Effective Treatments for Viral Warts: Options and Considerations - Dermatology

More Info

---

Viral warts, caused by the human papillomavirus (HPV), can be persistent and challenging to treat. Your experience with cryotherapy and topical treatments like Cantharidin (康言軟膏) is common, and it's not unusual for warts to spread or persist despite treatment. Let's address your questions one by one.

1. Switching to Electrosurgery or Laser Treatment: If you've been undergoing cryotherapy for three months without significant improvement, it might be worth considering alternative treatments such as electrosurgery or laser therapy. Electrosurgery uses high-frequency electrical currents to destroy wart tissue, while laser therapy targets the blood vessels that supply the wart, effectively cutting off its blood supply. Both methods can be more effective for stubborn warts, especially if they are extensive or have spread. However, the choice of treatment should be made in consultation with a dermatologist, who can assess the specific characteristics of your warts and recommend the most suitable option.

2. Duration of Cryotherapy Treatment: The duration of cryotherapy treatment can vary widely among individuals. Some patients may see improvement within a few weeks, while others may require several months of consistent treatment. Factors such as the size, location, and number of warts, as well as the individual's immune response, can influence healing time. If you continue with cryotherapy, it's essential to follow your dermatologist's recommendations and be patient, as it may take several sessions to achieve complete resolution.

3. SADBE Treatment: Squaric acid dibutyl ester (SADBE) is indeed a treatment option for warts that has shown promising results. It works by inducing a local immune response against the HPV virus. While SADBE is used in some countries, its availability can vary. In Taiwan, you would need to consult with a dermatologist to see if this treatment is offered in your area. If it is available, it could be a viable option, especially if other treatments have failed.

4. Preventing Spread During Daily Activities: It's understandable to be concerned about spreading the virus, especially when engaging in activities like cooking and cleaning. While warts are contagious, the risk of spreading them through normal daily activities is relatively low, especially if you maintain good hygiene practices, such as washing your hands thoroughly after touching the warts. However, it's advisable to avoid picking at or scratching the warts, as this can lead to further spread. If you have warts on your hands, wearing gloves while cleaning or cooking might provide an additional layer of protection.

In summary, if your current treatment is not yielding results, discussing alternative options like electrosurgery, laser therapy, or SADBE with your dermatologist would be prudent. Additionally, maintaining good hygiene and avoiding trauma to the warts can help minimize the risk of spreading the virus. Remember, patience is key in wart treatment, and finding the right approach may take some time. Always consult with a healthcare professional for personalized advice tailored to your specific situation.
