Glucagon for Injection is for subcutaneous, intramuscular, or intravenous injection. Administer intravenously ONLY under medical supervision.
Instruct patients and their caregivers on the signs and symptoms of severe hypoglycemia. Because severe hypoglycemia requires the help of others to recover, instruct the patient to inform those around them about Glucagon for Injection and its Instructions for Use. Administer Glucagon for Injection as soon as possible when severe hypoglycemia is recognized.
Instruct the patient or caregiver to read the Instructions for Use at the time they receive a prescription for Glucagon for Injection. Emphasize the following instructions to the patient or caregiver:
Adults and Pediatric Patients Weighing 20 kg or More
Pediatric Patients Weighing Less Than 20 kg
Glucagon for Injection is a white to off white lyophilized powder supplied as follows:
Glucagon for Injection is contraindicated in patients with:
Glucagon for Injection is contraindicated in patients with pheochromocytoma because glucagon may stimulate the release of catecholamines from the tumor [see Contraindications (4)]. If the patient develops a substantial increase in blood pressure and a previously undiagnosed pheochromocytoma is suspected, 5 to 10 mg of phentolamine mesylate, administered intravenously, has been shown to be effective in lowering blood pressure.
In patients with insulinoma, administration of glucagon may produce an initial increase in blood glucose; however, Glucagon for Injection administration may directly or indirectly (through an initial rise in blood glucose) stimulate exaggerated insulin release from an insulinoma and cause hypoglycemia. Glucagon for Injection is contraindicated in patients with insulinoma [see Contraindications (4)]. If a patient develops symptoms of hypoglycemia after a dose of Glucagon for Injection, give glucose orally or intravenously.
Allergic reactions have been reported with glucagon, these include generalized rash, and in some cases anaphylactic shock with breathing difficulties and hypotension. Glucagon for Injection is contraindicated in patients with a prior hypersensitivity reaction [see Contraindications (4)].
Glucagon for Injection is effective in treating hypoglycemia only if sufficient hepatic glycogen is present. Patients in states of starvation, with adrenal insufficiency or chronic hypoglycemia may not have adequate levels of hepatic glycogen for Glucagon for Injection administration to be effective. Patients with these conditions should be treated with glucose.
Necrolytic Migratory Erythema (NME), a skin rash commonly associated with glucagonomas (glucagon-producing tumors) and characterized by scaly, pruritic erythematous plaques, bullae, and erosions, has been reported post marketing following continuous glucagon infusion. NME lesions may affect the face, groin, perineum and legs or be more widespread. In the reported cases, NME resolved with discontinuation of the glucagon, and treatment with corticosteroids was not effective. Should NME occur, consider whether the benefits of continuous glucagon infusion outweigh the risks.
Treatment with Glucagon for Injection in patients with diabetes mellitus may cause hyperglycemia. Monitor diabetic patients for changes in blood glucose levels during treatment and treat if indicated.
Glucagon for Injection may increase myocardial oxygen demand, blood pressure, and pulse rate which may be life-threatening in patients with cardiac disease. Cardiac monitoring is recommended in patients with cardiac disease during use of Glucagon for Injection as a diagnostic aid, and an increase in blood pressure and pulse rate may require therapy.
Glucagon administered to patients with glucagonoma may cause secondary hypoglycemia. Test patients suspected of having glucagonoma for blood levels of glucagon prior to use as a diagnostic aid as Glucagon for Injection is contraindicated in this setting [see Contraindications (4)].
The following important adverse reactions are described below and elsewhere in the labeling:
The following adverse reactions have been identified during post-approval use of glucagon. Because these reactions are reported voluntarily from a population of uncertain size, it is generally not possible to reliably estimate their frequency or establish a causal relationship to drug exposure.
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 increase 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. |
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/m2) (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.
Risk Summary
There is no information available on the presence of glucagon in human or animal milk, the effects of glucagon on the breastfed child or the effects of glucagon 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.
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.
Clinical studies of glucagon 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 when used as a diagnostic aid 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.
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.
Glucagon is an antihypoglycemic agent and a gastrointestinal motility inhibitor. Glucagon is synthesized in a laboratory strain of Escherichia coli bacteria that has been genetically altered by the addition of the gene for glucagon. The chemical structure of the glucagon is identical to human glucagon. Glucagon is a single-chain polypeptide that contains 29 amino acid residues and has a molecular weight of 3483 Daltons.
The empirical formula is C153H225N43O49S. The primary sequence of glucagon is shown below.
Crystalline glucagon is a white to off-white powder. It is relatively insoluble in water but is soluble at a pH of less than 3 or more than 9.5.
Glucagon for Injection is a sterile lyophilized white to off white powder in a vial and a syringe of sterile diluent for intravenous, intramuscular, or subcutaneous use. The vial contains 1 mg of glucagon, 49 mg of lactose monohydrate. Hydrochloric acid may have been added during manufacture to adjust the pH of the glucagon to 2.5 to 3.0. One International Unit of glucagon is equivalent to 1 mg of glucagon. The 1-mL diluent syringe contains 12 mg of glycerin, 1 mg hydrochloric acid, and Water for Injection, at pH 1.8 to 2.2.
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.
Treatment of Severe Hypoglycemia
Blood glucose concentrations rise within 10 minutes of subcutaneous injection and mean maximal concentration of 136 mg/dL is attained 30 minutes after injection (see Figure 1). Similarly, following intramuscular injection, the mean peak glucose level was 138 mg/dL, which occurred at 26 minutes after injection.

