Summary
Thiazide diuretics can raise blood glucose and reduce the glycemic control achieved with insulin. The effect is generally modest and dose related.
What this interaction means in plain words
Insulin lispro 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 reduce insulin secretion and sensitivity, partly through potassium depletion, opposing insulin action.
What to do
Monitor blood glucose and potassium when starting or adjusting the thiazide. Increase the insulin lispro dose if hyperglycemia develops.
