Who should take a calcium channel blocker for treatment of CAD?

Donna Hill Howes, RN
Family Practitioner

Calcium channel blockers are often prescribed for people with coronary artery disease who cannot take a beta blocker because of pre-existing conditions or intolerable side effects. Calcium channel blockers are also sometimes prescribed for people who have symptoms of angina while taking a beta blocker. However, the combination of a beta blocker and a calcium channel blocker can cause extreme fatigue and carries a risk of slow heart rate or AV block.
