Use caution in patients with history of gastrointestinal disease

Clostridium difficile associated diarrhea (CDAD) reported with use of nearly all antibacterial agents, and may range in severity from mild diarrhea to fatal colitis; if CDAD is suspected or confirmed, discontinue ongoing antibacterial drug use not directed against C. difficile; institute appropriate fluid and electrolyte management, protein supplementation, antibacterial drug treatment of C. difficile, and surgical evaluation as clinically indicated

Immune-mediated hemolytic anemia reported; monitor hematologic parameters during and for 2 to 3 weeks after therapy; discontinue therapy if hemolytic anemia occurs during treatment

Cephalosporins may be associated with a fall in prothrombin activity; patients with renal or hepatic impairment, or poor nutritional state, patients receiving a protracted course of antimicrobial therapy, and patients previously stabilized on anticoagulant therapy; monitor prothrombin time in patients at risk and exogenous vitamin K administered as indicated

May cause acute renal failure including tubulointerstitial nephritis; discontinue therapy if renal failure occurs and initiate supportive therapy
