Summary
Corticosteroids cause insulin resistance and increase hepatic glucose production, raising blood glucose and increasing insulin requirements. Hyperglycemia can be marked, particularly after meals, with higher steroid doses.
What this interaction means in plain words
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.
Insulin aspart belongs to Endocrine; Methylprednisolone belongs to Endocrine.
Why it happens
Pharmacodynamic antagonism through glucocorticoid-induced insulin resistance and increased gluconeogenesis.
What to do
