Most warts go away on their own within several months to years, so treatment may not be needed for many children. In general, surgical excision and cautery are no longer recommended in most instances or covered by insurance plans, as they have been shown to increase the likelihood of localized spread. There is no treatment guaranteed to cure warts. If your primary care provider recommends treatment, it is important that you follow the instructions exactly as suggested. In general, using two or more treatments at a time is more likely to be successful.
Initial treatment with topical salicylic acid and medical tape is usually recommended. Solutions of 17 percent salicylic acid are readily available over-the-counter (Compound W, etc.). First, soak warts for 5 minutes in hot water (no hotter than 110° F). Pat area dry with towel. Gently file down the wart by removing layers of dead skin with a callus file, emery board or pumice stone. Remember to use only the file or pumice stone on the wart and not on other skin areas in order to prevent spreading the warts. Then the 17 percent salicylic acid should be applied to completely cover the wart. Once the salicylic acid 17 percent is dry, the wart should be covered with air-tight, white cloth surgical tape (may also be purchased at a drug store / pharmacy). You may also use household duct tape. Every 1 to 3 days when the tape loosens or falls off, it should be removed and more 17 percent salicylic acid and tape applied until the wart is gone. If the treated skin gets irritated, stop treatment for a few days until the skin feels better, then restart if the wart is still present. Be patient! Treatment may take several months. It is important to remain consistent with treatment for best results.
Sometimes, once one or a few warts start to go away, any other warts present will also soon go away.
