How does this medication work? What will it do for me?
Diphenhydramine belongs to a group of medications known as antihistamines. Antihistamines are used to treat symptoms caused by allergies, including itchy and watery eyes, sneezing, runny nose, and skin rash and irritations.
The cream form of this medication is used for the relief of swelling and itching caused by insect bites, poison ivy, poison oak, mild cases of sunburn, and other minor skin irritations.
This medication works by blocking the effects of histamine, a substance released by the body involved in allergies. It usually starts to work within one hour.
