For healthcare professionals — reference only. This page is a brief summary, not medical advice and not a substitute for official labeling or clinical judgement. Always verify before prescribing or dispensing.
Summary
Glucagon increases heart rate and contractility independently of beta receptors, so it can reverse beta-blocker toxicity. In patients on betaxolol, glucagon is used as an antidote for severe bradycardia or hypotension. Its use outside of that context causes only transient hemodynamic changes.
What this interaction means in plain words
Betaxolol and Glucagon have a small, usually unimportant interaction. Most people can take both; the pharmacist may still mention it so that any unexpected effect is recognised.
Betaxolol belongs to Cardiovascular; Glucagon belongs to Endocrine.
Why it happens
Glucagon stimulates glucagon receptors and raises cAMP via a pathway that bypasses blocked beta receptors.
What to do
No action is needed for routine use. Monitor heart rate, blood pressure and glucose when glucagon is used to treat beta-blocker overdose.
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?
