Uses

Sinecatechins are used to treat warts on and around the genitals and anus. These warts are caused by the human papillomavirus (HPV). Sinecatechins are natural substances found in certain green tea leaves. It is not known how this medication works.

This medication does not cure warts, but it may help the infection clear faster. New warts may occur during or after treatment. This medication does not prevent the spread of warts through sexual contact, and it may weaken condoms and diaphragms. Talk to your doctor about safer sex practices.

How to Use This Medication

Read the Patient Information Leaflet if available from your pharmacist before you start using this product and each time you get a refill. If you have any questions, ask your doctor or pharmacist.

Use this medication on the skin only. Wash your hands before and after applying. Apply the ointment to all warts as directed by your doctor, usually 3 times a day. Use your finger to apply a small amount, about 0.2 inches (0.5 centimeters), to completely cover each wart with a thin layer. Do not wash off the ointment from the previous treatment before re-applying. Always re-apply the ointment after taking your usual baths/showers. Do not cover the treated area with bandages or other waterproof dressings. You may cover the area with cotton gauze or cotton underwear. Do not use more often or for longer than prescribed.

Male patients who are not circumcised and who are treating warts under the foreskin should pull the foreskin back and clean the area daily, then apply this medication.

Women using tampons should insert the tampon before applying the ointment. If you need to change the tampon while the ointment is on the skin, avoid getting the ointment inside the vagina.

Do not use this medication inside the vagina or anus or on an open sore. Avoid touching your eyes, nose, or mouth while the ointment is on your finger. If you get this medication in those areas, flush with plenty of water. If irritation occurs, contact your doctor right away.

Avoid sexual contact while using this product. This product may weaken condoms and vaginal diaphragms. This effect increases the risk of pregnancy and passing sexually transmitted disease (including genital warts) to others. Wash the product off before sexual activity. Ask your doctor about safer sex practices.

Use this medication regularly to get the most benefit from it. Continue treatment until the warts are gone. Do not use for longer than 16 weeks unless directed by your doctor. Tell your doctor if your condition does not improve or if new warts appear.
