Simvastatin blocks the production of cholesterol (a type of fat) in the body.

Simvastatin is used to reduce the total amounts of cholesterol, LDL (bad) cholesterol, triglycerides (another type of fat), and apolipoprotein B (a protein needed to make cholesterol) in your blood. Simvastatin (Zocor) is also used to increase the level of HDL (good) cholesterol in your blood. These actions may reduce the risk of hardening of the arteries, which can lead to heart attacks, stroke, and peripheral vascular disease.

Simvastatin may also be used for purposes other than those listed in this medication guide.
