid arthritis, osteoarthritis, and juvenile 164 arthritis, naproxen has been shown to be comparable to aspirin and indomethacin in 165 controlling the aforementioned measures of disease activity, but the frequency and 166 severity of the milder gastrointestinal adverse effects (nausea, dyspepsia, heartburn) and 167 nervous system adverse effects (tinnitus, dizziness, lightheadedness) were less in 168 naproxen-treated patients than in those treated with aspirin or indomethacin. 169 In patients with ankylosing spondylitis, naproxen has been shown to decrease night pain, 170 morning stiffness and pain at rest. In double-blind studies the drug was shown to be as 171 effective as aspirin, but with fewer side effects. 172 In patients with acute gout, a favorable response to naproxen was shown by significant 173 clearing of inflammatory changes (e.g., decrease in swelling, heat) within 24 to 48 hours, 174 as well as by relief of pain and tenderness. 175 Naproxen has been studied in patients with mild to moderate pain secondary to 176 postoperative, orthopedic, postpartum episiotomy and uterine contraction pain and 177 dysmenorrhea. Onset of pain relief can begin within 1 hour in patients taking naproxen 178 and within 30 minutes in patients taking naproxen sodium. Analgesic effect was shown 179 by such measures as reduction of pain intensity scores, increase in pain relief scores, 180 decrease in numbers of patients requiring additional analgesic medication, and delay in 181 time to remedication. The analgesic effect has been found to last for up to 12 hours. 182 Naproxen may be used safely in combination with gold salts and/or corticosteroids; 183 however, in controlled clinical trials, when added to the regimen of patients receiving 184 corticosteroids, it did not appear to cause greater improvement over that seen with 185 corticosteroids alone. Whether naproxen has a “steroid-sparing” effect has not been 186 adequately studied. When added to the regimen of patients receiving gold salts, naproxen 187 did result in greater improvement. Its use in combination with salicylates is not 188 recommended because there is evidence that aspirin increases the rate of excretion of 189 This label may not be the latest approved by FDA.

In addition, as with other 191 NSAIDs, the combination may result in higher frequency of adverse events than 192 demonstrated for either product alone. 193 In 51Cr blood loss and gastroscopy studies with normal volunteers, daily administration of 194 1000 mg of naproxen as 1000 mg of NAPROSYN (naproxen) or 1100 mg of ANAPROX 195 (naproxen sodium) has been demonstrated to cause statistically significantly less gastric 196 bleeding and erosion than 3250 mg of aspirin. 197 Three 6-week, double-blind, multicenter studies with EC-NAPROSYN (naproxen) (375 198 or 500 mg bid, n=385) and NAPROSYN (375 or 500 mg bid, n=279) were conducted 199 comparing EC-NAPROSYN with NAPROSYN, including 355 rheumatoid arthritis and 200 osteoarthritis patients who had a recent history of NSAID-related GI symptoms. These 201 studies indicated that EC-NAPROSYN and NAPROSYN showed no significant 202 differences in efficacy or safety and had similar prevalence of minor GI complaints. 203 Individual patients, however, may find one formulation preferable to the other. 204 Five hundred and fifty-three patients received EC-NAPROSYN during long-term open- 205 label trials (mean length of treatment was 159 days). The rates for clinically-diagnosed 206 peptic ulcers and GI bleeds were similar to what has been historically reported for long- 207 term NSAID use. 208 Geriatric Patients: The hepatic and renal tolerability of long-term naproxen 209 administration was studied in two double blind clinical trials involving 586 patients. Of 210 the patients studied, 98 patients were age 65 and older and 10 of the 98 patients were age 211 75 and older. Naproxen was administered at doses of 375 mg twice daily or 750 mg twice 212 daily for up to 6 months. Transient abnormalities of laboratory tests assessing hepatic and 213 renal function were noted in some patients, although there were no differences noted in 214 the occurrence of abnormal values among different age groups. 215 INDIVIDUALIZATION OF DOSAGE 216 Although NAPROSYN, NAPROSYN Suspension, EC-NAPROSYN, ANAPROX and 217 ANAPROX DS all circulate in the plasma as naproxen, they have pharmacokinetic 218 differences that may affect onset of action. Onset of pain relief can begin within 30 219 minutes in patients taking naproxen sodium and within 1 hour in patients taking 220 naproxen. Because EC-NAPROSYN dissolves in the small intestine rather than in the 221 stomach, the absorption of the drug is delayed compared to the other naproxen 222 formulations (see CLINICAL PHARMACOLOGY). 223 The recommended strategy for initiating therapy is to choose a formulation and a starting 224 dose likely to be effective for the patient and then adjust the dosage based on observation 225 of benefit and/or adverse events. A lower dose should be considered in patients with renal 226 or hepatic impairment or in elderly patients (see PRECAUTIONS). 227 Analgesia/Dysmenorrhea/Bursitis and Tendinitis: Because the sodium salt of naproxen 228 is more rapidly absorbed, ANAPROX/ANAPROX DS is recommended for the 229 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda EC-NAPROSYN® (naproxen delayed-release tablets), NAPROSYN® (naproxen tablets), ANAPROX®/ANAPROX® DS (naproxen sodium tablets), NAPROSYN® (naproxen suspension) 7 management of acute painful conditions when prompt onset of pain relief is desired. The 230 recommended starting dose is 550 mg followed by 550 mg every 12 hours or 275 mg 231 every 6 to 8 hours, as required. The initial total daily dose should not exceed 1375 mg of 232 naproxen sodium. Thereafter, the total daily dose should not exceed 1100 mg of naproxen 233 sodium. NAPROSYN may also be used for treatment of acute pain and dysmenorrhea. 234 EC-NAPROSYN is not recommended for initial treatment of acute pain because 235 absorption of naproxen is delayed compared to other naproxen-containing products (see 236 CLINICAL PHARMACOLOGY and INDICATIONS AND USAGE). 237 Acute Gout: The recommended starting dose is 750 mg of NAPROSYN followed by 250 238 mg every 8 hours until the attack has subsided. ANAPROX may also be used at a starting 239 dose of 825 mg followed by 275 mg every 8 hours as needed. EC-NAPROSYN is not 240 recommended because of the delay in absorption (see CLINICAL PHARMACOLOGY). 241 Osteoarthritis/Rheumatoid Arthritis/Ankylosing Spondylitis: The recommended dose of 242 naproxen is NAPROSYN or NAPROSYN Suspension 250 mg, 375 mg or 500 mg taken 243 twice daily (morning and evening) or EC-NAPROSYN 375 mg or 500 mg taken twice 244 daily. Naproxen sodium may also be used (see DOSAGE AND ADMINISTRATION). 245 During long-term administration the dose of naproxen may be adjusted up or down 246 depending on the clinical response of the patient. A lower daily dose may suffice for 247 long-term administration. In patients who tolerate lower doses well, the dose may be 248 increased to 1500 mg per day for up to 6 months when a higher level of anti- 249 inflammatory/analgesic activity is required. When treating patients with naproxen 1500 250 mg/day (as NAPROSYN or 1650 mg of ANAPROX), the physician should observe 251 sufficient increased clinical benefit to offset the potential increased risk. The morning and 252 evening doses do not have to be equal in size and administration of the drug more 253 frequently than twice daily does not generally make a difference in response (see 254 CLINICAL PHARMACOLOGY). 255 Juvenile Arthritis: The use of NAPROSYN Suspension allows for more flexible dose 256 titration. In pediatric patients, doses of 5 mg/kg/day produced plasma levels of naproxen 257 similar to those seen in adults taking 500 mg of naproxen (see CLINICAL 258 PHARMACOLOGY). 259 The recommended total daily dose is approximately 10 mg/kg given in two divided doses 260 (ie, 5 mg/kg given twice a day) (see DOSAGE AND ADMINISTRATION). 261 INDICATIONS AND USAGE 262 Naproxen as NAPROSYN, EC-NAPROSYN, ANAPROX, ANAPROX DS or 263 NAPROSYN Suspension is indicated: 264 • For the relief of the signs and symptoms of rheumatoid arthritis 265 • For the relief of the signs and symptoms of osteoarthritis 266 • For the relief of the signs and symptoms of ankylosing spondylitis 267 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda EC-NAPROSYN® (naproxen delayed-release tablets), NAPROSYN® (naproxen tablets), ANAPROX®/ANAPROX® DS (naproxen sodium tablets), NAPROSYN® (naproxen suspension) 8 • For the relief of the signs and symptoms of juvenile arthritis 268 Naproxen as NAPROSYN Suspension is recommended for juvenile rheumatoid arthritis 269 in order to obtain the maximum dosage flexibility based on the patient’s weight. 270 Naproxen as NAPROSYN, ANAPROX, ANAPROX DS and NAPROSYN Suspension is 271 also indicated: 272 • For relief of the signs and symptoms of tendinitis 273 • For relief of the signs and symptoms of bursitis 274 • For relief of the signs and symptoms of acute gout 275 • For the management of pain 276 • For the management of primary dysmenorrhea 277 EC-NAPROSYN is not recommended for initial treatment of acute pain because the 278 absorption of naproxen is delayed compared to absorption from other naproxen- 279 containing products (see CLINICAL PHARMACOLOGY and DOSAGE AND 280 ADMINISTRATION). 281 CONTRAINDICATIONS 282 All naproxen products are contraindicated in patients who have had allergic reactions to 283 prescription as well as to over-the-counter products containing naproxen. It is also 284 contraindicated in patients in whom aspirin or other nonsteroidal anti- 285 inflammatory/analgesic drugs induce the syndrome of asthma, rhinitis, and nasal polyps. 286 Both types of reactions have the potential of being fatal. Anaphylactoid reactions to 287 naproxen, whether of the true allergic type or the pharmacologic idiosyncratic (eg, aspirin 288 hypersensitivity syndrome) type, usually but not always occur in patients with a known 289 history of such reactions. Therefore, careful questioning of patients for such things as 290 asthma, nasal polyps, urticaria, and hypotension associated with nonsteroidal anti- 291 inflammatory drugs before starting therapy is important. In addition, if such symptoms 292 occur during therapy, treatment should be discontinued (see WARNINGS: Anaphylactoid 293 Reactions and PRECAUTIONS: Preexisting Asthma). 294 WARNINGS 295 Gastrointestinal (GI) Effects – Risk of GI Ulceration, Bleeding, and Perforation: 296 Serious gastrointestinal toxicity such as bleeding, ulceration and perforation of the 297 stomach, small intestine or large intestine, can occur at any time, with or without warning 298 symptoms, in patients treated with nonsteroidal anti-inflammatory drugs (NSAIDs). 299 Minor upper gastrointestinal problems, such as dyspepsia, are common and may also 300 occur at any time during NSAID therapy. Therefore, physicians and patients should 301 remain alert for ulceration and bleeding, even in the absence of previous GI tract 302 symptoms (see PRECAUTIONS: Hematological Effects). Patients should be informed 303 about the signs and/or symptoms of serious GI toxicity and the steps to take if they occur. 304 This label may not be the latest approved by FDA.

Only 1 in 5 patients who develop a serious upper GI adverse event 306 on NSAID therapy is symptomatic. It has been demonstrated that upper GI ulcers, gross 307 bleeding or perforation, caused by NSAIDs, appear to occur in approximately 1% of 308 patients treated for 3 to 6 months and in about 2% to 4% of patients treated for 1 year. 309 These trends continue, thus increasing the likelihood of developing a serious GI event at 310 some time during the course of therapy. However, even short-term therapy is not without 311 risk. 312 NSAIDs should be prescribed with extreme caution in patients with a prior history of 313 ulcer disease or gastrointestinal bleeding. Most spontaneous reports of fatal GI events are 314 in elderly or debilitated patients and therefore special care should be taken in treating this 315 population. To minimize the potential risk for an adverse GI event, the lowest 316 effective dose should be used for the shortest possible duration. For high-risk patients, 317 alternate therapies that do not involve NSAIDs should be considered. 318 Studies have shown that patients with a prior history of peptic ulcer disease and/or 319 gastrointestinal bleeding and who use NSAIDs, have a greater than 10-fold risk for 320 developing a GI bleed than patients with neither of these risk factors. In addition to a past 321 history of ulcer disease, pharmacoepidemiological studies have identified several other 322 co-therapies or co-morbid conditions that may increase the risk for GI bleeding such as: 323 treatment with oral corticosteroids, treatment with anticoagulants, longer duration of 324 NSAID therapy, smoking, alcoholism, older age, and poor general health status. 325 Anaphylactoid Reactions: As with other NSAIDs, anaphylactoid reactions may occur in 326 patients without known prior exposure to naproxen. Naproxen should not be given to 327 patients with the aspirin triad. This symptom complex typically occurs in asthmatic 328 patients who experience rhinitis with or without nasal polyps, or who exhibit severe, 329 potentially fatal bronchospasm after taking aspirin or other NSAIDs (see 330 CONTRAINDICATIONS and PRECAUTIONS: Preexisting Asthma). Emergency help 331 should be sought in cases where an anaphylactoid reaction occurs. 332 Advanced Renal Disease: In cases with advanced kidney disease, treatment with 333 naproxen is not recommended. If NSAID therapy, however, must be initiated, close 334 monitoring of the patient’s kidney function is advisable (see PRECAUTIONS: Renal 335 Effects). 336 Pregnancy: In late pregnancy, as with other NSAIDs, naproxen should be avoided 337 because it may cause premature closure of the ductus arteriosus. 338 PRECAUTIONS 339 General: NAPROXEN-CONTAINING PRODUCTS SUCH AS NAPROSYN, EC- 340 NAPROSYN, ANAPROX, ANAPROX DS, NAPROSYN SUSPENSION, ALEVE®*, 341 AND OTHER NAPROXEN PRODUCTS SHOULD NOT BE USED 342 CONCOMITANTLY SINCE THEY ALL CIRCULATE IN THE PLASMA AS 343 THE NAPROXEN ANION. 344 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda EC-NAPROSYN® (naproxen delayed-release tablets), NAPROSYN® (naproxen tablets), ANAPROX®/ANAPROX® DS (naproxen sodium tablets), NAPROSYN® (naproxen suspension) 10 Naproxen cannot be expected to substitute for corticosteroids or to treat corticosteroid 345 insufficiency. Abrupt discontinuation of corticosteroids may lead to disease exacerbation. 346 Patients on prolonged corticosteroid therapy should have their therapy tapered slowly if a 347 decision is made to discontinue corticosteroids and the patient should be observed closely 348 for any evidence of adverse effects, including adrenal insufficiency and exacerbation of 349 symptoms of arthritis. 350 Patients with initial hemoglobin values of 10 g or less who are to receive long-term 351 therapy should have hemoglobin values determined periodically. 352 The antipyretic and anti-inflammatory activities of the drug may reduce fever and 353 inflammation, thus diminishing their utility as diagnostic signs in detecting complications 354 of presumed noninfectious, noninflammatory painful conditions. 355 Because of adverse eye findings in animal studies with drugs of this class, it is 356 recommended that ophthalmic studies be carried out if any change or disturbance in 357 vision occurs. 358 Hepatic Effects: As with other nonsteroidal anti-inflammatory drugs, borderline 359 elevations of one or more liver tests may occur in up to 15% of patients. These 360 abnormalities may progress, may remain essentially unchanged, or may be transient with 361 continued therapy. The SGPT (ALT) test is probably the most sensitive indicator of liver 362 dysfunction. Meaningful (3 times the upper limit of normal) elevations of SGPT or 363 SGOT (AST) occurred in controlled clinical trials in less than 1% of patients. A patient 364 with symptoms and/or signs suggesting liver dysfunction or in whom an abnormal liver 365 test has occurred, should be evaluated for evidence of the development of more severe 366 hepatic reaction while on therapy with naproxen. Severe hepatic reactions, including 367 jaundice and cases of fatal hepatitis, have been reported with naproxen as with other 368 nonsteroidal anti-inflammatory drugs. Although such reactions are rare, if abnormal liver 369 tests persist or worsen, if clinical signs and symptoms consistent with liver disease 370 develop, or if systemic manifestations occur (e.g., eosinophilia, rash, etc.), naproxen 371 should be discontinued. 372 Renal Effects: Caution should be used when initiating treatment with naproxen in 373 patients with considerable dehydration. It is advisable to rehydrate patients first and then 374 start therapy with naproxen. Caution is also recommended in patients with pre-existing 375 kidney disease (see WARNINGS: Advanced Renal Disease). 376 As with other nonsteroidal anti-inflammatory drugs, long-term administration of 377 naproxen to animals has resulted in renal papillary necrosis and other abnormal renal 378 pathology. In humans, there have been reports of impaired renal function, renal failure, 379 acute interstitial nephritis, hematuria, proteinuria, renal papillary necrosis, and 380 occasionally nephrotic syndrome associated with naproxen-containing products and other 381 NSAIDs since they have been marketed. 382 A second form of renal toxicity has been seen in patients taking naproxen as well as other 383 nonsteroidal anti-inflammatory drugs. In patients with prerenal conditions leading to a 384 This label may not be the latest approved by FDA.

Patients at greatest risk of this reaction are those with impaired renal function, 389 hypovolemia, heart failure, liver dysfunction, salt depletion, those taking diuretics and 390 ACE inhibitors, and the elderly. Discontinuation of nonsteroidal anti-inflammatory 391 therapy is typically followed by recovery to the pretreatment state. 392 Naproxen and its metabolites are eliminated primarily by the kidneys; therefore, the drug 393 should be used with caution in such patients and the monitoring of serum creatinine 394 and/or creatinine clearance is advised. A reduction in daily dosage should be considered 395 to avoid the possibility of excessive accumulation of naproxen metabolites in these 396 patients. Naproxen-containing products are not recommended for use in patients with 397 moderate to severe and severe renal impairment (creatinine < 30 ml/min). 398 Chronic alcoholic liver disease and probably other diseases with decreased or abnormal 399 plasma proteins (albumin) reduce the total plasma concentration of naproxen, but the 400 plasma concentration of unbound naproxen is increased. Caution is advised when high 401 doses are required and some adjustment of dosage may be required in these patients. It is 402 prudent to use the lowest effective dose. 403 Studies indicate that although total plasma concentration of naproxen is unchanged, the 404 unbound plasma fraction of naproxen is increased in the elderly. Caution is advised when 405 high doses are required and some adjustment of dosage may be required in elderly 406 patients. As with other drugs used in the elderly, it is prudent to use the lowest effective 407 dose. 408 Hematological Effects: Anemia is sometimes seen in patients receiving NSAIDs, 409 including naproxen. This may be due to fluid retention, GI loss, or an incompletely 410 described effect upon erythropoiesis. Patients on long-term treatment with NSAIDs, 411 including naproxen, should have their hemoglobin or hematocrit checked if they exhibit 412 any signs or symptoms of anemia. 413 All drugs which inhibit the biosynthesis of prostaglandins may interfere to some extent 414 with platelet function and vascular responses to bleeding. 415 NSAIDs inhibit platelet aggregation and have been shown to prolong bleeding time in 416 some patients. Unlike aspirin, their effect on platelet function is quantitatively less, of 417 shorter duration, and reversible. Naproxen does not generally affect platelet counts, 418 prothrombin time (PT), or partial thromboplastin time (PTT). Patients receiving naproxen 419 who may be adversely affected by alterations in platelet function, such as those with 420 coagulation disorders or patients receiving anticoagulants, should be carefully monitored. 421 Fluid Retention and Edema: Peripheral edema has been observed in some patients 422 receiving naproxen. Since each ANAPROX or ANAPROX DS tablet contains 25 mg or 423 50 mg of sodium (about 1 mEq per each 250 mg of naproxen), and each teaspoonful of 424 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda EC-NAPROSYN® (naproxen delayed-release tablets), NAPROSYN® (naproxen tablets), ANAPROX®/ANAPROX® DS (naproxen sodium tablets), NAPROSYN® (naproxen suspension) 12 NAPROSYN Suspension contains 39 mg (about 1.5 mEq per each 125 mg of naproxen) 425 of sodium, this should be considered in patients whose overall intake of sodium must be 426 severely restricted. For these reasons, ANAPROX, ANAPROX DS and NAPROSYN 427 Suspension should be used with caution in patients with fluid retention, hypertension or 428 heart failure. 429 Preexisting Asthma: Patients with asthma may have aspirin-sensitive asthma. The use of 430 aspirin in patients with aspirin-sensitive asthma has been associated with severe 431 bronchospasm, which can be fatal. Since cross reactivity, including bronchospasm, 432 between aspirin and other nonsteroidal anti-inflammatory drugs has been reported in such 433 aspirin-sensitive patients, naproxen should not be administered to patients with this form 434 of aspirin sensitivity and should be used with caution in patients with preexisting asthma. 435 Information for Patients: Naproxen, in NAPROSYN, EC-NAPROSYN, ANAPROX, 436 ANAPROX DS and NAPROSYN Suspension can cause discomfort and, rarely, more 437 serious side effects, such as gastrointestinal bleeding, which may result in hospitalization 438 and even fatal outcomes. Although serious GI tract ulcerations and bleeding can occur 439 without warning symptoms, patients should be alert for the signs and symptoms of 440 ulcerations and bleeding, and should ask for medical advice when observing any 441 indicative signs or symptoms. Patients should be apprised of the importance of this 442 follow-up (see WARNINGS: Gastrointestinal (GI) Effects-Risk of GI Ulceration, 443 Bleeding, and Perforation). 444 Patients should promptly report signs or symptoms of gastrointestinal ulceration or 445 bleeding, skin rash, unexplained weight gain or edema to their physicians. 446 Patients should be informed of the warning signs and symptoms of hepatotoxicity (eg, 447 nausea, fatigue, lethargy, pruritus, jaundice, right upper quadrant tenderness, and “flu- 448 like” symptoms). If these occur, patients should be instructed to stop therapy and seek 449 immediate medical therapy. 450 Patients should also be instructed to seek immediate emergency help in the case of an 451 anaphylactoid reaction (see WARNINGS). 452 In late pregnancy, naproxen, in NAPROSYN, EC-NAPROSYN, ANAPROX, 453 ANAPROX DS, and NAPROSYN SUSPENSION, should be avoided because it may 454 cause premature closure of the ductus arteriosus. 455 Caution should be exercised by patients whose activities require alertness if they 456 experience drowsiness, dizziness, vertigo or depression during therapy with naproxen. 457 Laboratory Tests: Because serious GI tract ulcerations and bleeding can occur without 458 warning symptoms, physicians should monitor for signs or symptoms of GI bleeding. If 459 clinical signs and symptoms consistent with liver or renal disease develop, systemic 460 manifestations occur (eg, eosinophilia, rash, etc.) or if abnormal liver tests persist or 461 worsen, naproxen should be discontinued. 462 Drug Interactions: 463 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda EC-NAPROSYN® (naproxen delayed-release tablets), NAPROSYN® (naproxen tablets), ANAPROX®/ANAPROX® DS (naproxen sodium tablets), NAPROSYN® (naproxen suspension) 13 Aspirin: Concomitant administration of naproxen and aspirin is not recommended 464 because naproxen is displaced from its binding sites during the concomitant 465 administration of aspirin, resulting in lower plasma concentrations and peak plasma 466 levels. 467 Methotrexate: Caution should be used if naproxen is administered concomitantly with 468 methotrexate. Naproxen, naproxen sodium and other nonsteroidal anti-inflammatory 469 drugs have been reported to reduce the tubular secretion of methotrexate in an animal 470 model, possibly increasing the toxicity of methotrexate. 471 ACE-inhibitors: Reports suggest that NSAIDs may diminish the antihypertensive effect 472 of ACE-inhibitors. The use of NSAIDs in patients who are receiving ACE inhibitors may 473 potentiate renal disease states (see PRECAUTIONS: Renal Effects). 474 Furosemide: Clinical studies, as well as postmarketing observations, have shown that 475 NSAIDs can reduce the natriuretic effect of furosemide and thiazides in some patients. 476 This response has been attributed to inhibition of renal prostaglandin synthesis. 477 Lithium: Inhibition of renal lithium clearance leading to increases in plasma lithium 478 concentrations has also been reported. The mean minimum lithium concentration 479 increased 15% and the renal clearance was decreased by approximately 20%. These 480 effects have been attributed to inhibition of renal prostaglandin synthesis by the NSAID. 481 Thus, when NSAIDs and lithium are administered concurrently, patients should be 482 observed carefully for signs of lithium toxicity. 483 Warfarin: The effects of warfarin and NSAIDs on GI bleeding are synergistic, such that 484 patients taking both drugs have a risk of serious GI bleeding that is higher than patients 485 taking either drug alone. No significant interactions have been observed in clinical 486 studies with naproxen and coumarin-type anticoagulants. However, caution is advised 487 since interactions have been seen with other nonsteroidal agents of this class. The free 488 fraction of warfarin may increase substantially in some subjects and naproxen interferes 489 with platelet function. 490 Other Information Concerning Drug Interactions: 491 Naproxen is highly bound to plasma albumin; it thus has a theoretical potential for 492 interaction with other albumin-bound drugs such as coumarin-type anticoagulants, 493 sulphonylureas, hydantoins, other NSAIDs, and aspirin. Patients simultaneously 494 receiving naproxen and a hydantoin, sulphonamide or sulphonylurea should be observed 495 for adjustment of dose if required. 496 Naproxen and other nonsteroidal anti-inflammatory drugs can reduce the 497 antihypertensive effect of propranolol and other beta-blockers. 498 Probenecid given concurrently increases naproxen anion plasma levels and extends its 499 plasma half-life significantly. 500 Due to the gastric pH elevating effects of H2-blockers, sucralfate and intensive antacid 501 therapy, concomitant administration of EC-NAPROSYN is not recommended. 502 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda EC-NAPROSYN® (naproxen delayed-release tablets), NAPROSYN® (naproxen tablets), ANAPROX®/ANAPROX® DS (naproxen sodium tablets), NAPROSYN® (naproxen suspension) 14 Drug/Laboratory Test Interactions: Naproxen may decrease platelet aggregation and 503 prolong bleeding time. This effect should be kept in mind when bleeding times are 504 determined. 505 The administration of naproxen may result in increased urinary values for 17-ketogenic 506 steroids because of an interaction between the drug and/or its metabolites with m-di- 507 nitrobenzene used in this assay. Although 17-hydroxy-corticosteroid measurements 508 (Porter-Silber test) do not appear to be artifactually altered, it is suggested that therapy 509 with naproxen be temporarily discontinued 72 hours before adrenal function tests are 510 performed if the Porter-Silber test is to be used. 511 Naproxen may interfere with some urinary assays of 5-hydroxy indoleacetic acid 512 (5HIAA). 513 Carcinogenesis: A 2-year study was performed in rats to evaluate the carcinogenic 514 potential of naproxen at rat doses of 8, 16, and 24 mg/kg/day (50, 100, and 150 mg/m2). 515 The maximum dose used was 0.28 times the systemic exposure to humans at the 516 recommended dose. No evidence of tumorigenicity was found. 517 Pregnancy: Teratogenic Effects: Pregnancy Category C. Reproduction studies have been 518 performed in rats at 20 mg/kg/day (125 mg/m2/day, 0.23 times the human systemic 519 exposure), rabbits at 20 mg/kg/day (220 mg/m2/day, 0.27 times the human systemic 520 exposure), and mice at 170 mg/kg/day (510 mg/m2/day, 0.28 times the human systemic 521 exposure) with no evidence of impaired fertility or harm to the fetus due to the drug. 522 There are no adequate and well-controlled studies in pregnant women. Because animal 523 reproduction studies are not always predictive of human response, naproxen should not 524 be used during pregnancy unless clearly needed. 525 Nonteratogenic Effects: There is some evidence to suggest that when inhibitors of 526 prostaglandin synthesis are used to delay preterm labor there is an increased risk of 527 neonatal complications such as necrotizing enterocolitis, patent ductus arteriosus and 528 intracranial hemorrhage. Naproxen treatment given in late pregnancy to delay parturition 529 has been associated with persistent pulmonary hypertension, renal dysfunction and 530 abnormal prostaglandin E levels in preterm infants. Because of the known effect of drugs 531 of this class on the human fetal cardiovascular system (closure of ductus arteriosus), use 532 during third trimester should be avoided. 533 Labor and Delivery: In rat studies with NSAIDs, as with other drugs known to inhibit 534 prostaglandin synthesis, an increased incidence of dystocia, delayed parturition, and 535 decreased pup survival occurred. Naproxen-containing products are not recommended in 536 labor and delivery because, through its prostaglandin synthesis inhibitory effect, 537 naproxen may adversely affect fetal circulation and inhibit uterine contractions, thus 538 increasing the risk of uterine hemorrhage. 539 Nursing Mothers: The naproxen anion has been found in the milk of lactating women at 540 a concentrations equivalent to approximately 1% of maximum naproxen concentration in 541 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda EC-NAPROSYN® (naproxen delayed-release tablets), NAPROSYN® (naproxen tablets), ANAPROX®/ANAPROX® DS (naproxen sodium tablets), NAPROSYN® (naproxen suspension) 15 plasma. Because of the possible adverse effects of prostaglandin-inhibiting drugs on 542 neonates, use in nursing mothers should be avoided. 543 Pediatric Use: Safety and effectiveness in pediatric patients below the age of 2 years 544 have not been established. Pediatric dosing recommendations for juvenile arthritis are 545 based on well-controlled studies (see DOSAGE AND ADMINISTRATION). There are 546 no adequate effectiveness or dose-response data for other pediatric conditions, but the 547 experience in juvenile arthritis and other use experience have established that single 548 doses of 2.5 to 5 mg/kg (as naproxen suspension, see DOSAGE AND 549 ADMINISTRATION), with total daily dose not exceeding 15 mg/kg/day, are well 550 tolerated in pediatric patients over 2 years of age. 551 Geriatric Use: Studies indicate that although total plasma concentration of naproxen is 552 unchanged, the unbound plasma fraction of naproxen is increased in the elderly. Caution 553 is advised when high doses are required and some adjustment of dosage may be required 554 in elderly patients. As with other drugs used in the elderly, it is prudent to use the lowest 555 effective dose. 556 Experience indicates that geriatric patients may be particularly sensitive to certain 557 adverse effects of nonsteroidal anti-inflammatory drugs. While age does not appear to be 558 an independent risk factor for the development of peptic ulceration and bleeding with 559 naproxen administration, elderly or debilitated patients seem to tolerate peptic ulceration 560 or bleeding less well when these events do occur. Most spontaneous reports of fatal GI 561 events are in the geriatric population (see WARNINGS). 562 Naproxen is known to be substantially excreted by the kidney, and the risk of toxic 563 reactions to this drug may be greater in patients with impaired renal function. Because 564 elderly patients are more likely to have decreased renal function, care should be taken in 565 dose selection, and it may be useful to monitor renal function. Geriatric patients may be 566 at a greater risk for the development of a form of renal toxicity precipitated by reduced 567 prostaglandin formation during administration of nonsteroidal anti-inflammatory drugs 568 (see PRECAUTIONS: Renal Effects). 569 ADVERSE REACTIONS 570 Adverse reactions reported in controlled clinical trials in 960 patients treated for 571 rheumatoid arthritis or osteoarthritis are listed below. In general, reactions in patients 572 treated chronically were reported 2 to 10 times more frequently than they were in short- 573 term studies in the 962 patients treated for mild to moderate pain or for dysmenorrhea. 574 The most frequent complaints reported related to the gastrointestinal tract. 575 A clinical study found gastrointestinal reactions to be more frequent and more severe in 576 rheumatoid arthritis patients taking daily doses of 1500 mg naproxen compared to those 577 taking 750 mg naproxen (see CLINICAL PHARMACOLOGY). 578 In controlled clinical trials with about 80 pediatric patients and in well-monitored, open- 579 label studies with about 400 pediatric patients with juvenile arthritis treated with 580 naproxen, the incidence of rash and prolonged bleeding times were increased, the 581 This label may not be the latest approved by FDA.

Those reactions occurring in less 593 than 3% of the patients are unmarked. 594 In patients taking NSAIDs, the following adverse experiences have also been reported in 595 approximately 1 to 10% of patients. 596 Gastrointestinal (GI) Experiences, including: flatulence, gross bleeding/perforation, GI 597 ulcers (gastric/duodenal), vomiting 598 General: abnormal renal function, anemia, elevated liver enzymes, increased bleeding 599 time, rashes 600 The following are additional adverse experiences reported in <1% of patients taking 601 naproxen during clinical trials and through post-marketing reports. Those adverse 602 reactions observed through post-marketing reports are italicized. 603 Body as a Whole: anaphylactoid reactions, angioneurotic edema, menstrual disorders, 604 pyrexia (chills and fever) 605 Cardiovascular: congestive heart failure, vasculitis 606 Gastrointestinal: gastrointestinal bleeding and/or perforation, hematemesis, jaundice, 607 pancreatitis, vomiting, colitis, abnormal liver function tests, nonpeptic gastrointestinal 608 ulceration, ulcerative stomatitis 609 Hemic and Lymphatic: eosinophilia, leucopenia, melena, thrombocytopenia, 610 agranulocytosis, granulocytopenia, hemolytic anemia, aplastic anemia 611 Metabolic and Nutritional: hyperglycemia, hypoglycemia 612 Nervous System: inability to concentrate, depression, dream abnormalities, insomnia, 613 malaise, myalgia, muscle weakness, aseptic meningitis, cognitive dysfunction 614 This label may not be the latest approved by FDA.

If skin fragility, blistering or other symptoms suggestive of 619 pseudoporphyria occur, treatment should be discontinued and the patient monitored. 620 Special Senses: hearing impairment 621 Urogenital: glomerular nephritis, hematuria, hyperkalemia, interstitial nephritis, 622 nephrotic syndrome, renal disease, renal failure, renal papillary necrosis 623 In patients taking NSAIDs, the following adverse experiences have also been reported in 624 <1% of patients. 625 Body as a Whole: fever, infection, sepsis, anaphylactic reactions, appetite changes, death 626 Cardiovascular: hypertension, tachycardia, syncope, arrhythmia, hypotension, 627 myocardial infarction 628 Gastrointestinal: dry mouth, esophagitis, gastric/peptic ulcers, gastritis, glossitis, 629 hepatitis, eructation, liver failure 630 Hemic and Lymphatic: rectal bleeding, lymphadenopathy, pancytopenia 631 Metabolic and Nutritional: weight changes 632 Nervous System: anxiety, asthenia, confusion, nervousness, paresthesia, somnolence, 633 tremors, convulsions, coma, hallucinations 634 Respiratory: asthma, respiratory depression, pneumonia 635 Dermatologic: exfoliative dermatitis 636 Special Senses: blurred vision, conjunctivitis 637 Urogenital: cystitis, dysuria, oliguria/polyuria, proteinuria 638 OVERDOSAGE 639 Significant naproxen overdosage may be characterized by lethargy, dizziness, 640 drowsiness, epigastric pain, abdominal discomfort, heartburn, indigestion, nausea, 641 transient alterations in liver function, hypoprothrombinemia, renal dysfunction, metabolic 642 acidosis, apnea, disorientation or vomiting. Gastrointestinal bleeding can occur. 643 Hypertension, acute renal failure, respiratory depression, and coma may occur, but are 644 rare. Anaphylactoid reactions have been reported with therapeutic ingestion of NSAIDs, 645 and may occur following an overdose. Because naproxen sodium may be rapidly 646 absorbed, high and early blood levels should be anticipated. A few patients have 647 experienced convulsions, but it is not clear whether or not these were drug-related. It is 648 not known what dose of the drug would be life threatening.

There are no specific antidotes. Hemodialysis does not decrease the plasma 653 concentration of naproxen because of the high degree of its protein binding. Emesis 654 and/or activated charcoal (60 to 100 g in adults, 1 to 2 g/kg in children) and/or osmotic 655 cathartic may be indicated in patients seen within 4 hours of ingestion with symptoms or 656 following a large overdose. Forced diuresis, alkalinization of urine or hemoperfusion may 657 not be useful due to high protein binding. 658 DOSAGE AND ADMINISTRATION 659 Rheumatoid Arthritis, Osteoarthritis and Ankylosing Spondylitis: 660 NAPROSYN 250 mg or 375 mg or 500 mg twice daily twice daily twice daily ANAPROX 275 mg (naproxen 250 mg with 25 mg sodium) twice daily ANAPROX DS 550 mg (naproxen 500 mg with 50 mg sodium) twice daily NAPROSYN Suspension 250 mg (10 mL/2 tsp) or 375 mg (15 mL/3 tsp) or 500 mg (20 mL/4 tsp) twice daily twice daily twice daily EC-NAPROSYN 375 mg or 500 mg twice daily twice daily To maintain the integrity of the enteric coating, the EC-NAPROSYN tablet should not be 661 broken, crushed or chewed during ingestion. 662 During long-term administration, the dose of naproxen may be adjusted up or down 663 depending on the clinical response of the patient. A lower daily dose may suffice for 664 long-term administration. The morning and evening doses do not have to be equal in size 665 and the administration of the drug more frequently than twice daily is not necessary. 666 In patients who tolerate lower doses well, the dose may be increased to naproxen 1500 667 mg per day for limited periods of up to 6 months when a higher level of anti- 668 inflammatory/analgesic activity is required. When treating such patients with naproxen 669 1500 mg/day, the physician should observe sufficient increased clinical benefits to offset 670 the potential increased risk (see CLINICAL PHARMACOLOGY and 671 INDIVIDUALIZATION OF DOSAGE). 672 Geriatric Patients: Studies indicate that although total plasma concentration of naproxen 673 is unchanged, the unbound plasma fraction of naproxen is increased in the elderly. 674 Caution is advised when high doses are required and some adjustment of dosage may be 675 required in elderly patients. As with other drugs used in the elderly, it is prudent to use 676 the lowest effective dose. 677 This label may not be the latest approved by FDA.

A measuring cup marked 679 in 1/2 teaspoon and 2.5 milliliter increments is provided with the NAPROSYN 680 Suspension. The following table may be used as a guide for dosing of NAPROSYN 681 Suspension: 682 Patient’s Weight Dose Administered as 683 13 kg (29 lb) 62.5 mg bid 2.5 mL (1/2 tsp) twice daily 684 25 kg (55 lb) 125 mg bid 5.0 mL (1 tsp) twice daily 685 38 kg (84 lb) 187.5 mg bid 7.5 mL (1 1/2 tsp) twice daily 686 Management of Pain, Primary Dysmenorrhea and Acute Tendonitis and Bursitis: The 687 recommended starting dose is 550 mg of naproxen sodium as ANAPROX/ANAPROX 688 DS followed by 550 mg every 12 hours or 275 mg every 6 to 8 hours as required. The 689 initial total daily dose should not exceed 1375 mg of naproxen sodium. Thereafter, the 690 total daily dose should not exceed 1100 mg of naproxen sodium. NAPROSYN may also 691 be used but EC-NAPROSYN is not recommended for initial treatment of acute pain 692 because absorption of naproxen is delayed compared to other naproxen-containing 693 products (see CLINICAL PHARMACOLOGY, INDICATIONS AND USAGE and 694 INDIVIDUALIZATION OF DOSAGE). 695 Acute Gout: The recommended starting dose is 750 mg of NAPROSYN followed by 250 696 mg every 8 hours until the attack has subsided. ANAPROX may also be used at a starting 697 dose of 825 mg followed by 275 mg every 8 hours. EC-NAPROSYN is not 698 recommended because of the delay in absorption (see CLINICAL PHARMACOLOGY). 699 HOW SUPPLIED 700 NAPROSYN Tablets: 250 mg: round, yellow, biconvex, engraved with NPR LE 250 on 701 one side and scored on the other.

This risk may increase with duration of use. Patients with cardiovascular disease or risk factors for cardiovascular disease may be at greater risk (see WARNINGS). • Naproxen as NAPROSYN, EC-NAPROSYN, ANAPROX, ANAPROX DS or NAPROSYN Suspension is contraindicated for the treatment of peri-operative pain in the setting of coronary artery bypass graft (CABG) surgery (see WARNINGS). Gastrointestinal Risk • NSAIDs cause an increased risk of serious gastrointestinal adverse events including bleeding, ulceration, and perforation of the stomach or intestines, which can be fatal. These events can occur at any time during use and without warning symptoms. Elderly patients are at greater risk for serious gastrointestinal events (see WARNINGS). DESCRIPTION Naproxen is a member of the arylacetic acid group of nonsteroidal anti-inflammatory drugs. The chemical names for naproxen and naproxen sodium are (S)-6-methoxy-α-methyl-2- naphthaleneacetic acid and (S)-6-methoxy-α-methyl-2-naphthaleneacetic acid, sodium salt, respectively. Naproxen and naproxen sodium have the following structures, respectively: Naproxen has a molecular weight of 230.26 and a molecular formula of C14H14O3. Naproxen sodium has a molecular weight of 252.23 and a molecular formula of C14H13NaO3. Naproxen is an odorless, white to off-white crystalline substance. It is lipid-soluble, practically insoluble in water at low pH and freely soluble in water at high pH. The octanol/water partition coefficient of naproxen at pH 7.4 is 1.6 to 1.8. Naproxen sodium is a white to creamy white, crystalline solid, freely soluble in water at neutral pH. This label may not be the latest approved by FDA.

The inactive ingredients are croscarmellose sodium, iron oxides, povidone and magnesium stearate. EC-NAPROSYN (naproxen delayed-release tablets) is available as enteric-coated white tablets containing 375 mg of naproxen and 500 mg of naproxen for oral administration. The inactive ingredients are croscarmellose sodium, povidone and magnesium stearate. The enteric coating dispersion contains methacrylic acid copolymer, talc, triethyl citrate, sodium hydroxide and purified water. The dispersion may also contain simethicone emulsion. The dissolution of this enteric-coated naproxen tablet is pH dependent with rapid dissolution above pH 6. There is no dissolution below pH 4. ANAPROX (naproxen sodium tablets) is available as blue tablets containing 275 mg of naproxen sodium and ANAPROX DS (naproxen sodium tablets) is available as dark blue tablets containing 550 mg of naproxen sodium for oral administration. The inactive ingredients are magnesium stearate, microcrystalline cellulose, povidone and talc. The coating suspension for the ANAPROX 275 mg tablet may contain hydroxypropyl methylcellulose 2910, Opaspray K-1-4210A, polyethylene glycol 8000 or Opadry YS-1-4215. The coating suspension for the ANAPROX DS 550 mg tablet may contain hydroxypropyl methylcellulose 2910, Opaspray K-1-4227, polyethylene glycol 8000 or Opadry YS-1- 4216. NAPROSYN (naproxen suspension) is available as a light orange-colored opaque oral suspension containing 125 mg/5 mL of naproxen in a vehicle containing sucrose, magnesium aluminum silicate, sorbitol solution and sodium chloride (30 mg/5 mL, 1.5 mEq), methylparaben, fumaric acid, FD&C Yellow No. 6, imitation pineapple flavor, imitation orange flavor and purified water. The pH of the suspension ranges from 2.2 to 3.7. CLINICAL PHARMACOLOGY Pharmacodynamics Naproxen is a nonsteroidal anti-inflammatory drug (NSAID) with analgesic and antipyretic properties. The sodium salt of naproxen has been developed as a more rapidly absorbed formulation of naproxen for use as an analgesic. The mechanism of action of the naproxen anion, like that of other NSAIDs, is not completely understood but may be related to prostaglandin synthetase inhibition. Pharmacokinetics Naproxen itself is rapidly and completely absorbed from the gastrointestinal tract with an in vivo bioavailability of 95%. The different dosage forms of NAPROSYN are bioequivalent in terms of extent of absorption (AUC) and peak concentration (Cmax); however, the products do differ in their pattern of absorption. These differences between naproxen products are related to both the chemical form of naproxen used and its formulation. Even with the observed differences in pattern of absorption, the elimination half-life of naproxen is unchanged across products ranging from 12 to 17 hours. Steady-state levels of naproxen are reached in 4 to 5 days, and the degree of naproxen accumulation is consistent with this half-life. This suggests that the differences in pattern of release play only a negligible role in the attainment of steady-state plasma levels. This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda NDA 17-581/S-106, 18-164/S-056, 18-965/S-014, 20-067/S-011 Page 5 Absorption Immediate Release After administration of NAPROSYN tablets, peak plasma levels are attained in 2 to 4 hours. After oral administration of ANAPROX, peak plasma levels are attained in 1 to 2 hours. The difference in rates between the two products is due to the increased aqueous solubility of the sodium salt of naproxen used in ANAPROX. Peak plasma levels of naproxen given as NAPROSYN Suspension are attained in 1 to 4 hours. Delayed Release EC-NAPROSYN is designed with a pH-sensitive coating to provide a barrier to disintegration in the acidic environment of the stomach and to lose integrity in the more neutral environment of the small intestine. The enteric polymer coating selected for EC-NAPROSYN dissolves above pH 6. When EC- NAPROSYN was given to fasted subjects, peak plasma levels were attained about 4 to 6 hours following the first dose (range: 2 to 12 hours). An in vivo study in man using radiolabeled EC- NAPROSYN tablets demonstrated that EC-NAPROSYN dissolves primarily in the small intestine rather than in the stomach, so the absorption of the drug is delayed until the stomach is emptied. When EC-NAPROSYN and NAPROSYN were given to fasted subjects (n=24) in a crossover study following 1 week of dosing, differences in time to peak plasma levels (Tmax) were observed, but there were no differences in total absorption as measured by Cmax and AUC: EC-NAPROSYN* 500 mg bid NAPROSYN* 500 mg bid Cmax (µg/mL) 94.9 (18%) 97.4 (13%) Tmax (hours) 4 (39%) 1.9 (61%) AUC0–12 hr (µg·hr/mL) 845 (20%) 767 (15%) *Mean value (coefficient of variation) Antacid Effects When EC-NAPROSYN was given as a single dose with antacid (54 mEq buffering capacity), the peak plasma levels of naproxen were unchanged, but the time to peak was reduced (mean Tmax fasted 5.6 hours, mean Tmax with antacid 5 hours), although not significantly. Food Effects When EC-NAPROSYN was given as a single dose with food, peak plasma levels in most subjects were achieved in about 12 hours (range: 4 to 24 hours). Residence time in the small intestine until disintegration was independent of food intake. The presence of food prolonged the time the tablets remained in the stomach, time to first detectable serum naproxen levels, and time to maximal naproxen levels (Tmax), but did not affect peak naproxen levels (Cmax). Distribution Naproxen has a volume of distribution of 0.16 L/kg. At therapeutic levels naproxen is greater than 99% albumin-bound. At doses of naproxen greater than 500 mg/day there is less than proportional increase in plasma levels due to an increase in clearance caused by saturation of plasma protein binding at higher doses (average trough Css 36.5, 49.2 and 56.4 mg/L with 500, 1000 and 1500 mg daily doses of naproxen, respectively). The naproxen anion has been found in the milk of lactating women at a This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda NDA 17-581/S-106, 18-164/S-056, 18-965/S-014, 20-067/S-011 Page 6 concentration equivalent to approximately 1% of maximum naproxen concentration in plasma (see PRECAUTIONS, Nursing Mothers). Metabolism Naproxen is extensively metabolized to 6-0-desmethyl naproxen, and both parent and metabolites do not induce metabolizing enzymes. Excretion The clearance of naproxen is 0.13 mL/min/kg. Approximately 95% of the naproxen from any dose is excreted in the urine, primarily as naproxen (<1%), 6-0-desmethyl naproxen (<1%) or their conjugates (66% to 92%). The plasma half-life of the naproxen anion in humans ranges from 12 to 17 hours. The corresponding half-lives of both naproxen’s metabolites and conjugates are shorter than 12 hours, and their rates of excretion have been found to coincide closely with the rate of naproxen disappearance from the plasma. In patients with renal failure metabolites may accumulate (see WARNINGS, Renal Effects). Special Populations Pediatric Patients In pediatric patients aged 5 to 16 years with arthritis, plasma naproxen levels following a 5 mg/kg single dose of naproxen suspension (see DOSAGE AND ADMINISTRATION) were found to be similar to those found in normal adults following a 500 mg dose. The terminal half-life appears to be similar in pediatric and adult patients. Pharmacokinetic studies of naproxen were not performed in pediatric patients younger than 5 years of age. Pharmacokinetic parameters appear to be similar following administration of naproxen suspension or tablets in pediatric patients. EC-NAPROSYN has not been studied in subjects under the age of 18. Geriatric Patients Studies indicate that although total plasma concentration of naproxen is unchanged, the unbound plasma fraction of naproxen is increased in the elderly, although the unbound fraction is < 1% of the total naproxen concentration. Unbound trough naproxen concentrations in elderly subjects have been reported to range from 0.12% to 0.19% of total naproxen concentration, compared with 0.05% to 0.075% in younger subjects. The clinical significance of this finding is unclear, although it is possible that the increase in free naproxen concentration could be associated with an increase in the rate of adverse events per a given dosage in some elderly patients. Race Pharmacokinetic differences due to race have not been studied. Hepatic Insufficiency Naproxen pharmacokinetics has not been determined in subjects with hepatic insufficiency. Renal Insufficiency Naproxen pharmacokinetics has not been determined in subjects with renal insufficiency. Given that naproxen, its metabolites and conjugates are primarily excreted by the kidney, the potential exists for naproxen metabolites to accumulate in the presence of renal insufficiency. Elimination of naproxen is decreased in patients with severe renal impairment. Naproxen-containing products are not This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda NDA 17-581/S-106, 18-164/S-056, 18-965/S-014, 20-067/S-011 Page 7 recommended for use in patients with moderate to severe and severe renal impairment (creatinine clearance <30 mL/min) (see WARNINGS, Renal Effects). CLINICAL STUDIES General Information Naproxen has been studied in patients with rheumatoid arthritis, osteoarthritis, juvenile arthritis, ankylosing spondylitis, tendonitis and bursitis, and acute gout. Improvement in patients treated for rheumatoid arthritis was demonstrated by a reduction in joint swelling, a reduction in duration of morning stiffness, a reduction in disease activity as assessed by both the investigator and patient, and by increased mobility as demonstrated by a reduction in walking time. Generally, response to naproxen has not been found to be dependent on age, sex, severity or duration of rheumatoid arthritis. In patients with osteoarthritis, the therapeutic action of naproxen has been shown by a reduction in joint pain or tenderness, an increase in range of motion in knee joints, increased mobility as demonstrated by a reduction in walking time, and improvement in capacity to perform activities of daily living impaired by the disease. In a clinical trial comparing standard formulations of naproxen 375 mg bid (750 mg a day) vs 750 mg bid (1500 mg/day), 9 patients in the 750 mg group terminated prematurely because of adverse events. Nineteen patients in the 1500 mg group terminated prematurely because of adverse events. Most of these adverse events were gastrointestinal events. In clinical studies in patients with rheumatoid arthritis, osteoarthritis, and juvenile arthritis, naproxen has been shown to be comparable to aspirin and indomethacin in controlling the aforementioned measures of disease activity, but the frequency and severity of the milder gastrointestinal adverse effects (nausea, dyspepsia, heartburn) and nervous system adverse effects (tinnitus, dizziness, lightheadedness) were less in naproxen-treated patients than in those treated with aspirin or indomethacin. In patients with ankylosing spondylitis, naproxen has been shown to decrease night pain, morning stiffness and pain at rest. In double-blind studies the drug was shown to be as effective as aspirin, but with fewer side effects. In patients with acute gout, a favorable response to naproxen was shown by significant clearing of inflammatory changes (eg, decrease in swelling, heat) within 24 to 48 hours, as well as by relief of pain and tenderness. Naproxen has been studied in patients with mild to moderate pain secondary to postoperative, orthopedic, postpartum episiotomy and uterine contraction pain and dysmenorrhea. Onset of pain relief can begin within 1 hour in patients taking naproxen and within 30 minutes in patients taking naproxen sodium. Analgesic effect was shown by such measures as reduction of pain intensity scores, increase in pain relief scores, decrease in numbers of patients requiring additional analgesic medication, and delay in time to remedication. The analgesic effect has been found to last for up to 12 hours. Naproxen may be used safely in combination with gold salts and/or corticosteroids; however, in controlled clinical trials, when added to the regimen of patients receiving corticosteroids, it did not appear to cause greater improvement over that seen with corticosteroids alone. Whether naproxen has a “steroid-sparing” effect has not been adequately studied. When added to the regimen of patients receiving gold salts, naproxen did result in greater improvement. Its use in combination with salicylates is not recommended because there is evidence that aspirin increases the rate of excretion of This label may not be the latest approved by FDA.

In addition, as with other NSAIDs, the combination may result in higher frequency of adverse events than demonstrated for either product alone. In 51Cr blood loss and gastroscopy studies with normal volunteers, daily administration of 1000 mg of naproxen as 1000 mg of NAPROSYN (naproxen) or 1100 mg of ANAPROX (naproxen sodium) has been demonstrated to cause statistically significantly less gastric bleeding and erosion than 3250 mg of aspirin. Three 6-week, double-blind, multicenter studies with EC-NAPROSYN (naproxen) (375 or 500 mg bid, n=385) and NAPROSYN (375 or 500 mg bid, n=279) were conducted comparing EC-NAPROSYN with NAPROSYN, including 355 rheumatoid arthritis and osteoarthritis patients who had a recent history of NSAID-related GI symptoms. These studies indicated that EC-NAPROSYN and NAPROSYN showed no significant differences in efficacy or safety and had similar prevalence of minor GI complaints. Individual patients, however, may find one formulation preferable to the other. Five hundred and fifty-three patients received EC-NAPROSYN during long-term open-label trials (mean length of treatment was 159 days). The rates for clinically-diagnosed peptic ulcers and GI bleeds were similar to what has been historically reported for long-term NSAID use. Geriatric Patients The hepatic and renal tolerability of long-term naproxen administration was studied in two double- blind clinical trials involving 586 patients. Of the patients studied, 98 patients were age 65 and older and 10 of the 98 patients were age 75 and older. Naproxen was administered at doses of 375 mg twice daily or 750 mg twice daily for up to 6 months. Transient abnormalities of laboratory tests assessing hepatic and renal function were noted in some patients, although there were no differences noted in the occurrence of abnormal values among different age groups. INDICATIONS AND USAGE Carefully consider the potential benefits and risks of NAPROSYN, EC-NAPROSYN, ANAPROX, ANAPROX DS or NAPROSYN Suspension and other treatment options before deciding to use NAPROSYN, EC-NAPROSYN, ANAPROX, ANAPROX DS or NAPROSYN Suspension. Use the lowest effective dose for the shortest duration consistent with individual patient treatment goals (see WARNINGS). Naproxen as NAPROSYN, EC-NAPROSYN, ANAPROX, ANAPROX DS or NAPROSYN Suspension is indicated: • For the relief of the signs and symptoms of rheumatoid arthritis • For the relief of the signs and symptoms of osteoarthritis • For the relief of the signs and symptoms of ankylosing spondylitis • For the relief of the signs and symptoms of juvenile arthritis Naproxen as NAPROSYN Suspension is recommended for juvenile rheumatoid arthritis in order to obtain the maximum dosage flexibility based on the patient’s weight. This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda NDA 17-581/S-106, 18-164/S-056, 18-965/S-014, 20-067/S-011 Page 9 Naproxen as NAPROSYN, ANAPROX, ANAPROX DS and NAPROSYN Suspension is also indicated: • For relief of the signs and symptoms of tendonitis • For relief of the signs and symptoms of bursitis • For relief of the signs and symptoms of acute gout • For the management of pain • For the management of primary dysmenorrhea EC-NAPROSYN is not recommended for initial treatment of acute pain because the absorption of naproxen is delayed compared to absorption from other naproxen-containing products (see CLINICAL PHARMACOLOGY and DOSAGE AND ADMINISTRATION). CONTRAINDICATIONS NAPROSYN, EC-NAPROSYN, ANAPROX, ANAPROX DS and NAPROSYN Suspension are contraindicated in patients with known hypersensitivity to naproxen and naproxen sodium. NAPROSYN, EC-NAPROSYN, ANAPROX, ANAPROX DS and NAPROSYN Suspension should not be given to patients who have experienced asthma, urticaria, or allergic-type reactions after taking aspirin or other NSAIDs. Severe, rarely fatal, anaphylactic-like reactions to NSAIDs have been reported in such patients (see WARNINGS, Anaphylactoid Reactions and PRECAUTIONS, Preexisting Asthma). NAPROSYN, EC-NAPROSYN, ANAPROX, ANAPROX DS and NAPROSYN Suspension are contraindicated for the treatment of peri-operative pain in the setting of coronary artery bypass graft (CABG) surgery (see WARNINGS). WARNINGS CARDIOVASCULAR EFFECTS Cardiovascular Thrombotic Events Clinical trials of several COX-2 selective and nonselective NSAIDs of up to three years duration have shown an increased risk of serious cardiovascular (CV) thrombotic events, myocardial infarction, and stroke, which can be fatal. All NSAIDS, both COX-2 selective and nonselective, may have a similar risk. Patients with known CV disease or risk factors for CV disease may be at greater risk. To minimize the potential risk for an adverse CV event in patients treated with an NSAID, the lowest effective dose should be used for the shortest duration possible. Physicians and patients should remain alert for the development of such events, even in the absence of previous CV symptoms. Patients should be informed about the signs and/or symptoms of serious CV events and the steps to take if they occur. There is no consistent evidence that concurrent use of aspirin mitigates the increased risk of serious CV thrombotic events associated with NSAID use. The concurrent use of aspirin and an NSAID does increase the risk of serious GI events (see GI WARNINGS). Two large, controlled, clinical trials of a COX-2 selective NSAID for the treatment of pain in the first 10-14 days following CABG surgery found an increased incidence of myocardial infarction and stroke (see CONTRAINDICATIONS). This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda NDA 17-581/S-106, 18-164/S-056, 18-965/S-014, 20-067/S-011 Page 10 Hypertension NSAIDs, including NAPROSYN, EC-NAPROSYN, ANAPROX, ANAPROX DS and NAPROSYN Suspension, can lead to onset of new hypertension or worsening of pre-existing hypertension, either of which may contribute to the increased incidence of CV events. Patients taking thiazides or loop diuretics may have impaired response to these therapies when taking NSAIDs. NSAIDs, including NAPROSYN, EC-NAPROSYN, ANAPROX, ANAPROX DS and NAPROSYN Suspension, should be used with caution in patients with hypertension. Blood pressure (BP) should be monitored closely during the initiation of NSAID treatment and throughout the course of therapy. Congestive Heart Failure and Edema Fluid retention, edema, and peripheral edema have been observed in some patients taking NSAIDs. NAPROSYN, EC-NAPROSYN, ANAPROX, ANAPROX DS and NAPROSYN Suspension should be used with caution in patients with fluid retention, hypertension, or heart failure. Since each ANAPROX or ANAPROX DS tablet contains 25 mg or 50 mg of sodium (about 1 mEq per each 250 mg of naproxen), and each teaspoonful of NAPROSYN Suspension contains 39 mg (about 1.5 mEq per each 125 mg of naproxen) of sodium, this should be considered in patients whose overall intake of sodium must be severely restricted. Gastrointestinal Effects – Risk of Ulceration, Bleeding, and Perforation NSAIDs, including NAPROSYN, EC-NAPROSYN, ANAPROX, ANAPROX DS and NAPROSYN Suspension, can cause serious gastrointestinal (GI) adverse events including inflammation, bleeding, ulceration, and perforation of the stomach, small intestine, or large intestine, which can be fatal. These serious adverse events can occur at any time, with or without warning symptoms, in patients treated with NSAIDs. Only one in five patients, who develop a serious upper GI adverse event on NSAID therapy, is symptomatic. Upper GI ulcers, gross bleeding, or perforation caused by NSAIDs occur in approximately 1% of patients treated for 3-6 months, and in about 2-4% of patients treated for one year. These trends continue with longer duration of use, increasing the likelihood of developing a serious GI event at some time during the course of therapy. However, even short-term therapy is not without risk. The utility of periodic laboratory monitoring has not been demonstrated, nor has it been adequately assessed. Only 1 in 5 patients who develop a serious upper GI adverse event on NSAID therapy is symptomatic. NSAIDs should be prescribed with extreme caution in those with a prior history of ulcer disease or gastrointestinal bleeding. Patients with a prior history of peptic ulcer disease and/or gastrointestinal bleeding who use NSAIDs have a greater than 10-fold increased risk for developing a GI bleed compared to patients with neither of these risk factors. Other factors that increase the risk for GI bleeding in patients treated with NSAIDs include concomitant use of oral corticosteroids or anticoagulants, longer duration of NSAID therapy, smoking, use of alcohol, older age, and poor general health status. Most spontaneous reports of fatal GI events are in elderly or debilitated patients and therefore, special care should be taken in treating this population. To minimize the potential risk for an adverse GI event in patients treated with an NSAID, the lowest effective dose should be used for the shortest possible duration. Patients and physicians should remain alert for signs and symptoms of GI ulceration and bleeding during NSAID therapy and promptly initiate additional evaluation and treatment if a serious GI adverse event is suspected. This should include discontinuation of the NSAID until a serious GI adverse event is ruled out. For high risk patients, alternate therapies that do not involve NSAIDs should be considered.

Renal toxicity has also been seen in patients in whom renal prostaglandins have a compensatory role in the maintenance of renal perfusion. In these patients, administration of a nonsteroidal anti-inflammatory drug may cause a dose-dependent reduction in prostaglandin formation and, secondarily, in renal blood flow, which may precipitate overt renal decompensation. Patients at greatest risk of this reaction are those with impaired renal function, hypovolemia, heart failure, liver dysfunction, salt depletion, those taking diuretics and ACE inhibitors, and the elderly. Discontinuation of nonsteroidal anti-inflammatory drug therapy is usually followed by recovery to the pretreatment state (see WARNINGS, Advanced Renal Disease). Advanced Renal Disease No information is available from controlled clinical studies regarding the use of NAPROSYN, EC- NAPROSYN, ANAPROX, ANAPROX DS or NAPROSYN Suspension in patients with advanced renal disease. Therefore, treatment with NAPROSYN, EC-NAPROSYN, ANAPROX, ANAPROX DS and NAPROSYN Suspension is not recommended in these patients with advanced renal disease. If NAPROSYN, EC-NAPROSYN, ANAPROX, ANAPROX DS or NAPROSYN Suspension therapy must be initiated, close monitoring of the patient's renal function is advisable. Anaphylactoid Reactions As with other NSAIDs, anaphylactoid reactions may occur in patients without known prior exposure to either NAPROSYN, EC-NAPROSYN, ANAPROX, ANAPROX DS or NAPROSYN Suspension. NAPROSYN, EC-NAPROSYN, ANAPROX, ANAPROX DS and NAPROSYN Suspension should not be given to patients with the aspirin triad. This symptom complex typically occurs in asthmatic patients who experience rhinitis with or without nasal polyps, or who exhibit severe, potentially fatal bronchospasm after taking aspirin or other NSAIDs (see CONTRAINDICATIONS and PRECAUTIONS, Preexisting Asthma). Emergency help should be sought in cases where an anaphylactoid reaction occurs. Skin Reactions NSAIDs, including NAPROSYN, EC-NAPROSYN, ANAPROX, ANAPROX DS and NAPROSYN Suspension, can cause serious skin adverse events such as exfoliative dermatitis, Stevens-Johnson Syndrome (SJS), and toxic epidermal necrolysis (TEN), which can be fatal. These serious events may occur without warning. Patients should be informed about the signs and symptoms of serious skin manifestations and use of the drug should be discontinued at the first appearance of skin rash or any other sign of hypersensitivity. Pregnancy In late pregnancy, as with other NSAIDs, NAPROSYN, EC-NAPROSYN, ANAPROX, ANAPROX DS and NAPROSYN Suspension should be avoided because it may cause premature closure of the ductus arteriosus.

NAPROSYN, EC-NAPROSYN, ANAPROX, ANAPROX DS and NAPROSYN Suspension cannot be expected to substitute for corticosteroids or to treat corticosteroid insufficiency. Abrupt discontinuation of corticosteroids may lead to disease exacerbation. Patients on prolonged corticosteroid therapy should have their therapy tapered slowly if a decision is made to discontinue corticosteroids and the patient should be observed closely for any evidence of adverse effects, including adrenal insufficiency and exacerbation of symptoms of arthritis. Patients with initial hemoglobin values of 10 g or less who are to receive long-term therapy should have hemoglobin values determined periodically. The pharmacological activity of NAPROSYN, EC-NAPROSYN, ANAPROX, ANAPROX DS and NAPROSYN Suspension in reducing fever and inflammation may diminish the utility of these diagnostic signs in detecting complications of presumed noninfectious, noninflammatory painful conditions. Because of adverse eye findings in animal studies with drugs of this class, it is recommended that ophthalmic studies be carried out if any change or disturbance in vision occurs. Hepatic Effects Borderline elevations of one or more liver tests may occur in up to 15% of patients taking NSAIDs including NAPROSYN, EC-NAPROSYN, ANAPROX, ANAPROX DS and NAPROSYN Suspension. These laboratory abnormalities may progress, may remain essentially unchanged, or may be transient with continued therapy. The SGPT (ALT) test is probably the most sensitive indicator of liver dysfunction. Notable elevations of ALT or AST (approximately three or more times the upper limit of normal) have been reported in approximately 1% of patients in clinical trials with NSAIDs. In addition, rare cases of severe hepatic reactions, including jaundice and fatal fulminant hepatitis, liver necrosis and hepatic failure, some of them with fatal outcomes have been reported. A patient with symptoms and/or signs suggesting liver dysfunction, or in whom an abnormal liver test has occurred, should be evaluated for evidence of the development of more severe hepatic reaction while on therapy with NAPROSYN, EC-NAPROSYN, ANAPROX, ANAPROX DS or NAPROSYN Suspension. If clinical signs and symptoms consistent with liver disease develop, or if systemic manifestations occur (eg, eosinophilia, rash, etc.), NAPROSYN, EC-NAPROSYN, ANAPROX, ANAPROX DS or NAPROSYN Suspension should be discontinued. Chronic alcoholic liver disease and probably other diseases with decreased or abnormal plasma proteins (albumin) reduce the total plasma concentration of naproxen, but the plasma concentration of unbound naproxen is increased. Caution is advised when high doses are required and some adjustment of dosage may be required in these patients. It is prudent to use the lowest effective dose. This label may not be the latest approved by FDA.

This may be due to fluid retention, occult or gross GI blood loss, or an incompletely described effect upon erythropoiesis. Patients on long-term treatment with NSAIDs, including NAPROSYN, EC-NAPROSYN, ANAPROX, ANAPROX DS and NAPROSYN Suspension, should have their hemoglobin or hematocrit checked if they exhibit any signs or symptoms of anemia. NSAIDs inhibit platelet aggregation and have been shown to prolong bleeding time in some patients. Unlike aspirin, their effect on platelet function is quantitatively less, of shorter duration, and reversible. Patients receiving either NAPROSYN, EC-NAPROSYN, ANAPROX, ANAPROX DS or NAPROSYN Suspension who may be adversely affected by alterations in platelet function, such as those with coagulation disorders or patients receiving anticoagulants, should be carefully monitored. Preexisting Asthma Patients with asthma may have aspirin-sensitive asthma. The use of aspirin in patients with aspirin- sensitive asthma has been associated with severe bronchospasm, which can be fatal. Since cross reactivity, including bronchospasm, between aspirin and other nonsteroidal anti-inflammatory drugs has been reported in such aspirin-sensitive patients, NAPROSYN, EC-NAPROSYN, ANAPROX, ANAPROX DS and NAPROSYN Suspension should not be administered to patients with this form of aspirin sensitivity and should be used with caution in patients with preexisting asthma. Information for Patients Patients should be informed of the following information before initiating therapy with an NSAID and periodically during the course of ongoing therapy. Patients should also be encouraged to read the NSAID Medication Guide that accompanies each prescription dispensed. 1. NAPROSYN, EC-NAPROSYN, ANAPROX, ANAPROX DS and NAPROSYN Suspension, like other NSAIDs, may cause serious CV side effects, such as MI or stroke, which may result in hospitalization and even death. Although serious CV events can occur without warning symptoms, patients should be alert for the signs and symptoms of chest pain, shortness of breath, weakness, slurring of speech, and should ask for medical advice when observing any indicative sign or symptoms. Patients should be apprised of the importance of this follow-up (see WARNINGS, Cardiovascular Effects). 2. NAPROSYN, EC-NAPROSYN, ANAPROX, ANAPROX DS and NAPROSYN Suspension, like other NSAIDs, can cause GI discomfort and, rarely, serious GI side effects, such as ulcers and bleeding, which may result in hospitalization and even death. Although serious GI tract ulcerations and bleeding can occur without warning symptoms, patients should be alert for the signs and symptoms of ulcerations and bleeding, and should ask for medical advice when observing any indicative sign or symptoms including epigastric pain, dyspepsia, melena, and hematemesis. Patients should be apprised of the importance of this follow-up (see WARNINGS, Gastrointestinal Effects-Risk of Ulceration, Bleeding, and Perforation). 3. NAPROSYN, EC-NAPROSYN, ANAPROX, ANAPROX DS and NAPROSYN Suspension, like other NSAIDs, can cause serious skin side effects such as exfoliative dermatitis, SJS, and TEN, which may result in hospitalizations and even death. Although serious skin reactions may occur without warning, patients should be alert for the signs and symptoms of skin rash and blisters, fever, or other signs of hypersensitivity such as itching, and should ask for medical advice when This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda NDA 17-581/S-106, 18-164/S-056, 18-965/S-014, 20-067/S-011 Page 14 observing any indicative signs or symptoms. Patients should be advised to stop the drug immediately if they develop any type of rash and contact their physicians as soon as possible. 4. Patients should promptly report signs or symptoms of unexplained weight gain or edema to their physicians. 5. Patients should be informed of the warning signs and symptoms of hepatotoxicity (eg, nausea, fatigue, lethargy, pruritus, jaundice, right upper quadrant tenderness, and “flu-like” symptoms). If these occur, patients should be instructed to stop therapy and seek immediate medical therapy. 6. Patients should be informed of the signs of an anaphylactoid reaction (eg, difficulty breathing, swelling of the face or throat). If these occur, patients should be instructed to seek immediate emergency help (see WARNINGS). 7. In late pregnancy, as with other NSAIDs, NAPROSYN, EC-NAPROSYN, ANAPROX, ANAPROX DS and NAPROSYN Suspension should be avoided because it may cause premature closure of the ductus arteriosus. 8. Caution should be exercised by patients whose activities require alertness if they experience drowsiness, dizziness, vertigo or depression during therapy with naproxen. Laboratory Tests Because serious GI tract ulcerations and bleeding can occur without warning symptoms, physicians should monitor for signs or symptoms of GI bleeding. Patients on long-term treatment with NSAIDs should have their CBC and a chemistry profile checked periodically. If clinical signs and symptoms consistent with liver or renal disease develop, systemic manifestations occur (eg, eosinophilia, rash, etc.) or if abnormal liver tests persist or worsen, NAPROSYN, EC-NAPROSYN, ANAPROX, ANAPROX DS and NAPROSYN Suspension should be discontinued. Drug Interactions ACE-inhibitors Reports suggest that NSAIDs may diminish the antihypertensive effect of ACE-inhibitors. This interaction should be given consideration in patients taking NSAIDs concomitantly with ACE- inhibitors. Aspirin When naproxen as NAPROSYN, EC-NAPROSYN, ANAPROX, ANAPROX DS or NAPROSYN Suspension is administered with aspirin, its protein binding is reduced, although the clearance of free NAPROSYN, EC-NAPROSYN, ANAPROX, ANAPROX DS or NAPROSYN Suspension is not altered. The clinical significance of this interaction is not known; however, as with other NSAIDs, concomitant administration of naproxen and naproxen sodium and aspirin is not generally recommended because of the potential of increased adverse effects. Diuretics Clinical studies, as well as postmarketing observations, have shown that NAPROSYN, EC- NAPROSYN, ANAPROX, ANAPROX DS and NAPROSYN Suspension can reduce the natriuretic effect-of furosemide and thiazides in some patients. This response has been attributed to inhibition of renal prostaglandin synthesis. During concomitant therapy with NSAIDs, the patient should be observed closely for signs of renal failure (see WARNINGS: Renal Effects), as well as to assure diuretic efficacy. This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda NDA 17-581/S-106, 18-164/S-056, 18-965/S-014, 20-067/S-011 Page 15 Lithium NSAIDs have produced an elevation of plasma lithium levels and a reduction in renal lithium clearance. The mean minimum lithium concentration increased 15% and the renal clearance was decreased by approximately 20%. These effects have been attributed to inhibition of renal prostaglandin synthesis by the NSAID. Thus, when NSAIDs and lithium are administered concurrently, subjects should be observed carefully for signs of lithium toxicity. Methotrexate NSAIDs have been reported to competitively inhibit methotrexate accumulation in rabbit kidney slices. Naproxen, naproxen sodium and other nonsteroidal anti-inflammatory drugs have been reported to reduce the tubular secretion of methotrexate in an animal model. This may indicate that they could enhance the toxicity of methotrexate. Caution should be used when NSAIDs are administered concomitantly with methotrexate. Warfarin The effects of warfarin and NSAIDs on GI bleeding are synergistic, such that users of both drugs together have a risk of serious GI bleeding higher than users of either drug alone. No significant interactions have been observed in clinical studies with naproxen and coumarin-type anticoagulants. However, caution is advised since interactions have been seen with other nonsteroidal agents of this class. The free fraction of warfarin may increase substantially in some subjects and naproxen interferes with platelet function. Other Information Concerning Drug Interactions Naproxen is highly bound to plasma albumin; it thus has a theoretical potential for interaction with other albumin-bound drugs such as coumarin-type anticoagulants, sulphonylureas, hydantoins, other NSAIDs, and aspirin. Patients simultaneously receiving naproxen and a hydantoin, sulphonamide or sulphonylurea should be observed for adjustment of dose if required. Naproxen and other nonsteroidal anti-inflammatory drugs can reduce the antihypertensive effect of propranolol and other beta-blockers. Probenecid given concurrently increases naproxen anion plasma levels and extends its plasma half-life significantly. Due to the gastric pH elevating effects of H2-blockers, sucralfate and intensive antacid therapy, concomitant administration of EC-NAPROSYN is not recommended. Drug/Laboratory Test Interaction Naproxen may decrease platelet aggregation and prolong bleeding time. This effect should be kept in mind when bleeding times are determined. The administration of naproxen may result in increased urinary values for 17-ketogenic steroids because of an interaction between the drug and/or its metabolites with m-di-nitrobenzene used in this assay. Although 17-hydroxy-corticosteroid measurements (Porter-Silber test) do not appear to be artifactually altered, it is suggested that therapy with naproxen be temporarily discontinued 72 hours before adrenal function tests are performed if the Porter-Silber test is to be used. This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda NDA 17-581/S-106, 18-164/S-056, 18-965/S-014, 20-067/S-011 Page 16 Naproxen may interfere with some urinary assays of 5-hydroxy indoleacetic acid (5HIAA). Carcinogenesis A 2-year study was performed in rats to evaluate the carcinogenic potential of naproxen at rat doses of 8, 16, and 24 mg/kg/day (50, 100, and 150 mg/m2). The maximum dose used was 0.28 times the systemic exposure to humans at the recommended dose. No evidence of tumorigenicity was found. Pregnancy Teratogenic Effects Pregnancy Category C Reproduction studies have been performed in rats at 20 mg/kg/day (125 mg/m2/day, 0.23 times the human systemic exposure), rabbits at 20 mg/kg/day (220 mg/m2/day, 0.27 times the human systemic exposure), and mice at 170 mg/kg/day (510 mg/m2/day, 0.28 times the human systemic exposure) with no evidence of impaired fertility or harm to the fetus due to the drug. However, animal reproduction studies are not always predictive of human response. There are no adequate and well-controlled studies in pregnant women. NAPROSYN, EC-NAPROSYN, ANAPROX, ANAPROX DS and NAPROSYN Suspension should be used in pregnancy only if the potential benefit justifies the potential risk to the fetus. Nonteratogenic Effects There is some evidence to suggest that when inhibitors of prostaglandin synthesis are used to delay preterm labor there is an increased risk of neonatal complications such as necrotizing enterocolitis, patent ductus arteriosus and intracranial hemorrhage. Naproxen treatment given in late pregnancy to delay parturition has been associated with persistent pulmonary hypertension, renal dysfunction and abnormal prostaglandin E levels in preterm infants. Because of the known effects of nonsteroidal anti- inflammatory drugs on the fetal cardiovascular system (closure of ductus arteriosus), use during pregnancy (particularly late pregnancy) should be avoided. Labor and Delivery In rat studies with NSAIDs, as with other drugs known to inhibit prostaglandin synthesis, an increased incidence of dystocia, delayed parturition, and decreased pup survival occurred. Naproxen-containing products are not recommended in labor and delivery because, through its prostaglandin synthesis inhibitory effect, naproxen may adversely affect fetal circulation and inhibit uterine contractions, thus increasing the risk of uterine hemorrhage. The effects of NAPROSYN, EC-NAPROSYN, ANAPROX, ANAPROX DS and NAPROSYN Suspension on labor and delivery in pregnant women are unknown. Nursing Mothers The naproxen anion has been found in the milk of lactating women at a concentration equivalent to approximately 1% of maximum naproxen concentration in plasma. Because of the possible adverse effects of prostaglandin-inhibiting drugs on neonates, use in nursing mothers should be avoided. This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda NDA 17-581/S-106, 18-164/S-056, 18-965/S-014, 20-067/S-011 Page 17 Pediatric Use Safety and effectiveness in pediatric patients below the age of 2 years have not been established. Pediatric dosing recommendations for juvenile arthritis are based on well-controlled studies (see DOSAGE AND ADMINISTRATION). There are no adequate effectiveness or dose-response data for other pediatric conditions, but the experience in juvenile arthritis and other use experience have established that single doses of 2.5 to 5 mg/kg (as naproxen suspension, see DOSAGE AND ADMINISTRATION), with total daily dose not exceeding 15 mg/kg/day, are well tolerated in pediatric patients over 2 years of age. Geriatric Use Studies indicate that although total plasma concentration of naproxen is unchanged, the unbound plasma fraction of naproxen is increased in the elderly. Caution is advised when high doses are required and some adjustment of dosage may be required in elderly patients. As with other drugs used in the elderly, it is prudent to use the lowest effective dose. Experience indicates that geriatric patients may be particularly sensitive to certain adverse effects of nonsteroidal anti-inflammatory drugs. While age does not appear to be an independent risk factor for the development of peptic ulceration and bleeding with naproxen administration, eElderly or debilitated patients seem to tolerate peptic ulceration or bleeding less well when these events do occur. Most spontaneous reports of fatal GI events are in the geriatric population (see WARNINGS). Naproxen is known to be substantially excreted by the kidney, and the risk of toxic reactions to this drug may be greater in patients with impaired renal function. Because elderly patients are more likely to have decreased renal function, care should be taken in dose selection, and it may be useful to monitor renal function. Geriatric patients may be at a greater risk for the development of a form of renal toxicity precipitated by reduced prostaglandin formation during administration of nonsteroidal anti-inflammatory drugs (see WARNINGS, Renal Effects). ADVERSE REACTIONS Adverse reactions reported in controlled clinical trials in 960 patients treated for rheumatoid arthritis or osteoarthritis are listed below. In general, reactions in patients treated chronically were reported 2 to 10 times more frequently than they were in short-term studies in the 962 patients treated for mild to moderate pain or for dysmenorrhea. The most frequent complaints reported related to the gastrointestinal tract. A clinical study found gastrointestinal reactions to be more frequent and more severe in rheumatoid arthritis patients taking daily doses of 1500 mg naproxen compared to those taking 750 mg naproxen (see CLINICAL PHARMACOLOGY). In controlled clinical trials with about 80 pediatric patients and in well-monitored, open-label studies with about 400 pediatric patients with juvenile arthritis treated with naproxen, the incidence of rash and prolonged bleeding times were increased, the incidence of gastrointestinal and central nervous system reactions were about the same, and the incidence of other reactions were lower in pediatric patients than in adults. In patients taking naproxen in clinical trials, the most frequently reported adverse experiences in approximately 1% to 10% of patients are: Gastrointestinal (GI) Experiences, including: heartburn*, abdominal pain*, nausea*, constipation*, diarrhea, dyspepsia, stomatitis This label may not be the latest approved by FDA.

Those reactions occurring in less than 3% of the patients are unmarked. In patients taking NSAIDs, the following adverse experiences have also been reported in approximately 1% to 10% of patients. Gastrointestinal (GI) Experiences, including: flatulence, gross bleeding/perforation, GI ulcers (gastric/duodenal), vomiting General: abnormal renal function, anemia, elevated liver enzymes, increased bleeding time, rashes The following are additional adverse experiences reported in <1% of patients taking naproxen during clinical trials and through postmarketing reports. Those adverse reactions observed through postmarketing reports are italicized. Body as a Whole: anaphylactoid reactions, angioneurotic edema, menstrual disorders, pyrexia (chills and fever) Cardiovascular: congestive heart failure, vasculitis Gastrointestinal: gastrointestinal bleeding and/or perforation, hematemesis, jaundice, pancreatitis, vomiting, colitis, abnormal liver function tests, nonpeptic gastrointestinal ulceration, ulcerative stomatitis Hemic and Lymphatic: eosinophilia, leucopenia, melena, thrombocytopenia, agranulocytosis, granulocytopenia, hemolytic anemia, aplastic anemia Metabolic and Nutritional: hyperglycemia, hypoglycemia Nervous System: inability to concentrate, depression, dream abnormalities, insomnia, malaise, myalgia, muscle weakness, aseptic meningitis, cognitive dysfunction Respiratory: eosinophilic pneumonitis Dermatologic: alopecia, urticaria, skin rashes, toxic epidermal necrolysis, erythema multiforme, Stevens-Johnson syndrome, photosensitive dermatitis, photosensitivity reactions, including rare cases resembling porphyria cutanea tarda (pseudoporphyria) or epidermolysis bullosa. If skin fragility, blistering or other symptoms suggestive of pseudoporphyria occur, treatment should be discontinued and the patient monitored. Special Senses: hearing impairment Urogenital: glomerular nephritis, hematuria, hyperkalemia, interstitial nephritis, nephrotic syndrome, renal disease, renal failure, renal papillary necrosis This label may not be the latest approved by FDA.

Body as a Whole: fever, infection, sepsis, anaphylactic reactions, appetite changes, death Cardiovascular: hypertension, tachycardia, syncope, arrhythmia, hypotension, myocardial infarction Gastrointestinal: dry mouth, esophagitis, gastric/peptic ulcers, gastritis, glossitis, hepatitis, eructation, liver failure Hemic and Lymphatic: rectal bleeding, lymphadenopathy, pancytopenia Metabolic and Nutritional: weight changes Nervous System: anxiety, asthenia, confusion, nervousness, paresthesia, somnolence, tremors, convulsions, coma, hallucinations Respiratory: asthma, respiratory depression, pneumonia Dermatologic: exfoliative dermatitis Special Senses: blurred vision, conjunctivitis Urogenital: cystitis, dysuria, oliguria/polyuria, proteinuria OVERDOSAGE Significant naproxen overdosage may be characterized by lethargy, dizziness, drowsiness, epigastric pain, abdominal discomfort, heartburn, indigestion, nausea, transient alterations in liver function, hypoprothrombinemia, renal dysfunction, metabolic acidosis, apnea, disorientation or vomiting. Gastrointestinal bleeding can occur. Hypertension, acute renal failure, respiratory depression, and coma may occur, but are rare. Anaphylactoid reactions have been reported with therapeutic ingestion of NSAIDs, and may occur following an overdose. Because naproxen sodium may be rapidly absorbed, high and early blood levels should be anticipated. A few patients have experienced convulsions, but it is not clear whether or not these were drug-related. It is not known what dose of the drug would be life threatening. The oral LD50 of the drug is 543 mg/kg in rats, 1234 mg/kg in mice, 4110 mg/kg in hamsters, and greater than 1000 mg/kg in dogs. Patients should be managed by symptomatic and supportive care following a NSAID overdose. There are no specific antidotes. Hemodialysis does not decrease the plasma concentration of naproxen because of the high degree of its protein binding. Emesis and/or activated charcoal (60 to 100 g in adults, 1 to 2 g/kg in children) and/or osmotic cathartic may be indicated in patients seen within 4 hours of ingestion with symptoms or following a large overdose. Forced diuresis, alkalinization of urine or hemoperfusion may not be useful due to high protein binding. DOSAGE AND ADMINISTRATION Carefully consider the potential benefits and risks of NAPROSYN, EC-NAPROSYN, ANAPROX, ANAPROX DS and NAPROSYN Suspension and other treatment options before deciding to use NAPROSYN, EC-NAPROSYN, ANAPROX, ANAPROX DS and NAPROSYN Suspension. Use the lowest effective dose for the shortest duration consistent with individual patient treatment goals (see WARNINGS). This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda NDA 17-581/S-106, 18-164/S-056, 18-965/S-014, 20-067/S-011 Page 20 After observing the response to initial therapy with NAPROSYN, EC-NAPROSYN, ANAPROX, ANAPROX DS or NAPROSYN Suspension, the dose and frequency should be adjusted to suit an individual patient's needs. Different dose strengths and formulations (ie, tablets, suspension) of the drug are not necessarily bioequivalent. This difference should be taken into consideration when changing formulation. Although NAPROSYN, NAPROSYN Suspension, EC-NAPROSYN, ANAPROX and ANAPROX DS all circulate in the plasma as naproxen, they have pharmacokinetic differences that may affect onset of action. Onset of pain relief can begin within 30 minutes in patients taking naproxen sodium and within 1 hour in patients taking naproxen. Because EC-NAPROSYN dissolves in the small intestine rather than in the stomach, the absorption of the drug is delayed compared to the other naproxen formulations (see CLINICAL PHARMACOLOGY). The recommended strategy for initiating therapy is to choose a formulation and a starting dose likely to be effective for the patient and then adjust the dosage based on observation of benefit and/or adverse events. A lower dose should be considered in patients with renal or hepatic impairment or in elderly patients (see WARNINGS and PRECAUTIONS). Geriatric Patients Studies indicate that although total plasma concentration of naproxen is unchanged, the unbound plasma fraction of naproxen is increased in the elderly. Caution is advised when high doses are required and some adjustment of dosage may be required in elderly patients. As with other drugs used in the elderly, it is prudent to use the lowest effective dose. Patients With Moderate to Severe Renal Impairment Naproxen-containing products are not recommended for use in patients with moderate to severe and severe renal impairment (creatinine clearance <30 mL/min) (see WARNINGS: Renal Effects). Rheumatoid Arthritis, Osteoarthritis and Ankylosing Spondylitis NAPROSYN 250 mg or 375 mg or 500 mg twice daily twice daily twice daily ANAPROX 275 mg (naproxen 250 mg with 25 mg sodium) twice daily ANAPROX DS 550 mg (naproxen 500 mg with 50 mg sodium) twice daily NAPROSYN Suspension 250 mg (10 mL/2 tsp) or 375 mg (15 mL/3 tsp) or 500 mg (20 mL/4 tsp) twice daily twice daily twice daily EC-NAPROSYN 375 mg or 500 mg twice daily twice daily To maintain the integrity of the enteric coating, the EC-NAPROSYN tablet should not be broken, crushed or chewed during ingestion. During long-term administration, the dose of naproxen may be adjusted up or down depending on the clinical response of the patient. A lower daily dose may suffice for long-term administration. The This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda NDA 17-581/S-106, 18-164/S-056, 18-965/S-014, 20-067/S-011 Page 21 morning and evening doses do not have to be equal in size and the administration of the drug more frequently than twice daily is not necessary. In patients who tolerate lower doses well, the dose may be increased to naproxen 1500 mg/day for limited periods of up to 6 months when a higher level of anti-inflammatory/analgesic activity is required. When treating such patients with naproxen 1500 mg/day, the physician should observe sufficient increased clinical benefits to offset the potential increased risk. The morning and evening doses do not have to be equal in size and administration of the drug more frequently than twice daily does not generally make a difference in response (see CLINICAL PHARMACOLOGY). Juvenile Arthritis The use of NAPROSYN Suspension allows for more flexible dose titration. In pediatric patients, doses of 5 mg/kg/day produced plasma levels of naproxen similar to those seen in adults taking 500 mg of naproxen (see CLINICAL PHARMACOLOGY). The recommended total daily dose of naproxen is approximately 10 mg/kg given in 2 divided doses (ie, 5 mg/kg given twice a day). A measuring cup marked in 1/2 teaspoon and 2.5 milliliter increments is provided with the NAPROSYN Suspension. The following table may be used as a guide for dosing of NAPROSYN Suspension: Patient’s Weight Dose Administered as 13 kg (29 lb) 62.5 mg bid 2.5 mL (1/2 tsp) twice daily 25 kg (55 lb) 125 mg bid 5.0 mL (1 tsp) twice daily 38 kg (84 lb) 187.5 mg bid 7.5 mL (1 1/2 tsp) twice daily Management of Pain, Primary Dysmenorrhea, and Acute Tendonitis and Bursitis The recommended starting dose is 550 mg of naproxen sodium as ANAPROX/ANAPROX DS followed by 550 mg every 12 hours or 275 mg every 6 to 8 hours as required. The initial total daily dose should not exceed 1375 mg of naproxen sodium. Thereafter, the total daily dose should not exceed 1100 mg of naproxen sodium. Because the sodium salt of naproxen is more rapidly absorbed, ANAPROX/ANAPROX DS is recommended for the management of acute painful conditions when prompt onset of pain relief is desired. NAPROSYN may also be used but EC-NAPROSYN is not recommended for initial treatment of acute pain because absorption of naproxen is delayed compared to other naproxen-containing products (see CLINICAL PHARMACOLOGY, INDICATIONS AND USAGE). Acute Gout The recommended starting dose is 750 mg of NAPROSYN followed by 250 mg every 8 hours until the attack has subsided. ANAPROX may also be used at a starting dose of 825 mg followed by 275 mg every 8 hours. EC-NAPROSYN is not recommended because of the delay in absorption (see CLINICAL PHARMACOLOGY).

NSAID medicines may increase the chance of a heart attack or stroke that can lead to death. This chance increases: • with longer use of NSAID medicines • in people who have heart disease NSAID medicines should never be used right before or after a heart surgery called a “coronary artery bypass graft (CABG).” NSAID medicines can cause ulcers and bleeding in the stomach and intestines at any time during treatment. Ulcers and bleeding: • can happen without warning symptoms • may cause death The chance of a person getting an ulcer or bleeding increases with: • taking medicines called “corticosteroids” and “anticoagulants” • longer use • smoking • drinking alcohol • older age • having poor health NSAID medicines should only be used: • exactly as prescribed • at the lowest dose possible for your treatment • for the shortest time needed What are Non-Steroidal Anti-Inflammatory Drugs (NSAIDs)? NSAID medicines are used to treat pain and redness, swelling, and heat (inflammation) from medical conditions such as: • different types of arthritis • menstrual cramps and other types of short-term pain This label may not be the latest approved by FDA.

Do not take an NSAID medicine: • if you had an asthma attack, hives, or other allergic reaction with aspirin or any other NSAID medicine • for pain right before or after heart bypass surgery Tell your healthcare provider: • about all your medical conditions. • about all of the medicines you take. NSAIDs and some other medicines can interact with each other and cause serious side effects. Keep a list of your medicines to show to your healthcare provider and pharmacist. • if you are pregnant. NSAID medicines should not be used by pregnant women late in their pregnancy. • if you are breastfeeding. Talk to your doctor. What are the possible side effects of Non-Steroidal Anti-Inflammatory Drugs (NSAIDs)? Serious side effects include: • heart attack • stroke • high blood pressure • heart failure from body swelling (fluid retention) • kidney problems including kidney failure • bleeding and ulcers in the stomach and intestine • low red blood cells (anemia) • life-threatening skin reactions • life-threatening allergic reactions • liver problems including liver failure • asthma attacks in people who have asthma Other side effects include: • stomach pain • constipation • diarrhea • gas • heartburn • nausea • vomiting • dizziness Get emergency help right away if you have any of the following symptoms: • shortness of breath or trouble breathing • slurred speech • chest pain • swelling of the face or throat • weakness in one part or side of your body Stop your NSAID medicine and call your healthcare provider right away if you have any of the following symptoms: • nausea • more tired or weaker than usual • itching • your skin or eyes look yellow • stomach pain • flu-like symptoms • vomit blood • there is blood in your bowel movement or it is black and sticky like tar • unusual weight gain • skin rash or blisters with fever • swelling of the arms and legs, hands and feet These are not all the side effects with NSAID medicines.

This risk may increase with duration of use. Patients with cardiovascular disease or risk factors for cardiovascular disease may be at greater risk (see WARNINGS). • Naproxen as NAPROSYN, EC-NAPROSYN, ANAPROX, ANAPROX DS or NAPROSYN Suspension is contraindicated for the treatment of peri-operative pain in the setting of coronary artery bypass graft (CABG) surgery (see WARNINGS). Gastrointestinal Risk • NSAIDs cause an increased risk of serious gastrointestinal adverse events including bleeding, ulceration, and perforation of the stomach or intestines, which can be fatal. These events can occur at any time during use and without warning symptoms. Elderly patients are at greater risk for serious gastrointestinal events (see WARNINGS). DESCRIPTION 7 Naproxen is a proprionic acid derivative related to the arylacetic acid group of 8 nonsteroidal anti-inflammatory drugs. 9 The chemical names for naproxen and naproxen sodium are (S)-6-methoxy-α- 10 methyl-2-naphthaleneacetic acid and (S)-6-methoxy-α-methyl-2- 11 naphthaleneacetic acid, sodium salt, respectively. Naproxen and naproxen 12 sodium have the following structures, respectively: 13 14 Naproxen has a molecular weight of 230.26 and a molecular formula of 15 C14H14O3. Naproxen sodium has a molecular weight of 252.23 and a 16 molecular formula of C14H13NaO3. 17 Naproxen is an odorless, white to off-white crystalline substance. It is lipid- 18 soluble, practically insoluble in water at low pH and freely soluble in water at 19 high pH. The octanol/water partition coefficient of naproxen at pH 7.4 is 1.6 20 This label may not be the latest approved by FDA.

The 42 coating suspension for the ANAPROX DS 550 mg tablet may contain 43 hydroxypropyl methylcellulose 2910, Opaspray K-1-4227, polyethylene 44 glycol 8000 or Opadry YS-1-4216. 45 NAPROSYN (naproxen suspension) is available as a light orange-colored 46 opaque oral suspension containing 125 mg/5 mL of naproxen in a vehicle 47 containing sucrose, magnesium aluminum silicate, sorbitol solution and 48 sodium chloride (30 mg/5 mL, 1.5 mEq), methylparaben, fumaric acid, FD&C 49 Yellow No. 6, imitation pineapple flavor, imitation orange flavor and purified 50 water. The pH of the suspension ranges from 2.2 to 3.7. 51 CLINICAL PHARMACOLOGY 52 Pharmacodynamics 53 Naproxen is a nonsteroidal anti-inflammatory drug (NSAID) with analgesic 54 and antipyretic properties. The sodium salt of naproxen has been developed as 55 a more rapidly absorbed formulation of naproxen for use as an analgesic. The 56 mechanism of action of the naproxen anion, like that of other NSAIDs, is not 57 completely understood but may be related to prostaglandin synthetase 58 inhibition. 59 This label may not be the latest approved by FDA.

The different 62 dosage forms of NAPROSYN are bioequivalent in terms of extent of 63 absorption (AUC) and peak concentration (Cmax); however, the products do 64 differ in their pattern of absorption. These differences between naproxen 65 products are related to both the chemical form of naproxen used and its 66 formulation. Even with the observed differences in pattern of absorption, the 67 elimination half-life of naproxen is unchanged across products ranging from 68 12 to 17 hours. Steady-state levels of naproxen are reached in 4 to 5 days, and 69 the degree of naproxen accumulation is consistent with this half-life. This 70 suggests that the differences in pattern of release play only a negligible role in 71 the attainment of steady-state plasma levels. 72 Absorption 73 Immediate Release 74 After administration of NAPROSYN tablets, peak plasma levels are attained 75 in 2 to 4 hours. After oral administration of ANAPROX, peak plasma levels 76 are attained in 1 to 2 hours. The difference in rates between the two products 77 is due to the increased aqueous solubility of the sodium salt of naproxen used 78 in ANAPROX. Peak plasma levels of naproxen given as NAPROSYN 79 Suspension are attained in 1 to 4 hours. 80 Delayed Release 81 EC-NAPROSYN is designed with a pH-sensitive coating to provide a barrier 82 to disintegration in the acidic environment of the stomach and to lose integrity 83 in the more neutral environment of the small intestine. The enteric polymer 84 coating selected for EC-NAPROSYN dissolves above pH 6. When EC- 85 NAPROSYN was given to fasted subjects, peak plasma levels were attained 86 about 4 to 6 hours following the first dose (range: 2 to 12 hours). An in vivo 87 study in man using radiolabeled EC-NAPROSYN tablets demonstrated that 88 EC-NAPROSYN dissolves primarily in the small intestine rather than in the 89 stomach, so the absorption of the drug is delayed until the stomach is emptied. 90 When EC-NAPROSYN and NAPROSYN were given to fasted subjects 91 (n=24) in a crossover study following 1 week of dosing, differences in time to 92 peak plasma levels (Tmax) were observed, but there were no differences in total 93 absorption as measured by Cmax and AUC: 94 This label may not be the latest approved by FDA.

The presence of food prolonged the time the tablets remained in 105 the stomach, time to first detectable serum naproxen levels, and time to 106 maximal naproxen levels (Tmax), but did not affect peak naproxen levels 107 (Cmax). 108 Distribution 109 Naproxen has a volume of distribution of 0.16 L/kg. At therapeutic levels 110 naproxen is greater than 99% albumin-bound. At doses of naproxen greater 111 than 500 mg/day there is less than proportional increase in plasma levels due 112 to an increase in clearance caused by saturation of plasma protein binding at 113 higher doses (average trough Css 36.5, 49.2 and 56.4 mg/L with 500, 1000 and 114 1500 mg daily doses of naproxen, respectively). The naproxen anion has been 115 found in the milk of lactating women at a concentration equivalent to 116 approximately 1% of maximum naproxen concentration in plasma (see 117 PRECAUTIONS: Nursing Mothers). 118 Metabolism 119 Naproxen is extensively metabolized in the liver to 6-0-desmethyl naproxen, 120 and both parent and metabolites do not induce metabolizing enzymes. Both 121 naproxen and 6-0-desmethyl naproxen are further metabolized to their 122 respective acylglucuronide conjugated metabolites. 123 Excretion 124 The clearance of naproxen is 0.13 mL/min/kg. Approximately 95% of the 125 naproxen from any dose is excreted in the urine, primarily as naproxen (<1%), 126 6-0-desmethyl naproxen (<1%) or their conjugates (66% to 92%). The plasma 127 This label may not be the latest approved by FDA.

The 128 corresponding half-lives of both naproxen’s metabolites and conjugates are 129 shorter than 12 hours, and their rates of excretion have been found to coincide 130 closely with the rate of naproxen disappearance from the plasma. Small 131 amounts, 3% or less of the administered dose, are excreted in the feces. In 132 patients with renal failure metabolites may accumulate (see WARNINGS: 133 Renal Effects). 134 Special Populations 135 Pediatric Patients 136 In pediatric patients aged 5 to 16 years with arthritis, plasma naproxen levels 137 following a 5 mg/kg single dose of naproxen suspension (see DOSAGE AND 138 ADMINISTRATION) were found to be similar to those found in normal 139 adults following a 500 mg dose. The terminal half-life appears to be similar in 140 pediatric and adult patients. Pharmacokinetic studies of naproxen were not 141 performed in pediatric patients younger than 5 years of age. Pharmacokinetic 142 parameters appear to be similar following administration of naproxen 143 suspension or tablets in pediatric patients. EC-NAPROSYN has not been 144 studied in subjects under the age of 18. 145 Geriatric Patients 146 Studies indicate that although total plasma concentration of naproxen is 147 unchanged, the unbound plasma fraction of naproxen is increased in the 148 elderly, although the unbound fraction is < 1% of the total naproxen 149 concentration. Unbound trough naproxen concentrations in elderly subjects 150 have been reported to range from 0.12% to 0.19% of total naproxen 151 concentration, compared with 0.05% to 0.075% in younger subjects. The 152 clinical significance of this finding is unclear, although it is possible that the 153 increase in free naproxen concentration could be associated with an increase 154 in the rate of adverse events per a given dosage in some elderly patients. 155 Race 156 Pharmacokinetic differences due to race have not been studied. 157 Hepatic Insufficiency 158 Naproxen pharmacokinetics has not been determined in subjects with hepatic 159 insufficiency. 160 Renal Insufficiency 161 Naproxen pharmacokinetics has not been determined in subjects with renal 162 insufficiency. Given that naproxen, its metabolites and conjugates are 163 primarily excreted by the kidney, the potential exists for naproxen metabolites 164 This label may not be the latest approved by FDA.

Elimination of naproxen 165 is decreased in patients with severe renal impairment. Naproxen-containing 166 products are not recommended for use in patients with moderate to severe and 167 severe renal impairment (creatinine clearance <30 mL/min) (see 168 WARNINGS: Renal Effects). 169 CLINICAL STUDIES 170 General Information 171 Naproxen has been studied in patients with rheumatoid arthritis, osteoarthritis, 172 juvenile arthritis, ankylosing spondylitis, tendonitis and bursitis, and acute 173 gout. Improvement in patients treated for rheumatoid arthritis was 174 demonstrated by a reduction in joint swelling, a reduction in duration of 175 morning stiffness, a reduction in disease activity as assessed by both the 176 investigator and patient, and by increased mobility as demonstrated by a 177 reduction in walking time. Generally, response to naproxen has not been 178 found to be dependent on age, sex, severity or duration of rheumatoid arthritis. 179 In patients with osteoarthritis, the therapeutic action of naproxen has been 180 shown by a reduction in joint pain or tenderness, an increase in range of 181 motion in knee joints, increased mobility as demonstrated by a reduction in 182 walking time, and improvement in capacity to perform activities of daily 183 living impaired by the disease. 184 In a clinical trial comparing standard formulations of naproxen 375 mg bid 185 (750 mg a day) vs 750 mg bid (1500 mg/day), 9 patients in the 750 mg group 186 terminated prematurely because of adverse events. Nineteen patients in the 187 1500 mg group terminated prematurely because of adverse events. Most of 188 these adverse events were gastrointestinal events. 189 In clinical studies in patients with rheumatoid arthritis, osteoarthritis, and 190 juvenile arthritis, naproxen has been shown to be comparable to aspirin and 191 indomethacin in controlling the aforementioned measures of disease activity, 192 but the frequency and severity of the milder gastrointestinal adverse effects 193 (nausea, dyspepsia, heartburn) and nervous system adverse effects (tinnitus, 194 dizziness, lightheadedness) were less in naproxen-treated patients than in 195 those treated with aspirin or indomethacin. 196 In patients with ankylosing spondylitis, naproxen has been shown to decrease 197 night pain, morning stiffness and pain at rest. In double-blind studies the drug 198 was shown to be as effective as aspirin, but with fewer side effects. 199 In patients with acute gout, a favorable response to naproxen was shown by 200 significant clearing of inflammatory changes (eg, decrease in swelling, heat) 201 within 24 to 48 hours, as well as by relief of pain and tenderness. 202 This label may not be the latest approved by FDA.

Onset of pain relief can begin within 1 hour in 205 patients taking naproxen and within 30 minutes in patients taking naproxen 206 sodium. Analgesic effect was shown by such measures as reduction of pain 207 intensity scores, increase in pain relief scores, decrease in numbers of patients 208 requiring additional analgesic medication, and delay in time to remedication. 209 The analgesic effect has been found to last for up to 12 hours. 210 Naproxen may be used safely in combination with gold salts and/or 211 corticosteroids; however, in controlled clinical trials, when added to the 212 regimen of patients receiving corticosteroids, it did not appear to cause greater 213 improvement over that seen with corticosteroids alone. Whether naproxen has 214 a “steroid-sparing” effect has not been adequately studied. When added to the 215 regimen of patients receiving gold salts, naproxen did result in greater 216 improvement. Its use in combination with salicylates is not recommended 217 because there is evidence that aspirin increases the rate of excretion of 218 naproxen and data are inadequate to demonstrate that naproxen and aspirin 219 produce greater improvement over that achieved with aspirin alone. In 220 addition, as with other NSAIDs, the combination may result in higher 221 frequency of adverse events than demonstrated for either product alone. 222 In 51Cr blood loss and gastroscopy studies with normal volunteers, daily 223 administration of 1000 mg of naproxen as 1000 mg of NAPROSYN 224 (naproxen) or 1100 mg of ANAPROX (naproxen sodium) has been 225 demonstrated to cause statistically significantly less gastric bleeding and 226 erosion than 3250 mg of aspirin. 227 Three 6-week, double-blind, multicenter studies with EC-NAPROSYN 228 (naproxen) (375 or 500 mg bid, n=385) and NAPROSYN (375 or 500 mg bid, 229 n=279) were conducted comparing EC-NAPROSYN with NAPROSYN, 230 including 355 rheumatoid arthritis and osteoarthritis patients who had a recent 231 history of NSAID-related GI symptoms. These studies indicated that EC- 232 NAPROSYN and NAPROSYN showed no significant differences in efficacy 233 or safety and had similar prevalence of minor GI complaints. Individual 234 patients, however, may find one formulation preferable to the other. 235 Five hundred and fifty-three patients received EC-NAPROSYN during long- 236 term open-label trials (mean length of treatment was 159 days). The rates for 237 clinically-diagnosed peptic ulcers and GI bleeds were similar to what has been 238 historically reported for long-term NSAID use. 239 Geriatric Patients 240 The hepatic and renal tolerability of long-term naproxen administration was 241 studied in two double-blind clinical trials involving 586 patients.

Naproxen was administered at doses of 375 mg twice 244 daily or 750 mg twice daily for up to 6 months. Transient abnormalities of 245 laboratory tests assessing hepatic and renal function were noted in some 246 patients, although there were no differences noted in the occurrence of 247 abnormal values among different age groups. 248 INDICATIONS AND USAGE 249 Carefully consider the potential benefits and risks of NAPROSYN, EC- 250 NAPROSYN, ANAPROX, ANAPROX DS or NAPROSYN Suspension and 251 other treatment options before deciding to use NAPROSYN, EC- 252 NAPROSYN, ANAPROX, ANAPROX DS or NAPROSYN Suspension. Use 253 the lowest effective dose for the shortest duration consistent with individual 254 patient treatment goals (see WARNINGS). 255 Naproxen as NAPROSYN, EC-NAPROSYN, ANAPROX, ANAPROX DS or 256 NAPROSYN Suspension is indicated: 257 • For the relief of the signs and symptoms of rheumatoid arthritis 258 • For the relief of the signs and symptoms of osteoarthritis 259 • For the relief of the signs and symptoms of ankylosing spondylitis 260 • For the relief of the signs and symptoms of juvenile arthritis 261 Naproxen as NAPROSYN Suspension is recommended for juvenile 262 rheumatoid arthritis in order to obtain the maximum dosage flexibility based 263 on the patient’s weight. 264 Naproxen as NAPROSYN, ANAPROX, ANAPROX DS and NAPROSYN 265 Suspension is also indicated: 266 • For relief of the signs and symptoms of tendonitis 267 • For relief of the signs and symptoms of bursitis 268 • For relief of the signs and symptoms of acute gout 269 • For the management of pain 270 • For the management of primary dysmenorrhea 271 EC-NAPROSYN is not recommended for initial treatment of acute pain 272 because the absorption of naproxen is delayed compared to absorption from 273 other naproxen-containing products (see CLINICAL PHARMACOLOGY 274 and DOSAGE AND ADMINISTRATION). 275 This label may not be the latest approved by FDA.

Severe, rarely fatal, anaphylactic-like reactions to NSAIDs 283 have been reported in such patients (see WARNINGS: Anaphylactoid 284 Reactions and PRECAUTIONS: Preexisting Asthma). 285 NAPROSYN, EC-NAPROSYN, ANAPROX, ANAPROX DS and 286 NAPROSYN Suspension are contraindicated for the treatment of peri- 287 operative pain in the setting of coronary artery bypass graft (CABG) surgery 288 (see WARNINGS). 289 WARNINGS 290 CARDIOVASCULAR EFFECTS 291 Cardiovascular Thrombotic Events 292 Clinical trials of several COX-2 selective and nonselective NSAIDs of up to 293 three years duration have shown an increased risk of serious cardiovascular 294 (CV) thrombotic events, myocardial infarction, and stroke, which can be fatal. 295 All NSAIDS, both COX-2 selective and nonselective, may have a similar risk. 296 Patients with known CV disease or risk factors for CV disease may be at 297 greater risk. To minimize the potential risk for an adverse CV event in patients 298 treated with an NSAID, the lowest effective dose should be used for the 299 shortest duration possible. Physicians and patients should remain alert for the 300 development of such events, even in the absence of previous CV symptoms. 301 Patients should be informed about the signs and/or symptoms of serious CV 302 events and the steps to take if they occur. 303 There is no consistent evidence that concurrent use of aspirin mitigates the 304 increased risk of serious CV thrombotic events associated with NSAID use. 305 The concurrent use of aspirin and an NSAID does increase the risk of serious 306 GI events (see Gastrointestinal Effects – Risk of Ulceration, Bleeding, and 307 Perforation). 308 Two large, controlled, clinical trials of a COX-2 selective NSAID for the 309 treatment of pain in the first 10-14 days following CABG surgery found an 310 increased incidence of myocardial infarction and stroke (see 311 CONTRAINDICATIONS). 312 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda EC-NAPROSYN® (naproxen delayed-release tablets), NAPROSYN® (naproxen tablets), ANAPROX®/ANAPROX® DS (naproxen sodium tablets), NAPROSYN® (naproxen suspension) 10 Hypertension 313 NSAIDs, including NAPROSYN, EC-NAPROSYN, ANAPROX, 314 ANAPROX DS and NAPROSYN Suspension, can lead to onset of new 315 hypertension or worsening of pre-existing hypertension, either of which may 316 contribute to the increased incidence of CV events. Patients taking thiazides or 317 loop diuretics may have impaired response to these therapies when taking 318 NSAIDs. NSAIDs, including NAPROSYN, EC-NAPROSYN, ANAPROX, 319 ANAPROX DS and NAPROSYN Suspension, should be used with caution in 320 patients with hypertension. Blood pressure (BP) should be monitored closely 321 during the initiation of NSAID treatment and throughout the course of 322 therapy. 323 Congestive Heart Failure and Edema 324 Fluid retention, edema, and peripheral edema have been observed in some 325 patients taking NSAIDs. NAPROSYN, EC-NAPROSYN, ANAPROX, 326 ANAPROX DS and NAPROSYN Suspension should be used with caution in 327 patients with fluid retention, hypertension, or heart failure. Since each 328 ANAPROX or ANAPROX DS tablet contains 25 mg or 50 mg of sodium 329 (about 1 mEq per each 250 mg of naproxen), and each teaspoonful of 330 NAPROSYN Suspension contains 39 mg (about 1.5 mEq per each 125 mg of 331 naproxen) of sodium, this should be considered in patients whose overall 332 intake of sodium must be severely restricted. 333 Gastrointestinal Effects – Risk of Ulceration, Bleeding, and 334 Perforation 335 NSAIDs, including NAPROSYN, EC-NAPROSYN, ANAPROX, 336 ANAPROX DS and NAPROSYN Suspension, can cause serious 337 gastrointestinal (GI) adverse events including inflammation, bleeding, 338 ulceration, and perforation of the stomach, small intestine, or large intestine, 339 which can be fatal. 340 These serious adverse events can occur at any time, with or without warning 341 symptoms, in patients treated with NSAIDs. Only one in five patients, who 342 develop a serious upper GI adverse event on NSAID therapy, is symptomatic. 343 Upper GI ulcers, gross bleeding, or perforation caused by NSAIDs occur in 344 approximately 1% of patients treated for 3-6 months, and in about 2-4% of 345 patients treated for one year. These trends continue with longer duration of 346 use, increasing the likelihood of developing a serious GI event at some time 347 during the course of therapy. However, even short-term therapy is not without 348 risk. The utility of periodic laboratory monitoring has not been demonstrated, 349 nor has it been adequately assessed. Only 1 in 5 patients who develop a 350 serious upper GI adverse event on NSAID therapy is symptomatic. 351 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda EC-NAPROSYN® (naproxen delayed-release tablets), NAPROSYN® (naproxen tablets), ANAPROX®/ANAPROX® DS (naproxen sodium tablets), NAPROSYN® (naproxen suspension) 11 NSAIDs should be prescribed with extreme caution in those with a prior 352 history of ulcer disease or gastrointestinal bleeding. Patients with a prior 353 history of peptic ulcer disease and/or gastrointestinal bleeding who use 354 NSAIDs have a greater than 10-fold increased risk for developing a GI bleed 355 compared to patients with neither of these risk factors. Other factors that 356 increase the risk for GI bleeding in patients treated with NSAIDs include 357 concomitant use of oral corticosteroids or anticoagulants, longer duration of 358 NSAID therapy, smoking, use of alcohol, older age, and poor general health 359 status. Most spontaneous reports of fatal GI events are in elderly or debilitated 360 patients and therefore, special care should be taken in treating this population. 361 To minimize the potential risk for an adverse GI event in patients treated with 362 an NSAID, the lowest effective dose should be used for the shortest possible 363 duration. Patients and physicians should remain alert for signs and symptoms 364 of GI ulceration and bleeding during NSAID therapy and promptly initiate 365 additional evaluation and treatment if a serious GI adverse event is suspected. 366 This should include discontinuation of the NSAID until a serious GI adverse 367 event is ruled out. For high risk patients, alternate therapies that do not 368 involve NSAIDs should be considered. 369 Renal Effects 370 Long-term administration of NSAIDs has resulted in renal papillary necrosis 371 and other renal injury. Renal toxicity has also been seen in patients in whom 372 renal prostaglandins have a compensatory role in the maintenance of renal 373 perfusion. In these patients, administration of a nonsteroidal 374 anti-inflammatory drug may cause a dose-dependent reduction in 375 prostaglandin formation and, secondarily, in renal blood flow, which may 376 precipitate overt renal decompensation. Patients at greatest risk of this 377 reaction are those with impaired renal function, hypovolemia, heart failure, 378 liver dysfunction, salt depletion, those taking diuretics and ACE inhibitors, 379 and the elderly. Discontinuation of nonsteroidal anti-inflammatory drug 380 therapy is usually followed by recovery to the pretreatment state (see 381 WARNINGS: Advanced Renal Disease). 382 Advanced Renal Disease 383 No information is available from controlled clinical studies regarding the use 384 of NAPROSYN, EC-NAPROSYN, ANAPROX, ANAPROX DS or 385 NAPROSYN Suspension in patients with advanced renal disease. Therefore, 386 treatment with NAPROSYN, EC-NAPROSYN, ANAPROX, ANAPROX DS 387 and NAPROSYN Suspension is not recommended in these patients with 388 advanced renal disease. If NAPROSYN, EC-NAPROSYN, ANAPROX, 389 ANAPROX DS or NAPROSYN Suspension therapy must be initiated, close 390 monitoring of the patient’s renal function is advisable. 391 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda EC-NAPROSYN® (naproxen delayed-release tablets), NAPROSYN® (naproxen tablets), ANAPROX®/ANAPROX® DS (naproxen sodium tablets), NAPROSYN® (naproxen suspension) 12 Anaphylactoid Reactions 392 As with other NSAIDs, anaphylactoid reactions may occur in patients without 393 known prior exposure to either NAPROSYN, EC-NAPROSYN, ANAPROX, 394 ANAPROX DS or NAPROSYN Suspension. NAPROSYN, EC- 395 NAPROSYN, ANAPROX, ANAPROX DS and NAPROSYN Suspension 396 should not be given to patients with the aspirin triad. This symptom complex 397 typically occurs in asthmatic patients who experience rhinitis with or without 398 nasal polyps, or who exhibit severe, potentially fatal bronchospasm after 399 taking aspirin or other NSAIDs (see CONTRAINDICATIONS and 400 PRECAUTIONS: Preexisting Asthma). Emergency help should be sought 401 in cases where an anaphylactoid reaction occurs. 402 Skin Reactions 403 NSAIDs, including NAPROSYN, EC-NAPROSYN, ANAPROX, 404 ANAPROX DS and NAPROSYN Suspension, can cause serious skin adverse 405 events such as exfoliative dermatitis, Stevens-Johnson Syndrome (SJS), and 406 toxic epidermal necrolysis (TEN), which can be fatal. These serious events 407 may occur without warning. Patients should be informed about the signs and 408 symptoms of serious skin manifestations and use of the drug should be 409 discontinued at the first appearance of skin rash or any other sign of 410 hypersensitivity. 411 Pregnancy 412 In late pregnancy, as with other NSAIDs, NAPROSYN, EC-NAPROSYN, 413 ANAPROX, ANAPROX DS and NAPROSYN Suspension should be avoided 414 because it may cause premature closure of the ductus arteriosus. 415 PRECAUTIONS 416 General 417 Naproxen-containing products such as NAPROSYN, EC-NAPROSYN, 418 ANAPROX, ANAPROX DS, NAPROSYN SUSPENSION, ALEVE®, and 419 other naproxen products should not be used concomitantly since they all 420 circulate in the plasma as the naproxen anion. 421 NAPROSYN, EC-NAPROSYN, ANAPROX, ANAPROX DS and 422 NAPROSYN Suspension cannot be expected to substitute for corticosteroids 423 or to treat corticosteroid insufficiency. Abrupt discontinuation of 424 corticosteroids may lead to disease exacerbation. Patients on prolonged 425 corticosteroid therapy should have their therapy tapered slowly if a decision is 426 made to discontinue corticosteroids and the patient should be observed closely 427 for any evidence of adverse effects, including adrenal insufficiency and 428 exacerbation of symptoms of arthritis. 429 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda EC-NAPROSYN® (naproxen delayed-release tablets), NAPROSYN® (naproxen tablets), ANAPROX®/ANAPROX® DS (naproxen sodium tablets), NAPROSYN® (naproxen suspension) 13 Patients with initial hemoglobin values of 10 g or less who are to receive long- 430 term therapy should have hemoglobin values determined periodically. 431 The pharmacological activity of NAPROSYN, EC-NAPROSYN, 432 ANAPROX, ANAPROX DS and NAPROSYN Suspension in reducing fever 433 and inflammation may diminish the utility of these diagnostic signs in 434 detecting complications of presumed noninfectious, noninflammatory painful 435 conditions. 436 Because of adverse eye findings in animal studies with drugs of this class, it is 437 recommended that ophthalmic studies be carried out if any change or 438 disturbance in vision occurs. 439 Hepatic Effects 440 Borderline elevations of one or more liver tests may occur in up to 15% of 441 patients taking NSAIDs including NAPROSYN, EC-NAPROSYN, 442 ANAPROX, ANAPROX DS and NAPROSYN Suspension. Hepatic 443 abnormalities may be the result of hypersensitivity rather than direct toxicity. 444 These laboratory abnormalities may progress, may remain essentially 445 unchanged, or may be transient with continued therapy. The SGPT (ALT) test 446 is probably the most sensitive indicator of liver dysfunction. Notable 447 elevations of ALT or AST (approximately three or more times the upper limit 448 of normal) have been reported in approximately 1% of patients in clinical 449 trials with NSAIDs. In addition, rare cases of severe hepatic reactions, 450 including jaundice and fatal fulminant hepatitis, liver necrosis and hepatic 451 failure, some of them with fatal outcomes have been reported. 452 A patient with symptoms and/or signs suggesting liver dysfunction, or in 453 whom an abnormal liver test has occurred, should be evaluated for evidence 454 of the development of more severe hepatic reaction while on therapy with 455 NAPROSYN, EC-NAPROSYN, ANAPROX, ANAPROX DS or 456 NAPROSYN Suspension. 457 If clinical signs and symptoms consistent with liver disease develop, or if 458 systemic manifestations occur (eg, eosinophilia, rash, etc.), NAPROSYN, EC- 459 NAPROSYN, ANAPROX, ANAPROX DS or NAPROSYN Suspension 460 should be discontinued. 461 Chronic alcoholic liver disease and probably other diseases with decreased or 462 abnormal plasma proteins (albumin) reduce the total plasma concentration of 463 naproxen, but the plasma concentration of unbound naproxen is increased. 464 Caution is advised when high doses are required and some adjustment of 465 dosage may be required in these patients. It is prudent to use the lowest 466 effective dose. 467 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda EC-NAPROSYN® (naproxen delayed-release tablets), NAPROSYN® (naproxen tablets), ANAPROX®/ANAPROX® DS (naproxen sodium tablets), NAPROSYN® (naproxen suspension) 14 Hematological Effects 468 Anemia is sometimes seen in patients receiving NSAIDs, including 469 NAPROSYN, EC-NAPROSYN, ANAPROX, ANAPROX DS and 470 NAPROSYN Suspension. This may be due to fluid retention, occult or gross 471 GI blood loss, or an incompletely described effect upon erythropoiesis. 472 Patients on long-term treatment with NSAIDs, including NAPROSYN, EC- 473 NAPROSYN, ANAPROX, ANAPROX DS and NAPROSYN Suspension, 474 should have their hemoglobin or hematocrit checked if they exhibit any signs 475 or symptoms of anemia. 476 NSAIDs inhibit platelet aggregation and have been shown to prolong bleeding 477 time in some patients. Unlike aspirin, their effect on platelet function is 478 quantitatively less, of shorter duration, and reversible. Patients receiving either 479 NAPROSYN, EC-NAPROSYN, ANAPROX, ANAPROX DS or 480 NAPROSYN Suspension who may be adversely affected by alterations in 481 platelet function, such as those with coagulation disorders or patients 482 receiving anticoagulants, should be carefully monitored. 483 Preexisting Asthma 484 Patients with asthma may have aspirin-sensitive asthma. The use of aspirin in 485 patients with aspirin-sensitive asthma has been associated with severe 486 bronchospasm, which can be fatal. Since cross reactivity, including 487 bronchospasm, between aspirin and other nonsteroidal anti-inflammatory 488 drugs has been reported in such aspirin-sensitive patients, NAPROSYN, EC- 489 NAPROSYN, ANAPROX, ANAPROX DS and NAPROSYN Suspension 490 should not be administered to patients with this form of aspirin sensitivity and 491 should be used with caution in patients with preexisting asthma. 492 Information for Patients 493 Patients should be informed of the following information before initiating 494 therapy with an NSAID and periodically during the course of ongoing 495 therapy. Patients should also be encouraged to read the NSAID 496 Medication Guide that accompanies each prescription dispensed. 497 1. NAPROSYN, EC-NAPROSYN, ANAPROX, ANAPROX DS and 498 NAPROSYN Suspension, like other NSAIDs, may cause serious CV side 499 effects, such as MI or stroke, which may result in hospitalization and even 500 death. Although serious CV events can occur without warning symptoms, 501 patients should be alert for the signs and symptoms of chest pain, 502 shortness of breath, weakness, slurring of speech, and should ask for 503 medical advice when observing any indicative sign or symptoms. Patients 504 should be apprised of the importance of this follow-up (see WARNINGS: 505 Cardiovascular Effects). 506 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda EC-NAPROSYN® (naproxen delayed-release tablets), NAPROSYN® (naproxen tablets), ANAPROX®/ANAPROX® DS (naproxen sodium tablets), NAPROSYN® (naproxen suspension) 15 2. NAPROSYN, EC-NAPROSYN, ANAPROX, ANAPROX DS and 507 NAPROSYN Suspension, like other NSAIDs, can cause GI discomfort 508 and, rarely, serious GI side effects, such as ulcers and bleeding, which 509 may result in hospitalization and even death. Although serious GI tract 510 ulcerations and bleeding can occur without warning symptoms, patients 511 should be alert for the signs and symptoms of ulcerations and bleeding, 512 and should ask for medical advice when observing any indicative sign or 513 symptoms including epigastric pain, dyspepsia, melena, and hematemesis. 514 Patients should be apprised of the importance of this follow-up (see 515 WARNINGS: Gastrointestinal Effects: Risk of Ulceration, Bleeding, 516 and Perforation). 517 3. NAPROSYN, EC-NAPROSYN, ANAPROX, ANAPROX DS and 518 NAPROSYN Suspension, like other NSAIDs, can cause serious skin side 519 effects such as exfoliative dermatitis, SJS, and TEN, which may result in 520 hospitalizations and even death. Although serious skin reactions may 521 occur without warning, patients should be alert for the signs and 522 symptoms of skin rash and blisters, fever, or other signs of 523 hypersensitivity such as itching, and should ask for medical advice when 524 observing any indicative signs or symptoms. Patients should be advised to 525 stop the drug immediately if they develop any type of rash and contact 526 their physicians as soon as possible. 527 4. Patients should promptly report signs or symptoms of unexplained weight 528 gain or edema to their physicians. 529 5. Patients should be informed of the warning signs and symptoms of 530 hepatotoxicity (eg, nausea, fatigue, lethargy, pruritus, jaundice, right upper 531 quadrant tenderness, and “flu-like” symptoms). If these occur, patients 532 should be instructed to stop therapy and seek immediate medical therapy. 533 6. Patients should be informed of the signs of an anaphylactoid reaction (eg, 534 difficulty breathing, swelling of the face or throat). If these occur, patients 535 should be instructed to seek immediate emergency help (see 536 WARNINGS). 537 7. In late pregnancy, as with other NSAIDs, NAPROSYN, EC-NAPROSYN, 538 ANAPROX, ANAPROX DS and NAPROSYN Suspension should be 539 avoided because it may cause premature closure of the ductus arteriosus. 540 8. Caution should be exercised by patients whose activities require alertness 541 if they experience drowsiness, dizziness, vertigo or depression during 542 therapy with naproxen. 543 Laboratory Tests 544 Because serious GI tract ulcerations and bleeding can occur without warning 545 symptoms, physicians should monitor for signs or symptoms of GI bleeding. 546 Patients on long-term treatment with NSAIDs should have their CBC and a 547 chemistry profile checked periodically. If clinical signs and symptoms 548 consistent with liver or renal disease develop, systemic manifestations occur 549 (eg, eosinophilia, rash, etc.) or if abnormal liver tests persist or worsen, 550 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda EC-NAPROSYN® (naproxen delayed-release tablets), NAPROSYN® (naproxen tablets), ANAPROX®/ANAPROX® DS (naproxen sodium tablets), NAPROSYN® (naproxen suspension) 16 NAPROSYN, EC-NAPROSYN, ANAPROX, ANAPROX DS and 551 NAPROSYN Suspension should be discontinued. 552 Drug Interactions 553 ACE-inhibitors 554 Reports suggest that NSAIDs may diminish the antihypertensive effect of 555 ACE-inhibitors. This interaction should be given consideration in patients 556 taking NSAIDs concomitantly with ACE-inhibitors. 557 Antacids and Sucralfate 558 Concomitant administration of some antacids (magnesium oxide or aluminum 559 hydroxide) and sucralfate can delay the absorption of naproxen. 560 Aspirin 561 When naproxen as NAPROSYN, EC-NAPROSYN, ANAPROX, ANAPROX 562 DS or NAPROSYN Suspension is administered with aspirin, its protein 563 binding is reduced, although the clearance of free NAPROSYN, EC- 564 NAPROSYN, ANAPROX, ANAPROX DS or NAPROSYN Suspension is 565 not altered. The clinical significance of this interaction is not known; 566 however, as with other NSAIDs, concomitant administration of naproxen and 567 naproxen sodium and aspirin is not generally recommended because of the 568 potential of increased adverse effects. 569 Cholestyramine 570 As with other NSAIDs, Cconcomitant administration of cholestyramine can 571 delay the absorption of naproxen. 572 Diuretics 573 Clinical studies, as well as postmarketing observations, have shown that 574 NAPROSYN, EC-NAPROSYN, ANAPROX, ANAPROX DS and 575 NAPROSYN Suspension can reduce the natriuretic effect of furosemide and 576 thiazides in some patients. This response has been attributed to inhibition of 577 renal prostaglandin synthesis. During concomitant therapy with NSAIDs, the 578 patient should be observed closely for signs of renal failure (see 579 WARNINGS: Renal Effects), as well as to assure diuretic efficacy. 580 Lithium 581 NSAIDs have produced an elevation of plasma lithium levels and a reduction 582 in renal lithium clearance. The mean minimum lithium concentration 583 increased 15% and the renal clearance was decreased by approximately 20%. 584 These effects have been attributed to inhibition of renal prostaglandin 585 synthesis by the NSAID. Thus, when NSAIDs and lithium are administered 586 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda EC-NAPROSYN® (naproxen delayed-release tablets), NAPROSYN® (naproxen tablets), ANAPROX®/ANAPROX® DS (naproxen sodium tablets), NAPROSYN® (naproxen suspension) 17 concurrently, subjects should be observed carefully for signs of lithium 587 toxicity. 588 Methotrexate 589 NSAIDs have been reported to competitively inhibit methotrexate 590 accumulation in rabbit kidney slices. Naproxen, naproxen sodium and other 591 nonsteroidal anti-inflammatory drugs have been reported to reduce the tubular 592 secretion of methotrexate in an animal model. This may indicate that they 593 could enhance the toxicity of methotrexate. Caution should be used when 594 NSAIDs are administered concomitantly with methotrexate. 595 Warfarin 596 The effects of warfarin and NSAIDs on GI bleeding are synergistic, such that 597 users of both drugs together have a risk of serious GI bleeding higher than 598 users of either drug alone. No significant interactions have been observed in 599 clinical studies with naproxen and coumarin-type anticoagulants. However, 600 caution is advised since interactions have been seen with other nonsteroidal 601 agents of this class. The free fraction of warfarin may increase substantially in 602 some subjects and naproxen interferes with platelet function. 603 Other Information Concerning Drug Interactions 604 Naproxen is highly bound to plasma albumin; it thus has a theoretical 605 potential for interaction with other albumin-bound drugs such as coumarin- 606 type anticoagulants, sulphonylureas, hydantoins, other NSAIDs, and aspirin. 607 Patients simultaneously receiving naproxen and a hydantoin, sulphonamide or 608 sulphonylurea should be observed for adjustment of dose if required. 609 Naproxen and other nonsteroidal anti-inflammatory drugs can reduce the 610 antihypertensive effect of propranolol and other beta-blockers. 611 Probenecid given concurrently increases naproxen anion plasma levels and 612 extends its plasma half-life significantly. 613 Due to the gastric pH elevating effects of H2-blockers, sucralfate and intensive 614 antacid therapy, concomitant administration of EC-NAPROSYN is not 615 recommended. 616 Drug/Laboratory Test Interaction 617 Naproxen may decrease platelet aggregation and prolong bleeding time. This 618 effect should be kept in mind when bleeding times are determined. 619 The administration of naproxen may result in increased urinary values for 17- 620 ketogenic steroids because of an interaction between the drug and/or its 621 metabolites with m-di-nitrobenzene used in this assay. Although 17-hydroxy- 622 corticosteroid measurements (Porter-Silber test) do not appear to be 623 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda EC-NAPROSYN® (naproxen delayed-release tablets), NAPROSYN® (naproxen tablets), ANAPROX®/ANAPROX® DS (naproxen sodium tablets), NAPROSYN® (naproxen suspension) 18 artifactually altered, it is suggested that therapy with naproxen be temporarily 624 discontinued 72 hours before adrenal function tests are performed if the 625 Porter-Silber test is to be used. 626 Naproxen may interfere with some urinary assays of 5-hydroxy indoleacetic 627 acid (5HIAA). 628 Carcinogenesis 629 A 2-year study was performed in rats to evaluate the carcinogenic potential of 630 naproxen at rat doses of 8, 16, and 24 mg/kg/day (50, 100, and 150 mg/m2). 631 The maximum dose used was 0.28 times the systemic exposure to humans at 632 the recommended dose. No evidence of tumorigenicity was found. 633 Pregnancy 634 Teratogenic Effects 635 Pregnancy Category C 636 Reproduction studies have been performed in rats at 20 mg/kg/day 637 (125 mg/m2/day, 0.23 times the human systemic exposure), rabbits at 20 638 mg/kg/day (220 mg/m2/day, 0.27 times the human systemic exposure), and 639 mice at 170 mg/kg/day (510 mg/m2/day, 0.28 times the human systemic 640 exposure) with no evidence of impaired fertility or harm to the fetus due to the 641 drug. However, animal reproduction studies are not always predictive of 642 human response. There are no adequate and well-controlled studies in 643 pregnant women. NAPROSYN, EC-NAPROSYN, ANAPROX, ANAPROX 644 DS and NAPROSYN Suspension should be used in pregnancy only if the 645 potential benefit justifies the potential risk to the fetus. 646 Nonteratogenic Effects 647 There is some evidence to suggest that when inhibitors of prostaglandin 648 synthesis are used to delay preterm labor there is an increased risk of neonatal 649 complications such as necrotizing enterocolitis, patent ductus arteriosus and 650 intracranial hemorrhage. Naproxen treatment given in late pregnancy to delay 651 parturition has been associated with persistent pulmonary hypertension, renal 652 dysfunction and abnormal prostaglandin E levels in preterm infants. Because 653 of the known effects of nonsteroidal anti-inflammatory drugs on the fetal 654 cardiovascular system (closure of ductus arteriosus), use during pregnancy 655 (particularly late pregnancy) should be avoided. 656 Labor and Delivery 657 In rat studies with NSAIDs, as with other drugs known to inhibit 658 prostaglandin synthesis, an increased incidence of dystocia, delayed 659 parturition, and decreased pup survival occurred. Naproxen-containing 660 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda EC-NAPROSYN® (naproxen delayed-release tablets), NAPROSYN® (naproxen tablets), ANAPROX®/ANAPROX® DS (naproxen sodium tablets), NAPROSYN® (naproxen suspension) 19 products are not recommended in labor and delivery because, through its 661 prostaglandin synthesis inhibitory effect, naproxen may adversely affect fetal 662 circulation and inhibit uterine contractions, thus increasing the risk of uterine 663 hemorrhage. The effects of NAPROSYN, EC-NAPROSYN, ANAPROX, 664 ANAPROX DS and NAPROSYN Suspension on labor and delivery in 665 pregnant women are unknown. 666 Nursing Mothers 667 The naproxen anion has been found in the milk of lactating women at a 668 concentration equivalent to approximately 1% of maximum naproxen 669 concentration in plasma. Because of the possible adverse effects of 670 prostaglandin-inhibiting drugs on neonates, use in nursing mothers should be 671 avoided. 672 Pediatric Use 673 Safety and effectiveness in pediatric patients below the age of 2 years have 674 not been established. Pediatric dosing recommendations for juvenile arthritis 675 are based on well-controlled studies (see DOSAGE AND 676 ADMINISTRATION). There are no adequate effectiveness or dose-response 677 data for other pediatric conditions, but the experience in juvenile arthritis and 678 other use experience have established that single doses of 2.5 to 5 mg/kg (as 679 naproxen suspension, see DOSAGE AND ADMINISTRATION), with total 680 daily dose not exceeding 15 mg/kg/day, are well tolerated in pediatric patients 681 over 2 years of age. 682 Geriatric Use 683 Studies indicate that although total plasma concentration of naproxen is 684 unchanged, the unbound plasma fraction of naproxen is increased in the 685 elderly. Caution is advised when high doses are required and some adjustment 686 of dosage may be required in elderly patients. As with other drugs used in the 687 elderly, it is prudent to use the lowest effective dose. 688 Experience indicates that geriatric patients may be particularly sensitive to 689 certain adverse effects of nonsteroidal anti-inflammatory drugs. Elderly or 690 debilitated patients seem to tolerate peptic ulceration or bleeding less well 691 when these events do occur. Most spontaneous reports of fatal GI events are in 692 the geriatric population (see WARNINGS). 693 Naproxen is known to be substantially excreted by the kidney, and the risk of 694 toxic reactions to this drug may be greater in patients with impaired renal 695 function. Because elderly patients are more likely to have decreased renal 696 function, care should be taken in dose selection, and it may be useful to 697 monitor renal function. Geriatric patients may be at a greater risk for the 698 development of a form of renal toxicity precipitated by reduced prostaglandin 699 This label may not be the latest approved by FDA.

In general, reactions 704 in patients treated chronically were reported 2 to 10 times more frequently 705 than they were in short-term studies in the 962 patients treated for mild to 706 moderate pain or for dysmenorrhea. The most frequent complaints reported 707 related to the gastrointestinal tract. 708 A clinical study found gastrointestinal reactions to be more frequent and more 709 severe in rheumatoid arthritis patients taking daily doses of 1500 mg naproxen 710 compared to those taking 750 mg naproxen (see CLINICAL 711 PHARMACOLOGY). 712 In controlled clinical trials with about 80 pediatric patients and in well- 713 monitored, open-label studies with about 400 pediatric patients with juvenile 714 arthritis treated with naproxen, the incidence of rash and prolonged bleeding 715 times were increased, the incidence of gastrointestinal and central nervous 716 system reactions were about the same, and the incidence of other reactions 717 were lower in pediatric patients than in adults. 718 In patients taking naproxen in clinical trials, the most frequently reported 719 adverse experiences in approximately 1% to 10% of patients are: 720 Gastrointestinal (GI) Experiences, including: heartburn*, abdominal pain*, 721 nausea*, constipation*, diarrhea, dyspepsia, stomatitis 722 Central Nervous System: headache*, dizziness*, drowsiness*, 723 lightheadedness, vertigo 724 Dermatologic: pruritus (itching)*, skin eruptions*, ecchymoses*, sweating, 725 purpura 726 Special Senses: tinnitus*, visual disturbances, hearing disturbances 727 Cardiovascular: edema*, palpitations 728 General: dyspnea*, thirst 729 *Incidence of reported reaction between 3% and 9%. Those reactions 730 occurring in less than 3% of the patients are unmarked. 731 In patients taking NSAIDs, the following adverse experiences have also been 732 reported in approximately 1% to 10% of patients. 733 Gastrointestinal (GI) Experiences, including: flatulence, gross 734 bleeding/perforation, GI ulcers (gastric/duodenal), vomiting 735 This label may not be the latest approved by FDA.

Hypertension, acute renal failure, 794 respiratory depression, and coma may occur, but are rare. Anaphylactoid 795 reactions have been reported with therapeutic ingestion of NSAIDs, and may 796 occur following an overdose. Because naproxen sodium may be rapidly 797 absorbed, high and early blood levels should be anticipated. A few patients 798 have experienced convulsions, but it is not clear whether or not these were 799 drug-related. It is not known what dose of the drug would be life threatening. 800 The oral LD50 of the drug is 543 mg/kg in rats, 1234 mg/kg in mice, 4110 801 mg/kg in hamsters, and greater than 1000 mg/kg in dogs. 802 Patients should be managed by symptomatic and supportive care following a 803 NSAID overdose. There are no specific antidotes. Hemodialysis does not 804 decrease the plasma concentration of naproxen because of the high degree of 805 its protein binding. Emesis and/or activated charcoal (60 to 100 g in adults, 1 806 to 2 g/kg in children) and/or osmotic cathartic may be indicated in patients 807 This label may not be the latest approved by FDA.

This difference should be taken 822 into consideration when changing formulation. 823 Although NAPROSYN, NAPROSYN Suspension, EC-NAPROSYN, 824 ANAPROX and ANAPROX DS all circulate in the plasma as naproxen, they 825 have pharmacokinetic differences that may affect onset of action. Onset of 826 pain relief can begin within 30 minutes in patients taking naproxen sodium 827 and within 1 hour in patients taking naproxen. Because EC-NAPROSYN 828 dissolves in the small intestine rather than in the stomach, the absorption of 829 the drug is delayed compared to the other naproxen formulations (see 830 CLINICAL PHARMACOLOGY). 831 The recommended strategy for initiating therapy is to choose a formulation 832 and a starting dose likely to be effective for the patient and then adjust the 833 dosage based on observation of benefit and/or adverse events. A lower dose 834 should be considered in patients with renal or hepatic impairment or in elderly 835 patients (see WARNINGS and PRECAUTIONS). 836 Geriatric Patients 837 Studies indicate that although total plasma concentration of naproxen is 838 unchanged, the unbound plasma fraction of naproxen is increased in the 839 elderly. Caution is advised when high doses are required and some adjustment 840 of dosage may be required in elderly patients. As with other drugs used in the 841 elderly, it is prudent to use the lowest effective dose. 842 This label may not be the latest approved by FDA.

NAPROSYN 849 Suspension should be shaken gently before use. 850 During long-term administration, the dose of naproxen may be adjusted up or 851 down depending on the clinical response of the patient. A lower daily dose 852 may suffice for long-term administration. The morning and evening doses do 853 not have to be equal in size and the administration of the drug more frequently 854 than twice daily is not necessary. 855 In patients who tolerate lower doses well, the dose may be increased to 856 naproxen 1500 mg/day for limited periods of up to 6 months when a higher 857 level of anti-inflammatory/analgesic activity is required. When treating such 858 patients with naproxen 1500 mg/day, the physician should observe sufficient 859 increased clinical benefits to offset the potential increased risk. The morning 860 and evening doses do not have to be equal in size and administration of the 861 drug more frequently than twice daily does not generally make a difference in 862 response (see CLINICAL PHARMACOLOGY). 863 Juvenile Arthritis 864 The use of NAPROSYN Suspension is recommended for juvenile arthritis in 865 children 2 years or older because it allows for more flexible dose titration 866 based on the child’s weight. In pediatric patients, doses of 5 mg/kg/day 867 produced plasma levels of naproxen similar to those seen in adults taking 500 868 mg of naproxen (see CLINICAL PHARMACOLOGY). 869 The recommended total daily dose of naproxen is approximately 10 mg/kg 870 given in 2 divided doses (ie, 5 mg/kg given twice a day).

The following table may be used as a guide for 873 dosing of NAPROSYN Suspension: 874 Patient’s Weight Dose Administered as 875 13 kg (29 lb) 62.5 mg bid 2.5 mL (1/2 tsp) twice daily 876 25 kg (55 lb) 125 mg bid 5.0 mL (1 tsp) twice daily 877 38 kg (84 lb) 187.5 mg bid 7.5 mL (1 1/2 tsp) twice daily 878 Management of Pain, Primary Dysmenorrhea, and Acute 879 Tendonitis and Bursitis 880 The recommended starting dose is 550 mg of naproxen sodium as 881 ANAPROX/ANAPROX DS followed by 550 mg every 12 hours or 275 mg 882 every 6 to 8 hours as required. The initial total daily dose should not exceed 883 1375 mg of naproxen sodium. Thereafter, the total daily dose should not 884 exceed 1100 mg of naproxen sodium. Because the sodium salt of naproxen is 885 more rapidly absorbed, ANAPROX/ANAPROX DS is recommended for the 886 management of acute painful conditions when prompt onset of pain relief is 887 desired. NAPROSYN may also be used but EC-NAPROSYN is not 888 recommended for initial treatment of acute pain because absorption of 889 naproxen is delayed compared to other naproxen-containing products (see 890 CLINICAL PHARMACOLOGY, INDICATIONS AND USAGE). 891 Acute Gout 892 The recommended starting dose is 750 mg of NAPROSYN followed by 250 893 mg every 8 hours until the attack has subsided. ANAPROX may also be used 894 at a starting dose of 825 mg followed by 275 mg every 8 hours. EC- 895 NAPROSYN is not recommended because of the delay in absorption (see 896 CLINICAL PHARMACOLOGY). 897 HOW SUPPLIED 898 NAPROSYN Tablets: 250 mg: round, yellow, biconvex, engraved with NPR 899 LE 250 on one side and scored on the other.

NSAIDs may cause an increased risk of serious cardiovascular thrombotic events, myocardial infarction, and stroke, which can be fataL. This risk may increase with duration of use. Patients with cardiovascular disease or risk factors for cardiovascular disease may be at greater risk (see WARNINGS). . Naproxen as NAPROSYN, EC-NAPROSYN, ANAPROX, ANAPROX DS or NAPROSYN Suspension is contraindicated for the treatment of peri-operative pain in the setting of coronary artery bypass graft (CAB G) surgery (see WARNINGS). Gastrointestinal Risk . NSAIDs cause an increased risk of serious gastrointestinal adverse events including bleeding, ulceration, and perforation of the stomach or intestines, which can be fataL. These events can occur at any time during use and without warning symptoms. Elderly patients are at greater risk for serious gastrointestinal events (see WARNINGS). DESCRIPTION Naproxen is a proprionic acid derivative related to the arylacetic acid group of nonsteroidal anti-inflammatory drugs. The chemical names for naproxen and naproxen sodium are (S)-6-methoxy-a- methyl-2-naphthaleneacetic acid and (S)-6-methoxy-a-methyl-2- naphthaJeneacetic acid, sodium salt, respectively. Naproxen and naproxen sodium have the following stiyctures, respectively: ;Oo R..." napro'en (R..COOH) C14HI.o, mol wi 230.26 CH;¡ napro,.n ,odium (R.-COONa) C14H "NaO, mol wl 252.23 CH:iÜ Naproxen has a molecular weight of 230.26 and a molecular formula of C14H1403. Naproxen sodium has a molecular weight of 252.23 and a molecular formula of CI4H13Na03. Naproxen is an odorless, white to off-white crystallne substance. It is lipid- soluble, practically insoluble in water at low pH and freely soluble in water at high pH. The octanol/water partition coeffcient of naproxen at pH 7.4 is 1.6 1 This label may not be the latest approved by FDA.

The sodium salt of naproxen has been developed as a more rapidly absorbed formulation of naproxen for use as an analgesic. The mechanism of action of the naproxen anion, like that of other NSAIDs, is not completely understood but may be related to prostaglandin synthetase inhibition. 2 This label may not be the latest approved by FDA.

The different dosage forms of NAPROSYN are bioequivalent in terms of extent of absorption (AUC) and peak concentration (Cmax); however, the products do differ in their pattern of absorption. These differences between naproxen products are related to both the chemical form of naproxen used and its formulation. Even with the observed differences in pattern of absorption, the elimination half-life of naproxen is unchanged across products ranging from 12 to 17 hours. Steady-state levels ofnaproxen are reached in 4 to 5 days, and the degree of naproxen accumulation is consistent with this half-life. This suggests that the differences in pattern of release play only a negligible role in the attainment of steady-state plasma levels. Absorption Immediate Release After administration of NAPROSYN tablets, peak plasma levels are attained in 2 to 4 hours. After oral administration of ANAPROX, peak plasma levels are attained in 1 to 2 hours. The difference in rates between the two products is due to the increased aqueous solubility of the sodium salt of naproxen used in ANAPROX. Peak plasma levels of naproxen given as NAPROSYN Suspension arc attained in 1 to 4 hours. Delayed Release EC-NAPROSYN is designed with a pH-sensitive coating to provide a barrier to disintegration in the acidic environment of the stomach and to lose integrity in the more neutral environment of the small intestine. The enteric polymer coating selected for EC-NAPROSYN dissolves above pH 6. When EC- NAPROSYN was given to fasted subjects, peak plasma levels were attained about 4 to 6 hours following the first dose (range: 2 to 12 hours). An in vivo study in man using radio labeled EC-NAPROSYN tablets demonstrated that EC-NAPROSYN dissolves primarily in the small intestine rather than in the stomach, so the absorption of the drug is delayed until the stomach is emptied. When EC-NAPROSYN and NAPROSYN were given to fasted subjects (n=24) in a crossover study following 1 week of dosing, differences in time to peak plasma levels (T max) were observed, but there were no differences in total absorption as measured by Cmax and AUC: 3 This label may not be the latest approved by FDA.

Food Effects When EC-NAPROSYN was given as a single dose with food, peak plasma levels in most subjects were achieved in about 12 hours (range: 4 to 24 hours). Residence time in the small intestine until disintegration was independent of food intake. The presence of food prolonged the time the tablets remained in the stomach, time to first detectable serum naproxen levels, and time to maximal naproxen levels (T max), but did not affect peak naproxen levels (Cmax). Distribution Naproxen has a volume of distribution of 0.16 L/kg. At therapeutic levels naproxen is greater than 99% albumin-bound. At doses of naproxen greater than 500 mg/day there is less than proportional increase in plasma levels due to an increase in clearance caused by saturation of plasma protein binding at higher doses (average trough Css 36.5, 49.2 and 56.4 mg/L with 500, 1000 and 1500 mg daily doses of naproxen, respectively). The naproxen anion has been found in the milk of lactating women at a concentration equivalent to approximately 1% of maximum naproxen concentration in plasma (see PRECAUTIONS: Nursing Mothers). Metabolism Naproxen is extensively metabolized in the liver to 6-0-desmethyl naproxen, and both parent and metabolites do not induce metabolizing enzymes. Both naproxen and 6-0-desmethyl naproxen are further metabolized to their respective acyl glucuronide conjugated metabolites. Excretion The clearance of naproxen is 0.13 mL/min/kg. Approximately 95% of the naproxen from any dose is excreted in the urine, primarily as naproxen (":1 %), 6-0-desmethyl naproxen (":1 %) or their conjugates (66% to 92%). The plasma 4 This label may not be the latest approved by FDA.

The corresponding half-lives of both naproxen's metabolites and conjugates are shorter than 12 hours, and their rates of excretion have been found to coincide closely with the rate of naproxen disappearance from the plasma. Small amounts, 3% or less of the administered dose, are excreted in the feces. In patients with renal failure metabolites may accumulate (see WARNINGS: Renal Effects). Special Populations Pediatric Patients In pediatric patients aged 5 to 16 years with arthritis, plasma naproxen levels following a 5 mg/kg single dose ofnaproxen suspension (see DOSAGE AND ADMINISTRATION) were found to be similar to those found in normal adults following a 500 mg dose. The terminal half-life appears to be similar in pediatric and adult patients. Pharmacokinetic studies of naproxen were not pcrformed in pediatric patients younger than 5 years of age. Pharmacokinetic parameters appear to be similar following administration of naproxen suspension or tablets in pediatric patients. EC-NAPROSYN has not been studied in subjects under the age of 18. Geriatric Patients Studies indicate that although total plasma concentration of nàproxen is unchanged, the unbound plasma fraction of naproxen is increased in the elderly, although the unbound fraction is ..1% of the total naproxen concentration. Unbound trough naproxen concentrations in elderly subjects have been reported to range from 0.12% to 0.19% of total naproxen concentration, compared with 0.05% to 0.075% in younger subjects. The clinical significance of this finding is unclear, although it is possible that the increase in free naproxen concentration could be associated with an increase in the rate of adverse events per a given dosage in some elderly patients. Race Pharmacokinetic differences due to race have not been studied. Hepatic Insufficiency Naproxen pharmacokinetics has not been determined in subjects with hepatic insuffciency. Renal Insufficiency Naproxen pharmacokinetics has not been determined in subjects with renal insuffciency. Given that naproxen, its metabolites and conjugates are primarily excreted by the kidney, the potential exists for naproxen metabolites 5 This label may not be the latest approved by FDA.

