Imiquimod (Aldara) for Warts
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.
