Summary
Triamcinolone can raise blood glucose and reduce the effect of insulin, with hyperglycemia lasting days after an injection. Insulin requirements may increase and then fall again as the steroid effect wears off.
What this interaction means in plain words
Insulin degludec / insulin aspart and Triamcinolone 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
Corticosteroids increase hepatic gluconeogenesis and cause peripheral insulin resistance, opposing insulin action.
What to do
Monitor blood glucose closely after dosing and increase insulin as needed. Reduce the dose again when the steroid effect wanes.
