RECENT MAJOR CHANGES Dosage and Administration ( 2 ) 11/2017

1 INDICATIONS AND USAGE AUVI-Q® is indicated in the emergency treatment of allergic reactions (Type I) including anaphylaxis to stinging insects (e.g., order Hymenoptera, which include bees, wasps, hornets, yellow jackets and fire ants) and biting insects (e.g., triatoma, mosquitoes), allergen immunotherapy, foods, drugs, diagnostic testing substances (e.g., radiocontrast media) and other allergens, as well as idiopathic anaphylaxis or exercise-induced anaphylaxis. AUVI-Q is intended for immediate administration in patients who are determined to be at increased risk for anaphylaxis, including individuals with a history of anaphylactic reactions. Anaphylactic reactions may occur within minutes after exposure and consist of flushing, apprehension, syncope, tachycardia, thready or unobtainable pulse associated with a fall in blood pressure, convulsions, vomiting, diarrhea and abdominal cramps, involuntary voiding, wheezing, dyspnea due to laryngeal spasm, pruritus, rashes, urticaria or angioedema. AUVI-Q is intended for immediate self-administration as emergency supportive therapy only and is not a substitute for immediate medical care. AUVI-Q contains epinephrine, a non-selective alpha and beta-adrenergic receptor agonist, indicated in the emergency treatment of allergic reactions (Type I) including anaphylaxis. ( 1 )

6 ADVERSE REACTIONS Due to lack of randomized, controlled clinical trials of epinephrine for the treatment of anaphylaxis, the true incidence of adverse reactions associated with the systemic use of epinephrine is difficult to determine. Adverse reactions reported in observational trials, case reports, and studies are listed below. Common adverse reactions to systemically administered epinephrine include anxiety; apprehensiveness; restlessness; tremor; weakness; dizziness; sweating; palpitations; pallor; nausea and vomiting; headache; and/or respiratory difficulties. These symptoms occur in some persons receiving therapeutic doses of epinephrine, but are more likely to occur in patients with hypertension or hyperthyroidism [ see WARNINGS AND PRECAUTIONS ( 5.5 ) ]. Arrhythmias, including fatal ventricular fibrillation, have been reported, particularly in patients with underlying cardiac disease or those receiving certain drugs [ see WARNINGS AND PRECAUTIONS ( 5.5 ) and DRUG INTERACTIONS ( 7 ) ]. Rapid rises in blood pressure have produced cerebral hemorrhage, particularly in elderly patients with cardiovascular disease [ see WARNINGS AND PRECAUTIONS ( 5.5 ) ]. Angina may occur in patients with coronary artery disease [ see WARNINGS AND PRECAUTIONS ( 5.5 ) ]. Rare cases of stress cardiomyopathy have been reported in patients treated with epinephrine. Accidental injection into the digits, hands or feet may result in loss of blood flow to the affected area [ see WARNINGS AND PRECAUTIONS ( 5.2 ) ]. Adverse events experienced as a result of accidental injections may include increased heart rate, local reactions including injection site pallor, coldness and hypoesthesia or injury at the injection site resulting in bruising, bleeding, discoloration, erythema or skeletal injury. Injection of epinephrine into the buttock has resulted in cases of gas gangrene [ see WARNINGS AND PRECAUTIONS ( 5.2 ) ]. Rare cases of serious skin and soft tissue infections, including necrotizing fasciitis and myonecrosis caused by Clostridia (gas gangrene), have been reported at the injection site following epinephrine injection in the thigh [ see WARNINGS AND PRECAUTIONS ( 5.2 ) ]. Adverse reactions to epinephrine include anxiety, apprehensiveness, restlessness, tremor, weakness, dizziness, sweating, palpitations, pallor, nausea and vomiting, headache, and/or respiratory difficulties.

