Candid B cream contains beclomethasone 0.025% w/w and clotrimazole which is used in the treatment of skin infections. Beclometasone is a steroid which blocks the production of certain chemical messengers (prostaglandins) that make the skin red, swollen and itchy. Clotrimazole is an antifungal which stops the growth of fungi on the skin by preventing them from forming their own protective covering.
