tell your doctor and pharmacist if you are allergic to lovastatin, any other medications, or any of the ingredients in lovastatin tablets or extended-release tablets. Ask your pharmacist for a list of the ingredients.
tell your doctor if you are taking any of the following medications: antifungals such as itraconazole (Sporanox), ketoconazole (Nizoral), posaconazole (Noxafil), and voriconazole (Vfend); boceprevir (Victrelis); clarithromycin (Biaxin); cobicistat-containing medications (Stribild); erythromycin (E.E.S.,EryC); nefazodone; certain HIV protease inhibitors including atazanavir (Reyataz), darunavir (Prezista), fosamprenavir (Lexiva), indinavir (Crixivan), lopinavir (in Kaletra), nelfinavir (Viracept), ritonavir (Norvir, in Kaletra), saquinavir (Invirase), and tipranavir (Aptivus); telaprevir (Incivek); and telithromycin (Ketek). Your doctor will probably tell you not to take lovastatin if you are taking one or more of these medications.
tell your doctor and pharmacist what prescription and nonprescription medications, vitamins, nutritional supplements, and herbal products you are taking or plan to take. Be sure to mention any of the following: amiodarone (Cordarone, Pacerone); anticoagulants ('blood thinners') such as warfarin (Coumadin); cimetidine (Tagamet); colchicine (Colcrys); cyclosporine (Neoral, Sandimmune); danazol (Danocrine); diltiazem (Cardizem, Dilacor, Tiazac); dronedarone (Multaq); other cholesterol-lowering medications such as fenofibrate (Tricor), gemfibrozil (Lopid), and niacin (nicotinic acid, Niacor, Niaspan); spironolactone (Aldactone); ranolazine (Ranexa); and verapamil (Calan, Covera, Isoptin, Verelan) . Many other medications may also interact with lovastatin, so be sure to tell your doctor about all the medications you are taking, even those that do not appear on this list. Your doctor may need to change the doses of your medications or monitor you carefully for side effects.
tell your doctor if you have liver disease. Your doctor will order laboratory tests to see how well your liver is working even if you do not think you have liver disease. Your doctor will probably tell you not to take lovastatin if you have liver disease or if the tests show that you may be developing liver disease.
tell your doctor if you drink more than two alcoholic beverages daily, if you are 65 years of age or older, if you have ever had liver disease or if you have or have ever had seizures, muscle aches or weakness, low blood pressure, diabetes, or kidney disease.
tell your doctor if you are pregnant or plan to become pregnant. You should not become pregnant while you are taking lovastatin. Talk to your doctor about birth control methods that you can use during your treatment. If you become pregnant while taking lovastatin, stop taking lovastatin and call your doctor immediately. Lovastatin may harm the fetus.
do not breastfeed while you are taking this medication.
if you are having surgery, including dental surgery, tell the doctor or dentist that you are taking lovastatin. If you are hospitalized due to serious injury or infection, tell the doctor who treats you that you are taking lovastatin.
ask your doctor about the safe use of alcoholic beverages while you are taking lovastatin. Alcohol can increase the risk of serious side effects.
