Warts often go away without treatment, but if a wart does not go away or is painful, a dermatologist can treat it using use cryotherapy, electrosurgery, or cantharidin, according to the American Academy of Dermatology. A dermatologist can also perform surgery to remove a nose wart.
Nose warts in children and adolescences often go away given time, but adults may opt for removal. The most common treatment for removing warts is cryotherapy, which involves freezing the wart, states the American Academy of Dermatology. This treatment may leave dark spots on patients with darker skin and often requires multiple treatments. Excision and curettage requires a dermatologist scraping the wart with a small scalpel or cutting the wart out entirely.
For warts that are harder to treat, a dermatologist may recommend laser treatment, notes the American Academy of Dermatology. This treatment involves numbing the wart with anesthesia and applying a laser directly to the wart on the nose or other body parts to burn it off. For warts that do not respond to traditional treatment, a dermatologist may recommend bleomycin, an anti-cancer medicine that may cause side effects such as nail loss if one injects it into the fingers.
Immunotherapy is another treatment for warts that do not respond to other treatments, explains the American Academy of Dermatology. It involves using a patient's immune system to remove the wart by creating an allergic reaction around the wart. The body should then fight the allergic reaction and remove the wart.
