PRESCRIBED FOR: Diltiazem is used for treating heart pain (angina), high blood pressure, and abnormal heart rhythms such as atrial fibrillation, atrial flutter and paroxysmal supraventricular tachycardia.

SIDE EFFECTS: Side effects include:

Liver dysfunction and overgrowth of the gums also may occur. Diltiazem can cause mildly abnormal liver tests that usually return to normal with discontinuation of the medication. When diltiazem is given to individuals with heart failure, symptoms of heart failure may worsen because these drugs reduce the ability of the heart to pump blood. Like other drugs for high blood pressure, diltiazem is associated with sexual dysfunction.