7 DRUG INTERACTIONS Cardiac glycosides, diuretics, or anti-arrhythmics: observe for development of cardiac arrhythmias. ( 7.1 ) Tricyclic antidepressants, monoamine oxidase inhibitors, levothyroxine sodium, certain antihistamines, and catechol-O-methyl transferase inhibitors may potentiate effects of epinephrine. ( 7.2 ) Beta-adrenergic blocking drugs antagonize cardiostimulating and bronchodilating effects of epinephrine. ( 7.3 ) Alpha-adrenergic blocking drugs antagonize vasoconstricting and hypertensive effects of epinephrine. ( 7.3 ) Ergot alkaloids may reverse the pressor effects of epinephrine. ( 7.3 ) 7.1 Drugs Increasing Risk of Cardiac Arrhythmias Observe patients who receive epinephrine while concomitantly taking cardiac glycosides, diuretics, or anti-arrhythmics for the development of cardiac arrhythmias [see Warnings and Precautions ( 5.3 ) and Adverse Reactions ( 6 )] . 7.2 Drugs Potentiating Effects of Epinephrine The effects of epinephrine may be potentiated by tricyclic antidepressants, monoamine oxidase inhibitors, levothyroxine sodium, and certain antihistamines, notably chlorpheniramine, tripelennamine, and diphenhydramine, and catechol-O-methyl transferase (COMT) inhibitors such as entacapone. 7.3 Drugs Antagonizing Effects of Epinephrine The cardiostimulating and bronchodilating effects of epinephrine are antagonized by beta- adrenergic blocking drugs, such as propranolol. The vasoconstricting and hypertensive effects of epinephrine are antagonized by alpha- adrenergic blocking drugs, such as phentolamine. Ergot alkaloids may also reverse the pressor effects of epinephrine.

8 USE IN SPECIFIC POPULATIONS Elderly patients may be at greater risk of developing adverse reactions. ( 8.5 ) 8.1 Pregnancy Risk Summary Prolonged experience with epinephrine use in pregnant women over several decades, based on published literature, have not identified a drug associated risk of major birth defects, miscarriage or adverse maternal or fetal outcomes. There are risks to the mother and fetus associated with anaphylaxis. Epinephrine is first-line treatment of anaphylaxis and should not be delayed (see Clinical Considerations ) . In animal reproductive studies, epinephrine administered by the subcutaneous route to rabbits, mice, and hamsters during the period of organogenesis was teratogenic at doses 7 times and higher than the maximum recommended human intramuscular and subcutaneous dose on a mg/m 2 basis (see Data ) . The background risk of major birth defects and miscarriage for the indicated population is unknown. All pregnancies have a background risk of birth defect, loss, or other adverse outcomes. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2% to 4% and 15% to 20%, respectively. Clinical Considerations Disease-associated maternal and embryo/fetal risk: During pregnancy, anaphylaxis can be catastrophic and can lead to hypoxic-ischemic encephalopathy and permanent central nervous system damage or death in the mother and, more commonly, in the fetus or neonate. Treatment of anaphylaxis during pregnancy should not be delayed. Data Animal Data: In an embryofetal development study with rabbits dosed during the period of organogenesis, epinephrine was shown to be teratogenic (including gastroschisis and embryonic lethality) at doses approximately 40 times the maximum recommended intramuscular or subcutaneous dose (on a mg/m 2 basis at a maternal subcutaneous dose of 1.2 mg/kg/day for two to three days). In an embryofetal development study with mice dosed during the period of organogenesis, epinephrine was shown to be teratogenic (including embryonic lethality) at doses approximately 8 times the maximum recommended intramuscular or subcutaneous dose (on a mg/m 2 basis at a maternal subcutaneous dose of 1 mg/kg/day for 10 days). These effects were not seen in mice at approximately 4 times the maximum recommended daily intramuscular or subcutaneous dose (on a mg/m 2 basis at a subcutaneous maternal dose of 0.5 mg/kg/day for 10 days). In an embryofetal development study with hamsters dosed during the period of organogenesis from gestation days 7 to 10, epinephrine was shown to be teratogenic at doses approximately 7 times the maximum recommended daily intramuscular or subcutaneous dose (on a mg/m 2 basis at a maternal subcutaneous dose of 0.5 mg/kg/day for 4 days). 8.2 Lactation Risk Summary There is no information on the presence of epinephrine in human milk, the effects on breastfed infants, or the effects on milk production. However, due to its poor oral bioavailability and short half-life, transfer of epinephrine into breastmilk is expected to be low. Treatment of anaphylaxis in breastfeeding patients should not be delayed. 8.4 Pediatric Use The safety and effectiveness of AUVI-Q for the emergency treatment of type I allergic reactions, including anaphylaxis have been established in pediatric patients who weigh 7.5 kg or greater. The use of AUVI-Q for this indication is supported by clinical experience. Clinical experience with the use of epinephrine suggests that the adverse reactions seen in pediatric patients are similar in nature and extent to those both expected and reported in adults. Since the doses of epinephrine delivered from AUVI-Q are fixed, use other forms of injectable epinephrine if doses lower than 0.1 mg are deemed necessary. The safety and effectiveness of AUVI-Q have not been established in pediatric patients who weigh less than 7.5 kg. 8.5 Geriatric Use Clinical studies of AUVI-Q for emergency treat …

