What Is Cantharone (Cantharidin)?

Cantharone is a topical solution that contains the active ingredient cantharidin, which is derived from the blister beetle. Cantharidin has blistering properties, making it useful in the treatment of certain skin conditions. It is commonly used to address issues such as warts and molluscum contagiosum. The application of Cantharone leads to the formation of a blister on the treated area, aiding in the removal of targeted skin lesions.

How Does It Work?

Cantharone works by causing blister formation on the skin. When applied topically, it acts as a blistering agent. The precise mechanism of action is not fully understood, but it is believed to irritate the skin and trigger the release of substances that lead to the formation of a blister. This blister helps to lift and separate the affected skin from the healthy tissue, promoting the removal of warts or other lesions. The process is typically performed by a healthcare professional to ensure proper application and minimize potential complications.

Cantharone Dosage, Usage, and Storage


In a 0.7% Cantharone solution, cantharidin makes up 0.7% of the total volume. The dosage of Cantharone 0.7% will be determined by your healthcare provider based on the specific condition being treated and the size and location of the lesions. The application is typically done in a healthcare setting by a qualified professional.

How to Use?

Cantharone 0.7% is usually applied directly to the affected area by a healthcare provider. The application is generally carried out with caution to avoid getting in touch with eyes, skin, and mucous membranes. The treated area is often covered with an occlusive dressing, and the solution is left on for a specific amount of time, after which the dressing is removed. After application, a blister will typically form, and the healthcare provider will monitor the healing process.

How to Store?

Cantharone should be stored at room temperature, away from direct sunlight and moisture. Keep the medication out of reach of children. Always check the expiration date before you buy Cantharone online and discard any expired medication.

Important Precautions 

  • Cantharone application should be performed by a qualified healthcare professional. Self-application is not recommended.
  • Dosage is individualized based on the patient’s condition. Follow the prescribed amount and frequency strictly.
  • Take care to apply Cantharone only to the affected area, avoiding contact with surrounding healthy skin.
  • Special caution is needed when treating children and the elderly. The dosage and application should be carefully determined.

Warnings for Cantharone Use

  • Monitor for signs of allergic reactions such as severe redness or swelling. Seek immediate medical attention if observed.
  • Avoid contact with the mucous membranes and eyes. Wash thoroughly with water if accidental exposure occurs.
  • Do not apply Cantharone to open wounds or broken skin. Ensure the skin is intact before application.
  • Consult with a healthcare provider before using Cantharone during pregnancy or breastfeeding, as its safety in these situations is not well-established.

Cantharone Side Effects

Some common side effects of Cantharone may include:

  1. Pain or a Burning Sensation
  2. Blistering of the skin
  3. Redness and swelling
  4. Itching
  5. Changes in skin pigmentation
  6. Painful Urination (if applied to genital warts)
  7. Scarring

Contact your healthcare provider immediately if you experience any unexpected or severe reactions, such as excessive pain, swelling, or signs of infection.

[Note: Cantharone should only be applied by a healthcare professional, as self-application or overuse can cause severe side effects].

Interactions of Cantharone 0.7% Topical Solution

As a topical treatment, the systemic absorption of cantharidin is minimal, and the likelihood of drug interactions is low. However, it’s still important to inform your healthcare provider about all the medications you are taking to ensure safety and efficacy. Here are some general considerations:

  1. If you are using other skin treatments, such as salicylic acid-based products or other wart treatments, discuss this with your healthcare provider. Using multiple treatments simultaneously may increase the risk of skin irritation.
  2. Inform your healthcare provider about any pre-existing medical conditions you may have, especially skin conditions or allergies. This information can help in assessing the suitability of Cantharone for your specific case.