Elimination of naproxen is decreased in patients with severe renal impairment. Naproxen-containing products are not recommended for use in patients with moderate to severe and severe renal impairment (creatinine clearance ..30 mL/min) (see WARNINGS: Renal Effects). CLINICAL STUDIES General Information Naproxen has been studied in patients with rheumatoid arthritis, osteoarthritis, juvenile arthritis, ankylosing spondylitis, tendonitis and bursitis, and acute gout. Improvement in patients treated for rheumatoid arthritis was demonstrated by a reduction in joint swellng, a reduction in duration of morning stiffness, a reduction in disease activity as assessed by both the investigator and patient, and by increased mobility as demonstrated by a reduction in walking time. Generally, response to naproxen has not been found to be dependent on age, sex, severity or duration of rheumatoid arthritis. In patients with osteoarthritis, the therapeutic action of naproxen has been shown by a reduction in joint pain or tenderness, an increase in range of motion in knee joints, increased mobility as demonstrated by a reduction in walking time, and improvement in capacity to perform activities of daily living impaired by the disease. In a clinical trial comparing standard formulations of naproxen 375 mg bid (750 mg a day) vs 750 mg bid (1500 mg/day), 9 patients in the 750 mg group terminated prematurely because of adverse events. Nineteen patients in the 1500 mg group terminated prematurely because of adverse events. Most of these adverse events were gastrointestinal events. In clinical studies in patients with rheumatoid arthritis, osteoarthritis, and juvenile arthritis, naproxen has been shown to be comparable to aspirin and indomethacin in controlling the aforementioned measures of disease activity, but the frequency and severity of the milder gastrointestinal adverse effects (nausea, dyspepsia, heartburn) and nervous system adverse effects (tinnitus, dizziness, lightheadcdness) were less in naproxen-treated patients than in those treated with aspirin or indomethacin. In patients with ankylosing spondylitis, naproxen has been shown to decrease night pain, morning stiffness and pain at rest. In double-blind studics the drug was shown to be as effective as aspirin, but with fewer side effects. In patients with acute gout, a favorable response to naproxen was shown by significant clearing of inflammatory changes (eg, decrease in swellng, heat) within 24 to 48 hours, as well as by relief of pain and tenderness. 6 This label may not be the latest approved by FDA.

Onset of pain relief can begin within 1 hour in patients taking naproxen and within 30 minutes in patients taking naproxen sodium. Analgesic effect was shown by such measures as reduction of pain intensity scores, increase in pain relief scores, decrease in numbers of patients requiring additional analgesic medication, and delay in time to remedication. The analgesic effect has been found to last for up to 12 hours. Naproxen may be used safely in combination with gold salts and/or corticosteroids; however, in controlled clinical trials, when added to the regimen of patients receiving corticosteroids, it did not appear to cause greater improvement over that seen with corticosteroids alone. Whether naproxcn has a "steroid-sparing" effect has not been adequately studied. When added to the regimen of patients receiving gold salts, naproxen did result in greater improvement. Its use in combination with salicylates is not recommended because there is evidence that aspirin increases the rate of excretion of naproxen and data are inadequate to demonstrate that naproxen and aspirin produce greater improvement over that achieved with aspirin alonc. In addition, as with other NSAIDs, the combination may result in higher frequency of adverse events than demonstrated for either product alone. In 51Cr blood loss and gastroscopy studies with normal volunteers, daily administration of 1000 mg of naproxen as 1000 mg of NAPROSYN (naproxen) or 1100 mg of ANAPROX (naproxen sodium) has been demonstrated to cause statistically significantly less gastric bleeding and erosion than 3250 mg of aspirin. Three 6-week, double-blind, multicenter studies with EC-NAPROSYN (naproxen) (375 or 500 mg bid, n=385) and NAPROSYN (375 or 500 mg bid, n=279) were conducted comparing EC-NAPROSYN with NAPROSYN, including 355 rheumatoid arthritis and osteoarthritis patients who had a recent history of NSAID-related GI symptoms. These studies indicated that EC- NAPROSYN and NAPROSYN showed no significant differences in effcacy or safety and had similar prevalence of minor GI complaints. Individual patients, however, may find one formulation preferable to the other. Five hundred and fifty-three patients received EC-NAPROSYN during long- term open-label trials (mean length of treatment was 159 days). The rates for clinically-diagnosed peptic ulcers and GI bleeds were similar to what has been historically reported for long-term NSAID use. Geriatric Patients The hepatic and renal tolerability of long-term naproxen administration was studied in two double-blind clinical trials involving 586 patients.

Naproxen was administered at doses of 375 mg twice daily or 750 mg twice daily for up to 6 months. Transient abnormalities of laboratory tests assessing hepatic and renal function were noted in some patients, although there were no differences noted in the occurrence of abnormal values among different age groups. INDICATIONS AND USAGE Carcfully consider the potential benefits and risks of NAPROSYN, EC- NAPROSYN, ANAPROX, ANAPROX DS or NAPROSYN Suspension and other treatment options before deciding to use NAPROSYN, EC- NAPROSYN, ANAPROX, ANAPROX DS or NAPROSYN Suspension. Use the lowest effective dose for the shortest duration consistent with individual patient treatment goals (see WARNINGS). Naproxen as NAPROSYN, EC-NAPROSYN, ANAPROX, ANAPROX DS or NAPROSYN Suspension is indicated: . For the relief of the signs and symptoms of rheumatoid arthritis . For the relief ofthe signs and symptoms of osteoarthritis . For the relief of the signs and symptoms of ankylosing spondylitis . For the relief of the signs and symptoms of juvenile arthritis Naproxen as NAPROSYN Suspension is recommended for juvenile rheumatoid arthritis in order to obtain the maximum dosage flexibility based on the patient's weight. Naproxen as NAPROSYN~ ANAPROX, ANAPROX DS and NAPROSYN Suspension is also indicated: . For relief of the signs and symptoms of tendonitis . For relief of the signs and symptoms of bursitis . For relief of the signs and symptoms of acute gout . For the management of pain . For the management of primary dysmenorrhea EC-NAPROSYN is not recommended for initial treatment of acute pain because the absorption of naproxen is delayed compared to absorption from other naproxen-containing products (see CLINICAL PHARMACOLOGY and DOSAGE AND ADMINISTRATION). 8 This label may not be the latest approved by FDA.

NAPROSYN, EC-NAPROSYN,' ANAPROX, ANAPROX DS and NAPROSYN Suspension should not be given to patients who have experienced asthma, urticaria, or allergic-type reactions after taking aspirin or other NSAIDs. Severe, rarely fatal, anaphylactic-like reactions to NSAIDs have been reported in such patients (see WARNINGS: Anaphylactoid Reactions and PRECAUTIONS: Preexisting Asthma). NAPROSYN, EC-NAPROSYN, ANAPROX, ANAPROX DS and NAPROSYN Suspension are contraindicated for the treatment of peri- operative pain in the setting of coronary artery bypass graft (CAB G) surgery (see WARNINGS). WARNINGS CARDIOVASCULAR EFFECTS Cardiovascular Thrombotic Events Clinical trials of several COX-2 selective and nonselective NSAIDs of up to three years duration have shown an increased risk of serious cardiovascular (CV) thrombotic events, myocardial infarction, and stroke, which can be fataL. All NSAIDs, both COX-2 selective and nonselective, may have a similar risk. Patients with known CV disease or risk factors for CV disease may be at greater risk. To minimize the potential risk for an adverse CV event in patients treated with an NSAID, the lowest effective dose should be used for the shortest duration possible. Physicians and patients should remain alert for the development of such events, even in the absence of previous CV symptoms. Patients should be informed about the signs and/or symptoms of serious CV events and the steps to take if they occur. There is no consistent evidence that concurrent use of aspirin mitigatcs the increased risk of serious CV thrombotic events associated with NSAID use. The concurrent use of aspirin and an NSAID does increase the risk of serious GI events (see Gastrointestinal Effects - Risk of Ulceration, Bleeding, and Perforation). Two large, controlled, clinical trials of a COX-2 selective NSAID for the treatment of pain in the first 10-14 days following CABG surgery found an increased incidence of myocardial infarction and stroke. (see CONTRAINDICA TIONS). 9 This label may not be the latest approved by FDA.

Patients taking thiazid~s or loop diuretics may have impaired response to these therapies when taking NSAIDs. NSAIDs, including NAPROSYN, EC-NAPROSYN, ANAPROX, ANAPROX DS and NAPROSYN Suspension, should be used with caution in patients with hypertension. Blood pressure (BP) should be monitored closely during the initiation of NSAID treatment and throughout the course of therapy. Congestive Heart Failure and Edema Fluid retention, edema, and peripheral edema have been observed in some patients taking NSAIDs. NAPROSYN, EC-NAPROSYN, ANAPROX, ANAPROX DS and NAPROSYN Suspension should be used with caution in patients with fluid retention, hypertension, or hear failure. Since each ANAPROX or ANAPROX DS tablet contains 25 mg or 50 mg of sodium (about 1 mEq per each 250 mg of naproxen), and each teaspoonful of NAPROSYN Suspension contains 39 mg (about 1.5 mEq per each 125 mg of naproxen) of sodium, this should be considered in patients whose overall intakc of sodium must be severely restricted. Gastrointestinal Effects - Risk of Ulceration, Bleeding, and Perforation NSAIDs, including NAPROSYN, EC-NAPROSYN, ANAPROX, ANAPROX DS and NAPROSYN Suspension, can cause seflOUS gastrointestinal (GI) adverse events including inflammation, bleeding, ulceration, and perforation of the stomach, small intestine, or large intestine, which can be fataL. These serious adverse events can occur at any time, with or without warning symptoms, in patients treated with NSAIDs. Only one in five patients, who develop a serious upper GI adverse event on NSAID therapy, is symptomatic. Upper GI ulcers, gross bleeding, or perforation caused by NSAIDs OCCU! in approximately 1 % of patients treated for 3-6 months, and in about 2-4% of patients treated for one year. These trends continue with longer duration of use, increasing the likelihood of developing a serious GI event at some time during the course of therapy. However, even short-term therapy is not without risk. The utility of periodic laboratory monitoring has not been demonstrated, nor has it been adequately assessed. Only 1 in 5 patients who develop a serious upper GI adverse event on NSAID therapy is symptomatic. 10 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda EC-NAPROSYNW (naproxen delayed-release tablets), NAPROSYNW (naproxen tablets), ANAPROX(j/ANAPROX(j DS (naproxen sodium tablets), NAPROSYNW (naproxen suspension) NSAIDs should be prescribed with extreme caution in those with a prior history of ulcer disease or gastrointestinal bleeding. Patients with a prior history of peptic ulcer disease and/or gastrointestinal bleeding who use NSAIDs have a greater than 10-fold increased risk for developing a GI bleed compared to patients with neither of these risk factors. Other factors that increase the risk for GI bleeding in patients treated with NSAIDs include concomitant use of oral corticosteroids or anticoagulants, longer duration of NSAID therapy, smoking, use of alcohol, older age, and poor general health status. Most spontaneous reports of fatal GI events are in elderly or debilitated patients and therefore, special care should be taken in treating this population. To minimize the potential risk for an adverse GI event in patients treated with an NSAID, the lowest effective dose should be used for the shortest possible duration. Patients and physicians should remain alert for signs and symptoms of GI ulceration and bleeding during NSAID therapy and promptly initiate additional evaluation and treatment if a serious GI adverse event is suspected. This should include discontinuation of the NSAID until a serious GI adverse event is ruled out. For high risk patients, alternate therapies that do not involve NSAIDs should be considered. Epidemiological studies, both of the case-control and cohort design, have demonstrated an association between use of psychotropic drugs that interfere with serotonin reuptake and the occurrence of upper gastrointestinal bleeding. In two studies, concurrent use of an NSAID or aspirin potcntiated the risk of bleeding (see PRECAUTIONS - Drug Interactions). Although these studies focused on upper gastrointestinal bleeding, there is reason to belicve that bleeding at other sites may be similarly potentiated. NSAIDs should be given with care to patients with a history of inflammatory bowel disease (ulcerative colitis, Crohn's disease) as their condition may be exacerbated. Renal Effects Long-term administration of NSAIDs has resulted in renal papilary necrosis and other renal injury. Renal toxicity has also been seen in patients in whom renal prostaglandins have a compensatory role in the maintenance of renal perfusion. In these patients, administration of a nonsteroidal anti-inflammatory drug may cause a dose-dependent reduction in prostaglandin formation and, secondarily, in renal blood flow, which may precipitate overt renal decompensation. Patients at greatest risk of this reaction are those with impaired renal function, hypovolemia, heart failure, liver dysfunction, salt depletion, those taking diuretics and ACE inhibitors, and the elderly. Discontinuation of nonsteroidal anti-inflammatory drug therapy is usually followcd by recovery to the pretreatment state (see WARNINGS: Advanced Renal Disease). 11 This label may not be the latest approved by FDA.

Therefore, treatment with NAPROSYN, EC-NAPROSYN, ANAPROX, ANAPROX DS and NAPROSYN Suspension is not recommended in these patients with advanced renal disease. If NAPROSYN, EC-NAPROSYN, ANAPROX, ANAPROX DS or NAPROSYN Suspension therapy must be initiated, close monitoring of the patient's renal function is advisable. Anaphylactoid Reactions As with other NSAIDs, anaphylactoid reactions may occur in patients without known prior exposure to NAPROSYN, EC-NAPROSYN, ANAPROX, ANAPROX DS or NAPROSYN Suspension. NAPROSYN, EC- NAPROSYN, ANAPROX, ANAPROX DS and NAPROSYN Suspension should not be given to patients with the aspirin triad. This symptom complex typically occurs in asthmatic patients who experience rhinitis with or without nasal polyps, or who exhibit severe, potentially fatal bronchospasm after taking aspirin or other NSAIDs (see CONTRAINDICATIONS and PRECAUTIONS: Preexisting Asthma). Emergency help should be sought in cases where an anaphylactoid reaction occurs. Anaphylactoid reactions, like anaphylaxis, may have a fatal outcome. Skin Reactions NSAIDs, including NAPROSYN, EC-NAPROSYN, ANAPROX, ANAPROX DS and NAPROSYN Suspension, can cause serious skin adverse events such as exfoliative dermatitis, Stevens-Johnson Syndrome (SJS), and toxic epidermal necrolysis (TEN), which can be fataL. These serious events may occur without warning. Patients should be inforied about the signs and symptoms of serious skin manifestations and use of the drug should be discontinued at the first appearance of skin rash or any other sign of hypersensitivity. Pregnancy In late pregnancy, as with other NSAIDs, NAPROSYN, EC-NAPROSYN, ANAPROX, ANAPROX DS and NAPROSYN Suspension should be avoided because it may cause premature closure of the ductus areriosus. PRECAUTIONS General Naproxen-containing products such as NAPROSYN, EC-NAPROSYN, ANAPROX, ANAPROX DS, NAPROSYN SUSPENSION, ALEVE~, and 12 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda EC-NAPROSYNW (naproxen delayed-release tablets), NAPROSYN (naproxen tablets), ANAPROX(j/ANAPROX(j DS (naproxen sodium tablets), NAPROSYN (naproxen suspension) other naproxen products should not be used concomitantly since they all circulate in the plasma as the naproxen anion. NAPROSYN, EC-NAPROSYN, ANAPROX, ANAPROX DS and NAPROSYN Suspcnsion cannot be expected to substitute for corticosteroids or to treat corticosteroid insufficiency. Abrupt discontinuation of corticosteroids may lead to disease exacerbation. Patients on prolonged corticosteroid therapy should have their therapy tapered slowly if a decision is made to discontinue corticosteroids and the patient should be observed closely for any evidence of adverse effects, including adrenal insufficiency and exacerbation of symptoms of arthritis. Patients with initial hemoglobin values of 109 or less who are to receive long- term therapy should have hemoglobin values determined periodically. The pharmacological activity of NAPROSYN, EC-NAPROSYN, ANAPROX, ANAPROX DS and NAPROSYN Suspension in reducing fever and inflammation may diminish the utility of these diagnostic signs in detecting complications of presumed noninfectious, noninflammatory painful conditions. Because of adverse eye findings in animal studies with drugs of this class, it is recommended that ophthalmic studies be carried out if any change or disturbance in vision occurs. Hepatic Effects Borderline elevations of one or more liver tests may occur in up to 15% of patients taking NSAIDs including NAPROSYN, EC-NAPROSYN, ANAPROX, ANAPROX DS and NAPROSYN Suspension. Hepatic abnormalities may be the result of hypersensitivity rather than direct toxicity. These laboratory abnormalities may progress, may remain essentially unchanged, or may be transient with continued therapy. The SGPT (AL T) test is probably the most sensitive indicator of liver dysfunction. Notable elevations of AL T or AST (approximately three or more times the upper limit of normal) have been reported in approximately 1 % of patients in clinical trials with NSAIDs. In addition, rare cases of severe hepatic reactions, including jaundice and fatal fulminant hepatitis, liver necrosis and hepatic failure, some of them with fatal outcomes have been reported. A patient with .symptoms and/or signs suggesting liver dysfunction, or in whom an abnormal liver test has occurred, should be evaluated for evidence of the development of more severe hepatic reaction while on therapy with NAPROSYN, EC-NAPROSYN, ANAPROX, ANAPROX DS or NAPROSYN Suspension. 13 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda EC-NAPROSYNW (naproxen delayed-release tablets), NAPROSY~ (naproxen tablets), ANAPROX(j/ANAPROX(j DS (naproxen sodium tablets), NAPROSYN(j (naproxen suspension) If clinical signs and symptoms consistent with liver disease develop, or if systemic manifestations occur (eg, eosinophilia, rash, etc.), NAPROSYN, EC- NAPROSYN, ANAPROX, ANAPROX DS or NAPROSYN Suspension should be discontinued. Chronic alcoholic liver disease and probably other diseases with decreased or abnormal plasma proteins (albumin) reduce the total plasma concentration of naproxen, but the plasma concentration of unbound naproxen is increased. Caution is advised when high doses are required and some adjustmcnt of dosage may be required in these patients. It is prudent to use the lowest effective dose. Hematological Effects Anemia is sometimes seen in patients receiving NSAIDs, including NAPROSYN, EC-NAPROSYN, ANAPROX, ANAPROX DS and NAPROSYN Suspension. This may be due to fluid retention, occult or gross GI blood loss, or an incompletely described effect upon erythropoiesis. Patients on long-term treatment with NSAIDs, including NAPROSYN, EC- NAPROSYN, ANAPROX, ANAPROX DS and NAPROSYN Suspension, should have their hemoglobin or hematocrit checked if they exhibit any signs or symptoms of anemia. NSAIDs inhibit platelet aggregation and have been shown to prolong bleeding time in some patients. Unlike aspirin, their effect on platelet fuction is quantitatively less, of shorter duration, and reversible. Patients receiving either NAPROSYN, EC-NAPROSYN, ANAPROX, ANAPROX DS or NAPROSYN Suspension who may be adversely affected by alterations in platelct function, such as those with coagulation disorders or patients receiving anticoagulants, should be carefully monitored. Preexisting Asthma Patients with asthma may have aspirin-sensitive asthma. The use of aspirin in patients with aspirin-sensitive asthma has been associated with severe bronchospasm, which can be fataL. Since cross reactivity, including bronchospasm, between aspirin and other nonsteroidal anti-inflammatory drugs has been reported in such aspirin-sensitive patients, NAPROSYN, EC- NAPROSYN, ANAPROX, ANAPROX DS and NAPROSYN Suspension should not be administered to patients with this form of aspirin sensitivity and should be used with caution in patients with preexisting asthma. Information for Patients Patients should be informed of the following information before initiating therapy with an NSAID and periodically during the course of ongoing 14 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda EC-NAPROSYNW (naproxen delayed-release tablets), NAPROSYNW (naproxen tablets), ANAPROX(j/ANAPROX(j DS (naproxen sodium tablets), N.APROSYN (naproxen suspension) therapy. Patients should also be encouraged to read the NSAID Medication Guide that accompanies each prescription dispensed. 1. NAPROSYN, EC-NAPROSYN, ANAPROX, ANAPROX DS and NAPROSYN Suspension, like other NSAIDs, may causc serious CV side effects, such as MI or stroke, which may result in hospitalization and even death. Although serious CV events can occur without warning symptoms, patients should be alert for the signs and symptoms of chest pain, shortness of breath, weakness, slurring of speech, and should ask for medical advice when obsei:ving any indicative sign or symptoms. Patients should be apprised ofthe importance of this follow-up (see WARNINGS: Cardiovascular Effects). 2. NAPROSYN, EC-NAPROSYN, ANAPROX, ANAPROX DS and NAPROSYN Suspension, like other ;N"SAIDs, can cause GI discomfort and, rarely, serious GI side cffccts, such as ulcers and bleeding, which may result in hospitalization and even death. Although serious GI tract ulcerations and bleeding can occur without warning symptoms, patients should be alert for the signs and symptoms of ulcerations and bleeding, and should ask for medical advice when observing any indicative sign or symptoms including epigastric pain, dyspepsia, melena, and hematemesis. Patients should be apprised ofthe importance of this follow-up (see WARNINGS: Gastrointestinal Effects: Risk of Ulceration, Bleeding, and Perforation). 3. NAPROSYN, EC-NAPROSYN, ANAPROX, ANAPROX DS and NAPROSYN Suspension, like other NSAIDs, can cause serious skin side effects such as exfoliative dermatitis, SJS, and TEN, which may result in hospitalizations and even death. Although serious skin reactions may occur without warning, patients should be alert for the signs and symptoms of skin rash and blisters, fever, or other signs of hypersensitivity such as itching, and should ask for medical advice when observing any indicative signs or symptoms. Patients should be advised to stop the drug immediately if they develop any type of rash and contact their physicians as soon as possible. 4. Patients should promptly report signs or symptoms of unexplained weight gain or edema to their physicians. 5. Patients should be informed of the warning signs and symptoms of hepatotoxicity (eg, nausea, fatigue, lethargy, pruritus, jaundice, right upper quadrant tenderness, and "flu-like" symptoms). If these occur, patients should be instructed to stop therapy and seek immediate medical therapy. 6. Patients should be informed of the signs of an anaphylactoid reaction (eg, diffculty breathing, swelling of the face or throat). If these occur, patients should be instructed to seek in'mediate emergency help (see WARNINGS). 15 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda EC-NAPROSYNW (naproxen delayed-release tablets), NAPROSYN(j (naproxen tablets), ANAPROX(j/ANAPROX(j DS (naproxen sodium tablets), NAPROSYNW (naproxen suspension) 7. In late pregnancy, as with other NSAIDs, NAPROSYN, EC-NAPROSYN, ANAPROX, ANAPROX DS and NAPROSYN Suspension should be avoided because it may cause premature closure of the ductus arteriosus. 8. Caution should be exercised by patients whose activities require alertness if they experience drowsiness, dizziness, vertigo or depression during therapy with naproxen. Laboratory Tests Because serious GI tract ulcerations and bleeding can occur without warning symptoms, physicians should monitor for signs or symptoms of GI bleeding. Patients on long-term treatment with NSAIDs should have their CBC and a chemistry profie checked periodically. If clinical signs and symptoms consistent with liver or renal disease develop, systemic manifestations occur (eg, eosinophilia, rash, etc.) or if abnormal liver tests persist or worsen, NAPROSYN, EC-NAPROSYN, ANAPROX, ANAPROX DS and NAPROSYN Suspcnsion should be discontinued. Drug Interactions ACE-inhibitors Reports suggest that NSAIDs may diminish the antihypertensive effect of ACE-inhibitors. This interaction should be given consideration in patients taking NSAIDs concomitantly with ACE-inhibitors. Antacids and Sucralfate Concomitant administration of some antacids (magnesium oxide or aluminum hydroxide) and sucralfate can delay the absorption of naproxen. Aspirin When naproxen as NAPROSYN, EC-NAPROSYN, ANAPROX, ANAPROX DS or NAPROSYN Suspension is administered with aspirin, its protein binding is reduced, although the clearance of free NAPROSYN, EC- NAPROSYN, ANAPROX, ANAPROX DS or NAPROSYN Suspension is not altered. The clinical significance of this interaction is not known; however, as with other NSAIDs, concomitant administration of naproxen and naproxen sodium and aspirin is not generally recommended because of the potential of increased adverse effects. Ch o/es tyramine As with other NSAIDs, concomitant administration of cholestyramine can delay the absorption of naproxen. 16 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda EC-NAPROSYNW (naproxen delayed-release tablets), NAPROSYNW (naproxen tablets), ANAPROX(j/ANAPROX(j DS (naproxen sodium tablets), NAPROSYNW (naproxen suspension) Diuretics Clinical studies, as well as postmarketing observations, have shown that NAPROSYN, EC-NAPROSYN, ANAPROX, ANAPROX DS and NAPROSYN Suspension can reduce the natriuretic effect of furosemide and thiazides in some patients. This response has been attributed to inhibition of renal prostaglandin synthesis. During concomitant therapy with NSAIDs, the patient should be observed closely for signs of renal failure (see WARNINGS: Renal Effects), as well as to assure diuretic efficacy. Lithium NSAIDs have produced an elevation of plasma lithium levels and a reduction in renal lithium clearance. The mean minimum lithium concentration increased 15% and the rcnal clearance was decreased by approximately 20%. These effects have been attributed to inhibition of renal prostaglandin synthesis by the NSAID. Thus, when NSAIDs and lithium are administered concurrently, subjects should be observed carefully for signs of lithium toxicity. Methotrexate NSAIDs have been reported to competitively inhibit methotrexate accumulation in rabbit kidney slices. Naproxen, naproxen sodium and other nonsteroidal anti-inflammatory drugs have been rcported to reduce the tubular secretion of methotrexate in an animal modeL. This may indicate that they could enhance the toxicity of methotrexate. Caution should be used when NSAIDs are administered concomitantly with methotrexate. Warfarin The effects of warfarin and NSAIDs on GI bleeding are synergistic, such that users of both drugs together have a risk of serious GI bleeding higher than users of either drug alone. No significant interactions have been observed in clinical studies with naproxen and coumarin-type anticoagulants. However, caution is advised since interactions have been seen with other nonsteroidal agents of this class. The free fraction of warfarin may increase substantially in some subjects and naproxen interferes with platelet function. Selective Serotonin Reuptake Inhibitors (SSRls) There is an increased risk of gastrointestinal bleeding when selective serotonin reuptake inhibitors (SSRIs) are combined with NSAIDs. Caution should be used when NSAIDs are administed concomintantly with SSRIs. Other Information Concerning Drug Interactions Naproxen is highly bound to plasma albumin; it thus has a theoretical potential for interaction with other albumin-bound drugs such as coumarin- 17 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda EC-NAPROSYNW (naproxen delayed-release tablets), NAPROSYNW (naproxen tablets), ANAPROX(j/ANAPROX(j DS (naproxen sodium tablets), NAPROSYN (naproxen suspension) type anticoagulants, sulphonylureas, hydantoins, othcr NSAIDs, and aspirin. Patients simultaneously receiving naproxen and a hydantoin, sulphonamide or sulphonylurea should be observed for adjustment of dose if required. Naproxen and other nonsteroidal anti-inflammatory drugs can reduce the antihypertensive effect of propranolol and other beta-blockers. Probenecid given concurrently increases naproxen anion plasma levels and extends its plasma half-life significantly. Due to the gastric pH elevating effects of H2-blockers, sucralfate and intensive antacid therapy, concomitant administration of EC-NAPROSYN is not recommended. Drug/Laboratory Test Interaction Naproxen may decrease platelet aggregation and prolong bleeding time. This effect should be kept in mind when bleeding times are determined. The administration of naproxen may result in increased urinary values for 17- ketogenic steroids because of an interaction between the drug and/or its metabolites with m-di-nitrobenzene used in this assay. Although 17-hydroxy- corticosteroid measurements (Porter-Silber test) do not appear to be artifactually altered, it is suggested that therapy with naproxen be temporarily discontinued 72 hours before adrenal function tests are performed if the Porter-Silber test is to be used. Naproxen may interfere with some urinary assays of 5-hydroxy indoleacetic acid (5HIAA). Carcinogenesis A 2-year study was performed in rats to evaluate the carcinogenic potential of naproxen at rat doses of 8, 16, and 24 mg/kg/day (50, 100, and 150 mg/m2). The maximum dose used was 0.28 times the, systemic exposure to humans at the recommended dose. No evidence oftumorigenicity was found. Pregnancy Teratogenic Effects Pregnancy Category C Reproduction studies have been performed in rats at 20 mg/kg/day (125 mg/m2/day, 0.23 times the human systemic exposure), rabbits at 20 mg/kg/day (220 mg/m2/day, 0.27 times the human systemic exposure), and mice at 170 mg/kg/day (510 mg/m2/day, 0.28 times the human systemic exposure) with no evidence of impaired fertility or harm to the fetus due to the drug. However, animal reproduction studies are not always predictive of 18 This label may not be the latest approved by FDA.

There are no adequate and well-controlled studies in pregnant women. NAPROSYN, EC-NAPROSYN, ANAPROX, ANAPROX DS and NAPROSYN Suspension should be used in pregnancy only if the potential benefit justifies the potential risk to the fetus. Nonteratogenic Effects There is some evidence to suggest that when inhibitors of prostaglandin synthesis are us cd to delay preterm labor there is an increased risk of neonatal complications such as necrotizing enterocolitis, patent ductus arteriosus and intracranial hemorrhage. Naproxen treatment given in late pregnancy to delay parturition has been associated with persistent pulmonary hypertension, renal dysfunction and abnormal prostaglandin E levels in preterm infants. Because of the known effects of nonsteroidal anti-inflammatory drugs on the fetal cardiovascular system (closure of ductus arteriosus), use during pregnancy (paricularly late pregnancy) should be avoided. Labor and Delivery In rat studies with NSAIDs, as with other drugs known to inhibit prostaglandin synthesis, an increased incidence of dystocia, delayed parturition, and decreased pup survival occurred. Naproxen-containing products are not recommended in labor and delivery because, through its prostaglandin synthesis inhibitory effect, naproxen may advcrsely affect fetal circulation and inhibit uterine contractions, thus increasing the risk of uterine hemorrhage. The effects of NAPROSYN, EC-NAPROSYN, ANAPROX, ANAPROX DS and NAPROSYN Suspension on labor and delivery in pregnant women are unknown. Nursing Mothers The naproxen anion has been found in the milk of lactating women at a concentration equivalent to approximately 1 % of maximum naproxen concentration in plasma. Because of the possible adverse effects of prostaglandin-inhibiting drugs on neonates, use in nursing mothers should be avoided. Pediatric Use Safety and effectiveness in pediatric patients below the age of 2 years have not been established. Pediatric dosing recommendations for juvenile arthritis are based on well-controlled studies (see DOSAGE- AND ADMINISTRATION). There are no adequate effectiveness or dose-response data for other pediatric conditions, but the experience in juvenile arthritis and other use experience have established that single doses of 2.5 to 5 mg/kg (as naproxen suspension, see DOSAGE AND ADMINISTRATION), with total 19 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda EC-NAPROSYNW (naproxen delayed-release tablets), NAPROSYNW (naproxen tablets), ANAPROX(j/ANAPROX(j DS (naproxen sodium tablets), NAPROSYNW (naproxen suspension) daily dose not exceeding 15 mg/kg/day, are well tolerated in pediatric patients over 2 years of age. Geriatric Use Studies indicate that although total plasma concentration of naproxen is unchanged, the unbound plasma fraction of naproxen is increased in the elderly. Caution is advised when high doses are required and some adjustment of dosage may be required in elderly patients. As with other drugs used in the elderly, it is prudent to use the lowest effective dose. Experience indicates that geriatric paticnts may be particularly sensitive to certain adverse effects of nonsteroidal anti-inflammatory drugs. Elderly or debilitated patients seem to tolerate peptic ulceration or bleeding less well when these events do occur. Most spontaneous reports of fatal GI events are in the geriatric population (see WARNINGS). Naproxen is known to be substantially excreted by the kidney, and the risk of toxic reactions to this drug may be greater in patients with impaired renal function. Because elderly patients are more likely to have decreased renal fuction, care should be taken in dose selection, and it may be useful to monitor renal function. Geriatric patients may be at a greater risk for the development of a form of renal toxicity precipitated by reduced prostaglandin formation during administration of nonsteroidal anti-inflammatory drugs (see WARNINGS: Renal Effects). ADVERSE REACTIONS Adverse reactions reported in controlled clinical trials in 960 patients treated for rheumatoid arthritis or osteoarthritis are listed below. In general, reactions in patients treated chronically were reported 2 to 10 times more frequently than they were in short-term studies in the 962 patients treated for mild to moderate pain or for dysmenorrhea. The most frequent complaints reported related to the gastrointestinal tract. A clinical study found gastrointestinal reactions to be more frequent and more severe in rheumatoid arthritis patients taking daily doses of 1500 mg naproxen compared to those taking 750 mg naproxen (see CLINICAL PHARMACOLOGY). In controlled clinical trials with about 80 pediatric patients and in well- monitored, open-label studies with about 400 pediatric patients with juvenile arthritis treated with naproxen, the incidence of rash and prolonged bleeding times were increased, the incidence of gastrointestinal and central nervous system reactions were about the same, and the incidence of other reactions were lower in pediatric patients than in adults. 20 This label may not be the latest approved by FDA.

Gastrointestinal bleeding can occur. Hypertension, acute renal failure, respiratory depression, and coma may occur, but are rare. Anaphylactoid reactions have been reported with therapeutic ingestion of NSAIDs, and may occur following an overdose. Because naproxen sodium may be rapidly absorbed, high and early blood levels should be anticipated. A few patients have experienced convulsions, but it is not clear whether or not these were drug-related. It is not known what dose of the drug would be life threatening. The oral LDso of the drug is 543 mg/kg in rats, 1234 mg/kg in mice, 4110 mg/kg in hamsters, and greater than 1000 mg/kg in dogs. Treatment Patients should be managed by symptomatic and supportive care following a NSAID overdose. There are no specific antidotes. Hemodialysis does not decrease the plasma concentration of naproxen because of the high degree of its protein binding. Emesis and/or activated charcoal (60 to 100 g in adults, 1 to 2 g/kg in children) and/or osmotic cathartic may be indicated in patients seen within 4 hours of ingestion with symptoms or following a large overdose. Forced diuresis, alkalinization of urine or hemoperfusion may not be useful due to high protein binding. DOSAGE AND ADMINISTRATION Carefully consider the potential benefits and risks of NAPROSYN, EC- NAPROSYN, ANAPROX, ANAPROX DS and NAPROSYN Suspension and other treatment options before dcciding to use NAPROSYN, EC- NAPROSYN, ANAPROX, ANAPROX DS and NAPROSYN Suspension. Use the lowest effectivc dose for the shortest duration consistent with individual patient treatment goals (see WARNINGS). After observing the response to initial therapy with NAPROSYN, EC- NAPROSYN, ANAPROX, ANAPROX DS or NAPROSYN Suspension, the dose and frequency should be adjusted to suit an individual patient's needs, 23 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda EC-NAPROSYNW (naproxen delayed-release tablets), NAPROSYNW (naproxen tablets), ANAPROX(j/ANAPROX(j DS (naproxen sodium tablets), NAPROSYN (naproxen suspension) Different dose strengths and formulations (ie, tablets, suspension) of the drug are not necessarily bioequivalent. This difference should be taken into consideration when changing formulation. Although NAPROSYN, NAPROSYN Suspension, EC-NAPROSYN, ANAPROX and ANAPROX DS all circulate in the plasma as naproxen, they have pharmacokinetic differences that may affect onset of action. Onset of pain relief can begin within 30 minutes in patients taking naproxen sodium and within 1 hour in patients taking naproxen. Because EC-NAPROSYN dissolves in the small intestine rather than in the stomach, the absorption of the drug is delayed compared to the other naproxen formulations (see CLINICAL PHARMACOLOGY). The recommended strategy for initiating therapy is to choose a formulation and a staring dose likely to be effective for the patient and then adjust the dosage based on observation of benefit and/or adverse events. A lower dose should be considered in patients with renal or hepatic impairment or in elderly patients (see WARNINGS and PRECAUTIONS). Geriatric Patients Studies indicate that although total plasma concentration of naproxen is unchanged, . the unbound plasma fraction of naproxen is increased in the eldcrly. Caution is advised when high doses are required and some adjustment of dosage may be required in elderly patients. As with other drugs used in the elderly, it is prudent to use the lowest cffective dose. Patients With Moderate to Severe Renal Impairment Naproxen-containing products are not recommended for use in patients with moderate to severe and severe renal impairment (creatinine clearance ..30 mL/min) (see WARNINGS: Renal Effects). Rheumatoid Arthritis, Osteoarthritis and Ankylosin9 Spondylitis NAPROSYN 250 mg twice daily or 375 mg twice daily or 500 mg twice daily ANAPROX 275 mg (naproxen 250 mg with 25 mg sodium) twice daily ANAPROX DS 550 mg (naproxen 500 mg with 50 mg sodium) twice daily NAPROSYN 250 mg (10 mL/2 tsp) twice daily Suspension or 375 mg (15 mL/3 tsp) twice daily or 500 mg (20 mL/4 tsp) twice daily EC-NAPROSYN 375 mg twice daily or 500 mg twice daily 24 This label may not be the latest approved by FDA.

To maintain the integrity of the enteric coating, the EC-NAPROSYN tablet should not be broken, crushed or chewed during ingestion. NAPROSYN Suspension should be shaken gently before use. During long-term administration, the dose of naproxen may be adjusted up or down depending on the clinical response of the patient. A lower daily dose may suffce for long-term administration. The morning and evening doses do not have to be equal in size and the administration of the drug more frequently than twice daily is not necessary. In patients who tolerate lower doses well, the dose may be increased to naproxen 1500 mg/day for limited periods of up to 6 months when a higher level of anti-inflammatory/analgesic activity is required. When treating such patients with naproxen 1500 mg/day, the physician should observe sufficient increased clinical benefits to offset the potential increased risk. The morning and evening doses do not have to be equal in size and administration of the drug more frequently than twice daily does not generally make a difference in response (see CLINICAL PHARMACOLOGY). Juvenile Arthritis The use of NAPROSYN Suspension is recommended for juvenile arthritis in children 2 years or older because it allows for more flexible dose titration based on the child's weight. In pediatric patients, doses of 5 mg/kg/day produced plasma levels of naproxen similar to those seen in adults taking 500 mg of naproxen (see CLINICAL PHARMACOLOGY). The recommended total daily dose of naproxen is approximately 10 mg/kg given in 2 divided doses (ie, 5 mg/kg given twice a day). A measuring cup marked in 1/2 teaspoon and 2.5 mililiter increments is provided with the NAPROSYN Suspension. The following table may be used as a guide for dosing ofNAPROSYN Suspension: Patient's Weight Dose Administered as 13 kg (29 lb) 62.5 mg bid 2.5 mL (1/2 tsp) twice daily 25 kg (55 lb) 125 mg bid 5.0 mL (1 tsp) twice daily 38 kg (84 lb) 187.5 mg bid 7.5 mL (1 1/2 tsp) twice daily Management of Pain, Primary Dysmenorrhea, and Acute Tendonitis and Bursitis The recommended starting dose is 550 mg of naproxen sodium as ANAPROX/ANAPROX DS followed by 550 mg every 12 hours or 275 mg every 6 to 8 hours as required. The initial total daily dose should not exceed 1375 mg of naproxen sodium. Thereafter, the total daily dose should not 25 This label may not be the latest approved by FDA.

Because the sodium salt of naproxen is more rapidly àbsorbed, ANAPROXIANAPROX DS is recommended for the management of acute painful conditions when prompt onset of pain relief is desired. NAPROSYN may also be used but EC-NAPROSYN is not recommended for initial treatment of acute pain because absorption of naproxen is delayed compared to other naproxen-containing products (see CLINICAL PHARMACOLOGY, INDICATIONS AND USAGE). Acute Gout The recommended starting dose is 750 mg of NAPROSYN followed by 250 mg every 8 hours until the attack has subsided. ANAPROX may also be used at a starting dose of 825 mg followed by 275 mg cvery 8 hours. EC- NAPROSYN is not recommended because of the delay in absorption (see CLINICAL PHARMACOLOGY).

LOMUSTINE - lomustine capsule, gelatin coated NextSource Biotechnology, LLC Lomustine Capsules WARNINGS Lomustine should be administered under the supervision of a qualified physician experienced in the use of cancer chemotherapeutic agents. Bone marrow suppression, notably thrombocytopenia and leukopenia, which may contribute to bleeding and overwhelming infections in an already compromised patient, is the most common and severe of the toxic effects of Lomustine (see WARNINGS and ADVERSE REACTIONS). Since the major toxicity is delayed bone marrow suppression, blood counts should be monitored weekly for at least 6 weeks after a dose (see ADVERSE REACTIONS). At the recommended dosage, courses of Lomustine should not be given more frequently than every 6 weeks. The bone marrow toxicity of Lomustine is cumulative and therefore dosage adjustment must be considered on the basis of nadir blood counts from prior dose (see dosage adjustment table under DOSAGE AND ADMINISTRATION). DESCRIPTION Lomustine (CCNU) is one of the nitrosoureas used in the treatment of certain neoplastic diseases. It is 1-(2-chloro-ethyl)-3­ cyclohexyl-1-nitrosourea. It is a yellow powder with the empirical formula of C9H16ClN3O2 and a molecular weight of 233.71. Lomustine is soluble in 10% ethanol (0.05 mg per mL) and in absolute alcohol (70 mg per mL). Lomustine is relatively insoluble in water (<0.05 mg per mL). It is relatively un-ionized at a physiological pH. Inactive ingredients in Lomustine Capsules are magnesium stearate and mannitol. The structural formula is: Lomustine is available in 10 mg, 40 mg, and 100 mg capsules for oral administration. CLINICAL PHARMACOLOGY Although it is generally agreed that lomustine alkylates DNA and RNA, it is not cross resistant with other alkylators. As with other nitrosoureas, it may also inhibit several key enzymatic processes by carbamoylation of amino acids in proteins. Lomustine may be given orally. Following oral administration of radioactive lomustine at doses ranging from 30 mg/m2 to 100 mg/ m2, about half of the radioactivity given was excreted in the urine in the form of degradation products within 24 hours. The serum half-life of the metabolites ranges from 16 hours to 2 days. Tissue levels are comparable to plasma levels at 15 minutes after intravenous administration. Because of the high lipid solubility and the relative lack of ionization at physiological pH, lomustine crosses the blood-brain barrier quite effectively. Levels of radioactivity in the CSF are 50% or greater than those measured concurrently in plasma. INDICATIONS AND USAGE Lomustine has been shown to be useful as a single agent in addition to other treatment modalities, or in established combination therapy with other approved chemotherapeutic agents in the following: Brain tumors—both primary and metastatic, in patients who have already received appropriate surgical and/or radiotherapeutic procedures. Hodgkin's disease—secondary therapy in combination with other approved drugs in patients who relapse while being treated with primary therapy, or who fail to respond to primary therapy. CONTRAINDICATIONS Lomustine should not be given to individuals who have demonstrated a previous hypersensitivity to it. WARNINGS Since the major toxicity is delayed bone marrow suppression, blood counts should be monitored weekly for at least 6 weeks after a dose (see ADVERSE REACTIONS). At the recommended dosage, courses of Lomustine should not be given more frequently than every 6 weeks. The bone marrow toxicity of Lomustine is cumulative and therefore dosage adjustment must be considered on the basis of nadir blood counts from prior dose (see dosage adjustment table under DOSAGE AND ADMINISTRATION). Pulmonary toxicity from Lomustine appears to be dose related (see ADVERSE REACTIONS). Long-term use of nitrosoureas has been reported to be possibly associated with the development of secondary malignancies. Liver and renal function tests should be monitored periodically (see ADVERSE REACTIONS). page 1 of 5 Reference ID: 3357967 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda Pregnancy Category D Lomustine can cause fetal harm when administered to a pregnant woman. Lomustine is embryotoxic and teratogenic in rats and embryotoxic in rabbits at dose levels equivalent to the human dose. There are no adequate and well controlled studies in pregnant women. If this drug is used during pregnancy, or if the patient becomes pregnant while taking (receiving) this drug, the patient should be apprised of the potential hazard to the fetus. Women of childbearing potential should be advised to avoid becoming pregnant. PRECAUTIONS General In all instances where the use of Lomustine is considered for chemotherapy, the physician must evaluate the need and usefulness of the drug against the risks of toxic effects or adverse reactions. Most such adverse reactions are reversible if detected early. When such effects or reactions do occur, the drug should be reduced in dosage or discontinued and appropriate corrective measures should be taken according to the clinical judgment of the physician. Reinstitution of Lomustine therapy should be carried out with caution and with adequate consideration of the further need for the drug and alertness as to possible recurrence of toxicity. Information for Patients Provide patients with the following information and instructions: 1. In order to provide the proper dose of Lomustine, the dose may be made up of 2 or more different strengths and colors of capsules. Each strength must be dispensed separately by the pharmacist. 2. Lomustine is given as a single oral dose and will not be repeated for at least 6 weeks. Daily use of the recommended dose may lead to toxicities and fatal outcomes. 3. Patients may experience nausea and vomiting that usually last less than 24 hours. Patients may also experience loss of appetite that may last for several days. 4. Instruct patients to contact their physician if they develop any of the following reactions: fever, chills, sore throat, unusual bleeding or bruising, shortness of breath, dry cough, swelling of feet or lower legs, mental confusion, or yellowing of eyes and skin. 5. Instruct patients to wear impervious (rubber or latex) gloves when handling Lomustine Capsules. Laboratory Tests Due to delayed bone marrow suppression, blood counts should be monitored weekly for at least 6 weeks after a dose. Baseline pulmonary function studies should be conducted along with frequent pulmonary function tests during treatment. Patients with a baseline below 70% of the predicted Forced Vital Capacity (FVC) or Carbon Monoxide Diffusing Capacity (DLCO) are particularly at risk. Since Lomustine may cause liver dysfunction, it is recommended that liver function tests be monitored periodically. Renal function tests should also be monitored periodically. Carcinogenesis, Mutagenesis, Impairment of Fertility Lomustine is carcinogenic in rats and mice, producing a marked increase in tumor incidence in doses approximating those employed clinically. Nitrosourea therapy does have carcinogenic potential in humans (see ADVERSE REACTIONS). Lomustine also affects fertility in male rats at doses somewhat higher than the human dose. Pregnancy Pregnancy Category D See WARNINGS. Nursing Mothers It is not known whether this drug is excreted in human milk. Because many drugs are excreted in human milk and because of the potential for serious adverse reactions in nursing infants from Lomustine, a decision should be made whether to discontinue nursing or to discontinue the drug, taking into account the importance of the drug to the mother. Pediatric Use See ADVERSE REACTIONS: Pulmonary Toxicity and DOSAGE AND ADMINISTRATION. Geriatric Use No data from clinical studies of Lomustine are available for patients 65 years of age and over to determine whether they respond differently than younger patients. Other reported clinical experience has not identified differences in responses between elderly and younger patients. In general, dose selection for an elderly patient should be cautious, reflecting the greater frequency of decreased hepatic, renal, or cardiac function and of concomitant disease or other drug therapy. page 2 of 5 Reference ID: 3357967 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda Lomustine and its metabolites are known to be substantially excreted by the kidney, and the risk of toxic reactions to this drug may be greater in patients with impaired renal function. Because elderly patients are more likely to have decreased renal function, care should be taken in dose selection, and renal function should be monitored. ADVERSE REACTIONS Hematologic Toxicity The most frequent and most serious toxicity of Lomustine is delayed myelosuppression. It usually occurs 4 to 6 weeks after drug administration and is dose related. Thrombocytopenia occurs at about 4 weeks postadministration and persists for 1 to 2 weeks. Leukopenia occurs at 5 to 6 weeks after a dose of Lomustine and persists for 1 to 2 weeks. Approximately 65% of patients receiving 130 mg/m2 develop white blood counts below 5000 wbc/mm3. Thirty-six percent developed white blood counts below 3000 wbc/ mm3. Thrombocytopenia is generally more severe than leukopenia. However, both may be dose-limiting toxicities. Lomustine may produce cumulative myelosuppression, manifested by more depressed indices or longer duration of suppression after repeated doses. The occurrence of acute leukemia and bone marrow dysplasias have been reported in patients following long-term nitrosourea therapy. Anemia also occurs, but is less frequent and less severe than thrombocytopenia or leukopenia. Pulmonary Toxicity Pulmonary toxicity characterized by pulmonary infiltrates and/or fibrosis has been reported rarely with Lomustine. Onset of toxicity has occurred after an interval of 6 months or longer from the start of therapy with cumulative doses of Lomustine usually greater than 1100 mg/m2. There is 1 report of pulmonary toxicity at a cumulative dose of only 600 mg. Delayed onset pulmonary fibrosis occurring up to 17 years after treatment has been reported in patients who received related nitrosoureas in childhood and early adolescence (1–16 years) combined with cranial radiotherapy for intracranial tumors. There appeared to be some late reduction of pulmonary function of all long-term survivors. This form of lung fibrosis may be slowly progressive and has resulted in death in some cases. In this long-term study of carmustine, all those initially treated at less than 5 years of age died of delayed pulmonary fibrosis. Gastrointestinal Toxicity Nausea and vomiting may occur 3 to 6 hours after an oral dose and usually last less than 24 hours. Prior administration of antiemetics is effective in diminishing and sometimes preventing this side effect. Nausea and vomiting can also be reduced if Lomustine is administered to fasting patients. Hepatotoxicity A reversible type of hepatic toxicity, manifested by increased transaminase, alkaline phosphatase, and bilirubin levels, has been reported in a small percentage of patients receiving Lomustine. Nephrotoxicity Renal abnormalities consisting of progressive azotemia, decrease in kidney size, and renal failure have been reported in patients who received large cumulative doses after prolonged therapy with Lomustine. Kidney damage has also been reported occasionally in patients receiving lower total doses. Other Toxicities Stomatitis, alopecia, optic atrophy, and visual disturbances, such as blindness, have been reported infrequently. Neurological reactions, such as disorientation, lethargy, ataxia, and dysarthria have been noted in some patients receiving Lomustine. However, the relationship to medication in these patients is unclear. OVERDOSAGE Accidental overdose with lomustine has been reported, including fatal cases. Accidental overdose has been associated with bone marrow suppression, abdominal pain, diarrhea, vomiting, anorexia, lethargy, dizziness, abnormal hepatic function, cough, and shortness of breath. No proven antidotes have been established for Lomustine overdosage. In case of overdose, appropriate supportive measures should be taken. DOSAGE AND ADMINISTRATION The recommended dose of Lomustine in adult and pediatric patients as a single agent in previously untreated patients is 130 mg/m2 as a single oral dose every 6 weeks (see PRECAUTIONS: Information for Patients and HOW SUPPLIED: Directions to the Pharmacist). In individuals with compromised bone marrow function, the dose should be reduced to 100 mg/m2 every 6 weeks. When Lomustine is used in combination with other myelosuppressive drugs, the doses should be adjusted accordingly. All doses of Lomustine must be rounded to the nearest 10 mg by the prescriber (see HOW SUPPLIED). page 3 of 5 Reference ID: 3357967 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda Doses subsequent to the initial dose should be adjusted according to the hematologic response of the patient to the preceding dose. The following schedule is suggested as a guide to dosage adjustment: Nadir After Prior Dose Percentage of Prior Dose to be Given Leukocytes (/mm3) Platelets (/mm3) ≥4000 3000–3999 2000–2999 <2000 ≥100,000 75,000–99,999 25,000–74,999 <25,000 100% 100% 70% 50% A repeat course of Lomustine should not be given until circulating blood elements have returned to acceptable levels (platelets above 100,000/mm3; leukocytes above 4000/mm3), and this is usually in 6 weeks. Adequate number of neutrophils should be present on a peripheral blood smear. Blood counts should be monitored weekly and repeat courses should not be given before 6 weeks because the hematologic toxicity is delayed and cumulative. HOW SUPPLIED Lomustine Capsules are available in individual bottles of 5 capsules each. NDC 58181-3032-5 100 mg capsules (Green/Green) NDC 58181-3031-5 40 mg capsules (White/Green) NDC 58181-3030-5 10 mg capsules (White/White) Stability Lomustine Capsules are stable for the lot life indicated on package labeling when stored in well-closed containers at 25°C (77°F); excursions permitted to 15°C–30°C (59°F–86°F) [see USP Controlled Room Temperature].

Directions to the Pharmacist Confirm the total dose prescribed by the physician can be obtained by determining the appropriate combination of capsule strengths. Only the appropriate number of Lomustine capsules required for the administration of a single dose should be dispensed. In order to provide the proper dose of Lomustine, patients should be aware that the prescribed dose may be made up of 2 or more different strengths and colors of capsules and that each strength must be dispensed separately. Inform patients that Lomustine is taken as a single oral dose and will not be repeated for at least 6 weeks. Daily use of the recommended dose may lead to toxicities and fatal outcomes. Caution should be exercised when handling Lomustine Capsules. Procedures for proper handling and disposal of anticancer drugs should be utilized. Several guidelines on this subject have been published.1-4 To minimize the risk of dermal exposure, always wear impervious gloves when handling bottles containing Lomustine Capsules.

The different 63 dosage forms of NAPROSYN are bioequivalent in terms of extent of 64 absorption (AUC) and peak concentration (Cmax); however, the products do 65 differ in their pattern of absorption. These differences between naproxen 66 products are related to both the chemical form of naproxen used and its 67 formulation. Even with the observed differences in pattern of absorption, the 68 elimination half-life of naproxen is unchanged across products ranging from 69 12 to 17 hours. Steady-state levels of naproxen are reached in 4 to 5 days, and 70 the degree of naproxen accumulation is consistent with this half-life. This 71 suggests that the differences in pattern of release play only a negligible role in 72 the attainment of steady-state plasma levels. 73 Absorption 74 Immediate Release 75 After administration of NAPROSYN tablets, peak plasma levels are attained 76 in 2 to 4 hours. After oral administration of ANAPROX, peak plasma levels 77 are attained in 1 to 2 hours. The difference in rates between the two products 78 is due to the increased aqueous solubility of the sodium salt of naproxen used 79 in ANAPROX. Peak plasma levels of naproxen given as NAPROSYN 80 Suspension are attained in 1 to 4 hours. 81 Delayed Release 82 EC-NAPROSYN is designed with a pH-sensitive coating to provide a barrier 83 to disintegration in the acidic environment of the stomach and to lose integrity 84 in the more neutral environment of the small intestine. The enteric polymer 85 coating selected for EC-NAPROSYN dissolves above pH 6. When EC­ 86 NAPROSYN was given to fasted subjects, peak plasma levels were attained 87 about 4 to 6 hours following the first dose (range: 2 to 12 hours). An in vivo 88 study in man using radiolabeled EC-NAPROSYN tablets demonstrated that 89 EC-NAPROSYN dissolves primarily in the small intestine rather than in the 90 stomach, so the absorption of the drug is delayed until the stomach is emptied. 91 When EC-NAPROSYN and NAPROSYN were given to fasted subjects 92 (n=24) in a crossover study following 1 week of dosing, differences in time to 93 peak plasma levels (Tmax) were observed, but there were no differences in total 94 absorption as measured by Cmax and AUC: 3 This label may not be the latest approved by FDA.

The presence of food prolonged the time the tablets remained in 106 the stomach, time to first detectable serum naproxen levels, and time to 107 maximal naproxen levels (Tmax), but did not affect peak naproxen levels 108 (Cmax). 109 Distribution 110 Naproxen has a volume of distribution of 0.16 L/kg. At therapeutic levels 111 naproxen is greater than 99% albumin-bound. At doses of naproxen greater 112 than 500 mg/day there is less than proportional increase in plasma levels due 113 to an increase in clearance caused by saturation of plasma protein binding at 114 higher doses (average trough Css 36.5, 49.2 and 56.4 mg/L with 500, 1000 and 115 1500 mg daily doses of naproxen, respectively). The naproxen anion has been 116 found in the milk of lactating women at a concentration equivalent to 117 approximately 1% of maximum naproxen concentration in plasma (see 118 PRECAUTIONS: Nursing Mothers). 119 Metabolism 120 Naproxen is extensively metabolized in the liver to 6-0-desmethyl naproxen, 121 and both parent and metabolites do not induce metabolizing enzymes. Both 122 naproxen and 6-0-desmethyl naproxen are further metabolized to their 123 respective acylglucuronide conjugated metabolites. 124 Excretion 125 The clearance of naproxen is 0.13 mL/min/kg. Approximately 95% of the 126 naproxen from any dose is excreted in the urine, primarily as naproxen (<1%), 127 6-0-desmethyl naproxen (<1%) or their conjugates (66% to 92%). The plasma 4 This label may not be the latest approved by FDA.

The 129 corresponding half-lives of both naproxen’s metabolites and conjugates are 130 shorter than 12 hours, and their rates of excretion have been found to coincide 131 closely with the rate of naproxen disappearance from the plasma. Small 132 amounts, 3% or less of the administered dose, are excreted in the feces. In 133 patients with renal failure metabolites may accumulate (see WARNINGS: 134 Renal Effects). 135 Special Populations 136 Pediatric Patients 137 In pediatric patients aged 5 to 16 years with arthritis, plasma naproxen levels 138 following a 5 mg/kg single dose of naproxen suspension (see DOSAGE AND 139 ADMINISTRATION) were found to be similar to those found in normal 140 adults following a 500 mg dose. The terminal half-life appears to be similar in 141 pediatric and adult patients. Pharmacokinetic studies of naproxen were not 142 performed in pediatric patients younger than 5 years of age. Pharmacokinetic 143 parameters appear to be similar following administration of naproxen 144 suspension or tablets in pediatric patients. EC-NAPROSYN has not been 145 studied in subjects under the age of 18. 146 Geriatric Patients 147 Studies indicate that although total plasma concentration of naproxen is 148 unchanged, the unbound plasma fraction of naproxen is increased in the 149 elderly, although the unbound fraction is <1% of the total naproxen 150 concentration. Unbound trough naproxen concentrations in elderly subjects 151 have been reported to range from 0.12% to 0.19% of total naproxen 152 concentration, compared with 0.05% to 0.075% in younger subjects. The 153 clinical significance of this finding is unclear, although it is possible that the 154 increase in free naproxen concentration could be associated with an increase 155 in the rate of adverse events per a given dosage in some elderly patients. 156 Race 157 Pharmacokinetic differences due to race have not been studied. 158 Hepatic Insufficiency 159 Naproxen pharmacokinetics has not been determined in subjects with hepatic 160 insufficiency. 161 Renal Insufficiency 162 Naproxen pharmacokinetics has not been determined in subjects with renal 163 insufficiency. Given that naproxen, its metabolites and conjugates are 164 primarily excreted by the kidney, the potential exists for naproxen metabolites 5 This label may not be the latest approved by FDA.

Elimination of naproxen 166 is decreased in patients with severe renal impairment. Naproxen-containing 167 products are not recommended for use in patients with moderate to severe and 168 severe renal impairment (creatinine clearance <30 mL/min) (see 169 WARNINGS: Renal Effects). 170 CLINICAL STUDIES 171 General Information 172 Naproxen has been studied in patients with rheumatoid arthritis, osteoarthritis, 173 juvenile arthritis, ankylosing spondylitis, tendonitis and bursitis, and acute 174 gout. Improvement in patients treated for rheumatoid arthritis was 175 demonstrated by a reduction in joint swelling, a reduction in duration of 176 morning stiffness, a reduction in disease activity as assessed by both the 177 investigator and patient, and by increased mobility as demonstrated by a 178 reduction in walking time. Generally, response to naproxen has not been 179 found to be dependent on age, sex, severity or duration of rheumatoid arthritis. 180 In patients with osteoarthritis, the therapeutic action of naproxen has been 181 shown by a reduction in joint pain or tenderness, an increase in range of 182 motion in knee joints, increased mobility as demonstrated by a reduction in 183 walking time, and improvement in capacity to perform activities of daily 184 living impaired by the disease. 185 In a clinical trial comparing standard formulations of naproxen 375 mg bid 186 (750 mg a day) vs 750 mg bid (1500 mg/day), 9 patients in the 750 mg group 187 terminated prematurely because of adverse events. Nineteen patients in the 188 1500 mg group terminated prematurely because of adverse events. Most of 189 these adverse events were gastrointestinal events. 190 In clinical studies in patients with rheumatoid arthritis, osteoarthritis, and 191 juvenile arthritis, naproxen has been shown to be comparable to aspirin and 192 indomethacin in controlling the aforementioned measures of disease activity, 193 but the frequency and severity of the milder gastrointestinal adverse effects 194 (nausea, dyspepsia, heartburn) and nervous system adverse effects (tinnitus, 195 dizziness, lightheadedness) were less in naproxen-treated patients than in 196 those treated with aspirin or indomethacin. 197 In patients with ankylosing spondylitis, naproxen has been shown to decrease 198 night pain, morning stiffness and pain at rest. In double-blind studies the drug 199 was shown to be as effective as aspirin, but with fewer side effects. 200 In patients with acute gout, a favorable response to naproxen was shown by 201 significant clearing of inflammatory changes (eg, decrease in swelling, heat) 202 within 24 to 48 hours, as well as by relief of pain and tenderness. 6 This label may not be the latest approved by FDA.

Onset of pain relief can begin within 1 hour in 206 patients taking naproxen and within 30 minutes in patients taking naproxen 207 sodium. Analgesic effect was shown by such measures as reduction of pain 208 intensity scores, increase in pain relief scores, decrease in numbers of patients 209 requiring additional analgesic medication, and delay in time to remedication. 210 The analgesic effect has been found to last for up to 12 hours. 211 Naproxen may be used safely in combination with gold salts and/or 212 corticosteroids; however, in controlled clinical trials, when added to the 213 regimen of patients receiving corticosteroids, it did not appear to cause greater 214 improvement over that seen with corticosteroids alone. Whether naproxen has 215 a “steroid-sparing” effect has not been adequately studied. When added to the 216 regimen of patients receiving gold salts, naproxen did result in greater 217 improvement. Its use in combination with salicylates is not recommended 218 because there is evidence that aspirin increases the rate of excretion of 219 naproxen and data are inadequate to demonstrate that naproxen and aspirin 220 produce greater improvement over that achieved with aspirin alone. In 221 addition, as with other NSAIDs, the combination may result in higher 222 frequency of adverse events than demonstrated for either product alone. 223 In 51Cr blood loss and gastroscopy studies with normal volunteers, daily 224 administration of 1000 mg of naproxen as 1000 mg of NAPROSYN 225 (naproxen) or 1100 mg of ANAPROX (naproxen sodium) has been 226 demonstrated to cause statistically significantly less gastric bleeding and 227 erosion than 3250 mg of aspirin. 228 Three 6-week, double-blind, multicenter studies with EC-NAPROSYN 229 (naproxen) (375 or 500 mg bid, n=385) and NAPROSYN (375 or 500 mg bid, 230 n=279) were conducted comparing EC-NAPROSYN with NAPROSYN, 231 including 355 rheumatoid arthritis and osteoarthritis patients who had a recent 232 history of NSAID-related GI symptoms. These studies indicated that EC­ 233 NAPROSYN and NAPROSYN showed no significant differences in efficacy 234 or safety and had similar prevalence of minor GI complaints. Individual 235 patients, however, may find one formulation preferable to the other. 236 Five hundred and fifty-three patients received EC-NAPROSYN during long­ 237 term open-label trials (mean length of treatment was 159 days). The rates for 238 clinically-diagnosed peptic ulcers and GI bleeds were similar to what has been 239 historically reported for long-term NSAID use. 240 Geriatric Patients 241 The hepatic and renal tolerability of long-term naproxen administration was 242 studied in two double-blind clinical trials involving 586 patients.

Naproxen was administered at doses of 375 mg twice 245 daily or 750 mg twice daily for up to 6 months. Transient abnormalities of 246 laboratory tests assessing hepatic and renal function were noted in some 247 patients, although there were no differences noted in the occurrence of 248 abnormal values among different age groups. 249 INDICATIONS AND USAGE 250 Carefully consider the potential benefits and risks of NAPROSYN, EC­ 251 NAPROSYN, ANAPROX, ANAPROX DS or NAPROSYN Suspension and 252 other treatment options before deciding to use NAPROSYN, EC­ 253 NAPROSYN, ANAPROX, ANAPROX DS or NAPROSYN Suspension. Use 254 the lowest effective dose for the shortest duration consistent with individual 255 patient treatment goals (see WARNINGS). 256 Naproxen as NAPROSYN, EC-NAPROSYN, ANAPROX, ANAPROX DS or 257 NAPROSYN Suspension is indicated: 258 • For the relief of the signs and symptoms of rheumatoid arthritis 259 • For the relief of the signs and symptoms of osteoarthritis 260 • For the relief of the signs and symptoms of ankylosing spondylitis 261 • For the relief of the signs and symptoms of juvenile arthritis 262 Naproxen as NAPROSYN Suspension is recommended for juvenile 263 rheumatoid arthritis in order to obtain the maximum dosage flexibility based 264 on the patient’s weight. 265 Naproxen as NAPROSYN, ANAPROX, ANAPROX DS and NAPROSYN 266 Suspension is also indicated: 267 • For relief of the signs and symptoms of tendonitis 268 • For relief of the signs and symptoms of bursitis 269 • For relief of the signs and symptoms of acute gout 270 • For the management of pain 271 • For the management of primary dysmenorrhea 272 EC-NAPROSYN is not recommended for initial treatment of acute pain 273 because the absorption of naproxen is delayed compared to absorption from 274 other naproxen-containing products (see CLINICAL PHARMACOLOGY 275 and DOSAGE AND ADMINISTRATION). 8 This label may not be the latest approved by FDA.

Severe, rarely fatal, anaphylactic-like reactions to NSAIDs 284 have been reported in such patients (see WARNINGS: Anaphylactoid 285 Reactions and PRECAUTIONS: Preexisting Asthma). 286 NAPROSYN, EC-NAPROSYN, ANAPROX, ANAPROX DS and 287 NAPROSYN Suspension are contraindicated for the treatment of peri­ 288 operative pain in the setting of coronary artery bypass graft (CABG) surgery 289 (see WARNINGS). 290 WARNINGS 291 CARDIOVASCULAR EFFECTS 292 Cardiovascular Thrombotic Events 293 Clinical trials of several COX-2 selective and nonselective NSAIDs of up to 294 three years duration have shown an increased risk of serious cardiovascular 295 (CV) thrombotic events, myocardial infarction, and stroke, which can be fatal. 296 All NSAIDs, both COX-2 selective and nonselective, may have a similar risk. 297 Patients with known CV disease or risk factors for CV disease may be at 298 greater risk. To minimize the potential risk for an adverse CV event in patients 299 treated with an NSAID, the lowest effective dose should be used for the 300 shortest duration possible. Physicians and patients should remain alert for the 301 development of such events, even in the absence of previous CV symptoms. 302 Patients should be informed about the signs and/or symptoms of serious CV 303 events and the steps to take if they occur. 304 There is no consistent evidence that concurrent use of aspirin mitigates the 305 increased risk of serious CV thrombotic events associated with NSAID use. 306 The concurrent use of aspirin and an NSAID does increase the risk of serious 307 GI events (see Gastrointestinal Effects – Risk of Ulceration, Bleeding, and 308 Perforation). 309 Two large, controlled, clinical trials of a COX-2 selective NSAID for the 310 treatment of pain in the first 10-14 days following CABG surgery found an 311 increased incidence of myocardial infarction and stroke (see 312 CONTRAINDICATIONS). 9 This label may not be the latest approved by FDA.

Patients taking thiazides or 318 loop diuretics may have impaired response to these therapies when taking 319 NSAIDs. NSAIDs, including NAPROSYN, EC-NAPROSYN, ANAPROX, 320 ANAPROX DS and NAPROSYN Suspension, should be used with caution in 321 patients with hypertension. Blood pressure (BP) should be monitored closely 322 during the initiation of NSAID treatment and throughout the course of 323 therapy. 324 Congestive Heart Failure and Edema 325 Fluid retention, edema, and peripheral edema have been observed in some 326 patients taking NSAIDs. NAPROSYN, EC-NAPROSYN, ANAPROX, 327 ANAPROX DS and NAPROSYN Suspension should be used with caution in 328 patients with fluid retention, hypertension, or heart failure. Since each 329 ANAPROX or ANAPROX DS tablet contains 25 mg or 50 mg of sodium 330 (about 1 mEq per each 250 mg of naproxen), and each teaspoonful of 331 NAPROSYN Suspension contains 39 mg (about 1.5 mEq per each 125 mg of 332 naproxen) of sodium, this should be considered in patients whose overall 333 intake of sodium must be severely restricted. 334 Gastrointestinal Effects – Risk of Ulceration, Bleeding, and 335 Perforation 336 NSAIDs, including NAPROSYN, EC-NAPROSYN, ANAPROX, 337 ANAPROX DS and NAPROSYN Suspension, can cause serious 338 gastrointestinal (GI) adverse events including inflammation, bleeding, 339 ulceration, and perforation of the stomach, small intestine, or large intestine, 340 which can be fatal. 341 These serious adverse events can occur at any time, with or without warning 342 symptoms, in patients treated with NSAIDs. Only one in five patients, who 343 develop a serious upper GI adverse event on NSAID therapy, is symptomatic. 344 Upper GI ulcers, gross bleeding, or perforation caused by NSAIDs occur in 345 approximately 1% of patients treated for 3-6 months, and in about 2-4% of 346 patients treated for one year. These trends continue with longer duration of 347 use, increasing the likelihood of developing a serious GI event at some time 348 during the course of therapy. However, even short-term therapy is not without 349 risk. The utility of periodic laboratory monitoring has not been demonstrated, 350 nor has it been adequately assessed. Only 1 in 5 patients who develop a 351 serious upper GI adverse event on NSAID therapy is symptomatic. 10 This label may not be the latest approved by FDA.

Patients with a prior 354 history of peptic ulcer disease and/or gastrointestinal bleeding who use 355 NSAIDs have a greater than 10-fold increased risk for developing a GI bleed 356 compared to patients with neither of these risk factors. Other factors that 357 increase the risk for GI bleeding in patients treated with NSAIDs include 358 concomitant use of oral corticosteroids or anticoagulants, longer duration of 359 NSAID therapy, smoking, use of alcohol, older age, and poor general health 360 status. Most spontaneous reports of fatal GI events are in elderly or debilitated 361 patients and therefore, special care should be taken in treating this population. 362 To minimize the potential risk for an adverse GI event in patients treated with 363 an NSAID, the lowest effective dose should be used for the shortest possible 364 duration. Patients and physicians should remain alert for signs and symptoms 365 of GI ulceration and bleeding during NSAID therapy and promptly initiate 366 additional evaluation and treatment if a serious GI adverse event is suspected. 367 This should include discontinuation of the NSAID until a serious GI adverse 368 event is ruled out. For high risk patients, alternate therapies that do not 369 involve NSAIDs should be considered. 370 Epidemiological studies, both of the case-control and cohort design, have 371 demonstrated an association between use of psychotropic drugs that interfere 372 with serotonin reuptake and the occurrence of upper gastrointestinal bleeding. 373 In two studies, concurrent use of an NSAID or aspirin potentiated the risk of 374 bleeding (see PRECAUTIONS: Drug Interactions). Although these studies 375 focused on upper gastrointestinal bleeding, there is reason to believe that 376 bleeding at other sites may be similarly potentiated. 377 NSAIDs should be given with care to patients with a history of inflammatory 378 bowel disease (ulcerative colitis, Crohn’s disease) as their condition may be 379 exacerbated. 380 Renal Effects 381 Long-term administration of NSAIDs has resulted in renal papillary necrosis 382 and other renal injury. Renal toxicity has also been seen in patients in whom 383 renal prostaglandins have a compensatory role in the maintenance of renal 384 perfusion. In these patients, administration of a nonsteroidal 385 anti-inflammatory drug may cause a dose-dependent reduction in 386 prostaglandin formation and, secondarily, in renal blood flow, which may 387 precipitate overt renal decompensation. Patients at greatest risk of this 388 reaction are those with impaired renal function, hypovolemia, heart failure, 389 liver dysfunction, salt depletion, those taking diuretics and ACE inhibitors, 390 and the elderly. Discontinuation of nonsteroidal anti-inflammatory drug 391 therapy is usually followed by recovery to the pretreatment state (see 392 WARNINGS: Advanced Renal Disease). 11 This label may not be the latest approved by FDA.

Therefore, 397 treatment with NAPROSYN, EC-NAPROSYN, ANAPROX, ANAPROX DS 398 and NAPROSYN Suspension is not recommended in these patients with 399 advanced renal disease. If NAPROSYN, EC-NAPROSYN, ANAPROX, 400 ANAPROX DS or NAPROSYN Suspension therapy must be initiated, close 401 monitoring of the patient’s renal function is advisable. 402 Anaphylactoid Reactions 403 As with other NSAIDs, anaphylactoid reactions may occur in patients without 404 known prior exposure to NAPROSYN, EC-NAPROSYN, ANAPROX, 405 ANAPROX DS or NAPROSYN Suspension. NAPROSYN, EC­ 406 NAPROSYN, ANAPROX, ANAPROX DS and NAPROSYN Suspension 407 should not be given to patients with the aspirin triad. This symptom complex 408 typically occurs in asthmatic patients who experience rhinitis with or without 409 nasal polyps, or who exhibit severe, potentially fatal bronchospasm after 410 taking aspirin or other NSAIDs (see CONTRAINDICATIONS and 411 PRECAUTIONS: Preexisting Asthma). Emergency help should be sought 412 in cases where an anaphylactoid reaction occurs. Anaphylactoid reactions, like 413 anaphylaxis, may have a fatal outcome. 414 Skin Reactions 415 NSAIDs, including NAPROSYN, EC-NAPROSYN, ANAPROX, 416 ANAPROX DS and NAPROSYN Suspension, can cause serious skin adverse 417 events such as exfoliative dermatitis, Stevens-Johnson Syndrome (SJS), and 418 toxic epidermal necrolysis (TEN), which can be fatal. These serious events 419 may occur without warning. Patients should be informed about the signs and 420 symptoms of serious skin manifestations and use of the drug should be 421 discontinued at the first appearance of skin rash or any other sign of 422 hypersensitivity. 423 Pregnancy 424 In late pregnancy, as with other NSAIDs, NAPROSYN, EC-NAPROSYN, 425 ANAPROX, ANAPROX DS and NAPROSYN Suspension should be avoided 426 because it may cause premature closure of the ductus arteriosus. 427 PRECAUTIONS 428 General 429 Naproxen-containing products such as NAPROSYN, EC-NAPROSYN, 430 ANAPROX, ANAPROX DS, NAPROSYN SUSPENSION, ALEVE®, and 12 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda EC-NAPROSYN® (naproxen delayed-release tablets), NAPROSYN® (naproxen tablets), ANAPROX®/ANAPROX® DS (naproxen sodium tablets), NAPROSYN® (naproxen suspension) 431 other naproxen products should not be used concomitantly since they all 432 circulate in the plasma as the naproxen anion. 433 NAPROSYN, EC-NAPROSYN, ANAPROX, ANAPROX DS and 434 NAPROSYN Suspension cannot be expected to substitute for corticosteroids 435 or to treat corticosteroid insufficiency. Abrupt discontinuation of 436 corticosteroids may lead to disease exacerbation. Patients on prolonged 437 corticosteroid therapy should have their therapy tapered slowly if a decision is 438 made to discontinue corticosteroids and the patient should be observed closely 439 for any evidence of adverse effects, including adrenal insufficiency and 440 exacerbation of symptoms of arthritis. 441 Patients with initial hemoglobin values of 10 g or less who are to receive long­ 442 term therapy should have hemoglobin values determined periodically. 443 The pharmacological activity of NAPROSYN, EC-NAPROSYN, 444 ANAPROX, ANAPROX DS and NAPROSYN Suspension in reducing fever 445 and inflammation may diminish the utility of these diagnostic signs in 446 detecting complications of presumed noninfectious, noninflammatory painful 447 conditions. 448 Because of adverse eye findings in animal studies with drugs of this class, it is 449 recommended that ophthalmic studies be carried out if any change or 450 disturbance in vision occurs. 451 Hepatic Effects 452 Borderline elevations of one or more liver tests may occur in up to 15% of 453 patients taking NSAIDs including NAPROSYN, EC-NAPROSYN, 454 ANAPROX, ANAPROX DS and NAPROSYN Suspension. Hepatic 455 abnormalities may be the result of hypersensitivity rather than direct toxicity. 456 These laboratory abnormalities may progress, may remain essentially 457 unchanged, or may be transient with continued therapy. The SGPT (ALT) test 458 is probably the most sensitive indicator of liver dysfunction. Notable 459 elevations of ALT or AST (approximately three or more times the upper limit 460 of normal) have been reported in approximately 1% of patients in clinical 461 trials with NSAIDs. In addition, rare cases of severe hepatic reactions, 462 including jaundice and fatal fulminant hepatitis, liver necrosis and hepatic 463 failure, some of them with fatal outcomes have been reported. 464 A patient with symptoms and/or signs suggesting liver dysfunction, or in 465 whom an abnormal liver test has occurred, should be evaluated for evidence 466 of the development of more severe hepatic reaction while on therapy with 467 NAPROSYN, EC-NAPROSYN, ANAPROX, ANAPROX DS or 468 NAPROSYN Suspension. 13 This label may not be the latest approved by FDA.

It is prudent to use the lowest 478 effective dose. 479 Hematological Effects 480 Anemia is sometimes seen in patients receiving NSAIDs, including 481 NAPROSYN, EC-NAPROSYN, ANAPROX, ANAPROX DS and 482 NAPROSYN Suspension. This may be due to fluid retention, occult or gross 483 GI blood loss, or an incompletely described effect upon erythropoiesis. 484 Patients on long-term treatment with NSAIDs, including NAPROSYN, EC­ 485 NAPROSYN, ANAPROX, ANAPROX DS and NAPROSYN Suspension, 486 should have their hemoglobin or hematocrit checked if they exhibit any signs 487 or symptoms of anemia. 488 NSAIDs inhibit platelet aggregation and have been shown to prolong bleeding 489 time in some patients. Unlike aspirin, their effect on platelet function is 490 quantitatively less, of shorter duration, and reversible. Patients receiving either 491 NAPROSYN, EC-NAPROSYN, ANAPROX, ANAPROX DS or 492 NAPROSYN Suspension who may be adversely affected by alterations in 493 platelet function, such as those with coagulation disorders or patients 494 receiving anticoagulants, should be carefully monitored. 495 Preexisting Asthma 496 Patients with asthma may have aspirin-sensitive asthma. The use of aspirin in 497 patients with aspirin-sensitive asthma has been associated with severe 498 bronchospasm, which can be fatal. Since cross reactivity, including 499 bronchospasm, between aspirin and other nonsteroidal anti-inflammatory 500 drugs has been reported in such aspirin-sensitive patients, NAPROSYN, EC­ 501 NAPROSYN, ANAPROX, ANAPROX DS and NAPROSYN Suspension 502 should not be administered to patients with this form of aspirin sensitivity and 503 should be used with caution in patients with preexisting asthma. 504 Information for Patients 505 Patients should be informed of the following information before initiating 506 therapy with an NSAID and periodically during the course of ongoing 14 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda EC-NAPROSYN® (naproxen delayed-release tablets), NAPROSYN® (naproxen tablets), ANAPROX®/ANAPROX® DS (naproxen sodium tablets), NAPROSYN® (naproxen suspension) 507 therapy. Patients should also be encouraged to read the NSAID 508 Medication Guide that accompanies each prescription dispensed. 509 1. NAPROSYN, EC-NAPROSYN, ANAPROX, ANAPROX DS and 510 NAPROSYN Suspension, like other NSAIDs, may cause serious CV side 511 effects, such as MI or stroke, which may result in hospitalization and even 512 death. Although serious CV events can occur without warning symptoms, 513 patients should be alert for the signs and symptoms of chest pain, 514 shortness of breath, weakness, slurring of speech, and should ask for 515 medical advice when observing any indicative sign or symptoms. Patients 516 should be apprised of the importance of this follow-up (see WARNINGS: 517 Cardiovascular Effects). 518 2. NAPROSYN, EC-NAPROSYN, ANAPROX, ANAPROX DS and 519 NAPROSYN Suspension, like other NSAIDs, can cause GI discomfort 520 and, rarely, serious GI side effects, such as ulcers and bleeding, which 521 may result in hospitalization and even death. Although serious GI tract 522 ulcerations and bleeding can occur without warning symptoms, patients 523 should be alert for the signs and symptoms of ulcerations and bleeding, 524 and should ask for medical advice when observing any indicative sign or 525 symptoms including epigastric pain, dyspepsia, melena, and hematemesis. 526 Patients should be apprised of the importance of this follow-up (see 527 WARNINGS: Gastrointestinal Effects: Risk of Ulceration, Bleeding, 528 and Perforation). 529 3. NAPROSYN, EC-NAPROSYN, ANAPROX, ANAPROX DS and 530 NAPROSYN Suspension, like other NSAIDs, can cause serious skin side 531 effects such as exfoliative dermatitis, SJS, and TEN, which may result in 532 hospitalizations and even death. Although serious skin reactions may 533 occur without warning, patients should be alert for the signs and 534 symptoms of skin rash and blisters, fever, or other signs of 535 hypersensitivity such as itching, and should ask for medical advice when 536 observing any indicative signs or symptoms. Patients should be advised to 537 stop the drug immediately if they develop any type of rash and contact 538 their physicians as soon as possible. 539 4. Patients should promptly report signs or symptoms of unexplained weight 540 gain or edema to their physicians. 541 5. Patients should be informed of the warning signs and symptoms of 542 hepatotoxicity (eg, nausea, fatigue, lethargy, pruritus, jaundice, right upper 543 quadrant tenderness, and “flu-like” symptoms). If these occur, patients 544 should be instructed to stop therapy and seek immediate medical therapy. 545 6. Patients should be informed of the signs of an anaphylactoid reaction (eg, 546 difficulty breathing, swelling of the face or throat). If these occur, patients 547 should be instructed to seek immediate emergency help (see 548 WARNINGS). 15 This label may not be the latest approved by FDA.

In late pregnancy, as with other NSAIDs, NAPROSYN, EC-NAPROSYN, 550 ANAPROX, ANAPROX DS and NAPROSYN Suspension should be 551 avoided because it may cause premature closure of the ductus arteriosus. 552 8. Caution should be exercised by patients whose activities require alertness 553 if they experience drowsiness, dizziness, vertigo or depression during 554 therapy with naproxen. 555 Laboratory Tests 556 Because serious GI tract ulcerations and bleeding can occur without warning 557 symptoms, physicians should monitor for signs or symptoms of GI bleeding. 558 Patients on long-term treatment with NSAIDs should have their CBC and a 559 chemistry profile checked periodically. If clinical signs and symptoms 560 consistent with liver or renal disease develop, systemic manifestations occur 561 (eg, eosinophilia, rash, etc.) or if abnormal liver tests persist or worsen, 562 NAPROSYN, EC-NAPROSYN, ANAPROX, ANAPROX DS and 563 NAPROSYN Suspension should be discontinued. 564 Drug Interactions 565 ACE-inhibitors 566 Reports suggest that NSAIDs may diminish the antihypertensive effect of 567 ACE-inhibitors. This interaction should be given consideration in patients 568 taking NSAIDs concomitantly with ACE-inhibitors. 569 Antacids and Sucralfate 570 Concomitant administration of some antacids (magnesium oxide or aluminum 571 hydroxide) and sucralfate can delay the absorption of naproxen. 572 Aspirin 573 When naproxen as NAPROSYN, EC-NAPROSYN, ANAPROX, ANAPROX 574 DS or NAPROSYN Suspension is administered with aspirin, its protein 575 binding is reduced, although the clearance of free NAPROSYN, EC­ 576 NAPROSYN, ANAPROX, ANAPROX DS or NAPROSYN Suspension is 577 not altered. The clinical significance of this interaction is not known; 578 however, as with other NSAIDs, concomitant administration of naproxen and 579 naproxen sodium and aspirin is not generally recommended because of the 580 potential of increased adverse effects. 581 Cholestyramine 582 As with other NSAIDs, concomitant administration of cholestyramine can 583 delay the absorption of naproxen. 16 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda EC-NAPROSYN® (naproxen delayed-release tablets), NAPROSYN® (naproxen tablets), ANAPROX®/ANAPROX® DS (naproxen sodium tablets), NAPROSYN® (naproxen suspension) 584 Diuretics 585 Clinical studies, as well as postmarketing observations, have shown that 586 NAPROSYN, EC-NAPROSYN, ANAPROX, ANAPROX DS and 587 NAPROSYN Suspension can reduce the natriuretic effect of furosemide and 588 thiazides in some patients. This response has been attributed to inhibition of 589 renal prostaglandin synthesis. During concomitant therapy with NSAIDs, the 590 patient should be observed closely for signs of renal failure (see 591 WARNINGS: Renal Effects), as well as to assure diuretic efficacy. 592 Lithium 593 NSAIDs have produced an elevation of plasma lithium levels and a reduction 594 in renal lithium clearance. The mean minimum lithium concentration 595 increased 15% and the renal clearance was decreased by approximately 20%. 596 These effects have been attributed to inhibition of renal prostaglandin 597 synthesis by the NSAID. Thus, when NSAIDs and lithium are administered 598 concurrently, subjects should be observed carefully for signs of lithium 599 toxicity. 600 Methotrexate 601 NSAIDs have been reported to competitively inhibit methotrexate 602 accumulation in rabbit kidney slices. Naproxen, naproxen sodium and other 603 nonsteroidal anti-inflammatory drugs have been reported to reduce the tubular 604 secretion of methotrexate in an animal model. This may indicate that they 605 could enhance the toxicity of methotrexate. Caution should be used when 606 NSAIDs are administered concomitantly with methotrexate. 607 Warfarin 608 The effects of warfarin and NSAIDs on GI bleeding are synergistic, such that 609 users of both drugs together have a risk of serious GI bleeding higher than 610 users of either drug alone. No significant interactions have been observed in 611 clinical studies with naproxen and coumarin-type anticoagulants. However, 612 caution is advised since interactions have been seen with other nonsteroidal 613 agents of this class. The free fraction of warfarin may increase substantially in 614 some subjects and naproxen interferes with platelet function. 615 Selective Serotonin Reuptake Inhibitors (SSRIs) 616 There is an increased risk of gastrointestinal bleeding when selective serotonin 617 reuptake inhibitors (SSRIs) are combined with NSAIDs. Caution should be 618 used when NSAIDs are administered concomitantly with SSRIs. 619 Other Information Concerning Drug Interactions 620 Naproxen is highly bound to plasma albumin; it thus has a theoretical 621 potential for interaction with other albumin-bound drugs such as coumarin­ 17 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda EC-NAPROSYN® (naproxen delayed-release tablets), NAPROSYN® (naproxen tablets), ANAPROX®/ANAPROX® DS (naproxen sodium tablets), NAPROSYN® (naproxen suspension) 622 type anticoagulants, sulphonylureas, hydantoins, other NSAIDs, and aspirin. 623 Patients simultaneously receiving naproxen and a hydantoin, sulphonamide or 624 sulphonylurea should be observed for adjustment of dose if required. 625 Naproxen and other nonsteroidal anti-inflammatory drugs can reduce the 626 antihypertensive effect of propranolol and other beta-blockers. 627 Probenecid given concurrently increases naproxen anion plasma levels and 628 extends its plasma half-life significantly. 629 Due to the gastric pH elevating effects of H2-blockers, sucralfate and intensive 630 antacid therapy, concomitant administration of EC-NAPROSYN is not 631 recommended. 632 Drug/Laboratory Test Interaction 633 Naproxen may decrease platelet aggregation and prolong bleeding time. This 634 effect should be kept in mind when bleeding times are determined. 635 The administration of naproxen may result in increased urinary values for 17­ 636 ketogenic steroids because of an interaction between the drug and/or its 637 metabolites with m-di-nitrobenzene used in this assay. Although 17-hydroxy­ 638 corticosteroid measurements (Porter-Silber test) do not appear to be 639 artifactually altered, it is suggested that therapy with naproxen be temporarily 640 discontinued 72 hours before adrenal function tests are performed if the 641 Porter-Silber test is to be used. 642 Naproxen may interfere with some urinary assays of 5-hydroxy indoleacetic 643 acid (5HIAA). 644 Carcinogenesis 645 A 2-year study was performed in rats to evaluate the carcinogenic potential of 646 naproxen at rat doses of 8, 16, and 24 mg/kg/day (50, 100, and 150 mg/m2). 647 The maximum dose used was 0.28 times the systemic exposure to humans at 648 the recommended dose. No evidence of tumorigenicity was found. 649 Pregnancy 650 Teratogenic Effects 651 Pregnancy Category C 652 Reproduction studies have been performed in rats at 20 mg/kg/day 653 (125 mg/m2/day, 0.23 times the human systemic exposure), rabbits at 20 654 mg/kg/day (220 mg/m2/day, 0.27 times the human systemic exposure), and 655 mice at 170 mg/kg/day (510 mg/m2/day, 0.28 times the human systemic 656 exposure) with no evidence of impaired fertility or harm to the fetus due to the 657 drug. However, animal reproduction studies are not always predictive of 18 This label may not be the latest approved by FDA.

There are no adequate and well-controlled studies in 659 pregnant women. NAPROSYN, EC-NAPROSYN, ANAPROX, ANAPROX 660 DS and NAPROSYN Suspension should be used in pregnancy only if the 661 potential benefit justifies the potential risk to the fetus. 662 Nonteratogenic Effects 663 There is some evidence to suggest that when inhibitors of prostaglandin 664 synthesis are used to delay preterm labor there is an increased risk of neonatal 665 complications such as necrotizing enterocolitis, patent ductus arteriosus and 666 intracranial hemorrhage. Naproxen treatment given in late pregnancy to delay 667 parturition has been associated with persistent pulmonary hypertension, renal 668 dysfunction and abnormal prostaglandin E levels in preterm infants. Because 669 of the known effects of nonsteroidal anti-inflammatory drugs on the fetal 670 cardiovascular system (closure of ductus arteriosus), use during pregnancy 671 (particularly late pregnancy) should be avoided. 672 Labor and Delivery 673 In rat studies with NSAIDs, as with other drugs known to inhibit 674 prostaglandin synthesis, an increased incidence of dystocia, delayed 675 parturition, and decreased pup survival occurred. Naproxen-containing 676 products are not recommended in labor and delivery because, through its 677 prostaglandin synthesis inhibitory effect, naproxen may adversely affect fetal 678 circulation and inhibit uterine contractions, thus increasing the risk of uterine 679 hemorrhage. The effects of NAPROSYN, EC-NAPROSYN, ANAPROX, 680 ANAPROX DS and NAPROSYN Suspension on labor and delivery in 681 pregnant women are unknown. 682 Nursing Mothers 683 The naproxen anion has been found in the milk of lactating women at a 684 concentration equivalent to approximately 1% of maximum naproxen 685 concentration in plasma. Because of the possible adverse effects of 686 prostaglandin-inhibiting drugs on neonates, use in nursing mothers should be 687 avoided. 688 Pediatric Use 689 Safety and effectiveness in pediatric patients below the age of 2 years have 690 not been established. Pediatric dosing recommendations for juvenile arthritis 691 are based on well-controlled studies (see DOSAGE AND 692 ADMINISTRATION). There are no adequate effectiveness or dose-response 693 data for other pediatric conditions, but the experience in juvenile arthritis and 694 other use experience have established that single doses of 2.5 to 5 mg/kg (as 695 naproxen suspension, see DOSAGE AND ADMINISTRATION), with total 19 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda EC-NAPROSYN® (naproxen delayed-release tablets), NAPROSYN® (naproxen tablets), ANAPROX®/ANAPROX® DS (naproxen sodium tablets), NAPROSYN® (naproxen suspension) 696 daily dose not exceeding 15 mg/kg/day, are well tolerated in pediatric patients 697 over 2 years of age. 698 Geriatric Use 699 Studies indicate that although total plasma concentration of naproxen is 700 unchanged, the unbound plasma fraction of naproxen is increased in the 701 elderly. Caution is advised when high doses are required and some adjustment 702 of dosage may be required in elderly patients. As with other drugs used in the 703 elderly, it is prudent to use the lowest effective dose. 704 Experience indicates that geriatric patients may be particularly sensitive to 705 certain adverse effects of nonsteroidal anti-inflammatory drugs. Elderly or 706 debilitated patients seem to tolerate peptic ulceration or bleeding less well 707 when these events do occur. Most spontaneous reports of fatal GI events are in 708 the geriatric population (see WARNINGS). 709 Naproxen is known to be substantially excreted by the kidney, and the risk of 710 toxic reactions to this drug may be greater in patients with impaired renal 711 function. Because elderly patients are more likely to have decreased renal 712 function, care should be taken in dose selection, and it may be useful to 713 monitor renal function. Geriatric patients may be at a greater risk for the 714 development of a form of renal toxicity precipitated by reduced prostaglandin 715 formation during administration of nonsteroidal anti-inflammatory drugs (see 716 WARNINGS: Renal Effects). 717 ADVERSE REACTIONS 718 Adverse reactions reported in controlled clinical trials in 960 patients treated 719 for rheumatoid arthritis or osteoarthritis are listed below. In general, reactions 720 in patients treated chronically were reported 2 to 10 times more frequently 721 than they were in short-term studies in the 962 patients treated for mild to 722 moderate pain or for dysmenorrhea. The most frequent complaints reported 723 related to the gastrointestinal tract. 724 A clinical study found gastrointestinal reactions to be more frequent and more 725 severe in rheumatoid arthritis patients taking daily doses of 1500 mg naproxen 726 compared to those taking 750 mg naproxen (see CLINICAL 727 PHARMACOLOGY). 728 In controlled clinical trials with about 80 pediatric patients and in well­ 729 monitored, open-label studies with about 400 pediatric patients with juvenile 730 arthritis treated with naproxen, the incidence of rash and prolonged bleeding 731 times were increased, the incidence of gastrointestinal and central nervous 732 system reactions were about the same, and the incidence of other reactions 733 were lower in pediatric patients than in adults. 20 This label may not be the latest approved by FDA.

Hypertension, acute renal failure, 811 respiratory depression, and coma may occur, but are rare. Anaphylactoid 812 reactions have been reported with therapeutic ingestion of NSAIDs, and may 813 occur following an overdose. Because naproxen sodium may be rapidly 814 absorbed, high and early blood levels should be anticipated. A few patients 815 have experienced convulsions, but it is not clear whether or not these were 816 drug-related. It is not known what dose of the drug would be life threatening. 817 The oral LD50 of the drug is 543 mg/kg in rats, 1234 mg/kg in mice, 4110 818 mg/kg in hamsters, and greater than 1000 mg/kg in dogs. 819 Treatment 820 Patients should be managed by symptomatic and supportive care following a 821 NSAID overdose. There are no specific antidotes. Hemodialysis does not 822 decrease the plasma concentration of naproxen because of the high degree of 823 its protein binding. Emesis and/or activated charcoal (60 to 100 g in adults, 1 824 to 2 g/kg in children) and/or osmotic cathartic may be indicated in patients 825 seen within 4 hours of ingestion with symptoms or following a large overdose. 826 Forced diuresis, alkalinization of urine or hemoperfusion may not be useful 827 due to high protein binding. 828 DOSAGE AND ADMINISTRATION 829 Carefully consider the potential benefits and risks of NAPROSYN, EC­ 830 NAPROSYN, ANAPROX, ANAPROX DS and NAPROSYN Suspension and 831 other treatment options before deciding to use NAPROSYN, EC­ 832 NAPROSYN, ANAPROX, ANAPROX DS and NAPROSYN Suspension. 833 Use the lowest effective dose for the shortest duration consistent with 834 individual patient treatment goals (see WARNINGS). 835 After observing the response to initial therapy with NAPROSYN, EC­ 836 NAPROSYN, ANAPROX, ANAPROX DS or NAPROSYN Suspension, the 837 dose and frequency should be adjusted to suit an individual patient’s needs. 23 This label may not be the latest approved by FDA.

This difference should be taken 840 into consideration when changing formulation. 841 Although NAPROSYN, NAPROSYN Suspension, EC-NAPROSYN, 842 ANAPROX and ANAPROX DS all circulate in the plasma as naproxen, they 843 have pharmacokinetic differences that may affect onset of action. Onset of 844 pain relief can begin within 30 minutes in patients taking naproxen sodium 845 and within 1 hour in patients taking naproxen. Because EC-NAPROSYN 846 dissolves in the small intestine rather than in the stomach, the absorption of 847 the drug is delayed compared to the other naproxen formulations (see 848 CLINICAL PHARMACOLOGY). 849 The recommended strategy for initiating therapy is to choose a formulation 850 and a starting dose likely to be effective for the patient and then adjust the 851 dosage based on observation of benefit and/or adverse events. A lower dose 852 should be considered in patients with renal or hepatic impairment or in elderly 853 patients (see WARNINGS and PRECAUTIONS). 854 Geriatric Patients 855 Studies indicate that although total plasma concentration of naproxen is 856 unchanged, the unbound plasma fraction of naproxen is increased in the 857 elderly. Caution is advised when high doses are required and some adjustment 858 of dosage may be required in elderly patients. As with other drugs used in the 859 elderly, it is prudent to use the lowest effective dose. 860 Patients With Moderate to Severe Renal Impairment 861 Naproxen-containing products are not recommended for use in patients with 862 moderate to severe and severe renal impairment (creatinine clearance <30 863 mL/min) (see WARNINGS: Renal Effects). 864 Rheumatoid Arthritis, Osteoarthritis and Ankylosing Spondylitis NAPROSYN 250 mg or 375 mg or 500 mg twice daily twice daily twice daily ANAPROX 275 mg (naproxen 250 mg with 25 mg sodium) twice daily ANAPROX DS 550 mg (naproxen 500 mg with 50 mg sodium) twice daily NAPROSYN Suspension 250 mg (10 mL/2 tsp) or 375 mg (15 mL/3 tsp) or 500 mg (20 mL/4 tsp) twice daily twice daily twice daily EC-NAPROSYN 375 mg or 500 mg twice daily twice daily 24 This label may not be the latest approved by FDA.

NAPROSYN 867 Suspension should be shaken gently before use. 868 During long-term administration, the dose of naproxen may be adjusted up or 869 down depending on the clinical response of the patient. A lower daily dose 870 may suffice for long-term administration. The morning and evening doses do 871 not have to be equal in size and the administration of the drug more frequently 872 than twice daily is not necessary. 873 In patients who tolerate lower doses well, the dose may be increased to 874 naproxen 1500 mg/day for limited periods of up to 6 months when a higher 875 level of anti-inflammatory/analgesic activity is required. When treating such 876 patients with naproxen 1500 mg/day, the physician should observe sufficient 877 increased clinical benefits to offset the potential increased risk. The morning 878 and evening doses do not have to be equal in size and administration of the 879 drug more frequently than twice daily does not generally make a difference in 880 response (see CLINICAL PHARMACOLOGY). 881 Juvenile Arthritis 882 The use of NAPROSYN Suspension is recommended for juvenile arthritis in 883 children 2 years or older because it allows for more flexible dose titration 884 based on the child’s weight. In pediatric patients, doses of 5 mg/kg/day 885 produced plasma levels of naproxen similar to those seen in adults taking 500 886 mg of naproxen (see CLINICAL PHARMACOLOGY). 887 The recommended total daily dose of naproxen is approximately 10 mg/kg 888 given in 2 divided doses (ie, 5 mg/kg given twice a day). A measuring cup 889 marked in 1/2 teaspoon and 2.5 milliliter increments is provided with the 890 NAPROSYN Suspension. The following table may be used as a guide for 891 dosing of NAPROSYN Suspension: 892 Patient’s Weight Dose Administered as 893 13 kg (29 lb) 62.5 mg bid 2.5 mL (1/2 tsp) twice daily 894 25 kg (55 lb) 125 mg bid 5.0 mL (1 tsp) twice daily 895 38 kg (84 lb) 187.5 mg bid 7.5 mL (1 1/2 tsp) twice daily 896 Management of Pain, Primary Dysmenorrhea, and Acute 897 Tendonitis and Bursitis 898 The recommended starting dose is 550 mg of naproxen sodium as 899 ANAPROX/ANAPROX DS followed by 550 mg every 12 hours or 275 mg 900 every 6 to 8 hours as required. The initial total daily dose should not exceed 901 1375 mg of naproxen sodium. Thereafter, the total daily dose should not 25 This label may not be the latest approved by FDA.

Because the sodium salt of naproxen is 903 more rapidly absorbed, ANAPROX/ANAPROX DS is recommended for the 904 management of acute painful conditions when prompt onset of pain relief is 905 desired. NAPROSYN may also be used but EC-NAPROSYN is not 906 recommended for initial treatment of acute pain because absorption of 907 naproxen is delayed compared to other naproxen-containing products (see 908 CLINICAL PHARMACOLOGY, INDICATIONS AND USAGE). 909 Acute Gout 910 The recommended starting dose is 750 mg of NAPROSYN followed by 250 911 mg every 8 hours until the attack has subsided. ANAPROX may also be used 912 at a starting dose of 825 mg followed by 275 mg every 8 hours.

CeeNU (lomustine) Capsules WARNINGS CeeNU (lomustine) should be administered under the supervision of a qualified physician experienced in the use of cancer chemotherapeutic agents. Bone marrow suppression, notably thrombocytopenia and leukopenia, which may contribute to bleeding and overwhelming infections in an already compromised patient, is the most common and severe of the toxic effects of CeeNU (see WARNINGS and ADVERSE REACTIONS). Since the major toxicity is delayed bone marrow suppression, blood counts should be monitored weekly for at least 6 weeks after a dose (see ADVERSE REACTIONS). At the recommended dosage, courses of CeeNU should not be given more frequently than every 6 weeks. The bone marrow toxicity of CeeNU is cumulative and therefore dosage adjustment must be considered on the basis of nadir blood counts from prior dose (see dosage adjustment table under DOSAGE AND ADMINISTRATION). DESCRIPTION CeeNU® (lomustine) (CCNU) is one of the nitrosoureas used in the treatment of certain neoplastic diseases. It is 1-(2-chloro-ethyl)-3-cyclohexyl-1-nitrosourea. It is a yellow powder with the empirical formula of C9H16ClN3O2 and a molecular weight of 233.71. CeeNU is soluble in 10% ethanol (0.05 mg per mL) and in absolute alcohol (70 mg per mL). CeeNU is relatively insoluble in water (<0.05 mg per mL). It is relatively un-ionized at a physiological pH. Inactive ingredients in CeeNU Capsules are magnesium stearate and mannitol. 1 Reference ID: 3220000 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda The structural formula is: structural formula CeeNU is available in 10 mg, 40 mg, and 100 mg capsules for oral administration. CLINICAL PHARMACOLOGY Although it is generally agreed that CeeNU alkylates DNA and RNA, it is not cross resistant with other alkylators. As with other nitrosoureas, it may also inhibit several key enzymatic processes by carbamoylation of amino acids in proteins. CeeNU may be given orally. Following oral administration of radioactive CeeNU at doses ranging from 30 mg/m2 to 100 mg/m2, about half of the radioactivity given was excreted in the urine in the form of degradation products within 24 hours. The serum half-life of the metabolites ranges from 16 hours to 2 days. Tissue levels are comparable to plasma levels at 15 minutes after intravenous administration. Because of the high lipid solubility and the relative lack of ionization at physiological pH, CeeNU crosses the blood-brain barrier quite effectively. Levels of radioactivity in the CSF are 50% or greater than those measured concurrently in plasma. INDICATIONS AND USAGE CeeNU has been shown to be useful as a single agent in addition to other treatment modalities, or in established combination therapy with other approved chemotherapeutic agents in the following: Brain tumors—both primary and metastatic, in patients who have already received appropriate surgical and/or radiotherapeutic procedures. Hodgkin’s disease—secondary therapy in combination with other approved drugs in patients who relapse while being treated with primary therapy, or who fail to respond to primary therapy. 2 Reference ID: 3220000 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda CONTRAINDICATIONS CeeNU should not be given to individuals who have demonstrated a previous hypersensitivity to it. WARNINGS Since the major toxicity is delayed bone marrow suppression, blood counts should be monitored weekly for at least 6 weeks after a dose (see ADVERSE REACTIONS). At the recommended dosage, courses of CeeNU should not be given more frequently than every 6 weeks. The bone marrow toxicity of CeeNU is cumulative and therefore dosage adjustment must be considered on the basis of nadir blood counts from prior dose (see dosage adjustment table under DOSAGE AND ADMINISTRATION). Pulmonary toxicity from CeeNU appears to be dose related (see ADVERSE REACTIONS). Long-term use of nitrosoureas has been reported to be possibly associated with the development of secondary malignancies. Liver and renal function tests should be monitored periodically (see ADVERSE REACTIONS). Pregnancy Category D CeeNU can cause fetal harm when administered to a pregnant woman. CeeNU is embryotoxic and teratogenic in rats and embryotoxic in rabbits at dose levels equivalent to the human dose. There are no adequate and well controlled studies in pregnant women. If this drug is used during pregnancy, or if the patient becomes pregnant while taking (receiving) this drug, the patient should be apprised of the potential hazard to the fetus. Women of childbearing potential should be advised to avoid becoming pregnant. PRECAUTIONS General In all instances where the use of CeeNU is considered for chemotherapy, the physician must evaluate the need and usefulness of the drug against the risks of toxic effects or adverse reactions. Most such adverse reactions are reversible if detected early. When such effects or reactions do occur, the drug should be reduced in dosage or discontinued and appropriate corrective measures should be taken according to the clinical judgment of the physician. Reinstitution of CeeNU therapy should be carried out with caution and with adequate 3 Reference ID: 3220000 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda consideration of the further need for the drug and alertness as to possible recurrence of toxicity. Information for Patients Provide patients with the following information and instructions: 1. In order to provide the proper dose of CeeNU, the dose may be made up of 2 or more different strengths and colors of capsules. Each strength must be dispensed separately by the pharmacist. 2. CeeNU is given as a single oral dose and will not be repeated for at least 6 weeks. Daily use of the recommended dose may lead to toxicities and fatal outcomes. 3. Patients may experience nausea and vomiting that usually last less than 24 hours. Patients may also experience loss of appetite that may last for several days. 4. Instruct patients to contact their physician if they develop any of the following reactions: fever, chills, sore throat, unusual bleeding or bruising, shortness of breath, dry cough, swelling of feet or lower legs, mental confusion, or yellowing of eyes and skin. 5. Instruct patients to wear impervious (rubber or latex) gloves when handling CeeNU Capsules. Laboratory Tests Due to delayed bone marrow suppression, blood counts should be monitored weekly for at least 6 weeks after a dose. Baseline pulmonary function studies should be conducted along with frequent pulmonary function tests during treatment. Patients with a baseline below 70% of the predicted Forced Vital Capacity (FVC) or Carbon Monoxide Diffusing Capacity (DLCO) are particularly at risk. Since CeeNU may cause liver dysfunction, it is recommended that liver function tests be monitored periodically. Renal function tests should also be monitored periodically. 4 Reference ID: 3220000 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda Carcinogenesis, Mutagenesis, Impairment of Fertility CeeNU is carcinogenic in rats and mice, producing a marked increase in tumor incidence in doses approximating those employed clinically. Nitrosourea therapy does have carcinogenic potential in humans (see ADVERSE REACTIONS). CeeNU also affects fertility in male rats at doses somewhat higher than the human dose. Pregnancy Pregnancy Category D See WARNINGS. Nursing Mothers It is not known whether this drug is excreted in human milk. Because many drugs are excreted in human milk and because of the potential for serious adverse reactions in nursing infants from CeeNU, a decision should be made whether to discontinue nursing or to discontinue the drug, taking into account the importance of the drug to the mother. Pediatric Use See ADVERSE REACTIONS: Pulmonary Toxicity and DOSAGE AND ADMINISTRATION. Geriatric Use No data from clinical studies of CeeNU are available for patients 65 years of age and over to determine whether they respond differently than younger patients. Other reported clinical experience has not identified differences in responses between elderly and younger patients. In general, dose selection for an elderly patient should be cautious, reflecting the greater frequency of decreased hepatic, renal, or cardiac function and of concomitant disease or other drug therapy. Lomustine and its metabolites are known to be substantially excreted by the kidney, and the risk of toxic reactions to this drug may be greater in patients with impaired renal function. Because elderly patients are more likely to have decreased renal function, care should be taken in dose selection, and renal function should be monitored. 5 Reference ID: 3220000 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda ADVERSE REACTIONS Hematologic Toxicity The most frequent and most serious toxicity of CeeNU is delayed myelosuppression. It usually occurs 4 to 6 weeks after drug administration and is dose related. Thrombocytopenia occurs at about 4 weeks postadministration and persists for 1 to 2 weeks. Leukopenia occurs at 5 to 6 weeks after a dose of CeeNU and persists for 1 to 2 weeks. Approximately 65% of patients receiving 130 mg/m2 develop white blood counts below 5000 wbc/mm3. Thirty-six percent developed white blood counts below 3000 wbc/mm3. Thrombocytopenia is generally more severe than leukopenia. However, both may be dose-limiting toxicities. CeeNU may produce cumulative myelosuppression, manifested by more depressed indices or longer duration of suppression after repeated doses. The occurrence of acute leukemia and bone marrow dysplasias have been reported in patients following long-term nitrosourea therapy. Anemia also occurs, but is less frequent and less severe than thrombocytopenia or leukopenia. Pulmonary Toxicity Pulmonary toxicity characterized by pulmonary infiltrates and/or fibrosis has been reported rarely with CeeNU. Onset of toxicity has occurred after an interval of 6 months or longer from the start of therapy with cumulative doses of CeeNU usually greater than 1100 mg/m2. There is 1 report of pulmonary toxicity at a cumulative dose of only 600 mg. Delayed onset pulmonary fibrosis occurring up to 17 years after treatment has been reported in patients who received related nitrosoureas in childhood and early adolescence (1–16 years) combined with cranial radiotherapy for intracranial tumors. There appeared to be some late reduction of pulmonary function of all long-term survivors. This form of lung fibrosis may be slowly progressive and has resulted in death in some cases. In this long-term study of carmustine, all those initially treated at less than 5 years of age died of delayed pulmonary fibrosis. Gastrointestinal Toxicity Nausea and vomiting may occur 3 to 6 hours after an oral dose and usually last less than 24 hours. Prior administration of antiemetics is effective in diminishing and sometimes preventing this side effect. Nausea and vomiting can also be reduced if CeeNU is administered to fasting patients. 6 Reference ID: 3220000 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda Hepatotoxicity A reversible type of hepatic toxicity, manifested by increased transaminase, alkaline phosphatase, and bilirubin levels, has been reported in a small percentage of patients receiving CeeNU. Nephrotoxicity Renal abnormalities consisting of progressive azotemia, decrease in kidney size, and renal failure have been reported in patients who received large cumulative doses after prolonged therapy with CeeNU. Kidney damage has also been reported occasionally in patients receiving lower total doses. Other Toxicities Stomatitis, alopecia, optic atrophy, and visual disturbances, such as blindness, have been reported infrequently. Neurological reactions, such as disorientation, lethargy, ataxia, and dysarthria have been noted in some patients receiving CeeNU. However, the relationship to medication in these patients is unclear. OVERDOSAGE Accidental overdose with lomustine has been reported, including fatal cases. Accidental overdose has been associated with bone marrow suppression, abdominal pain, diarrhea, vomiting, anorexia, lethargy, dizziness, abnormal hepatic function, cough, and shortness of breath. No proven antidotes have been established for CeeNU overdosage. In case of overdose, appropriate supportive measures should be taken. DOSAGE AND ADMINISTRATION The recommended dose of CeeNU in adult and pediatric patients as a single agent in previously untreated patients is 130 mg/m2 as a single oral dose every 6 weeks (see PRECAUTIONS: Information for Patients and HOW SUPPLIED: Directions to the Pharmacist). In individuals with compromised bone marrow function, the dose should be reduced to 100 mg/m2 every 6 weeks. When CeeNU is used in combination with other myelosuppressive drugs, the doses should be adjusted accordingly. All doses of CeeNU must be rounded to the nearest 10 mg by the prescriber (see HOW SUPPLIED). 7 Reference ID: 3220000 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda Doses subsequent to the initial dose should be adjusted according to the hematologic response of the patient to the preceding dose. The following schedule is suggested as a guide to dosage adjustment: Nadir After Prior Dose Percentage of Prior Dose to be Given Leukocytes (/mm3) Platelets (/mm3) 4000 3000–3999 2000–2999 <2000 100,000 75,000–99,999 25,000–74,999 <25,000 100% 100% 70% 50% A repeat course of CeeNU should not be given until circulating blood elements have returned to acceptable levels (platelets above 100,000/mm3; leukocytes above 4000/mm3), and this is usually in 6 weeks. Adequate number of neutrophils should be present on a peripheral blood smear. Blood counts should be monitored weekly and repeat courses should not be given before 6 weeks because the hematologic toxicity is delayed and cumulative. HOW SUPPLIED CeeNU® (lomustine) Capsules are available in individual bottles of 20 capsules each. NDC 0015-3032-20 100 mg capsules (Green/Green) NDC 0015-3031-20 40 mg capsules (White/Green) NDC 0015-3030-20 10 mg capsules (White/White) Stability CeeNU Capsules are stable for the lot life indicated on package labeling when stored in well- closed containers at 25°C (77°F); excursions permitted to 15°C–30°C (59°F–86°F) [see USP Controlled Room Temperature]. Avoid excessive heat (over 40°C, 104°F). Directions to the Pharmacist Confirm the total dose prescribed by the physician can be obtained by determining the appropriate combination of capsule strengths. Only the appropriate number of CeeNU capsules required for the administration of a single dose should be dispensed. In order to provide the proper dose of CeeNU, patients should be aware that the prescribed dose may be made up of 2 or more different strengths and colors of capsules and that each strength must be dispensed separately. Inform patients that CeeNU is taken as a single oral dose and will not be repeated for at least 6 weeks. Daily use of the recommended dose may lead to toxicities and fatal outcomes. Reference ID: 3220000 8 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda Caution should be exercised when handling CeeNU Capsules. Procedures for proper handling and disposal of anticancer drugs should be utilized. Several guidelines on this subject have been published.1-4 To minimize the risk of dermal exposure, always wear impervious gloves when handling bottles containing CeeNU Capsules. CeeNU Capsules should not be broken. Personnel should avoid exposure to broken capsules. If contact occurs, wash immediately and thoroughly.

Myelosuppression is delayed, dose-related, and cumulative; occurring 4 to 6 weeks after drug administration and persisting for 1 to 2 weeks. Thrombocytopenia is generally more severe than leukopenia. Cumulative myelosuppression from Gleostine is manifested by greater severity and longer duration of cytopenias. Monitor blood counts for at least 6 weeks after each dose. Do not give Gleostine more frequently than every 6 weeks [see Warnings and Precautions (5.1), Dosage and Administration (2.2, 2.3)]. RISK OF OVERDOSAGE PRESCRIBE, DISPENSE, AND ADMINISTER ONLY ENOUGH CAPSULES FOR ONE DOSE. Fatal toxicity occurs with overdosage of Gleostine. Both physician and pharmacist should emphasize to the patient that only one dose of Gleostine is taken every 6 weeks [see Dosage and Administration (2.1), Warnings and Precautions (5.2), Overdosage (10)]. 1 INDICATIONS AND USAGE 1.1 Brain Tumors Gleostine is indicated for the treatment of patients with primary and metastatic brain tumors following appropriate surgical and/or radiotherapeutic procedures. 1.2 Hodgkin’s Lymphoma Gleostine is indicated as a component of combination chemotherapy for the treatment of patients with Hodgkin’s lymphoma whose disease has progressed following initial chemotherapy. 2 DOSAGE AND ADMINISTRATION 2.1 Important Prescribing and Dispensing Information PRESCRIBE ONLY ONE DOSE FOR EACH TREATMENT CYCLE. DO NOT DISPENSE ENTIRE CONTAINER. Dispense only a sufficient number of capsules for one dose. Confirm the total dose prescribed by the physician and the appropriate combination of capsule strengths. Dispense only the appropriate number of Gleostine capsules required for the administration of a single dose. The prescribed dose may consist of two or more different strengths and colors of capsules. Instruct patients that Gleostine is taken as a single oral dose and will not be repeated for at least 6 weeks. Taking more than the recommended dose causes toxicities, including fatal outcomes [see Warnings and Precautions (5.2) and Overdosage (10)]. Gleostine is a cytotoxic drug. Follow applicable special handling and disposal procedures. 1 To minimize the risk of dermal exposure, always wear impervious gloves when handling bottles containing Gleostine capsules. Do not break Gleostine capsules; avoid exposure to broken capsules. If dermal contact occurs, wash areas of skin contact immediately and thoroughly.

For current labeling information, please visit https://www.fda.gov/drugsatfda 2.2 Recommended Dose The recommended dose of Gleostine in adult and pediatric patients is 130 mg/m2 taken as a single oral dose every 6 weeks. Round doses to the nearest 5 mg. Give as a single oral dose and do not repeat for at least 6 weeks. Reduce dose to 100 mg/m2 every 6 weeks in patients with compromised bone marrow function. Also reduce dose accordingly when using with other myelosuppressive drugs. 2.3 Dose Modifications Perform weekly complete blood counts and withhold each subsequent dose for more than 6 weeks if needed until platelet counts recover to 100,000/mm3 or greater and leukocytes recover to 4000/mm3or greater [see Warnings and Precautions (5.1)]. Modify each dose of Gleostine according to the hematologic response of the preceding dose as described in Table 1: Table 1. Dose Modifications for Gleostine Nadir After Prior Dose Dose Adjustment Leukocytes (/mm3) Platelets (/mm3) ≥ 4000 ≥ 100,000 None 3000 – 3999 75,000 – 99,999 None 2000 – 2999 25,000 – 74,999 Reduce dose by 70% < 2000 < 25,000 Reduce dose by 50% 3 DOSAGE FORMS AND STRENGTHS Gleostine capsules are available in four strengths, distinguishable by the color of the capsules:  100 mg capsules (green/green)  40 mg capsules (white/green)  10 mg capsules (white/white)  5 mg capsules (yellow/yellow) 4 CONTRAINDICATIONS None. 5 WARNINGS AND PRECAUTIONS 5.1 Delayed Myelosuppression Gleostine causes myelosuppression that can result in fatal infections and bleeding. Myelosuppression from Gleostine is delayed, dose-related, and cumulative. It usually occurs 4 to 6 weeks after drug administration and persists for 1 to 2 weeks. Thrombocytopenia is generally more severe than leukopenia. Cumulative myelosuppression from Gleostine is manifested by greater severity and longer duration of cytopenias. Page 3 of 10 Reference ID: 3869801 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda Monitor blood counts for at least 6 weeks after each dose. Do not give Gleostine more frequently than every 6 weeks. Adjust dose based on nadir blood counts from prior dose [see Dosage and Administration (2.3)]. 5.2 Risk of Overdosage Fatal toxicity occurs with overdosage of Gleostine. Dispensing or administering more than one dose can lead to fatal toxicity. Prescribe only one dose at a time. Dispense only enough capsules for one dose. Both physician and pharmacist should emphasize to the patient that only one dose of Gleostine is taken every 6 weeks [see Dosage and Administration (2.1) and Overdosage (10)]. 5.3 Pulmonary Toxicity Pulmonary toxicity characterized by pulmonary infiltrates and/or fibrosis occurs with Gleostine. Patients with a baseline below 70% of the predicted Forced Vital Capacity (FVC) or Carbon Monoxide Diffusing Capacity (DLCO) are at increased risk. The onset of pulmonary toxicity occurs after an interval of 6 months or longer from the start of therapy, with cumulative doses of Gleostine usually greater than 1100 mg/m2. Obtain baseline pulmonary function tests prior to initiating treatment and repeat frequently during treatment. Permanently discontinue Gleostine in patients diagnosed with pulmonary fibrosis. 5.4 Secondary Malignancies Secondary malignancies, including acute leukemia and myelodysplasia, occur with long term use. 5.5 Hepatotoxicity Hepatic toxicity, manifested by increased levels of transaminases, alkaline phosphatase, and bilirubin occurs with Gleostine. Monitor liver function. 5.6 Nephrotoxicity Progressive renal failure with a decrease in kidney size occurs with Gleostine. Monitor renal function. 5.7 Embryo-Fetal Toxicity Based on animal data and its mechanism of action, Gleostine can cause fetal harm when administered to a pregnant woman. Embryo-fetal toxicity and teratogenicity occurred in rats and rabbits receiving lomustine daily during organogenesis at doses approximately two to four times the total human dose of 130 mg/m2 over 6 weeks (0.18 to 0.27 times the single human dose of 130 mg/m2) based on body surface area (BSA). Advise pregnant women of the potential risk to a fetus. Advise females of reproductive potential to use effective contraception during treatment with Gleostine and for 2 weeks after the final dose. Advise males with female partners of reproductive potential to use effective contraception during treatment with Gleostine and for 3.5 months after the final dose [see Use in Specific Populations (8.1, 8.3)].

For current labeling information, please visit https://www.fda.gov/drugsatfda   6 ADVERSE REACTIONS The following serious adverse reactions are discussed in greater detail in other sections of the labeling:  Delayed myelosuppression [see Warnings and Precautions (5.1)]  Risks of overdosage [see Warnings and Precautions (5.2)]  Pulmonary toxicity [see Warnings and Precautions (5.3)]  Secondary malignancies [see Warnings and Precautions (5.4)]  Hepatotoxicity [see Warnings and Precautions (5.5)]  Nephrotoxicity [see Warnings and Precautions (5.6)] The following adverse reactions associated with the use of Gleostine were identified in clinical trials or postmarketing reports. Because these reactions were reported from a population of uncertain size, it is not possible to estimate their frequency, reliability, or establishment a causal relationship to drug exposure. Gastrointestinal disorders: nausea, vomiting, and stomatitis Ocular disorders: optic atrophy, visual disturbances, and blindness Neurologic disorders: disorientation, lethargy, ataxia, and dysarthria Other: alopecia 8 USE IN SPECIFIC POPULATIONS 8.1 Pregnancy Risk Summary Based on animal data and its mechanism of action, Gleostine can cause fetal harm when administered to a pregnant woman [see Clinical Pharmacology (12.1)]. There are no available data on Gleostine exposure in pregnant women. Lomustine was teratogenic in rats and embryotoxic in rabbits at total dose levels approximately two to four times the total human dose of 130 mg/m2 over 6 weeks (0.18 to 0.27 times the single human dose of 130 mg/m2) based on BSA [see Data]. Advise pregnant women of the potential risk to a fetus. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2-4% and 15-20%, respectively. Data Animal Data Lomustine was administered by intraperitoneal injection daily to pregnant rats during the period of organogenesis at dose levels of 0, 2, 4, 6, and 8 mg/kg. Resorption rates and post-implantation loss occurred at doses greater than or equal to 4 mg/kg (approximately 0.18 times the clinical dose of 130 mg/m2 based on BSA or approximately twice the total clinical dose of lomustine over 6 weeks). Malformations (omphalocele, ectepia cordis, scoliosis, syndactyly, hydrocephalus, microphthalmia, anophthalmia, anomalies of aortic arch, dextrocardia, malpositioning of the ovaries and testes, sternoschisis, and shortened/misshapen bone of the fore or hind limbs) and decreased fetal body weight occurred at all dose levels. In pregnant rabbits treated with Page 5 of 10 Reference ID: 3869801 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda lomustine at 3 mg/kg (approximately 0.27 times the 130 mg/m2 clinical dose based on BSA or approximately four times the total clinical dose of lomustine over 6 weeks) during organogenesis, there were increases in abortions and decreases in surviving pup weight that persisted postnatally. 8.2 Lactation Risk Summary There is no information on the presence of lomustine or its metabolites in human milk, its effects on the breastfed infant, or its effects on milk production. Because of the potential for serious adverse reactions in breastfed infants from Gleostine, advise women not to breastfeed during treatment with Gleostine and for 2 weeks after the final dose. 8.3 Females and Males of Reproductive Potential Contraception Females Based on animal data and its mechanism of action, Gleostine can cause fetal harm [see Use in Specific Populations (8.1)]. Advise females of reproductive potential to use effective contraception during treatment and for 2 weeks after the final dose. Males Based on Gleostine’s mechanism of action, advise males with female partners of reproductive potential to use effective contraception during treatment with Gleostine and for 3.5 months after the final dose [see Clinical Pharmacology (12.1)]. Infertility Based on animal findings and its mechanism of action, Gleostine may result in reduced fertility in males and females of reproductive potential [see Nonclinical Toxicology (13.1)]. 8.4 Pediatric Use Pediatric use, including dose, is not based on adequate and well-controlled clinical studies. 8.5 Geriatric Use No data in the clinical studies of Gleostine are available for patients 65 years of age and over to determine whether they respond differently than younger patients. Other reported clinical experience has not identified differences in responses between elderly and younger patients. In general, dose selection for an elderly patient should be cautious, reflecting the greater frequency of decreased hepatic, renal, or cardiac function and of concomitant disease or other drug therapy. Lomustine and its metabolites are known to be substantially excreted by the kidney, and the risk of toxic reactions to this drug may be greater in patients with impaired renal function. Because elderly patients are more likely to have decreased renal function, care should be taken in dose selection, and renal function should be monitored.

For current labeling information, please visit https://www.fda.gov/drugsatfda   10 OVERDOSAGE Overdosage with Gleostine has occurred, including fatal cases [see Dosage and Administration (2.1), Warnings and Precautions (5.2)]. Overdosage causes severe myelosuppression, as well as abdominal pain, diarrhea, vomiting, anorexia, lethargy, dizziness, abnormal hepatic function, cough, and shortness of breath. No antidotes exist for Gleostine overdosage. 11 DESCRIPTION Gleostine (lomustine) is an alkylating drug for oral administration. The chemical name for lomustine is 1-(2­ chloro-ethyl)-3-cyclohexyl-1-nitrosourea and the molecular formula is C9H16ClN3O2. The molecular weight is 233.71. Lomustine is a yellow powder, which is soluble in 10% ethanol (0.05 mg per mL) and in absolute alcohol (70 mg per mL). Lomustine is insoluble in water (<0.05 mg per mL). The chemical structure is: Gleostine is supplied as 5 mg, 10 mg, 40 mg, and 100 mg capsules and contains the following inactive ingredients: magnesium stearate NF and mannitol USP. The capsule shells are composed of gelatin and coloring pigments, depending on the strength: titanium dioxide, and/or yellow iron oxide, and/or Indigotine – FD&C Blue2. 12 CLINICAL PHARMACOLOGY 12.1 Mechanism of Action Lomustine alkylates DNA and RNA. As with other nitrosoureas, it may also inhibit several key enzymatic processes by carbamoylation of amino acids in proteins. 12.2 Pharmacodynamic The pharmacodynamics of lomustine are unknown. 12.3 Pharmacokinetics Distribution Lomustine crosses the blood-brain barrier. Elimination The serum half-life of lomustine metabolites ranges from 16 hours to 48 hours. Metabolism Metabolic pathways involved in the elimination of lomustine have not been characterized.

For current labeling information, please visit https://www.fda.gov/drugsatfda Excretion Following oral administration of radioactive lomustine at doses ranging from 30 mg/m2 to 100 mg/m2, approximately half of the radioactivity administered was excreted in the urine in the form of degradation products within 24 hours. Specific Populations The impact of patient specific (e.g., age, sex, and race) or disease (e.g., renal or hepatic impairment) characteristics on the pharmacokinetics of lomustine is unknown. 13 NONCLINICAL TOXICOLOGY 13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility Lomustine is carcinogenic in rats and mice, producing a marked increase in tumor incidence in doses lower than those employed clinically. In female rats, daily intraperitoneal treatment with lomustine for 2 weeks prior to mating with untreated males resulted in dose dependent decreases in number of corpora lutea and resorption rates with no live births at a dose of 3 mg/kg (approximately 0.14 times the recommended clinical dose of 130 mg/m2 based on body surface area (BSA), or approximately twice the total clinical dose of lomustine over 6 weeks) and decreased pup survival during the first 4 postnatal days at doses greater than or equal to 1.5 mg/kg (a daily dose of approximately 0.06 times the recommended clinical dose of 130 mg/m2 based on BSA or approximately equal to the total clinical dose of lomustine over 6 weeks). Gleostine may also result in decreased male fertility. Intraperitoneal injection of lomustine resulted in decreased fertility in male rats mated to untreated females based on decreased implantations and decreased fetal body weight at weekly doses greater than or equal to 5 mg/kg (approximately 0.23 times the single clinical dose of 130 mg/m2 based on BSA, or approximately equal to the total clinical dose of lomustine over 6 weeks), and increased resorptions at doses greater than or equal to 2.5 mg/kg/week. 15 REFERENCES OSHA. http://www.osha.gov/SLTC/hazardousdrugs/index.html. 16 HOW SUPPLIED/STORAGE AND HANDLING 16.1 How Supplied Gleostine is available in four strengths, distinguishable by the color of the capsules, in individual bottles of 5 capsules each: Strength Capsule Description NDC Code 100 mg Moss green cap and body, imprinted in black ink, with "CPL" over "3032" on the cap and "100 mg" on the body of the capsule. 58181-3042-5 Page 8 of 10 Reference ID: 3869801 This label may not be the latest approved by FDA.

1 SEPTRA ® Tablets SEPTRA ® DS (Double Strength) Tablets SEPTRA ® Suspension SEPTRA ® Grape Suspension (trimethoprim and sulfamethoxazole) DESCRIPTION: SEPTRA (trimethoprim and sulfamethoxazole) is a synthetic antibacterial combination product. Each SEPTRA Tablet contains 80 mg trimethoprim and 400 mg sulfamethoxazole and the inactive ingredients docusate sodium (0.4 mg per tablet), FD&C Red No. 40, magnesium stearate, povidone, and sodium starch glycolate. Each SEPTRA DS (double strength) Tablet contains 160 mg trimethoprim and 800 mg sulfamethoxazole and the inactive ingredients docusate sodium (0.8 mg per tablet), FD&C Red No. 40, magnesium stearate, povidone, and sodium starch glycolate. Each teaspoonful (5 mL) of SEPTRA Suspension contains 40 mg trimethoprim and 200 mg sulfamethoxazole and the inactive ingredients alcohol 0.26%, methylparaben 0.1% and sodium benzoate 0.1% (added as preservatives), carboxymethylcellulose sodium, citric acid, FD&C Red No. 40 and Yellow No. 6, flavor, glycerin, microcrystalline cellulose, polysorbate 80, saccharin sodium, and sorbitol. Each teaspoonful (5 mL) of SEPTRA Grape Suspension contains 40 mg trimethoprim and 200 mg sulfamethoxazole and the inactive ingredients alcohol 0.26%, methylparaben 0.1%, and sodium benzoate 0.1% (added as preservatives), carboxymethylcellulose sodium, citric acid, FD&C Red No. 40 and Blue No. 1, flavor, glycerin, microcrystalline cellulose, polysorbate 80, saccharin sodium, This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda 2 and sorbitol. Both tablet and suspension forms are for oral administration. Trimethoprim is 5-[(3,4,5-trimethoxyphenyl)methyl]-2,4- pyrimidinediamine. It is a white to light yellow, odorless, bitter compound with a molecular weight of 290.32, and the molecular formula C14H18N4O3. The structural formula is: Sulfamethoxazole is 4-amino-N-(5-methyl-3- isoxazolyl)benzenesulfonamide. It is an almost white, odorless, tasteless compound with a molecular weight of 253.28, and the molecular formula C10H11N3O3S. The structural formula is: CLINICAL PHARMACOLOGY: SEPTRA is rapidly absorbed following oral administration. Both sulfamethoxazole and trimethoprim exist in the blood as unbound, protein-bound, and metabolized forms; sulfamethoxazole also exists as the conjugated form. The metabolism of sulfamethoxazole occurs predominately by N4- acetylation, although the glucuronide conjugate has been identified. The principal metabolites of trimethoprim are the 1- and 3-oxides and the 3’- and 4’-hydroxy derivatives. The free forms of sulfamethoxazole and trimethoprim are considered to be the therapeutically active forms. Approximately 44% of trimethoprim and 70% of sulfamethoxazole are bound to plasma proteins. The presence of 10 mg percent sulfamethoxazole in plasma decreases the protein binding of trimethoprim by an This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda 3 insignificant degree; trimethoprim does not influence the protein binding of sulfamethoxazole. Peak blood levels for the individual components occur 1 to 4 hours after oral administration. The mean serum half-lives of sulfamethoxazole and trimethoprim are 10 and 8 to 10 hours, respectively. However, patients with severely impaired renal function exhibit an increase in the half-lives of both components, requiring dosage regimen adjustment (see DOSAGE AND ADMINISTRATION). Detectable amounts of trimethoprim and sulfamethoxazole are present in the blood 24 hours after drug administration. During administration of 160 mg trimethoprim and 800 mg sulfamethoxazole b.i.d., the mean steady-state plasma concentration of trimethoprim was 1.72 mcg/mL. The steady-state minimal plasma levels of free and total sulfamethoxazole were 57.4 mcg/mL and 68.0 mcg/mL, respectively. These steady-state levels were achieved after 3 days of drug administration. 1 Excretion of sulfamethoxazole and trimethoprim is primarily by the kidneys through both glomerular filtration and tubular secretion. Urine concentrations of both sulfamethoxazole and trimethoprim are considerably higher than are the concentrations in the blood. The average percentage of the dose recovered in urine from 0 to 72 hours after a single oral dose is 84.5% for total sulfonamide and 66.8% for free trimethoprim. Thirty percent of the total sulfonamide is excreted as free sulfamethoxazole, with the remaining as N4- acetylated metabolite. 2 When administered together as SEPTRA, neither sulfamethoxazole nor trimethoprim affects the urinary excretion pattern of the other. Both trimethoprim and sulfamethoxazole distribute to sputum, vaginal fluid, and middle ear fluid; trimethoprim also distributes to bronchial secretions, and both pass the placental barrier and are excreted in human milk. Microbiology: Sulfamethoxazole inhibits bacterial synthesis of dihydrofolic acid by competing with para-aminobenzoic acid This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda 4 (PABA). Trimethoprim blocks the production of tetrahydrofolic acid from dihydrofolic acid by binding to and reversibly inhibiting the required enzyme, dihydrofolate reductase. Thus, SEPTRA blocks two consecutive steps in the biosynthesis of nucleic acids and proteins essential to many bacteria. In vitro studies have shown that bacterial resistance develops more slowly with SEPTRA than with either trimethoprim or sulfamethoxazole alone. In vitro serial dilution tests have shown that the spectrum of antibacterial activity of SEPTRA includes the common urinary tract pathogens with the exception of Pseudomonas aeruginosa. The following organisms are usually susceptible: Escherichia coli, Klebsiella species, Enterobacter species, Morganella morganii, Proteus mirabilis, and indole-positive Proteus species including Proteus vulgaris. The usual spectrum of antimicrobial activity of SEPTRA includes bacterial pathogens isolated from middle ear exudate and from bronchial secretions (Haemophilus influenzae, including ampicillin-resistant strains, and Streptococcus pneumoniae), and enterotoxigenic strains of Escherichia coli (ETEC) causing bacterial gastroenteritis. Shigella flexneri and Shigella sonnei are also usually susceptible.

Antimicrobial Agents and Chemotherapy. 1974;5:439-443. Susceptibility Testing: The recommended quantitative disc susceptibility method may be used for estimating the susceptibility of bacteria to SEPTRA. 3,4 With this procedure, a report from the laboratory of ‘‘Susceptible to trimethoprim and sulfamethoxazole’’ indicates that the infection is likely to respond to therapy with SEPTRA. If the infection is confined to the urine, a report of ‘‘Intermediate susceptibility to trimethoprim and sulfamethoxazole’’ also indicates that the infection is likely to respond. A report of ‘‘Resistant to trimethoprim and sulfamethoxazole’’ indicates that the infection is unlikely to respond to therapy with SEPTRA. Geriatric Pharmacokinetics: The pharmacokinetics of sulfamethoxazole 800 mg and trimethoprim 160 mg were studied in 6 geriatric subjects (mean age: 78.6 years) and 6 young healthy subjects (mean age: 29.3 years) using a non-US approved formulation. Pharmacokinetic values for sulfamethoxazole in geriatric subjects were similar to those observed in young adult subjects. The mean renal clearance of trimethoprim was significantly lower in geriatric subjects compared with young adult subjects (19 mL/h/kg vs. 55 mL/h/kg). However, after normalizing by body weight, the apparent total This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda 7 body clearance of trimethoprim was an average 19% lower in geriatric subjects compared with young adult subjects. 3 INDICATIONS AND USAGE: Urinary Tract Infections: For the treatment of urinary tract infections due to susceptible strains of the following organisms: Escherichia coli, Klebsiella species, Enterobacter species, Morganella morganii, Proteus mirabilis, and Proteus vulgaris. It is recommended that initial episodes of uncomplicated urinary tract infections be treated with a single effective antibacterial agent rather than the combination. Acute Otitis Media: For the treatment of acute otitis media in pediatric patients due to susceptible strains of Streptococcus pneumoniae or Haemophilus influenzae when, in the judgment of the physician, SEPTRA offers some advantage over the use of other antimicrobial agents. To date, there is limited data on the safety of repeated use of SEPTRA in pediatric patients under two years of age. SEPTRA is not indicated for prophylactic or prolonged administration in otitis media at any age. Acute Exacerbations of Chronic Bronchitis in Adults: For the treatment of acute exacerbations of chronic bronchitis due to susceptible strains of Streptococcus pneumoniae or Haemophilus influenzae when, in the judgment of the physician, SEPTRA offers some advantage over the use of a single antimicrobial agent. Travelers’ Diarrhea in Adults: For the treatment of travelers’ diarrhea due to susceptible strains of enterotoxigenic E. coli. Shigellosis: For the treatment of enteritis caused by susceptible strains of Shigella flexneri and Shigella sonnei when antibacterial therapy is indicated. This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda 8 Pneumocystis Carinii Pneumonia: For the treatment of documented Pneumocystis carinii pneumonia. For prophylaxis against Pneumocystis carinii pneumonia in individuals who are immunosuppressed and considered to be at an increased risk of developing Pneumocystis carinii pneumonia. CONTRAINDICATIONS: SEPTRA is contraindicated in patients with a known hypersensitivity to trimethoprim or sulfonamides and in patients with documented megaloblastic anemia due to folate deficiency. SEPTRA is also contraindicated in pregnant patients at term and in nursing mothers, because sulfonamides pass the placenta and are excreted in the milk and may cause kernicterus. SEPTRA is contraindicated in pediatric patients less than 2 months of age. WARNINGS: FATALITIES ASSOCIATED WITH THE ADMINISTRATION OF SULFONAMIDES, ALTHOUGH RARE, HAVE OCCURRED DUE TO SEVERE REACTIONS, INCLUDING STEVENS-JOHNSON SYNDROME, TOXIC EPIDERMAL NECROLYSIS, FULMINANT HEPATIC NECROSIS, AGRANULOCYTOSIS, APLASTIC ANEMIA, AND OTHER BLOOD DYSCRASIAS. SULFONAMIDES, INCLUDING SULFONAMIDE-CONTAINING PRODUCTS SUCH AS TRIMETHOPRIM/SULFAMETHOXAZOLE, SHOULD BE DISCONTINUED AT THE FIRST APPEARANCE OF SKIN RASH OR ANY SIGN OF ADVERSE REACTION. In rare instances, a skin rash may be followed by a more severe reaction, such as Stevens-Johnson syndrome, toxic epidermal necrolysis, hepatic necrosis, and serious blood disorder (see PRECAUTIONS). Clinical signs, such as rash, sore throat, fever, arthralgia, pallor, purpura, or jaundice may be early indications of serious reactions. Cough, shortness of breath, and pulmonary infiltrates are hypersensitivity reactions of the respiratory tract that have been reported in association with sulfonamide treatment. The sulfonamides should not be used for the treatment of group A beta-hemolytic streptococcal infections. In an established This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda 9 infection, they will not eradicate the streptococcus and, therefore, will not prevent sequelae such as rheumatic fever. Pseudomembranous colitis has been reported with nearly all antibacterial agents, including trimethoprim/sulfamethoxazole, and may range in severity from mild to life-threatening. Therefore, it is important to consider this diagnosis in patients who present with diarrhea subsequent to the administration of antibacterial agents. Treatment with antibacterial agents alters the normal flora of the colon and may permit overgrowth of clostridia. Studies indicate that a toxin produced by Clostridium difficile is one primary cause of ‘‘antibiotic-associated colitis.” After the diagnosis of pseudo-membranous colitis has been established, therapeutic measures should be initiated. Mild cases of pseudomembranous colitis usually respond to drug discontinuation alone. In moderate to severe cases, consideration should be given to management with fluids andelectrolytes, protein supplementation, and treatment with an antibacterial drug effective against C. difficile. PRECAUTIONS: General: SEPTRA should be given with caution to patients with impaired renal or hepatic function, to those with possible folate deficiency (e.g., the elderly, chronic alcoholics, patients receiving anticonvulsant therapy, patients with malabsorption syndrome, and patients in malnutrition states), and to those with severe allergy or bronchial asthma. In glucose-6-phosphate dehydrogenase- deficient individuals, hemolysis may occur. This reaction is frequently dose-related (see CLINICAL PHARMACOLOGY and DOSAGE AND ADMINISTRATION). Use in the Elderly: There may be an increased risk of severe adverse reactions in elderly patients, particularly when complicating conditions exist, e.g., impaired kidney and/or liver function, or concomitant use of other drugs. Severe skin reactions, or generalized bone marrow suppression (see WARNINGS and ADVERSE REACTIONS), or a specific decrease in This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda 10 platelets (with or without purpura) are the most frequently reported severe adverse reactions in elderly patients. In those concurrently receiving certain diuretics, primarily thiazides, an increased incidence of thrombocytopenia with purpura has been reported. Appropriate dosage adjustments should be made for patients with impaired kidney function (see DOSAGE AND ADMINISTRATION). Use in the Treatment of and Prophylaxis for Pneumocystis carinii Pneumonia in Patients with Acquired Immunodeficiency Syndrome (AIDS): The incidence of side effects, particularly rash, fever, leukopenia, and elevated aminotransferase (transaminase) values in AIDS patients who are being treated with SEPTRA for Pneumocystis carinii pneumonia has been reported to be greatly increased compared with the incidence normally associated with the use of SEPTRA in non-AIDS patients. The incidence of hyperkalemia and hyponatremia appears to be increased in AIDS patients receiving SEPTRA. Adverse effects are generally less severe in patients receiving SEPTRA for prophylaxis. A history of mild intolerance to SEPTRA in AIDS patients does not appear to predict intolerance of subsequent secondary prophylaxis. However, if a patient develops skin rash or any sign of adverse reaction, therapy with SEPTRA should be re-evaluated (see WARNINGS). The concomitant use of leucovorin with trimethoprim- sulfamethoxazole for the acute treatment of Pneumocystis carinii pneumonia in patients with HIV infection was associated with increased rates of treatment failure and morbidity in a placebo-controlled study. Information for Patients: Patients should be instructed to maintain an adequate fluid intake in order to prevent crystalluria and stone formation. Laboratory Tests: Complete blood counts should be done frequently in patients receiving SEPTRA; if a significant reduction in the count of any formed blood element is noted, This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda 11 SEPTRA should be discontinued. Urinalyses with careful microscopic examination and renal function tests should be performed during therapy, particularly for those patients with impaired renal function. Drug Interactions: In elderly patients concurrently receiving certain diuretics, primarily thiazides, an increased incidence of thrombocytopenia with purpura has been reported. In the literature, two cases of hyperkalemia in elderly patients have been reported after concomitant intake of trimethoprim/sulfamethoxazole and an angiotensin converting enzyme inhibitor. It has been reported that SEPTRA may prolong the prothrombin time in patients who are receiving the anticoagulant warfarin. This interaction should be kept in mind when SEPTRA is given to patients already on anticoagulant therapy, and the coagulation time should be reassessed. SEPTRA may inhibit the hepatic metabolism of phenytoin. SEPTRA, given at a common clinical dosage, increased the phenytoin half-life by 39% and decreased the phenytoin metabolic clearance rate by 27%. When administering these drugs concurrently, one should be alert for possible excessive phenytoin effect. Sulfonamides can also displace methotrexate from plasma protein binding sites, thus increasing free methotrexate concentrations. Drug/Laboratory Test Interactions: SEPTRA, specifically the trimethoprim component, can interfere with a serum methotrexate assay as determined by the competitive binding protein technique (CBPA) when a bacterial dihydrofolate reductase is used as the binding protein. No interference occurs, however, if methotrexate is measured by a radioimmunoassay (RIA). The presence of trimethoprim and sulfamethoxazole may also interfere with the Jaffé alkaline picrate reaction assay for This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda 12 creatinine, resulting in overestimations of about 10% in the range of normal values. Carcinogenesis, Mutagenesis, Impairment of Fertility: Carcinogenesis: Long-term studies in animals to evaluate carcinogenic potential have not been conducted with SEPTRA. Mutagenesis: Bacterial mutagenic studies have not been performed with sulfamethoxazole and trimethoprim in combination. Trimethoprim was demonstrated to be non-mutagenic in the Ames assay. In studies at two laboratories, no chromosomal damage was detected in cultured Chinese hamster ovary cells at concentrations approximately 500 times human plasma levels; at concentrations approximately 1,000 times human plasma levels in these same cells, a low level of chromosomal damage was induced at one of the laboratories. No chromosomal abnormalities were observed in cultured human leukocytes at concentrations of trimethoprim up to 20 times human steady-state plasma levels. No chromosomal effects were detected in peripheral lymphocytes of human subjects receiving 320 mg of trimethoprim in combination with up to 1,600 mg of sulfamethoxazole per day for as long as 112 weeks. Impairment of Fertility: No adverse effects on fertility or general reproductive performance were observed in rats given oral dosages as high as 70 mg/kg/day trimethoprim plus 350 mg/kg/day sulfamethoxazole. Pregnancy: Teratogenic Effects: Pregnancy Category C. In rats, oral doses of 533 mg/kg sulfamethoxazole or 200 mg/kg trimethoprim produced teratological effects manifested mainly as cleft palates. The highest dose which did not cause cleft palates in rats was 512 mg/kg sulfamethoxazole or 192 mg/kg trimethoprim when administered separately. In two studies in rats, no teratogenicity was observed when 512 mg/kg of sulfamethoxazole was used in combination with 128 mg/kg of trimethoprim. In one study, however, cleft palates were observed in one litter out of nine when 355 mg/kg of This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda 13 sulfamethoxazole was used in combination with 88 mg/kg of trimethoprim. In some rabbit studies, an overall increase in fetal loss (dead and resorbed and malformed conceptuses) was associated with doses of trimethoprim six times the human therapeutic dose. While there are no large, well-controlled studies on the use of trimethoprim and sulfameth oxazole in pregnant women, Brumfitt and Pursell, 5 in a retrospective study, reported the outcome of 186 pregnancies during which the mother received either placebo or trimethoprim and sulfamethoxazole. The incidence of congenital abnormalities was 4.5% (3 of 66) in those who received placebo and 3.3% (4 of 120) in those receiving trimethoprim and sulfamethoxazole. There were no abnormalities in the 10 children whose mothers received the drug during the first trimester. In a separate survey, Brumfitt and Pursell also found no congenital abnormalities in 35 children whose mothers had received oral trimethoprim and sulfamethoxazole at the time of conception or shortly thereafter. Because trimethoprim and sulfamethoxazole may interfere with folic acid metabolism, SEPTRA should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus. Nonteratogenic Effects: See CONTRAINDICATIONS section. Nursing Mothers: See CONTRAINDICATIONS section. Pediatric Use: SEPTRA is not recommended for pediatric patients younger than 2 months of age (see INDICATIONS AND USAGE and CONTRAINDICATIONS). Geriatric Use: Clinical studies of SEPTRA did not include sufficient numbers of subjects aged 65 and over to determine whether they respond differently from younger subjects. This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda 14 There may be an increase risk of severe adverse reactions in elderly patients, particularly when complicating conditions exist, e.g., impaired kidney and/or liver function, possible folate deficiency, or concomitant use of other drugs. Severe skin reactions, generalized bone marrow suppression (see WARNINGS and ADVERSE REACTIONS sections), a specific decrease in platelets (with or without purpura), and hyperkalemia are the most frequently reported severe adverse reactions in elderly patients. In those concurrently receiving certain diuretics, primarily thiazides, an increased incidence of thrombocytopenia with purpura has been reported. Increased digoxin blood levels can occur with concomitant Septra therapy, especially in elderly patients. Serum digoxin levels should be monitored. Hematological changes indicative of folic acid deficiency may occur in elderly patients. These effects are reversible by folinic acid therapy. Appropriate dosage adjustments should be made for patients with impaired kidney function and duration of use should be as short as possible to minimize risks of undesired reactions (see DOSAGE AND ADMINISTRATION section). The trimethoprim component of Septra may cause hyperkalemia when administered to patients with underlying disorders of potassium metabolism, with renal insufficiency, or when given concomitantly with drugs known to induce hyperkalemia, such as angiotensin converting enzyme inhibitors. Close monitoring of serum potassium is warranted in these patients. Discontinuation of Septra treatment is recommended to help lower potassium serum levels. Septra Tablets contain 1.8 mg (0.08 mEq) of sodium per tablet. Septra DS Tablets contain 3.6 mg (0.16 mEq) of sodium per tablet. Pharmacokinetics parameters for sulfamethoxazole were similar for geriatric subjects and younger adult subjects. The mean maximum serum trimethoprim concentration was higher and mean renal clearance of trimpethoprim was lower in geriatric subjects compared with younger subjects 3 (see CLINICAL PHARMACOLOGY: Geriatric Pharmacokinetcs). This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda 15 ADVERSE REACTIONS: The most common adverse effects are gastrointestinal disturbances (nausea, vomiting, anorexia) and allergic skin reactions (such as rash and urticaria). FATALITIES ASSOCIATED WITH THE ADMINISTRATION OF SULFONAMIDES, ALTHOUGH RARE, HAVE OCCURRED DUE TO SEVERE REACTIONS, INCLUDING STEVENS-JOHNSON SYNDROME, TOXIC EPIDERMAL NECROLYSIS, FULMINANT HEPATIC NECROSIS, AGRANULOCYTOSIS, APLASTIC ANEMIA, OTHER BLOOD DYSCRASIAS, AND HYPERSENSITIVITY OF THE RESPIRATORY TRACT (SEE WARNINGS).

