Lifestyle and home remediesBy Mayo Clinic staff
The following self-care approaches can help you treat plantar warts. Do not treat plantar warts at home if you have an impaired immune system, diabetes or nerve damage in your feet. Over-the-counter treatment options include the following:
- Salicylic acid. Nonprescription wart medications with salicylic acid are sold as a patch or liquid that destroys and peels off layers of infected skin a little bit at a time. Usually, you're instructed to wash the site, soak the wart for up to 20 minutes, gently remove dead tissue with a pumice stone or emery board, and apply the solution or patch. Patches are usually changed every 48 hours. Liquid applications are usually used twice a day. You may need to repeat this process for several weeks to eliminate warts completely.
- Freezing (cryotherapy) products. Products that freeze plantar warts, such as Compound W Freeze Off or Dr. Scholl's Freeze Away Wart Remover, are available at drugstores without a prescription. Such products aren't as effective as cryotherapy done at the doctor's office because they don't freeze tissue at a temperature as low as that achieved with liquid nitrogen. The treatment may also result in some pain.
