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 without prescriptions?
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 Cardizem exactly as prescribed by your doctor, even if your symptoms
have disappeared.
If you miss a dose Cardizem CD (Diltiazem)
If you forget to take a dose, take it as soon as you remember. If
it's almost time for your next dose, skip the missed dose and go back
to your regular schedule. Never take 2 doses at the same time.
Storage instructions...
Cardizem should be stored at room temperature; protect from moisture.

Why should Cardizem not be prescribed?
If you suffer from "sick sinus" syndrome or second- or third-degree

Do not take diltiazem if you have low blood pressure or an allergy
to the drug.
