Dexamethasone and Saxagliptin can affect each other. The combination is often manageable, but it may need a change of dose, a change of timing, or extra checks while both are taken.
Dexamethasone belongs to Endocrine; Saxagliptin belongs to Endocrine.
Why it happens
Glucocorticoid-induced insulin resistance opposes saxagliptin, with possible CYP3A4 induction.
