This medication is used on the skin to stop itching and
pain from certain skin conditions (such as scrapes, minor burns, insect
bites) and to treat minor discomfort and itching caused by hemorrhoids and
certain other problems of the genital/anal area (such as anal fissures,
itching around the vagina/rectum). Benzocaine is a local anesthetic that
works by causing temporary numbness/loss of feeling in the
skin.
If you are using the over-the-counter product to
self-treat, read all directions on the product package before using this
medication. If you have any questions, consult your pharmacist. If your
doctor has prescribed this medication, use it as directed.
Before use, clean and dry the affected area as directed.
Apply a thin layer of medication to the affected area of skin as
directed.
If you are using the spray, shake the can well before
using. Hold the can 6 to 12 inches (15 to 30 centimeters) from the affected
area and spray until wet. Do not spray near your eyes, nose, or
mouth.
Do not use on large areas of the body, cover the area
with waterproof bandages or plastic, or apply heat unless directed to do so
by your doctor. Doing so may increase the risk of serious side
effects.
Wash your hands right after use unless you are treating
an area on the hands. Avoid getting the product in your eyes, nose, or
mouth. If the medication gets in these areas, rinse right away with plenty
of water.
The dosage is based on your medical condition and
response to treatment. Do not use more of this product, use it more often,

application site may occur. If any of these effects last or get worse, tell
your doctor or pharmacist promptly.