Allergic: Stevens-Johnson syndrome, toxic epidermal necrolysis, anaphylaxis, allergic myocarditis, erythema multiforme, exfoliative dermatitis, angioedema, drug fever, chills, Henoch-Schönlein purpura, serum sickness-like syndrome, generalized allergic reactions, generalized skin eruptions, photosensitivity, conjunctival and scleral injection, pruritus, urticaria, and rash. In addition, periarteritis nodosa and systemic lupus erythematosus have been reported. Gastrointestinal: Hepatitis, including cholestatic jaundice and hepatic necrosis, elevation of serum transaminase and bilirubin, pseudomembranous enterocolitis, pancreatitis, stomatitis, glossitis, nausea, emesis, abdominal pain, diarrhea, anorexia. Genitourinary: Renal failure, interstitial nephritis, BUN and serum creatinine elevation, toxic nephrosis with oliguria and anuria, and crystalluria. Metabolic: Hyperkalemia, hyponatremia. Neurologic: Aseptic meningitis, convulsions, peripheral neuritis, ataxia, vertigo, tinnitus, headache. This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda 17 Chronic: Use of SEPTRA at high doses and/or for extended periods of time may cause bone marrow depression manifested as thrombocytopenia, leukopenia, and/or megaloblastic anemia. If signs of bone marrow depression occur, the patient should be given leucovorin; 5 to 15 mg leucovorin daily has been recommended by some investigators. DOSAGE AND ADMINISTRATION: Contraindicated in pediatric patients less than 2 months of age. Urinary Tract Infections and Shigellosis in Adults and Pediatric Patients and Acute Otitis Media in Pediatric Patients: Adults: The usual adult dosage in the treatment of urinary tract infections is one SEPTRA DS (double strength) tablet, two SEPTRA tablets, or four teaspoonfuls (20 mL) SEPTRA Suspension every 12 hours for 10 to 14 days. An identical daily dosage is used for 5 days in the treatment of shigellosis. Pediatric Patients: The recommended dose for pediatric patients with urinary tract infections or acute otitis media is 8 mg/kg trimethoprim and 40 mg/kg sulfamethoxazole per 24 hours, given in two divided doses every 12 hours for 10 days. An identical daily dosage is used for 5 days in the treatment of shigellosis. The following table is a guideline for the attainment of this dosage: Pediatric Patients: Two Months of Age or Older Weight Dose -- Every 12 Hours lb kg Teaspoonfuls Tablets 22 10 1 ( 5 mL) 44 20 2 (10 mL) 1 66 30 3 (15 mL) 11⁄2 88 40 4 (20 mL) 2(or 1 DS Tablet) This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda 16 Psychiatric: Hallucinations, depression, apathy, nervousness. Endocrine: The sulfonamides bear certain chemical similarities to some goitrogens, diuretics (acetazolamide and the thiazides), and oral hypoglycemic agents. Cross-sensitivity may exist with these agents. Diuresis and hypoglycemia have occurred rarely in patients receiving sulfonamides. Musculoskeletal: Arthralgia and myalgia. Respiratory System: Cough, shortness of breath, and pulmonary infiltrates (see WARNINGS). Miscellaneous: Weakness, fatigue, insomnia. OVERDOSAGE: Acute: The amount of a single dose of SEPTRA that is either associated with symptoms of overdosage or is likely to be life-threatening has not been reported. Signs and symptoms of overdosage reported with sulfonamides include anorexia, colic, nausea, vomiting, dizziness, headache, drowsiness, and unconsciousness. Pyrexia, hematuria, and crystalluria may be noted. Blood dyscrasias and jaundice are potential late manifestations of overdosage. Signs of acute overdosage with trimethoprim include nausea, vomiting, dizziness, headache, mental depression, confusion, and bone marrow depression. General principles of treatment include the institution of gastric lavage or emesis; forcing oral fluids; and the administration of intravenous fluids if urine output is low and renal function is normal. Acidification of the urine will increase renal elimination of trimethoprim. The patient should be monitored with blood counts and appropriate blood chemistries, including electrolytes. If a significant blood dyscrasia or jaundice occurs, specific therapy should be instituted for these complications. Peritoneal dialysis is not effective and hemodialysis is only moderately effective in eliminating trimethoprim and sulfamethoxazole. This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda 18 For Patients With Impaired Renal Function: When renal function is impaired, a reduced dosage should be employed using the following table: Creatinine Recommended Clearance Dosage (mL/min) Regimen Above 30 Use Standard Regimen 15-30 1⁄2 the Usual Regimen Below 15 Use Not Recommended Acute Exacerbations of Chronic Bronchitis in Adults: The usual adult dosage in the treatment of acute exacerbations of chronic bronchitis is one SEPTRA DS (double strength) tablet, two SEPTRA tablets, or four teaspoonfuls (20 mL) SEPTRA Suspension every 12 hours for 14 days. Travelers’ Diarrhea in Adults: For the treatment of travelers’ diarrhea, the usual adult dosage is one SEPTRA DS (double strength) tablet, two SEPTRA tablets, or four teaspoonfuls (20 mL) of SEPTRA Suspension every 12 hours for 5 days.

At 25°C, it dissolves to a 15 mg/mL solution in alcohol (95%). It is slightly soluble in water and insoluble in benzene. The pKa of Nalfon is a 4.5 at 25°C. CLINICAL PHARMACOLOGY This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda NDA 17-604/S-040 Page 4 Nalfon is a nonsteroidal, anti-inflammatory, antiarthritic drug that also possesses analgesic and antipyretic activities. Its exact mode of action is unknown, but it is thought that prostaglandin synthetase inhibition is involved. Nalfon has been shown to inhibit prostaglandin synthetase isolated from bovine seminal vesicles. Reproduction studies in rats have shown Nalfon to be associated with prolonged labor and difficult parturition when given during late pregnancy. Evidence suggests that this may be due to decreased uterine contractility resulting from the inhibition of prostaglandin synthesis. Its action is not mediated through the adrenal gland. Fenoprofen shows anti-inflammatory effects in rodents by inhibiting the development of redness and edema in acute inflammatory conditions and by reducing soft-tissue swelling and bone damage associated with chronic inflammation. It exhibits analgesic activity in rodents by inhibiting the writhing response caused by the introduction of an irritant into the peritoneal cavities of mice and by elevating pain thresholds that are related to pressure in edematous hindpaws of rats. In rats made febrile by the subcutaneous administration of brewer’s yeast, fenoprofen produces antipyretic action. These effects are characteristic of nonsteroidal, anti-inflammatory, antipyretic, analgesic drugs. The results in humans confirmed the anti-inflammatory and analgesic actions found in animals. The emergence and degree of erythemic response were measured in adult male volunteers exposed to ultraviolet irradiation. The effects of Nalfon, aspirin, and indomethacin were each compared with those of a placebo. All 3 drugs demonstrated antierythemic activity. In all patients with rheumatoid arthritis, the anti-inflammatory action of Nalfon has been evidenced by relief of pain, increase in grip strength, and reductions in joint swelling, duration of morning stiffness, and disease activity (as assessed by both the investigator and the patient). The anti-inflammatory action of Nalfon has also been evidenced by increased mobility (i.e., a decrease in the number of joints having limited motion). The use of Nalfon in combination with gold salts or corticosteroids has been studied in patients with rheumatoid arthritis. The studies, however, were inadequate in demonstrating whether further improvement is obtained by adding Nalfon to maintenance therapy with gold salts or steroids. Whether or not Nalfon used in conjunction with partially effective doses of a corticosteroid has a “steroid- sparing” effect is unknown. In patients with osteoarthritis, the anti-inflammatory and analgesic effects of Nalfon have been demonstrated by reduction in tenderness as a response to pressure and reductions in night pain, stiffness, swelling, and overall disease activity (as assessed by both the patient and the investigator). These effects have also been demonstrated by relief of pain with motion and at rest and increased range of motion in involved joints. In patients with rheumatoid arthritis and osteoarthritis, clinical studies have shown Nalfon to be comparable to aspirin in controlling the aforementioned measures of disease activity, but mild gastrointestinal reactions (nausea, dyspepsia) and tinnitus occurred less frequently in patients treated with Nalfon than in aspirin-treated patients. It is not known whether Nalfon causes less peptic ulceration than does aspirin. In patients with pain, the analgesic action of Nalfon has produced a reduction in pain intensity, an increase in pain relief, improvement in total analgesia scores, and a sustained analgesic effect. This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda NDA 17-604/S-040 Page 5 Under fasting conditions, Nalfon is rapidly absorbed, and peak plasma levels of 50 µg/mL are achieved within 2 hours after oral administration of 600 mg doses. Good dose proportionality was observed between 200 mg and 600 mg doses in fasting male volunteers. The plasma half-life is approximately 3 hours. About 90% of a single oral dose is eliminated within 24 hours as fenoprofen glucuronide and 4'- hydroxyfenoprofen glucuronide, the major urinary metabolites of fenoprofen. Fenoprofen is highly bound (99%) to albumin. The concomitant administration of antacid (containing both aluminum and magnesium hydroxide) does not interfere with absorption of Nalfon. There is less suppression of collagen-induced platelet aggregation with single doses of Nalfon than there is with aspirin. INDICATIONS AND USAGE Carefully consider the potential benefits and risks of Nalfon and other treatment options before deciding to use Nalfon. Use the lowest effective dose for the shortest duration consistent with individual patient treatment goals (see WARNINGS). Nalfon is indicated: • For relief of mild to moderate pain in adults. • For relief of the signs and symptoms of rheumatoid arthritis. • For relief of the signs and symptoms of osteoarthritis. CONTRAINDICATIONS Nalfon is contraindicated in patients who have shown hypersensitivity to fenoprofen calcium. Nalfon should not be given to patients who have experienced asthma, urticaria, or allergic-type reactions after taking aspirin or other NSAIDs. Severe, rarely fatal, anaphylactic-like reactions to NSAIDs have been reported in such patients (see WARNINGS – Anaphylactoid Reactions, and PRECAUTIONS – Preexisting Asthma). Nalfon is contraindicated for the treatment of peri-operative pain in the setting of coronary artery bypass graft (CABG) surgery (see WARNINGS). Nalfon is contraindicated in patients with a history of significantly impaired renal function. (see WARNINGS – Advanced Renal Disease). WARNINGS This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda NDA 17-604/S-040 Page 6 CARDIOVASCULAR EFFECTS Cardiovascular Thrombotic Events Clinical Trials of several COX-2 selective and nonselective NSAIDs of up to three years duration have shown an increased risk of serious cardiovascular (CV) thrombotic events, myocardial infarction, and stroke, which can be fatal. All NSAIDs, both COX-2 selective and nonselective, may gave a similar risk. Patients with know CV disease or risk factors for CV disease may be at greater risk. To minimize the potential risk for an adverse CV event in patients treated with an NSAID, the lowest effective dose should be used for the shortest duration possible. Physicians and patients should remain alert for the development of such event, even in the absence of previous CV symptoms. Patients should be informed about the signs and/or symptoms of serious CV events and the steps to take if they occur. There is no consistent evidence that concurrent us of aspirin mitigates the increased risk of serious CV thrombotic events associated with NSAID use. The concurrent use of aspirin and an NSAID does increase the risk of serious GI events (see GI WARNINGS). Two large, controlled, clinical trials of a COX-2 selective NSAID for the treatment of pain in the first 10-14 days following CABG surgery found an increased incidence of myocardial infarction and stroke (see CONTRAINDICATIONS). Hypertension NSAIDs, including Nalfon, can lead to onset of new hypertension or worsening of pre-existing hypertension, either of which may contribute to the increased incidence of CV events. Patients taking thiazides or loop diuretics may have impaired response to these therapies when taking NSAIDs. NSAIDs, including Nalfon, should be used with caution in patients with hypertension. Blood pressure (BP) should be monitored closely during the initiation of NSAID treatment and throughout the course of therapy. Congestive Heart Failure and Edema Fluid retention and edema have been observed in some patients taking NSAIDs. Nalfon should be used with caution in patients with fluid retention, compromised cardiac function or heart failure. The possibility of renal involvement should be considered. Gastrointestinal Effects – Risk of Ulceration, Bleeding, and Perforation NSAIDs, including Nalfon, can cause serious gastrointestinal (GI) adverse events including inflammation, bleeding, ulceration, and perforation of the stomach, small intestine, or large intestine, which can be fatal. These serious adverse events can occur at any time, with or without warning symptoms, in patients treated with NSAIDs. Only one in five patients, who develop a serious upper GI adverse event on NSAID therapy, is symptomatic. Upper GI ulcers, gross bleeding, or perforation caused by NSAIDs occur in approximately 1% of patients treated for 3-6 months, and in about 2-4% of patients treated for one year. These trends continue with longer duration of use, increasing the likelihood of developing a serious GI event at some time during the course of therapy. However, even short-term therapy is not without risk. NSAIDs should be prescribed with extreme caution in those with a prior history of ulcer disease or gastrointestinal bleeding. Patients with a prior history of peptic ulcer disease and/or gastrointestinal bleeding who use NSAIDs have a greater than 10-fold increased risk for developing a GI bleed compared to patients with neither of these risk factors. Other factors that increase the risk for GI bleeding in patients treated with NSAIDs include concomitant use of oral corticosteroids or anticoagulants, longer duration of NSAID therapy, smoking use of alcohol, older age, and poor general This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda NDA 17-604/S-040 Page 7 health status. Most spontaneous reports of fatal GI events are in elderly or debilitated patients and therefore, special care should be taken in treating this population. To minimize the potential risk for an adverse GI event in patients treated with an NSAID, the lowest effective dose should be used for the shortest possible duration. Patients and physicians should remain alert for signs and symptoms of GI ulceration and bleeding during NSAID therapy and promptly initiate additional evaluation and treatment if a serious GI adverse event is suspected. This should include discontinuation of the NSAID until a serious GI adverse event is ruled out. For high risk patients, alternate therapies that do not involve NSAIDs should be considered. Renal Effects Long-term administration of NSAIDs has resulted in renal papillary necrosis and other renal injury. Renal toxicity has also been seen in patients in whom renal prostaglandins have compensatory role in the maintenance of renal perfusion. In these patients, administration of a nonsteroidal anti- inflammatory drug may cause a dose-dependent reduction in prostaglandin formation and, secondarily, in renal blood flow, which my precipitate overt renal decomposition. Patients at greatest risk of this reaction are those with impaired renal function, heart failure, liver dysfunction, those taking diuretics and ACE inhibitors, and the elderly. Discontinuation of NSAID therapy is usually followed by recovery to the pretreatment state. Since Nalfon is primarily eliminated by the kidneys, patients with possibly compromised renal function (such as the elderly) should be monitored periodically, especially during long-term therapy. For such patients, it may be anticipated that a lower daily dosage will avoid excessive drug accumulation. Advanced Renal Disease No information is available from controlled clinical studies regarding the use of Nalfon in patients with advanced renal disease. Therefore, treatment with Nalfon is not recommended in these patients with advanced renal disease (see CONTRAINDICATIONS). If Nalfon therapy must be initiated, close monitoring of the patient's renal function is advisable. Genitourinary Tract NSAIDs including Nalfon can lead to onset of genitourinary tract problems. The most frequently reported problems have been episodes of dysuria, cystitis, hematuria, interstitial nephritis and nephrotic syndrome. This syndrome may be preceded by the appearance of fever, rash, arthralgia, oliguria, and azotemia and may progress to anuria. There may also be substantial proteinuria and, on renal biopsy, electron microscopy has shown foot process fusion and T-lymphocyte infiltration in the renal interstitium. Early recognition of the syndrome and withdrawal of the drug have been followed by rapid recovery. Administration of steroids and the use of dialysis have also been included in the treatment. Anaphylactoid Reactions As with other NSAIDs, anaphylactoid reactions may occur in patients without known prior exposure to Nalfon. Nalfon should not be given to patients with the aspirin triad. This symptom complex typically occurs in asthmatic patients who experience rhinitis with or without nasal polyps, or who exhibit severe, potentially fatal bronchospasm after taking aspirin or other NSAIDs (see CONTRAINDICATIONS and PRECAUTIONS - Preexisting Asthma). Emergency help should be sought in cases where an anaphylactoid reaction occurs. Skin Reactions NSAIDs, including Nalfon, can cause serious skin adverse events such as exfoliative This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda NDA 17-604/S-040 Page 8 dermatitis, Stevens-Johnson Syndrome (SJS), and toxic epidermal necrolysis (TEN), which can be fatal. These serious events may occur without warning. Patients should be informed about the signs and symptoms of serious skin manifestations and use of the drug should be discontinued at the first appearance of skin rash or any other sign of hypersensitivity. Pregnancy In late pregnancy, as with other NSAIDs, Nalfon should be avoided because it may cause premature closure of the ductus arteriosus. Ocular Studies to date have not shown changes in the eyes attributable to the administration of Nalfon. However, adverse ocular effects have been observed with other anti-inflammatory drugs. Eye examinations, therefore, should be performed if visual disturbances occur in patients taking Nalfon. Central Nervous System Caution should be exercised by patients whose activities require alertness if they experience CNS side effects while taking Nalfon. Hearing Since the safety of Nalfon has not been established in patients with impaired hearing, these patients should have periodic tests of auditory function during prolonged therapy with Nalfon. PRECAUTIONS General Nalfon cannot be expected to substitute for corticosteroids or to treat corticosteroid insufficiency. Abrupt discontinuation of corticosteroids may lead to disease exacerbation. Patients on prolonged corticosteroid therapy should have their therapy tapered slowly if a decision is made to discontinue corticosteroids. The pharmacological activity of Nalfon in reducing inflammation may diminish the utility of these diagnostic signs in detecting complications of presumed noninfectious, painful conditions. Hepatic Effects Borderline elevations of one or more liver tests may occur in up to 15% of patients taking NSAIDs including Nalfon. These laboratory abnormalities may progress, may remain unchanged, or may be transient with continuing therapy. Notable elevations of ALT or AST (approximately three or more times the upper limit of normal) have been reported in approximately 1% of patients in clinical trials with NSAIDs. In addition, rare cases of severe hepatic reactions, including jaundice and fatal fulminant hepatitis, liver necrosis and hepatic failure, some of them with fatal outcomes have been reported. A patient with symptoms and/or signs suggesting liver dysfunction, or in whom an abnormal liver test has occurred, should be evaluated for evidence of the development of a more severe hepatic reaction while on therapy with Nalfon. If clinical signs and symptoms consistent with liver disease develop, or if systemic manifestations occur (e.g., eosinophilia, rash, etc.), Nalfon should be discontinued. Hematological Effects Anemia is sometimes seen in patients receiving NSAIDs, including Nalfon. This may be due to fluid retention, occult or gross GI blood loss, or an incompletely described effect upon erythropoiesis. Patients on long-term treatment with NSAIDs, including Nalfon, should have their hemoglobin or This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda NDA 17-604/S-040 Page 9 hematocrit checked if they exhibit any signs or symptoms of anemia. NSAIDs inhibit platelet aggregation and have been shown to prolong bleeding time in some patients. Unlike aspirin, their effect on platelet function is quantitatively less, of shorter duration, and reversible. Patients receiving Nalfon who may be adversely affected by alterations in platelet function, such as those with coagulation disorders or patients receiving anticoagulants, should be carefully monitored. Preexisting Asthma Patients with asthma may have aspirin-sensitive asthma. The use of aspirin in patients with aspirin- sensitive asthma has been associated with severe bronchospasm which can be fatal. Since cross reactivity, including bronchospasm, between aspirin and other nonsteroidal anti-inflammatory drugs has been reported in such aspirin-sensitive patients, Nalfon should not be administered to patients with this form of aspirin sensitivity and should be used with caution in patients with preexisting asthma. Information for Patients Patients should be informed of the following information before initiating therapy with an NSAID and periodically during the course of ongoing therapy. Patients should also be encouraged to read the NSAID Medication Guide that accompanies each prescription dispensed. 1. Nalfon, like other NSAIDs, may cause serious CV side effects, such as MI or stroke, which may result in hospitalization and even death. Although serious CV events can occur without warning symptoms, patients should be alert for the signs and symptoms of chest pain, shortness of breath, weakness, slurring of speech, and should ask for medical advice when observing any indicative sign or symptoms. Patients should be apprised of the importance of this follow-up (see WARNINGS, Cardiovascular Effects). 2. Nalfon, like other NSAIDs, can cause GI discomfort and, rarely, serious GI side effects, such as ulcers and bleeding, which may result in hospitalization and even death. Although serious GI tract ulcerations and bleeding can occur without warning symptoms, patients should be alert for the signs and symptoms of ulcerations and bleeding, and should ask for medical advice when observing any indicative sign or symptoms including epigastric pain, dyspepsia, melena, and hematemesis. Patients should be apprised of the importance of this follow-up (see WARNINGS, Gastrointestinal Effects: Risk of Ulceration, Bleeding, and Perforation). 3. Nalfon, like other NSAIDs, can cause serious skin side effects such as exfoliative dermatitis, SJS, and TEN, which may result in hospitalizations and even death. Although serious skin reactions may occur without warning, patients should be alert for the signs and symptoms of skin rash and blisters, fever, or other signs of hypersensitivity such as itching, and should ask for medical advice when observing any indicative signs or symptoms. Patients should be advised to stop the drug immediately if they develop any type of rash and contact their physicians as soon as possible. 4. Patients should promptly report signs or symptoms of unexplained weight gain or edema to their physicians. 5. Patients should be informed of the warning signs and symptoms of hepatotoxicity (e.g., nausea, fatigue, lethargy, pruritus, jaundice, right upper quadrant tenderness, and "flu-like" symptoms). If these occur, patients should be instructed to stop therapy and seek immediate medical therapy. This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda NDA 17-604/S-040 Page 10 6. Patients should be informed of the signs of an anaphylactoid reaction (e.g. difficulty breathing, swelling of the face or throat). If these occur, patients should be instructed to seek immediate emergency help (see WARNINGS). 7. In late pregnancy, as with other NSAIDs, Nalfon should be avoided because it will may cause premature closure of the ductus arteriosus. Laboratory Tests Because serious GI tract ulcerations and bleeding can occur without warning symptoms, physicians should monitor for signs or symptoms of GI bleeding. Patients on long-term treatment with NSAIDs, should have their CBC and a chemistry profile checked periodically. If clinical signs and symptoms consistent with liver or renal disease develop, systemic manifestations occur (e.g., eosinophilia, rash, etc.) or if abnormal liver tests persist or worsen, Nalfon should be discontinued. Drug Interactions ACE-inhibitors Reports suggest that NSAIDs may diminish the antihypertensive effect of ACE-inhibitors. This interaction should be given consideration in patients taking NSAIDs concomitantly with ACE- inhibitors. Aspirin The coadministration of aspirin decreases the biologic half-life of fenoprofen because of an increase in metabolic clearance that results in a greater amount of hydroxylated fenoprofen in the urine. Although the mechanism of interaction between fenoprofen and aspirin is not totally known, enzyme induction and displacement of fenoprofen from plasma albumin binding sites are possibilities. As with other NSAIDs, concomitant administration of fenoprofen calcium and aspirin is not generally recommended because of the potential of increased adverse effects. Furosemide Diuretics Clinical studies, as well as post marketing observations, have shown that Nalfon can reduce the natriuretic effect-of furosemide and thiazides in some patients. This response has been attributed to inhibition of renal prostaglandin synthesis. During concomitant therapy with NSAIDs, the patient should be observed closely for signs of renal failure (see PRECAUTIONSWARNINGS, Renal Effects), as well as to assure diuretic efficacy. Lithium NSAIDs have produced an elevation of plasma lithium levels and a reduction in renal lithium clearance. The mean minimum lithium concentration increased 15% and the renal clearance was decreased by approximately 20%. These effects have been attributed to inhibition of renal prostaglandin synthesis by the NSAID. Thus, when NSAIDs and lithium are administered concurrently, subjects should be observed carefully for signs of lithium toxicity. Methotrexate NSAIDs have been reported to competitively inhibit methotrexate accumulation in rabbit kidney slices. This may indicate that they could enhance the toxicity of methotrexate. Caution should be used when NSAIDs are administered concomitantly with methotrexate. Warfarin This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda NDA 17-604/S-040 Page 11 The effects of warfarin and NSAIDs on GI bleeding are synergistic, such that users of both drugs together have a risk of serious GI bleeding higher than users of either drug alone. Phenobarbital Chronic administration of phenobarbital, a known enzyme inducer, may be associated with a decrease in the plasma half-life of fenoprofen. When phenobarbital is added to or withdrawn from treatment, dosage adjustment of Nalfon may be required. Plasma Protein Binding In vitro studies have shown that fenoprofen, because of it affinity for albumin, may displace from their binding sites other drugs that are also albumin bound, and this may lead to drug interaction. Theoretically, fenoprofen could likewise be displaced. Patients receiving hydantoins, sulfonamides, or sulfonylureas should be observed for increased activity of these drugs and, therefore, signs of toxicity from these drugs. Drug/Laboratory Test Interactions Amerlex-M kit assay values of total and free triiodothyronine in patients receiving Nalfon have been reported as falsely elevated on the basis of a chemical cross-reaction that directly interferes with the assay. Thyroid-stimulating hormone, total thyroxine, and thyrotropin-releasing hormone response are not affected. Pregnancy Teratogenic Effects. Pregnancy Category C. Reproductive studies conducted in rats and rabbits have not demonstrated evidence of developmental abnormalities. However, animal reproduction studies are not always predictive of human response. There are no adequate and well-controlled studies in pregnant women. Nalfon should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus. Nonteratogenic Effects Because of the known effects of nonsteroidal anti-inflammatory drugs on the fetal cardiovascular system (closure of ductus arteriosus), use during pregnancy (particularly late pregnancy) should be avoided. Labor and Delivery In rat studies with NSAIDs, as with other drugs known to inhibit prostaglandin synthesis, an increased incidence of dystocia, delayed parturition, and decreased pup survival occurred. The effects of Nalfon on labor and delivery in pregnant women are unknown. Nursing Mothers It is not known whether this drug is excreted in human milk. Because many drugs are excreted in human-milk and because of the potential for serious adverse reactions in nursing infants from Nalfon, a decision should be made whether to discontinue nursing or to discontinue the drug, taking into account the importance of the drug to the mother. Pediatric Use Safety and effectiveness in pediatric patients below the age of 18 havehas not been established. Geriatric Use This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda NDA 17-604/S-040 Page 12 As with any NSAIDs, caution should be exercised in treating the elderly (65 years and older). ADVERSE REACTIONS During clinical studies for rheumatoid arthritis, osteoarthritis, or mild to moderate pain and studies of pharmacokinetics, complaints were compiled from a checklist of potential adverse reactions, and the following data emerged. These encompass observations in 6,786 patients, including 188 observed for at least 52 weeks. For comparison, data are also presented from complaints received from the 266 patients who received placebo in these same trials. During short-term studies for analgesia, the incidence of adverse reactions was markedly lower than that seen in longer-term studies. INCIDENCE GREATER THAN 1% Probable Causal Relationship Digestive System—During clinical trials with Nalfon, the most common adverse reactions were gastrointestinal in nature and occurred in 20.8% of patients receiving Nalfon as compared to 16.9% of patients receiving placebo. In descending order of frequency, these reactions included dyspepsia (10.3%, Nalfon, vs. 2.3%, placebo), nausea (7.7% vs. 7.1%), constipation (7% vs. 1.5%), vomiting (2.6% vs. 1.9%), abdominal pain (2% vs. 1.1%), and diarrhea (1.8% vs. 4.1%). The drug was discontinued because of adverse gastrointestinal reactions in less than 2% of patients during premarketing studies. Nervous System —The most frequent adverse neurologic reactions were headache (8.7% treated vs. 7.5% placebo) and somnolence (8.5% vs. 6.4%). Dizziness (6.5% vs. 5.6%), tremor (2.2% vs. 0.4%), and confusion (1.4% vs. none) were noted less frequently. Nalfon was discontinued in less than 0.5% of patients because of these side effects during premarketing studies. Skin and Appendages—Increased sweating (4.6% vs. 0.4%), pruritus (4.2% vs. 0.8%), and rash (3.7% vs. 0.4%) were reported. Nalfon was discontinued in about 1% of patients because of an adverse effect related to the skin during premarketing studies. Special Senses—Tinnitus (4.5% vs. 0.4%), blurred vision (2.2% vs. none), and decreased hearing (1.6% vs. none) were reported. Nalfon was discontinued in less than 0.5% of patients because of adverse effects related to the special senses during premarketing studies. Cardiovascular—Palpitations (2.5% vs. 0.4%). Nalfon was discontinued in about 0.5% of patients because of adverse cardiovascular reactions during premarketing studies. Miscellaneous—Nervousness (5.7% vs. 1.5%), asthenia (5.4% vs. 0.4%), peripheral edema (5.0% vs. 0.4%), dyspnea (2.8% vs. none), fatigue (1.7% vs. 1.5%), upper respiratory infection (1.5% vs. 5.6%), and nasopharyngitis (1.2% vs. none). INCIDENCE LESS THAN 1% Probable Causal Relationship The following adverse reactions, occurring in less than 1% of patients, were reported in controlled clinical trials and voluntary reports made since Nalfon was initially marketed. The probability of a causal relationship exists between Nalfon and these adverse reactions: Digestive System—Gastritis, peptic ulcer with/without perforation, gastrointestinal hemorrhage, anorexia, flatulence, dry mouth, and blood in the stool. Increases in alkaline phosphatase, LDH, and SGOT, jaundice, and cholestatic hepatitis were observed (see PRECAUTIONS). This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda NDA 17-604/S-040 Page 13 Genitourinary Tract—Renal failure, dysuria, cystitis, hematuria, oliguria, azotemia, anuria, interstitial nephritis, nephrosis, and papillary necrosis (see WARNINGS). Hypersensitivity—Angioedema (angioneurotic edema). Hematologic—Purpura, bruising, hemorrhage, thrombocytopenia, hemolytic anemia, aplastic anemia, agranulocytosis, and pancytopenia. Miscellaneous—Anaphylaxis, urticaria, malaise, insomnia, and tachycardia. INCIDENCE LESS THAN 1% Causal Relationship Unknown Other reactions reported either in clinical trials or spontaneously, occurred in circumstances in which a causal relationship could not be established. However, with these rarely reported reactions, the possibility of such a relationship cannot be excluded. Therefore, these observations are listed to alert the physician. Skin and Appendages—Exfoliative dermatitis, toxic epidermal necrolysis, Stevens-Johnson syndrome, and alopecia. Digestive System—Aphthous ulcerations of the buccal mucosa, metallic taste, and pancreatitis. Cardiovascular—Atrial filbrillationfibrillation, pulmonary edema, electrocardiographic changes, and supraventricular tachycardia. Nervous System—Depression, disorientation, seizures, and trigeminal neuralgia. Special Senses—Burning tongue, diplopia, and optic neuritis. Miscellaneous—Personality change, lymphadenopathy, mastodynia, and fever. OVERDOSAGE Signs and Symptoms—Symptoms of overdose appear within several hours and generally involve the gastrointestinal and central nervous systems. They include dyspepsia, nausea, vomiting, abdominal pain, dizziness, headache, ataxia, tinnitus, tremor, drowsiness, and confusion. Hyperpyrexia, tachycardia, hypotension, and acute renal failure may occur rarely following overdose. Respiratory depression and metabolic acidosis have also been reported following overdose with certain NSAIDs. Treatment—To obtain up-to-date information about the treatment of overdose, a good resource is your certified Regional Poison Control Center. Telephone numbers of certified poison control centers are listed in the Physicians’ Desk Reference (PDR). In managing overdosage, consider the possibility of multiple drug overdoses, interaction among drugs, and unusual drug kinetics in your patient. Protect the patient’s airway and support ventilation and perfusion. Meticulously monitor and maintain, within acceptable limits, the patient’s vital signs, blood gases, serum electrolytes, etc. Absorption of drugs from the gastrointestinal tract may be decreased by giving activated charcoal, which, in many cases, is more effective than emesis or lavage; consider charcoal instead of or in addition to gastric emptying. Repeated doses of charcoal over time may hasten elimination of some drugs that have been absorbed. Safeguard the patient’s airway when employing gastric emptying or charcoal. Alkalinization of the urine, forced diuresis, peritoneal dialysis, hemodialysis, and charcoal hemoperfusion do not enhance systemic drug elimination. DOSAGE AND ADMINISTRATION Carefully consider the potential benefits and risks of Nalfon and other treatment options before deciding to use Nalfon. Use the lowest effective dose for the shortest duration This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda NDA 17-604/S-040 Page 14 consistent with individual patient treatment goals (see WARNINGS). After observing the response to initial therapy with Nalfon, the dose and frequency should be adjusted to suit an individual patient's needs. Analgesia For the treatment of mild to moderate pain, the recommended dosage is 200 mg given orally every 4 to 6 hours, as needed. Rheumatoid Arthritis and Osteoarthritis For the relief of rheumatoid arthritis or osteoarthritis the recommended dose is 300 to 600 mg given orally, 3 or 4 times a day. The dose should be tailored to the needs of the patient and may be increased or decreased depending on the severity of the symptoms. Dosage adjustments may be made after initiation of drug therapy or during exacerbations of the disease. Total daily dosage should not exceed 3,200 mg. Nalfon may be administered with meals or with milk. Although the total amount absorbed is not affected, peak blood levels are delayed and diminished. Patients with rheumatoid arthritis generally seem to require larger doses of Nalfon than do those with osteoarthritis. The smallest dose that yields acceptable control should be employed. Although improvement may be seen in a few days in many patients, an additional 2 to 3 weeks may be required to gauge the full benefits of therapy.

What is the most important information I should know about medicines called Non- Steroidal Anti-Inflammatory Drugs (NSAIDs)? NSAID medicines may increase the chance of a heart attack or stroke that can lead to death. This chance increases: • with longer use of NSAID medicines • in people who have heart disease NSAID medicines should never be used right before or after a heart surgery called a “coronary artery bypass graft (CABG).” NSAID medicines can cause ulcers and bleeding in the stomach and intestines at any time during treatment. Ulcers and bleeding: • can happen without warning symptoms • may cause death The chance of a person getting an ulcer or bleeding increases with: • taking medicines called “corticosteroids” and “anticoagulants” • longer use • smoking • drinking alcohol • older age • having poor health NSAID medicines should only be used: • exactly as prescribed • at the lowest dose possible for your treatment • for the shortest time needed What are Non-Steroidal Anti-Inflammatory Drugs (NSAIDs)? NSAID medicines are used to treat pain and redness, swelling, and heat (inflammation) from medical conditions such as: • different types of arthritis • menstrual cramps and other types of short-term pain This label may not be the latest approved by FDA.

Septra Tablets (trimethoprim and sulfamethoxazole tablets) Tablet Septra Ds Tablets (trimethoprim and sulfamethoxazole ds tablets) Tablet Septra Suspension (trimethoprim and sulfamethoxazole suspension) Suspension Septra Grape Suspension (trimethoprim and sulfamethoxazole grape suspension) Suspension To reduce the development of drug-resistant bacteria and maintain the effectiveness of SEPTRA and other antibacterial drugs, SEPTRA should be used only to treat or prevent infections that are proven or strongly suspected to be caused by bacteria. DESCRIPTION SEPTRA (trimethoprim and sulfamethoxazole) is a synthetic antibacterial combination product. Each SEPTRA Tablet contains 80 mg trimethoprim and 400 mg sulfamethoxazole and the inactive ingredients docusate sodium (0.4 mg per tablet), FD&C Red No. 40, magnesium stearate, povidone, and sodium starch glycolate. Each SEPTRA DS (double strength) Tablet contains 160 mg trimethoprim and 800 mg sulfamethoxazole and the inactive ingredients docusate sodium (0.8 mg per tablet), FD&C Red No. 40, magnesium stearate, povidone, and sodium starch glycolate. Each teaspoonful (5 mL) of SEPTRA Suspension contains 40 mg trimethoprim and 200 mg sulfamethoxazole and the inactive ingredients alcohol 0.26%, methylparaben 0.1% and sodium benzoate 0.1% (added as preservatives), carboxymethylcellulose sodium, citric acid, FD&C Red No. 40 and Yellow No. 6, flavor, glycerin, microcrystalline cellulose, polysorbate 80, saccharin sodium, and sorbitol. Each teaspoonful (5 mL) of SEPTRA Grape Suspension contains 40 mg trimethoprim and 200 mg sulfamethoxazole and the inactive ingredients alcohol 0.26%, methylparaben 0.1%, and sodium benzoate 0.1% (added as preservatives), carboxymethylcellulose sodium, citric acid, FD&C Red No. 40 and Blue No. 1, flavor, glycerin, microcrystalline cellulose, polysorbate 80, saccharin sodium, and sorbitol. Both tablet and suspension forms are for oral administration. Trimethoprim is 5-[(3,4,5-trimeth-oxyphenyl)methyl]-2,4- pyrimidinediamine. It is a white to light yellow, odorless, bitter compound with a molecular weight of 290.32, and the molecular formula C H N O . The structural formula is: Sulfamethoxazole is 4-amino-N-(5-methyl-3-isoxazolyl)benzenesulfonamide. It is an almost white, odorless, tasteless compound with a molecular weight of 253.28, and the molecular formula C H N O S. The structural formula is: CLINICAL PHARMACOLOGY SEPTRA is rapidly absorbed following oral administration. Both sulfamethoxazole and trimethoprim exist in the blood as unbound, protein-bound, and metabolized forms; sulfamethoxazole also exists as the conjugated form. The metabolism of sulfamethoxazole occurs predominately by N -acetylation, although the glucuronide conjugate has been identified. The principal metabolites of trimethoprim are Image from Drug Label Content Image from Drug Label Content 14 18 4 3 10 11 3 3 4 Page 1 of 16 SEPTRA® Tablets SEPTRA® DS (Double Strength) Tablets SEPTRA® Suspension SE... 9/5/2007 file://\\Cdsesub1\n17598\S_041\2007-03-23\labeling\spl\septra.xml This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda the 1- and 3-oxides and the 3’- and 4’-hydroxy derivatives. The free forms of sulfamethoxazole and trimethoprim are considered to be the therapeutically active forms. Approximately 44% of trimethoprim and 70% of sulfamethoxazole are bound to plasma proteins. The presence of 10 mg percent sulfamethoxazole in plasma decreases the protein binding of trimethoprim by an insignificant degree; trimethoprim does not influence the protein binding of sulfamethoxazole. Peak blood levels for the individual components occur 1 to 4 hours after oral administration. The mean serum half-lives of sulfamethoxazole and trimethoprim are 10 and 8 to 10 hours, respectively. However, patients with severely impaired renal function exhibit an increase in the half-lives of both components, requiring dosage regimen adjustment (see DOSAGE AND ADMINISTRATION). Detectable amounts of trimethoprim and sulfamethoxazole are present in the blood 24 hours after drug administration. During administration of 160 mg trimethoprim and 800 mg sulfamethoxazole b.i.d., the mean steady- state plasma concentration of trimethoprim was 1.72 mcg/mL. The steady-state minimal plasma levels of free and total sulfamethoxazole were 57.4 mcg/mL and 68.0 mcg/mL, respectively. These steady- state levels were achieved after 3 days of drug administration. Excretion of sulfamethoxazole and trimethoprim is primarily by the kidneys through both glomerular filtration and tubular secretion. Urine concentrations of both sulfamethoxazole and trimethoprim are considerably higher than are the concentrations in the blood. The average percentage of the dose recovered in urine from 0 to 72 hours after a single oral dose is 84.5% for total sulfonamide and 66.8% for free trimethoprim. Thirty percent of the total sulfonamide is excreted as free sulfamethoxazole, with the remaining as N -acetylated metabolite. When administered together as SEPTRA, neither sulfamethoxazole nor trimethoprim affects the urinary excretion pattern of the other. Both trimethoprim and sulfamethoxazole distribute to sputum, vaginal fluid, and middle ear fluid; trimethoprim also distributes to bronchial secretions, and both pass the placental barrier and are excreted in human milk. Geriatric Pharmacokinetics: The pharmacokinetics of sulfamethoxazole 800 mg and trimethoprim 160 mg were studied in 6 geriatric subjects (mean age: 78.6 years) and 6 young healthy subjects (mean age: 29.3 years) using a non-US approved formulation. Pharmacokinetic values for sulfamethoxazole in geriatric subjects were similar to those observed in young adult subjects. The mean renal clearance of trimethoprim was significantly lower in geriatric subjects compared with young adult subjects (19 mL/h/kg vs. 55 mL/h/kg). However, after normalizing by body weight, the apparent total body clearance of trimethoprim was an average 19% lower in geriatric subjects compared with young adult subjects. Microbiology: Sulfamethoxazole inhibits bacterial synthesis of dihydrofolic acid by competing with para-aminobenzoic acid (PABA). Trimethoprim blocks the production of tetrahydrofolic acid from dihydrofolic acid by binding to and reversibly inhibiting the required enzyme, dihydrofolate reductase. Thus, SEPTRA blocks two consecutive steps in the biosynthesis of nucleic acids and proteins essential to many bacteria. In vitro studies have shown that bacterial resistance develops more slowly with SEPTRA than with either trimethoprim or sulfamethoxazole alone. In vitro serial dilution tests have shown that the spectrum of antibacterial activity of SEPTRA includes the common urinary tract pathogens with the exception of Pseudomonas aeruginosa. The following organisms are usually susceptible: Escherichia coli, Klebsiella species, Enterobacter species, Morganella morganii, Proteus mirabilis, and indole-positive Proteus species including Proteus vulgaris. The usual spectrum of antimicrobial activity of SEPTRA includes bacterial pathogens isolated from 1 4 2 3 Page 2 of 16 SEPTRA® Tablets SEPTRA® DS (Double Strength) Tablets SEPTRA® Suspension SE... 9/5/2007 file://\\Cdsesub1\n17598\S_041\2007-03-23\labeling\spl\septra.xml This label may not be the latest approved by FDA.

Susceptibility Testing: The recommended quantitative disc susceptibility method may be used for estimating the susceptibility of bacteria to SEPTRA. With this procedure, a report from the laboratory of “Susceptible to trimethoprim and sulfamethoxazole” indicates that the infection is likely to respond to therapy with SEPTRA. If the infection is confined to the urine, a report of “Intermediate susceptibility to trimethoprim and sulfamethoxazole” also indicates that the infection is likely to respond. A report of “Resistant to trimethoprim and sulfamethoxazole” indicates that the infection is unlikely to respond to therapy with SEPTRA.

For current labeling information, please visit https://www.fda.gov/drugsatfda To reduce the development of drug-resistant bacteria and maintain the effectiveness of SEPTRA and other antibacterial drugs, SEPTRA should be used only to treat or prevent infections that are proven or strongly suspected to be caused by susceptible bacteria. When culture and susceptibility information are available, they should be considered in selecting or modifying antibacterial therapy. In the absence of such data, local epidemiology and susceptibility patterns may contribute to the empiric selection of therapy. Urinary Tract Infections: For the treatment of urinary tract infections due to susceptible strains of the following organisms: Escherichia coli, Klebsiella species, Enterobacter species, Morganella morganii, Proteus mirabilis, and Proteus vulgaris. It is recommended that initial episodes of uncomplicated urinary tract infections be treated with a single effective antibacterial agent rather than the combination. Acute Otitis Media: For the treatment of acute otitis media in pediatric patients due to susceptible strains of Streptococcus pneumoniae or Haemophilus influenzae when, in the judgment of the physician, SEPTRA offers some advantage over the use of other antimicrobial agents. To date, there is limited data on the safety of repeated use of SEPTRA in pediatric patients under two years of age. SEPTRA is not indicated for prophylactic or prolonged administration in otitis media at any age. Acute Exacerbations of Chronic Bronchitis in Adults: For the treatment of acute exacerbations of chronic bronchitis due to susceptible strains of Streptococcus pneumoniae or Haemophilus influenzae when, in the judgment of the physician, SEPTRA offers some advantage over the use of a single antimicrobial agent. Travelers’ Diarrhea in Adults: For the treatment of travelers’ diarrhea due to susceptible strains of enterotoxigenic E. coli. Shigellosis: For the treatment of enteritis caused by susceptible strains of Shigella flexneri and Shigella sonnei when antibacterial therapy is indicated. Pneumocystis Carinii Pneumonia: For the treatment of documented Pneumocystis carinii pneumonia. For prophylaxis against Pneumocystis carinii pneumonia in individuals who are immunosuppressed and considered to be at an increased risk of developing Pneumocystis carinii pneumonia. CONTRAINDICATIONS SEPTRA is contraindicated in patients with a known hypersensitivity to trimethoprim or sulfonamides and in patients with documented megaloblastic anemia due to folate deficiency. SEPTRA is also contraindicated in pregnant patients at term and in nursing mothers, because sulfonamides pass the placenta and are excreted in the milk and may cause kernicterus. SEPTRA is contraindicated in pediatric patients less than 2 months of age.

For current labeling information, please visit https://www.fda.gov/drugsatfda FATALITIES ASSOCIATED WITH THE ADMINISTRATION OF SULFONAMIDES, ALTHOUGH RARE, HAVE OCCURRED DUE TO SEVERE REACTIONS, INCLUDING STEVENS-JOHNSON SYNDROME, TOXIC EPIDERMAL NECROLYSIS, FULMINANT HEPATIC NECROSIS, AGRANULOCYTOSIS, APLASTIC ANEMIA, AND OTHER BLOOD DYSCRASIAS. SULFONAMIDES, INCLUDING SULFONAMIDE-CONTAINING PRODUCTS SUCH AS TRIMETHOPRIM/SULFAMETHOXAZOLE, SHOULD BE DISCONTINUED AT THE FIRST APPEARANCE OF SKIN RASH OR ANY SIGN OF ADVERSE REACTION. In rare instances, a skin rash may be followed by a more severe reaction, such as Stevens-Johnson syndrome, toxic epidermal necrolysis, hepatic necrosis, and serious blood disorder (see PRECAUTIONS). Clinical signs, such as rash, sore throat, fever, arthralgia, pallor, purpura, or jaundice may be early indications of serious reactions. Cough, shortness of breath, and pulmonary infiltrates are hypersensitivity reactions of the respiratory tract that have been reported in association with sulfonamide treatment. The sulfonamides should not be used for the treatment of group A beta-hemolytic streptococcal infections. In an established infection, they will not eradicate the streptococcus and, therefore, will not prevent sequelae such as rheumatic fever. Clostridium difficile associated diarrhea (CDAD) has been reported with use of nearly all antibacterial agents, including SEPTRA, and may range in severity from mild diarrhea to fatal colitis. Treatment with antibacterial agents alters the normal flora of the colon leading to overgrowth of C. difficile. C. difficile produces toxins A and B which contribute to the development of CDAD. Hypertoxin producing strains of C. difficile cause increased morbidity and mortality, as these infections can be refractory to antimicrobial therapy and may require colectomy. CDAD must be considered in all patients who present with diarrhea following antibiotic use. Careful medical history is necessary since CDAD has been reported to occur over two months after the administration of antibacterial agents. If CDAD is suspected or confirmed, ongoing antibiotic use not directed against C. difficile may need to be discontinued. Appropriate fluid and electrolyte management, protein supplementation, antibiotic treatment of C. difficile, and surgical evaluation should be instituted as clinically indicated. PRECAUTIONS General Prescribing SEPTRA in the absence of a proven or strongly suspected bacterial infection or a prophylactic indication is unlikely to provide benefit to the patient and increases the risk of the development of drug-resistant bacteria. SEPTRA should be given with caution to patients with impaired renal or hepatic function, to those with possible folate deficiency (e.g., the elderly, chronic alcoholics, patients receiving anticonvulsant therapy, patients with malabsorption syndrome, and patients in malnutrition states), and to those with severe allergy or bronchial asthma. In glucose-6-phosphate dehydrogenase-deficient individuals, hemolysis may occur. This reaction is frequently dose-related (see CLINICAL PHARMACOLOGY and DOSAGE AND ADMINISTRATION). Use in the Elderly: Page 5 of 16 SEPTRA® Tablets SEPTRA® DS (Double Strength) Tablets SEPTRA® Suspension SE... 9/5/2007 file://\\Cdsesub1\n17598\S_041\2007-03-23\labeling\spl\septra.xml This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda There may be an increased risk of severe adverse reactions in elderly patients, particularly when complicating conditions exist, e.g., impaired kidney and/or liver function, or concomitant use of other drugs. Severe skin reactions, or generalized bone marrow suppression (see WARNINGS and ADVERSE REACTIONS), or a specific decrease in platelets (with or without purpura) are the most frequently reported severe adverse reactions in elderly patients. In those concurrently receiving certain diuretics, primarily thiazides, an increased incidence of thrombocytopenia with purpura has been reported. Appropriate dosage adjustments should be made for patients with impaired kidney function (see DOSAGE AND ADMINISTRATION). Use in the Treatment of and Prophylaxis for Pneumocystis carinii Pneumonia in Patients with Acquired Immunodeficiency Syndrome (AIDS): The incidence of side effects, particularly rash, fever, leukopenia, and elevated aminotransferase (transaminase) values in AIDS patients who are being treated with SEPTRA for Pneumocystis carinii pneumonia has been reported to be greatly increased compared with the incidence normally associated with the use of SEPTRA in non-AIDS patients. The incidence of hyperkalemia and hyponatremia appears to be increased in AIDS patients receiving SEPTRA. Adverse effects are generally less severe in patients receiving SEPTRA for prophylaxis. A history of mild intolerance to SEPTRA in AIDS patients does not appear to predict intolerance of subsequent secondary prophylaxis. However, if a patient develops skin rash or any sign of adverse reaction, therapy with SEPTRA should be re-evaluated (see WARNINGS). The concomitant use of leucovorin with trimethoprim-sulfamethoxazole for the acute treatment of Pneumocystis carinii pneumonia in patients with HIV infection was associated with increased rates of treatment failure and morbidity in a placebo-controlled study. Information for Patients: Patients should be counseled that antibacterial drugs including SEPTRA should only be used to treat bacterial infections. They do not treat viral infections (e.g., the common cold). When SEPTRA is prescribed to treat a bacterial infection, patients should be told that although it is common to feel better early in the course of therapy, the medication should be taken exactly as directed. Skipping doses or not completing the full course of therapy may (1) decrease the effectiveness of the immediate treatment and (2) increase the likelihood that bacteria will develop resistance and will not be treatable with SEPTRA or other antibacterial drugs in the future. Patients should be instructed to maintain an adequate fluid intake in order to prevent crystalluria and stone formation. Diarrhea is a common problem caused by antibiotics which usually ends when the antibiotic is discontinued. Sometimes after starting treatment with antibiotics, patients can develop watery and bloody stools (with or without stomach cramps and fever) even as late as two or more months after having taken the last dose of the antibiotic. If this occurs, patients should contact their physician as soon as possible. Laboratory Tests: Complete blood counts should be done frequently in patients receiving SEPTRA; if a significant reduction in the count of any formed blood element is noted, SEPTRA should be discontinued. Urinalyses with careful microscopic examination and renal function tests should be performed during therapy, particularly for those patients with impaired renal function.

For current labeling information, please visit https://www.fda.gov/drugsatfda Drug Interactions: In elderly patients concurrently receiving certain diuretics, primarily thiazides, an increased incidence of thrombocytopenia with purpura has been reported. In the literature, two cases of hyperkalemia in elderly patients have been reported after concomitant intake of trimethoprim/sulfamethoxazole and an angiotensin converting enzyme inhibitor. It has been reported that SEPTRA may prolong the prothrombin time in patients who are receiving the anticoagulant warfarin. This interaction should be kept in mind when SEPTRA is given to patients already on anticoagulant therapy, and the coagulation time should be reassessed. SEPTRA may inhibit the hepatic metabolism of phenytoin. SEPTRA, given at a common clinical dosage, increased the phenytoin half-life by 39% and decreased the phenytoin metabolic clearance rate by 27%. When administering these drugs concurrently, one should be alert for possible excessive phenytoin effect. Sulfonamides can also displace methotrexate from plasma protein binding sites, thus increasing free methotrexate concentrations. Drug/Laboratory Test Interactions: SEPTRA, specifically the trimethoprim component, can interfere with a serum methotrexate assay as determined by the competitive binding protein technique (CBPA) when a bacterial dihydrofolate reductase is used as the binding protein. No interference occurs, however, if methotrexate is measured by a radioimmunoassay (RIA). The presence of trimethoprim and sulfamethoxazole may also interfere with the Jaffé alkaline picrate reaction assay for creatinine, resulting in overestimations of about 10% in the range of normal values. Carcinogenesis, Mutagenesis, Impairment of Fertility: Carcinogenesis: Long-term studies in animals to evaluate carcinogenic potential have not been conducted with SEPTRA. Mutagenesis: Bacterial mutagenic studies have not been performed with sulfamethoxazole and trimethoprim in combination. Trimethoprim was demonstrated to be non-mutagenic in the Ames assay. In studies at two laboratories, no chromosomal damage was detected in cultured Chinese hamster ovary cells at concentrations approximately 500 times human plasma levels; at concentrations approximately 1,000 times human plasma levels in these same cells, a low level of chromosomal damage was induced at one of the laboratories. No chromosomal abnormalities were observed in cultured human leukocytes at concentrations of trimethoprim up to 20 times human steady-state plasma levels. No chromosomal effects were detected in peripheral lymphocytes of human subjects receiving 320 mg of trimethoprim in combination with up to 1,600 mg of sulfamethoxazole per day for as long as 112 weeks. Impairment of Fertility: No adverse effects on fertility or general reproductive performance were observed in rats given oral dosages as high as 70 mg/kg/day trimethoprim plus 350 mg/kg/day sulfamethoxazole. Pregnancy Teratogenic Effects: Pregnancy Category C. In rats, oral doses of 533 mg/kg sulfamethoxazole or 200 mg/kg trimethoprim produced teratological effects manifested mainly as cleft palates. The highest dose which did not cause Page 7 of 16 SEPTRA® Tablets SEPTRA® DS (Double Strength) Tablets SEPTRA® Suspension SE... 9/5/2007 file://\\Cdsesub1\n17598\S_041\2007-03-23\labeling\spl\septra.xml This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda cleft palates in rats was 512 mg/kg sulfamethoxazole or 192 mg/kg trimethoprim when administered separately. In two studies in rats, no teratogenicity was observed when 512 mg/kg of sulfamethoxazole was used in combination with 128 mg/kg of trimethoprim. In one study, however, cleft palates were observed in one litter out of nine when 355 mg/kg of sulfamethoxazole was used in combination with 88 mg/kg of trimethoprim. In some rabbit studies, an overall increase in fetal loss (dead and resorbed and malformed conceptuses) was associated with doses of trimethoprim six times the human therapeutic dose. While there are no large, well-controlled studies on the use of trimethoprim and sulfamethoxazole in pregnant women, Brumfitt and Pursell, in a retrospective study, reported the outcome of 186 pregnancies during which the mother received either placebo or trimethoprim and sulfamethoxazole. The incidence of congenital abnormalities was 4.5% (3 of 66) in those who received placebo and 3.3% (4 of 120) in those receiving trimethoprim and sulfamethoxazole. There were no abnormalities in the 10 children whose mothers received the drug during the first trimester. In a separate survey, Brumfitt and Pursell also found no congenital abnormalities in 35 children whose mothers had received oral trimethoprim and sulfamethoxazole at the time of conception or shortly thereafter. Because trimethoprim and sulfamethoxazole may interfere with folic acid metabolism, SEPTRA should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus. Nonteratogenic Effects: See CONTRAINDICATIONS section. Nursing Mothers: See CONTRAINDICATIONS section. Pediatric Use: SEPTRA is not recommended for pediatric patients younger than 2 months of age (see INDICATIONS AND USAGE and CONTRAINDICATIONS). Geriatric Use: Clinical studies of SEPTRA did not include sufficient numbers of subjects aged 65 and over to determine whether they respond differently from younger subjects. There may be an increased risk of severe adverse reactions in elderly patients, particularly when complicating conditions exist, e.g., impaired kidney and/or liver function, possible folate deficiency, or concomitant use of other drugs. Severe skin reactions, generalized bone marrow suppression (see WARNINGS and ADVERSE REACTIONS sections), a specific decrease in platelets (with or without purpura), and hyperkalemia are the most frequently reported severe adverse reactions in elderly patients. In those concurrently receiving certain diuretics, primarily thiazides, an increased incidence of thrombocytopenia with purpura has been reported. Increased digoxin blood levels can occur with concomitant Septra therapy, especially in elderly patients. Serum digoxin levels should be monitored. Hematological changes indicative of folic acid deficiency may occur in elderly patients. These effects are reversible by folinic acid therapy. Appropriate dosage adjustments should be made for patients with impaired kidney function and duration of use should be as short as possible to minimize risks of undesired reactions (see DOSAGE AND ADMINISTRATION section). The trimethoprim component of Septra may cause hyperkalemia when administered to patients with underlying disorders of potassium metabolism, with renal insufficiency, or when given concomitantly with drugs known to induce hyperkalemia, such as angiotensin converting enzyme inhibitors. Close monitoring of serum potassium 6 Page 8 of 16 SEPTRA® Tablets SEPTRA® DS (Double Strength) Tablets SEPTRA® Suspension SE... 9/5/2007 file://\\Cdsesub1\n17598\S_041\2007-03-23\labeling\spl\septra.xml This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda is warranted in these patients. Discontinuation of Septra treatment is recommended to help lower potassium serum levels. Septra Tablets contain 1.8 mg (0.08 mEq) of sodium per tablet. Septra DS Tablets contain 3.6 mg (0.16 mEq) of sodium per tablet. Pharmacokinetics parameters for sulfamethoxazole were similar for geriatric subjects and younger adult subjects. The mean maximum serum trimethoprim concentration was higher and mean renal clearance of trimpethoprim was lower in geriatric subjects compared with younger subjects (see CLINICAL PHARMACOLOGY: Geriatric Pharmacokinetics). ADVERSE REACTIONS The most common adverse effects are gastrointestinal disturbances (nausea, vomiting, anorexia) and allergic skin reactions (such as rash and urticaria). FATALITIES ASSOCIATED WITH THE ADMINISTRATION OF SULFONAMIDES, ALTHOUGH RARE, HAVE OCCURRED DUE TO SEVERE REACTIONS, INCLUDING STEVENS-JOHNSON SYNDROME, TOXIC EPIDERMAL NECROLYSIS, FULMINANT HEPATIC NECROSIS, AGRANULOCYTOSIS, APLASTIC ANEMIA, OTHER BLOOD DYSCRASIAS, AND HYPERSENSITIVITY OF THE RESPIRATORY TRACT (SEE WARNINGS).

For current labeling information, please visit https://www.fda.gov/drugsatfda Endocrine: The sulfonamides bear certain chemical similarities to some goitrogens, diuretics (acetazolamide and the thiazides), and oral hypoglycemic agents. Cross-sensitivity may exist with these agents. Diuresis and hypoglycemia have occurred rarely in patients receiving sulfonamides. Musculoskeletal: Arthralgia and myalgia. Respiratory System: Cough, shortness of breath, and pulmonary infiltrates (see WARNINGS). Miscellaneous: Weakness, fatigue, insomnia. OVERDOSAGE Acute: The amount of a single dose of SEPTRA that is either associated with symptoms of overdosage or is likely to be life-threatening has not been reported. Signs and symptoms of overdosage reported with sulfonamides include anorexia, colic, nausea, vomiting, dizziness, headache, drowsiness, and unconsciousness. Pyrexia, hematuria, and crystalluria may be noted. Blood dyscrasias and jaundice are potential late manifestations of overdosage. Signs of acute overdosage with trimethoprim include nausea, vomiting, dizziness, headache, mental depression, confusion, and bone marrow depression. General principles of treatment include the institution of gastric lavage or emesis; forcing oral fluids; and the administration of intravenous fluids if urine output is low and renal function is normal. Acidification of the urine will increase renal elimination of trimethoprim. The patient should be monitored with blood counts and appropriate blood chemistries, including electrolytes. If a significant blood dyscrasia or jaundice occurs, specific therapy should be instituted for these complications. Peritoneal dialysis is not effective and hemodialysis is only moderately effective in eliminating trimethoprim and sulfamethoxazole. Chronic: Use of SEPTRA at high doses and/or for extended periods of time may cause bone marrow depression manifested as thrombocytopenia, leukopenia, and/or megaloblastic anemia. If signs of bone marrow depression occur, the patient should be given leucovorin; 5 to 15 mg leucovorin daily has been recommended by some investigators.

NALFONCI (fenoprofen calcium capsules, USP) 200 mg Rx onl y Cardiovascular Risk . NSAIDs may cause an increased risk of serious cardiovascular thrombotic events, myocardial infarction, and stroke, which can be fatal. This risk may increase with duration of use. Patients with cardiovascular disease or risk factors for cardiovascular disease may be at greater risk (See WARINGS) . . NalfonCI is contraindicated for the treatment of peri-operative pain in the setting of coronary artery bypass graft (CABG) surgery (see WARNINGS) . Gastrointestinal Risk . NSAIDs cause an increased risk of serious gastrointestinal adverse events including bleeding, ulceration, and perforation of stomach or intestines, which can be fatal. These events can occur at any time during use and wi thout warning symptoms. Elderly patients are at greater risk for serious gastrointestinal events (see WARINGS) . DESCRIPTION NalfonCI (fenoprofen calcium capsules, USP) is a nonsteroidal, anti- inflammatory, antiarthritic drug. Nalfon capsules contain fenoprofen calcium as the dihydrate in an amount equivalent to 200 mg (0.826 mmol) of fenoprofen. The capsules also contain cellulose, gelatin, iron oxides, silicone, titanium dioxide, and other inactive ingredients. Chemically, Nalfon is an arylacetic acid derivative. The structural formula is as follows: t This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda Benzeneacetic acid, a-methyl-3-phenoxy-, calcium salt dihydrate, (t)- Nalfon is a white crystalline powder that has the structural formula C30H26Ca06e2H20 representing a molecular weight of 558.65. At 25°C, it dissolves to a 15 mg/mL solution in alcohol (95%). It is slightly soluble in water and insoluble in benzene. The pKa of Nalfon is a 4.5 at 25°C. CLINICAL PHACOLOGY Nalfon is a nonsteroidal, anti-inflammatory, antiarthritic drug that also possesses analgesic and antipyretic activities. Its exact mode of action is unknown, but it is thought that prostaglandin synthetase inhibi tion is involved. Nalfon has been shown to inhibit prostaglandin synthetase isolated from bovine seminal vesicles. Reproduction studies in rats have shown Nalfon to be associated with prolonged labor and difficult parturition when given during late pregnancy. Evidence suggests that this may be due to decreased uterine contractility resulting from the inhibition of prostaglandin synthesis. Its action is not mediated through the adrenal gland. Fenoprofen shows anti-inflammatory effects in rodents by inhibiting the development of redness and edema in acute inflammatory conditions and by reducing soft-tissue swelling and bone damage associated with chronic inflammation. It exhibits analgesic activity in rodents by inhibiting the wri thing response caused by the introduction of an irri tant into the peritoneal cavities of mice and by elevating pain thresholds that are related to pressure in edematous hindpaws of rats. In rats made febrile by the subcutaneous administration of brewer's yeast, fenoprofen produces antipyretic action. These effects are characteristic of nonsteroidal, anti- inflammatory, antipyretic, analgesic drugs. The results in humans confirmed the anti-inflammatory and analgesic actions found in animals. The emergence and degree of erythemic response were measured in adult male volunteers exposed to ultraviolet irradiation. The effects of Nalfon, aspirin, and indomethacin were each compared with those of a placebo. All 3 drugs demonstrated antierythemic activity. In all patients with rheumatoid arthritis, the anti-inflammatory action of Nalfon has been evidenced by relief of pain, increase in grip strength, and reductions in joint swelling, duration of morning stiffness, and disease activity (as assessed by both the investigator and the patient). This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda The anti-inflammatory action of Nalfon has also been evidenced by increased mobility (i. e., a decrease in the number of joints having limited motion) . The use of Nalfon in combination with gold salts or corticosteroids has been studied in patients with rheumatoid arthritis. The studies, however, were inadequate in demonstrating whether further improvement is obtained by adding Nalfon to maintenance therapy with gold salts or steroids. Whether or not Nalfon used in conjunction with partially effective doses of a corticosteroid has a ~steroid-sparing" effect is unknown. In patients with osteoarthritis, the anti-inflammatory and analgesic effects of Nalfon have been demonstrated by reduction in tenderness as a response to pressure and reductions in night pain, stiffness, swelling, and overall disease activity (as assessed by both the patient and the investigator). These effects have also been demonstrated by relief of pain with motion and at rest and increased range of motion in involved joints. In patients with rheumatoid arthritis and osteoarthritis, clinical studies have shown Nalfon to be comparable to aspirin in controlling the aforementioned measures of disease activity, but mild gastrointestinal reactions (nausea, dyspepsia) and tinnitus occurred less frequently in patients treated with Nalfon than in aspirin-treated patients. It is not known whether Nalfon causes less peptic ulceration than does aspirin. In patients with pain, the analgesic action of Nalfon has produced a reduction in pain intensity, an increase in pain relief, improvement in total analgesia scores, and a sustained analgesic effect. Under fasting conditions, Nalfon is rapidly absorbed, and peak plasma levels of 50 ~g/mL are achieved within 2 hours after oral administration of 600 mg doses. Good dose proportionality was observed between 200 mg and 600 mg doses in fasting male volunteers. The plasma half-life is approximately 3 hours. About 90% of a single oral dose is eliminated within 24 hours as fenoprofen glucuronide and 4 i -hydroxyfenoprofen glucuronide, the major urinary metabolites of fenoprofen. Fenoprofen is highly bound (99%) to albumin. The concomitant administration of antacid (containing both aluminum and magnesium hydroxide) does not interfere with absorption of Nalfon. There is less suppression of collagen-induced platelet aggregation with single doses of Nalfon than there is with aspirin. l INDICATIONS AND USAGE Carefully consider the potential benefits and risks of Nalfon and other treatment options before deciding to use Nalfon. Use the lowest effective dose for the shortest duration consistent with individual patient treatment goal s (see WARINGS) . Nalfon is indicated: This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda . For relief of mild to moderate pain in adults. . For relief of the signs and symptoms of rheumatoid arthritis. . For relief of the signs and symptoms of osteoarthritis. CONTRAINDI CAT I ONS Nalfon is contraindicated in patients who have shown hypersensitivity to fenoprofen calcium. Nalfon should not be given to patients who have experienced asthma, urticaria, or allergic-type reactions after taking aspirin or other NSAIDs. Severe, rarely fatal, anaphylactic-like reactions to NSAIDs have been reported in such patients (see WARINGS - Anaphylactoid Reactions, and PRECAUTIONS - Preexisting Asthma) . Nalfon is contraindicated for the treatment of peri-operative pain in the setting of coronary artery bypass graft (CABG) surgery (see WARINGS) . Nalfon is contraindicated in patients with a history of significantly impaired renal function (see WARINGS - Advanced Renal Disease) . WARINGS Cardiovascular Effects Cardiovascular Thrombotic Events Clinical trials of several COX-2 selective and nonselective NSAIDs of up to three years duration have shown an increased risk of serious cardiovascular (CV) thrombotic events, myocardial infarction, and stroke, which can be fatal. All NSAIDs, both COX-2 selective and nonselective, may give a similar risk. Patients with known CV disease or risk factors for CV disease may be at greater risk. To minimize the potential risk for an adverse CV event in patients treated with an NSAID, the lowest effective dose should be used for the shortest duration possible. Physicians and patients should remain alert for the development of such events, even in the absence of previous CV symptoms. Patients should be informed about the signs and/or symptoms of serious CV events and the steps to take if they occur. There is no consistent evidence that concurrent use of aspirin mitigates the increased risk of serious CV thrombotic events associated with NSAID use. The concurrent use of aspirin and an NSAID does increase the risk of serious GI events (see GI WARINGS) . Two large, controlled, clinical trials of a COX-2 selective NSAID for the treatment of pain in the first 10-14 days following CABG surgery found an increased incidence of myocardial infarction and stroke (see CONTRAINDICATIONS) . Hypertension This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda NSAIDs, including Nalfon, can lead to onset of new hypertension or worsening of pre-existing hypertension, either of which may contribute to the increased incidence of CV events. Patients taking thiazides or loop diuretics may have impaired response to these therapies when taking NSAIDs. NSAIDs, including Nalfon, should be used with caution in patients with hypertension. Blood pressure (BP) should be monitored closely during the initiation of NSAID treatment and throughout the course of therapy. Congestive Heart Failure and Edema Fluid retention and edema have been observed in some patients taking NSAIDs. Nalfon should be used with caution in patients with fluid retention, compromised cardiac function or heart failure. The possibility of renal involvement should be considered. Gastrointestinal Effects - Risk of Ulceration, Bleeding, and Perforation NSAIDs, including Nalfon, can cause serious gastrointestinal (GI) adverse events including inflammation, bleeding, ulceration, and perforation of the stomach, small intestine, or large intestine, which can be fatal. These serious adverse events can occur at any time, with or without warning symptoms, in patients treated with NSAIDs. Only one in five patients, who develop a serious upper GI adverse event on NSAID therapy, is symptomatic. Upper GI ulcers, gross bleeding, or perforation caused by NSAIDs occur in approximately 1% of patients treated for 3 -6 months, and in about 2-4% of patients treated for one year. These trends continue with longer duration of use, increasing the likelihood of developing a serious GI event at some time during the course of therapy. However, even short- term therapy is not without risk. NSAIDs should be prescribed with extreme caution in those with a prior history of ulcer disease or gastrointestinal bleeding. Patients with a prior history of peptic ulcer disease and/or gastrointestinal bleeding who use NSAIDs have a greater than 10-fold increased risk for developing a GI bleed compared to patients with neither of these risk factors. Other factors that increase the risk for GI bleeding in patients treated with NSAIDs include concomitant use of oral corticosteroids or anticoagulants, longer duration of NSAID therapy, smoking, use of alcohol, older age, and poor general health status. Most spontaneous reports of fatal GI events are in elderly or debilitated patients and therefore, special care should be taken in treating this population. To minimize the potential risk for an adverse GI event in patients treated with a NSAID, the lowest effective dose should be used for the shortest possible duration. Patients and physicians should remain alert for signs and symptoms of GI ulceration and bleeding during NSAID therapy and promptly initiate additional evaluation and treatment if a serious GI adverse event is suspected. This should include discontinuation of the This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda NSAID until a serious GI adverse event is patients, alternate therapies that do not considered. Renal Effects Long-term administration of NSAIDs has resulted in renal papillary necrosis and other renal injury. Renal toxicity has also been seen in patients in whom renal prostaglandins have a compensatory role in the maintenance of renal perfusion. In these patients, administration of a nonsteroidal anti-inflammatory drug may cause a dose-dependent reduction in prostaglandin formation and, secondarily, in renal blood flow, which may precipitate overt renal decomposition. Patients at greatest risk of this reaction are those with impaired renal function, heart failure, liver dysfunction, those taking diuretics and ACE inhibitors, and the elderly. Discontinuation of NSAID therapy is usually followed by recovery to the pretreatment state. Advanced Renal Disease No information is available from controlled clinical studies regarding the use of Nalfon in patients with advanced renal disease. Therefore, treatment with Nalfon is not recommended in patients with advanced renal disease. (See CONTRAINDICATIONS) . Anaphylactoid Reactions As with other NSAIDs, anaphylactoid reactions may occur in patients without known prior exposure to Nalfon. Nalfon should not be given to patients with the aspirin triad. This symptom complex typically occurs in asthmatic patients who experience rhinitis with or without nasal polyps, or who exhibit severe, potentially fatal bronchospasm after taking aspirin or other NSAIDs (see CONTRAINDICATIONS and PRECAUTIONS - Preexisting Asthma) . Emergency help should be sought in cases where an anaphylactoid reaction ruled out. For invol ve NSAIDs high risk should be occurs. Skin Reactions NSAIDs, including Nalfon, can cause serious skin adverse events such as exfoliative dermatitis, Stevens-Johnson Syndrome (SJS) , and toxic epidermal necrolysis (TEN), which can be fatal. These serious events may occur wi thout warning. Patients should be informed about the signs and symptoms of serious skin manifestations and use of the drug should be discontinued at the first appearance of skin rash or any other sign of hypersensitivity. Pregnancy In late pregnancy, as with other NSAIDs, Nalfon should be avoided because it may cause premature closure of the ductus arteriosus. Ocular Studies to date have not shown changes in the eyes attributable to the administration of Nalfon. However, adverse ocular effects have been This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda observed with other anti-inflammatory drugs. Eye examinations, therefore, should be performed if visual disturbances occur in patients taking Nalfon. Central Nervous System Caution should be exercised by patients whose activities require alertness if they experience CNS side effects while taking Nalfon. Hearing Since the safety of Nalfon has not been established in patients with impaired hearing, these patients should have periodic tests of auditory function during prolonged therapy with Nalfon. PRECAUTIONS General Nalfon cannot be expected to substitute for corticosteroids or to treat corticosteroid insufficiency. Abrupt discontinuation of corticosteroids may lead to disease exacerbation. Patients on prolonged corticosteroid therapy should have their therapy tapered slowly if a decision is made to discontinue corticosteroids. The pharmacological activity of Nalfon in reducing inflammation may diminish the utility of these diagnostic signs in detecting complications of presumed noninfectious, painful conditions. Hepatic Effects Borderline elevations of one or more liver tests may occur in up to 15% of patients taking NSAIDs including Nalfon. These laboratory abnormalities may progress, may remain unchanged, or may be transient with continuing therapy. Notable elevations of ALT or AST (approximately three or more times the upper limit of normal) have been reported in approximately 1% of patients in clinical trials with NSAIDs. In addition, rare cases of severe hepatic reactions, including jaundice and fatal fulminant hepatitis, liver necrosis and hepatic failure, some of them with fatal outcomes have been reported. A patient with symptoms and/or signs suggesting liver dysfunction, or in whom an abnormal liver test has occurred, should be evaluated for evidence of the development of a more severe hepatic reaction while on therapy with Nalfon. If clinical signs and symptoms consistent with liver disease develop, or if systemic manifestations occur (e.g., eosinophilia, rash, etc.), Nalfon should be discontinued. l, Hematological Effects Anemia is sometimes seen in patients receiving NSAIDs, including Nalfon. This may be due to fluid retention, occult or gross GI blood loss, or an incompletely described effect upon erythropoiesis. Patients on long-term treatment with NSAIDs, including Nalfon, should have their hemoglobin or This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda hematocrit checked if they exhibit any signs or symptoms of anemia. NSAIDs inhibit platelet aggregation and have been shown to prolong bleeding time in some patients. Unlike aspirin, their effect on platelet function is quantitatively less, of shorter duration, and reversible. Patients receiving Nalfon who may be adversely affected by alterations in platelet function, such as those with coagulation disorders or patients receiving anticoagulants, should be carefully monitored. Preexisting Asthma Patients with asthma may have aspirin-sensitive asthma. The use of aspirin in patients with aspirin-sensitive asthma has been associated with severe bronchospasm which can be fatal. Since cross reactivity, including bronchospasm, between aspirin and other nonsteroidal anti - inflammatory drugs has been reported in such aspirin-sensitive patients, Nalfon should not be administered to patients with this form of aspirin sensitivity and should be used with caution in patients with preexisting asthma. Information for Patients Patients should be informed of the following information before initiating therapy with an NSAID and periodically during the course of ongoing therapy. Patients should also be encouraged to read the NSAID Medication Guide that accompanies each prescription dispensed. 1. Nalfon, like other NSAIDs, may cause serious CV side effects, such as MI or stroke, which may result in hospitalization and even death. Although serious CV events can occur without warning symptoms, patients should be alert for the signs and symptoms of chest pain, shortness of breath, weakness, slurring of speech, and should ask for medical advice when observing any indicative sign or symptoms. Patients should be apprised of the importance of this follow-up (see WARINGS, Cardiovascular Effects) . 2. Nalfon, like other NSAIDs, can cause GI discomfort and, rarely, serious GI side effects, such as ulcers and bleeding, which may result in hospitalization and even death. Although serious GI tract ulcerations and bleeding can occur without warning symptoms, patients should be alert for the signs and symptoms of ulcerations and bleeding, and should ask for medical advice when observing any indicative sign or symptoms including epigastric pain, dyspepsia, melena, and hematemesis. Patients should be apprised of the importance of this follow-up (see WARINGS, Gastrointestinal Effects Risk of Ulceration, Bleeding, and Perforation) . 3. Nalfon, like other NSAIDs, can cause serious skin side effects such as exfoliative dermatitis, SJS, and TEN, which may result in hospitalization and even death. Although serious skin reactions may occur without warning, patients should be alert for the signs and symptoms of This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda skin rash and blisters, fever, or other signs of hypersensitivity such as itching, and should ask for medical advice when observing any indicative signs or symptoms. Patients should be advised to stop the drug immediately if they develop any type of rash and contact their physicians as soon as possible. 4. Patients should promptly report signs or symptoms of unexplained weight gain or edema to their physicians. 5. Patients should be informed of the warning signs and symptoms of hepatotoxicity (e.g., nausea, fatigue, lethargy, pruritus, jaundice, right upper quadrant tenderness, and "flu-like" symptoms). If these occur, patients should be instructed to stop therapy and seek immediate medical therapy. 6. Patients should be informed of the signs of an anaphylactoid reaction (e.g. difficulty breathing, swelling of the face or throat). If these occur, patients should be instructed to seek immediate emergency help (see WARINGS) . 7. In late pregnancy, as with other NSAIDs, Nalfon should be avoided because it may cause premature closure of the ductus arteriosus. Laboratory Tests Because serious GI tract ulcerations and bleeding can occur without warning symptoms, physicians should monitor for signs or symptoms of GI bleeding. Patients on long-term treatment with NSAIDs should have their CBC and a chemistry profile checked periodically. If clinical signs and symptoms consistent with liver or renal disease develop, systemic manifestations occur (e.g., eosinophilia, rash, etc.) or if abnormal liver tests persist or worsen, Nalfon should be discontinued. Drug Interactions ACE-inhibitors Reports suggest that NSAIDs may diminish the antihypertensive effect of ACE-inhibitors. This interaction should be given consideration in patients taking NSAIDs concomitantly with ACE-inhibitors. Aspirin The coadministration of aspirin decreases the biologic half -life of fenoprofen because of an increase in metabolic clearance that results in a greater amount of hydroxylated fenoprofen in the urine. Al though the mechanism of interaction between fenoprofen and aspirin is not totally known, enzyme induction and displacement of fenoprofen from plasma albumin binding sites are possibil i ties. As with other NSAIDs, concomitant administration of fenoprofen calcium and aspirin is not generally recommended because of the potential of increased adverse effects. Diuretics i, This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda Clinical studies, as well as post marketing observations, have shown that Nalfon can reduce the natriuretic effect of furosemide and thiazides in some patients. This response has been attributed to inhibition of renal prostaglandin synthesis. During concomitant therapy with NSAIDs, the patient should be observed closely for signs of renal failure (see WARINGS, Renal Effects), as well as to assure diuretic efficacy. Li thi um NSAIDs have produced an elevation of plasma lithium levels and a reduction in renal lithium clearance. The mean minimum lithium concentration increased 15% and the renal clearance was decreased by approximately 20%. These effects have been attributed to inhibition of renal prostaglandin synthesis by the NSAID. Thus, when NSAIDs and lithium are administered concurrently, subj ects should be observed carefully for signs of lithium toxicity. Methotrexate NSAIDs have been reported to competitively inhibit methotrexate accumulation in rabbit kidney slices. This may indicate that they could enhance the toxicity of methotrexate. Caution should be used when NSAIDs are administered concomitantly with methotrexate. Warfarin The effects of warfarin and NSAIDs on GI bleeding are synergistic, such that users of both drugs together have a risk of serious GI bleeding higher than users of either drug alone. Phenobarbi tal Chronic administration of phenobarbital, a known enzyme inducer, may be associated with a decrease in the plasma half-life of fenoprofen. When phenobarbital is added to or withdrawn from treatment, dosage adjustment of Nalfon may be required. Plasma Protein Binding In vitro studies have shown that fenoprofen, because of its affinity for albumin, may displace from their binding sites other drugs that are also albumin bound, and this may lead to drug interactions. Theoretically, fenoprofen could likewise be displaced. Patients receiving hydantoins, sulfonamides, or sulfonylureas should be observed for increased activity of these drugs and, therefore, signs of toxicity from these drugs. Drug/Laboratory Test Interactions Amerlex-M kit assay values of total and free triiodothyronine in patients receiving Nalfon have been reported as falsely elevated on the basis of a chemical cross-reaction that directly interferes with the assay. Thyroid-stimulating hormone, total thyroxine, and thyrotropin-releasing hormone response are not affected. This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda Pregnancy Teratogenic Effects. Pregnancy Category C. Reproductive studies conducted in rats and rabbits have not demonstrated evidence of developmental abnormalities. However, animal reproduction studies are not always predictive of human response. There are no adequate and well-controlled studies in pregnant women. Nalfon should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus. Nonteratogenic Effects Because of the known effects of nonsteroidal anti-inflammatory drugs on the fetal cardiovascular system (closure of ductus arteriosus), use during pregnancy (particularly late pregnancy) should be avoided. Labor and Delivery In rat studies with NSAIDs, as with other drugs known to inhibit prostaglandin synthesis, an increased incidence of dystocia, delayed parturition, and decreased pup survival occurred. The effects of Nalfon on labor and delivery in pregnant women are unknown. Nursing Mothers It is not known whether this drug is excreted in human milk. Because many drugs are excreted in human milk and because of the potential for serious adverse reactions in nursing infants from Nalfon, a decision should be made whether to discontinue nursing or to discontinue the drug, taking into account the importance of the drug to the mother. Pediatric Use Safety and effectiveness in pediatric patients below the age of 18 have not been established. Geriatric Use As with any NSAIDs, caution should be exercised in treating the elderly (65 years and older) . ADVERSE REACTIONS During clinical studies for rheumatoid arthritis, osteoarthritis, or mild to moderate pain and studies of pharmacokinetics, complaints were compiled from a checklist of potential adverse reactions, and the following data emerged. These encompass observations in 6,786 patients, including 188 observed for at least 52 weeks. For comparison, data are also presented from complaints received from the 266 patients who received placebo in these same trials. During short-term studies for analgesia, the incidence of adverse reactions was markedly lower than that seen in longer-term studies. INCIDENCE GREATER THA 1% Probable Causal Relationship This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda Digestive System-During clinical trials with Nalfon, the most common adverse reactions were gastrointestinal in nature and occurred in 20.8% of patients recei ving Nalfon as compared to 16.9% of patients receiving placebo. In descending order of frequency, these reactions included dyspepsia (10.3% Nalfon, vs. 2.3%, placebo) , nausea (7.7% vs. 7.1%) , constipation (7% vs. 1. 5%) , vomiting (2.6% vs. 1. 9%) , abdominal pain (2% l vs. 1.1%), and diarrhea (1.8% vs. 4.1%). The drug was discontinued because of adverse gastrointestinal reactions in less than 2% of patients during premarketing studies. Nervous System -The most frequent adverse neurologic reactions were headache (8.7% vs. 7.5%) and somnolence (8.5% vs. 6.4%). Dizziness (6.5% vs. 5.6%), tremor (2.2% vs. 0.4%), and confusion (1.4% vs. none) were noted less frequently. Nalfon was discontinued in less than 0.5% of patients because of these side effects during premarketing studies. Skin and Appendages-Increased sweating (4.6% vs. 0.4%), pruritus (4.2% vs. 0.8%), and rash (3.7% vs. 0.4%) were reported. Nalfon was discontinued in about 1% of patients because of an adverse effect related to the skin during premarketing studies. Special Senses-Tinnitus (4.5% vs. 0.4%), blurred vision (2.2% vs. none), and decreased hearing (1.6% vs. none) were reported. Nalfon was discontinued in less than 0.5% of patients because of adverse effects related to the special senses during premarketing studies. Cardiovascular-Palpitations (2.5% vs. 0.4%). Nalfon was discontinued in about 0.5% of patients because of adverse cardiovascular reactions during premarketing studies. Miscellaneous-Nervousness (5.7% vs. 1.5%), asthenia (5.4% vs. 0.4%), peripheral edema (5.0% vs. 0.4%), dyspnea (2.8% vs. none), fatigue (1.7% vs. 1.5%), upper respiratory infection (1.5% vs. 5.6%), and nasopharyngitis ( 1 . 2 % vs. none). INCIDENCE LESS THA 1% Probable Causal Relationship The following adverse reactions, occurring in less than 1% of patients, were reported in controlled clinical trials and voluntary reports made since Nalfon was initially marketed. The probability of a causal relationship exists between Nalfon and these adverse reactions: Digestive System-Gastritis, peptic ulcer with/without perforation, gastrointestinal hemorrhage, anorexia, flatulence, dry mouth, and blood in the stool. Increases in alkal ine phosphatase, LDH, SGOT, jaundice, and cholestatic hepatitis were observed (see PRECAUTIONS) . Genitourinary Tract-Renal failure, dysuria, cystitis, hematuria, oliguria, azotemia, anuria, interstitial nephritis, nephrosis, and papillary necrosis (see WARINGS) .

Hematologic-Purpura, bruising, hemorrhage, thrombocytopenia, hemolytic anemia, aplastic anemia, agranulocytosis, and pancytopenia. MiscellaneouS-Anaphylaxis, urticaria, malaise, insomnia, and tachycardia. INCIDENCE LESS THA 1% Causal Relationship Unknown Other reactions, reported either in clinical trials or spontaneously, occurred in circumstances in which a causal relationship could not be established. However, with these rarely reported reactions, the possibility of such a relationship cannot be excluded. Therefore, these observations are listed to alert the physician. Skin and Appendages-Exfoliative dermatitis, toxic epidermal necrolysis, Stevens-Johnson syndrome, and alopecia. Digestive System-Aphthous ulcerations of the buccal mucosa, metallic taste, and pancreatitis. Cardiovascular-Atrial fibrillation, pulmonary edema, electrocardiographic changes, and supraventricular tachycardia. Nervous System-Depression, disorientation, seizures, and trigeminal neuralgia. Special Senses-Burning tongue, diplopia, and optic neuritis. Miscellaneous-Personality change, lymphadenopathy, mastodynia, and fever. OVERDOSAGE Signs and Symptoms-Symptoms of overdose appear within several hours and generally involve the gastrointestinal and central nervous systems. They include dyspepsia, nausea, vomiting, abdominal pain, dizziness, headache, ataxia, tinnitus, tremor, drowsiness, and confusion. Hyperpyrexia, tachycardia, hypotension, and acute renal failure may occur rarely following overdose. Respiratory depression and metabolic acidosis have also been reported following overdose with certain NSAIDs. Treatment-To obtain up-to-date information about the treatment of overdose, a good resource is your certified Regional Poison Control Center. Telephone numbers of certified poison control centers are listed in the Physicians' Desk Reference (PDR). In managing overdosage, consider the possibility of multiple drug overdoses, interaction among drugs, and unusual drug kinetics in your patient.

Repeated doses of charcoal over time may hasten elimination of some drugs that have been absorbed. Safeguard the patient's airway when employing gastric emptying or charcoal. Alkalinization of the urine, forced diuresis, hemodialysis, and charcoal hemoperfusion do not elimination. peritoneal dialysis, enhance systemic drug DOSAGE AN ADMINISTRATION Carefully consider the potential benefits and risks of Nalfon and other treatment options before deciding to use Nalfon. Use the lowest effective dose for the shortest duration consistent with individual patient treatment goals (see WARINGS) . After observing the response to initial therapy with Nalfon, the dose and frequency should be adjusted to suit an individual patient i s needs. Analgesia For the treatment of mild to moderate pain, the recommended dosage is 200 mg given orally every 4 to 6 hours, as needed. Rheumatoid Arthritis and Osteoarthritis For the relief of rheumatoid arthritis or osteoarthritis the recommended dose is 300 to 600 mg given orally, 3 or 4 times a day. The dose should be tailored to the needs of the patient and may be increased or decreased depending on the severity of the symptoms. Dosage adjustments may be made after initiation of drug therapy or during exacerbations of the disease. Total daily dosage should not exceed 3,200 mg. Nalfon may be administered with meals or with milk. Although the total amount absorbed is not affected, peak blood levels are delayed and diminished. Patients with rheumatoid arthritis generally seem to require larger doses of Nalfon than do those with osteoarthritis. The smallest dose that yields acceptable control should be employed. Al though improvement may be seen in a few days in many patients, an additional 2 to 3 weeks may be required to gauge the full benefits of therapy.

NALFON® (fenoprofen calcium capsules, USP) 200 mg and 400 mg Rx only Cardiovascular Risk • NSAIDs may cause an increased risk of serious cardiovascular thrombotic events, myocardial infarction, and stroke, which can be fatal. This risk may increase with duration of use. Patients with cardiovascular disease or risk factors for cardiovascular disease may be at greater risk (See WARNINGS). • Nalfon® is contraindicated for the treatment of peri-operative pain in the setting of coronary artery bypass graft (CABG) surgery (see WARNINGS). Gastrointestinal Risk • NSAIDs cause an increased risk of serious gastrointestinal adverse events including bleeding, ulceration, and perforation of stomach or intestines, which can be fatal. These events can occur at any time during use and without warning symptoms. Elderly patients are at greater risk for serious gastrointestinal events (see WARNINGS). DESCRIPTION Nalfon® (fenoprofen calcium capsules, USP) is a nonsteroidal, anti-inflammatory, antiarthritic drug. Nalfon capsules contain fenoprofen calcium as the dihydrate in an amount equivalent to 200 mg (0.826 mmol) or 400 mg (1.65 mmol) of fenoprofen. The 200 mg capsules contain cellulose, gelatin, iron oxides, silicone, titanium dioxide, and other inactive ingredients. The 400 mg capsules contain gelatin, sodium lauryl sulfate, iron oxide yellow, FD&C Blue 1, titanium dioxide, FD&C Red 40, crospovidone, talc, and magnesium stearate. Chemically, Nalfon is an arylacetic acid derivative. The structural formula is as follows: Structural Formula Benzeneacetic acid, α-methyl-3-phenoxy-, calcium salt dihydrate, (±)- This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda Nalfon is a white crystalline powder that has the structural formula C30H26CaO6•2H2O representing a molecular weight of 558.65. At 25°C, it dissolves to a 15 mg/mL solution in alcohol (95%). It is slightly soluble in water and insoluble in benzene. The pKa of Nalfon is a 4.5 at 25°C. CLINICAL PHARMACOLOGY Nalfon is a nonsteroidal, anti-inflammatory, antiarthritic drug that also possesses analgesic and antipyretic activities. Its exact mode of action is unknown, but it is thought that prostaglandin synthetase inhibition is involved. Results in humans demonstrate that fenoprofen has both anti-inflammatory and analgesic actions. The emergence and degree of erythemic response were measured in adult male volunteers exposed to ultraviolet irradiation. The effects of Nalfon, aspirin, and indomethacin were each compared with those of a placebo. All 3 drugs demonstrated antierythemic activity. In all patients with rheumatoid arthritis, the anti-inflammatory action of Nalfon has been evidenced by relief of pain, increase in grip strength, and reductions in joint swelling, duration of morning stiffness, and disease activity (as assessed by both the investigator and the patient). The anti-inflammatory action of Nalfon has also been evidenced by increased mobility (i.e., a decrease in the number of joints having limited motion). The use of Nalfon in combination with gold salts or corticosteroids has been studied in patients with rheumatoid arthritis. The studies, however, were inadequate in demonstrating whether further improvement is obtained by adding Nalfon to maintenance therapy with gold salts or steroids. Whether or not Nalfon used in conjunction with partially effective doses of a corticosteroid has a “steroid-sparing” effect is unknown. In patients with osteoarthritis, the anti-inflammatory and analgesic effects of Nalfon have been demonstrated by reduction in tenderness as a response to pressure and reductions in night pain, stiffness, swelling, and overall disease activity (as assessed by both the patient and the investigator). These effects have also been demonstrated by relief of pain with motion and at rest and increased range of motion in involved joints. In patients with rheumatoid arthritis and osteoarthritis, clinical studies have shown Nalfon to be comparable to aspirin in controlling the aforementioned measures of disease activity, but mild gastrointestinal reactions (nausea, dyspepsia) and tinnitus occurred less frequently in patients treated with Nalfon than in aspirin-treated patients. It is not known whether Nalfon causes less peptic ulceration than does aspirin. This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda In patients with pain, the analgesic action of Nalfon has produced a reduction in pain intensity, an increase in pain relief, improvement in total analgesia scores, and a sustained analgesic effect. Under fasting conditions, Nalfon is rapidly absorbed, and peak plasma levels of 50 µg/mL are achieved within 2 hours after oral administration of 600 mg doses. Good dose proportionality was observed between 200 mg and 600 mg doses in fasting male volunteers. The plasma half-life is approximately 3 hours. About 90% of a single oral dose is eliminated within 24 hours as fenoprofen glucuronide and 4'­ hydroxyfenoprofen glucuronide, the major urinary metabolites of fenoprofen. Fenoprofen is highly bound (99%) to albumin. The concomitant administration of antacid (containing both aluminum and magnesium hydroxide) does not interfere with absorption of Nalfon. There is less suppression of collagen-induced platelet aggregation with single doses of Nalfon than there is with aspirin. INDICATIONS AND USAGE Carefully consider the potential benefits and risks of Nalfon and other treatment options before deciding to use Nalfon. Use the lowest effective dose for the shortest duration consistent with individual patient treatment goals (see WARNINGS). Nalfon is indicated: • For relief of mild to moderate pain in adults. • For relief of the signs and symptoms of rheumatoid arthritis. • For relief of the signs and symptoms of osteoarthritis. CONTRAINDICATIONS Nalfon is contraindicated in patients who have shown hypersensitivity to fenoprofen calcium. Nalfon should not be given to patients who have experienced asthma, urticaria, or allergic-type reactions after taking aspirin or other NSAIDs. Severe, rarely fatal, anaphylactic-like reactions to NSAIDs have been reported in such patients (see WARNINGS – Anaphylactoid Reactions, and PRECAUTIONS – Preexisting Asthma). Nalfon is contraindicated for the treatment of peri-operative pain in the setting of coronary artery bypass graft (CABG) surgery (see WARNINGS). Nalfon is contraindicated in patients with a history of significantly impaired renal function (see WARNINGS – Advanced Renal Disease). This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda WARNINGS CARDIOVASCULAR EFFECTS Cardiovascular Thrombotic Events Clinical trials of several COX-2 selective and nonselective NSAIDs of up to three years duration have shown an increased risk of serious cardiovascular (CV) thrombotic events, myocardial infarction, and stroke, which can be fatal. All NSAIDs, both COX-2 selective and nonselective, may give a similar risk. Patients with known CV disease or risk factors for CV disease may be at greater risk. To minimize the potential risk for an adverse CV event in patients treated with an NSAID, the lowest effective dose should be used for the shortest duration possible. Physicians and patients should remain alert for the development of such events, even in the absence of previous CV symptoms. Patients should be informed about the signs and/or symptoms of serious CV events and the steps to take if they occur. There is no consistent evidence that concurrent use of aspirin mitigates the increased risk of serious CV thrombotic events associated with NSAID use. The concurrent use of aspirin and an NSAID does increase the risk of serious GI events (see GI WARNINGS). Two large, controlled, clinical trials of a COX-2 selective NSAID for the treatment of pain in the first 10-14 days following CABG surgery found an increased incidence of myocardial infarction and stroke (see CONTRAINDICATIONS). Hypertension NSAIDs, including Nalfon, can lead to onset of new hypertension or worsening of pre-existing hypertension, either of which may contribute to the increased incidence of CV events. Patients taking thiazides or loop diuretics may have impaired response to these therapies when taking NSAIDs. NSAIDs, including Nalfon, should be used with caution in patients with hypertension. Blood pressure (BP) should be monitored closely during the initiation of NSAID treatment and throughout the course of therapy. Congestive Heart Failure and Edema Fluid retention and edema have been observed in some patients taking NSAIDs. Nalfon should be used with caution in patients with fluid retention, compromised cardiac function or heart failure. The possibility of renal involvement should be considered. Gastrointestinal Effects – Risk of Ulceration, Bleeding, and Perforation NSAIDs, including Nalfon, can cause serious gastrointestinal (GI) adverse events including inflammation, bleeding, ulceration, and perforation of the stomach, small intestine, or large intestine, which can be fatal. These serious adverse events can occur at any time, with or without warning symptoms, in patients treated with NSAIDs. Only one in five patients, who develop a serious upper GI adverse event on This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda NSAID therapy, is symptomatic. Upper GI ulcers, gross bleeding, or perforation caused by NSAIDs occur in approximately 1% of patients treated for 3-6 months, and in about 2-4% of patients treated for one year. These trends continue with longer duration of use, increasing the likelihood of developing a serious GI event at some time during the course of therapy. However, even short-term therapy is not without risk. NSAIDs should be prescribed with extreme caution in those with a prior history of ulcer disease or gastrointestinal bleeding. Patients with a prior history of peptic ulcer disease and/or gastrointestinal bleeding who use NSAIDs have a greater than 10-fold increased risk for developing a GI bleed compared to patients with neither of these risk factors. Other factors that increase the risk for GI bleeding in patients treated with NSAIDs include concomitant use of oral corticosteroids or anticoagulants, longer duration of NSAID therapy, smoking, use of alcohol, older age, and poor general health status. Most spontaneous reports of fatal GI events are in elderly or debilitated patients and therefore, special care should be taken in treating this population. To minimize the potential risk for an adverse GI event in patients treated with a NSAID, the lowest effective dose should be used for the shortest possible duration. Patients and physicians should remain alert for signs and symptoms of GI ulceration and bleeding during NSAID therapy and promptly initiate additional evaluation and treatment if a serious GI adverse event is suspected. This should include discontinuation of the NSAID until a serious GI adverse event is ruled out. For high risk patients, alternate therapies that do not involve NSAIDs should be considered. Renal Effects Long-term administration of NSAIDs has resulted in renal papillary necrosis and other renal injury. Renal toxicity has also been seen in patients in whom renal prostaglandins have a compensatory role in the maintenance of renal perfusion. In these patients, administration of a nonsteroidal anti-inflammatory drug may cause a dose-dependent reduction in prostaglandin formation and, secondarily, in renal blood flow, which may precipitate overt renal decomposition. Patients at greatest risk of this reaction are those with impaired renal function, heart failure, liver dysfunction, those taking diuretics and ACE inhibitors, and the elderly. Discontinuation of NSAID therapy is usually followed by recovery to the pretreatment state. Advanced Renal Disease No information is available from controlled clinical studies regarding the use of Nalfon in patients with advanced renal disease. Therefore, treatment with Nalfon is not recommended in patients with advanced renal disease. (See CONTRAINDICATIONS). Anaphylactoid Reactions As with other NSAIDs, anaphylactoid reactions may occur in patients without known prior exposure to Nalfon. Nalfon should not be given to patients with the aspirin This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda triad. This symptom complex typically occurs in asthmatic patients who experience rhinitis with or without nasal polyps, or who exhibit severe, potentially fatal bronchospasm after taking aspirin or other NSAIDs (see CONTRAINDICATIONS and PRECAUTIONS - Preexisting Asthma). Emergency help should be sought in cases where an anaphylactoid reaction occurs. Skin Reactions NSAIDs, including Nalfon, can cause serious skin adverse events such as exfoliative dermatitis, Stevens-Johnson Syndrome (SJS), and toxic epidermal necrolysis (TEN), which can be fatal. These serious events may occur without warning. Patients should be informed about the signs and symptoms of serious skin manifestations and use of the drug should be discontinued at the first appearance of skin rash or any other sign of hypersensitivity. Pregnancy Starting at 30-weeks gestation, Nalfon and other NSAIDs should be avoided by pregnant women as premature closure of the ductus arteriosus in the fetus may occur. Ocular Studies to date have not shown changes in the eyes attributable to the administration of Nalfon. However, adverse ocular effects have been observed with other anti­ inflammatory drugs. Eye examinations, therefore, should be performed if visual disturbances occur in patients taking Nalfon. Central Nervous System Caution should be exercised by patients whose activities require alertness if they experience CNS side effects while taking Nalfon. Hearing Since the safety of Nalfon has not been established in patients with impaired hearing, these patients should have periodic tests of auditory function during prolonged therapy with Nalfon. PRECAUTIONS General Nalfon cannot be expected to substitute for corticosteroids or to treat corticosteroid insufficiency. Abrupt discontinuation of corticosteroids may lead to disease exacerbation. Patients on prolonged corticosteroid therapy should have their therapy tapered slowly if a decision is made to discontinue corticosteroids. The pharmacological activity of Nalfon in reducing inflammation may diminish the utility of these diagnostic signs in detecting complications of presumed noninfectious, painful conditions. This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda Hepatic Effects Borderline elevations of one or more liver tests may occur in up to 15% of patients taking NSAIDs including Nalfon. These laboratory abnormalities may progress, may remain unchanged, or may be transient with continuing therapy. Notable elevations of ALT or AST (approximately three or more times the upper limit of normal) have been reported in approximately 1% of patients in clinical trials with NSAIDs. In addition, rare cases of severe hepatic reactions, including jaundice and fatal fulminant hepatitis, liver necrosis and hepatic failure, some of them with fatal outcomes have been reported. A patient with symptoms and/or signs suggesting liver dysfunction, or in whom an abnormal liver test has occurred, should be evaluated for evidence of the development of a more severe hepatic reaction while on therapy with Nalfon. If clinical signs and symptoms consistent with liver disease develop, or if systemic manifestations occur (e.g., eosinophilia, rash, etc.), Nalfon should be discontinued. Hematological Effects Anemia is sometimes seen in patients receiving NSAIDs, including Nalfon. This may be due to fluid retention, occult or gross GI blood loss, or an incompletely described effect upon erythropoiesis. Patients on long-term treatment with NSAIDs, including Nalfon, should have their hemoglobin or hematocrit checked if they exhibit any signs or symptoms of anemia. NSAIDs inhibit platelet aggregation and have been shown to prolong bleeding time in some patients. Unlike aspirin, their effect on platelet function is quantitatively less, of shorter duration, and reversible. Patients receiving Nalfon who may be adversely affected by alterations in platelet function, such as those with coagulation disorders or patients receiving anticoagulants, should be carefully monitored. Preexisting Asthma Patients with asthma may have aspirin-sensitive asthma. The use of aspirin in patients with aspirin-sensitive asthma has been associated with severe bronchospasm which can be fatal. Since cross reactivity, including bronchospasm, between aspirin and other nonsteroidal anti-inflammatory drugs has been reported in such aspirin-sensitive patients, Nalfon should not be administered to patients with this form of aspirin sensitivity and should be used with caution in patients with preexisting asthma. Information for Patients Patients should be informed of the following information before initiating therapy with an NSAID and periodically during the course of ongoing therapy. Patients should also be encouraged to read the NSAID Medication Guide that accompanies each prescription dispensed. 1. Nalfon, like other NSAIDs, may cause serious CV side effects, such as MI or stroke, which may result in hospitalization and even death. Although serious CV events can occur without warning symptoms, patients should be alert for the signs and symptoms of chest pain, shortness of breath, weakness, slurring of speech, This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda and should ask for medical advice when observing any indicative sign or symptoms. Patients should be apprised of the importance of this follow-up (see WARNINGS, Cardiovascular Effects). 2. Nalfon, like other NSAIDs, can cause GI discomfort and, rarely, serious GI side effects, such as ulcers and bleeding, which may result in hospitalization and even death. Although serious GI tract ulcerations and bleeding can occur without warning symptoms, patients should be alert for the signs and symptoms of ulcerations and bleeding, and should ask for medical advice when observing any indicative sign or symptoms including epigastric pain, dyspepsia, melena, and hematemesis. Patients should be apprised of the importance of this follow-up (see WARNINGS, Gastrointestinal Effects – Risk of Ulceration, Bleeding, and Perforation). 3. Nalfon, like other NSAIDs, can cause serious skin side effects such as exfoliative dermatitis, SJS, and TEN, which may result in hospitalization and even death. Although serious skin reactions may occur without warning, patients should be alert for the signs and symptoms of skin rash and blisters, fever, or other signs of hypersensitivity such as itching, and should ask for medical advice when observing any indicative signs or symptoms. Patients should be advised to stop the drug immediately if they develop any type of rash and contact their physicians as soon as possible. 4. Patients should promptly report signs or symptoms of unexplained weight gain or edema to their physicians. 5. Patients should be informed of the warning signs and symptoms of hepatotoxicity (e.g., nausea, fatigue, lethargy, pruritus, jaundice, right upper quadrant tenderness, and "flu-like" symptoms). If these occur, patients should be instructed to stop therapy and seek immediate medical therapy. 6. Patients should be informed of the signs of an anaphylactoid reaction (e.g. difficulty breathing, swelling of the face or throat). If these occur, patients should be instructed to seek immediate emergency help (see WARNINGS). 7. Starting at 30-weeks gestation, Nalfon and other NSAIDs should be avoided by pregnant women as premature closure of the ductus arteriosus in the fetus may occur. Laboratory Tests Because serious GI tract ulcerations and bleeding can occur without warning symptoms, physicians should monitor for signs or symptoms of GI bleeding. Patients on long-term treatment with NSAIDs should have their CBC and a chemistry profile checked periodically. If clinical signs and symptoms consistent with liver or renal disease develop, systemic manifestations occur (e.g., eosinophilia, rash, etc.) or if abnormal liver tests persist or worsen, Nalfon should be discontinued. Drug Interactions ACE-inhibitors This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda Reports suggest that NSAIDs may diminish the antihypertensive effect of ACE- inhibitors. This interaction should be given consideration in patients taking NSAIDs concomitantly with ACE-inhibitors. Aspirin The coadministration of aspirin decreases the biologic half-life of fenoprofen because of an increase in metabolic clearance that results in a greater amount of hydroxylated fenoprofen in the urine. Although the mechanism of interaction between fenoprofen and aspirin is not totally known, enzyme induction and displacement of fenoprofen from plasma albumin binding sites are possibilities. As with other NSAIDs, concomitant administration of fenoprofen calcium and aspirin is not generally recommended because of the potential of increased adverse effects. Diuretics Clinical studies, as well as post marketing observations, have shown that Nalfon can reduce the natriuretic effect of furosemide and thiazides in some patients. This response has been attributed to inhibition of renal prostaglandin synthesis. During concomitant therapy with NSAIDs, the patient should be observed closely for signs of renal failure (see WARNINGS, Renal Effects), as well as to assure diuretic efficacy. Lithium NSAIDs have produced an elevation of plasma lithium levels and a reduction in renal lithium clearance. The mean minimum lithium concentration increased 15% and the renal clearance was decreased by approximately 20%. These effects have been attributed to inhibition of renal prostaglandin synthesis by the NSAID. Thus, when NSAIDs and lithium are administered concurrently, subjects should be observed carefully for signs of lithium toxicity. Methotrexate NSAIDs have been reported to competitively inhibit methotrexate accumulation in rabbit kidney slices. This may indicate that they could enhance the toxicity of methotrexate. Caution should be used when NSAIDs are administered concomitantly with methotrexate. Warfarin The effects of warfarin and NSAIDs on GI bleeding are synergistic, such that users of both drugs together have a risk of serious GI bleeding higher than users of either drug alone. Phenobarbital Chronic administration of phenobarbital, a known enzyme inducer, may be associated with a decrease in the plasma half-life of fenoprofen. When phenobarbital is added to or withdrawn from treatment, dosage adjustment of Nalfon may be required. Plasma Protein Binding This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda In vitro studies have shown that fenoprofen, because of its affinity for albumin, may displace from their binding sites other drugs that are also albumin bound, and this may lead to drug interactions. Theoretically, fenoprofen could likewise be displaced. Patients receiving hydantoins, sulfonamides, or sulfonylureas should be observed for increased activity of these drugs and, therefore, signs of toxicity from these drugs. Drug/Laboratory Test Interactions Amerlex-M kit assay values of total and free triiodothyronine in patients receiving Nalfon have been reported as falsely elevated on the basis of a chemical cross- reaction that directly interferes with the assay. Thyroid-stimulating hormone, total thyroxine, and thyrotropin-releasing hormone response are not affected. Carcinogenesis, Mutagenesis, and Impairment of Fertility Long-term studies in animals have not been conducted to evaluate the carcinogenic potential of fenoprofen. Studies have not been conducted to determine the effect of fenoprofen on mutagenicity or fertility. Pregnancy Teratogenic Effects. Pregnancy Category C Prior to 30-Weeks Gestation; Category D starting at 30-Weeks Gestation. Starting at 30-weeks gestation, Nalfon and other NSAIDs should be avoided by pregnant women as premature closure of the ductus arteriosus in the fetus may occur. Nalfon can cause fetal harm when administered to a pregnant woman starting at 30­ weeks gestation. If this drug is used during this time period in pregnancy, the patient should be apprised of the potential hazard to a fetus. There are no adequate and well- controlled studies in pregnant women. Prior to 30-weeks gestation, Nalfon should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus. Reproductive studies conducted in rats and rabbits have not demonstrated evidence of developmental abnormalities when given daily oral doses of 50 or 100 mg/kg fenoprofen calcium, respectively (0.15 and 0.6 times the maximum human daily dose of 3200 mg based on body surface area comparisons). However, animal reproduction studies are not always predictive of human response. Nonteratogenic Effects Because of the known effects of nonsteroidal anti-inflammatory drugs on the fetal cardiovascular system (closure of ductus arteriosus), use during pregnancy (particularly late pregnancy) should be avoided. Labor and Delivery The effects of Nalfon on labor and delivery in pregnant women are unknown. In rat studies, maternal exposure to NSAIDs, as with other drugs known to inhibit This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda prostaglandin synthesis, increased the incidence of dystocia, delayed parturition, and decreased pup survival. Nursing Mothers It is not known whether this drug is excreted in human milk. Because many drugs are excreted in human milk and because of the potential for serious adverse reactions in nursing infants from Nalfon, a decision should be made whether to discontinue nursing or to discontinue the drug, taking into account the importance of the drug to the mother. Pediatric Use Safety and effectiveness in pediatric patients below the age of 18 have not been established. Geriatric Use As with any NSAIDs, caution should be exercised in treating the elderly (65 years and older). ADVERSE REACTIONS During clinical studies for rheumatoid arthritis, osteoarthritis, or mild to moderate pain and studies of pharmacokinetics, complaints were compiled from a checklist of potential adverse reactions, and the following data emerged. These encompass observations in 6,786 patients, including 188 observed for at least 52 weeks. For comparison, data are also presented from complaints received from the 266 patients who received placebo in these same trials. During short-term studies for analgesia, the incidence of adverse reactions was markedly lower than that seen in longer-term studies. Adverse Drug Reactions Reported in ≥1% of Patients During Clinical Trials Digestive System—During clinical trials with Nalfon, the most common adverse reactions were gastrointestinal in nature and occurred in 20.8% of patients receiving Nalfon as compared to 16.9% of patients receiving placebo.

Dizziness (6.5% vs. 5.6%), tremor (2.2% vs. 0.4%), and confusion (1.4% vs. none) were noted less frequently. Nalfon was discontinued in less than 0.5% of patients because of these side effects during premarketing studies. This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda Skin and Appendages—Increased sweating (4.6% vs. 0.4%), pruritus (4.2% vs. 0.8%), and rash (3.7% vs. 0.4%) were reported. Nalfon was discontinued in about 1% of patients because of an adverse effect related to the skin during premarketing studies. Special Senses—Tinnitus (4.5% vs. 0.4%), blurred vision (2.2% vs. none), and decreased hearing (1.6% vs. none) were reported. Nalfon was discontinued in less than 0.5% of patients because of adverse effects related to the special senses during premarketing studies. Cardiovascular—Palpitations (2.5% vs. 0.4%). Nalfon was discontinued in about 0.5% of patients because of adverse cardiovascular reactions during premarketing studies.

Miscellaneous—Anaphylaxis, urticaria, malaise, insomnia, tachycardia, personality change, lymphadenopathy, mastodynia, and fever. This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda OVERDOSAGE Signs and Symptoms—Symptoms of overdose appear within several hours and generally involve the gastrointestinal and central nervous systems. They include dyspepsia, nausea, vomiting, abdominal pain, dizziness, headache, ataxia, tinnitus, tremor, drowsiness, and confusion. Hyperpyrexia, tachycardia, hypotension, and acute renal failure may occur rarely following overdose. Respiratory depression and metabolic acidosis have also been reported following overdose with certain NSAIDs. Treatment—To obtain up-to-date information about the treatment of overdose, a good resource is your certified Regional Poison Control Center. Telephone numbers of certified poison control centers are listed in the Physicians’ Desk Reference (PDR). In managing overdosage, consider the possibility of multiple drug overdoses, interaction among drugs, and unusual drug kinetics in your patient. Protect the patient’s airway and support ventilation and perfusion. Meticulously monitor and maintain, within acceptable limits, the patient’s vital signs, blood gases, serum electrolytes, etc. Absorption of drugs from the gastrointestinal tract may be decreased by giving activated charcoal, which, in many cases, is more effective than lavage; consider charcoal instead of or in addition to gastric emptying. Repeated doses of charcoal over time may hasten elimination of some drugs that have been absorbed. Safeguard the patient’s airway when employing gastric emptying or charcoal. Alkalinization of the urine, forced diuresis, peritoneal dialysis, hemodialysis, and charcoal hemoperfusion do not enhance systemic drug elimination. DOSAGE AND ADMINISTRATION Carefully consider the potential benefits and risks of Nalfon and other treatment options before deciding to use Nalfon. Use the lowest effective dose for the shortest duration consistent with individual patient treatment goals (see WARNINGS). After observing the response to initial therapy with Nalfon, the dose and frequency should be adjusted to suit an individual patient's needs. Analgesia For the treatment of mild to moderate pain, the recommended dosage is 200 mg given orally every 4 to 6 hours, as needed. Rheumatoid Arthritis and Osteoarthritis For the relief of signs and symptoms of rheumatoid arthritis or osteoarthritis the recommended dose is 400 to 600 mg given orally, 3 or 4 times a day. The dose should be tailored to the needs of the patient and may be increased or decreased depending on the severity of the symptoms. Dosage adjustments may be made after initiation of drug therapy or during exacerbations of the disease. Total daily dosage should not exceed 3,200 mg. This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda Nalfon may be administered with meals or with milk. Although the total amount absorbed is not affected, peak blood levels are delayed and diminished. Patients with rheumatoid arthritis generally seem to require larger doses of Nalfon than do those with osteoarthritis. The smallest dose that yields acceptable control should be employed. Although improvement may be seen in a few days in many patients, an additional 2 to 3 weeks may be required to gauge the full benefits of therapy.

c o mp an y logo 4 HEPARIN SODIUM 5 INJECTION, USP 6 Rx only 7 8 DERIVED FROM PORCINE INTESTINAL MUCOSA. 9 Available as: Preservative Free or Contains Benzyl Alcohol or Parabens 10 DESCRIPTION: 11 Heparin is a heterogeneous group of straight-chain anionic mucopolysaccharides, called 12 glycosaminoglycans, having anticoagulant properties. Although others may be present, the 13 main sugars occurring in heparin are: (1) α-L-iduronic acid 2-sulfate, (2) 2-deoxy-2­ 14 sulfamino-α-D-glucose 6-sulfate, (3) ß-D-glucuronic acid, (4) 2-acetamido-2-deoxy-α-D­ 15 glucose and (5) α-L-iduronic acid. These sugars are present in decreasing amounts, usually 16 in the order (2)> (1)> (4)> (3)> (5), and are joined by glycosidic linkages, forming polymers 17 of varying sizes. Heparin is strongly acidic because of its content of covalently linked sulfate 18 and carboxylic acid groups. In heparin sodium, the acidic protons of the sulfate units are 19 partially replaced by sodium ions. 20 Heparin Sodium Injection, USP is a sterile solution of heparin sodium derived from 21 porcine intestinal mucosa, standardized for anticoagulant activity, in water for injection. It is 22 to be administered by intravenous or deep subcutaneous routes. The potency is determined 23 by a biological assay using a USP reference standard based on units of heparin activity per 24 milligram. 1 This label may not be the latest approved by FDA.

Heparin acts at multiple sites in the normal coagulation system. 16 Small amounts of heparin in combination with antithrombin III (heparin cofactor) can inhibit 17 thrombosis by inactivating activated Factor X and inhibiting the conversion of prothrombin 18 to thrombin. Once active thrombosis has developed, larger amounts of heparin can inhibit 19 further coagulation by inactivating thrombin and preventing the conversion of fibrinogen to 20 fibrin. Heparin also prevents the formation of a stable fibrin clot by inhibiting the activation 21 of the fibrin stabilizing factor. 22 Bleeding time is usually unaffected by heparin. Clotting time is prolonged by full 23 therapeutic doses of heparin; in most cases, it is not measurably affected by low doses of 3 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda 1 heparin. 2 Patients over 60 years of age, following similar doses of heparin, may have higher 3 plasma levels of heparin and longer activated partial thromboplastin times (APTTs) 4 compared with patients under 60 years of age. 5 Peak plasma levels of heparin are achieved two to four hours following subcutaneous 6 administration, although there are considerable individual variations. Loglinear plots of 7 heparin plasma concentrations with time, for a wide range of dose levels, are linear, which 8 suggests the absence of zero order processes. Liver and the reticuloendothelial system are 9 the sites of biotransformation. The biphasic elimination curve, a rapidly declining alpha 10 phase (t1⁄2 = 10 minutes) and after the age of 40 a slower beta phase, indicates uptake in 11 organs. The absence of a relationship between anticoagulant half-life and concentration half­ 12 life may reflect factors such as protein binding of heparin. 13 Heparin does not have fibrinolytic activity; therefore, it will not lyse existing clots. 14 INDICATIONS AND USAGE: 15 Heparin Sodium Injection is indicated for: 16 Anticoagulant therapy in prophylaxis and treatment of venous thrombosis and its 17 extension; 18 Low-dose regimen for prevention of postoperative deep venous thrombosis and 19 pulmonary embolism in patients undergoing major abdominothoracic surgery or who, for 20 other reasons, are at risk of developing thromboembolic disease (see DOSAGE AND 21 ADMINISTRATION); 22 Prophylaxis and treatment of pulmonary embolism; 23 Atrial fibrillation with embolization; 4 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda 1 Diagnosis and treatment of acute and chronic consumptive coagulopathies 2 (disseminated intravascular coagulation); 3 Prevention of clotting in arterial and cardiac surgery; 4 Prophylaxis and treatment of peripheral arterial embolism. 5 Heparin may also be employed as an anticoagulant in blood transfusions, 6 extracorporeal circulation, and dialysis procedures and in blood samples for laboratory 7 purposes. 8 CONTRAINDICATIONS: 9 Heparin sodium should NOT be used in patients with the following conditions: 10 Severe thrombocytopenia; 11 When suitable blood coagulation tests, e.g., the whole blood clotting time, partial 12 thromboplastin time, etc., cannot be performed at appropriate intervals (this contraindication 13 refers to full-dose heparin; there is usually no need to monitor coagulation parameters in 14 patients receiving low-dose heparin); 15 An uncontrollable active bleeding state (see WARNINGS), except when this is due 16 to disseminated intravascular coagulation. 17 Pregnancy, Nursing Mothers, and Pediatric Use 18 Do not administer Heparin Sodium Injection, USP (porcine), preserved with benzyl alcohol 19 to neonates, infants, pregnant women, or nursing mothers (see PRECAUTIONS, 20 Pregnancy, Nursing Mothers, and Pediatric Use). Benzyl alcohol has been associated with 21 serious adverse events and death, particularly in pediatric patients. Heparin Sodium 22 Injection, USP (porcine), preservative free, when indicated, should be used in these 23 populations. 5 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda 1 WARNINGS: 2 Heparin is not intended for intramuscular use. 3 Fatal Medication Errors 4 Do not use Heparin Sodium Injection as a “catheter lock flush” product. Heparin Sodium 5 Injection is supplied in vials containing various strengths of heparin, including vials that 6 contain a highly concentrated solution of 10,000 units in 1 mL. Fatal hemorrhages have 7 occurred in pediatric patients due to medication errors in which 1 mL Heparin Sodium 8 Injection vials were confused with 1 mL “catheter lock flush” vials. Carefully examine all 9 Heparin Sodium Injection vials to confirm the correct vial choice prior to administration of 10 the drug. 11 Hypersensitivity 12 Patients with documented hypersensitivity to heparin should be given the drug only in clearly 13 life-threatening situations (see ADVERSE REACTIONS, Hypersensitivity). 14 Hemorrhage 15 Hemorrhage can occur at virtually any site in patients receiving heparin. An unexplained fall 16 in hematocrit, fall in blood pressure or any other unexplained symptom should lead to serious 17 consideration of a hemorrhagic event. 18 Heparin sodium should be used with extreme caution in disease states in which there 19 is increased danger of hemorrhage. Some of the conditions in which increased danger of 20 hemorrhage exists are: 21 22 Cardiovascular—Subacute bacterial endocarditis, severe hypertension. 23 24 Surgical—During and immediately following (a) spinal tap or spinal anesthesia or (b) major 6 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda 5 10 15 20 25 7 1 surgery, especially involving the brain, spinal cord, or eye. 2 3 Hematologic—Conditions associated with increased bleeding tendencies, such as 4 hemophilia, thrombocytopenia and some vascular purpuras. 6 Gastrointestinal—Ulcerative lesions and continuous tube drainage of the stomach or small 7 intestine. 8 9 Other—Menstruation, liver disease with impaired hemostasis. Coagulation Testing 11 When heparin sodium is administered in therapeutic amounts, its dosage should be regulated 12 by frequent blood coagulation tests. If the coagulation test is unduly prolonged or if 13 hemorrhage occurs, heparin sodium should be promptly discontinued (see 14 OVERDOSAGE). Thrombocytopenia 16 Thrombocytopenia has been reported to occur in patients receiving heparin with a reported 17 incidence of up to 30%. Platelet counts should be obtained at baseline and periodically 18 during heparin administration. Mild thrombocytopenia (count greater than 100,000/mm3) 19 may remain stable or reverse even if heparin is continued. However, thrombocytopenia of any degree should be monitored closely. If the count falls below 100,000/mm3 or if recurrent 21 thrombosis develops (see Heparin-induced Thrombocytopenia and Heparin-induced 22 Thrombocytopenia and Thrombosis), the heparin product should be discontinued, and, if 23 necessary, an alternative anticoagulant administered. 24 Heparin-induced Thrombocytopenia (HIT) and Heparin-induced Thrombocytopenia and Thrombosis (HITT) This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda 1 Heparin-induced Thrombocytopenia (HIT) is a serious antibody-mediated reaction 2 resulting from irreversible aggregation of platelets. HIT may progress to the 3 development of venous and arterial thromboses, a condition referred to as Heparin- 4 induced Thrombocytopenia and Thrombosis (HITT). Thrombotic events may also be 5 the initial presentation for HITT. These serious thromboembolic events include deep 6 vein thrombosis, pulmonary embolism, cerebral vein thrombosis, limb ischemia, stroke, 7 myocardial infarction, mesenteric thrombosis, renal arterial thrombosis, skin necrosis, 8 gangrene of the extremities that may lead to amputation, and possibly death. 9 Thrombocytopenia of any degree should be monitored closely. If the platelet count falls 10 below 100,000/mm 3 or if recurrent thrombosis develops, the heparin product should be 11 promptly discontinued and alternative anticoagulants considered, if patients require 12 continued anticoagulation. 13 Delayed Onset of HIT and HITT 14 Heparin-induced Thrombocytopenia and Heparin-induced Thrombocytopenia and 15 Thrombosis can occur up to several weeks after the discontinuation of heparin therapy. 16 Patients presenting with thrombocytopenia or thrombosis after discontinuation of heparin 17 should be evaluated for HIT and HITT. 18 PRECAUTIONS: 19 General 20 Thrombocytopenia, Heparin-induced Thrombocytopenia (HIT) and Heparin-induced 21 Thrombocytopenia and Thrombosis (HITT) 22 See WARNINGS. 23 Heparin Resistance—Increased resistance to heparin is frequently encountered in fever, 8 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda 5 10 15 20 25 9 1 thrombosis, thrombophlebitis, infections with thrombosing tendencies, myocardial infarction, 2 cancer and in postsurgical patients. 3 4 Increased Risk to Older Patients, Especially Women—A higher incidence of bleeding has been reported in patients, particularly women, over 60 years of age. 6 Laboratory Tests 7 Periodic platelet counts, hematocrits, and tests for occult blood in stool are recommended 8 during the entire course of heparin therapy, regardless of the route of administration (see 9 DOSAGE AND ADMINISTRATION). Drug Interactions 11 Oral Anticoagulants—Heparin sodium may prolong the one-stage prothrombin time. 12 Therefore, when heparin sodium is given with dicumarol or warfarin sodium, a period of at 13 least five hours after the last intravenous dose or 24 hours after the last subcutaneous dose 14 should elapse before blood is drawn, if a valid prothrombin time is to be obtained. 16 Platelet Inhibitors—Drugs such as acetylsalicylic acid, dextran, phenylbutazone, ibuprofen, 17 indomethacin, dipyridamole, hydroxychloroquine and others that interfere with platelet- 18 aggregation reactions (the main hemostatic defense of heparinized patients) may induce 19 bleeding and should be used with caution in patients receiving heparin sodium. 21 Other Interactions—Digitalis, tetracyclines, nicotine or antihistamines may partially 22 counteract the anticoagulant action of heparin sodium. Intravenous nitroglycerin 23 administered to heparinized patients may result in a decrease of the partial thromboplastin 24 time with subsequent rebound effect upon discontinuation of nitroglycerin. Careful monitoring of partial thromboplastin time and adjustment of heparin dosage are 26 recommended during coadministration of heparin and intravenous nitroglycerin. This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda 1 Drug/Laboratory Tests Interactions 2 Hyperaminotransferasemia—Significant elevations of aminotransferase (SGOT [S-AST] and 3 SGPT [S-ALT]) levels have occurred in a high percentage of patients (and healthy subjects) 4 who have received heparin. Since aminotransferase determinations are important in the 5 differential diagnosis of myocardial infarction, liver disease and pulmonary emboli, increases 6 that might be caused by drugs (like heparin) should be interpreted with caution. 7 Carcinogenesis, Mutagenesis, Impairment of Fertility 8 No long-term studies in animals have been performed to evaluate carcinogenic potential of 9 heparin. Also, no reproduction studies in animals have been performed concerning 10 mutagenesis or impairment of fertility. 11 Pregnancy 12 Do not administer Heparin Sodium Injection, USP (porcine), preserved with benzyl alcohol, 13 to pregnant women (see CONTRAINDICATIONS, Pregnancy, Nursing Mothers, and 14 Pediatric Use and PRECAUTIONS, Pediatric Use). Heparin Sodium Injection, USP 15 (porcine), preservative free, when indicated, should be administered to pregnant women. 16 17 Teratogenic Effects: Pregnancy Category C— 18 Animal reproduction studies have not been conducted with heparin sodium. It is also not 19 known whether heparin sodium can cause fetal harm when administered to a pregnant 20 woman or can affect reproduction capacity. Heparin sodium should be given to a pregnant 21 woman only if clearly needed. 22 23 Nonteratogenic Effects—Heparin does not cross the placental barrier. 24 10 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 Nursing Mothers Do not administer Heparin Sodium Injection, USP (porcine), preserved with benzyl alcohol, to nursing mothers (see CONTRAINDICATIONS, Pregnancy, Nursing Mothers, and Pediatric Use and PRECAUTIONS, Pediatric Use). Heparin Sodium Injection, USP (porcine), preservative free, when indicated, should be administered to nursing mothers. Heparin is not excreted in human milk. Pediatric Use See DOSAGE AND ADMINISTRATION, Pediatric Use. Do not administer Heparin Sodium Injection, USP (porcine), preserved with benzyl alcohol, to neonates and infants (see CONTRAINDICATIONS, Pregnancy, Nursing Mothers, and Pediatric Use). Heparin Sodium Injection, USP (porcine), preservative free, when indicated, should be administered to neonates and infants. Benzyl alcohol has been associated with serious adverse events and death, particularly in pediatric patients. The “gasping syndrome,” (characterized by central nervous system depression, metabolic acidosis, gasping respirations, and high levels of benzyl alcohol and its metabolites found in the blood and urine) has been associated with benzyl alcohol dosages >99mg/kg/day in neonates and low-birthweight neonates. Additional symptoms may include gradual neurological deterioration, seizures, intracranial hemorrhage, hematologic abnormalities, skin breakdown, hepatic and renal failure, hypotension, bradycardia, and cardiovascular collapse. Although normal therapeutic doses of this product deliver amounts of benzyl alcohol that are substantially lower than those reported in association with the “gasping syndrome”, the minimum amount of benzyl alcohol at which toxicity may occur is not known. Premature and low-birthweight infants, as well as patients receiving high dosages, may be more likely 11 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda 12 1 to develop toxicity. Practitioners administering this and other medications containing benzyl 2 alcohol should consider the combined daily metabolic load of benzyl alcohol from all 3 sources. 4 Geriatric Use 5 A higher incidence of bleeding has been reported in patients over 60 years of age, especially 6 women (see PRECAUTIONS, General). Clinical studies indicate that lower doses of 7 heparin may be indicated in these patients (see CLINICAL PHARMACOLOGY and 8 DOSAGE AND ADMINISTRATION). 9 ADVERSE REACTIONS: 10 Hemorrhage 11 Hemorrhage is the chief complication that may result from heparin therapy (see 12 WARNINGS). An overly prolonged clotting time or minor bleeding during therapy can 13 usually be controlled by withdrawing the drug (see OVERDOSAGE). It should be 14 appreciated that gastrointestinal or urinary tract bleeding during anticoagulant 15 therapy may indicate the presence of an underlying occult lesion. Bleeding can occur at 16 any site but certain specific hemorrhagic complications may be difficult to detect: 17 (a) Adrenal hemorrhage, with resultant acute adrenal insufficiency, has occurred during 18 anticoagulant therapy. Therefore, such treatment should be discontinued in patients who 19 develop signs and symptoms of acute adrenal hemorrhage and insufficiency. Initiation of 20 corrective therapy should not depend on laboratory confirmation of the diagnosis, since any 21 delay in an acute situation may result in the patient’s death. 22 (b) Ovarian (corpus luteum) hemorrhage developed in a number of women of reproductive 23 age receiving short- or long-term anticoagulant therapy. This complication, if unrecognized, This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 may be fatal. (c) Retroperitoneal hemorrhage. Thrombocytopenia, Heparin-induced Thrombocytopenia (HIT) and Heparin-induced Thrombocytopenia and Thrombosis (HITT) and Delayed Onset of HIT and HITT See WARNINGS. Local Irritation Local irritation, erythema, mild pain, hematoma or ulceration may follow deep subcutaneous (intrafat) injection of heparin sodium. These complications are much more common after intramuscular use, and such use is not recommended. Hypersensitivity Generalized hypersensitivity reactions have been reported, with chills, fever and urticaria as the most usual manifestations, and asthma, rhinitis, lacrimation, headache, nausea and vomiting, and anaphylactoid reactions, including shock, occurring more rarely. Itching and burning, especially on the plantar side of the feet, may occur (see WARNINGS and PRECAUTIONS). Certain episodes of painful, ischemic and cyanosed limbs have in the past been attributed to allergic vasospastic reactions. Whether these are in fact identical to the thrombocytopenia-associated complications, remains to be determined. Miscellaneous Osteoporosis following long-term administration of high doses of heparin, cutaneous necrosis after systemic administration, suppression of aldosterone synthesis, delayed transient alopecia, priapism, and rebound hyperlipemia on discontinuation of heparin sodium have also been reported. 13 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda 1 Significant elevations of aminotransferase (SGOT [S-AST] and SGPT [S-ALT]) 2 levels have occurred in a high percentage of patients (and healthy subjects) who have 3 received heparin. 4 OVERDOSAGE: 5 Symptoms 6 Bleeding is the chief sign of heparin overdosage. Nosebleeds, blood in urine or tarry stools 7 may be noted as the first sign of bleeding. Easy bruising or petechial formations may 8 precede frank bleeding. 9 Treatment 10 Neutralization of Heparin Effect—When clinical circumstances (bleeding) require reversal of 11 heparinization, protamine sulfate (1% solution) by slow infusion will neutralize heparin 12 sodium. No more than 50 mg should be administered, very slowly, in any 10 minute 13 period. Each mg of protamine sulfate neutralizes approximately 100 USP heparin units. The 14 amount of protamine required decreases over time as heparin is metabolized. Although the 15 metabolism of heparin is complex, it may, for the purpose of choosing a protamine dose, be 16 assumed to have a half-life of about 1/2 hour after intravenous injection. 17 Administration of protamine sulfate can cause severe hypotensive and anaphylactoid 18 reactions. Because fatal reactions often resembling anaphylaxis have been reported, the drug 19 should be given only when resuscitation techniques and treatment of anaphylactoid shock are 20 readily available. 21 For additional information consult the labeling of Protamine Sulfate Injection, USP 22 products. 23 14 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 DOSAGE AND ADMINISTRATION: Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration, whenever solution and container permit. Slight discoloration does not alter potency. Confirm the choice of the correct Heparin Sodium Injection vial prior to administration of the drug to a patient (see WARNINGS, Fatal Medication Errors). The 1 mL vial must not be confused with a “catheter lock flush” vial or other 1 mL vial of inappropriate strength. Confirm that you have selected the correct medication and strength prior to administration of the drug. When heparin is added to an infusion solution for continuous intravenous administration, the container should be inverted at least six times to ensure adequate mixing and prevent pooling of the heparin in the solution. Heparin sodium is not effective by oral administration and should be given by intermittent intravenous injection, intravenous infusion, or deep subcutaneous (intrafat, i.e., above the iliac crest or abdominal fat layer) injection. The intramuscular route of administration should be avoided because of the frequent occurrence of hematoma at the injection site. The dosage of heparin sodium should be adjusted according to the patient’s coagulation test results. When heparin is given by continuous intravenous infusion, the coagulation time should be determined approximately every four hours in the early stages of treatment. When the drug is administered intermittently by intravenous injection, coagulation tests should be performed before each injection during the early stages of treatment and at appropriate intervals thereafter. Dosage is considered adequate when the 15 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 activated partial thromboplastin time (APTT) is 1.5 to 2 times normal or when the whole blood clotting time is elevated approximately 2.5 to 3 times the control value. After deep subcutaneous (intrafat) injections, tests for adequacy of dosage are best performed on samples drawn four to six hours after the injection. Periodic platelet counts, hematocrits and tests for occult blood in stool are recommended during the entire course of heparin therapy, regardless of the route of administration. Converting to Oral Anticoagulant When an oral anticoagulant of the coumarin or similar type is to be begun in patients already receiving heparin sodium, baseline and subsequent tests of prothrombin activity must be determined at a time when heparin activity is too low to affect the prothrombin time. This is about five hours after the last IV bolus and 24 hours after the last subcutaneous dose. If continuous IV heparin infusion is used, prothrombin time can usually be measured at any time. In converting from heparin to an oral anticoagulant, the dose of the oral anticoagulant should be the usual initial amount and thereafter prothrombin time should be determined at the usual intervals. To ensure continuous anticoagulation, it is advisable to continue full heparin therapy for several days after the prothrombin time has reached the therapeutic range. Heparin therapy may then be discontinued without tapering. Therapeutic Anticoagulant Effect With Full-Dose Heparin Although dosage must be adjusted for the individual patient according to the results of suitable laboratory tests, the following dosage schedules may be used as guidelines: 16 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda 1 METHOD OF RECOMMENDED ADMINISTRATION FREQUENCY DOSE (based on 150 lb [68 kg] patient) Deep Subcutaneous (Intrafat) Injection A different site should be used for each injection to prevent the development of massive hematoma Initial Dose Every 8 hours or Every 12 hours 5,000 units by IV injection, followed by 10,000 to 20,000 units of a concentrated solution, subcutaneously 8,000 to 10,000 units of a concentrated solution 15,000 to 20,000 units of a concentrated solution Intermittent Intravenous Injection Initial Dose Every 4 to 6 hours Intravenous Infusion Initial Dose Continuous 10,000 units, either undiluted or in 50 to 100 mL of 0.9% Sodium Chloride Injection, USP 5,000 to 10,000 units, either undiluted or in 50 to 100 mL of 0.9% Sodium Chloride Injection, USP 5,000 units by IV injection 20,000 to 40,000 units/24 hours in 1,000 mL of 0.9% Sodium Chloride Injection, USP (or in any compatible solution) for infusion 17 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 Pediatric Use Do not administer Heparin Sodium Injection, USP (porcine), preserved with benzyl alcohol, to neonates and infants (see CONTRAINDICATIONS, Pregnancy, Nursing Mothers, and Pediatric Use and PRECAUTIONS, Pediatric Use). When indicated, Heparin Sodium Injection, USP (porcine), preservative free should be used in neonates and infants. Follow recommendations of appropriate pediatric reference texts. In general, the following dosage schedule may be used as a guideline: Initial Dose: 50 units/kg (IV, infusion) Maintenance Dose: 100 units/kg (IV, infusion) every four hours, or 20,000 units/m2/24 hours continuously Geriatric Use Patients over 60 years of age may require lower doses of heparin. Surgery of the Heart and Blood Vessels Patients undergoing total body perfusion for open-heart surgery should receive an initial dose of not less than 150 units of heparin sodium per kilogram of body weight. Frequently, a dose of 300 units of heparin sodium per kilogram of body weight is used for procedures estimated to last less than 60 minutes, or 400 units per kilogram for those estimated to last longer than 60 minutes. Low-Dose Prophylaxis of Postoperative Thromboembolism A number of well-controlled clinical trials have demonstrated that low-dose heparin prophylaxis, given just prior to and after surgery, will reduce the incidence of postoperative deep vein thrombosis in the legs (as measured by the I-125 fibrinogen technique and venography) and of clinical pulmonary embolism. The most widely used dosage has been 18 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 5,000 units 2 hours before surgery and 5,000 units every 8 to 12 hours thereafter for seven days or until the patient is fully ambulatory, whichever is longer. The heparin is given by deep subcutaneous injection in the arm or abdomen with a fine needle (25 to 26 gauge) to minimize tissue trauma. A concentrated solution of heparin sodium is recommended. Such prophylaxis should be reserved for patients over the age of 40 who are undergoing major surgery. Patients with bleeding disorders and those having neurosurgery, spinal anesthesia, eye surgery or potentially sanguineous operations should be excluded, as well as patients receiving oral anticoagulants or platelet-active drugs (see WARNINGS). The value of such prophylaxis in hip surgery has not been established. The possibility of increased bleeding during surgery or postoperatively should be borne in mind. If such bleeding occurs, discontinuance of heparin and neutralization with protamine sulfate are advisable. If clinical evidence of thromboembolism develops despite low-dose prophylaxis, full therapeutic doses of anticoagulants should be given unless contraindicated. All patients should be screened prior to heparinization to rule out bleeding disorders, and monitoring should be performed with appropriate coagulation tests just prior to surgery. Coagulation test values should be normal or only slightly elevated. There is usually no need for daily monitoring of the effect of low-dose heparin in patients with normal coagulation parameters. Extracorporeal Dialysis Follow equipment manufacturers’ operating directions carefully. Blood Transfusion Addition of 400 to 600 USP units per 100 mL of whole blood is usually employed to prevent coagulation. Usually, 7,500 USP units of heparin sodium are added to 100 mL of 0.9% Sodium Chloride Injection, USP (or 75,000 USP units/1,000 mL of 0.9% Sodium Chloride 19 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda 1 Injection, USP) and mixed; from this sterile solution, 6 to 8 mL are added per 100 mL of 2 whole blood. 3 Laboratory Samples 4 Addition of 70 to 150 units of heparin sodium per 10 to 20 mL sample of whole blood is 5 usually employed to prevent coagulation of the sample. Leukocyte counts should be 6 performed on heparinized blood within two hours after addition of the heparin. Heparinized 7 blood should not be used for isoagglutinin, complement, or erythrocyte fragility tests or 8 platelet counts. 9 HOW SUPPLIED: 10 Heparin Sodium Injection, USP (porcine), preservative free, is available as follows: Product NDC No. No. 27602 63323-276-02 1,000 USP Heparin Units/mL, 2 mL fill in a 2 mL single dose, flip-top vial, in packages of 25. 11 12 Preservative Free 13 Discard Unused Portion. 14 Do not use if solution is discolored or contains a precipitate. 15 16 Heparin Sodium Injection, USP (porcine) contains benzyl alcohol and is available as 17 follows: Product NDC No. No. 4710 63323-047-10 5,000 USP Heparin Units/mL, 10 mL fill in a 10 mL multiple dose, flip-top vial, in packages of 25. 20 This label may not be the latest approved by FDA.

Isoflurane has a mildly pungent, musty, ethereal odor. Samples stored in indirect sunlight in clear, colorless glass for five years, as well as samples directly exposed for 30 hours to a 2 amp, 115 volt, 60 cycle long wave U.V. light were unchanged in composition as determined by gas chromatography. Isoflurane in one normal sodium methoxide-methanol solution, a strong base, for over six months consumed essentially no alkali, indicative of strong base stability. Isoflurane does not decompose in the presence of soda lime (at normal operating temperatures), and does not attack aluminum, tin, brass, iron or copper. CLINICAL PHARMACOLOGY FORANE (isoflurane, USP) is an inhalation anesthetic. The MAC (minimum alveolar concentration) in man is as follows: Age 100% Oxygen 70% N20 26±4 1.28 0.56 44±7 1.15 0.50 64±5 1.05 0.37 2 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda Forane ® (isoflurane, USP) Proposed Package Insert Induction of and recovery from isoflurane anesthesia are rapid. Isoflurane has a mild pungency, which limits the rate of induction, although excessive salivation or tracheobronchial secretions do not appear to be stimulated. Pharyngeal and laryngeal reflexes are readily obtunded. The level of anesthesia may be changed rapidly with isoflurane. Isoflurane is a profound respiratory depressant. RESPIRATION MUST BE MONITORED CLOSELY AND SUPPORTED WHEN NECESSARY. As anesthetic dose is increased, tidal volume decreases and respiratory rate is unchanged. This depression is partially reversed by surgical stimulation, even at deeper levels of anesthesia. Isoflurane evokes a sigh response reminiscent of that seen with diethyl ether and enflurane, although the frequency is less than with enflurane. Blood pressure decreases with induction of anesthesia but returns toward normal with surgical stimulation. Progressive increases in depth of anesthesia produce corresponding decreases in blood pressure. Nitrous oxide diminishes the inspiratory concentration of isoflurane required to reach a desired level of anesthesia and may reduce the arterial hypotension seen with isoflurane alone. Heart rhythm is remarkably stable. With controlled ventilation and normal PaCO2, cardiac output is maintained despite increasing depth of anesthesia, primarily through an increase in heart rate, which compensates for a reduction in stroke volume. The hypercapnia, which attends spontaneous ventilation during isoflurane anesthesia further increases heart rate and raises cardiac output above awake levels. Isoflurane does not sensitize the myocardium to exogenously administered epinephrine in the dog. Limited data indicate that subcutaneous injection of 0.25 mg of epinephrine (50 mL of 1:200,000 solution) does not produce an increase in ventricular arrhythmias in patients anesthetized with isoflurane. Muscle relaxation is often adequate for intra-abdominal operations at normal levels of anesthesia. Complete muscle paralysis can be attained with small doses of muscle relaxants. ALL COMMONLY USED MUSCLE RELAXANTS ARE MARKEDLY POTENTIATED WITH ISOFLURANE, THE EFFECT BEING MOST PROFOUND WITH THE NONDEPOLARIZING TYPE. Neostigmine reverses the effect of nondepolarizing muscle relaxants in the presence of isoflurane. All commonly used muscle relaxants are compatible with isoflurane. Isoflurane can produce coronary vasodilation at the arteriolar level in selected animal models 1,2; the drug is probably also a coronary dilator in humans. Isoflurane, like some other coronary arteriolar dilators, has been shown to divert blood from collateral dependent myocardium to normally perfused areas in an animal model (“coronary steal”) 3. Clinical studies to date evaluating myocardial ischemia, infarction and death as outcome 3 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda Forane ® (isoflurane, USP) Proposed Package Insert parameters have not established that the coronary arteriolar dilation property of isoflurane is associated with coronary steal or myocardial ischemia in patients with coronary artery disease 4,5,6,7. Pharmacokinetics Isoflurane undergoes minimal biotransformation in man. In the postanesthesia period, only 0.17% of the isoflurane taken up can be recovered as urinary metabolites. INDICATIONS AND USAGE FORANE (isoflurane, USP) may be used for induction and maintenance of general anesthesia. Adequate data have not been developed to establish its application in obstetrical anesthesia. CONTRAINDICATIONS Known sensitivity to FORANE (isoflurane, USP) or to other halogenated agents. Known or suspected genetic susceptibility to malignant hyperthermia. WARNINGS Perioperative Hyperkalemia Use of inhaled anesthetic agents has been associated with rare increases in serum potassium levels that have resulted in cardiac arrhythmias and death in pediatric patients during the postoperative period. Patients with latent as well as overt neuromuscular disease, particularly Duchenne muscular dystrophy, appear to be most vulnerable. Concomitant use of succinylcholine has been associated with most, but not all, of these cases. These patients also experienced significant elevations in serum creatinine kinase levels and, in some cases, changes in urine consistent with myoglobinuria. Despite the similarity in presentation to malignant hyperthermia, none of these patients exhibited signs or symptoms of muscle rigidity or hypermetabolic state. Early and aggressive intervention to treat the hyperkalemia and resistant arrhythmias is recommended, as is subsequent evaluation for latent neuromuscular disease. Malignant Hyperthermia In susceptible individuals, isoflurane anesthesia may trigger a skeletal muscle hypermetabolic state leading to high oxygen demand and the clinical syndrome known as malignant hyperthermia. The syndrome includes nonspecific features such as muscle rigidity, tachycardia, tachypnea, cyanosis, arrhythmias, and unstable blood pressure. (It 4 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda Forane ® (isoflurane, USP) Proposed Package Insert should also be noted that many of these nonspecific signs may appear with light anesthesia, acute hypoxia, etc.) An increase in overall metabolism may be reflected in an elevated temperature, (which may rise rapidly early or late in the case, but usually is not the first sign of augmented metabolism) and an increased usage of the CO absorption 2 system (hot canister). PaO and pH may decrease, and hyperkalemia and a base deficit 2 may appear. Treatment includes discontinuance of triggering agents (e.g., isoflurane), administration of intravenous dantrolene sodium, and application of supportive therapy. Such therapy includes vigorous efforts to restore body temperature to normal, respiratory and circulatory support as indicated, and management of electrolyte-fluid-acid-base derangements. (Consult prescribing information for dantrolene sodium intravenous for additional information on patient management). Renal failure may appear later, and urine flow should be sustained if possible. Since levels of anesthesia may be altered easily and rapidly, only vaporizers producing predictable concentrations should be used. Hypotension and respiratory depression increase as anesthesia is deepened. Increased blood loss comparable to that seen with halothane has been observed in patients undergoing abortions. FORANE (isoflurane, USP) markedly increases cerebral blood flow at deeper levels of anesthesia. There may be a transient rise in cerebral spinal fluid pressure, which is fully reversible with hyperventilation. PRECAUTIONS General As with any potent general anesthetic, FORANE (isoflurane, USP) should only be administered in an adequately equipped anesthetizing environment by those who are familiar with the pharmacology of the drug and qualified by training and experience to manage the anesthetized patient. Regardless of the anesthetics employed, maintenance of normal hemodynamics is important to the avoidance of myocardial ischemia in patients with coronary artery disease 4,5,6,7. FORANE (isoflurane, USP), like some other inhalational anesthetics, can react with desiccated carbon dioxide (CO2) absorbents to produce carbon monoxide, which may result in elevated levels of carboxyhemoglobin in some patients. Case reports suggest that 5 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda Forane ® (isoflurane, USP) Proposed Package Insert barium hydroxide lime and soda lime become desiccated when fresh gases are passed through the CO2 absorber canister at high flow rates over many hours or days. When a clinician suspects that CO2 absorbent may be desiccated, it should be replaced before the administration of FORANE (isoflurane, USP). As with other halogenated anesthetic agents, FORANE (isoflurane, USP) may cause sensitivity hepatitis in patients who have been sensitized by previous exposure to halogenated anesthetics (see CONTRAINDICATIONS). Information for Patients Isoflurane, as well as other general anesthetics, may cause a slight decrease in intellectual function for 2 or 3 days following anesthesia. As with other anesthetics, small changes in moods and symptoms may persist for up to 6 days after administration. Laboratory Tests Transient increases in BSP retention, blood glucose and serum creatinine with decrease in BUN, serum cholesterol and alkaline phosphatase have been observed. Drug Interactions Isoflurane potentiates the muscle relaxant effect of all muscle relaxants, most notably nondepolarizing muscle relaxants, and MAC (minimum alveolar concentration) is reduced by concomitant administration of N2O. See CLINICAL PHARMACOLOGY. Carcinogenesis, Mutagenesis, Impairment of Fertility Swiss ICR mice were given isoflurane to determine whether such exposure might induce neoplasia. Isoflurane was given at ½, ⅛ and 1/32 MAC for four in-utero exposures and for 24 exposures to the pups during the first nine weeks of life. The mice were killed at 15 months of age. The incidence of tumors in these mice was the same as in untreated control mice, which were given the same background gases, but not the anesthetic. Pregnancy Pregnancy Category C Isoflurane has been shown to have a possible anesthetic-related fetotoxic effect in mice when given in doses 6 times the human dose. There are no adequate and well-controlled studies in pregnant women. Isoflurane should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus. 6 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda Forane ® (isoflurane, USP) Proposed Package Insert Nursing Mothers It is not known whether this drug is excreted in human milk. Because many drugs are excreted in human milk, caution should be exercised when isoflurane is administered to a nursing woman. ADVERSE REACTIONS Adverse reactions encountered in the administration of FORANE (isoflurane, USP) are in general dose dependent extensions of pharmacophysiologic effects and include respiratory depression, hypotension and arrhythmias. Shivering, nausea, vomiting and ileus have been observed in the postoperative period. As with all other general anesthetics, transient elevations in white blood count have been observed even in the absence of surgical stress. See WARNINGS for information regarding malignant hyperthermia and elevated carboxyhemoglobin levels. During marketing, there have been rare reports of mild, moderate and severe (some fatal) postoperative hepatic dysfunction and hepatitis. FORANE (isoflurane, USP) has also been associated with perioperative hyperkalemia (see WARNINGS). Post-Marketing Events: The following adverse events have been identified during post-approval use of FORANE (isoflurane, USP). Due to the spontaneous nature of these reports, the actual incidence and relationship of FORANE (isoflurane, USP) to these events cannot be established with certainty. Cardiac Disorders: Cardiac arrest Hepatobiliary Disorders: Hepatic necrosis, Hepatic failure . OVERDOSAGE In the event of overdosage, or what may appear to be overdosage, the following action should be taken: Stop drug administration, establish a clear airway, and initiate assisted or controlled ventilation with pure oxygen. 7 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda Forane ® (isoflurane, USP) Proposed Package Insert DOSAGE AND ADMINISTRATION Premedication Premedication should be selected according to the need of the individual patient, taking into account that secretions are weakly stimulated by FORANE (isoflurane, USP), and the heart rate tends to be increased. The use of anticholinergic drugs is a matter of choice. Inspired Concentration The concentration of isoflurane being delivered from a vaporizer during anesthesia should be known. This may be accomplished by using: a. Vaporizers calibrated specifically for isoflurane; b. Vaporizers from which delivered flows can be calculated, such as vaporizers delivering a saturated vapor, which is then diluted. The delivered concentration from such a vaporizer may be calculated using the formula: % isoflurane = 100 P F v v FT (PA – PV) = Where: : P Pressure of atmosphere A = P Vapor pressure of isoflurane V = FV Flow of gas through vaporizer (mL/min) = FT Total gas flow (mL/min) Isoflurane contains no stabilizer. Nothing in the agent alters calibration or operation of these vaporizers. Induction Induction with isoflurane in oxygen or in combination with oxygen-nitrous oxide mixtures may produce coughing, breath holding, or laryngospasm. These difficulties may be avoided by the use of a hypnotic dose of an ultra-short-acting barbiturate. Inspired concentrations of 1.5 to 3.0% isoflurane usually produce surgical anesthesia in 7 to 10 minutes. Maintenance 8 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda Forane ® (isoflurane, USP) Proposed Package Insert Surgical levels of anesthesia may be sustained with a 1.0 to 2.5% concentration when nitrous oxide is used concomitantly. An additional 0.5 to 1.0% may be required when isoflurane is given using oxygen alone. If added relaxation is required, supplemental doses of muscle relaxants may be used. The level of blood pressure during maintenance is an inverse function of isoflurane concentration in the absence of other complicating problems. Excessive decreases may be due to depth of anesthesia and in such instances may be corrected by lightening anesthesia. HOW SUPPLIED FORANE (isoflurane, USP) is packaged in 100 mL and 250 mL amber-colored bottles. 100 mL NDC 10019-360-40 250 mL NDC 10019-360-60 FORANE (isoflurane, USP) is also supplied in the following aluminum bottles. 250 mL NDC 10019-360-64 Safety and Handling Occupational Caution There is no specific work exposure limit established for FORANE (isoflurane, USP). However, the National Institute for Occupational Safety and Health Administration (NIOSH) recommends that no worker should be exposed at ceiling concentrations greater than 2 ppm of any halogenated anesthetic agent over a sampling period not to exceed one hour. The predicted effects of acute overexposure by inhalation of FORANE (isoflurane, USP) include headache, dizziness or (in extreme cases) unconsciousness. There are no documented adverse effects of chronic exposure to halogenated anesthetic vapors (Waste Anesthetic Gases or WAGs) in the workplace. Although results of some epidemiological studies suggest a link between exposure to halogenated anesthetics and increased health problems (particularly spontaneous abortion), the relationship is not conclusive. Since exposure to WAGs is one possible factor in the findings for these studies, operating room personnel, and pregnant women in particular, should minimize exposure. Precautions 9 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda Forane ® (isoflurane, USP) Proposed Package Insert include adequate general ventilation in the operating room, the use of a well-designed and well-maintained scavenging system, work practices to minimize leaks and spills while the anesthetic agent is in use, and routine equipment maintenance to minimize leaks. Storage Store at room temperature 15°-30°C (59°-86°F). Isoflurane contains no additives and has been demonstrated to be stable at room temperature for periods in excess of five years.

