This medication is used on the skin to stop itching and pain from certain skin conditions (e.g., 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 (e.g., 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 (e.g., sigmoidoscopy, cystoscopy). Lidocaine is a local anesthetic that works by causing temporary numbness/loss of feeling in the skin and mucous membranes.
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.
