Imiquimod cream can treat filiform warts. Filiform warts are a type of human papillomavirus (HPV) infection. When infected with this virus, the long-term effect of the virus on the skin causes the skin tissue to proliferate and form warts. Topical imiquimod cream has the ability to inhibit tissue proliferation. A small amount applied to warts can inhibit the proliferation of wart tissue; a large amount applied has a certain corrosive effect on the proliferating tissue. Since the drug has a certain corrosive effect, it is recommended to use the drug strictly according to the instructions for use of the drug. If the warts are large, it is recommended that the warts be treated with laser first, and then the medicine should be used to prevent recurrence. Filiform warts are recommended to consult a dermatologist, under the guidance of the doctor targeted treatment.
