Consumer:Ask your doctor before using erythromycin together with fluvastatin. Using these medications together can increase your blood levels of fluvastatin and may cause a dangerous side effect on your muscles. If your doctor prescribes these medications together, you may need a dose adjustment or special tests to safely take both medications. You should also watch for muscle symptoms and call the doctor if you have muscle pain, tenderness, or weakness, especially if you also have dark colored urine. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.
Professional:GENERALLY AVOID: Severe myopathy and rhabdomyolysis have been reported with concomitant use of HMG-CoA reductase inhibitors and erythromycin in severely ill patients. The suspected mechanism is inhibition of HMG-CoA reductase inhibitor metabolism by CYP450 3A4 isoenzymes.
MANAGEMENT: While these effects have not been reported with concomitant use of fluvastatin and erythromycin, alternative therapy should be considered. If patients do receive this combination, they should be instructed to report symptoms of muscular pain, weakness, tenderness, malaise, or fever. If such symptoms occur, creatine kinase should be measured. Fluvastatin and erythromycin should be discontinued if creatine kinase is elevated.
