Summary
Guanfacine, a central alpha-2 agonist, may blunt some adrenergic warning symptoms of hypoglycemia. With miglitol alone hypoglycemia is uncommon, but it matters if other antidiabetic drugs are used.
What this interaction means in plain words
Guanfacine and Miglitol have a small, usually unimportant interaction. Most people can take both; the pharmacist may still mention it so that any unexpected effect is recognised.
Guanfacine belongs to Cardiovascular; Miglitol belongs to Endocrine.
Why it happens
Central sympatholytic action reduces catecholamine-mediated hypoglycemia symptoms.
What to do
Advise patients to monitor blood glucose rather than rely on symptoms, particularly if combined with insulin or sulfonylureas.
What to ask your pharmacist
- Is there anything I should notice while taking both?
- Do I need to tell my doctor at the next visit?
