Caprex (Generic)

This medication is used to treat minor aches and pains of the muscles/joints (e.g., arthritis, backache, sprains). Capsaicin works by decreasing a certain natural substance in your body (substance P) that helps pass pain signals to the brain.

Use this medication on the skin only. Follow all directions on the product package. If you have any questions, ask your doctor or pharmacist.

For the cream, gel, and lotion forms, apply a thin layer of medication to the affected area and rub in gently and thoroughly. You may want to use a cotton ball/swab or latex glove to apply the medication to avoid touching the medication with your hands.

Do not apply the medication in the eyes, mouth, nostrils, or genitals. If you do get the medication in those areas, flush with plenty of water. Also, do not apply this medication to skin that is injured or irritated (for example, cut, scraped, sunburned).

Do not apply this medication immediately before or after activities such as bathing, swimming, sun bathing, or heavy exercise. Do not bandage or wrap the affected area or use a heating pad on that area. Doing so may increase the risk of side effects.

After applying the medication, wash your hands unless you are using this medication to treat the hands. If treating the hands, wait at least 30 minutes after applying the medication to wash your hands.

Coughing, sneezing, watery eyes, or throat irritation may occur if you breathe in the dried residue from the medication. Use caution to avoid inhaling the residue.

If your doctor has directed you to use this medication, remember that he or she 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.
