What it means
An epinephrine auto-injector (brand name EpiPen) is a pre-filled, spring-loaded device used to inject epinephrine (adrenaline) into the outer thigh muscle during a severe allergic reaction (anaphylaxis). Anaphylaxis is a life-threatening emergency that can cause throat swelling, difficulty breathing, and a sudden drop in blood pressure. Epinephrine rapidly reverses these symptoms. After using an auto-injector, call 911 or go to the ER immediately, as symptoms may return. People with known severe allergies are prescribed auto-injectors to carry at all times. In hospitals, epinephrine is administered by staff. Inform healthcare providers of all your allergies.
