Glucagon can be given by injection to restore blood glucose lowered by insulin even in unconscious patients. It can increase glucose release from glycogen stores more than insulin can suppress it.

Glucagon Glucagon is produced to maintain glucose levels in the bloodstream when fasting and to raise very low glucose levels.
What is glucagon? To do this, it acts on the liver in several ways: It stimulates the conversion of stored glycogen stored in the liver to glucose, which can be released into the bloodstream. This process is called glycogenolysis. It promotes the production of glucose from amino acid molecules. This process is called gluconeogenesis. It reduces glucose consumption by the liver so that as much glucose as possible can be secreted into the bloodstream to maintain blood glucose levels.
