Mometasone is classed as a potent topical corticosteroid. Topical corticosteroids are also referred to as topical steroids . Topical steroids are used in addition to moisturisers (emollients) for treating inflammatory skin conditions such as eczema and dermatitis . A topical steroid is used when patches of eczema or dermatitis flare up. Mometasone relieves the symptoms of a flare-up by reducing inflammation, itching and redness. It is not a cure for the condition, but it will help to relieve the symptoms. Short courses of mometasone may also be prescribed for the treatment of psoriasis for small areas such as the scalp, soles of the feet, or palms of the hands.