Diagnostic Aid
Table 2 displays the dose and pharmacodynamics properties of Glucagon for Injection as a diagnostic aid during radiological examination.
* Administration of 2 mg doses produces a higher incidence of nausea and vomiting than do lower doses. |
|||
Dose | Route of administration | Time of onset of action | Approximate duration of effect |
0.25 – 0.5 mg | Intravenous | 1 minute | 9 – 17 minutes |
1 mg | Intramuscular | 8 – 10 minutes | 12 – 27 minutes |
2 mg* | Intravenous | 1 minute | 22 – 25 minutes |
2 mg* | Intramuscular | 4 – 7 minutes | 21 – 32 minutes |
Absorption
Glucagon injected through the intramuscular route achieved mean peak plasma levels of 6.9 ng/mL at approximately 13 minutes after dosing; and 7.9 ng/mL at approximately 20 minutes after subcutaneous dosing. Administration of the intravenous glucagon showed dose proportionality of the pharmacokinetics between 0.25 and 2 mg.

Long term studies in animals to evaluate carcinogenic potential have not been performed. Recombinant glucagon was positive in the bacterial Ames assay. It was determined that an increase in colony counts was related to technical difficulties in running this assay with peptides. Studies in rats have shown that glucagon does not cause impaired fertility.
Glucagon Emergency Kit for Low Blood Sugar contains 1 mg Glucagon for Injection (a lyophilized white to off-white powder) in a single-dose vial and 1 prefilled syringe containing 1 mL of diluent of Glucagon.

Supplies you will need for your Glucagon for Injection
Preparing to Inject Glucagon for Injection
Step 1: Remove the flip-off seal from the vial of Glucagon. Wipe the rubber stopper on the vial with an alcohol swab (see Figure B).
Step 2: Remove the needle protector from the syringe. Inject all of the diluent in the prefilled syringe into the vial containing Glucagon powder (see Figure C). Do not remove the plastic clip from the syringe. Remove syringe from the vial.
Step 3: Swirl the vial gently until the Glucagon powder dissolves completely (see Figure D). Glucagon should not be used unless the solution is clear and of a water-like consistency.
Step 4: Using the same syringe, hold the vial upside down and, making sure the needle tip remains in the solution, gently withdraw all the solution (1 mg mark on syringe) from the vial (see Figure E). The backstop and plastic clip on the syringe will prevent the rubber stopper from being pulled out of the syringe; however, if the plunger rod separates from the rubber stopper, simply reinsert the rod by turning it clockwise. The usual adult dose is 1 mg. For children weighing less than 44 lb (20 kg), give 1/2 adult dose (0.5 mg). For these children, withdraw 1/2 of the solution from the vial (0.5 mg mark on syringe).
Injecting Glucagon for Injection
Step 5: Choose your injection site and clean with an alcohol wipe. Injection sites for Glucagon for Injection are the buttocks, upper arm, or thigh.
Step 6: Insert the needle into the loose tissue under the clean injection site and push the plunger to inject all (or 1/2 for children weighing less than 44 lbs.) of the Glucagon for Injection.
After injecting Glucagon for Injection
Step 7: Apply light pressure at the injection site and withdraw the needle. Press an alcohol swab against the injection site.
Throw away your used syringe with the needle attached and any Glucagon that you did not use in an FDA-cleared sharps disposal container right away after use. See “How should I dispose of (throw away) used Glucagon syringes?” at the end of these instructions.
Step 8: Turn the person on their side. When an unconscious person wakes up, they may vomit. Turning the person on their side will prevent them from choking.
Step 9: Call for emergency medical help right away.
Step 10: Feed the person as soon as they wake up and are 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 11: If the person does not awaken within 15 minutes, give another dose of Glucagon and inform a doctor or emergency services right away.
Step 12: Even if the Glucagon revives the person, their doctor should be notified right away. A doctor should be notified whenever severe hypoglycemia occurs.
Hypoglycemia may happen again after receiving Glucagon for Injection.
Early symptoms of hypoglycemia (low blood glucose) include:
|
|
If not treated early, the symptoms may progress to severe hypoglycemia. Signs include:
|
|
How should I dispose of (throw away) used Glucagon syringes?
Keep Glucagon for Injection and all medicines out of the reach of children.
