A novel form of steroid treatment called Betesil is an adhesive plaster which contains a potent steroid. Recent studies show this is particularly suitable for individual stubborn or difficult to treat plaques of psoriasis such as those which can occur on the knees, shins and elbows. The medicated plaster is placed over the plaque, left for 24 hours and then renewed. The occlusive effect of the plaster improves moisturisation and assists the effect of the steroid giving localised improved benefit. A second, less potent version with a less potent steroid is Haelan.
The . Food and Drug Administration (FDA) has approved two drugs, Protopic and Elidel, for the treatment of eczema which many dermatologists have found work well for treating psoriasis on the face or other sensitive areas. Medication used to treat facial psoriasis should applied carefully and sparingly; creams and ointments can irritate eyes. Because facial skin is delicate, prolonged use of steroids may cause it to become thin, shiny and/or prone to enlarged capillaries. Treatment with steroids may be safe if a careful treatment schedule is followed.
