Calcium Channel Blockers (CCBs) are used by millions of Americans to treat high blood pressure, angina, and certain heart rhythm abnormalities. The monthly cost for these drugs varies from less than $20 to more than $200. This report gives you information that will help you: (a) determine when you might need a CCB; (b) choose the right CCB and dosage; and (c) save $1,000 to $1,700 a year if you are currently taking or have been prescribed an expensive brand-name CCB.

CCBs are effective medicines that have been shown to lower blood pressure and help prevent and treat the symptoms of angina (chest pain). In addition, two CCBs are effective in controlling certain heart rhythm problems.

CCBs are typically not prescribed as initial or first-line treatment in people with high blood pressure who have no other form of heart disease. Instead, CCBs are often used as a second or third drug to help lower blood pressure when other drugs have failed to bring levels down enough.

CCBs should be considered as initial treatment (usually in combination with other drugs) for people who have high blood pressure plus angina and/or a high risk of stroke. CCBs should not be taken by people with heart failure (often called congestive heart failure).

• As a second drug for high blood pressure – amlodipine
• For angina – amlodipine
• For heart rhythm abnormalities – diltiazem CD, diltiazem SR, and verapamil SR
