epipen symptoms
EpiPen is an injection containing epinephrine, a chemical that narrows blood vessels and opens airways in the lungs. These effects can reverse severe low blood pressure, wheezing, severe skin itching, hives, and other symptoms of an allergic reaction. EpiPen is used to treat severe allergic reactions (anaphylaxis) to insect stings or bites, foods, drugs, and other allergens. Epinephrine is also used to treat exercise-induced anaphylaxis. Epinephrine auto-injectors such as EpiPen and EpiPen Jr. may be kept on hand for self-injection by a person with a history of an severe allergic reaction. EpiPen is for use in adults and children who weigh at least 16.5 pounds (7.5 kilograms).
