One common wart treatment used by dermatologists is cryotherapy, states the American Academy of Dermatolgy, during which the doctor freezes the warts using liquid nitrogen. Excision is another simple dermatological wart treatment.
Another method involves applying a topical drug to the wart that causes a blister to form underneath, at which point the wart is clipped away by the doctor. Some other treatments for warts that a dermatologist can administer include electrosurgery, curettage, chemical peels and laser therapy. Some doctors employ immunotherapy to help stimulate a patient's own immune system to eliminate warts, states the American Academy of Dermatology.
Patches and medications for treating warts can be found at most drug stores. These products work for many people, and are fairly inexpensive. Experts from Mayo Clinic say to look for formulas or patches containing 17 percent salicylic acid for best results. A home remedy that has worked for some people involves covering the warts with a piece of duct tape for six days. Upon removal, the warts are soaked in water and then filed down with an emery board or pumice stone.
Warts are caused by a virus and, though they are not harmful, there is no known cure. Because of this fact, most treatment methods require ongoing care, says Mayo Clinic.
