Oral cimetidine for the management of genital and perigenital warts in children.

Abstract

It is believed that most warts are self-limiting and generally require little or no treatment. When numerous or almost complete infestation of the perineum, genital area and groin is encountered it can be distressing and a difficult problem to treat in children. Multiple treatments with caustic agents are sometimes necessary, and treatment of perigenital warts may require use of anesthesia for multiple procedures. Cimetidine is a histamine receptor antagonist that has been used mainly to treat peptic ulcer disease. Recently it has been reported to be useful for the treatment of mucocutaneous candidiasis, herpes simplex, herpes zoster and verruca because of its immunomodulatory effects. Several studies have been published indicating its effectiveness in the treatment of warts. We treated 4 children with extensive condylomata acuminata of the genital and perigenital areas with high doses of cimetidine in an attempt to eradicate the condyloma and avoid recurrence in 2 and as primary treatment in 2. All patients were treated with 30 to 40 mg./kg. cimetidine daily in 3 divided doses during a 3-month period. All patients are free of condyloma at 24 months following treatment. Our results show that cimetidine is useful for primary and adjunctive treatment of condyloma in young children. It also appears to be effective as first line therapy.