12.1 Mechanism of Action Epinephrine acts on both alpha and beta-adrenergic receptors. Through its action on alpha-adrenergic receptors, epinephrine lessens the vasodilation and increased vascular permeability that occurs during anaphylaxis, which can lead to loss of intravascular fluid volume and hypotension. Through its action on beta-adrenergic receptors, epinephrine causes bronchial smooth muscle relaxation and helps alleviate bronchospasm, wheezing and dyspnea that may occur during anaphylaxis. Epinephrine also alleviates pruritus, urticaria, and angioedema and may relieve gastrointestinal and genitourinary symptoms associated with anaphylaxis because of its relaxer effects on the smooth muscle of the stomach, intestine, uterus and urinary bladder.

Epinephrine is a sympathomimetic catecholamine. Chemically, epinephrine is (-)-3,4-Dihydroxy-α-[(methylamino)methyl]benzyl alcohol with the following structure: Epinephrine solution deteriorates rapidly on exposure to air or light, turning pink from oxidation to adrenochrome and brown from the formation of melanin. AUVI-Q is not made with natural rubber latex. AUVI-Q instructional and safety systems should be thoroughly reviewed with patients and caregivers prior to use [ see PATIENT COUNSELING INFORMATION ( 17.1 ) ]. Chemical Structure

10 OVERDOSAGE Overdosage of epinephrine has been reported to produce extremely elevated arterial pressure, which may result in cerebrovascular hemorrhage, particularly in elderly patients. Overdosage may also result in pulmonary edema because of peripheral vascular constriction together with cardiac stimulation. Epinephrine overdosage can also cause transient bradycardia followed by tachycardia, which may be accompanied by fatal cardiac arrhythmias; premature ventricular contractions followed by multifocal ventricular tachycardia; atrial tachycardia and occasionally by atrioventricular block; extreme pallor and coldness of the skin; metabolic acidosis; kidney failure. Epinephrine is rapidly inactivated in the body and treatment following overdosage with epinephrine is primarily supportive. Treatment of epinephrine associated pulmonary edema consists of a rapidly acting alpha-adrenergic blocking drug (such as phentolamine mesylate) and respiratory support. Treatment of epinephrine associated arrhythmias consists of administration of a beta-adrenergic blocking drug (such as propranolol). If necessary, pressor effects may be counteracted by rapidly acting vasodilators or α-adrenergic blocking drugs. If prolonged hypotension follows such measures, it may be necessary to administer another pressor drug. Consider contacting the Poison Help line (1-800-222-1222) or a medical toxicologist for additional overdosage management recommendations.
