An EpiPen is a brand of epinephrine auto-injector, a medical device used to treat severe allergic reactions (anaphylaxis). Anaphylaxis can occur quickly and can be life-threatening if not treated promptly. Common triggers include foods (such as nuts, shellfish, and dairy), insect stings, medications, and latex.

Key Points:

• EpiPens deliver a measured dose of epinephrine to help reduce the body’s allergic reaction.
• Epinephrine works by relaxing the muscles in the airways and tightening the blood vessels.

Carrying an EpiPen is crucial for individuals with a history of severe allergies.
