Imiquimod
"I stopped using the cream after the 4th day. I have followed the instructions to a T. Applied a minimal amount and rubbed it into the wart until it was gone, made sure that I did not apply it to normal skin. The cream actually burned through part of the wart and burned the epidermis so I've had to stop using the cream as it can not be applied to broken skin. The fingers that I used to apply the cream have experienced nerve pain and burning sensations similar to those I experienced where I applied the cream on the wart. I had hesitations about using this cream, however, at least I can say that I have tried it. I am going to stick to liquid nitrogen, the least painful form of treatment for me out of all the medical treatments I've tried."
