Blood Pressure Home > Calcium Channel Blockers
Calcium channel blockers are prescribed medications used to treat various conditions of the heart and blood vessels. Specifically, they can treat high blood pressure, certain irregular heart rhythms, and chest pain. The medications help to slow down the rate of calcium movement to the heart and blood vessel walls, which relaxes the vessels and improves blood flow. Potential side effects include swelling, fatigue, and headaches.
