For adults with severely low blood sugar, the standard dosage of glucagon is 1 mg (1 unit). Younger and/or lighter children typically receive half the normal adult dosage. Glucagon is usually given just under the skin of a buttock, arm, or thigh. If the person does not wake up within 15 minutes of their injection, give another dose and seek immediate medical attention.
An Introduction to Dosing With GlucagonThe dose of glucagon your healthcare provider recommends will vary, depending on factors such as your:
- Weight (for children).
As is always the case, do not adjust your dosage unless your healthcare provider specifically tells you to do so.
The best treatment for severely low blood sugar (hypoglycemia) is an intravenous sugar solution, such as glucose or dextrose. If such treatment is not immediately available, glucagon should be given. For adults, the standard dose is 1 mg (1 unit) given just under the skin (subcutaneously), into a muscle (intramuscularly), or into a vein (intravenously).
Depending on your child's age and weight, as well as the particular glucagon product used, the amount could either be the full adult dose (for older and/or heavier children) or half the normal adult dose (for younger and/or lighter children). The half-dose is 0.5 mg (0.5 unit) given just under the skin, into a muscle, or into a vein.
When in doubt, do not worry about giving too much glucagon. The risks from an overdose are minimal, compared to the risks from untreated low blood sugar. If the person does not wake up within 15 minutes, a second dosage should be given and emergency medical attention should be sought. No matter what the outcome, you should always contact a healthcare provider any time glucagon is used.
