Doctors prescribe calcium channel blockers to prevent, treat or improve symptoms in a variety of conditions, such as:
Calcium channel blockers may not be as effective as diuretics, beta blockers or angiotensin-converting enzyme (ACE) inhibitors at lowering blood pressure. Because of this, calcium channel blockers aren't usually the first medication you'd be prescribed to lower your blood pressure.
However, for blacks, calcium channel blockers may be more effective than other blood pressure medications, such as beta blockers, ACE inhibitors or angiotensin II receptor blockers.
Side effects of calcium channel blockers may include:
Certain calcium channel blockers interact with grapefruit products. Check with your pharmacist or physician before taking a calcium channel blocker. Some calcium channel blockers can reduce your ability to eliminate calcium channel blockers from your body, allowing the medication to build up in your body. This buildup could cause serious side effects.
