1 INDICATIONS AND USAGE Glucagon for Injection is an antihypoglycemic agent and a gastrointestinal motility inhibitor indicated: for the treatment of severe hypoglycemia in pediatric and adult patients with diabetes ( 1.1 ) as a diagnostic aid for use during radiologic examinations to temporarily inhibit movement of the gastrointestinal tract in adult patients ( 1.2 ) 1.1 Severe Hypoglycemia Glucagon for Injection is indicated for the treatment of severe hypoglycemia in pediatric and adult patients with diabetes. 1.2 Diagnostic Aid Glucagon for Injection is indicated as a diagnostic aid for use during radiologic examinations to temporarily inhibit movement of the gastrointestinal tract in adult patients.

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, the 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.

7 DRUG INTERACTIONS Beta-blockers : Patients taking beta-blockers may have a transient increase in pulse and blood pressure. ( 7.1 ) Indomethacin: In patients taking indomethacin Glucagon for Injection may lose its ability to raise glucose or may produce hypoglycemia. (7.2) Anticholinergic drugs: Concomitant use of anticholinergic drugs with Glucagon for Injection for use as a diagnostic aid is not recommended. (7.3) Warfarin: Glucagon for Injection may increase the anticoagulant effect of warfarin. (7.4) Insulin: Monitor blood glucose when Glucagon for Injection is used as a diagnostic aid in patients receiving insulin. (7.5) 7.1 Table 3: Clinically Significant Drug Interactions with Glucagon for Injection Beta-Blockers Clinical Impact: Patients taking beta-blockers may have a transient increase in pulse and blood pressure when given Glucagon for Injection. Intervention: The increase in blood pressure and heart rate may require therapy in patients with coronary artery disease. Indomethacin Clinical Impact: In patients taking indomethacin, Glucagon for Injection 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 Clinical Impact: The concomitant use of anticholinergic drugs and Glucagon for Injection increases the risk of gastrointestinal adverse reactions due to additive effects on inhibition of gastrointestinal motility. Intervention: Concomitant use of anticholinergic drugs with Glucagon for Injection for use as a diagnostic aid is not recommended. Warfarin Clinical Impact: Glucagon for Injection may increase the anticoagulant effect of warfarin. Intervention: Monitor patients for unusual bruising or bleeding, as adjustments in warfarin dosage may be required. Insulin Clinical Impact: Insulin acts antagonistically to glucagon. Intervention: Monitor blood glucose when Glucagon for Injection is used as a diagnostic aid in patients receiving insulin.

12 CLINICAL PHARMACOLOGY 12.1 Mechanism of Action Glucagon increases blood glucose concentration by activating hepatic glucagon receptors, thereby stimulating glycogen breakdown and release of glucose from the liver. Hepatic stores of glycogen are necessary for glucagon to produce an antihypoglycemic effect. Extrahepatic effects of glucagon include relaxation of the smooth muscle of the stomach, duodenum, small bowel, and colon. 12.2 Pharmacodynamics Treatment of Severe Hypoglycemia Blood glucose concentration rises within 10 minutes of injection and maximal concentrations are attained at approximately 30 minutes after injection (see Figure 1). The duration of hyperglycemic action after intravenous or intramuscular injection is 60 to 90 minutes. Figure 1.

13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility Carcinogenesis Long term studies in animals to evaluate carcinogenic potential have not been performed. Mutagenesis Synthetic glucagon was negative in the bacterial reverse mutation assay (Ames test). The clastogenic potential of synthetic glucagon in the Chinese Hamster Ovary (CHO) assay was positive in the absence of metabolic activation. Doses of 100 and 200 mg/kg of glucagon of both pancreatic and recombinant origins gave slightly higher incidences of micronucleus formation in male mice but there was no effect in females. The weight of evidence indicates that synthetic and recombinant glucagon are not different and do not pose a genotoxic risk to humans. Impairment of Fertility Glucagon was not tested in animal fertility studies. Studies in rats have shown that pancreatic glucagon does not cause impaired fertility.

