General Info:

Cardizem (Diltiazem) is in a class of drugs called calcium channel blockers. Cardizem (Diltiazem) relaxes (widens) your blood vessels (veins and arteries), which makes it easier for your heart to pump and reduces the workload on it. Cardizem (Diltiazem) is used to treat hypertension (high blood pressure), to treat angina (chest pain), and to slow unusually fast heartbeats.

Use caution when driving, operating machinery, or performing other hazardous activities. Cardizem (Diltiazem) may cause dizziness or drowsiness. If you experience dizziness or drowsiness, avoid these activities.

Do not stop taking Cardizem (Diltiazem) without first talking to your doctor. If you stop taking your medication, your condition could become worse.
