What is imiquimod?

Imiquimod is a topical immune response modifier used primarily to treat certain skin conditions, including superficial basal cell carcinoma, actinic keratosis, and genital warts. It works by stimulating the immune system to produce interferon and other cytokines, enhancing the body's ability to fight off abnormal cells and infections. Imiquimod is typically applied directly to the affected area and is available in cream form. Common side effects may include redness, irritation, and peeling at the application site.
