Summary
Miglitol adds to the glucose-lowering effect of NPH insulin, so hypoglycemia can occur more readily. Delayed sucrose absorption makes table sugar unreliable for correcting low glucose.
What this interaction means in plain words
Insulin nph 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 adjust the NPH dose when miglitol is started or stopped. Use glucose (dextrose) to treat hypoglycemia.
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?
