What is Glucagon for?

Glucagon is a natural hormone found in our body. Glucagon raises blood sugar levels, whereas the hormone insulin lowers blood sugar levels. Both hormones work together to keep blood sugar levels stable and provide the body with the energy it requires. Glucagon can be injected into our bodies to treat severe hypoglycaemia (low blood sugar levels) emergencies.

How to use it?

Glucagon is injected under the skin or into a muscle or a vein as directed by your doctor in case of very low blood sugar levels.


You may need to administer Glucagon at home, either to yourself or to a family member.


The usual administration dose is 1 mg for adults and children over 25 kg, or 0.5 mg for children under 25 kg. When the patient responds to Glucagon, give oral carbohydrates (sugar) immediately. If the patient does not respond within 10 minutes, glucose will be administered directly into the vein via a needle. Glucagon administration may be repeated if necessary.


GlucaGen Hypokit Bydureon® comes as a dry powder. Mix the dry powder with the syringe of sterile water that comes with the kit. Do not use any other liquid to mix the medicine. Inject all contents in the syringe (1 ml) into the skin. For children who need 0.5 ml, slowly push the plunger down until it is at the 0.5 ml mark on the syringe.
