Uses

This product is used on the skin for the short-term relief of pain and itching from certain skin conditions (such as sunburn, scrapes, minor cuts/burns/skin irritation, insect bites). Benzocaine is a local anesthetic that works by causing temporary numbness/loss of feeling in the skin. Menthol works by causing the skin to feel cool and then warm to distract you from feeling the pain and itching.

How to use

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, clean and dry the affected area as directed. Apply a thin layer of medication to the affected area of skin as directed, not more than 3 to 4 times a day.

Hold the can 6 to 12 inches (15 to 30 centimeters) from the affected area and spray on the skin. Do not spray on your face or in your mouth. If you need to apply this medication to your face, spray it into the palm of your hand and gently apply it to your face.

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 age, medical condition, and response to treatment. Do not use more of this product, use it more often, or use it longer than directed. Your condition will not improve any faster, and your risk of side effects will increase.

If your condition lasts for more than 7 days, gets worse, gets better and then comes back again in a few days, or if you think you may have a serious medical problem, get medical help right away.

Side effects

Temporary redness, stinging, or irritation at the application site may occur. If any of these effects last or get worse, tell your doctor or pharmacist promptly.

If your doctor has directed you to use this medication, remember that your doctor has judged that the benefit to you is greater than the risk of side effects. Many people using this medication do not have serious side effects.

Get medical help right away if you have any very serious side effects, including:

This effect is more likely if you have breathing problems, certain diseases of the blood, or if you smoke (see also Precautions section).

Stop using this medication and get medical help right away if you develop any symptoms of methemoglobinemia, including:

  • pale/bluish/gray skin

  • shortness of breath
  • fast heartbeat
