Imiquimod Topical

Conditions Treated

Imiquimod cream is used to treat certain types of actinic keratoses (flat, scaly growths on the skin caused by too much sun exposure) on the face or scalp. Imiquimod cream is also used to treat superficial basal cell carcinoma (a type of skin cancer) on the trunk, neck, arms, hands, legs, or feet and warts on the skin of the genital and anal areas. Imiquimod is in a class of medications called immune response modifiers. It treats genital and anal warts by increasing the activity of the body's immune system. It is not known exactly how imiquimod cream works to treat actinic keratoses or superficial basal cell carcinoma. Imiquimod cream does not cure warts, and new warts may appear during treatment. It is not known whether imiquimod cream prevents the spread of warts to other people.
