Zocor (simvastatin) belongs to a group of drugs called HMG CoA reductase inhibitors, or "statins." Simvastatin reduces levels of "bad" cholesterol (low-density lipoprotein, or LDL) and triglycerides in the blood, while increasing levels of "good" cholesterol (high-density lipoprotein, or HDL).
Zocor is used to lower cholesterol and triglycerides (types of fat) in the blood.
It is also used to lower the risk of stroke, heart attack, and other heart complications in people with diabetes, coronary heart disease, or other risk factors.
Zocor is used in adults and children who are at least 10 years old.
Zocor may also be used for purposes not listed in this medication guide.
