How does this medication work? What will it do for me?
Glucagon belongs to the group of medications called hyperglycemic agents. It is used to treat severe hypoglycemia (low blood sugar) when someone with insulin-treated diabetes is unable to give glucose to themselves (e.g., unconscious). Symptoms of severely low blood sugar include disorientation, unconsciousness, and seizures.
This medication works in the liver to produce glucose (sugar) and increase blood sugar. It usually works within 10 to 15 minutes. If a person does not respond to this medication within 10 to 15 minutes, get immediate medical attention.
Glucagon can also be used as part of certain radiologic tests to temporarily reduce the movement of the stomach and intestines.
This medication may be available under multiple brand names and/or in several different forms.

Your doctor may have suggested this medication for conditions other than those listed in these drug information articles. If you have not discussed this with your doctor or are not sure why you are being given this medication, speak to your doctor.

What form(s) does this medication come in?
Each 1 mg/mL vial is supplied as a sterile, freeze-dried white powder of glucagon in a 2 mL vial and accompanying solvent also in a 2 mL vial. Glucagon powder is reconstituted with 1.0 mL of water for injection (WFI), forming a solution of 1 mg (1 IU) glucagon and 107 mg of lactose monohydrate in each mL prior to use. One stoppered glass vial contains 1 mg glucagon, corresponding to 1 mg glucagon/mL after reconstitution. Nonmedicinal ingredients: lactose monohydrate, hydrochloric acid and/or sodium hydroxide (pH adjusters), and water for injection.
Each 1 mg/mL vial is supplied as a sterile, freeze-dried white powder of glucagon in a 2 mL vial and accompanying solvent in a 1.5 mL disposable syringe. Glucagon powder is reconstituted with 1.0 mL of water for injection (WFI), forming a solution of 1 mg (1 IU) glucagon and 107 mg of lactose monohydrate in each mL prior to use. Nonmedicinal ingredients: lactose monohydrate, hydrochloric acid and/or sodium hydroxide (pH adjusters), and water for injection.
How should I use this medication?
The usual dose for adults and children who weigh more than 25 kg (55 lbs) and are 6 to 8 years and older is 1 mg (1 unit) injected into a muscle. For children who weigh less than 25 kg (55 lbs) and are younger than 6 to 8 years, the dose is 0.5 mg (0.5 units) or based on body weight.
To give a glucagon injection, first prepare the injection. Do not prepare the injection until the medication is needed. Once prepared, use it immediately and do not store for later use.
- Remove the plastic cap from the vial.
- Pull the needle cap cover off the syringe.
- Draw up the water for injection (1.1 mL) in a disposable syringe (not needed for Hypokit).
- Insert the needle through the rubber stopper (within the marked circle) and inject the water for injection into the vial containing the freeze-dried glucagon.
- Without taking the needle out of the vial, shake the vial gently until the glucagon is completely dissolved and the solution is clear.
- Make sure the plunger is completely down. While keeping the needle in the liquid, slowly withdraw the solution back into the syringe.
- Remove any air bubbles from the syringe by tapping on the needle with the needle pointing upwards, and push the plunger slightly to release any air that has collected at the top of the syringe.
- Continue to push the plunger until you have the correct dose.
- Inject into a muscle.
As soon as someone responds to this medication, they should eat glucose (e.g., candy, orange juice, regular pop) to prevent low blood sugar from returning and contact their doctor.

Are there any other precautions or warnings for this medication?
Before you begin using a medication, be sure to inform your doctor of any medical conditions or allergies you may have, any medications you are taking, whether you are pregnant or breast-feeding, and any other significant facts about your health. These factors may affect how you should use this medication.
Alcohol: Alcohol ingestion (acute or chronic) can reduce the effectiveness of this medication.
Insulinoma/glucagonoma: If you have an insulinoma (a tumour of the pancreas that produces insulin) or a glucagonoma (tumour of the pancreas that produces glucagon), discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.
Knowledge of use: This medication is usually given by family members, friends, or coworkers, as it should not be used unless the individual needing the medication cannot take glucose by mouth. Make sure that these people are familiar with when and how to use this medication and where you store it.
Pheochromocytoma: This is a tumour of the adrenal gland that affects how and when the body produces chemicals that increase heart rate and blood pressure. For people with pheochromocytoma, glucagon can cause the tumour to release larger than normal amounts of these chemicals, causing a rapid, possibly dangerous, climb in blood pressure. If you have a history of pheochromocytoma, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication and whether any special monitoring is needed.
Pregnancy: This medication should not be used during pregnancy unless the benefits outweigh the risks, and only if sugar cannot be given.
Breast-feeding: It is not known if glucagon passes into breast milk. If you are a breast-feeding mother and are taking this medication, it may affect your baby. Talk to your doctor about whether you should continue breast-feeding.
