Summary
Glucagon can transiently raise heart rate and blood pressure, and this effect may be greater in patients on beta-blockers. Beta-blockers can also blunt the counter-regulatory response and mask hypoglycemia symptoms. Glucagon's hyperglycemic effect is not reduced, so it remains effective for severe hypoglycemia.
What this interaction means in plain words
Carvedilol and Glucagon intranasal have a small, usually unimportant interaction. Most people can take both; the pharmacist may still mention it so that any unexpected effect is recognised.
Why it happens
Glucagon-induced catecholamine release produces unopposed alpha-adrenergic vasoconstriction in patients taking beta-blockers.
What to do
Use glucagon as needed for severe hypoglycemia. Monitor blood pressure and pulse afterward, and check glucose until recovery is sustained.

- Is there anything I should notice while taking both?
- Do I need to tell my doctor at the next visit?
