Summary
Oral calcium may reduce beta-blocker absorption in some cases, though data for nadolol are scarce. Intravenous calcium chloride is unlikely to affect nadolol absorption, but calcium can oppose the negative inotropic effects of beta-blockade.
What this interaction means in plain words
Calcium chloride 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
Possible reduced absorption with oral calcium; pharmacodynamic opposition to beta-blocker cardiac effects with IV calcium.
What to do
If calcium is given orally, separate dosing by about 2 hours; monitor heart rate and blood pressure.
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?
