Notice
[Posted 3/1/2012] ISSUE: FDA notified healthcare professionals of updates to the prescribing information concerning interactions between protease inhibitors and certain statin drugs. Protease inhibitors and statins taken together may raise the blood levels of statins and increase the risk for muscle injury (myopathy). The most serious form of myopathy, called rhabdomyolysis, can damage the kidneys and lead to kidney failure, which can be fatal.
BACKGROUND: Statins are a class of prescription drugs used together with diet and exercise to reduce blood levels of low-density lipoprotein (LDL) cholesterol (''bad cholesterol''). HIV protease inhibitors are a class of prescription anti-viral drugs used to treat HIV. HCV protease inhibitors are a class of prescription anti-viral drugs used to treat hepatitis C infection.
RECOMMENDATION: Healthcare professionals should follow the recommendations in the prescribing information (drug labels) when prescribing HIV or HCV protease inhibitors with statins. See the FDA Drug Safety Communication for additional information, including a data summary. For more information visit the FDA website at: http://www.fda.gov/Safety/MedWatch/SafetyInformation and http://www.fda.gov/Drugs/DrugSafety.
[Posted 2/28/2012] ISSUE: FDA has approved important safety label changes for the class of cholesterol-lowering drugs known as statins. The changes include removal of routine monitoring of liver enzymes from drug labels. Information about the potential for generally non-serious and reversible cognitive side effects and reports of increased blood sugar and glycosylated hemoglobin (HbA1c) levels has been added to the statin labels.
The lovastatin (Mevacor) label has been extensively updated with new contraindications and dose limitations when it is taken with certain medicines that can increase the risk for muscle injury.
Read the FDA Drug Safety Communication for more information at: http://www.fda.gov/Drugs/DrugSafety/ucm293101.htm
BACKGROUND: Statins are a class of prescription drugs used together with diet and exercise to reduce blood levels of low-density lipoprotein (LDL) cholesterol (''bad cholesterol''). Marketed as single-ingredient products, including atorvastatin (Lipitor), fluvastatin (Lescol), lovastatin (Mevacor), lovastatin extended-release (Altoprev), pitavastatin (Livalo), pravastatin (Pravachol), rosuvastatin (Crestor), and simvastatin (Zocor). Also marketed as combination products, including lovastatin/niacin extended-release (Advicor), simvastatin/niacin extended-release (Simcor),and simvastatin/ezetimibe (Vytorin).
RECOMMENDATION: Healthcare professionals should perform liver enzyme tests before initiating statin therapy in patients and as clinically indicated thereafter. If serious liver injury with clinical symptoms and/or hyperbilirubinemia or jaundice occurs during treatment, therapy should be interrupted. If an alternate etiology is not found, the statin should not be restarted.
Healthcare professionals should follow the recommendations in the lovastatin label regarding drugs that may increase the risk of myopathy/rhabdomyolysis when used with lovastatin. For more information visit the FDA website at: http://www.fda.gov/Safety/MedWatch/SafetyInformation and http://www.fda.gov/Drugs/DrugSafety.
Why is this medication prescribed?
Lovastatin is used together with lifestyle changes (diet, weight-loss, exercise) to reduce the amount of cholesterol (a fat-like substance) and other fatty substances in the blood. Lovastatin is in a class of medications called HMG-CoA reductase inhibitors (statins). It works by slowing the production of cholesterol in the body.
Buildup of cholesterol and fats along the walls of the blood vessels (a process known as atherosclerosis) decreases blood flow and, therefore, the oxygen supply to the heart, brain, and other parts of the body. Lowering blood levels of cholesterol and fats may help to decrease your risk of heart disease, angina (chest pain), strokes, and heart attacks. In addition to taking a cholesterol-lowering medication, making certain changes in your daily habits can also lower your cholesterol blood levels. You should eat a diet that is low in saturated fat and cholesterol (see SPECIAL DIETARY), exercise 30 minutes on most, if not all days, and lose weight if you are overweight.
How should this medicine be used?
Lovastatin comes as a tablet and an extended-release (long-acting) tablet to take by mouth. The regular tablet usually is taken once or twice a day with meals. The extended-release tablet usually is taken once a day in the evening at bedtime. Take lovastatin at around the same time(s) every day. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take lovastatin exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.
Swallow the extended-release tablets whole; do not split, chew, or crush them.
Your doctor may start you on a low dose of lovastatin and gradually increase your dose, not more than once every 4 weeks.
Continue to take lovastatin even if you feel well. Do not stop taking lovastatin without talking to your doctor.
Other uses for this medicine
This medication may be prescribed for other uses; ask your doctor or pharmacist for more information.
What special precautions should I follow?
Before taking lovastatin,
tell your doctor and pharmacist if you are allergic to lovastatin or any other medications.

Be sure to mention any of the following: amiodarone (Cordarone, Pacerone); anticoagulants ('blood thinners') such as warfarin (Coumadin); antifungal medications such as itraconazole (Sporanox) and ketoconazole (Nizoral); cimetidine (Tagamet); clarithromycin (Biaxin); cyclosporine (Neoral, Sandimmune); danazol (Danocrine); erythromycin (E.E.S., E-Mycin, Erythrocin); HIV protease inhibitors such as indinavir (Crixivan), ritonavir (Norvir) and saquinavir (Fortovase, Invirase); nefazodone (Serzone); other cholesterol-lowering medications such as fenofibrate (Tricor), gemfibrozil (Lopid), and niacin (nicotinic acid, Niacor, Niaspan); spironolactone (Aldactone); telithromycin (Ketek); and verapamil (Calan, Covera, Isoptin, Verelan). Your doctor may need to change the doses of your medications or monitor you carefully for side effects.

tell your doctor if you drink large amounts of alcohol, if you have ever had liver disease or if you have or have ever had kidney disease.
