Question: what are the side effects of taking calcium channel blocker?
Answer: The most common side effects of the dihydropyridine CCBs are ankle swelling, flushing and palpitations. The non-dihyropyridines, especially verapamil, can cause constipation and may slow your heart rate. Both classes of CCBs may also cause your blood pressure to drop excessively, which can result in dizziness.
