What is an EpiPen?
An EpiPen is a medical device that injects epinephrine into the body to treat life-threatening allergic reactions.
EpiPens are pre-filled automatic injection devices supplied with small vials containing liquid epinephrine. The liquid solution in the EpiPen is injected subcutaneously (under the skin) or intramuscularly (into a muscle) at the first sign of a serious allergic reaction.
Epinephrine is also used to treat low blood pressure in adults (hypotension) and low blood pressure associated with septic shock (a life-threatening bodywide infection that can cause organ failure and dangerously low blood pressure). As a treatment for low blood pressure, epinephrine is administered intravenously by a health care professional in a hospital.
