Fucicort is a type of topical cream that is used to treat fungus. It uses fusidic acid and betamethasone in order to reduce inflammation and fight infections. Fucicort can be used for psoriasis, eczema, dermatitis, and lupus. Although it is effective in treating skin conditions, long term usage of the cream should be avoided. This is especially true for children and infants since they are particularly prone to systemic absorption, which can cause adrenal suppression.
