Summary
Thiazide diuretics can raise blood glucose and worsen glycemic control in diabetes. Insulin needs may therefore increase after a thiazide is started.
What this interaction means in plain words
Insulin degludec-insulin aspart and Methyclothiazide 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
Thiazides impair glucose tolerance, partly via hypokalemia-related reduction in insulin secretion and increased insulin resistance.
What to do
Monitor blood glucose and serum potassium after starting the thiazide. Adjust the insulin dose if needed and correct hypokalemia.
