Lescol XL

Brand Name: Lescol XL

Generic Name: Fluvastatin

Drug Class: Lipid-Lowering Agents, Statins; HMG-CoA Reductase Inhibitors

What Is Lescol XL and How Does It Work?

Lescol XL (fluvastatin) is approved by the FDA as a prescription drug used to treat high cholesterol in the blood. Lescol XL belongs to a class of medications called statins. Statin drugs are lipid-lowering drugs that have been found to reduce cardiovascular disease (such as stroke) and coronary heart disease (such as heart attack) in high-risk patients.

Fluvastatin works by blocking the enzyme in the liver that is responsible for making cholesterol. The enzyme is called hydroxy-methylglutaryl-coenzyme A reductase (HMG-CoA reductase). Since statins like fluvastatin prevent the production of this enyme, fluvastatin is also referred to as an HMG-CoA reductase inhibitor.

Fluvastatin is also available under different brand names including Lescol and Lescol XL, and are available as 20 mg capsules, 40 mg capsules and 80 mg extended-release tablets. Other examples of statins that are approved for use in the U.S. include atorvastatin (Lipitor), fluvastatin (Lescol, Lescol XL), lovastatin (Mevacor, Altoprev), pravastatin (Pravachol), rosuvastatin (Crestor), simvastatin (Zocor), and pitavastatin (Livalo).

Dosages of Lescol XL Should Be Given As Follows:

  • Patients start fluvastatin at 20 mg - 40 mg, taken orally every night at bedtime.
  • Dosing ranges from 20 mg - 80 mg, taken orally every day.
  • For patients requiring 80mg per day, doses should be divided into two 40 mg doses taken orally, every 12 hours.
  • Sustained-release doses are taken at the full 80 mg, taken orally every day.
  • Dosage Considerations

    Some patients requiring a reduction of 25% or less of low density lipoprotein cholesterol (LDL C) may have their doses adjusted from the standard dose of 20 mg taken orally every day.

    Based on response and tolerance to therapy, these patients should not exceed 40 mg taken orally, every 12 hours (with immediate release capsules). These patients should not exceed 80 mg (extended-release tablets) per 24-hour period.

    Patients with mild renal impairment should not exceed 40 mg per day.

    Fluvastatin should not be taken by patients with active liver disease, or by patients with unexplained elevated liver enzymes.

    Overdose

    Overdose from fluvastatin may cause adverse reactions including nerve pain, diarrhea, elevated levels of potassium in the blood, muscle pain, muscle breakdown, kidney failure, elevated liver enzymes, and clouding of the lens of the eyes.
