Summary
Guanfacine, a central alpha-2 agonist, may blunt the adrenergic warning symptoms of hypoglycemia such as tremor and palpitations. Patients may therefore fail to recognize low blood glucose early, though sweating is typically preserved.
What this interaction means in plain words
Guanfacine and Insulin glulisine 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 glulisine belongs to Endocrine.
Why it happens
Reduced central sympathetic outflow dampens catecholamine-mediated hypoglycemia symptoms.
What to do
Counsel patients to rely on blood glucose measurements rather than symptoms and monitor glucose more often when guanfacine is started.
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?
