Generally, if one has a functioning immune system no treatment is needed and the bumps and virus will go away within 6–12 months of contraction. However, treatment is suggested if the bumps are on the genital area or if the person affected is immunocompromised. In healthy (non-immunocompromised) individuals, cryotherapy, curettage, laser therapy, oral therapy, or a topical therapy is suggested to treat the lesions. Cryotherapy involves freezing the lesions with liquid nitrogen, whereas curettage involves piercing the core and scraping the lesion with sterile equipment. Laser therapy involves destroying the lesion with a laser. It is a good idea to not try removing the lesions yourself, as the skin can become infected and the virus can spread to other parts of the body. A commonly prescribed oral medication used to treat the lesions is cimetidine and a topical therapy is Podophyllotoxin cream . (0.5%). Bathing in 1 kg of salt or swimming in the sea can have positive effects.
