Summary
Methylprednisolone raises blood glucose and can reduce the effectiveness of insulin, so higher insulin doses are often needed. Glucose control may deteriorate, and hypoglycemia may occur when the steroid is reduced or stopped.
What this interaction means in plain words
Insulin regular human 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
Corticosteroid-induced insulin resistance and increased hepatic gluconeogenesis oppose insulin action.
What to do
Monitor blood glucose more frequently and increase insulin as required during steroid therapy. Reduce insulin again as the steroid is tapered.
