I found using Aldara to clear up the majority of
warts, and then using a different
treatment (such as cryo) to clear any remaining
warts seemed to be effective. I used a combination of TCA and Aldara, and have been wart free for a month now (took 3 months to entirely clear). Aldara has some discomfort associated with it, but I found it less painful than TCA (though much more itchy!). Any treatment for genital warts is uncomfortable though.
