Interactions between macrodantin(nitrofurantoin) and Cellcept (mycophenolate mofetil)
nitrofurantoin and mycophenolate mofetil (Moderate Drug-Drug)
MONITOR: Theoretically, drugs that alter the gastrointestinal flora (e.g., antibiotics) may reduce the oral bioavailability of mycophenolic acid products. Some investigators believe that antimicrobials may interfere with the enterohepatic recirculation of mycophenolic acid by decreasing bacterial hydrolytic enzymes in the gastrointestinal tract that are responsible for regenerating mycophenolic acid from its glucuronide metabolite following first-pass metabolism.
MANAGEMENT: Close clinical and laboratory monitoring for evidence of diminished immunosuppressive effect of mycophenolic acid is recommended during concomitant therapy with anti-infective agents.
