The usual dose of Glucagon for adults and children who weight more than 20 kg (44 lbs) is 1 mg (1 unit) injected under the skin, into a muscle or into a vein. For children who weight less than 20 kg (44 lbs), the dose is 0.5 mg (0.5 unit) or is based on body weight.

Injections into a vein are given by health care professionals with the appropriate training and supplies to do so.

To give a glucagon injection under the skin, first prepare the injection. Once prepared, use it immediately and do not store for later use.

1. Remove the flip-off seal from the vial (bottle) of glucagon.
2. Remove the needle protector from the syringe, and inject the entire contents of the syringe into the bottle of glucagon. Do not remove the plastic clip from the syringe. Remove the syringe from the bottle.
3. Swirl the bottle gently until the glucagon dissolves completely. Glucagon should not be used unless the solution is clear and completely dissolved.
4. Using the same syringe, hold bottle upside down and, making sure the needle tip remains in solution, withdraw all of the solution (1 mg mark on syringe) from the bottle. The plastic clip on the syringe will prevent the plunger from being pulled out of the syringe; however, if the plastic plunger rod separates from the rubber stopper, simply reinsert the rod by turning it clockwise.
5. Clean the injection site on the buttock, arm, or thigh with an alcohol swab.
6. Insert the needle into the fatty tissue under the cleaned injection site, and inject the glucagon solution. There is no danger of overdose.
7. Apply light pressure at the injection site, and withdraw the needle. Press an alcohol swab against the injection site.
8. Turn the patient on their side. When an unconscious person awakens, they may vomit. Turning the patient on their side will prevent them from choking.

As soon as someone responds to Glucagon, they should eat glucose (e.g., candy, orange juice, regular pop) to prevent low blood sugar from returning and contact their doctor.
