Glucagon, like insulin, must be injected. Within the glucagon kit are a syringe pre-filled with a liquid and a vial of powdered glucagon. You prepare the glucagon for injection immediately before use by following the instructions that are included with the glucagon kit. This method can lessen the rebound hyperglycemia that usually ensues after use of glucagon. There is no danger of overdose, however.
Injection is given in a large muscle, such as the buttocks, thigh or arm.
Glucagon can cause vomiting, so be sure to place the person on his or her side prior to injecting so they do not choke. After injecting glucagon, follow with food once the person regains consciousness and is able to swallow. In the United States, the glucagon kit is dispensed by presecription only.
