Imiquimod in the treatment of recalcitrant warts: a new therapy option?

Recalcitrants viral warts can pose a therapeutic challenge to the treating physician. In a clinical study, we documented the effect of imiquimod 5% cream (Aldara) on recalcitrants warts in 22 patients. A complete and partial clearing of the warts was achieved in 41% and 50%, respectively. In only 9% of patients no improvement could be observed. Beside the very often observed perilesional erythema, which correlated well with good treatment response, no relevant side effects were documented. Imiquimod 5% cream (Aldara) is an efficient, easy to perform ambulatory treatment modality for recalcitrants HPV induced warts with few side effects.
