Currently, no treatment can do so. Warts may heal and regrow. In other cases, the body may rid itself of the virus by destroying any remaining HPV cells after wart removal. No over-the-counter wart removal product contains liquid nitrogen. Instead, they contain a mixture of dimethyl ether, propane, and sometimes isobutane. Home freezing products may not be as effective as cryosurgery.
Though they contain the same acids that doctors use, the acids are at much lower concentrations, and their freezing chemicals are also less powerful. Home care products may be able to remove small warts, but they may only temporarily reduce the size or appearance of larger growths.
People sometimes use other methods, such as applying duct tape to the area for several weeks. However, these approaches have no or very slim scientific backing. Most people experience minor pain during cryosurgery and a burning sensation when the skin thaws afterward. During and immediately after the procedure, the treatment site may change color and swell.
There may also be soreness for a few days. About 24 hours after the procedure, a blister forms around the wart, and it resolves within 2 or 3 days. The entire recovery typically takes around a week, and it is important to keep the area clean, dry, and free from friction or pressure throughout this time. Usually, plantar warts, large warts, and those in areas with a lot of pressure or friction tend to cause the most pain and complications, such as scarring or tissue damage.
Other potential complications of cryosurgery include:. Dermatologists can reduce the risk of complications by limiting contact with liquid nitrogen to under 30 seconds. A secondary infection developing in the site of cryosurgery is uncommon. The symptoms include:.
Anyone with symptoms of a secondary infection should contact a doctor, who may prescribe a topical antiseptic or an oral antibiotic. Many w arts disappear without treatment. It may also be possible to remove small warts with over-the-counter products.
If warts are large, numerous, or persistent, it may be best to have them professionally removed. This is particularly beneficial for people with certain chronic conditions or weakened immune systems. To remove a wart, a dermatologist might use cryosurgery, or cryotherapy. This involves briefly applying liquid nitrogen to the skin. The healing period is about 1 week, and complications are rare, though they can occur.

In some cases, your doctor may be uncertain if your skin growth is a wart. If so, they may remove part of the wart to send to a laboratory for identification. Some warts can be prevented, others cannot. But warts also may be passed from person to person by touch. It is also possible to get warts from using towels or other objects that were used by a person who has warts. Warts on the genitals are very contagious and can be passed to another person during oral, vaginal, or anal sex.
It is important not to have unprotected sex if you or your partner have warts on the genital area. Warts also can grow on the cervix inside the vagina without a person knowing it.

You are here Home » Cryotherapy for Warts. Top of the page. Surgery Overview Cryotherapy involves freezing a wart using a very cold substance usually liquid nitrogen. Your doctor may trim the wart with a small knife before applying liquid nitrogen.
Cryotherapy is painful. A numbing local anesthetic is usually not needed but may be used in some cases. Your doctor applies the liquid nitrogen to the wart using a probe or a cotton swab. Liquid nitrogen can also be sprayed directly on the wart. Most warts require 1 to 4 treatments, with 1 to 3 weeks between each treatment.
Within hours after treatment, a blister may form. If the blister breaks, clean the area to prevent the spread of the wart virus. Avoid contact with the fluid, which may contain the wart virus. The blister will dry up over the next few days, and the wart may fall off. Multiple treatments may be needed to get rid of the wart.
Why It Is Done Cryotherapy is usually used if salicylic acid treatment has not eliminated a wart or if quick treatment is desired.
How Well It Works Cryotherapy can destroy warts. Risks If done carefully, cryotherapy poses little risk of scarring.
