This medication is used on the skin to stop itching and
pain from certain skin conditions (such as scrapes, minor burns, eczema,
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). Some forms of this
medication are also used to decrease discomfort or pain during certain
medical procedures/exams (such as sigmoidoscopy, cystoscopy). Lidocaine is
a local anesthetic that works by causing temporary numbness/loss of feeling
in the skin and mucous membranes.
If you are using the over-the-counter product to
self-treat, read and follow 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 on the skin, clean and dry the affected area
as directed. Apply a thin layer of medication to the affected area of skin,
usually 2 to 3 times a day or as directed.
If you are using the spray, shake the canister well
before using. While holding the canister 3-5 inches (8-13 centimeters) from
the affected area, spray until wet. If the affected area is on the face,
spray the medication onto your hand and apply to the face. Do not spray
near your eyes, nose, or mouth.
If you are using the foam, shake the canister well
before using. Spray the foam onto your hand and apply to the affected
area.
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. These may increase the risk of serious side
effects.
Wash hands immediately after use unless you are treating
an area on the hands. Avoid getting the product in eyes, nose, or ears. If
the medication gets in these areas, rinse the area immediately with clean
water.
The dosage is based on your medical condition and
response to treatment. Do not use more of this product, use it more often,
or keep using it longer than directed. If there is an infection or sore in
the area to be treated, do not use this medication without consulting your
doctor first.
If your condition lasts or gets worse, or if you think
you may have a serious medical problem, get medical help right
away.
Temporary redness, stinging, and a little bit of
swelling may occur at the application site. If these effects last or get
worse, tell your doctor right away.
