Dexamethasone Pharmacology

Dexamethasone has numerous possible indications such as asthma, chemotherapy-induced nausea and vomiting, and pain associated with inflammation. Dexamethasone is more potent than prednisone. Approximately 0.75 mg of dexamethasone is equivalent to 5 mg of prednisone. When using dexamethasone, recall that it can raise blood sugars. Monitor this closely in patients with diabetes. A dexamethasone suppression test helps detect excessive endogenous production of cortisol.
