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.
This medicine comes with a Patient Information Leaflet. Read it carefully. Ask your doctor, nurse, or pharmacist any questions that you may have about this medicine.
Use this medication on the skin only. Wash your hands before and after applying. Apply the ointment to all warts as prescribed, usually 3 times a day or as directed by your doctor. 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.
Mild skin reactions such as itching/burning/pain/swelling/reddening of the treated area frequently occur. If any of these effects persist or worsen, wash off the ointment with soap and water, stop using this product, and call your doctor promptly.
Remember that your doctor has prescribed this medication because 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.
Tell your doctor right away if any of these unlikely but serious side effects occur: blistering/oozing/peeling skin in treated area, open sore in treated area (skin ulcer).
If you are an uncircumcised male who is using this drug to treat warts on the penis, narrowing of the foreskin (phimosis) may rarely occur. If you notice tightening/pain in your foreskin, tell your doctor right away.
A very serious allergic reaction to this drug is rare. However, seek immediate medical attention if you notice any symptoms of a serious allergic reaction, including: rash, itching/swelling (especially of the face/tongue/throat), severe dizziness, trouble breathing.

Before using this product, tell your doctor or pharmacist if you are allergic to it; or if you are allergic to green tea; or if you have any other allergies. This product may contain inactive ingredients, which can cause allergic reactions or other problems. Talk to your pharmacist for more details.

Genital/anal warts are caused by a virus called human papillomavirus (HPV). This product does not destroy the virus but only helps to get rid of the wart. Therefore, new warts may form even while you are being treated.
You may also be able to infect any sexual partner who comes into contact with the areas of skin infected with HPV. To reduce the risk of spreading HPV to others, always use effective barrier protections (e.g., latex or polyurethane condoms, dental dams) during all sexual activity. Consult your doctor or pharmacist for more details.
During treatment of genital/anal warts, avoid all sexual contact while the ointment is on the skin. Condoms, dental dams, and diaphragms may be weakened by the ointment. Therefore, they may not work as well to prevent pregnancy or the spread of HPV or other sexually transmitted diseases (e.g., HIV).
During pregnancy, this medication should be used only when clearly needed. Discuss the risks and benefits with your doctor.
It is not known whether this drug passes into breast milk. Consult your doctor before breast-feeding.
Your doctor or pharmacist may already be aware of any possible drug interactions and may be monitoring you for them. Do not start, stop, or change the dosage of any medicine before checking with your doctor or pharmacist first.
Before using this medication, tell your doctor or pharmacist of all prescription and nonprescription/herbal products you may use, especially of: drugs that may affect the immune system (e.g., chemotherapy, cyclosporine, corticosteroids such as hydrocortisone/prednisone).
Keep a list of all your medications with you, and share the list with your doctor and pharmacist.
