7 DRUG INTERACTIONS Table 4: Clinically Significant Drug Interaction with GVOKE and GVOKE VialDx Beta-Blockers Clincial Impact: Patients taking beta-blockers may have a transient increase in pulse and blood pressure when given GVOKE or GVOKE VialDx. Intervention The increase in blood pressure and heart rate may require therapy in patients with coronary artery disease. Insulin Clincial Impact: Insulin acts antagonistically to glucagon. Intervention Monitor blood glucose when GVOKE VialDx is used as a diagnostic aid in patients receiving insulin. Indomethacin Clincial Impact: In patients taking indomethacin, GVOKE may lose its ability to raise blood glucose or may even produce hypoglycemia. Intervention Monitor blood glucose levels during glucagon treatment of patients taking indomethacin. Anticholinergic Drugs Clincial Impact: The concomitant use of anticholinergic drugs and GVOKE VialDx increases the risk of gastrointestinal adverse reactions due to additive effects on inhibition of gastrointestinal motility. Intervention Concomitant use of anticholinergic drugs with GVOKE VialDx is not recommended. Warfarin Clincial Impact: GVOKE and GVOKE Vial Dx may increase the anticoagulant effect of warfarin. Intervention Monitor patients for unusual bruising or bleeding, as adjustments in warfarin dosage may be required. Beta-blockers: GVOKE- or GVOKE VialDx-treated patients taking concomitant beta-blockers may have a transient increase in pulse and blood pressure. ( 7 ) Indomethacin: In patients taking concomitant indomethacin, GVOKE may lose its ability to raise glucose or may produce hypoglycemia. ( 7 ) Anticholinergic drugs: Concomitant use of anticholinergic drugs with GVOKE VialDx for use as a diagnostic aid is not recommended. ( 7 ) Warfarin: GVOKE and GVOKE VialDx may increase the anticoagulant effect of warfarin. ( 7 ) Insulin: Monitor blood glucose when GVOKE VialDx is used as a diagnostic aid in patients receiving insulin. ( 7 ) See 17 for PATIENT COUNSELING INFORMATION and FDA ‐ approved patient labeling for GVOKE.

8 USE IN SPECIFIC POPULATIONS 8.1 Pregnancy Risk Summary Available data from case reports and a small number of observational studies with glucagon use in pregnant women over decades of use have not identified a drug-associated risk of major birth defects, miscarriage or adverse maternal or fetal outcomes. Multiple small studies have demonstrated a lack of transfer of pancreatic glucagon across the human placental barrier during early gestation. In a rat reproduction study, no embryofetal toxicity was observed with glucagon administered by injection during the period of organogenesis at doses representing up to 40 times the human dose, based on body surface area (mg/m 2 ) (see Data) . The estimated background risk of major birth defects and miscarriage for the indicated population is unknown. 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 In pregnant rats given animal sourced glucagon twice-daily by injection at doses up to 2 mg/kg (up to 40 times the human dose based on body surface area extrapolation, mg/m 2 ) during the period of organogenesis, there was no evidence of increased malformations or embryofetal lethality. 8.2 Lactation Risk Summary There is no information available on the presence of glucagon in human or animal milk, the effects of the drug on the breastfed infant, or the effects of the drug on milk production. However, glucagon is a peptide and would be expected to be broken down to its constituent amino acids in the infant's digestive tract and is therefore, unlikely to cause harm to an exposed infant. 8.4 Pediatric Use The safety and effectiveness of GVOKE for subcutaneous use for the treatment of severe hypoglycemia in patients with diabetes have been established in pediatric patients aged 2 years and older. Use of GVOKE for this indication is supported by evidence from two adequate and well-controlled studies in adults with type-1 diabetes mellitus [see Clinical Studies ( 14.1 )] and from a study in 31 pediatric patients ages 2 and older with type 1 diabetes mellitus [see Clinical Studies ( 14.2 )] . The safety and effectiveness of GVOKE for subcutaneous use for the treatment of severe hypoglycemia in patients with diabetes have not been established in pediatric patients younger than 2 years of age. Safety and effectiveness of GVOKE VialDx for intravenous use as a diagnostic aid during radiologic examinations to temporarily inhibit movement of the gastrointestinal tract in pediatric patients have not been established. 8.5 Geriatric Use Clinical studies of GVOKE and GVOKE VialDx did not include sufficient numbers of patients aged 65 and over to determine whether they respond differently from younger adult patients.

11 DESCRIPTION Glucagon is an antihypoglycemic agent and a gastrointestinal motility inhibitor. Glucagon is a single chain containing 29 amino acid residues and has a molecular weight of 3483 and is identical to human glucagon. Glucagon is of synthetic origin produced by solid phase synthesis.

10 OVERDOSAGE If overdosage occurs, the patient may experience nausea, vomiting, inhibition of GI tract motility, increase in blood pressure, and pulse rate. In case of suspected overdosing, serum potassium may decrease and should be monitored and corrected if needed. If the patient develops a dramatic increase in blood pressure, phentolamine mesylate has been shown to be effective in lowering blood pressure for the short time that control would be needed. In the event of an overdose of GVOKE, consider contacting the Poison Help line (1-800-222-1222) or a medical toxicologist for additional overdosage management recommendation.
