EpiPen (Auto-Injector)

An EpiPen is a medical device that automatically delivers a dose of epinephrine (adrenaline) via injection, typically into the thigh. It is used in emergencies to treat severe allergic reactions (anaphylaxis), which can cause swelling, difficulty breathing, or loss of consciousness. The device is designed for quick, easy use by non-medical personnel, providing rapid relief by constricting blood vessels, relaxing airways, and improving blood pressure. EpiPens are portable, pre-filled, and activated by pressing firmly against the thigh, making them an essential tool for individuals with known severe allergies to respond promptly and effectively during an attack.
