Apply sparingly to the affected area once or twice daily until improvement occurs. As with other highly active topical steroid praparatlons, therapy should be discontinued when control is achieved. If longer course is necessary, it is racommanded that treatment should not be continued for more than four weeks without the patients condition being observed. Repeated short course of Dermatas may be used to control exacerbations. If continuous steroid treatmant is necassary a less potent preparation should be uaed. In very resistant lesions, especially where there is hyperkeratosis, the anti-inflammatory effect of Dermatas can be enhanced, if necessary, by occluding the treatment area with polythene film. Only overnight occlusion is usually adequate to bring about a satisfactory response. Thereafter, improvement can usually be maintained by application without occlusion.
