Desowen Lotion is a topical steroid use for the treatment of skin conditions with inflammation and itching. It provides relief from swelling, redness, and itching in the affected area by inhibiting the release of substances that cause inflammation. Desowen Lotion is only meant for external use and should be used as advised by your doctor. You should normally wash and dry the affected area before applying a thin layer of the medicine. Avoid any contact with your eyes, nose, or mouth. Rinse it off with plenty of water in case of accidental contact. Avoid covering the treated area with airtight dressings such as bandages unless directed by a doctor.
