Taking Calcium Channel Blockers such as NIFEDIPINE together with calcium containing supplements is a DEATH TRAP
Here’s why:
You should not take large amounts of calcium supplements with nifedipine because calcium supplements can decrease the effectiveness of the nifedipine, a calcium channel blocker.
Nifedipine works by blocking calcium from entering muscle cells to help them relax, but taking extra calcium can counteract this effect.
Supplemental calcium can decrease the effect of nifedipine by introducing more calcium into the body, making the drug less effective at relaxing the blood vessels.
This interaction could make your nifedipine less effective at controlling your blood pressure. You may need a dose adjustment or more frequent blood pressure checks.
If you are taking nifedipine, talk to your doctor before taking calcium supplements. They can advise you on the appropriate dose and monitor your blood pressure and calcium levels.
