Brand name:

Mevacor

Generic name: Lovastatin

Why is Mevacor prescribed?

Mevacor is used, along with diet, to lower cholesterol levels in people with primary hypercholesterolemia (too much cholesterol in the bloodstream). High cholesterol levels foster the buildup of artery-clogging plaque, which can be especially dangerous when it collects in the vessels serving the muscles of the heart. Mevacor is prescribed to prevent this problem—called coronary heart disease—or to slow its advance if the arteries are already clogging up.

Most important fact about Mevacor

Mevacor is usually prescribed only if diet, exercise, and weight-loss fail to bring your cholesterol levels under control. It's important to remember that Mevacor is a supplement—not a substitute—for these other measures. To get the full benefit of the medication, you need to stick to the diet and exercise program prescribed by your doctor.

Mevacor should be taken with meals.

Special warnings about Mevacor

If you are being treated for any disease that contributes to increased blood cholesterol, such as hypothyroidism, diabetes, nephrotic syndrome (kidney and blood vessel disorder), dysproteinemia (an excess of protein in the blood), or liver disease, your doctor will closely monitor your reaction to Mevacor.

Drugs like Mevacor have occasionally been known to damage muscle tissue, so be sure to tell your doctor immediately if you notice any unexplained muscle tenderness, weakness, or pain, especially if you also have a fever or feel sick. Your doctor may want to do a blood test to check for signs of muscle damage.

It is recommended that liver function tests be performed by your doctor before treatment with Mevacor begins, at 6 and 12 weeks after your treatment has started or your dosage has been raised, and periodically (about 6-month intervals) thereafter.

If you are planning to have elective surgery, Mevacor should be discontinued a few days before the operation. This drug should be used with caution if you consume substantial quantities of alcohol or have a past history of liver disease.

Fenofibrate

Fluconazole

Gemfibrozil

Itraconazole
