Full Consumer Medicine Information (CMI)

This leaflet provides important information about using DBL Dexamethasone Sodium Phosphate Injection. You should also speak to your doctor or pharmacist if you would like further information or if you have any concerns or questions about using DBL Dexamethasone Sodium Phosphate Injection.
Where to find information in this leaflet:

1. Why am I being treated with DBL Dexamethasone Sodium Phosphate Injection?

DBL Dexamethasone Sodium Phosphate Injection contains the active ingredient dexamethasone sodium phosphate. DBL Dexamethasone Sodium Phosphate Injection is a glucocorticoid and belongs to a group of medicines called corticosteroids.
DBL Dexamethasone Sodium Phosphate Injection may be used to treat an inactive or underactive adrenal gland or to treat a number of different conditions such as certain immune disorders; skin, lung, gastrointestinal, eye and blood problems; asthma; arthritis; or certain cancers or conditions associated with cancers. It may also be used to treat a buildup of fluid and before or after surgery to assist with the treatment of shock.
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 the condition, 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.
