Administration of epinephrine is the first-line treatment for anaphylaxis, which is a severe, life-threatening allergic reaction. Epinephrine works quickly to improve breathing, stimulate the heart, raise a dropping blood pressure, reverse hives, and reduce swelling of the face, lips, and throat. Oxygen supplementation, corticosteroids, and antihistamines are also used in the management of anaphylaxis but are secondary to the immediate administration of epinephrine.
