Cardizem (Diltiazem) is used to prevent chest pain (angina). This means it helps reduce the frequency and severity of angina attacks, not relieve them once they occur.

It may improve your exercise tolerance and decrease angina episodes. This can potentially enhance your daily activities and quality of life.

Diltiazem belongs to a class of medications called calcium channel blockers. It works by:

  • Relaxing blood vessels in your body and heart, allowing it to pump blood more efficiently.
  • Lowering your heart rate, reducing the workload on your heart.


  • Take Cardizem by mouth as directed by your doctor, usually 3-4 times a day, before meals and at bedtime.Avoid crushing, chewing, or breaking the tablets.
  • The dose depends on your specific health condition, response to the medication, and other medications you might be taking. Inform your doctor and pharmacist about all your medications, including prescription, non-prescription, and herbal products.
  • Take Cardizem regularly at the same times each day for maximum benefit. Your doctor might gradually increase your dosage for optimal effect.
  • Cardizem is used to prevent angina attacks, not to treat them when they occur. Use other medications prescribed by your doctor for angina attacks, like sublingual nitroglycerin.

Cardizem can cause dizziness, so avoid driving, operating machinery, or activities requiring alertness until you feel safe doing so. Limit alcohol and marijuana use as they can worsen dizziness.
