Derma-Pax lotion

Generic Name: diphenhydramine (DYE-fen-HYE-dra-meen)
Brand Name: Derma-Pax

Derma-Pax lotion is used for:

Temporarily relieving pain and itching associated with insect bites, minor burns, sunburn, minor skin irritations, minor cuts, scrapes, and rashes due to poison ivy, poison oak, and poison sumac.

Derma-Pax lotion is an antihistamine. It works by blocking the action of histamine, which reduces the symptoms of an allergic reaction.

Contact your doctor or health care provider right away if any of these apply to you.
