Epinephrine (EpiPen)

Epinephrine, often delivered via an EpiPen, is a medication used to treat severe allergic reactions (anaphylaxis). It works quickly to constrict blood vessels, which helps raise blood pressure, and relaxes the muscles in the airways, making it easier to breathe. This response can reverse the life-threatening symptoms of an allergic attack until further medical help is available. Epinephrine is essential for individuals with known severe allergies, providing rapid relief in emergencies. It is typically administered as a shot in the thigh and should be used immediately when a serious allergic reaction occurs.
