Summary
Glucagon raises blood glucose and therefore opposes the glucose-lowering effect of metformin, though this is typically brief when glucagon is used for hypoglycemia. Metformin alone rarely causes hypoglycemia, so the combination is seldom relevant.
What this interaction means in plain words
Glucagon and Metformin have a small, usually unimportant interaction. Most people can take both; the pharmacist may still mention it so that any unexpected effect is recognised.
Glucagon belongs to Endocrine; Metformin belongs to Endocrine.
Why it happens
Pharmacodynamic antagonism: glucagon stimulates hepatic glucose production.
What to do
Monitor blood glucose after glucagon administration and adjust antidiabetic therapy if hyperglycemia persists.
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?
