Summary
Miglitol slows carbohydrate absorption and lowers postprandial glucose, adding to insulin's effect and increasing hypoglycemia risk. Because miglitol blocks disaccharide digestion, hypoglycemia must be treated with glucose rather than sucrose.
What this interaction means in plain words
Insulin aspart 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 aspart belongs to Endocrine; Miglitol belongs to Endocrine.
