Diphenhydramine Topical (patient information)

# Why this medication is prescribed
Diphenhydramine, an antihistamine, is used to relieve the itching of insect bites, sunburns, bee stings, poison ivy, poison oak, and minor skin irritation.
This medication is sometimes prescribed for other uses; ask your doctor or pharmacist for more information.

# How this medication should be used
Diphenhydramine topical comes in cream, lotion, gel, and spray to be applied to the skin. It is used three or four times a day. Follow the directions on the package or on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Use diphenhydramine exactly as directed. Do not use more or less of it or use it more often than directed by your doctor.
Thoroughly clean the infected area, allow it to dry, and then gently rub the medication in until most of it disappears. Use just enough medication to cover the affected area. You should wash your hands after applying the medication.
Do not apply diphenhydramine on chicken pox or measles, and do not use it on a child younger than 2 years of age unless directed to do so by a doctor.

# Special precautions
Before using diphenhydramine:
- tell your doctor and pharmacist if you are allergic to diphenhydramine or any other drugs.
- tell your doctor and pharmacist what prescription and nonprescription medications you are taking, including vitamins.
- tell your doctor if you are pregnant, plan to become pregnant, or are breast-feeding. If you become pregnant while using diphenhydramine, call your doctor.
- plan to avoid unnecessary or prolonged exposure to sunlight and to wear protective clothing, sunglasses, and sunscreen. Diphenhydramine may make your skin sensitive to sunlight.

# What to do if you forget a dose
Apply the missed dose as soon as you remember it. However, if it is almost time for the next dose, skip the missed dose and continue your regular dosing schedule. Do not apply a double dose to make up for a missed one.

# Side effects
Diphenhydramine may cause side effects. Tell your doctor if any of these symptoms are severe or do not go away:
- skin rash
- sunburn
- increased sensitivity to sunlamps and sunlight