For current labeling information, please visit https://www.fda.gov/drugsatfda FULL PRESCRIBING INFORMATION WARNING: RISK OF SERIOUS CARDIOVASCULAR AND GASTROINTESTINAL EVENTS Cardiovascular Thrombic Events ● Non-Steroidal Anti-Inflammatory drugs (NSAIDs) cause an increased risk of serious cardiovascular thrombotic events, including myocardial infarction and stroke, which can be fatal. This risk may occur early in treatment and may increase with duration of use. [see Warnings and Precautions (5.1)]. ● NALFON® is contraindicated in the setting of coronary artery bypass graft (CABG) surgery [see Contraindications (4) and Warnings and precautions (5.1)]. Gastrointestinal Bleeding, Ulceration, and Perforation ● NSAIDs cause an increased risk of serious gastrointestinal (GI) adverse events including bleeding, ulceration, and perforation of stomach or intestines, which can be fatal. These events can occur at any time during use and without warning symptoms. Elderly patients and patients with a prior history of peptic ulcer disease and/or GI bleeding are at greater risk for serious GI events [see Warnings and Precautions (5.2)]. 1. INDICATIONS AND USAGE NALFON is indicated for:  Relief of mild to moderate pain in adults  Relief of the signs and symptoms of rheumatoid arthrites  Relief of the signs and symptoms of osteoarthritis 2. DOSAGE AND ADMINISTRATION 2.1 General Dosing Instructions Carefully consider the potential benefits and risks of NALFON and other treatment options before deciding to use NALFON. Use the lowest effective dose for the shortest duration consistent with individual patient treatment goals Use lowest effective dosage for the shortest duration consistent with individual patient treatment goals [see Warnings and Precautions (5)]. Nalfon may be administered with meals or with milk. Although the total amount absorbed is not affected, peak blood levels are delayed and diminished. Patients with rheumatoid arthritis generally seem to require larger doses of Nalfon than do those with osteoarthritis. The smallest dose that yields acceptable control should be employed. Although improvement may be seen in a few days in many patients, an additional 2 to 3 weeks may be required to gauge the full benefits of therapy. 2.2 Analgesia For the treatment of mild to moderate pain , the recommended dosage is 200 mg given orally every 4 to 6 hours, as needed. 2.3 Rheumatoid Arthritis and Osteoarthritis For the relief of signs and symptoms of rheumatoid arthritis or osteoarthritis the recommended dose is 400 to 600 mg given orally, 3 or 4 times a day. The dose should be tailored to the needs of the patient and may be increased or decreased depending on the severity of the symptoms. Dosage adjustments may be made after initiation of drug therapy or during exacerbations of the disease. Total daily dosage should not exceed 3,200 mg. 3. DOSAGE FORMS AND STRENGTHS Nalfon® (fenoprofen calcium, USP) capsules: ● The 200 mg capsule is opaque yellow No. 97 cap and opaque white body, imprinted with "RX681" on the cap and body. ● The 400 mg capsule is opaque green cap and opaque blue body, imprinted with "NALFON 400 mg" on the cap and "EP 123" on the body. 4. CONTRAINDICATIONS NALFON is contraindicated in the following patients: ● Known hypersensitivity (e.g., anaphylactic reactions and serious skin reactions) to fenoprofen or any components of the drug product [see Warnings and Precautions (5.7, 5.9)] Reference ID: 3928124 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda ● History of asthma, urticaria, or other allergic-type reactions after taking aspirin or other NSAIDs. Severe, sometimes fatal, anaphylactic reactions to NSAIDs have been reported in such patients [see Warnings and Precautions (5.7, 5.8)] ● In the setting of coronary artery bypass graft (CABG) surgery [see Warnings and Precautions (5.1)] 5. WARNINGS AND PRECAUTIONS 5.1 Cardiovascular Thrombotic Events Clinical trials of several COX-2 selective and nonselective NSAIDs of up to three years duration have shown an increased risk of serious cardiovascular (CV) thrombotic events, including myocardial infarction (MI) and stroke, which can be fatal. Based on available data, it is unclear that the risk for CV thrombotic events is similar for all NSAIDs. The relative increase in serious CV thrombotic events over baseline conferred by NSAID use appears to be similar in those with and without known CV disease or risk factors for CV disease. However, patients with known CV disease or risk factors had a higher absolute incidence of excess serious CV thrombotic events, due to their increased baseline rate. Some observational studies found that this increased risk of serious CV thrombotic events began as early as the first weeks of treatment. The increase in CV thrombotic risk has been observed most consistently at higher doses. To minimize the potential risk for an adverse CV event in NSAID-treated patients, use the lowest effective dose for the shortest duration possible. Physicians and patients should remain alert for the development of such events, throughout the entire treatment course, even in the absence of previous CV symptoms. Patients should be informed about the symptoms of serious CV events and the steps to take if they occur. There is no consistent evidence that concurrent use of aspirin mitigates the increased risk of serious CV thrombotic events associated with NSAID use. The concurrent use of aspirin and an NSAID, such as fenoprofen, increases the risk of serious gastrointestinal (GI) events [see Warnings and Precautions (5.2)]. Status Post Coronary Artery Bypass Graft (CABG) Surgery Two large, controlled clinical trials of a COX-2 selective NSAID for the treatment of pain in the first 10–14 days following CABG surgery found an increased incidence of myocardial infarction and stroke. NSAIDs are contraindicated in the setting of CABG [see Contraindications (4)]. Post-MI Patients Observational studies conducted in the Danish National Registry have demonstrated that patients treated with NSAIDs in the post-MI period were at increased risk of reinfarction, CV-related death, and all-cause mortality beginning in the first week of treatment. In this same cohort, the incidence of death in the first year post-MI was 20 per 100 person years in NSAID-treated patients compared to 12 per 100 person years in non-NSAID exposed patients. Although the absolute rate of death declined somewhat after the first year post- MI, the increased relative risk of death in NSAID users persisted over at least the next four years of follow-up. Avoid the use of NALFON in patients with a recent MI unless the benefits are expected to outweigh the risk of recurrent CV thrombotic events. If NALFON is used in patients with a recent MI, monitor patients for signs of cardiac ischemia. 5.2 Gastrointestinal Bleeding, Ulceration, and Perforation NSAIDs, including NALFON, cause serious gastrointestinal (GI) adverse events including inflammation, bleeding, ulceration, and perforation of the esophagus, stomach, small intestine, or large intestine, which can be fatal. These serious adverse events can occur at any time, with or without warning symptoms, in patients treated with NSAIDs. Only one in five patients who develop a serious upper GI adverse event on NSAID therapy is symptomatic. Upper GI ulcers, gross bleeding, or perforation caused by NSAIDs occurred in approximately 1% of patients treated for 3-6 months, and in about 2%-4% of patients treated for one year. However, even short-term NSAID therapy is not without risk. Risk Factors for GI Bleeding, Ulceration, and Perforation Patients with a prior history of peptic ulcer disease and/or GI bleeding who used NSAIDs had a greater than 10-fold increased risk for developing a GI bleed compared to patients without these risk factors. Other factors that increase the risk of GI bleeding in patients treated with NSAIDs include longer duration of NSAID therapy; concomitant use of oral corticosteroids, aspirin, anticoagulants, or selective serotonin reuptake inhibitors (SSRIs); smoking; use of alcohol; older age; and poor general health status. Most postmarketing reports of fatal GI events occurred in elderly or debilitated patients. Additionally, patients with advanced liver disease and/or coagulopathy are at increased risk for GI bleeding. Strategies to Minimize the GI Risks in NSAID-treated Patients: ● Use the lowest effective dosage for the shortest possible duration. ● Avoid administration of more than one NSAID at a time. ● Avoid use in patients at higher risk unless benefits are expected to outweigh theincreased risk of bleeding. For such patients, as well as those with active GIbleeding, consider alternate therapies other than NSAIDs. ● Remain alert for signs and symptoms of GI ulceration and bleeding during NSAID therapy. Reference ID: 3928124 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda ● If a serious GI adverse event is suspected, promptly initiate evaluation and treatment, and discontinue NALFON until a serious GI adverse event is ruled out. ● In the setting of concomitant use of low-dose aspirin for cardiac prophylaxis, monitor patients more closely for evidence of GI bleeding [see Drug Interactions (7)]. 5.3 Hepatotoxicity Elevations of ALT or AST (three or more times the upper limit of normal [ULN]) have been reported in approximately 1% of NSAID- treated patients in clinical trials. In addition, rare, sometimes fatal, cases of severe hepatic injury, including fulminant hepatitis, liver necrosis, and hepatic failure have been reported. Elevations of ALT or AST (less than three times ULN) may occur in up to 15% of patients treated with NSAIDs including fenoprofen. Inform patients of the warning signs and symptoms of hepatotoxicity (e.g., nausea, fatigue, lethargy, diarrhea, pruritus, jaundice, right upper quadrant tenderness, and "flu-like" symptoms). If clinical signs and symptoms consistent with liver disease develop, or if systemic manifestations occur (e.g., eosinophilia, rash, etc.), discontinue NALFON immediately, and perform a clinical evaluation of the patient. 5.4 Hypertension NSAIDs, including NALFON, can lead to new onset of hypertension or worsening of preexisting hypertension, either of which may contribute to the increased incidence of CV events. Patients taking angiotensin converting enzyme (ACE) inhibitors, thiazide diuretics, or loop diuretics may have impaired response to these therapies when taking NSAIDs [see Drug Interactions (7)]. Monitor blood pressure (BP) during the initiation of NSAID treatment and throughout the course of therapy. 5.5 Heart Failure and Edema The Coxib and traditional NSAID Trialists’ Collaboration meta-analysis of randomized controlled trials demonstrated an approximately two-fold increase in hospitalizations for heart failure in COX-2 selective-treated patients and nonselective NSAID- treated patients compared to placebo-treated patients. In a Danish National Registry study of patients with heart failure, NSAID use increased the risk of MI, hospitalization for heart failure, and death. Additionally, fluid retention and edema have been observed in some patients treated with NSAIDs. Use of fenoprofen may blunt the CV effects of several therapeutic agents used to treat these medical conditions (e.g., diuretics, ACE inhibitors, or angiotensin receptor blockers [ARBs]) [see Drug Interactions (7)]. Avoid the use of NALFON in patients with severe heart failure unless the benefits are expected to outweigh the risk of worsening heart failure. If NALFON is used in patients with severe heart failure, monitor patients for signs of worsening heart failure. 5.6 Renal Toxicity and Hyperkalemia Renal Toxicity Long-term administration of NSAIDs has resulted in renal papillary necrosis and other renal injury. Renal toxicity has also been seen in patients in whom renal prostaglandins have a compensatory role in the maintenance of renal perfusion. In these patients, administration of an NSAID may cause a dose-dependent reduction in prostaglandin formation and, secondarily, in renal blood flow, which may precipitate overt renal decompensation. Patients at greatest risk of this reaction are those with impaired renal function, dehydration, hypovolemia, heart failure, liver dysfunction, those taking diuretics and ACE inhibitors or ARBs, and the elderly. Discontinuation of NSAID therapy is usually followed by recovery to the pretreatment state. No information is available from controlled clinical studies regarding the use of NALFON in patients with advanced renal disease. The renal effects of NALFON may hasten the progression of renal dysfunction in patients with preexisting renal disease. Correct volume status in dehydrated or hypovolemic patients prior to initiating NALFON. Monitor renal function in patients with renal or hepatic impairment, heart failure, dehydration, or hypovolemia during use of NALFON [see Drug Interactions (7)]. Avoid the use of NALFON in patients with advanced renal disease unless the benefits are expected to outweigh the risk of worsening renal function. If NALFON is used in patients with advanced renal disease, monitor patients for signs of worsening renal function. Hyperkalemia Increases in serum potassium concentration, including hyperkalemia, have been reported with use of NSAIDs, even in some patients without renal impairment. In patients with normal renal function, these effects have been attributed to a hyporeninemic­ hypoaldosteronism state. 5.7 Anaphylactic Reactions Fenoprofen has been associated with anaphylactic reactions in patients with and without known hypersensitivity to fenoprofen and in patients with aspirin-sensitive asthma [see Contraindications (4) and Warnings and Precautions (5.8)]. Seek emergency help if an anaphylactic reaction occurs. Reference ID: 3928124 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda 5.8 Exacerbation of Asthma Related to Aspirin Sensitivity A subpopulation of patients with asthma may have aspirin-sensitive asthma which may include chronic rhinosinusitis complicated by nasal polyps; severe, potentially fatal bronchospasm; and/or intolerance to aspirin and other NSAIDs. Because cross-reactivity between aspirin and other NSAIDs has been reported in such aspirin-sensitive patients, NALFON is contraindicated in patients with this form of aspirin sensitivity [see Contraindications (4)]. When NALFON is used in patients with preexisting asthma (without known aspirin sensitivity), monitor patients for changes in the signs and symptoms of asthma. 5.9 Serious Skin Reactions NSAIDs, including fenopropfen, can cause serious skin adverse reactions such as exfoliative dermatitis, Stevens-Johnson Syndrome (SJS), and toxic epidermal necrolysis (TEN), which can be fatal. These serious events may occur without warning. Inform patients about the signs and symptoms of serious skin reactions, and to discontinue the use of NALFON at the first appearance of skin rash or any other sign of hypersensitivity. NALFON is contraindicated in patients with previous serious skin reactions to NSAIDs [see Contraindications (4)]. 5.10 Premature Closure of Fetal Ductus Arteriosus Fenoprofen may cause premature closure of the fetal ductus arteriosus. Avoid use of NSAIDs, including NALFON, in pregnant women starting at 30 weeks of gestation (third trimester) [see Use in Specific Populations (8.1)]. 5.11 Hematologic Toxicity Anemia has occurred in NSAID-treated patients. This may be due to occult or gross blood loss, fluid retention, or an incompletely described effect on erythropoiesis. If a patient treated with NALFON has any signs or symptoms of anemia, monitor hemoglobin or hematocrit. NSAIDs, including NALFON, may increase the risk of bleeding events. Co-morbid conditions such as coagulation disorders, concomitant use of warfarin, other anticoagulants, antiplatelet agents (e.g., aspirin), serotonin reuptake inhibitors (SSRIs) and serotonin norepinephrine reuptake inhibitors (SNRIs) may increase this risk. Monitor these patients for signs of bleeding [see Drug Interactions (7)]. 5.12 Masking of Inflammation and Fever The pharmacological activity of NALFON in reducing inflammation, and possibly fever, may diminish the utility of diagnostic signs in detecting infections. 5.13 Laboratory Monitoring Because serious GI bleeding, hepatotoxicity, and renal injury can occur without warning symptoms or signs, consider monitoring patients on long-term NSAID treatment with a CBC and a chemistry profile periodically [see Warnings and Precautions (5.2, 5.3, 5.6)]. 5.14 Ocular Effects Studies to date have not shown changes in the eyes attributable to the administration of NALFON. However, adverse ocular effects have been observed with other anti-inflammatory drugs. Eye examinations, therefore, should be performed if visual disturbances occur in patients taking NALFON. 5.15 Central Nervous System Effects Caution should be exercised by patients whose activities require alertness if they experience CNS side effects while taking NALFON. 5.16 Impact on Hearing Since the safety of NALFON has not been established in patients with impaired hearing, these patients should have periodic tests of auditory function during prolonged therapy with NALFON. 6. ADVERSE REACTIONS The following adverse reactions are discussed in greater detail in other sections of the labeling: ● Cardiovascular Thrombotic Events [see Warnings and Precautions (5.1)] ● GI Bleeding, Ulceration and Perforation [see Warnings and Precautions (5.2)] ● Hepatotoxicity [see Warnings and Precautions (5.3)] ● Hypertension [see Warnings and Precautions (5.4)] ● Heart Failure and Edema [see Warnings and Precautions (5.5)] ● Renal Toxicity and Hyperkalemia [see Warnings and Precautions (5.6)] ● Anaphylactic Reactions [see Warnings and Precautions (5.7)] Reference ID: 3928124 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda ● Serious Skin Reactions [see Warnings and Precautions (5.9)] ● Hematologic Toxicity [see Warnings and Precautions (5.11)] 6.1 Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice. During clinical studies for rheumatoid arthritis, osteoarthritis, or mild to moderate pain and studies of pharmacokinetics, complaints were compiled from a checklist of potential adverse reactions, and the following data emerged. These encompass observations in 6,786 patients, including 188 observed for at least 52 weeks. For comparison, data are also presented from complaints received from the 266 patients who received placebo in these same trials. During short-term studies for analgesia, the incidence of adverse reactions was markedly lower than that seen in longer-term studies. Adverse Drug Reactions Reported in >1% of Patients During Clinical Trials Digestive System — During clinical trials with Nalfon, the most common adverse reactions were gastrointestinal in nature and occurred in 20.8% of patients receiving Nalfon as compared to 16.9% of patients receiving placebo. In descending order of frequency, these reactions included dyspepsia (10.3% Nalfon vs. 2.3% placebo), nausea (7.7% vs. 7.1%), constipation (7% vs. 1.5%), vomiting (2.6% vs. 1.9%), abdominal pain (2% vs. 1.1%), and diarrhea (1.8% vs. 4.1%). The drug was discontinued because of adverse gastrointestinal reactions in less than 2% of patients during premarketing studies. Nervous System — The most frequent adverse neurologic reactions were headache (8.7% vs. 7.5%) and somnolence (8.5% vs. 6.4%). Dizziness (6.5% vs. 5.6%), tremor (2.2% vs. 0.4%), and confusion (1.4% vs. none) were noted less frequently. Nalfon was discontinued in less than 0.5% of patients because of these side effects during premarketing studies. Skin and Appendages— Increased sweating (4.6% vs. 0.4%), pruritus (4.2% vs. 0.8%), and rash (3.7% vs. 0.4%) were reported. Nalfon was discontinued in about 1% of patients because of an adverse effect related to the skin during premarketing studies. Special Senses — Tinnitus (4.5% vs. 0.4%), blurred vision (2.2% vs. none), and decreased hearing (1.6% vs. none) were reported. Nalfon was discontinued in less than 0.5% of patients because of adverse effects related to the special senses during premarketing studies. Cardiovascular — Palpitations (2.5% vs. 0.4%). Nalfon was discontinued in about 0.5% of patients because of adverse cardiovascular reactions during premarketing studies. Miscellaneous — Nervousness (5.7% vs. 1.5%), asthenia (5.4% vs. 0.4%), peripheral edema (5.0% vs. 0.4%), dyspnea (2.8% vs. none), fatigue (1.7% vs. 1.5%), upper respiratory infection (1.5% vs. 5.6%), and nasopharyngitis (1.2% vs. none). Adverse Drug Reactions Reported in <1% of Patients During Clinical Trials Digestive System—Gastritis, peptic ulcer with/without perforation, gastrointestinal hemorrhage, anorexia, flatulence, dry mouth, and blood in the stool.

DRUG INTERACTIONS See Table 1 for clinically significant drug interactions with fenoprophen. Table 1: Clinically Significant Drug Interactions with Fenoprofen Drugs That Interfere with Hemostasis Clinical Impact: • Fenoprofen and anticoagulants such as warfarin have a synergistic effect on bleeding. The concomitant use of fenoprofen and anticoagulants have an increased risk of serious Reference ID: 3928124 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda bleeding compared to the use of either drug alone. • Serotonin release by platelets plays an important role in hemostasis. Case-control and cohort epidemiological studies showed that concomitant use of drugs that interfere with serotonin reuptake and an NSAID may potentiate the risk of bleeding more than an NSAID alone. Intervention: Monitor patients with concomitant use of NALFON with anticoagulants (e.g., warfarin), antiplatelet agents (e.g., aspirin), selective serotonin reuptake inhibitors (SSRIs), and serotonin norepinephrine reuptake inhibitors (SNRIs) for signs of bleeding [see Warnings and Precautions (5.11)]. Aspirin Clinical Impact: Controlled clinical studies showed that the concomitant use of NSAIDs and analgesic doses of aspirin does not produce any greater therapeutic effect than the use of NSAIDs alone. In a clinical study, the concomitant use of an NSAID and aspirin was associated with a significantly increased incidence of GI adverse reactions as compared to use of the NSAID alone [see Warnings and Precautions (5.2)]. Intervention: Concomitant use of NALFON and analgesic doses of aspirin is not generally recommended because of the increased risk of bleeding [see Warnings and Precautions (5.11)]. NALFON is not a substitute for low dose aspirin for cardiovascular protection. ACE Inhibitors, Angiotensin Receptor Blockers, and Beta-Blockers Clinical Impact: • NSAIDs may diminish the antihypertensive effect of angiotensin converting enzyme (ACE) inhibitors, angiotensin receptor blockers (ARBs), or beta-blockers (including propranolol). • In patients who are elderly, volume-depleted (including those on diuretic therapy), or have renal impairment, co-administration of an NSAID with ACE inhibitors or ARBs may result in deterioration of renal function, including possible acute renal failure. These effects are usually reversible. Intervention: • During concomitant use of NALFON and ACE-inhibitors, ARBs, or betablockers, monitor blood pressure to ensure that the desired blood pressure is obtained. • During concomitant use of NALFON ACE-inhibitors or ARBs in patients who are elderly, volume-depleted, or have impaired renal function, monitor for signs of worsening renal function [see Warnings and Precautions (5.6)]. • When these drugs are administered concomitantly, patients should be adequately hydrated. Assess renal function at the beginning of the concomitant treatment and periodically thereafter. Diuretics Clinical Impact: Clinical studies, as well as post-marketing observations, showed that NSAIDs reduced the natriuretic effect of loop diuretics (e.g., furosemide) and thiazide diuretics in some patients. This effect has been attributed to the NSAID inhibition of renal prostaglandin synthesis. Intervention: During concomitant use of NALFON with diuretics, observe patients for signs of worsening renal function, in addition to assuring diuretic efficacy including antihypertensive effects [see Warnings and Precautions (5.6)]. Digoxin Clinical Impact: The concomitant use of fenoprofen with digoxin has been reported to increase the serum concentration and prolong the half-life of digoxin. Intervention: During concomitant use of NALFON and digoxin, monitor serum digoxin levels. Lithium Clinical Impact: NSAIDs have produced elevations in plasma lithium levels and reductions in renal lithium clearance. The mean minimum lithium concentration increased 15%, and the renal clearance decreased by approximately 20%. This effect has been attributed to NSAID inhibition of renal prostaglandin synthesis. Intervention: During concomitant use of NALFON and lithium, monitor patients for signs of lithium toxicity. Methotrexate Clinical Impact: Concomitant use of NSAIDs and methotrexate may increase the risk for methotrexate toxicity (e.g., neutropenia, thrombocytopenia, renal dysfunction). Reference ID: 3928124 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda Intervention: During concomitant use of NALFON and methotrexate, monitor patients for methotrexate toxicity. Cyclosporine Clinical Impact: Concomitant use of NALFON and cyclosporine may increase cyclosporine’s nephrotoxicity. Intervention: During concomitant use of NALFON and cyclosporine, monitor patients for signs of worsening renal function. NSAIDs and Salicylates Clinical Impact: Concomitant use of fenoprofen with other NSAIDs or salicylates (e.g., diflunisal, salsalate) increases the risk of GI toxicity, with little or no increase in efficacy [see Warnings and Precautions (5.2)]. Intervention: The concomitant use of fenoprofen with other NSAIDs or salicylates is not recommended. Pemetrexed Clinical Impact: Concomitant use of NALFON and pemetrexed may increase the risk of pemetrexed­ associated myelosuppression, renal, and GI toxicity (see the pemetrexed prescribing information). Intervention: During concomitant use of NALFON and pemetrexed, in patients with renal impairment whose creatinine clearance ranges from 45 to 79 mL/min, monitor for myelosuppression, renal and GI toxicity. NSAIDs with short elimination half-lives (e.g., diclofenac, indomethacin) should be avoided for a period of two days before, the day of, and two days following administration of pemetrexed. In the absence of data regarding potential interaction between pemetrexed and NSAIDs with longer half-lives (e.g., meloxicam, nabumetone), patients taking these NSAIDs should interrupt dosing for at least five days before, the day of, and two days following pemetrexed administration. Phenobarbital Clinical Impact: Chronic administration of phenobarbital, a known enzyme inducer, may be associated with a decrease in the plasma half-life of fenoprofen. Intervention: When phenobarbital is added to or withdrawn from treatment, dosage adjustment of NALFON may be required. Hydantoins, sulfonamides, or sulfonylureas Clinical Impact: In vitro studies have shown that fenoprofen, because of its affinity for albumin, may displace from their binding sites other drugs that are also albumin bound, and this may lead to drug interactions. Theoretically, fenoprofen could likewise be displaced. Intervention: Patients receiving hydantoins, sulfonamides, or sulfonylureas should be observed for increased activity of these drugs and, therefore, signs of toxicity from these drugs. Drug/Laboratory Test Interactions Amerlex-M kit assay values of total and free triiodothyronine in patients receiving Nalfon have been reported as falsely elevated on the basis of a chemical cross-reaction that directly interferes with the assay. Thyroid-stimulating hormone, total thyroxine, and thyrotropin-releasing hormone response are not affected. Thus, results of the Amerlex-M kit assay should be interpreted with caution in these patients. 8. USE IN SPECIFIC POPULATIONS 8.1 Pregnancy Risk Summary Use of NSAIDs, including NALFON, during the third trimester of pregnancy increases the risk of premature closure of the fetal ductus arteriosus. Avoid use of NSAIDs, including NALFON, in pregnant women starting at 30 weeks of gestation (third trimester). There are no adequate and well-controlled studies of NALFON in pregnant women. Data from observational studies regarding potential embryofetal risks of NSAID use in women in the first or second trimesters of pregnancy are inconclusive. In the general U.S. population, all clinically recognized pregnancies, regardless of drug exposure, have a background rate of 2-4% for major malformations, and 15-20% for pregnancy loss. Reference ID: 3928124 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda In animal reproduction studies, embryo-fetal lethality and skeletal abnormalities were noted in offspring of pregnant rabbits following oral administration of fenoprofen during organogenesis at 0.6 times the maximum human daily dose of 3200 mg/day. However, there were no major malformations noted following oral administration of fenoprofen calcium to pregnant rats and rabbits during organogenesis at exposures up to 0.3 and 0.6 times the maximum human daily dose of 3200 mg/day. Based on animal data, prostaglandins have been shown to have an important role in endometrial vascular permeability, blastocyst implantation, and decidualization. In animal studies, administration of prostaglandin synthesis inhibitors such as fenoprofen, resulted in increased pre- and post-implantation loss. Clinical Considerations Labor or Delivery There are no studies on the effects of NALFON during labor or delivery. In animal studies, NSAIDS, including fenoprofen, inhibit prostaglandin synthesis, cause delayed parturition, and increase the incidence of stillbirth. Data Human Data There are no adequate and well-controlled studies of NALFON in pregnant women. Data from observational studies regarding potential embryofetal risks of NSAID use in women in the first or second trimesters of pregnancy are inconclusive. Animal data Pregnant rats were treated with fenoprofen using oral doses of 50 or 100 mg/kg (0.15 times and 0.3 times the maximum human daily dose (MHDD) of 3200 mg/day based on body surface area comparison) during the period of organogenesis. No major malformations were noted and there was no evidence of maternal toxicity at these doses, however, the exposures were below the exposures that will occur in humans. Pregnant rabbits were treated with fenoprofen using oral doses of 50 or 100 mg/kg (0.3 times and 0.6 times the MHDD of 3200 mg/day based on body surface area comparison) during the period of organogenesis. Maternal toxicity (mortality) was noted in the high dose animals. Although no major malformations were noted, there was an increased incidence of embryo-fetal lethality and skeletal abnormalities were present at 0.6 times the MHDD. Pregnant rats were treated from Gestation Day 14 through Post-Natal Day 20 with oral doses of fenoprofen of 6.25, 12.5, 25, 50, or 100 mg/kg (0.02, 0.04, 0.08, 0.15, or 0.3 times the MDD of 3200 mg/day based on body surface area comparison). All doses produced significant toxicity, including vaginal bleeding, prolonged parturition, increased stillbirths, and maternal deaths. Pregnant rats were treated from Gestation Day 6 through Gestation Day 19 and Post Partum Day 1 to 20 (excluding parturition) with an oral dose of fenoprofen of 100 mg/kg (0.3 times the MDD of 3200 mg/day based on body surface area comparison) demonstrated only a small increase in the incidence of impaired parturition despite the presence of maternal toxicity (gastrointestinal ulceration and renal toxicity). 8.2 Lactation Risk Summary In a published study, after a dose of 600 mg every 6 hours for 4 days in postpartum mothers, breastmilk fenoprofen levels were reportedly 1.6% of those in maternal plasma. The developmental and health benefits of breastfeeding should be considered along with the mother’s clinical need for NALFON and any potential adverse effects on the breastfed infant from the NALFON or from the underlying maternal condition. 8.3 Females and Males of Reproductive Potential Infertility Females Based on the mechanism of action, the use of prostaglandin-mediated NSAIDs, including NALFON, may delay or prevent rupture of ovarian follicles, which has been associated with reversible infertility in some women. Published animal studies have shown that administration of prostaglandin synthesis inhibitors has the potential to disrupt prostaglandinmediated follicular rupture required for ovulation. Small studies in women treated with NSAIDs have also shown a reversible delay in ovulation. Consider withdrawal of NSAIDs, including NALFON, in women who have difficulties conceiving or who are undergoing investigation of infertility. 8.4 Pediatric Use Safety and effectiveness in pediatric patients under the age of 18 have not been established. 8.5 Geriatric Use Elderly patients, compared to younger patients, are at greater risk for NSAID-associated serious cardiovascular, gastrointestinal, and/or renal adverse reactions. If the anticipated benefit for the elderly patient outweighs these potential risks, start dosing at the low end of the dosing range, and monitor patients for adverse effects [see Warnings and Precautions (5.1, 5.2, 5.3, 5.6, 5.13)]. Reference ID: 3928124 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda 10. OVERDOSAGE Symptoms following acute NSAID overdosages have been typically limited to lethargy, drowsiness, nausea, vomiting, and epigastric pain, which have been generally reversible with supportive care. Gastrointestinal bleeding has occurred. Hypertension, acute renal failure, respiratory depression, and coma have occurred, but were rare [see Warnings and Precautions (5.1, 5.2, 5.4, 5.6)]. Manage patients with symptomatic and supportive care following an NSAID overdosage. There are no specific antidotes. Consider emesis and/or activated charcoal (60 to 100 grams in adults, 1 to 2 grams per kg of body weight in pediatric patients) and/or osmotic cathartic in symptomatic patients seen within four hours of ingestion or in patients with a large overdosage (5 to 10 times the recommended dosage). Forced diuresis, alkalinization of urine, hemodialysis, or hemoperfusion may not be useful due to high protein binding. For additional information about overdosage treatment contact a poison control center (1-800-222-1222). 11. DESCRIPTION NALFON (fenoprofen calcium, USP) capsules is a nonsteroidal, anti-inflammatory drug available in 200 mg and 400 mg capsule form for oral administration. The 200 mg capsule is opaque yellow No. 97 cap and opaque white body, imprinted with “RX681” on the cap and body. The 400 mg capsule is opaque green cap and opaque blue body, imprinted with “NALFON 400 mg" on the cap and “EP 123” on the body. The chemical name is Benzenaecetic acid, α-methyl-3-phenoxy-, calcium salt dihydrate, (±)-. The molecular weight is 558.65. Its molecular formula is C30H26CaO6•2H2O, and it has the following chemical structure. structural formula Fenoprofen Calcium is an arylacetic acid derivative. It is a white crystalline powder. At 25°C, it dissolves to a 15 mg/mL solution in alcohol (95%). It is slightly soluble in water and insoluble in benzene.The pKa of fenoprofen calcium is 4.5 at 25°C. Nalfon capsules contain fenoprofen calcium as the dihydrate in an amount equivalent to 200 mg (0.826 mmol) or 400 mg (1.65 mmol) of fenoprofen.. Inactive ingredients in Nalfon capsules are crospovidone, magnesium stearate, sodium lauryl sulfate, and talc. In addition, the 200 mg capsules contain gelatin, titanium dioxide, yellow iron oxide, and red iron oxide, and the 400 mg capsules contain gelatin, D&C Yellow #10, FD&C Blue #1, FD&C Red #40, FD&C Yellow #6, and titanium dioxide. 12. CLINICAL PHARMACOLOGY 12.1 Mechanism of Action Fenoprofen has analgesic, anti-inflammatory, and antipyretic properties. The mechanism of action of NALFON, like that of other NSAIDs, is not completely understood but involves inhibition of cyclooxygenase (COX-1 and COX-2). Fenoprofen is a potent inhibitor of prostaglandin synthesis in vitro. Fenoprofen concentrations reached during therapy have produced in vivo effects. Prostaglandins sensitize afferent nerves and potentiate the action of bradykinin in inducing pain in animal models. Prostaglandins are mediators of inflammation. Because fenoprofen is an inhibitor of prostaglandin synthesis, its mode of action may be due to a decrease of prostaglandins in peripheral tissues. 12.3 Pharmacokinetics Absorption Under fasting conditions, fenoprofen is rapidly absorbed, and peak plasma levels of 50 mcg/L are achieved within 2 hours after oral administration of 600 mg doses. Good dose proportionality was observed between 200 and 600 mg doses in fasting male volunteers. Distribution Fenoprofen is highly bound (99%) to albumin. Reference ID: 3928124 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda Elimination Metabolism The plasma half-life is approximately 3 hours. Excretion About 90% of a single oral dose is eliminated within 24 hours as fenoprofen glucuronide and 4'-hydroxyfenoprofen glucuronide, the major urinary metabolites of fenoprofen. Specific Populations Geriatrics Peak plasma levels of fenoprofen in normal elderly volunteers were similar to those observed in normal young volunteers. Elderly volunteers had a mean plasma clearance of 2.2 L/hour while plasma clearance of fenoprofen in normal young volunteers ranged from 3 to 3.5 L/hour. The overall elimination rate constant, plasma half-life and ratio of renal to nonrenal clearance of fenoprofen was the same in elderly and young volunteers. The 30 to 60% decrease in plasma clearance is due to a decrease in the volume of distribution in the body. Drug Interaction Studies Aspirin: When NSAIDs were administered with aspirin, the protein binding of NSAIDs were reduced, although the clearance of free NSAID was not altered. The clinical significance of this interaction is not known. See Table 1 for clinically significant drug interactions of NSAIDs with aspirin [see Drug Interactions (7)]. Antacid: The concomitant administration of antacid (containing both aluminum and magnesium hydroxide) does not interfere with absorption of fenoprofen. 13 NONCLINICAL TOXICOLOGY 13.1 Carcinogenesis, Mutagenesis, and Impairment of Fertility Carcinogenesis Long-term studies in animals to evaluate the carcinogenic potential of fenoprofen have not been conducted. Mutagenesis Studies to evaluate the genotoxic potential of fenoprofen have not been conducted. Impairment of Fertility Female and Male rats were treated with 60 to 70 mg/kg/day or 120 to 150 mg/kg/day fenoprofen calcium via the diet (approximately 0.2 or 0.4 times the maximum human daily dose of 3200 mg/day based on body surface area comparison, respectively). Male rats were treated from 77 days prior to mating and during mating. Female rats were treated from 14 days prior to mating and through gestation. Pregnancy rates were slightly reduced in the low and high dose groups compared to controls. There was no adverse effect on implantations, resorptions, or live fetuses. 14. CLINICAL STUDIES NALFON is a nonsteroidal, anti-inflammatory, antiarthritic drug that also possesses analgesic and antipyretic activities. Its exact mode of action is unknown, but it is thought that prostaglandin synthetase inhibition is involved. Results in humans demonstrate that fenoprofen has both anti-inflammatory and analgesic actions. The emergence and degree of erythemic response were measured in adult male volunteers exposed to ultraviolet irradiation. The effects of NALFON, aspirin, and indomethacin were each compared with those of a placebo. All 3 drugs demonstrated antierythemic activity. In all patients with rheumatoid arthritis, the anti-inflammatory action of NALFON has been evidenced by relief of pain, increase in grip strength, and reductions in joint swelling, duration of morning stiffness, and disease activity (as assessed by both the investigator and the patient). The anti-inflammatory action of NALFON has also been evidenced by increased mobility (i.e., a decrease in the number of joints having limited motion). The use of NALFON in combination with gold salts or corticosteroids has been studied in patients with rheumatoid arthritis. The studies, however, were inadequate in demonstrating whether further improvement is obtained by adding NALFON to maintenance therapy with gold salts or steroids. Whether or not NALFON used in conjunction with partially effective doses of a corticosteroid has a “steroid-sparing” effect is unknown. In patients with osteoarthritis, the anti-inflammatory and analgesic effects of NALFON have been demonstrated by reduction in tenderness as a response to pressure and reductions in night pain, stiffness, swelling, and overall disease activity (as assessed by both the patient and the investigator). These effects have also been demonstrated by relief of pain with motion and at rest and increased range of motion in involved joints. In patients with rheumatoid arthritis and osteoarthritis, clinical studies have shown NALFON to be comparable to aspirin in controlling the aforementioned measures of disease activity, but mild gastrointestinal reactions (nausea, dyspepsia) and tinnitus Reference ID: 3928124 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda occurred less frequently in patients treated with NALFON than in aspirin-treated patients. It is not known whether NALFON causes less peptic ulceration than does aspirin. In patients with pain, the analgesic action of Nalfon has produced a reduction in pain intensity, an increase in pain relief, improvement in total analgesia scores, and a sustained analgesic effect. 16.

For current labeling information, please visit https://www.fda.gov/drugsatfda Medication Guide for Nonsteroidal Anti-inflammatory Drugs (NSAIDs) What is the most important information I should know about medicines called Nonsteroidal Anti- inflammatory Drugs (NSAIDs)? NSAIDs can cause serious side effects, including:  Increased risk of a heart attack or stroke that can lead to death. This risk may happen early in treatment and may increase: o with increasing doses of NSAIDs o with longer use of NSAIDs Do not take NSAIDs right before or after a heart surgery called a “coronary artery bypass graft (CABG)." Avoid taking NSAIDs after a recent heart attack, unless your healthcare provider tells you to. You may have an increased risk of another heart attack if you take NSAIDs after a recent heart attack.  Increased risk of bleeding, ulcers, and tears (perforation) of the esophagus (tube leading from the mouth to the stomach), stomach and intestines: o anytime during use o without warning symptoms o that may cause death The risk of getting an ulcer or bleeding increases with: o past history of stomach ulcers, or stomach or intestinal bleeding with use of NSAIDs o taking medicines called “corticosteroids”, “anticoagulants”, “SSRIs”, or “SNRIs” o increasing doses of NSAIDs o longer use of NSAIDs o smoking o drinking alcohol o older age o poor health o advanced liver disease o bleeding problems NSAIDs should only be used: o exactly as prescribed o at the lowest dose possible for your treatment o for the shortest time needed What are NSAIDs? NSAIDs are used to treat pain and redness, swelling, and heat (inflammation) from medical conditions such as different types of arthritis, menstrual cramps, and other types of short-term pain. Who should not take NSAIDs? Do not take NSAIDs:  if you have had an asthma attack, hives, or other allergic reaction with aspirin or any other NSAIDs.  right before or after heart bypass surgery. Before taking NSAIDS, tell your healthcare provider about all of your medical conditions, including if you:  have liver or kidney problems  have high blood pressure  have asthma  are pregnant or plan to become pregnant. Talk to your healthcare provivder if you are considering taking NSAIDs during pregnancy. You should not take NSAIDs after 29 weeks of pregnancy.  are breastfeeding or plan to breast feed. Tell your healthcare provider about all of the medicines you take, including prescription or over-the­ counter medicines, vitamins or herbal supplements. NSAIDs and some other medicines can interact with each other and cause serious side effects. Do not start taking any new medicine without talking to your healthcare provider first. What are the possible side effects of NSAIDs? NSAIDs can cause serious side effects, including: See “What is the most important information I should know about medicines called Nonsteroidal Anti- inflammatory Drugs (NSAIDs)?”  new or worse high blood pressure  heart failure  liver problems including liver failure Reference ID: 3928124 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda  kidney problems including kidney failure  low red blood cells (anemia)  life-threatening skin reactions  life-threatening allergic reactions  Other side effects of NSAIDs include: stomach pain, constipation, diarrhea, gas, heartburn, nausea, vomiting, and dizziness. Get emergency help right away if you get any of the following symptoms:  shortness of breath or trouble breathing  chest pain  weakness in one part or side of your body  slurred speech  swelling of the face or throat Stop taking your NSAID and call your healthcare provider right away if you get any of the following symptoms:  nausea  more tired or weaker than usual  diarrhea  itching  your skin or eyes look yellow  indigestion or stomach pain  flu-like symptoms  vomit blood  there is blood in your bowel movement or it is black and sticky like tar  unusual weight gain  skin rash or blisters with fever  swelling of the arms, legs, hands and feet If you take too much of your NSAID, call your healthcare provider or get medical help right away. These are not all the possible side effects of NSAIDs. For more information, ask your healthcare provider or pharmacist about NSAIDs. Call your doctor for medical advice about side effects. You may report side effects to FDA at 1-800-FDA-1088. Other information about NSAIDs  Aspirin is an NSAID but it does not increase the chance of a heart attack. Aspirin can cause bleeding in the brain, stomach, and intestines. Aspirin can also cause ulcers in the stomach and intestines.  Some NSAIDs are sold in lower doses without a prescription (over-the counter). Talk to your healthcare provider before using over-the-counter NSAIDs for more than 10 days. General information about the safe and effective use of NSAIDs Medicines are sometimes prescribed for purposes other than those listed in a Medication Guide. Do not use NSAIDs for a condition for which it was not prescribed. Do not give NSAIDs to other people, even if they have the same symptoms that you have. It may harm them. If you would like more information about NSAIDs, talk with your healthcare provider. You can ask your pharmacist or healthcare provider for information about NSAIDs that is written for health professionals.

1 TOLECTIN® DS (tolmetin sodium) Capsules TOLECTIN® 600 (tolmetin sodium) Tablets For Oral Administration Cardiovascular Risk • NSAIDs may cause an increased risk of serious cardiovascular thrombotic events, myocardial infarction, and stroke, which can be fatal. This risk may increase with duration of use. Patients with cardiovascular disease or risk factors for cardiovascular disease may be at greater risk. (See WARNINGS.) • TOLECTIN is contraindicated for the treatment of peri-operative pain in the setting of coronary artery bypass graft (CABG) surgery (see CONTRAINDICATIONS and WARNINGS.). Gastrointestinal Risk • NSAIDs cause an increased risk of serious gastrointestinal adverse events including bleeding, ulceration, and perforation of the stomach or intestines, which can be fatal. These events can occur at any time during use and without warning symptoms. Elderly patients are at greater risk for serious gastrointestinal events. (See WARNINGS.) DESCRIPTION TOLECTIN DS (tolmetin sodium) capsules for oral administration contain tolmetin sodium as the dihydrate in an amount equivalent to 400 mg of tolmetin. Each capsule contains 36 mg (1.568 mEq) of sodium and the following inactive ingredients: gelatin, magnesium stearate, corn starch, talc, FD&C Red No. 3, FD&C Yellow No. 6 and titanium dioxide. TOLECTIN 600 (tolmetin sodium) tablets for oral administration contain tolmetin sodium as the dihydrate in an amount equivalent to 600 mg of tolmetin. Each tablet contains 54 mg (2.35 mEq) of sodium and the following inactive ingredients: cellulose, silicon dioxide, crospovidone, hydroxypropyl methyl cellulose, magnesium stearate, polyethylene glycol, corn starch, titanium dioxide, FD&C Yellow No. 6 and D&C Yellow No. 10. This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda 2 The pKa of tolmetin is 3.5 and tolmetin sodium is freely soluble in water. Tolmetin sodium is a nonselective nonsteroidal anti-inflammatory agent. The structural formula is: Sodium 1-methyl-5-(4-methylbenzoyl)-1H-pyrrole-2-acetate dihydrate. CLINICAL PHARMACOLOGY Studies in animals have shown TOLECTIN (tolmetin sodium) to possess anti-inflammatory, analgesic, and antipyretic activity. In the rat, TOLECTIN prevents the development of experimentally induced polyarthritis and also decreases established inflammation. The mode of action for TOLECTIN is not known. However, studies in laboratory animals and man have demonstrated that the anti-inflammatory action of TOLECTIN is not due to pituitary-adrenal stimulation. TOLECTIN inhibits prostaglandin synthetase in vitro and lowers the plasma level of prostaglandin E in man. This reduction in prostaglandin synthesis may be responsible for the anti-inflammatory action. TOLECTIN does not appear to alter the course of the underlying disease in man. In patients with rheumatoid arthritis and in normal volunteers, tolmetin sodium is rapidly and almost completely absorbed with peak plasma levels being reached within 30-60 minutes after an oral therapeutic dose. In controlled studies, the time to reach peak tolmetin plasma concentration is approximately 20 minutes longer following administration of a 600 mg tablet, compared to an equivalent dose given as 200 mg tablets. The clinical meaningfulness of this finding, if any, is unknown. Tolmetin displays a biphasic elimination from the plasma consisting of a rapid phase with a half-life of 1 to 2 hours followed by a slower phase with a half-life of about 5 hours. Peak plasma levels of approximately 40 µg/mL are obtained with a 400 mg oral dose. Essentially all of the administered dose is recovered in the urine in 24 hours either as an inactive oxidative metabolite or as conjugates of tolmetin. An 18-day multiple This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda 3 dose study demonstrated no accumulation of tolmetin when compared with a single dose. In two fecal blood loss studies of 4 to 6 days duration involving 15 subjects each, TOLECTIN did not induce an increase in blood loss over that observed during a 4-day drug-free control period. In the same studies, aspirin produced a greater blood loss than occurred during the drug-free control period, and a greater blood loss than occurred during the TOLECTIN treatment period. In one of the two studies, indomethacin produced a greater fecal blood loss than occurred during the drug-free control period; in the second study, indomethacin did not induce a significant increase in blood loss. TOLECTIN is effective in treating both the acute flares and in the long-term management of the symptoms of rheumatoid arthritis, osteoarthritis and juvenile rheumatoid arthritis. In patients with either rheumatoid arthritis or osteoarthritis, TOLECTIN is as effective as aspirin and indomethacin in controlling disease activity, but the frequency of the milder gastrointestinal adverse effects and tinnitus was less than in aspirin-treated patients, and the incidence of central nervous system adverse effects was less than in indomethacin-treated patients. In patients with juvenile rheumatoid arthritis, TOLECTIN is as effective as aspirin in controlling disease activity, with a similar incidence of adverse reactions. Mean SGOT values, initially elevated in patients on previous aspirin therapy, remained elevated in the aspirin group and decreased in the TOLECTIN group. TOLECTIN has produced additional therapeutic benefit when added to a regimen of gold salts and, to a lesser extent, with corticosteroids. TOLECTIN should not be used in conjunction with salicylates since greater benefit from the combination is not likely, but the potential for adverse reactions is increased. INDICATIONS AND USAGE Carefully consider the potential benefits and risks of TOLECTIN and other treatment options before deciding to use TOLECTIN. Use the lowest effective dose for the shortest duration consistent with individual patient treatment goals (see WARNINGS). This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda 4 TOLECTIN (tolmetin sodium) is indicated for the relief of signs and symptoms of rheumatoid arthritis and osteoarthritis. TOLECTIN is indicated in the treatment of acute flares and the long-term management of the chronic disease. TOLECTIN is also indicated for treatment of juvenile rheumatoid arthritis. The safety and effectiveness of TOLECTIN have not been established in pediatric patients under 2 years of age (see PRECAUTIONS: Pediatric Use and DOSAGE AND ADMINSTRATION). CONTRAINDICATIONS TOLECTIN is contraindicated in patients with known hypersensitivity to tolmetin sodium. TOLECTIN should not be given to patients who have experienced asthma, urticaria or allergic-type reactions after taking aspirin or other NSAIDs. Severe, rarely fatal, anaphylactic-like reactions to NSAIDs have been reported in such patients (see WARNINGS: Anaphylactoid Reactions and PRECAUTIONS: Preexisting Asthma). TOLECTIN is contraindicated for the treatment of peri-operative pain in the setting of coronary artery bypass graft (CABG) surgery (see WARNINGS). WARNINGS Cardiovascular Effects Cardiovascular Thrombotic Events Clinical trials of several COX-2 selective and nonselective NSAIDS of up to three years duration have shown an increased risk of serious cardiovascular (CV) thrombotic events, myocardial infarction, and stroke, which can be fatal. All NSAIDs, both COX-2 selective and nonselective, may have a similar risk. Patients with known CV disease or risk factors for CV disease may be at greater risk. To minimize the potential risk for an adverse CV event in patients treated with an NSAID, the lowest effective dose should be used for the shortest duration possible. Physicians and patients should remain alert for the development of such events, even in the absence of previous CV symptoms. Patients should be informed about the signs and/or symptoms of serious CV events and the steps to take if they occur. There is no consistent evidence that concurrent use of aspirin mitigates the increased risk of serious CV thrombotic events associated with NSAID use. The concurrent use of aspirin and an NSAID does increase the risk of serious GI events (see This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda 5 WARNINGS: Gastrointestinal (GI) Effects—Risk of Ulceration, Bleeding, and Perforation). Two large, controlled, clinical trials of a COX-2 selective NSAID for the treatment of pain in the first 10 to 14 days following CABG surgery found an increased incidence of myocardial infarction and stroke (see CONTRAINDICATIONS). Hypertension NSAIDs, including TOLECTIN, can lead to onset of new hypertension or worsening of preexisting hypertension, either of which may contribute to the increased incidence of CV events. Patients taking thiazides or loop diuretics may have impaired response to these therapies when taking NSAIDs. NSAIDs, including TOLECTIN, should be used with caution in patients with hypertension. Blood pressure (BP) should be monitored closely during the initiation of NSAID treatment and throughout the course of therapy. Congestive Heart Failure and Edema Fluid retention and edema have been observed in some patients taking NSAIDs. TOLECTIN should be used with caution in patients with fluid retention or heart failure. Gastrointestinal (GI) Effects—Risk of Ulceration, Bleeding, and Perforation NSAIDs, including TOLECTIN, can cause serious gastrointestinal adverse events including inflammation, bleeding, ulceration, and perforation of the stomach, small intestine or large intestine, which can be fatal. These serious adverse events can occur at any time, with or without warning symptoms in patients treated with NSAIDs. Only one in five patients who develop a serious upper GI adverse event on NSAID therapy is symptomatic. Upper GI ulcers, gross bleeding, or perforation caused by NSAIDS occur in approximately 1% of patients treated for 3 to 6 months, and in about 2 to 4% of patients treated for one year. These trends continue with longer duration of use, increasing the likelihood of developing a serious GI event at some time during the course of therapy. However, even short-term therapy is not without risk. NSAIDs should be prescribed with extreme caution in those with a prior history of ulcer disease or gastrointestinal bleeding. Patients with a prior history of peptic ulcer disease and/or gastrointestinal bleeding who use NSAIDs have a greater than 10-fold increased risk for developing a GI bleed compared to patients with neither of these risk factors. Other factors that increase the risk for GI bleeding in patients treated This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda 6 with NSAIDs include concomitant use of oral corticosteroids or anticoagulants, longer duration of NSAID therapy, smoking, use of alcohol, older age, and poor general health status. Most spontaneous reports of fatal GI events are in elderly or debilitated patients and, therefore, special care should be taken in treating this population. To minimize the potential risk for an adverse GI event in patients treated with an NSAID, the lowest effective dose should be used for the shortest possible duration. Patients and physicians should remain alert for signs and symptoms of GI ulceration and bleeding during NSAID therapy and promptly initiate additional evaluation and treatment if a serious GI adverse event is suspected. This should include discontinuation of the NSAID until a serious GI adverse event is ruled out. For high- risk patients, alternate therapies that do not involve NSAIDs should be considered. Renal Effects Long-term administration of NSAIDs has resulted in renal papillary necrosis and other renal injury. including reports of aAcute interstitial nephritis with hematuria, proteinuria, and occasionally nephrotic syndrome have been reported in patients treated with TOLECTIN. Renal toxicity has also been seen in patients in whom renal prostaglandins have a compensatory role in the maintenance of renal perfusion. In these patients, administration of an NSAID may cause a dose-dependent reduction in prostaglandin formation and, secondarily, in renal blood flow, which may precipitate overt renal decompensation. Patients at greatest risk of this reaction are those with impaired renal function, heart failure, liver dysfunction, those taking diuretics and ACE inhibitors, and the elderly. Discontinuation of NSAID therapy is usually followed by recovery to the pretreatment state. Advanced Renal Disease No information is available from controlled clinical trials regarding the use of TOLECTIN in patients with advanced renal disease. Therefore, treatment with TOLECTIN is not recommended in these patients with advanced renal disease. If TOLECTIN therapy must be initiated, close monitoring of the patient’s renal function is advisable. Anaphylactoid Reactions As with other NSAIDs, anaphylactoid reactions may occur in patients with known prior exposure to TOLECTIN. TOLECTIN should not be given to patients with the aspirin triad. This symptom complex typically occurs in asthmatic patients who experience rhinitis with or without nasal polyps, or who exhibit severe, potentially This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda 7 fatal bronchospasm after taking aspirin or other NSAIDS (see CONTRAINDICATIONS and PRECAUTIONS: Preexisting Asthma). Emergency help should be sought in cases where an anaphylactoid reaction occurs. Skin Reactions NSAIDs, including TOLECTIN, can cause serious skin adverse events such as exfoliative dermatitis, Stevens-Johnson Syndrome (SJS), and toxic epidermal necrolysis (TEN), which can be fatal. These serious events may occur without warning. Patients should be informed about the signs and symptoms of serious skin manifestations and use of the drug should be discontinued at the first appearance of skin rash or any other sign of hypersensitivity. Pregnancy In late pregnancy, as with other NSAIDs, TOLECTIN should be avoided because it may cause premature closure of the ductus arteriosus (see also PRECAUTIONS: Pregnancy). PRECAUTIONS General TOLECTIN cannot be expected to substitute for corticosteroids or to treat corticosteroid insufficiency. Abrupt discontinuation of corticosteroids may lead to disease exacerbation. Patients on prolonged corticosteroid therapy should have their therapy tapered slowly if a decision is made to discontinue corticosteroids. The pharmacological activity of TOLECTIN in reducing fever and inflammation may diminish the utility of these diagnostic signs in detecting complications of presumed noninfectious, painful conditions. Ophthalmological Effects Because of ocular changes observed in animals and of reports of adverse eye findings with NSAIDs, it is recommended that patients who develop visual disturbances during treatment with TOLECTIN have ophthalmologic evaluations. Hepatic Effects Borderline elevations of one or more liver tests may occur in up to 15% of patients taking NSAIDs, including TOLECTIN. These laboratory abnormalities may progress, may remain unchanged, or may be transient with continuing therapy. Notable elevations of ALT or AST (approximately three or more times the upper limit of normal) have been reported in approximately 1% of patients in clinical trials with NSAIDs. In addition, rare cases of severe hepatic reactions, including jaundice and This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda 8 fatal fulminant hepatitis, liver necrosis, and hepatic failure, some of them with fatal outcomes have been reported. A patient with symptoms and/or signs suggesting liver dysfunction, or in whom an abnormal liver test has occurred should be evaluated for evidence of the development of a more severe hepatic reaction while on therapy with TOLECTIN. If clinical signs and symptoms consistent with liver disease develop, or if systemic manifestations occur (e.g., eosinophilia, rash, etc.), TOLECTIN should be discontinued. Hematological Effects Anemia is sometimes seen in patients receiving NSAIDs, including TOLECTIN. This may be due to fluid retention, occult or gross GI blood loss, or an incompletely described effect upon erythropoiesis. Patients on long-term treatment with NSAIDs, including TOLECTIN, should have their hemoglobin or hematocrit checked if they exhibit any signs or symptoms of anemia. NSAIDs inhibit platelet aggregation and have been shown to prolong bleeding time in some patients. Unlike aspirin, their effect on platelet function is quantitatively less, of shorter duration, and reversible. Patients receiving TOLECTIN who may be adversely affected by alterations in platelet function, such as those with coagulation disorders or patients receiving anticoagulants, should be carefully monitored. Preexisting Asthma Patients with asthma may have aspirin-sensitive asthma. The use of aspirin in patients with aspirin-sensitive asthma has been associated with severe bronchospasm which can be fatal. Since cross reactivity, including bronchospasm, between aspirin and other NSAIDs has been reported in such aspirin-sensitive patients, TOLECTIN should not be administered to patients with this form of aspirin sensitivity and should be used with caution in patients with preexisting asthma. Information for Patients Patients should be informed of the following information before initiating therapy with an NSAID and periodically during the course of ongoing therapy. Patients should also be encouraged to read the NSAID Medication Guide that accompanies each prescription dispensed. 1. TOLECTIN, like other NSAIDs, may cause serious CV side effects, such as MI or stroke, which may result in hospitalization and even death. Although serious CV events can occur without warning symptoms, patients should be alert for the signs and symptoms of chest pain, shortness of breath, weakness, This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda 9 slurring of speech, and should ask for medical advice when observing any indicative signs or symptoms. Patients should be apprised of the importance of this follow-up (see WARNINGS: Cardiovascular Effects). 2. TOLECTIN, like other NSAIDs, can cause GI discomfort and, rarely, serious GI side effects, such as ulcers and bleeding, which may result in hospitalization and even death. Although serious GI tract ulcerations and bleeding can occur without warning symptoms, patients should be alert for the signs and symptoms of ulcerations and bleeding, and should ask for medical advice when observing any indicative signs or symptoms including epigastric pain, dyspepsia, melena, and hematemesis Patients should be apprised of the importance of this follow-up (see WARNINGS: Gastrointestinal (GI) Effects—Risk of Ulceration, Bleeding, and Perforation). 3. TOLECTIN, like other NSAIDs, can cause serious skin side effects such as exfoliative dermatitis, SJS, and TEN, which may result in hospitalizations and even death. Although serious skin reactions may occur without warning, patients should be alert for the signs and symptoms of skin rash and blisters, fever, or other signs of hypersensitivity, such as itching, and should ask for medical advise when observing any indicative signs or symptoms. Patients should be advised to stop the drug immediately if they develop any type of rash and contact their physicians as soon as possible. 4. Patients should promptly report signs or symptoms of unexplained weight gain or edema to their physicians. 5. Patients should be informed of the warning signs and symptoms of hepatotoxicity (e.g., nausea, fatigue, lethargy, pruritus, jaundice, right upper quadrant tenderness, and “flu-like” symptoms). If these occur, patients should be instructed to stop therapy and seek immediate medical therapy. 6. Patients should be informed of the signs of an anaphylactoid reaction (e.g., difficulty breathing, swelling of the face or throat). If these occur, patients should be instructed to seek immediate emergency help (see WARNINGS). 7. In late pregnancy, as with other NSAIDs, TOLECTIN should be avoided because it may cause premature closure of the ductus arteriosus. This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda 10 Laboratory Tests Because serious GI tract ulcerations and bleeding can occur without warning symptoms, physicians should monitor for signs or symptoms of GI bleeding. Patients on long-term treatment with NSAIDs should have their CBC and a chemistry profile checked periodically. If clinical signs and symptoms consistent with liver or renal disease develop, systemic manifestations occur (e.g., eosinophilia, rash, etc.) or if abnormal liver tests persist or worsen, TOLECTIN should be discontinued. Drug Interactions ACE-inhibitors Reports suggest that NSAIDs may diminish the antihypertensive effect of ACE- inhibitors. This interaction should be given consideration in patients taking NSAIDs concomitantly with ACE-inhibitors. Aspirin As with other NSAIDs, concomitant administration of tolmetin sodium and aspirin is not generally recommended because of the potential of increased adverse effects. Diuretics Clinical studies, as well as post-marketing observations, have shown that NSAIDs can reduce the natriuretic effect of furosemide and thiazides in some patients. This response has been attributed to inhibition of renal prostaglandin synthesis. During concomitant therapy with NSAIDs, the patient should be observed closely for signs of renal failure, as well as to assure diuretic efficacy. Lithium NSAIDs have produced an elevation of plasma lithium levels and a reduction in renal lithium clearance. The mean minimum lithium concentration increased 15% and the renal clearance was decreased by approximately 20%. These effects have been attributed to inhibition of renal prostaglandin synthesis by the NSAID. Thus, when NSAIDs and lithium are administered concurrently, subjects should be observed carefully for signs of lithium toxicity. Methotrexate NSAIDs have been reported to competitively inhibit methotrexate accumulation in rabbit kidney slices. This may indicate that they could enhance the toxicity of methotrexate. Caution should be used when NSAIDs are administered concomitantly with methotrexate. This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda 11 Warfarin The effects of warfarin and NSAIDs on GI bleeding are synergistic, such that users of both drugs together have a risk of serious GI bleeding higher than users of either drug alone. The in vitro binding of warfarin to human plasma proteins is unaffected by tolmetin, and tolmetin does not alter the prothrombin time of normal volunteers. However, increased prothrombin time and bleeding have been reported in patients on concomitant TOLECTIN and warfarin therapy. Therefore, caution should be exercised when administering TOLECTIN to patients on anticoagulants. Hypoglycemic Agents In adult diabetic patients under treatment with either sulfonylureas or insulin there is no change in the clinical effects of either TOLECTIN or the hypoglycemic agents. Drug/Laboratory Test Interactions The metabolites of tolmetin sodium in urine have been found to give positive tests for proteinuria using tests which rely on acid precipitation as their endpoint (e.g., sulfosalicylic acid). No interference is seen in the tests for proteinuria using dye-impregnated commercially available reagent strips (e.g., Albustix®, Uristix®, etc.). Drug-Food Interactions In a controlled single-dose study, administration of TOLECTIN with milk had no effect on peak plasma tolmetin concentrations, but decreased total tolmetin bioavailability by 16%. When TOLECTIN was taken immediately after a meal, peak plasma tolmetin concentrations were reduced by 50% while total bioavailability was again decreased by 16%. Carcinogenesis, Mutagenesis, Impairment of Fertility Tolmetin sodium did not possess any carcinogenic liability in the following long-term studies: a 24-month study in rats at doses as high as 75 mg/kg/day, and an 18-month study in mice at doses as high as 50 mg/kg/day. No mutagenic potential of tolmetin sodium was found in the Ames Salmonella-Microsomal Activation Test. Reproductive studies revealed no impairment of fertility in animals. Effects on parturition have been shown, however, as with other prostaglandin inhibitors. This information is detailed in the Pregnancy section. This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda 12 Pregnancy Teratogenic Effects: Pregnancy Category C Reproduction studies in rats and rabbits at doses up to 50 mg/kg (1.5 times the maximum clinical dose based on a body weight of 60 kg) revealed no evidence of teratogenesis or impaired fertility due to TOLECTIN. However, animal reproduction studies are not always predictive of human response. There are no adequate and well- controlled studies in pregnant women. TOLECTIN should be used in pregnancy only if the potential benefit justifies the potential risk to the fetus. Nonteratogenic Effects Because of the known effects of NSAIDs on the fetal cardiovascular system (closure of ductus arteriosus), use during pregnancy (particularly late pregnancy) should be avoided. Labor and Delivery In rat studies with NSAIDs, as with other drugs known to inhibit prostaglandin synthesis, an increased incidence of dystocia, delayed parturition, and decreased pup survival occurred. The effects of TOLECTIN on labor and delivery in pregnant women are unknown. Nursing Mothers Tolmetin sodium has been shown to be secreted in human milk. Because of the potential for serious adverse reactions in nursing infants from tolmetin sodium, a decision should be made whether to discontinue nursing or to discontinue the drug, taking into account the importance of the drug to the mother. Pediatric Use Safety and effectiveness in pediatric patients below the age of 2 years have not been established. Geriatric Use As with any NSAIDs, caution should be exercised in treating the elderly (65 years and older). ADVERSE REACTIONS The adverse reactions which have been observed in clinical trials encompass observations in about 4370 patients treated with TOLECTIN (tolmetin sodium), over 800 of whom have undergone at least one year of therapy. These adverse reactions, reported below by body system, are among those typical of nonsteroidal anti-inflammatory drugs and, as expected, gastrointestinal complaints were most This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda 13 frequent. In clinical trials with TOLECTIN, about 10% of patients dropped out because of adverse reactions, mostly gastrointestinal in nature. Incidence Greater Than 1% The following adverse reactions which occurred more frequently than 1 in 100 were reported in controlled clinical trials. Gastrointestinal: Nausea (11%), dyspepsia,* gastrointestinal distress,* abdominal pain,* diarrhea,* flatulence,* vomiting,* constipation, gastritis, and peptic ulcer. Forty percent of the ulcer patients had a prior history of peptic ulcer disease and/or were receiving concomitant anti-inflammatory drugs including corticosteroids, which are known to produce peptic ulceration. Body as a Whole: Headache, * asthenia, * chest pain Cardiovascular: Elevated blood pressure, * edema* Central Nervous System: Dizziness, * drowsiness, depression Metabolic/Nutritional: Weight gain, * weight loss* Dermatologic: Skin irritation Special Senses: Tinnitus, visual disturbance Hematologic: Small and transient decreases in hemoglobin and hematocrit not associated with gastrointestinal bleeding have occurred. These are similar to changes reported with other nonsteroidal anti-inflammatory drugs. Urogenital: Elevated BUN, urinary tract infection *Reactions occurring in 3% to 9% of patients treated with TOLECTIN. Reactions occurring in fewer than 3% of the patients are unmarked. Incidence Less Than 1% (Causal Relationship Probable) The following adverse reactions were reported less frequently than 1 in 100 controlled clinical trials or were reported since marketing. The probability exists that there is a causal relationship between TOLECTIN and these adverse reactions. Gastrointestinal: Gastrointestinal bleeding with or without evidence of peptic ulcer, perforation, glossitis, stomatitis, hepatitis, liver function abnormalities. This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda 14 Body as a Whole: Anaphylactoid reactions, fever, lymphadenopathy, serum sickness Hematologic: Hemolytic anemia, thrombocytopenia, granulocytopenia, agranulocytosis Cardiovascular: Congestive heart failure in patients with marginal cardiac function. Dermatologic: Urticaria, purpura, erythema multiforme, toxic epidermal necrolysis Urogenital: Hematuria, proteinuria, dysuria, renal failure Incidence Less Than 1% (Causal Relationship Unknown) Other adverse reactions were reported less frequently than 1 in 100 in controlled clinical trials or were reported since marketing, but a causal relationship between TOLECTIN and the reaction could not be determined. These rarely reported reactions are being listed as alerting information for the physician since the possibility of a causal relationship cannot be excluded. Body as a Whole: Epistaxis Special Senses: Optic neuropathy, retinal and macular changes MANAGEMENT OF OVERDOSAGE In the event of overdosage, the stomach should be emptied by inducing vomiting or by gastric lavage followed by the administration of activated charcoal. DOSAGE AND ADMINISTRATION Carefully consider the potential benefits and risks of TOLECTIN and other treatment options before deciding to use TOLECTIN. Use the lowest effective dose for the shortest duration consistent with individual patient treatment goals (see WARNINGS). After observing the response to initial therapy with TOLECTIN, the dose and frequency should be adjusted to suit an individual patient’s needs. For the relief of rheumatoid arthritis or osteoarthritis, the recommended starting dose for adults is 400 mg three times daily (1200 mg daily), preferably including a dose on arising and a dose at bedtime. To achieve optimal therapeutic effect the dose should be adjusted according to the patient’s response after one or two weeks. Control is This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda 15 usually achieved at doses of 600-1800 mg daily in divided doses (generally t.i.d.). Doses larger than 1800 mg/day have not been studied and are not recommended. For the relief of juvenile rheumatoid arthritis, the recommended starting dose for pediatric patients (2 years and older) is 20 mg/kg/day in divided doses (t.i.d. or q.i.d.). When control has been achieved, the usual dose ranges from 15 to 30 mg/kg/day. Doses higher than 30 mg/kg/day have not been studied, and, therefore, are not recommended. A therapeutic response to TOLECTIN (tolmetin sodium) can be expected in a few days to a week. Progressive improvement can be anticipated during succeeding weeks of therapy. If gastrointestinal symptoms occur, TOLECTIN can be administered with antacids other than sodium bicarbonate. TOLECTIN bioavailability and pharmacokinetics are not significantly affected by acute or chronic administration of magnesium and aluminum hydroxides; however, bioavailability is affected by food or milk (see PRECAUTIONS: Drug-Food Interaction).

What is the most important information I should know about medicines called Non-Steroidal Anti-Inflammatory Drugs (NSAIDs)? NSAID medicines may increase the chance of a heart attack or stroke that can lead to death. This chance increases: • with longer use of NSAID medicines • in people who have heart disease NSAID medicines should never be used right before or after a heart surgery called a “coronary artery bypass graft (CABG).” NSAID medicines can cause ulcers and bleeding in the stomach and intestines at any time during treatment. Ulcers and bleeding: • can happen without warning symptoms • may cause death The chance of a person getting an ulcer or bleeding increases with: • taking medicines called “corticosteroids” and “anticoagulants” • longer use • smoking • drinking alcohol • older age • having poor health NSAID medicines should only be used: • exactly as prescribed • at the lowest dose possible for your treatment • for the shortest time needed What are Non-Steroidal Anti-Inflammatory Drugs (NSAIDs)? NSAID medicines are used to treat pain and redness, swelling, and heat (inflammation) from medical conditions such as: • different types of arthritis • menstrual cramps and other types of short-term pain This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda 17 Who should not take a Non-Steroidal Anti-Inflammatory Drug (NSAID)? Do not take an NSAID medicine: • if you had an asthma attack, hives, or other allergic reaction with aspirin or any other NSAID medicine • for pain right before or after heart bypass surgery Tell your healthcare provider: • about all your medical conditions. • about all of the medicines you take. NSAIDs and some other medicines can interact with each other and cause serious side effects. Keep a list of your medicines to show to your healthcare provider and pharmacist. • if you are pregnant. NSAID medicines should not be used by pregnant women late in their pregnancy. • if you are breastfeeding. Talk to your doctor. What are the possible side effects of Non-Steroidal Anti-Inflammatory Drugs (NSAIDs)? Serious side effects include: • heart attack • stroke • high blood pressure • heart failure from body swelling (fluid retention) • kidney problems including kidney failure • bleeding and ulcers in the stomach and intestine • low red blood cells (anemia) • life-threatening skin reactions • life-threatening allergic reactions • liver problems including liver failure • asthma attacks in people who have asthma Other side effects include: • stomach pain • constipation • diarrhea • gas • heartburn • nausea • vomiting • dizziness Get emergency help right away if you have any of the following symptoms: • shortness of breath or trouble breathing • slurred speech • chest pain • swelling of the face or throat • weakness in one part or side of your body This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda 18 Stop your NSAID medicine and call your healthcare provider right away if you have any of the following symptoms: • nausea • more tired or weaker than usual • itching • your skin or eyes look yellow • stomach pain • flu-like symptoms • vomit blood • there is blood in your bowel movement or it is black and sticky like tar • unusual weight gain • skin rash or blisters with fever • swelling of the arms and legs, hands and feet These are not all the side effects with NSAID medicines. Talk to your healthcare provider or pharmacist for more information about NSAID medicines. Other information about Non-Steroidal Anti-Inflammatory Drugs (NSAIDs) • Aspirin is an NSAID medicine but it does not increase the chance of a heart attack. Aspirin can cause bleeding in the brain, stomach, and intestines. Aspirin can also cause ulcers in the stomach and intestines. • Some of these NSAID medicines are sold in lower doses without a prescription (over-the-counter).

FLORONE® diflorasone diacetate cream, USP 0.05% Not For Ophthalmic Use DESCRIPTION Each gram of FLORONE Cream contains 0.5 mg diflorasone diacetate in a cream base. Chemically, diflorasone diacetate is: 6α,9-Difluoro- 11β, 17, 21-trihydroxy-16β-methylpregna-1,4-diene- 3,20-dione 17,21-diacetate. The structural formula is represented below: FLORONE Cream contains diflorasone diacetate in an emulsified and hydrophilic cream base of pro- pylene glycol, stearic acid, polysorbate 60, sorbitan monostearate and monooleate, sorbic acid, citric acid and water. The corticosteroid is formulated as a solution in the vehicle using 15 percent propylene glycol to optimize drug delivery. CLINICAL PHARMACOLOGY Topical corticosteroids share anti-inflammatory, anti- pruritic and vasoconstrictive actions. The mechanism of anti-inflammatory activity of the topical corticosteroids is unclear. Various laboratory methods, including vasoconstrictor assays, are used to compare and predict potencies and/or clinical effi- cacies of the topical corticosteroids. There is some evidence to suggest that a recognizable correlation exists between vasoconstrictor potency and thera- peutic efficacy in man. Pharmacokinetics The extent of percutaneous absorption of topical cor- ticosteroids is determined by many factors including the vehicle, the integrity of the epidermal barrier, and the use of occlusive dressings. Topical corticosteroids can be absorbed from normal intact skin. Inflammation and/or other disease pro- cesses in the skin increase percutaneous absorp- tion. Occlusive dressings substantially increase the percutaneous absorption of topical corticosteroids. Thus, occlusive dressings may be a valuable thera- peutic adjunct for treatment of resistant dermatoses. (See DOSAGE AND ADMINISTRATION.) Once absorbed through the skin, topical cortico- steroids are handled through pharmacokinetic path- ways similar to systemically administered cortico- steroids. Corticosteroids are bound to plasma proteins in varying degrees. They are metabolized primarily in the liver and are then excreted by the kidneys. Some of the topical corticosteroids and their metabolites are also excreted into the bile. INDICATIONS AND USAGE Topical corticosteroids are indicated for relief of the inflammatory and pruritic manifestations of cortico- steroid responsive dermatoses. CONTRAINDICATIONS Topical steroids are contraindicated in those patients with a history of hypersensitivity to any of the com- ponents of the preparation.

For current labeling information, please visit https://www.fda.gov/drugsatfda PRECAUTIONS General Systemic absorption of topical corticosteroids has produced reversible hypothalamic-pituitary-adrenal (HPA) axis suppression, manifestations of Cushing’s syndrome, hyperglycemia, and glucosuria in some patients. Conditions which augment systemic absorption include the application of the more potent steroids, use over large surface areas, prolonged use, and the addition of occlusive dressings. Therefore, patients receiving a large dose of a potent topical steroid applied to a large surface area or under an occlusive dressing should be evaluated periodically for evidence of HPA axis suppression by using the urinary free cortisol and ACTH stimulation tests. If HPA axis suppression is noted, an attempt should be made to withdraw the drug, to reduce the frequency of application, or to substitute a less potent steroid. Recovery of HPA axis function is generally prompt and complete upon discontinuation of the drug. Infrequently, signs and symptoms of steroid withdrawal may occur, requiring supplemental systemic corticosteroids. Pediatric patients may absorb proportionally larger amounts of topical corticosteroids and thus be more susceptible to systemic toxicity. (See PRE- CAUTIONS—Pediatric Use.) If irritation develops, topical corticosteroids should be discontinued and appropriate therapy instituted. In the presence of dermatological infections, the use of an appropriate antifungal or antibacterial agent should be instituted. If a favorable response does not occur promptly, the corticosteroid should be dis- continued until the infection has been adequately controlled. Information for the Patient Patients using topical corticosteroids should receive the following information and instructions: 1. This medication is to be used as directed by the physician. It is for external use only. Avoid con- tact with the eyes. 2. Patients should be advised not to use this med- ication for any disorder other than for which it was prescribed. 3. The treated skin area should not be bandaged or otherwise covered or wrapped as to be occlusive unless directed by the physician. 4. Patients should report any signs of local adverse reactions especially under occlusive dressing. 5. Parents of pediatric patients should be advised not to use tight-fitting diapers or plastic pants on an infant or child being treated in the diaper area, as these garments may constitute occlusive dressings. Laboratory Tests The following tests may be helpful in evaluating the HPA axis suppression: Urinary free cortisol test ACTH stimulation test Carcinogenesis, Mutagenesis, and Impairment of Fertility Long-term animal studies have not been performed to evaluate the carcinogenic potential or the effect of topical corticosteroids on fertility. Studies to determine mutagenicity with prednisolone and hydrocortisone have revealed negative results. Pregnancy Category C Corticosteroids are generally teratogenic in labora- tory animals when administered systemically at rela- tively low dosage levels. The more potent cortico- steroids have been shown to be teratogenic after dermal application in laboratory animals. There are no adequate and well-controlled studies in pregnant women on teratogenic effects from topically applied corticosteroids. Therefore, topical corticosteroids should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus. Drugs of this class should not be used extensively on preg- nant patients, in large amounts, or for prolonged periods of time. Nursing Mothers It is not known whether topical administration of corticosteroids could result in sufficient systemic absorption to produce detectable quantities in breast milk. Systemically administered corticosteroids are secreted into breast milk in quantities not likely to have a deleterious effect on the infant. Nevertheless, caution should be exercised when topical cortico- steroids are administered to a nursing woman. Pediatric Use Safety and effectiveness of FLORONE in pediatric patients have not been established. Because of a higher ratio of skin surface area to body mass, pedi- atric patients are at greater risk than adults of HPA- axis suppression when they are treated with topical corticosteroids. They are, therefore, also at greater risk of glucocorticosteroid insufficiency after with- drawal of treatment and of Cushing’s syndrome while on treatment. Adverse effects including striae have been reported with inappropriate use of topical corti- costeroids in pediatric patients. HPA-axis suppression, Cushing’s syndrome, and intracranial hypertension have been reported in pedi- atric patients receiving topical corticosteroids. Manifestations of adrenal suppression in pediatric patients include linear growth retardation, delayed weight gain, low plasma cortisol levels, and absence of response to ACTH stimulation. Manifestations of intracranial hypertension include bulging fontanelles, headaches, and bilateral papilledema. This label may not be the latest approved by FDA.

These reactions are listed in an approximate decreasing order of occurrence: Burning Itching Irritation Dryness Folliculitis Hypertrichosis Acneiform eruptions Hypopigmentation Perioral dermatitis Allergic contact dermatitis Maceration of the skin Secondary infection Skin atrophy Striae Miliaria OVERDOSAGE Topically applied corticosteroids can be absorbed in sufficient amounts to produce systemic effects. (See PRECAUTIONS.) DOSAGE AND ADMINISTRATION Topical corticosteroids are generally applied to the affected area as a thin film from one to four times daily depending on the severity of the condition. Occlusive dressings may be used for the manage- ment of psoriasis or recalcitrant conditions. If an infection develops, the use of occlusive dress- ings should be discontinued and appropriate antimi- crobial therapy instituted.

The chemical name for norethindrone is 17-Hydroxy-19-nor-17α-pregn-4-en-20-yn­ 3-one, and for ethinyl estradiol is 19-Nor-17α-pregna-1,3,5(10)-trien-20-yne-3,17­ diol. Their structural formulas are as follows: Norethindrone Ethinyl estradiol CLINICAL PHARMACOLOGY Combined Oral Contraceptives Combined oral contraceptives act by suppression of gonadotropins. Although the primary mechanism of this action is inhibition of ovulation, other alterations include changes in the cervical mucus (which increase the difficulty of sperm entry into the uterus) and the endometrium (which reduce the likelihood of implantation). INDICATIONS AND USAGE ORTHO-NOVUM® 7/7/7, ORTHO-NOVUM® 1/35, and MODICON® Tablets are indicated for the prevention of pregnancy in women who elect to use this product as a method of contraception. Oral contraceptives are highly effective. Table 1 lists the typical accidental pregnancy rates for users of combined oral contraceptives and other methods of contraception. The efficacy of these contraceptive methods, except sterilization, the IUD, and the NORPLANT® System depends upon the reliability with which they are used. Correct and consistent use of methods can result in lower failure rates.

CONTRAINDICATIONS Oral contraceptives should not be used in women who currently have the following conditions:  Thrombophlebitis or thromboembolic disorders Reference ID: 3383539 4 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda  A past history of deep vein thrombophlebitis or thromboembolic disorders  Known thrombophilic conditions  Cerebral vascular or coronary artery disease (current or history)  Valvular heart disease with complications  Persistent blood pressure values of  160 mm Hg systolic or  100 mg Hg diastolic96  Diabetes with vascular involvement  Headaches with focal neurological symptoms  Major surgery with prolonged immobilization  Known or suspected carcinoma of the breast  Carcinoma of the endometrium or other known or suspected estrogen-dependent neoplasia  Undiagnosed abnormal genital bleeding  Cholestatic jaundice of pregnancy or jaundice with prior pill use  Acute or chronic hepatocellular disease with abnormal liver function  Hepatic adenomas or carcinomas  Known or suspected pregnancy  Hypersensitivity to any component of this product WARNINGS Cigarette smoking increases the risk of serious cardiovascular events from combination oral contraceptive use. This risk increases with age, particularly in women over 35 years of age, and with the number of cigarettes smoked. For this reason, combination oral contraceptives, including ORTHO-NOVUM and MODICON, should not be used by women who are over 35 years of age and smoke. The use of oral contraceptives is associated with increased risks of several serious conditions including myocardial infarction, thromboembolism, stroke, hepatic neoplasia, and gallbladder disease, although the risk of serious morbidity or mortality is very small in healthy women without underlying risk factors. The risk of morbidity and mortality increases significantly in the presence of other underlying risk factors such as hypertension, hyperlipidemias, obesity and diabetes. Practitioners prescribing oral contraceptives should be familiar with the following information relating to these risks. The information contained in this package insert is principally based on studies carried out in patients who used oral contraceptives with higher formulations of Reference ID: 3383539 5 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda estrogens and progestogens than those in common use today. The effect of long-term use of the oral contraceptives with lower formulations of both estrogens and progestogens remains to be determined. Throughout this labeling, epidemiological studies reported are of two types: retrospective or case control studies and prospective or cohort studies. Case control studies provide a measure of the relative risk of a disease, namely, a ratio of the incidence of a disease among oral contraceptive users to that among nonusers. The relative risk does not provide information on the actual clinical occurrence of a disease. Cohort studies provide a measure of attributable risk, which is the difference in the incidence of disease between oral contraceptive users and nonusers. The attributable risk does provide information about the actual occurrence of a disease in the population (adapted from refs. 2 and 3 with the author’s permission). For further information, the reader is referred to a text on epidemiological methods. 1. Thromboembolic Disorders and Other Vascular Problems a. Myocardial Infarction An increased risk of myocardial infarction has been attributed to oral contraceptive use. This risk is primarily in smokers or women with other underlying risk factors for coronary artery disease such as hypertension, hypercholesterolemia, morbid obesity, and diabetes. The relative risk of heart attack for current oral contraceptive users has been estimated to be two to six.4–10 The risk is very low under the age of 30. Smoking in combination with oral contraceptive use has been shown to contribute substantially to the incidence of myocardial infarctions in women in their mid-thirties or older with smoking accounting for the majority of excess cases.11 Mortality rates associated with circulatory disease have been shown to increase substantially in smokers, especially in those 35 years of age and older, and in nonsmokers over the age of 40 among women who use oral contraceptives. (See Figure 1). Reference ID: 3383539 6 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda Figure 1. Circulatory Disease Mortality Rates per 100,000 Women-Years by Age, Smoking Status and Oral Contraceptive Use (Adapted from P.M. Layde and V. Beral, ref. #12.) Oral contraceptives may compound the effects of well-known risk factors, such as hypertension, diabetes, hyperlipidemias, age and obesity.13 In particular, some progestogens are known to decrease HDL cholesterol and cause glucose intolerance, while estrogens may create a state of hyperinsulinism.14–18 Oral contraceptives have been shown to increase blood pressure among users (see Section 9 in WARNINGS). Similar effects on risk factors have been associated with an increased risk of heart disease. Oral contraceptives must be used with caution in women with cardiovascular disease risk factors. b. Thromboembolism An increased risk of thromboembolic and thrombotic disease associated with the use of oral contraceptives is well established. Case control studies have found the relative risk of users compared to nonusers to be 3 for the first episode of superficial venous thrombosis, 4 to 11 for deep vein thrombosis or pulmonary embolism, and 1.5 to 6 for women with predisposing conditions for venous thromboembolic disease.2,3,19–24 Cohort studies have shown the relative risk to be somewhat lower, about 3 for new cases and about 4.5 for new cases requiring hospitalization.25 The risk of thromboembolic disease associated with oral contraceptives is not related to length of use and disappears after pill use is stopped.2 A two- to four-fold increase in relative risk of post-operative thromboembolic complications has been reported with the use of oral contraceptives.9 The relative risk of venous thrombosis in women who have predisposing conditions is twice that of women without such medical conditions.26 If feasible, oral contraceptives should be discontinued at least four weeks prior to and for two weeks after elective surgery of a type associated with an increase in risk of thromboembolism and during and Reference ID: 3383539 7 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda following prolonged immobilization. Since the immediate postpartum period is also associated with an increased risk of thromboembolism, oral contraceptives should be started no earlier than four weeks after delivery in women who elect not to breastfeed. c. Cerebrovascular diseases Oral contraceptives have been shown to increase both the relative and attributable risks of cerebrovascular events (thrombotic and hemorrhagic strokes), although, in general, the risk is greatest among older (>35 years), hypertensive women who also smoke. Hypertension was found to be a risk factor for both users and nonusers, for both types of strokes, and smoking interacted to increase the risk of stroke.27–29 In a large study, the relative risk of thrombotic strokes has been shown to range from 3 for normotensive users to 14 for users with severe hypertension.30 The relative risk of hemorrhagic stroke is reported to be 1.2 for non-smokers who used oral contraceptives, 2.6 for smokers who did not use oral contraceptives, 7.6 for smokers who used oral contraceptives, 1.8 for normotensive users and 25.7 for users with severe hypertension.30 The attributable risk is also greater in older women.3 d. Dose-related risk of vascular disease from oral contraceptives A positive association has been observed between the amount of estrogen and progestogen in oral contraceptives and the risk of vascular disease.31–33 A decline in serum high density lipoproteins (HDL) has been reported with many progestational agents.14–16 A decline in serum high density lipoproteins has been associated with an increased incidence of ischemic heart disease. Because estrogens increase HDL cholesterol, the net effect of an oral contraceptive depends on a balance achieved between doses of estrogen and progestogen and the activity of the progestogen used in the contraceptives. The activity and amount of both hormones should be considered in the choice of an oral contraceptive. Minimizing exposure to estrogen and progestogen is in keeping with good principles of therapeutics. For any particular estrogen/progestogen combination, the dosage regimen prescribed should be one which contains the least amount of estrogen and progestogen that is compatible with a low failure rate and the needs of the individual patient. New acceptors of oral contraceptive agents should be started on preparations containing the lowest estrogen content which is judged appropriate for the individual patient. e. Persistence of risk of vascular disease There are two studies which have shown persistence of risk of vascular disease for ever-users of oral contraceptives. In a study in the United States, the risk of developing myocardial infarction after discontinuing oral contraceptives persists for Reference ID: 3383539 8 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda at least 9 years for women 40–49 years who had used oral contraceptives for five or more years, but this increased risk was not demonstrated in other age groups.8 In another study in Great Britain, the risk of developing cerebrovascular disease persisted for at least 6 years after discontinuation of oral contraceptives, although excess risk was very small.34 However, both studies were performed with oral contraceptive formulations containing 50 micrograms or higher of estrogens. 2. Estimates of Mortality From Contraceptive Use One study gathered data from a variety of sources which have estimated the mortality rate associated with different methods of contraception at different ages (Table 2). These estimates include the combined risk of death associated with contraceptive methods plus the risk attributable to pregnancy in the event of method failure. Each method of contraception has its specific benefits and risks. The study concluded that with the exception of oral contraceptive users 35 and older who smoke, and 40 and older who do not smoke, mortality associated with all methods of birth control is low and below that associated with childbirth. The observation of an increase in risk of mortality with age for oral contraceptive users is based on data gathered in the 1970’s.35 Current clinical recommendation involves the use of lower estrogen dose formulations and a careful consideration of risk factors. In 1989, the Fertility and Maternal Health Drugs Advisory Committee was asked to review the use of oral contraceptives in women 40 years of age and over. The Committee concluded that although cardiovascular disease risks may be increased with oral contraceptive use after age 40 in healthy non-smoking women (even with the newer low-dose formulations), there are also greater potential health risks associated with pregnancy in older women and with the alternative surgical and medical procedures which may be necessary if such women do not have access to effective and acceptable means of contraception. The Committee recommended that the benefits of low-dose oral contraceptive use by healthy non-smoking women over 40 may outweigh the possible risks. Of course, older women, as all women who take oral contraceptives, should take an oral contraceptive which contains the least amount of estrogen and progestogen that is compatible with a low failure rate and individual patient needs.

Ory, ref. #35. * Deaths are birth-related † Deaths are method-related 3. Carcinoma of the Reproductive Organs and Breasts Numerous epidemiological studies have been performed on the incidence of breast, endometrial, ovarian and cervical cancer in women using oral contraceptives. The risk of having breast cancer diagnosed may be slightly increased among current and recent users of COCs. However, this excess risk appears to decrease over time after COC discontinuation and by 10 years after cessation the increased risk disappears. Some studies report an increased risk with duration of use while other studies do not and no consistent relationships have been found with dose or type of steroid. Some studies have found a small increase in risk for women who first use COCs before age 20. Most studies show a similar pattern of risk with COC use regardless of a woman’s reproductive history or her family breast cancer history. Breast cancers diagnosed in current or previous OC users tend to be less clinically advanced than in nonusers. Women who currently have or have had breast cancer should not use oral contraceptives because breast cancer is usually a hormonally-sensitive tumor. Some studies suggest that oral contraceptive use has been associated with an increase in the risk of cervical intraepithelial neoplasia in some populations of women.45–48 However, there continues to be controversy about the extent to which such findings may be due to differences in sexual behavior and other factors. In spite of many studies of the relationship between oral contraceptive use and breast and cervical cancers, a cause-and-effect relationship has not been established. 4. Hepatic Neoplasia Benign hepatic adenomas are associated with oral contraceptive use, although the incidence of benign tumors is rare in the United States. Indirect calculations have Reference ID: 3383539 10 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda estimated the attributable risk to be in the range of 3.3 cases/100,000 for users, a risk that increases after four or more years of use especially with oral contraceptives of higher dose.49 Rupture of benign, hepatic adenomas may cause death through intra-abdominal hemorrhage.50,51 Studies from Britain have shown an increased risk of developing hepatocellular carcinoma in long-term (>8 years) oral contraceptive users. However, these cancers are extremely rare in the U.S. and the attributable risk (the excess incidence) of liver cancers in oral contraceptive users approaches less than one per million users. 5. Ocular Lesions There have been clinical case reports of retinal thrombosis associated with the use of oral contraceptives. Oral contraceptives should be discontinued if there is unexplained partial or complete loss of vision; onset of proptosis or diplopia; papilledema; or retinal vascular lesions. Appropriate diagnostic and therapeutic measures should be undertaken immediately. 6. Oral Contraceptive Use Before or During Early Pregnancy Extensive epidemiological studies have revealed no increased risk of birth defects in women who have used oral contraceptives prior to pregnancy.56,57 The majority of recent studies also do not indicate a teratogenic effect, particularly in so far as cardiac concerned,55,56,58,59 anomalies and limb reduction defects are when taken inadvertently during early pregnancy. The administration of oral contraceptives to induce withdrawal bleeding should not be used as a test for pregnancy. Oral contraceptives should not be used during pregnancy to treat threatened or habitual abortion. It is recommended that for any patient who has missed two consecutive periods, pregnancy should be ruled out. If the patient has not adhered to the prescribed schedule, the possibility of pregnancy should be considered at the time of the first missed period. Oral contraceptive use should be discontinued if pregnancy is confirmed. 7. Gallbladder Disease Earlier studies have reported an increased lifetime relative risk of gallbladder surgery in users of oral contraceptives and estrogens.60,61 More recent studies, however, have shown that the relative risk of developing gallbladder disease among oral contraceptive users may be minimal.62–64 The recent findings of minimal risk may be related to the use of oral contraceptive formulations containing lower hormonal doses of estrogens and progestogens. Reference ID: 3383539 11 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda 8. Carbohydrate and Lipid Metabolic Effects Oral contraceptives have been shown to cause a decrease in glucose tolerance in a significant percentage of users.17 This effect has been shown to be directly related to estrogen dose.65 Progestogens increase insulin secretion and create insulin resistance, this effect varying with different progestational agents.17,66 However, in the non- diabetic woman, oral contraceptives appear to have no effect on fasting blood glucose.67 Because of these demonstrated effects, prediabetic and diabetic women in particular should be carefully monitored while taking oral contraceptives. A small proportion of women will have persistent hypertriglyceridemia while on the pill. As discussed earlier (see WARNINGS 1a and 1d), changes in serum triglycerides and lipoprotein levels have been reported in oral contraceptive users. 9. Elevated Blood Pressure Women with significant hypertension should not be started on hormonal contraception.92 An increase in blood pressure has been reported in women taking oral contraceptives68 and this increase is more likely in older oral contraceptive users69 and with extended duration of use.61 Data from the Royal College of General Practitioners12 and subsequent randomized trials have shown that the incidence of hypertension increases with increasing progestational activity. Women with a history of hypertension or hypertension-related diseases, or renal disease70 should be encouraged to use another method of contraception. If these women elect to use oral contraceptives, they should be monitored closely and if a clinically significant persistent elevation of blood pressure (BP) occurs ( 160 mm Hg systolic or  100 mm Hg diastolic) and cannot be adequately controlled, oral contraceptives should be discontinued. In general, women who develop hypertension during hormonal contraceptive therapy should be switched to a non-hormonal contraceptive. If other contraceptive methods are not suitable, hormonal contraceptive therapy may continue combined with antihypertensive therapy. Regular monitoring of BP throughout hormonal contraceptive therapy is recommended.96 For most women, elevated blood pressure will return to normal after stopping oral contraceptives, and there is no difference in the occurrence of hypertension between former and never users.68–71 10. Headache The onset or exacerbation of migraine or development of headache with a new pattern which is recurrent, persistent or severe requires discontinuation of oral contraceptives and evaluation of the cause. Reference ID: 3383539 12 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda 11. Bleeding Irregularities Breakthrough bleeding and spotting are sometimes encountered in patients on oral contraceptives, especially during the first three months of use. Nonhormonal causes should be considered and adequate diagnostic measures taken to rule out malignancy or pregnancy in the event of breakthrough bleeding, as in the case of any abnormal vaginal bleeding. If pathology has been excluded, time or a change to another formulation may solve the problem. In the event of amenorrhea, pregnancy should be ruled out. Some women may encounter post-pill amenorrhea or oligomenorrhea, especially when such a condition was preexistent. 12. Ectopic Pregnancy Ectopic as well as intrauterine pregnancy may occur in contraceptive failures. PRECAUTIONS 1. General Patients should be counseled that this product does not protect against HIV infection (AIDS) and other sexually transmitted diseases. 2. Physical Examination and Follow-Up It is good medical practice for all women to have annual history and physical examinations, including women using oral contraceptives. The physical examination, however, may be deferred until after initiation of oral contraceptives if requested by the woman and judged appropriate by the clinician. The physical examination should include special reference to blood pressure, breasts, abdomen and pelvic organs, including cervical cytology, and relevant laboratory tests. In case of undiagnosed, persistent or recurrent abnormal vaginal bleeding, appropriate measures should be conducted to rule out malignancy. Women with a strong family history of breast cancer or who have breast nodules should be monitored with particular care. 3. Lipid Disorders Women who are being treated for hyperlipidemias should be followed closely if they elect to use oral contraceptives. Some progestogens may elevate LDL levels and may render the control of hyperlipidemias more difficult. 4. Liver Function If jaundice develops in any woman receiving such drugs, the medication should be discontinued. Steroid hormones may be poorly metabolized in patients with impaired liver function. Reference ID: 3383539 13 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda 5. Fluid Retention Oral contraceptives may cause some degree of fluid retention. They should be prescribed with caution, and only with careful monitoring, in patients with conditions which might be aggravated by fluid retention. 6. Emotional Disorders Women with a history of depression should be carefully observed and the drug discontinued if depression recurs to a serious degree. 7. Contact Lenses Contact lens wearers who develop visual changes or changes in lens tolerance should be assessed by an ophthalmologist. 8. Drug Interactions Consult the labeling of concurrently-used drugs to obtain further information about interactions with hormonal contraceptives or the potential for enzyme alterations. Effects of Other Drugs on Combined Hormonal Contraceptives Substances decreasing the plasma concentrations of COCs and potentially diminishing the efficacy of COCs: Drugs or herbal products that induce certain enzymes, including cytochrome P450 3A4 (CYP3A4), may decrease the plasma concentrations of COCs and potentially diminish the effectiveness of CHCs or increase breakthrough bleeding. Some drugs or herbal products that may decrease the effectiveness of hormonal contraceptives include phenytoin, barbiturates, carbamazepine, bosentan, felbamate, griseofulvin, oxcarbazepine, rifampicin, topiramate, rifabutin, rufinamide, aprepitant, and products containing St. John’s wort. Interactions between hormonal contraceptives and other drugs may lead to breakthrough bleeding and/or contraceptive failure. Counsel women to use an alternative method of contraception or a back-up method when enzyme inducers are used with CHCs, and to continue back-up contraception for 28 days after discontinuing the enzyme inducer to ensure contraceptive reliability. Substances increasing the plasma concentrations of COCs: Co-administration of atorvastatin or rosuvastatin and certain COCs containing EE increase AUC values for EE by approximately 20-25%. Ascorbic acid and acetaminophen may increase plasma EE concentrations, possibly by inhibition of conjugation. CYP3A4 inhibitors such as itraconazole, voriconazole, fluconazole, grapefruit juice, or ketoconazole may increase plasma hormone concentrations. Reference ID: 3383539 14 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda Human immunodeficiency virus (HIV)/ Hepatitis C virus (HCV) protease inhibitors and non-nucleoside reverse transcriptase inhibitors: Significant changes (increase or decrease) in the plasma concentrations of estrogen and/or progestin have been noted in some cases of co-administration with HIV protease inhibitors (decrease [e.g., nelfinavir, ritonavir, darunavir/ritonavir, (fos)amprenavir/ritonavir, lopinavir/ritonavir, and tipranavir/ritonavir] or increase [e.g., indinavir and atazanavir/ritonavir]) /HCV protease inhibitors (decrease [e.g., boceprevir and telaprevir]) or with non-nucleoside reverse transcriptase inhibitors (decrease [e.g., nevirapine] or increase [e.g., etravirine]). Colesevelam: Colesevelam, a bile acid sequestrant, given together with a combination oral hormonal contraceptive, has been shown to significantly decrease the AUC of EE. A drug interaction between the contraceptive and colesevelam was decreased when the two drug products were given 4 hours apart. Effects of Combined Hormonal Contraceptives on Other Drugs COCs containing EE may inhibit the metabolism of other compounds (e.g., cyclosporine, prednisolone, theophylline, tizanidine, and voriconazole) and increase their plasma concentrations. COCs have been shown to decrease plasma concentrations of acetaminophen, clofibric acid, morphine, salicylic acid, temazepam and lamotrigine. Significant decrease in plasma concentration of lamotrigine has been shown, likely due to induction of lamotrigine glucuronidation. This may reduce seizure control; therefore, dosage adjustments of lamotrigine may be necessary. Women on thyroid hormone replacement therapy may need increased doses of thyroid hormone because serum concentrations of thyroid-binding globulin increases with use of COCs. 9. Interactions with Laboratory Tests Certain endocrine and liver function tests and blood components may be affected by oral contraceptives: a. Increased prothrombin and factors VII, VIII, IX, and X; decreased antithrombin 3; increased norepinephrine-induced platelet aggregability. b. Increased thyroid binding globulin (TBG) leading to increased circulating total thyroid hormone, as measured by protein-bound iodine (PBI), T4 by column or by radioimmunoassay. Free T3 resin uptake is decreased, reflecting the elevated TBG, free T4 concentration is unaltered. c. Other binding proteins may be elevated in serum. Reference ID: 3383539 15 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda d. Sex-binding globulins are increased and result in elevated levels of total circulating sex steroids and corticoids; however, free or biologically active levels remain unchanged. e. Triglycerides may be increased and levels of various other lipids and lipoproteins may be affected. f. Glucose tolerance may be decreased. g. Serum folate levels may be depressed by oral contraceptive therapy. This may be of clinical significance if a woman becomes pregnant shortly after discontinuing oral contraceptives. 10. Carcinogenesis See WARNINGS. 11. Pregnancy Pregnancy Category X. See CONTRAINDICATIONS and WARNINGS. 12. Nursing Mothers Small amounts of oral contraceptive steroids have been identified in the milk of nursing mothers and a few adverse effects on the child have been reported, including jaundice and breast enlargement. In addition, combined oral contraceptives given in the postpartum period may interfere with lactation by decreasing the quantity and quality of breast milk. If possible, the nursing mother should be advised not to use combined oral contraceptives but to use other forms of contraception until she has completely weaned her child. 13. Pediatric Use Safety and efficacy of ORTHO-NOVUM® Tablets and MODICON® Tablets have been established in women of reproductive age. Safety and efficacy are expected to be the same for postpubertal adolescents under the age of 16 and for users 16 years and older. Use of this product before menarche is not indicated. 14.

OVERDOSAGE Serious ill effects have not been reported following acute ingestion of large doses of oral contraceptives by young children. Overdosage may cause nausea, and withdrawal bleeding may occur in females. NON-CONTRACEPTIVE HEALTH BENEFITS The following non-contraceptive health benefits related to the use of combined oral contraceptives are supported by epidemiological studies which largely utilized oral contraceptive formulations containing estrogen doses exceeding 0.035 mg of ethinyl estradiol or 0.05 mg mestranol.73–78 Effects on menses:  increased menstrual cycle regularity  decreased blood loss and decreased incidence of iron deficiency anemia  decreased incidence of dysmenorrhea Effects related to inhibition of ovulation:  decreased incidence of functional ovarian cysts  decreased incidence of ectopic pregnancies Other effects:  decreased incidence of fibroadenomas and fibrocystic disease of the breast  decreased incidence of acute pelvic inflammatory disease  decreased incidence of endometrial cancer  decreased incidence of ovarian cancer DOSAGE AND ADMINISTRATION To achieve maximum contraceptive effectiveness, ORTHO-NOVUM® Tablets and MODICON® Tablets must be taken exactly as directed and at intervals not exceeding 24 hours. ORTHO-NOVUM® Tablets and MODICON® Tablets are available with the DIALPAK® Tablet Dispenser which is preset for a Sunday Start. Day 1 Start is also available. Reference ID: 3383539 19 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda Sunday Start When taking ORTHO-NOVUM® 7/7/7, ORTHO-NOVUM® 1/35, and MODICON® , the first "active" tablet should be taken on the first Sunday after menstruation begins. If the period begins on Sunday, the first "active" tablet should be taken that day. Take one active tablet daily for 21 days followed by one green "reminder" tablet daily for 7 days. After 28 tablets have been taken, a new course is started the next day (Sunday). For the first cycle of a Sunday Start regimen, another method of contraception such as a condom or spermicide should be used until after the first 7 consecutive days of administration. If the patient misses one (1) "active" tablet in Weeks 1, 2, or 3, the tablet should be taken as soon as she remembers. If the patient misses two (2) "active" tablets in Week 1 or Week 2, the patient should take two (2) tablets the day she remembers and two (2) tablets the next day; and then continue taking one (1) tablet a day until she finishes the pack. The patient should be instructed to use a back-up method of birth control such as a condom or spermicide if she has sex in the seven (7) days after missing pills. If the patient misses two (2) "active" tablets in the third week or misses three (3) or more "active" tablets in a row, the patient should continue taking one tablet every day until Sunday. On Sunday the patient should throw out the rest of the pack and start a new pack that same day. The patient should be instructed to use a back-up method of birth control if she has sex in the seven (7) days after missing pills. Complete instructions to facilitate patient counseling on proper pill usage may be found in the Detailed Patient Labeling ("How to Take the Pill" section). Day 1 Start The dosage of ORTHO-NOVUM® 7/7/7, ORTHO-NOVUM® 1/35, and MODICON®, for the initial cycle of therapy, is one "active" tablet administered daily from the 1st through the 21st day of the menstrual cycle, counting the first day of menstrual flow as "Day 1" followed by one green "reminder" tablet daily for 7 days. Tablets are taken without interruption for 28 days. After 28 tablets have been taken, a new course is started the next day. If the patient misses one (1) "active" tablet in Weeks 1, 2, or 3, the tablet should be taken as soon as she remembers. If the patient misses two (2) "active" tablets in Week 1 or Week 2, the patient should take two (2) tablets the day she remembers and two (2) tablets the next day; and then continue taking one (1) tablet a day until she finishes the pack. The patient should be instructed to use a back-up method of birth control such as a condom or spermicide if she has sex in the seven (7) days after missing pills. If the patient misses two (2) "active" tablets in the third week or misses Reference ID: 3383539 20 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda three (3) or more "active" tablets in a row, the patient should throw out the rest of the pack and start a new pack that same day. The patient should be instructed to use a back-up method of birth control if she has sex in the seven (7) days after missing pills. Complete instructions to facilitate patient counseling on proper pill usage may be found in the Detailed Patient Labeling ("How to Take the Pill" section). The use of ORTHO-NOVUM® 7/7/7, ORTHO-NOVUM® 1/35, and MODICON® for contraception may be initiated 4 weeks postpartum in women who elect not to breastfeed. When the tablets are administered during the postpartum period, the increased risk of thromboembolic disease associated with the postpartum period must be considered. (See CONTRAINDICATIONS and WARNINGS concerning thromboembolic disease. See also PRECAUTIONS: Nursing Mothers.) The possibility of ovulation and conception prior to initiation of medication should be considered. (See Discussion of Dose-Related Risk of Vascular Disease from Oral Contraceptives.) ADDITIONAL INSTRUCTIONS Breakthrough bleeding, spotting, and amenorrhea are frequent reasons for patients discontinuing oral contraceptives. In breakthrough bleeding, as in all cases of irregular bleeding from the vagina, nonfunctional causes should be borne in mind. In undiagnosed persistent or recurrent abnormal bleeding from the vagina, adequate diagnostic measures are indicated to rule out pregnancy or malignancy. If pathology has been excluded, time or a change to another formulation may solve the problem. Changing to an oral contraceptive with a higher estrogen content, while potentially useful in minimizing menstrual irregularity, should be done only if necessary since this may increase the risk of thromboembolic disease. Use of oral contraceptives in the event of a missed menstrual period: 1. If the patient has not adhered to the prescribed schedule, the possibility of pregnancy should be considered at the time of the first missed period and oral contraceptive use should be discontinued if pregnancy is confirmed. 2. If the patient has adhered to the prescribed regimen and misses two consecutive periods, pregnancy should be ruled out. Reference ID: 3383539 21 This label may not be the latest approved by FDA.

BRIEF SUMMARY PATIENT PACKAGE INSERT Oral contraceptives, also known as "birth control pills" or "the pill," are taken to prevent pregnancy and when taken correctly without missing any pills, have a failure Reference ID: 3383539 29 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda rate of approximately 1% per year. The typical failure rate is approximately 5% per year when women who miss pills are included. For most women oral contraceptives are also free of serious or unpleasant side effects. However, forgetting to take pills considerably increases the chances of pregnancy. For the majority of women, oral contraceptives can be taken safely. But there are some women who are at high risk of developing certain serious diseases that can be fatal or may cause temporary or permanent disability. The risks associated with taking oral contraceptives increase significantly if you:  smoke  have high blood pressure, diabetes, high cholesterol  have or have had clotting disorders, heart attack, stroke, angina pectoris, cancer of the breast or sex organs, jaundice or malignant or benign liver tumors. Although cardiovascular disease risks may be increased with oral contraceptive use after age 40 in healthy, non-smoking women (even with the newer low-dose formulations), there are also greater potential health risks associated with pregnancy in older women. You should not take the pill if you suspect you are pregnant or have unexplained vaginal bleeding. Do not use ORTHO-NOVUM® or MODICON® if you smoke cigarettes and are over 35 years old. Smoking increases your risk of serious cardiovascular side effects (heart and blood vessel problems) from combination oral contraceptives, including death from heart attack, blood clots or stroke. This risk increases with age and the number of cigarettes you smoke. Most side effects of the pill are not serious. The most common such effects are nausea, vomiting, bleeding between menstrual periods, weight gain, breast tenderness, and difficulty wearing contact lenses. These side effects, especially nausea and vomiting, may subside within the first three months of use. The serious side effects of the pill occur very infrequently, especially if you are in good health and are young. However, you should know that the following medical conditions have been associated with or made worse by the pill: 1. Blood clots in the legs (thrombophlebitis), lungs (pulmonary embolism), stoppage or rupture of a blood vessel in the brain (stroke), blockage of blood vessels in the heart (heart attack or angina pectoris) or other organs of the Reference ID: 3383539 30 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda body. As mentioned above, smoking increases the risk of heart attacks and strokes and subsequent serious medical consequences. 2. In rare cases, oral contraceptives can cause benign but dangerous liver tumors. These benign liver tumors can rupture and cause fatal internal bleeding. In addition, some studies report an increased risk of developing liver cancer. However, liver cancers are rare. 3. High blood pressure, although blood pressure usually returns to normal when the pill is stopped. The symptoms associated with these serious side effects are discussed in the detailed leaflet given to you with your supply of pills. Notify your healthcare professional if you notice any unusual physical disturbances while taking the pill. In addition, drugs such as rifampin, bosentan, as well as some seizure medicines and herbal preparations containing St. John’s wort (Hypericum perforatum) may decrease oral contraceptive effectiveness. Oral contraceptives may interact with lamotrigine (LAMICTAL®), a seizure medicine used for epilepsy. This may increase the risk of seizures so your healthcare professional may need to adjust the dose of lamotrigine. Various studies give conflicting reports on the relationship between breast cancer and oral contraceptive use. Oral contraceptive use may slightly increase your chance of having breast cancer diagnosed, particularly after using hormonal contraceptives at a younger age. After you stop using hormonal contraceptives, the chances of having breast cancer diagnosed begin to go back down. You should have regular breast examinations by a healthcare professional and examine your own breasts monthly. Tell your healthcare professional if you have a family history of breast cancer or if you have had breast nodules or an abnormal mammogram. Women who currently have or have had breast cancer should not use oral contraceptives because breast cancer is usually a hormone-sensitive tumor. Some studies have found an increase in the incidence of cancer of the cervix in women who use oral contraceptives. However, this finding may be related to factors other than the use of oral contraceptives. There is insufficient evidence to rule out the possibility that the pill may cause such cancers. Taking the combination pill provides some important non-contraceptive benefits. These include less painful menstruation, less menstrual blood loss and anemia, fewer pelvic infections, and fewer cancers of the ovary and the lining of the uterus. Reference ID: 3383539 31 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda Be sure to discuss any medical condition you may have with your healthcare professional. Your healthcare professional will take a medical and family history before prescribing oral contraceptives and will examine you. The physical examination may be delayed to another time if you request it and the healthcare professional believes that it is a good medical practice to postpone it. You should be reexamined at least once a year while taking oral contraceptives. Your pharmacist should have given you the detailed patient information labeling which gives you further information which you should read and discuss with your healthcare professional. This product (like all oral contraceptives) is intended to prevent pregnancy. It does not protect against transmission of HIV (AIDS) and other sexually transmitted diseases such as chlamydia, genital herpes, genital warts, gonorrhea, hepatitis B, and syphilis. HOW TO TAKE THE PILL IMPORTANT POINTS TO REMEMBER BEFORE YOU START TAKING YOUR PILLS: 1. BE SURE TO READ THESE DIRECTIONS: Before you start taking your pills. Anytime you are not sure what to do. 2. THE RIGHT WAY TO TAKE THE PILL IS TO TAKE ONE PILL EVERY DAY AT THE SAME TIME. If you miss pills you could get pregnant. This includes starting the pack late. The more pills you miss, the more likely you are to get pregnant. 3. MANY WOMEN HAVE SPOTTING OR LIGHT BLEEDING, OR MAY FEEL SICK TO THEIR STOMACH DURING THE FIRST 1-3 PACKS OF PILLS. If you feel sick to your stomach, do not stop taking the pill. The problem will usually go away. If it doesn’t go away, check with your healthcare professional. 4. MISSING PILLS CAN ALSO CAUSE SPOTTING OR LIGHT BLEEDING, even when you make up these missed pills. On the days you take 2 pills to make up for missed pills, you could also feel a little sick to your stomach. Reference ID: 3383539 32 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda 5. IF YOU HAVE VOMITING OR DIARRHEA, or IF YOU TAKE SOME MEDICINES, your pills may not work as well. Use a back-up method (such as a condom or spermicide) until you check with your healthcare professional. 6. IF YOU HAVE TROUBLE REMEMBERING TO TAKE THE PILL, talk to your healthcare professional about how to make pill taking easier or about using another method of birth control. 7.

INTRODUCTION Any woman who considers using oral contraceptives (the birth control pill or the pill) should understand the benefits and risks of using this form of birth control. This patient labeling will give you much of the information you will need to make this decision and will also help you determine if you are at risk of developing any of the serious side effects of the pill. It will tell you how to use the pill properly so that it will be as effective as possible. However, this labeling is not a replacement for a careful discussion between you and your healthcare professional. You should discuss the information provided in this labeling with him or her, both when you first start taking the pill and during your revisits. You should also follow your healthcare professional’s advice with regard to regular check-ups while you are on the pill. EFFECTIVENESS OF ORAL CONTRACEPTIVES Oral contraceptives or "birth control pills" or "the pill" are used to prevent pregnancy and are more effective than other non-surgical methods of birth control. When they are taken correctly without missing any pills, the chance of becoming pregnant is approximately 1% (1 pregnancy per 100 women per year of use). Typical failure rates are approximately 5% per year including women who do not always take the pills exactly as directed. The chance of becoming pregnant increases with each missed pill during a menstrual cycle. Reference ID: 3383539 41 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda In comparison, typical failure rates for other methods of birth control during the first year of use are as follows: Implant: <1% Male sterilization: <1% Injection: <1% Cervical Cap with spermicides: 20 to 40% IUD: 1 to 2% Condom alone (male): 14% Diaphragm with spermicides: 20% Condom alone (female): 21% Spermicides alone: 26% Periodic abstinence: 25% Vaginal sponge: 20 to 40% Withdrawal: 19% Female sterilization: <1% No methods: 85% WHO SHOULD NOT TAKE ORAL CONTRACEPTIVES Do not use ORTHO-NOVUM® or MODICON® if you smoke cigarettes and are over 35 years old. Smoking increases your risk of serious cardiovascular side effects (heart and blood vessel problems) from combination oral contraceptives, including death from heart attack, blood clots or stroke. This risk increases with age and the number of cigarettes you smoke. Some women should not use the pill. For example, you should not take the pill if you have any of the following conditions:  A history of heart attack or stroke  Blood clots in the legs (thrombophlebitis), lungs (pulmonary embolism), or eyes  A history of blood clots in the deep veins of your legs  An inherited problem that makes your blood clot more than normal  Chest pain (angina pectoris)  Known or suspected breast cancer or cancer of the lining of the uterus, cervix or vagina  Unexplained vaginal bleeding (until a diagnosis is reached by your healthcare professional)  Yellowing of the whites of the eyes or of the skin (jaundice) during pregnancy or during previous use of the pill  Liver tumor (benign or cancerous)  Known or suspected pregnancy  Valvular heart disease with complications  Severe hypertension  Diabetes with vascular involvement Reference ID: 3383539 42 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda  Headaches with focal neurological symptoms  If you plan to have surgery with prolonged bed rest  Hypersensitivity to any component of this product. Tell your healthcare professional if you have ever had any of these conditions. Your healthcare professional can recommend a safer method of birth control. OTHER CONSIDERATIONS BEFORE TAKING ORAL CONTRACEPTIVES Tell your healthcare professional if you have or have had:  Breast nodules, fibrocystic disease of the breast, an abnormal breast x-ray or mammogram  Diabetes  Elevated cholesterol or triglycerides  High blood pressure  Migraine or other headaches or epilepsy  Mental depression  Gallbladder, liver, heart or kidney disease  History of scanty or irregular menstrual periods Women with any of these conditions should be checked often by their healthcare professional if they choose to use oral contraceptives. Also, be sure to inform your healthcare professional if you smoke or are on any medications. RISKS OF TAKING ORAL CONTRACEPTIVES 1. Risk of developing blood clots Blood clots and blockage of blood vessels are one of the most serious side effects of taking oral contraceptives and can cause death or serious disability. In particular, a clot in the legs can cause thrombophlebitis and a clot that travels to the lungs can cause a sudden blocking of the vessel carrying blood to the lungs. Rarely, clots occur in the blood vessels of the eye and may cause blindness, double vision, or impaired vision. If you take oral contraceptives and need elective surgery, need to stay in bed for a prolonged illness or injury or have recently delivered a baby, you may be at risk of developing blood clots. You should consult your healthcare professional about stopping oral contraceptives three to four weeks before surgery and not taking oral Reference ID: 3383539 43 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda contraceptives for two weeks after surgery or during bed rest. You should also not take oral contraceptives soon after delivery of a baby. It is advisable to wait for at least four weeks after delivery if you are not breastfeeding or four weeks after a second trimester abortion. If you are breastfeeding, you should wait until you have weaned your child before using the pill. (See also the section on Breastfeeding in General Precautions.) The risk of circulatory disease in oral contraceptive users may be higher in users of high-dose pills and may be greater with longer duration of oral contraceptive use. In addition, some of these increased risks may continue for a number of years after stopping oral contraceptives. The risk of abnormal blood clotting increases with age in both users and nonusers of oral contraceptives, but the increased risk from the oral contraceptive appears to be present at all ages. For women aged 20 to 44, it is estimated that about 1 in 2,000 using oral contraceptives will be hospitalized each year because of abnormal clotting. Among nonusers in the same age group, about 1 in 20,000 would be hospitalized each year. For oral contraceptive users in general, it has been estimated that in women between the ages of 15 and 34 the risk of death due to a circulatory disorder is about 1 in 12,000 per year, whereas for nonusers the rate is about 1 in 50,000 per year. In the age group 35 to 44, the risk is estimated to be about 1 in 2,500 per year for oral contraceptive users and about 1 in 10,000 per year for nonusers. 2. Heart attacks and strokes Oral contraceptives may increase the tendency to develop strokes (stoppage or rupture of blood vessels in the brain) and angina pectoris and heart attacks (blockage of blood vessels in the heart). Any of these conditions can cause death or serious disability. Smoking greatly increases the possibility of suffering heart attacks and strokes. Furthermore, smoking and the use of oral contraceptives greatly increase the chances of developing and dying of heart disease. 3. Gallbladder disease Oral contraceptive users probably have a greater risk than nonusers of having gallbladder disease, although this risk may be related to pills containing high doses of estrogens. 4. Liver tumors Reference ID: 3383539 44 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda In rare cases, oral contraceptives can cause benign but dangerous liver tumors. These benign liver tumors can rupture and cause fatal internal bleeding. In addition, some studies report an increased risk of developing liver cancer. However, liver cancers are rare. 5. Cancer of the reproductive organs and breasts Various studies give conflicting reports on the relationship between breast cancer and oral contraceptive use. Oral contraceptive use may slightly increase your chance of having breast cancer diagnosed, particularly after using hormonal contraceptives at a younger age. After you stop using hormonal contraceptives, the chances of having breast cancer diagnosed begin to go back down. You should have regular breast examinations by a healthcare professional and examine your own breasts monthly. Tell your healthcare professional if you have a family history of breast cancer or if you have had breast nodules or an abnormal mammogram. Women who currently have or have had breast cancer should not use oral contraceptives because breast cancer is usually a hormone-sensitive tumor. Some studies have found an increase in the incidence of cancer of the cervix in women who use oral contraceptives. However, this finding may be related to factors other than the use of oral contraceptives. There is insufficient evidence to rule out the possibility that the pill may cause such cancers. ESTIMATED RISK OF DEATH FROM A BIRTH CONTROL METHOD OR PREGNANCY All methods of birth control and pregnancy are associated with a risk of developing certain diseases which may lead to disability or death. An estimate of the number of deaths associated with different methods of birth control and pregnancy has been calculated and is shown in the following table. Reference ID: 3383539 45 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda ANNUAL NUMBER OF BIRTH-RELATED OR METHOD-RELATED DEATHS ASSOCIATED WITH CONTROL OF FERTILITY PER 100,000 NONSTERILE WOMEN, BY FERTILITY CONTROL METHOD ACCORDING TO AGE Method of control and outcome 15-19 20-24 25-29 30-34 35-39 40-44 No fertility-control methods* 7.0 7.4 9.1 14.8 25.7 28.2 Oral contraceptives non-smoker† 0.3 0.5 0.9 1.9 13.8 31.6 Oral contraceptives smoker† 2.2 3.4 6.6 13.5 51.1 117.2 IUD† 0.8 0.8 1.0 1.0 1.4 1.4 Condom* 1.1 1.6 0.7 0.2 0.3 0.4 Diaphragm/ spermicide* 1.9 1.2 1.2 1.3 2.2 2.8 Periodic abstinence* 2.5 1.6 1.6 1.7 2.9 3.6 * Deaths are birth-related † Deaths are method-related In the above table, the risk of death from any birth control method is less than the risk of childbirth, except for oral contraceptive users over the age of 35 who smoke and pill users over the age of 40 even if they do not smoke. It can be seen in the table that for women aged 15 to 39, the risk of death was highest with pregnancy (7-26 deaths per 100,000 women, depending on age). Among pill users who do not smoke, the risk of death was always lower than that associated with pregnancy for any age group, although over the age of 40, the risk increases to 32 deaths per 100,000 women, compared to 28 associated with pregnancy at that age. However, for pill users who smoke and are over the age of 35, the estimated number of deaths exceeds those for other methods of birth control. If a woman is over the age of 40 and smokes, her estimated risk of death is four times higher (117/100,000 women) than the estimated risk associated with pregnancy (28/100,000 women) in that age group. The suggestion that women over 40 who do not smoke should not take oral contraceptives is based on information from older, higher-dose pills. An Advisory Committee of the FDA discussed this issue in 1989 and recommended that the benefits of low-dose oral contraceptive use by healthy, non-smoking women over 40 years of age may outweigh the possible risks. WARNING SIGNALS If any of these adverse effects occur while you are taking oral contraceptives, call your healthcare professional immediately:  Sharp chest pain, coughing of blood, or sudden shortness of breath (indicating a possible clot in the lung)  Pain in the calf (indicating a possible clot in the leg) Reference ID: 3383539 46 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda  Crushing chest pain or heaviness in the chest (indicating a possible heart attack)  Sudden severe headache or vomiting, dizziness or fainting, disturbances of vision or speech, weakness, or numbness in an arm or leg (indicating a possible stroke)  Sudden partial or complete loss of vision (indicating a possible clot in the eye)  Breast lumps (indicating possible breast cancer or fibrocystic disease of the breast; ask your healthcare professional to show you how to examine your breasts)  Severe pain or tenderness in the stomach area (indicating a possibly ruptured liver tumor)  Difficulty in sleeping, weakness, lack of energy, fatigue, or change in mood (possibly indicating severe depression)  Jaundice or a yellowing of the skin or eyeballs, accompanied frequently by fever, fatigue, loss of appetite, dark colored urine, or light colored bowel movements (indicating possible liver problems) SIDE EFFECTS OF ORAL CONTRACEPTIVES 1. Vaginal bleeding Irregular vaginal bleeding or spotting may occur while you are taking the pills. Irregular bleeding may vary from slight staining between menstrual periods to breakthrough bleeding which is a flow much like a regular period. Irregular bleeding occurs most often during the first few months of oral contraceptive use, but may also occur after you have been taking the pill for some time. Such bleeding may be temporary and usually does not indicate any serious problems. It is important to continue taking your pills on schedule. If the bleeding occurs in more than one cycle or lasts for more than a few days, talk to your healthcare professional. 2. Contact lenses If you wear contact lenses and notice a change in vision or an inability to wear your lenses, contact your healthcare professional. 3. Fluid retention Oral contraceptives may cause edema (fluid retention) with swelling of the fingers or ankles and may raise your blood pressure. If you experience fluid retention, contact your healthcare professional. 4. Melasma A spotty darkening of the skin is possible, particularly of the face, which may persist. Reference ID: 3383539 47 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda 5. Other side effects Other side effects may include nausea, vomiting and diarrhea, muscle cramps, change in appetite, headache, nervousness, depression, dizziness, loss of scalp hair, rash, vaginal infections, pancreatitis, skin sensitivity to the sun or ultraviolet and allergic reactions. If any of these side effects bother you, call your healthcare professional. GENERAL PRECAUTIONS 1. Missed periods and use of oral contraceptives before or during early pregnancy There may be times when you may not menstruate regularly after you have completed taking a cycle of pills. If you have taken your pills regularly and miss one menstrual period, continue taking your pills for the next cycle but be sure to inform your healthcare professional before doing so. If you have not taken the pills daily as instructed and missed a menstrual period, you may be pregnant. If you missed two consecutive menstrual periods, you may be pregnant. Check with your healthcare professional immediately to determine whether you are pregnant. Do not continue to take oral contraceptives until you are sure you are not pregnant, but continue to use another method of contraception. There is no conclusive evidence that oral contraceptive use is associated with an increase in birth defects, when taken inadvertently during early pregnancy. Previously, a few studies had reported that oral contraceptives might be associated with birth defects, but these findings have not been seen in more recent studies. Nevertheless, oral contraceptives should not be used during pregnancy. You should check with your healthcare professional about risks to your unborn child of any medication taken during pregnancy. 2. While breastfeeding If you are breastfeeding, consult your healthcare professional before starting oral contraceptives. Some of the drug will be passed on to the child in the milk. A few adverse effects on the child have been reported, including yellowing of the skin (jaundice) and breast enlargement. In addition, combined oral contraceptives may decrease the amount and quality of your milk. If possible, do not use combined oral contraceptives while breastfeeding. You should use another method of contraception since breastfeeding provides only partial protection from becoming pregnant and this partial protection decreases significantly as you breastfeed for longer periods of time. Reference ID: 3383539 48 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda You should consider starting combined oral contraceptives only after you have weaned your child completely. 3. Laboratory tests If you are scheduled for any laboratory tests, tell your healthcare professional you are taking birth control pills. Certain blood tests may be affected by birth control pills. 4. Drug interactions Tell your healthcare provider about all medicines and herbal products that you take. Some medicines and herbal products may make hormonal birth control less effective, including, but not limited to: • certain seizure medicines (carbamazepine, felbamate, oxcarbazepine, phenytoin, rufinamide, and topiramate) • aprepitant • barbiturates • bosentan • colesevelam • griseofulvin • certain combinations of HIV medicines (nelfinavir, ritonavir, ritonavir­ boosted protease inhibitors) • certain non nucleoside reverse transcriptase inhibitors (nevirapine) • rifampin and rifabutin • St. John’s wort Use another birth control method (such as a condom and spermicide or diaphragm and spermicide) when you take medicines that may make ORTHO-NOVUM® 7/7/7, ORTHO-NOVUM® 1/35, or MODICON® less effective. Some medicines and grapefruit juice may increase your level of the hormone ethinyl estradiol if used together, including: • acetaminophen • ascorbic acid • medicines that affect how your liver breaks down other medicines (itraconazole, ketoconazole, voriconazole, and fluconazole) Reference ID: 3383539 49 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda • certain HIV medicines (atazanavir, indinavir) • atorvastatin • rosuvastatin • etravirine Hormonal birth control methods may interact with lamotrigine, a seizure medicine used for epilepsy. This may increase the risk of seizures, so your healthcare provider may need to adjust the dose of lamotrigine. Women on thyroid replacement therapy may need increased doses of thyroid hormone. Know the medicines you take. Keep a list of them to show your doctor and pharmacist when you get a new medicine. 5. Sexually transmitted diseases This product (like all oral contraceptives) is intended to prevent pregnancy. It does not protect against transmission of HIV (AIDS) and other sexually transmitted diseases such as chlamydia, genital herpes, genital warts, gonorrhea, hepatitis B, and syphilis. HOW TO TAKE THE PILL IMPORTANT POINTS TO REMEMBER BEFORE YOU START TAKING YOUR PILLS: 1. BE SURE TO READ THESE DIRECTIONS: Before you start taking your pills. Anytime you are not sure what to do. a. THE RIGHT WAY TO TAKE THE PILL IS TO TAKE ONE PILL EVERY DAY AT THE SAME TIME. If you miss pills you could get pregnant. This includes starting the pack late. The more pills you miss, the more likely you are to get pregnant. b. MANY WOMEN HAVE SPOTTING OR LIGHT BLEEDING, OR MAY FEEL SICK TO THEIR STOMACH DURING THE FIRST 1-3 PACKS OF PILLS. If you feel sick to your stomach, do not stop taking the pill. The problem will usually go away. If it doesn’t go away, check with your healthcare professional. Reference ID: 3383539 50 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda c. MISSING PILLS CAN ALSO CAUSE SPOTTING OR LIGHT BLEEDING, even when you make up these missed pills. On the days you take 2 pills to make up for missed pills, you could also feel a little sick to your stomach. d. IF YOU HAVE VOMITING OR DIARRHEA, or IF YOU TAKE SOME MEDICINES, including some antibiotics, your pills may not work as well. Use a back-up method (such as a condom or spermicide) until you check with your healthcare professional. e. IF YOU HAVE TROUBLE REMEMBERING TO TAKE THE PILL, talk to your healthcare professional about how to make pill taking easier or about using another method of birth control. f. IF YOU HAVE ANY QUESTIONS OR ARE UNSURE ABOUT THE INFORMATION IN THIS LEAFLET, call your healthcare professional. BEFORE YOU START TAKING YOUR PILLS 1. DECIDE WHAT TIME OF DAY YOU WANT TO TAKE YOUR PILL. It is important to take it at about the same time every day. 2. LOOK AT YOUR PILL PACK. The pill pack has 21 "active" pills (with hormones) to take for 3 weeks. This is followed by 1 week of green "reminder" pills (without hormones). ORTHO-NOVUM® 7/7/7: There are 7 white "active" pills, 7 light peach "active" pills, 7 peach "active" pills and 7 green "reminder" pills.

FINALLY, IF YOU ARE STILL NOT SURE WHAT TO DO ABOUT THE PILLS YOU HAVE MISSED: Use a BACK-UP METHOD anytime you have sex. KEEP TAKING ONE "ACTIVE" PILL EACH DAY until you can reach your healthcare professional. PREGNANCY DUE TO PILL FAILURE Combined Oral Contraceptives The incidence of pill failure resulting in pregnancy is approximately one percent (i.e., one pregnancy per 100 women per year) if taken every day as directed, but more typical failure rates are 5%. If failure does occur, the risk to the fetus is minimal. PREGNANCY AFTER STOPPING THE PILL There may be some delay in becoming pregnant after you stop using oral contraceptives, especially if you had irregular menstrual cycles before you used oral contraceptives. It may be advisable to postpone conception until you begin menstruating regularly once you have stopped taking the pill and desire pregnancy. There does not appear to be any increase in birth defects in newborn babies when pregnancy occurs soon after stopping the pill. OVERDOSAGE Serious ill effects have not been reported following ingestion of large doses of oral contraceptives by young children. Overdosage may cause nausea and withdrawal bleeding in females. In case of overdosage, contact your healthcare professional or pharmacist. OTHER INFORMATION Reference ID: 3383539 57 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda Your healthcare professional will take a medical and family history before prescribing oral contraceptives and will examine you. The physical examination may be delayed to another time if you request it and the healthcare professional believes that it is a good medical practice to postpone it. You should be reexamined at least once a year. Be sure to inform your healthcare professional if there is a family history of any of the conditions listed previously in this leaflet. Be sure to keep all appointments with your healthcare professional, because this is a time to determine if there are early signs of side effects of oral contraceptive use. Do not use the drug for any condition other than the one for which it was prescribed. This drug has been prescribed specifically for you; do not give it to others who may want birth control pills. HEALTH BENEFITS FROM ORAL CONTRACEPTIVES In addition to preventing pregnancy, use of combined oral contraceptives may provide certain benefits. They are:  menstrual cycles may become more regular  blood flow during menstruation may be lighter and less iron may be lost. Therefore, anemia due to iron deficiency is less likely to occur.  pain or other symptoms during menstruation may be encountered less frequently  ectopic (tubal) pregnancy may occur less frequently  noncancerous cysts or lumps in the breast may occur less frequently  acute pelvic inflammatory disease may occur less frequently  oral contraceptive use may provide some protection against developing two forms of cancer: cancer of the ovaries and cancer of the lining of the uterus. If you want more information about birth control pills, ask your healthcare professional. They have a more technical leaflet called the Professional Labeling, which you may wish to read. Store at 25°C (77°F), excursions permitted to 15°–30°C (59°–86°F).

DrytecTM (Technetium Tc99m Generator) For the Production of Sodium Pertechnetate Tc99m Injection Diagnostic Radiopharmaceutical For intravenous use only Rx ONLY DESCRIPTION The Drytec (Technetium Tc99m Generator) is prepared with fission-produced molybdenum Mo99 adsorbed on alumina in a lead-shielded column and provides a means for obtaining sterile pyrogen-free solutions of Sodium Pertechnetate Tc99m Injection in sodium chloride. The eluate should be crystal clear. With a pH of 4.5-7.5, hydrochloric acid and/or sodium hydroxide may have been used for Mo99 solution pH adjustment. Over the life of the generator, each elution will provide a yield of > 90% of the theoretical amount of technetium Tc99m available from the molybdenum Mo99 on the generator column. Each eluate of the generator should not contain more than 0.0056 MBq (0.15 µCi) of molybdenum Mo99 per 37 MBq (1 mCi) of technetium Tc99m per administered dose at the time of administration, and not more than 10 µg of aluminum per mL of the generator eluate, both of which must be determined by the user before administration. Since the eluate does not contain an antimicrobial agent, it should not be used after twelve hours from the time of generator elution. PHYSICAL CHARACTERISTICS Technetium Tc99m decays by an isomeric transition with a physical half-life of 6.02 hours. The principal photon that is useful for detection and imaging studies is listed in Table 1. Table 1. Principal Radiation Emission Data Radiation Mean %/Disintegration Mean Energy (keV) Gamma-2 89.07 140.5 EXTERNAL RADIATION The specific gamma ray constant for technetium Tc99m is 0.795 R/hr-mCi at 1 cm. The first half-value thickness is 0.023 cm of lead (Pb). A range of values for the relative attenuation of the radiation emitted by this radionuclide that results from interposition of various thicknesses of Pb is shown in Table 2. For example, the use of 0.27 cm of Pb will attenuate the radiation emitted by a factor of about 1000. 1 Reference ID: 3803549 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda Table 2. Radiation Attenuation by Lead (Pb) Shielding Shield Thickness (Pb) cm Coefficient of Attenuation 0.023 0.5 0.09 10-1 0.18 10-2 0.27 10-3 0.33 10-4 Molybdenum Mo99 decays to technetium Tc99m with a molybdenum Mo99 half-life of 2.75 days. The physical decay characteristics of molybdenum Mo99 are such that only 86.8% of the decaying molybdenum Mo99 nuclei form technetium Tc99m. Generator elutions may be made at any time, but the amount of technetium Tc99m available will depend on the time interval since the last elution. After six hours approximately 47% of maximum technetium Tc99m is available. Ninety-two percent is reached after 24 hours. To correct for physical decay of each radionuclide, the fractions that remain at selected intervals of time are shown in Tables 3 and 4. Table 3.

For current labeling information, please visit https://www.fda.gov/drugsatfda CLINICAL PHARMACOLOGY The pertechnetate ion distributes in the body similarly to the iodide ion, but is not organified when trapped in the thyroid gland. It also concentrates in the thyroid gland, salivary glands, gastric mucosa, and choroid plexus. However, in contrast to the iodide ion, the pertechnetate ion is released unchanged from the thyroid gland. After intravascular administration, the pertechnetate ion gradually equilibrates with the extracellular space. A fraction is promptly excreted via the kidneys. Following the administration of Sodium Pertechnetate Tc99m Injection as an eye drop, the drug mixes with tears within the conjunctival space. Within seconds to minutes it leaves the conjunctival space and escapes into the inferior meatus of the nose through the nasolacrimal drainage system. During this process the pertechnetate ion passes through the canaliculi, the lacrimal sac and the nasolacrimal duct. In the event of any anatomical or functional blockage of the drainage system there will be a backflow resulting in tearing (epiphora). Thus, the pertechnetate escapes the conjunctival space in the tears. While the major part of the pertechnetate escapes within a few minutes of normal drainage and tearing, it has been documented that there is some degree of transconjunctival absorption with a fractional turnover rate of 0.015/min. in normal individuals, 0.021/min. in patients without any sac, and 0.027/min. in patients with inflamed conjunctiva due to chronic dacryocystitis. Individual values may vary, but these rates are probably representative and indicate that the maximum possible pertechnetate absorbed will remain below one thousandth of that used in other routine diagnostic procedures. INDICATIONS AND USAGE The Drytec (Technetium Tc99m Generator) is a source of sodium pertechnetate Tc99m for use in the preparation of FDA-approved diagnostic radiopharmaceuticals, as described in the labeling of these diagnostic radiopharmaceutical kits. Sodium Pertechnetate Tc99m Injection is used IN ADULTS as an agent for: Thyroid Imaging Salivary Gland Imaging Urinary Bladder Imaging (direct isotopic cystography) for detection of vesico-ureteral reflux Nasolacrimal Drainage System Imaging (dacryoscintigraphy) Sodium Pertechnetate Tc99m Injection is used IN PEDIATRIC PATIENTS as an agent for: Thyroid Imaging Urinary Bladder Imaging (direct isotopic cystography) for the detection of vesico-ureteral reflux CONTRAINDICATIONS None known. 3 Reference ID: 3803549 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda WARNINGS Radiation risks associated with the use of Sodium Pertechnetate Tc99m Injection are greater in pediatric patients than in adults. In general, the younger the patient, the greater the risk owing to greater absorbed radiation doses and longer life expectancy. These greater risks should be taken firmly into account in all benefit-risk assessments involving pediatric patients. Long-term cumulative radiation exposure is associated with increased risk of cancer. PRECAUTIONS General Drytec generators received in advance of the calibration date and time will contain higher amounts of radioactive material. Care should be taken to assure that the generator is properly shielded. As in the use of any radioactive material, care should be taken to minimize radiation exposure to the patient consistent with proper patient management and to insure minimum radiation exposure to occupational workers. After the termination of the nasolacrimal imaging procedure, blowing the nose and washing the eyes with sterile distilled water or an isotonic sodium chloride solution will further minimize the radiation dose. Radiopharmaceuticals should be used only by physicians who are qualified by training and experience in the safe use and handling of radionuclides, and whose experience and training have been approved by the appropriate government agency authorized to license the use of radionuclides. Since the eluate does not contain an antimicrobial agent, it should not be used after twelve hours from the time of generator elution. Carcinogenesis, Mutagenesis, Impairment of Fertility No long-term animal studies have been performed to evaluate carcinogenic potential, mutagenic potential, or whether technetium Tc99m may affect fertility in males or females. Pregnancy Category C Animal reproductive studies have not been conducted with technetium Tc99m. It is also not known whether technetium Tc99m can cause fetal harm when administered to a pregnant woman or can affect reproductive capacity. Technetium Tc99m should be given to pregnant women only if the expected benefits to be gained clearly outweigh the potential hazards. Ideally, examinations using radiopharmaceuticals, especially those elective in nature, of a woman of childbearing capability should be performed during the first few (approximately 10) days following the onset of menses. Nursing Mothers Technetium Tc99m is excreted in human milk during lactation, and therefore formula feedings should be substituted for breast feedings. 4 Reference ID: 3803549 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda Pediatric Use See INDICATIONS AND USAGE, DOSAGE AND ADMINISTRATION. See also description of additional risk under WARNINGS. ADVERSE REACTIONS Allergic reactions including anaphylaxis have been reported infrequently following the administration of sodium pertechnetate Tc99m. DOSAGE AND ADMINISTRATION Sodium Pertechnetate Tc99m Injection is usually administered by intravascular injection. For imaging the urinary bladder and ureters (direct isotopic cystography), the Sodium Pertechnetate Tc99m Injection is instilled aseptically into the bladder via a urethral catheter, following which the catheter is flushed with approximately 200 mL of sterile saline directly into the bladder. The dosage employed varies with each diagnostic procedure. When imaging the nasolacrimal drainage system, instill the Sodium Pertechnetate Tc99m Injection by the use of a device such as a micropipette or similar method which will ensure the accuracy of the dose. The suggested dose ranges employed for various diagnostic indications in average ADULT patients (70 kg) are: Indication Megabecquerels (MBq) Millicuries (mCi) Vesico-ureteral imaging 18.5 - 37 0.5 - 1 Thyroid gland imaging 37 - 370 1 - 10 Salivary gland imaging 37 - 185 1 - 5 Nasolacrimal drainage system imaging 3.70 (max.) 0.100 (max.) The recommended dosage ranges in PEDIATRIC PATIENTS are: Vesico-ureteral imaging 18.5 - 37 MBq (0.5 - 1 mCi) Thyroid gland imaging 2.2 - 2.96 MBq (60 - 80 µCi) per kg body weight. The patient dose should be measured by a suitable radioactivity calibration system immediately prior to administration. Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration whenever solution and container permit. The solution to be administered as the patient dose should be crystal clear and contain no particulate matter. RADIATION DOSIMETRY The estimated absorbed radiation doses to an average ADULT and PEDIATRIC patient from an intravenous injection of a maximum dose of 1110 MBq (30 mCi) of Sodium Pertechnetate Tc99m Injection distributed uniformly in the total body are shown in Tables 5 and 6. 5 Reference ID: 3803549 This label may not be the latest approved by FDA.

For current labeling information, please visit https://www.fda.gov/drugsatfda Instructions for elution of the Drytec (Technetium Tc99m Generator) Elution instructions The facilities used for elutions should comply with the appropriate regulations for safe radiological handling. Strict aseptic techniques should be used during the elution of the generator to ensure sterility of the generator eluate. To avoid unsatisfactory performance it is important to adhere to the following sequence of elution steps. FIRST ELUTION (1) Remove the generator and accompanying accessories from their packaging. Place the generator on a flat, level surface, in a suitably authorized and shielded location. Do not remove the spike and needle protectors until you are ready to carry out the first elution. (2) Select a saline vial containing the required volume of saline. (3) Remove the flip-top from the saline vial and swab the saline vial closure using a bactericidal swab and allow to dry. (4) Remove the spike protector. (5) Place the saline vial onto the spike, ensuring that it is fully pushed to the bottom of the inlet well. Partial rotation will assist the positioning of the vial. (6) Select an evacuated collection vial, remove the flip top cap, and swab the collection vial closure using a bactericidal swab and allow to dry. Prior to placing the collection vial inside the collection vial shield, remove the shield lid and ensure that the vial contact surfaces of the shield have been swabbed using the bactericidal swab provided. Replace the collection vial shield screw-locked cap. The collection shield push- fit top is not required until the elution has been completed. (7) Remove the collection point protector by turning it counter-clockwise. Ensure that the luer type filter attached to the collection point protector is also removed. Retain the collection point protector for use when returning the generator. Immediately fit a collection needle provided in the accessory pack. Do not remove the collection needle sheath until you are ready to place the collection vial on the needle. (8) Remove the collection needle sheath and place the collection vial shield on to the collection needle, aligning the side location into its guide, and the window to the front. Push down to ensure that the vial is fully located on the collection needle. (9) Allow at least 3 minutes for the elution to complete. Elution is complete when all vigorous bubbling has ceased inside the collection vial. Do not remove either the saline vial or collection vial until after elution is complete. (10) Slowly remove the collection vial shield to prevent damage to the collection needle and replace the push-fit top for added radiation protection. (11) Cover with a new collection needle protector from the accessory pack to preserve sterility. (12) To preserve sterility leave the empty saline vial in place until the next elution. 11 Reference ID: 3803549 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda SUBSEQUENT ELUTIONS Using a new sanitized saline vial of the required volume repeat steps 5–12. If the collection needle needs to be changed, remove the damaged needle and swab the collection well to ensure sterility is maintained and fit a new needle. Place a collection needle protector over the new needle. Following expiry, a spare spike protector and the retained collection point protector should be used to cover the spike and collection point respectively. ELUTION VOLUME AND YIELD OF TECHNETIUM Tc99m Due to the elution characteristics of the different column designs, the recommended minimum elution volume for lead shielded generators is 5 mL (2.5 to 30 GBq Mo99). For depleted uranium shielded generators (40 to 100 GBq Mo99) the recommended minimum elution volume is 10 mL. If 5 mL elutions are used a higher radioactive concentration will be obtained, but a small yield reduction is likely. The Drytec Technetium Tc99m Generator is calibrated in terms of the amount of molybdenum Mo99 loaded on the column. The available technetium Tc99m at any time depends on the time before or after reference (due to the decay of molybdenum Mo99, the time elapsed since the previous elution (due to “growth” of technetium Tc99m) and on the decay characteristics of molybdenum Mo99 (86.8% of all decay yields technetium Tc99m). The percentages listed in Tables 9 and 10 may be used to calculate the available technetium Tc99m activity using the following method. First, multiply the stated reference activity by the appropriate factor from Table 9 (which allows for decay of molybdenum Mo99). Then multiply the product by the appropriate percentage from Table 10 (which allows for the growth of technetium Tc99m and for decay characteristics of molybdenum Mo99). The actual yield of technetium Tc99m will vary slightly due to variation in elution efficiency from generator to generator.

