This drug is used to lower high cholesterol and/or triglyceride levels in the blood. High levels of cholesterol or triglycerides may block the blood vessels, increasing the risk of heart disease. For best results, this medication must be used along with an exercise program and a low-cholesterol, low-fat diet.

This drug is used to help prevent heart attacks, strokes and other problems caused by narrowed blood vessels ("hardening of the arteries").

Atorvastatin is an enzyme blocker (HMG-CoA reductase inhibitor), also known as a "statin". It is used along with a proper diet to help lower cholesterol and fats (triglycerides) in the blood. In general, this drug is prescribed after non-drug treatment options have not been fully successful at lowering cholesterol (e.g., diet change, increase in exercise, weight loss if overweight). Reducing cholesterol and triglycerides help prevent strokes and heart attacks. Atorvastatin is used in adults and children (10 years of age and older). Young girls must have had their first menstrual period before starting this medication.
