If you cover the wart with a piece of duct tape and leave it in place for two weeks, then peel it off, the wart should be gone, according to my husband's doctor. I was surprised, thought that an old wive's tale, but it would be worth it if you don't want to use the Freeze Away.
Call your doctor. He or she should be able to tell you if it's safe to use. If it's not safe, ask if there's anything else you can do. That way you wont be taking any chances.
