Epinephrine Definition

Epinephrine is an injection-based medication used to treat life-threatening allergic reactions called anaphylaxis (an-a-fi-LAK-sis). These very serious reactions are most commonly caused by foods, drugs and stinging insects.

People with severe allergy or a history of anaphylaxis should carry an epinephrine autoinjector with them at all times. 

Epinephrine typically comes as a single-dose pre-filled automatic injection device to be injected into the thigh.

After you use the epinephrine autoinjector, go the closest emergency room immediately. Later, check back with your allergist / immunologist.
