what is in an epipen

An EpiPen is an auto-injector that contains epinephrine, a medication that can help decrease the bodys allergic reaction. The EpiPen auto-injector delivers a single dose 0.3 ml injection equal to 0.3 mg adrenaline when activated. The pH range of the solution in the EpiPen Jr Auto-Injector is 2.2-5.0, and it contains 0.15 mg epinephrine, 1.8 mg sodium chloride, 0.5 mg sodium metabisulfite, hydrochloric acid to adjust pH, and Water for Injection. The device is designed to be user-friendly and is available in two formats: EpiPen and EpiPen Jr, which are single-use injectable devices that deliver a fixed dose of epinephrine. The medication in the EpiPen works by relaxing the muscles in the airways to make breathing easier, helping to reverse the rapid and dangerous decrease in blood pressure, and relaxing the muscles in the stomach, intestines, and bladder. EpiPen is indicated in the emergency treatment of allergic reactions (Type I) including anaphylaxis to stinging insects, biting insects, allergen immunotherapy, foods, drugs, diagnostic testing substances, and other allergens, as well as idiopathic anaphylaxis or exercise-induced anaphylaxis.
