As a wart remover, liquid nitrogen works by freezing the tissue of the wart, causing it to die and to fall off. It is extremely cold, and because of how it works, it is called cryotherapy. Some people may find it to be painful. It may take several treatments over a period of a few weeks to remove a wart, and it is used when other wart treatments haven’t worked. Liquid nitrogen for warts is applied by doctors in their offices, and the application takes less than a minute.

Liquid nitrogen warts removalLiquid nitrogen is usually applied by doctors during short office visits. The doctor may first prepare the wart by trimming it with a pair of scissors or a small knife. He or she then will apply the liquid nitrogen to the wart’s surface. The total time involved with applying liquid nitrogen is normally less than a minute. In some cases, the doctor may use a numbing local anesthetic. An anesthetic is not always necessary, however. Most people are able to tolerate liquid nitrogen applications.

The over-the-counter wart freeze-off treatments may require more applications and are not as effective as liquid nitrogen.

The doctor may spray the liquid nitrogen on or apply it with a probe or cotton swab. The wart will then be covered with a bandage. It will gradually change colors and then fall off. It may take up to four treatments to get rid of very thick warts over a period of weeks. It is fairly common for people to develop a blood blister after freezing wart off. If you do, apply a plaster over the wart frozen off blister and cover it. When it pops, clean the area and try to avoid spreading the fluid to the surrounding skin so that the wart virus does not spread.

Are there any side effects?

While most people find the application of liquid nitrogen to be mildly uncomfortable, small children or people who have low pain tolerances may need a topical anesthetic to numb the skin. The primary side effects are soreness and swelling. Many people also form a wart blood blister over the surface of the wart. When the skin is frozen, a blister forms underneath the wart, leaving the abnormal tissue on the surface so that it can peel away.

A blood blister that forms over the top is a secondary blister. It is harmless, so you should not be concerned by a blood blister. There is a potential for blood blisters to become infected.

If this happens, you will want to see your doctor for possible antibiotic treatment.

Finally, some people who have treated their warts with liquid nitrogen may have a pale skin discoloration that remains behind. Do you want to learn about using colloidal silver for warts? Read this article to learn more.
