Cardizem SR is primarily used to treat high blood pressure (hypertension), angina pectoris (chest pain), and certain types of heart rhythm disorders.

Use and Dosage

Your doctor may gradually increase your dose. Follow your doctor’s instructions carefully. The dosage is based on your medical condition, response to treatment, and other medications you may be taking.