Instructions for Use Glucagon (GLOO-ka-gon) for injection, for subcutaneous, intramuscular or intravenous use Read this Instructions for Use before you start using Glucagon and each time you get a refill. There may be new information. This information does not take the place of talking with your doctor about your medical condition or treatment. Talk to your doctor or pharmacist if you have any questions about how to use Glucagon. Important: Read and become familiar with this Instructions for Use before an emergency happens . Show your family members and others where you keep your Glucagon Emergency Kit for Low Blood Sugar and how to use it the right way. Call for emergency medical help right after you use Glucagon. Do not share your Glucagon syringes or needles with another person. You may give other people a serious infection or other people may get a serious infection from you. The prefilled syringe that comes with your Glucagon Emergency Kit for Low Blood Sugar is meant for use with Glucagon only. Do not use Glucagon syringes to inject other medicines. How should I store Glucagon? Before you mix the Glucagon powder and liquid: Store Glucagon at room temperature between 68° to 77°F (20° to 25°C). Check the expiration date on your vial of Glucagon. Do not use Glucagon if the expiration date has passed. Do not freeze Glucagon. Keep Glucagon in its original package and Glucagon out of light. After you mix the Glucagon powder and liquid: Use Glucagon right away. Throw away any unused Glucagon. Glucagon should be clear and colorless. Do not use Glucagon if it is cloudy or if you see particles in the solution. Supplies you will need for your Glucagon injection (See Figure A ): 1 Glucagon Emergency Kit for Low Blood Sugar that contains: 1 vial that contains 1 mg of Glucagon for injection and 1 prefilled glass syringe with attached needle that contains 1 mL of Sterile Water for Injection. Figure A 1 puncture resistant container for throwing away used needles and syringes. See “How should I dispose of (throw away) used Glucagon prefilled syringes” at the end of these instructions. Cotton ball or gauze pad (not included in kit) Preparing the Glucagon dose: The Glucagon medicine comes as a dry powder. Before you use Glucagon, you must mix the dry powder with the syringe of sterile water that comes in the Glucagon Emergency Kit for Low Blood Sugar. Do not use any other liquid to mix the medicine. Check that the orange plastic cap on your vial of Glucagon is firmly attached. Do not use the vial of Glucagon if the orange plastic cap is loose or missing. Step 1 . Using your thumb, flip the orange plastic cap off the Glucagon vial ( See Figure B ). Figure B Step 2 . Pick up the prefilled syringe containing sterile water. Hold the syringe with 1 hand and with your other hand pull the needle cover off the syringe ( See Figure C ). Do not remove the plastic backstop from the syringe. Figure C Step 3. Pick up the Glucagon vial. Hold the vial of dry powder with 1 hand and with your other hand push the needle of the prefilled syringe through the center of the rubber stopper ( See Figure D ). Figure D Step 4 . Hold the vial and syringe together, with the needle still inserted into the vial. Carefully turn the vial and syringe together right side up. Slowly push the plunger down until the syringe is empty ( See Figure E ). Do not take the syringe out of the vial. Figure E Step 5 . Hold the entire unit (the vial and syringe) in 1 hand and gently shake the vial until the powder is completely dissolved ( See Figure F ). Do not use if it is cloudy or if you see particles in the solution. Do not take the syringe out of the vial. Figure F Step 6 . Firmly hold the vial and syringe together, with the needle still inserted into the vial. Carefully turn the vial and syringe together upside down. Gently pull down on the plunger and slowly withdraw all of the liquid into the syringe ( See Figure G ). Do not pull the plunger out of the syringe. Figure G Step 7. Keep the needle inside the vial. Check the syringe for air bubbles. If you see bubbles, tap the syringe until the bubbles rise to the top of the syringe ( See Figure H ). Gently push on the plunger to move only the air bubbles back into the vial. Figure H Step 8 . Hold the vial and syringe as shown ( See Figure I ) Figure I Giving the Glucagon for Injection: Step 9. Choose the injection site ( See Figure J ). Common injection sites for Glucagon are upper arms, thighs, or buttocks. Patient does not need to be laying down to administer the medication as long as the common injection sites can be easily accessed. Figure J Step 10 . With 1 hand gently pinch the skin at the injection site. With your other hand insert the needle into the skin and push the syringe plunger down until the syringe is empty ( See Figure K ). Figure K After Giving the Glucagon injection: Step 11 . Pull the needle out of the skin and press on the injection site ( See Figure L ). Use a gauze pad or cotton ball (not included in the kit) if needed to press the injection site to make sure there is no direct contact with the skin. Figure L Throw away your used syringe with the needle attached and any Glucagon you did not use. See “ How should I dispose of (throw away) used Glucagon prefilled syringes ” at the end of these instructions. Step 12. Turn the person on their side. When an unconscious person awakens, they may vomit. Turning the person on their side will lessen the chance of choking. Step 13. Call for emergency medical help right away. If the person does not respond after 15 minutes, another dose may be given, if available. Step 14. Feed the person as soon as they are awake and able to swallow . Give the person a fast acting source of sugar (such as a regular soft drink or fruit juice) and a long acting source of sugar (such as crackers and cheese or a meat sandwich). Step 15. Even if the Glucagon for Injection treatment wakes the person, tell their doctor right away. The doctor should be told whenever a severe drop in blood sugar (hypoglycemia reaction) happens. The person's dose of diabetes medicine may need to be changed. Hypoglycemia may happen again after receiving Glucagon for Injection treatment. Early symptoms of hypoglycemia may include: sweating drowsiness dizziness sleep disturbances irregular heartbeat (palpitation) anxiety tremor blurred vision hunger slurred speech restlessness depressed mood tingling in the hands, feet, lips, or tongue irritability abnormal behavior lightheadedness unsteady movement inability to concentrate personality changes headache If not treated early, hypoglycemia may worsen and the person may have severe hypoglycemia. Signs of severe hypoglycemia include: confusion unconsciousness seizures death How should I dispose of (throw away) Glucagon pre-filled syringes? Put used syringes in a FDA-cleared sharps disposal container right away after use. Do not throw away (dispose of) loose needles and syringes in your household trash. If you do not have a FDA-cleared sharps disposal container, you may use a household container that is: made of a heavy-duty plastic, can be closed with a tight-fitting, puncture-resistant lid, without sharps being able to come out, upright and stable during use, leak-resistant, and properly labeled to warn of hazardous waste inside the container. When your sharps disposal container is almost full, you will need to follow your community guidelines for the right way to dispose of your sharps disposal container. There may be state or local laws about how you should throw away used needles and syringes. For more information about safe sharps disposal, and for specific information about sharps disposal in the state that you live in, go to the FDA's website at: http://www.fda.gov/safesharpsdisposal.

8.4 Pediatric Use The safety and effectiveness of Glucagon for Injection for the treatment of severe hypoglycemia in pediatric patients with diabetes have been established. Safety and effectiveness for use as a diagnostic aid during radiologic examinations to temporarily inhibit movement of the gastrointestinal tract in pediatric patients have not been established.

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 rat and rabbit reproduction studies, no embryofetal toxicity was observed with glucagon administered by injection during the period of organogenesis at doses representing up to 100 and 200 times the human dose, respectively, 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 rats and rabbits given glucagon by injection at doses of 0.4, 2.0, and 10 mg/kg (up to 100 and 200 times the human dose based on mg/m 2 for rats and rabbits, respectively) there was no evidence of increased malformations or embryofetal lethality.
