Generic Name: glucagon (GLOO-ka-gon)
Brand Name: GlucaGen
Glucagon is used for:
Treating severe low blood sugar in patients with diabetes who are unable to take sugar by mouth. Glucagon also may be used for other conditions as determined by your doctor.
Glucagon is a hormone. It works by stimulating the liver to release glucose into the blood.
Do NOT use glucagon if:
- you are allergic to any ingredient in glucagon, including lactose
- you have certain tumors on your adrenal gland (pheochromocytoma) or pancreas (insulinoma)
Contact your doctor or health care provider right away if any of these apply to you.
Before using glucagon:
Some medical conditions may interact with glucagon. Tell your doctor or pharmacist if you have any medical conditions, especially if any of the following apply to you:
- if you are pregnant, planning to become pregnant, or are breast-feeding
- if you are taking any prescription or nonprescription medicine, herbal preparation, or dietary supplement
- if you have allergies to medicines, foods, or other substances
- if you have adrenal gland problems, heart problems, chronic low blood sugar, a certain tumor on your pancreas (glucagonoma), or diabetes
- if you are malnourished or have been unable to eat, or if you have been fasting for a long period of time
Some MEDICINES MAY INTERACT with glucagon. Tell your health care provider if you are taking any other medicines, especially any of the following:
- Anticoagulants (eg, warfarin) because the risk of their side effects, including increased risk of bleeding, may be increased by glucagon
- Beta-blockers (eg, propranolol) or indomethacin because they may decrease glucagon's effectiveness
- Anticholinergics (eg, tolterodine) because the risk of stomach or bowel side effects may be increased
This may not be a complete list of all interactions that may occur. Ask your health care provider if glucagon may interact with other medicines that you take. Check with your health care provider before you start, stop, or change the dose of any medicine.

Important safety information:
- Always carry a quick source of sugar such as candy or glucose tablets to take at the first warning sign of a low blood sugar reaction.
