Description
Indications
Diphenhydramine is commonly used to alleviate itching and discomfort resulting from minor burns, cuts, scrapes, sunburn, insect bites, and skin irritations. Diphenhydramine can also be effective in reducing itching associated with allergic reactions, such as those caused by exposure to poison ivy, poison oak, or poison sumac.
Diphenhydramine is classified as an antihistamine, it works by blocking the effects of histamine, a natural substance in the body that plays a role in allergic reactions. By inhibiting histamine, diphenhydramine helps relieve symptoms such as itching and pain caused by various skin conditions and irritations.
