Cardizem

Generic name: Diltiazem hydrochloride

Why is Cardizem prescribed?

Cardizem and Cardizem CD (a controlled release form of diltiazem) are used in the treatment of angina pectoris (chest pain usually caused by lack of oxygen to the heart due to clogged arteries). Cardizem, Cardizem CD, and Cardizem LA (an extended-release, once-a-day tablet form of diltiazem) are used to control chronic stable angina (caused by exertion). Cardizem CD and Cardizem LA are also used to treat high blood pressure. Another controlled release form, Cardizem SR, is used only in the treatment of high blood pressure. Cardizem, a calcium channel blocker, dilates blood vessels and slows the heart to reduce blood pressure and the pain of angina.

Doctors sometimes prescribe Cardizem for loss of circulation in the fingers and toes (Raynaud's phenomenon), for involuntary movements (tardive dyskinesia), and to prevent heart attack.

Tiazac and Dilacor XR are used in the treatment of high blood pressure and chronic stable angina. They may be taken alone or combined with other blood pressure medications.

Most important fact about Cardizem

If you are taking Cardizem for high blood pressure, remember that it does not cure the problem; it merely controls it. You may need to take a blood pressure medication for the rest of your life.

If you are taking Cardizem for angina, do not stop suddenly. This can lead to an increase in your attacks.

How should you take Cardizem?

Cardizem should be taken before meals and at bedtime. Cardizem CD, Cardizem LA, Cardizem SR, and Dilacor XR should be swallowed whole; do not chew, crush, or divide. Tiazac capsules may be swallowed whole or opened and sprinkled on a spoonful of applesauce. Swallow the applesauce immediately, without chewing, and wash it down with a glass of cool water.

Take this medication exactly as prescribed by your doctor, even if your symptoms have disappeared.
