Fluvastatin is used together with diet to lower blood levels of "bad" cholesterol (low-density lipoprotein, or LDL), to increase levels of "good" cholesterol (high-density lipoprotein, or HDL), and to lower triglycerides (a type of fat in the blood). Fluvastatin is used to slow the build-up of plaque (fatty deposits) in your blood vessels. Fluvastatin is also used to lower the risk of heart complications in certain people with coronary heart disease.
