EpiPen (Adrenaline)

An EpiPen is a device that delivers a precise dose of adrenaline (epinephrine) quickly to the body during a severe allergic reaction, known as anaphylaxis. Adrenaline works by narrowing blood vessels, opening airways, and increasing blood flow, which helps reverse life-threatening symptoms like swelling, difficulty breathing, and low blood pressure. The EpiPen is designed for rapid, easy use by non-medical individuals, providing critical intervention until professional medical help is available. It is life-saving in emergencies, effectively reducing the severity of allergic reactions and preventing potentially fatal outcomes.
