Numerous clinical trials have shown topical imiquimod (Aldara) to be effective and safe for the treatment of anogenital warts. In addition, the recurrence rate appears to be lower than those reported for many standard therapies of genital warts. Clinical experience with this medication since its availability 2 years ago has shown that it is important in the therapy of this disease. However, it is not the ideal treatment in all cases, and the advantages and disadvantages in individual patients must be considered.
