Summary
Miglitol lowers postprandial glucose and adds to the effect of inhaled mealtime insulin, increasing the likelihood of hypoglycemia. Sucrose absorption is delayed by miglitol, so table sugar will not reverse low glucose reliably.
What this interaction means in plain words
Insulin inhaled 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 lower the inhaled insulin dose if hypoglycemia develops. Treat episodes with glucose (dextrose), not sucrose.
What to ask your pharmacist
- Should I take them at different times of day?
- Does the dose of either medicine need to change?
- Is there anything I should avoid, such as alcohol or certain foods, while on both?
