Summary
Calcium may theoretically oppose the vasodilating action of calcium channel blockers. Oral calcium at usual doses rarely matters, but hypercalcemia could reduce blood pressure control.
What this interaction means in plain words
Calcium carbonate and Isradipine 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
Pharmacodynamic antagonism, as raised extracellular calcium may counter calcium channel blockade; largely theoretical.
What to do
No routine change is required. Check blood pressure response and serum calcium if high doses of calcium are 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?
