How do medications treat periungual warts?

Medications can be used to treat periungual warts. The medications are used to promote the creation of blisters which will push the warts up above the skin. Once the warts are elevated, a doctor can remove the rough skin of the wart.

Over-the-counter medications for periungual warts are usually made up of acids that gently burn off the area. Doctors have access to more aggressive medications. One option involves injecting warts with an immunotherapy medication that stimulates your immune system to attack warts. Another injection, called bleomycin, can be used to kill the virus that causes warts.
