DRUG INTERACTIONS: See also the How To Use section. This drug should not be used with the following medications because very serious, possibly fatal interactions may occur: certain azole antifungals (e.g., itraconazole, ketoconazole), delavirdine, HIV protease inhibitors (e.g., ritonavir, amprenavir, lopinavir), certain macrolide antibiotics (e.g., erythromycin, clarithromycin, troleandomycin), mibefradil, nefazodone, telithromycin. If you are currently using any of these medications, tell your doctor or pharmacist before starting lovastatin. Use caution if the following drugs are combined with lovastatin because serious side effects such as muscle injury (myopathy) infrequently could occur: fibrates (e.g., gemfibrozil, fenofibrate), high-dose niacin (1 gram or more per day). Before using this medication, tell your doctor or pharmacist of all prescription and nonprescription/herbal products you may use, especially of: azithromycin, "blood thinners" (e.g., warfarin), cholestyramine, colestipol, other drugs which affect certain liver enzymes (CYP 3A4 substrates, inhibitors, and inducers such as amiodarone, cyclosporine, diltiazem, verapamil, rifampin, St. John's wort, carbamazepine). Do not start or stop any medicine without doctor or pharmacist approval.
