Treat plantar warts with self-care methods such as over-the-counter medications and smoke, recommends Mayo Clinic. Use stronger treatments such as prescription-strength medications, surgical procedures and the human papillomavirus vaccine if self-care treatments are ineffective.
Nonprescription wart medicines come in liquid or patch form and treat plantar warts with salicylic acid. Soak the plantar wart for 20 minutes, and then gently remove dead skin with an emery board or pumice stone before applying the patch or solution, notes Mayo Clinic. Use liquid applications twice a day and change patches every 48 hours to begin seeing results within weeks.
There are mixed results for using duct tape to treat plantar warts. Mayo Clinic suggests covering the wart with silver duct tape for six days before removing dead skin with an emery board or pumice stone. Repeat the process until the wart disappears. Smoke treatments are performed by surrounding the wart with the smoke of Populus euphratica leaves.
Use a surgical procedure if other remedies do not work, explains Mayo Clinic. These minor procedures involve a doctor cutting away the wart with an electric needle or using a laser to burn away the wart. Both surgeries cause scarring and are not typically used to treat plantar warts.
