Imiquimod 5% cream (Aldara, Graceway Pharmaceuticals) is an immune response modifier used for the topical treatment of anogenital warts in non-HIV-infected patients. Several randomized controlled trials have demonstrated that imiquimod 5% cream is a safe and efficacious treatment. Current data regarding efficacy shows that complete clearance of warts occurred in up to 50% of patients treated with imiquimod 5% cream applied once-daily, 3 times per week for up to 16 weeks. Recurrence rates ranged from up to 19% at 3 months to 23% at 6 months. Imiquimod 5% cream showed an acceptable safety profile; local inflammatory reactions were the most frequent adverse effects, with local erythema being the most common.
