DEXAMETHASONE VIATRIS contains the active ingredient dexamethasone phosphate (as sodium). Dexamethasone phosphate (as sodium) is a glucocorticoid and belongs to a group of medicines called corticosteroids. It may be used to treat an inactive or underactive adrenal gland or to treat a number of different diseases such as certain immune disorders and skin problems, asthma or arthritis. Corticosteroids reduce inflammation, one of the body’s reactions to injury. Except for its use in the treatment of underactive adrenal glands, dexamethasone phosphate (as sodium) does not cure disease; it treats the symptoms.
