Veregen (sinecatechins) Ointment is an herbal product made from green tea leaves used to treat external (on the outside of the body) genital and anal warts in adult patients. Veregen will not cure genital or anal warts, and will not prevent spreading the warts to other people through sexual intercourse or skin-to-skin contact. Veregen will not treat genital warts caused by the human papilloma virus (HPV). Common side effects of Veregen Ointment include mild skin reactions of the treated area such as itching, burning, pain, swelling, and redness.

Apply a 0.5 cm dose strand of the Veregen to each wart using the finger(s), dabbing it on to ensure complete coverage and leaving a thin layer of the ointment on the warts. Wash hands before and after application of Veregen. Veregen may interact with other genital wart treatments you have used or are still using. Tell your doctor all medications and supplements you use. During pregnancy, Veregen should be used only when prescribed. It is unknown if Veregen passes into breast milk. Consult your doctor before breastfeeding.

SIDE EFFECTS

Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice.

In Phase 3 clinical trials, a total of 397 subjects received Veregen® three times per day topical application for the treatment of external genital and perianal warts for up to 16 weeks.

Serious local adverse events of pain and inflammation were reported in two subjects (0.5%), both women.

In clinical trials, the incidence of patients with local adverse events leading to discontinuation or dose interruption (reduction) was 5% (19/397). These included the following events: application site reactions (local pain, erythema, vesicles, skin erosion/ulceration), phimosis, inguinal lymphadenitis, urethral meatal stenosis, dysuria, genital herpes simplex, vulvitis, hypersensitivity, pruritus, pyodermitis, skin ulcer, erosions in the urethral meatus, and superinfection of warts and ulcers.

Local and regional reactions (including adenopathy) occurring at >1% in the treated groups are presented in Table 1.
