About Sinecatechins (Generic Veregen)

How does it work?

Sinecatechins are natural substances found in green tea leaves. Scientists aren’t exactly sure how this medicine works, but studies show it helps completely clear warts in more than half of people who use it.

What does it treat?

This medicine is used to treat genital warts. Warts are flat, fleshy, skin-colored growths that can appear around the penis, vagina and anus after someone is infected with HPV (human papillomavirus). While it won’t cure the virus that causes warts, this medicine can make warts disappear and help you stay clear for several months after finishing a full course of treatment.

What forms does it come in?

Sinecatechins usually come in the form of a topical ointment that you apply directly on top of warts. It’s only for warts on the penis, vagina or anus – don’t use it in other places on your body or put it inside the vagina or rectum.

Sinecatechins vs. Veregen

Sinecatechins and Veregen are the same thing – Veregen is just a brand name for the medication. Right now, only the brand medicine is available, so it can be more expensive than other genital warts treatments.

How do I use this medication?

This ointment is applied directly onto the warts, three times a day. Avoid getting the medicine on healthy skin, and be sure to wash your hands before and after using this medicine.

Be aware that this medicine can stain bedding or clothes. Don’t cover the warts with a bandage or tight-fitting clothing. This could increase the chances of skin irritation.

What happens if I miss a dose?

If you forget to apply a dose, use it as soon as you remember. Then, continue with your regular schedule. Don't apply extra ointment to make up for the missed dose.

What happens if I use too much?

Using too much of this medicine can cause skin irritation or other side effects. It's important to use only the amount recommended by your licensed provider. Using extra ointment won’t help you get better faster.

If you’ve taken too much Sinecatechins, call your medical provider or local poison control center (800-222-1222) immediately.
