How to Use Freezing to Treat Plantar Warts

Freezing, or cryotherapy, is one of the most popular methods used today to treat plantar warts on the feet, heels and on the balls of the feet. Cryotherapy is done by freezing lesions with liquid nitrogen or other cryogens. This method is traditionally done in a doctor's office. However, some products sold over the counter work very well on less stubborn growths.

Instructions

  1. Use Freezing to Treat Plantar Warts

    • 1

      See your dermatologist for prescribed cryotherapy. Using an applicator, your doctor will apply the nitrogen (at a temperature of -196 C) directly to the lesions for a few seconds and repeat the process several times. Initially, the treatment will produce a burning sensation, but it will pass within seconds.

    • 2

      Purchase a home freezing kit to treat yourself. These kits are inexpensive and contain multiple applications. They can usually be found at a local grocery store or pharmacy.

    • 3

      Place the applicator into the freeze component and twist. Immediately after removal, place the tip of the applicator onto the plantar wart, holding it in place for several seconds.

    • 4

      Wash the treated area with antibacterial soap and water, then dry thoroughly and place a bandage on top. Some blistering may occur.

    • 5

      Use a topical antiseptic purchased from a pharmacy if blistering occurs. Apply a small amount of antiseptic directly onto the blister and cover with a bandage. Once the blister dries out, it will scab up and fall off.

    • 6

      Repeat the treatments if necessary. Many plantar warts require multiple freezing applications to completely disappear.

    • 7

      Take an antibiotic if an infection occurs. During the freezing process, some people experience infections within the lesions. While the plantar wart itself is caused by a virus, the surrounding area may become infected. This infection can adequately be treated by using antibiotics prescribed by a physician.
