Summary
Systemic methylprednisolone raises blood glucose by increasing insulin resistance and hepatic glucose output. Patients on insulin may have worse glycemic control and need higher insulin doses.
What this interaction means in plain words
Insulin degludec / insulin aspart and Methylprednisolone 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 antagonize insulin action by promoting gluconeogenesis and peripheral insulin resistance.
What to do
Increase blood glucose monitoring and titrate insulin upward during corticosteroid therapy. Reduce insulin again as the corticosteroid is tapered to avoid hypoglycemia.
