Epi-pen

Epi-pen

Is a medical device for injecting a measured dose or doses of epinephrine by means of auto injector technology. It is most often used for the treatment of anaphylaxis. Epinephrine is effective, by narrowing the blood vessels and opening airways in the lungs. These effects can reverse severe low blood pressure, wheezing, severe skin itching, hives, and other symptoms of an allergic reaction.
