    Expert advice for Diltiazem

    • Diltiazem slows down the heartbeat and allows the blood vessels in the body to relax.
    • This helps prevent angina attacks (chest pain caused by heart disease), certain abnormal heart rhythms, stroke and heart attack.
    • It may cause dizziness or sleepiness. Do not drive or do anything requiring concentration until you know how it affects you.
    • It may cause you to feel lightheaded or weak especially when you stand up (orthostatic hypotension). Rise slowly if you have been sitting or lying down. 
    • It is best to avoid drinking alcohol while taking Diltiazem as it may make the side effects worse.
    • Do not stop taking it suddenly without talking to your doctor first.
