Diltiazem ER Oral 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 ER Oral
Take this medication by mouth before meals and at bedtime, usually 3 to 4 times daily or as directed by your doctor.
The dosage is based on your medical condition and response to treatment. 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).
