How long does cryotherapy take to work for warts?

Cryotherapy freezes the wart tissue. Redness, tenderness, swelling, a blister, or a dark crust can occur as the treated area reacts. The surface then dries and separates while new skin forms underneath. A wart can look more prominent before it begins to shrink, so an early appearance is not a reliable sign that treatment has failed.

The number of sessions depends on the wart's site, thickness, size, and response. Warts on thicker skin may be slower to change. A clinician may review the area before deciding whether another session or a different approach is appropriate.

Follow the clinic's instructions for cleaning, dressings, and pain relief. Keep the area protected from rubbing, especially when the wart is on a foot, hand, or another high-contact site. Do not puncture a blister or pull off a crust unless instructed. Wash your hands after touching the area and avoid sharing towels or personal nail tools.

Return for the planned review even if the wart looks smaller. A remaining rough spot may be healing tissue or wart tissue, and examination helps distinguish them.

Contact the clinic if pain, swelling, warmth, or redness is worsening, if pus or spreading redness appears, or if you develop a fever. Seek review if the treated area does not heal, bleeds repeatedly, or the diagnosis was uncertain. People with diabetes, poor circulation, reduced sensation, or a weakened immune system should follow their clinician's specific threshold for contacting the clinic.

Ask when the wart should be checked, how to protect a blister, whether you can use swimming pools or shared changing areas during healing, and what signs suggest infection. Ask what the next option would be if the wart remains after the planned review.
