Summary
Guanfacine is a centrally acting alpha-2 agonist that may blunt the adrenergic warning symptoms of hypoglycemia such as tremor and palpitations. Saxagliptin rarely causes hypoglycemia alone, so the concern mainly applies when insulin or sulfonylureas are also used.
What this interaction means in plain words
Guanfacine and Saxagliptin 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; Saxagliptin belongs to Endocrine.
Why it happens
Reduced sympathetic outflow from central alpha-2 agonism may mask catecholamine-mediated hypoglycemia symptoms.
What to do
Teach patients that hypoglycemia symptoms may be less obvious and encourage regular blood glucose monitoring, particularly if insulin or a sulfonylurea is co-prescribed.
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?
