How It Works
Imiquimod is a form of immunotherapy. Immunotherapy triggers your immune system to fight the virus causing the wart. This may destroy or shrink the wart.
Imiquimod is thought to work by helping the body's immune system fight viruses, including the human papillomavirus (HPV) that causes warts. It also may shrink the warts.
Why It Is Used
Imiquimod has been approved for use on genital warts and can be used for difficult-to-treat common warts. It may be used at home after a health professional teaches you how to apply it.
How Well It Works
Whether imiquimod is an effective treatment for common warts is not yet known. It does appear to be effective in curing genital warts.1

What To Think About

Wash your hands after applying imiquimod cream, because it may cause skin irritation.
Imiquimod may be used on warts that are resistant to other treatments. It is generally used when other treatments have failed.
