Mechanism of action against these HPV-induced lesions is unknown. 5% cream is applied 3 times weekly and washed off 6-10 hours after each application. Recurrences appear to be less common than with ablative therapies. Local skin reactions and pigmentary skin lesions are the important side effects.
Resiquimod is another immunomodulator, which is used topically for HSV.
Podophyllin acts by inhibiting the polymerization of tubulin monomers in the mitotic spindle.
