Summary
Systemic methylprednisolone raises blood glucose by increasing insulin resistance and hepatic glucose output. Patients using inhaled insulin may lose glycemic control and need dose increases.
What this interaction means in plain words
Insulin inhaled 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
Monitor blood glucose more frequently and adjust the inhaled insulin dose during corticosteroid therapy. Lower the dose when the corticosteroid is tapered.
