Question

Quizplus · Accepted Answer

Histamine is the primary physiologically active amine responsible for the signs and symptoms encountered in an allergic reaction, such as itching, redness, swelling, and increased mucus production. Epinephrine is sometimes used as a treatment for severe allergic reactions, but it is not the amine responsible for the symptoms. Diphenhydramine and phenylephrine are medications used to treat symptoms of allergies, but they are not the actual amine produced during an allergic reaction. Dopamine is not typically associated with allergic reactions.
