Medications for warts are used to treat different types of warts. These medications also have other uses, such as treating certain skin conditions. They work by either boosting your immune system to fight the virus causing the warts or by peeling away the affected skin. Common classes include immune response modifiers and keratolytics. Immune response modifiers like imiquimod (Aldara) are usually applied as topical creams. Keratolytics, such as salicylic acid, come in various forms including topical gels and solutions. These options provide different ways to help you manage and treat warts effectively.
