What DBL Dexamethasone Sodium Phosphate Injection is used for

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.

Your doctor may have prescribed DBL Dexamethasone Sodium Phosphate Injection for another reason. Ask your doctor if you have any questions about why DBL Dexamethasone Sodium Phosphate Injection has been prescribed for you.

DBL Dexamethasone Sodium Phosphate Injection is not addictive.

This medicine is available only with a doctor’s prescription.
