Uses for Lescol XL
Fluvastatin is used together with a proper diet to lower high cholesterol and triglycerides (fats) in the blood. This medicine may help prevent medical problems, like atherosclerosis (hardening of the arteries), that are caused by fats clogging the blood vessels. It may also be used to prevent certain types of heart and blood vessel problems in patients with risk factors for heart problems.
Fluvastatin belongs to the group of medicines called HMG-CoA reductase inhibitors, or statins. It works by blocking an enzyme that is needed by the body to make cholesterol, which reduces the amount of cholesterol in the blood.
This medicine is available only with your doctor's prescription.
