What is Sinecatechins (Veregen)?
Sinecatechins is a prescription medicine made from green tea extracts. It is sold under the brand name Veregen and is used to treat external genital warts (condyloma acuminata) in adults when the warts are visible on the skin and not inside the vagina, urethra, or anus. [1]
How does Veregen work?
Veregen is an immunomodulating, anti-inflammatory topical therapy. The active green-tea polyphenols are thought to help the immune system respond to human papillomavirus (HPV) that causes genital warts, which can reduce wart size and number over time. [1]
How is Veregen applied?
Veregen is a topical ointment. Patients typically apply it directly to the affected wart areas as directed by their clinician, usually avoiding use on irritated or broken skin and following the specific treatment schedule on the prescription instructions. [1]
How long is treatment usually?
Treatment duration depends on how the warts respond. The product’s prescribed course is designed to continue until the warts are cleared or until a maximum treatment period is reached, as guided by the prescriber. [1]
What side effects do patients report?
Common side effects are usually local and skin-related where the ointment is applied, such as redness, itching, burning, pain, and irritation. People with significant local reactions should talk with their clinician about whether to adjust or stop treatment. [1]
Is Veregen the only option for genital warts?
No. Genital warts can also be treated with other patient-applied topical medicines and clinician-administered procedures. The best choice depends on wart size and location, prior treatment history, and tolerability. [1]
