Summary
Miglitol and regular insulin both lower postprandial glucose, so the combination increases the risk of hypoglycemia. Because miglitol slows sucrose absorption, standard sugar-based rescue may fail.
What this interaction means in plain words
Insulin regular human and Miglitol 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
Additive pharmacodynamic glucose lowering from alpha-glucosidase inhibition plus insulin action.
What to do
Monitor blood glucose and reduce the insulin dose if hypoglycemia occurs. Treat low glucose with dextrose or glucagon, not sucrose.
What to ask your pharmacist
