What is the best ointment for treating filiform warts?

Generally speaking, there is no definitive answer to the question of "what ointment is best for treating filiform warts," as the effectiveness of medication may vary from person to person. Commonly used topical medications include tretinoin cream, imiquimod cream, fluorouracil ointment, salicylic acid ointment, and interferon gel, which should be appropriately selected based on individual circumstances. Detailed explanations are as follows:

1. Tretinoin Cream: Works by regulating epidermal cell growth and promoting wart shedding. Apply a small amount to the surface of the wart once nightly. It may take several weeks to see results, and some people may experience initial side effects such as localized skin redness and dryness.

2. Imiquimod Cream: An immune response modifier that activates the local immune system to eliminate the virus. Apply 2-3 times weekly before bedtime and wash off the next morning. Suitable for cases with fewer warts. It works relatively slowly but has less irritation.

3. Fluorouracil Ointment: Inhibits cell proliferation and destroys wart tissue. Apply directly to the wart 1-2 times daily, taking care to avoid contact with normal skin to prevent pigmentation or skin irritation.

4. Salicylic Acid Ointment: Softens the stratum corneum and exfoliates the epidermis to remove warts. Select an appropriate concentration based on the size of the wart and apply 1-2 times daily. Surrounding healthy skin should be protected to prevent excessive corrosion.

5. Interferon Gel: Possesses antiviral and immunomodulatory effects, inhibiting viral replication. Apply evenly over the wart 2-3 times daily. It is commonly used as an adjunctive treatment to reduce the recurrence rate.

Topical ointments are only suitable for small and limited filiform warts and must be used under professional guidance. If the warts are large in size, numerous, or show no improvement after medication, timely medical consultation is recommended for physical treatments such as cryotherapy or laser therapy. Monitor skin reactions during treatment, and discontinue use immediately and consult a doctor if severe redness, swelling, or pain occurs.
