EpiPen is an adrenaline auto-injector (AAI) designed for the emergency treatment of the symptoms of a severe allergic reaction, known as anaphylaxis. Such a reaction can occur when your immune system overreacts to an innocuous substance such as food or medication. It can also happen as a result of insect stings, exercise or exposure to latex.
The symptoms of anaphylactic shock include breathing difficulties, swelling of the tongue, mouth or throat, wheezing, and collapse and unconsciousness. A serious medical emergency, anaphylaxis can develop rapidly and can pose a threat to life. EpiPen administers a dose of epinephrine, also known as adrenaline, to control symptoms and get the sufferer out of harm’s way.
