Dosage form: tablet

The information at Drugs.com is not a substitute for medical advice. ALWAYS consult your doctor or pharmacist.

The patient should be placed on a standard cholesterol-lowering diet before receiving MEVACOR and should continue on this diet during treatment with MEVACOR (see NCEP Treatment Guidelines for details on dietary therapy). MEVACOR should be given with meals.

Adult Patients

The usual recommended starting dose is 20 mg once a day given with the evening meal. The recommended dosing range of lovastatin is 10-80 mg/day in single or two divided doses; the maximum recommended dose is 80 mg/day. Doses should be individualized according to the recommended goal of therapy (see NCEP Guidelines and CLINICAL PHARMACOLOGY). Patients requiring reductions in LDL‑C of 20% or more to achieve their goal (see INDICATIONS AND USAGE) should be started on 20 mg/day of MEVACOR. A starting dose of 10 mg of lovastatin may be considered for patients requiring smaller reductions. Adjustments should be made at intervals of 4 weeks or more. The 10 mg dosage is provided for information purposes only. Although lovastatin tablets 10 mg are available in the marketplace, MEVACOR is no longer marketed in the 10 mg strength.

Cholesterol levels should be monitored periodically and consideration should be given to reducing the dosage of MEVACOR if cholesterol levels fall significantly below the targeted range.

Dosage in Patients taking Danazol, Diltiazem, Dronedarone or Verapamil

In patients taking danazol, diltiazem, dronedarone or verapamil concomitantly with lovastatin, therapy should begin with 10 mg of lovastatin and should not exceed 20 mg/day (see CLINICAL PHARMACOLOGY, Pharmacokinetics, WARNINGS, Myopathy/Rhabdomyolysis, PRECAUTIONS, Drug Interactions, Other Drug Interactions).
