Summary
Prednisone raises blood glucose, particularly postprandially, and can reduce the effect of insulin aspart. Insulin needs often rise during steroid therapy and fall after it is reduced or stopped.
What this interaction means in plain words
Insulin aspart and Prednisone 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.
Insulin aspart belongs to Endocrine; Prednisone belongs to Endocrine.
Why it happens
Glucocorticoid-induced insulin resistance and increased hepatic gluconeogenesis oppose insulin action.
What to do
Monitor glucose frequently and titrate insulin upward during steroid therapy. Reduce insulin as prednisone is tapered to avoid hypoglycemia.
