The EpiPen® auto-injector is a disposable drug delivery system featuring a concealed needle and spring activation. It is designed for self-administration of epinephrine in acute allergic emergencies (anaphylaxis). It provides a rapid, convenient dose of epinephrine for individuals who need to treat potentially fatal allergic reactions.
Epinephrine by injection is the treatment of choice for anaphylactic reactions since 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.
