What is Lescol XL?

Lescol XL is in a group of drugs called HMG CoA reductase inhibitors, or "statins." This medicine 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).

Lescol XL is used to lower cholesterol and triglycerides (types of fat) in the blood and to slow the build-up of plaque (fatty deposits) in your blood vessels.

Lescol XL is also used to lower the risk of heart complications in certain people with coronary heart disease.

Lescol XL is used in adults and children who are at least 10 years old.

Lescol XL may also be used for purposes not listed in this medication guide.
