EpiPen is an adrenaline auto-injector (AAI) designed for the emergency treatment of the symptoms of a severe allergic reaction known as anaphylaxis. Although some allergic reactions can be simply uncomfortable or unsightly as a result of mild swelling or a rash, anaphylactic shock can be far more severe. It occurs when your immune system overreacts to an innocuous substance such as food or medication but 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. It can happen anywhere up to an hour or two after coming into contact with an allergen though generally, anaphylaxis will develop very suddenly and rapidly, making it life-threatening. The EpiPen administers a dose of epinephrine, also known as adrenaline, to control symptoms of shock and get the sufferer out of harm’s way.
