Once discoid eczema has developed, the skin can become very red, itchy and inflamed – if this happens, your doctor may prescribe a steroid, with a cream or ointment base, to apply to the affected areas to help them clear up. The potency of the steroid used will depend on the severity of the eczema. Generally, for adults with discoid eczema, a more potent steroid will be used for longer periods, . 2–4 weeks depending on the area of the body. Children with discoid eczema will be prescribed topical steroids according to their age, and these may be moderate or potent.
