Summary
Cortisone is a glucocorticoid that raises blood glucose by promoting gluconeogenesis and insulin resistance. It can therefore weaken the glucose-lowering effect of glimepiride and pioglitazone, with worsening control particularly during higher-dose or prolonged courses.
What this interaction means in plain words
Cortisone and Glimepiride-pioglitazone 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
Glucocorticoid-induced insulin resistance and increased hepatic glucose output oppose the effects of sulfonylureas and thiazolidinediones (pharmacodynamic antagonism).
What to do
Monitor blood glucose more frequently during corticosteroid therapy and increase antidiabetic doses if needed. Reduce the doses again when the corticosteroid is tapered or stopped to avoid hypoglycemia.
What to ask your pharmacist
