Summary
Glucagon can transiently increase heart rate and blood pressure, and patients on beta blockers may show a more marked rise in blood pressure from unopposed alpha effects. Beta blockers can also mask adrenergic hypoglycemia symptoms. The effect is typically short-lived.
What this interaction means in plain words
Glucagon intranasal and Nadolol 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 with nonselective beta blockade causing unopposed alpha stimulation.
What to do
Monitor blood pressure and pulse after glucagon administration. Confirm glucose recovery with blood glucose measurement rather than symptoms.
