Summary
Miglitol slows carbohydrate absorption and adds to insulin's glucose-lowering effect. If hypoglycemia occurs, it must be treated with glucose rather than sucrose because absorption of table sugar is delayed.
What this interaction means in plain words
Insulin isophane protamine 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.
Insulin isophane protamine human belongs to Endocrine; Miglitol belongs to Endocrine.
Why it happens
Alpha-glucosidase inhibition delays intestinal carbohydrate absorption, adding to insulin's effect and impairing sucrose digestion.

Monitor glucose and reduce the insulin dose if needed. Instruct patients to treat hypoglycemia with oral glucose (dextrose) rather than sucrose.
