This medication is used to temporarily relieve itching
and pain caused by minor burns/cuts/scrapes, sunburn, insect bites, minor
skin irritations, or rashes from poison ivy, poison oak, or poison
sumac.
Diphenhydramine belongs to a class of drugs known as
antihistamines. It works by blocking the effects of a certain natural
substance (histamine) that causes itching. This product may also contain
other ingredients (skin protectants such as allantoin, zinc acetate) that
may help relieve symptoms such as dry skin, weeping, or oozing. Read the
product package for more information.
Depending on the brand and the form of diphenhydramine
skin product you are using, the package information may state that its use
is not recommended in children younger than 2, 6, or 12 years unless
directed by the doctor.
If you are self-treating with this medication, it is
important to read the package instructions carefully before you start using
this product to be sure it is right for you. (See also Precautions
section.)
Use this medication only on the skin as directed by your
doctor. If you are self-treating, follow all directions on the product
package. If you have any questions, ask your doctor or pharmacist. Some
products may need to be shaken well before use.
Before applying, clean the affected area with soap and
water. Gently pat dry. Apply to the affected area as directed, usually no
more than 3 to 4 times a day. Wash hands immediately after use, unless the
area being treated includes the hands.
Do not use on large areas of the body or use more often
than directed. Your condition will not improve any faster, and your risk of
side effects will increase.
Avoid getting the product in your eyes, nose, ears, or
mouth. If the medication gets in these areas, wipe it off and rinse the
area right away with water.
Stop using this product and tell your doctor if your
condition gets worse, if symptoms do not get better within 7 days or last
after 7 days of treatment, or if symptoms clear up and return in a few
days. If you think you may have a serious medical problem, get medical help
right away.
Mild stinging may occur. If this effect lasts or gets
worse, stop using this product and tell your doctor or pharmacist
promptly.
