Summary
Prednisolone causes insulin resistance and raises blood glucose, so insulin requirements often increase during steroid therapy. Postprandial hyperglycemia is typical, especially after morning dosing.
What this interaction means in plain words
Insulin aspart and Prednisolone 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; Prednisolone belongs to Endocrine.
Why it happens

What to do
