Thank you for trusting us with your care. Please find below the after-care home instructions for Cantharone treatment of your plantar wart.

What is Cantharone?

Cantharone is a topical medication commonly used for the treatment of warts. It contains cantharidin, a chemical derived from the blister beetle, which works by causing a blister to form underneath the wart. This blister lifts the wart away from the skin, allowing for its removal. Proper aftercare is crucial to ensure effective treatment and prevent complications.

Immediate Post-Application Care

  1. Cover the Treated Area: The treated wart will be covered with a bandage or tape. This dressing should remain in place overnight unless otherwise directed by your healthcare provider.
  2. Avoid Wetting the Area: Keep the treated area dry. If necessary, you can shower but avoid soaking the area. Protect the treated area with a waterproof covering during bathing.

Next Morning After Application

  1. Remove the Dressing: Carefully remove the bandage or tape after 24 hours. Gently clean the area with soap and water.
  2. Observe the Area: You will likely see a blister forming beneath the wart. This is a normal reaction to the medication.

Managing the Blister

  1. Do Not Pop the Blister: It is important to leave the blister intact. Popping it can increase the risk of infection and delay healing.
  2. Keep the Area Clean: Wash the area gently with soap and water. Pat it dry with a clean towel.
  3. Apply Antibacterial Ointment: Use an over-the-counter antibacterial ointment like Neosporin to prevent infection. Apply a thin layer over the blister and cover with a clean bandage.
  4. Change the Dressing Daily: Apply a Bandaid the next day and change it on daily basis. 

Pain Management

  1. Over-the-Counter Pain Relief: You may experience some discomfort or pain. Over-the-counter pain relievers like acetaminophen or ibuprofen can help manage this. Follow the dosage instructions on the package.
  2. Avoid Pressure on the Area: Try to avoid putting pressure on the treated area. For warts on the feet, wear comfortable shoes that do not rub against the blister.

Monitoring for Infection

  1. Signs of Infection: Watch for signs of infection, such as increased redness, swelling, warmth, or pus. If any of these symptoms occur, contact your healthcare provider immediately.
  2. Continued Discomfort or Complications: If the blister becomes very painful, bursts, or you notice any unusual changes, seek medical advice promptly.

Follow-Up Care

  1. Scheduled Appointments: Please be sure to follow up with me in two weeks or sooner if problems arise. 
  2. Additional Treatments: Depending on the size and persistence of the wart, additional treatments may be necessary. We will make recommendations for any further applications of Cantharone or other treatments on your next follow up visit. 

General Tips

  1. Avoid Picking or Scratching: Do not pick at or scratch the treated area, as this can cause irritation or spread the virus that causes warts.
  2. Preventing Spread: Wash your hands thoroughly after touching the treated area. Avoid sharing towels, socks, or shoes to prevent spreading the virus to others.
  3. Footwear: If the wart was on your foot, wear clean, breathable socks and change them daily. Ensure your footwear is clean and dry.

By following these instructions carefully, you can help ensure the effective removal of the wart and promote healthy healing of the treated area. If you have any questions or concerns during your recovery, do not hesitate to contact us at 623.439.2200.
