Introduction

For smaller warts with fewer in number and when the skin is less likely to develop irritation, tretinoin cream is suitable. It works by regulating the metabolism of keratinocytes, gradually causing the warts to shed. Long-term consistent use is required, and mild desquamation may occur during treatment, which does not affect normal daily activities. Imiquimod may be used for larger warts, multiple warts, or when the skin is sensitive. Neither medication should be used if the skin is broken or ulcerated.

Generally, when the filiform warts are small, few in number, and the skin has good tolerance, tretinoin cream can be used. When the warts are large, numerous, or the skin is sensitive, imiquimod may be used instead. However, if there is skin erosion or ulceration, neither of these medications should be applied. If any abnormalities occur, it is recommended to seek medical attention promptly. Detailed explanations are as follows:

When the warts are small, not numerous, and the skin is not prone to irritation, tretinoin cream is suitable. It works by regulating the metabolism of keratinocytes, gradually causing the warts to shed. Long-term consistent application is required. Mild peeling may occur during treatment, which does not affect normal daily activities. Continued use of the medication can achieve the desired therapeutic effect.

If the warts are large, numerous, or the skin has a strong tolerance to drug irritation, imiquimod can be selected. This medication stimulates a local immune response, accelerating the removal of warts. Its effect occurs relatively quickly, but local redness and swelling may appear. Patients with sensitive skin should use it with caution. If there is skin erosion or ulceration, both medications may irritate the wound surface, increasing pain or leading to infection, so they should not be used in such cases.

Before using medication to treat filiform warts, it is important to assess the skin condition, strictly follow the instructions for use, and discontinue the medication promptly and seek medical evaluation if significant discomfort occurs.

What are the simplest methods for removing filiform warts?

In general, there is no single "simplest method for removing filiform warts." Commonly used simple approaches include cryotherapy, laser therapy, topical medication application, electrocautery, and surgical excision, and the appropriate method should be selected based on the specific condition of the wart.

What ointment is used for treating filiform warts?

Tretinoin cream promotes the shedding of abnormally proliferated wart tissue by regulating epidermal cell differentiation. Apply a small amount evenly onto the surface of the wart once nightly. During the initial stages of treatment, localized skin redness and dryness may occur. After several weeks of consistent use, the wart may gradually shrink. If no significant improvement is observed after a period of medication, or if the warts are large in size or numerous, timely medical consultation is advised for consideration of physical treatments.
