What side effects can this medication cause?[edit | edit source]

The most common side effects of this medicine include:


What special precautions should I follow?[edit | edit source]

  • Clostridium difficile associated diarrhea (CDAD) has been reported with use of nearly all antibacterial agents, including cefprozil tablets, and may range in severity from mild diarrhea to fatal colitis. Treatment with antibacterial agents alters the normal flora of the colon leading to overgrowth of C. difficile.
  • If CDAD is suspected or confirmed, ongoing antibiotic use not directed against C. difficile may need to be discontinued. Appropriate fluid and electrolyte management, protein supplementation, antibiotic treatment of C. difficile, and surgical evaluation should be instituted as clinically indicated.
  • Prescribing cefprozil tablets in the absence of a proven or strongly suspected bacterial infection or a prophylactic indication is unlikely to provide benefit to the patient and increases the risk of the development of drug-resistant bacteria.
  • Cephalosporins, including cefprozil, should be given with caution to patients receiving concurrent treatment with potent diuretics since these agents are suspected of adversely affecting renal function.
  • Cefprozil should be prescribed with caution in individuals with a history of gastrointestinal disease particularly colitis.
  • Positive direct Coombs’ tests have been reported during treatment with cephalosporin antibiotics.
  • Patients should be counseled that antibacterial drugs including cefprozil tablets should only be used to treat bacterial infections. They do not treat viral infections (e.g., the common cold).
  • Skipping doses or not completing the full course of therapy may (1) decrease the effectiveness of the immediate treatment and (2) increase the likelihood that bacteria will develop resistance and will not be treatable by cefprozil tablets or other antibacterial drugs in the future.
  • Diarrhea is a common problem caused by antibiotics which usually ends when the antibiotic is discontinued. Sometimes after starting treatment with antibiotics, patients can develop watery and bloody stools even as late as two or more months after having taken the last dose of the antibiotic. If this occurs, patients should contact their physician as soon as possible.
  • Cephalosporin antibiotics may produce a false positive reaction for glucose in the urine with copper reduction tests (Benedict’s or Fehling’s solution or with Clinitest tablets), but not with enzyme-based tests for glycosuria (e.g., Clinistix).
  • Caution should be exercised when cefprozil is administered to a nursing woman, since the effect of cefprozil on nursing infants is unknown.
  • If you have phenylketonuria, you should know that cefuroxime suspension is sweetened with aspartame that forms phenylalanine.
