Who should avoid taking calcium-channel blockers?
- Rate-limiting calcium-channel blockers (verapamil and diltiazem) are contraindicated in people with:
- Heart failure.
- Bradycardia or atrioventricular block.
- Cardiac outflow obstruction (significant aortic stenosis or obstructive hypertrophic cardiomyopathy): vasodilatation may result in reduced cardiac output.
- Dihydropyridine calcium-channel blockers should not be started in people with uncontrolled heart failure (but amlodipine and felodipine can be used if heart failure is stable).
