Topical corticosteroids are used to treat skin conditions such as eczema, psoriasis, and dermatitis. They also have other uses, such as reducing itching and swelling caused by an allergic reaction. These medications work by reducing inflammation and lowering the immune response where they are applied. Topical corticosteroids come in various forms, such as creams, ointments, and lotions. Examples include clobetasol (Clobex, Olux), betamethasone dipropionate (Diprolene, Luxiq), and fluocinonide (Vanos).
