The EpiPen® auto-injector is a disposable drug delivery system featuring spring activation and a concealed needle. It is designed for self-administration of epinephrine in acute allergic emergencies (anaphylaxis). It provides a rapid, convenient dose of epinephrine for individuals needing protection from potentially fatal allergic reactions.

Epinephrine by injection is the treatment of choice for anaphylactic reactions because it quickly begins working to reverse symptoms of an anaphylactic reaction. Epinephrine constricts blood vessels, relaxes smooth muscles in the lungs to improve breathing, stimulates the heartbeat, and works to reverse hives and swelling around the face and lips. The effects of epinephrine usually last 10 to 20 minutes.

Epinephrine dosing is based on body weight. Your doctor will prescribe what is right for you. The EpiPen® auto-injector delivers 0.3 mg intramuscular dose of epinephrine from injection 1:1000 USP. Intended for individuals weighing 66 lbs. or more.
