Summary
Guanfacine is a central alpha-2 agonist that lowers sympathetic outflow and may blunt adrenergic warning symptoms of hypoglycemia such as tremor and palpitations. Patients may therefore fail to recognize falling glucose early. The effect is generally modest.
What this interaction means in plain words
Guanfacine and Insulin glargine-lixisenatide 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; Insulin glargine-lixisenatide belongs to Endocrine.
Why it happens
Reduced sympathetic activity dampens catecholamine-mediated autonomic warning symptoms of hypoglycemia.
What to do
Advise patients that hypoglycemia may present with fewer adrenergic symptoms and encourage regular blood glucose self-monitoring. Sweating is usually preserved and can be used as a cue.
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?
