A small quantity of Medobeta should be applied to the affected area two or three times daily until improvement occurs.
Betamethasone cream is especially appropriate for moist or weeping surfaces and Betamethasone ointment for dry, lichenified or scaly lesions, but this is not invariably so.
In the more resistant lesions, such as the thickened plaques of psoriasis on elbows and knees, the effect of Betamethasone can be enhanced, if necessary, by occluding the treatment area with polythene film. Overnight occlusion only is usually adequate to bring about a satisfactory response in such lesions; thereafter, improvement can usually be maintained by regular application without occlusion.
