Drug Name

Lescol XL (fluvastatin)

Drug Uses

Fluvastatin is in a group of drugs called HMG CoA reductase inhibitors, or "statins." Fluvastatin 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).

Fluvastatin is used to treat high cholesterol in adults and children who are at least 10 years old. Lowering your cholesterol can help prevent heart disease and hardening of the arteries, conditions that can lead to heart attack, stroke, and vascular disease.

Fluvastatin may also be used for other purposes not listed in this medication guide.

Warnings/Precautions

You should not take fluvastatin if you are allergic to it, if you are pregnant or breast-feeding, or if you have liver disease.

If you have any of these other conditions, you may need a dose adjustment or special tests:

• history of liver disease;
• history of kidney disease;
• diabetes;
• a thyroid disorder; or
• if you drink more than 2 alcoholic beverages daily.

In rare cases, fluvastatin can cause a condition that results in the breakdown of skeletal muscle tissue, leading to kidney failure. This condition may be more likely to occur in older adults and in people who have kidney disease or poorly controlled hypothyroidism (underactive thyroid).

Tell your doctor about all other medications you use. Certain other drugs can increase your risk of serious muscle problems, and it is very important that your doctor knows if you are using any of them:

• erythromycin (E.E.S., EryPed, Ery-Tab, Erythrocin);
• fluconazole (Diflucan)
• gemfibrozil (Lopid), fenofibric acid (Fibricor, Trilipix), or fenofibrate (Antara, Fenoglide, Lipofen, Lofibra, Tricor, Triglide);
• medicines that contain niacin (Advicor, Niaspan, Niacor, Simcor, Slo-Niacin, and others); or
• drugs that weaken your immune system, such as steroids, cancer medicine, or medicines used to prevent organ transplant rejection, such as cyclosporine (Gengraf, Neoral, Sandimmune), sirolimus (Rapamune), or tacrolimus (Prograf).

Do not take fluvastatin if you are pregnant. Stop taking this medication and tell your doctor right away if you become pregnant. Use effective birth control to avoid pregnancy while you are taking fluvastatin. Fluvastatin may pass into breast milk and could harm a nursing baby. Do not breast-feed while you are taking fluvastatin.
