If you decide to treat your flat warts, your doctor may prescribe a topical cream. These creams are irritants and cause the skin to peel, which removes the warts. Prescriptive creams may include:
retinoic acid 0.05 percent cream, known as tretinoin (AVITA, Refissa, Retin-A, Tretin-X)
Imiquimod 5 percent cream (Aldara, Zyclara)
Topical 5-fluorouracil (Carac, Efudex, Fluoroplex, Tolak), 1 percent or 5 percent cream
Your doctor may also suggest 5 percent benzoyl-peroxide (Del Aqua, NeoBenz Micro, Clearskin, EFFACLAR), which is available over the counter.
