Glucagon is a prescription medication used to treat insulin coma or insulin reaction from very low blood sugar (severe hypoglycemia) in adults and children with diabetes. Glucagon is a hormone, which helps raise sugar levels in the blood.
This medication comes in an injectable form and is injected in the buttock, arm, or thigh during severe hypoglycemic attacks.
Common side effects of glucagon include nausea, vomiting, and reaction at the injection site.
