What is the most important information I should know about ranolazine (Ranexa)?

You should not take ranolazine if you have cirrhosis of the liver. There are many other drugs that should not be used together with ranolazine. Tell your doctor about all other medicines you use.

Ranolazine is not for use during an acute (emergency) attack of angina. Continue using any other medicines prescribed by your doctor (such as nitroglycerin) to treat acute angina.

Before you take ranolazine, tell your doctor about all of your medical conditions, especially if you have a personal or family history of Long QT syndrome.

Do not crush, chew, or break an extended-release tablet. Swallow it whole. Breaking the pill may cause too much of the drug to be released at one time.

Chronic angina is often treated with a combination of different drugs. To best treat your condition, use all of your medications as directed by your doctor. Do not change your doses or medication schedule without advice from your doctor.