The manufacturer’s instructions for operation of the dose calibrator should be followed for measurement of technetium Tc99m and molybdenum Mo99 activity in the generator eluate. The molybdenum Mo99 / technetium Tc99m ratio should be determined at the time of elution prior to administration, and from that ratio, the expiration time (up to 12 hours) of the eluate mathematically determined. Each eluate should meet or exceed the purity requirements of the current United States Pharmacopeia; that is, not more than 0.0056 MBq (0.15 µCi) of molybdenum Mo99 per 37 MBq (1 mCi) of technetium Tc99m per administered dose at the time of administration. RADIOMETRIC MOLYBDENUM TEST PROCEDURE This method is based on the fact that most technetium Tc99m radiation can be readily shielded and only the more energetic gamma rays from molybdenum Mo99 (739KeV and 778KeV) are counted in the 550-850KeV energy range. The entire Sodium Pertechnetate Tc99m Injection eluate may be assayed for molybdenum Mo99 activity as follows: 1. A cesium Cs137 reference source which has the same geometry as the generator eluate must be used to standardize the well counter. 2. Determine the background after setting the window to the 550-850KeV energy range. 3. Count the technetium Tc99m eluate in its lead shield (thereby shielding out technetium Tc99m) by placing over the well or probe. 4. Count the cesium Cs137 reference source in the same shield geometry for the same time period. 5. Compute molybdenum Mo99 activity in the Sodium Pertechnetate Tc99m Injection eluate as follows: μCi molybdenum = μCi simulated Mo99 x net cpm Eluate Mo99 (total) net cpm simulated Mo99 reference source 14 Reference ID: 3803549 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda Divide this number by the mCi of technetium Tc99m. This result (μCi Mo99/mCi Tc99m) can be converted to MBq Mo99/MBq Tc99m by multiplying by 10-3. The U.S. Pharmacopeia and the U.S. Nuclear Regulatory Commission or equivalent Agreement State regulations specify a limit of 0.0056 MBq of molybdenum Mo99 per 37 MBq of technetium Tc99m (0.15 μCi of Mo99 / mCi of Tc99m) at the time of administration to each patient. MOLYBDENUM Mo99 BREAKTHROUGH TEST 1. Determine the amount of technetium Tc99m eluted (MBq, mCi). 2. Place the Sodium Pertechnetate Tc99m Injection eluate in a lead container. Place lid on container and put the entire container in the chamber. 3. Record the amount of molybdenum Mo99 (MBq, mCi) on the most sensitive scale. 4. Divide the MBq, mCi molybdenum Mo99 by the MBq, mCi technetium Tc99m. Correct for decay and shielding effect, if necessary. The molybdenum Mo99/technetium Tc99m ratio should be determined at the time of elution prior to administration, and from that ratio, the expiration time (up to twelve hours) of the eluate mathematically determined. Each Sodium Pertechnetate Tc99m Injection eluate should meet or exceed purity requirement of the current official United States Pharmacopeia. COLORIMETRIC ALUMINIUM TEST PROCEDURE Obtain an aluminium ion indicator kit and determine the aluminium ion concentration of the Sodium Pertechnetate Tc99m Injection eluate per the manufacturer’s instructions. The concentration must not exceed 10 µg/mL of eluate. DISPOSAL: All components shipped with the Drytec (Technetium Tc99m Generator) should be monitored for contamination prior to disposing into routine trash systems. The technetium Tc99m should not be disposed of into routine trash systems. The generator should be disposed through a USNRC or Agreement State licensed disposal agency or by a method approved by the appropriate regulatory authority. Spent generators may be returned; full return instructions of generators to GE Healthcare are provided separately and are available upon request. EXPIRATION DATE The expiry date for the generator is 24 days from the date of manufacture. The reference and expiry dates are stated on the generator label. The Drytec (Technetium Tc99m Generator) should not be used after expiration date. For multidose use, the Sodium Pertechnetate Tc99m Injection eluate should be used within twelve (12) hours of the generator elution time. If the eluate is used to reconstitute a kit, the radio-labeled kit should not be used after twelve (12) hours from the time of generator elution or six (6) hours after reconstitution of the kit, whichever is earlier. The shelf-life for the sodium chloride eluent is 3 years. Since the Sodium Pertechnetate Tc99m Injection eluate does not contain an antimicrobial agent, it should not be used after twelve hours from the time of generator elution. 15 Reference ID: 3803549 This label may not be the latest approved by FDA.

s truc tur al formula NDA 17-760/S-017 Page 3 FML® (fluorometholone ophthalmic ointment) 0.1% sterile DESCRIPTION FML® (fluorometholone ophthalmic ointment) 0.1 % is a sterile, topical anti-inflammatory agent for ophthalmic use. Chemical Name Fluorometholone: 9-Fluoro-11β, 17-dihydroxy-6α-methylpregna-1,4-diene-3,20-dione Structural Formula: Contains Active: fluorometholone 0.1%. Preservative: phenylmercuric acetate (0.0008%). Inactives: mineral oil; petrolatum (and) lanolin alcohol; and white petrolatum. CLINICAL PHARMACOLOGY Corticosteroids inhibit the inflammatory response to a variety of inciting agents and probably delay or slow healing. They inhibit the edema, fibrin deposition, capillary dilation, leukocyte migration, capillary proliferation, fibroblast proliferation, deposition of collagen, and scar formation associated with inflammation. There is no generally accepted explanation for the mechanism of action of ocular corticosteroids. However, corticosteroids are thought to act by the induction of phospholipase A2 inhibitory proteins, collectively called lipocortins. It is postulated that these proteins control the biosynthesis of potent mediators of inflammation such as prostaglandins and leukotrienes by inhibiting the release of their common precursor, arachidonic acid. Arachidonic acid is released from membrane phospholipids by phospholipase A2. Corticosteroids are capable of producing a rise in intraocular pressure. In clinical studies of documented steroid-responders, fluorometholone demonstrated a significantly longer average time to produce a rise in intraocular pressure than dexamethasone phosphate; however, in a small percentage of individuals, a significant rise in intraocular pressure occurred within one week. The ultimate magnitude of the rise was equivalent for both drugs. Reference ID: 3258815 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda NDA 17-760/S-017 Page 4 INDICATIONS AND USAGE FML® ointment is indicated for the treatment of corticosteroid-responsive inflammation of the palpebral and bulbar conjunctiva, cornea and anterior segment of the globe. CONTRAINDICATIONS FML® ointment is contraindicated in most viral diseases of the cornea and conjunctiva, including epithelial herpes simplex keratitis (dendritic keratitis), vaccinia, and varicella, and also in mycobacterial infection of the eye and fungal diseases of ocular structures. FML® ointment is also contraindicated in individuals with known or suspected hypersensitivity to any of the ingredients of this preparation and to other corticosteroids. WARNINGS Prolonged use of corticosteroids may increase intraocular pressure in susceptible individuals, resulting in glaucoma with damage to the optic nerve, defects in visual acuity and fields of vision, and in posterior subcapsular cataract formation. Prolonged use may also suppress the host immune response and thus increase the hazard of secondary ocular infections. Various ocular diseases and long-term use of topical corticosteroids have been known to cause corneal and scleral thinning. Use of topical corticosteroids in the presence of thin corneal or scleral tissue may lead to perforation. Acute purulent infections of the eye may be masked or activity enhanced by the presence of corticosteroid medication. If this product is used for 10 days or longer, intraocular pressure should be routinely monitored even though it may be difficult in children and uncooperative patients. Steroids should be used with caution in the presence of glaucoma. Intraocular pressure should be checked frequently. The use of steroids after cataract surgery may delay healing and increase the incidence of bleb formation. Use of ocular steroids may prolong the course and may exacerbate the severity of many viral infections of the eye (including herpes simplex). Employment of a corticosteroid medication in the treatment of patients with a history of herpes simplex requires great caution; frequent slit lamp microscopy is recommended. PRECAUTIONS General The initial prescription and renewal of the medication order beyond 8 grams of FML® ointment should be made by a physician only after examination of the patient with the aid of magnification, such as slit lamp biomicroscopy, and, where appropriate, fluorescein staining. If signs and symptoms fail to improve after two days, the patient should be re-evaluated. Reference ID: 3258815 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda NDA 17-760/S-017 Page 5 As fungal infections of the cornea are particularly prone to develop coincidentally with long- term local corticosteroid applications, fungal invasion should be suspected in any persistent corneal ulceration where a corticosteroid has been used or is in use. Fungal cultures should be taken when appropriate. If this product is used for 10 days or longer, intraocular pressure should be monitored (see WARNINGS). Ophthalmic ointments may retard corneal healing. Information for Patients If inflammation or pain persists longer than 48 hours or becomes aggravated, the patient should be advised to discontinue use of the medication and consult a physician. This product is sterile when packaged. To prevent contamination, care should be taken to avoid touching the tube tip to eyelids or to any other surface. The use of this tube by more than one person may spread infection. Keep tube tightly closed when not in use. Keep out of the reach of children. Carcinogenesis, Mutagenesis, Impairment of Fertility No studies have been conducted in animals or in humans to evaluate the possibility of these effects with fluorometholone. Pregnancy Teratogenic effects. Pregnancy Category C Fluorometholone has been shown to be embryocidal and teratogenic in rabbits when administered at low multiples of the human ocular dose. Fluorometholone was applied ocularly to rabbits daily on days 6 - 18 of gestation, and dose-related fetal loss and fetal abnormalities including cleft palate, deformed rib cage, anomalous limbs and neural abnormalities such as encephalocele, craniorachischisis, and spina bifida were observed. There are no adequate and well-controlled studies of fluorometholone in pregnant women, and it is not known whether fluorometholone can cause fetal harm when administered to a pregnant woman. Fluorometholone should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus. Nursing Mothers It is not known whether topical ophthalmic administration of corticosteroids could result in sufficient systemic absorption to produce detectable quantities in human milk. Systemically administered corticosteroids appear in human milk and could suppress growth, interfere with endogenous corticosteroid production, or cause other untoward effects. Because of the potential for serious adverse reactions in nursing infants from fluorometholone, a decision should be made whether to discontinue nursing or to discontinue the drug, taking into account the importance of the drug to the mother. Reference ID: 3258815 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda NDA 17-760/S-017 Page 6 Pediatric Use: Safety and effectiveness in infants below the age of two years have not been established. Geriatric use: No overall differences in safety or effectiveness have been observed between elderly and younger patients. ADVERSE REACTIONS Adverse reactions include, in decreasing order of frequency, elevation of intraocular pressure (IOP) with possible development of glaucoma and infrequent optic nerve damage, posterior subcapsular cataract formation, and delayed wound healing. Although systemic effects are extremely uncommon, there have been rare occurrences of systemic hypercorticoidism after use of topical dermatologic steroids applied to the skin. Corticosteroid-containing preparations have also been reported to cause acute anterior uveitis and perforation of the globe. Keratitis, conjunctivitis, corneal ulcers, mydriasis, conjunctival hyperemia, loss of accommodation and ptosis have occasionally been reported following local use of corticosteroids. The development of secondary ocular infection (bacterial, fungal, and viral) has occurred. Fungal and viral infections of the cornea are particularly prone to develop coincidentally with long-term applications of steroids. The possibility of fungal invasion should be considered in any persistent corneal ulceration where steroid treatment has been used (see WARNINGS). Other adverse events reported with the use of fluorometholone include: allergic reactions; foreign body sensation; erythema of eyelid; eyelid edema/eye swelling; eye discharge; eye pain; eye pruritus; lacrimation increased; ocular irritation; rash; taste perversion; visual disturbance (blurry vision); and visual field defect. DOSAGE AND ADMINISTRATION A small amount (approximately 1/2 inch ribbon) of ointment should be applied to the conjunctival sac one to three times daily. During the initial 24 to 48 hours, the dosing frequency may be increased to one application every four hours. Care should be taken not to discontinue therapy prematurely. If signs and symptoms fail to improve after two days, the patient should be re-evaluated (see PRECAUTIONS). The dosing of FML® ointment may be reduced, but care should be taken not to discontinue therapy prematurely. In chronic conditions, withdrawal of treatment should be carried out by gradually decreasing the frequency of applications.

For current labeling information, please visit https://www.fda.gov/drugsatfda NDA 17-766/S-029 Page 6 extent to which essential amino acids and calories promote incorporation of waste urea nitrogen into newly synthesized amino acids in man, as it does in experimental animals, is, so far, not established. The accelerated decrease in serum creatinine levels seen in patients with limited extra-renal complications suggests that treatment with NephrAmine and hypertonic dextrose leads to earlier return of renal function in patients with potentially reversible acute renal failure. By providing nutritional support and promoting biochemical improvement as well as earlier return of renal function, NephrAmine and hypertonic dextrose decrease morbidity associated with acute renal failure. It is thought that acetate from Iysine acetate, under the condition of parenteral nutrition, does not impact net acid-base balance when renal and respiratory functions are normal. Clinical evidence seems to support this thinking; however, confirmatory experimental evidence is not available. The amounts of sodium and chloride present are not of clinical significance. INDICATIONS AND USAGE 5.4% NephrAmine® (Essential Amino Acid Injection) is indicated for adult and pediatric use, in conjunction with other measures, to provide nutritional support for uremic patients, particularly when oral nutrition is infeasible or impractical. See WARNINGS, PRECAUTIONS, Pediatric Use, Special Precautions in Pediatric Patients, and DOSAGE AND ADMINISTRATION. CONTRAINDICATIONS NephrAmine is contraindicated in patients with severe, uncorrected electrolyte and acid-base imbalance, hyperammonemia, decreased (subcritical) circulating blood volume, inborn errors of amino acid metabolism, or hypersensitivity to one or more amino acids present in the solution. WARNINGS WARNING: This product contains aluminum that may be toxic. Aluminum may reach toxic levels with prolonged parenteral administration if kidney function is impaired. Premature neonates are particularly at risk because their kidneys are immature, and they require large amounts of calcium and phosphate solutions, which contain aluminum. Research indicates that patients with impaired kidney function, including premature neonates, who receive parenteral levels of aluminum at greater than 4 to 5 µg/kg/day accumulate aluminum at levels associated with central nervous system and bone toxicity. Tissue loading may occur at even lower rates of administration. This product contains sodium bisulfite, a sulfite that may cause allergic-type reactions including anaphylactic symptoms and life-threatening or less severe asthmatic episodes in certain susceptible people. The overall prevalence of sulfite sensitivity in the general population is unknown and probably low. Sulfite sensitivity is seen more frequently in asthmatic than in nonasthmatic people. Safe and effective use of central venous nutrition requires a knowledge of nutrition as well as clinical expertise in recognition and treatment of the complications which can occur. Frequent clinical evaluation and laboratory determinations are necessary for proper monitoring of central venous nutrition. Laboratory tests should include measurement of blood sugar, electrolyte, and serum protein concentrations; kidney and liver function tests; and evaluation of This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda NDA 17-766/S-029 Page 7 acid-base balance and fluid balance. Other laboratory tests may be suggested by the patient’s condition. NephrAmine does not replace dialysis and conventional supportive therapy in patients with renal failure. Administration of NephrAmine to pediatric patients, especially in high dose ranges, may result in hyperammonemia. Administration of NephrAmine to infants, particularly neonates and low birth weight infants, may result in elevated plasma amino acid levels (e.g., hypermethionemia) and hyperammonemia. In these very young age groups, amino acid formulations developed specifically for nutritional support of infants and pediatric patients, should be considered. Clinically significant hypokalemia, hypophosphatemia, or hypomagnesemia may occur as a result of therapy with NephrAmine and hypertonic dextrose and replacement therapy may become necessary. Administration of nitrogen in any form to patients with marked hepatic insufficiency or hepatic coma may result in plasma amino acid imbalances, hyperammonemia, or central nervous system deterioration. NephrAmine should, therefore, be used with caution in such patients. The intravenous administration of these solutions can cause fluid and/or solute overload resulting in dilution of serum electrolyte concentrations, overhydration, congested states or pulmonary edema. The risk of dilutional states is inversely proportional to the solute concentration of the solution infused. The risk of solute overload causing congested states with peripheral and pulmonary edema is directly proportional to the concentration of the solution. Conservative doses of amino acids should be given, dictated by the nutritional status of the patient. PRECAUTIONS General Clinical evaluation and periodic laboratory determinations are necessary to monitor changes in fluid balance, electrolyte concentrations, and acid-base balance during prolonged parenteral therapy or whenever the condition of the patient warrants such evaluation. Significant deviations from normal concentrations may require the use of additional electrolyte supplements. In order to promote urea nitrogen reutilization in patients with renal failure, it is essential to provide adequate calories with minimal amounts of the essential amino acids, and to severely restrict the intake of nonessential nitrogen. Hypertonic dextrose solutions are a convenient and metabolically effective source of concentrated calories. Fluid balance must be carefully monitored in patients with renal failure and care should be taken to avoid circulatory overload, particularly in association with cardiac insufficiency. In patients with myocardial infarct, infusion of amino acids should always be accompanied by dextrose, since in anoxia, free fatty acids cannot be utilized by the myocardium, and energy must be produced anaerobically from glycogen or glucose. Strongly hypertonic nutrient solutions should be administered through an indwelling intravenous catheter with the tip located in the superior vena cava. Special care must be taken when giving hypertonic dextrose to glucose-intolerant patients such as diabetic or prediabetic and uremic patients, especially when the latter are receiving peritoneal dialysis. To prevent severe hyperglycemia in such patients, insulin may be required. Administration of glucose at a rate exceeding the patient’s utilization may lead to hyperglycemia, coma, and death. This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda NDA 17-766/S-029 Page 8 Administration of amino acids without carbohydrates may result in the accumulation of ketone bodies in the blood. Correction of this ketonemia may be achieved by the administration of carbohydrates. Abrupt cessation of hypertonic dextrose infusion may result in rebound hypoglycemia. When 5.4% NephrAmine® (Essential Amino Acid Injection) is subjected to changes in temperature, there is a chance that some transient crystallization of amino acids may occur. Thorough shaking of the bottle for about one minute should redissolve the amino acids. If the amino acids do not completely redissolve, the bottle must be rejected. To minimize the risk of possible incompatibilities arising from mixing this solution with other additives that may be prescribed, the final infusate should be inspected for cloudiness or precipitation immediately after mixing, prior to administration, and periodically during administration. Use only if solution is clear and vacuum is present. Drug product contains no more than 25 µg/L of aluminum. Laboratory Tests Frequent clinical evaluation and laboratory determinations are necessary for proper monitoring during administration. Laboratory tests should include measurement of blood sugar, electrolyte, and serum protein concentrations; kidney and liver function tests; and evaluation of acid-base balance and fluid balance. Other laboratory tests may be suggested by the patient’s condition. Drug Interactions Some additives may be incompatible. Consult with pharmacist. When introducing additives, use aseptic techniques. Mix thoroughly. Do not store. Carcinogenesis, Mutagenesis, Impairment of Fertility No in vitro or in vivo carcinogenesis, mutagenesis, or fertility studies have been conducted with 5.4% NephrAmine® (Essential Amino Acid Injection). Pregnancy - Teratogenic Effects - Pregnancy Category C. Animal reproduction studies have not been conducted with 5.4% NephrAmine (Essential Amino Acid Injection). It is also not known whether NephrAmine can cause fetal harm when administered to a pregnant woman or can affect reproduction capacity. NephrAmine should be given to a pregnant woman only if clearly needed. Labor and Delivery Information is unknown. Nursing Mothers It is not known whether this drug is excreted in human milk. Because many drugs are excreted in human milk, caution should be exercised when NephrAmine is administered to a nursing woman. This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda NDA 17-766/S-029 Page 9 Pediatric Use Safety and effectiveness of amino acid injections in pediatric patients have not been established by adequate and well-controlled studies. However, the use of amino acid injections in pediatric patients as an adjunct in the offsetting of nitrogen loss or in the treatment of negative nitrogen balance is well established in the medical literature. See INDICATIONS AND USAGE, WARNINGS, and DOSAGE AND ADMINISTRATION. Geriatric Use NephrAmine has not been studied in geriatric patients. Elderly patients are known to be more prone to fluid overload and electrolyte imbalance than younger patients. This may be related to impairment of renal function which is more frequent in an elderly population. As a result the need for careful monitoring of fluid and electrolyte therapy is greater in the elderly. All patients, including the elderly, require an individual dose of all parenteral nutrition products to be determined by the physician on an individual case-by-case basis, which will be based on body weight, clinical condition and the results of laboratory monitoring tests. There is no specific geriatric dose. See WARNINGS. Special Precautions for Central Venous Nutrition Administration by central venous catheter should be used only by those familiar with this technique and its complications. Central venous nutrition may be associated with complications which can be prevented or minimized by careful attention to all aspects of the procedure including solution preparation, administration, and patient monitoring. It is essential that a carefully prepared protocol, based on current medical practices, be followed, preferably by an experienced team. Although a detailed discussion of the complications of central venous nutrition is beyond the scope of this insert, the following summary lists those based on current literature: Technical. The placement of a central venous catheter should be regarded as a surgical procedure. One should be fully acquainted with various techniques of catheter insertion as well as recognition and treatment of complications. For details of techniques and placement sites, consult the medical literature. X-ray is the best means of verifying catheter placement. Complications known to occur from the placement of central venous catheters are pneumothorax, hemothorax, hydrothorax, artery puncture and transection, injury to the brachial plexus, malposition of the catheter, formation of arterio-venous fistula, phlebitis, thrombosis, and air and catheter embolus. Septic. The constant risk of sepsis is present during central venous nutrition. Since contaminated solutions and infusion catheters are potential sources of infection, it is imperative that the preparation of parenteral nutrition solutions and the placement and care of catheters be accomplished under controlled aseptic conditions. Parenteral nutrition solutions should ideally be prepared in the hospital pharmacy under a laminar flow hood. The key factor in their preparation is careful aseptic technique to avoid inadvertent touch contamination during mixing of solutions and subsequent admixtures. This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda NDA 17-766/S-029 Page 10 Parenteral nutrition solutions should be used promptly after mixing. Any storage should be under refrigeration for as brief a time as possible. Administration time for a single bottle and set should never exceed 24 hours. Consult the medical literature for a discussion of the management of sepsis during central venous nutrition. In brief, typical management includes replacing the solution being administered with a fresh container and set, and the remaining contents are cultured for bacterial or fungal contamination. If sepsis persists and another source of infection is not identified, the catheter is removed, the proximal tip cultured, and a new catheter reinserted when the fever has subsided. Nonspecific, prophylactic antibiotic treatment is not recommended. Clinical experience indicates that the catheter is likely to be the prime source of infection as opposed to aseptically prepared and properly stored solutions. Metabolic. The following metabolic complications have been reported: metabolic acidosis, hypophosphatemia, alkalosis, hyperglycemia and glycosuria, osmotic diuresis and dehydration, rebound hypoglycemia, elevated liver enzymes, hypo- and hypervitaminosis, electrolyte imbalances, and elevated plasma amino acid levels and hyperammonemia in infants and pediatric patients. Frequent clinical evaluation and laboratory determinations are necessary, especially during the first few days of central venous nutrition, to prevent or minimize these complications. Special Precautions in Patients with Renal Insufficiency Frequent laboratory studies are necessary in patients with renal insufficiency due to underlying metabolic abnormalities. Hyperglycemia, a frequent complication, may not be reflected by glycosuria in renal failure. Blood glucose, therefore, must be determined frequently, often every six hours to guide dosage of dextrose and insulin if required. Serum concentrations of potassium, phosphorus, and magnesium may dramatically decline with successful treatment, individually or together; these substances should be supplemented as required. Special care must be taken to avoid hypokalemia in digitalized patients, or those with cardiac arrhythmias. Special Precautions in Pediatric Patients 5.4% NephrAmine® (Essential Amino Acid Injection) should be used with special caution in pediatric patients, due to limited clinical experience. Laboratory and clinical monitoring of pediatric patients, especially when nutritionally depleted, must be extensive and frequent. Initial total daily dose should be low, and increased slowly. Dosage of NephrAmine above one gram of essential amino acids per kilogram body weight per day is not recommended. For infants, especially neonates and low birth weight infants, amino acid formulations developed specifically for nutritional support of infants and pediatric patients should be considered. If NephrAmine is administered to these very young patients, extra caution in frequent monitoring of plasma amino acid levels and serum ammonia is strongly recommended. Frequent monitoring of blood glucose is required in neonates, low birth-weight, or septic infants as infusion of hypertonic dextrose carries a greater risk of hyperglycemia in such patients. The absence of arginine in NephrAmine may accentuate the risk of hyperammonemia in infants. This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda NDA 17-766/S-029 Page 11 ADVERSE REACTIONS See WARNINGS and Special Precautions for Central Venous Nutrition. Reactions which may occur because of the solution or the technique of administration include febrile response, infection at the site of injection, venous thrombosis, and hypervolemia. Symptoms may result from an excess or deficit of one or more of the ions present in the solution infused, therefore, frequent monitoring of electrolyte levels is essential. Infrequent instances of hyperammonemia have been reported following administration of essential amino acid solutions to patients with massive gastrointestinal hemorrhage, nonuremic infants and pediatric patients or following administration of higher than recommended doses to adult or pediatric patients. Elevated plasma amino acid levels (hypermethionemia) have also been reported in infants especially in higher dosage ranges. Elevated serum ammonia levels, plasma amino acid levels, and clinical symptoms may subside when the infusions are discontinued. Phosphorus deficiency may lead to impaired tissue oxygenation and acute hemolytic anemia. Relative to calcium, excessive phosphorus intake can precipitate hypocalcemia with cramps, tetany, and muscular hyperexcitability. If an adverse reaction does occur, discontinue the infusion, evaluate the patient, institute appropriate therapeutic countermeasures and save the remainder of the fluid for examination if deemed necessary. OVERDOSAGE In the event of a fluid or solute overload during parenteral therapy, reevaluate the patient’s condition and institute appropriate corrective treatment. DOSAGE AND ADMINISTRATION The objective of nutritional management of renal decompensation is the provision of sufficient amino acid and caloric support for protein synthesis without greatly exceeding the renal capacity to excrete metabolic wastes. Three grams of nitrogen per day provided as essential amino acids with adequate calories produce nitrogen equilibrium in many stable patients with chronic uremia. Although nitrogen requirements may be higher in stressed or acutely uremic patients, or those on dialysis, provision of additional nitrogen may not be possible due to fluid intake limits or glucose intolerance. The usual methods of determining individual patient requirements for amino acids such as nitrogen balance or daily body weight are difficult to perform or interpret in the uremic patient. Therefore, dosage is guided by the patient’s fluid intake limits and glucose and nitrogen tolerances, as well as metabolic and clinical response. Rate of rise of blood urea nitrogen generally diminishes with infusion of essential amino acids. However, excessive intake of dietary protein or increased protein catabolism may alter this response. Adult Use Generally, 250 to 500 mL of 5.4% NephrAmine® (Essential Amino Acid Injection), containing approximately 1.6 to 3.2 grams of nitrogen (in 13.4 to 26.8 grams of essential amino acids), are given daily. Adequate calories should be provided simultaneously. Each 250 mL of NephrAmine This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda NDA 17-766/S-029 Page 12 is typically mixed aseptically with 500 mL of 70% dextrose to yield a solution of 1.8% NephrAmine in 47% dextrose. This mixture provides a calorie-to-nitrogen ratio of 744:1. Pediatric Use Initial total daily dose should be low and increased slowly. As the dose is increased, frequent laboratory and clinical monitoring is strongly recommended, especially in very young patients, to avoid clinically significant elevations of serum ammonia and plasma amino acid levels. Dosage of NephrAmine above one gram of essential amino acids per kg of body weight per day is not recommended. In pediatric patients, the final solution should not exceed twice normal serum osmolarity (718 mOsmol/L). Use of 5.4% NephrAmine in pediatric patients is governed by the same considerations that affect the use of any amino acid solution in pediatrics. The amount administered is dosed on the basis of grams of amino acids/kg of body weight/day. Two to three g/kg of body weight for infants with adequate calories are generally sufficient to satisfy protein needs and promote positive nitrogen balance. Solution administrated by peripheral vein should not exceed twice normal serum osmolarity (718 mOsmol/L). See INDICATIONS AND USAGE, WARNINGS, PRECAUTIONS, Pediatric Use, and Special Precautions in Pediatric Patients. Fat emulsion coadministration should be considered when prolonged (more than 5 days) parenteral nutrition is required in order to prevent essential fatty acid deficiency (E.F.A.D.). Serum lipids should be monitored for evidence of E.F.A.D. in patients maintained on fat free TPN. Electrolyte supplementation may be required. Undiluted NephrAmine® (Essential Amino Acid Injection) contains 5 mEq/liter of sodium. Elevated serum potassium, phosphorus, and magnesium levels generally decrease during treatment with NephrAmine. Although these effects are beneficial, especially in acute renal failure, in some instances the reduction may be so great that supplementation of these electrolytes is required, especially in the presence of cardiac arrhythmias or digitalis toxicity. During periods of anuria or oliguria, electrolyte supplementation should be done with caution, even if serum levels are in the low normal range. Compatibility of electrolyte additives to the 5.4% NephrAmine/hypertonic dextrose mixture must be considered, and potentially incompatible ions such as calcium and phosphate may be added to alternate infusion bottles to avoid precipitation. In patients with hyperchloremic or other metabolic acidosis, sodium and potassium may be added as acetate or lactate salts to provide bicarbonate precursor. The electrolyte content of NephrAmine must be considered when calculating daily electrolyte intake. Serum electrolytes, including magnesium and phosphorus, should be monitored frequently. If a patient’s nutritional intake is primarily parenteral, vitamins, especially the water soluble vitamins, should also be provided. Hypertonic mixtures of essential amino acids and dextrose may be safely administered by continuous infusion through a central venous catheter with the tip located in the superior vena cava. Initial infusion rates should be slow, generally 20-30 mL/hour. Increases by increments of 10 mL/hour each 24 hours are recommended to a maximum of 60-100 mL/hour. If administration rate should fall behind schedule, no attempt to “catch up” to planned intake should be made. Administration rate is governed by the patient’s nitrogen, fluid, and glucose tolerance. Uremic patients are frequently glucose intolerant, especially in association with peritoneal dialysis, and This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda NDA 17-766/S-029 Page 13 may require the administration of exogenous insulin to prevent hyperglycemia. Blood glucose levels must be determined frequently. To prevent rebound hypoglycemia, a solution containing 5% dextrose should be administered when hypertonic dextrose infusions are abruptly discontinued. Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration, whenever solution and container permit. Care must be taken to avoid incompatible admixtures. Consult with pharmacist.

Ativan® CIV (lorazepam) Tablets Rx only DESCRIPTION Ativan (lorazepam), an antianxiety agent, has the chemical formula, 7-chloro-5- (o-chlorophenyl)-1,3-dihydro-3-hydroxy-2H-1,4-benzodiazepin-2-one: C15H10Cl2N2O2 MW: 321.16 It is a nearly white powder almost insoluble in water. Each Ativan (lorazepam) tablet, to be taken orally, contains 0.5 mg, 1 mg, or 2 mg of lorazepam. The inactive ingredients present are lactose monohydrate, magnesium stearate, microcrystalline cellulose, polacriline potassium. CLINICAL PHARMACOLOGY Studies in healthy volunteers show that in single high doses Ativan (lorazepam) has a tranquilizing action on the central nervous system with no appreciable effect on the respiratory or cardiovascular systems. Ativan (lorazepam) is readily absorbed with an absolute bioavailability of 90 percent. Peak concentrations in plasma occur approximately 2 hours following administration. The peak plasma level of lorazepam from a 2 mg dose is approximately 20 ng/mL. The mean half-life of unconjugated lorazepam in human plasma is about 12 hours and for its major metabolite, lorazepam glucuronide, about 18 hours. At clinically relevant concentrations, lorazepam is approximately 85% bound to plasma proteins. Ativan (lorazepam) is rapidly conjugated at its 3-hydroxy group into lorazepam glucuronide which is then excreted in the urine. Lorazepam glucuronide has no demonstrable CNS activity in animals. This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda The plasma levels of lorazepam are proportional to the dose given. There is no evidence of accumulation of lorazepam on administration up to six months. Studies comparing young and elderly subjects have shown that advancing age does not have a significant effect on the pharmacokinetics of lorazepam. However, in one study involving single intravenous doses of 1.5 to 3 mg of Ativan Injection, mean total body clearance of lorazepam decreased by 20% in 15 elderly subjects of 60 to 84 years of age compared to that in 15 younger subjects of 19 to 38 years of age. INDICATIONS AND USAGE Ativan (lorazepam) is indicated for the management of anxiety disorders or for the short-term relief of the symptoms of anxiety or anxiety associated with depressive symptoms. Anxiety or tension associated with the stress of everyday life usually does not require treatment with an anxiolytic. The effectiveness of Ativan (lorazepam) in long-term use, that is, more than 4 months, has not been assessed by systematic clinical studies. The physician should periodically reassess the usefulness of the drug for the individual patient. CONTRAINDICATIONS Ativan (lorazepam) is contraindicated in patients with - hypersensitivity to benzodiazepines or to any components of the formulation. - acute narrow-angle glaucoma. WARNINGS Pre-existing depression may emerge or worsen during use of benzodiazepines including lorazepam. Ativan (lorazepam) is not recommended for use in patients with a primary depressive disorder or psychosis. Use of benzodiazepines, including lorazepam, both used alone and in combination with other CNS depressants, may lead to potentially fatal respiratory depression. (See PRECAUTIONS, Clinically Significant Drug Interactions) Use of benzodiazepines, including lorazepam, may lead to physical and psychological dependence. As with all patients on CNS-depressant drugs, patients receiving lorazepam should be warned not to operate dangerous machinery or motor vehicles and that their tolerance for alcohol and other CNS depressants will be diminished. Physical And Psychological Dependence The use of benzodiazepines, including lorazepam, may lead to physical and psychological dependence. The risk of dependence increases with higher doses and longer term use and is further increased in patients with a history of alcoholism or drug abuse or in patients with significant personality disorders. The dependence potential is reduced when lorazepam is used at the appropriate dose for short-term treatment. Addiction-prone individuals (such as drug addicts This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda or alcoholics) should be under careful surveillance when receiving lorazepam or other psychotropic agents. In general, benzodiazepines should be prescribed for short periods only (e.g. 2- 4 weeks). Extension of the treatment period should not take place without reevaluation of the need for continued therapy. Continuous long-term use of product is not recommended. Withdrawal symptoms (e.g. rebound insomnia) can appear following cessation of recommended doses after as little as one week of therapy. Abrupt discontinuation of product should be avoided and a gradual dosage-tapering schedule followed after extended therapy. Abrupt termination of treatment may be accompanied by withdrawal symptoms. Symptoms reported following discontinuation of benzodiazepines include headache, anxiety, tension, depression, insomnia, restlessness, confusion, irritability, sweating, rebound phenomena, dysphoria, dizziness, derealization, depersonalization, hyperacusis, numbness/tingling of extremities, hypersensitivity to light, noise, and physical contact/perceptual changes, involuntary movements, nausea, vomiting, diarrhea, loss of appetite, hallucinations/delirium, convulsions/seizures, tremor, abdominal cramps, myalgia, agitation, palpitations, tachycardia, panic attacks, vertigo, hyperreflexia, short-term memory loss, and hyperthermia. Convulsions/seizures may be more common in patients with pre- existing seizure disorders or who are taking other drugs that lower the convulsive threshold such as antidepressants. There is evidence that tolerance develops to the sedative effects of benzodiazepines. Lorazepam may have abuse potential, especially in patients with a history of drug and/or alcohol abuse. PRECAUTIONS In patients with depression, a possibility for suicide should be borne in mind; benzodiazepines should not be used in such patients without adequate anti- depressant therapy. Lorazepam should be used with caution in patients with compromised respiratory function (e.g. COPD, sleep apnea syndrome). Elderly or debilitated patients may be more susceptible to the sedative effects of lorazepam. Therefore, these patients should be monitored frequently and have their dosage adjusted carefully according to patient response; the initial dosage should not exceed 2 mg. Paradoxical reactions have been occasionally reported during benzodiazepine use. Such reactions may be more likely to occur in children and the elderly. Should these occur, use of the drug should be discontinued. The usual precautions for treating patients with impaired renal and hepatic function should be observed. As with all benzodiazepines, the use of lorazepam may worsen hepatic encephalopathy; therefore, lorazepam should be used with caution in patients with severe hepatic insufficiency and/or encephalopathy. This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda Dosage for patients with severe hepatic insufficiency should be adjusted carefully according to patient response; lower doses may be sufficient in such patients. In patients where gastrointestinal or cardiovascular disorders coexist with anxiety, it should be noted that lorazepam has not been shown to be of significant benefit in treating the gastrointestinal or cardiovascular component. Esophageal dilation occurred in rats treated with lorazepam for more than one year at 6 mg/kg/day. The no-effect dose was 1.25 mg/kg/day (approximately 6 times the maximum human therapeutic dose of 10 mg per day). The effect was reversible only when the treatment was withdrawn within two months of first observation of the phenomenon. The clinical significance of this is unknown. However, use of lorazepam for prolonged periods and in geriatric patients requires caution, and there should be frequent monitoring for symptoms of upper G.I. disease. Safety and effectiveness of Ativan (lorazepam) in children of less than 12 years have not been established. Information For Patients To assure the safe and effective use of Ativan (lorazepam), patients should be informed that, since benzodiazepines may produce psychological and physical dependence, it is advisable that they consult with their physician before either increasing the dose or abruptly discontinuing this drug. Essential Laboratory Tests Some patients on Ativan (lorazepam) have developed leukopenia, and some have had elevations of LDH. As with other benzodiazepines, periodic blood counts and liver-function tests are recommended for patients on long-term therapy. Clinically Significant Drug Interactions The benzodiazepines, including Ativan (lorazepam), produce increased CNS- depressant effects when administered with other CNS depressants such as alcohol, barbiturates, antipsychotics, sedative/hypnotics, anxiolytics, antidepressants, narcotic analgesics, sedative antihistamines, anticonvulsants, and anesthetics. Concomitant use of clozapine and lorazepam may produce marked sedation, excessive salivation, hypotension, ataxia, delirium, and respiratory arrest. Concurrent administration of lorazepam with valproate results in increased plasma concentrations and reduced clearance of lorazepam. Lorazepam dosage should be reduced to approximately 50% when coadministered with valproate. Concurrent administration of lorazepam with probenecid may result in a more rapid onset or prolonged effect of lorazepam due to increased half-life and decreased total clearance. Lorazepam dosage needs to be reduced by approximately 50% when coadministered with probenecid. The effects of probenecid and valproate on lorazepam may be due to inhibition of glucuronidation. This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda Administration of theophylline or aminophylline may reduce the sedative effects of benzodiazepines, including lorazepam. Carcinogenesis And Mutagenesis No evidence of carcinogenic potential emerged in rats during an 18-month study with Ativan (lorazepam). No studies regarding mutagenesis have been performed. Pregnancy Reproductive studies in animals were performed in mice, rats, and two strains of rabbits. Occasional anomalies (reduction of tarsals, tibia, metatarsals, malrotated limbs, gastroschisis, malformed skull, and microphthalmia) were seen in drug- treated rabbits without relationship to dosage. Although all of these anomalies were not present in the concurrent control group, they have been reported to occur randomly in historical controls. At doses of 40 mg/kg and higher, there was evidence of fetal resorption and increased fetal loss in rabbits which was not seen at lower doses. The clinical significance of the above findings is not known. However, an increased risk of congenital malformations associated with the use of minor tranquilizers (chlordiazepoxide, diazepam, and meprobamate) during the first trimester of pregnancy has been suggested in several studies. Because the use of these drugs is rarely a matter of urgency, the use of lorazepam during this period should be avoided. The possibility that a woman of childbearing potential may be pregnant at the time of institution of therapy should be considered. Patients should be advised that if they become pregnant, they should communicate with their physician about the desirability of discontinuing the drug. In humans, blood levels obtained from umbilical cord blood indicate placental transfer of lorazepam and lorazepam glucuronide. Infants of mothers who ingested benzodiazepines for several weeks or more preceding delivery have been reported to have withdrawal symptoms during the postnatal period. Symptoms such as hypoactivity, hypotonia, hypothermia, respiratory depression, apnea, feeding problems, and impaired metabolic response to cold stress have been reported in neonates born of mothers who have received benzodiazepines during the late phase of pregnancy or at delivery. Nursing Mothers Lorazepam has been detected in human breast milk; therefore, it should not be administered to breast-feeding women, unless the expected benefit to the woman outweighs the potential risk to the infant. Sedation and inability to suckle have occurred in neonates of lactating mothers taking benzodiazepines. Infants of lactating mothers should be observed for pharmacological effects (including sedation and irritability). Geriatric Use Clinical studies of Ativan generally were not adequate to determine whether subjects aged 65 and over respond differently than younger subjects; however, This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda the incidence of sedation and unsteadiness was observed to increase with age (see ADVERSE REACTIONS). Age does not appear to have a significant effect on lorazepam kinetics (see CLINICAL PHARMACOLOGY). Clinical circumstances, some of which may be more common in the elderly, such as hepatic or renal impairment, should be considered. Greater sensitivity (e.g., sedation) of some older individuals cannot be ruled out. In general, dose selection for an elderly patient should be cautious, and lower doses may be sufficient in these patients (see DOSAGE AND ADMINISTRATION). ADVERSE REACTIONS Most adverse reactions to benzodiazepines, including CNS effects and respiratory depression, are dose dependent, with more severe effects occurring with high doses. In a sample of about 3500 patients treated for anxiety, the most frequent adverse reaction to Ativan (lorazepam) was sedation (15.9%), followed by dizziness (6.9%), weakness (4.2%), and unsteadiness (3.4%). The incidence of sedation and unsteadiness increased with age. Other adverse reactions to benzodiazepines, including lorazepam are fatigue, drowsiness, amnesia, memory impairment, confusion, disorientation, depression, unmasking of depression, disinhibition, euphoria, suicidal ideation/attempt, ataxia, asthenia, extrapyramidal symptoms, convulsions/seizures tremor, vertigo, eye-function/visual disturbance (including diplopia and blurred vision), dysarthria/slurred speech, change in libido, impotence, decreased orgasm; headache, coma; respiratory depression, apnea, worsening of sleep apnea, worsening of obstructive pulmonary disease; gastrointestinal symptoms including nausea, change in appetite, constipation, jaundice, increase in bilirubin, increase in liver transaminases, increase in alkaline phosphatase; hypersensitivity reactions, anaphylactic/oid reactions; dermatological symptoms, allergic skin reactions, alopecia; SIADH, hyponatremia; thrombocytopenia, agranulocytosis, pancytopenia; hypothermia; and autonomic manifestations. Paradoxical reactions, including anxiety, excitation, agitation, hostility, aggression, rage, sleep disturbances/insomnia, sexual arousal, and hallucinations may occur. Small decreases in blood pressure and hypotension may occur but are usually not clinically significant, probably being related to the relief of anxiety produced by Ativan (lorazepam). OVERDOSAGE In postmarketing experience, overdose with lorazepam has occurred predominantly in combination with alcohol and/or other drugs. Therefore, in the management of overdosage , it should be borne in mind that multiple agents may have been taken. Symptoms This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda Overdosage of benzodiazepines is usually manifested by varying degrees of central nervous system depression ranging from drowsiness to coma. In mild cases, symptoms include drowsiness, mental confusion, paradoxical reactions, dysarthria and lethargy. In more serious cases, and especially when other drugs or alcohol were ingested, symptoms may include ataxia, hypotonia, hypotension, cardiovascular depression, respiratory depression, hypnotic state, coma, and death. MANAGEMENT General supportive and symptomatic measures are recommended; vital signs must be monitored and the patient closely observed. When there is a risk of aspiration, induction of emesis is not recommended. Gastric lavage may be indicated if performed soon after ingestion or in symptomatic patients. Administration of activated charcoal may also limit drug absorption. Hypotension, though unlikely, usually may be controlled with norepinephrine bitartrate injection. Lorazepam is poorly dialyzable. Lorazepam glucuronide, the inactive metabolite, may be highly dialyzable. The benzodiazepine antagonist flumazenil may be used in hospitalized patients as an adjunct to, not as a substitute for, proper management of benzodiazepine overdose. The prescriber should be aware of a risk of seizure in association with flumazenil treatment, particularly in long-term benzodiazepine users and in cyclic antidepressant overdose. The complete flumazenil package insert including CONTRAINDICATIONS, WARNINGS, and PRECAUTIONS should be consulted prior to use. DOSAGE AND ADMINISTRATION Ativan (lorazepam) is administered orally. For optimal results, dose, frequency of administration, and duration of therapy should be individualized according to patient response. To facilitate this, 0.5 mg, 1 mg, and 2 mg tablets are available. The usual range is 2 to 6 mg/day given in divided doses, the largest dose being taken before bedtime, but the daily dosage may vary from 1 to 10 mg/day. For anxiety, most patients require an initial dose of 2 to 3 mg/day given b.i.d. or t.i.d. For insomnia due to anxiety or transient situational stress, a single daily dose of 2 to 4 mg may be given, usually at bedtime. For elderly or debilitated patients, an initial dosage of 1 to 2 mg/day in divided doses is recommended, to be adjusted as needed and tolerated. The dosage of Ativan (lorazepam) should be increased gradually when needed to help avoid adverse effects. When higher dosage is indicated, the evening dose should be increased before the daytime doses.

GLUCOTROL® (glipizide) TABLETS For Oral Use DESCRIPTION GLUCOTROL (glipizide) is an oral blood-glucose-lowering drug of the sulfonylurea class. The Chemical Abstracts name of glipizide is 1-cyclohexyl-3-[[p-[2-(5-methylpyrazine- carboxamido)ethyl]phenyl]sulfonyl]urea. The molecular formula is C21H27N5O4S; the molecular weight is 445.55; the structural formula is shown below: Ch emical Structure of Glucotrol (glipizide) H Glipizide is a whitish, odorless powder with a pKa of 5.9. It is insoluble in water and alcohols, but soluble in 0.1 N NaOH; it is freely soluble in dimethylformamide. GLUCOTROL tablets for oral use are available in 5 and 10 mg strengths. Inert ingredients are: colloidal silicon dioxide; lactose; microcrystalline cellulose; starch; stearic acid. CLINICAL PHARMACOLOGY Mechanism of Action: The primary mode of action of GLUCOTROL in experimental animals appears to be the stimulation of insulin secretion from the beta cells of pancreatic islet tissue and is thus dependent on functioning beta cells in the pancreatic islets. In humans GLUCOTROL appears to lower the blood glucose acutely by stimulating the release of insulin from the pancreas, an effect dependent upon functioning beta cells in the pancreatic islets. The mechanism by which GLUCOTROL lowers blood glucose during long-term administration has not been clearly established. In man, stimulation of insulin secretion by GLUCOTROL in response to a meal is undoubtedly of major importance. Fasting insulin levels are not elevated 1 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda even on long-term GLUCOTROL administration, but the postprandial insulin response continues to be enhanced after at least 6 months of treatment. The insulinotropic response to a meal occurs within 30 minutes after an oral dose of GLUCOTROL in diabetic patients, but elevated insulin levels do not persist beyond the time of the meal challenge. Extrapancreatic effects may play a part in the mechanism of action of oral sulfonylurea hypoglycemic drugs. Blood sugar control persists in some patients for up to 24 hours after a single dose of GLUCOTROL, even though plasma levels have declined to a small fraction of peak levels by that time (see Pharmacokinetics below). Some patients fail to respond initially, or gradually lose their responsiveness to sulfonylurea drugs, including GLUCOTROL. Alternatively, GLUCOTROL may be effective in some patients who have not responded or have ceased to respond to other sulfonylureas. Other Effects: It has been shown that GLUCOTROL therapy was effective in controlling blood sugar without deleterious changes in the plasma lipoprotein profiles of patients treated for NIDDM. In a placebo-controlled, crossover study in normal volunteers, GLUCOTROL had no antidiuretic activity, and, in fact, led to a slight increase in free water clearance. Pharmacokinetics: Gastrointestinal absorption of GLUCOTROL in man is uniform, rapid, and essentially complete. Peak plasma concentrations occur 1–3 hours after a single oral dose. The half-life of elimination ranges from 2–4 hours in normal subjects, whether given intravenously or orally. The metabolic and excretory patterns are similar with the two routes of administration, indicating that first-pass metabolism is not significant. GLUCOTROL does not accumulate in plasma on repeated oral administration. Total absorption and disposition of an oral dose was unaffected by food in normal volunteers, but absorption was delayed by about 40 minutes. Thus GLUCOTROL was more effective when administered about 30 minutes before, rather than with, a test meal in diabetic patients. Protein binding was studied in serum from volunteers who received either oral or intravenous GLUCOTROL and found to be 98–99% one hour after either route of administration. The apparent volume of distribution of GLUCOTROL after intravenous administration was 11 liters, indicative of localization within the extracellular fluid compartment. In mice no GLUCOTROL or metabolites were detectable autoradiographically in the brain or spinal cord of males or females, nor in the fetuses of pregnant females. In another study, however, very small amounts of radioactivity were detected in the fetuses of rats given labelled drug. The metabolism of GLUCOTROL is extensive and occurs mainly in the liver. The primary metabolites are inactive hydroxylation products and polar conjugates and are excreted mainly in the urine. Less than 10% unchanged GLUCOTROL is found in the urine. 2 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda INDICATIONS AND USAGE GLUCOTROL is indicated as an adjunct to diet and exercise to improve glycemic control in adults with type 2 diabetes mellitus. CONTRAINDICATIONS GLUCOTROL is contraindicated in patients with: 1. Known hypersensitivity to the drug. 2. Type 1 diabetes mellitus, diabetic ketoacidosis, with or without coma. This condition should be treated with insulin. WARNINGS SPECIAL WARNING ON INCREASED RISK OF CARDIOVASCULAR MORTALITY: The administration of oral hypoglycemic drugs has been reported to be associated with increased cardiovascular mortality as compared to treatment with diet alone or diet plus insulin. This warning is based on the study conducted by the University Group Diabetes Program (UGDP), a long-term prospective clinical trial designed to evaluate the effectiveness of glucose-lowering drugs in preventing or delaying vascular complications in patients with non-insulin-dependent diabetes. The study involved 823 patients who were randomly assigned to one of four treatment groups (Diabetes, 19, supp. 2: 747–830, 1970). UGDP reported that patients treated for 5 to 8 years with diet plus a fixed dose of tolbutamide (1.5 grams per day) had a rate of cardiovascular mortality approximately 2½ times that of patients treated with diet alone. A significant increase in total mortality was not observed, but the use of tolbutamide was discontinued based on the increase in cardiovascular mortality, thus limiting the opportunity for the study to show an increase in overall mortality. Despite controversy regarding the interpretation of these results, the findings of the UGDP study provide an adequate basis for this warning. The patient should be informed of the potential risks and advantages of GLUCOTROL and of alternative modes of therapy. Although only one drug in the sulfonylurea class (tolbutamide) was included in this study, it is prudent from a safety standpoint to consider that this warning may also apply to other oral hypoglycemic drugs in this class, in view of their close similarities in mode of action and chemical structure. PRECAUTIONS General Macrovascular Outcomes: There have been no clinical studies establishing conclusive evidence of macrovascular risk reduction with GLUCOTROL or any other anti-diabetic drug. 3 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda Renal and Hepatic Disease: The metabolism and excretion of GLUCOTROL may be slowed in patients with impaired renal and/or hepatic function. If hypoglycemia should occur in such patients, it may be prolonged and appropriate management should be instituted. Hypoglycemia: All sulfonylurea drugs are capable of producing severe hypoglycemia. Proper patient selection, dosage, and instructions are important to avoid hypoglycemic episodes. Renal or hepatic insufficiency may cause elevated blood levels of GLUCOTROL and the latter may also diminish gluconeogenic capacity, both of which increase the risk of serious hypoglycemic reactions. Elderly, debilitated or malnourished patients, and those with adrenal or pituitary insufficiency, are particularly susceptible to the hypoglycemic action of glucose-lowering drugs. Hypoglycemia may be difficult to recognize in the elderly, and in people who are taking beta-adrenergic blocking drugs. Hypoglycemia is more likely to occur when caloric intake is deficient, after severe or prolonged exercise, when alcohol is ingested, or when more than one glucose-lowering drug is used. Loss of Control of Blood Glucose: When a patient stabilized on any diabetic regimen is exposed to stress such as fever, trauma, infection, or surgery, a loss of control may occur. At such times, it may be necessary to discontinue GLUCOTROL and administer insulin. The effectiveness of any oral hypoglycemic drug, including GLUCOTROL, in lowering blood glucose to a desired level decreases in many patients over a period of time, which may be due to progression of the severity of the diabetes or to diminished responsiveness to the drug. This phenomenon is known as secondary failure, to distinguish it from primary failure in which the drug is ineffective in an individual patient when first given. Hemolytic Anemia: Treatment of patients with glucose 6-phosphate dehydrogenase (G6PD) deficiency with sulfonylurea agents can lead to hemolytic anemia. Because GLUCOTROL belongs to the class of sulfonylurea agents, caution should be used in patients with G6PD deficiency and a non-sulfonylurea alternative should be considered. In post marketing reports, hemolytic anemia has also been reported in patients who did not have known G6PD deficiency. Laboratory Tests: Blood and urine glucose should be monitored periodically. Measurement of glycosylated hemoglobin may be useful. Information for Patients: Patients should be informed of the potential risks and advantages of GLUCOTROL and of alternative modes of therapy. They should also be informed about the importance of adhering to dietary instructions, of a regular exercise program, and of regular testing of urine and/or blood glucose. The risks of hypoglycemia, its symptoms and treatment, and conditions that predispose to its development should be explained to patients and responsible family members. Primary and secondary failure should also be explained. 4 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda Physician Counseling Information for Patients: In initiating treatment for type 2 diabetes, diet should be emphasized as the primary form of treatment. Caloric restriction and weight loss are essential in the obese diabetic patient. Proper dietary management alone may be effective in controlling the blood glucose and symptoms of hyperglycemia. The importance of regular physical activity should also be stressed, and cardiovascular risk factors should be identified and corrective measures taken where possible. Use of GLUCOTROL or other antidiabetic medications must be viewed by both the physician and patient as a treatment in addition to diet and not as a substitution or as a convenient mechanism for avoiding dietary restraint. Furthermore, loss of blood glucose control on diet alone may be transient, thus requiring only short-term administration of GLUCOTROL or other antidiabetic medications. Maintenance or discontinuation of GLUCOTROL or other antidiabetic medications should be based on clinical judgment using regular clinical and laboratory evaluations. Drug Interactions: The hypoglycemic action of sulfonylureas may be potentiated by certain drugs including nonsteroidal anti-inflammatory agents, some azoles, and other drugs that are highly protein bound, salicylates, sulfonamides, chloramphenicol, probenecid, coumarins, monoamine oxidase inhibitors, and beta adrenergic blocking agents. When such drugs are administered to a patient receiving GLUCOTROL, the patient should be observed closely for hypoglycemia. When such drugs are withdrawn from a patient receiving GLUCOTROL, the patient should be observed closely for loss of control. In vitro binding studies with human serum proteins indicate that GLUCOTROL binds differently than tolbutamide and does not interact with salicylate or dicumarol. However, caution must be exercised in extrapolating these findings to the clinical situation and in the use of GLUCOTROL with these drugs. Certain drugs tend to produce hyperglycemia and may lead to loss of control. These drugs include the thiazides and other diuretics, corticosteroids, phenothiazines, thyroid products, estrogens, oral contraceptives, phenytoin, nicotinic acid, sympathomimetics, calcium channel blocking drugs, and isoniazid. When such drugs are administered to a patient receiving GLUCOTROL, the patient should be closely observed for loss of control. When such drugs are withdrawn from a patient receiving GLUCOTROL, the patient should be observed closely for hypoglycemia. A potential interaction between oral miconazole and oral hypoglycemic agents leading to severe hypoglycemia has been reported. Whether this interaction also occurs with the intravenous, topical, or vaginal preparations of miconazole is not known. The effect of concomitant administration of DIFLUCAN® (fluconazole) and GLUCOTROL has been demonstrated in a placebo-controlled crossover study in normal volunteers. All subjects received GLUCOTROL alone and following treatment with 100 mg of DIFLUCAN as a single daily oral dose for 7 days. 5 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda The mean percentage increase in the GLUCOTROL AUC after fluconazole administration was 56.9% (range: 35 to 81). Carcinogenesis, Mutagenesis, Impairment of Fertility: A twenty month study in rats and an eighteen month study in mice at doses up to 75 times the maximum human dose revealed no evidence of drug-related carcinogenicity. Bacterial and in vivo mutagenicity tests were uniformly negative. Studies in rats of both sexes at doses up to 75 times the human dose showed no effects on fertility. Pregnancy: Pregnancy Category C: GLUCOTROL (glipizide) was found to be mildly fetotoxic in rat reproductive studies at all dose levels (5–50 mg/kg). This fetotoxicity has been similarly noted with other sulfonylureas, such as tolbutamide and tolazamide. The effect is perinatal and believed to be directly related to the pharmacologic (hypoglycemic) action of GLUCOTROL. In studies in rats and rabbits no teratogenic effects were found. There are no adequate and well controlled studies in pregnant women. GLUCOTROL should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus. Because recent information suggests that abnormal blood glucose levels during pregnancy are associated with a higher incidence of congenital abnormalities, many experts recommend that insulin be used during pregnancy to maintain blood glucose levels as close to normal as possible. Nonteratogenic Effects: Prolonged severe hypoglycemia (4 to 10 days) has been reported in neonates born to mothers who were receiving a sulfonylurea drug at the time of delivery. This has been reported more frequently with the use of agents with prolonged half-lives. If GLUCOTROL is used during pregnancy, it should be discontinued at least one month before the expected delivery date. Nursing Mothers: Although it is not known whether GLUCOTROL is excreted in human milk, some sulfonylurea drugs are known to be excreted in human milk. Because the potential for hypoglycemia in nursing infants may exist, a decision should be made whether to discontinue nursing or to discontinue the drug, taking into account the importance of the drug to the mother. If the drug is discontinued and if diet alone is inadequate for controlling blood glucose, insulin therapy should be considered. Pediatric Use: Safety and effectiveness in children have not been established. Geriatric Use: A determination has not been made whether controlled clinical studies of GLUCOTROL included sufficient numbers of subjects aged 65 and over to define a difference in response from younger subjects. Other reported clinical experience has not identified differences in responses between the elderly and younger patients. In general, dose selection for an elderly patient should be cautious, usually starting at the low end of the dosing range, reflecting the greater frequency of decreased hepatic, renal or cardiac function, and of concomitant disease or other drug therapy. ADVERSE REACTIONS 6 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda In U.S. and foreign controlled studies, the frequency of serious adverse reactions reported was very low. Of 702 patients, 11.8% reported adverse reactions and in only 1.5% was GLUCOTROL discontinued. Hypoglycemia: See PRECAUTIONS and OVERDOSAGE sections. Gastrointestinal: Gastrointestinal disturbances are the most common reactions. Gastrointestinal complaints were reported with the following approximate incidence: nausea and diarrhea, one in seventy; constipation and gastralgia, one in one hundred. They appear to be dose-related and may disappear on division or reduction of dosage. Cholestatic jaundice may occur rarely with sulfonylureas: GLUCOTROL should be discontinued if this occurs. Dermatologic: Allergic skin reactions including erythema, morbilliform or maculopapular eruptions, urticaria, pruritus, and eczema have been reported in about one in seventy patients. These may be transient and may disappear despite continued use of GLUCOTROL; if skin reactions persist, the drug should be discontinued. Porphyria cutanea tarda and photosensitivity reactions have been reported with sulfonylureas. Hematologic: Leukopenia, agranulocytosis, thrombocytopenia, hemolytic anemia (see PRECAUTIONS), aplastic anemia, and pancytopenia have been reported with sulfonylureas. Metabolic: Hepatic porphyria and disulfiram-like reactions have been reported with sulfonylureas. In the mouse, GLUCOTROL pretreatment did not cause an accumulation of acetaldehyde after ethanol administration. Clinical experience to date has shown that GLUCOTROL has an extremely low incidence of disulfiram-like alcohol reactions. Endocrine Reactions: Cases of hyponatremia and the syndrome of inappropriate antidiuretic hormone (SIADH) secretion have been reported with this and other sulfonylureas. Miscellaneous: Dizziness, drowsiness, and headache have each been reported in about one in fifty patients treated with GLUCOTROL. They are usually transient and seldom require discontinuance of therapy. Laboratory Tests: The pattern of laboratory test abnormalities observed with GLUCOTROL was similar to that for other sulfonylureas. Occasional mild to moderate elevations of SGOT, LDH, alkaline phosphatase, BUN and creatinine were noted. One case of jaundice was reported. The relationship of these abnormalities to GLUCOTROL is uncertain, and they have rarely been associated with clinical symptoms. OVERDOSAGE There is no well documented experience with GLUCOTROL overdosage. The acute oral toxicity was extremely low in all species tested (LD50 greater than 4 g/kg). Overdosage of sulfonylureas including GLUCOTROL can produce hypoglycemia. Mild hypoglycemic symptoms without loss of consciousness or neurologic findings should be treated 7 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda aggressively with oral glucose and adjustments in drug dosage and/or meal patterns. Close monitoring should continue until the physician is assured that the patient is out of danger. Severe hypoglycemic reactions with coma, seizure, or other neurological impairment occur infrequently, but constitute medical emergencies requiring immediate hospitalization. If hypoglycemic coma is diagnosed or suspected, the patient should be given a rapid intravenous injection of concentrated (50%) glucose solution. This should be followed by a continuous infusion of a more dilute (10%) glucose solution at a rate that will maintain the blood glucose at a level above 100 mg/dL. Patients should be closely monitored for a minimum of 24 to 48 hours since hypoglycemia may recur after apparent clinical recovery. Clearance of GLUCOTROL from plasma would be prolonged in persons with liver disease. Because of the extensive protein binding of GLUCOTROL, dialysis is unlikely to be of benefit. DOSAGE AND ADMINISTRATION There is no fixed dosage regimen for the management of diabetes mellitus with GLUCOTROL or any other hypoglycemic agent. In addition to the usual monitoring of urinary glucose, the patient’s blood glucose must also be monitored periodically to determine the minimum effective dose for the patient; to detect primary failure, i.e., inadequate lowering of blood glucose at the maximum recommended dose of medication; and to detect secondary failure, i.e., loss of an adequate blood-glucose-lowering response after an initial period of effectiveness. Glycosylated hemoglobin levels may also be of value in monitoring the patient’s response to therapy. Short-term administration of GLUCOTROL may be sufficient during periods of transient loss of control in patients usually controlled well on diet. In general, GLUCOTROL should be given approximately 30 minutes before a meal to achieve the greatest reduction in postprandial hyperglycemia. Initial Dose: The recommended starting dose is 5 mg, given before breakfast. Geriatric patients or those with liver disease may be started on 2.5 mg. Titration: Dosage adjustments should ordinarily be in increments of 2.5–5 mg, as determined by blood glucose response. At least several days should elapse between titration steps. If response to a single dose is not satisfactory, dividing that dose may prove effective. The maximum recommended once daily dose is 15 mg. Doses above 15 mg should ordinarily be divided and given before meals of adequate caloric content. The maximum recommended total daily dose is 40 mg. Maintenance: Some patients may be effectively controlled on a once-a-day regimen, while others show better response with divided dosing. Total daily doses above 15 mg should ordinarily be divided. Total daily doses above 30 mg have been safely given on a b.i.d. basis to long-term patients. In elderly patients, debilitated or malnourished patients, and patients with impaired renal or hepatic function, the initial and maintenance dosing should be conservative to avoid hypoglycemic reactions (see PRECAUTIONS section). 8 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda Patients Receiving Insulin: As with other sulfonylurea-class hypoglycemics, many stable non-insulin-dependent diabetic patients receiving insulin may be safely placed on GLUCOTROL. When transferring patients from insulin to GLUCOTROL, the following general guidelines should be considered: For patients whose daily insulin requirement is 20 units or less, insulin may be discontinued and GLUCOTROL therapy may begin at usual dosages. Several days should elapse between GLUCOTROL titration steps. For patients whose daily insulin requirement is greater than 20 units, the insulin dose should be reduced by 50% and GLUCOTROL therapy may begin at usual dosages. Subsequent reductions in insulin dosage should depend on individual patient response. Several days should elapse between GLUCOTROL titration steps. During the insulin withdrawal period, the patient should test urine samples for sugar and ketone bodies at least three times daily. Patients should be instructed to contact the prescriber immediately if these tests are abnormal. In some cases, especially when patient has been receiving greater than 40 units of insulin daily, it may be advisable to consider hospitalization during the transition period. Patients Receiving Other Oral Hypoglycemic Agents: As with other sulfonylurea-class hypoglycemics, no transition period is necessary when transferring patients to GLUCOTROL. Patients should be observed carefully (1–2 weeks) for hypoglycemia when being transferred from longer half-life sulfonylureas (e.g., chlorpropamide) to GLUCOTROL due to potential overlapping of drug effect.

SCH 11460 SECTION 2 DIPROSONE LOTION PAGE 1 DRAFT LABELING XXXXXXXX PRODUCT INFORMATION DIPROSONE® brand of betamethasone dipropionate Lotion, USP 0.05% w/w (potency expressed as betamethasone) For Dermatologic Use Only- Not for Ophthalmic Use DESCRIPTION DIPROSONE Lotion contains betamethasone dipropionate, USP, a synthetic adrenocorticosteroid, for dermatologic use. Betamethasone, an analog of prednisolone, has high corticosteroid activity and slight mineralocorticoid activity. Betamethasone dipropionate is the 17, 21-dipropionate ester of betamethasone. Chemically, betamethasone dipropionate is 9-Fluoro-11β,17,21-trihydroxy-16β- methylpregna-1,4-diene-3,20-dione 17,21-dipropionate, with the empirical formula C28H37FO7, a molecular weight of 504.6, and the following structural formula: Betamethasone dipropionate is a white to creamy white, odorless crystalline powder, insoluble in water. Each gram of DIPROSONE Lotion 0.05% w/w contains: 0.643 mg betamethasone dipropionate, USP (equivalent to 0.5 mg betamethasone) in a lotion base of isopropyl alcohol, USP (39.25%) and purified water, USP; slightly thickened with carbomer 974P; the pH is adjusted to approximately 4.7 with sodium hydroxide.

For current labeling information, please visit https://www.fda.gov/drugsatfda SCH 11460 SECTION 2 DIPROSONE LOTION PAGE 2 DRAFT LABELING CLINICAL PHARMACOLOGY The corticosteroids are a class of compounds comprising steroid hormones, secreted by the adrenal cortex and their synthetic analogs. In pharmacologic doses corticosteroids are used primarily for their anti-inflammatory and/or immunosuppressive effects. Topical corticosteroids, such as betamethasone dipropionate, are effective in the treatment of corticosteroid-responsive dermatoses primarily because of their anti- inflammatory, antipruritic, and vasoconstrictive actions. However, while the physiologic, pharmacologic, and clinical effects of the corticosteroids are well known, the exact mechanisms of their actions in each disease are uncertain. Betamethasone dipropionate, a corticosteroid, has been shown to have topical (dermatologic) and systemic pharmacologic and metabolic effects characteristic of this class of drugs. Pharmacokinetics The extent of percutaneous absorption of topical corticosteroids is determined by many factors including the vehicle, the integrity of the epidermal barrier, and the use of occlusive dressings. (See DOSAGE AND ADMINISTRATION.) Topical corticosteroids can be absorbed from normal intact skin. Inflammation and/or other disease processes in the skin increase percutaneous absorption. Occlusive dressings substantially increase the percutaneous absorption of topical corticosteroids. (See DOSAGE AND ADMINISTRATION.) Once absorbed through the skin, topical corticosteroids are handled through pharmacokinetic pathways similar to systemically administered corticosteroids. Corticosteroids are bound to plasma proteins in varying degrees. Corticosteroids are metabolized primarily in the liver and are then excreted by the kidneys. Some of the topical corticosteroids and their metabolites are also excreted into the bile. Twenty-five pediatric patients ages 6 to 12 years, with atopic dermatitis, were enrolled in an open-label, hypothalamic-pituitary-adrenal (HPA) axis safety study. DIPROSONE Lotion was applied twice daily for 2 to 3 weeks over a mean body surface area of 45% (range 35% to 72%). In 11 of 15 (73%) evaluable patients, adrenal suppression was indicated by either a ≤ 5 mcg/dL pre-stimulation cortisol, or a cosyntropin post-stimulation cortisol ≤ 18 mcg/dL and an increase of < 7 mcg/dL from the baseline This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda SCH 11460 SECTION 2 DIPROSONE LOTION PAGE 3 DRAFT LABELING cortisol. Studies performed with DIPROSONE Lotion indicate that it is in the medium range of potency as compared with other topical corticosteroids. INDICATIONS AND USAGE DIPROSONE Lotion is a medium-potency corticosteroid indicated for relief of the inflammatory and pruritic manifestations of corticosteroid- responsive dermatoses in patients 13 years and older. CONTRAINDICATIONS DIPROSONE Lotion is contraindicated in patients who are hypersensitive to betamethasone dipropionate, to other corticosteroids, or to any ingredient in these preparations. PRECAUTIONS General Systemic absorption of topical corticosteroids has produced reversible hypothalamic-pituitary-adrenal (HPA) axis suppression, manifestations of Cushing's syndrome, hyperglycemia, and glucosuria in some patients. Conditions which augment systemic absorption include the application of the more potent steroids, use over large surface areas, prolonged use, and the addition of occlusive dressings. Use of more than one corticosteroid-containing product at the same time may increase total systemic glucocorticoid exposure. (See DOSAGE AND ADMINISTRATION.) Therefore, patients receiving a large dose of a potent topical steroid applied to a large surface area should be evaluated periodically for evidence of HPA axis suppression by using the urinary-free cortisol and ACTH stimulation tests. If HPA axis suppression is noted, an attempt should be made to withdraw the drug, to reduce the frequency of application, or to substitute a less potent steroid. Recovery of HPA axis function is generally prompt and complete upon discontinuation of the drug. In an open-label pediatric study of 15 evaluable patients, of the 11 subjects who showed evidence of suppression, 6 subjects were tested 2 weeks after discontinuation of DIPROSONE Lotion, 0.05%, and 4 of the 6 (67%) had complete recovery of HPA axis function. Infrequently, signs and symptoms of steroid withdrawal may occur, requiring supplemental systemic corticosteroids. This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda SCH 11460 SECTION 2 DIPROSONE LOTION PAGE 4 DRAFT LABELING Pediatric patients may absorb proportionally larger amounts of topical corticosteroids and thus be more susceptible to systemic toxicity. (See PRECAUTIONS- Pediatric Use.) If irritation develops, topical corticosteroids should be discontinued and appropriate therapy instituted. In the presence of dermatological infections, the use of an appropriate antifungal or antibacterial agent should be instituted. If a favorable response does not occur promptly, the corticosteroid should be discontinued until the infection has been adequately controlled. Information for Patients This information is intended to aid in the safe and effective use of this medication. It is not a disclosure of all possible adverse or intended effects. Patients using topical corticosteroids should receive the following information and instructions: 1. This medication is to be used as directed by the physician. It is for external use only. Avoid contact with the eyes. 2. Patients should be advised not to use this medication for any disorder other than that for which it was prescribed. 3. The treated skin area should not be bandaged or otherwise covered or wrapped as to be occlusive. (See DOSAGE AND ADMINISTRATION.) 4. Patients should report any signs of local adverse reactions. 5. Other corticosteroid-containing products should not be used with DIPROSONE Lotion without first talking to your physician. Laboratory Tests The following tests may be helpful in evaluating HPA axis suppression: Urinary-free cortisol test ACTH stimulation test This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda SCH 11460 SECTION 2 DIPROSONE LOTION PAGE 5 DRAFT LABELING Carcinogenesis, Mutagenesis, and Impairment of Fertility Long-term animal studies have not been performed to evaluate the carcinogenic potential of betamethasone dipropionate. Betamethasone was negative in the bacterial mutagenicity assay (Salmonella typhimurium and Escherichia coli), and in the mammalian cell mutagenicity assay (CHO/HGPRT). It was positive in the in-vitro human lymphocyte chromosome aberration assay, and equivocal in the in-vivo mouse bone marrow micronucleus assay. This pattern of response is similar to that of dexamethasone and hydrocortisone. Reproductive studies with betamethasone dipropionate carried out in rabbits at doses of 1.0 mg/kg by the intramuscular route and in mice up to 33 mg/kg by the intramuscular route indicated no impairment of fertility except for dose-related increases in fetal resorption rates in both species. These doses are approximately 0.5 and 4 fold the estimated maximum human dose based on a mg/m2 comparison, respectively. Pregnancy: Teratogenic effects: Pregnancy Category C: Corticosteroids are generally teratogenic in laboratory animals when administered systemically at relatively low dosage levels. Betamethasone dipropionate has been shown to be teratogenic in rabbits when given by the intramuscular route at doses of 0.05 mg/kg. This dose is approximately 0.03 fold the estimated maximum human dose based on a mg/m2 comparison. The abnormalities observed included umbilical hernias, cephalocele and cleft palates. Some corticosteroids have been shown to be teratogenic after dermal application in laboratory animals. There are no adequate and well-controlled studies in pregnant women on teratogenic effects from topically applied corticosteroids. Therefore, topical corticosteroids should be used during pregnancy only if the potential benefit justifies the This label may not be the latest approved by FDA.

Drugs of this class should not be used extensively on pregnant patients, in large amounts, or for prolonged periods of time. Nursing Mothers It is not known whether topical administration of corticosteroids could result in sufficient systemic absorption to produce detectable quantities in breast milk. Systemically administered corticosteroids are secreted into breast milk in quantities not likely to have a deleterious effect on the infant. Nevertheless, caution should be exercised when topical corticosteroids are prescribed for a nursing woman. Pediatric Use Use of DIPROSONE Lotion, 0.05% in pediatric patients 12 years of age and younger is not recommended. (See CLINICAL PHARMACOLOGY and ADVERSE REACTIONS Sections.) In an open-label study, 11 of 15 (73%) evaluable pediatric patients (aged 6 years-12 years old) using DIPROSONE Lotion for treatment of atopic dermatitis for 2-3 weeks demonstrated adrenal suppression. (See CLINICAL PHARMACOLOGY - Pharmacokinetics.) Pediatric patients may demonstrate greater susceptibility to topical corticosteroid- induced HPA axis suppression and Cushing's syndrome than mature patients because of a larger skin surface area to body weight ratio. Hypothalamic-pituitary-adrenal (HPA) axis suppression, Cushing's syndrome, and intracranial hypertension have been reported in pediatric patients receiving topical corticosteroids. Manifestations of adrenal suppression in pediatric patients include linear growth retardation, delayed weight gain, low plasma cortisol levels, and absence of response to ACTH stimulation. Manifestations of intracranial hypertension include bulging fontanelles, headaches, and bilateral papilledema. Administration of topical corticosteroids to pediatric patients should be limited to the least amount compatible with an effective therapeutic regimen. Chronic corticosteroid therapy may interfere with the growth and development of pediatric patients. ADVERSE REACTIONS The following local adverse reactions are reported infrequently when DIPROSONE Lotion is used as recommended in the DOSAGE AND ADMINISTRATION section. These reactions are listed in an approximate decreasing order of occurrence: burning, itching, irritation, dryness, folliculitis, hypertrichosis, This label may not be the latest approved by FDA.

Adverse reactions reported to be possibly or probably related to treatment with DIPROSONE Lotion during a pediatric study include: paresthesia (burning), erythema, erythematous rash, and dry skin. These adverse reactions each occurred in a different patient; 4% of the 25 patient population, respectively. An adverse reaction reported to be possibly or probably related to treatment in 2 different patients, 8%, of the 25 patients is puritis. Systemic absorption of topical corticosteroids has produced reversible hypothalamic-pituitary-adrenal (HPA) axis suppression, manifestations of Cushing's syndrome, hyperglycemia, and glucosuria in some patients. OVERDOSAGE Topically applied corticosteroids can be absorbed in sufficient amounts to produce systemic effects. (See PRECAUTIONS.) DOSAGE AND ADMINISTRATION Apply a few drops of DIPROSONE Lotion to the affected area and massage lightly until it disappears. Apply twice daily, in the morning and at night.

company logo Miacalcin® (calcitonin-salmon) Injection, Synthetic Rx only DESCRIPTION Calcitonin is a polypeptide hormone secreted by the parafollicular cells of the thyroid gland in mammals and by the ultimobranchial gland of birds and fish. Miacalcin® (calcitonin-salmon) Injection, Synthetic is a synthetic polypeptide of 32 amino acids in the same linear sequence that is found in calcitonin of salmon origin. This is shown by the following graphic formula: graphic formula It is provided in sterile solution for subcutaneous or intramuscular injection. Each milliliter contains: calcitonin-salmon 200 I.U., acetic acid, USP, 2.25 mg; phenol, USP, 5.0 mg; sodium acetate trihydrate, USP, 2.0 mg; sodium chloride, USP, 7.5 mg; water for injection, USP, qs to 1.0 mL. The activity of Miacalcin Injection is stated in International Units based on bioassay in comparison with the International Reference Preparation of calcitonin-salmon for Bioassay, distributed by the National Institute for Biological Standards and Control, Holly Hill, London. CLINICAL PHARMACOLOGY Calcitonin acts primarily on bone, but direct renal effects and actions on the gastrointestinal tract are also recognized. Calcitonin-salmon appears to have actions essentially identical to calcitonins of mammalian origin, but its potency per mg is greater and it has a longer duration of action. The actions of calcitonin on bone and its role in normal human bone physiology are still incompletely understood. Bone: Single injections of calcitonin cause a marked transient inhibition of the ongoing bone resorptive process. With prolonged use, there is a persistent, smaller decrease in the rate of bone resorption. Histologically, this is associated with a decreased number of osteoclasts and Reference ID: 3118265 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda an apparent decrease in their resorptive activity. Decreased osteocytic resorption may also be involved. There is some evidence that initially bone formation may be augmented by calcitonin through increased osteoblastic activity. However, calcitonin will probably not induce a long-term increase in bone formation. Animal studies indicate that endogenous calcitonin, primarily through its action on bone, participates with parathyroid hormone in the homeostatic regulation of blood calcium. Thus, high blood calcium levels cause increased secretion of calcitonin which, in turn, inhibits bone resorption. This reduces the transfer of calcium from bone to blood and tends to return blood calcium to the normal level. The importance of this process in humans has not been determined. In normal adults, who have a relatively low rate of bone resorption, the administration of exogenous calcitonin results in only a slight decrease in serum calcium. In normal children and in patients with generalized Paget’s disease, bone resorption is more rapid and decreases in serum calcium are more pronounced in response to calcitonin. Paget’s Disease of Bone (osteitis deformans): Paget's disease is a disorder of uncertain etiology characterized by abnormal and accelerated bone formation and resorption in one or more bones. In most patients, only small areas of bone are involved and the disease is not symptomatic. In a small fraction of patients, however, the abnormal bone may lead to bone pain and bone deformity, cranial and spinal nerve entrapment, or spinal cord compression. The increased vascularity of the abnormal bone may lead to high output congestive heart failure. Active Paget’s disease involving a large mass of bone may increase the urinary hydroxyproline excretion (reflecting breakdown of collagen-containing bone matrix) and serum alkaline phosphatase (reflecting increased bone formation). Calcitonin-salmon, presumably by an initial blocking effect on bone resorption, causes a decreased rate of bone turnover with a resultant fall in the serum alkaline phosphatase and urinary hydroxyproline excretion in approximately 2/3 of patients treated. These biochemical changes appear to correspond to changes toward more normal bone, as evidenced by a small number of documented examples of: 1) radiologic regression of Pagetic lesions, 2) improvement of impaired auditory nerve and other neurologic function, 3) decreases (measured) in abnormally elevated cardiac output. These improvements occur extremely rarely, if ever, spontaneously (elevated cardiac output may disappear over a period of years when the disease slowly enters a sclerotic phase; in the cases treated with calcitonin, however, the decreases were seen in less than one year.) Some patients with Paget’s disease, who have good biochemical and/or symptomatic responses initially, later relapse. Suggested explanations have included the formation of neutralizing antibodies and the development of secondary hyperparathyroidism, but neither suggestion appears to explain adequately the majority of relapses. Although the parathyroid hormone levels do appear to rise transiently during each hypocalcemic response to calcitonin, most investigators have been unable to demonstrate persistent hypersecretion of parathyroid hormone in patients treated chronically with calcitonin-salmon. Circulating antibodies to calcitonin after 2-18 months’ treatment have been reported in about half of the patients with Paget’s disease in whom antibody studies were done, but calcitonin treatment remained effective in many of these cases. Occasionally, patients with high Reference ID: 3118265 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda antibody titers are found. These patients usually will have suffered a biochemical relapse of Paget’s disease and are unresponsive to the acute hypocalcemic effects of calcitonin. Hypercalcemia: In clinical trials, calcitonin-salmon has been shown to lower the elevated serum calcium of patients with carcinoma (with or without demonstrated metastases), multiple myeloma, or primary hyperparathyroidism (lesser response). Patients with higher values for serum calcium tend to show greater reduction during calcitonin therapy. The decrease in calcium occurs about 2 hours after the first injection and lasts for about 6-8 hours. Calcitonin­ salmon given every 12 hours maintained a calcium lowering effect for about 5-8 days, the time period evaluated for most patients during the clinical studies. The average reduction of 8­ hour post-injection serum calcium during this period was about 9%. Kidney: Calcitonin increases the excretion of filtered phosphate, calcium, and sodium by decreasing their tubular reabsorption. In some patients, the inhibition of bone resorption by calcitonin is of such magnitude that the consequent reduction of filtered calcium load more than compensates for the decrease in tubular reabsorption of calcium. The result in these patients is a decrease rather than an increase in urinary calcium. Transient increases in sodium and water excretion may occur after the initial injection of calcitonin. In most patients, these changes return to pretreatment levels with continued therapy. Gastrointestinal Tract: Increasing evidence indicates that calcitonin has significant actions on the gastrointestinal tract. Short-term administration results in marked transient decreases in the volume and acidity of gastric juice and in the volume and the trypsin and amylase content of pancreatic juice. Whether these effects continue to be elicited after each injection of calcitonin during chronic therapy has not been investigated. Metabolism: Information from animal studies with calcitonin-salmon and from clinical studies with calcitonins of porcine and human origin suggest that calcitonin-salmon is rapidly metabolized by conversion to smaller inactive fragments, primarily in the kidneys, but also in the blood and peripheral tissues. A small amount of unchanged hormone and its inactive metabolites are excreted in the urine. The absolute bioavailability of salmon calcitonin is approximately 66% and 71% after intramuscular (i.m.) or subcutaneous (s.c.) injection, respectively. After subcutaneous administration, peak plasma levels are reached in approximately 23 minutes. The terminal half-life is approximately 58 minutes for i.m. administration and 59 to 64 minutes for s.c. administration. The apparent volume of distribution is 0.15-0.3 L/kg. It appears that calcitonin-salmon cannot cross the placental barrier and its passage to the cerebrospinal fluid or to breast milk has not been determined. INDICATIONS AND USAGE Miacalcin® (calcitonin-salmon) Injection, Synthetic is indicated for the treatment of symptomatic Paget’s disease of bone, for the treatment of hypercalcemia, and for the treatment of postmenopausal osteoporosis. Paget’s Disease: At the present time, effectiveness has been demonstrated principally in patients with moderate to severe disease characterized by polyostotic involvement with elevated serum alkaline phosphatase and urinary hydroxyproline excretion. Reference ID: 3118265 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda In these patients, the biochemical abnormalities were substantially improved (more than 30% reduction) in about 2/3 of patients studied, and bone pain was improved in a similar fraction. A small number of documented instances of reversal of neurologic deficits have occurred, including improvement in the basilar compression syndrome, and improvement of spinal cord and spinal nerve lesions. At present, there is too little experience to predict the likelihood of improvement of any given neurologic lesion. Hearing loss, the most common neurologic lesion of Paget’s disease, is improved infrequently (4 of 29 patients studied audiometrically). Patients with increased cardiac output due to extensive Paget’s disease have had measured decreases in cardiac output while receiving calcitonin. The number of treated patients in this category is still too small to predict how likely such a result will be. The large majority of patients with localized, especially monostotic disease do not develop symptoms and most patients with mild symptoms can be managed with analgesics. There is no evidence that the prophylactic use of calcitonin is beneficial in asymptomatic patients, although treatment may be considered in exceptional circumstances in which there is extensive involvement of the skull or spinal cord with the possibility of irreversible neurologic damage. In these instances, treatment would be based on the demonstrated effect of calcitonin on Pagetic bone, rather than on clinical studies in the patient population in question. Hypercalcemia: Miacalcin Injection is indicated for early treatment of hypercalcemic emergencies, along with other appropriate agents, when a rapid decrease in serum calcium is required, until more specific treatment of the underlying disease can be accomplished. It may also be added to existing therapeutic regimens for hypercalcemia such as intravenous fluids and furosemide, oral phosphate or corticosteroids, or other agents. Postmenopausal Osteoporosis: Miacalcin Injection is indicated for the treatment of postmenopausal osteoporosis in females greater than 5 years postmenopause with low bone mass relative to healthy premenopausal females. Miacalcin Injection should be reserved for patients who refuse or cannot tolerate estrogens or in whom estrogens are contraindicated. Use of Miacalcin Injection is recommended in conjunction with adequate calcium and vitamin D intake to prevent the progressive loss of bone mass. No evidence currently exists to indicate whether or not Miacalcin Injection decreases the risk of vertebral crush fractures or spinal deformity. A recent controlled study, which was discontinued prior to completion because of questions regarding its design and implementation, failed to demonstrate any benefit of salmon calcitonin on fracture rate. No adequate controlled trials have examined the effect of salmon calcitonin injection on vertebral bone mineral density beyond 1 year of treatment. Two placebo-controlled studies with salmon calcitonin have shown an increase in total body calcium at 1 year, followed by a trend to decreasing total body calcium (still above baseline) at 2 years. The minimum effective dose of Miacalcin Injection for prevention of vertebral bone mineral density loss has not been established. It has been suggested that those postmenopausal patients having increased rates of bone turnover may be more likely to respond to anti-resorptive agents such as Miacalcin Injection. CONTRAINDICATIONS Clinical allergy to synthetic calcitonin-salmon. Reference ID: 3118265 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda WARNINGS Allergic Reactions Because calcitonin is a polypeptide, the possibility of a systemic allergic reaction exists. Administration of calcitonin-salmon has been reported in a few cases to cause serious allergic-type reactions (e.g., bronchospasm, swelling of the tongue or throat, anaphylactic shock), including very rare reports of death attributed to anaphylaxis. The usual provisions should be made for the emergency treatment of such a reaction should it occur. Allergic reactions should be differentiated from generalized flushing and hypotension. For patients with suspected sensitivity to calcitonin, skin testing should be considered prior to treatment utilizing a dilute, sterile solution of Miacalcin® (calcitonin-salmon) Injection, Synthetic. Physicians may wish to refer patients who require skin testing to an allergist. A detailed skin testing protocol is available from the Medical Services Department of Novartis Pharmaceuticals Corporation. The incidence of osteogenic sarcoma is known to be increased in Paget’s disease. Pagetic lesions, with or without therapy, may appear by X-ray to progress markedly, possibly with some loss of definition of periosteal margins. Such lesions should be evaluated carefully to differentiate these from osteogenic sarcoma. PRECAUTIONS Drug Interactions Concomitant use of calcitonin and lithium may lead to a reduction in plasma lithium concentrations due to increased urinary clearance of lithium. The dose of lithium may need to be adjusted. General The administration of calcitonin possibly could lead to hypocalcemic tetany under special circumstances although no cases have yet been reported. Provisions for parenteral calcium administration should be available during the first several administrations of calcitonin. Laboratory Tests Periodic examinations of urine sediment of patients on chronic therapy are recommended. Coarse granular casts and casts containing renal tubular epithelial cells were reported in young adult volunteers at bed rest who were given calcitonin-salmon to study the effect of immobilization on osteoporosis. There was no other evidence of renal abnormality and the urine sediment became normal after calcitonin was stopped. Urine sediment abnormalities have not been reported by other investigators. Instructions for the Patient Careful instruction in sterile injection technique should be given to the patient, and to other persons who may administer Miacalcin® (calcitonin-salmon) Injection, Synthetic. Reference ID: 3118265 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda Carcinogenesis, Mutagenesis, and Impairment of Fertility An increased incidence of pituitary adenomas has been observed in one-year toxicity studies in Sprague-Dawley rats administered calcitonin-salmon at dosages of 20 and 80 I.U./kg/day and in Fisher 344 rats given 80 I.U./kg/day. The relevance of these findings to humans is unknown. Calcitonin-salmon was not mutagenic in tests using Salmonella typhimurium, Escherichia coli, and Chinese Hamster V79 cells. Pregnancy: Teratogenic Effects Category C Calcitonin-salmon has been shown to cause a decrease in fetal birth weights in rabbits when given in doses 14-56 times the dose recommended for human use. Since calcitonin does not cross the placental barrier, this finding may be due to metabolic effects on the pregnant animal. There are no adequate and well-controlled studies in pregnant women. Miacalcin Injection should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus. Nursing Mothers It is not known whether this drug is excreted in human milk. As a general rule, nursing should not be undertaken while a patient is on this drug since many drugs are excreted in human milk. Calcitonin has been shown to inhibit lactation in animals. Pediatric Use Disorders of bone in children referred to as juvenile Paget’s disease have been reported rarely. The relationship of these disorders to adult Paget’s disease has not been established and experience with the use of calcitonin in these disorders is very limited. There is no adequate data to support the use of Miacalcin Injection in children. ADVERSE REACTIONS Gastrointestinal System Nausea with or without vomiting has been noted in about 10% of patients treated with calcitonin. It is most evident when treatment is first initiated and tends to decrease or disappear with continued administration. Dermatologic/Hypersensitivity Local inflammatory reactions at the site of subcutaneous or intramuscular injection have been reported in about 10% of patients. Flushing of face or hands occurred in about 2-5% of patients. Skin rashes, nocturia, pruritus of the ear lobes, feverish sensation, pain in the eyes, poor appetite, abdominal pain, edema of feet, and salty taste have been reported in patients treated with calcitonin-salmon. Administration of calcitonin-salmon has been reported in a few cases to cause serious allergic-type reactions (e.g., bronchospasm, swelling of the tongue or throat, anaphylactic shock), including very rare reports of death attributed to anaphylaxis. (see WARNINGS). In addition, the following adverse events were reported with Miacalcin Injection. Reference ID: 3118265 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda Body as a Whole – General Disorders: influenza-like symptoms, fatigue, edema (facial, peripheral, and generalized), Musculoskeletal/Collagen: arthralgia, musculoskeletal pain Cardiovascular: hypertension Gastrointestinal: abdominal pain, diarrhea, Immune System Disorders: hypersensitivity, anaphylactic and anaphylactoid reactions, anaphylactic shock Urinary System: polyuria Central and Peripheral Nervous System: dizziness, headache, tremor. Vision: visual disturbance OVERDOSAGE A dose of l000 I.U. subcutaneously may produce nausea and vomiting as the only adverse effects. Doses of 32 units per kg per day for 1-2 days demonstrate no other adverse effects. Data on chronic high-dose administration are insufficient to judge toxicity. DOSAGE AND ADMINISTRATION Paget’s Disease: The recommended starting dose of Miacalcin® (calcitonin-salmon) Injection, Synthetic in Paget's disease is 100 I.U. (0.5 mL) per day administered subcutaneously (preferred for outpatient self-administration) or intramuscularly. Drug effect should be monitored by periodic measurement of serum alkaline phosphatase and 24-hour urinary hydroxyproline (if available) and evaluations of symptoms. A decrease toward normal of the biochemical abnormalities is usually seen, if it is going to occur, within the first few months. Bone pain may also decrease during that time. Improvement of neurologic lesions, when it occurs, requires a longer period of treatment, often more than one year. In many patients, doses of 50 I.U. (0.25 mL) per day or every other day are sufficient to maintain biochemical and clinical improvement. At the present time, however, there are insufficient data to determine whether this reduced dose will have the same effect as the higher dose on forming more normal bone structure. It appears preferable, therefore, to maintain the higher dose in any patient with serious deformity or neurological involvement. In any patient with a good response initially who later relapses, either clinically or biochemically, the possibility of antibody formation should be explored. The patient may be tested for antibodies by an appropriate specialized test or evaluated for the possibility of antibody formation by critical clinical evaluation. Patient compliance should also be assessed in the event of relapse. In patients who relapse, whether because of antibodies or for unexplained reasons, a dosage increase beyond 100 I.U. per day does not usually appear to elicit an improved response. Hypercalcemia: The recommended starting dose of Miacalcin Injection in hypercalcemia is 4 I.U./kg body weight every 12 hours by subcutaneous or intramuscular injection. If the response to this dose is not satisfactory after one or two days, the dose may be increased to Reference ID: 3118265 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda 8 I.U./kg every 12 hours. If the response remains unsatisfactory after two more days, the dose may be further increased to a maximum of 8 I.U./kg every 6 hours. Postmenopausal Osteoporosis: The minimum effective dose of Miacalcin Injection for the prevention of vertebral bone mineral density loss has not been established. Data from a single one-year placebo-controlled study with salmon calcitonin injection suggested that 100 I.U. (subcutaneously or intramuscularly) every other day might be effective in preserving vertebral bone mineral density. Baseline and interval monitoring of biochemical markers of bone resorption/turnover (e.g., fasting AM, second-voided urine hydroxyproline to creatinine ratio) and of bone mineral density may be useful in achieving the minimum effective dose. Patients should also receive supplemental calcium such as calcium carbonate 1.5 g daily and an adequate vitamin D intake (400 units daily). An adequate diet is also essential. If the volume of Miacalcin Injection to be injected exceeds 2 mL, intramuscular injection is preferable and multiple sites of injection should be used. Miacalcin vials should be inspected visually. If the solution is not clear and colorless, or contains any particles, or if the vial is damaged, do not administer the solution.

For current labeling information, please visit https://www.fda.gov/drugsatfda FULL PRESCRIBING INFORMATION 1 INDICATIONS AND USAGE 1.1 Treatment of Paget’s Disease of Bone Miacalcin injection is indicated for the treatment of symptomatic Paget’s disease of bone in patients with moderate to severe disease characterized by polyostotic involvement with elevated serum alkaline phosphatase and urinary hydroxyproline excretion. There is no evidence that the prophylactic use of calcitonin-salmon is beneficial in asymptomatic patients. Miacalcin injection should be used only in patients who do not respond to alternative treatments or for whom such treatments are not suitable (e.g., patients for whom other therapies are contraindicated or for patients who are intolerant or unwilling to use other therapies). 1.2 Treatment of Hypercalcemia Miacalcin injection is indicated for the early treatment of hypercalcemic emergencies, along with other appropriate agents, when a rapid decrease in serum calcium is required, until more specific treatment of the underlying disease can be accomplished. It may also be added to existing therapeutic regimens for hypercalcemia such as intravenous fluids and furosemide, oral phosphate or corticosteroids, or other agents. 1.3 Treatment of Postmenopausal Osteoporosis Miacalcin injection is indicated for the treatment of postmenopausal osteoporosis in women greater than 5 years postmenopause. The evidence of efficacy for calcitonin-salmon injection is based on increases in total body calcium observed in clinical trials. Fracture reduction efficacy has not been demonstrated. Miacalcin injection should be reserved for patients for whom alternative treatments are not suitable (e.g., patients for whom other therapies are contraindicated or for patients who are intolerant or unwilling to use other therapies). 1.4 Important Limitations of Use Due to the possible association between malignancy and calcitonin-salmon use, the need for continued therapy should be re-evaluated on a periodic basis [see Warnings and Precautions (5.3)]. 2 DOSAGE AND ADMINISTRATION 2.1 Paget’s Disease of Bone The recommended dose of Miacalcin injection for treatment of symptomatic Paget's disease of bone is 100 International Units (0.5 mL) per day administered subcutaneously or intramuscularly. 2.2 Hypercalcemia The recommended starting dose of Miacalcin injection for early treatment of hypercalcemia is 4 International Units/kg body weight every 12 hours by subcutaneous or intramuscular injection. If the response to this dose is not satisfactory after one or two days, the dose may be increased to 8 International Units/kg every 12 hours. If the response remains unsatisfactory after two more days, the dose may be further increased to a maximum of 8 International Units/kg every 6 hours. 2.3 Postmenopausal Osteoporosis The recommended dose of Miacalcin injection for treatment of postmenopausal osteoporosis in women greater than 5 years postmenopause is 100 International Units (0.5 mL) per day administered subcutaneously or intramuscularly. The minimum effective dose of Miacalcin injection for the prevention of vertebral bone mineral density loss has not been established. 2.4 Preparation and Administration Visually inspect Miacalcin vials. Miacalcin injection is a clear, colorless, solution. If the solution is not clear and colorless, or contains any particles, or if the vial is damaged, do not administer the solution. If the volume of Miacalcin injection to be injected exceeds 2 mL, intramuscular injection is preferable and the total dose should be distributed across multiple sites of injection. Instruct patients to use sterile injection technique when administering Miacalcin injection, and to dispose of needles properly. Reference ID: 3467860 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda 2.5 Recommendations for Calcium and Vitamin D Supplementation Patients who use Miacalcin injection for treatment of postmenopausal osteoporosis should receive adequate calcium (at least 1000 mg elemental calcium per day) and Vitamin D (at least 400 International Units per day). 3 DOSAGE FORMS AND STRENGTHS Miacalcin injection is available as a clear, colorless, sterile solution of synthetic calcitonin-salmon in individual 2 mL multi-dose vials containing 200 International Units per mL. 4 CONTRAINDICATIONS Hypersensitivity to calcitonin-salmon or any of the excipients. Reactions have included anaphylaxis with death, bronchospasm, and swelling of the tongue or throat [see Warnings and Precautions (5.1)]. 5 WARNINGS AND PRECAUTIONS 5.1 Hypersensitivity Reactions Serious hypersensitivity reactions have been reported in patients receiving Miacalcin injection, e.g., bronchospasm, swelling of the tongue or throat, anaphylactic shock, and death due to anaphylaxis. Appropriate medical support and monitoring measures should be readily available when Miacalcin injection is administered. If anaphylaxis or other severe hypersensitivity/allergic reactions occur, initiate appropriate treatment [see Contraindications (4)]. For patients with suspected hypersensitivity to calcitonin-salmon, skin testing should be considered prior to treatment utilizing a dilute, sterile solution of Miacalcin injection. Healthcare providers may wish to refer patients who require skin testing to an allergist. A detailed skin testing protocol is available from the Medical Services Department of Novartis Pharmaceuticals Corporation. 5.2 Hypocalcemia Hypocalcemia associated with tetany (i.e. muscle cramps, twitching) and seizure activity has been reported with Miacalcin injection therapy. Hypocalcemia must be corrected before initiating therapy. Other disorders affecting mineral metabolism (such as vitamin D deficiency) should also be effectively treated. In patients at risk for hypocalcemia, provisions for parenteral calcium administration should be available during the first several administrations of calcitonin­ salmon and serum calcium and symptoms of hypocalcemia should be monitored. Use of Miacalcin injection for the treatment of Paget’s disease or postmenopausal osteoporosis is recommended in conjunction with an adequate intake of calcium and vitamin D [see Dosage and Administration (2.5)]. 5.3 Malignancy In a meta-analysis of 21 randomized, controlled clinical trials with calcitonin-salmon (nasal spray or investigational oral formulations), the overall incidence of malignancies reported was higher among calcitonin-salmon-treated patients (4.1%) compared with placebo-treated patients (2.9%). This suggests an increased risk of malignancies in calcitonin-salmon­ treated patients compared to placebo-treated patients. It is not possible to exclude an increased risk when calcitonin­ salmon is administered long-term subcutaneously, intramuscularly, or intravenously. The benefits for the individual patient should be carefully considered against possible risks [see Adverse Reactions (6.1)]. 5.4 Antibody Formation Circulating antibodies to calcitonin-salmon have been reported with Miacalcin injection. The possibility of antibody formation should be considered in any patient with an initial response to Miacalcin injection who later stops responding to treatment [see Adverse Reactions (6.3)]. 5.5 Urine Sediment Abnormalities Coarse granular casts and casts containing renal tubular epithelial cells were reported in young adult volunteers at bed rest who were given injectable calcitonin-salmon to study the effect of immobilization on osteoporosis. There was no other evidence of renal abnormality and the urine sediment normalized after calcitonin-salmon was stopped. Periodic examinations of urine sediment should be considered. 6 ADVERSE REACTIONS The following serious adverse reactions are discussed in greater detail in other sections of the label:  Hypersensitivity Reactions, including anaphylaxis [see Warnings and Precautions (5.1)] Reference ID: 3467860 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda  Hypocalcemia [see Warnings and Precautions (5.2)]  Malignancy [see Warnings and Precautions (5.3)] 6.1 Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice. The safety of calcitonin-salmon injection was assessed in open-label trials several months to two years in duration. The most common adverse reactions are discussed below. Nausea: Nausea with or without vomiting has been noted in about 10% of patients treated with calcitonin-salmon. It is most evident when treatment is first initiated and tends to decrease or disappear with continued administration. Dermatologic Reactions: Local inflammatory reactions at the site of subcutaneous or intramuscular injection have been reported in about 10% of patients. Flushing of face or hands occurred in about 2-5% of patients. Skin rashes and pruritus of the ear lobes have also been reported. Other Adverse Reactions: Nocturia, feverish sensation, pain in the eyes, poor appetite, abdominal pain, pedal edema, and salty taste have been reported in patients treated with calcitonin-salmon injection. Malignancy A meta-analysis of 21 randomized, controlled clinical trials with calcitonin-salmon (nasal spray or investigational oral formulations) was conducted to assess the risk of malignancies in calcitonin-salmon-treated patients compared to placebo- treated patients. The trials in the meta-analysis ranged in duration from 6 months to 5 years and included a total of 10883 patients (6151 treated with calcitonin-salmon and 4732 treated with placebo). The overall incidence of malignancies reported in these 21 trials was higher among calcitonin-salmon-treated patients (254/6151 or 4.1%) compared with placebo-treated patients (137/4732 or 2.9%). Findings were similar when analyses were restricted to the 18 nasal spray only trials [calcitonin-salmon 122/2712 (4.5%); placebo 30/1309 (2.3%)]. The meta-analysis results suggest an increased risk of overall malignancies in calcitonin-salmon-treated patients compared to placebo-treated patients when all 21 trials are included and when the analysis is restricted to the 18 nasal spray only trials (see Table 1). It is not possible to exclude an increased risk when calcitonin-salmon is administered by the subcutaneous, intramuscular, or intravenous route because these routes of administration were not investigated in the meta-analysis. The increased malignancy risk seen with the meta-analysis was heavily influenced by a single large 5-year trial, which had an observed risk difference of 3.4% [95% CI (0.4%, 6.5%)]. Imbalances in risks were still observed when analyses excluded basal cell carcinoma (see Table 1); the data were not sufficient for further analyses by type of malignancy. A mechanism for these observations has not been identified. Although a definitive causal relationship between calcitonin-salmon use and malignancies cannot be established from this meta-analysis, the benefits for the individual patient should be carefully evaluated against all possible risks [see Warnings and Precautions (5.3)]. Table 1: Risk Difference for Malignancies in Calcitonin-Salmon-Treated Patients Compared with Placebo-Treated Patients Patients Malignancies Risk Difference1 (%) 95% Confidence Interval2 (%) All (nasal spray + oral) All 1.0 (0.3, 1.6) All (nasal spray + oral) Excluding basal cell carcinoma 0.5 (-0.1, 1.2) All (nasal spray only) All 1.4 (0.3, 2.6) All (nasal spray only) Excluding basal cell carcinoma 0.8 (-0.2, 1.8) 1 The overall adjusted risk difference is the difference between the percentage of patients who had any malignancy (or malignancy excluding basal cell carcinoma) in calcitonin-salmon and placebo treatment groups, using the Mantel-Haenszel (MH) fixed-effect method. A risk difference of 0 is suggestive of no difference in malignancy risks between the treatment groups. 2 The corresponding 95% confidence interval for the overall adjusted risk difference also based on MH fixed-effect method. Reference ID: 3467860 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda 6.2 Postmarketing Experience Because postmarketing adverse reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure. The following adverse reactions have been reported during post-approval use of Miacalcin injection. Allergic / Hypersensitivity Reactions: Serious hypersensitivity reactions have been reported in patients receiving calcitonin-salmon injection, e.g., bronchospasm, swelling of the tongue or throat, anaphylactic shock, and death due to anaphylaxis. Hypocalcemia: Hypocalcemia with tetany (i.e. muscle cramps, twitching) and seizure activity have been reported. Body as a Whole: influenza-like symptoms, fatigue, edema (facial, peripheral, and generalized) Musculoskeletal: arthralgia, musculoskeletal pain Cardiovascular: hypertension Gastrointestinal: abdominal pain, diarrhea Urinary System: polyuria Nervous System: dizziness, headache, paresthesia, tremor Vision: visual disturbance 6.3 Immunogenicity Consistent with the potentially immunogenic properties of medicinal products containing peptides, administration of Miacalcin may trigger the development of anti-calcitonin antibodies. Circulating antibodies to calcitonin-salmon after 2­ 18 months of treatment have been reported in about one-half of the patients with Paget’s disease in whom antibody studies were done. In some cases, high antibody titers are found; these patients usually will have a loss of response to treatment [see Warnings and Precautions (5.4)]. The incidence of antibody formation is highly dependent on the sensitivity and specificity of the assay. Additionally, the observed incidence of a positive antibody test result may be influenced by several factors, including assay methodology, sample handling, timing of sample collection, concomitant medications, and underlying disease. For these reasons, comparison of antibodies among different calcitonin-salmon products may be misleading. 7 DRUG INTERACTIONS No formal drug interaction studies have been performed with Miacalcin injection. Concomitant use of calcitonin-salmon and lithium may lead to a reduction in plasma lithium concentrations due to increased urinary clearance of lithium. The dose of lithium may require adjustment. 8 USE IN SPECIFIC POPULATIONS 8.1 Pregnancy Pregnancy Category C: Risk Summary There are no adequate and well-controlled studies in pregnant women. Miacalcin injection should be used during pregnancy only if the potential benefit justifies the use as compared with potential risks to the patient and fetus. Based on animal data, Miacalcin is predicted to have low probability of increasing the risk of adverse developmental outcomes above background risk. Animal Data Calcitonin-salmon has been shown to cause a decrease in fetal birth weights in rabbits when given by subcutaneous injection in doses 4-18 times the parenteral dose recommended for human use (of 54 International Units/m2). No embryo/fetal toxicities related to Miacalcin were reported from maternal subcutaneous daily doses in rats up to 80 International Units /kg/day from gestation day 6 to 15. Reference ID: 3467860 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda 8.3 Nursing Mothers It is not known whether this drug is excreted in human milk. No studies have been conducted to assess the impact of Miacalcin on milk production in humans, its presence in human breast milk, or its effects on the breast-fed child. Because many drugs are excreted in human milk, caution should be exercised when Miacalcin is administered to a nursing woman. Calcitonin has been shown to inhibit lactation in rats. 8.4 Pediatric Use Safety and effectiveness in pediatric patients have not been established. 8.5 Geriatric Use Clinical studies of Miacalcin injection did not include sufficient numbers of subjects aged 65 years and older to determine whether they respond differently from younger subjects. Other reported clinical experience has not identified differences in responses between the elderly and younger patients. In general, dose selection for an elderly patient should be cautious, usually starting at the low end of the dosing range, reflecting the greater frequency of decreased hepatic, renal, or cardiac function, and of concomitant disease or other drug therapy. 10 OVERDOSAGE The pharmacologic actions of Miacalcin injection suggest that hypocalcemic tetany could occur in overdose. Therefore, provisions for parenteral administration of calcium should be available for the treatment of overdose. A dose of calcitonin-salmon l000 International Units subcutaneously may produce nausea and vomiting. Doses of 32 International Units per kg per day for 1-2 days demonstrate no other adverse effects. Data on chronic high-dose administration are insufficient to assess toxicity. 11 DESCRIPTION Calcitonin is a polypeptide hormone secreted by the parafollicular cells of the thyroid gland in mammals and by the ultimobranchial gland of birds and fish. Miacalcin (calcitonin-salmon) injection, synthetic is a synthetic polypeptide of 32 amino acids in the same linear sequence that is found in calcitonin of salmon origin. This is shown by the following graphic formula: formula It is provided in sterile solution for subcutaneous or intramuscular injection. Each milliliter contains: calcitonin-salmon 200 International Units. Inactive Ingredients (per mL): acetic acid, USP, 2.25 mg; phenol, USP, 5.0 mg; sodium acetate trihydrate, USP, 2.0 mg; sodium chloride, USP, 7.5 mg; water for injection, USP. The activity of Miacalcin injection is stated in International Units based on bioassay in comparison with the International Reference Preparation of calcitonin-salmon for Bioassay, distributed by the National Institute for Biological Standards and Control, Holly Hill, London. Reference ID: 3467860 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda 12 CLINICAL PHARMACOLOGY 12.1 Mechanism of Action Calcitonin-salmon is a calcitonin receptor agonist. Calcitonin-salmon acts primarily on bone, but direct renal effects and actions on the gastrointestinal tract are also recognized. Calcitonin-salmon appears to have actions essentially identical to calcitonins of mammalian origin, but its potency per mg is greater and it has a longer duration of action. The actions of calcitonin on bone and its role in normal human bone physiology are still not completely elucidated, although calcitonin receptors have been discovered in osteoclasts and osteoblasts. 12.2 Pharmacodynamics Bone Single injections of calcitonin-salmon caused a marked transient inhibition of the ongoing bone resorptive process. With prolonged use, there is a persistent, smaller decrease in the rate of bone resorption. Histologically, this is associated with a decreased number of osteoclasts and an apparent decrease in their resorptive activity. In healthy adults, who have a relatively low rate of bone resorption, the administration of exogenous calcitonin-salmon results in decreases in serum calcium within the limits of the normal range. In healthy children and in patients whose bone resorption is more rapid, decreases in serum calcium are more pronounced in response to calcitonin-salmon. Kidney Studies with injectable calcitonin-salmon show increases in the excretion of filtered phosphate, calcium, and sodium by decreasing their tubular reabsorption. Gastrointestinal Tract Some evidence from studies with injectable preparations suggests that calcitonin-salmon may have effects on the gastrointestinal tract. Short-term administration of injectable calcitonin-salmon results in marked transient decreases in the volume and acidity of gastric juice and in the volume and the trypsin and amylase content of pancreatic juice. Whether these effects continue to be elicited after each injection of calcitonin-salmon during chronic therapy has not been investigated. 12.3 Pharmacokinetics The absolute bioavailability of calcitonin-salmon is approximately 66% and 71% after intramuscular or subcutaneous injection, respectively. After subcutaneous administration, peak plasma levels are reached in approximately 23 minutes. The terminal half-life is approximately 58 minutes for intramuscular administration and 59 to 64 minutes for subcutaneous administration. The apparent volume of distribution is 0.15-0.3 L/kg. 13 NONCLINICAL TOXICOLOGY 13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility Carcinogenicity The incidence of pituitary adenomas was increased in rats after one and two years of subcutaneous exposure to synthetic calcitonin-salmon. The significance of this finding to humans is unknown because pituitary adenomas are very common in rats as they age, the pituitary adenomas did not transform into metastatic tumors, there were no other clear treatment- related neoplasms, and synthetic calcitonin-salmon related neoplasms were not observed in mice after two years of dosing. Rat findings: The only clear neoplastic finding in rats dosed subcutaneously with calcitonin-salmon was an increase in the incidence of pituitary adenomas in male Fisher 344 rats and female Sprague Dawley rats after one year of dosing and male Sprague Dawley rats dosed for one and two years. In female Sprague Dawley rats, the incidence of pituitary adenomas after two years was high in all treatment groups (between 80% and 92% including the control groups) such that a treatment-related effect could not be distinguished from natural background incidence. The lowest dose in male Sprague Dawley rats that developed an increased incidence of pituitary adenomas after two years of dosing (1.7 International Units/kg/day) is approximately 1/6th of the maximum recommended subcutaneous dose in humans (100 International Units/day) based on body surface area conversion between rats and humans. The findings suggest that calcitonin-salmon reduced the latency period for development of non-functioning pituitary adenomas. Reference ID: 3467860 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda 14 Mouse findings: No carcinogenicity potential was evident in male or female mice dosed subcutaneously for two years with synthetic calcitonin-salmon at doses up to 800 International Units/kg/day. The 800 International Units/kg/day dose is approximately 39 times the maximum recommended subcutaneous dose in humans (100 International Units/day) based on body surface area conversion between mice and humans. Mutagenesis Synthetic calcitonin-salmon tested negative for mutagenicity using Salmonella typhimurium (5 strains) and Escherichia coli (2 strains), with and without rat liver metabolic activation, and was not clastogenic in a chromosome aberration test in Chinese Hamster V79 cells. There was no evidence that calcitonin-salmon was clastogenic in the in vivo mouse micronucleus test. Fertility Effects of calcitonin-salmon on fertility have not been assessed in animals. CLINICAL STUDIES 14.1 Paget’s Disease of Bone The trials used for the basis of approval for calcitonin-salmon injection for treatment of Paget’s disease of bone were conducted in patients with moderate to severe disease characterized by polyostotic involvement with elevated serum alkaline phosphatase and urinary hydroxyproline excretion. In open-label clinical trials of several months to two years duration with historical controls, biochemical abnormalities were substantially improved (more than 30% reduction) in about 2/3 of patients studied and bone pain was improved in a similar fraction. A small number of documented instances of reversal of neurologic deficits have occurred, including improvement in the basilar compression syndrome, and improvement of spinal cord and spinal nerve lesions. There is too little experience to predict the likelihood of improvement of any given neurologic lesion. Hearing loss is improved infrequently (4 of 29 patients studied by audiometry). Patients with increased cardiac output due to extensive Paget’s disease of bone have had measured decreases in cardiac output while receiving calcitonin-salmon. The number of treated patients in this category is too small to predict how likely such a result will be. There is no evidence that the prophylactic use of calcitonin-salmon is beneficial in asymptomatic patients. 14.2 Hypercalcemia In four open-label clinical trials enrolling 53 patients, calcitonin-salmon has been shown to lower elevated serum calcium levels of patients with carcinoma (with or without metastases), multiple myeloma, and primary hyperparathyroidism (lesser response). These patients were treated with calcitonin-salmon only when other methods of lowering serum calcium (hydration, oral phosphate, corticosteroids) were unsuccessful or unsuitable. With patients’ pre-therapy serum calcium levels as controls, reduction in serum calcium was evident within 1-2 hours of administration. The peak effect occurred within 24-48 hours of injection and administration of calcitonin-salmon every 12 hours maintained a hypocalcemic effect for approximately 5-8 days, the time period evaluated for most patients in the clinical trials. The average reduction of 8­ hour post-injection serum calcium was approximately 9% (2-3 mg/dL). Patients with higher values of serum calcium tended to show greater reductions during calcitonin-salmon treatment. 14.3 Postmenopausal Osteoporosis The trials used for the basis of approval for calcitonin-salmon injection for treatment of postmenopausal osteoporosis were two randomized, open-label, 2-year studies in postmenopausal women 50 – 74 years of age with total body calcium <85% of expected normal, and vertebral osteopenia (by x-ray criteria) and/or at least one atraumatic compression fracture. The primary efficacy endpoint was total body calcium measured by neutron activation analysis. Patients were randomized to calcitonin-salmon injection 100 International Units daily (subcutaneously or intramuscularly) at bedtime, or control. All subjects received daily supplements of 1200 mg calcium carbonate and 400 International Units of vitamin D. In both studies, total body calcium increased from baseline with calcitonin-salmon therapy at 1 year, followed by a trend to decreasing total body calcium (still above baseline) at 2 years. Thoracic and lumbar spine X-rays (AP/lateral) were obtained yearly. For the two studies combined (34 calcitonin-salmon and 35 control subjects), in the first year there was a total of 6 new vertebral compression fractures in the calcitonin­ salmon group and 5 in the control group. In the second year there were 7 new fractures in each group. Reference ID: 3467860 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda No evidence currently exists to indicate whether Miacalcin injection decreases the risk of osteoporotic fracture. A controlled study, which was prematurely discontinued, failed to demonstrate any benefit of calcitonin-salmon on fracture rate. No adequate controlled trials have examined the effect of calcitonin-salmon injection on vertebral bone mineral density beyond 1 year of treatment. Therefore, the minimum effective dose of Miacalcin injection for prevention of vertebral bone mineral density loss has not been established. In clinical studies of postmenopausal osteoporosis, bone biopsy and radial bone mass assessments at baseline and after 26 months of daily injectable calcitonin-salmon indicate that calcitonin therapy results in the formation of normal bone. 16 HOW SUPPLIED/STORAGE AND HANDLING How Supplied Miacalcin (calcitonin-salmon) injection, synthetic is available as a sterile solution in individual 2 mL multi-dose vials containing 200 International Units per mL .......................NDC 0078-0149-23 Storage and Handling Store in refrigerator between 2°C-8°C (36°F-46°F). 17 PATIENT COUNSELING INFORMATION  Instruct patients and other persons who may administer Miacalcin injection in sterile injection technique.

For current labeling information, please visit https://www.fda.gov/drugsatfda FULL PRESCRIBING INFORMATION 1 INDICATIONS AND USAGE 1.1 Treatment of Paget’s Disease of Bone Miacalcin injection is indicated for the treatment of symptomatic Paget’s disease of bone in patients with moderate to severe disease characterized by polyostotic involvement with elevated serum alkaline phosphatase and urinary hydroxyproline excretion. There is no evidence that the prophylactic use of calcitonin-salmon is beneficial in asymptomatic patients. Miacalcin injection should be used only in patients who do not respond to alternative treatments or for whom such treatments are not suitable (e.g., patients for whom other therapies are contraindicated or for patients who are intolerant or unwilling to use other therapies). 1.2 Treatment of Hypercalcemia Miacalcin injection is indicated for the early treatment of hypercalcemic emergencies, along with other appropriate agents, when a rapid decrease in serum calcium is required, until more specific treatment of the underlying disease can be accomplished. It may also be added to existing therapeutic regimens for hypercalcemia such as intravenous fluids and furosemide, oral phosphate or corticosteroids, or other agents. 1.3 Treatment of Postmenopausal Osteoporosis Miacalcin injection is indicated for the treatment of postmenopausal osteoporosis in women greater than 5 years postmenopause. The evidence of efficacy for calcitonin-salmon injection is based on increases in total body calcium observed in clinical trials. Fracture reduction efficacy has not been demonstrated. Miacalcin injection should be reserved for patients for whom alternative treatments are not suitable (e.g., patients for whom other therapies are contraindicated or for patients who are intolerant or unwilling to use other therapies). 1.4 Important Limitations of Use Due to the possible association between malignancy and calcitonin-salmon use, the need for continued therapy should be re-evaluated on a periodic basis [see Warnings and Precautions (5.3)]. 2 DOSAGE AND ADMINISTRATION 2.1 Paget’s Disease of Bone The recommended dose of Miacalcin injection for treatment of symptomatic Paget's disease of bone is 100 International Units (0.5 mL) per day administered subcutaneously or intramuscularly. 2.2 Hypercalcemia The recommended starting dose of Miacalcin injection for early treatment of hypercalcemia is 4 International Units/kg body weight every 12 hours by subcutaneous or intramuscular injection. If the response to this dose is not satisfactory after one or two days, the dose may be increased to 8 International Units/kg every 12 hours. If the response remains unsatisfactory after two more days, the dose may be further increased to a maximum of 8 International Units/kg every 6 hours. 2.3 Postmenopausal Osteoporosis The recommended dose of Miacalcin injection for treatment of postmenopausal osteoporosis in women greater than 5 years postmenopause is 100 International Units (0.5 mL) per day administered subcutaneously or intramuscularly. The minimum effective dose of Miacalcin injection for the prevention of vertebral bone mineral density loss has not been established. 2.4 Preparation and Administration Visually inspect Miacalcin vials. Miacalcin injection is a clear, colorless, solution. If the solution is not clear and colorless, or contains any particles, or if the vial is damaged, do not administer the solution. If the volume of Miacalcin injection to be injected exceeds 2 mL, intramuscular injection is preferable and the total dose should be distributed across multiple sites of injection. Instruct patients to use sterile injection technique when administering Miacalcin injection, and to dispose of needles properly. Reference ID: 3696059 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda 2.5 Recommendations for Calcium and Vitamin D Supplementation Patients who use Miacalcin injection for treatment of postmenopausal osteoporosis should receive adequate calcium (at least 1000 mg elemental calcium per day) and vitamin D (at least 400 International Units per day). 3 DOSAGE FORMS AND STRENGTHS Miacalcin injection is available as a clear, colorless, sterile solution of synthetic calcitonin-salmon in individual 2 mL multi-dose vials containing 200 International Units per mL. 4 CONTRAINDICATIONS Hypersensitivity to calcitonin-salmon or any of the excipients. Reactions have included anaphylaxis with death, bronchospasm, and swelling of the tongue or throat [see Warnings and Precautions (5.1)]. 5 WARNINGS AND PRECAUTIONS 5.1 Hypersensitivity Reactions Serious hypersensitivity reactions have been reported in patients receiving Miacalcin injection, e.g., bronchospasm, swelling of the tongue or throat, anaphylactic shock, and death due to anaphylaxis. Appropriate medical support and monitoring measures should be readily available when Miacalcin injection is administered. If anaphylaxis or other severe hypersensitivity/allergic reactions occur, initiate appropriate treatment [see Contraindications (4)]. For patients with suspected hypersensitivity to calcitonin-salmon, skin testing should be considered prior to treatment utilizing a dilute, sterile solution of Miacalcin injection. Healthcare providers may wish to refer patients who require skin testing to an allergist. A detailed skin testing protocol is available from the Medical Services Department of Novartis Pharmaceuticals Corporation. 5.2 Hypocalcemia Hypocalcemia associated with tetany (i.e., muscle cramps, twitching) and seizure activity has been reported with Miacalcin injection therapy. Hypocalcemia must be corrected before initiating therapy. Other disorders affecting mineral metabolism (such as vitamin D deficiency) should also be effectively treated. In patients at risk for hypocalcemia, provisions for parenteral calcium administration should be available during the first several administrations of calcitonin­ salmon and serum calcium and symptoms of hypocalcemia should be monitored. Use of Miacalcin injection for the treatment of Paget’s disease or postmenopausal osteoporosis is recommended in conjunction with an adequate intake of calcium and vitamin D [see Dosage and Administration (2.5)]. 5.3 Malignancy In a meta-analysis of 21 randomized, controlled clinical trials with calcitonin-salmon (nasal spray or investigational oral formulations), the overall incidence of malignancies reported was higher among calcitonin-salmon-treated patients (4.1%) compared with placebo-treated patients (2.9%). This suggests an increased risk of malignancies in calcitonin-salmon­ treated patients compared to placebo-treated patients. It is not possible to exclude an increased risk when calcitonin­ salmon is administered long-term subcutaneously, intramuscularly, or intravenously. The benefits for the individual patient should be carefully considered against possible risks [see Adverse Reactions (6.1)]. 5.4 Antibody Formation Circulating antibodies to calcitonin-salmon have been reported with Miacalcin injection. The possibility of antibody formation should be considered in any patient with an initial response to Miacalcin injection who later stops responding to treatment [see Adverse Reactions (6.3)]. 5.5 Urine Sediment Abnormalities Coarse granular casts and casts containing renal tubular epithelial cells were reported in young adult volunteers at bed rest who were given injectable calcitonin-salmon to study the effect of immobilization on osteoporosis. There was no other evidence of renal abnormality and the urine sediment normalized after calcitonin-salmon was stopped. Periodic examinations of urine sediment should be considered. 6 ADVERSE REACTIONS The following serious adverse reactions are discussed in greater detail in other sections of the label: • Hypersensitivity Reactions, including anaphylaxis [see Warnings and Precautions (5.1)] Reference ID: 3696059 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda • Hypocalcemia [see Warnings and Precautions (5.2)] • Malignancy [see Warnings and Precautions (5.3)] 6.1 Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice. The safety of calcitonin-salmon injection was assessed in open-label trials several months to two years in duration. The most common adverse reactions are discussed below. Nausea: Nausea with or without vomiting has been noted in about 10% of patients treated with calcitonin-salmon. It is most evident when treatment is first initiated and tends to decrease or disappear with continued administration. Dermatologic Reactions: Local inflammatory reactions at the site of subcutaneous or intramuscular injection have been reported in about 10% of patients. Flushing of face or hands occurred in about 2%–5% of patients. Skin rashes and pruritus of the ear lobes have also been reported. Other Adverse Reactions: Nocturia, feverish sensation, pain in the eyes, poor appetite, abdominal pain, pedal edema, and salty taste have been reported in patients treated with calcitonin-salmon injection. Malignancy A meta-analysis of 21 randomized, controlled clinical trials with calcitonin-salmon (nasal spray or investigational oral formulations) was conducted to assess the risk of malignancies in calcitonin-salmon-treated patients compared to placebo- treated patients. The trials in the meta-analysis ranged in duration from 6 months to 5 years and included a total of 10883 patients (6151 treated with calcitonin-salmon and 4732 treated with placebo). The overall incidence of malignancies reported in these 21 trials was higher among calcitonin-salmon-treated patients (254/6151 or 4.1%) compared with placebo-treated patients (137/4732 or 2.9%). Findings were similar when analyses were restricted to the 18 nasal spray only trials [calcitonin-salmon 122/2712 (4.5%); placebo 30/1309 (2.3%)]. The meta-analysis results suggest an increased risk of overall malignancies in calcitonin-salmon-treated patients compared to placebo-treated patients when all 21 trials are included and when the analysis is restricted to the 18 nasal spray only trials (see Table 1). It is not possible to exclude an increased risk when calcitonin-salmon is administered by the subcutaneous, intramuscular, or intravenous route because these routes of administration were not investigated in the meta-analysis. The increased malignancy risk seen with the meta-analysis was heavily influenced by a single large 5-year trial, which had an observed risk difference of 3.4% [95% CI (0.4%, 6.5%)]. Imbalances in risks were still observed when analyses excluded basal cell carcinoma (see Table 1); the data were not sufficient for further analyses by type of malignancy. A mechanism for these observations has not been identified. Although a definitive causal relationship between calcitonin-salmon use and malignancies cannot be established from this meta-analysis, the benefits for the individual patient should be carefully evaluated against all possible risks [see Warnings and Precautions (5.3)]. Table 1: Risk Difference for Malignancies in Calcitonin-Salmon-Treated Patients Compared with Placebo-Treated Patients Patients Malignancies Risk Difference1 (%) 95% Confidence Interval2 (%) All (nasal spray + oral) All 1.0 (0.3, 1.6) All (nasal spray + oral) Excluding basal cell carcinoma 0.5 (-0.1, 1.2) All (nasal spray only) All 1.4 (0.3, 2.6) All (nasal spray only) Excluding basal cell carcinoma 0.8 (-0.2, 1.8) 1 The overall adjusted risk difference is the difference between the percentage of patients who had any malignancy (or malignancy excluding basal cell carcinoma) in calcitonin-salmon and placebo treatment groups, using the Mantel-Haenszel (MH) fixed-effect method. A risk difference of 0 is suggestive of no difference in malignancy risks between the treatment groups. 2 The corresponding 95% confidence interval for the overall adjusted risk difference also based on MH fixed-effect method. Reference ID: 3696059 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda 6.2 Postmarketing Experience Because postmarketing adverse reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure. The following adverse reactions have been reported during post-approval use of Miacalcin injection. Allergic / Hypersensitivity Reactions: Serious hypersensitivity reactions have been reported in patients receiving calcitonin-salmon injection, e.g., bronchospasm, swelling of the tongue or throat, anaphylactic shock, and death due to anaphylaxis. Skin and subcutaneous tissue disorders: Urticaria Hypocalcemia: Hypocalcemia with tetany (i.e. muscle cramps, twitching) and seizure activity have been reported. Body as a Whole: influenza-like symptoms, fatigue, edema (facial, peripheral, and generalized) Musculoskeletal: arthralgia, musculoskeletal pain Cardiovascular: hypertension Gastrointestinal: abdominal pain, diarrhea Urinary System: polyuria Nervous System: dizziness, headache, paresthesia, tremor Vision: visual disturbance 6.3 Immunogenicity Consistent with the potentially immunogenic properties of medicinal products containing peptides, administration of Miacalcin may trigger the development of anti-calcitonin antibodies. Circulating antibodies to calcitonin-salmon after 2­ 18 months of treatment have been reported in about one-half of the patients with Paget’s disease in whom antibody studies were done. In some cases, high antibody titers are found; these patients usually will have a loss of response to treatment [see Warnings and Precautions (5.4)]. The incidence of antibody formation is highly dependent on the sensitivity and specificity of the assay. Additionally, the observed incidence of a positive antibody test result may be influenced by several factors, including assay methodology, sample handling, timing of sample collection, concomitant medications, and underlying disease. For these reasons, comparison of antibodies among different calcitonin-salmon products may be misleading. 7 DRUG INTERACTIONS No formal drug interaction studies have been performed with Miacalcin injection. Concomitant use of calcitonin-salmon and lithium may lead to a reduction in plasma lithium concentrations due to increased urinary clearance of lithium. The dose of lithium may require adjustment. 8 USE IN SPECIFIC POPULATIONS 8.1 Pregnancy Pregnancy Category C: Risk Summary There are no adequate and well-controlled studies in pregnant women. Miacalcin injection should be used during pregnancy only if the potential benefit justifies the use as compared with potential risks to the patient and fetus. Based on animal data, Miacalcin is predicted to have low probability of increasing the risk of adverse developmental outcomes above background risk. Animal Data Calcitonin-salmon has been shown to cause a decrease in fetal birth weights in rabbits when given by subcutaneous injection in doses 4-18 times the parenteral dose recommended for human use (of 54 International Units/m2). No embryo/fetal toxicities related to Miacalcin were reported from maternal subcutaneous daily doses in rats up to 80 International Units /kg/day from gestation day 6 to 15. Reference ID: 3696059 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda 8.3 Nursing Mothers It is not known whether this drug is excreted in human milk. No studies have been conducted to assess the impact of Miacalcin on milk production in humans, its presence in human breast milk, or its effects on the breastfed child. Because many drugs are excreted in human milk, caution should be exercised when Miacalcin is administered to a nursing woman. Calcitonin has been shown to inhibit lactation in rats. 8.4 Pediatric Use Safety and effectiveness in pediatric patients have not been established. 8.5 Geriatric Use Clinical studies of Miacalcin injection did not include sufficient numbers of subjects aged 65 years and older to determine whether they respond differently from younger subjects. Other reported clinical experience has not identified differences in responses between the elderly and younger patients. In general, dose selection for an elderly patient should be cautious, usually starting at the low end of the dosing range, reflecting the greater frequency of decreased hepatic, renal, or cardiac function, and of concomitant disease or other drug therapy. 10 OVERDOSAGE The pharmacologic actions of Miacalcin injection suggest that hypocalcemic tetany could occur in overdose. Therefore, provisions for parenteral administration of calcium should be available for the treatment of overdose. A dose of calcitonin-salmon l000 International Units subcutaneously may produce nausea and vomiting. Doses of 32 International Units per kg per day for 1–2 days demonstrate no other adverse effects. Data on chronic high-dose administration are insufficient to assess toxicity. 11 DESCRIPTION Calcitonin is a polypeptide hormone secreted by the parafollicular cells of the thyroid gland in mammals and by the ultimobranchial gland of birds and fish. Miacalcin (calcitonin-salmon) injection, synthetic is a synthetic polypeptide of 32 amino acids in the same linear sequence that is found in calcitonin of salmon origin. This is shown by the following graphic formula: graphic formula It is provided in sterile solution for subcutaneous or intramuscular injection. Each milliliter contains: calcitonin-salmon 200 International Units. Inactive Ingredients (per mL): acetic acid, USP, 2.25 mg; phenol, USP, 5.0 mg; sodium acetate trihydrate, USP, 2.0 mg; sodium chloride, USP, 7.5 mg; water for injection, USP. The activity of Miacalcin injection is stated in International Units based on bioassay in comparison with the International Reference Preparation of calcitonin-salmon for Bioassay, distributed by the National Institute for Biological Standards and Control, Holly Hill, London. Reference ID: 3696059 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda 12 CLINICAL PHARMACOLOGY 12.1 Mechanism of Action Calcitonin-salmon is a calcitonin receptor agonist. Calcitonin-salmon acts primarily on bone, but direct renal effects and actions on the gastrointestinal tract are also recognized. Calcitonin-salmon appears to have actions essentially identical to calcitonins of mammalian origin, but its potency per mg is greater and it has a longer duration of action. The actions of calcitonin on bone and its role in normal human bone physiology are still not completely elucidated, although calcitonin receptors have been discovered in osteoclasts and osteoblasts. 12.2 Pharmacodynamics Bone Single injections of calcitonin-salmon caused a marked transient inhibition of the ongoing bone resorptive process. With prolonged use, there is a persistent, smaller decrease in the rate of bone resorption. Histologically, this is associated with a decreased number of osteoclasts and an apparent decrease in their resorptive activity. In healthy adults, who have a relatively low rate of bone resorption, the administration of exogenous calcitonin-salmon results in decreases in serum calcium within the limits of the normal range. In healthy children and in patients whose bone resorption is more rapid, decreases in serum calcium are more pronounced in response to calcitonin-salmon. Kidney Studies with injectable calcitonin-salmon show increases in the excretion of filtered phosphate, calcium, and sodium by decreasing their tubular reabsorption. Gastrointestinal Tract Some evidence from studies with injectable preparations suggests that calcitonin-salmon may have effects on the gastrointestinal tract. Short-term administration of injectable calcitonin-salmon results in marked transient decreases in the volume and acidity of gastric juice and in the volume and the trypsin and amylase content of pancreatic juice. Whether these effects continue to be elicited after each injection of calcitonin-salmon during chronic therapy has not been investigated. 12.3 Pharmacokinetics The absolute bioavailability of calcitonin-salmon is approximately 66% and 71% after intramuscular or subcutaneous injection, respectively. After subcutaneous administration, peak plasma levels are reached in approximately 23 minutes. The terminal half-life is approximately 58 minutes for intramuscular administration and 59 to 64 minutes for subcutaneous administration. The apparent volume of distribution is 0.15––0.3 L/kg. 13 NONCLINICAL TOXICOLOGY 13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility Carcinogenicity The incidence of pituitary adenomas was increased in rats after one and two years of subcutaneous exposure to synthetic calcitonin-salmon. The significance of this finding to humans is unknown because pituitary adenomas are very common in rats as they age, the pituitary adenomas did not transform into metastatic tumors, there were no other clear treatment- related neoplasms, and synthetic calcitonin-salmon related neoplasms were not observed in mice after two years of dosing. Rat findings: The only clear neoplastic finding in rats dosed subcutaneously with calcitonin-salmon was an increase in the incidence of pituitary adenomas in male Fisher 344 rats and female Sprague Dawley rats after one year of dosing and male Sprague Dawley rats dosed for one and two years. In female Sprague Dawley rats, the incidence of pituitary adenomas after two years was high in all treatment groups (between 80% and 92% including the control groups) such that a treatment-related effect could not be distinguished from natural background incidence. The lowest dose in male Sprague Dawley rats that developed an increased incidence of pituitary adenomas after two years of dosing (1.7 International Units/kg/day) is approximately 1/6th of the maximum recommended subcutaneous dose in humans (100 International Units/day) based on body surface area conversion between rats and humans. The findings suggest that calcitonin-salmon reduced the latency period for development of non-functioning pituitary adenomas. Reference ID: 3696059 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda 14 Mouse findings: No carcinogenicity potential was evident in male or female mice dosed subcutaneously for two years with synthetic calcitonin-salmon at doses up to 800 International Units/kg/day. The 800 International Units/kg/day dose is approximately 39 times the maximum recommended subcutaneous dose in humans (100 International Units/day) based on body surface area conversion between mice and humans. Mutagenesis Synthetic calcitonin-salmon tested negative for mutagenicity using Salmonella typhimurium (5 strains) and Escherichia coli (2 strains), with and without rat liver metabolic activation, and was not clastogenic in a chromosome aberration test in Chinese Hamster V79 cells. There was no evidence that calcitonin-salmon was clastogenic in the in vivo mouse micronucleus test. Fertility Effects of calcitonin-salmon on fertility have not been assessed in animals. CLINICAL STUDIES 14.1 Paget’s Disease of Bone The trials used for the basis of approval for calcitonin-salmon injection for treatment of Paget’s disease of bone were conducted in patients with moderate to severe disease characterized by polyostotic involvement with elevated serum alkaline phosphatase and urinary hydroxyproline excretion. In open-label clinical trials of several months to two years duration with historical controls, biochemical abnormalities were substantially improved (more than 30% reduction) in about 2/3 of patients studied and bone pain was improved in a similar fraction. A small number of documented instances of reversal of neurologic deficits have occurred, including improvement in the basilar compression syndrome, and improvement of spinal cord and spinal nerve lesions. There is too little experience to predict the likelihood of improvement of any given neurologic lesion. Hearing loss is improved infrequently (4 of 29 patients studied by audiometry). Patients with increased cardiac output due to extensive Paget’s disease of bone have had measured decreases in cardiac output while receiving calcitonin-salmon. The number of treated patients in this category is too small to predict how likely such a result will be. There is no evidence that the prophylactic use of calcitonin-salmon is beneficial in asymptomatic patients. 14.2 Hypercalcemia In four open-label clinical trials enrolling 53 patients, calcitonin-salmon has been shown to lower elevated serum calcium levels of patients with carcinoma (with or without metastases), multiple myeloma, and primary hyperparathyroidism (lesser response). These patients were treated with calcitonin-salmon only when other methods of lowering serum calcium (hydration, oral phosphate, corticosteroids) were unsuccessful or unsuitable. With patients’ pre-therapy serum calcium levels as controls, reduction in serum calcium was evident within 1–2 hours of administration. The peak effect occurred within 24–48 hours of injection and administration of calcitonin-salmon every 12 hours maintained a hypocalcemic effect for approximately 5–8 days, the time period evaluated for most patients in the clinical trials. The average reduction of 8­ hour post-injection serum calcium was approximately 9% (2–3 mg/dL). Patients with higher values of serum calcium tended to show greater reductions during calcitonin-salmon treatment. 14.3 Postmenopausal Osteoporosis The trials used for the basis of approval for calcitonin-salmon injection for treatment of postmenopausal osteoporosis were two randomized, open-label, 2-year studies in postmenopausal women 50–74 years of age with total body calcium <85% of expected normal, and vertebral osteopenia (by x-ray criteria) and/or at least one atraumatic compression fracture. The primary efficacy endpoint was total body calcium measured by neutron activation analysis. Patients were randomized to calcitonin-salmon injection 100 International Units daily (subcutaneously or intramuscularly) at bedtime, or control. All subjects received daily supplements of 1200 mg calcium carbonate and 400 International Units of vitamin D. In both studies, total body calcium increased from baseline with calcitonin-salmon therapy at 1 year, followed by a trend to decreasing total body calcium (still above baseline) at 2 years. Thoracic and lumbar spine X-rays (AP/lateral) were obtained yearly. For the two studies combined (34 calcitonin-salmon and 35 control subjects), in the first year there was a total of 6 new vertebral compression fractures in the calcitonin­ salmon group and 5 in the control group. In the second year there were 7 new fractures in each group. Reference ID: 3696059 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda No evidence currently exists to indicate whether Miacalcin injection decreases the risk of osteoporotic fracture. A controlled study, which was prematurely discontinued, failed to demonstrate any benefit of calcitonin-salmon on fracture rate. No adequate controlled trials have examined the effect of calcitonin-salmon injection on vertebral bone mineral density beyond 1 year of treatment. Therefore, the minimum effective dose of Miacalcin injection for prevention of vertebral bone mineral density loss has not been established. In clinical studies of postmenopausal osteoporosis, bone biopsy and radial bone mass assessments at baseline and after 26 months of daily injectable calcitonin-salmon indicate that calcitonin therapy results in the formation of normal bone. 16 HOW SUPPLIED/STORAGE AND HANDLING How Supplied Miacalcin (calcitonin-salmon) injection, synthetic is available as a sterile solution in individual 2 mL multi-dose vials containing 200 International Units per mL .......................NDC 0078-0149-23 Storage and Handling Store in refrigerator between 2°C–8°C (36°F–46°F). 17 PATIENT COUNSELING INFORMATION • Instruct patients and other persons who may administer Miacalcin injection in sterile injection technique.

NDA 16-059/S-096, 17-814/S-039, 18-332/S-029 Page 3 CAPSULES, ORAL SUSPENSION and SUPPOSITORIES INDOCIN® (INDOMETHACIN) Cardiovascular Risk • NSAIDs may cause an increased risk of serious cardiovascular thrombotic events, myocardial infarction, and stroke, which can be fatal. This risk may increase with duration of use. Patients with cardiovascular disease or risk factors for cardiovascular disease may be at a greater risk (See WARNING). • INDOCIN is contraindicated for the treatment of peri-operative pain in the setting of coronary artery bypass graft (CABG) surgery (see WARNINGS). Gastrointestinal Risk • NSAIDs cause an increased risk of serious gastrointestinal adverse events including bleeding, ulceration, and perforation of the stomach or intestines, which can be fatal. These events can occur at any time during use and without warning symptoms. Elderly patients are at greater risk for serious gastrointestinal events (See WARNINGS). DESCRIPTION INDOCIN* (Indomethacin) cannot be considered a simple analgesic and should not be used in conditions other than those recommended under INDICATIONS. INDOCIN is supplied in three dosage forms. Capsules INDOCIN for oral administration contain either 25 mg or 50 mg of indomethacin and the following inactive ingredients: colloidal silicon dioxide, FD&C Blue 1, FD&C Red 3, gelatin, lactose, lecithin, magnesium stearate, and titanium dioxide. Suspension INDOCIN for oral use contains 25 mg of indomethacin per 5 mL, alcohol 1%, and sorbic acid 0.1% added as a preservative and the following inactive ingredients: antifoam AF emulsion, flavors, purified water, sodium hydroxide or hydrochloric acid to adjust pH, sorbitol solution, and tragacanth. Suppositories INDOCIN for rectal use contain 50 mg of indomethacin and the following inactive ingredients: butylated hydroxyanisole, butylated hydroxytoluene, edetic acid, glycerin, polyethylene glycol 3350, polyethylene glycol 8000 and sodium chloride. Indomethacin is a non-steroidal anti-inflammatory indole derivative designated chemically as 1-(4-chlorobenzoyl)-5- methoxy-2-methyl-1H-indole-3-acetic acid. Indomethacin is practically insoluble in water and sparingly soluble in alcohol. It has a pKa of 4.5 and is stable in neutral or slightly acidic media and decomposes in strong alkali. The suspension has a pH of 4.0-5.0. The structural formula is: * Registered trademark of MERCK & CO., Inc. COPYRIGHT © 1988, 2005 MERCK & CO., Inc.

