What is Diphenhydramine?

Diphenhydramine is an over-the-counter antihistamine that works by blocking histamine receptors in the body.

Histamine is a chemical produced by the immune system in response to allergens, leading to symptoms such as sneezing, itching, watery eyes, and runny nose.

By blocking histamine, diphenhydramine helps alleviate these uncomfortable symptoms.
