Imiquimod cream can be used clinically to remove flat warts. This cream is applied in a 5% formulation, mainly as an ointment preparation applied directly topically to the infected flat wart area. It can be applied about three times a week, mostly once a day, directly to the skin area. The mechanism of action is mainly to induce alpha interferon in the infected cells, thus directly antiviral, to play such a role. However, due to individual differences, some people are not sensitive to Imiquimod cream, so the results are not too satisfactory in the treatment of flat warts for some people. This is the time when you can use other treatment modalities, such as treatment with immunomodulators, such as interferon injections, etc.
