The Role of Epinephrine
Epinephrine, the first-line treatment of life-threatening allergic reactions (anaphylaxis) according to NIH-NIAID Food Allergy guidelines, is the drug product found in the EpiPen® and EpiPen Jr® Auto-Injectors (0.3 and 0.15 mg epinephrine). During a life-threatening allergic reaction (anaphylaxis), epinephrine quickly begins working to reverse symptoms of a life-threatening allergic reaction (anaphylaxis) by constricting blood vessels to increase blood pressure, relaxing smooth muscles in the lungs to reduce wheezing to improve breathing, stimulating the heart (increasing heart rate), and working to reduce hives as well as swelling that may occur around the face and lips.
Be sure to tell your doctor all the medicines you take, especially medicines for asthma. Side effects may be increased in patients with certain medical conditions, or who take certain medicines. These include asthma, allergies, depression, thyroid disease, Parkinson's disease, diabetes, high blood pressure and heart disease.
