Description
Benadryl Allergy Relief Capsules are an over-the-counter medication commonly used to alleviate symptoms associated with allergies, such as hay fever, allergic rhinitis, and hives. The active ingredient in Benadryl Allergy Relief Capsules is diphenhydramine hydrochloride, which is an antihistamine.
Antihistamines like diphenhydramine work by blocking the effects of histamine, a substance produced by the body during allergic reactions. Histamine is responsible for causing symptoms such as itching, sneezing, runny nose, and watery eyes. By blocking histamine, Benadryl helps relieve these symptoms.
