Adrenaline is used in the treatment of severe allergic reactions, glaucoma, decreased blood pressure, local anesthesia, bleeding, allergic conditions and cardiac arrest.

Adrenaline is an alpha- and beta-adrenergic agonist. It relaxes muscles in your lungs and relieves spasm, wheezing, and shortness of breath that occurs during a severe allergic reaction (anaphylaxis).

Most side effects do not require any medical attention and disappear as your body adjusts to the medicine. Consult your doctor if they persist or if you’re worried about them
