Summary
Dexamethasone raises blood glucose and can counteract the glucose-lowering effect of exenatide. Glycemic control may worsen during steroid courses.
What this interaction means in plain words
Dexamethasone and Exenatide injectable 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.
Why it happens
Glucocorticoids increase hepatic gluconeogenesis and insulin resistance, opposing the incretin-mediated glucose lowering of exenatide.
What to do
Monitor blood glucose more frequently during dexamethasone therapy and adjust antidiabetic therapy as needed, then reassess when the steroid is tapered.
