Uses

Diltiazem is used to prevent chest pain (angina). It may help to increase your ability to exercise and decrease how often you may get angina attacks. Diltiazem is called a calcium channel blocker. It works by relaxing blood vessels in the body and heart and lowers the heart rate. Blood can flow more easily and your heart works less hard to pump blood.

How to use diltiazem oral

Take this medication by mouth before meals and at bedtime as directed by your doctor, usually 3 to 4 times a day. Swallow the tablets whole. Do not split, crush, or chew the tablets. Doing so can release all of the drug at once, increasing the risk of side effects. Follow your doctor's directions on how to take this medication.

The dosage is based on your medical condition, response to treatment, and other medications you may be taking. Be sure to tell your doctor and pharmacist about all the products you use (including prescription drugs, nonprescription drugs, and herbal products). Your doctor may gradually increase your dose. Follow your doctor's instructions carefully.

Use this medication regularly to get the most benefit from it. To help you remember, use it at the same times each day. This medication must be taken regularly to prevent angina. It should not be used to treat angina when it occurs. Use other medications (such as sublingual nitroglycerin) to relieve an angina attack as directed by your doctor. Consult your doctor or pharmacist for details.

Tell your doctor if your condition worsens (for example, your chest pain worsens or is more frequent).
