Hepatic: hepatic dysfunction
Skin: toxic epidermal necrolysis, diaper rash, erythema multiforme, Stevens-Johnson syndrome
Other: allergic reactions, carnitine deficiency, drug fever, superinfection, serum sickness-like reaction, anaphylaxis
Drug-drug.Aminoglycosides: increased risk of nephrotoxicity
Antacids containing aluminum or magnesium, histamine2-receptor antagonists: increased cefprozil absorption
Probenecid: decreased excretion and increased blood level of cefprozil
Drug-diagnostic tests.Alanine aminotransferase, alkaline phosphatase, aspartate aminotransferase, bilirubin, blood urea nitrogen, creatinine, eosinophils, gamma-glutamyltransferase, lactate dehydrogenase, white blood cells in urine: increased levels
Blood glucose, Coombs' test, urine glucose tests using Benedict's solution: false-positive results
Platelets, white blood cells: decreased counts

Stay alert for life-threatening reactions, including anaphylaxis, serum sickness-like reaction, Stevens-Johnson syndrome, and pseudomembranous colitis.
• Monitor neurologic status, particularly for signs and symptoms of impending seizures.
• Monitor kidney and liver function test results and assess fluid intake and output.
• Monitor CBC with white cell differential, prothrombin time, and bleeding time. Watch for signs and symptoms of blood dyscrasias, especially hypoprothrombinemia.
• Monitor temperature. Stay alert for signs and symptoms of superinfection.
Advise patient to immediately report rash, bleeding tendency, or CNS changes.
• Teach patient to recognize signs and symptoms of superinfection, and instruct him to report these right away.
• Tell patient to take drug with food.
• As appropriate, review all other significant and life-threatening adverse reactions and interactions, especially those related to the drugs, tests, and foods mentioned above.
