Cryotherapy

Your doctor can freeze off your warts using liquid nitrogen in a treatment called cryotherapy. You can have this treatment every one to three weeks depending on how quickly the area heals after each treatment and what happens to your warts.

Two RCTs found that cryotherapy worked about as well as treatment with acid. After six weeks of either treatment, about two-thirds of people had gotten rid of their warts.22 Warts came back in about one-third of people two months later, whichever treatment they had.

It isn’t clear whether cryosurgery works better than using an electrical current (electrosurgery) to get rid of the warts.

Cryotherapy can sometimes cause an infection, but this is rare.

It is safe to have cryotherapy if you’re pregnant.
