Glucagon comes in different forms for emergency use, primarily to treat severe hypoglycemia (low blood sugar).
Here's a breakdown:
-
Prefilled Syringe with Solution: Glucagon is available as a ready-to-inject liquid solution in a prefilled syringe. This is administered subcutaneously (under the skin).
-
Auto-Injector: Similar to an EpiPen, glucagon also comes in an auto-injector device, prefilled with the liquid solution. This is also injected subcutaneously. These are convenient for caregivers or individuals who might be hesitant about using a syringe.
-
Powder for Reconstitution: Glucagon also comes as a lyophilized (freeze-dried) powder in a vial. This requires mixing with a supplied liquid diluent before injection. Once mixed, it can be administered:
- Subcutaneously (under the skin)
- Intramuscularly (into the muscle)
- Intravenously (into a vein) - This route is typically used in a hospital setting.
In summary, glucagon comes in ready-to-inject forms (prefilled syringe and auto-injector) and a powder form requiring reconstitution prior to subcutaneous, intramuscular, or intravenous administration.
