What Podophyllin Dosage Can I Use For Recurring Genital Warts If Podowart Once Weekly Isn T Working?

Hi, i am a 30year old virgin girl. Last year I had observed few outgrowths near my vaginal hole, i tested negative for the high risk hpv strains, bt the gynac told me those were warts and told ne to apply podowart once a week. But the warts keep coming back... can you please suggest some alternate creams or the proper dosage of podophyllin so that the warts disappear completely?
