Zocor (SIMVASTATIN) is an HMG-CoA reductase inhibitor or 'statin' used to lower bad cholesterol (LDL) and triglyceride levels in your blood or to raise good cholesterol (HDL) levels in adults. This medicine is used in combination with a low-cholesterol and low-fat diet. Simvastatin may also be used in certain adolescent patients, age 10 to 17 years, who have a genetically caused cholesterol problem. This medicine works by blocking an enzyme that is necessary for your body to make cholesterol. When this enzyme is blocked, your body makes less cholesterol. Keeping your cholesterol level under control may reduce your risk of heart problems and stroke. This medicine is not a cure for high cholesterol, but may help to control it. This medicine may also be used to treat other conditions as determined by your doctor.
