Glucagon is available (by prescription in the US and UK) as a Glucagon Emergency Kit. The kit is held on hand by insulin dependent diabetics and people with hypoglycemic tendencies. The glucagon is in a powered form, and a syringe with saline is included. The saline is injected into the vial of powder to reconstitute the solution, then the solution is drawn back up and injected subq, IM, or IV. 1 mg is the standard dose, though 0.5 mg is effective for many people.
