Mevacor is used for lowering high cholesterol in certain patients. It is used along with an appropriate diet. It is used in certain patients to reduce the risk of heart attack and chest pain caused by angina. It is also used to slow blood vessel blockage and to reduce the need for medical procedures to open blocked heart blood vessels. Mevacor is an HMG-CoA reductase inhibitor, also known as a “statin.” It works by reducing the production of certain fatty substances in the body, including cholesterol.