Its mode of action, like that of other anti-inflammatory drugs, is not known. However, its therapeutic action is not due to pituitary-adrenal stimulation. INDOCIN is a potent inhibitor of prostaglandin synthesis in vitro. Concentrations are reached during therapy which have been demonstrated to have an effect in vivo as well. Prostaglandins sensitize afferent nerves and potentiate the action of bradykinin in inducing pain in animal models. Moreover, prostaglandins are known to be among the mediators of inflammation. Since indomethacin is an inhibitor of prostaglandin synthesis, its mode of action may be due to a decrease of prostaglandins in peripheral tissues. INDOCIN has been shown to be an effective anti-inflammatory agent, appropriate for long-term use in rheumatoid arthritis, ankylosing spondylitis, and osteoarthritis. INDOCIN affords relief of symptoms; it does not alter the progressive course of the underlying disease. INDOCIN suppresses inflammation in rheumatoid arthritis as demonstrated by relief of pain, and reduction of fever, swelling and tenderness. Improvement in patients treated with INDOCIN for rheumatoid arthritis has been demonstrated by a reduction in joint swelling, average number of joints involved, and morning stiffness; by increased mobility as demonstrated by a decrease in walking time; and by improved functional capability as demonstrated by an increase in grip strength. INDOCIN may enable the reduction of steroid dosage in patients receiving steroids for the more severe forms of rheumatoid arthritis. In such instances the steroid dosage should be reduced slowly and the patients followed very closely for any possible adverse effects. Indomethacin has been reported to diminish basal and CO2 stimulated cerebral blood flow in healthy volunteers following acute oral and intravenous administration. In one study after one week of treatment with orally administered indomethacin, this effect on basal cerebral blood flow had disappeared. The clinical significance of this effect has not been established. Capsules INDOCIN have been found effective in relieving the pain, reducing the fever, swelling, redness, and tenderness of acute gouty arthritis — see INDICATIONS AND USAGE. Following single oral doses of Capsules INDOCIN 25 mg or 50 mg, indomethacin is readily absorbed, attaining peak plasma concentrations of about 1 and 2 mcg/mL, respectively, at about 2 hours. Orally administered Capsules INDOCIN are virtually 100% bioavailable, with 90% of the dose absorbed within 4 hours. A single 50 mg dose of Oral Suspension INDOCIN was found to be bioequivalent to a 50 mg INDOCIN capsule when each was administered with food. Indomethacin is eliminated via renal excretion, metabolism, and biliary excretion. Indomethacin undergoes appreciable enterohepatic circulation. The mean half-life of indomethacin is estimated to be about 4.5 hours. With a typical therapeutic regimen of 25 or 50 mg t.i.d., the steady-state plasma concentrations of indomethacin are an average 1.4 times those following the first dose. The rate of absorption is more rapid from the rectal suppository than from Capsules INDOCIN. Ordinarily, therefore, the total amount absorbed from the suppository would be expected to be at least equivalent to the capsule. In controlled clinical trials, however, the amount of indomethacin absorbed was found to be somewhat less (80-90%) than that absorbed from Capsules INDOCIN. This is probably because some subjects did not retain the material from the suppository for the one hour necessary to assure complete absorption. Since the suppository dissolves rather quickly rather than melting slowly, it is seldom recovered in recognizable form if the patient retains the suppository for more than a few minutes. Indomethacin exists in the plasma as the parent drug and its desmethyl, desbenzoyl, and desmethyl- desbenzoyl metabolites, all in the unconjugated form. About 60 percent of an oral dosage is recovered This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda NDA 16-059/S-096, 17-814/S-039, 18-332/S-029 Page 5 in urine as drug and metabolites (26 percent as indomethacin and its glucuronide), and 33 percent is recovered in feces (1.5 percent as indomethacin). About 99% of indomethacin is bound to protein in plasma over the expected range of therapeutic plasma concentrations. Indomethacin has been found to cross the blood-brain barrier and the placenta. In a gastroscopic study in 45 healthy subjects, the number of gastric mucosal abnormalities was significantly higher in the group receiving Capsules INDOCIN than in the group taking Suppositories INDOCIN or placebo. In a double-blind comparative clinical study involving 175 patients with rheumatoid arthritis, however, the incidence of upper gastrointestinal adverse effects with Suppositories or Capsules INDOCIN was comparable. The incidence of lower gastrointestinal adverse effects was greater in the suppository group. INDICATIONS AND USAGE Carefully consider the potential benefits and risks of INDOCIN and other treatment options before deciding to use INDOCIN. Use the lowest effective dose for the shortest duration consistent with individual patient treatment goals (see WARNINGS). Indomethacin has been found effective in active stages of the following: 1. Moderate to severe rheumatoid arthritis including acute flares of chronic disease. 2. Moderate to severe ankylosing spondylitis. 3. Moderate to severe osteoarthritis. 4. Acute painful shoulder (bursitis and/or tendinitis). 5. Acute gouty arthritis. INDOCIN may enable the reduction of steroid dosage in patients receiving steroids for the more severe forms of rheumatoid arthritis. In such instances the steroid dosage should be reduced slowly and the patients followed very closely for any possible adverse effects. The use of INDOCIN in conjunction with aspirin or other salicylates is not recommended. Controlled clinical studies have shown that the combined use of INDOCIN and aspirin does not produce any greater therapeutic effect than the use of INDOCIN alone. Furthermore, in one of these clinical studies, the incidence of gastrointestinal side effects was significantly increased with combined therapy (see PRECAUTIONS, Drug Interactions). CONTRAINDICATIONS INDOCIN is contraindicated in patients with known hypersensitivity to indomethacin or the excipients (see DESCRIPTION). INDOCIN should not be given to patients who have experienced asthma, urticaria, or allergic-type reactions after taking aspirin or other NSAIDs. Severe, rarely fatal, anaphylactic/anaphylactoid reactions to NSAIDs have been reported in such patients (see WARNINGS, Anaphylactic/Anaphylactoid Reactions, and PRECAUTIONS, Preexisting Asthma). INDOCIN is contraindicated for the treatment of peri-operative pain in the setting of coronary artery bypass graft (CABG) surgery (see WARNINGS). Suppositories INDOCIN are contraindicated in patients with a history of proctitis or recent rectal bleeding. This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda NDA 16-059/S-096, 17-814/S-039, 18-332/S-029 Page 6 WARNINGS CARDIOVASCULAR EFFECTS Cardiovascular Thrombotic Events Clinical trials of several COX-2 selective and nonselective NSAIDs of up to three years duration have shown an increased risk of serious cardiovascular (CV) thrombotic events, myocardial infarction, and stroke, which can be fatal. All NSAIDs, both COX-2 selective and nonselective, may have a similar risk. Patients with known CV disease or risk factors for CV disease may be at greater risk. To minimize the potential risk for an adverse CV event in patients treated with an NSAID, the lowest effective dose should be used for the shortest duration possible. Physicians and patients should remain alert for the development of such events, even in the absence of previous CV symptoms. Patients should be informed about the signs and/or symptoms of serious CV events and the steps to take if they occur. There is no consistent evidence that concurrent use of aspirin mitigates the increased risk of serious CV thrombotic events associated with NSAID use. The concurrent use of aspirin and an NSAID does increase the risk of serious GI events (see GI WARNINGS). Two large, controlled, clinical trials of a COX-2 selective NSAID for the treatment of pain in the first 10-14 days following CABG surgery found an increased incidence of myocardial infarction and stroke (see CONTRAINDICATIONS). Hypertension NSAIDs, including INDOCIN, can lead to onset of new hypertension or worsening of pre-existing hypertension, either of which may contribute to the increased incidence of CV events. Patients taking thiazides or loop diuretics may have impaired response to these therapies when taking NSAIDs. NSAIDs, including INDOCIN, should be used with caution in patients with hypertension. Blood pressure (BP) should be monitored closely during the initiation of NSAID treatment and throughout the course of therapy. Congestive Heart Failure and Edema Fluid retention and edema have been observed in some patients taking NSAIDs. INDOCIN should be used with caution in patients with fluid retention or heart failure. In a study of patients with severe heart failure and hyponatremia, INDOCIN was associated with significant deterioration of circulatory hemodynamics, presumably due to inhibition of prostaglandin dependent compensatory mechanisms. Gastrointestinal Effects – Risk of Ulceration, Bleeding, and Perforation NSAIDs, including INDOCIN, can cause serious gastrointestinal (GI) adverse events including inflammation, bleeding, ulceration, and perforation of the esophagus, stomach, small intestine, or large intestine, which can be fatal. These serious adverse events can occur at any time, with or without warning symptoms, in patients treated with NSAIDs. Only one in five patients, who develop a serious upper GI adverse event on NSAID therapy is symptomatic. Upper GI ulcers, gross bleeding, or perforation caused by NSAIDs occur in approximately 1% of patients treated for 3-6 months, and in about 2-4% of patients treated for one year. These trends continue with longer duration of use, increasing the likelihood of developing a serious GI event at some time during the course of therapy. However, even short-term therapy is not without risk. This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda NDA 16-059/S-096, 17-814/S-039, 18-332/S-029 Page 7 Rarely, in patients taking INDOCIN, intestinal ulceration has been associated with stenosis and obstruction. Gastrointestinal bleeding without obvious ulcer formation and perforation of pre-existing sigmoid lesions (diverticulum, carcinoma, etc.) have occurred. Increased abdominal pain in ulcerative colitis patients or the development of ulcerative colitis and regional ileitis have been reported to occur rarely. NSAIDs should be prescribed with extreme caution in those with prior history of ulcer disease or gastrointestinal bleeding. Patients with a prior history of peptic ulcer disease and/or gastrointestinal bleeding who use NSAIDs have a greater than 10-fold increased risk for developing a GI bleed compared to patients with neither of these risk factors. Other factors that increase the risk for GI bleeding in patients treated with NSAIDs include concomitant use of oral corticosteroids or anticoagulants, longer duration of NSAID therapy, smoking, use of alcohol, older age, and poor general health status. Most spontaneous reports of fatal GI events are in elderly or debilitated patients and therefore, special care should be taken in treating this population. To minimize the potential risk for an adverse GI event in patients treated with an NSAID, the lowest effective dose should be used for the shortest possible duration. Patients and physicians should remain alert for signs and symptoms of GI ulceration and bleeding during NSAID therapy and promptly initiate additional evaluation and treatment if a serious GI adverse event is suspected. This should include discontinuation of the NSAID until a serious GI adverse event is ruled out. For high risk patients, alternate therapies that do not involve NSAIDs should be considered. Renal Effects Long-term administration of NSAIDs has resulted in renal papillary necrosis and other renal injury. Renal toxicity has also been seen in patients in whom renal prostaglandins have a compensatory role in the maintenance of renal perfusion. In these patients, administration of a nonsteroidal anti- inflammatory drug may cause a dose-dependent reduction in prostaglandin formation and, secondarily, in renal blood flow, which may precipitate over renal decompensation. Patients at greatest risk of this reaction are those with impaired renal function, heart failure, liver dysfunction, those taking diuretics and ACE inhibitors, patients with volume depletion, and the elderly. Discontinuation of NSAID therapy is usually followed by recovery to the pretreatment state. Caution should be used when initiating the treatment with INDOCIN in patients with considerable dehydration. It is advisable to rehydrate patients first and then start therapy with INDOCIN. Caution is also recommended in patients with preexisting kidney disease. Increases in serum potassium concentration, including hyperkalemia, have been reported with use of INDOCIN, even in some patients without renal impairment. In patients with normal renal function, these effects have been attributed to a hyporeninemic-hypoaldosteronism state (see PRECAUTIONS, Drug Interactions). Advanced Renal Disease No information is available from controlled clinical studies regarding the use of INDOCIN in patients with advanced renal disease. Therefore, treatment with INDOCIN is not recommended in these patients with advanced renal disease. If INDOCIN therapy must be initiated, close monitoring of the patient’s renal function is advisable. Since INDOCIN is eliminated primarily by the kidneys, patients with significantly impaired renal function should be closely monitored; a lower daily dosage should be anticipated to avoid excessive drug accumulation. This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda NDA 16-059/S-096, 17-814/S-039, 18-332/S-029 Page 8 Anaphylactic/Anaphylactoid Reactions As with other NSAIDs, anaphylactic/anaphylactoid reactions may occur in patients without known prior exposure to INDOCIN. INDOCIN should not be given to patients with the aspirin triad. This symptom complex typically occurs in asthmatic patients who experience rhinitis with or without nasal polyps, or who exhibit severe, potentially fatal bronchospasm after taking aspirin or other NSAIDs (see CONTRAINDICATIONS and PRECAUTIONS – Preexisting Asthma). Emergency help should be sought in cases where an anaphylactic/anaphylactoid reaction occurs. Skin Reactions NSAIDs, including INDOCIN, can cause serious skin adverse events such as exfoliative dermatitis, Stevens-Johnson Syndrome (SJS), and toxic epidermal necrolysis (TEN), which can be fatal. These serious events may occur without warning. Patients should be informed about the signs and symptoms of serious skin manifestations and use of the drug should be discontinued at the first appearance of skin rash or any other sign of hypersensitivity. Pregnancy Teratogenic Effects. Pregnancy Category C. INDOCIN is not recommended for use in pregnant women, since safety for use has not been established. Teratogenic studies were conducted in mice and rats at dosages of 0.5, 1.0, 2.0, and 4.0 mg/kg/day. Except for retarded fetal ossification at 4 mg/kg/day considered secondary to the decreased average fetal weights, no increase in fetal malformations was observed as compared with control groups. Other studies in mice reported in the literature using higher doses (5 to 15 mg/kg/day) have described maternal toxicity and death, increased fetal resorptions, and fetal malformations. Comparable studies in rodents using high doses of aspirin have shown similar maternal and fetal effects. However, animal reproduction studies are not always predictive of human response. There are no adequate and well-controlled studies in pregnant women. Nonteratogenic Effects Because of the known effects of nonsteroidal anti-inflammatory drugs on the fetal cardiovascular system (closure of ductus arteriosus), use during pregnancy (particularly late pregnancy) should be avoided. The known effects of indomethacin and other drugs of this class on the human fetus during the third trimester of pregnancy include: constriction of the ductus arteriosus prenatally, tricuspid incompetence, and pulmonary hypertension; non-closure of the ductus arteriosus postnatally which may be resistant to medical management; myocardial degenerative changes, platelet dysfunction with resultant bleeding, intracranial bleeding, renal dysfunction or failure, renal injury/dysgenesis which may result in prolonged or permanent renal failure, oligohydramnios, gastrointestinal bleeding or perforation, and increased risk of necrotizing enterocolitis. In rats and mice, 4.0 mg/kg/day given during the last three days of gestation caused a decrease in maternal weight gain and some maternal and fetal deaths. An increased incidence of neuronal necrosis in the diencephalon in the live-born fetuses was observed. At 2.0 mg/kg/day, no increase in neuronal necrosis was observed as compared to the control groups. Administration of 0.5 or 4.0 mg/kg/day during the first three days of life did not cause an increase in neuronal necrosis at either dose level. This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda NDA 16-059/S-096, 17-814/S-039, 18-332/S-029 Page 9 Labor and Delivery In rat studies with NSAIDs, as with other drugs known to inhibit prostaglandin synthesis, an increased incidence of dystocia, delayed parturition, and decreased pup survival occurred. The effects of INDOCIN on labor and delivery in pregnant women are unknown. Use in Nursing Mothers INDOCIN is excreted in the milk of lactating mothers. INDOCIN is not recommended for use in nursing mothers. Pregnancy In late pregnancy, as with other NSAIDs, INDOCIN should be avoided because it may cause premature closure of the ductus arteriosus. Ocular Effects: Corneal deposits and retinal disturbances, including those of the macula, have been observed in some patients who had received prolonged therapy with INDOCIN. The prescribing physician should be alert to the possible association between the changes noted and INDOCIN. It is advisable to discontinue therapy if such changes are observed. Blurred vision may be a significant symptom and warrants a thorough ophthalmological examination. Since these changes may be asymptomatic, ophthalmologic examination at periodic intervals is desirable in patients where therapy is prolonged. Central Nervous System Effects: INDOCIN may aggravate depression or other psychiatric disturbances, epilepsy, and parkinsonism, and should be used with considerable caution in patients with these conditions. If severe CNS adverse reactions develop, INDOCIN should be discontinued. INDOCIN may cause drowsiness; therefore, patients should be cautioned about engaging in activities requiring mental alertness and motor coordination, such as driving a car. INDOCIN may also cause headache. Headache which persists despite dosage reduction requires cessation of therapy with INDOCIN. PRECAUTIONS General INDOCIN cannot be expected to substitute for corticosteroids or to treat corticosteroid insufficiency. Abrupt discontinuation of corticosteroids may lead to disease exacerbation. Patients on prolonged corticosteroid therapy should have their therapy tapered slowly if a decision is made to discontinue corticosteroids. The pharmacological activity of INDOCIN in reducing fever and inflammation may diminish the utility of these diagnostic signs in detecting complications of presumed noninfectious, painful conditions. Hepatic Effects Borderline elevations of one or more liver tests may occur in up to 15% of patients taking NSAIDs including INDOCIN. These laboratory abnormalities may progress, may remain unchanged, or may be transient with continuing therapy. Notable elevations of ALT or AST (approximately three or more times the upper limit of normal) have been reported in approximately 1% of patients in clinical trials with NSAIDs. In addition, rare cases of severe hepatic reactions, including jaundice and fatal fulminant hepatitis, liver necrosis and hepatic failure, some of them with fatal outcomes have been reported. This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda NDA 16-059/S-096, 17-814/S-039, 18-332/S-029 Page 10 A patient with symptoms and/or signs suggesting liver dysfunction, or in whom an abnormal liver test has occurred, should be evaluated for evidence of the development of a more severe hepatic reaction while on therapy with INDOCIN. If clinical signs and symptoms consistent with liver disease develop, or if systemic manifestations occur (e.g., eosinophilia, rash, etc.), INDOCIN should be discontinued. Hematological Effects Anemia is sometimes seen in patients receiving NSAIDs, including INDOCIN. This may be due to fluid retention, occult or gross GI blood loss, or an incompletely described effect upon erythropoiesis. Patients on long-term treatment with NSAIDs, including INDOCIN, should have their hemoglobin or hematocrit checked if they exhibit any signs or symptoms of anemia. NSAIDs inhibit platelet aggregation and have been shown to prolong bleeding time in some patients. Unlike aspirin, their effect on platelet function is quantitatively less, of shorter duration, and reversible. Patients receiving INDOCIN who may be adversely affected by alterations in platelet function, such as those with coagulation disorders or patients receiving anticoagulants, should be carefully monitored. Preexisting Asthma Patients with asthma may have aspirin-sensitive asthma. The use of aspirin in patients with aspirin- sensitive asthma has been associated with severe bronchospasm which can be fatal. Since cross reactivity, including bronchospasm, between aspirin and other nonsteroidal anti-inflammatory drugs has been reported in such aspirin-sensitive patients, INDOCIN should not be administered to patients with this form of aspirin sensitivity and should be used with caution in patients with preexisting asthma. Information for Patients Patients should be informed of the following information before initiating therapy with an NSAID and periodically during the course of ongoing therapy. Patients should also be encouraged to read the NSAID Medication Guide that accompanies each prescription dispensed. 1. INDOCIN, like other NSAIDs, may cause serious CV side effects, such as MI or stroke, which may result in hospitalization and even death. Although serious CV events can occur without warning symptoms, patients should be alert for the signs and symptoms of chest pain, shortness of breath, weakness, slurring of speech, and should ask for medical advice when observing any indicative sign or symptoms. Patients should be apprised of the importance of this follow-up (see WARNINGS, CARDIOVASCULAR EFFECTS). 2. INDOCIN, like other NSAIDs, can cause GI discomfort and, rarely, serious GI side effects, such as ulcers and bleeding, which may result in hospitalization and even death. Although serious GI tract ulcerations and bleeding can occur without warning symptoms, patients should be alert for the signs and symptoms of ulcerations and bleeding, and should ask for medical advice when observing any indicative sign or symptoms including epigastric pain, dyspepsia, melena, and hematemesis. Patients should be apprised of the importance of this follow-up (see WARNINGS, Gastrointestinal Effects - Risk of Ulceration, Bleeding, and Perforation). 3. INDOCIN, like other NSAIDs, can cause serious skin side effects such as exfoliative dermatitis, SJS, and TEN, which may result in hospitalizations and even death. Although serious skin This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda NDA 16-059/S-096, 17-814/S-039, 18-332/S-029 Page 11 reactions may occur without warning, patients should be alert for the signs and symptoms of skin rash and blisters, fever, or other signs of hypersensitivity such as itching, and should ask for medical advice when observing any indicative signs or symptoms. Patients should be advised to stop the drug immediately if they develop any type of rash and contact their physicians as soon as possible. 4. Patients should promptly report signs or symptoms of unexplained weight gain or edema to their physicians. 5. Patients should be informed of the warning signs and symptoms of hepatotoxicity (e.g., nausea, fatigue, lethargy, pruritus, jaundice, right upper quadrant tenderness, and “flu-like” symptoms). If these occur, patients should be instructed to stop therapy and seek immediate medical therapy. 6. Patients should be informed of the signs of an anaphylactic/anaphylactoid reaction (e.g. difficulty breathing, swelling of the face or throat). If these occur, patients should be instructed to seek immediate emergency help (see WARNINGS). 7. In late pregnancy, as with other NSAIDs, INDOCIN should be avoided because it may cause premature closure of the ductus arteriosus. Laboratory Tests Because serious GI tract ulcerations and bleeding can occur without warning symptoms, physicians should monitor for signs or symptoms of GI bleeding. Patients on long-term treatment with NSAIDs should have their CBC and a chemistry profile checked periodically. If clinical signs and symptoms consistent with liver or renal disease develop, systemic manifestations occur (e.g., eosinophilia, rash, etc.) or if abnormal liver tests persist or worsen, INDOCIN should be discontinued. Drug Interactions ACE-Inhibitors and Angiotensin II Antagonists Reports suggest that NSAIDs may diminish the antihypertensive effect of ACE-inhibitors and angiotensin II antagonists. INDOCIN can reduce the antihypertensive effects of captopril and losartan. These interactions should be given consideration in patients taking NSAIDs concomitantly with ACE- inhibitors or angiotensin II antagonists. In some patients with compromised renal function, the co- administration of an NSAID and an ACE-inhibitor or an angiotensin II antagonist may result in further deterioration of renal function, including possible acute renal failure, which is usually reversible. Aspirin When INDOCIN is administered with aspirin, its protein binding is reduced, although the clearance of free INDOCIN is not altered. The clinical significance of this interaction is not known. The use of INDOCIN in conjunction with aspirin or other salicylates is not recommended. Controlled clinical studies have shown that the combined use of INDOCIN and aspirin does not produce any greater therapeutic effect than the use of INDOCIN alone. In a clinical study of the combined use of INDOCIN and aspririn, the incidence of gastrointestinal side effects was significantly increased with combined therapy.; however, as with other NSAIDs, concomitant administration of indomethacin and aspirin is not generally recommended because of the potential of increased adverse effects. This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda NDA 16-059/S-096, 17-814/S-039, 18-332/S-029 Page 12 In a study in normal volunteers, it was found that chronic concurrent administration of 3.6 g of aspirin per day decreases indomethacin blood levels approximately 20%. Beta-adrenoceptor blocking agents Blunting of the antihypertensive effect of beta-adrenoceptor blocking agents by non-steroidal anti- inflammatory drugs including INDOCIN has been reported. Therefore, when using these blocking agents to treat hypertension, patients should be observed carefully in order to confirm that the desired therapeutic effect has been obtained. Cyclosporine Administration of non-steroidal anti-inflammatory drugs concomitantly with cyclosporine has been associated with an increase in cyclosporine-induced toxicity, possibly due to decreased synthesis of renal prostacyclin. NSAIDs should be used with caution in patients taking cyclosporine, and renal function should be carefully monitored. Diflunisal In normal volunteers receiving indomethacin, the administration of diflunisal decreased the renal clearance and significantly increased the plasma levels of indomethacin. In some patients, combined use of INDOCIN and diflunisal has been associated with fatal gastrointestinal hemorrhage. Therefore, diflunisal and INDOCIN should not be used concomitantly. Digoxin INDOCIN given concomitantly with digoxin has been reported to increase the serum concentration and prolong the half-life of digoxin. Therefore, when INDOCIN and digoxin are used concomitantly, serum digoxin levels should be closely monitored. Diuretics In some patients, the administration of INDOCIN can reduce the diuretic, natriuretic, and antihypertensive effects of loop, potassium-sparing, and thiazide diuretics. This response has been attributed to inhibition of renal prostaglandin synthesis. INDOCIN reduces basal plasma renin activity (PRA), as well as those elevations of PRA induced by furosemide administration, or salt or volume depletion. These facts should be considered when evaluating plasma renin activity in hypertensive patients. It has been reported that the addition of triamterene to a maintenance schedule of INDOCIN resulted in reversible acute renal failure in two of four healthy volunteers. INDOCIN and triamterene should not be administered together. INDOCIN and potassium-sparing diuretics each may be associated with increased serum potassium levels. The potential effects of INDOCIN and potassium-sparing diuretics on potassium kinetics and renal function should be considered when these agents are administered concurrently. Most of the above effects concerning diuretics have been attributed, at least in part, to mechanisms involving inhibition of prostaglandin synthesis by INDOCIN. During concomitant therapy with NSAIDs, the patient should be observed closely for signs of renal failure (see WARNINGS, Renal Effects), as well as to assure diuretic efficacy. Lithium NSAIDs have produced an elevation of plasma lithium levels and a reduction in renal lithium clearance. The mean minimum lithium concentration increased 15% and the renal clearance was decreased by approximately 20%. This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda NDA 16-059/S-096, 17-814/S-039, 18-332/S-029 Page 13 Capsules INDOCIN 50 mg t.i.d. produced a clinically relevant elevation of plasma lithium and reduction in renal lithium clearance in psychiatric patients and normal subjects with steady state plasma lithium concentrations. This effect has been attributed to inhibition of prostaglandin synthesis. As a consequence, when NSAIDs and lithium are given concomitantly, the patient should be carefully observed for signs of lithium toxicity. (Read circulars for lithium preparations before use of such concomitant therapy.) In addition, the frequency of monitoring serum lithium concentration should be increased at the outset of such combination drug treatment. Methotrexate NSAIDs have been reported to competitively inhibit methotrexate accumulation in rabbit kidney slices. This may indicate that they could enhance the toxicity of methotrexate. Caution should be used when NSAIDs are administered concomitantly with methotrexate. NSAIDs The concomitant use of INDOCIN with other NSAIDs is not recommended due to the increased possibility of gastrointestinal toxicity, with little or no increase in efficacy. Oral anticoagulants Clinical studies have shown that INDOCIN does not influence the hypoprothrombinemia produced by anticoagulants. However, when any additional drug, including INDOCIN, is added to the treatment of patients on anticoagulant therapy, the patients should be observed for alterations of the prothrombin time. In post-marketing experience, bleeding has been reported in patients on concomitant treatment with anticoagulants and INDOCIN. Caution should be exercised when INDOCIN and anticoagulants are administered concomitantly. The effects of warfarin and NSAIDs on GI bleeding are synergistic, such that users of both drugs together have a risk of serious GI bleeding higher than users of either drug alone. Probenecid When INDOCIN is given to patients receiving probenecid, the plasma levels of indomethacin are likely to be increased. Therefore, a lower total daily dosage of INDOCIN may produce a satisfactory therapeutic effect. When increases in the dose of INDOCIN are made, they should be made carefully and in small increments. Drug/Laboratory Test Interactions False-negative results in the dexamethasone suppression test (DST) in patients being treated with INDOCIN have been reported. Thus, results of the DST should be interpreted with caution in these patients. Carcinogenesis, Mutagenesis, Impairment of Fertility In an 81-week chronic oral toxicity study in the rat at doses up to 1 mg/kg/day, indomethacin had no tumorigenic effect. Indomethacin produced no neoplastic or hyperplastic changes related to treatment in carcinogenic studies in the rat (dosing period 73-110 weeks) and the mouse (dosing period 62-88 weeks) at doses up to 1.5 mg/kg/day. Indomethacin did not have any mutagenic effect in in vitro bacterial tests (Ames test and E. coli with or without metabolic activation) and a series of in vivo tests including the host-mediated assay, sex-linked recessive lethals in Drosophila, and the micronucleus test in mice. Indomethacin at dosage levels up to 0.5 mg/kg/day had no effect on fertility in mice in a two generation reproduction study or a two litter reproduction study in rats. This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda NDA 16-059/S-096, 17-814/S-039, 18-332/S-029 Page 14 Pregnancy Teratogenic Effects. Pregnancy Category C. Teratogenic studies were conducted in mice and rats at dosages of 0.5, 1.0, 2.0, and 4.0 mg/kg/day. Except for retarded fetal ossification at 4 mg/kg/day considered secondary to the decreased average fetal weights, no increase in fetal malformations was observed as compared with control groups. Other studies in mice reported in the literature using higher doses (5 to 15 mg/kg/day) have described maternal toxicity and death, increased fetal resorptions, and fetal malformations. Comparable studies in rodents using high doses of aspirin have shown similar maternal and fetal effects. However, animal reproduction studies are not always predictive of human response. There are no adequate and well- controlled studies in pregnant women. INDOCIN should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus. Nonteratogenic Effects Because of the known effects of nonsteroidal anti-inflammatory drugs on the fetal cardiovascular system (closure of ductus arteriosus), use during pregnancy (particularly late pregnancy) should be avoided. The known effects of indomethacin and other drugs of this class on the human fetus during the third trimester of pregnancy include: constriction of the ductus arteriosus prenatally, tricuspid incompetence, and pulmonary hypertension; non-closure of the ductus arteriosus postnatally which may be resistant to medical management; myocardial degenerative changes, platelet dysfunction with resultant bleeding, intracranial bleeding, renal dysfunction or failure, renal injury/dysgenesis which may result in prolonged or permanent renal failure, oligohydramnios, gastrointestinal bleeding or perforation, and increased risk of necrotizing enterocolitis. In rats and mice, 4.0 mg/kg/day given during the last three days of gestation caused a decrease in maternal weight gain and some maternal and fetal deaths. An increased incidence of neuronal necrosis in the diencephalon in the live-born fetuses was observed. At 2.0 mg/kg/day, no increase in neuronal necrosis was observed as compared to the control groups. Administration of 0.5 or 4.0 mg/kg/day during the first three days of life did not cause an increase in neuronal necrosis at either dose level. Labor and Delivery In rat studies with NSAIDs, as with other drugs known to inhibit prostaglandin synthesis, an increased incidence of dystocia, delayed parturition, and decreased pup survival occurred. The effects of INDOCIN on labor and delivery in pregnant women are unknown. Use in Nursing Mothers INDOCIN is excreted in the milk of lactating mothers. INDOCIN is not recommended for use in nursing mothers. Pediatric Use Safety and effectiveness in pediatric patients 14 years of age and younger has not been established. INDOCIN should not be prescribed for pediatric patients 14 years of age and younger unless toxicity or lack of efficacy associated with other drugs warrants the risk. In experience with more than 900 pediatric patients reported in the literature or to the manufacturer who were treated with Capsules INDOCIN, side effects in pediatric patients were comparable to those reported in adults. Experience in pediatric patients has been confined to the use of Capsules INDOCIN. If a decision is made to use indomethacin for pediatric patients two years of age or older, such patients should be monitored closely and periodic assessment of liver function is recommended. There have been cases of hepatotoxicity reported in pediatric patients with juvenile rheumatoid arthritis, This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda NDA 16-059/S-096, 17-814/S-039, 18-332/S-029 Page 15 including fatalities. If indomethacin treatment is instituted, a suggested starting dose is 2 1 mg/kg/day given in divided doses. Maximum daily dosage should not exceed 4 mg/kg/day or 150-200 mg/day, whichever is less. As symptoms subside, the total daily dosage should be reduced to the lowest level required to control symptoms, or the drug should be discontinued. Geriatric Use As with any NSAID, caution should be exercised in treating the elderly (65 years and older) since advancing age appears to increase the possibility of adverse reactions (see WARNINGS, Gastrointestinal Effects - Risk of Ulceration, Bleeding, and Perforation and DOSAGE AND ADMINISTRATION). Elderly patients seem to tolerate ulceration or bleeding less well than other individuals and many spontaneous reports of fatal GI events are in this population (see WARNINGS, Gastrointestinal Effects - Risk of Ulceration, Bleeding, and Perforation). Indomethacin may cause confusion or, rarely, psychosis (see ADVERSE REACTIONS); physicians should remain alert to the possibility of such adverse effects in the elderly. This drug is known to be substantially excreted by the kidney and the risk of toxic reactions to this drug may be greater in patients with impaired renal function. Because elderly patients are more likely to have decreased renal function, care should be taken in dose selection and it may be useful to monitor renal function (see WARNINGS, Renal Effects). ADVERSE REACTIONS In a gastroscopic study in 45 healthy subjects, the number of gastric mucosal abnormalities was significantly higher in the group receiving Capsules INDOCIN than in the group taking Suppositories INDOCIN or placebo. In a double-blind comparative clinical study involving 175 patients with rheumatoid arthritis, however, the incidence of upper gastrointestinal adverse effects with Suppositories or Capsules INDOCIN was comparable. The incidence of lower gastrointestinal adverse effects was greater in the suppository group. The adverse reactions for Capsules INDOCIN listed in the following table have been arranged into two groups: (1) incidence greater than 1%; and (2) incidence less than 1%. The incidence for group (1) was obtained from 33 double-blind controlled clinical trials reported in the literature (1,092 patients). The incidence for group (2) was based on reports in clinical trials, in the literature, and on voluntary reports since marketing. The probability of a causal relationship exists between INDOCIN and these adverse reactions, some of which have been reported only rarely. The adverse reactions reported with Capsules INDOCIN may occur with use of the suppositories. In addition, rectal irritation and tenesmus have been reported in patients who have received the suppositories. The adverse reactions reported with Capsules INDOCIN may also occur with use of the suspension. This label may not be the latest approved by FDA.

Causal relationship unknown: Other reactions have been reported but occurred under circumstances where a causal relationship could not be established. However, in these rarely reported events, the possibility cannot be excluded. Therefore, these observations are being listed to serve as alerting information to physicians: Cardiovascular: Thrombophlebitis Hematologic: Although there have been several reports of leukemia, the supporting information is weak Genitourinary: Urinary frequency. A rare occurrence of fulminant necrotizing fasciitis, particularly in association with Group A β hemolytic streptococcus, has been described in persons treated with non-steroidal anti-inflammatory agents, including indomethacin, sometimes with fatal outcome (see also PRECAUTIONS, General). This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda NDA 16-059/S-096, 17-814/S-039, 18-332/S-029 Page 18 OVERDOSAGE The following symptoms may be observed following overdosage: nausea, vomiting, intense headache, dizziness, mental confusion, disorientation, or lethargy. There have been reports of paresthesias, numbness, and convulsions. Treatment is symptomatic and supportive. The stomach should be emptied as quickly as possible if the ingestion is recent. If vomiting has not occurred spontaneously, the patient should be induced to vomit with syrup of ipecac. If the patient is unable to vomit, gastric lavage should be performed. Once the stomach has been emptied, 25 or 50 g of activated charcoal may be given. Depending on the condition of the patient, close medical observation and nursing care may be required. The patient should be followed for several days because gastrointestinal ulceration and hemorrhage have been reported as adverse reactions of indomethacin. Use of antacids may be helpful. The oral LD50 of indomethacin in mice and rats (based on 14 day mortality response) was 50 and 12 mg/kg, respectively. DOSAGE AND ADMINISTRATION Carefully consider the potential benefits and risks of INDOCIN and other treatment options before deciding to use INDOCIN. Use the lowest effective dose for the shortest duration consistent with individual patient treatment goals (see WARNINGS). After observing the response to initial therapy with INDOCIN, the dose and frequency should be adjusted to suit an individual patient’s needs. INDOCIN is available as 25 and 50 mg Capsules INDOCIN, Oral Suspension INDOCIN, containing 25 mg of indomethacin per 5 mL, and 50 mg Suppositories INDOCIN for rectal use. Adverse reactions appear to correlate with the size of the dose of INDOCIN in most patients but not all. Therefore, every effort should be made to determine the smallest effective dosage for the individual patient. Always give Capsules INDOCIN or Oral Suspension INDOCIN with food, immediately after meals, or with antacids to reduce gastric irritation. Pediatric Use INDOCIN ordinarily should not be prescribed for pediatric patients 14 years of age and under (see PRECAUTIONS, Pediatric Use). Adult Use Dosage Recommendations for Active Stages of the Following: 1. Moderate to severe rheumatoid arthritis including acute flares of chronic disease; moderate to severe ankylosing spondylitis; and moderate to severe osteoarthritis. Suggested Dosage: Capsules INDOCIN 25 mg b.i.d. or t.i.d. If this is well tolerated, increase the daily dosage by 25 or by 50 mg, if required by continuing symptoms, at weekly intervals until a satisfactory response is obtained or until a total daily dose of 150-200 mg is reached. DOSES ABOVE THIS AMOUNT GENERALLY DO NOT INCREASE THE EFFECTIVENESS OF THE DRUG. In patients who have persistent night pain and/or morning stiffness, the giving of a large portion, up to a maximum of 100 mg, of the total daily dose at bedtime, either orally or by rectal suppositories, may be helpful in affording relief. The total daily dose should not exceed 200 mg. In acute flares of chronic rheumatoid arthritis, it may be necessary to increase the dosage by 25 mg or, if required, by 50 mg daily. If minor adverse effects develop as the dosage is increased, reduce the dosage rapidly to a tolerated dose and OBSERVE THE PATIENT CLOSELY. This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda NDA 16-059/S-096, 17-814/S-039, 18-332/S-029 Page 19 If severe adverse reactions occur, STOP THE DRUG. After the acute phase of the disease is under control, an attempt to reduce the daily dose should be made repeatedly until the patient is receiving the smallest effective dose or the drug is discontinued. Careful instructions to, and observations of, the individual patient are essential to the prevention of serious, irreversible, including fatal, adverse reactions. As advancing years appear to increase the possibility of adverse reactions, INDOCIN should be used with greater care in the elderly (see PRECAUTIONS, Geriatric Use). 2. Acute painful shoulder (bursitis and/or tendinitis). Initial Dose: 75-150 mg daily in 3 or 4 divided doses. The drug should be discontinued after the signs and symptoms of inflammation have been controlled for several days. The usual course of therapy is 7-14 days. 3. Acute gouty arthritis. Suggested Dosage: Capsules INDOCIN 50 mg t.i.d. until pain is tolerable. The dose should then be rapidly reduced to complete cessation of the drug. Definite relief of pain has been reported within 2 to 4 hours. Tenderness and heat usually subside in 24 to 36 hours, and swelling gradually disappears in 3 to 5 days.

What is the most important information I should know about medicines called Non- Steroidal Anti-Inflammatory Drugs (NSAIDs)? NSAID medicines may increase the chance of a heart attack or stroke that can lead to death. This chance increases: • with longer use of NSAID medicines • in people who have heart disease NSAID medicines should never be used right before or after a heart surgery called a “coronary artery bypass graft (CABG).” NSAID medicines can cause ulcers and bleeding in the stomach and intestines at any time during treatment. Ulcers and bleeding: • can happen without warning symptoms • may cause death The chance of a person getting an ulcer or bleeding increases with: • taking medicines called “corticosteroids” and “anticoagulants” • longer use • smoking • drinking alcohol • older age • having poor health NSAID medicines should only be used: • exactly as prescribed • at the lowest dose possible for your treatment • for the shortest time needed This label may not be the latest approved by FDA.

NSAID medicines are used to treat pain and redness, swelling, and heat (inflammation) from medical conditions such as: • different types of arthritis • menstrual cramps and other types of short-term pain Who should not take a Non-Steroidal Anti-Inflammatory Drug (NSAID)? Do not take an NSAID medicine: • if you had an asthma attack, hives, or other allergic reaction with aspirin or any other NSAID medicine • for pain right before or after heart bypass surgery Tell your healthcare provider: • about all your medical conditions. • about all of the medicines you take. NSAIDs and some other medicines can interact with each other and cause serious side effects. Keep a list of your medicines to show to your healthcare provider and pharmacist. • if you are pregnant. NSAID medicines should not be used by pregnant women late in their pregnancy. • if you are breastfeeding. Talk to your doctor. What are the possible side effects of Non-Steroidal Anti-Inflammatory Drugs (NSAIDs)? Serious side effects include: • heart attack • stroke • high blood pressure • heart failure from body swelling (fluid retention) • kidney problems including kidney failure • bleeding and ulcers in the stomach and intestine • low red blood cells (anemia) • life-threatening skin reactions • life-threatening allergic reactions • liver problems including liver failure • asthma attacks in people who have asthma Other side effects include: • stomach pain • constipation • diarrhea • gas • heartburn • nausea • vomiting • dizziness Get emergency help right away if you have any of the following symptoms: • shortness of breath or trouble breathing • slurred speech • chest pain • swelling of the face or throat • weakness in one part or side of your body This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda NDA 16-059/S-096, 17-814/S-039, 18-332/S-029 Page 22 Stop your NSAID medicine and call your healthcare provider right away if you have any of the following symptoms: • nausea • more tired or weaker than usual • itching • your skin or eyes look yellow • stomach pain • flu-like symptoms • vomit blood • there is blood in your bowel movement or it is black and sticky like tar • unusual weight gain • skin rash or blisters with fever • swelling of the arms and legs, hands and feet These are not all the side effects with NSAID medicines. Talk to your healthcare provider or pharmacist for more information about NSAID medicines. Other information about Non-Steroidal Anti-Inflammatory Drugs (NSAIDs) • Aspirin is an NSAID medicine but it does not increase the chance of a heart attack. Aspirin can cause bleeding in the brain, stomach, and intestines. Aspirin can also cause ulcers in the stomach and intestines. • Some of these NSAID medicines are sold in lower doses without a prescription (over-the-counter). Talk to your healthcare provider before using over-the-counter NSAIDs for more than 10 days.

HIGHLIGHTS OF PRESCRIBING INFORMATION These highlights do not include all the information needed to use INDOCIN® SUPPOSITORIES safely and effectively. See full prescribing information for INDOCIN. INDOCIN (indomethacin) Suppositories, for rectal use Initial U.S. Approval: 1965 WARNING: RISK OF SERIOUS CARDIOVASCULAR AND GASTROINTESTINAL EVENTS See full prescribing information for complete boxed warning.  Nonsteroidal anti-inflammatory drugs (NSAIDs) cause an increased risk of serious cardiovascular thrombotic events, including myocardial infarction and stroke, which can be fatal. This risk may occur early in treatment and may increase with duration of use (5.1)  INDOCIN is contraindicated in the setting of coronary artery bypass graft (CABG) surgery (4, 5.1)  NSAIDs cause an increased risk of serious gastrointestinal (GI) adverse events including bleeding, ulceration, and perforation of the stomach or intestines, which can be fatal. These events can occur at any time during use and without warning symptoms. Elderly patients and patients with a prior history of peptic ulcer disease and/or GI bleeding are at greater risk for serious GI events (5.2) RECENT MAJOR CHANGES Boxed Warning 5/2016 Warnings and Precautions, Cardiovascular Thrombotic Events (5.1) 5/2016 Warnings and Precautions, Heart Failure and Edema (5.5) 5/2016 INDICATIONS AND USAGE INDOCIN is a nonsteroidal anti-inflammatory drug indicated for:  Moderate to severe rheumatoid arthritis including acute flares of chronic disease  Moderate to severe ankylosing spondylitis  Moderate to severe osteoarthritis  Acute painful shoulder (bursitis and/or tendinitis)  Acute gouty arthritis (1) DOSAGE AND ADMINISTRATION  Use the lowest effective dosage for shortest duration consistent with individual patient treatment goals (2.1)  INDOCIN suppositories 50 mg can be substituted for indomethacin capsules, USP; however, there will be significant differences between the two dosage regimens in indomethacin blood levels (12.3)  The dosage for moderate to severe rheumatoid arthritis including acute flares of chronic disease; moderate to severe ankylosing spondylitis; and moderate to severe osteoarthritis is indomethacin capsules, USP 25 mg two or three times a day (2.3)  The dosage for acute painful shoulder (bursitis and/or tendinitis) is indomethacin capsules, USP 75-150 mg daily in 3 or 4 divided doses (2.4)  The dosage for acute gouty arthritis is indomethacin capsules, USP 50 mg three times a day (2.5)  INDOCIN Suppositories are not for oral or intravaginal use DOSAGE FORMS AND STRENGTHS INDOCIN (indomethacin) Suppositories: 50 mg (3) CONTRAINDICATIONS  Known hypersensitivity to indomethacin or any components of the drug product (4)  History of asthma, urticaria, or other allergic-type reactions after taking aspirin or other NSAIDs (4)  In the setting of CABG surgery (4)  In patients with a history of proctitis or recent rectal bleeding (4) WARNINGS AND PRECAUTIONS  Hepatotoxicity: Inform patients of warning signs and symptoms of hepatotoxicity. Discontinue if abnormal liver tests persist or worsen or if clinical signs and symptoms of liver disease develop (5.3)  Hypertension: Patients taking some antihypertensive medications may have impaired response to these therapies when taking NSAIDs. Monitor blood pressure (5.4, 7)  Heart Failure and Edema: Avoid use of INDOCIN in patients with severe heart failure unless benefits are expected to outweigh risk of worsening heart failure (5.5)  Renal Toxicity: Monitor renal function in patients with renal or hepatic impairment, heart failure, dehydration, or hypovolemia. Avoid use of INDOCIN in patients with advanced renal disease unless benefits are expected to outweigh risk of worsening renal function (5.6)  Anaphylactic Reactions: Seek emergency help if an anaphylactic reaction occurs (5.7)  Exacerbation of Asthma Related to Aspirin Sensitivity: INDOCIN is contraindicated in patients with aspirin-sensitive asthma. Monitor patients with preexisting asthma (without aspirin sensitivity) (5.8)  Serious Skin Reactions: Discontinue INDOCIN at first appearance of skin rash or other signs of hypersensitivity (5.9)  Premature Closure of Fetal Ductus Arteriosus: Avoid use in pregnant women starting at 30 weeks gestation (5.10, 8.1)  Hematologic Toxicity: Monitor hemoglobin or hematocrit in patients with any signs or symptoms of anemia (5.11, 7) ADVERSE REACTIONS Most common adverse reactions (incidence ≥ 3%) are headache, dizziness, dyspepsia, and nausea. (6) To report SUSPECTED ADVERSE REACTIONS, contact Iroko Pharmaceuticals, LLC at 1-877-757-0676 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch. DRUG INTERACTIONS  Drugs that Interfere with Hemostasis (e.g. warfarin, aspirin, SSRIs/SNRIs): Monitor patients for bleeding who are concomitantly taking INDOCIN with drugs that interfere with hemostasis. Concomitant use of INDOCIN and analgesic doses of aspirin is not generally recommended (7)  ACE Inhibitors, Angiotensin Receptor Blockers (ARB), or Beta-Blockers: Concomitant use with INDOCIN may diminish the antihypertensive effect of these drugs. Monitor blood pressure (7)  ACE Inhibitors and ARBs: Concomitant use with INDOCIN in elderly, volume depleted, or those with renal impairment may result in deterioration of renal function. In such high risk patients, monitor for signs of worsening renal function (7)  Diuretics: NSAIDs can reduce natriuretic effect of furosemide and thiazide diuretics. Monitor patients to assure diuretic efficacy including antihypertensive effects (7)  Digoxin: Concomitant use with INDOCIN can increase serum concentration and prolong half-life of digoxin. Monitor serum digoxin levels (7) USE IN SPECIFIC POPULATIONS Pregnancy: Use of NSAIDs during the third trimester of pregnancy increases the risk of premature closure of the fetal ductus arteriosus. Avoid use of NSAIDs in pregnant women starting at 30 weeks gestation (5.10, 8.1) Infertility: NSAIDs are associated with reversible infertility.

For current labeling information, please visit https://www.fda.gov/drugsatfda FULL PRESCRIBING INFORMATION WARNING: RISK OF SERIOUS CARDIOVASCULAR AND GASTROINTESTINAL EVENTS Cardiovascular Thrombotic Events • Nonsteroidal anti-inflammatory drugs (NSAIDs) cause an increased risk of serious cardiovascular thrombotic events, including myocardial infarction and stroke, which can be fatal. This risk may occur early in treatment and may increase with duration of use [see Warnings and Precautions (5.1)]. • INDOCIN is contraindicated in the setting of coronary artery bypass graft (CABG) surgery [see Contraindications (4) and Warnings and Precautions (5.1)]. Gastrointestinal Bleeding, Ulceration, and Perforation • NSAIDs cause an increased risk of serious gastrointestinal (GI) adverse events including bleeding, ulceration, and perforation of the stomach or intestines, which can be fatal. These events can occur at any time during use and without warning symptoms. Elderly patients and patients with a prior history of peptic ulcer disease and/or GI bleeding are at greater risk for serious GI events [see Warnings and Precautions (5.2)]. 1 INDICATIONS AND USAGE INDOCIN Suppository is indicated for:  Moderate to severe rheumatoid arthritis including acute flares of chronic disease  Moderate to severe ankylosing spondylitis  Moderate to severe osteoarthritis  Acute painful shoulder (bursitis and/or tendinitis)  Acute gouty arthritis 2 DOSAGE AND ADMINISTRATION 2.1 General Dosing Instructions Carefully consider the potential benefits and risks of INDOCIN and other treatment options before deciding to use INDOCIN. Use the lowest effective dosage for the shortest duration consistent with individual patient treatment goals [see Warnings and Precautions (5)]. After observing the response to initial therapy with indomethacin, the dose and frequency should be adjusted to suit an individual patient’s needs. Adverse reactions generally appear to correlate with the dose of indomethacin. Therefore, every effort should be made to determine the lowest effective dosage for the individual patient. SUPPOSITORIES: INDOCIN Suppositories are available as 50 mg suppositories for rectal use only. INDOCIN Suppositories are not for oral or intravaginal use. Reference ID: 3928090 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda 2.2 Suppository Dosing Instructions THIS SECTION PREDOMINANTLY MAKES REFERENCE TO INDOMETHACIN CAPSULE, USP ORAL DOSAGE FOR GUIDANCE IN USING SUPPOSITORIES. INDOCIN suppositories 50 mg can be substituted for indomethacin capsules, USP; however, there will be significant differences between the two dosage regimens in indomethacin blood levels [see Clinical Pharmacology (12.3)]. Oral dosage recommendations for active stages of the following: 2.3 Moderate to severe rheumatoid arthritis including acute flares of chronic disease; moderate to severe ankylosing spondylitis; and moderate to severe osteoarthritis Indomethacin capsules, USP 25 mg twice a day. or three times a day. If this is well tolerated, increase the daily dosage by 25 mg or by 50 mg, if required by continuing symptoms, at weekly intervals until a satisfactory response is obtained or until a total daily dose of 150 - 200 mg is reached. Doses above this amount generally do not increase the effectiveness of the drug. In patients who have persistent night pain and/or morning stiffness, the giving of a large portion, up to a maximum of 100 mg, of the total daily dose at bedtime, either orally or by rectal suppositories, may be helpful in affording relief. The total daily dose should not exceed 200 mg. In acute flares of chronic rheumatoid arthritis, it may be necessary to increase the dosage by 25 mg or, if required, by 50 mg daily. If minor adverse effects develop as the dosage is increased, reduce the dosage rapidly to a tolerated dose and observe the patient closely. If severe adverse reactions occur, stop the drug. After the acute phase of the disease is under control, an attempt to reduce the daily dose should be made repeatedly until the patient is receiving the smallest effective dose or the drug is discontinued. Careful instructions to, and observations of, the individual patient are essential to the prevention of serious, irreversible, including fatal, adverse reactions. As advancing years appear to increase the possibility of adverse reactions, INDOCIN should be used with greater care in the elderly. [see Use in Specific Populations (8.5)] 2.4 Acute painful shoulder (bursitis and/or tendinitis) Indomethacin capsules, USP 75-150 mg daily in 3 or 4 divided doses. The drug should be discontinued after the signs and symptoms of inflammation have been controlled for several days. The usual course of therapy is 7-14 days. 2.5 Acute Gouty Arthritis Indomethacin capsules, USP 50 mg three times a day. Until pain is tolerable. The dose should then be rapidly reduced to complete cessation of the drug. Definite relief of pain has been reported within 2 to 4 hours. Tenderness and heat usually subside in 24 to 36 hours, and swelling gradually disappears in 3 to 5 days. Reference ID: 3928090 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda 3 DOSAGE FORMS AND STRENGTHS INDOCIN Suppositories : 50 mg of indomethacin. White and opaque. 4 CONTRAINDICATIONS INDOCIN is contraindicated in the following patients:  Known hypersensitivity (e.g., anaphylactic reactions and serious skin reactions) to indomethacin or any components of the drug product [see Warnings and Precautions (5.7, 5.9)]  History of asthma, urticaria, or other allergic-type reactions after taking aspirin or other NSAIDs. Severe, sometimes fatal, anaphylactic reactions to NSAIDs have been reported in such patients [see Warnings and Precautions (5.7, 5.8)]  In the setting of coronary artery bypass graft (CABG) surgery [see Warnings and Precautions (5.1)]  In patients with a history of proctitis or recent rectal bleeding 5 WARNINGS AND PRECAUTIONS 5.1 Cardiovascular Thrombotic Events Clinical trials of several COX-2 selective and nonselective NSAIDs of up to three years duration have shown an increased risk of serious cardiovascular (CV) thrombotic events, including myocardial infarction (MI) and stroke, which can be fatal. Based on available data, it is unclear that the risk for CV thrombotic events is similar for all NSAIDs. The relative increase in serious CV thrombotic events over baseline conferred by NSAID use appears to be similar in those with and without known CV disease or risk factors for CV disease. However, patients with known CV disease or risk factors had a higher absolute incidence of excess serious CV thrombotic events, due to their increased baseline rate. Some observational studies found that this increased risk of serious CV thrombotic events began as early as the first weeks of treatment. The increase in CV thrombotic risk has been observed most consistently at higher doses. To minimize the potential risk for an adverse CV event in NSAID-treated patients, use the lowest effective dose for the shortest duration possible. Physicians and patients should remain alert for the development of such events, throughout the entire treatment course, even in the absence of previous CV symptoms. Patients should be informed about the symptoms of serious CV events and the steps to take if they occur. There is no consistent evidence that concurrent use of aspirin mitigates the increased risk of serious CV thrombotic events associated with NSAID use. The concurrent use of aspirin and an NSAID, such as indomethacin, increases the risk of serious gastrointestinal (GI) events [see Warnings and Precautions (5.2)]. Status Post Coronary Artery Bypass Graft (CABG) Surgery Two large, controlled clinical trials of a COX-2 selective NSAID for the treatment of pain in the first 10–14 days following CABG surgery found an increased incidence of myocardial infarction and stroke. NSAIDs are contraindicated in the setting of CABG [see Contraindications (4)]. Reference ID: 3928090 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda Post-MI Patients Observational studies conducted in the Danish National Registry have demonstrated that patients treated with NSAIDs in the post-MI period were at increased risk of reinfarction, CV-related death, and all-cause mortality beginning in the first week of treatment. In this same cohort, the incidence of death in the first year post-MI was 20 per 100 person years in NSAID-treated patients compared to 12 per 100 person years in non-NSAID exposed patients. Although the absolute rate of death declined somewhat after the first year post-MI, the increased relative risk of death in NSAID users persisted over at least the next four years of follow-up. Avoid the use of INDOCIN in patients with a recent MI unless the benefits are expected to outweigh the risk of recurrent CV thrombotic events. If INDOCIN is used in patients with a recent MI, monitor patients for signs of cardiac ischemia. 5.2 Gastrointestinal Bleeding, Ulceration, and Perforation NSAIDs, including indomethacin, cause serious gastrointestinal (GI) adverse events including inflammation, bleeding, ulceration, and perforation of the esophagus, stomach, small intestine, or large intestine, which can be fatal. These serious adverse events can occur at any time, with or without warning symptoms, in patients treated with NSAIDs. Only one in five patients who develop a serious upper GI adverse event on NSAID therapy is symptomatic. Upper GI ulcers, gross bleeding, or perforation caused by NSAIDs occurred in approximately 1% of patients treated for 3-6 months, and in about 2%-4% of patients treated for one year. However, even short-term NSAID therapy is not without risk. Risk Factors for GI Bleeding, Ulceration, and Perforation Patients with a prior history of peptic ulcer disease and/or GI bleeding who used NSAIDs had a greater than 10-fold increased risk for developing a GI bleed compared to patients without these risk factors. Other factors that increase the risk of GI bleeding in patients treated with NSAIDs include longer duration of NSAID therapy; concomitant use of oral corticosteroids, aspirin, anticoagulants, or selective serotonin reuptake inhibitors (SSRIs); smoking; use of alcohol; older age; and poor general health status. Most postmarketing reports of fatal GI events occurred in elderly or debilitated patients. Additionally, patients with advanced liver disease and/or coagulopathy are at increased risk for GI bleeding. Strategies to Minimize the GI Risks in NSAID-treated patients:  Use the lowest effective dosage for the shortest possible duration.  Avoid administration of more than one NSAID at a time.  Avoid use in patients at higher risk unless benefits are expected to outweigh the increased risk of bleeding. For such patients, as well as those with active GI bleeding, consider alternate therapies other than NSAIDs.  Remain alert for signs and symptoms of GI ulceration and bleeding during NSAID therapy.  If a serious GI adverse event is suspected, promptly initiate evaluation and treatment, and discontinue INDOCIN until a serious GI adverse event is ruled out.  In the setting of concomitant use of low-dose aspirin for cardiac prophylaxis, monitor patients more closely for evidence of GI bleeding [see Drug Interactions (7)]. Reference ID: 3928090 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda 5.3 Hepatotoxicity Elevations of ALT or AST (three or more times the upper limit of normal [ULN]) have been reported in approximately 1% of NSAID-treated patients in clinical trials. In addition, rare, sometimes fatal, cases of severe hepatic injury, including fulminant hepatitis, liver necrosis, and hepatic failure have been reported. Elevations of ALT or AST (less than three times ULN) may occur in up to 15% of patients treated with NSAIDs including indomethacin. Inform patients of the warning signs and symptoms of hepatotoxicity (e.g., nausea, fatigue, lethargy, diarrhea, pruritus, jaundice, right upper quadrant tenderness, and "flu-like" symptoms). If clinical signs and symptoms consistent with liver disease develop, or if systemic manifestations occur (e.g., eosinophilia, rash, etc.), discontinue INDOCIN immediately, and perform a clinical evaluation of the patient. 5.4 Hypertension NSAIDs, including INDOCIN, can lead to new onset of hypertension or worsening of preexisting hypertension, either of which may contribute to the increased incidence of CV events. Patients taking angiotensin converting enzyme (ACE) inhibitors, thiazide diuretics, or loop diuretics may have impaired response to these therapies when taking NSAIDs [see Drug Interactions (7)]. Monitor blood pressure (BP) during the initiation of NSAID treatment and throughout the course of therapy. 5.5 Heart Failure and Edema The Coxib and traditional NSAID Trialists’ Collaboration meta-analysis of randomized controlled trials demonstrated an approximately two-fold increase in hospitalizations for heart failure in COX-2 selective-treated patients and nonselective NSAID-treated patients compared to placebo-treated patients. In a Danish National Registry study of patients with heart failure, NSAID use increased the risk of MI, hospitalization for heart failure, and death. Additionally, fluid retention and edema have been observed in some patients treated with NSAIDs. Use of indomethacin may blunt the CV effects of several therapeutic agents used to treat these medical conditions (e.g., diuretics, ACE inhibitors, or angiotensin receptor blockers [ARBs]) [see Drug Interactions (7)]. Avoid the use of INDOCIN in patients with severe heart failure unless the benefits are expected to outweigh the risk of worsening heart failure. If INDOCIN is used in patients with severe heart failure, monitor patients for signs of worsening heart failure. 5.6 Renal Toxicity and Hyperkalemia Renal Toxicity Long-term administration of NSAIDs has resulted in renal papillary necrosis and other renal injury. Renal toxicity has also been seen in patients in whom renal prostaglandins have a compensatory role in the maintenance of renal perfusion. In these patients, administration of Reference ID: 3928090 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda an NSAID may cause a dose-dependent reduction in prostaglandin formation and, secondarily, in renal blood flow, which may precipitate overt renal decompensation. Patients at greatest risk of this reaction are those with impaired renal function, dehydration, hypovolemia, heart failure, liver dysfunction, those taking diuretics and ACE inhibitors or ARBs, and the elderly. Discontinuation of NSAID therapy is usually followed by recovery to the pretreatment state. No information is available from controlled clinical studies regarding the use of INDOCIN in patients with advanced renal disease. The renal effects of INDOCIN may hasten the progression of renal dysfunction in patients with preexisting renal disease. Correct volume status in dehydrated or hypovolemic patients prior to initiating INDOCIN. Monitor renal function in patients with renal or hepatic impairment, heart failure, dehydration, or hypovolemia during use of INDOCIN [see Drug Interactions (7)]. Avoid the use of INDOCIN in patients with advanced renal disease unless the benefits are expected to outweigh the risk of worsening renal function. If INDOCIN is used in patients with advanced renal disease, monitor patients for signs of worsening renal function. It has been reported that the addition of the potassium-sparing diuretic, triamterene, to a maintenance schedule of indomethacin resulted in reversible acute renal failure in two of four healthy volunteers. Indomethacin and triamterene should not be administered together. Hyperkalemia Increases in serum potassium concentration, including hyperkalemia, have been reported with use of NSAIDs, even in some patients without renal impairment. In patients with normal renal function, these effects have been attributed to a hyporeninemic-hypoaldosteronism state. Both indomethacin and potassium-sparing diuretics may be associated with increased serum potassium levels. The potential effects of indomethacin and potassium-sparing diuretics on potassium levels and renal function should be considered when these agents are administered concurrently. 5.7 Anaphylactic Reactions Indomethacin has been associated with anaphylactic reactions in patients with and without known hypersensitivity to indomethacin and in patients with aspirin-sensitive asthma [see Contraindications (4) and Warnings and Precautions (5.8)]. Seek emergency help if an anaphylactic reaction occurs. 5.8 Exacerbation of Asthma Related to Aspirin Sensitivity A subpopulation of patients with asthma may have aspirin-sensitive asthma which may include chronic rhinosinusitis complicated by nasal polyps; severe, potentially fatal bronchospasm; and/or intolerance to aspirin and other NSAIDs. Because cross-reactivity between aspirin and other NSAIDs has been reported in such aspirin-sensitive patients, INDOCIN is contraindicated in patients with this form of aspirin sensitivity [see Contraindications (4)]. When INDOCIN is used in patients with preexisting asthma (without known aspirin sensitivity), monitor patients for changes in the signs and symptoms of asthma. Reference ID: 3928090 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda 5.9 Serious Skin Reactions NSAIDs, including indomethacin, can cause serious skin adverse reactions such as exfoliative dermatitis, Stevens-Johnson Syndrome (SJS), and toxic epidermal necrolysis (TEN), which can be fatal. These serious events may occur without warning. Inform patients about the signs and symptoms of serious skin reactions, and to discontinue the use of INDOCIN at the first appearance of skin rash or any other sign of hypersensitivity. INDOCIN is contraindicated in patients with previous serious skin reactions to NSAIDs [see Contraindications (4)]. 5.10 Premature Closure of Fetal Ductus Arteriosus Indomethacin may cause premature closure of the fetal ductus arteriosus. Avoid use of NSAIDs, including INDOCIN, in pregnant women starting at 30 weeks of gestation (third trimester) [see Use in Specific Populations (8.1)]. 5.11 Hematologic Toxicity Anemia has occurred in NSAID-treated patients. This may be due to occult or gross blood loss, fluid retention, or an incompletely described effect on erythropoiesis. If a patient treated with INDOCIN has any signs or symptoms of anemia, monitor hemoglobin or hematocrit. NSAIDs, including INDOCIN, may increase the risk of bleeding events. Co-morbid conditions, such as coagulation disorders, or concomitant use of warfarin, other anticoagulants, antiplatelet agents (e.g., aspirin), serotonin reuptake inhibitors (SSRIs) and serotonin norepinephrine reuptake inhibitors (SNRIs) may increase this risk. Monitor these patients for signs of bleeding [see Drug Interactions (7)]. 5.12 Masking of Inflammation and Fever The pharmacological activity of INDOCIN in reducing inflammation, and possibly fever, may diminish the utility of diagnostic signs in detecting infections. 5.13 Laboratory Monitoring Because serious GI bleeding, hepatotoxicity, and renal injury can occur without warning symptoms or signs, consider monitoring patients on long-term NSAID treatment with a CBC and a chemistry profile periodically [see Warnings and Precautions (5.2, 5.3, 5.6)]. 5.14 Central Nervous System Effects INDOCIN may aggravate depression or other psychiatric disturbances, epilepsy, and parkinsonism, and should be used with considerable caution in patients with these conditions. Discontinue INDOCIN if severe CNS adverse reactions develop. INDOCIN may cause drowsiness; therefore, caution patients about engaging in activities requiring mental alertness and motor coordination, such as driving a car. Indomethacin may also cause headache. Headache which persists despite dosage reduction requires cessation of therapy with INDOCIN. 5.15 Ocular Effects Corneal deposits and retinal disturbances, including those of the macula, have been observed in some patients who had received prolonged therapy with INDOCIN. Be alert to the Reference ID: 3928090 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda possible association between the changes noted and INDOCIN. It is advisable to discontinue therapy if such changes are observed. Blurred vision may be a significant symptom and warrants a thorough ophthalmological examination. Since these changes may be asymptomatic, ophthalmologic examination at periodic intervals is desirable in patients receiving prolonged therapy. INDOCIN is not indicated for long-term treatment. 6 ADVERSE REACTIONS The following adverse reactions are discussed in greater detail in other sections of the labeling:  Cardiovascular Thrombotic Events [see Warnings and Precautions (5.1)]  GI Bleeding, Ulceration and Perforation [see Warnings and Precautions (5.2)]  Hepatotoxicity [see Warnings and Precautions (5.3)]  Hypertension [see Warnings and Precautions (5.4)]  Heart Failure and Edema [see Warnings and Precautions (5.5)]  Renal Toxicity and Hyperkalemia [see Warnings and Precautions (5.6)]  Anaphylactic Reactions [see Warnings and Precautions (5.7)]  Serious Skin Reactions [see Warnings and Precautions (5.9)]  Hematologic Toxicity [see Warnings and Precautions (5.11)] 6.1 Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in clinical practice. In a gastroscopic study in 45 healthy subjects, the number of gastric mucosal abnormalities was significantly higher in the group receiving INDOCIN Capsules than in the group taking INDOCIN Suppositories or placebo. In a double-blind comparative clinical study involving 175 patients with rheumatoid arthritis, however, the incidence of upper gastrointestinal adverse effects with INDOCIN Suppositories or Capsules was comparable. The incidence of lower gastrointestinal adverse effects was greater in the suppository group. The adverse reactions for INDOCIN Capsules listed in the following table have been arranged into two groups: (1) incidence greater than 1%; and (2) incidence less than 1%. The incidence for group (1) was obtained from 33 double-blind controlled clinical trials reported in the literature (1,092 patients). The incidence for group (2) was based on reports in clinical trials, in the literature, and on voluntary reports since marketing. The probability of a causal relationship exists between INDOCIN and these adverse reactions, some of which have been reported only rarely. The adverse reactions reported with INDOCIN Capsules may occur with use of the suppositories. In addition, rectal irritation and tenesmus have been reported in patients who have received the suppositories.

(Those reactions occurring in less than 3% of the patients are unmarked.) Causal relationship unknown: Other reactions have been reported but occurred under circumstances where a causal relationship could not be established. However, in these rarely reported events, the possibility cannot be excluded. Therefore, these observations are being listed to serve as alerting information to physicians: Cardiovascular: Thrombophlebitis Hematologic: Although there have been several reports of leukemia, the supporting information is weak Genitourinary: Urinary frequency A rare occurrence of fulminant necrotizing fasciitis, particularly in association with Group Aβ hemolytic streptococcus, has been described in persons treated with nonsteroidal anti-inflammatory agents, including indomethacin, sometimes with fatal outcome 7 DRUG INTERACTIONS See Table 2 for clinically significant drug interactions with indomethacin. Table 2 Clinically Significant Drug Interactions with Indomethacin Drugs That Interfere with Hemostasis Clinical Impact:  Indomethacin and anticoagulants such as warfarin have a synergistic effect on bleeding. The concomitant use of indomethacin and anticoagulants have an increased risk of serious bleeding compared to the use of either drug alone.  Serotonin release by platelets plays an important role in hemostasis. Case-control and Reference ID: 3928090 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda cohort epidemiological studies showed that concomitant use of drugs that interfere with serotonin reuptake and an NSAID may potentiate the risk of bleeding more than an NSAID alone. Intervention: Monitor patients with concomitant use of INDOCIN with anticoagulants (e.g., warfarin), antiplatelet agents (e.g., aspirin), selective serotonin reuptake inhibitors (SSRIs), and serotonin norepinephrine reuptake inhibitors (SNRIs) for signs of bleeding [see Warnings and Precautions (5.11)]. Aspirin Clinical Impact: Controlled clinical studies showed that the concomitant use of NSAIDs and analgesic doses of aspirin does not produce any greater therapeutic effect than the use of NSAIDs alone. In a clinical study, the concomitant use of an NSAID and aspirin was associated with a significantly increased incidence of GI adverse reactions as compared to use of the NSAID alone [see Warnings and Precautions (5.2)]. Intervention: Concomitant use of INDOCIN and analgesic doses of aspirin is not generally recommended because of the increased risk of bleeding [see Warnings and Precautions (5.11)]. INDOCIN is not a substitute for low dose aspirin for cardiovascular protection. ACE Inhibitors, Angiotensin Receptor Blockers, and Beta-Blockers Clinical Impact:  NSAIDs may diminish the antihypertensive effect of angiotensin converting enzyme (ACE) inhibitors, angiotensin receptor blockers (ARBs), or beta-blockers (including propranolol).  In patients who are elderly, volume-depleted (including those on diuretic therapy), or have renal impairment, co-administration of an NSAID with ACE inhibitors or ARBs may result in deterioration of renal function, including possible acute renal failure. These effects are usually reversible. Intervention:  During concomitant use of INDOCIN and ACE-inhibitors, ARBs, or beta-blockers, monitor blood pressure to ensure that the desired blood pressure is obtained.  During concomitant use of INDOCIN and ACE-inhibitors or ARBs in patients who are elderly, volume-depleted, or have impaired renal function, monitor for signs of worsening renal function [see Warnings and Precautions (5.6)].  When these drugs are administered concomitantly, patients should be adequately hydrated. Assess renal function at the beginning of the concomitant treatment and periodically thereafter. Diuretics Clinical Impact: Clinical studies, as well as post-marketing observations, showed that NSAIDs reduced the natriuretic effect of loop diuretics (e.g., furosemide) and thiazide diuretics in some patients. This effect has been attributed to the NSAID inhibition of renal prostaglandin synthesis. It has been reported that the addition of triamterene to a maintenance schedule of INDOCIN resulted in reversible acute renal failure in two of four healthy volunteers. INDOCIN and triamterene should not be administered together. Both INDOCIN and potassium-sparing diuretics may be associated with increased serum potassium levels. The potential effects of INDOCIN and potassium-sparing diuretics on potassium levels and renal function should be considered when these agents are administered concurrently. Intervention: Indomethacin and triamterene should not be administered together. During concomitant use of INDOCIN with diuretics, observe patients for signs of worsening renal function, in addition to assuring diuretic efficacy including antihypertensive effects. Be aware that indomethacin and potassium-sparing diuretics may both be associated with increased serum potassium levels [see Warnings and Precautions (5.6)]. Digoxin Reference ID: 3928090 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda Clinical Impact: The concomitant use of indomethacin with digoxin has been reported to increase the serum concentration and prolong the half-life of digoxin. Intervention: During concomitant use of INDOCIN and digoxin, monitor serum digoxin levels. Lithium Clinical Impact: NSAIDs have produced elevations in plasma lithium levels and reductions in renal lithium clearance. The mean minimum lithium concentration increased 15%, and the renal clearance decreased by approximately 20%. This effect has been attributed to NSAID inhibition of renal prostaglandin synthesis. Intervention: During concomitant use of INDOCIN and lithium, monitor patients for signs of lithium toxicity. Methotrexate Clinical Impact: Concomitant use of NSAIDs and methotrexate may increase the risk for methotrexate toxicity (e.g., neutropenia, thrombocytopenia, renal dysfunction). Intervention: During concomitant use of INDOCIN and methotrexate, monitor patients for methotrexate toxicity. Cyclosporine Clinical Impact: Concomitant use of INDOCIN and cyclosporine may increase cyclosporine’s nephrotoxicity. Intervention: During concomitant use of INDOCIN and cyclosporine, monitor patients for signs of worsening renal function. NSAIDs and Salicylates Clinical Impact: Concomitant use of indomethacin with other NSAIDs or salicylates (e.g., diflunisal, salsalate) increases the risk of GI toxicity, with little or no increase in efficacy [see Warnings and Precautions (5.2)]. Combined use with diflunisal may be particularly hazardous because diflunisal causes significantly higher plasma levels of indomethacin [see Clinical Pharmacology (12.3)]. In some patients, combined use of indomethacin and diflunisal has been associated with fatal gastrointestinal hemorrhage. Intervention: The concomitant use of indomethacin with other NSAIDs or salicylates, especially diflunisal, is not recommended. Pemetrexed Clinical Impact: Concomitant use of INDOCIN and pemetrexed may increase the risk of pemetrexed­ associated myelosuppression, renal, and GI toxicity (see the pemetrexed prescribing information). Intervention: During concomitant use of INDOCIN and pemetrexed, in patients with renal impairment whose creatinine clearance ranges from 45 to 79 mL/min, monitor for myelosuppression, renal and GI toxicity. NSAIDs with short elimination half-lives (e.g., diclofenac, indomethacin) should be avoided for a period of two days before, the day of, and two days following administration of pemetrexed. In the absence of data regarding potential interaction between pemetrexed and NSAIDs with longer half-lives (e.g., meloxicam, nabumetone), patients taking these NSAIDs should interrupt dosing for at least five days before, the day of, and two days following pemetrexed administration. Probenecid Clinical Impact: When indomethacin is given to patients receiving probenecid, the plasma levels of indomethacin are likely to be increased.

For current labeling information, please visit https://www.fda.gov/drugsatfda During the concomitant use of INDOCIN and probenecid, a lower total daily dosage of Intervention: indomethacin may produce a satisfactory therapeutic effect. When increases in the dose of indomethacin are made, they should be made carefully and in small increments. Effects on Laboratory Tests INDOCIN reduces basal plasma renin activity (PRA), as well as those elevations of PRA induced by furosemide administration, or salt or volume depletion. These facts should be considered when evaluating plasma renin activity in hypertensive patients. False-negative results in the dexamethasone suppression test (DST) in patients being treated with indomethacin have been reported. Thus, results of the DST should be interpreted with caution in these patients. 8 USE IN SPECIFIC POPULATIONS 8.1 Pregnancy Risk Summary Use of NSAIDs, including INDOCIN, during the third trimester of pregnancy increases the risk of premature closure of the fetal ductus arteriosus. Avoid use of NSAIDs, including INDOCIN, in pregnant women starting at 30 weeks of gestation (third trimester). There are no adequate and well-controlled studies of INDOCIN in pregnant women. Data from observational studies regarding potential embryofetal risks of NSAID use in women in the first or second trimesters of pregnancy are inconclusive. In the general U.S. population, all clinically recognized pregnancies, regardless of drug exposure, have a background rate of 2-4% for major malformations, and 15-20% for pregnancy loss. In animal reproduction studies retarded fetal ossification was observed with administration of indomethacin to mice and rats during organogenesis at doses 0.1 and 0.2 times, respectively, the maximum recommended human dose (MRHD, 200 mg). In published studies in pregnant mice, indomethacin produced maternal toxicity and death, increased fetal resorptions, and fetal malformations at 0.1 times the MRHD. When rat and mice dams were dosed during the last three days of gestation, indomethacin produced neuronal necrosis in the offspring at 0.1 and 0.05 times the MRHD, respectively [see Data]. Based on animal data, prostaglandins have been shown to have an important role in endometrial vascular permeability, blastocyst implantation, and decidualization. In animal studies, administration of prostaglandin synthesis inhibitors such as indomethacin, resulted in increased pre- and post-implantation loss. Clinical Considerations Labor or Delivery There are no studies on the effects of INDOCIN during labor or delivery. In animal studies, NSAIDs, including indomethacin, inhibit prostaglandin synthesis, cause delayed parturition, and increase the incidence of stillbirth. Reference ID: 3928090 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda Data Animal data Reproductive studies were conducted in mice and rats at dosages of 0.5, 1.0, 2.0, and 4.0 mg/kg/day. Except for retarded fetal ossification at 4 mg/kg/day (0.1 times [mice] and 0.2 times [rats] the MRHD on a mg/m2 basis, respectively) considered secondary to the decreased average fetal weights, no increase in fetal malformations was observed as compared with control groups. Other studies in mice reported in the literature using higher doses (5 to 15 mg/kg/day, 0.1 to 0.4 times MRHD on a mg/m2 basis) have described maternal toxicity and death, increased fetal resorptions, and fetal malformations. Comparable studies in rodents using high doses of aspirin have shown similar maternal and fetal effects. In rats and mice, maternal indomethacin administration of 4.0 mg/kg/day (0.2 times and 0.1 times the MRHD on a mg/m2 basis) during the last 3 days of gestation was associated with an increased incidence of neuronal necrosis in the diencephalon in the live-born fetuses however no increase in neuronal necrosis was observed at 2.0 mg/kg/day as compared to the control groups (0.1 times and 0.05 times the MRHD on a mg/m2 basis). Administration of 0.5 or 4.0 mg/kg/day to offspring during the first 3 days of life did not cause an increase in neuronal necrosis at either dose level. 8.2 Lactation Risk Summary Based on available published clinical data, indomethacin may be present in human milk. The developmental and health benefits of breastfeeding should be considered along with the mother’s clinical need for INDOCIN and any potential adverse effects on the breastfed infant from the INDOCIN or from the underlying maternal condition. Data In one study, levels of indomethacin in breast milk were below the sensitivity of the assay (<20 mcg/L) in 11 of 15 women using doses ranging from 75 mg orally to 300 mg rectally daily (0.94 to 4.29 mg/kg daily) in the postpartum period. Based on these levels, the average concentration present in breast milk was estimated to be 0.27% of the maternal weight- adjusted dose. In another study indomethacin levels were measured in breast milk of eight postpartum women using doses of 75 mg daily and the results were used to calculate an estimated infant daily dose. The estimated infant dose of indomethacin from breast milk was less than 30 mcg/day or 4.5 mcg/kg/day assuming breast milk intake of 150 mL/kg/day. This is 0.5% of the maternal weight-adjusted dosage or about 3% of the neonatal dose for treatment of patent ductus arteriosus. 8.3 Females and Males of Reproductive Potential Infertility Females Based on the mechanism of action, the use of prostaglandin-mediated NSAIDs, including INDOCIN, may delay or prevent rupture of ovarian follicles, which has been associated with reversible infertility in some women. Published animal studies have shown that administration of prostaglandin synthesis inhibitors has the potential to disrupt prostaglandin- mediated follicular rupture required for ovulation. Small studies in women treated with NSAIDs have also shown a reversible delay in ovulation. Consider withdrawal of NSAIDs, including INDOCIN, in women who have difficulties conceiving or who are undergoing investigation of infertility. Reference ID: 3928090 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda 8.4 Pediatric Use Safety and effectiveness in pediatric patients 14 years of age and younger has not been established. INDOCIN should not be prescribed for pediatric patients 14 years of age and younger unless toxicity or lack of efficacy associated with other drugs warrants the risk. In experience with more than 900 pediatric patients reported in the literature or to the manufacturer who were treated with INDOCIN Capsules, side effects in pediatric patients were comparable to those reported in adults. Experience in pediatric patients has been confined to the use of INDOCIN Capsules. If a decision is made to use indomethacin for pediatric patients two years of age or older, such patients should be monitored closely and periodic assessment of liver function is recommended. There have been cases of hepatotoxicity reported in pediatric patients with juvenile rheumatoid arthritis, including fatalities. If indomethacin treatment is instituted, a suggested starting dose is 1-2 mg/kg/day given in divided doses. Maximum daily dosage should not exceed 3 mg/kg/day or 150-200 mg/day, whichever is less. Limited data are available to support the use of a maximum daily dosage of 4 mg/kg/day or 150-200 mg/day, whichever is less. As symptoms subside, the total daily dosage should be reduced to the lowest level required to control symptoms, or the drug should be discontinued. 8.5 Geriatric Use Elderly patients, compared to younger patients, are at greater risk for NSAID-associated serious cardiovascular, gastrointestinal, and/or renal adverse reactions. If the anticipated benefit for the elderly patient outweighs these potential risks, start dosing at the low end of the dosing range, and monitor patients for adverse effects [see Warnings and Precautions (5.1, 5.2, 5.3, 5.6, 5.13)]. Indomethacin may cause confusion or rarely, psychosis [see Adverse Reactions (6.1)]; physicians should remain alert to the possibility of such adverse effects in the elderly. Indomethacin and its metabolites are known to be substantially excreted by the kidneys, and the risk of adverse reactions to this drug may be greater in patients with impaired renal function. Because elderly patients are more likely to have decreased renal function, use caution in this patient population, and it may be useful to monitor renal function [see Clinical Pharmacology (12.3)]. 10 OVERDOSAGE Symptoms following acute NSAID overdosages have been typically limited to lethargy, drowsiness, nausea, vomiting, and epigastric pain, which have been generally reversible with supportive care. Gastrointestinal bleeding has occurred. Hypertension, acute renal failure, respiratory depression, and coma have occurred, but were rare [see Warnings and Precautions (5.1, 5.2, 5.4, 5.6)]. Manage patients with symptomatic and supportive care following an NSAID overdosage. There are no specific antidotes. Consider emesis and/or activated charcoal (60 to 100 grams in adults, 1 to 2 grams per kg of body weight in pediatric patients) and/or osmotic cathartic in symptomatic patients seen within four hours of ingestion or in patients with a large Reference ID: 3928090 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda overdosage (5 to 10 times the recommended dosage). Forced diuresis, alkalinization of urine, hemodialysis, or hemoperfusion may not be useful due to high protein binding. For additional information about overdosage treatment contact a poison control center (1­ 800-222-1222). 11 DESCRIPTION INDOCIN (indomethacin) Suppositories is a nonsteroidal anti-inflammatory drug, available as a suppository containing 50 mg of indomethacin administered for rectal use. The chemical name is 1-(4-chlorobenzoyl)-5-methoxy-2-methyl-1H-indole-3-acetic acid. The molecular weight is 357.8. Its molecular formula is C19H16ClNO4 , and it has the following chemical structure. structural formula Indomethacin is a white to yellow crystalline powder. It is practically insoluble in water and sparingly soluble in alcohol. It has a pKa of 4.5 and is stable in neutral or slightly acidic media and decomposes in strong alkali. The inactive ingredients in INDOCIN Suppositories include: butylated hydroxyanisole, butylated hydroxytoluene, edetic acid, glycerin, polyethylene glycol 3350, polyethylene glycol 8000 and sodium chloride. INDOCIN Suppositories, 50 mg each, are white, opaque, rectal suppositories. 12 CLINICAL PHARMACOLOGY 12.1 Mechanism of Action Indomethacin has analgesic, anti-inflammatory, and antipyretic properties. The mechanism of action of INDOCIN, like that of other NSAIDs, is not completely understood but involves inhibition of cyclooxygenase (COX-1 and COX-2). Indomethacin is a potent inhibitor of prostaglandin synthesis in vitro. Indomethacin concentrations reached during therapy have produced in vivo effects. Prostaglandins sensitize afferent nerves and potentiate the action of bradykinin in inducing pain in animal models. Prostaglandins are mediators of inflammation. Because indomethacin is an inhibitor of prostaglandin synthesis, its mode of action may be due to a decrease of prostaglandins in peripheral tissues. Reference ID: 3928090 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda 12.3 Pharmacokinetics Absorption Following single oral doses of INDOCIN Capsules 25 mg or 50 mg, indomethacin is readily absorbed, attaining peak plasma concentrations of about 1 and 2 mcg/mL, respectively, at about 2 hours. Orally administered INDOCIN Capsules are virtually 100% bioavailable, with 90% of the dose absorbed within 4 hours. With a typical therapeutic regimen of 25 or 50 mg three times a day, the steady-state plasma concentrations of indomethacin are an average 1.4 times those following the first dose. The rate of absorption is more rapid from the rectal suppository than from INDOCIN Capsules. Ordinarily, therefore, the total amount absorbed from the suppository would be expected to be at least equivalent to the capsule. In controlled clinical trials, however, the amount of indomethacin absorbed was found to be somewhat less (80-90%) than that absorbed from INDOCIN Capsules. This is probably because some subjects did not retain the material from the suppository for the one hour necessary to assure complete absorption. Since the suppository dissolves rather quickly rather than melting slowly, it is seldom recovered in recognizable form if the patient retains the suppository for more than a few minutes. Distribution Indomethacin is highly bound to protein in plasma (about 99%) over the expected range of therapeutic plasma concentrations. Indomethacin has been found to cross the blood-brain barrier and the placenta, and appears in breast milk. Elimination Metabolism Indomethacin exists in the plasma as the parent drug and its desmethyl, desbenzoyl, and desmethyldesbenzoyl metabolites, all in the unconjugated form. Appreciable formation of glucuronide conjugates of each metabolite and of indomethacin are formed. Excretion Indomethacin is eliminated via renal excretion, metabolism, and biliary excretion. Indomethacin undergoes appreciable enterohepatic circulation. About 60% of an oral dose is recovered in urine as drug and metabolites (26% as indomethacin and its glucuronide), and 33% is recovered in feces (1.5% as indomethacin). The mean half-life of indomethacin is estimated to be about 4.5 hours. Specific Populations Pediatric: The pharmacokinetics of INDOCIN has not been investigated in pediatric patients. Race: Pharmacokinetic differences due to race have not been identified. Hepatic Impairment: The pharmacokinetics of INDOCIN has not been investigated in patients with hepatic impairment. Renal Impairment: The pharmacokinetics of INDOCIN has not been investigated in patients with renal impairment [see Warnings and Precautions (5.6)]. Reference ID: 3928090 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda Drug Interaction Studies Aspirin: In a study in normal volunteers, it was found that chronic concurrent administration of 3.6 g of aspirin per day decreases indomethacin blood levels approximately 20% [see Drug Interactions (7)]. When NSAIDs were administered with aspirin, the protein binding of NSAIDs were reduced, although the clearance of free NSAID was not altered. The clinical significance of this interaction is not known. See Table 2 for clinically significant drug interactions of NSAIDs with aspirin [see Drug Interactions (7)]. Diflunisal: In normal volunteers receiving indomethacin, the administration of diflunisal decreased the renal clearance and significantly increased the plasma levels of indomethacin [see Drug Interactions (7)]. 13 NONCLINICAL TOXICOLOGY 13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility Carcinogenesis In an 81-week chronic oral toxicity study in the rat at doses up to 1 mg/kg/day (0.05 times the MRHD on a mg/m2 basis), indomethacin had no tumorigenic effect. Indomethacin produced no neoplastic or hyperplastic changes related to treatment in carcinogenic studies in the rat (dosing period 73 to 110 weeks) and the mouse (dosing period 62 to 88 weeks) at doses up to 1.5 mg/kg/day (0.04 times [mice] and 0.07 times [rats] the MRHD on a mg/m2 basis, respectively). Mutagenesis Indomethacin did not have any mutagenic effect in in vitro bacterial tests and a series of in vivo tests including the host-mediated assay, sex-linked recessive lethals in Drosophila, and the micronucleus test in mice. Impairment of Fertility Indomethacin at dosage levels up to 0.5 mg/kg/day had no effect on fertility in mice in a two generation reproduction study (0.01 times the MRHD on a mg/m2 basis) or a two litter reproduction study in rats (0.02 times the MRHD on a mg/m2 basis). 14 CLINICAL STUDIES INDOCIN has been shown to be an effective anti-inflammatory agent, appropriate for long- term use in rheumatoid arthritis, ankylosing spondylitis, and osteoarthritis. INDOCIN affords relief of symptoms; it does not alter the progressive course of the underlying disease. INDOCIN suppresses inflammation in rheumatoid arthritis as demonstrated by relief of pain, and reduction of fever, swelling and tenderness. Improvement in patients treated with INDOCIN for rheumatoid arthritis has been demonstrated by a reduction in joint swelling, average number of joints involved, and morning stiffness; by increased mobility as demonstrated by a decrease in walking time; and by improved functional capability as demonstrated by an increase in grip strength. INDOCIN may enable the reduction of steroid Reference ID: 3928090 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda dosage in patients receiving steroids for the more severe forms of rheumatoid arthritis. In such instances the steroid dosage should be reduced slowly and the patients followed very closely for any possible adverse effects. 16 HOW SUPPLIED/STORAGE AND HANDLING INDOCIN (indomethacin) Suppositories, 50 mg each, are white, opaque, rectal suppositories.

For current labeling information, please visit https://www.fda.gov/drugsatfda Medication Guide for Nonsteroidal Anti-inflammatory Drugs (NSAIDs) What is the most important information I should know about medicines called Nonsteroidal Anti- inflammatory Drugs (NSAIDs)? NSAIDs can cause serious side effects, including:  Increased risk of a heart attack or stroke that can lead to death. This risk may happen early in treatment and may increase: o with increasing doses of NSAIDs o with longer use of NSAIDs Do not take NSAIDs right before or after a heart surgery called a “coronary artery bypass graft (CABG)." Avoid taking NSAIDs after a recent heart attack, unless your healthcare provider tells you to. You may have an increased risk of another heart attack if you take NSAIDs after a recent heart attack.  Increased risk of bleeding, ulcers, and tears (perforation) of the esophagus (tube leading from the mouth to the stomach), stomach and intestines: o anytime during use o without warning symptoms o that may cause death The risk of getting an ulcer or bleeding increases with: o past history of stomach ulcers, or stomach or intestinal bleeding with use of NSAIDs o taking medicines called “corticosteroids”, “anticoagulants”, “SSRIs”, or “SNRIs” o increasing doses of NSAIDs o longer use of NSAIDs o smoking o drinking alcohol o older age o poor health o advanced liver disease o bleeding problems NSAIDs should only be used: o exactly as prescribed o at the lowest dose possible for your treatment o for the shortest time needed What are NSAIDs? NSAIDs are used to treat pain and redness, swelling, and heat (inflammation) from medical conditions such as different types of arthritis, menstrual cramps, and other types of short-term pain. Who should not take NSAIDs? Do not take NSAIDs:  if you have had an asthma attack, hives, or other allergic reaction with aspirin or any other NSAIDs.  right before or after heart bypass surgery. Before taking NSAIDs, tell your healthcare provider about all of your medical conditions, including if you:  have liver or kidney problems  have high blood pressure  have asthma  are pregnant or plan to become pregnant. Talk to your healthcare provider if you are considering taking NSAIDs during pregnancy. You should not take NSAIDs after 29 weeks of pregnancy.  are breastfeeding or plan to breast feed. Tell your healthcare provider about all of the medicines you take, including prescription or over-the­ counter medicines, vitamins or herbal supplements. NSAIDs and some other medicines can interact with each other and cause serious side effects. Do not start taking any new medicine without talking to your healthcare provider first. What are the possible side effects of NSAIDs? NSAIDs can cause serious side effects, including: See “What is the most important information I should know about medicines called Nonsteroidal Anti- inflammatory Drugs (NSAIDs)?”  new or worse high blood pressure  heart failure  liver problems including liver failure  kidney problems including kidney failure  low red blood cells (anemia) Reference ID: 3928090 This label may not be the latest approved by FDA.

1 HALOG OINTMENT (Halcinonide Ointment, USP) 0.1% For Topical Use Only. Not For Ophthalmic Use. DESCRIPTION The topical corticosteroids constitute a class of primarily synthetic steroids used as anti- inflammatory and antipruritic agents. The steroids in this class include halcinonide. Halcinonide is designated chemically as 21-Chloro-9-fluoro-11β,16α, 17-trihydroxy- pregn-4-ene-3,20-dione cyclic 16,17-acetal with acetone. Graphic formula: C24H32ClFO5, MW 454.96, CAS-3093-35-4 Each gram of 0.1% HALOG OINTMENT (Halcinonide Ointment, USP) contains 1 mg halcinonide in Plastibase (Plasticized Hydrocarbon Gel), a mineral oil and polyethylene gel base, polyethylene glycol 300, polyethylene glycol 400, polyethylene glycol 1450, and polyethylene glycol 6000 distearate with butylated hydroxytoluene as an antioxidant. CLINICAL PHARMACOLOGY Topical corticosteroids share anti-inflammatory, antipruritic and vasoconstrictive actions. The mechanism of anti-inflammatory activity of the topical corticosteroids is unclear. Various laboratory methods, including vasoconstrictor assays, are used to compare and predict potencies and/or clinical efficacies of the topical corticosteroids. There is some Rx only This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda 2 evidence to suggest that a recognizable correlation exists between vasoconstrictor potency and therapeutic efficacy in man. Pharmacokinetics The extent of percutaneous absorption of topical corticosteroids is determined by many factors including the vehicle, the integrity of the epidermal barrier, and the use of occlusive dressings. Topical corticosteroids can be absorbed from normal intact skin. Inflammation and/or other disease processes in the skin increase percutaneous absorption. Occlusive dressings substantially increase the percutaneous absorption of topical corticosteroids. Thus, occlusive dressings may be a valuable therapeutic adjunct for treatment of resistant dermatoses (see DOSAGE AND ADMINISTRATION). Once absorbed through the skin, topical corticosteroids are handled through pharmacokinetic pathways similar to systemically administered corticosteroids. Corticosteroids are bound to plasma proteins in varying degrees. Corticosteroids are metabolized primarily in the liver and are then excreted by the kidneys. Some of the topical corticosteroids and their metabolites are also excreted into the bile. INDICATIONS AND USAGE HALOG OINTMENT (Halcinonide Ointment, USP) 0.1% is indicated for the relief of the inflammatory and pruritic manifestations of corticosteroid-responsive dermatoses. CONTRAINDICATIONS Topical corticosteroids are contraindicated in those patients with a history of hypersensitivity to any of the components of the preparations. PRECAUTIONS General Systemic absorption of topical corticosteroids has produced reversible hypothalamic- pituitary-adrenal (HPA) axis suppression, manifestations of Cushing’s syndrome, hyperglycemia, and glucosuria in some patients. This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda 3 Conditions which augment systemic absorption include the application of the more potent steroids, use over large surface areas, prolonged use, and the addition of occlusive dressings. Therefore, patients receiving a large dose of any potent topical steroid applied to a large surface area or under an occlusive dressing should be evaluated periodically for evidence of HPA axis suppression by using the urinary free cortisol and ACTH stimulation tests, and for impairment of thermal homeostasis. If HPA axis suppression or elevation of the body temperature occurs, an attempt should be made to withdraw the drug, to reduce the frequency of application, substitute a less potent steroid, or use a sequential approach when utilizing the occlusive technique. Recovery of HPA axis function and thermal homeostasis are generally prompt and complete upon discontinuation of the drug. Infrequently, signs and symptoms of steroid withdrawal may occur, requiring supplemental systemic corticosteroids. Occasionally, a patient may develop a sensitivity reaction to a particular occlusive dressing material or adhesive and a substitute material may be necessary. Children may absorb proportionally larger amounts of topical corticosteroids and thus be more susceptible to systemic toxicity (see PRECAUTIONS: Pediatric Use). If irritation develops, topical corticosteroids should be discontinued and appropriate therapy instituted. In the presence of dermatological infections, the use of an appropriate antifungal or antibacterial agent should be instituted. If a favorable response does not occur promptly, the corticosteroid should be discontinued until the infection has been adequately controlled. This preparation is not for ophthalmic use. Information for the Patient Patients using topical corticosteroids should receive the following information and instructions: 1) This medication is to be used as directed by the physician. It is for dermatologic use only. Avoid contact with the eyes. 2) Patients should be advised not to use this medication for any disorder other than for which it was prescribed. This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda 4 3) The treated skin area should not be bandaged or otherwise covered or wrapped as to be occlusive unless directed by the physician. 4) Patients should report any signs of local adverse reactions especially under occlusive dressing. 5) Parents of pediatric patients should be advised not to use tight-fitting diapers or plastic pants on a child being treated in the diaper area, as these garments may constitute occlusive dressings. Laboratory Tests A urinary free cortisol test and ACTH stimulation test may be helpful in evaluating HPA axis suppression. Carcinogenesis, Mutagenesis, and Impairment of Fertility Long-term animal studies have not been performed to evaluate the carcinogenic potential or the effect on fertility of topical corticosteroids. Studies to determine mutagenicity with prednisolone and hydrocortisone showed negative results. Pregnancy Teratogenic Effects: Category C Corticosteroids are generally teratogenic in laboratory animals when administered systemically at relatively low dosage levels. The more potent corticosteroids have been shown to be teratogenic after dermal application in laboratory animals. There are no adequate and well-controlled studies in pregnant women on teratogenic effects from topically applied corticosteroids. Therefore, topical corticosteroids should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus. Drugs of this class should not be used extensively on pregnant patients, in large amounts, or for prolonged periods of time. Nursing Mothers It is not known whether topical administration of corticosteroids could result in sufficient systemic absorption to produce detectable quantities in breast milk. Systemically administered corticosteroids are secreted into breast milk in quantities not likely to have a deleterious effect on the infant. Nevertheless, caution should be exercised when topical corticosteroids are administered to a nursing woman. This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda 5 Pediatric Use Pediatric patients may demonstrate greater susceptibility to topical corticosteroid- induced HPA axis suppression and Cushing’s syndrome than mature patients because of a larger skin surface area to body weight ratio. HPA axis suppression, Cushing’s syndrome, and intracranial hypertension have been reported in children receiving topical corticosteroids. Manifestations of adrenal suppression in children include linear growth retardation, delayed weight gain, low plasma cortisol levels, and absence of response to ACTH stimulation. Manifestations of intracranial hypertension include bulging fontanelles, headaches, and bilateral papilledema. Administration of topical corticosteroids to children should be limited to the least amount compatible with an effective therapeutic regimen. Chronic corticosteroid therapy may interfere with the growth and development of children. Geriatric Use Clinical studies of 0.1% HALOG OINTMENT did not include sufficient numbers of patients aged 65 years and over to determine whether they respond differently from younger patients. Other reported clinical experience has not identified differences in responses between the elderly and younger patients. In general, dose selection for an elderly patient should be cautious, usually starting at the low end of the dosing range. ADVERSE REACTIONS The following local adverse reactions are reported infrequently with topical corticosteroids, but may occur more frequently with the use of occlusive dressings (reactions are listed in an approximate decreasing order of occurrence): burning, itching, irritation, dryness, folliculitis, hypertrichosis, acneiform eruptions, hypopigmentation, perioral dermatitis, allergic contact dermatitis, maceration of the skin, secondary infection, skin atrophy, striae, and miliaria. OVERDOSAGE Topically applied corticosteroids can be absorbed in sufficient amounts to produce systemic effects (see PRECAUTIONS: General). This label may not be the latest approved by FDA.

Occlusive Dressing Technique Occlusive dressings may be used for the management of psoriasis or other recalcitrant conditions. Apply a thin film of ointment to the lesion, cover with a pliable nonporous film, and seal the edges. If needed, additional moisture may be provided by covering the lesion with a dampened clean cotton cloth before the nonporous film is applied or by briefly wetting the affected area with water immediately prior to applying the medication. The frequency of changing dressings is best determined on an individual basis. It may be convenient to apply HALOG OINTMENT under an occlusive dressing in the evening and to remove the dressing in the morning (i.e., 12-hour occlusion). When utilizing the 12-hour occlusion regimen, additional ointment should be applied, without occlusion, during the day. Reapplication is essential at each dressing change. If an infection develops, the use of occlusive dressings should be discontinued and appropriate antimicrobial therapy instituted.

LODOSYN ® (CARBIDOPA) TABLETS When LODOSYN (Carbidopa) is to be given to carbidopa-naive patients who are being treated with levodopa, the two drugs should be given at the same time, starting with no more than 20 to 25% of the previous daily dosage of levodopa when given without LODOSYN (Carbidopa). At least twelve hours should elapse between the last dose of levodopa and initiation of therapy with LODOSYN (Carbidopa) and levodopa. See the WARNINGS and DOSAGE AND ADMINISTRATION sections before initiating therapy. DESCRIPTION Carbidopa, an inhibitor of aromatic amino acid decarboxylation, is a white, crystalline compound, slightly soluble in water, with a molecular weight of 244.3. It is designated chemically as (–)-L-α-hydrazino-α-methyl-β-(3,4-dihydroxybenzene) propanoic acid monohydrate. Its empirical formula is C10H14N2O4•H2O and its structural formula is: structural formula LODOSYN (Carbidopa) tablets contain 25 mg of carbidopa. Inactive ingredients are cellulose,FD&C Yellow 6, magnesium stearate and starch. Tablet content is expressed in terms of anhydrous carbidopa which has a molecular weight of 226.3. CLINICAL PHARMACOLOGY Parkinson’s disease is a progressive, neurodegenerative disorder of the extrapyramidal nervous system affecting the mobility and control of the skeletal muscular system. Its characteristic features include resting tremor, rigidity, and bradykinetic movements. Symptomatic treatments, such as levodopa therapies, may permit the patient better mobility. Reference ID: 3458203 Mechanism of Action Current evidence indicates that symptoms of Parkinson’s disease are related to depletion of dopamine in the corpus striatum. Administration of dopamine is ineffective in the treatment of Parkinson’s disease apparently because it does not cross the blood-brain barrier. However, levodopa, the metabolic precursor of dopamine, does cross the blood- brain barrier, and presumably is converted to dopamine in the brain. This is thought to be the mechanism whereby levodopa relieves symptoms of Parkinson’s disease. Pharmacodynamics When levodopa is administered orally it is rapidly decarboxylated to dopamine in extracerebral tissues so that only a small portion of a given dose is transported unchanged to the central nervous system. For this reason, large doses of levodopa are required for adequate therapeutic effect and these may often be accompanied by nausea and other adverse reactions, some of which are attributable to dopamine formed in extracerebral tissues. The incidence of levodopa-induced nausea and vomiting is less when LODOSYN is used with levodopa than when levodopa is used without LODOSYN. In many patients, this reduction in nausea and vomiting will permit more rapid dosage titration. Carbidopa inhibits decarboxylation of peripheral levodopa. Carbidopa has not been demonstrated to have any overt pharmacodynamic actions in the recommended doses. It does not appear to cross the blood-brain barrier readily and does not affect the metabolism of levodopa within the central nervous system at doses of carbidopa that are recommended for maximum effective inhibition of peripheral decarboxylation of levodopa. Since its decarboxylase-inhibiting activity is limited primarily to extracerebral tissues, administration of carbidopa with levodopa makes more levodopa available for transport to the brain. However, since levodopa and carbidopa compete with certain amino acids for transport across the gut wall, the absorption of levodopa and carbidopa may be impaired in some patients on a high protein diet. Pharmacokinetics Carbidopa reduces the amount of levodopa required to produce a given response by about 75% and, when administered with levodopa, increases both plasma levels and the plasma half-life of levodopa, and decreases plasma and urinary dopamine and homovanillic acid. In clinical pharmacologic studies, simultaneous administration of separate tablets of Reference ID: 3458203 carbidopa and levodopa produced greater urinary excretion of levodopa in proportion to the excretion of dopamine when compared to the two drugs administered at separate times. Supplemental pyridoxine (vitamin B6) can be given to patients when they are receiving LODOSYN and levodopa concomitantly or the fixed combination carbidopa-levodopa or carbidopa-levodopa extended release. Previous reports in the medical literature cautioned that high doses of vitamin B6 should not be taken by patients on levodopa therapy alone because exogenously administered pyridoxine would enhance the metabolism of levodopa to dopamine. The introduction of carbidopa to levodopa therapy, which inhibits the peripheral decarboxylation of levodopa to dopamine, counteracts the metabolic-enhancing effect of pyridoxine. Carbidopa is combined with levodopa in carbidopa-levodopa and carbidopa-levodopa extended release tablets. INDICATIONS AND USAGE LODOSYN is indicated for use with carbidopa-levodopa or with levodopa in the treatment of the symptoms of idiopathic Parkinson’s disease (paralysis agitans), postencephalitic parkinsonism, and symptomatic parkinsonism, which may follow injury to the nervous system by carbon monoxide intoxication and/or manganese intoxication. LODOSYN is for use with carbidopa-levodopa in patients for whom the dosage of carbidopa-levodopa provides less than adequate daily dosage (usually 70 mg daily) of carbidopa. LODOSYN is for use with levodopa in the occasional patient whose dosage requirement of carbidopa and levodopa necessitates separate titration of each medication. LODOSYN is used with carbidopa-levodopa or with levodopa to permit the administration of lower doses of levodopa with reduced nausea and vomiting, more rapid dosage titration, and with a somewhat smoother response. However, patients with markedly irregular (“on-off”) responses to levodopa have not been shown to benefit from the addition of carbidopa. Since carbidopa prevents the reversal of levodopa effects caused by pyridoxine, supplemental pyridoxine (vitamin B6), can be given to patients when they are receiving carbidopa and levodopa concomitantly or as carbidopa-levodopa. Although the administration of LODOSYN permits control of parkinsonism and Parkinson’s disease with much lower doses of levodopa, there is no conclusive evidence at present that Reference ID: 3458203 this is beneficial other than in reducing nausea and vomiting, permitting more rapid titration, and providing a somewhat smoother response to levodopa. Certain patients who responded poorly to levodopa alone have improved when carbidopa and levodopa were given concurrently. This was most likely due to decreased peripheral decarboxylation of levodopa rather than to a primary effect of carbidopa on the peripheral nervous system. Carbidopa has not been shown to enhance the intrinsic efficacy of levodopa. In deciding whether to give LODOSYN with carbidopa-levodopa or with levodopa to patients who have nausea and/or vomiting, the physician should be aware that, while many patients may be expected to improve, some may not. Since one cannot predict which patients are likely to improve, this can only be determined by a trial of therapy. It should be further noted that in controlled trials comparing carbidopa and levodopa with levodopa alone, about half the patients with nausea and/or vomiting on levodopa alone improved spontaneously despite being retained on the same dose of levodopa during the controlled portion of the trial. CONTRAINDICATIONS LODOSYN is contraindicated in patients with known hypersensitivity to any component of this drug. Nonselective monoamine oxidase (MAO) inhibitors are contraindicated for use with levodopa or carbidopa-levodopa combination products with or without LODOSYN. These inhibitors must be discontinued at least two weeks prior to initiating therapy with levodopa. Carbidopa-levodopa or levodopa may be administered concomitantly with the manufacturer’s recommended dose of an MAO inhibitor with selectivity for MAO type B (e.g., selegiline HCl) (see PRECAUTIONS, Drug Interactions). Levodopa or carbidopa-levodopa products, with or without LODOSYN, are contra- indicated in patients with narrow-angle glaucoma. WARNINGS LODOSYN (Carbidopa) has no antiparkinsonian effect when given alone. It is indicated for use with carbidopa-levodopa or levodopa. LODOSYN (Carbidopa) does not decrease adverse reactions due to central effects of levodopa. When LODOSYN (Carbidopa) is to be given to carbidopa-naive patients who are being treated with levodopa alone, the two drugs should be given at the same time. Reference ID: 3458203 At least twelve hours should elapse between the last dose of levodopa and initiation of therapy with LODOSYN (Carbidopa) and levodopa in combination. Start with no more than one-fifth (20%) to one-fourth (25%) of the previous daily dosage of levodopa when given without LODOSYN (Carbidopa). See the DOSAGE AND ADMINISTRATION section before initiating therapy. The addition of LODOSYN with levodopa or carbidopa-levodopa reduces the peripheral effects (nausea, vomiting) due to decarboxylation of levodopa; however, LODOSYN does not decrease the adverse reactions due to the central effects of levodopa. Because LODOSYN permits more levodopa to reach the brain and more dopamine to be formed, certain adverse central nervous system (CNS) effects, e.g., dyskinesias (involuntary movements), may occur at lower dosages and sooner with levodopa in combination with LODOSYN than with levodopa alone. Falling Asleep During Activities of Daily Living and Somnolence Patients taking carbidopa-levodopa products alone or with other dopaminergic drugs have reported suddenly falling asleep without prior warning of sleepiness while engaged in activities of daily living (includes operation of motor vehicles). Some of these episodes resulted in automobile accidents. Although many of these patients reported somnolence while on dopaminergic medications, some did perceive that they had no warning signs, such as excessive drowsiness, and believed that they were alert immediately prior to the event. Some patients reported these events one year after the initiation of treatment. Falling asleep while engaged in activities of daily living usually occurs in patients experiencing pre-existing somnolence, although some patients may not give such a history. For this reason, prescribers should continually reassess patients for drowsiness or sleepiness especially since some of the events occur after the start of treatment. Prescribers should be aware that patients may not acknowledge drowsiness or sleepiness until directly questioned about drowsiness or sleepiness during specific activities. Patients who have already experienced somnolence or an episode of sudden sleep onset should not participate in these activities during treatment with LODOSYN when taking it with other carbidopa-levodopa products. Reference ID: 3458203 Before initiating treatment with LODOSYN, advise patients about the potential to develop drowsiness and ask specifically about factors that may increase the risk for somnolence with LODOSYN such as the use of concomitant sedating medications and the presence of sleep disorders. Consider discontinuing LODOSYN in patients who report significant daytime sleepiness or episodes of falling asleep during activities that require active participation (e.g., conversations, eating, etc.). If treatment with LODOSYN continues, patients should be advised not to drive and to avoid other potentially dangerous activities that might result in harm if the patients become somnolent. There is insufficient information to establish that dose reduction will eliminate episodes of falling asleep while engaged in activities of daily living. Hyperpyrexia and Confusion: Sporadic cases of a symptom complex resembling neuroleptic malignant syndrome (NMS) have been reported in association with dose reductions or withdrawal of certain antiparkinsonian agents such as levodopa, carbidopa-levodopa, or carbidopa-levodopa extended-release. Therefore, patients should be observed carefully when the dosage of levodopa or carbidopa­ levodopa is reduced abruptly or discontinued, especially if the patient is receiving neuroleptics. NMS is an uncommon but life-threatening syndrome characterized by fever or hyperthermia. Neurological findings, including muscle rigidity, involuntary movements, altered consciousness, mental status changes; other disturbances, such as autonomic dysfunction, tachycardia, tachypnea, sweating, hyper- or hypotension; laboratory findings, such as creatine phosphokinase elevation, leukocytosis, myoglobinuria, and increased serum myoglobin, have been reported. The early diagnosis of this condition is important for the appropriate management of these patients. Considering NMS as a possible diagnosis and ruling out other acute illnesses (e.g., pneumonia, systemic infection, etc.) is essential. This may be especially complex if the clinical presentation includes both serious medical illness and untreated or inadequately treated extrapyramidal signs and symptoms (EPS). Other important considerations in the differential Reference ID: 3458203 diagnosis include central anticholinergic toxicity, heat stroke, drug fever, and primary central nervous system (CNS) pathology. The management of NMS should include: 1) intensive symptomatic treatment and medical monitoring and 2) treatment of any concomitant serious medical problems for which specific treatments are available. Dopamine agonists, such as bromocriptine, and muscle relaxants, such as dantrolene, are often used in the treatment of NMS; however, their effectiveness has not been demonstrated in controlled studies. PRECAUTIONS General As with levodopa alone, periodic evaluations of hepatic, hematopoietic, cardiovascular, and renal function are recommended during extended concomitant therapy with LODOSYN and levodopa, or with LODOSYN and carbidopa-levodopa or any combination of these drugs. Impulse Control/Compulsive Behaviors Postmarketing reports suggest that patients treated with anti-Parkinson medications can experience intense urges to gamble, increased sexual urges, intense urges to spend money uncontrollably, binge eating, and other intense urges. Patients may be unable to control these urges while taking one or more of the medications that are used for the treatment of Parkinson’s disease and that increase central dopaminergic tone, including Lodosyn taken with levodopa and carbidopa. In some cases, although not all, these urges were reported to have stopped when the dose of anti-Parkinson medications was reduced or discontinued. Because patients may not recognize these behaviors as abnormal it is important for prescribers to specifically ask patients or their caregivers about the development of new or increased gambling urges, sexual urges, uncontrolled spending or other urges while being treated with Lodosyn. Physicians should consider dose reduction or stopping Lodosyn or levodopa if a patient develops such urges while taking Lodosyn with carbidopa/levodopa. Hallucinations/Psychotic-Like Behavior Reference ID: 3458203 Hallucinations and psychotic like behavior have been reported with dopaminergic medications. In general, hallucinations present shortly after the initiation of therapy and may be responsive to dose reduction in levodopa. Hallucinations may be accompanied by confusion and to a lesser extent sleep disorder (insomnia) and excessive dreaming. LODOSYN when taken with carbidopa-levodopa may have similar effects on thinking and behavior. This abnormal thinking and behavior may present with one or more symptoms, including paranoid ideation, delusions, hallucinations, confusion, psychotic-like behavior, disorientation, aggressive behavior, agitation, and delirium. Ordinarily, patients with a major psychotic disorder should not be treated with LODOSYN and carbidopa-levodopa, because of the risk of exacerbating psychosis. In addition, certain medications used to treat psychosis may exacerbate the symptoms of Parkinson’s disease and may decrease the effectiveness of LODOSYN. Dyskinesia LODOSYN (Carbidopa) may potentiate the dopaminergic side effects of levodopa and may cause or exacerbate preexisting dyskinesia. Depression Patients treated with LODOSYN and carbidopa-levodopa should be observed carefully for the development of depression with concomitant suicidal tendencies. Melanoma Epidemiological studies have shown that patients with Parkinson’s disease have a higher risk (2­ to approximately 6-fold higher) of developing melanoma than the general population. Whether the observed increased risk was due to Parkinson’s disease or other factors, such as drugs used to treat Parkinson’s disease, is unclear. For the reasons stated above, patients and providers are advised to monitor for melanomas frequently and on a regular basis when using LODOSYN tablets for Parkinson’s disease. Reference ID: 3458203 Ideally, periodic skin examinations should be performed by appropriately qualified individuals (e.g., dermatologists). Information for Patients It is important that LODOSYN with levodopa be taken at regular intervals according to the schedule outlined by the health care provider. Caution patients not to change the prescribed dosage regimen and not to add any additional antiparkinson medications, including other carbidopa-levodopa preparations without first consulting a physician. Advise patients that sometimes a ‘wearing-off’ effect may occur at the end of the dosing interval. Tell patients to notify the prescriber if such response poses a problem to lifestyle. Patients should be advised that occasionally dark color (red, brown, or black) may appear in saliva, urine, or sweat after ingestion of LODOSYN and levodopa. Although the color appears to be clinically insignificant, garments may become discolored. The patient should be advised that a change in diet to foods that are high in protein may delay the absorption of levodopa and may reduce the amount taken up in the circulation. Excessive acidity also delays stomach emptying thus delaying the absorption of levodopa. Iron salts (such as in multivitamin tablets) may also reduce the amount of levodopa available in the body. The above factors may reduce the clinical effectiveness of the LODOSYN and levodopa therapy. Alert patients to the possibility of sudden onset of sleep during daily activities, in some cases without awareness or warning signs, when they are taking dopaminergic agents, including levodopa. Advise patients to exercise caution while driving or operating machinery and that if they have experience somnolence and/or sudden sleep onset, they must refrain from these activities. (See WARNINGS, Falling Asleep During Activities of Daily Living and Somnolence General.) There have been reports of patients experiencing intense urges to gamble, increased sexual urges, and other intense urges, and the inability to control these urges while taking one or more of the medications that increase central dopaminergic tone and that are generally used for the treatment Reference ID: 3458203 of Parkinson’s disease, including LODOSYN and levodopa. Although it is not proven that the medications caused these events, these urges were reported to have stopped in some cases when the dose was reduced or the medication was stopped. Prescribers should ask patients about the development of new or increased gambling urges, sexual urges, or other intense urges while taking LODOSYN and levodopa. Physicians should consider dose reduction or stopping Lodosyn and levodopa if a patient develops such urges while taking Lodosyn with carbidopa/levodopa (See PRECAUTIONS, Impulse Control/Compulsive Behaviors). Laboratory Tests Abnormalities in laboratory tests may include elevations of liver function tests such as alkaline phosphatase, SGOT (AST), SGPT (ALT), lactic dehydrogenase, and bilirubin. Abnormalities in blood urea nitrogen and positive Coombs test have also been reported. Commonly, levels of blood urea nitrogen, creatinine, and uric acid are lower during concomitant administration of carbidopa and levodopa than with levodopa alone. Levodopa and carbidopa-levodopa combination products may cause a false-positive reaction for urinary ketone bodies when a test tape is used for determination of ketonuria. This reaction will not be altered by boiling the urine specimen. False-negative tests may result with the use of glucose-oxidase methods of testing for glucosuria. Drug Interactions Caution should be exercised when the following drugs are administered concomitantly with LODOSYN (Carbidopa) given with levodopa or carbidopa-levodopa fixed dose combination products. Symptomatic postural hypotension has occurred when LODOSYN, given with levodopa or carbidopa-levodopa combination products, was added to the treatment of a patient receiving antihypertensive drugs. Therefore, when therapy with LODOSYN, given with or without levodopa or carbidopa-levodopa combination products, is started, dosage adjustment of the antihypertensive drug may be required. Reference ID: 3458203 For patients receiving monoamine oxidase inhibitors (Type A or B), see CONTRAINDICATIONS. Concomitant therapy with selegiline or rasigiline and LODOSYN and carbidopa-levodopa may be associated with severe orthostatic hypotension not attributable to carbidopa-levodopa alone (see CONTRAINDICATIONS). There have been rare reports of adverse reactions, including hypertension and dyskinesia, resulting from the concomitant use of tricyclic antidepressants and carbidopa-levodopa preparations. Dopamine D2 receptor antagonists (e.g., phenothiazines, butyrophenones, risperidone) and isoniazid may reduce the therapeutic effects of levodopa. In addition, the beneficial effects of levodopa in Parkinson’s disease have been reported to be reversed by phenytoin and papaverine. Patients taking these drugs with LODOSYN and levodopa or carbidopa-levodopa combination products should be carefully observed for loss of therapeutic response LODOSYN and iron salts or multi vitamins containing iron salts should be co administered with caution. Iron salts c a n f or m c he l a t e s w i t h l e vod opa a nd c a r bi dopa a nd c ons e que nt l y reduce the bioavailability of carbidopa and levodopa. Although metoclopramide may increase the bioavailability of levodopa by increasing gastric emptying, metoclopramide may also adversely affect disease control by its dopamine receptor antagonistic properties. Carcinogenesis, Mutagenesis, Impairment of Fertility Carcinogenesis There were no significant differences between treated and control rats with respect to mortality or neoplasia in a 96-week study of carbidopa at oral doses of 25, 45, or 135 mg/kg/day. Combinations of carbidopa and levodopa (10-20, 10-50, 10-100 mg/kg/day) were given orally to rats for 106 weeks. No effect on mortality or incidence and type of neoplasia was seen when compared to concurrent controls. Mutagenesis Mutagenicity studies have not been performed with either carbidopa or the combination of carbidopa and levodopa. Fertility Reference ID: 3458203 Carbidopa had no effect on the mating performance, fertility, or survival of the young when administered orally to rats at doses of 30, 60, or 120 mg/kg/day. The highest dose caused a moderate decrease in body weight gain in males. The administration of carbidopa-levodopa at dose levels of 10-20, 10-50, or 10-100 mg/kg/day did not adversely affect the fertility of male or female rats, their reproductive performance, or the growth and survival of the young. Pregnancy Pregnancy Category C: There are no adequate and well-controlled studies with LODOSYN in pregnant women. It has been reported from individual cases that levodopa crosses the human placental barrier, enters the fetus, and is metabolized. Carbidopa concentrations in fetal tissue appeared to be minimal. LODOSYN should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus. Carbidopa, at doses as high as 120 mg/kg/day, was without teratogenic effects in the mouse or rabbit. In the rabbit, but not in the mouse, carbidopa-levodopa produced visceral anomalies, similar to those seen with levodopa alone, at approximately 7 times the maximum recommended human dose. The teratogenic effect of levodopa in rabbits was unchanged by the concomitant administration of carbidopa. Nursing Mothers It is not known whether carbidopa is excreted in human milk. Because many drugs are excreted in human milk, and because of their potential for serious adverse reactions in nursing infants, a decision should be made whether to discontinue nursing or to discontinue the drug, taking into account the importance of the drug to the nursing woman. Pediatric Use Safety and effectiveness in pediatric patients have not been established, and use of the drug in patients below the age of 18 is not recommended. Reference ID: 3458203 Geriatric Use Clinical studies of LODOSYN did not include sufficient numbers of subjects aged 65 and over to determine whether they respond differently from younger subjects. Other clinical experience has not identified differences in responses between the elderly and younger patients. In general, dose selection for an elderly patient should be cautious, usually starting at the low end of the dosing range, reflecting the greater frequency of decreased hepatic, renal, or cardiac function, and concomitant disease and other drug therapy. ADVERSE REACTIONS Carbidopa has not been demonstrated to have any overt pharmacodynamic actions in the recommended doses. The only adverse reactions that have been observed have been with concomitant use of carbidopa with other drugs such as levodopa, and with carbidopa­ levodopa combination products. When LODOSYN is administered concomitantly with levodopa or carbidopa-levodopa combination products, the most common adverse reactions have included dyskinesias such as choreiform, dystonic, and other involuntary movements, and nausea. Other adverse reactions reported with LODOSYN when administered concomitantly with levodopa alone or carbidopa-levodopa combination products were psychotic episodes including delusions, hallucinations, and paranoid ideation, depression with or without development of suicidal tendencies, and dementia. Convulsions also have occurred; however, a causal relationship with concomitant use of LODOSYN and levodopa has not been established. The following other adverse reactions have been reported with levodopa and carbidopa­ levodopa combination products. These same adverse reactions may also occur when LODOSYN is administered with these products. Body as a Whole: abdominal pain and distress, asthenia, chest pain, fatigue. Cardiovascular: cardiac irregularities, hypertension, myocardial infarction, hypotension including orthostatic hypotension, palpitation, phlebitis, syncope. Gastrointestinal: anorexia, bruxism, burning sensation of the tongue, constipation, dark saliva, development of duodenal ulcer, diarrhea, dry mouth, dyspepsia, dysphagia, flatulence, gastrointestinal bleeding, gastrointestinal pain, heartburn, hiccups, sialorrhea, taste alterations, vomiting. Reference ID: 3458203 Hematologic: hemolytic and non-hemolytic anemia, leukopenia, thrombocytopenia, agranulocytosis. Hypersensitivity: angioedema, urticaria, pruritus, Henoch-Schonlein purpura, bullous lesions (including pemphigus-like reactions). Metabolic: edema, weight gain, weight loss. Musculoskeletal: back pain, leg pain, muscle cramps, shoulder pain. Nervous System/Psychiatric: Psychotic episodes including delusions, hallucinations and paranoid ideation, neuroleptic malignant syndrome (NMS, see WARNINGS), bradykinetic episodes (“on-off” phenomenon), confusion, agitation, dizziness, somnolence, dream abnormalities including nightmares, insomnia, paresthesia, headache, depression with or without development of suicidal tendencies, dementia, pathological gambling, increased libido including hypersexuality, impulse control symptoms. Convulsions also have occurred; however, a causal relationship with LODOSYN and levodopa, has not been established. Respiratory: upper respiratory infection, dyspnea, pharyngeal pain, cough. Skin: flushing, increased sweating, malignant melanoma (see also CONTRAINDICATIONS), rash, alopecia, dark sweat. Special Senses: oculogyric crises, diplopia, blurred vision, dilated pupils. Urogenital: dark urine, priapism, urinary frequency, urinary incontinence, urinary retention, urinary tract infection. Laboratory Tests: abnormalities in alkaline phosphatase, SGOT (AST), SGPT (ALT), lactic dehydrogenase, bilirubin, blood urea nitrogen (BUN), Coombs test; elevated serum glucose; decreased hemoglobin and hematocrit; decreased white blood cell count and serum potassium; increased serum creatinine and uric acid; white blood cells, bacteria and blood in the urine; protein and glucose in the urine. Miscellaneous: bizarre breathing patterns, faintness, hoarseness, hot flashes, malaise, neuroleptic malignant syndrome, sense of stimulation. OVERDOSAGE No reports of overdose with LODOSYN have been received. Management of overdosage with carbidopa is the same as that with levodopa or carbidopa-levodopa preparations. Reference ID: 3458203 In the event of overdosage, general supportive measures should be employed, along with immediate gastric lavage. Intravenous fluids should be administered judiciously, and an adequate airway maintained. Electrocardiographic monitoring should be instituted and the patient carefully observed for the development of arrhythmias; if required, appropriate antiarrhythmic therapy should be given. The possibility that the patient may have taken other drugs as well as LODOSYN should be taken into consideration. To date, no experience has been reported with dialysis; hence, its value in overdosage is not known. Pyridoxine is not effective in reversing the actions of LODOSYN. Based on studies in which high doses of levodopa and/or carbidopa were administered, a significant proportion of rats and mice given single oral doses of levodopa of approximately 1500-2000 mg/kg are expected to die. A significant proportion of infant rats of both sexes are expected to die at a dose of 800 mg/kg. A significant proportion of rats are expected to die after treatment with similar doses of carbidopa. The addition of carbidopa in a 1:10 ratio with levodopa increases the dose at which a significant proportion of mice are expected to die to 3360 mg/kg. DOSAGE AND ADMINISTRATION Whether given with carbidopa-levodopa or with levodopa, the optimal daily dose of LODOSYN must be determined by careful titration. Most patients respond to a 1:10 proportion of carbidopa and levodopa, provided the daily dosage of carbidopa is 70 mg or more a day. The maximum daily dosage of carbidopa should not exceed 200 mg, since clinical experience with larger dosages is limited. If the patient is taking carbidopa-levodopa, the amount of carbidopa in carbidopa-levodopa should be considered when calculating the total amount of LODOSYN to be administered each day. Patients Receiving Carbidopa-Levodopa Who Require Additional Carbidopa Some patients taking carbidopa-levodopa may not have adequate reduction in nausea and vomiting when the dosage of carbidopa is less than 70 mg a day, and the dosage of levodopa is less than 700 mg a day. When these patients are taking carbidopa-levodopa, 25 mg of LODOSYN may be given with the first dose of carbidopa-levodopa each day. Additional doses of 12.5 mg or 25 mg may be given during the day with each dose of carbidopa­ levodopa. LODOSYN may be given with any dose carbidopa-levodopa as required for optimum therapeutic response. The maximum daily dosage of carbidopa, given as LODOSYN and as carbidopa- levodopa), should not exceed 200 mg. Patients Requiring Individual Titration of Carbidopa and Reference ID: 3458203 Levodopa Dosage Although carbidopa-levodopa is the most frequently used of carbidopa and levodopa administration, there may be an occasional patient who requires individually titrated doses of these two drugs. In these patients, LODOSYN (carbidopa) should be initiated at a dosage of 25 mg three or four times a day. The two drugs should be given at the same time, starting with no more than one-fifth (20%) to one-fourth (25%) of the previous or recommended daily dosage of levodopa when given without LODOSYN (Carbidopa). In patients already receiving levodopa therapy, at least twelve hours should elapse between the last dose of levodopa and initiation of therapy with LODOSYN (Carbidopa) and levodopa. A convenient way to initiate therapy in these patients is in the morning following a night when the patient has not taken levodopa for at least twelve hours. Health care providers who prescribe separate doses of LODOSYN and levodopa should be thoroughly familiar with the directions for use of each drug. Dosage Adjustment Dosage of LODOSYN may be adjusted by adding or omitting one-half or one tablet a day. Because both therapeutic and adverse responses occur more rapidly with combined therapy than when only levodopa is given, patients should be monitored closely during the dose adjustment period. Specifically, involuntary movements will occur more rapidly when LODOSYN and levodopa are given concomitantly than when levodopa is given without LODOSYN. The occurrence of involuntary movements may require dosage reduction. Blepharospasm may be a useful early sign of excess dosage in some patients. Current evidence indicates other standard antiparkinsonian drugs may be continued while carbidopa and levodopa are being administered. However, the dosage of such other standard antiparkinsonian drugs may require adjustment. Interruption of Therapy Sporadic cases of hyperpyrexia and confusion have been associated with dose reductions and withdrawal of carbidopa-Levodopa) or carbidopa-levodopa Extended Release. Patients should be observed carefully if abrupt reduction or discontinuation of carbidopa-levodopa or carbidopa-levodopa Extended-Release is required, especially if the patient is receiving neuroleptics. (See WARNINGS.) If general anesthesia is required, therapy may be continued as long as the patient is Reference ID: 3458203 permitted to take fluids and medication by mouth. When therapy is interrupted temporarily, the patient should be observed for symptoms resembling NMS, and the usual daily dosage may be resumed as soon as the patient is able to take medication orally.

LODOSYN ® (CARBIDOPA) TABLETS When LODOSYN (Carbidopa) is to be given to carbidopa-naive patients who are being treated with levodopa, the two drugs should be given at the same time, starting with no more than 20 to 25% of the previous daily dosage of levodopa when given without LODOSYN (Carbidopa). At least twelve hours should elapse between the last dose of levodopa and initiation of therapy with LODOSYN (Carbidopa) and levodopa. See the WARNINGS and DOSAGE AND ADMINISTRATION sections before initiating therapy. DESCRIPTION Carbidopa, an inhibitor of aromatic amino acid decarboxylation, is a white, crystalline compound, slightly soluble in water, with a molecular weight of 244.3. It is designated chemically as (–)-L-α-hydrazino-α-methyl-β-(3,4-dihydroxybenzene) propanoic acid monohydrate. Its empirical formula is C10H14N2O4•H2O and its structural formula is: structural formula LODOSYN (Carbidopa) tablets contain 25 mg of carbidopa. Inactive ingredients are cellulose,FD&C Yellow 6, magnesium stearate and starch. Tablet content is expressed in terms of anhydrous carbidopa which has a molecular weight of 226.3. CLINICAL PHARMACOLOGY Parkinson’s disease is a progressive, neurodegenerative disorder of the extrapyramidal nervous system affecting the mobility and control of the skeletal muscular system. Its characteristic features include resting tremor, rigidity, and bradykinetic movements. Symptomatic treatments, such as levodopa therapies, may permit the patient better mobility. Reference ID: 3458203 Mechanism of Action Current evidence indicates that symptoms of Parkinson’s disease are related to depletion of dopamine in the corpus striatum. Administration of dopamine is ineffective in the treatment of Parkinson’s disease apparently because it does not cross the blood-brain barrier. However, levodopa, the metabolic precursor of dopamine, does cross the blood- brain barrier, and presumably is converted to dopamine in the brain. This is thought to be the mechanism whereby levodopa relieves symptoms of Parkinson’s disease. Pharmacodynamics When levodopa is administered orally it is rapidly decarboxylated to dopamine in extracerebral tissues so that only a small portion of a given dose is transported unchanged to the central nervous system. For this reason, large doses of levodopa are required for adequate therapeutic effect and these may often be accompanied by nausea and other adverse reactions, some of which are attributable to dopamine formed in extracerebral tissues. The incidence of levodopa-induced nausea and vomiting is less when LODOSYN is used with levodopa than when levodopa is used without LODOSYN. In many patients, this reduction in nausea and vomiting will permit more rapid dosage titration. Carbidopa inhibits decarboxylation of peripheral levodopa. Carbidopa has not been demonstrated to have any overt pharmacodynamic actions in the recommended doses. It does not appear to cross the blood-brain barrier readily and does not affect the metabolism of levodopa within the central nervous system at doses of carbidopa that are recommended for maximum effective inhibition of peripheral decarboxylation of levodopa. Since its decarboxylase-inhibiting activity is limited primarily to extracerebral tissues, administration of carbidopa with levodopa makes more levodopa available for transport to the brain. However, since levodopa and carbidopa compete with certain amino acids for transport across the gut wall, the absorption of levodopa and carbidopa may be impaired in some patients on a high protein diet. Pharmacokinetics Carbidopa reduces the amount of levodopa required to produce a given response by about 75% and, when administered with levodopa, increases both plasma levels and the plasma half-life of levodopa, and decreases plasma and urinary dopamine and homovanillic acid. In clinical pharmacologic studies, simultaneous administration of separate tablets of Reference ID: 3458203 carbidopa and levodopa produced greater urinary excretion of levodopa in proportion to the excretion of dopamine when compared to the two drugs administered at separate times. Supplemental pyridoxine (vitamin B6) can be given to patients when they are receiving LODOSYN and levodopa concomitantly or the fixed combination carbidopa-levodopa or carbidopa-levodopa extended release. Previous reports in the medical literature cautioned that high doses of vitamin B6 should not be taken by patients on levodopa therapy alone because exogenously administered pyridoxine would enhance the metabolism of levodopa to dopamine. The introduction of carbidopa to levodopa therapy, which inhibits the peripheral decarboxylation of levodopa to dopamine, counteracts the metabolic-enhancing effect of pyridoxine. Carbidopa is combined with levodopa in carbidopa-levodopa and carbidopa-levodopa extended release tablets. INDICATIONS AND USAGE LODOSYN is indicated for use with carbidopa-levodopa or with levodopa in the treatment of the symptoms of idiopathic Parkinson’s disease (paralysis agitans), postencephalitic parkinsonism, and symptomatic parkinsonism, which may follow injury to the nervous system by carbon monoxide intoxication and/or manganese intoxication. LODOSYN is for use with carbidopa-levodopa in patients for whom the dosage of carbidopa-levodopa provides less than adequate daily dosage (usually 70 mg daily) of carbidopa. LODOSYN is for use with levodopa in the occasional patient whose dosage requirement of carbidopa and levodopa necessitates separate titration of each medication. LODOSYN is used with carbidopa-levodopa or with levodopa to permit the administration of lower doses of levodopa with reduced nausea and vomiting, more rapid dosage titration, and with a somewhat smoother response. However, patients with markedly irregular (“on-off”) responses to levodopa have not been shown to benefit from the addition of carbidopa. Since carbidopa prevents the reversal of levodopa effects caused by pyridoxine, supplemental pyridoxine (vitamin B6), can be given to patients when they are receiving carbidopa and levodopa concomitantly or as carbidopa-levodopa. Although the administration of LODOSYN permits control of parkinsonism and Parkinson’s disease with much lower doses of levodopa, there is no conclusive evidence at present that Reference ID: 3458203 this is beneficial other than in reducing nausea and vomiting, permitting more rapid titration, and providing a somewhat smoother response to levodopa. Certain patients who responded poorly to levodopa alone have improved when carbidopa and levodopa were given concurrently. This was most likely due to decreased peripheral decarboxylation of levodopa rather than to a primary effect of carbidopa on the peripheral nervous system. Carbidopa has not been shown to enhance the intrinsic efficacy of levodopa. In deciding whether to give LODOSYN with carbidopa-levodopa or with levodopa to patients who have nausea and/or vomiting, the physician should be aware that, while many patients may be expected to improve, some may not. Since one cannot predict which patients are likely to improve, this can only be determined by a trial of therapy. It should be further noted that in controlled trials comparing carbidopa and levodopa with levodopa alone, about half the patients with nausea and/or vomiting on levodopa alone improved spontaneously despite being retained on the same dose of levodopa during the controlled portion of the trial. CONTRAINDICATIONS LODOSYN is contraindicated in patients with known hypersensitivity to any component of this drug. Nonselective monoamine oxidase (MAO) inhibitors are contraindicated for use with levodopa or carbidopa-levodopa combination products with or without LODOSYN. These inhibitors must be discontinued at least two weeks prior to initiating therapy with levodopa. Carbidopa-levodopa or levodopa may be administered concomitantly with the manufacturer’s recommended dose of an MAO inhibitor with selectivity for MAO type B (e.g., selegiline HCl) (see PRECAUTIONS, Drug Interactions). Levodopa or carbidopa-levodopa products, with or without LODOSYN, are contra- indicated in patients with narrow-angle glaucoma. WARNINGS LODOSYN (Carbidopa) has no antiparkinsonian effect when given alone. It is indicated for use with carbidopa-levodopa or levodopa. LODOSYN (Carbidopa) does not decrease adverse reactions due to central effects of levodopa. When LODOSYN (Carbidopa) is to be given to carbidopa-naive patients who are being treated with levodopa alone, the two drugs should be given at the same time. Reference ID: 3458203 At least twelve hours should elapse between the last dose of levodopa and initiation of therapy with LODOSYN (Carbidopa) and levodopa in combination. Start with no more than one-fifth (20%) to one-fourth (25%) of the previous daily dosage of levodopa when given without LODOSYN (Carbidopa). See the DOSAGE AND ADMINISTRATION section before initiating therapy. The addition of LODOSYN with levodopa or carbidopa-levodopa reduces the peripheral effects (nausea, vomiting) due to decarboxylation of levodopa; however, LODOSYN does not decrease the adverse reactions due to the central effects of levodopa. Because LODOSYN permits more levodopa to reach the brain and more dopamine to be formed, certain adverse central nervous system (CNS) effects, e.g., dyskinesias (involuntary movements), may occur at lower dosages and sooner with levodopa in combination with LODOSYN than with levodopa alone. Falling Asleep During Activities of Daily Living and Somnolence Patients taking carbidopa-levodopa products alone or with other dopaminergic drugs have reported suddenly falling asleep without prior warning of sleepiness while engaged in activities of daily living (includes operation of motor vehicles). Some of these episodes resulted in automobile accidents. Although many of these patients reported somnolence while on dopaminergic medications, some did perceive that they had no warning signs, such as excessive drowsiness, and believed that they were alert immediately prior to the event. Some patients reported these events one year after the initiation of treatment. Falling asleep while engaged in activities of daily living usually occurs in patients experiencing pre-existing somnolence, although some patients may not give such a history. For this reason, prescribers should continually reassess patients for drowsiness or sleepiness especially since some of the events occur after the start of treatment. Prescribers should be aware that patients may not acknowledge drowsiness or sleepiness until directly questioned about drowsiness or sleepiness during specific activities. Patients who have already experienced somnolence or an episode of sudden sleep onset should not participate in these activities during treatment with LODOSYN when taking it with other carbidopa-levodopa products. Reference ID: 3458203 Before initiating treatment with LODOSYN, advise patients about the potential to develop drowsiness and ask specifically about factors that may increase the risk for somnolence with LODOSYN such as the use of concomitant sedating medications and the presence of sleep disorders. Consider discontinuing LODOSYN in patients who report significant daytime sleepiness or episodes of falling asleep during activities that require active participation (e.g., conversations, eating, etc.). If treatment with LODOSYN continues, patients should be advised not to drive and to avoid other potentially dangerous activities that might result in harm if the patients become somnolent. There is insufficient information to establish that dose reduction will eliminate episodes of falling asleep while engaged in activities of daily living. Hyperpyrexia and Confusion: Sporadic cases of a symptom complex resembling neuroleptic malignant syndrome (NMS) have been reported in association with dose reductions or withdrawal of certain antiparkinsonian agents such as levodopa, carbidopa-levodopa, or carbidopa-levodopa extended-release. Therefore, patients should be observed carefully when the dosage of levodopa or carbidopa­ levodopa is reduced abruptly or discontinued, especially if the patient is receiving neuroleptics. NMS is an uncommon but life-threatening syndrome characterized by fever or hyperthermia. Neurological findings, including muscle rigidity, involuntary movements, altered consciousness, mental status changes; other disturbances, such as autonomic dysfunction, tachycardia, tachypnea, sweating, hyper- or hypotension; laboratory findings, such as creatine phosphokinase elevation, leukocytosis, myoglobinuria, and increased serum myoglobin, have been reported. The early diagnosis of this condition is important for the appropriate management of these patients. Considering NMS as a possible diagnosis and ruling out other acute illnesses (e.g., pneumonia, systemic infection, etc.) is essential. This may be especially complex if the clinical presentation includes both serious medical illness and untreated or inadequately treated extrapyramidal signs and symptoms (EPS). Other important considerations in the differential Reference ID: 3458203 diagnosis include central anticholinergic toxicity, heat stroke, drug fever, and primary central nervous system (CNS) pathology. The management of NMS should include: 1) intensive symptomatic treatment and medical monitoring and 2) treatment of any concomitant serious medical problems for which specific treatments are available. Dopamine agonists, such as bromocriptine, and muscle relaxants, such as dantrolene, are often used in the treatment of NMS; however, their effectiveness has not been demonstrated in controlled studies. PRECAUTIONS General As with levodopa alone, periodic evaluations of hepatic, hematopoietic, cardiovascular, and renal function are recommended during extended concomitant therapy with LODOSYN and levodopa, or with LODOSYN and carbidopa-levodopa or any combination of these drugs. Impulse Control/Compulsive Behaviors Postmarketing reports suggest that patients treated with anti-Parkinson medications can experience intense urges to gamble, increased sexual urges, intense urges to spend money uncontrollably, binge eating, and other intense urges. Patients may be unable to control these urges while taking one or more of the medications that are used for the treatment of Parkinson’s disease and that increase central dopaminergic tone, including Lodosyn taken with levodopa and carbidopa. In some cases, although not all, these urges were reported to have stopped when the dose of anti-Parkinson medications was reduced or discontinued. Because patients may not recognize these behaviors as abnormal it is important for prescribers to specifically ask patients or their caregivers about the development of new or increased gambling urges, sexual urges, uncontrolled spending or other urges while being treated with Lodosyn. Physicians should consider dose reduction or stopping Lodosyn or levodopa if a patient develops such urges while taking Lodosyn with carbidopa/levodopa. Hallucinations/Psychotic-Like Behavior Reference ID: 3458203 Hallucinations and psychotic like behavior have been reported with dopaminergic medications. In general, hallucinations present shortly after the initiation of therapy and may be responsive to dose reduction in levodopa. Hallucinations may be accompanied by confusion and to a lesser extent sleep disorder (insomnia) and excessive dreaming. LODOSYN when taken with carbidopa-levodopa may have similar effects on thinking and behavior. This abnormal thinking and behavior may present with one or more symptoms, including paranoid ideation, delusions, hallucinations, confusion, psychotic-like behavior, disorientation, aggressive behavior, agitation, and delirium. Ordinarily, patients with a major psychotic disorder should not be treated with LODOSYN and carbidopa-levodopa, because of the risk of exacerbating psychosis. In addition, certain medications used to treat psychosis may exacerbate the symptoms of Parkinson’s disease and may decrease the effectiveness of LODOSYN. Dyskinesia LODOSYN (Carbidopa) may potentiate the dopaminergic side effects of levodopa and may cause or exacerbate preexisting dyskinesia. Depression Patients treated with LODOSYN and carbidopa-levodopa should be observed carefully for the development of depression with concomitant suicidal tendencies. Melanoma Epidemiological studies have shown that patients with Parkinson’s disease have a higher risk (2­ to approximately 6-fold higher) of developing melanoma than the general population. Whether the observed increased risk was due to Parkinson’s disease or other factors, such as drugs used to treat Parkinson’s disease, is unclear. For the reasons stated above, patients and providers are advised to monitor for melanomas frequently and on a regular basis when using LODOSYN tablets for Parkinson’s disease. Reference ID: 3458203 Ideally, periodic skin examinations should be performed by appropriately qualified individuals (e.g., dermatologists). Information for Patients It is important that LODOSYN with levodopa be taken at regular intervals according to the schedule outlined by the health care provider. Caution patients not to change the prescribed dosage regimen and not to add any additional antiparkinson medications, including other carbidopa-levodopa preparations without first consulting a physician. Advise patients that sometimes a ‘wearing-off’ effect may occur at the end of the dosing interval. Tell patients to notify the prescriber if such response poses a problem to lifestyle. Patients should be advised that occasionally dark color (red, brown, or black) may appear in saliva, urine, or sweat after ingestion of LODOSYN and levodopa. Although the color appears to be clinically insignificant, garments may become discolored. The patient should be advised that a change in diet to foods that are high in protein may delay the absorption of levodopa and may reduce the amount taken up in the circulation. Excessive acidity also delays stomach emptying thus delaying the absorption of levodopa. Iron salts (such as in multivitamin tablets) may also reduce the amount of levodopa available in the body. The above factors may reduce the clinical effectiveness of the LODOSYN and levodopa therapy. Alert patients to the possibility of sudden onset of sleep during daily activities, in some cases without awareness or warning signs, when they are taking dopaminergic agents, including levodopa. Advise patients to exercise caution while driving or operating machinery and that if they have experience somnolence and/or sudden sleep onset, they must refrain from these activities. (See WARNINGS, Falling Asleep During Activities of Daily Living and Somnolence General.) There have been reports of patients experiencing intense urges to gamble, increased sexual urges, and other intense urges, and the inability to control these urges while taking one or more of the medications that increase central dopaminergic tone and that are generally used for the treatment Reference ID: 3458203 of Parkinson’s disease, including LODOSYN and levodopa. Although it is not proven that the medications caused these events, these urges were reported to have stopped in some cases when the dose was reduced or the medication was stopped. Prescribers should ask patients about the development of new or increased gambling urges, sexual urges, or other intense urges while taking LODOSYN and levodopa. Physicians should consider dose reduction or stopping Lodosyn and levodopa if a patient develops such urges while taking Lodosyn with carbidopa/levodopa (See PRECAUTIONS, Impulse Control/Compulsive Behaviors). Laboratory Tests Abnormalities in laboratory tests may include elevations of liver function tests such as alkaline phosphatase, SGOT (AST), SGPT (ALT), lactic dehydrogenase, and bilirubin. Abnormalities in blood urea nitrogen and positive Coombs test have also been reported. Commonly, levels of blood urea nitrogen, creatinine, and uric acid are lower during concomitant administration of carbidopa and levodopa than with levodopa alone. Levodopa and carbidopa-levodopa combination products may cause a false-positive reaction for urinary ketone bodies when a test tape is used for determination of ketonuria. This reaction will not be altered by boiling the urine specimen. False-negative tests may result with the use of glucose-oxidase methods of testing for glucosuria. Drug Interactions Caution should be exercised when the following drugs are administered concomitantly with LODOSYN (Carbidopa) given with levodopa or carbidopa-levodopa fixed dose combination products. Symptomatic postural hypotension has occurred when LODOSYN, given with levodopa or carbidopa-levodopa combination products, was added to the treatment of a patient receiving antihypertensive drugs. Therefore, when therapy with LODOSYN, given with or without levodopa or carbidopa-levodopa combination products, is started, dosage adjustment of the antihypertensive drug may be required. Reference ID: 3458203 For patients receiving monoamine oxidase inhibitors (Type A or B), see CONTRAINDICATIONS. Concomitant therapy with selegiline or rasigiline and LODOSYN and carbidopa-levodopa may be associated with severe orthostatic hypotension not attributable to carbidopa-levodopa alone (see CONTRAINDICATIONS). There have been rare reports of adverse reactions, including hypertension and dyskinesia, resulting from the concomitant use of tricyclic antidepressants and carbidopa-levodopa preparations. Dopamine D2 receptor antagonists (e.g., phenothiazines, butyrophenones, risperidone) and isoniazid may reduce the therapeutic effects of levodopa. In addition, the beneficial effects of levodopa in Parkinson’s disease have been reported to be reversed by phenytoin and papaverine. Patients taking these drugs with LODOSYN and levodopa or carbidopa-levodopa combination products should be carefully observed for loss of therapeutic response LODOSYN and iron salts or multi vitamins containing iron salts should be co administered with caution. Iron salts c a n f or m c he l a t e s w i t h l e vod opa a nd c a r bi dopa a nd c ons e que nt l y reduce the bioavailability of carbidopa and levodopa. Although metoclopramide may increase the bioavailability of levodopa by increasing gastric emptying, metoclopramide may also adversely affect disease control by its dopamine receptor antagonistic properties. Carcinogenesis, Mutagenesis, Impairment of Fertility Carcinogenesis There were no significant differences between treated and control rats with respect to mortality or neoplasia in a 96-week study of carbidopa at oral doses of 25, 45, or 135 mg/kg/day. Combinations of carbidopa and levodopa (10-20, 10-50, 10-100 mg/kg/day) were given orally to rats for 106 weeks. No effect on mortality or incidence and type of neoplasia was seen when compared to concurrent controls. Mutagenesis Mutagenicity studies have not been performed with either carbidopa or the combination of carbidopa and levodopa. Fertility Reference ID: 3458203 Carbidopa had no effect on the mating performance, fertility, or survival of the young when administered orally to rats at doses of 30, 60, or 120 mg/kg/day. The highest dose caused a moderate decrease in body weight gain in males. The administration of carbidopa-levodopa at dose levels of 10-20, 10-50, or 10-100 mg/kg/day did not adversely affect the fertility of male or female rats, their reproductive performance, or the growth and survival of the young. Pregnancy Pregnancy Category C: There are no adequate and well-controlled studies with LODOSYN in pregnant women. It has been reported from individual cases that levodopa crosses the human placental barrier, enters the fetus, and is metabolized. Carbidopa concentrations in fetal tissue appeared to be minimal. LODOSYN should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus. Carbidopa, at doses as high as 120 mg/kg/day, was without teratogenic effects in the mouse or rabbit. In the rabbit, but not in the mouse, carbidopa-levodopa produced visceral anomalies, similar to those seen with levodopa alone, at approximately 7 times the maximum recommended human dose. The teratogenic effect of levodopa in rabbits was unchanged by the concomitant administration of carbidopa. Nursing Mothers It is not known whether carbidopa is excreted in human milk. Because many drugs are excreted in human milk, and because of their potential for serious adverse reactions in nursing infants, a decision should be made whether to discontinue nursing or to discontinue the drug, taking into account the importance of the drug to the nursing woman. Pediatric Use Safety and effectiveness in pediatric patients have not been established, and use of the drug in patients below the age of 18 is not recommended. Reference ID: 3458203 Geriatric Use Clinical studies of LODOSYN did not include sufficient numbers of subjects aged 65 and over to determine whether they respond differently from younger subjects. Other clinical experience has not identified differences in responses between the elderly and younger patients. In general, dose selection for an elderly patient should be cautious, usually starting at the low end of the dosing range, reflecting the greater frequency of decreased hepatic, renal, or cardiac function, and concomitant disease and other drug therapy. ADVERSE REACTIONS Carbidopa has not been demonstrated to have any overt pharmacodynamic actions in the recommended doses. The only adverse reactions that have been observed have been with concomitant use of carbidopa with other drugs such as levodopa, and with carbidopa­ levodopa combination products. When LODOSYN is administered concomitantly with levodopa or carbidopa-levodopa combination products, the most common adverse reactions have included dyskinesias such as choreiform, dystonic, and other involuntary movements, and nausea. Other adverse reactions reported with LODOSYN when administered concomitantly with levodopa alone or carbidopa-levodopa combination products were psychotic episodes including delusions, hallucinations, and paranoid ideation, depression with or without development of suicidal tendencies, and dementia. Convulsions also have occurred; however, a causal relationship with concomitant use of LODOSYN and levodopa has not been established. The following other adverse reactions have been reported with levodopa and carbidopa­ levodopa combination products. These same adverse reactions may also occur when LODOSYN is administered with these products. Body as a Whole: abdominal pain and distress, asthenia, chest pain, fatigue. Cardiovascular: cardiac irregularities, hypertension, myocardial infarction, hypotension including orthostatic hypotension, palpitation, phlebitis, syncope. Gastrointestinal: anorexia, bruxism, burning sensation of the tongue, constipation, dark saliva, development of duodenal ulcer, diarrhea, dry mouth, dyspepsia, dysphagia, flatulence, gastrointestinal bleeding, gastrointestinal pain, heartburn, hiccups, sialorrhea, taste alterations, vomiting. Reference ID: 3458203 Hematologic: hemolytic and non-hemolytic anemia, leukopenia, thrombocytopenia, agranulocytosis. Hypersensitivity: angioedema, urticaria, pruritus, Henoch-Schonlein purpura, bullous lesions (including pemphigus-like reactions). Metabolic: edema, weight gain, weight loss. Musculoskeletal: back pain, leg pain, muscle cramps, shoulder pain. Nervous System/Psychiatric: Psychotic episodes including delusions, hallucinations and paranoid ideation, neuroleptic malignant syndrome (NMS, see WARNINGS), bradykinetic episodes (“on-off” phenomenon), confusion, agitation, dizziness, somnolence, dream abnormalities including nightmares, insomnia, paresthesia, headache, depression with or without development of suicidal tendencies, dementia, pathological gambling, increased libido including hypersexuality, impulse control symptoms. Convulsions also have occurred; however, a causal relationship with LODOSYN and levodopa, has not been established. Respiratory: upper respiratory infection, dyspnea, pharyngeal pain, cough. Skin: flushing, increased sweating, malignant melanoma (see also CONTRAINDICATIONS), rash, alopecia, dark sweat. Special Senses: oculogyric crises, diplopia, blurred vision, dilated pupils. Urogenital: dark urine, priapism, urinary frequency, urinary incontinence, urinary retention, urinary tract infection. Laboratory Tests: abnormalities in alkaline phosphatase, SGOT (AST), SGPT (ALT), lactic dehydrogenase, bilirubin, blood urea nitrogen (BUN), Coombs test; elevated serum glucose; decreased hemoglobin and hematocrit; decreased white blood cell count and serum potassium; increased serum creatinine and uric acid; white blood cells, bacteria and blood in the urine; protein and glucose in the urine. Miscellaneous: bizarre breathing patterns, faintness, hoarseness, hot flashes, malaise, neuroleptic malignant syndrome, sense of stimulation. OVERDOSAGE No reports of overdose with LODOSYN have been received. Management of overdosage with carbidopa is the same as that with levodopa or carbidopa-levodopa preparations. Reference ID: 3458203 In the event of overdosage, general supportive measures should be employed, along with immediate gastric lavage. Intravenous fluids should be administered judiciously, and an adequate airway maintained. Electrocardiographic monitoring should be instituted and the patient carefully observed for the development of arrhythmias; if required, appropriate antiarrhythmic therapy should be given. The possibility that the patient may have taken other drugs as well as LODOSYN should be taken into consideration. To date, no experience has been reported with dialysis; hence, its value in overdosage is not known. Pyridoxine is not effective in reversing the actions of LODOSYN. Based on studies in which high doses of levodopa and/or carbidopa were administered, a significant proportion of rats and mice given single oral doses of levodopa of approximately 1500-2000 mg/kg are expected to die. A significant proportion of infant rats of both sexes are expected to die at a dose of 800 mg/kg. A significant proportion of rats are expected to die after treatment with similar doses of carbidopa. The addition of carbidopa in a 1:10 ratio with levodopa increases the dose at which a significant proportion of mice are expected to die to 3360 mg/kg. DOSAGE AND ADMINISTRATION Whether given with carbidopa-levodopa or with levodopa, the optimal daily dose of LODOSYN must be determined by careful titration. Most patients respond to a 1:10 proportion of carbidopa and levodopa, provided the daily dosage of carbidopa is 70 mg or more a day. The maximum daily dosage of carbidopa should not exceed 200 mg, since clinical experience with larger dosages is limited. If the patient is taking carbidopa-levodopa, the amount of carbidopa in carbidopa-levodopa should be considered when calculating the total amount of LODOSYN to be administered each day. Patients Receiving Carbidopa-Levodopa Who Require Additional Carbidopa Some patients taking carbidopa-levodopa may not have adequate reduction in nausea and vomiting when the dosage of carbidopa is less than 70 mg a day, and the dosage of levodopa is less than 700 mg a day. When these patients are taking carbidopa-levodopa, 25 mg of LODOSYN may be given with the first dose of carbidopa-levodopa each day. Additional doses of 12.5 mg or 25 mg may be given during the day with each dose of carbidopa­ levodopa. LODOSYN may be given with any dose carbidopa-levodopa as required for optimum therapeutic response. The maximum daily dosage of carbidopa, given as LODOSYN and as carbidopa- levodopa), should not exceed 200 mg. Patients Requiring Individual Titration of Carbidopa and Reference ID: 3458203 Levodopa Dosage Although carbidopa-levodopa is the most frequently used of carbidopa and levodopa administration, there may be an occasional patient who requires individually titrated doses of these two drugs. In these patients, LODOSYN (carbidopa) should be initiated at a dosage of 25 mg three or four times a day. The two drugs should be given at the same time, starting with no more than one-fifth (20%) to one-fourth (25%) of the previous or recommended daily dosage of levodopa when given without LODOSYN (Carbidopa). In patients already receiving levodopa therapy, at least twelve hours should elapse between the last dose of levodopa and initiation of therapy with LODOSYN (Carbidopa) and levodopa. A convenient way to initiate therapy in these patients is in the morning following a night when the patient has not taken levodopa for at least twelve hours. Health care providers who prescribe separate doses of LODOSYN and levodopa should be thoroughly familiar with the directions for use of each drug. Dosage Adjustment Dosage of LODOSYN may be adjusted by adding or omitting one-half or one tablet a day. Because both therapeutic and adverse responses occur more rapidly with combined therapy than when only levodopa is given, patients should be monitored closely during the dose adjustment period. Specifically, involuntary movements will occur more rapidly when LODOSYN and levodopa are given concomitantly than when levodopa is given without LODOSYN. The occurrence of involuntary movements may require dosage reduction. Blepharospasm may be a useful early sign of excess dosage in some patients. Current evidence indicates other standard antiparkinsonian drugs may be continued while carbidopa and levodopa are being administered. However, the dosage of such other standard antiparkinsonian drugs may require adjustment. Interruption of Therapy Sporadic cases of hyperpyrexia and confusion have been associated with dose reductions and withdrawal of carbidopa-Levodopa) or carbidopa-levodopa Extended Release. Patients should be observed carefully if abrupt reduction or discontinuation of carbidopa-levodopa or carbidopa-levodopa Extended-Release is required, especially if the patient is receiving neuroleptics. (See WARNINGS.) If general anesthesia is required, therapy may be continued as long as the patient is Reference ID: 3458203 permitted to take fluids and medication by mouth. When therapy is interrupted temporarily, the patient should be observed for symptoms resembling NMS, and the usual daily dosage may be resumed as soon as the patient is able to take medication orally.

