Although most warts do typically go away on their own and may not require treatment, some do become painful, bothersome, rapidly spread, or don't go away, even after several years, and do need to be treated.
Wart TreatmentsThe most common treatments that your pediatrician will likely try include freezing the warts with liquid nitrogen, which is called cryotherapy, or applying cantharidin to the warts. Both treatments should cause some blistering of the wart, causing it to come off, although multiple treatments are often necessary. The cantharidin treatments have the benefit of usually being painless, although it can trigger a large, painful blister later that day.
Many parents try to treat their children's warts at home, which has become much easier now that home wart freezing kits are now available, such as Compound W Freeze Off, Dr. Scholl's Freeze Away Wart Remover, or Wartner Wart Removal System. In addition to home cryotherapy, another home remedy that many parents use involves applying salicylic acid to the warts, using OTC products such as Compound W Liquid Wart Remover or Dr. Scholl's Clear Away One Step Salicylic Acid Wart Remover.
Duct Tape for WartsAn increasingly popular home wart remedy involves applying duct tape to warts.
Using this duct tape treatment, you:
- cover the wart with duct tape for six days (if the duct tape comes off early, simply reapply it to the wart)
- next, remove the duct tape, soak the wart, and use an emery board or pumice stone to remove skin on top of the wart if possible
- reapply the duct tape after twenty-four hours and repeat the steps 1 and 2
Although a newer study reported results that were not as impressive for duct tape,3 there may have been problems with this study,4 and many people still recommend giving duct a try.
Duct Tape Method Treatment TipMany kids don't want to walk around with a gray piece of duct tape on their skin, especially if their wart is on their finger or some other part of their body that is easily visible.
Using duct tape in their favorite color, such as red, pink, or blue, can make the duct tape method for treating warts a lot easier for your kids to handle, especially since they may need to keep the duct tape on for a month or two.
