Drug Information:
Glucagon is a hormone that increases blood sugar levels. It also slows involuntary muscle movements of the stomach and intestines that aid in digestion. Glucagon nasal (for use in the nose) is used to treat severe hypoglycemia (low blood sugar) in adult and children at least 4 years old. Glucagon may also be used for purposes not listed in this medication guide. Glucagon should be used to treat hypoglycemia only if the person cannot eat, passes out, or is having a seizure. Be sure you know how to give glucagon nasal before you need to use it. Hypoglycemia should be treated as quickly as possible. Having low blood sugar for too long can cause seizure, coma, or death.
