• Podophyllin 10-25%
Accessible meatal warts may be treated with podophyllin, 10-25%, in compound tincture of benzoin, or podophyllotoxin 0.5% where available. Great care should be taken to ensure that the treated area is dried before contact with normal, opposing epithelial surfaces is allowed. Low success rates with podophyllin are reported.
Urethroscopy is necessary to diagnose intra-urethral warts, but they should be suspected in men with recurrent meatal warts. Some experts prefer electrosurgical removal. Intra-urethral instillation of a 5% cream of fluorouracil or thiotepa may be effective, but neither has been adequately evaluated. Podophyllin should not be used.
