Cryotherapy Wart Removal


Cryotherapy wart removal is a procedure to remove your wart by freezing it. This is done using a cryogen (freezing chemical), usually liquid nitrogen.


Before your procedure:

  • Write down the correct date, time, and location of your procedure.
  • You or a close family member will be asked to sign a legal document called a consent form. It gives caregivers permission to do the procedure or surgery. It also explains the problems that may happen, and your choices. Make sure all your questions are answered before you sign this form.


What will happen:

Your caregiver will numb your skin and remove any dead skin on your wart. He will then use a cotton swab, spray, or cryoprobe (long, pointed device) to apply the cryogen to your wart. It may take up to 60 seconds for the wart to freeze. The frozen tissue will then be allowed to thaw slowly. A second application may be applied after a few minutes. How long the treatment takes will depend on the size of your wart and the area being treated.

After your procedure:

You may see a small ring of ice around your wart. Your caregiver may cover it with a bandage to keep it clean and dry. When the procedure is over, you may be able to go home. You may have pain in the treated area after the procedure. In a few weeks, the dead wart tissue may dry up and fall off.


  • You cannot make it to your appointment on time.
  • You have questions or concerns about your procedure.

Seek Care Immediately if

  • You have worsening pain or bleeding that does not stop.


Cryotherapy may be painful and cause blisters, scarring, or an open sore at the treatment area. The part of your skin that was treated may darken or lighten. Even after the procedure, the wart may not completely go away or may come back. Sometimes, treatment of genital warts may cause pain that does not go away. Without treatment, your wart may grow in size or number and become painful or bleed. The wart may spread to other parts of your body. Genital warts may cause problems with having sex and you may pass it on to another person.