LODOSYN ® (CARBIDOPA) TABLETS When LODOSYN (Carbidopa) is to be given to carbidopa-naive patients who are being treated with levodopa, the two drugs should be given at the same time, starting with no more than 20 to 25% of the previous daily dosage of levodopa when given without LODOSYN (Carbidopa). At least twelve hours should elapse between the last dose of levodopa and initiation of therapy with LODOSYN (Carbidopa) and levodopa. See the WARNINGS and DOSAGE AND ADMINISTRATION sections before initiating therapy. DESCRIPTION Carbidopa, an inhibitor of aromatic amino acid decarboxylation, is a white, crystalline compound, slightly soluble in water, with a molecular weight of 244.3. It is designated chemically as (–)-L-α-hydrazino-α-methyl-β-(3,4-dihydroxybenzene) propanoic acid monohydrate. Its empirical formula is C10H14N2O4•H2O and its structural formula is: structural formula LODOSYN (Carbidopa) tablets contain 25 mg of carbidopa. Inactive ingredients are cellulose,FD&C Yellow 6, magnesium stearate and starch. Tablet content is expressed in terms of anhydrous carbidopa which has a molecular weight of 226.3. CLINICAL PHARMACOLOGY Parkinson’s disease is a progressive, neurodegenerative disorder of the extrapyramidal nervous system affecting the mobility and control of the skeletal muscular system. Its characteristic features include resting tremor, rigidity, and bradykinetic movements. Symptomatic treatments, such as levodopa therapies, may permit the patient better mobility. Reference ID: 3458203 Mechanism of Action Current evidence indicates that symptoms of Parkinson’s disease are related to depletion of dopamine in the corpus striatum. Administration of dopamine is ineffective in the treatment of Parkinson’s disease apparently because it does not cross the blood-brain barrier. However, levodopa, the metabolic precursor of dopamine, does cross the blood- brain barrier, and presumably is converted to dopamine in the brain. This is thought to be the mechanism whereby levodopa relieves symptoms of Parkinson’s disease. Pharmacodynamics When levodopa is administered orally it is rapidly decarboxylated to dopamine in extracerebral tissues so that only a small portion of a given dose is transported unchanged to the central nervous system. For this reason, large doses of levodopa are required for adequate therapeutic effect and these may often be accompanied by nausea and other adverse reactions, some of which are attributable to dopamine formed in extracerebral tissues. The incidence of levodopa-induced nausea and vomiting is less when LODOSYN is used with levodopa than when levodopa is used without LODOSYN. In many patients, this reduction in nausea and vomiting will permit more rapid dosage titration. Carbidopa inhibits decarboxylation of peripheral levodopa. Carbidopa has not been demonstrated to have any overt pharmacodynamic actions in the recommended doses. It does not appear to cross the blood-brain barrier readily and does not affect the metabolism of levodopa within the central nervous system at doses of carbidopa that are recommended for maximum effective inhibition of peripheral decarboxylation of levodopa. Since its decarboxylase-inhibiting activity is limited primarily to extracerebral tissues, administration of carbidopa with levodopa makes more levodopa available for transport to the brain. However, since levodopa and carbidopa compete with certain amino acids for transport across the gut wall, the absorption of levodopa and carbidopa may be impaired in some patients on a high protein diet. Pharmacokinetics Carbidopa reduces the amount of levodopa required to produce a given response by about 75% and, when administered with levodopa, increases both plasma levels and the plasma half-life of levodopa, and decreases plasma and urinary dopamine and homovanillic acid. In clinical pharmacologic studies, simultaneous administration of separate tablets of Reference ID: 3458203 carbidopa and levodopa produced greater urinary excretion of levodopa in proportion to the excretion of dopamine when compared to the two drugs administered at separate times. Supplemental pyridoxine (vitamin B6) can be given to patients when they are receiving LODOSYN and levodopa concomitantly or the fixed combination carbidopa-levodopa or carbidopa-levodopa extended release. Previous reports in the medical literature cautioned that high doses of vitamin B6 should not be taken by patients on levodopa therapy alone because exogenously administered pyridoxine would enhance the metabolism of levodopa to dopamine. The introduction of carbidopa to levodopa therapy, which inhibits the peripheral decarboxylation of levodopa to dopamine, counteracts the metabolic-enhancing effect of pyridoxine. Carbidopa is combined with levodopa in carbidopa-levodopa and carbidopa-levodopa extended release tablets. INDICATIONS AND USAGE LODOSYN is indicated for use with carbidopa-levodopa or with levodopa in the treatment of the symptoms of idiopathic Parkinson’s disease (paralysis agitans), postencephalitic parkinsonism, and symptomatic parkinsonism, which may follow injury to the nervous system by carbon monoxide intoxication and/or manganese intoxication. LODOSYN is for use with carbidopa-levodopa in patients for whom the dosage of carbidopa-levodopa provides less than adequate daily dosage (usually 70 mg daily) of carbidopa. LODOSYN is for use with levodopa in the occasional patient whose dosage requirement of carbidopa and levodopa necessitates separate titration of each medication. LODOSYN is used with carbidopa-levodopa or with levodopa to permit the administration of lower doses of levodopa with reduced nausea and vomiting, more rapid dosage titration, and with a somewhat smoother response. However, patients with markedly irregular (“on-off”) responses to levodopa have not been shown to benefit from the addition of carbidopa. Since carbidopa prevents the reversal of levodopa effects caused by pyridoxine, supplemental pyridoxine (vitamin B6), can be given to patients when they are receiving carbidopa and levodopa concomitantly or as carbidopa-levodopa. Although the administration of LODOSYN permits control of parkinsonism and Parkinson’s disease with much lower doses of levodopa, there is no conclusive evidence at present that Reference ID: 3458203 this is beneficial other than in reducing nausea and vomiting, permitting more rapid titration, and providing a somewhat smoother response to levodopa. Certain patients who responded poorly to levodopa alone have improved when carbidopa and levodopa were given concurrently. This was most likely due to decreased peripheral decarboxylation of levodopa rather than to a primary effect of carbidopa on the peripheral nervous system. Carbidopa has not been shown to enhance the intrinsic efficacy of levodopa. In deciding whether to give LODOSYN with carbidopa-levodopa or with levodopa to patients who have nausea and/or vomiting, the physician should be aware that, while many patients may be expected to improve, some may not. Since one cannot predict which patients are likely to improve, this can only be determined by a trial of therapy. It should be further noted that in controlled trials comparing carbidopa and levodopa with levodopa alone, about half the patients with nausea and/or vomiting on levodopa alone improved spontaneously despite being retained on the same dose of levodopa during the controlled portion of the trial. CONTRAINDICATIONS LODOSYN is contraindicated in patients with known hypersensitivity to any component of this drug. Nonselective monoamine oxidase (MAO) inhibitors are contraindicated for use with levodopa or carbidopa-levodopa combination products with or without LODOSYN. These inhibitors must be discontinued at least two weeks prior to initiating therapy with levodopa. Carbidopa-levodopa or levodopa may be administered concomitantly with the manufacturer’s recommended dose of an MAO inhibitor with selectivity for MAO type B (e.g., selegiline HCl) (see PRECAUTIONS, Drug Interactions). Levodopa or carbidopa-levodopa products, with or without LODOSYN, are contra- indicated in patients with narrow-angle glaucoma. WARNINGS LODOSYN (Carbidopa) has no antiparkinsonian effect when given alone. It is indicated for use with carbidopa-levodopa or levodopa. LODOSYN (Carbidopa) does not decrease adverse reactions due to central effects of levodopa. When LODOSYN (Carbidopa) is to be given to carbidopa-naive patients who are being treated with levodopa alone, the two drugs should be given at the same time. Reference ID: 3458203 At least twelve hours should elapse between the last dose of levodopa and initiation of therapy with LODOSYN (Carbidopa) and levodopa in combination. Start with no more than one-fifth (20%) to one-fourth (25%) of the previous daily dosage of levodopa when given without LODOSYN (Carbidopa). See the DOSAGE AND ADMINISTRATION section before initiating therapy. The addition of LODOSYN with levodopa or carbidopa-levodopa reduces the peripheral effects (nausea, vomiting) due to decarboxylation of levodopa; however, LODOSYN does not decrease the adverse reactions due to the central effects of levodopa. Because LODOSYN permits more levodopa to reach the brain and more dopamine to be formed, certain adverse central nervous system (CNS) effects, e.g., dyskinesias (involuntary movements), may occur at lower dosages and sooner with levodopa in combination with LODOSYN than with levodopa alone. Falling Asleep During Activities of Daily Living and Somnolence Patients taking carbidopa-levodopa products alone or with other dopaminergic drugs have reported suddenly falling asleep without prior warning of sleepiness while engaged in activities of daily living (includes operation of motor vehicles). Some of these episodes resulted in automobile accidents. Although many of these patients reported somnolence while on dopaminergic medications, some did perceive that they had no warning signs, such as excessive drowsiness, and believed that they were alert immediately prior to the event. Some patients reported these events one year after the initiation of treatment. Falling asleep while engaged in activities of daily living usually occurs in patients experiencing pre-existing somnolence, although some patients may not give such a history. For this reason, prescribers should continually reassess patients for drowsiness or sleepiness especially since some of the events occur after the start of treatment. Prescribers should be aware that patients may not acknowledge drowsiness or sleepiness until directly questioned about drowsiness or sleepiness during specific activities. Patients who have already experienced somnolence or an episode of sudden sleep onset should not participate in these activities during treatment with LODOSYN when taking it with other carbidopa-levodopa products. Reference ID: 3458203 Before initiating treatment with LODOSYN, advise patients about the potential to develop drowsiness and ask specifically about factors that may increase the risk for somnolence with LODOSYN such as the use of concomitant sedating medications and the presence of sleep disorders. Consider discontinuing LODOSYN in patients who report significant daytime sleepiness or episodes of falling asleep during activities that require active participation (e.g., conversations, eating, etc.). If treatment with LODOSYN continues, patients should be advised not to drive and to avoid other potentially dangerous activities that might result in harm if the patients become somnolent. There is insufficient information to establish that dose reduction will eliminate episodes of falling asleep while engaged in activities of daily living. Hyperpyrexia and Confusion: Sporadic cases of a symptom complex resembling neuroleptic malignant syndrome (NMS) have been reported in association with dose reductions or withdrawal of certain antiparkinsonian agents such as levodopa, carbidopa-levodopa, or carbidopa-levodopa extended-release. Therefore, patients should be observed carefully when the dosage of levodopa or carbidopa­ levodopa is reduced abruptly or discontinued, especially if the patient is receiving neuroleptics. NMS is an uncommon but life-threatening syndrome characterized by fever or hyperthermia. Neurological findings, including muscle rigidity, involuntary movements, altered consciousness, mental status changes; other disturbances, such as autonomic dysfunction, tachycardia, tachypnea, sweating, hyper- or hypotension; laboratory findings, such as creatine phosphokinase elevation, leukocytosis, myoglobinuria, and increased serum myoglobin, have been reported. The early diagnosis of this condition is important for the appropriate management of these patients. Considering NMS as a possible diagnosis and ruling out other acute illnesses (e.g., pneumonia, systemic infection, etc.) is essential. This may be especially complex if the clinical presentation includes both serious medical illness and untreated or inadequately treated extrapyramidal signs and symptoms (EPS). Other important considerations in the differential Reference ID: 3458203 diagnosis include central anticholinergic toxicity, heat stroke, drug fever, and primary central nervous system (CNS) pathology. The management of NMS should include: 1) intensive symptomatic treatment and medical monitoring and 2) treatment of any concomitant serious medical problems for which specific treatments are available. Dopamine agonists, such as bromocriptine, and muscle relaxants, such as dantrolene, are often used in the treatment of NMS; however, their effectiveness has not been demonstrated in controlled studies. PRECAUTIONS General As with levodopa alone, periodic evaluations of hepatic, hematopoietic, cardiovascular, and renal function are recommended during extended concomitant therapy with LODOSYN and levodopa, or with LODOSYN and carbidopa-levodopa or any combination of these drugs. Impulse Control/Compulsive Behaviors Postmarketing reports suggest that patients treated with anti-Parkinson medications can experience intense urges to gamble, increased sexual urges, intense urges to spend money uncontrollably, binge eating, and other intense urges. Patients may be unable to control these urges while taking one or more of the medications that are used for the treatment of Parkinson’s disease and that increase central dopaminergic tone, including Lodosyn taken with levodopa and carbidopa. In some cases, although not all, these urges were reported to have stopped when the dose of anti-Parkinson medications was reduced or discontinued. Because patients may not recognize these behaviors as abnormal it is important for prescribers to specifically ask patients or their caregivers about the development of new or increased gambling urges, sexual urges, uncontrolled spending or other urges while being treated with Lodosyn. Physicians should consider dose reduction or stopping Lodosyn or levodopa if a patient develops such urges while taking Lodosyn with carbidopa/levodopa. Hallucinations/Psychotic-Like Behavior Reference ID: 3458203 Hallucinations and psychotic like behavior have been reported with dopaminergic medications. In general, hallucinations present shortly after the initiation of therapy and may be responsive to dose reduction in levodopa. Hallucinations may be accompanied by confusion and to a lesser extent sleep disorder (insomnia) and excessive dreaming. LODOSYN when taken with carbidopa-levodopa may have similar effects on thinking and behavior. This abnormal thinking and behavior may present with one or more symptoms, including paranoid ideation, delusions, hallucinations, confusion, psychotic-like behavior, disorientation, aggressive behavior, agitation, and delirium. Ordinarily, patients with a major psychotic disorder should not be treated with LODOSYN and carbidopa-levodopa, because of the risk of exacerbating psychosis. In addition, certain medications used to treat psychosis may exacerbate the symptoms of Parkinson’s disease and may decrease the effectiveness of LODOSYN. Dyskinesia LODOSYN (Carbidopa) may potentiate the dopaminergic side effects of levodopa and may cause or exacerbate preexisting dyskinesia. Depression Patients treated with LODOSYN and carbidopa-levodopa should be observed carefully for the development of depression with concomitant suicidal tendencies. Melanoma Epidemiological studies have shown that patients with Parkinson’s disease have a higher risk (2­ to approximately 6-fold higher) of developing melanoma than the general population. Whether the observed increased risk was due to Parkinson’s disease or other factors, such as drugs used to treat Parkinson’s disease, is unclear. For the reasons stated above, patients and providers are advised to monitor for melanomas frequently and on a regular basis when using LODOSYN tablets for Parkinson’s disease. Reference ID: 3458203 Ideally, periodic skin examinations should be performed by appropriately qualified individuals (e.g., dermatologists). Information for Patients It is important that LODOSYN with levodopa be taken at regular intervals according to the schedule outlined by the health care provider. Caution patients not to change the prescribed dosage regimen and not to add any additional antiparkinson medications, including other carbidopa-levodopa preparations without first consulting a physician. Advise patients that sometimes a ‘wearing-off’ effect may occur at the end of the dosing interval. Tell patients to notify the prescriber if such response poses a problem to lifestyle. Patients should be advised that occasionally dark color (red, brown, or black) may appear in saliva, urine, or sweat after ingestion of LODOSYN and levodopa. Although the color appears to be clinically insignificant, garments may become discolored. The patient should be advised that a change in diet to foods that are high in protein may delay the absorption of levodopa and may reduce the amount taken up in the circulation. Excessive acidity also delays stomach emptying thus delaying the absorption of levodopa. Iron salts (such as in multivitamin tablets) may also reduce the amount of levodopa available in the body. The above factors may reduce the clinical effectiveness of the LODOSYN and levodopa therapy. Alert patients to the possibility of sudden onset of sleep during daily activities, in some cases without awareness or warning signs, when they are taking dopaminergic agents, including levodopa. Advise patients to exercise caution while driving or operating machinery and that if they have experience somnolence and/or sudden sleep onset, they must refrain from these activities. (See WARNINGS, Falling Asleep During Activities of Daily Living and Somnolence General.) There have been reports of patients experiencing intense urges to gamble, increased sexual urges, and other intense urges, and the inability to control these urges while taking one or more of the medications that increase central dopaminergic tone and that are generally used for the treatment Reference ID: 3458203 of Parkinson’s disease, including LODOSYN and levodopa. Although it is not proven that the medications caused these events, these urges were reported to have stopped in some cases when the dose was reduced or the medication was stopped. Prescribers should ask patients about the development of new or increased gambling urges, sexual urges, or other intense urges while taking LODOSYN and levodopa. Physicians should consider dose reduction or stopping Lodosyn and levodopa if a patient develops such urges while taking Lodosyn with carbidopa/levodopa (See PRECAUTIONS, Impulse Control/Compulsive Behaviors). Laboratory Tests Abnormalities in laboratory tests may include elevations of liver function tests such as alkaline phosphatase, SGOT (AST), SGPT (ALT), lactic dehydrogenase, and bilirubin. Abnormalities in blood urea nitrogen and positive Coombs test have also been reported. Commonly, levels of blood urea nitrogen, creatinine, and uric acid are lower during concomitant administration of carbidopa and levodopa than with levodopa alone. Levodopa and carbidopa-levodopa combination products may cause a false-positive reaction for urinary ketone bodies when a test tape is used for determination of ketonuria. This reaction will not be altered by boiling the urine specimen. False-negative tests may result with the use of glucose-oxidase methods of testing for glucosuria. Drug Interactions Caution should be exercised when the following drugs are administered concomitantly with LODOSYN (Carbidopa) given with levodopa or carbidopa-levodopa fixed dose combination products. Symptomatic postural hypotension has occurred when LODOSYN, given with levodopa or carbidopa-levodopa combination products, was added to the treatment of a patient receiving antihypertensive drugs. Therefore, when therapy with LODOSYN, given with or without levodopa or carbidopa-levodopa combination products, is started, dosage adjustment of the antihypertensive drug may be required. Reference ID: 3458203 For patients receiving monoamine oxidase inhibitors (Type A or B), see CONTRAINDICATIONS. Concomitant therapy with selegiline or rasigiline and LODOSYN and carbidopa-levodopa may be associated with severe orthostatic hypotension not attributable to carbidopa-levodopa alone (see CONTRAINDICATIONS). There have been rare reports of adverse reactions, including hypertension and dyskinesia, resulting from the concomitant use of tricyclic antidepressants and carbidopa-levodopa preparations. Dopamine D2 receptor antagonists (e.g., phenothiazines, butyrophenones, risperidone) and isoniazid may reduce the therapeutic effects of levodopa. In addition, the beneficial effects of levodopa in Parkinson’s disease have been reported to be reversed by phenytoin and papaverine. Patients taking these drugs with LODOSYN and levodopa or carbidopa-levodopa combination products should be carefully observed for loss of therapeutic response LODOSYN and iron salts or multi vitamins containing iron salts should be co administered with caution. Iron salts c a n f or m c he l a t e s w i t h l e vod opa a nd c a r bi dopa a nd c ons e que nt l y reduce the bioavailability of carbidopa and levodopa. Although metoclopramide may increase the bioavailability of levodopa by increasing gastric emptying, metoclopramide may also adversely affect disease control by its dopamine receptor antagonistic properties. Carcinogenesis, Mutagenesis, Impairment of Fertility Carcinogenesis There were no significant differences between treated and control rats with respect to mortality or neoplasia in a 96-week study of carbidopa at oral doses of 25, 45, or 135 mg/kg/day. Combinations of carbidopa and levodopa (10-20, 10-50, 10-100 mg/kg/day) were given orally to rats for 106 weeks. No effect on mortality or incidence and type of neoplasia was seen when compared to concurrent controls. Mutagenesis Mutagenicity studies have not been performed with either carbidopa or the combination of carbidopa and levodopa. Fertility Reference ID: 3458203 Carbidopa had no effect on the mating performance, fertility, or survival of the young when administered orally to rats at doses of 30, 60, or 120 mg/kg/day. The highest dose caused a moderate decrease in body weight gain in males. The administration of carbidopa-levodopa at dose levels of 10-20, 10-50, or 10-100 mg/kg/day did not adversely affect the fertility of male or female rats, their reproductive performance, or the growth and survival of the young. Pregnancy Pregnancy Category C: There are no adequate and well-controlled studies with LODOSYN in pregnant women. It has been reported from individual cases that levodopa crosses the human placental barrier, enters the fetus, and is metabolized. Carbidopa concentrations in fetal tissue appeared to be minimal. LODOSYN should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus. Carbidopa, at doses as high as 120 mg/kg/day, was without teratogenic effects in the mouse or rabbit. In the rabbit, but not in the mouse, carbidopa-levodopa produced visceral anomalies, similar to those seen with levodopa alone, at approximately 7 times the maximum recommended human dose. The teratogenic effect of levodopa in rabbits was unchanged by the concomitant administration of carbidopa. Nursing Mothers It is not known whether carbidopa is excreted in human milk. Because many drugs are excreted in human milk, and because of their potential for serious adverse reactions in nursing infants, a decision should be made whether to discontinue nursing or to discontinue the drug, taking into account the importance of the drug to the nursing woman. Pediatric Use Safety and effectiveness in pediatric patients have not been established, and use of the drug in patients below the age of 18 is not recommended. Reference ID: 3458203 Geriatric Use Clinical studies of LODOSYN did not include sufficient numbers of subjects aged 65 and over to determine whether they respond differently from younger subjects. Other clinical experience has not identified differences in responses between the elderly and younger patients. In general, dose selection for an elderly patient should be cautious, usually starting at the low end of the dosing range, reflecting the greater frequency of decreased hepatic, renal, or cardiac function, and concomitant disease and other drug therapy. ADVERSE REACTIONS Carbidopa has not been demonstrated to have any overt pharmacodynamic actions in the recommended doses. The only adverse reactions that have been observed have been with concomitant use of carbidopa with other drugs such as levodopa, and with carbidopa­ levodopa combination products. When LODOSYN is administered concomitantly with levodopa or carbidopa-levodopa combination products, the most common adverse reactions have included dyskinesias such as choreiform, dystonic, and other involuntary movements, and nausea. Other adverse reactions reported with LODOSYN when administered concomitantly with levodopa alone or carbidopa-levodopa combination products were psychotic episodes including delusions, hallucinations, and paranoid ideation, depression with or without development of suicidal tendencies, and dementia. Convulsions also have occurred; however, a causal relationship with concomitant use of LODOSYN and levodopa has not been established. The following other adverse reactions have been reported with levodopa and carbidopa­ levodopa combination products. These same adverse reactions may also occur when LODOSYN is administered with these products. Body as a Whole: abdominal pain and distress, asthenia, chest pain, fatigue. Cardiovascular: cardiac irregularities, hypertension, myocardial infarction, hypotension including orthostatic hypotension, palpitation, phlebitis, syncope. Gastrointestinal: anorexia, bruxism, burning sensation of the tongue, constipation, dark saliva, development of duodenal ulcer, diarrhea, dry mouth, dyspepsia, dysphagia, flatulence, gastrointestinal bleeding, gastrointestinal pain, heartburn, hiccups, sialorrhea, taste alterations, vomiting. Reference ID: 3458203 Hematologic: hemolytic and non-hemolytic anemia, leukopenia, thrombocytopenia, agranulocytosis. Hypersensitivity: angioedema, urticaria, pruritus, Henoch-Schonlein purpura, bullous lesions (including pemphigus-like reactions). Metabolic: edema, weight gain, weight loss. Musculoskeletal: back pain, leg pain, muscle cramps, shoulder pain. Nervous System/Psychiatric: Psychotic episodes including delusions, hallucinations and paranoid ideation, neuroleptic malignant syndrome (NMS, see WARNINGS), bradykinetic episodes (“on-off” phenomenon), confusion, agitation, dizziness, somnolence, dream abnormalities including nightmares, insomnia, paresthesia, headache, depression with or without development of suicidal tendencies, dementia, pathological gambling, increased libido including hypersexuality, impulse control symptoms. Convulsions also have occurred; however, a causal relationship with LODOSYN and levodopa, has not been established. Respiratory: upper respiratory infection, dyspnea, pharyngeal pain, cough. Skin: flushing, increased sweating, malignant melanoma (see also CONTRAINDICATIONS), rash, alopecia, dark sweat. Special Senses: oculogyric crises, diplopia, blurred vision, dilated pupils. Urogenital: dark urine, priapism, urinary frequency, urinary incontinence, urinary retention, urinary tract infection. Laboratory Tests: abnormalities in alkaline phosphatase, SGOT (AST), SGPT (ALT), lactic dehydrogenase, bilirubin, blood urea nitrogen (BUN), Coombs test; elevated serum glucose; decreased hemoglobin and hematocrit; decreased white blood cell count and serum potassium; increased serum creatinine and uric acid; white blood cells, bacteria and blood in the urine; protein and glucose in the urine. Miscellaneous: bizarre breathing patterns, faintness, hoarseness, hot flashes, malaise, neuroleptic malignant syndrome, sense of stimulation. OVERDOSAGE No reports of overdose with LODOSYN have been received. Management of overdosage with carbidopa is the same as that with levodopa or carbidopa-levodopa preparations. Reference ID: 3458203 In the event of overdosage, general supportive measures should be employed, along with immediate gastric lavage. Intravenous fluids should be administered judiciously, and an adequate airway maintained. Electrocardiographic monitoring should be instituted and the patient carefully observed for the development of arrhythmias; if required, appropriate antiarrhythmic therapy should be given. The possibility that the patient may have taken other drugs as well as LODOSYN should be taken into consideration. To date, no experience has been reported with dialysis; hence, its value in overdosage is not known. Pyridoxine is not effective in reversing the actions of LODOSYN. Based on studies in which high doses of levodopa and/or carbidopa were administered, a significant proportion of rats and mice given single oral doses of levodopa of approximately 1500-2000 mg/kg are expected to die. A significant proportion of infant rats of both sexes are expected to die at a dose of 800 mg/kg. A significant proportion of rats are expected to die after treatment with similar doses of carbidopa. The addition of carbidopa in a 1:10 ratio with levodopa increases the dose at which a significant proportion of mice are expected to die to 3360 mg/kg. DOSAGE AND ADMINISTRATION Whether given with carbidopa-levodopa or with levodopa, the optimal daily dose of LODOSYN must be determined by careful titration. Most patients respond to a 1:10 proportion of carbidopa and levodopa, provided the daily dosage of carbidopa is 70 mg or more a day. The maximum daily dosage of carbidopa should not exceed 200 mg, since clinical experience with larger dosages is limited. If the patient is taking carbidopa-levodopa, the amount of carbidopa in carbidopa-levodopa should be considered when calculating the total amount of LODOSYN to be administered each day. Patients Receiving Carbidopa-Levodopa Who Require Additional Carbidopa Some patients taking carbidopa-levodopa may not have adequate reduction in nausea and vomiting when the dosage of carbidopa is less than 70 mg a day, and the dosage of levodopa is less than 700 mg a day. When these patients are taking carbidopa-levodopa, 25 mg of LODOSYN may be given with the first dose of carbidopa-levodopa each day. Additional doses of 12.5 mg or 25 mg may be given during the day with each dose of carbidopa­ levodopa. LODOSYN may be given with any dose carbidopa-levodopa as required for optimum therapeutic response. The maximum daily dosage of carbidopa, given as LODOSYN and as carbidopa- levodopa), should not exceed 200 mg. Patients Requiring Individual Titration of Carbidopa and Reference ID: 3458203 Levodopa Dosage Although carbidopa-levodopa is the most frequently used of carbidopa and levodopa administration, there may be an occasional patient who requires individually titrated doses of these two drugs. In these patients, LODOSYN (carbidopa) should be initiated at a dosage of 25 mg three or four times a day. The two drugs should be given at the same time, starting with no more than one-fifth (20%) to one-fourth (25%) of the previous or recommended daily dosage of levodopa when given without LODOSYN (Carbidopa). In patients already receiving levodopa therapy, at least twelve hours should elapse between the last dose of levodopa and initiation of therapy with LODOSYN (Carbidopa) and levodopa. A convenient way to initiate therapy in these patients is in the morning following a night when the patient has not taken levodopa for at least twelve hours. Health care providers who prescribe separate doses of LODOSYN and levodopa should be thoroughly familiar with the directions for use of each drug. Dosage Adjustment Dosage of LODOSYN may be adjusted by adding or omitting one-half or one tablet a day. Because both therapeutic and adverse responses occur more rapidly with combined therapy than when only levodopa is given, patients should be monitored closely during the dose adjustment period. Specifically, involuntary movements will occur more rapidly when LODOSYN and levodopa are given concomitantly than when levodopa is given without LODOSYN. The occurrence of involuntary movements may require dosage reduction. Blepharospasm may be a useful early sign of excess dosage in some patients. Current evidence indicates other standard antiparkinsonian drugs may be continued while carbidopa and levodopa are being administered. However, the dosage of such other standard antiparkinsonian drugs may require adjustment. Interruption of Therapy Sporadic cases of hyperpyrexia and confusion have been associated with dose reductions and withdrawal of carbidopa-Levodopa) or carbidopa-levodopa Extended Release. Patients should be observed carefully if abrupt reduction or discontinuation of carbidopa-levodopa or carbidopa-levodopa Extended-Release is required, especially if the patient is receiving neuroleptics. (See WARNINGS.) If general anesthesia is required, therapy may be continued as long as the patient is Reference ID: 3458203 permitted to take fluids and medication by mouth. When therapy is interrupted temporarily, the patient should be observed for symptoms resembling NMS, and the usual daily dosage may be resumed as soon as the patient is able to take medication orally.

LODOSYN ® (CARBIDOPA) TABLETS When LODOSYN (Carbidopa) is to be given to carbidopa-naive patients who are being treated with levodopa, the two drugs should be given at the same time, starting with no more than 20 to 25% of the previous daily dosage of levodopa when given without LODOSYN (Carbidopa). At least twelve hours should elapse between the last dose of levodopa and initiation of therapy with LODOSYN (Carbidopa) and levodopa. See the WARNINGS and DOSAGE AND ADMINISTRATION sections before initiating therapy. DESCRIPTION Carbidopa, an inhibitor of aromatic amino acid decarboxylation, is a white, crystalline compound, slightly soluble in water, with a molecular weight of 244.3. It is designated chemically as (–)-L-α-hydrazino-α-methyl-β-(3,4-dihydroxybenzene) propanoic acid monohydrate. Its empirical formula is C10H14N2O4•H2O and its structural formula is: structural formula LODOSYN (Carbidopa) tablets contain 25 mg of carbidopa. Inactive ingredients are cellulose,FD&C Yellow 6, magnesium stearate and starch. Tablet content is expressed in terms of anhydrous carbidopa which has a molecular weight of 226.3. CLINICAL PHARMACOLOGY Parkinson’s disease is a progressive, neurodegenerative disorder of the extrapyramidal nervous system affecting the mobility and control of the skeletal muscular system. Its characteristic features include resting tremor, rigidity, and bradykinetic movements. Symptomatic treatments, such as levodopa therapies, may permit the patient better mobility. Reference ID: 3458203 Mechanism of Action Current evidence indicates that symptoms of Parkinson’s disease are related to depletion of dopamine in the corpus striatum. Administration of dopamine is ineffective in the treatment of Parkinson’s disease apparently because it does not cross the blood-brain barrier. However, levodopa, the metabolic precursor of dopamine, does cross the blood- brain barrier, and presumably is converted to dopamine in the brain. This is thought to be the mechanism whereby levodopa relieves symptoms of Parkinson’s disease. Pharmacodynamics When levodopa is administered orally it is rapidly decarboxylated to dopamine in extracerebral tissues so that only a small portion of a given dose is transported unchanged to the central nervous system. For this reason, large doses of levodopa are required for adequate therapeutic effect and these may often be accompanied by nausea and other adverse reactions, some of which are attributable to dopamine formed in extracerebral tissues. The incidence of levodopa-induced nausea and vomiting is less when LODOSYN is used with levodopa than when levodopa is used without LODOSYN. In many patients, this reduction in nausea and vomiting will permit more rapid dosage titration. Carbidopa inhibits decarboxylation of peripheral levodopa. Carbidopa has not been demonstrated to have any overt pharmacodynamic actions in the recommended doses. It does not appear to cross the blood-brain barrier readily and does not affect the metabolism of levodopa within the central nervous system at doses of carbidopa that are recommended for maximum effective inhibition of peripheral decarboxylation of levodopa. Since its decarboxylase-inhibiting activity is limited primarily to extracerebral tissues, administration of carbidopa with levodopa makes more levodopa available for transport to the brain. However, since levodopa and carbidopa compete with certain amino acids for transport across the gut wall, the absorption of levodopa and carbidopa may be impaired in some patients on a high protein diet. Pharmacokinetics Carbidopa reduces the amount of levodopa required to produce a given response by about 75% and, when administered with levodopa, increases both plasma levels and the plasma half-life of levodopa, and decreases plasma and urinary dopamine and homovanillic acid. In clinical pharmacologic studies, simultaneous administration of separate tablets of Reference ID: 3458203 carbidopa and levodopa produced greater urinary excretion of levodopa in proportion to the excretion of dopamine when compared to the two drugs administered at separate times. Supplemental pyridoxine (vitamin B6) can be given to patients when they are receiving LODOSYN and levodopa concomitantly or the fixed combination carbidopa-levodopa or carbidopa-levodopa extended release. Previous reports in the medical literature cautioned that high doses of vitamin B6 should not be taken by patients on levodopa therapy alone because exogenously administered pyridoxine would enhance the metabolism of levodopa to dopamine. The introduction of carbidopa to levodopa therapy, which inhibits the peripheral decarboxylation of levodopa to dopamine, counteracts the metabolic-enhancing effect of pyridoxine. Carbidopa is combined with levodopa in carbidopa-levodopa and carbidopa-levodopa extended release tablets. INDICATIONS AND USAGE LODOSYN is indicated for use with carbidopa-levodopa or with levodopa in the treatment of the symptoms of idiopathic Parkinson’s disease (paralysis agitans), postencephalitic parkinsonism, and symptomatic parkinsonism, which may follow injury to the nervous system by carbon monoxide intoxication and/or manganese intoxication. LODOSYN is for use with carbidopa-levodopa in patients for whom the dosage of carbidopa-levodopa provides less than adequate daily dosage (usually 70 mg daily) of carbidopa. LODOSYN is for use with levodopa in the occasional patient whose dosage requirement of carbidopa and levodopa necessitates separate titration of each medication. LODOSYN is used with carbidopa-levodopa or with levodopa to permit the administration of lower doses of levodopa with reduced nausea and vomiting, more rapid dosage titration, and with a somewhat smoother response. However, patients with markedly irregular (“on-off”) responses to levodopa have not been shown to benefit from the addition of carbidopa. Since carbidopa prevents the reversal of levodopa effects caused by pyridoxine, supplemental pyridoxine (vitamin B6), can be given to patients when they are receiving carbidopa and levodopa concomitantly or as carbidopa-levodopa. Although the administration of LODOSYN permits control of parkinsonism and Parkinson’s disease with much lower doses of levodopa, there is no conclusive evidence at present that Reference ID: 3458203 this is beneficial other than in reducing nausea and vomiting, permitting more rapid titration, and providing a somewhat smoother response to levodopa. Certain patients who responded poorly to levodopa alone have improved when carbidopa and levodopa were given concurrently. This was most likely due to decreased peripheral decarboxylation of levodopa rather than to a primary effect of carbidopa on the peripheral nervous system. Carbidopa has not been shown to enhance the intrinsic efficacy of levodopa. In deciding whether to give LODOSYN with carbidopa-levodopa or with levodopa to patients who have nausea and/or vomiting, the physician should be aware that, while many patients may be expected to improve, some may not. Since one cannot predict which patients are likely to improve, this can only be determined by a trial of therapy. It should be further noted that in controlled trials comparing carbidopa and levodopa with levodopa alone, about half the patients with nausea and/or vomiting on levodopa alone improved spontaneously despite being retained on the same dose of levodopa during the controlled portion of the trial. CONTRAINDICATIONS LODOSYN is contraindicated in patients with known hypersensitivity to any component of this drug. Nonselective monoamine oxidase (MAO) inhibitors are contraindicated for use with levodopa or carbidopa-levodopa combination products with or without LODOSYN. These inhibitors must be discontinued at least two weeks prior to initiating therapy with levodopa. Carbidopa-levodopa or levodopa may be administered concomitantly with the manufacturer’s recommended dose of an MAO inhibitor with selectivity for MAO type B (e.g., selegiline HCl) (see PRECAUTIONS, Drug Interactions). Levodopa or carbidopa-levodopa products, with or without LODOSYN, are contra- indicated in patients with narrow-angle glaucoma. WARNINGS LODOSYN (Carbidopa) has no antiparkinsonian effect when given alone. It is indicated for use with carbidopa-levodopa or levodopa. LODOSYN (Carbidopa) does not decrease adverse reactions due to central effects of levodopa. When LODOSYN (Carbidopa) is to be given to carbidopa-naive patients who are being treated with levodopa alone, the two drugs should be given at the same time. Reference ID: 3458203 At least twelve hours should elapse between the last dose of levodopa and initiation of therapy with LODOSYN (Carbidopa) and levodopa in combination. Start with no more than one-fifth (20%) to one-fourth (25%) of the previous daily dosage of levodopa when given without LODOSYN (Carbidopa). See the DOSAGE AND ADMINISTRATION section before initiating therapy. The addition of LODOSYN with levodopa or carbidopa-levodopa reduces the peripheral effects (nausea, vomiting) due to decarboxylation of levodopa; however, LODOSYN does not decrease the adverse reactions due to the central effects of levodopa. Because LODOSYN permits more levodopa to reach the brain and more dopamine to be formed, certain adverse central nervous system (CNS) effects, e.g., dyskinesias (involuntary movements), may occur at lower dosages and sooner with levodopa in combination with LODOSYN than with levodopa alone. Falling Asleep During Activities of Daily Living and Somnolence Patients taking carbidopa-levodopa products alone or with other dopaminergic drugs have reported suddenly falling asleep without prior warning of sleepiness while engaged in activities of daily living (includes operation of motor vehicles). Some of these episodes resulted in automobile accidents. Although many of these patients reported somnolence while on dopaminergic medications, some did perceive that they had no warning signs, such as excessive drowsiness, and believed that they were alert immediately prior to the event. Some patients reported these events one year after the initiation of treatment. Falling asleep while engaged in activities of daily living usually occurs in patients experiencing pre-existing somnolence, although some patients may not give such a history. For this reason, prescribers should continually reassess patients for drowsiness or sleepiness especially since some of the events occur after the start of treatment. Prescribers should be aware that patients may not acknowledge drowsiness or sleepiness until directly questioned about drowsiness or sleepiness during specific activities. Patients who have already experienced somnolence or an episode of sudden sleep onset should not participate in these activities during treatment with LODOSYN when taking it with other carbidopa-levodopa products. Reference ID: 3458203 Before initiating treatment with LODOSYN, advise patients about the potential to develop drowsiness and ask specifically about factors that may increase the risk for somnolence with LODOSYN such as the use of concomitant sedating medications and the presence of sleep disorders. Consider discontinuing LODOSYN in patients who report significant daytime sleepiness or episodes of falling asleep during activities that require active participation (e.g., conversations, eating, etc.). If treatment with LODOSYN continues, patients should be advised not to drive and to avoid other potentially dangerous activities that might result in harm if the patients become somnolent. There is insufficient information to establish that dose reduction will eliminate episodes of falling asleep while engaged in activities of daily living. Hyperpyrexia and Confusion: Sporadic cases of a symptom complex resembling neuroleptic malignant syndrome (NMS) have been reported in association with dose reductions or withdrawal of certain antiparkinsonian agents such as levodopa, carbidopa-levodopa, or carbidopa-levodopa extended-release. Therefore, patients should be observed carefully when the dosage of levodopa or carbidopa­ levodopa is reduced abruptly or discontinued, especially if the patient is receiving neuroleptics. NMS is an uncommon but life-threatening syndrome characterized by fever or hyperthermia. Neurological findings, including muscle rigidity, involuntary movements, altered consciousness, mental status changes; other disturbances, such as autonomic dysfunction, tachycardia, tachypnea, sweating, hyper- or hypotension; laboratory findings, such as creatine phosphokinase elevation, leukocytosis, myoglobinuria, and increased serum myoglobin, have been reported. The early diagnosis of this condition is important for the appropriate management of these patients. Considering NMS as a possible diagnosis and ruling out other acute illnesses (e.g., pneumonia, systemic infection, etc.) is essential. This may be especially complex if the clinical presentation includes both serious medical illness and untreated or inadequately treated extrapyramidal signs and symptoms (EPS). Other important considerations in the differential Reference ID: 3458203 diagnosis include central anticholinergic toxicity, heat stroke, drug fever, and primary central nervous system (CNS) pathology. The management of NMS should include: 1) intensive symptomatic treatment and medical monitoring and 2) treatment of any concomitant serious medical problems for which specific treatments are available. Dopamine agonists, such as bromocriptine, and muscle relaxants, such as dantrolene, are often used in the treatment of NMS; however, their effectiveness has not been demonstrated in controlled studies. PRECAUTIONS General As with levodopa alone, periodic evaluations of hepatic, hematopoietic, cardiovascular, and renal function are recommended during extended concomitant therapy with LODOSYN and levodopa, or with LODOSYN and carbidopa-levodopa or any combination of these drugs. Impulse Control/Compulsive Behaviors Postmarketing reports suggest that patients treated with anti-Parkinson medications can experience intense urges to gamble, increased sexual urges, intense urges to spend money uncontrollably, binge eating, and other intense urges. Patients may be unable to control these urges while taking one or more of the medications that are used for the treatment of Parkinson’s disease and that increase central dopaminergic tone, including Lodosyn taken with levodopa and carbidopa. In some cases, although not all, these urges were reported to have stopped when the dose of anti-Parkinson medications was reduced or discontinued. Because patients may not recognize these behaviors as abnormal it is important for prescribers to specifically ask patients or their caregivers about the development of new or increased gambling urges, sexual urges, uncontrolled spending or other urges while being treated with Lodosyn. Physicians should consider dose reduction or stopping Lodosyn or levodopa if a patient develops such urges while taking Lodosyn with carbidopa/levodopa. Hallucinations/Psychotic-Like Behavior Reference ID: 3458203 Hallucinations and psychotic like behavior have been reported with dopaminergic medications. In general, hallucinations present shortly after the initiation of therapy and may be responsive to dose reduction in levodopa. Hallucinations may be accompanied by confusion and to a lesser extent sleep disorder (insomnia) and excessive dreaming. LODOSYN when taken with carbidopa-levodopa may have similar effects on thinking and behavior. This abnormal thinking and behavior may present with one or more symptoms, including paranoid ideation, delusions, hallucinations, confusion, psychotic-like behavior, disorientation, aggressive behavior, agitation, and delirium. Ordinarily, patients with a major psychotic disorder should not be treated with LODOSYN and carbidopa-levodopa, because of the risk of exacerbating psychosis. In addition, certain medications used to treat psychosis may exacerbate the symptoms of Parkinson’s disease and may decrease the effectiveness of LODOSYN. Dyskinesia LODOSYN (Carbidopa) may potentiate the dopaminergic side effects of levodopa and may cause or exacerbate preexisting dyskinesia. Depression Patients treated with LODOSYN and carbidopa-levodopa should be observed carefully for the development of depression with concomitant suicidal tendencies. Melanoma Epidemiological studies have shown that patients with Parkinson’s disease have a higher risk (2­ to approximately 6-fold higher) of developing melanoma than the general population. Whether the observed increased risk was due to Parkinson’s disease or other factors, such as drugs used to treat Parkinson’s disease, is unclear. For the reasons stated above, patients and providers are advised to monitor for melanomas frequently and on a regular basis when using LODOSYN tablets for Parkinson’s disease. Reference ID: 3458203 Ideally, periodic skin examinations should be performed by appropriately qualified individuals (e.g., dermatologists). Information for Patients It is important that LODOSYN with levodopa be taken at regular intervals according to the schedule outlined by the health care provider. Caution patients not to change the prescribed dosage regimen and not to add any additional antiparkinson medications, including other carbidopa-levodopa preparations without first consulting a physician. Advise patients that sometimes a ‘wearing-off’ effect may occur at the end of the dosing interval. Tell patients to notify the prescriber if such response poses a problem to lifestyle. Patients should be advised that occasionally dark color (red, brown, or black) may appear in saliva, urine, or sweat after ingestion of LODOSYN and levodopa. Although the color appears to be clinically insignificant, garments may become discolored. The patient should be advised that a change in diet to foods that are high in protein may delay the absorption of levodopa and may reduce the amount taken up in the circulation. Excessive acidity also delays stomach emptying thus delaying the absorption of levodopa. Iron salts (such as in multivitamin tablets) may also reduce the amount of levodopa available in the body. The above factors may reduce the clinical effectiveness of the LODOSYN and levodopa therapy. Alert patients to the possibility of sudden onset of sleep during daily activities, in some cases without awareness or warning signs, when they are taking dopaminergic agents, including levodopa. Advise patients to exercise caution while driving or operating machinery and that if they have experience somnolence and/or sudden sleep onset, they must refrain from these activities. (See WARNINGS, Falling Asleep During Activities of Daily Living and Somnolence General.) There have been reports of patients experiencing intense urges to gamble, increased sexual urges, and other intense urges, and the inability to control these urges while taking one or more of the medications that increase central dopaminergic tone and that are generally used for the treatment Reference ID: 3458203 of Parkinson’s disease, including LODOSYN and levodopa. Although it is not proven that the medications caused these events, these urges were reported to have stopped in some cases when the dose was reduced or the medication was stopped. Prescribers should ask patients about the development of new or increased gambling urges, sexual urges, or other intense urges while taking LODOSYN and levodopa. Physicians should consider dose reduction or stopping Lodosyn and levodopa if a patient develops such urges while taking Lodosyn with carbidopa/levodopa (See PRECAUTIONS, Impulse Control/Compulsive Behaviors). Laboratory Tests Abnormalities in laboratory tests may include elevations of liver function tests such as alkaline phosphatase, SGOT (AST), SGPT (ALT), lactic dehydrogenase, and bilirubin. Abnormalities in blood urea nitrogen and positive Coombs test have also been reported. Commonly, levels of blood urea nitrogen, creatinine, and uric acid are lower during concomitant administration of carbidopa and levodopa than with levodopa alone. Levodopa and carbidopa-levodopa combination products may cause a false-positive reaction for urinary ketone bodies when a test tape is used for determination of ketonuria. This reaction will not be altered by boiling the urine specimen. False-negative tests may result with the use of glucose-oxidase methods of testing for glucosuria. Drug Interactions Caution should be exercised when the following drugs are administered concomitantly with LODOSYN (Carbidopa) given with levodopa or carbidopa-levodopa fixed dose combination products. Symptomatic postural hypotension has occurred when LODOSYN, given with levodopa or carbidopa-levodopa combination products, was added to the treatment of a patient receiving antihypertensive drugs. Therefore, when therapy with LODOSYN, given with or without levodopa or carbidopa-levodopa combination products, is started, dosage adjustment of the antihypertensive drug may be required. Reference ID: 3458203 For patients receiving monoamine oxidase inhibitors (Type A or B), see CONTRAINDICATIONS. Concomitant therapy with selegiline or rasigiline and LODOSYN and carbidopa-levodopa may be associated with severe orthostatic hypotension not attributable to carbidopa-levodopa alone (see CONTRAINDICATIONS). There have been rare reports of adverse reactions, including hypertension and dyskinesia, resulting from the concomitant use of tricyclic antidepressants and carbidopa-levodopa preparations. Dopamine D2 receptor antagonists (e.g., phenothiazines, butyrophenones, risperidone) and isoniazid may reduce the therapeutic effects of levodopa. In addition, the beneficial effects of levodopa in Parkinson’s disease have been reported to be reversed by phenytoin and papaverine. Patients taking these drugs with LODOSYN and levodopa or carbidopa-levodopa combination products should be carefully observed for loss of therapeutic response LODOSYN and iron salts or multi vitamins containing iron salts should be co administered with caution. Iron salts c a n f or m c he l a t e s w i t h l e vod opa a nd c a r bi dopa a nd c ons e que nt l y reduce the bioavailability of carbidopa and levodopa. Although metoclopramide may increase the bioavailability of levodopa by increasing gastric emptying, metoclopramide may also adversely affect disease control by its dopamine receptor antagonistic properties. Carcinogenesis, Mutagenesis, Impairment of Fertility Carcinogenesis There were no significant differences between treated and control rats with respect to mortality or neoplasia in a 96-week study of carbidopa at oral doses of 25, 45, or 135 mg/kg/day. Combinations of carbidopa and levodopa (10-20, 10-50, 10-100 mg/kg/day) were given orally to rats for 106 weeks. No effect on mortality or incidence and type of neoplasia was seen when compared to concurrent controls. Mutagenesis Mutagenicity studies have not been performed with either carbidopa or the combination of carbidopa and levodopa. Fertility Reference ID: 3458203 Carbidopa had no effect on the mating performance, fertility, or survival of the young when administered orally to rats at doses of 30, 60, or 120 mg/kg/day. The highest dose caused a moderate decrease in body weight gain in males. The administration of carbidopa-levodopa at dose levels of 10-20, 10-50, or 10-100 mg/kg/day did not adversely affect the fertility of male or female rats, their reproductive performance, or the growth and survival of the young. Pregnancy Pregnancy Category C: There are no adequate and well-controlled studies with LODOSYN in pregnant women. It has been reported from individual cases that levodopa crosses the human placental barrier, enters the fetus, and is metabolized. Carbidopa concentrations in fetal tissue appeared to be minimal. LODOSYN should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus. Carbidopa, at doses as high as 120 mg/kg/day, was without teratogenic effects in the mouse or rabbit. In the rabbit, but not in the mouse, carbidopa-levodopa produced visceral anomalies, similar to those seen with levodopa alone, at approximately 7 times the maximum recommended human dose. The teratogenic effect of levodopa in rabbits was unchanged by the concomitant administration of carbidopa. Nursing Mothers It is not known whether carbidopa is excreted in human milk. Because many drugs are excreted in human milk, and because of their potential for serious adverse reactions in nursing infants, a decision should be made whether to discontinue nursing or to discontinue the drug, taking into account the importance of the drug to the nursing woman. Pediatric Use Safety and effectiveness in pediatric patients have not been established, and use of the drug in patients below the age of 18 is not recommended. Reference ID: 3458203 Geriatric Use Clinical studies of LODOSYN did not include sufficient numbers of subjects aged 65 and over to determine whether they respond differently from younger subjects. Other clinical experience has not identified differences in responses between the elderly and younger patients. In general, dose selection for an elderly patient should be cautious, usually starting at the low end of the dosing range, reflecting the greater frequency of decreased hepatic, renal, or cardiac function, and concomitant disease and other drug therapy. ADVERSE REACTIONS Carbidopa has not been demonstrated to have any overt pharmacodynamic actions in the recommended doses. The only adverse reactions that have been observed have been with concomitant use of carbidopa with other drugs such as levodopa, and with carbidopa­ levodopa combination products. When LODOSYN is administered concomitantly with levodopa or carbidopa-levodopa combination products, the most common adverse reactions have included dyskinesias such as choreiform, dystonic, and other involuntary movements, and nausea. Other adverse reactions reported with LODOSYN when administered concomitantly with levodopa alone or carbidopa-levodopa combination products were psychotic episodes including delusions, hallucinations, and paranoid ideation, depression with or without development of suicidal tendencies, and dementia. Convulsions also have occurred; however, a causal relationship with concomitant use of LODOSYN and levodopa has not been established. The following other adverse reactions have been reported with levodopa and carbidopa­ levodopa combination products. These same adverse reactions may also occur when LODOSYN is administered with these products. Body as a Whole: abdominal pain and distress, asthenia, chest pain, fatigue. Cardiovascular: cardiac irregularities, hypertension, myocardial infarction, hypotension including orthostatic hypotension, palpitation, phlebitis, syncope. Gastrointestinal: anorexia, bruxism, burning sensation of the tongue, constipation, dark saliva, development of duodenal ulcer, diarrhea, dry mouth, dyspepsia, dysphagia, flatulence, gastrointestinal bleeding, gastrointestinal pain, heartburn, hiccups, sialorrhea, taste alterations, vomiting. Reference ID: 3458203 Hematologic: hemolytic and non-hemolytic anemia, leukopenia, thrombocytopenia, agranulocytosis. Hypersensitivity: angioedema, urticaria, pruritus, Henoch-Schonlein purpura, bullous lesions (including pemphigus-like reactions). Metabolic: edema, weight gain, weight loss. Musculoskeletal: back pain, leg pain, muscle cramps, shoulder pain. Nervous System/Psychiatric: Psychotic episodes including delusions, hallucinations and paranoid ideation, neuroleptic malignant syndrome (NMS, see WARNINGS), bradykinetic episodes (“on-off” phenomenon), confusion, agitation, dizziness, somnolence, dream abnormalities including nightmares, insomnia, paresthesia, headache, depression with or without development of suicidal tendencies, dementia, pathological gambling, increased libido including hypersexuality, impulse control symptoms. Convulsions also have occurred; however, a causal relationship with LODOSYN and levodopa, has not been established. Respiratory: upper respiratory infection, dyspnea, pharyngeal pain, cough. Skin: flushing, increased sweating, malignant melanoma (see also CONTRAINDICATIONS), rash, alopecia, dark sweat. Special Senses: oculogyric crises, diplopia, blurred vision, dilated pupils. Urogenital: dark urine, priapism, urinary frequency, urinary incontinence, urinary retention, urinary tract infection. Laboratory Tests: abnormalities in alkaline phosphatase, SGOT (AST), SGPT (ALT), lactic dehydrogenase, bilirubin, blood urea nitrogen (BUN), Coombs test; elevated serum glucose; decreased hemoglobin and hematocrit; decreased white blood cell count and serum potassium; increased serum creatinine and uric acid; white blood cells, bacteria and blood in the urine; protein and glucose in the urine. Miscellaneous: bizarre breathing patterns, faintness, hoarseness, hot flashes, malaise, neuroleptic malignant syndrome, sense of stimulation. OVERDOSAGE No reports of overdose with LODOSYN have been received. Management of overdosage with carbidopa is the same as that with levodopa or carbidopa-levodopa preparations. Reference ID: 3458203 In the event of overdosage, general supportive measures should be employed, along with immediate gastric lavage. Intravenous fluids should be administered judiciously, and an adequate airway maintained. Electrocardiographic monitoring should be instituted and the patient carefully observed for the development of arrhythmias; if required, appropriate antiarrhythmic therapy should be given. The possibility that the patient may have taken other drugs as well as LODOSYN should be taken into consideration. To date, no experience has been reported with dialysis; hence, its value in overdosage is not known. Pyridoxine is not effective in reversing the actions of LODOSYN. Based on studies in which high doses of levodopa and/or carbidopa were administered, a significant proportion of rats and mice given single oral doses of levodopa of approximately 1500-2000 mg/kg are expected to die. A significant proportion of infant rats of both sexes are expected to die at a dose of 800 mg/kg. A significant proportion of rats are expected to die after treatment with similar doses of carbidopa. The addition of carbidopa in a 1:10 ratio with levodopa increases the dose at which a significant proportion of mice are expected to die to 3360 mg/kg. DOSAGE AND ADMINISTRATION Whether given with carbidopa-levodopa or with levodopa, the optimal daily dose of LODOSYN must be determined by careful titration. Most patients respond to a 1:10 proportion of carbidopa and levodopa, provided the daily dosage of carbidopa is 70 mg or more a day. The maximum daily dosage of carbidopa should not exceed 200 mg, since clinical experience with larger dosages is limited. If the patient is taking carbidopa-levodopa, the amount of carbidopa in carbidopa-levodopa should be considered when calculating the total amount of LODOSYN to be administered each day. Patients Receiving Carbidopa-Levodopa Who Require Additional Carbidopa Some patients taking carbidopa-levodopa may not have adequate reduction in nausea and vomiting when the dosage of carbidopa is less than 70 mg a day, and the dosage of levodopa is less than 700 mg a day. When these patients are taking carbidopa-levodopa, 25 mg of LODOSYN may be given with the first dose of carbidopa-levodopa each day. Additional doses of 12.5 mg or 25 mg may be given during the day with each dose of carbidopa­ levodopa. LODOSYN may be given with any dose carbidopa-levodopa as required for optimum therapeutic response. The maximum daily dosage of carbidopa, given as LODOSYN and as carbidopa- levodopa), should not exceed 200 mg. Patients Requiring Individual Titration of Carbidopa and Reference ID: 3458203 Levodopa Dosage Although carbidopa-levodopa is the most frequently used of carbidopa and levodopa administration, there may be an occasional patient who requires individually titrated doses of these two drugs. In these patients, LODOSYN (carbidopa) should be initiated at a dosage of 25 mg three or four times a day. The two drugs should be given at the same time, starting with no more than one-fifth (20%) to one-fourth (25%) of the previous or recommended daily dosage of levodopa when given without LODOSYN (Carbidopa). In patients already receiving levodopa therapy, at least twelve hours should elapse between the last dose of levodopa and initiation of therapy with LODOSYN (Carbidopa) and levodopa. A convenient way to initiate therapy in these patients is in the morning following a night when the patient has not taken levodopa for at least twelve hours. Health care providers who prescribe separate doses of LODOSYN and levodopa should be thoroughly familiar with the directions for use of each drug. Dosage Adjustment Dosage of LODOSYN may be adjusted by adding or omitting one-half or one tablet a day. Because both therapeutic and adverse responses occur more rapidly with combined therapy than when only levodopa is given, patients should be monitored closely during the dose adjustment period. Specifically, involuntary movements will occur more rapidly when LODOSYN and levodopa are given concomitantly than when levodopa is given without LODOSYN. The occurrence of involuntary movements may require dosage reduction. Blepharospasm may be a useful early sign of excess dosage in some patients. Current evidence indicates other standard antiparkinsonian drugs may be continued while carbidopa and levodopa are being administered. However, the dosage of such other standard antiparkinsonian drugs may require adjustment. Interruption of Therapy Sporadic cases of hyperpyrexia and confusion have been associated with dose reductions and withdrawal of carbidopa-Levodopa) or carbidopa-levodopa Extended Release. Patients should be observed carefully if abrupt reduction or discontinuation of carbidopa-levodopa or carbidopa-levodopa Extended-Release is required, especially if the patient is receiving neuroleptics. (See WARNINGS.) If general anesthesia is required, therapy may be continued as long as the patient is Reference ID: 3458203 permitted to take fluids and medication by mouth. When therapy is interrupted temporarily, the patient should be observed for symptoms resembling NMS, and the usual daily dosage may be resumed as soon as the patient is able to take medication orally.

REGLAN - metoclopramide tablet  Alaven Pharmaceutical LLC ---------- reglan tablets (metoclopramide tablets, USP) Rx Only WARNING TARDIVE DYSKINESIA Treatment with metoclopramide can cause tardive dyskinesia, a serious movement disorder that is often irreversible. The risk of developing tardive dyskinesia increases with duration of treatment and total cumulative dose. Metoclopramide therapy should be discontinued in patients who develop signs or symptoms of tardive dyskinesia. There is no known treatment for tardive dyskinesia. In some patients, symptoms may lessen or resolve after metoclopramide treatment is stopped. Treatment with metoclopramide for longer than 12 weeks should be avoided in all but rare cases where therapeutic benefit is thought to outweigh the risk of developing tardive dyskinesia.

CLINICAL PHARMACOLOGY Metoclopramide stimulates motility of the upper gastrointestinal tract without stimulating gastric, biliary, or pancreatic secretions. Its mode of action is unclear. It seems to sensitize tissues to the action of acetylcholine. The effect of metoclopramide on motility is not dependent on intact vagal innervation, but it can be abolished by anticholinergic drugs. Metoclopramide increases the tone and amplitude of gastric (especially antral) contractions, relaxes the pyloric sphincter and the duodenal bulb, and increases peristalsis of the duodenum and jejunum resulting in accelerated gastric emptying and intestinal transit. It increases the resting tone of the lower esophageal sphincter. It has little, if any, effect on the motility of the colon or gallbladder. In patients with gastroesophageal reflux and low LESP (lower esophageal sphincter pressure), single oral doses of metoclopramide produce dose-related increases in LESP. Effects begin at about 5 mg and increase through 20 mg (the largest dose tested). The increase in LESP from a 5 mg dose lasts about 45 minutes and that of 20 mg lasts between 2 and 3 hours. Increased rate of stomach emptying has been observed with single oral doses of 10 mg. The antiemetic properties of metoclopramide appear to be a result of its antagonism of central and peripheral dopamine receptors. Dopamine produces nausea and vomiting by stimulation of the medullary chemoreceptor trigger zone (CTZ), and metoclopramide blocks stimulation of the CTZ by agents like l-dopa or apomorphine which are known to increase dopamine levels or to possess dopamine-like effects. Metoclopramide also abolishes the slowing of gastric emptying caused by apomorphine. Like the phenothiazines and related drugs, which are also dopamine antagonists, metoclopramide produces sedation and may produce extrapyramidal reactions, although these are comparatively rare (see WARNINGS). Metoclopramide inhibits the central and peripheral effects of apomorphine, induces release of prolactin and causes a transient increase in circulating aldosterone levels, which may be associated with transient fluid retention. The onset of pharmacological action of metoclopramide is 1 to 3 minutes following an intravenous dose, 10 to 15 minutes following intramuscular administration, and 30 to 60 minutes following an oral dose; pharmacological effects persist for 1 to 2 hours. Pharmacokinetics Metoclopramide is rapidly and well absorbed. Relative to an intravenous dose of 20 mg, the absolute oral bioavailability of metoclopramide is 80% ± 15.5% as demonstrated in a crossover study of 18 subjects. Peak plasma concentrations occur at about 1 to 2 hr after a single oral dose. Similar time to peak is observed after individual doses at steady state. In a single dose study of 12 subjects, the area under the drug concentration-time curve increases linearly with doses from 20 to 100 mg. Peak concentrations increase linearly with dose; time to peak concentrations remains the same; whole body clearance is unchanged; and the elimination rate remains the same. The average elimination half-life in individuals with normal renal function is 5 to 6 hr. Linear kinetic processes adequately describe the absorption and elimination of metoclopramide. Chemical Structure Page 2 of 19 reglan® tablets (metoclopramide tablets, USP) 10/8/2009 file://C:\Documents and Settings\batesm\Desktop\fc55823a-cb4c-4cf1-b95d-2248f627a4d3.xml This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda Approximately 85% of the radioactivity of an orally administered dose appears in the urine within 72 hr. Of the 85% eliminated in the urine, about half is present as free or conjugated metoclopramide. The drug is not extensively bound to plasma proteins (about 30%). The whole body volume of distribution is high (about 3.5 L/kg) which suggests extensive distribution of drug to the tissues. Renal impairment affects the clearance of metoclopramide. In a study with patients with varying degrees of renal impairment, a reduction in creatinine clearance was correlated with a reduction in plasma clearance, renal clearance, non-renal clearance, and increase in elimination half-life. The kinetics of metoclopramide in the presence of renal impairment remained linear however. The reduction in clearance as a result of renal impairment suggests that adjustment downward of maintenance dosage should be done to avoid drug accumulation. In pediatric patients, the pharmacodynamics of metoclopramide following oral and intravenous administration are highly variable and a concentration-effect relationship has not been established. There are insufficient reliable data to conclude whether the pharmacokinetics of metoclopramide in adults and the pediatric population are similar. Although there are insufficient data to support the efficacy of metoclopramide in pediatric patients with symptomatic gastroesophageal reflux (GER) or cancer chemotherapy-related nausea and vomiting, its pharmacokinetics have been studied in these patient populations. In an open-label study, six pediatric patients (age range, 3.5 weeks to 5.4 months) with GER received metoclopramide 0.15 mg/kg oral solution every 6 hours for 10 doses. The mean peak plasma concentration of metoclopramide after the tenth dose was 2-fold (56.8 μg/L) higher compared to that observed after the first dose (29 μg/L) indicating drug accumulation with repeated dosing. After the tenth dose, the mean time to reach peak concentrations (2.2 hr), half-life (4.1 hr), clearance (0.67 L/h/kg), and volume of distribution (4.4 L/kg) of metoclopramide were similar to those observed after the first dose. In the youngest patient (age, 3.5 weeks), metoclopramide half-life after the first and the tenth dose (23.1 and 10.3 hr, respectively) was significantly longer compared to other infants due to reduced clearance. This may be attributed to immature hepatic and renal systems at birth. Single intravenous doses of metoclopramide 0.22 to 0.46 mg/kg (mean, 0.35 mg/kg) were administered over 5 minutes to 9 pediatric cancer patients receiving chemotherapy (mean age, 11.7 years; range, 7 to 14 yr) for prophylaxis of cytotoxic-induced vomiting. The metoclopramide plasma concentrations extrapolated to time zero ranged from 65 to 395 μg/L (mean, 152 μg/L). The mean elimination half-life, clearance, and volume of distribution of metoclopramide were 4.4 hr (range, 1.7 to 8.3 hr), 0.56 L/h/kg (range, 0.12 to 1.20 L/h/kg), and 3.0 L/kg (range, 1.0 to 4.8 L/kg), respectively. In another study, nine pediatric cancer patients (age range, 1 to 9 yr) received 4 to 5 intravenous infusions (over 30 minutes) of metoclopramide at a dose of 2 mg/kg to control emesis. After the last dose, the peak serum concentrations of metoclopramide ranged from 1060 to 5680 μg/L.

INDICATIONS AND USAGE The use of reglan tablets is recommended for adults only. Therapy should not exceed 12 weeks in duration. Symptomatic Gastroesophageal Reflux reglan tablets are indicated as short-term (4 to 12 weeks) therapy for adults with symptomatic, documented gastroesophageal reflux who fail to respond to conventional therapy. The principal effect of metoclopramide is on symptoms of postprandial and daytime heartburn with less observed effect on nocturnal symptoms. If symptoms are confined to particular situations, such as following the evening meal, use of metoclopramide as single doses prior to the provocative situation should be considered, rather than using the drug throughout the day. Healing of esophageal ulcers and erosions has been endoscopically demonstrated at the end of a 12-week trial using doses of 15 mg q.i.d. As there is no documented correlation between symptoms and healing of esophageal lesions, patients with documented lesions should be monitored endoscopically. Diabetic Gastroparesis (Diabetic Gastric Stasis) reglan tablets (metoclopramide tablets, USP) is indicated for the relief of symptoms associated with acute and recurrent diabetic gastric stasis. The usual manifestations of delayed gastric emptying (e.g., nausea, vomiting, heartburn, persistent fullness after meals, and anorexia) appear to respond to reglan within different time intervals. Significant relief of nausea occurs early and continues to improve over a three-week period. Relief of vomiting and anorexia may precede the relief of abdominal fullness by one week or more. CONTRAINDICATIONS Metoclopramide should not be used whenever stimulation of gastrointestinal motility might be dangerous, e.g., in the presence of gastrointestinal hemorrhage, mechanical obstruction, or perforation. Metoclopramide is contraindicated in patients with pheochromocytoma because the drug may cause a hypertensive crisis, probably due to release of catecholamines from the tumor. Such hypertensive crises may be controlled by phentolamine. Metoclopramide is contraindicated in patients with known sensitivity or intolerance to the drug. Metoclopramide should not be used in epileptics or patients receiving other drugs which are likely to cause extrapyramidal reactions, since the frequency and severity of seizures or extrapyramidal reactions may be increased. WARNINGS Mental depression has occurred in patients with and without prior history of depression. Symptoms have ranged from mild to severe and have included suicidal ideation and suicide. Metoclopramide should be given to patients with a prior history of depression only if the expected benefits outweigh the potential risks. ® ® ® ® Page 4 of 19 reglan® tablets (metoclopramide tablets, USP) 10/8/2009 file://C:\Documents and Settings\batesm\Desktop\fc55823a-cb4c-4cf1-b95d-2248f627a4d3.xml This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda Extrapyramidal symptoms, manifested primarily as acute dystonic reactions, occur in approximately 1 in 500 patients treated with the usual adult dosages of 30 to 40 mg/day of metoclopramide. These usually are seen during the first 24 to 48 hours of treatment with metoclopramide, occur more frequently in pediatric patients and adult patients less than 30 years of age and are even more frequent at higher doses. These symptoms may include involuntary movements of limbs and facial grimacing, torticollis, oculogyric crisis, rhythmic protrusion of tongue, bulbar type of speech, trismus, or dystonic reactions resembling tetanus. Rarely, dystonic reactions may present as stridor and dyspnea, possibly due to laryngospasm. If these symptoms should occur, inject 50 mg diphenhydramine hydrochloride intramuscularly, and they usually will subside. Benztropine mesylate, 1 to 2 mg intramuscularly, may also be used to reverse these reactions. Parkinsonian-like symptoms have occurred, more commonly within the first 6 months after beginning treatment with metoclopramide, but occasionally after longer periods. These symptoms generally subside within 2 to 3 months following discontinuance of metoclopramide. Patients with preexisting Parkinson's disease should be given metoclopramide cautiously, if at all, since such patients may experience exacerbation of parkinsonian symptoms when taking metoclopramide. Tardive Dyskinesia (see Boxed Warnings) Treatment with metoclopramide can cause tardive dyskinesia (TD), a potentially irreversible and disfiguring disorder characterized by involuntary movements of the face, tongue, or extremities. Although the risk of TD with metoclopramide has not been extensively studied, one published study reported a TD prevalence of 20% among patients treated for at least 12 weeks. Treatment with metoclopramide for longer than 12 weeks should be avoided in all but rare cases where therapeutic benefit is thought to outweigh the risk of developing TD. Although the risk of developing TD in the general population may be increased among the elderly, women, and diabetics, it is not possible to predict which patients will develop metoclopramide- induced TD. Both the risk of developing TD and the likelihood that TD will become irreversible increase with duration of treatment and total cumulative dose. Metoclopramide should be discontinued in patients who develop signs or symptoms of TD. There is no known effective treatment for established cases of TD, although in some patients, TD may remit, partially or completely, within several weeks to months after metoclopramide is withdrawn. Metoclopramide itself may suppress, or partially suppress, the signs of TD, thereby masking the underlying disease process. The effect of this symptomatic suppression upon the long-term course of TD is unknown. Therefore, metoclopramide should not be used for the symptomatic control of TD. Neuroleptic Malignant Syndrome (NMS) There have been rare reports of an uncommon but potentially fatal symptom complex sometimes referred to as Neuroleptic Malignant Syndrome (NMS) associated with metoclopramide. Clinical manifestations of NMS include hyperthermia, muscle rigidity, altered consciousness, and evidence of autonomic instability (irregular pulse or blood pressure, tachycardia, diaphoresis and cardiac arrhythmias). The diagnostic evaluation of patients with this syndrome is complicated. In arriving at a diagnosis, it is important to identify cases where the clinical presentation includes both serious medical illness (e.g., pneumonia, systemic infection, etc.) and untreated or inadequately treated extrapyramidal signs and symptoms (EPS). Other important considerations in the differential diagnosis include central Page 5 of 19 reglan® tablets (metoclopramide tablets, USP) 10/8/2009 file://C:\Documents and Settings\batesm\Desktop\fc55823a-cb4c-4cf1-b95d-2248f627a4d3.xml This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda anticholinergic toxicity, heat stroke, malignant hyperthermia, drug fever and primary central nervous system (CNS) pathology. The management of NMS should include 1) immediate discontinuation of metoclopramide and other drugs not essential to concurrent therapy, 2) intensive symptomatic treatment and medical monitoring, and 3) treatment of any concomitant serious medical problems for which specific treatments are available. Bromocriptine and dantrolene sodium have been used in treatment of NMS, but their effectiveness have not been established (see ADVERSE REACTIONS). PRECAUTIONS General In one study in hypertensive patients, intravenously administered metoclopramide was shown to release catecholamines; hence, caution should be exercised when metoclopramide is used in patients with hypertension. Because metoclopramide produces a transient increase in plasma aldosterone, certain patients, especially those with cirrhosis or congestive heart failure, may be at risk of developing fluid retention and volume overload. If these side effects occur at any time during metoclopramide therapy, the drug should be discontinued. Adverse reactions, especially those involving the nervous system, may occur after stopping the use of reglan . A small number of patients may experience a withdrawal period after stopping reglan that could include dizziness, nervousness, and/or headaches. Information for Patients The use of reglan is recommended for adults only. Metoclopramide may impair the mental and/or physical abilities required for the performance of hazardous tasks such as operating machinery or driving a motor vehicle. The ambulatory patient should be cautioned accordingly. For additional information, patients should be instructed to see the Medication Guide for reglan tablets. Drug Interactions The effects of metoclopramide on gastrointestinal motility are antagonized by anticholinergic drugs and narcotic analgesics. Additive sedative effects can occur when metoclopramide is given with alcohol, sedatives, hypnotics, narcotics, or tranquilizers. The finding that metoclopramide releases catecholamines in patients with essential hypertension suggests that it should be used cautiously, if at all, in patients receiving monoamine oxidase inhibitors. Absorption of drugs from the stomach may be diminished (e.g., digoxin) by metoclopramide, whereas the rate and/or extent of absorption of drugs from the small bowel may be increased (e.g., acetaminophen, tetracycline, levodopa, ethanol, cyclosporine). Gastroparesis (gastric stasis) may be responsible for poor diabetic control in some patients. Exogenously administered insulin may begin to act before food has left the stomach and lead to hypoglycemia. Because the action of metoclopramide will influence the delivery of food to the intestines and thus the rate of absorption, insulin dosage or timing of dosage may require adjustment. ® ® ® ® Page 6 of 19 reglan® tablets (metoclopramide tablets, USP) 10/8/2009 file://C:\Documents and Settings\batesm\Desktop\fc55823a-cb4c-4cf1-b95d-2248f627a4d3.xml This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda Carcinogenesis, Mutagenesis, Impairment of Fertility A 77-week study was conducted in rats with oral doses up to about 40 times the maximum recommended human daily dose. Metoclopramide elevates prolactin levels and the elevation persists during chronic administration. Tissue culture experiments indicate that approximately one-third of human breast cancers are prolactin-dependent in vitro, a factor of potential importance if the prescription of metoclopramide is contemplated in a patient with previously detected breast cancer. Although disturbances such as galactorrhea, amenorrhea, gynecomastia, and impotence have been reported with prolactin-elevating drugs, the clinical significance of elevated serum prolactin levels is unknown for most patients. An increase in mammary neoplasms has been found in rodents after chronic administration of prolactin-stimulating neuroleptic drugs and metoclopramide. Neither clinical studies nor epidemiologic studies conducted to date, however, have shown an association between chronic administration of these drugs and mammary tumorigenesis; the available evidence is too limited to be conclusive at this time. An Ames mutagenicity test performed on metoclopramide was negative. Pregnancy Category B Reproduction studies performed in rats, mice and rabbits by the I.V., I.M., S.C., and oral routes at maximum levels ranging from 12 to 250 times the human dose have demonstrated no impairment of fertility or significant harm to the fetus due to metoclopramide. There are, however, no adequate and well-controlled studies in pregnant women. Because animal reproduction studies are not always predictive of human response, this drug should be used during pregnancy only if clearly needed. Nursing Mothers Metoclopramide is excreted in human milk. Caution should be exercised when metoclopramide is administered to a nursing mother. Pediatric Use Safety and effectiveness in pediatric patients have not been established (see OVERDOSAGE). Care should be exercised in administering metoclopramide to neonates since prolonged clearance may produce excessive serum concentrations (see CLINICAL PHARMACOLOGY - Pharmacokinetics). In addition, neonates have reduced levels of NADH-cytochrome b reductase which, in combination with the aforementioned pharmacokinetic factors, make neonates more susceptible to methemoglobinemia (see OVERDOSAGE). The safety profile of metoclopramide in adults cannot be extrapolated to pediatric patients. Dystonias and other extrapyramidal reactions associated with metoclopramide are more common in the pediatric population than in adults. (See WARNINGS and ADVERSE REACTIONS - Extrapyramidal Reactions.) Geriatric Use Clinical studies of reglan did not include sufficient numbers of subjects aged 65 and over to determine whether elderly subjects respond differently from younger subjects. The risk of developing parkinsonian-like side effects increases with ascending dose. Geriatric patients should receive the lowest dose of reglan that is effective. If parkinsonian-like symptoms develop in a 5 ® ® Page 7 of 19 reglan® tablets (metoclopramide tablets, USP) 10/8/2009 file://C:\Documents and Settings\batesm\Desktop\fc55823a-cb4c-4cf1-b95d-2248f627a4d3.xml This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda geriatric patient receiving reglan , reglan should generally be discontinued before initiating any specific anti-parkinsonian agents (see WARNINGS and DOSAGE AND ADMINISTRATION – For the Relief of Symptomatic Gastroesophageal Reflux). The elderly may be at greater risk for tardive dyskinesia (see WARNINGS – Tardive Dyskinesia). Sedation has been reported in reglan users. Sedation may cause confusion and manifest as over- sedation in the elderly (see CLINICAL PHARMACOLOGY, PRECAUTIONS – Information for Patients and ADVERSE REACTIONS – CNS Effects). reglan is known to be substantially excreted by the kidney, and the risk of toxic reactions to this drug may be greater in patients with impaired renal function (see DOSAGE AND ADMINISTRATION – Use in Patients with Renal or Hepatic Impairment). For these reasons, dose selection for an elderly patient should be cautious, usually starting at the low end of the dosing range, reflecting the greater frequency of decreased renal function, concomitant disease, or other drug therapy in the elderly (see DOSAGE AND ADMINISTRATION – For the Relief of Symptomatic Gastroesophageal Reflux and Use in Patients with Renal or Hepatic Impairment). Other Special Populations Patients with NADH-cytochrome b reductase deficiency are at an increased risk of developing methemoglobinemia and/or sulfhemoglobinemia when metoclopramide is administered. In patients with G6PD deficiency who experience metoclopramide- induced methemoglobinemia, methylene blue treatment is not recommended (see OVERDOSAGE). ADVERSE REACTIONS In general, the incidence of adverse reactions correlates with the dose and duration of metoclopramide administration. The following reactions have been reported, although in most instances, data do not permit an estimate of frequency: CNS Effects Restlessness, drowsiness, fatigue, and lassitude occur in approximately 10% of patients receiving the most commonly prescribed dosage of 10 mg q.i.d. (see PRECAUTIONS). Insomnia, headache, confusion, dizziness, or mental depression with suicidal ideation (see WARNINGS) occur less frequently. The incidence of drowsiness is greater at higher doses. There are isolated reports of convulsive seizures without clearcut relationship to metoclopramide. Rarely, hallucinations have been reported. Extrapyramidal Reactions (EPS) Acute dystonic reactions, the most common type of EPS associated with metoclopramide, occur in approximately 0.2% of patients (1 in 500) treated with 30 to 40 mg of metoclopramide per day. Symptoms include involuntary movements of limbs, facial grimacing, torticollis, oculogyric crisis, rhythmic protrusion of tongue, bulbar type of speech, trismus, opisthotonus (tetanus-like reactions), and, rarely, stridor and dyspnea possibly due to laryngospasm; ordinarily these symptoms are readily reversed by diphenhydramine (see WARNINGS). Parkinsonian-like symptoms may include bradykinesia, tremor, cogwheel rigidity, mask-like facies (see WARNINGS). Tardive dyskinesia most frequently is characterized by involuntary movements of the tongue, face, ® ® 5 Page 8 of 19 reglan® tablets (metoclopramide tablets, USP) 10/8/2009 file://C:\Documents and Settings\batesm\Desktop\fc55823a-cb4c-4cf1-b95d-2248f627a4d3.xml This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda mouth, or jaw, and sometimes by involuntary movements of the trunk and/or extremities; movements may be choreoathetotic in appearance (see WARNINGS). Motor restlessness (akathisia) may consist of feelings of anxiety, agitation, jitteriness, and insomnia, as well as inability to sit still, pacing, foot tapping. These symptoms may disappear spontaneously or respond to a reduction in dosage. Neuroleptic Malignant Syndrome Rare occurrences of neuroleptic malignant syndrome (NMS) have been reported. This potentially fatal syndrome is comprised of the symptom complex of hyperthermia, altered consciousness, muscular rigidity, and autonomic dysfunction (see WARNINGS). Endocrine Disturbances Galactorrhea, amenorrhea, gynecomastia, impotence secondary to hyperprolactinemia (see PRECAUTIONS). Fluid retention secondary to transient elevation of aldosterone (see CLINICAL PHARMACOLOGY). Cardiovascular Hypotension, hypertension, supraventricular tachycardia, bradycardia, fluid retention, acute congestive heart failure and possible AV block (see CONTRAINDICATIONS and PRECAUTIONS). Gastrointestinal Nausea and bowel disturbances, primarily diarrhea. Hepatic Rarely, cases of hepatotoxicity, characterized by such findings as jaundice and altered liver function tests, when metoclopramide was administered with other drugs with known hepatotoxic potential. Renal Urinary frequency and incontinence. Hematologic A few cases of neutropenia, leukopenia, or agranulocytosis, generally without clearcut relationship to metoclopramide. Methemoglobinemia, in adults and especially with overdosage in neonates (see OVERDOSAGE). Sulfhemoglobinemia in adults. Allergic Reactions A few cases of rash, urticaria, or bronchospasm, especially in patients with a history of asthma. Rarely, angioneurotic edema, including glossal or laryngeal edema. Miscellaneous Visual disturbances. Porphyria. OVERDOSAGE Page 9 of 19 reglan® tablets (metoclopramide tablets, USP) 10/8/2009 file://C:\Documents and Settings\batesm\Desktop\fc55823a-cb4c-4cf1-b95d-2248f627a4d3.xml This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda Symptoms of overdosage may include drowsiness, disorientation and extrapyramidal reactions. Anticholinergic or antiparkinson drugs or antihistamines with anticholinergic properties may be helpful in controlling the extrapyramidal reactions. Symptoms are self-limiting and usually disappear within 24 hours. Hemodialysis removes relatively little metoclopramide, probably because of the small amount of the drug in blood relative to tissues. Similarly, continuous ambulatory peritoneal dialysis does not remove significant amounts of drug. It is unlikely that dosage would need to be adjusted to compensate for losses through dialysis. Dialysis is not likely to be an effective method of drug removal in overdose situations. Unintentional overdose due to misadministration has been reported in infants and children with the use of metoclopramide oral solution. While there was no consistent pattern to the reports associated with these overdoses, events included seizures, extrapyramidal reactions, and lethargy. Methemoglobinemia has occurred in premature and full-term neonates who were given overdoses of metoclopramide (1 to 4 mg/kg/day orally, intramuscularly or intravenously for 1 to 3 or more days). Methemoglobinemia can be reversed by the intravenous administration of methylene blue. However, methylene blue may cause hemolytic anemia in patients with G6PD deficiency, which may be fatal (see PRECAUTIONS – Other Special Populations). DOSAGE AND ADMINISTRATION Therapy with reglan tablets should not exceed 12 weeks in duration. For the Relief of Symptomatic Gastroesophageal Reflux Administer from 10 mg to 15 mg reglan (metoclopramide hydrochloride, USP) orally up to q.i.d. 30 minutes before each meal and at bedtime, depending upon symptoms being treated and clinical response (see CLINICAL PHARMACOLOGY and INDICATIONS AND USAGE). If symptoms occur only intermittently or at specific times of the day, use of metoclopramide in single doses up to 20 mg prior to the provoking situation may be preferred rather than continuous treatment. Occasionally, patients (such as elderly patients) who are more sensitive to the therapeutic or adverse effects of metoclopramide will require only 5 mg per dose. Experience with esophageal erosions and ulcerations is limited, but healing has thus far been documented in one controlled trial using q.i.d. therapy at 15 mg/dose, and this regimen should be used when lesions are present, so long as it is tolerated (see ADVERSE REACTIONS). Because of the poor correlation between symptoms and endoscopic appearance of the esophagus, therapy directed at esophageal lesions is best guided by endoscopic evaluation. Therapy longer than 12 weeks has not been evaluated and cannot be recommended. For the Relief of Symptoms Associated with Diabetic Gastroparesis (Diabetic Gastric Stasis) Administer 10 mg of metoclopramide 30 minutes before each meal and at bedtime for two to eight weeks, depending upon response and the likelihood of continued well-being upon drug discontinuation. The initial route of administration should be determined by the severity of the presenting symptoms. If only the earliest manifestations of diabetic gastric stasis are present, oral administration of reglan may be initiated. However, if severe symptoms are present, therapy should begin with metoclopramide injection (consult labeling of the injection prior to initiating parenteral administration). ® ® ® Page 10 of 19 reglan® tablets (metoclopramide tablets, USP) 10/8/2009 file://C:\Documents and Settings\batesm\Desktop\fc55823a-cb4c-4cf1-b95d-2248f627a4d3.xml This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda Administration of metoclopramide injection up to 10 days may be required before symptoms subside, at which time oral administration may be instituted. Since diabetic gastric stasis is frequently recurrent, reglan therapy should be reinstituted at the earliest manifestation. Use in Patients with Renal or Hepatic Impairment Since metoclopramide is excreted principally through the kidneys, in those patients whose creatinine clearance is below 40 mL/min, therapy should be initiated at approximately one-half the recommended dosage. Depending upon clinical efficacy and safety considerations, the dosage may be increased or decreased as appropriate. See OVERDOSAGE section for information regarding dialysis. Metoclopramide undergoes minimal hepatic metabolism, except for simple conjugation. Its safe use has been described in patients with advanced liver disease whose renal function was normal.

s t ructu ral formu l a Didronel® (etidronate disodium) DESCRIPTION: Didronel® tablets contain 400 mg of etidronate disodium, the disodium salt of (1­ hydroxyethylidene) diphosphonic acid, for oral administration. This compound, also known as EHDP, regulates bone metabolism. It is a white powder, highly soluble in water, with a molecular weight of 250 and the following structural formula: Inactive Ingredients: Each tablet contains magnesium stearate, microcrystalline cellulose, and starch. CLINICAL PHARMACOLOGY: Didronel acts primarily on bone. It can inhibit the formation, growth, and dissolution of hydroxyapatite crystals and their amorphous precursors by chemisorption to calcium phosphate surfaces. Inhibition of crystal resorption occurs at lower doses than are required to inhibit crystal growth. Both effects increase as the dose increases. Didronel is not metabolized. The amount of drug absorbed after an oral dose is approximately 3 percent. In normal subjects, plasma half-life (t 1/2 ) of etidronate, based on non-compartmental pharmacokinetics is 1 to 6 hours. Within 24 hours, approximately half the absorbed dose is excreted in urine; the remainder is distributed to bone compartments from which it is slowly eliminated. Animal studies have yielded bone clearance estimates up to 165 days. In humans, the residence time on bone may vary due to such factors as specific metabolic condition and bone type. Unabsorbed drug is excreted intact in the feces. Preclinical studies indicate etidronate disodium does not cross the blood-brain barrier. Didronel therapy does not adversely affect serum levels of parathyroid hormone or calcium. Paget’s Disease: Paget's disease of bone (osteitis deformans) is an idiopathic, progressive disease characterized by abnormal and accelerated bone metabolism in one or more bones. Signs and symptoms may include bone pain and/or deformity, neurologic disorders, elevated cardiac output and other vascular disorders, and increased serum alkaline phosphatase and/or urinary hydroxyproline levels. Bone fractures are common in patients with Paget's disease. Didronel slows accelerated bone turnover (resorption and accretion) in pagetic lesions and, to a lesser extent, in normal bone. This has been demonstrated histologically, scintigraphically, biochemically, and through calcium kinetic and balance studies. Reduced bone turnover is often accompanied by symptomatic improvement, including reduced bone pain. Also, the incidence of pagetic fractures may be reduced, and elevated cardiac output and other vascular disorders may be improved by Didronel therapy. Reference ID: 3728054 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda Heterotopic Ossification: Heterotopic ossification, also referred to as myositis ossificans (circumscripta, progressiva or traumatica), ectopic calcification, periarticular ossification, or paraosteoarthropathy, is characterized by metaplastic osteogenesis. It usually presents with signs of localized inflammation or pain, elevated skin temperature, and redness. When tissues near joints are involved, functional loss may also be present. Heterotopic ossification may occur for no known reason as in myositis ossificans progressiva or may follow a wide variety of surgical, occupational, and sports trauma (for example, hip arthroplasty, spinal cord injury, head injury, burns, and severe thigh bruises). Heterotopic ossification has also been observed in non-traumatic conditions (for example, infections of the central nervous system, peripheral neuropathy, tetanus, biliary cirrhosis, Peyronie's disease, as well as in association with a variety of benign and malignant neoplasms). Clinical trials have demonstrated the efficacy of Didronel in heterotopic ossification following total hip replacement, or due to spinal cord injury. --Heterotopic ossification complicating total hip replacement typically develops radiographically 3 to 8 weeks postoperatively in the pericapsular area of the affected hip joint. The overall incidence is about 50 percent; about one-third of these cases are clinically significant. --Heterotopic ossification due to spinal cord injury typically develops radiographically 1 to 4 months after injury. It occurs below the level of injury, usually at major joints. The overall incidence is about 40 percent; about one-half of these cases are clinically significant. Didronel chemisorbs to calcium hydroxyapatite crystals and their amorphous precursors, blocking the aggregation, growth, and mineralization of these crystals. This is thought to be the mechanism by which Didronel prevents or retards heterotopic ossification. There is no evidence Didronel affects mature heterotopic bone. INDICATIONS AND USAGE: Didronel is indicated for the treatment of symptomatic Paget’s disease of bone and in the prevention and treatment of heterotopic ossification following total hip replacement or due to spinal cord injury. Didronel is not approved for the treatment of osteoporosis. Paget’s Disease: Didronel is indicated for the treatment of symptomatic Paget's disease of bone. Didronel therapy usually arrests or significantly impedes the disease process as evidenced by: --Symptomatic relief, including decreased pain and/or increased mobility (experienced by 3 out of 5 patients). --Reductions in serum alkaline phosphatase and urinary hydroxyproline levels (30 percent or more in 4 out of 5 patients). --Histomorphometry showing reduced numbers of osteoclasts and osteoblasts, and more lamellar bone formation. 2 Reference ID: 3728054 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda --Bone scans showing reduced radionuclide uptake at pagetic lesions. In addition, reductions in pagetically elevated cardiac output and skin temperature have been observed in some patients. In many patients, the disease process will be suppressed for a period of at least 1 year following cessation of therapy. The upper limit of this period has not been determined. The effects of the Didronel treatment in patients with asymptomatic Paget's disease have not been studied. However, Didronel treatment of such patients may be warranted if extensive involvement threatens irreversible neurologic damage, major joints, or major weight-bearing bones. Heterotopic Ossification: Didronel is indicated in the prevention and treatment of heterotopic ossification following total hip replacement or due to spinal cord injury. Didronel reduces the incidence of clinically important heterotopic bone by about two-thirds. Among those patients who form heterotopic bone, Didronel retards the progression of immature lesions and reduces the severity by at least half. Follow-up data (at least 9 months posttherapy) suggest these benefits persist. In total hip replacement patients, Didronel does not promote loosening of the prosthesis or impede trochanteric reattachment. In spinal cord injury patients, Didronel does not inhibit fracture healing or stabilization of the spine. CONTRAINDICATIONS: • Abnormalities of the esophagus which delay esophageal emptying such as stricture or achalasia. • Known hypersensitivity to etidronate disodium or in patients with clinically overt osteomalacia. WARNINGS: General: Upper Gastrointestinal Adverse Reactions: Didronel, like other bisphosphonates administered orally, may cause local irritation of the upper gastrointestinal mucosa. Because of these possible irritant effects and a potential for worsening of the underlying disease, caution should be used when Didronel is given to patients with active upper gastrointestinal problems (such as known Barrett’s esophagus, dysphagia, other esophageal diseases, gastritis, duodenitis or ulcers). Esophageal adverse experiences, such as esophagitis, esophageal ulcers and esophageal erosions, occasionally with bleeding and rarely followed by esophageal stricture or perforation, have been reported in patients receiving treatment with oral bisphosphonates. In some cases, these have been severe and required hospitalization. Physicians should therefore be alert to any signs or symptoms signaling a possible esophageal reaction and patients should be instructed to discontinue Didronel and seek medical attention if they develop dysphagia, odynophagia, retrosternal pain or new or worsening heartburn. 3 Reference ID: 3728054 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda The risk of severe esophageal adverse experiences appears to be greater in patients who lie down after taking oral bisphosphonates and/or who fail to swallow it with the recommended full glass (6 to 8 oz) of water, and/or who continue to take oral bisphosphonates after developing symptoms suggestive of esophageal irritation. Therefore, it is very important that the full dosing instructions are provided to, and understood by, the patient (see DOSAGE AND ADMINISTRATION). In patients who cannot comply with dosing instructions due to mental disability, therapy with Didronel should be used under appropriate supervision. There have been post-marketing reports of gastric and duodenal ulcers with oral bisphosphonate use, some severe and with complications, although no increased risk was observed in controlled clinical trials. Paget’s Disease: In Paget's patients the response to therapy may be of slow onset and continue for months after Didronel therapy is discontinued. Dosage should not be increased prematurely. A 90-day drug-free interval should be provided between courses of therapy. Heterotopic Ossification: No specific warnings. PRECAUTIONS: General: Patients should maintain an adequate nutritional status, particularly an adequate intake of calcium and vitamin D. Therapy has been withheld from some patients with enterocolitis since diarrhea may be experienced, particularly at higher doses. Didronel is not metabolized and is excreted intact via the kidney. Hyperphosphatemia may occur at doses of 10 to 20 mg/kg/day, apparently as a result of drug-related increases in tubular reabsorption of phosphate. Serum phosphate levels generally return to normal 2 to 4 weeks post therapy. There is no experience to specifically guide treatment in patients with impaired renal function. Didronel dosage should be reduced when reductions in glomerular filtration rates are present. Patients with renal impairment should be closely monitored. In approximately 10 percent of patients in clinical trials of Didronel® I. V. Infusion (etidronate disodium) for hypercalcemia of malignancy, occasional, mild-to-moderate abnormalities in renal function (increases of > 0.5 mg/dl serum creatinine) were observed during or immediately after treatment. Didronel suppresses bone turnover, and may retard mineralization of osteoid laid down during the bone accretion process. These effects are dose and time dependent. Osteoid, which may accumulate noticeably at doses of 10 to 20 mg/kg/day, mineralizes normally post therapy. In patients with fractures, especially of long bones, it may be advisable to delay or interrupt treatment until callus is evident. Osteonecrosis of the jaw (ONJ): ONJ, which can occur spontaneously, is generally associated with tooth extraction and/or local infection with delayed healing, and has been reported in patients taking bisphosphonates, including Didronel. Known risk factors for osteonecrosis of the jaw include invasive dental procedures (for example, tooth extraction, dental implants, boney surgery), diagnosis of cancer, concomitant therapies (for example, chemotherapy, corticosteroids, angiogenesis inhibitors), poor oral hygiene, and co-morbid 4 Reference ID: 3728054 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda disorders (for example, periodontal and/or other pre-existing dental disease, anemia, coagulopathy, infection, ill-fitting dentures). The risk of ONJ may increase with duration of exposure to bisphosphonates. For patients requiring invasive dental procedures, discontinuation of bisphosphonate treatment may reduce the risk for ONJ. Clinical judgment of the treating physician and/or oral surgeon should guide the management plan of each patient based on individual benefit/risk assessment. Patients who develop osteonecrosis of the jaw while on bisphosphonate therapy should receive care by an oral surgeon. In these patients, extensive dental surgery to treat ONJ may exacerbate the condition. Discontinuation of bisphosphonate therapy should be considered based on individual benefit/risk assessment. Musculoskeletal Pain: In postmarketing experience, there have been infrequent reports of severe and occasionally incapacitating bone, joint, and/or muscle pain in patients taking bisphosphonates (see ADVERSE REACTIONS). The time to onset of symptoms varied from one day to several months after starting the drug. Most patients had relief of symptoms after stopping medication. A subset had recurrence of symptoms when rechallenged with the same drug or another bisphosphonate. Paget’s Disease: In Paget's patients, treatment regimens exceeding the recommended (see DOSAGE AND ADMINISTRATION) daily maximum dose of 20 mg/kg or continuous administration of medication for periods greater than 6 months may be associated with osteomalacia and an increased risk of fracture. Long bones predominantly affected by lytic lesions, particularly in those patients unresponsive to Didronel therapy, may be especially prone to fracture. Patients with predominantly lytic lesions should be monitored radiographically and biochemically to permit termination of Didronel in those patients unresponsive to treatment. Drug Interactions: There have been isolated reports of patients experiencing increases in their prothrombin times when etidronate was added to warfarin therapy. The majority of these reports concerned variable elevations in prothrombin times without clinically significant sequelae. Although the relevance of these reports and any mechanism of coagulation alterations is unclear, patients on warfarin should have their prothrombin time monitored. Carcinogenesis: Long-term studies in rats have indicated that Didronel is not carcinogenic. Pregnancy: Teratogenic Effects: Pregnancy Category C. In teratology and developmental toxicity studies conducted in rats and rabbits treated with dosages of up to 100 mg/kg (5 to 20 times the clinical dose), no adverse or teratogenic effects have been observed in the offspring. Etidronate disodium has been shown to cause skeletal abnormalities in rats when given at oral dose levels of 300 mg/kg (15 to 60 times the human dose). Other effects on the offspring (including decreased live births) are at dosages that cause significant toxicity in the parent generation and are 25 to 200 times the human dose. The skeletal effects are thought to be the result of the pharmacological effects of the drug on bone. 5 Reference ID: 3728054 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda Bisphosphonates are incorporated into the bone matrix, from which they are gradually released over periods of weeks to years. The amount of bisphosphonate incorporation into adult bone, and hence, the amount available for release back into the systemic circulation, is directly related to the dose and duration of bisphosphonate use. There are no data on fetal risk in humans. However, there is a theoretical risk of fetal harm, predominantly skeletal, if a woman becomes pregnant after completing a course of bisphosphonate therapy. The impact of variables such as time between cessation of bisphosphonate therapy to conception, the particular bisphosphonate used, and the route of administration (intravenous versus oral) on this risk has not been studied. There are no adequate and well-controlled studies in pregnant women. Didronel (etidronate disodium) should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus. Nursing Mothers: It is not known whether this drug is excreted in human milk. Because many drugs are excreted in human milk, caution should be exercised when Didronel is administered to a nursing woman. Pediatric Use: Safety and effectiveness in pediatric patients have not been established. Pediatric patients have been treated with Didronel, at doses recommended for adults, to prevent heterotopic ossifications or soft tissue calcifications. A rachitic syndrome has been reported infrequently at doses of 10 mg/kg/day and more for prolonged periods approaching or exceeding a year. The epiphyseal radiologic changes associated with retarded mineralization of new osteoid and cartilage, and occasional symptoms reported, have been reversible when medication is discontinued. Geriatric Use: Clinical studies of Didronel did not include sufficient numbers of subjects aged 65 and over to determine whether they respond differently from younger subjects. Other reported clinical experience has not identified differences in responses between elderly and younger patients. In general, dose selection for an elderly patient should be cautious, reflecting the greater frequency of decreased hepatic, renal, or cardiac function, and of concomitant disease or other drug therapy. This drug is known to be substantially excreted by the kidney, and the risk of toxic reactions to this drug may be greater in patients with impaired renal function. Because elderly patients are more likely to have decreased renal function, care should be taken when prescribing this drug therapy. As stated in PRECAUTIONS, Didronel dosage should be reduced when reductions in glomerular filtration rates are present. In addition, patients with renal impairment should be closely monitored. ADVERSE REACTIONS: The incidence of gastrointestinal complaints (diarrhea, nausea) is the same for Didronel at 5 mg/kg/day as for placebo, about 1 patient in 15. At 10 to 20 mg/kg/day the incidence may increase to 2 or 3 in 10. These complaints are often alleviated by dividing the total daily dose. Paget’s Disease: In Paget's patients, increased or recurrent bone pain at pagetic sites, and/or the onset of pain at previously asymptomatic sites has been reported. At 5 mg/kg/day about 1 patient in 10 (versus 1 in 15 in the placebo group) report these 6 Reference ID: 3728054 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda phenomena. At higher doses the incidence rises to about 2 in 10. When therapy continues, pain resolves in some patients but persists in others. Heterotopic Ossification: No specific adverse reactions. Worldwide Post-Marketing Experience: The worldwide post-marketing experience for etidronate disodium reflects its use in the following approved indications: Paget's disease, heterotopic ossification, and hypercalcemia of malignancy. It also reflects the use of etidronate disodium for osteoporosis where approved in countries outside the US. Other adverse events that have been reported and were thought to be possibly related to etidronate disodium include the following: alopecia; arthropathies, including arthralgia and arthritis; bone fracture; esophagitis; glossitis; hypersensitivity reactions, including angioedema, follicular eruption, macular rash, maculopapular rash, pruritus, Stevens- Johnson syndrome, toxic epidermal necrolysis, and urticaria; osteomalacia; neuropsychiatric events, including amnesia, confusion, depression, and hallucination; and paresthesias. In patients receiving etidronate disodium, there have been rare reports of agranulocytosis, pancytopenia, and a report of leukopenia with recurrence on rechallenge. In addition, there have been rare reports of exacerbation of asthma. Exacerbation of existing peptic ulcer disease including perforation has been reported rarely. In osteoporosis clinical trials, headache, gastritis, leg cramps, and arthralgia occurred at a significantly greater incidence in patients who received etidronate as compared with those who received placebo. OVERDOSAGE: Clinical experience with acute Didronel overdosage is extremely limited. Decreases in serum calcium following substantial overdosage may be expected in some patients. Signs and symptoms of hypocalcemia also may occur in some of these patients. Some patients may develop vomiting. In one event, an 18-year-old female who ingested an estimated single dose of 4000 to 6000 mg (67 to 100 mg/kg) of Didronel was reported to be mildly hypocalcemic (7.52 mg/dl) and experienced paresthesia of the fingers. Hypocalcemia resolved 6 hours after lavage and treatment with intravenous calcium gluconate. A 92-year­ old female who accidentally received 1600 mg of etidronate disodium per day for 3.5 days experienced marked diarrhea and required treatment for electrolyte imbalance. Orally administered etidronate disodium may cause hematologic abnormalities in some patients (see ADVERSE REACTIONS). Etidronate disodium suppresses bone turnover and may retard mineralization of osteoid laid down during the bone accretion process. These effects are dose and time dependent. Osteoid which may accumulate noticeably at doses of 10 to 20 mg/kg/day of chronic, continuous dosing mineralizes normally posttherapy. Prolonged continuous treatment (chronic overdosage) has been reported to cause nephrotic syndrome and fracture. Gastric lavage may remove unabsorbed drug. Standard procedures for treating hypocalcemia, including the administration of Ca++ intravenously, would be expected to restore physiologic amounts of ionized calcium and relieve signs and symptoms of hypocalcemia. Such treatment has been effective. 7 Reference ID: 3728054 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda DOSAGE AND ADMINISTRATION: Didronel should be taken as a single, oral dose. As with other bisphosphonates, it is recommended that Didronel should be swallowed with a full glass of water (6 to 8 oz). Patients should not lie down after taking the medication. However, should gastrointestinal discomfort occur, the dose may be divided. To maximize absorption, patients should avoid taking the following items within two hours of dosing: --Food, especially food high in calcium, such as milk or milk products. --Vitamins with mineral supplements or antacids which are high in metals such as calcium, iron, magnesium, or aluminum. Paget’s Disease: Initial Treatment Regimens: 5 to 10 mg/kg/day, not to exceed 6 months, or 11 to 20 mg/kg/day, not to exceed 3 months. The recommended initial dose is 5 mg/kg/day for a period not to exceed 6 months. Doses above 10 mg/kg/day should be reserved for when 1) lower doses are ineffective or 2) there is an overriding need to suppress rapid bone turnover (especially when irreversible neurologic damage is possible) or reduce elevated cardiac output. Doses in excess of 20 mg/kg/day are not recommended. Retreatment Guidelines: Retreatment should be initiated only after 1) a Didronel-free period of at least 90 days and 2) there is biochemical, symptomatic or other evidence of active disease process. It is advisable to monitor patients every 3 to 6 months although some patients may go drug free for extended periods. Retreatment regimens are the same as for initial treatment. For most patients the original dose will be adequate for retreatment. If not, consideration should be given to increasing the dose within the recommended guidelines. Heterotopic Ossification: The following treatment regimens have been shown to be effective: --Total Hip Replacement Patients: 20 mg/kg/day for 1 month before and 3 months after surgery (4 months total). --Spinal Cord Injured Patients: 20 mg/kg/day for 2 weeks followed by 10 mg/kg/day for 10 weeks (12 weeks total). Didronel therapy should begin as soon as medically feasible following the injury, preferably prior to evidence of heterotopic ossification. Retreatment has not been studied.

Procter & Gamble Pharmaceuticals Revised May 2005 Didronel® (etidronate disodium) DESCRIPTION: Didronel tablets contain either 200 mg or 400 mg of etidronate disodium, the disodium salt of (1-hydroxyethylidene) diphosphonic acid, for oral administration. This compound, also known as EHDP, regulates bone metabolism. It is a white powder, highly soluble in water, with a molecular weight of 250 and the following structural formula: H O P C P OH O H O Na O O Na O C H3 Inactive Ingredients: Each tablet contains magnesium stearate, microcrystalline cellulose, and starch. CLINICAL PHARMACOLOGY: Didronel acts primarily on bone. It can inhibit the formation, growth, and dissolution of hydroxyapatite crystals and their amorphous precursors by chemisorption to calcium phosphate surfaces. Inhibition of crystal resorption occurs at lower doses than are required to inhibit crystal growth. Both effects increase as the dose increases. Didronel is not metabolized. The amount of drug absorbed after an oral dose is approximately 3%. In normal subjects, plasma half-life (t1/2) of etidronate, based on non- compartmental pharmacokinetics is 1 to 6 hours. Within 24 hours, approximately half the absorbed dose is excreted in urine; the remainder is distributed to bone compartments from which it is slowly eliminated. Animal studies have yielded bone clearance estimates up to 165 days. In humans, the residence time on bone may vary due to such factors as specific metabolic condition and bone type. Unabsorbed drug is excreted intact in the feces. Preclinical studies indicate etidronate disodium does not cross the blood-brain barrier. Didronel therapy does not adversely affect serum levels of parathyroid hormone or calcium. Paget’s Disease: Paget's disease of bone (osteitis deformans) is an idiopathic, progressive disease characterized by abnormal and accelerated bone metabolism in one or more bones. Signs and symptoms may include bone pain and/or deformity, neurologic disorders, elevated cardiac output and other vascular disorders, and increased serum alkaline phosphatase and/or urinary hydroxyproline levels. Bone fractures are common in patients with Paget's disease. Didronel slows accelerated bone turnover (resorption and accretion) in pagetic lesions and, to a lesser extent, in normal bone. This has been demonstrated histologically, scintigraphically, biochemically, and through calcium kinetic and balance studies. Reduced bone turnover is often accompanied by symptomatic improvement, including reduced bone pain. Also, the incidence of pagetic fractures may be reduced, and elevated cardiac output and other vascular disorders may be improved by Didronel therapy. This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda Didronel (etidronate disodium) Procter & Gamble Pharmaceuticals Revised May 2005 2 Heterotopic Ossification: Heterotopic ossification, also referred to as myositis ossificans (circumscripta, progressiva or traumatica), ectopic calcification, periarticular ossification, or paraosteoarthropathy, is characterized by metaplastic osteogenesis. It usually presents with signs of localized inflammation or pain, elevated skin temperature, and redness. When tissues near joints are involved, functional loss may also be present. Heterotopic ossification may occur for no known reason as in myositis ossificans progressiva or may follow a wide variety of surgical, occupational, and sports trauma (e.g., hip arthroplasty, spinal cord injury, head injury, burns, and severe thigh bruises). Heterotopic ossification has also been observed in non-traumatic conditions (e.g., infections of the central nervous system, peripheral neuropathy, tetanus, biliary cirrhosis, Peyronie's disease, as well as in association with a variety of benign and malignant neoplasms). Clinical trials have demonstrated the efficacy of Didronel in heterotopic ossification following total hip replacement, or due to spinal cord injury. --Heterotopic ossification complicating total hip replacement typically develops radiographically 3 to 8 weeks postoperatively in the pericapsular area of the affected hip joint. The overall incidence is about 50%; about one-third of these cases are clinically significant. --Heterotopic ossification due to spinal cord injury typically develops radiographically 1 to 4 months after injury. It occurs below the level of injury, usually at major joints. The overall incidence is about 40%; about one-half of these cases are clinically significant. Didronel chemisorbs to calcium hydroxyapatite crystals and their amorphous precursors, blocking the aggregation, growth, and mineralization of these crystals. This is thought to be the mechanism by which Didronel prevents or retards heterotopic ossification. There is no evidence Didronel affects mature heterotopic bone. INDICATIONS AND USAGE: Didronel is indicated for the treatment of symptomatic Paget’s disease of bone and in the prevention and treatment of heterotopic ossification following total hip replacement or due to spinal cord injury. Didronel is not approved for the treatment of osteoporosis. Paget’s Disease: Didronel is indicated for the treatment of symptomatic Paget's disease of bone. Didronel therapy usually arrests or significantly impedes the disease process as evidenced by: --Symptomatic relief, including decreased pain and/or increased mobility (experienced by 3 out of 5 patients). --Reductions in serum alkaline phosphatase and urinary hydroxyproline levels (30% or more in 4 out of 5 patients). --Histomorphometry showing reduced numbers of osteoclasts and osteoblasts, and more lamellar bone formation. This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda Didronel (etidronate disodium) Procter & Gamble Pharmaceuticals Revised May 2005 3 --Bone scans showing reduced radionuclide uptake at pagetic lesions. In addition, reductions in pagetically elevated cardiac output and skin temperature have been observed in some patients. In many patients, the disease process will be suppressed for a period of at least 1 year following cessation of therapy. The upper limit of this period has not been determined. The effects of the Didronel treatment in patients with asymptomatic Paget's disease have not been studied. However, Didronel treatment of such patients may be warranted if extensive involvement threatens irreversible neurologic damage, major joints, or major weight-bearing bones. Heterotopic Ossification: Didronel is indicated in the prevention and treatment of heterotopic ossification following total hip replacement or due to spinal cord injury. Didronel reduces the incidence of clinically important heterotopic bone by about two-thirds. Among those patients who form heterotopic bone, Didronel retards the progression of immature lesions and reduces the severity by at least half. Follow-up data (at least 9 months posttherapy) suggest these benefits persist. In total hip replacement patients, Didronel does not promote loosening of the prosthesis or impede trochanteric reattachment. In spinal cord injury patients, Didronel does not inhibit fracture healing or stabilization of the spine. CONTRAINDICATIONS: Didronel tablets are contraindicated in patients with known hypersensitivity to etidronate disodium or in patients with clinically overt osteomalacia. WARNINGS: Paget’s Disease: In Paget's patients the response to therapy may be of slow onset and continue for months after Didronel therapy is discontinued. Dosage should not be increased prematurely. A 90-day drug-free interval should be provided between courses of therapy. Heterotopic Ossification: No specific warnings. PRECAUTIONS: General: Patients should maintain an adequate nutritional status, particularly an adequate intake of calcium and vitamin D. Therapy has been withheld from some patients with enterocolitis since diarrhea may be experienced, particularly at higher doses. Didronel is not metabolized and is excreted intact via the kidney. Hyperphosphatemia may occur at doses of 10 to 20 mg/kg/day, apparently as a result of drug-related increases in tubular reabsorption of phosphate. Serum phosphate levels generally return to normal 2 to 4 weeks posttherapy. There is no experience to specifically guide treatment in patients with impaired renal function. Didronel dosage should be reduced when reductions in This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda Didronel (etidronate disodium) Procter & Gamble Pharmaceuticals Revised May 2005 4 glomerular filtration rates are present. Patients with renal impairment should be closely monitored. In approximately 10% of patients in clinical trials of Didronel® I. V. Infusion (etidronate disodium) for hypercalcemia of malignancy, occasional, mild-to-moderate abnormalities in renal function (increases of > 0.5 mg/dl serum creatinine) were observed during or immediately after treatment. Didronel suppresses bone turnover, and may retard mineralization of osteoid laid down during the bone accretion process. These effects are dose and time dependent. Osteoid, which may accumulate noticeably at doses of 10 to 20 mg/kg/day, mineralizes normally posttherapy. In patients with fractures, especially of long bones, it may be advisable to delay or interrupt treatment until callus is evident. Osteonecrosis, primarily in the jaw, has been reported in patients treated with bisphosphonates. Most cases have been in cancer patients undergoing dental procedures such as tooth extraction, but some have occurred in patients with postmenopausal osteoporosis or other diagnoses. Most reported cases have been in patients treated with bisphosphonates intravenously but some have been in patients treated orally. For patients requiring dental procedures, there are no data available to suggest whether discontinuation of bisphosphonate treatment, prior to the procedure, reduces the risk of osteonecrosis of the jaw. Clinical judgment should guide the management plan of each patient based on individual benefit/risk assessment. Musculoskeletal Pain: In postmarketing experience, there have been infrequent reports of severe and occasionally incapacitating bone, joint, and/or muscle pain in patients taking bisphosphonates (see ADVERSE REACTIONS). The time to onset of symptoms varied from one day to several months after starting the drug. Most patients had relief of symptoms after stopping medication. A subset had recurrence of symptoms when rechallenged with the same drug or another bisphosphonate. Paget’s Disease: In Paget's patients, treatment regimens exceeding the recommended (see DOSAGE AND ADMINISTRATION) daily maximum dose of 20 mg/kg or continuous administration of medication for periods greater than 6 months may be associated with osteomalacia and an increased risk of fracture. Long bones predominantly affected by lytic lesions, particularly in those patients unresponsive to Didronel therapy, may be especially prone to fracture. Patients with predominantly lytic lesions should be monitored radiographically and biochemically to permit termination of Didronel in those patients unresponsive to treatment. Drug Interactions: There have been isolated reports of patients experiencing increases in their prothrombin times when etidronate was added to warfarin therapy. The majority of these reports concerned variable elevations in prothrombin times without clinically significant sequelae. Although the relevance of these reports and any mechanism of coagulation alterations is unclear, patients on warfarin should have their prothrombin time monitored. This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda Didronel (etidronate disodium) Procter & Gamble Pharmaceuticals Revised May 2005 5 Carcinogenesis: Long-term studies in rats have indicated that Didronel is not carcinogenic. Pregnancy: Teratogenic Effects: Pregnancy Category C. In teratology and developmental toxicity studies conducted in rats and rabbits treated with dosages of up to 100 mg/kg (5 to 20 times the clinical dose), no adverse or teratogenic effects have been observed in the offspring. Etidronate disodium has been shown to cause skeletal abnormalities in rats when given at oral dose levels of 300 mg/kg (15 to 60 times the human dose). Other effects on the offspring (including decreased live births) are at dosages that cause significant toxicity in the parent generation and are 25 to 200 times the human dose. The skeletal effects are thought to be the result of the pharmacological effects of the drug on bone. Bisphosphonates are incorporated into the bone matrix, from which they are gradually released over periods of weeks to years. The amount of bisphosphonate incorporation into adult bone, and hence, the amount available for release back into the systemic circulation, is directly related to the dose and duration of bisphosphonate use. There are no data on fetal risk in humans. However, there is a theoretical risk of fetal harm, predominantly skeletal, if a woman becomes pregnant after completing a course of bisphosphonate therapy. The impact of variables such as time between cessation of bisphosphonate therapy to conception, the particular bisphosphonate used, and the route of administration (intravenous versus oral) on this risk has not been studied. There are no adequate and well-controlled studies in pregnant women. Didronel (etidronate disodium) should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus. Nursing Mothers: It is not known whether this drug is excreted in human milk. Because many drugs are excreted in human milk, caution should be exercised when Didronel is administered to a nursing woman. Pediatric Use: Safety and effectiveness in pediatric patients have not been established. Pediatric patients have been treated with Didronel, at doses recommended for adults, to prevent heterotopic ossifications or soft tissue calcifications. A rachitic syndrome has been reported infrequently at doses of 10 mg/kg/day and more for prolonged periods approaching or exceeding a year. The epiphyseal radiologic changes associated with retarded mineralization of new osteoid and cartilage, and occasional symptoms reported, have been reversible when medication is discontinued. Geriatric Use: Clinical studies of Didronel did not include sufficient numbers of subjects aged 65 and over to determine whether they respond differently from younger subjects. Other reported clinical experience has not identified differences in responses between elderly and younger patients. In general, dose selection for an elderly patient should be cautious, reflecting the greater frequency of decreased hepatic, renal, or cardiac function, and of concomitant disease or other drug therapy. This drug is known to be substantially excreted by the kidney, and the risk of toxic reactions to this drug may be greater in patients with impaired renal function. Because elderly patients are more likely to have decreased renal function, care should be taken when prescribing this drug therapy. As This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda Didronel (etidronate disodium) Procter & Gamble Pharmaceuticals Revised May 2005 6 stated in PRECAUTIONS, Didronel dosage should be reduced when reductions in glomerular filtration rates are present. In addition, patients with renal impairment should be closely monitored. ADVERSE REACTIONS: The incidence of gastrointestinal complaints (diarrhea, nausea) is the same for Didronel at 5 mg/kg/day as for placebo, about 1 patient in 15. At 10 to 20 mg/kg/day the incidence may increase to 2 or 3 in 10. These complaints are often alleviated by dividing the total daily dose. Paget’s Disease: In Paget's patients, increased or recurrent bone pain at pagetic sites, and/or the onset of pain at previously asymptomatic sites has been reported. At 5 mg/kg/day about 1 patient in 10 (versus 1 in 15 in the placebo group) report these phenomena. At higher doses the incidence rises to about 2 in 10. When therapy continues, pain resolves in some patients but persists in others. Heterotopic Ossification: No specific adverse reactions. Worldwide Postmarketing Experience: The worldwide postmarketing experience for etidronate disodium reflects its use in the following approved indications: Paget's disease, heterotopic ossification, and hypercalcemia of malignancy. It also reflects the use of etidronate disodium for osteoporosis where approved in countries outside the US. Other adverse events that have been reported and were thought to be possibly related to etidronate disodium include the following: alopecia; arthropathies, including arthralgia and arthritis; bone fracture; esophagitis; glossitis; hypersensitivity reactions, including angioedema, follicular eruption, macular rash, maculopapular rash, pruritus, a single case of Stevens-Johnson syndrome, and urticaria; osteomalacia; neuropsychiatric events, including amnesia, confusion, depression, and hallucination; and paresthesias. In patients receiving etidronate disodium, there have been rare reports of agranulocytosis, pancytopenia, and a report of leukopenia with recurrence on rechallenge. In addition, there have been rare reports of exacerbation of asthma. Exacerbation of existing peptic ulcer disease has been reported in a few patients. In one patient, perforation also occurred. In osteoporosis clinical trials, headache, gastritis, leg cramps, and arthralgia occurred at a significantly greater incidence in patients who received etidronate as compared with those who received placebo. OVERDOSAGE: Clinical experience with acute Didronel overdosage is extremely limited. Decreases in serum calcium following substantial overdosage may be expected in some patients. Signs and symptoms of hypocalcemia also may occur in some of these patients. Some patients may develop vomiting. In one event, an 18-year-old female who ingested an estimated single dose of 4000 to 6000 mg (67 to 100 mg/kg) of Didronel was reported to be mildly hypocalcemic (7.52 mg/dl) and experienced paresthesia of the fingers. Hypocalcemia resolved 6 hours after lavage and treatment with intravenous calcium gluconate. A 92-year-old female who accidentally received 1600 mg of etidronate disodium per day for 3.5 days experienced marked diarrhea and required treatment for electrolyte imbalance. Orally administered etidronate disodium may cause hematologic abnormalities in some patients (see ADVERSE REACTIONS). This label may not be the latest approved by FDA.

reglan® tablets (metoclopramide tablets, USP) Rx Only WARNING: TARDIVE DYSKINESIA Treatment with metoclopramide can cause tardive dyskinesia, a serious movement disorder that is often irreversible. The risk of developing tardive dyskinesia increases with duration of treatment and total cumulative dose. Metoclopramide therapy should be discontinued in patients who develop signs or symptoms of tardive dyskinesia. There is no known treatment for tardive dyskinesia. In some patients, symptoms may lessen or resolve after metoclopramide treatment is stopped. Treatment with metoclopramide for longer than 12 weeks should be avoided in all but rare cases where therapeutic benefit is thought to outweigh the risk of developing tardive dyskinesia. See WARNINGS DESCRIPTION For oral administration, reglan® tablets (metoclopramide tablets, USP) 10 mg are white, scored, capsule-shaped tablets engraved REGLAN on one side and SP 10 on the opposite side. Each tablet contains: Metoclopramide base .................................................. 10 mg (as the monohydrochloride monohydrate) Inactive Ingredients Magnesium Stearate, Mannitol, Microcrystalline Cellulose, Stearic Acid. reglan® tablets (metoclopramide tablets, USP) 5 mg are green, elliptical-shaped tablets engraved REGLAN 5 on one side and SP on the opposite side. Each tablet contains: Metoclopramide base .................................................... 5 mg (as the monohydrochloride monohydrate) Inactive Ingredients Corn starch, D&C Yellow 10 Aluminum Lake, FD&C Blue 1 Aluminum Lake, Lactose, Microcrystalline Cellulose, Silicon Dioxide, Stearic Acid. Metoclopramide hydrochloride is a white crystalline, odorless substance, freely soluble in water. Chemically, it is 4-amino-5- chloro-N-[2-(diethylamino)ethyl]-2-methoxy benzamide monohydrochloride monohydrate. Its molecular formula is C14H22CIN3O2•HCl•H2O. Its molecular weight is 354.3. REGLAN® - Package Insert Page 1 of 12 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda Structural Formula CLINICAL PHARMACOLOGY Metoclopramide stimulates motility of the upper gastrointestinal tract without stimulating gastric, biliary, or pancreatic secretions. Its mode of action is unclear. It seems to sensitize tissues to the action of acetylcholine. The effect of metoclopramide on motility is not dependent on intact vagal innervation, but it can be abolished by anticholinergic drugs. Metoclopramide increases the tone and amplitude of gastric (especially antral) contractions, relaxes the pyloric sphincter and the duodenal bulb, and increases peristalsis of the duodenum and jejunum resulting in accelerated gastric emptying and intestinal transit. It increases the resting tone of the lower esophageal sphincter. It has little, if any, effect on the motility of the colon or gallbladder. In patients with gastroesophageal reflux and low LESP (lower esophageal sphincter pressure), single oral doses of metoclopramide produce dose-related increases in LESP. Effects begin at about 5 mg and increase through 20 mg (the largest dose tested). The increase in LESP from a 5 mg dose lasts about 45 minutes and that of 20 mg lasts between 2 and 3 hours. Increased rate of stomach emptying has been observed with single oral doses of 10 mg. The antiemetic properties of metoclopramide appear to be a result of its antagonism of central and peripheral dopamine receptors. Dopamine produces nausea and vomiting by stimulation of the medullary chemoreceptor trigger zone (CTZ), and metoclopramide blocks stimulation of the CTZ by agents like l-dopa or apomorphine which are known to increase dopamine levels or to possess dopamine-like effects. Metoclopramide also abolishes the slowing of gastric emptying caused by apomorphine. Like the phenothiazines and related drugs, which are also dopamine antagonists, metoclopramide produces sedation and may produce extrapyramidal reactions, although these are comparatively rare (see WARNINGS). Metoclopramide inhibits the central and peripheral effects of apomorphine, induces release of prolactin and causes a transient increase in circulating aldosterone levels, which may be associated with transient fluid retention. The onset of pharmacological action of metoclopramide is 1 to 3 minutes following an intravenous dose, 10 to 15 minutes following intramuscular administration, and 30 to 60 minutes following an oral dose; pharmacological effects persist for 1 to 2 hours. Pharmacokinetics Metoclopramide is rapidly and well absorbed. Relative to an intravenous dose of 20 mg, the absolute oral bioavailability of metoclopramide is 80% ± 15.5% as demonstrated in a crossover study of 18 subjects. Peak plasma concentrations occur at about 1 to 2 hr after a single oral dose. Similar time to peak is observed after individual doses at steady state. In a single dose study of 12 subjects, the area under the drug concentration-time curve increases linearly with doses from 20 to 100 mg. Peak concentrations increase linearly with dose; time to peak concentrations remains the same; whole body clearance is unchanged; and the elimination rate remains the same. The average elimination half-life in individuals with normal renal function is 5 to 6 hr. Linear kinetic processes adequately describe the absorption and elimination of metoclopramide. REGLAN® - Package Insert Page 2 of 12 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda Approximately 85% of the radioactivity of an orally administered dose appears in the urine within 72 hr. Of the 85% eliminated in the urine, about half is present as free or conjugated metoclopramide. The drug is not extensively bound to plasma proteins (about 30%). The whole body volume of distribution is high (about 3.5 L/kg) which suggests extensive distribution of drug to the tissues. Renal impairment affects the clearance of metoclopramide. In a study with patients with varying degrees of renal impairment, a reduction in creatinine clearance was correlated with a reduction in plasma clearance, renal clearance, non-renal clearance, and increase in elimination half-life. The kinetics of metoclopramide in the presence of renal impairment remained linear however. The reduction in clearance as a result of renal impairment suggests that adjustment downward of maintenance dosage should be done to avoid drug accumulation. Adult Pharmacokinetic Data Parameter Value Vd (L/kg) Plasma Protein Binding t1/2 (hr) Oral Bioavailability ~ 3.5 ~ 30% 5 to 6 80%±15.5% In pediatric patients, the pharmacodynamics of metoclopramide following oral and intravenous administration are highly variable and a concentration-effect relationship has not been established. There are insufficient reliable data to conclude whether the pharmacokinetics of metoclopramide in adults and the pediatric population are similar. Although there are insufficient data to support the efficacy of metoclopramide in pediatric patients with symptomatic gastroesophageal reflux (GER) or cancer chemotherapy-related nausea and vomiting, its pharmacokinetics have been studied in these patient populations. In an open-label study, six pediatric patients (age range, 3.5 weeks to 5.4 months) with GER received metoclopramide 0.15 mg/kg oral solution every 6 hours for 10 doses. The mean peak plasma concentration of metoclopramide after the tenth dose was 2-fold (56.8 μg/L) higher compared to that observed after the first dose (29 μg/L) indicating drug accumulation with repeated dosing. After the tenth dose, the mean time to reach peak concentrations (2.2 hr), half- life (4.1 hr), clearance (0.67 L/h/kg), and volume of distribution (4.4 L/kg) of metoclopramide were similar to those observed after the first dose. In the youngest patient (age, 3.5 weeks), metoclopramide half-life after the first and the tenth dose (23.1 and 10.3 hr, respectively) was significantly longer compared to other infants due to reduced clearance. This may be attributed to immature hepatic and renal systems at birth. Single intravenous doses of metoclopramide 0.22 to 0.46 mg/kg (mean, 0.35 mg/kg) were administered over 5 minutes to 9 pediatric cancer patients receiving chemotherapy (mean age, 11.7 years; range, 7 to 14 yr) for prophylaxis of cytotoxic-induced vomiting. The metoclopramide plasma concentrations extrapolated to time zero ranged from 65 to 395 μg/L (mean, 152 μg/L). The mean elimination half-life, clearance, and volume of distribution of metoclopramide were 4.4 hr (range, 1.7 to 8.3 hr), 0.56 L/h/kg (range, 0.12 to 1.20 L/h/kg), and 3.0 L/kg (range, 1.0 to 4.8 L/kg), respectively. In another study, nine pediatric cancer patients (age range, 1 to 9 yr) received 4 to 5 intravenous infusions (over 30 minutes) of metoclopramide at a dose of 2 mg/kg to control emesis. After the last dose, the peak serum concentrations of metoclopramide ranged from REGLAN® - Package Insert Page 3 of 12 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda 1060 to 5680 μg/L. The mean elimination half-life, clearance, and volume of distribution of metoclopramide were 4.5 hr (range, 2.0 to 12.5 hr), 0.37 L/h/kg (range, 0.10 to 1.24 L/h/kg), and 1.93 L/kg (range, 0.95 to 5.50 L/kg), respectively. INDICATIONS AND USAGE The use of reglan® tablets is recommended for adults only. Therapy should not exceed 12 weeks in duration. Symptomatic Gastroesophageal Reflux reglan® tablets are indicated as short-term (4 to 12 weeks) therapy for adults with symptomatic, documented gastroesophageal reflux who fail to respond to conventional therapy. The principal effect of metoclopramide is on symptoms of postprandial and daytime heartburn with less observed effect on nocturnal symptoms. If symptoms are confined to particular situations, such as following the evening meal, use of metoclopramide as single doses prior to the provocative situation should be considered, rather than using the drug throughout the day. Healing of esophageal ulcers and erosions has been endoscopically demonstrated at the end of a 12-week trial using doses of 15 mg q.i.d. As there is no documented correlation between symptoms and healing of esophageal lesions, patients with documented lesions should be monitored endoscopically. Diabetic Gastroparesis (Diabetic Gastric Stasis) reglan® tablets (metoclopramide tablets, USP) is indicated for the relief of symptoms associated with acute and recurrent diabetic gastric stasis. The usual manifestations of delayed gastric emptying (e.g., nausea, vomiting, heartburn, persistent fullness after meals, and anorexia) appear to respond to reglan® within different time intervals. Significant relief of nausea occurs early and continues to improve over a three-week period. Relief of vomiting and anorexia may precede the relief of abdominal fullness by one week or more. CONTRAINDICATIONS Metoclopramide should not be used whenever stimulation of gastrointestinal motility might be dangerous, e.g., in the presence of gastrointestinal hemorrhage, mechanical obstruction, or perforation. Metoclopramide is contraindicated in patients with pheochromocytoma because the drug may cause a hypertensive crisis, probably due to release of catecholamines from the tumor. Such hypertensive crises may be controlled by phentolamine. Metoclopramide is contraindicated in patients with known sensitivity or intolerance to the drug. Metoclopramide should not be used in epileptics or patients receiving other drugs which are likely to cause extrapyramidal reactions, since the frequency and severity of seizures or extrapyramidal reactions may be increased. WARNINGS Mental depression has occurred in patients with and without prior history of depression. Symptoms have ranged from mild to severe and have included suicidal ideation and suicide. Metoclopramide should be given to patients with a prior history of depression only if the expected benefits outweigh the potential risks. REGLAN® - Package Insert Page 4 of 12 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda Extrapyramidal symptoms, manifested primarily as acute dystonic reactions, occur in approximately 1 in 500 patients treated with the usual adult dosages of 30 to 40 mg/day of metoclopramide. These usually are seen during the first 24 to 48 hours of treatment with metoclopramide, occur more frequently in pediatric patients and adult patients less than 30 years of age and are even more frequent at higher doses. These symptoms may include involuntary movements of limbs and facial grimacing, torticollis, oculogyric crisis, rhythmic protrusion of tongue, bulbar type of speech, trismus, or dystonic reactions resembling tetanus. Rarely, dystonic reactions may present as stridor and dyspnea, possibly due to laryngospasm. If these symptoms should occur, inject 50 mg diphenhydramine hydrochloride intramuscularly, and they usually will subside. Benztropine mesylate, 1 to 2 mg intramuscularly, may also be used to reverse these reactions. Parkinsonian-like symptoms have occurred, more commonly within the first 6 months after beginning treatment with metoclopramide, but occasionally after longer periods. These symptoms generally subside within 2 to 3 months following discontinuance of metoclopramide. Patients with preexisting Parkinson’s disease should be given metoclopramide cautiously, if at all, since such patients may experience exacerbation of parkinsonian symptoms when taking metoclopramide. Tardive Dyskinesia (see Boxed Warnings) Treatment with metoclopramide can cause tardive dyskinesia (TD), a potentially irreversible and disfiguring disorder characterized by involuntary movements of the face, tongue, or extremities. Although the risk of TD with metoclopramide has not been extensively studied, one published study reported a TD prevalence of 20% among patients treated for at least 12 weeks. Treatment with metoclopramide for longer than 12 weeks should be avoided in all but rare cases where therapeutic benefit is thought to outweigh the risk of developing TD. Although the risk of developing TD in the general population may be increased among the elderly, women, and diabetics, it is not possible to predict which patients will develop metoclopramide-induced TD. Both the risk of developing TD and the likelihood that TD will become irreversible increase with duration of treatment and total cumulative dose. Metoclopramide should be discontinued in patients who develop signs or symptoms of TD. There is no known effective treatment for established cases of TD, although in some patients, TD may remit, partially or completely, within several weeks to months after metoclopramide is withdrawn. Metoclopramide itself may suppress, or partially suppress, the signs of TD, thereby masking the underlying disease process. The effect of this symptomatic suppression upon the long-term course of TD is unknown. Therefore, metoclopramide should not be used for the symptomatic control of TD. Neuroleptic Malignant Syndrome (NMS) There have been rare reports of an uncommon but potentially fatal symptom complex sometimes referred to as Neuroleptic Malignant Syndrome (NMS) associated with metoclopramide. Clinical manifestations of NMS include hyperthermia, muscle rigidity, altered consciousness, and evidence of autonomic instability (irregular pulse or blood pressure, tachycardia, diaphoresis and cardiac arrhythmias). REGLAN® - Package Insert Page 5 of 12 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda The diagnostic evaluation of patients with this syndrome is complicated. In arriving at a diagnosis, it is important to identify cases where the clinical presentation includes both serious medical illness (e.g., pneumonia, systemic infection, etc.) and untreated or inadequately treated extrapyramidal signs and symptoms (EPS). Other important considerations in the differential diagnosis include central anticholinergic toxicity, heat stroke, malignant hyperthermia, drug fever and primary central nervous system (CNS) pathology. The management of NMS should include 1) immediate discontinuation of metoclopramide and other drugs not essential to concurrent therapy, 2) intensive symptomatic treatment and medical monitoring, and 3) treatment of any concomitant serious medical problems for which specific treatments are available. Bromocriptine and dantrolene sodium have been used in treatment of NMS, but their effectiveness have not been established (see ADVERSE REACTIONS). PRECAUTIONS General In one study in hypertensive patients, intravenously administered metoclopramide was shown to release catecholamines; hence, caution should be exercised when metoclopramide is used in patients with hypertension. Because metoclopramide produces a transient increase in plasma aldosterone, certain patients, especially those with cirrhosis or congestive heart failure, may be at risk of developing fluid retention and volume overload. If these side effects occur at any time during metoclopramide therapy, the drug should be discontinued. Adverse reactions, especially those involving the nervous system, may occur after stopping the use of reglan®. A small number of patients may experience a withdrawal period after stopping reglan® that could include dizziness, nervousness, and/or headaches. Information for Patients The use of reglan® is recommended for adults only. Metoclopramide may impair the mental and/or physical abilities required for the performance of hazardous tasks such as operating machinery or driving a motor vehicle. The ambulatory patient should be cautioned accordingly. For additional information, patients should be instructed to see the Medication Guide for reglan® tablets. Drug Interactions The effects of metoclopramide on gastrointestinal motility are antagonized by anticholinergic drugs and narcotic analgesics. Additive sedative effects can occur when metoclopramide is given with alcohol, sedatives, hypnotics, narcotics, or tranquilizers. The finding that metoclopramide releases catecholamines in patients with essential hypertension suggests that it should be used cautiously, if at all, in patients receiving monoamine oxidase inhibitors. Absorption of drugs from the stomach may be diminished (e.g., digoxin) by metoclopramide, whereas the rate and/or extent of absorption of drugs from the small bowel may be increased (e.g., acetaminophen, tetracycline, levodopa, ethanol, cyclosporine). REGLAN® - Package Insert Page 6 of 12 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda Gastroparesis (gastric stasis) may be responsible for poor diabetic control in some patients. Exogenously administered insulin may begin to act before food has left the stomach and lead to hypoglycemia. Because the action of metoclopramide will influence the delivery of food to the intestines and thus the rate of absorption, insulin dosage or timing of dosage may require adjustment. Carcinogenesis, Mutagenesis, Impairment of Fertility A 77-week study was conducted in rats with oral doses up to about 40 times the maximum recommended human daily dose. Metoclopramide elevates prolactin levels and the elevation persists during chronic administration. Tissue culture experiments indicate that approximately one-third of human breast cancers are prolactin-dependent in vitro, a factor of potential importance if the prescription of metoclopramide is contemplated in a patient with previously detected breast cancer. Although disturbances such as galactorrhea, amenorrhea, gynecomastia, and impotence have been reported with prolactin-elevating drugs, the clinical significance of elevated serum prolactin levels is unknown for most patients. An increase in mammary neoplasms has been found in rodents after chronic administration of prolactin-stimulating neuroleptic drugs and metoclopramide. Neither clinical studies nor epidemiologic studies conducted to date, however, have shown an association between chronic administration of these drugs and mammary tumorigenesis; the available evidence is too limited to be conclusive at this time. An Ames mutagenicity test performed on metoclopramide was negative. Pregnancy Category B Reproduction studies performed in rats, mice and rabbits by the I.V., I.M., S.C., and oral routes at maximum levels ranging from 12 to 250 times the human dose have demonstrated no impairment of fertility or significant harm to the fetus due to metoclopramide. There are, however, no adequate and well-controlled studies in pregnant women. Because animal reproduction studies are not always predictive of human response, this drug should be used during pregnancy only if clearly needed. Nursing Mothers Metoclopramide is excreted in human milk. Caution should be exercised when metoclopramide is administered to a nursing mother. Pediatric Use Safety and effectiveness in pediatric patients have not been established (see OVERDOSAGE). Care should be exercised in administering metoclopramide to neonates since prolonged clearance may produce excessive serum concentrations (see CLINICAL PHARMACOLOGY - Pharmacokinetics). In addition, neonates have reduced levels of NADH-cytochrome b5 reductase which, in combination with the aforementioned pharmacokinetic factors, make neonates more susceptible to methemoglobinemia (see OVERDOSAGE). The safety profile of metoclopramide in adults cannot be extrapolated to pediatric patients. Dystonias and other extrapyramidal reactions associated with metoclopramide REGLAN® - Package Insert Page 7 of 12 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda are more common in the pediatric population than in adults. (See WARNINGS and ADVERSE REACTIONS - Extrapyramidal Reactions.) Geriatric Use Clinical studies of reglan® did not include sufficient numbers of subjects aged 65 and over to determine whether elderly subjects respond differently from younger subjects. The risk of developing parkinsonian-like side effects increases with ascending dose. Geriatric patients should receive the lowest dose of reglan® that is effective. If parkinsonian-like symptoms develop in a geriatric patient receiving reglan®, reglan® should generally be discontinued before initiating any specific anti-parkinsonian agents (see WARNINGS and DOSAGE AND ADMINISTRATION – For the Relief of Symptomatic Gastroesophageal Reflux). The elderly may be at greater risk for tardive dyskinesia (see WARNINGS – Tardive Dyskinesia). Sedation has been reported in reglan® users. Sedation may cause confusion and manifest as over-sedation in the elderly (see CLINICAL PHARMACOLOGY, PRECAUTIONS – Information for Patients and ADVERSE REACTIONS – CNS Effects). reglan® is known to be substantially excreted by the kidney, and the risk of toxic reactions to this drug may be greater in patients with impaired renal function (see DOSAGE AND ADMINISTRATION – USE IN PATIENTS WITH RENAL OR HEPATIC IMPAIRMENT). For these reasons, dose selection for an elderly patient should be cautious, usually starting at the low end of the dosing range, reflecting the greater frequency of decreased renal function, concomitant disease, or other drug therapy in the elderly (see DOSAGE AND ADMINISTRATION – For the Relief of Symptomatic Gastroesophageal Reflux and USE IN PATIENTS WITH RENAL OR HEPATIC IMPAIRMENT). Other Special Populations Patients with NADH-cytochrome b5 reductase deficiency are at an increased risk of developing methemoglobinemia and/or sulfhemoglobinemia when metoclopramide is administered. In patients with G6PD deficiency who experience metoclopramide- induced methemoglobinemia, methylene blue treatment is not recommended (see OVERDOSAGE). ADVERSE REACTIONS In general, the incidence of adverse reactions correlates with the dose and duration of metoclopramide administration. The following reactions have been reported, although in most instances, data do not permit an estimate of frequency: CNS Effects Restlessness, drowsiness, fatigue, and lassitude occur in approximately 10% of patients receiving the most commonly prescribed dosage of 10 mg q.i.d. (see PRECAUTIONS). Insomnia, headache, confusion, dizziness, or mental depression with suicidal ideation REGLAN® - Package Insert Page 8 of 12 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda (see WARNINGS) occur less frequently. The incidence of drowsiness is greater at higher doses. There are isolated reports of convulsive seizures without clearcut relationship to metoclopramide. Rarely, hallucinations have been reported. Extrapyramidal Reactions (EPS) Acute dystonic reactions, the most common type of EPS associated with metoclopramide, occur in approximately 0.2% of patients (1 in 500) treated with 30 to 40 mg of metoclopramide per day. Symptoms include involuntary movements of limbs, facial grimacing, torticollis, oculogyric crisis, rhythmic protrusion of tongue, bulbar type of speech, trismus, opisthotonus (tetanus-like reactions), and, rarely, stridor and dyspnea possibly due to laryngospasm; ordinarily these symptoms are readily reversed by diphenhydramine (see WARNINGS). Parkinsonian-like symptoms may include bradykinesia, tremor, cogwheel rigidity, mask­ like facies (see WARNINGS). Tardive dyskinesia most frequently is characterized by involuntary movements of the tongue, face, mouth, or jaw, and sometimes by involuntary movements of the trunk and/or extremities; movements may be choreoathetotic in appearance (see WARNINGS). Motor restlessness (akathisia) may consist of feelings of anxiety, agitation, jitteriness, and insomnia, as well as inability to sit still, pacing, foot tapping. These symptoms may disappear spontaneously or respond to a reduction in dosage. Neuroleptic Malignant Syndrome Rare occurrences of neuroleptic malignant syndrome (NMS) have been reported. This potentially fatal syndrome is comprised of the symptom complex of hyperthermia, altered consciousness, muscular rigidity, and autonomic dysfunction (see WARNINGS). Endocrine Disturbances Galactorrhea, amenorrhea, gynecomastia, impotence secondary to hyperprolactinemia (see PRECAUTIONS). Fluid retention secondary to transient elevation of aldosterone (see CLINICAL PHARMACOLOGY). Cardiovascular Hypotension, hypertension, supraventricular tachycardia, bradycardia, fluid retention, acute congestive heart failure and possible AV block (see CONTRAINDICATIONS and PRECAUTIONS). Gastrointestinal Nausea and bowel disturbances, primarily diarrhea. Hepatic Rarely, cases of hepatotoxicity, characterized by such findings as jaundice and altered liver function tests, when metoclopramide was administered with other drugs with known hepatotoxic potential. Renal Urinary frequency and incontinence. Hematologic A few cases of neutropenia, leukopenia, or agranulocytosis, generally without clearcut REGLAN® - Package Insert Page 9 of 12 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda relationship to metoclopramide. Methemoglobinemia, in adults and especially with overdosage in neonates (see OVERDOSAGE). Sulfhemoglobinemia in adults. Allergic Reactions A few cases of rash, urticaria, or bronchospasm, especially in patients with a history of asthma. Rarely, angioneurotic edema, including glossal or laryngeal edema. Miscellaneous Visual disturbances. Porphyria. OVERDOSAGE Symptoms of overdosage may include drowsiness, disorientation and extrapyramidal reactions. Anticholinergic or antiparkinson drugs or antihistamines with anticholinergic properties may be helpful in controlling the extrapyramidal reactions. Symptoms are self-limiting and usually disappear within 24 hours. Hemodialysis removes relatively little metoclopramide, probably because of the small amount of the drug in blood relative to tissues. Similarly, continuous ambulatory peritoneal dialysis does not remove significant amounts of drug. It is unlikely that dosage would need to be adjusted to compensate for losses through dialysis. Dialysis is not likely to be an effective method of drug removal in overdose situations. Unintentional overdose due to misadministration has been reported in infants and children with the use of metoclopramide oral solution. While there was no consistent pattern to the reports associated with these overdoses, events included seizures, extrapyramidal reactions, and lethargy. Methemoglobinemia has occurred in premature and full-term neonates who were given overdoses of metoclopramide (1 to 4 mg/kg/day orally, intramuscularly or intravenously for 1 to 3 or more days). Methemoglobinemia can be reversed by the intravenous administration of methylene blue. However, methylene blue may cause hemolytic anemia in patients with G6PD deficiency, which may be fatal (see PRECAUTIONS – Other Special Populations). DOSAGE AND ADMINISTRATION Therapy with reglan® tablets should not exceed 12 weeks in duration. For the Relief of Symptomatic Gastroesophageal Reflux Administer from 10 mg to 15 mg reglan® (metoclopramide hydrochloride, USP) orally up to q.i.d. 30 minutes before each meal and at bedtime, depending upon symptoms being treated and clinical response (see CLINICAL PHARMACOLOGY and INDICATIONS AND USAGE). If symptoms occur only intermittently or at specific times of the day, use of metoclopramide in single doses up to 20 mg prior to the provoking situation may be preferred rather than continuous treatment. Occasionally, patients (such as elderly patients) who are more sensitive to the therapeutic or adverse effects of metoclopramide will require only 5 mg per dose. REGLAN® - Package Insert Page 10 of 12 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda Experience with esophageal erosions and ulcerations is limited, but healing has thus far been documented in one controlled trial using q.i.d. therapy at 15 mg/dose, and this regimen should be used when lesions are present, so long as it is tolerated (see ADVERSE REACTIONS). Because of the poor correlation between symptoms and endoscopic appearance of the esophagus, therapy directed at esophageal lesions is best guided by endoscopic evaluation. Therapy longer than 12 weeks has not been evaluated and cannot be recommended. For the Relief of Symptoms Associated with Diabetic Gastroparesis (Diabetic Gastric Stasis) Administer 10 mg of metoclopramide 30 minutes before each meal and at bedtime for two to eight weeks, depending upon response and the likelihood of continued well-being upon drug discontinuation. The initial route of administration should be determined by the severity of the presenting symptoms. If only the earliest manifestations of diabetic gastric stasis are present, oral administration of reglan® may be initiated. However, if severe symptoms are present, therapy should begin with metoclopramide injection (consult labeling of the injection prior to initiating parenteral administration). Administration of metoclopramide injection up to 10 days may be required before symptoms subside, at which time oral administration may be instituted. Since diabetic gastric stasis is frequently recurrent, reglan® therapy should be reinstituted at the earliest manifestation. USE IN PATIENTS WITH RENAL OR HEPATIC IMPAIRMENT Since metoclopramide is excreted principally through the kidneys, in those patients whose creatinine clearance is below 40 mL/min, therapy should be initiated at approximately one-half the recommended dosage. Depending upon clinical efficacy and safety considerations, the dosage may be increased or decreased as appropriate. See OVERDOSAGE section for information regarding dialysis. Metoclopramide undergoes minimal hepatic metabolism, except for simple conjugation. Its safe use has been described in patients with advanced liver disease whose renal function was normal.

There may be new information. If you take another product that contains metoclopramide (such as REGLAN injection, REGLAN ODT, or metoclopramide oral syrup), you should read the Medication Guide that comes with that product. Some of the information may be different. This Medication Guide does not take the place of talking with your doctor about your medical condition or your treatment. What is the most important information I should know about REGLAN? REGLAN can cause serious side effects, including: Abnormal muscle movements called tardive dyskinesia (TD). These movements happen mostly in the face muscles. You can not control these movements. They may not go away even after stopping REGLAN. There is no treatment for TD, but symptoms may lessen or go away over time after you stop taking REGLAN. Your chances for getting TD go up: • the longer you take REGLAN and the more REGLAN you take. You should not take REGLAN for more than 12 weeks. • if you are older, especially if you are a woman • if you have diabetes It is not possible for your doctor to know if you will get TD if you take REGLAN. Call your doctor right away if you get movements you can not stop or control, such as: • lip smacking, chewing, or puckering up your mouth • frowning or scowling • sticking out your tongue • blinking and moving your eyes • shaking of your arms and legs See the section “What are the possible side effects of REGLAN?” for more information about side effects. What is REGLAN? REGLAN is a prescription medicine used: • in adults for 4 to 12 weeks to relieve heartburn symptoms with gastroesophageal reflux disease (GERD) when certain other treatments do not work. REGLAN relieves daytime heartburn and heartburn after meals. It also helps ulcers in the esophagus to heal. This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda   • to relieve symptoms of slow stomach emptying in people with diabetes. REGLAN helps treat symptoms such as nausea, vomiting, heartburn, feeling full long after a meal, and loss of appetite. Not all these symptoms get better at the same time. It is not known if REGLAN is safe and works in children. Who should not take REGLAN? Do not take REGLAN if you: • have stomach or intestine problems that could get worse with REGLAN, such as bleeding, blockage or a tear in the stomach or bowel wall • have an adrenal gland tumor called a pheochromocytoma • are allergic to REGLAN or anything in it. See the end of this Medication Guide for a list of ingredients in REGLAN. • take medicines that can cause uncontrolled movements, such as medicines for mental illness • have seizures What should I tell my doctor before taking REGLAN? Tell your doctor about all your medical conditions, including if you have: • depression • Parkinson’s disease • high blood pressure • kidney problems. Your doctor may start with a lower dose. • liver problems or heart failure. REGLAN may cause your body to hold fluids. • diabetes. Your dose of insulin may need to be changed. • breast cancer • you are pregnant or plan to become pregnant. It is not known if REGLAN will harm your unborn baby. • you are breast-feeding. REGLAN can pass into breast milk and may harm your baby. Talk with your doctor about the best way to feed your baby if you take REGLAN. Tell your doctor about all the medicines you take, including prescription and non­ prescription medicines, vitamins, and herbal supplements. REGLAN and some other medicines may interact with each other and may not work as well, or cause possible side effects. Do not start any new medicines while taking REGLAN until you talk with your doctor. Especially tell your doctor if you take: • another medicine that contains metoclopramide, such as REGLAN ODT, or metoclopramide oral syrup • a blood pressure medicine • a medicine for depression, especially an Monoamine Oxidase Inhibitor (MAOI) • insulin • a medicine that can make you sleepy, such an anti-anxiety medicine, sleep medicines, and narcotics.

