Summary
Calcium can in theory oppose the effect of calcium channel blockers. Oral calcium supplements at usual doses rarely reduce the antihypertensive effect, but intravenous calcium or hypercalcemia may do so.
What this interaction means in plain words
Calcium carbonate and Nicardipine have a small, usually unimportant interaction. Most people can take both; the pharmacist may still mention it so that any unexpected effect is recognised.
Calcium carbonate belongs to Gastrointestinal Tract; Nicardipine belongs to Cardiovascular.
Why it happens
Pharmacodynamic antagonism: raised extracellular calcium may counteract calcium channel blockade.
What to do
No routine change is needed with oral calcium at usual doses. Monitor blood pressure and serum calcium if high-dose calcium or vitamin D is used.
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?