REGLAN may cause sleepiness. What are the possible side effects of REGLAN? Reglan can cause serious side effects, including: • Abnormal muscle movements. See “What is the most important information I need to about know REGLAN?” • Uncontrolled spasms of your face and neck muscles, or muscles of your body, arms, and legs (dystonia). These muscle spasms can cause abnormal movements and body positions. These spasms usually start within the first 2 days of treatment. These spasms happen more often in children and adults under age 30. • Depression, thoughts about suicide, and suicide. Some people who take REGLAN become depressed. You may have thoughts about hurting or killing yourself. Some people who take Reglan have ended their own lives (suicide). • Neuroleptic Malignant Syndrome (NMS). NMS is a very rare but very serious condition that can happen with Reglan. NMS can cause death and must be treated in a hospital. Symptoms of NMS include: high fever, stiff muscles, problems thinking, very fast or uneven heartbeat, and increased sweating. • Parkinsonism. Symptoms include slight shaking, body stiffness, trouble moving or keeping your balance. If you already have Parkinson’s disease, your symptoms may become worse while you are receiving REGLAN. Call your doctor and get medical help right away if you: • feel depressed or have thoughts about hurting or killing yourself • have high fever, stiff muscles, problems thinking, very fast or uneven heartbeat, and increased sweating • have muscle movements you cannot stop or control • have muscle movements that are new or unusual This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda   Common side effects of Reglan include: • feeling restless, sleepy, tired, dizzy, or exhausted • headache • confusion • trouble sleeping You may have more side effects the longer you take REGLAN and the more REGLAN you take. You may still have side effects after stopping REGLAN. You may have symptoms from stopping (withdrawal) REGLAN such as headaches, and feeling dizzy or nervous.

Metoclopramide therapy should be discontinued in patients who develop signs or symptoms of tardive dyskinesia. There is no known treatment for tardive dyskinesia. In some patients, symptoms may lessen or resolve after metoclopramide treatment is stopped. Treatment with metoclopramide for longer than 12 weeks should be avoided in all but rare cases where therapeutic benefit is thought to outweigh the risk of developing tardive dyskinesia. See WARNINGS DESCRIPTION REGLAN ODT™ (metoclopramide orally disintegrating tablets) is an orally administered formulation of metoclopramide which disintegrates on the tongue. Metoclopramide hydrochloride is a white crystalline, odorless substance, freely soluble in water. Chemically, it is 4-amino-5-chloro-N-[2-(diethylamino)ethyl]-2-methoxy benzamide monohydrochloride monohydrate. Its molecular formula is C14H22ClN3O2•HCl•H2O. Its molecular weight is 354.3. Structural Formula Each orally disintegrating tablet contains either 5 mg or 10 mg of metoclopramide base (as the monohydrochloride monohydrate) and the following inactive ingredients: aspartame, colloidal silicon dioxide, crospovidone, magnesium stearate, mannitol, aminoalkyl methacrylate copolymer, microcrystalline cellulose, natural and artificial orange flavor and povidone.

For current labeling information, please visit https://www.fda.gov/drugsatfda CLINICAL PHARMACOLOGY Metoclopramide stimulates motility of the upper gastrointestinal tract without stimulating gastric, biliary, or pancreatic secretions. Its mode of action is unclear. It seems to sensitize tissues to the action of acetylcholine. The effect of metoclopramide on motility is not dependent on intact vagal innervation, but it can be abolished by anticholinergic drugs. Metoclopramide increases the tone and amplitude of gastric (especially antral) contractions, relaxes the pyloric sphincter and the duodenal bulb, and increases peristalsis of the duodenum and jejunum resulting in accelerated gastric emptying and intestinal transit. It increases the resting tone of the lower esophageal sphincter. It has little, if any, effect on the motility of the colon or gallbladder. In patients with gastroesophageal reflux and low LESP (lower esophageal sphincter pressure), single oral doses of metoclopramide produce dose-related increases in LESP. Effects begin at about 5 mg and increase through 20 mg (the largest dose tested). The increase in LESP from a 5 mg dose lasts about 45 minutes and that of 20 mg lasts between 2 and 3 hours. Increased rate of stomach emptying has been observed with single oral doses of 10 mg. The antiemetic properties of metoclopramide appear to be a result of its antagonism of central and peripheral dopamine receptors. Dopamine produces nausea and vomiting by stimulation of the medullary chemoreceptor trigger zone (CTZ), and metoclopramide blocks stimulation of the CTZ by agents like l-dopa or apomorphine which are known to increase dopamine levels or to possess dopamine-like effects. Metoclopramide also abolishes the slowing of gastric emptying caused by apomorphine. Like the phenothiazines and related drugs, which are also dopamine antagonists, metoclopramide produces sedation and may produce extrapyramidal reactions, although these are comparatively rare (see WARNINGS). Metoclopramide inhibits the central and peripheral effects of apomorphine, induces release of prolactin and causes a transient increase in circulating aldosterone levels, which may be associated with transient fluid retention. The onset of pharmacological action of metoclopramide is 1 to 3 minutes following an intravenous dose, 10 to 15 minutes following intramuscular administration, and 30 to 60 minutes following an oral dose; pharmacological effects persist for 1 to 2 hours. Pharmacokinetics Metoclopramide is rapidly and well absorbed. Relative to an intravenous dose of 20 mg, the absolute oral bioavailability of metoclopramide is 80% ± 15.5% as demonstrated in a crossover study of 18 subjects. Peak plasma concentrations occur at about 1 to 2 hr after a single oral dose. Similar time to peak is observed after individual doses at steady state. In a single dose study of 12 subjects, the area under the drug concentration-time curve increases linearly with doses from 20 to 100 mg. Peak concentrations increase linearly with dose; time to peak concentrations remains the same; whole body clearance is unchanged; and the elimination rate remains the same. The mean elimination half-life of metoclopramide is approximately 7 hr REGLAN ODT™ - Package Insert Page 2 of 14 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda after administration of REGLAN ODT™. Linear kinetic processes adequately describe the absorption and elimination of metoclopramide. Approximately 85% of the radioactivity of an orally administered dose appears in the urine within 72 hr. Of the 85% eliminated in the urine, about half is present as free or conjugated metoclopramide. The drug is not extensively bound to plasma proteins (about 30%). The whole body volume of distribution is high (about 3.5 L/kg) which suggests extensive distribution of drug to the tissues. Renal impairment affects the clearance of metoclopramide. In a study with patients with varying degrees of renal impairment, a reduction in creatinine clearance was correlated with a reduction in plasma clearance, renal clearance, non-renal clearance, and increase in elimination half-life. The kinetics of metoclopramide in the presence of renal impairment remained linear however. The reduction in clearance as a result of renal impairment suggests that adjustment downward of maintenance dosage should be done to avoid drug accumulation. Adult Pharmacokinetic Data Parameter Value Vd (L/kg) ~ 3.5 Plasma Protein Binding ~ 30% t½ (hr) ~ 7 Oral Bioavailability 80% ± 15.5% In pediatric patients, the pharmacodynamics of metoclopramide following oral and intravenous administration are highly variable and a concentration-effect relationship has not been established. There are insufficient reliable data to conclude whether the pharmacokinetics of metoclopramide in adults and the pediatric population are similar. Although there are insufficient data to support the efficacy of metoclopramide in pediatric patients with symptomatic gastroesophageal reflux (GER) or cancer chemotherapy-related nausea and vomiting, its pharmacokinetics have been studied in these patient populations. In an open-label study, six pediatric patients (age range, 3.5 weeks to 5.4 months) with GER received metoclopramide 0.15 mg/kg oral solution every 6 hours for 10 doses. The mean peak plasma concentration of metoclopramide after the tenth dose was 2-fold (56.8 μg/L) higher compared to that observed after the first dose (29 μg/L) indicating drug accumulation with repeated dosing. After the tenth dose, the mean time to reach peak concentrations (2.2 hr), half- life (4.1 hr), clearance (0.67 L/h/kg), and volume of distribution (4.4 L/kg) of metoclopramide were similar to those observed after the first dose. In the youngest patient (age, 3.5 weeks), REGLAN ODT™ - Package Insert Page 3 of 14 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda metoclopramide half-life after the first and the tenth dose (23.1 and 10.3 hr, respectively) was significantly longer compared to other infants due to reduced clearance. This may be attributed to immature hepatic and renal systems at birth. Single intravenous doses of metoclopramide 0.22 to 0.46 mg/kg (mean, 0.35 mg/kg) were administered over 5 minutes to 9 pediatric cancer patients receiving chemotherapy (mean age, 11.7 years; range, 7 to 14 yr) for prophylaxis of cytotoxic-induced vomiting. The metoclopramide plasma concentrations extrapolated to time zero ranged from 65 to 395 μg/L (mean, 152 μg/L). The mean elimination half-life, clearance, and volume of distribution of metoclopramide were 4.4 hr (range, 1.7 to 8.3 hr), 0.56 L/h/kg (range, 0.12 to 1.20 L/h/kg), and 3.0 L/kg (range, 1.0 to 4.8 L/kg), respectively. In another study, nine pediatric cancer patients (age range, 1 to 9 yr) received 4 to 5 intravenous infusions (over 30 minutes) of metoclopramide at a dose of 2 mg/kg to control emesis. After the last dose, the peak serum concentrations of metoclopramide ranged from 1060 to 5680 μg/L. The mean elimination half-life, clearance, and volume of distribution of metoclopramide were 4.5 hr (range, 2.0 to 12.5 hr), 0.37 L/h/kg (range, 0.10 to 1.24 L/h/kg), and 1.93 L/kg (range, 0.95 to 5.50 L/kg), respectively. INDICATIONS AND USAGE The use of REGLAN ODT™ is recommended for adults only. Therapy should not exceed 12 weeks in duration. Symptomatic Gastroesophageal Reflux REGLAN ODT™ is indicated as short-term (4 to 12 weeks) therapy for adults with symptomatic, documented gastroesophageal reflux who fail to respond to conventional therapy. The principal effect of metoclopramide is on symptoms of postprandial and daytime heartburn with less observed effect on nocturnal symptoms. If symptoms are confined to particular situations, such as following the evening meal, use of metoclopramide as single doses prior to the provocative situation should be considered, rather than using the drug throughout the day. Healing of esophageal ulcers and erosions has been endoscopically demonstrated at the end of a 12-week trial using doses of 15 mg four times daily. As there is no documented correlation between symptoms and healing of esophageal lesions, patients with documented lesions should be monitored endoscopically. Diabetic Gastroparesis (Diabetic Gastric Stasis) REGLAN ODT™ is indicated for the relief of symptoms associated with acute and recurrent diabetic gastric stasis. The usual manifestations of delayed gastric emptying (e.g., nausea, vomiting, heartburn, persistent fullness after meals, and anorexia) appear to respond to metoclopramide within different time intervals. Significant relief of nausea occurs early and continues to improve over a three-week period. Relief of vomiting and anorexia may precede the relief of abdominal fullness by one week or more. REGLAN ODT™ - Package Insert Page 4 of 14 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda CONTRAINDICATIONS Metoclopramide should not be used whenever stimulation of gastrointestinal motility might be dangerous, e.g., in the presence of gastrointestinal hemorrhage, mechanical obstruction, or perforation. Metoclopramide is contraindicated in patients with pheochromocytoma because the drug may cause a hypertensive crisis, probably due to release of catecholamines from the tumor. Such hypertensive crises may be controlled by phentolamine. Metoclopramide is contraindicated in patients with known sensitivity or intolerance to the drug. Metoclopramide should not be used in epileptics or patients receiving other drugs which are likely to cause extrapyramidal reactions, since the frequency and severity of seizures or extrapyramidal reactions may be increased. WARNINGS Mental depression has occurred in patients with and without prior history of depression. Symptoms have ranged from mild to severe and have included suicidal ideation and suicide. Metoclopramide should be given to patients with a prior history of depression only if the expected benefits outweigh the potential risks. Extrapyramidal symptoms, manifested primarily as acute dystonic reactions, occur in approximately 1 in 500 patients treated with the usual adult dosages of 30 to 40 mg/day of metoclopramide. These usually are seen during the first 24 to 48 hours of treatment with metoclopramide, occur more frequently in pediatric patients and adult patients less than 30 years of age and are even more frequent at higher doses. These symptoms may include involuntary movements of limbs and facial grimacing, torticollis, oculogyric crisis, rhythmic protrusion of tongue, bulbar type of speech, trismus, or dystonic reactions resembling tetanus. Rarely, dystonic reactions may present as stridor and dyspnea, possibly due to laryngospasm. If these symptoms should occur, inject 50 mg diphenhydramine hydrochloride intramuscularly, and they usually will subside. Benztropine mesylate, 1 to 2 mg intramuscularly, may also be used to reverse these reactions. Parkinsonian-like symptoms have occurred, more commonly within the first 6 months after beginning treatment with metoclopramide, but occasionally after longer periods. These symptoms generally subside within 2 to 3 months following discontinuance of metoclopramide. Patients with preexisting Parkinson’s disease should be given metoclopramide cautiously, if at all, since such patients may experience exacerbation of parkinsonian symptoms when taking metoclopramide. Tardive Dyskinesia (see Boxed Warnings) Treatment with metoclopramide can cause tardive dyskinesia (TD), a potentially irreversible and disfiguring disorder characterized by involuntary movements of the face, tongue, or extremities. REGLAN ODT™ - Package Insert Page 5 of 14 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda Although the risk of TD with metoclopramide has not been extensively studied, one published study reported a TD prevalence of 20% among patients treated for at least 12 weeks. Treatment with metoclopramide for longer than 12 weeks should be avoided in all but rare cases where therapeutic benefit is thought to outweigh the risk of developing TD. Although the risk of developing TD in the general population may be increased among the elderly, women, and diabetics, it is not possible to predict which patients will develop metoclopramide-induced TD. Both the risk of developing TD and the likelihood that TD will become irreversible increase with duration of treatment and total cumulative dose. Metoclopramide should be discontinued in patients who develop signs or symptoms of TD. There is no known effective treatment for established cases of TD, although in some patients, TD may remit, partially or completely, within several weeks to months after metoclopramide is withdrawn. Metoclopramide itself may suppress, or partially suppress, the signs of TD, thereby masking the underlying disease process. The effect of this symptomatic suppression upon the long-term course of TD is unknown. Therefore, metoclopramide should not be used for the symptomatic control of TD. Neuroleptic Malignant Syndrome (NMS) There have been rare reports of an uncommon but potentially fatal symptom complex sometimes referred to as Neuroleptic Malignant Syndrome (NMS) associated with metoclopramide. Clinical manifestations of NMS include hyperthermia, muscle rigidity, altered consciousness, and evidence of autonomic instability (irregular pulse or blood pressure, tachycardia, diaphoresis and cardiac arrhythmias). The diagnostic evaluation of patients with this syndrome is complicated. In arriving at a diagnosis, it is important to identify cases where the clinical presentation includes both serious medical illness (e.g., pneumonia, systemic infection, etc.) and untreated or inadequately treated extrapyramidal signs and symptoms (EPS). Other important considerations in the differential diagnosis include central anticholinergic toxicity, heat stroke, malignant hyperthermia, drug fever and primary central nervous system (CNS) pathology. The management of NMS should include 1) immediate discontinuation of metoclopramide and other drugs not essential to concurrent therapy, 2) intensive symptomatic treatment and medical monitoring, and 3) treatment of any concomitant serious medical problems for which specific treatments are available. Bromocriptine and dantrolene sodium have been used in treatment of NMS, but their effectiveness have not been established (see ADVERSE REACTIONS). PRECAUTIONS General In one study in hypertensive patients, intravenously administered metoclopramide was shown to release catecholamines; hence, caution should be exercised when metoclopramide is used in patients with hypertension. REGLAN ODT™ - Package Insert Page 6 of 14 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda Because metoclopramide produces a transient increase in plasma aldosterone, certain patients, especially those with cirrhosis or congestive heart failure, may be at risk of developing fluid retention and volume overload. If these side effects occur at any time during metoclopramide therapy, the drug should be discontinued. Adverse reactions, especially those involving the nervous system, may occur after stopping the use of REGLAN ODT™. A small number of patients may experience a withdrawal period after stopping REGLAN ODT™ that could include dizziness, nervousness, and/or headaches. Information for Patients Patients should be instructed not to remove REGLAN ODT™ orally disintegrating tablets from the bottle until just prior to dosing. With dry hands, the tablet should be removed from the bottle and immediately placed on the tongue to disintegrate and be swallowed with the saliva. The tablet typically disintegrates in about one and one-half minutes. Administration with liquid is not necessary. The use of REGLAN ODT™ orally disintegrating tablets is recommended for adults only. Metoclopramide may impair the mental and/or physical abilities required for the performance of hazardous tasks such as operating machinery or driving a motor vehicle. The ambulatory patient should be cautioned accordingly. For additional information, patients should be instructed to see the Medication Guide for REGLAN ODT™. Phenylketonurics Phenylketonuric patients should be informed that REGLAN ODT™ contains phenylalanine 4.2 mg per 5 mg orally disintegrating tablet and 8.3 mg per 10 mg orally disintegrating tablet. Drug Interactions The effects of metoclopramide on gastrointestinal motility are antagonized by anticholinergic drugs and narcotic analgesics. Additive sedative effects can occur when metoclopramide is given with alcohol, sedatives, hypnotics, narcotics, or tranquilizers. The finding that metoclopramide releases catecholamines in patients with essential hypertension suggests that it should be used cautiously, if at all, in patients receiving monoamine oxidase inhibitors. Absorption of drugs from the stomach may be diminished (e.g., digoxin) by metoclopramide, whereas the rate and/or extent of absorption of drugs from the small bowel may be increased (e.g., acetaminophen, tetracycline, levodopa, ethanol, cyclosporine). Gastroparesis (gastric stasis) may be responsible for poor diabetic control in some patients. Exogenously administered insulin may begin to act before food has left the stomach and lead to hypoglycemia. Because the action of metoclopramide will influence the delivery of food to the REGLAN ODT™ - Package Insert Page 7 of 14 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda intestines and thus the rate of absorption, insulin dosage or timing of dosage may require adjustment. Carcinogenesis, Mutagenesis, Impairment of Fertility A 77-week study was conducted in rats with oral doses of metoclopramide up to 40 mg/kg/day (about 5 times the maximum recommended human dose on surface area basis). Metoclopramide elevates prolactin levels and the elevation persists during chronic administration. Tissue culture experiments indicate that approximately one-third of human breast cancers are prolactin- dependent in vitro, a factor of potential importance if the prescription of metoclopramide is contemplated in a patient with previously detected breast cancer. Although disturbances such as galactorrhea, amenorrhea, gynecomastia, and impotence have been reported with prolactin- elevating drugs, the clinical significance of elevated serum prolactin levels is unknown for most patients. An increase in mammary neoplasms has been found in rodents after chronic administration of prolactin-stimulating neuroleptic drugs and metoclopramide. Neither clinical studies nor epidemiologic studies conducted to date, however, have shown an association between chronic administration of these drugs and mammary tumorigenesis; the available evidence is too limited to be conclusive at this time. In a rat model for assessing the tumor promotion potential, a two-week oral treatment with metoclopramide at a dose of 260 mg/kg/day (about 35 times the maximum recommended human dose on surface area basis) enhanced the tumorigenic effect of N-nitrosodiethylamine. Metoclopramide was positive in the in vitro Chinese hamster lung cell/HGPRT forward mutation assay for mutagenic effects and the in vitro human lymphocyte chromosome aberration assay for clastogenic effects. It was negative in the in vitro Ames mutation assay, the in vitro unscheduled DNA synthesis (UDS) assay with rat and human hepatocytes and the in vivo rat micronucleus assay. Metoclopramide at intramuscular doses up to 20 mg/kg/day in male and female rats (about 3 times the maximum recommended human dose on surface area basis) was found to have no effect on fertility and reproductive performance. Pregnancy Teratogenic Effects: Pregnancy Category B Teratology studies have been performed in rats at oral doses up to 45 mg/kg/day (about 6 times the maximum recommended human dose on surface area basis), and in rabbits at oral doses up to 45 mg/kg/day (about 12 times the maximum recommended human dose on surface area basis) and have revealed no evidence of impaired fertility or harm to the fetus due to metoclopramide. There are, however, no adequate and well-controlled studies in pregnant women. Because animal reproduction studies are not always predictive of human response, this drug should be used during pregnancy only if clearly needed. Nursing Mothers Metoclopramide is excreted in human milk. Caution should be exercised when metoclopramide is administered to a nursing mother. Because of the potential for serious adverse reactions in nursing infants from metoclopramide and because of the potential for tumorigenicity and tumor promoting potential shown for metoclopramide in rats, a decision should be made whether to REGLAN ODT™ - Package Insert Page 8 of 14 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda discontinue nursing or to discontinue the drug, taking into account the importance of the drug to the mother. Pediatric Use Safety and effectiveness in pediatric patients have not been established (see OVERDOSAGE). Care should be exercised in administering metoclopramide to neonates since prolonged clearance may produce excessive serum concentrations (see CLINICAL PHARMACOLOGY— Pharmacokinetics). In addition, neonates have reduced levels of NADH-cytochrome b5 reductase which, in combination with the aforementioned pharmacokinetic factors, make neonates more susceptible to methemoglobinemia (see OVERDOSAGE). The safety profile of metoclopramide in adults cannot be extrapolated to pediatric patients. Dystonias and other extrapyramidal reactions associated with metoclopramide are more common in the pediatric population than in adults. (See WARNINGS and ADVERSE REACTIONS— Extrapyramidal Reactions.) Geriatric Use Clinical studies of metoclopramide did not include sufficient numbers of subjects aged 65 and over to determine whether elderly subjects respond differently from younger subjects. The risk of developing parkinsonian-like side effects increases with ascending dose. Geriatric patients should receive the lowest dose of REGLAN ODT™ that is effective. If parkinsonian- like symptoms develop in a geriatric patient receiving REGLAN ODT™, REGLAN ODT™ should generally be discontinued before initiating any specific anti-parkinsonian agents (see WARNINGS and DOSAGE AND ADMINISTRATION – For the Relief of Symptomatic Gastroesophageal Reflux). The elderly may be at greater risk for tardive dyskinesia (see WARNINGS – Tardive Dyskinesia). Sedation has been reported in metoclopramide users. Sedation may cause confusion and manifest as over-sedation in the elderly (see CLINICAL PHARMACOLOGY, PRECAUTIONS – Information for Patients and ADVERSE REACTIONS – CNS Effects). Metoclopramide is known to be substantially excreted by the kidney, and the risk of toxic reactions to this drug may be greater in patients with impaired renal function (see DOSAGE AND ADMINISTRATION – Use in Patients with Renal or Hepatic Impairment). For these reasons, dose selection for an elderly patient should be cautious, usually starting at the low end of the dosing range, reflecting the greater frequency of decreased renal function, concomitant disease, or other drug therapy in the elderly (see DOSAGE AND ADMINISTRATION – For the Relief of Symptomatic Gastroesophageal Reflux and Use in Patients with Renal or Hepatic Impairment). Other Special Populations Patients with NADH-cytochrome b5 reductase deficiency are at an increased risk of developing methemoglobinemia and/or sulfhemoglobinemia when metoclopramide is administered. In REGLAN ODT™ - Package Insert Page 9 of 14 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda patients with G6PD deficiency who experience metoclopramide-induced methemoglobinemia, methylene blue treatment is not recommended (see OVERDOSAGE). ADVERSE REACTIONS In general, the incidence of adverse reactions correlates with the dose and duration of metoclopramide administration. The following reactions have been reported, although in most instances, data do not permit an estimate of frequency: CNS Effects Restlessness, drowsiness, fatigue, and lassitude occur in approximately 10% of patients receiving the most commonly prescribed dosage of 10 mg four times daily. (see PRECAUTIONS). Insomnia, headache, confusion, dizziness, or mental depression with suicidal ideation (see WARNINGS) occur less frequently. The incidence of drowsiness is greater at higher doses. There are isolated reports of convulsive seizures without clear-cut relationship to metoclopramide. Rarely, hallucinations have been reported. Extrapyramidal Reactions (EPS) Acute dystonic reactions, the most common type of EPS associated with metoclopramide, occur in approximately 0.2% of patients (1 in 500) treated with 30 to 40 mg of metoclopramide per day. Symptoms include involuntary movements of limbs, facial grimacing, torticollis, oculogyric crisis, rhythmic protrusion of tongue, bulbar type of speech, trismus, opisthotonus (tetanus-like reactions), and, rarely, stridor and dyspnea possibly due to laryngospasm; ordinarily these symptoms are readily reversed by diphenhydramine (see WARNINGS). Parkinsonian-like symptoms may include bradykinesia, tremor, cogwheel rigidity, mask-like facies (see WARNINGS). Tardive dyskinesia most frequently is characterized by involuntary movements of the tongue, face, mouth, or jaw, and sometimes by involuntary movements of the trunk and/or extremities; movements may be choreoathetotic in appearance (see WARNINGS). Motor restlessness (akathisia) may consist of feelings of anxiety, agitation, jitteriness, and insomnia, as well as inability to sit still, pacing, foot tapping. These symptoms may disappear spontaneously or respond to a reduction in dosage. Neuroleptic Malignant Syndrome Rare occurrences of neuroleptic malignant syndrome (NMS) have been reported. This potentially fatal syndrome is comprised of the symptom complex of hyperthermia, altered consciousness, muscular rigidity, and autonomic dysfunction (see WARNINGS). Endocrine Disturbances Galactorrhea, amenorrhea, gynecomastia, impotence secondary to hyperprolactinemia (see PRECAUTIONS). Fluid retention secondary to transient elevation of aldosterone (see CLINICAL PHARMACOLOGY). Cardiovascular REGLAN ODT™ - Package Insert Page 10 of 14 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda Hypotension, hypertension, supraventricular tachycardia, bradycardia, fluid retention, acute congestive heart failure and possible AV block (see CONTRAINDICATIONS and PRECAUTIONS). Gastrointestinal Nausea and bowel disturbances, primarily diarrhea. Hepatic Rarely, cases of hepatotoxicity, characterized by such findings as jaundice and altered liver function tests, when metoclopramide was administered with other drugs with known hepatotoxic potential. Renal Urinary frequency and incontinence. Hematologic A few cases of neutropenia, leukopenia, or agranulocytosis, generally without clear-cut relationship to metoclopramide. Methemoglobinemia, in adults and especially with overdosage in neonates (see OVERDOSAGE). Sulfhemoglobinemia in adults. Allergic Reactions A few cases of rash, urticaria, or bronchospasm, especially in patients with a history of asthma. Rarely, angioneurotic edema, including glossal or laryngeal edema. Miscellaneous Visual disturbances. Porphyria. The adverse experience profile seen with REGLAN ODT™ orally disintegrating tablets in 21 healthy subjects, was similar to that seen with Reglan® Tablets. OVERDOSAGE Symptoms of overdosage may include drowsiness, disorientation and extrapyramidal reactions. Anticholinergic or antiparkinson drugs or antihistamines with anticholinergic properties may be helpful in controlling the extrapyramidal reactions. Symptoms are self-limiting and usually disappear within 24 hours. Hemodialysis removes relatively little metoclopramide, probably because of the small amount of the drug in blood relative to tissues. Similarly, continuous ambulatory peritoneal dialysis does not remove significant amounts of drug. It is unlikely that dosage would need to be adjusted to compensate for losses through dialysis. Dialysis is not likely to be an effective method of drug removal in overdose situations. Unintentional overdose due to misadministration has been reported in infants and children with the use of metoclopramide oral solution. While there was no consistent pattern to the reports associated with these overdoses, events included seizures, extrapyramidal reactions, and lethargy. REGLAN ODT™ - Package Insert Page 11 of 14 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda Methemoglobinemia has occurred in premature and full-term neonates who were given overdoses of metoclopramide (1 to 4 mg/kg/day orally, intramuscularly or intravenously for 1 to 3 or more days). Methemoglobinemia can be reversed by the intravenous administration of methylene blue. However, methylene blue may cause hemolytic anemia in patients with G6PD deficiency, which may be fatal (see PRECAUTIONS – Other Special Populations). DOSAGE AND ADMINISTRATION Therapy with REGLAN ODT™ should not exceed 12 weeks in duration. Instructions for Use/Handling REGLAN ODT™ Just prior to administration, remove the REGLAN ODT™ orally disintegrating tablet from the bottle with dry hands. The tablet should be removed from the bottle and immediately placed on the tongue, to disintegrate and be swallowed with the saliva. The tablet typically disintegrates in about one and one-half minutes. Administration with liquid is not necessary. For the Relief of Symptomatic Gastroesophageal Reflux Administer from 10 mg to 15 mg of REGLAN ODT™ orally up to four times daily, 30 minutes before each meal and at bedtime, depending upon symptoms being treated and clinical response (see CLINICAL PHARMACOLOGY and INDICATIONS AND USAGE). If symptoms occur only intermittently or at specific times of the day, use of metoclopramide in single doses up to 20 mg prior to the provoking situation may be preferred rather than continuous treatment. Occasionally, patients (such as elderly patients) who are more sensitive to the therapeutic or adverse effects of metoclopramide will require only 5 mg per dose. Experience with esophageal erosions and ulcerations is limited, but healing has thus far been documented in one controlled trial using four times daily therapy at 15 mg/dose, and this regimen should be used when lesions are present, so long as it is tolerated (see ADVERSE REACTIONS). Because of the poor correlation between symptoms and endoscopic appearance of the esophagus, therapy directed at esophageal lesions is best guided by endoscopic evaluation. Therapy longer than 12 weeks has not been evaluated and cannot be recommended. For the Relief of Symptoms Associated with Diabetic Gastroparesis (Diabetic Gastric Stasis) Administer 10 mg of REGLAN ODT™ 30 minutes before each meal and at bedtime for two to eight weeks, depending upon response and the likelihood of continued well-being upon drug discontinuation. The initial route of administration should be determined by the severity of the presenting symptoms. If only the earliest manifestations of diabetic gastric stasis are present, oral administration of REGLAN ODT™ may be initiated. However, if severe symptoms are present, therapy should begin with metoclopramide injection (consult labeling of the injection prior to initiating parenteral administration). REGLAN ODT™ - Package Insert Page 12 of 14 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda Administration of metoclopramide injection up to 10 days may be required before symptoms subside, at which time oral administration may be instituted. Since diabetic gastric stasis is frequently recurrent, REGLAN ODT™ therapy should be reinstituted at the earliest manifestation. Use in Patients with Renal or Hepatic Impairment Since metoclopramide is excreted principally through the kidneys, in those patients whose creatinine clearance is below 40 mL/min, therapy should be initiated at approximately one-half the recommended dosage. Depending upon clinical efficacy and safety considerations, the dosage may be increased or decreased as appropriate. See OVERDOSAGE section for information regarding dialysis. Metoclopramide undergoes minimal hepatic metabolism, except for simple conjugation. Its safe use has been described in patients with advanced liver disease whose renal function was normal.

There may be new information. If you take another product that contains metoclopramide (such as REGLAN tablets, REGLAN injection, or metoclopramide oral syrup), you should read the Medication Guide that comes with that product. Some of the information may be different. This Medication Guide does not take the place of talking with your doctor about your medical condition or your treatment. What is the most important information I should know about REGLAN ODT? REGLAN ODT can cause serious side effects, including: Abnormal muscle movements called tardive dyskinesia (TD). These movements happen mostly in the face muscles. You can not control these movements. They may not go away even after stopping REGLAN ODT. There is no treatment for TD, but symptoms may lessen or go away over time after you stop taking REGLAN ODT. Your chances for getting TD go up: • the longer you take REGLAN ODT and the more REGLAN ODT you take. You should not take REGLAN ODT for more than 12 weeks. • if you are older, especially if you are a woman • if you have diabetes. It is not possible for your doctor to know if you will get TD if you take REGLAN ODT. Call your doctor right away if you get movements you can not stop or control, such as: • lip smacking, chewing, or puckering up your mouth • frowning or scowling • sticking out your tongue • blinking and moving your eyes • shaking of your arms and legs See the section “What are the possible side effects of REGLAN ODT?” for more information about side effects. What is REGLAN ODT? REGLAN ODT is a prescription medicine used: • in adults for 4 to 12 weeks to relieve heartburn symptoms with gastroesophageal reflux disease (GERD) when certain other treatments do not work. REGLAN ODT relieves daytime heartburn and heartburn after meals. It also helps ulcers in the esophagus to heal. • to relieve symptoms of slow stomach emptying in people with diabetes. REGLAN ODT helps treat symptoms such as nausea, vomiting, heartburn, feeling full long after a meal, and loss of appetite. Not all these symptoms get better at the same time. It is not known if REGLAN ODT is safe and works in children. This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda   Who should not take REGLAN ODT?

reglan® tablets (metoclopramide tablets, USP) Rx Only WARNING: TARDIVE DYSKINESIA Treatment with metoclopramide can cause tardive dyskinesia, a serious movement disorder that is often irreversible. The risk of developing tardive dyskinesia increases with duration of treatment and total cumulative dose. Metoclopramide therapy should be discontinued in patients who develop signs or symptoms of tardive dyskinesia. There is no known treatment for tardive dyskinesia. In some patients, symptoms may lessen or resolve after metoclopramide treatment is stopped. Treatment with metoclopramide for longer than 12 weeks should be avoided in all but rare cases where therapeutic benefit is thought to outweigh the risk of developing tardive dyskinesia. See WARNINGS DESCRIPTION For oral administration, reglan® tablets (metoclopramide tablets, USP) 10 mg are white, scored, capsule-shaped tablets engraved “REGLAN” on one side and “ANI 10” on the opposite side. Each tablet contains: Metoclopramide base .................................................. 10 mg (as the monohydrochloride monohydrate) Inactive Ingredients Magnesium Stearate, Mannitol, Microcrystalline Cellulose, Stearic Acid. reglan® tablets (metoclopramide tablets, USP) 5 mg are green, elliptical-shaped tablets engraved “REGLAN” over “5” on one side and “ANI” on the opposite side. Each tablet contains: Metoclopramide base .................................................... 5 mg (as the monohydrochloride monohydrate) Inactive Ingredients Corn starch, D&C Yellow 10 Aluminum Lake, FD&C Blue 1 Aluminum Lake, Lactose, Microcrystalline Cellulose, Silicon Dioxide, Stearic Acid. Metoclopramide hydrochloride is a white crystalline, odorless substance, freely soluble in water. Chemically, it is 4-amino-5- chloro-N-[2-(diethylamino)ethyl]-2-methoxy Reference ID: 3018416 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda structural formula benzamide monohydrochloride monohydrate. Its molecular formula is C14H22ClN3O2•HCl•H2O. Its molecular weight is 354.3. CLINICAL PHARMACOLOGY Metoclopramide stimulates motility of the upper gastrointestinal tract without stimulating gastric, biliary, or pancreatic secretions. Its mode of action is unclear. It seems to sensitize tissues to the action of acetylcholine. The effect of metoclopramide on motility is not dependent on intact vagal innervation, but it can be abolished by anticholinergic drugs. Metoclopramide increases the tone and amplitude of gastric (especially antral) contractions, relaxes the pyloric sphincter and the duodenal bulb, and increases peristalsis of the duodenum and jejunum resulting in accelerated gastric emptying and intestinal transit. It increases the resting tone of the lower esophageal sphincter. It has little, if any, effect on the motility of the colon or gallbladder. In patients with gastroesophageal reflux and low LESP (lower esophageal sphincter pressure), single oral doses of metoclopramide produce dose-related increases in LESP. Effects begin at about 5 mg and increase through 20 mg (the largest dose tested). The increase in LESP from a 5 mg dose lasts about 45 minutes and that of 20 mg lasts between 2 and 3 hours. Increased rate of stomach emptying has been observed with single oral doses of 10 mg. The antiemetic properties of metoclopramide appear to be a result of its antagonism of central and peripheral dopamine receptors. Dopamine produces nausea and vomiting by stimulation of the medullary chemoreceptor trigger zone (CTZ), and metoclopramide blocks stimulation of the CTZ by agents like l-dopa or apomorphine which are known to increase dopamine levels or to possess dopamine-like effects. Metoclopramide also abolishes the slowing of gastric emptying caused by apomorphine. Like the phenothiazines and related drugs, which are also dopamine antagonists, metoclopramide produces sedation and may produce extrapyramidal reactions, although these are comparatively rare (see WARNINGS). Metoclopramide inhibits the central and peripheral effects of apomorphine, induces release of prolactin and causes a transient increase in circulating aldosterone levels, which may be associated with transient fluid retention. The onset of pharmacological action of metoclopramide is 1 to 3 minutes following an intravenous dose, 10 to 15 minutes following intramuscular administration, and 30 to 60 minutes following an oral dose; pharmacological effects persist for 1 to 2 hours. Reference ID: 3018416 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda Pharmacokinetics Metoclopramide is rapidly and well absorbed. Relative to an intravenous dose of 20 mg, the absolute oral bioavailability of metoclopramide is 80% ± 15.5% as demonstrated in a crossover study of 18 subjects. Peak plasma concentrations occur at about 1 to 2 hr after a single oral dose. Similar time to peak is observed after individual doses at steady state. In a single dose study of 12 subjects, the area under the drug concentration-time curve increases linearly with doses from 20 to 100 mg. Peak concentrations increase linearly with dose; time to peak concentrations remains the same; whole body clearance is unchanged; and the elimination rate remains the same. The average elimination half-life in individuals with normal renal function is 5 to 6 hr. Linear kinetic processes adequately describe the absorption and elimination of metoclopramide. Approximately 85% of the radioactivity of an orally administered dose appears in the urine within 72 hr. Of the 85% eliminated in the urine, about half is present as free or conjugated metoclopramide. The drug is not extensively bound to plasma proteins (about 30%). The whole body volume of distribution is high (about 3.5 L/kg) which suggests extensive distribution of drug to the tissues. Renal impairment affects the clearance of metoclopramide. In a study with patients with varying degrees of renal impairment, a reduction in creatinine clearance was correlated with a reduction in plasma clearance, renal clearance, non-renal clearance, and increase in elimination half-life. The kinetics of metoclopramide in the presence of renal impairment remained linear however. The reduction in clearance as a result of renal impairment suggests that adjustment downward of maintenance dosage should be done to avoid drug accumulation. Adult Pharmacokinetic Data Parameter Value Vd (L/kg) ~ 3.5 Plasma Protein Binding ~ 30% t1/2 (hr) 5 to 6 Oral Bioavailability 80%±15.5% In pediatric patients, the pharmacodynamics of metoclopramide following oral and intravenous administration are highly variable and a concentration-effect relationship has not been established. There are insufficient reliable data to conclude whether the pharmacokinetics of metoclopramide in adults and the pediatric population are similar. Although there are insufficient data to support the efficacy of metoclopramide in pediatric patients with symptomatic gastroesophageal reflux (GER) or cancer chemotherapy-related nausea and vomiting, its pharmacokinetics have been studied in these patient populations. Reference ID: 3018416 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda In an open-label study, six pediatric patients (age range, 3.5 weeks to 5.4 months) with GER received metoclopramide 0.15 mg/kg oral solution every 6 hours for 10 doses. The mean peak plasma concentration of metoclopramide after the tenth dose was 2-fold (56.8 μg/L) higher compared to that observed after the first dose (29 μg/L) indicating drug accumulation with repeated dosing. After the tenth dose, the mean time to reach peak concentrations (2.2 hr), half-life (4.1 hr), clearance (0.67 L/h/kg), and volume of distribution (4.4 L/kg) of metoclopramide were similar to those observed after the first dose. In the youngest patient (age, 3.5 weeks), metoclopramide half-life after the first and the tenth dose (23.1 and 10.3 hr, respectively) was significantly longer compared to other infants due to reduced clearance. This may be attributed to immature hepatic and renal systems at birth. Single intravenous doses of metoclopramide 0.22 to 0.46 mg/kg (mean, 0.35 mg/kg) were administered over 5 minutes to 9 pediatric cancer patients receiving chemotherapy (mean age, 11.7 years; range, 7 to 14 yr) for prophylaxis of cytotoxic-induced vomiting. The metoclopramide plasma concentrations extrapolated to time zero ranged from 65 to 395 μg/L (mean, 152 μg/L). The mean elimination half-life, clearance, and volume of distribution of metoclopramide were 4.4 hr (range, 1.7 to 8.3 hr), 0.56 L/h/kg (range, 0.12 to 1.20 L/h/kg), and 3.0 L/kg (range, 1.0 to 4.8 L/kg), respectively. In another study, nine pediatric cancer patients (age range, 1 to 9 yr) received 4 to 5 intravenous infusions (over 30 minutes) of metoclopramide at a dose of 2 mg/kg to control emesis. After the last dose, the peak serum concentrations of metoclopramide ranged from 1060 to 5680 μg/L. The mean elimination half-life, clearance, and volume of distribution of metoclopramide were 4.5 hr (range, 2.0 to 12.5 hr), 0.37 L/h/kg (range, 0.10 to 1.24 L/h/kg), and 1.93 L/kg (range, 0.95 to 5.50 L/kg), respectively. INDICATIONS AND USAGE The use of reglan® tablets is recommended for adults only. Therapy should not exceed 12 weeks in duration. Symptomatic Gastroesophageal Reflux reglan® tablets are indicated as short-term (4 to 12 weeks) therapy for adults with symptomatic, documented gastroesophageal reflux who fail to respond to conventional therapy. The principal effect of metoclopramide is on symptoms of postprandial and daytime heartburn with less observed effect on nocturnal symptoms. If symptoms are confined to particular situations, such as following the evening meal, use of metoclopramide as single doses prior to the provocative situation should be considered, rather than using the drug throughout the day. Healing of esophageal ulcers and erosions has been endoscopically demonstrated at the end of a 12-week trial using doses of 15 mg q.i.d. As there is no documented correlation between symptoms and healing of esophageal lesions, patients with documented lesions should be monitored endoscopically. Diabetic Gastroparesis (Diabetic Gastric Stasis) reglan® tablets (metoclopramide tablets, USP) is indicated for the relief of symptoms associated with acute and recurrent diabetic gastric stasis. The usual manifestations of Reference ID: 3018416 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda delayed gastric emptying (e.g., nausea, vomiting, heartburn, persistent fullness after meals, and anorexia) appear to respond to reglan® within different time intervals. Significant relief of nausea occurs early and continues to improve over a three-week period. Relief of vomiting and anorexia may precede the relief of abdominal fullness by one week or more. CONTRAINDICATIONS Metoclopramide should not be used whenever stimulation of gastrointestinal motility might be dangerous, e.g., in the presence of gastrointestinal hemorrhage, mechanical obstruction, or perforation. Metoclopramide is contraindicated in patients with pheochromocytoma because the drug may cause a hypertensive crisis, probably due to release of catecholamines from the tumor. Such hypertensive crises may be controlled by phentolamine. Metoclopramide is contraindicated in patients with known sensitivity or intolerance to the drug. Metoclopramide should not be used in epileptics or patients receiving other drugs which are likely to cause extrapyramidal reactions, since the frequency and severity of seizures or extrapyramidal reactions may be increased. WARNINGS Mental depression has occurred in patients with and without prior history of depression. Symptoms have ranged from mild to severe and have included suicidal ideation and suicide. Metoclopramide should be given to patients with a prior history of depression only if the expected benefits outweigh the potential risks. Extrapyramidal symptoms, manifested primarily as acute dystonic reactions, occur in approximately 1 in 500 patients treated with the usual adult dosages of 30 to 40 mg/day of metoclopramide. These usually are seen during the first 24 to 48 hours of treatment with metoclopramide, occur more frequently in pediatric patients and adult patients less than 30 years of age and are even more frequent at higher doses. These symptoms may include involuntary movements of limbs and facial grimacing, torticollis, oculogyric crisis, rhythmic protrusion of tongue, bulbar type of speech, trismus, or dystonic reactions resembling tetanus. Rarely, dystonic reactions may present as stridor and dyspnea, possibly due to laryngospasm. If these symptoms should occur, inject 50 mg diphenhydramine hydrochloride intramuscularly, and they usually will subside. Benztropine mesylate, 1 to 2 mg intramuscularly, may also be used to reverse these reactions. Parkinsonian-like symptoms have occurred, more commonly within the first 6 months after beginning treatment with metoclopramide, but occasionally after longer periods. These symptoms generally subside within 2 to 3 months following discontinuance of metoclopramide. Patients with preexisting Parkinson’s disease should be given metoclopramide cautiously, if at all, since such patients may experience exacerbation of parkinsonian symptoms when taking metoclopramide. Reference ID: 3018416 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda Tardive Dyskinesia (See Boxed Warnings) Treatment with metoclopramide can cause tardive dyskinesia (TD), a potentially irreversible and disfiguring disorder characterized by involuntary movements of the face, tongue, or extremities. The risk of developing tardive dyskinesia increases with the duration of treatment and the total cumulative dose. An analysis of utilization of patterns showed that about 20% of patients who used metoclopramide took it longer than 12 weeks. Treatment with metoclopramide for longer than the recommended 12 weeks should be avoided in all but rare cases where therapeutic benefit is thought to outweigh the risk of developing TD. Although the risk of developing TD in the general population may be increased among the elderly, women, and diabetics, it is not possible to predict which patients will develop metoclopramide-induced TD. Both the risk of developing TD and the likelihood that TD will become irreversible increase with duration of treatment and total cumulative dose. Metoclopramide should be discontinued in patients who develop signs and symptoms of TD. There is no known effective treatment for established cases of TD, although in some patients, TD may remit, partially or completely, within several weeks to months after metoclopramide is withdrawn. Metoclopramide itself may suppress, or partially suppress, the signs of TD, thereby masking the underlying disease process. The effect of this symptomatic suppression upon the long-term course of TD is unknown. Therefore, metoclopramide should not be used for the symptomatic control of TD. Neuroleptic Malignant Syndrome (NMS) There have been rare reports of an uncommon but potentially fatal symptom complex sometimes referred to as Neuroleptic Malignant Syndrome (NMS) associated with metoclopramide. Clinical manifestations of NMS include hyperthermia, muscle rigidity, altered consciousness, and evidence of autonomic instability (irregular pulse or blood pressure, tachycardia, diaphoresis and cardiac arrhythmias). The diagnostic evaluation of patients with this syndrome is complicated. In arriving at a diagnosis, it is important to identify cases where the clinical presentation includes both serious medical illness (e.g., pneumonia, systemic infection, etc.) and untreated or inadequately treated extrapyramidal signs and symptoms (EPS). Other important considerations in the differential diagnosis include central anticholinergic toxicity, heat stroke, malignant hyperthermia, drug fever and primary central nervous system (CNS) pathology. The management of NMS should include 1) immediate discontinuation of metoclopramide and other drugs not essential to concurrent therapy, 2) intensive symptomatic treatment and medical monitoring, and 3) treatment of any concomitant serious medical problems for which specific treatments are available. Bromocriptine and dantrolene sodium have been used in treatment of NMS, but their effectiveness have not been established (see ADVERSE REACTIONS). Reference ID: 3018416 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda PRECAUTIONS General In one study in hypertensive patients, intravenously administered metoclopramide was shown to release catecholamines; hence, caution should be exercised when metoclopramide is used in patients with hypertension. Because metoclopramide produces a transient increase in plasma aldosterone, certain patients, especially those with cirrhosis or congestive heart failure, may be at risk of developing fluid retention and volume overload. If these side effects occur at any time during metoclopramide therapy, the drug should be discontinued. Adverse reactions, especially those involving the nervous system, may occur after stopping the use of reglan®. A small number of patients may experience a withdrawal period after stopping reglan® that could include dizziness, nervousness, and/or headaches. Information for Patients The use of reglan® is recommended for adults only. Metoclopramide may impair the mental and/or physical abilities required for the performance of hazardous tasks such as operating machinery or driving a motor vehicle. The ambulatory patient should be cautioned accordingly. For additional information, patients should be instructed to see the Medication Guide for reglan® tablets. Drug Interactions The effects of metoclopramide on gastrointestinal motility are antagonized by anticholinergic drugs and narcotic analgesics. Additive sedative effects can occur when metoclopramide is given with alcohol, sedatives, hypnotics, narcotics, or tranquilizers. The finding that metoclopramide releases catecholamines in patients with essential hypertension suggests that it should be used cautiously, if at all, in patients receiving monoamine oxidase inhibitors. Absorption of drugs from the stomach may be diminished (e.g., digoxin) by metoclopramide, whereas the rate and/or extent of absorption of drugs from the small bowel may be increased (e.g., acetaminophen, tetracycline, levodopa, ethanol, cyclosporine). Gastroparesis (gastric stasis) may be responsible for poor diabetic control in some patients. Exogenously administered insulin may begin to act before food has left the stomach and lead to hypoglycemia. Because the action of metoclopramide will influence the delivery of food to the intestines and thus the rate of absorption, insulin dosage or timing of dosage may require adjustment. Carcinogenesis, Mutagenesis, Impairment of Fertility A 77-week study was conducted in rats with oral doses up to about 40 times the maximum recommended human daily dose. Metoclopramide elevates prolactin levels and the elevation persists during chronic administration. Tissue culture experiments indicate that approximately one-third of human breast cancers are prolactin-dependent in vitro, a Reference ID: 3018416 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda factor of potential importance if the prescription of metoclopramide is contemplated in a patient with previously detected breast cancer. Although disturbances such as galactorrhea, amenorrhea, gynecomastia, and impotence have been reported with prolactin-elevating drugs, the clinical significance of elevated serum prolactin levels is unknown for most patients. An increase in mammary neoplasms has been found in rodents after chronic administration of prolactin-stimulating neuroleptic drugs and metoclopramide. Neither clinical studies nor epidemiologic studies conducted to date, however, have shown an association between chronic administration of these drugs and mammary tumorigenesis; the available evidence is too limited to be conclusive at this time. An Ames mutagenicity test performed on metoclopramide was negative. Pregnancy Category B Reproduction studies performed in rats, mice and rabbits by the I.V., I.M., S.C., and oral routes at maximum levels ranging from 12 to 250 times the human dose have demonstrated no impairment of fertility or significant harm to the fetus due to metoclopramide. There are, however, no adequate and well-controlled studies in pregnant women. Because animal reproduction studies are not always predictive of human response, this drug should be used during pregnancy only if clearly needed. Nursing Mothers Metoclopramide is excreted in human milk. Caution should be exercised when metoclopramide is administered to a nursing mother. Pediatric Use Safety and effectiveness in pediatric patients have not been established (see OVERDOSAGE). Care should be exercised in administering metoclopramide to neonates since prolonged clearance may produce excessive serum concentrations (see CLINICAL PHARMACOLOGY - Pharmacokinetics). In addition, neonates have reduced levels of NADH-cytochrome b5 reductase which, in combination with the aforementioned pharmacokinetic factors, make neonates more susceptible to methemoglobinemia (see OVERDOSAGE). The safety profile of metoclopramide in adults cannot be extrapolated to pediatric patients. Dystonias and other extrapyramidal reactions associated with metoclopramide are more common in the pediatric population than in adults. (See WARNINGS and ADVERSE REACTIONS - Extrapyramidal Reactions.) Geriatric Use Clinical studies of reglan® did not include sufficient numbers of subjects aged 65 and over to determine whether elderly subjects respond differently from younger subjects. The risk of developing parkinsonian-like side effects increases with ascending dose. Geriatric patients should receive the lowest dose of reglan® that is effective. If parkinsonian-like symptoms develop in a geriatric patient receiving reglan®, reglan® Reference ID: 3018416 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda should generally be discontinued before initiating any specific anti-parkinsonian agents (see WARNINGS and DOSAGE AND ADMINISTRATION – For the Relief of Symptomatic Gastroesophageal Reflux). The elderly may be at greater risk for tardive dyskinesia (see WARNINGS – Tardive Dyskinesia). Sedation has been reported in reglan® users. Sedation may cause confusion and manifest as over-sedation in the elderly (see CLINICAL PHARMACOLOGY, PRECAUTIONS – Information for Patients and ADVERSE REACTIONS – CNS Effects). reglan® is known to be substantially excreted by the kidney, and the risk of toxic reactions to this drug may be greater in patients with impaired renal function (see DOSAGE AND ADMINISTRATION – Use in Patients with Renal or Hepatic Impairment). For these reasons, dose selection for an elderly patient should be cautious, usually starting at the low end of the dosing range, reflecting the greater frequency of decreased renal function, concomitant disease, or other drug therapy in the elderly (see DOSAGE AND ADMINISTRATION – For the Relief of Symptomatic Gastroesophageal Reflux and Use in Patients with Renal or Hepatic Impairment). Other Special Populations Patients with NADH-cytochrome b5 reductase deficiency are at an increased risk of developing methemoglobinemia and/or sulfhemoglobinemia when metoclopramide is administered. In patients with G6PD deficiency who experience metoclopramide- induced methemoglobinemia, methylene blue treatment is not recommended (see OVERDOSAGE). ADVERSE REACTIONS In general, the incidence of adverse reactions correlates with the dose and duration of metoclopramide administration. The following reactions have been reported, although in most instances, data do not permit an estimate of frequency: CNS Effects Restlessness, drowsiness, fatigue, and lassitude occur in approximately 10% of patients receiving the most commonly prescribed dosage of 10 mg q.i.d. (see PRECAUTIONS). Insomnia, headache, confusion, dizziness, or mental depression with suicidal ideation (see WARNINGS) occur less frequently. The incidence of drowsiness is greater at higher doses. There are isolated reports of convulsive seizures without clearcut relationship to metoclopramide. Rarely, hallucinations have been reported. Extrapyramidal Reactions (EPS) Acute dystonic reactions, the most common type of EPS associated with metoclopramide, occur in approximately 0.2% of patients (1 in 500) treated with 30 to 40 mg of metoclopramide per day. Symptoms include involuntary movements of limbs, facial grimacing, torticollis, oculogyric crisis, rhythmic protrusion of tongue, bulbar type of Reference ID: 3018416 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda speech, trismus, opisthotonus (tetanus-like reactions), and, rarely, stridor and dyspnea possibly due to laryngospasm; ordinarily these symptoms are readily reversed by diphenhydramine (see WARNINGS). Parkinsonian-like symptoms may include bradykinesia, tremor, cogwheel rigidity, mask­ like facies (see WARNINGS). Tardive dyskinesia most frequently is characterized by involuntary movements of the tongue, face, mouth, or jaw, and sometimes by involuntary movements of the trunk and/or extremities; movements may be choreoathetotic in appearance (see WARNINGS). Motor restlessness (akathisia) may consist of feelings of anxiety, agitation, jitteriness, and insomnia, as well as inability to sit still, pacing, foot tapping. These symptoms may disappear spontaneously or respond to a reduction in dosage. Neuroleptic Malignant Syndrome Rare occurrences of neuroleptic malignant syndrome (NMS) have been reported. This potentially fatal syndrome is comprised of the symptom complex of hyperthermia, altered consciousness, muscular rigidity, and autonomic dysfunction (see WARNINGS). Endocrine Disturbances Galactorrhea, amenorrhea, gynecomastia, impotence secondary to hyperprolactinemia (see PRECAUTIONS). Fluid retention secondary to transient elevation of aldosterone (see CLINICAL PHARMACOLOGY). Cardiovascular Hypotension, hypertension, supraventricular tachycardia, bradycardia, fluid retention, acute congestive heart failure and possible AV block (see CONTRAINDICATIONS and PRECAUTIONS). Gastrointestinal Nausea and bowel disturbances, primarily diarrhea. Hepatic Rarely, cases of hepatotoxicity, characterized by such findings as jaundice and altered liver function tests, when metoclopramide was administered with other drugs with known hepatotoxic potential. Renal Urinary frequency and incontinence. Hematologic A few cases of neutropenia, leukopenia, or agranulocytosis, generally without clearcut relationship to metoclopramide. Methemoglobinemia, in adults and especially with overdosage in neonates (see OVERDOSAGE). Sulfhemoglobinemia in adults. Reference ID: 3018416 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda Allergic Reactions A few cases of rash, urticaria, or bronchospasm, especially in patients with a history of asthma. Rarely, angioneurotic edema, including glossal or laryngeal edema. Miscellaneous Visual disturbances. Porphyria. OVERDOSAGE Symptoms of overdosage may include drowsiness, disorientation and extrapyramidal reactions. Anticholinergic or antiparkinson drugs or antihistamines with anticholinergic properties may be helpful in controlling the extrapyramidal reactions. Symptoms are self- limiting and usually disappear within 24 hours. Hemodialysis removes relatively little metoclopramide, probably because of the small amount of the drug in blood relative to tissues. Similarly, continuous ambulatory peritoneal dialysis does not remove significant amounts of drug. It is unlikely that dosage would need to be adjusted to compensate for losses through dialysis. Dialysis is not likely to be an effective method of drug removal in overdose situations. Unintentional overdose due to misadministration has been reported in infants and children with the use of metoclopramide oral solution. While there was no consistent pattern to the reports associated with these overdoses, events included seizures, extrapyramidal reactions, and lethargy. Methemoglobinemia has occurred in premature and full-term neonates who were given overdoses of metoclopramide (1 to 4 mg/kg/day orally, intramuscularly or intravenously for 1 to 3 or more days). Methemoglobinemia can be reversed by the intravenous administration of methylene blue. However, methylene blue may cause hemolytic anemia in patients with G6PD deficiency, which may be fatal (see PRECAUTIONS – Other Special Populations). DOSAGE AND ADMINISTRATION Therapy with reglan® tablets should not exceed 12 weeks in duration. For the relief of Symptomatic Gastroesophageal Reflux Administer from 10 mg to 15 mg reglan® (metoclopramide hydrochloride, USP) orally up to q.i.d. 30 minutes before each meal and at bedtime, depending upon symptoms being treated and clinical response (see CLINICAL PHARMACOLOGY and INDICATIONS AND USAGE). If symptoms occur only intermittently or at specific times of the day, use of metoclopramide in single doses up to 20 mg prior to the provoking situation may be preferred rather than continuous treatment. Occasionally, patients (such as elderly patients) who are more sensitive to the therapeutic or adverse effects of metoclopramide will require only 5 mg per dose. Experience with esophageal erosions and ulcerations is limited, but healing has thus far been documented in one controlled trial using q.i.d. therapy at 15 mg/dose, and this regimen should be used when lesions are present, so long as it is tolerated (see ADVERSE REACTIONS). Because of the poor correlation between symptoms and Reference ID: 3018416 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda endoscopic appearance of the esophagus, therapy directed at esophageal lesions is best guided by endoscopic evaluation. Therapy longer than 12 weeks has not been evaluated and cannot be recommended. For the Relief of Symptoms Associated with Diabetic Gastroparesis (Diabetic Gastric Stasis) Administer 10 mg of metoclopramide 30 minutes before each meal and at bedtime for two to eight weeks, depending upon response and the likelihood of continued well-being upon drug discontinuation. The initial route of administration should be determined by the severity of the presenting symptoms. If only the earliest manifestations of diabetic gastric stasis are present, oral administration of reglan® may be initiated. However, if severe symptoms are present, therapy should begin with metoclopramide injection (consult labeling of the injection prior to initiating parenteral administration). Administration of metoclopramide injection up to 10 days may be required before symptoms subside, at which time oral administration may be instituted. Since diabetic gastric stasis is frequently recurrent, reglan® therapy should be reinstituted at the earliest manifestation. Use in Patients with Renal or Hepatic Impairment Since metoclopramide is excreted principally through the kidneys, in those patients whose creatinine clearance is below 40 mL/min, therapy should be initiated at approximately one-half the recommended dosage. Depending upon clinical efficacy and safety considerations, the dosage may be increased or decreased as appropriate. See OVERDOSAGE section for information regarding dialysis. Metoclopramide undergoes minimal hepatic metabolism, except for simple conjugation. Its safe use has been described in patients with advanced liver disease whose renal function was normal.

There may be new information. If you take another product that contains metoclopramide (such as REGLAN injection, REGLAN ODT, or metoclopramide oral syrup), you should read the Medication Guide that comes with that product. Some of the information may be different. This Medication Guide does not take the place of talking with your doctor about your medical condition or your treatment. What is the most important information I should know about REGLAN? REGLAN can cause serious side effects, including: Tardive dyskinesia (abnormal muscle movements). These movements happen mostly in the face muscles. You can not control these movements. They may not go away even after stopping REGLAN. There is no treatment for tardive dyskinesia, but symptoms may lessen or go away over time after you stop taking REGLAN. Your chances for getting tardive dyskinesia go up: • the longer you take REGLAN and the more REGLAN you take. You should not take REGLAN for more than 12 weeks. • if you are older, especially if you are a woman • if you have diabetes It is not possible for your doctor to know if you will get tardive dyskinesia if you take REGLAN. Call your doctor right away if you get movements you can not stop or control, such as: • lip smacking, chewing, or puckering up your mouth • frowning or scowling • sticking out your tongue • blinking and moving your eyes • shaking of your arms and legs Reference ID: 3018416 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda See the section "What are the possible side effects of REGLAN?" for more information about side effects. What is REGLAN? REGLAN is a prescription medicine used: • in adults for 4 to 12 weeks to relieve heartburn symptoms with gastroesophageal reflux disease (GERD) when certain other treatments do not work. REGLAN relieves daytime heartburn and heartburn after meals. It also helps ulcers in the esophagus to heal. • to relieve symptoms of slow stomach emptying in people with diabetes. REGLAN helps treat symptoms such as nausea, vomiting, heartburn, feeling full long after a meal, and loss of appetite. Not all these symptoms get better at the same time. It is not known if REGLAN is safe and works in children. Who should not take REGLAN? Do not take REGLAN if you: • have stomach or intestine problems that could get worse with REGLAN, such as bleeding, blockage or a tear in the stomach or bowel wall • have an adrenal gland tumor called a pheochromocytoma • are allergic to REGLAN or anything in it. See the end of this Medication Guide for a list of ingredients in REGLAN. • take medicines that can cause uncontrolled movements, such as medicines for mental illness • have seizures What should I tell my doctor before taking REGLAN? Tell your doctor about all your medical conditions, including if you have: • depression • Parkinson's disease • high blood pressure • kidney problems. Your doctor may start with a lower dose. • liver problems or heart failure. REGLAN may cause your body to hold fluids. • diabetes. Your dose of insulin may need to be changed. • breast cancer • you are pregnant or plan to become pregnant. It is not known if REGLAN will harm your unborn baby. • you are breast-feeding. REGLAN can pass into breast milk and may harm your baby. Talk with your doctor about the best way to feed your baby if you take REGLAN.

REGLAN may cause sleepiness. What are the possible side effects of REGLAN? Reglan can cause serious side effects, including: • Tardive dyskinesia (abnormal muscle movements). See "What is the most important information I need to know about REGLAN?" • Uncontrolled spasms of your face and neck muscles, or muscles of your body, arms, and legs (dystonia). These muscle spasms can cause abnormal movements Reference ID: 3018416 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda and body positions. These spasms usually start within the first 2 days of treatment. These spasms happen more often in children and adults under age 30. • Depression, thoughts about suicide, and suicide. Some people who take REGLAN become depressed. You may have thoughts about hurting or killing yourself. Some people who take Reglan have ended their own lives (suicide). • Neuroleptic Malignant Syndrome (NMS). NMS is a very rare but very serious condition that can happen with Reglan. NMS can cause death and must be treated in a hospital. Symptoms of NMS include: high fever, stiff muscles, problems thinking, very fast or uneven heartbeat, and increased sweating. • Parkinsonism. Symptoms include slight shaking, body stiffness, trouble moving or keeping your balance. If you already have Parkinson's disease, your symptoms may become worse while you are receiving REGLAN. Call your doctor and get medical help right away if you: • feel depressed or have thoughts about hurting or killing yourself • have high fever, stiff muscles, problems thinking, very fast or uneven heartbeat, and increased sweating • have muscle movements you cannot stop or control • have muscle movements that are new or unusual Common side effects of Reglan include: • feeling restless, sleepy, tired, dizzy, or exhausted • headache • confusion • trouble sleeping You may have more side effects the longer you take REGLAN and the more REGLAN you take. You may still have side effects after stopping REGLAN. You may have symptoms from stopping (withdrawal) REGLAN such as headaches, and feeling dizzy or nervous.

In pediatric patients: o gastroesophageal and pulmonary aspiration studies: 3.7 to 11.1 MBq (0.10 to 0.30 mCi) by oral or nasogastric tube administration. For oral administration, combine the radiopharmaceutical with a milk feeding. For nasogastric tube administration, administer the radiopharmaceutical into the stomach then instill a normal volume of dextrose or milk feeding. 2.2 Drug Preparation and Administration  The contents of the two Solution vials, the Solution A vial containing the appropriate acidic solution and the Solution B vial containing the appropriate buffer solution, are intended only for use in the preparation of the Technetium Tc 99m Sulfur Colloid Injection and are not to be directly administered to the patient.  Do not use Sodium Pertechnetate Tc 99m containing oxidants to reconstitute this kit.  The contents of the kit are not radioactive. However, after the Sodium Pertechnetate Tc 99m is added, maintain adequate shielding of the final preparation. Wear waterproof gloves during the preparation procedure.  Do not use Sodium Pertechnetate Tc 99m containing more than 10 micrograms per mL of aluminum ion because a flocculent precipitate may occur and such a precipitate may localize in the lung.  The contents of the kit are sterile and non-pyrogenic. This preparation contains no bacteriostatic preservative. Follow the directions carefully and adhere strictly to aseptic procedures during preparation. Prepare Technetium Tc 99m Sulfur Colloid Injection by the following aseptic procedure: 1. Remove the dark brown plastic cap from the Sulfur Colloid multi-dose Reaction Vial and swab the top of the vial closure with alcohol to sterilize the surface. Complete the radiation label and affix to the vial. Place the vial in an appropriate lead-capped radiation shield labeled and identified. 2. With a sterile shielded syringe, aseptically obtain 1 to 3 mL of a suitable, oxidant-free sterile and non-pyrogenic Sodium Pertechnetate Tc 99m, each milliliter containing a maximum activity of 18,500 MBq (500 mCi). 3. Aseptically add the Sodium Pertechnetate Tc 99m to the vial. 4. Place a lead cover on the vial shield and dissolve the reagent by gentle swirling. 5. Just before use, remove the red cap from the Solution A vial and swab the top of the vial closure with alcohol to sterilize the surface. Using a sterile needle and syringe, aseptically withdraw 1.5 mL Solution A from the vial. Aseptically Inject 1.5mL Solution A into the multi-dose Reaction Vial and swirl again. 6. Transfer the multi-dose Reaction Vial from vial shield and place in a vigorously boiling water bath (water bath should be shielded with 1/8” to 1/4” lead) deep enough to cover the entire liquid contents of the vial. Keep the vial in the water bath for five minutes. 7. Remove the multi-dose Reaction Vial from the water bath and place in the lead shield and allow to cool for three minutes. Swab the vial closure again with an antiseptic. Page 2 Reference ID: 3173576 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda 8. Just before use, remove the blue cap from the Solution B vial and swab the top of the vial closure with alcohol to sterilize the surface. Using a sterile needle and syringe, aseptically withdraw 1.5 mL Solution B from the vial. Aseptically Inject 1.5 mL Solution B into the multi-dose Reaction Vial and swirl again. 9. Record time and date of preparation. 10. Allow the preparation to cool to body temperature before use. Maintain adequate shielding of the radioactive colloid preparation at all times. 11. Where appropriate, dilute the preparation with sterile Sodium Chloride Injection to bring the dosage to within the recommended range. 12. Mix the multi-dose Reaction Vial and aseptically withdraw material with a sterile shielded syringe for use within 6 hours of preparation. For optimum results this time should be minimized. The vial contains no bacteriostatic preservative. Store the reconstituted vial at 20 to 25°C (68 to77°F). Discard vial 6 hours after reconstitution. 13. Carefully agitate the shielded syringe immediately prior to administration of sulfur colloid to avoid particles aggregation and non-uniform distribution of radioactivity. Measure the patient dose by a suitable radioactivity calibration system immediately before administration. Check radiochemical purity before patient administration. Inspect Technetium Tc 99m Sulfur Colloid Injection visually for particulate matter and discoloration before administration, whenever solution and container permit. Do not administer the drug if it contains particulate matter or discoloration; dispose of these unacceptable or unused preparations in a safe manner, in compliance with applicable regulations. 2.3 Radiation Dosimetry  Subcutaneous injection to assist in lymph node localization Table 1.

Visual inspection was performed to identify the blue-labeled nodes and a hand held gamma counter was used to identify nodes concentrating the radiopharmaceutical. Multiple methods were used to detect the concentrated radioactivity within lymph nodes. For example, investigators used thresholds of background radioactivity to localize nodes containing a minimum of radioactive counts 3 times higher than the background or containing at least 10 fold higher counts than contiguous nodes.  In clinical studies of patients with malignant melanoma, preoperative lymphoscintigraphy was usually performed using planar imaging techniques to establish a road map of nodal basins and to facilitate intraoperative identification of lymph nodes. [see Clinical Studies (14)]  Technetium Tc 99m Sulfur Colloid Injection and other tracers may not localize all lymph nodes and the tracers may differ in their extent of lymph node localization. The lymph node localization of Technetium Tc 99m Sulfur Colloid Injection is dependent upon the underlying patency and structure of the lymphatic system, the extent of functional reticuloendothelial cells within lymph nodes and the radiopharmaceutical injection technique. Distortion of the Page 5 Reference ID: 3173576 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda underlying lymphatic system architecture and function by prior surgery, radiation or extensive metastatic disease may result in failure of the radiopharmaceutical and other tracers to localize lymph nodes. The use of Technetium Tc 99m Sulfur Colloid Injection is intended to supplement palpation, visual inspection and other procedures important to lymph node localization. [see Clinical Studies (14)] Peritoneo-venous (LeVeen) shunt setting in adults: Following administration of Technetium Tc 99m Sulfur Colloid Injection into the peritoneal cavity, the radiopharmaceutical mixes with the peritoneal fluid. Clearance from the peritoneal cavity varies from insignificant, which may occur with complete shunt blockage, to very rapid clearance with subsequent transfer into the systemic circulation when the shunt is patent. Following transfer into the systemic circulation, the radiopharmaceutical concentrates within the liver (a target organ). Obtain serial images of both the shunt and liver. An adequate evaluation of the difference between total blockage of the shunt and partial blockage may not be feasible in all cases. Transperitoneal absorption of sulfur colloid into the systemic circulation may occur, but it occurs slowly. Therefore, the most definitive scintigraphic evaluation of shunt patency will generally be obtained if there is visualization of both the shunt itself and the liver and/or spleen within the first three hours post intraperitoneal injection of the radiopharmaceutical. Imaging areas of functioning reticuloendothelial cells in liver, spleen or bone marrow: Altered biodistribution with lung and soft tissue uptake instead of reticuloendothelial system has been reported after intravenous injection. The size and physical-chemical properties of the sulfur colloid particles formed from the components of the kit may determine the biodistribution of the colloid and its uptake by the reticuloendothelial system. Diseases affecting the reticuloendothelial system may also alter the expected uptake pattern. Gastroesophageal and pulmonary aspiration imaging studies: To facilitate the imaging of gastroesophageal reflux consider administering Sulfur Colloid by nasogastric tube. 3 DOSAGE FORMS AND STRENGTHS Kit for the Preparation of Technetium Tc 99m Sulfur Colloid Injection is supplied in a package that contains 5 kits. All components of a kit are sterile and non-pyrogenic. Each 10mL multi-dose Reaction Vial contains, in lyophilized form, 2 mg sodium thiosulfate anhydrous, 2.3 mg edetate disodium and 18.1 mg bovine gelatin; each Solution A vial contains 1.8 mL 0.148 N hydrochloric acid solution and each Solution B vial contains 1.8 mL aqueous solution of 24.6 mg/mL sodium biphosphate anhydrous and 7.9 mg/mL sodium hydroxide. Included in each 5-kit package are one package insert and 10 radiation labels. 4 CONTRAINDICATIONS None 5 WARNINGS AND PRECAUTIONS 5.1 Anaphylactic reactions Anaphylactic reactions with bronchospasm, hypotension, urticaria and rare fatalities have occurred following intravenously administered Technetium Tc 99m Sulfur Colloid Injection. Have emergency resuscitation equipment and personnel immediately available. 5.2 Radiation Risks Radiation-emitting products, including Technetium Tc 99m Sulfur Colloid Injection, may increase the risk for cancer, especially in pediatric patients. Use the smallest dose necessary for imaging and ensure safe handling to protect the patient and health care worker. [see Dosage and Administration (2.3)] 5.3 Altered distribution, Accumulation of Tracer in the Lungs Technetium Tc 99m Sulfur Colloid Injection is physically unstable, and the particles will settle with time or with exposure to polyvalent cations. These larger particles are likely to be trapped by the pulmonary capillary bed following intravenous injection and result in non-uniform distribution of radioactivity. Agitate the vial adequately before administration of sulfur colloid to avoid particle aggregation and non-uniform distribution of radioactivity. Discard unused drug after 6 hours from the time of formulation. [see Dosage and Administration (2.2)] 6 ADVERSE REACTIONS The most frequently reported adverse reactions, across all categories of use and routes of administration, include rash, allergic reaction, urticaria, anaphylaxis/anaphylactic shock, and hypotension. Less frequently reported adverse reactions are fatal cardiopulmonary arrest, seizures, dyspnea, bronchospasm, abdominal pain, flushing, nausea, vomiting, itching, fever, chills, perspiration, numbness, and dizziness. Local injection site reactions, including burning, blanching, erythema, sclerosis, swelling, eschar, and scarring, have also been reported. 7 DRUG INTERACTIONS Specific drug-drug interactions have not been studied. 8 USE IN SPECIFIC POPULATIONS 8.1 Pregnancy Pregnancy Category C: Technetium Tc 99m crosses the placenta. Among 14 infants born to pregnant patients exposed to Technetium Tc 99m Sulfur Colloid Injection for lymph node localization, no birth defects were reported following drug exposure. Animal reproduction studies have not been conducted with Technetium Tc 99m Page 6 Reference ID: 3173576 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda Sulfur Colloid Injection. Technetium Tc 99m Sulfur Colloid Injection should be given to a pregnant woman only if clearly needed. All radiopharmaceuticals, including Technetium Tc 99m Sulfur Colloid Injection, have a potential to cause fetal harm. The likelihood of fetal harm depends on the stage of fetal development and the magnitude of the radiopharmaceutical dose. Assess pregnancy status before administering Technetium Tc 99m Sulfur Colloid Injection to a female of reproductive potential. 8.3 Nursing Mothers Technetium Tc 99m is excreted in human milk during lactation. If nursing, patients should express and discard milk for a minimum of 6 hours after administration of Technetium Tc 99m Sulfur Colloid Injection. Following higher dose procedures [greater than 370 MBq (10 mCi)], patients should minimize close contact with infants for 6 hours after receiving a Technetium Tc 99m Sulfur Colloid Injection. 8.4 Pediatric Use The safety and efficacy of Technetium Tc 99m Sulfur Colloid kit in pediatric patients has been shown for the following indications: liver, spleen, and bone marrow imaging, and gastroesophageal and pulmonary aspiration studies. 8.5 Geriatric Use Clinical studies of Kit for the Preparation of Technetium Tc 99m Sulfur Colloid Injection did not include sufficient numbers of subjects aged 65 and over to determine whether they respond differently from younger subjects. 8.6 Females of Reproductive Potential In females of reproductive potential, imaging procedures with Technetium Tc 99m Sulfur Colloid Injection should be performed within ten days following the onset of menses or a pregnancy test should be performed within 48 hours of the procedure. 10 OVERDOSAGE The clinical consequences of overdosing with Technetium Tc 99m Sulfur Colloid Injection are not known. 11 DESCRIPTION Kit for the Preparation of Technetium Tc 99m Sulfur Colloid Injection contains a multi-dose Reaction Vial, a Solution A vial and a Solution B vial which contain the sterile non-pyrogenic, non-radioactive ingredients necessary to produce Technetium Tc 99m Sulfur Colloid Injection for diagnostic use by subcutaneous, intraperitoneal, or intravenous injection or by oral administration. Each 10 mL multi-dose Reaction Vial contains, in lyophilized form 2 mg sodium thiosulfate anhydrous, 2.3 mg edetate disodium and 18.1 mg bovine gelatin; a Solution A vial contains 1.8 mL of 0.148 N hydrochloric acid solution and a Solution B vial contains 1.8 mL aqueous solution of 24.6 mg/mL sodium biphosphate anhydrous and 7.9 mg/mL sodium hydroxide. When a solution of sterile and non-pyrogenic Sodium Pertechnetate Tc 99m Injection in isotonic saline is mixed with these components, following the instructions provided with the kit, Technetium Tc 99m Sulfur Colloid Injection is formed. The product is intended for subcutaneous, intraperitoneal, or intravenous injection or for oral administration. The precise structure of Technetium Tc 99m Sulfur Colloid Injection is not known at this time. 11.1 Physical Characteristics Technetium Tc 99m decays by isomeric transition with a physical half-life of 6.02 hours.4 The principal photon that is useful for detection and imaging studies is listed in Table 7.

DOE/TIC-11026: 108, 11.2 External Radiation The specific gamma ray constant for Tc 99m is 0.78 R/millicurie-hr at 1cm. The first half-value layer is 0.017 cm of lead (Pb). A range of values for the relative attenuation of the radiation emitted by this radionuclide that results from interposition of various thicknesses of Pb is shown in Table 8. For example, the use of a 0.25 cm thickness of Pb will attenuate the radiation emitted by a factor of about 1,000. Page 7 Reference ID: 3173576 1981 This label may not be the latest approved by FDA.

[see Description (11.1)] Following subcutaneous injection, Technetium Tc 99m Sulfur Colloid enters the lymphatic capillaries and is transported with lymph to lymph nodes. However, when there is massive nodal metastatic involvement, the normal transport to lymph nodes is lost because few normal cells remain in the node. [see Dosage and Administration (2.4)] Following intraperitoneal injection, Technetium Tc 99m Sulfur Colloid mixes with the peritoneal fluid; rate of clearance from the cavity allows assessment of the patency of the shunt. Clearance varies from insignificant, which may occur with complete shunt blockage, to very rapid clearance with subsequent transfer into the systemic circulation when the shunt is patent. Following intravenous injection, Technetium Tc 99m Sulfur Colloid is taken up by the reticuloendothelial system (RES), allowing RES rich structures to be imaged. With oral administration, Technetium Tc 99m Sulfur Colloid is not absorbed accounting for its function in esophageal transit studies, gastroesophageal reflux scintigraphy, and for the detection of pulmonary aspiration of gastric contents. 12.3 Pharmacokinetics Following intravenous administration, Technetium Tc 99m Sulfur Colloid Injection is rapidly cleared from the blood by the reticuloendothelial system with a nominal half-life of approximately 2 1/2 minutes. Uptake of the radioactive colloid by organs of the RES is dependent upon both their relative blood flow rates and the functional capacity of the phagocytic cells. In the average patient 80 to 90% of the injected colloidal particles are phagocytized by the Kupffer cells of the liver, 5 to 10% by the spleen and the balance by the bone marrow. Following oral ingestion, Technetium Tc 99m Sulfur Colloid is distributed primarily through the gastrointestinal tract with elimination primarily through the feces. 13 NONCLINICAL TOXICOLOGY 13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility Animal studies to evaluate the carcinogenicity, mutagenesis, or reproductive toxicity potentials of Technetium Tc 99m Sulfur Colloid have not been conducted.

From these publications, 15 studies were identified for inclusion within a meta-analysis, based upon the following criteria: prospective design, minimum number of 50 lymph node localization procedures, and paired outcome data available for both Technetium Tc 99m Sulfur Colloid Injection and blue dye. Within these studies, the number of procedures ranged from 62 to 6,197; in general one procedure involved a single patient but in some uncommon situations, one patient underwent more than one procedure. The patients received subcutaneous Technetium Tc 99m Sulfur Colloid Injection doses ranging between 0.1 and 2 mCi. The mean age of patients ranged from 52 to 60 years, and almost all were female. Lymph nodes that contained radioactivity were generally localized based upon increased counts, in comparison to a background threshold (e.g., nodes containing a minimum of radioactive counts 3 times higher than background or containing at least 10 fold higher counts than contiguous nodes). Radioactivity was measured using a handheld gamma counter. Table 10 shows the tracer localization rates where the tracer localization rate (%) is defined as the percentage of procedures which had at least one lymph node containing the specific tracer. Random effect meta-analytic measures were used for estimating various rates of tracer localization by procedure along with the respective confidence intervals. The random effect meta-analytical methods take into account the sample size of each study as well as within and between study variability. In general, most procedures involved the resection of lymph nodes in which a tracer had localized to at least one node. However, in some procedures (estimated at approximately 3.4%) neither tracer was localized to a resected lymph node. The reports were insufficient to establish the basis for failed tracer localization. [see Dosage and Administration (2.4)] Table 10.

In some of the publications, different methods of Technetium Tc 99m Sulfur Colloid Injection administration were compared: intradermal (ID), subareolar (SA) and intraparenchymal (IP) methods. Generally, more favorable results were seen using the ID and SA routes, with less favorable results reported when surgeons used the IP method. 14.2 Tracer Localization to Lymph Nodes in Malignant Melanoma A systematic review of eight publications examined the use of Technetium Tc 99m Sulfur Colloid and a blue dye (tracers) to assist surgeons in the localization of lymph nodes among patients with malignant melanoma. A meta-analysis was performed using data from the studies that reported the resected lymph node content of Technetium Tc 99m Sulfur Colloid Injection and blue dye. Four of the eight publications met this criterion and were included in the meta-analysis. Within these four studies, the number of reported patients ranged from 12 to 94. The patients received subcutaneous Technetium Tc 99m Sulfur Colloid Injection doses ranging between 0.25 to 2 mCi. The patients were aged 15 to 89 years and most (53 to 70%) were male. Lymph nodes that contained radioactivity were generally localized based upon increased counts, in comparison to a background threshold (e.g., nodes containing a minimum of radioactive counts 3 times higher than background). Radioactivity was measured using a handheld gamma counter. Table 11 shows the tracer localization rates where the tracer localization rate (%) is defined as the percentage of patients who had at least one lymph node containing the specific tracer. Random effect meta-analytic measures were used for estimating the various rates of tracer localization by patient along with the respective confidence intervals. The random effect meta-analytical methods take into account the sample size of each study as well as within and between study variability. In general, most patients had resected lymph nodes that contained at least one of the tracers. However, in some patients (estimated at approximately 1.6%) neither tracer was localized to a resected lymph node. The reports were insufficient to establish the basis for failed tracer localization.

REGLAN Injection (metoclopramide injection, USP) Rx only WARNING: TARDIVE DYSKINESIA Treatment with metoclopramide can cause tardive dyskinesia, a serious movement disorder that is often irreversible. The risk of developing tardive dyskinesia increases with duration of treatment and total cumulative dose. Metoclopramide therapy should be discontinued in patients who develop signs or symptoms of tardive dyskinesia. There is no known treatment for tardive dyskinesia. In some patients, symptoms may lessen or resolve after metoclopramide treatment is stopped. Treatment with metoclopramide for longer than 12 weeks should be avoided in all but rare cases where therapeutic benefit is thought to outweigh the risk of developing tardive dyskinesia. See WARNINGS. DESCRIPTION Metoclopramide hydrochloride is a white crystalline, odorless substance, freely soluble in water. Chemically, it is 4-amino-5-chloro-N-[2-(diethylamino)ethyl]-2-methoxy benzamide monohydrochloride monohydrate. Molecular weight: 354.3. Structural Formula C14H22ClN3O2•HCl•H2O REGLAN Injection (metoclopramide injection, USP) is a clear, colorless, sterile solution with a pH of 4.5-6.5 for intravenous (IV) or intramuscular (IM) administration. This product is light sensitive. It should be inspected before use and discarded if either color or particulate is observed. 2 mL single dose vials; 10 mL and 30 mL single dose vials Each 1 mL contains: Metoclopramide base 5 mg (as the monohydrochloride monohydrate), Sodium Chloride, USP 8.5 mg, Water for Injection, USP q.s. pH adjusted, when necessary, with 1 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda hydrochloric acid and/or sodium hydroxide. CLINICAL PHARMACOLOGY Metoclopramide stimulates motility of the upper gastrointestinal tract without stimulating gastric, biliary, or pancreatic secretions. Its mode of action is unclear. It seems to sensitize tissues to the action of acetylcholine. The effect of metoclopramide on motility is not dependent on intact vagal innervation, but it can be abolished by anticholinergic drugs. Metoclopramide increases the tone and amplitude of gastric (especially antral) contractions, relaxes the pyloric sphincter and the duodenal bulb, and increases peristalsis of the duodenum and jejunum resulting in accelerated gastric emptying and intestinal transit. It increases the resting tone of the lower esophageal sphincter. It has little, if any, effect on the motility of the colon or gallbladder. In patients with gastroesophageal reflux and low LESP (lower esophageal sphincter pressure), single oral doses of metoclopramide produce dose-related increases in LESP. Effects begin at about 5 mg and increase through 20 mg (the largest dose tested). The increase in LESP from a 5 mg dose lasts about 45 minutes and that of 20 mg lasts between 2 and 3 hours. Increased rate of stomach emptying has been observed with single oral doses of 10 mg. The antiemetic properties of metoclopramide appear to be a result of its antagonism of central and peripheral dopamine receptors. Dopamine produces nausea and vomiting by stimulation of the medullary chemoreceptor trigger zone (CTZ), and metoclopramide blocks stimulation of the CTZ by agents like l-dopa or apomorphine which are known to increase dopamine levels or to possess dopamine-like effects. Metoclopramide also abolishes the slowing of gastric emptying caused by apomorphine. Like the phenothiazines and related drugs, which are also dopamine antagonists, metoclopramide produces sedation and may produce extrapyramidal reactions, although these are comparatively rare (see WARNINGS). Metoclopramide inhibits the central and peripheral effects of apomorphine, induces release of prolactin and causes a transient increase in circulating aldosterone levels, which may be associated with transient fluid retention. The onset of pharmacological action of metoclopramide is 1 to 3 minutes following an intravenous dose, 10 to 15 minutes following intramuscular administration, and 30 to 60 minutes following an oral dose; pharmacological effects persist for 1 to 2 hours. Pharmacokinetics Metoclopramide is rapidly and well absorbed. Relative to an intravenous dose of 20 mg, the absolute oral bioavailability of metoclopramide is 80% ± 15.5% as demonstrated in a crossover study of 18 subjects. Peak plasma concentrations occur at about 1-2 hr after a single oral dose. Similar time to peak is observed after individual doses at steady state. In a single dose study of 12 subjects, the area under the drug concentration-time curve increases linearly with doses from 20 to 100 mg. Peak concentrations increase linearly with dose; time to peak concentrations remains the same; whole body clearance is unchanged; and the elimination rate remains the same. The average elimination half-life in individuals with normal renal function is 5-6 hr. Linear kinetic processes adequately describe the absorption and elimination of 2 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda metoclopramide. Approximately 85% of the radioactivity of an orally administered dose appears in the urine within 72 hr. Of the 85% eliminated in the urine, about half is present as free or conjugated metoclopramide. The drug is not extensively bound to plasma proteins (about 30%). The whole body volume of distribution is high (about 3.5 L/kg) which suggests extensive distribution of drug to the tissues. Renal impairment affects the clearance of metoclopramide. In a study with patients with varying degrees of renal impairment, a reduction in creatinine clearance was correlated with a reduction in plasma clearance, renal clearance, non-renal clearance, and increase in elimination half-life. The kinetics of metoclopramide in the presence of renal impairment remained linear however. The reduction in clearance as a result of renal impairment suggests that adjustment downward of maintenance dosage should be done to avoid drug accumulation. Adult Pharmacokinetic Data Parameter Value Vd (L/kg) ~ 3.5 Plasma Protein Binding ~ 30% t1/2 (hr) 5-6 Oral Bioavailability 80%±15.5% In pediatric patients, the pharmacodynamics of metoclopramide following oral and intravenous administration are highly variable and a concentration-effect relationship has not been established. There are insufficient reliable data to conclude whether the pharmacokinetics of metoclopramide in adults and the pediatric population are similar. Although there are insufficient data to support the efficacy of metoclopramide in pediatric patients with symptomatic gastroesophageal reflux (GER) or cancer chemotherapy-related nausea and vomiting, its pharmacokinetics have been studied in these patient populations. In an open-label study, six pediatric patients (age range, 3.5 weeks to 5.4 months) with GER received a metoclopramide 0.15 mg/kg oral solution every 6 hours for 10 doses. The mean peak plasma concentration of metoclopramide after the tenth dose was 2-fold (56.8 μg/L) higher compared to that observed after the first dose (29 μg/L) indicating drug accumulation with repeated dosing. After the tenth dose, the mean time to reach peak concentrations (2.2 hr), half- life (4.1 hr), clearance (0.67 L/h/kg), and volume of distribution (4.4 L/kg) of metoclopramide were similar to those observed after the first dose. In the youngest patient (age, 3.5 weeks), metoclopramide half-life after the first and the tenth dose (23.1 and 10.3 hr, respectively) was significantly longer compared to other infants due to reduced clearance. This may be attributed to immature hepatic and renal systems at birth. Single intravenous doses of metoclopramide 0.22 to 0.46 mg/kg (mean, 0.35 mg/kg) were administered over 5 minutes to 9 pediatric cancer patients receiving chemotherapy (mean age, 11.7 years; range, 7 to 14 yr) for prophylaxis of cytotoxic-induced vomiting. The metoclopramide plasma concentrations extrapolated to time zero ranged from 65 to 395 μg/L 3 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda (mean, 152 μg/L). The mean elimination half-life, clearance, and volume of distribution of metoclopramide were 4.4 hr (range, 1.7 to 8.3 hr), 0.56 L/h/kg (range, 0.12 to 1.20 L/h/kg), and 3.0 L/kg (range, 1.0 to 4.8 L/kg), respectively. In another study, nine pediatric cancer patients (age range, 1 to 9 yr) received 4 to 5 intravenous infusions (over 30 minutes) of metoclopramide at a dose of 2 mg/kg to control emesis. After the last dose, the peak serum concentrations of metoclopramide ranged from 1060 to 5680 μg/L. The mean elimination half-life, clearance, and volume of distribution of metoclopramide were 4.5 hr (range, 2.0 to 12.5 hr), 0.37 L/h/kg (range, 0.10 to 1.24 L/h/kg), and 1.93 L/kg (range, 0.95 to 5.50 L/kg), respectively.

INDICATIONS AND USAGE Diabetic Gastroparesis (Diabetic Gastric Stasis) REGLAN (metoclopramide hydrochloride, USP) is indicated for the relief of symptoms associated with acute and recurrent diabetic gastric stasis. The Prevention of Nausea and Vomiting Associated with Emetogenic Cancer Chemotherapy REGLAN Injection is indicated for the prophylaxis of vomiting associated with emetogenic cancer chemotherapy. The Prevention of Postoperative Nausea and Vomiting REGLAN Injection is indicated for the prophylaxis of postoperative nausea and vomiting in those circumstances where nasogastric suction is undesirable. Small Bowel Intubation REGLAN Injection may be used to facilitate small bowel intubation in adults and pediatric patients in whom the tube does not pass the pylorus with conventional maneuvers. Radiological Examination REGLAN Injection may be used to stimulate gastric emptying and intestinal transit of barium in 4 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda cases where delayed emptying interferes with radiological examination of the stomach and/or small intestine. CONTRAINDICATIONS Metoclopramide should not be used whenever stimulation of gastrointestinal motility might be dangerous, e.g., in the presence of gastrointestinal hemorrhage, mechanical obstruction, or perforation. Metoclopramide is contraindicated in patients with pheochromocytoma because the drug may cause a hypertensive crisis, probably due to release of catecholamines from the tumor. Such hypertensive crises may be controlled by phentolamine. Metoclopramide is contraindicated in patients with known sensitivity or intolerance to the drug. Metoclopramide should not be used in epileptics or patients receiving other drugs which are likely to cause extrapyramidal reactions, since the frequency and severity of seizures or extrapyramidal reactions may be increased. WARNINGS Neuroleptic Malignant Syndrome (NMS) There have been rare reports of an uncommon but potentially fatal symptom complex sometimes referred to as Neuroleptic Malignant Syndrome (NMS) associated with metoclopramide. Clinical manifestations of NMS include hyperthermia, muscle rigidity, altered consciousness, and evidence of autonomic instability (irregular pulse or blood pressure, tachycardia, diaphoresis and cardiac arrhythmias). The diagnostic evaluation of patients with this syndrome is complicated. In arriving at a diagnosis, it is important to identify cases where the clinical presentation includes both serious medical illness (e.g., pneumonia, systemic infection, etc.) and untreated or inadequately treated extrapyramidal signs and symptoms (EPS). Other important considerations in the differential diagnosis include central anticholinergic toxicity, heat stroke, malignant hyperthermia, drug fever and primary central nervous system (CNS) pathology. The management of NMS should include 1) immediate discontinuation of metoclopramide and other drugs not essential to concurrent therapy, 2) intensive symptomatic treatment and medical monitoring, and 3) treatment of any concomitant serious medical problems for which specific treatments are available. Bromocriptine and dantrolene sodium have been used in treatment of NMS, but their effectiveness have not been established (see ADVERSE REACTIONS). Extrapyramidal Symptoms (EPS) Acute Dystonic Reactions Acute dystonic reactions occur in approximately 1 in 500 patients treated with the usual adult dosages of 30-40 mg/day of metoclopramide. These usually are seen during the first 24-48 hours of treatment with metoclopramide, occur more frequently in pediatric patients and adult patients less than 30 years of age and are even more frequent at the higher doses used in prophylaxis of vomiting due to cancer chemotherapy. These symptoms may include involuntary movements of limbs and facial grimacing, torticollis, oculogyric crisis, rhythmic protrusion of tongue, bulbar 5 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda type of speech, trismus, or dystonic reactions resembling tetanus. Rarely, dystonic reactions may present as stridor and dyspnea, possibly due to laryngospasm. If these symptoms should occur, inject 50 mg Benadryl® (diphenhydramine hydrochloride) intramuscularly, and they usually will subside. Cogentin® (benztropine mesylate), 1 to 2 mg intramuscularly, may also be used to reverse these reactions. Tardive Dyskinesia (see Boxed Warnings) Treatment with metoclopramide can cause tardive dyskinesia (TD), a potentially irreversible and disfiguring disorder characterized by involuntary movements of the face, tongue, or extremities. Although the risk of TD with metoclopramide has not been extensively studied, one published study reported a TD prevalence of 20% among patients treated for at least 12 weeks. Treatment with metoclopramide for longer than 12 weeks should be avoided in all but rare cases where therapeutic benefit is thought to outweigh the risk of developing TD. Although the risk of developing TD in the general population may be increased among the elderly, women, and diabetics, it is not possible to predict which patients will develop metoclopramide-induced TD. Both the risk of developing TD and the likelihood that TD will become irreversible increase with duration of treatment and total cumulative dose. Metoclopramide should be discontinued in patients who develop signs or symptoms of TD. There is no known effective treatment for established cases of TD, although in some patients, TD may remit, partially or completely, within several weeks to months after metoclopramide is withdrawn. Metoclopramide itself may suppress, or partially suppress, the signs of TD, thereby masking the underlying disease process. The effect of this symptomatic suppression upon the long-term course of TD is unknown. Therefore, metoclopramide should not be used for the symptomatic control of TD. Parkinsonian-like Symptoms Parkinsonian-like symptoms, including bradykinesia, tremor, cogwheel rigidity, or mask-like facies, have occurred more commonly within the first 6 months after beginning treatment with metoclopramide, but occasionally after longer periods. These symptoms generally subside within 2-3 months following discontinuance of metoclopramide. Patients with preexisting Parkinson’s disease should be given metoclopramide cautiously, if at all, since such patients may experience exacerbation of parkinsonian symptoms when taking metoclopramide. Depression Mental depression has occurred in patients with and without prior history of depression. Symptoms have ranged from mild to severe and have included suicidal ideation and suicide. Metoclopramide should be given to patients with a prior history of depression only if the expected benefits outweigh the potential risks. 6 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda PRECAUTIONS General In one study in hypertensive patients, intravenously administered metoclopramide was shown to release catecholamines; hence, caution should be exercised when metoclopramide is used in patients with hypertension. Intravenous injections of undiluted metoclopramide should be made slowly allowing 1 to 2 minutes for 10 mg since a transient but intense feeling of anxiety and restlessness, followed by drowsiness, may occur with rapid administration. Because metoclopramide produces a transient increase in plasma aldosterone, certain patients, especially those with cirrhosis or congestive heart failure, may be at risk of developing fluid retention and volume overload. If these side effects occur at any time during metoclopramide therapy, the drug should be discontinued. Intravenous administration of REGLAN Injection diluted in a parenteral solution should be made slowly over a period of not less than 15 minutes. Giving a promotility drug such as metoclopramide theoretically could put increased pressure on suture lines following a gut anastomosis or closure. This possibility should be considered and weighed when deciding whether to use metoclopramide or nasogastric suction in the prevention of postoperative nausea and vomiting. Information for Patients A patient Medication Guide is available for REGLAN Injection. The prescriber or health professional should instruct patients, their families, and their caregivers to read the Medication Guide and should assist them in understanding its contents. Patients should be given the opportunity to discuss the contents of the Medication Guide and to obtain answers to any questions they may have. The complete text of the Medication Guide is printed at the end of this document. Metoclopramide may impair the mental and/or physical abilities required for the performance of hazardous tasks such as operating machinery or driving a motor vehicle. The ambulatory patient should be cautioned accordingly. Drug Interactions The effects of metoclopramide on gastrointestinal motility are antagonized by anticholinergic drugs and narcotic analgesics. Additive sedative effects can occur when metoclopramide is given with alcohol, sedatives, hypnotics, narcotics, or tranquilizers. The finding that metoclopramide releases catecholamines in patients with essential hypertension suggests that it should be used cautiously, if at all, in patients receiving monoamine oxidase inhibitors. Absorption of drugs from the stomach may be diminished (e.g., digoxin) by metoclopramide, whereas the rate and/or extent of absorption of drugs from the small bowel may be increased 7 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda (e.g., acetaminophen, tetracycline, levodopa, ethanol, cyclosporine). Gastroparesis (gastric stasis) may be responsible for poor diabetic control in some patients. Exogenously administered insulin may begin to act before food has left the stomach and lead to hypoglycemia. Because the action of metoclopramide will influence the delivery of food to the intestines and thus the rate of absorption, insulin dosage or timing of dosage may require adjustment. Carcinogenesis, Mutagenesis, Impairment of Fertility A 77-week study was conducted in rats with oral doses up to about 40 times the maximum recommended human daily dose. Metoclopramide elevates prolactin levels and the elevation persists during chronic administration. Tissue culture experiments indicate that approximately one-third of human breast cancers are prolactin-dependent in vitro, a factor of potential importance if the prescription of metoclopramide is contemplated in a patient with previously detected breast cancer. Although disturbances such as galactorrhea, amenorrhea, gynecomastia, and impotence have been reported with prolactin-elevating drugs, the clinical significance of elevated serum prolactin levels is unknown for most patients. An increase in mammary neoplasms has been found in rodents after chronic administration of prolactin-stimulating neuroleptic drugs and metoclopramide. Neither clinical studies nor epidemiologic studies conducted to date, however, have shown an association between chronic administration of these drugs and mammary tumorigenesis; the available evidence is too limited to be conclusive at this time. An Ames mutagenicity test performed on metoclopramide was negative. Pregnancy Category B Reproduction studies performed in rats, mice and rabbits by the IM, IV, subcutaneous (SC), and oral routes at maximum levels ranging from 12 to 250 times the human dose have demonstrated no impairment of fertility or significant harm to the fetus due to metoclopramide. There are, however, no adequate and well-controlled studies in pregnant women. Because animal reproduction studies are not always predictive of human response, this drug should be used during pregnancy only if clearly needed. Nursing Mothers Metoclopramide is excreted in human milk. Caution should be exercised when metoclopramide is administered to a nursing mother. Pediatric Use Safety and effectiveness in pediatric patients have not been established except as stated to facilitate small bowel intubation (see OVERDOSAGE and DOSAGE AND ADMINISTRATION). Care should be exercised in administering metoclopramide to neonates since prolonged clearance may produce excessive serum concentrations (see CLINICAL PHARMACOLOGY — Pharmacokinetics). In addition, neonates have reduced levels of NADH-cytochrome b5 reductase which, in combination with the aforementioned pharmacokinetic factors, make neonates more susceptible to methemoglobinemia (see OVERDOSAGE). 8 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda The safety profile of metoclopramide in adults cannot be extrapolated to pediatric patients. Dystonias and other extrapyramidal reactions associated with metoclopramide are more common in the pediatric population than in adults. (See WARNINGS and ADVERSE REACTIONS — Extrapyramidal Reactions.) Geriatric Use Clinical studies of REGLAN did not include sufficient numbers of subjects aged 65 and over to determine whether elderly subjects respond differently from younger subjects. The risk of developing parkinsonian-like side effects increases with ascending dose. Geriatric patients should receive the lowest dose of REGLAN that is effective. If parkinsonian-like symptoms develop in a geriatric patient receiving REGLAN, REGLAN should generally be discontinued before initiating any specific anti-parkinsonian agents (see WARNINGS). The elderly may be at greater risk for tardive dyskinesia (see WARNINGS - Tardive Dyskinesia). Sedation has been reported in REGLAN users. Sedation may cause confusion and manifest as over-sedation in elderly (see CLINICAL PHARMACOLOGY, PRECAUTIONS – Information for Patients and ADVERSE REACTIONS – CNS Effects). REGLAN is known to be substantially excreted by the kidney, and the risk of toxic reactions to this drug may be greater in patients with impaired renal function (see DOSAGE AND ADMINISTRATION - Use in Patients With Renal or Hepatic Impairment). For these reasons, dose selection for an elderly patient should be cautious, usually starting at the low end of the dosing range, reflecting the greater frequency of decreased renal function, concomitant disease, or other drug therapy in the elderly (see Use in Patients With Renal or Hepatic Impairment). Other Special Populations Patients with NADH-cytochrome b5 reductase deficiency are at an increased risk of developing methemoglobinemia and/or sulfhemoglobinemia when metoclopramide is administered. In patients with G6PD deficiency who experience metoclopramide-induced methemoglobinemia, methylene blue treatment is not recommended (see OVERDOSAGE). ADVERSE REACTIONS In general, the incidence of adverse reactions correlates with the dose and duration of metoclopramide administration. The following reactions have been reported, although in most instances, data do not permit an estimate of frequency: CNS Effects Restlessness, drowsiness, fatigue, and lassitude may occur in patients receiving the recommended prescribed dosage of REGLAN Injection. Insomnia, headache, confusion, dizziness, or mental depression with suicidal ideation also may occur (see WARNINGS). In cancer chemotherapy patients being treated with 1-2 mg/kg per dose, incidence of drowsiness is about 70%. There are isolated reports of convulsive seizures without clear-cut relationship to metoclopramide. Rarely, hallucinations have been reported. 9 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda Extrapyramidal Reactions (EPS) Acute dystonic reactions, the most common type of EPS associated with metoclopramide, occur in approximately 0.2% of patients (1 in 500) treated with 30 to 40 mg of metoclopramide per day. In cancer chemotherapy patients receiving 1-2 mg/kg per dose, the incidence is 2% in patients over the ages of 30-35, and 25% or higher in pediatric patients and adult patients less than 30 years of age who have not had prophylactic administration of diphenhydramine. Symptoms include involuntary movements of limbs, facial grimacing, torticollis, oculogyric crisis, rhythmic protrusion of tongue, bulbar type of speech, trismus, opisthotonus (tetanus-like reactions), and, rarely, stridor and dyspnea possibly due to laryngospasm; ordinarily these symptoms are readily reversed by diphenhydramine (see WARNINGS). Parkinsonian-like symptoms may include bradykinesia, tremor, cogwheel rigidity, mask-like facies (see WARNINGS). Tardive dyskinesia most frequently is characterized by involuntary movements of the tongue, face, mouth, or jaw, and sometimes by involuntary movements of the trunk and/or extremities; movements may be choreoathetotic in appearance (see WARNINGS). Motor restlessness (akathisia) may consist of feelings of anxiety, agitation, jitteriness, and insomnia, as well as inability to sit still, pacing, foot tapping. These symptoms may disappear spontaneously or respond to a reduction in dosage. Neuroleptic Malignant Syndrome Rare occurrences of neuroleptic malignant syndrome (NMS) have been reported. This potentially fatal syndrome is comprised of the symptom complex of hyperthermia, muscular rigidity, altered consciousness, and autonomic instability (see WARNINGS). Endocrine Disturbances Galactorrhea, amenorrhea, gynecomastia, impotence secondary to hyperprolactinemia (see PRECAUTIONS). Fluid retention secondary to transient elevation of aldosterone (see CLINICAL PHARMACOLOGY). Cardiovascular Hypotension, hypertension, supraventricular tachycardia, bradycardia, fluid retention, acute congestive heart failure and possible atrioventricular (AV) block (see CONTRAINDICATIONS and PRECAUTIONS). Gastrointestinal Nausea and bowel disturbances, primarily diarrhea. Hepatic Rarely, cases of hepatotoxicity, characterized by such findings as jaundice and altered liver function tests, when metoclopramide was administered with other drugs with known hepatotoxic potential. Renal Urinary frequency and incontinence. 10 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda Hematologic A few cases of neutropenia, leukopenia, or agranulocytosis, generally without clear-cut relationship to metoclopramide. Methemoglobinemia in adults and especially with overdosage in neonates (see OVERDOSAGE). Sulfhemoglobinemia in adults. Allergic Reactions A few cases of rash, urticaria, or bronchospasm, especially in patients with a history of asthma. Rarely, angioneurotic edema, including glossal or laryngeal edema. Miscellaneous Visual disturbances. Porphyria. Transient flushing of the face and upper body, without alterations in vital signs, following high doses intravenously. OVERDOSAGE Symptoms of overdosage may include drowsiness, disorientation and extrapyramidal reactions. Anticholinergic or antiparkinson drugs or antihistamines with anticholinergic properties may be helpful in controlling the extrapyramidal reactions. Symptoms are self-limiting and usually disappear within 24 hours. Hemodialysis removes relatively little metoclopramide, probably because of the small amount of the drug in blood relative to tissues. Similarly, continuous ambulatory peritoneal dialysis does not remove significant amounts of drug. It is unlikely that dosage would need to be adjusted to compensate for losses through dialysis. Dialysis is not likely to be an effective method of drug removal in overdose situations. Unintentional overdose due to misadministration has been reported in infants and children with the use of REGLAN syrup. While there was no consistent pattern to the reports associated with these overdoses, events included seizures, extrapyramidal reactions, and lethargy. Methemoglobinemia has occurred in premature and full-term neonates who were given overdoses of metoclopramide (1-4 mg/kg/day orally, intramuscularly or intravenously for 1-3 or more days). Methemoglobinemia can be reversed by the intravenous administration of methylene blue. However, methylene blue may cause hemolytic anemia in patients with G6PD deficiency, which may be fatal (see PRECAUTIONS – Other Special Populations). DOSAGE AND ADMINISTRATION For the Relief of Symptoms Associated with Diabetic Gastroparesis (Diabetic Gastric Stasis) If only the earliest manifestations of diabetic gastric stasis are present, oral administration of metoclopramide may be initiated. However, if severe symptoms are present, therapy should begin with REGLAN Injection (IM or IV). Doses of 10 mg may be administered slowly by the intravenous route over a 1- to 2-minute period. Administration of REGLAN Injection (metoclopramide injection, USP) up to 10 days may be required before symptoms subside, at which time oral administration of metoclopramide may be instituted. The physician should make a thorough assessment of the risks and benefits prior to 11 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda prescribing further metoclopramide treatment. For the Prevention of Nausea and Vomiting Associated with Emetogenic Cancer Chemotherapy Intravenous infusions should be made slowly over a period of not less than 15 minutes, 30 minutes before beginning cancer chemotherapy and repeated every 2 hours for two doses, then every 3 hours for three doses. The initial two doses should be 2 mg/kg if highly emetogenic drugs such as cisplatin or dacarbazine are used alone or in combination. For less emetogenic regimens, 1 mg/kg per dose may be adequate. For doses in excess of 10 mg, REGLAN Injection should be diluted in 50 mL of a parenteral solution. The preferred parenteral solution is Sodium Chloride Injection (normal saline), which when combined with REGLAN Injection, can be stored frozen for up to 4 weeks. REGLAN Injection is degraded when admixed and frozen with Dextrose-5% in Water. REGLAN Injection diluted in Sodium Chloride Injection, Dextrose-5% in Water, Dextrose-5% in 0.45% Sodium Chloride, Ringer’s Injection, or Lactated Ringer’s Injection may be stored up to 48 hours (without freezing) after preparation if protected from light. All dilutions may be stored unprotected from light under normal light conditions up to 24 hours after preparation. If acute dystonic reactions should occur, inject 50 mg Benadryl® (diphenhydramine hydrochloride) intramuscularly, and the symptoms usually will subside. For the Prevention of Postoperative Nausea and Vomiting REGLAN Injection should be given intramuscularly near the end of surgery. The usual adult dose is 10 mg; however, doses of 20 mg may be used. To Facilitate Small Bowel Intubation If the tube has not passed the pylorus with conventional maneuvers in 10 minutes, a single dose (undiluted) may be administered slowly by the intravenous route over a 1- to 2-minute period. The recommended single dose is: Pediatric patients above 14 years of age and adults — 10 mg metoclopramide base. Pediatric patients (6-14 years of age) — 2.5 to 5 mg metoclopramide base; (under 6 years of age) — 0.1 mg/kg metoclopramide base. To Aid in Radiological Examinations In patients where delayed gastric emptying interferes with radiological examination of the stomach and/or small intestine, a single dose may be administered slowly by the intravenous route over a 1- to 2-minute period. For dosage, see intubation above. Use in Patients With Renal or Hepatic Impairment Since metoclopramide is excreted principally through the kidneys, in those patients whose creatinine clearance is below 40 mL/min, therapy should be initiated at approximately one-half the recommended dosage. Depending upon clinical efficacy and safety considerations, the 12 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda dosage may be increased or decreased as appropriate. See OVERDOSAGE section for information regarding dialysis. Metoclopramide undergoes minimal hepatic metabolism, except for simple conjugation. Its safe use has been described in patients with advanced liver disease whose renal function was normal. NOTE: Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration, whenever solution and container permit.

For current labeling information, please visit https://www.fda.gov/drugsatfda MEDICATION GUIDE REGLAN (Reg-lan) (metoclopramide) injection You or your caregiver should read the Medication Guide before you start receiving REGLAN injection and before you get another dose of REGLAN injection. There may be new information. If you take another product that contains metoclopramide (such as REGLAN tablets, REGLAN ODT, or metoclopramide oral syrup), you should read the Medication Guide that comes with that product. Some of the information may be different. This Medication Guide does not take the place of talking to your doctor about your medical condition or your treatment. What is the most important information I should know about REGLAN? REGLAN can cause serious side effects, including: Abnormal muscle movements called tardive dyskinesia (TD). These movements happen mostly in the face muscles. You can not control these movements. They may not go away even after stopping REGLAN. There is no treatment for TD, but symptoms may lessen or go away over time after you stop taking REGLAN. Your chances for getting TD go up: • the longer you take REGLAN and the more REGLAN you take. You should not take REGLAN for more than 12 weeks. • if you are older, especially if you are a woman • if you have diabetes It is not possible for your doctor to know if you will get TD if you take REGLAN. Call your doctor right away if you get movements you can not stop or control, such as: • lip smacking, chewing, or puckering up your mouth • frowning or scowling • sticking out your tongue • blinking and moving your eyes • shaking of your arms and legs See the section “What are the possible side effects of REGLAN?” for more information about side effects. What is REGLAN? REGLAN is a prescription medicine used to: • relieve symptoms of slow stomach emptying in people with diabetes 1 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda • prevent nausea and vomiting that can happen with cancer chemotherapy • prevent nausea and vomiting that may happen after surgery, if your doctor decides that you should not be treated with a stomach tube and suction • help make it easier to insert a tube into the small intestine in both adults and children, if the tube does not pass into the stomach normally. • to help empty stomach contents or to help barium move through your intestine, when you get an X-ray examination of the stomach or small intestine. It is not known if REGLAN is safe and works in children except when used to help insert a tube into the small intestine. Who should not receive REGLAN? Do not receive REGLAN if you: • have stomach or intestine problems that could get worse with REGLAN, such as bleeding, blockage or a tear in your stomach or bowel wall • have an adrenal gland tumor called pheochromocytoma • are allergic to REGLAN or anything in it. See the end of this Medication Guide for a list of ingredients in REGLAN. • take medicines that can cause uncontrolled movements, such as medicines for mental illness • have seizures What should I tell my doctor before receiving REGLAN? Tell your doctor about all of your medical conditions, including if you have: • depression • Parkinson’s disease • high blood pressure • kidney problems. Your doctor may start with a lower dose. • liver problems or heart failure. REGLAN may cause your body to hold fluids. • diabetes. Your dose of insulin may need to be changed. • breast cancer • you are pregnant or plan to become pregnant. It is not known if REGLAN will harm your unborn child. • you are breastfeeding. REGLAN is passed into human milk and may harm your baby. Talk with your doctor about the best way to feed your baby if you take REGLAN. Tell your doctor about all the medicines you take, including prescription and non­ prescription medicines, vitamins and herbal supplements. REGLAN and some other medicines can affect each other and may not work as well, or cause possible side effects. Do not start any new medicines while receiving REGLAN until you talk with your doctor. 2 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda Especially tell your doctor if you take: • another medicine that contains metoclopramide, such as REGLAN tablets, REGLAN ODT, or metoclopramide oral syrup • a blood pressure medicine • a medicine for depression, especially a Monoamine Oxidase Inhibitor (MAOI) • insulin • a medicine that can make you sleepy, such as anti-anxiety medicine, sleep medicines, and narcotics. If you are not sure if your medicine is one listed above, ask your doctor or pharmacist. Know the medicines you take. Keep a list of them and show it to your doctor and pharmacist when you get a new medicine. How will I receive REGLAN? • REGLAN will be given to you by intravenous (IV) infusion into your vein or by intramuscular (IM) injection into a large muscle. Where and how you receive your REGLAN injection (IV or IM) will depend on why you are receiving it. • Certain side effects can happen if REGLAN is given too fast. See the section “What are the possible side effects of REGLAN?” • You should not take or receive REGLAN for more than 12 weeks. What should I avoid while receiving REGLAN? • Do not drink alcohol while receiving REGLAN. Alcohol may make some side effects of REGLAN worse, such as feeling sleepy. • Do not drive, work with machines, or do dangerous tasks until you know how REGLAN affects you. REGLAN may cause sleepiness. What are the possible side effects of REGLAN? REGLAN can cause serious side effects, including: • Abnormal muscle movements. See the section “What is the most important information I should know about REGLAN?” • Uncontrolled spasms of your face and neck muscles, or muscles of your body, arms, and legs (dystonia). These muscle spasms can cause abnormal movements and body positions. These spasms usually start within the first 2 days of treatment. These spasms happen more often in children and adults under age 30. • Depression, thoughts about suicide, and suicide. Some people who take REGLAN become depressed. You may have thoughts about hurting or killing yourself. Some people who take REGLAN have ended their own lives (suicide). • Neuroleptic Malignant Syndrome (NMS). NMS is a very rare but very serious condition that can happen with REGLAN. NMS can cause death and must be 3 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda treated in a hospital. Symptoms of NMS include: high fever, stiff muscles, problems thinking, very fast or uneven heartbeat, and increased sweating. • Parkinsonism. Symptoms include slight shaking, body stiffness, trouble moving or keeping your balance. If you already have Parkinson’s disease, your symptoms may become worse while you are receiving REGLAN. Call your doctor and get medical help right away if you: • feel depressed or have thoughts about hurting or killing yourself • have high fever, stiff muscles, problems thinking, very fast or uneven heartbeat, and increased sweating • have muscle movements you can not stop or control • have muscle movements that are new or unusual Common side effects of REGLAN include: • feeling restless, sleepy, tired, dizzy, or exhausted • headache • confusion • trouble sleeping Infusion related side effects can happen if REGLAN is given too fast. You may feel very anxious and restless for a short time, and then become sleepy while you are receiving a dose of REGLAN. Tell your doctor or nurse right away if this happens. You may have more side effects the longer you take REGLAN and the more REGLAN you take. Tell your doctor about any side effects that bother you or do not go away.

However, after the Sodium Pertechnetate Tc 99m is added, maintain adequate shielding of the final preparation. Wear waterproof gloves during the preparation procedure. • Do not use Sodium Pertechnetate Tc 99m containing more than 10 micrograms per mL of aluminum ion because a flocculent precipitate may occur and such a precipitate may localize in the lung. • The contents of the kit are sterile and non-pyrogenic. This preparation contains no bacteriostatic preservative. Follow the directions carefully and adhere strictly to aseptic procedures during preparation. Prepare Technetium Tc 99m Sulfur Colloid Injection by the following aseptic procedure: 1. Remove the dark brown plastic cap from the Sulfur Colloid multi-dose Reaction Vial and swab the top of the vial closure with alcohol to sterilize the surface. Complete the radiation label and affix to the vial. Place the vial in an appropriate lead-capped radiation shield labeled and identified. 2. With a sterile shielded syringe, aseptically obtain 1 to 3 mL of a suitable, oxidant-free sterile and non-pyrogenic Sodium Pertechnetate Tc 99m, each milliliter containing a maximum activity of 18,500 MBq (500 mCi). 3. Aseptically add the Sodium Pertechnetate Tc 99m to the vial. 4. Place a lead cover on the vial shield and dissolve the reagent by gentle swirling. 5. Just before use, remove the red cap from the Solution A vial and swab the top of the vial closure with alcohol to sterilize the surface. Using a sterile needle and syringe, aseptically withdraw 1.5 mL Solution A from the vial. Aseptically Inject 1.5mL Solution A into the multi-dose Reaction Vial and swirl again. 6. Transfer the multi-dose Reaction Vial from vial shield and place in a vigorously boiling water bath (water bath should be shielded with 1/8” to 1/4” lead) deep enough to cover the entire liquid contents of the vial. Keep the vial in the water bath for five minutes. Page 2 of 10 Reference ID: 2977567 This label may not be the latest approved by FDA.

Visual inspection was performed to identify the blue-labeled nodes and a hand held gamma counter was used to identify nodes concentrating the radiopharmaceutical. Multiple methods were used to detect the concentrated radioactivity within lymph nodes. For example, investigators used thresholds of background radioactivity to localize nodes containing a minimum of radioactive counts 3 times higher than the background or containing at least 10 fold higher counts than contiguous nodes. • Technetium Tc 99m Sulfur Colloid Injection and other tracers may not localize all lymph nodes and the tracers may differ in their extent of lymph node localization. The lymph node localization of Technetium Tc 99m Sulfur Colloid Injection is dependent upon the underlying patency and structure of the lymphatic system, the extent of functional reticuloendothelial cells within lymph nodes and the radiopharmaceutical injection technique. Distortion of the underlying lymphatic system architecture and function by prior surgery, radiation or extensive metastatic disease may result in failure of the radiopharmaceutical and other tracers to localize lymph nodes. The use of Technetium Tc 99m Sulfur Colloid Injection is intended to supplement palpation, visual inspection and other procedures important to lymph node localization. [see Clinical Studies (14)] Peritoneo-venous (LeVeen) shunt setting in adults: Following administration of Technetium Tc 99m Sulfur Colloid Injection into the peritoneal cavity, the radiopharmaceutical mixes with the peritoneal fluid. Clearance from the peritoneal cavity varies from insignificant, which may occur with complete shunt blockage, to very rapid clearance with subsequent transfer into the systemic circulation when the shunt is patent. Following transfer into the systemic circulation, the radiopharmaceutical concentrates within the liver (a target organ). Obtain serial images of both the shunt and liver. An adequate evaluation of the difference between total blockage of the shunt and partial blockage may not be feasible in all cases. Transperitoneal absorption of sulfur colloid into the systemic circulation may occur, but it Page 5 of 10 Reference ID: 2977567 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda occurs slowly. Therefore, the most definitive scintigraphic evaluation of shunt patency will generally be obtained if there is visualization of both the shunt itself and the liver and/or spleen within the first three hours post intraperitoneal injection of the radiopharmaceutical. Imaging areas of functioning reticuloendothelial cells in liver, spleen or bone marrow: Altered biodistribution with lung and soft tissue uptake instead of reticuloendothelial system has been reported after intravenous injection. The size and physical-chemical properties of the sulfur colloid particles formed from the components of the kit may determine the biodistribution of the colloid and its uptake by the reticuloendothelial system. Diseases affecting the reticuloendothelial system may also alter the expected uptake pattern. Gastroesophageal and pulmonary aspiration imaging studies: To facilitate the imaging of gastroesophageal reflux consider administering Sulfur Colloid by nasogastric tube. 3 DOSAGE FORMS AND STRENGTHS Kit for the Preparation of Technetium Tc 99m Sulfur Colloid Injection is supplied in a package that contains 5 kits. All components of a kit are sterile and non-pyrogenic. Each 10mL multi-dose Reaction Vial contains, in lyophilized form, 2 mg sodium thiosulfate anhydrous, 2.3 mg edetate disodium and 18.1 mg bovine gelatin; each Solution A vial contains 1.8 mL 0.148 N hydrochloric acid solution and each Solution B vial contains 1.8 mL aqueous solution of 24.6 mg/mL sodium biphosphate anhydrous and 7.9 mg/mL sodium hydroxide. Included in each 5-kit package are one package insert and 10 radiation labels. 4 CONTRAINDICATIONS None 5 WARNINGS AND PRECAUTIONS 5.1 Anaphylactic reactions Anaphylactic reactions with bronchospasm, hypotension, urticaria and rare fatalities have occurred following intravenously administered Technetium Tc 99m Sulfur Colloid Injection. Have emergency resuscitation equipment and personnel immediately available. 5.2 Radiation Risks Radiation-emitting products, including Technetium Tc 99m Sulfur Colloid Injection, may increase the risk for cancer, especially in pediatric patients. Use the smallest dose necessary for imaging and ensure safe handling to protect the patient and health care worker. [see Dosage and Administration (2.3)]. 5.3 Altered distribution, Accumulation of Tracer in the Lungs Technetium Tc 99m Sulfur Colloid Injection is physically unstable, and the particles will settle with time or with exposure to polyvalent cations. These larger particles are likely to be trapped by the pulmonary capillary bed following intravenous injection and result in non-uniform distribution of radioactivity. Agitate the vial adequately before administration of sulfur colloid to avoid particle aggregation and non-uniform distribution of radioactivity. Discard unused drug after 6 hours from the time of formulation. [see Dosage and Administration (2.2)] 6 ADVERSE REACTIONS The most frequently reported adverse reactions, across all categories of use and routes of administration, include rash, allergic reaction, urticaria, anaphylaxis/anaphylactic shock, and hypotension. Less frequently reported adverse reactions are fatal cardiopulmonary arrest, seizures, dyspnea, bronchospasm, abdominal pain, flushing, nausea, vomiting, itching, fever, chills, perspiration, numbness, and dizziness. Local injection site reactions, including burning, blanching, erythema, sclerosis, swelling, eschar, and scarring, have also been reported. 7 DRUG INTERACTIONS Specific drug-drug interactions have not been studied. 8 USE IN SPECIFIC POPULATIONS 8.1 Pregnancy Pregnancy Category C: There are no adequate or well-controlled studies of Technetium Tc 99m Sulfur Colloid Injection in pregnant women, but Technetium Tc 99m crosses the placenta. Among 14 infants born to pregnant patients exposed to Technetium Tc 99m Sulfur Colloid Injection for lymph node localization, no birth defects were reported following drug exposure. No reproduction and development studies in animals have been performed. Technetium Tc 99m Sulfur Colloid Injection should be given to a pregnant woman only if clearly needed.

For current labeling information, please visit https://www.fda.gov/drugsatfda 8.3 Nursing Mothers Technetium Tc 99m is excreted in human milk during lactation. If nursing, patients should express and discard milk for a minimum of 6 hours after administration of Technetium Tc 99m Sulfur Colloid Injection. Following higher dose procedures [greater than 370 MBq (10 mCi)], patients should minimize close contact with infants for 6 hours after receiving a Technetium Tc 99m Sulfur Colloid Injection. 8.4 Pediatric Use The safety and efficacy of Technetium Tc 99m Sulfur Colloid kit in pediatric patients has been shown for the following indications: liver, spleen, and bone marrow imaging, and gastroesophageal and pulmonary aspiration studies. 8.5 Geriatric Use Clinical studies of Kit for the Preparation of Technetium Tc 99m Sulfur Colloid Injection did not include sufficient numbers of subjects aged 65 and over to determine whether they respond differently from younger subjects. 8.6 Females of Reproductive Potential In females of reproductive potential, imaging procedures with Technetium Tc 99m Sulfur Colloid Injection should be performed within ten days following the onset of menses or a pregnancy test should be performed within 48 hours of the procedure. 10 OVERDOSAGE The clinical consequences of overdosing with Technetium Tc 99m Sulfur Colloid Injection are not known. 11 DESCRIPTION Kit for the Preparation of Technetium Tc 99m Sulfur Colloid Injection contains a multi-dose Reaction Vial, a Solution A vial and a Solution B vial which contain the sterile non-pyrogenic, non-radioactive ingredients necessary to produce Technetium Tc 99m Sulfur Colloid Injection for diagnostic use by subcutaneous, intraperitoneal, or intravenous injection or by oral administration. Each 10 mL multi-dose Reaction Vial contains, in lyophilized form 2 mg sodium thiosulfate anhydrous, 2.3 mg edetate disodium and 18.1 mg bovine gelatin; a Solution A vial contains 1.8 mL of 0.148 N hydrochloric acid solution and a Solution B vial contains 1.8 mL aqueous solution of 24.6 mg/mL sodium biphosphate anhydrous and 7.9 mg/mL sodium hydroxide. When a solution of sterile and non-pyrogenic Sodium Pertechnetate Tc 99m Injection in isotonic saline is mixed with these components, following the instructions provided with the kit, Technetium Tc 99m Sulfur Colloid Injection is formed. The product is intended for subcutaneous, intraperitoneal, or intravenous injection or for oral administration. The precise structure of Technetium Tc 99m Sulfur Colloid Injection is not known at this time. 11.1 Physical Characteristics Technetium Tc 99m decays by isomeric transition with a physical half-life of 6.02 hours.4 The principal photon that is useful for detection and imaging studies is listed in Table 7.

DOE/TIC-11026: 108, 1981 11.2 External Radiation The specific gamma ray constant for Tc 99m is 0.78 R/millicurie-hr at 1cm. The first half-value layer is 0.017 cm of lead (Pb). A range of values for the relative attenuation of the radiation emitted by this radionuclide that results from interposition of various thicknesses of Pb is shown in Table 8. For example, the use of a 0.25 cm thickness of Pb will attenuate the radiation emitted by a factor of about 1,000. Page 7 of 10 Reference ID: 2977567 This label may not be the latest approved by FDA.

However, when there is massive nodal metastatic involvement, the normal transport to lymph nodes is lost because few normal cells remain in the node.[see Dosage and Administration (2.4)] Following intraperitoneal injection, Technetium Tc 99m Sulfur Colloid mixes with the peritoneal fluid; rate of clearance from the cavity allows assessment of the patency of the shunt. Clearance varies from insignificant, which may occur with complete shunt blockage, to very rapid clearance with subsequent transfer into the systemic circulation when the shunt is patent. Following intravenous injection, Technetium Tc 99m Sulfur Colloid is taken up by the reticuloendothelial system (RES), allowing RES rich structures to be imaged. With oral administration, Technetium Tc 99m Sulfur Colloid is not absorbed accounting for its function in esophageal transit studies, gastroesophageal reflux scintigraphy, and for the detection of pulmonary aspiration of gastric contents. 12.3 Pharmacokinetics Following intravenous administration, Technetium Tc 99m Sulfur Colloid Injection is rapidly cleared from the blood by the reticuloendothelial system with a nominal half-life of approximately 2 1/2 minutes. Uptake of the radioactive colloid by organs of the RES is dependent upon both their relative blood flow rates and the functional capacity of the phagocytic cells. In the average patient 80 to 90% of the injected collodial particles are phagocytized by the Kupffer cells of the liver, 5 to 10% by the spleen and the balance by the bone marrow. Following oral ingestion, Technetium Tc 99m Sulfur Colloid is distributed primarily through the gastrointestinal tract with elimination primarily through the feces. 13 NONCLINICAL TOXICOLOGY 13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility No long-term animal studies have been performed to evaluate carcinogenic potential or whether Technetium Tc 99m Sulfur Colloid affects fertility in males or females. Mutagenesis studies have not been conducted. Page 8 of 10 Reference ID: 2977567 This label may not be the latest approved by FDA.

From these publications, 15 studies were identified for inclusion within a meta-analysis, based upon the following criteria: prospective design, minimum number of 50 lymph node localization procedures, and paired outcome data available for both Technetium Tc 99m Sulfur Colloid Injection and blue dye. Within these studies, the number of procedures ranged from 62 to 6,197; in general one procedure involved a single patient but in some uncommon situations, one patient underwent more than one procedure. The patients received subcutaneous Technetium Tc 99m Sulfur Colloid Injection doses ranging between 0.1 and 2 mCi. The mean age of patients ranged from 52 to 60 years, and almost all were female. Lymph nodes that contained radioactivity were generally localized based upon increased counts, in comparison to a background threshold (e.g., nodes containing a minimum of radioactive counts 3 times higher than background or containing at least 10 fold higher counts than contiguous nodes). Radioactivity was measured using a handheld gamma counter. Random effect meta-analytic measures were used for estimating various rates of tracer localization by procedure and respective confidence intervals for blue dye and Technetium Tc 99m Sulfur Colloid Injection. Table 10 summarizes the percentage of procedures in which at least one of the resected lymph nodes contained a tracer (radiopharmaceutical and/or blue dye) as well as the percentage of procedures in which none of the resected nodes contained a tracer. In general, most procedures involved the resection of lymph nodes in which a tracer had localized to at least one node. However, in some procedures (estimated at approximately 3.4%) neither tracer was localized to a resected lymph node. The reports were insufficient to establish the basis for failed tracer localization. [see Dosage and Administration (2.4)] Table 10.

BD = blue dye, SCI = Technetium Tc 99m Sulfur Colloid Injection In some of the publications, different methods of Technetium Tc 99m Sulfur Colloid Injection administration were compared: intradermal (ID), subareolar (SA) and intraparenchymal (IP) methods. Generally, more favorable results were seen using the ID and SA routes, with less favorable results reported when surgeons used the IP method. 15 REFERENCES 1.

For current labeling information, please visit https://www.fda.gov/drugsatfda FULL PRESCRIBING INFORMATION 1 INDICATIONS AND USAGE 1.1 Motion Sickness Transderm Scōp® is indicated in adults for prevention of nausea and vomiting associated with motion sickness. [see Clinical Studies (14.1)] 1.2 Post Operative Nausea and Vomiting (PONV) Transderm Scōp is indicated in adults for prevention of nausea and vomiting associated with recovery from anesthesia and/or opiate analgesia and surgery. [see Clinical Studies (14.2)] 2 DOSAGE AND ADMINISTRATION Each Transderm Scōp patch is formulated to deliver in-vivo approximately 1 mg of scopolamine over 3 days. Only one patch should be worn at any time. Do not cut the patch. The patch should be applied only to the skin in the postauricular (hairless area behind one ear) area. Handling After the patch is applied on the dry skin behind the ear, the hands should be washed thoroughly with soap and water and dried. Upon removal, the patch should be discarded. To prevent any traces of scopolamine from coming into direct contact with the eyes, after administration of the patch, the hands and the application site should be washed thoroughly with soap and water and dried. [see How Supplied/Storage and Handling (16) and Patient Counseling Information (17)] 2.1 Initiation of Therapy Motion Sickness  To prevent the nausea and vomiting associated with motion sickness, one Transderm Scōp patch (formulated to deliver approximately 1 mg of scopolamine over 3 days) should be applied to the hairless area behind one ear at least 4 hours before the antiemetic effect is required. Post Operative Nausea and Vomiting  To prevent post operative nausea and vomiting, one Transderm Scōp patch should be applied the evening before scheduled surgery, except for caesarian section.  For caesarian section surgery, to minimize exposure of the newborn baby to the drug, apply the patch one hour prior to caesarian section. 2.2 Continuation of Therapy Should the patch become displaced, it should be discarded, and a fresh one placed on the hairless area behind the other ear. Motion Sickness If therapy is required for longer than 3 days, the first patch should be removed and a fresh one placed on the hairless area behind the other ear. Post Operative Nausea and Vomiting For perioperative use, the patch should be kept in place for 24 hours following surgery at which time it should be removed and discarded. 3 DOSAGE FORMS AND STRENGTHS The Transderm Scōp system is a tan-colored circular flat patch which contains 1.5 mg of scopolamine base and is formulated to deliver in-vivo approximately 1 mg of scopolamine over 3 days. 4 CONTRAINDICATIONS Transderm Scōp is contraindicated in the following populations:  Patients with angle closure glaucoma. [see Adverse Reactions (6)]  Persons who are hypersensitive to the drug scopolamine or other belladonna alkaloids or to any ingredient or component in the formulation or delivery system. [see Drug Interactions (7) and Description (11)] 5 WARNINGS AND PRECAUTIONS 5.1 Open Angle Glaucoma Patients currently being treated for Open Angle Glaucoma Glaucoma therapy in patients with open angle glaucoma should be monitored and may need to be adjusted during Transderm Scōp use, as the mydriatic effect of scopolamine may cause an increase in intraocular pressure. Reference ID: 3301616 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda Patients should be advised to remove the patch immediately and promptly contact a physician in the event that they experience symptoms of acute angle closure glaucoma (pain and reddening of the eyes, accompanied by dilated pupils). 5.2 Temporary Dilation of the Pupil Scopolamine can cause temporary dilation of the pupils and blurred vision if it comes in contact with the eyes. Patients should be strongly advised to wash their hands thoroughly with soap and water immediately after handling the patch. [see Adverse Reactions (6)] In addition, it is important that used patches be disposed of properly to avoid contact with children or pets. [see How Supplied/Storage and Handling (16)] 5.3 Preexisting Gastrointestinal or Urinary Bladder Obstructions Transderm Scōp should be used with caution in patients with pyloric obstruction or urinary bladder neck obstruction. Caution should be exercised when administering an antiemetic or anticholinergic drug, including Transderm Scōp, to patients suspected of having intestinal obstruction. Patients should be instructed to remove the patch if they develop any difficulties in urinating. [see Adverse Reactions (6)] 5.4 History of Seizures or Psychosis Transderm Scōp should be used with caution in patients with a history of seizures or psychosis since scopolamine can potentially aggravate both disorders. 5.5 Idiosyncratic Reactions Idiosyncratic reactions may occur with ordinary therapeutic doses of scopolamine. The most serious of these that have been reported are: acute psychosis, including confusion, agitation, speech disorder, hallucinations, paranoia, and delusions. [see Adverse Reactions (6)] 5.6 Specific Populations Pediatric A safe and effective dose has not been established in the pediatric population [see Use in Specific Populations (8.4)]. Children are particularly susceptible to the side effects of belladonna alkaloids; including mydriasis, hallucinations, amyblyopia, and drug withdrawal syndrome. Neurologic and psychiatric adverse reactions, such as hallucinations, amblyopia and mydriasis have also been reported when one half or one quarter of a patch has been applied. Elderly Transderm Scōp should be used with caution in the elderly because of the increased likelihood of CNS effects, such as hallucinations, confusion, dizziness and drug withdrawal syndrome. Clinical trials of Transderm Scop did not include sufficient number of subjects aged 65 years and older to determine if they respond differently from younger subjects. [see Use in Specific Populations (8.5)] Renal and Hepatic Impaired Transderm Scōp should be used with caution in individuals with impaired renal or hepatic functions because of the increased likelihood of CNS effects. Transderm Scop has not been studied in these populations. [see Use in Specific Populations (8.6)] 5.7 Safety Hazards Drowsiness Since drowsiness, disorientation, and confusion may occur with the use of scopolamine, patients should be warned of the possibility and cautioned against engaging in activities that require mental alertness, such as driving a motor vehicle or operating dangerous machinery. Disorienting Effects Patients who expect to participate in underwater sports should be cautioned regarding the potentially disorienting effects of scopolamine. [see Patient Counseling Information (17)] 5.8 MRI Skin Burns Skin burns have been reported at the patch site in several patients wearing an aluminized transdermal system during a Magnetic Resonance Imaging scan (MRI). Because Transderm Scōp contains aluminum, it is recommended to remove the system before undergoing an MRI. 6 ADVERSE REACTIONS 6.1 Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in clinical practice. Page 4 of 17 Reference ID: 3301616 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda Motion Sickness In motion sickness clinical studies of Transderm Scōp, the most frequent adverse reaction was dry mouth. This occurred in about two thirds of patients on drug. A less frequent adverse drug reaction was drowsiness, which occurred in less than one sixth of patients on drug. Transient impairment of eye accommodation, including blurred vision and dilation of the pupils, was also observed. Post-Operative Nausea and Vomiting In a total of five clinical studies in which Transderm Scōp was administered perioperatively to a total of 461 patients where safety was assessed, dry mouth was the most frequently reported adverse drug reaction, which occurred in approximately 29% of patients on drug. Dizziness was reported by approximately 12% of patients on drug. Other adverse drug reactions reported from these studies, with a frequency of ≥3% of patients treated with Transderm Scop and with a frequency higher than placebo were, in descending order: somnolence, urinary retention, agitation/restlessness, visual impairment, confusion, mydriasis and pharyngitis (see Table 6.1).

Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or to confirm a definite causal relationship. In worldwide marketing with Transderm Scōp, the following adverse drug reactions were reported by body system. Psychiatric disorders: acute psychosis including: hallucinations disorientation, and paranoia. Nervous system disorders: headache, amnesia, coordination abnormalities, speech disorder, disturbance in attention, restlessness. General disorders and administration site conditions: application site burning. Eye disorders: dry eyes, eye pruritis, angle closure glaucoma, amblyopia, eyelid irritation. Skin and subcutaneous tissue disorders: rash generalized, skin irritation, erythema. Renal and urinary disorders: dysuria. Ear and Labyrinth Disorders: vertigo. 6.3 Drug Withdrawal/Post-Removal Symptoms Symptoms such as dizziness, nausea, vomiting, abdominal cramps, sweating, headache mental confusion, muscle weakness, bradycardia and hypotension may occur following abrupt discontinuation of anticholinergic drugs such as Transderm Scōp. Similar symptoms, including disturbances of equilibrium, have been reported in some patients following discontinuation of use of the Transderm Scōp system. These symptoms usually do not appear until 24 hours or more after the patch has been removed. These symptoms can be severe and may require medical intervention. Some symptoms may be related to adaptation from a motion environment to a motion-free environment. . Page 5 of 17 Reference ID: 3301616 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda These symptoms can be severe and may require medical intervention. 7 DRUG INTERACTIONS The absorption of oral medications may be decreased during the concurrent use of scopolamine because of decreased gastric motility and delayed gastric emptying. [see Warnings and Precautions (5.3)] Scopolamine should be used with caution in patients taking other drugs that are capable of causing CNS effects such as sedatives, tranquilizers, or alcohol. Special attention should be paid to potential interactions with drugs having anticholinergic properties; e.g., other belladonna alkaloids, antihistamines (including meclizine), tricyclic antidepressants, and muscle relaxants. In vitro studies indicated that the potential for scopolamine to alter the pharmacokinetics of other concomitant medications through inhibition of CYP 1A2, 2C8, 2C9, 2C19, 2D6 and 3A4 or induction of CYP 1A2 and 3A4 is low; however, in vivo studies have not been conducted. [see Clinical Pharmacology (12.3)] 7.1 Laboratory Test Interactions Scopolamine will interfere with the gastric secretion test. 8 USE IN SPECIFIC POPULATIONS 8.1 Pregnancy Pregnancy Category C Based on data from one prospective study of Transderm Scōp in cesarean delivery, the rate of newborn adverse events in both the Transderm Scōp and placebo groups were the same. The rates were 10.5% (12 events in 114 newborns) in both treatment groups. None of these events were considered life threatening or drug related. Jaundice was the only adverse event occurring more frequently with Transderm Scōp than placebo: 9 events (7.9%) versus 2 events (1.8%) (p=0.031). Jaundice, a common occurrence in newborns, resolved with ultraviolet light and did not prolong the hospital stay. There are no adequate and well-controlled studies of Transderm Scōp use during pregnancy. In animal reproduction studies, when pregnant rats and rabbits received scopolamine hydrobromide by daily intravenous injection, no adverse effects were observed in rats. An embryotoxic effect was observed in rabbits at doses producing plasma levels approximately 100 times the levels achieved in humans using a transdermal system. Transderm Scōp should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus and the mother. 8.2 Labor and Delivery During a clinical study among women undergoing cesarean section treated with Transderm Scōp in conjunction with epidural anesthesia and opiate analgesia, no evidence of CNS depression was found in newborns. [see Clinical Studies (14.2)] Scopolamine administered parenterally to rats and rabbits at doses higher than the dose delivered by Transderm Scōp did not affect uterine contractions or increase the duration of labor. Scopolamine does cross the placenta. 8.3 Nursing Mothers Scopolamine is excreted in human milk. Caution should be exercised when Transderm Scōp is administered to a nursing woman. 8.4 Pediatric Use A safe and effective dose has not been established in the pediatric population. [see Warnings and Precautions (5.6)] 8.5 Geriatric Use Transderm Scōp should be used with caution in the elderly because of the increased likelihood of CNS effects, such as hallucinations, confusion and dizziness. Clinical trials of Transderm Scop did not include sufficient number of subjects aged 65 years and older to determine if they respond differently from younger subjects. [see Warnings and Precautions (5.6)] 8.6 Renal or Hepatic Impairment Transderm Scōp should be used with caution in individuals with impaired renal or hepatic functions because of the increased likelihood of CNS effects. [see Warnings and Precautions (5.6)] 9 DRUG ABUSE AND DEPENDENCE 9.1 Controlled Substance Class Scopolamine is not a controlled substance. Page 6 of 17 Reference ID: 3301616 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda 9.2 Abuse Scopolamine is an antagonist at muscarinic receptors in the cholinergic system. Drugs in this class are not known to have significant abuse potential in humans. 9.3 Dependence Abrupt termination of Transderm Scōp may result in withdrawal symptoms such as dizziness, nausea, vomiting, abdominal cramps, sweating, headache, mental confusion, muscle weakness, bradycardia and hypotension. [see Adverse Reactions (6.3) and Overdosage (10)] These withdrawal symptoms indicate that anticholinergic drugs, like scopolamine may produce physical dependence. These symptoms can be severe and may require medical intervention. 10 OVERDOSAGE Because strategies for the management of drug overdose continually evolve, it is strongly recommended that a poison control center be contacted to obtain up-to-date information regarding the management of Transderm Scōp® patch overdose. The prescriber should be mindful that antidotes used routinely in the past may no longer be considered optimal treatment. For example, physostigmine, used more or less routinely in the past, is seldom recommended for the routine management of anticholinergic syndromes. Until up-to-date authoritative advice is obtained, routine supportive measures should be directed to maintaining adequate respiratory and cardiac function. The signs and symptoms of anticholinergic toxicity include: lethargy, somnolence, coma, confusion, agitation, hallucinations, convulsion, visual disturbance, dry flushed skin, dry mouth, decreased bowel sounds, urinary retention, tachycardia, hypertension, and supraventricular arrhythmias. These symptoms can be severe and may require medical intervention. In cases of toxicity remove the patch. Serious symptomatic cases of overdosage involving multiple patch applications and/or ingestion may be managed by initially ensuring the patient has an adequate airway, and supporting respiration and circulation. This should be rapidly followed by removal of all patches from the skin and the mouth. If there is evidence of patch ingestion, gastric lavage, endoscopic removal of swallowed patches, or administration of activated charcoal should be considered, as indicated by the clinical situation. In any case where there is serious overdosage or signs of evolving acute toxicity, continuous monitoring of vital signs and ECG, establishment of intravenous access, and administration of oxygen are all recommended. The symptoms of overdose/toxicity due to scopolamine should be carefully distinguished from the occasionally observed syndrome of withdrawal. [see Adverse Reactions (6.3)] Although mental confusion and dizziness may be observed with both acute toxicity and withdrawal, other characteristic findings differ: tachyarrhythmias, dry skin, and decreased bowel sounds suggest anticholinergic toxicity, while bradycardia, headache, nausea and abdominal cramps, and sweating suggest post-removal withdrawal. Obtaining a careful history is crucial to making the correct diagnosis. 11 DESCRIPTION The Transderm Scōp® (scopolamine) transdermal system is a circular flat patch designed for continuous release of scopolamine following application to an area of intact skin on the head, behind the ear. Each system contains 1.5 mg of scopolamine base. Scopolamine is α -(hydroxymethyl) benzeneacetic acid 9-methyl-3-oxa-9-azatricyclo [3.3.1.02,4] non-7-yl ester. The empirical formula is C17H21NO4 and its structural formula is: structural formula Scopolamine is a viscous liquid that has a molecular weight of 303.35 and a pKa of 7.55-7.81. The Transderm Scōp system is a film 0.2 mm thick and 2.5 cm2, with four layers. Proceeding from the visible surface towards the surface attached to the skin, these layers are: (1) a backing layer of tan-colored, aluminized, polyester film; (2) a drug reservoir of scopolamine, light mineral oil, and polyisobutylene; (3) a microporous polypropylene membrane that controls the rate of delivery of scopolamine from the system to the skin surface; and (4) an adhesive formulation of mineral oil, polyisobutylene, and scopolamine. A protective peel strip of siliconized polyester, which covers the adhesive layer, is removed before the system is used. The inactive components, light mineral oil (12.4 mg) and polyisobutylene (11.4 mg), are not released from the system.

For current labeling information, please visit https://www.fda.gov/drugsatfda Cross section of the system: usage illustration 12 CLINICAL PHARMACOLOGY 12.1 Mechanism of Action Scopolamine, a belladonna alkaloid, is an anticholinergic agent. Scopolamine acts: i) as a competitive inhibitor at postganglionic muscarinic receptor sites of the parasympathetic nervous system, and ii) on smooth muscles that respond to acetylcholine but lack cholinergic innervation. It has been suggested that scopolamine acts in the central nervous system (CNS) by blocking cholinergic transmission from the vestibular nuclei to higher centers in the CNS and from the reticular formation to the vomiting center. Scopolamine can inhibit the secretion of saliva and sweat, decrease gastrointestinal secretions and motility, cause drowsiness, dilate the pupils, increase heart rate, and depress motor function. 12.3 Pharmacokinetics The pharmacokinetics of scopolamine delivered via the system are due to the characteristics of both the drug and dosage form. The system is formulated to deliver in-vivo approximately 1 mg of scopolamine at an approximately constant rate to the systemic circulation over 3 days. Upon application to the postauricular skin, an initial priming dose of scopolamine is released from the adhesive layer to saturate skin-binding sites. The subsequent delivery of scopolamine to the blood is determined by the rate controlling membrane and is designed to produce stable plasma levels in a therapeutic range. Following removal of the used system, there is some degree of continued systemic absorption of scopolamine bound in the skin layers. Absorption Scopolamine is well absorbed percutaneously. Following application to the skin behind the ear, circulating plasma levels are detected within 4 hours with peak levels being obtained, on average, within 24 hours. The average plasma concentration produced is 87 pg/mL (0.28 nM) for free scopolamine and 354 pg/mL for total scopolamine (free + conjugates). Distribution The distribution of scopolamine is not well characterized. It crosses the placenta and the blood brain barrier and may be reversibly bound to plasma proteins. Metabolism and Excretion The exact elimination pattern of scopolamine has not been determined. Following patch removal, plasma levels of scopolamine decline in a log linear fashion with an observed half-life of 9.5 hours. Less than 10% of the total dose is excreted in the urine as the parent drug and metabolites over 108 hours. Scopolamine is extensively metabolized and conjugated with less than 5% of the total dose appearing unchanged in the urine. The enzymes responsible for metabolizing scopolamine are unknown. Drug Interaction An in vitro study using human hepatocytes examined the induction of CYP1A2 and CYP3A4 by scopolamine. Scopolamine did not induce CYP1A2 and CYP3A4 isoenzymes at the concentrations up to 10 nM. In an in vitro study using human liver microsomes which evaluated the inhibition of CYP1A2, 2C8, 2C9, 2C19, 2D6 and 3A4, scopolamine did not inhibit these cytochrome P450 isoenzymes at the concentrations up to 1 mcM. 13 NONCLINICAL PHARMACOLOGY 13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility No long-term studies in animals have been conducted to evaluate the carcinogenic potential of scopolamine. The mutagenic potential of scopolamine has not been evaluated. Fertility studies were performed in female rats and revealed no evidence of impaired fertility or harm to the fetus due to scopolamine hydrobromide administered by daily subcutaneous injection. Maternal body weights were reduced in the highest-dose group (plasma level approximately 500 times the level achieved in humans using a transdermal system). However, fertility studies in male animals were not performed. Page 8 of 17 Reference ID: 3301616 This label may not be the latest approved by FDA. For current labeling information, please visit https://www.fda.gov/drugsatfda 14 CLINICAL STUDIES 14.1 Motion Sickness In 195 adult subjects of different racial origins who participated in clinical efficacy studies at sea or in a controlled motion environment, there was a 75% reduction in the incidence of motion-induced nausea and vomiting. 14.2 Post-Operative Nausea and Vomiting In two pivotal clinical efficacy studies in 391 adult female patients undergoing cesarean section or gynecological surgery with anesthesia and opiate analgesia, 66% of those treated with Transderm Scōp® (compared to only 46% of those receiving placebo) reported no retching/vomiting within the 24-hour period following administration of anesthesia/opiate analgesia. When the need for additional antiemetic medication was assessed during the same period, there was no need for medication in 76% of patients treated with Transderm Scōp as compared to 59% of placebo-treated patients. 16 HOW SUPPLIED/STORAGE AND HANDLING The Transderm Scōp® system is a tan-colored circular patch, 2.5 cm2, on a clear, oversized, hexagonal peel strip, which is removed prior to use. Each Transderm Scōp system contains 1.5 mg of scopolamine and is formulated to deliver in-vivo approximately 1 mg of scopolamine over 3 days. Transderm Scōp is available in packages of four patches. Each patch is foil wrapped. Patient instructions are included. [see Patient Counseling Information (17)]  1 Package (4 patches) NDC 0067-4345-04 Storage The system should be stored at controlled room temperature between 20°C-25°C (68°F-77°F). Handling Since scopolamine can cause temporary dilation of the pupils and blurred vision if it comes in contact with the eyes, patients should be strongly advised to wash their hands thoroughly with soap and water immediately after handling the patch. In addition, it is important that used patches be disposed of properly to avoid contact with children or pets.
