Dosage adjustment

• Renal impairment


• Hypersensitivity to cephalosporins or penicillins

• Renal failure


Use cautiously in:

• renal or hepatic impairment

• pregnant or breastfeeding patients

• children.


• Obtain specimens for culture and sensitivity testing as necessary before starting therapy.

• Give drug with food.

Adverse reactions

CNS: headache, dizziness, drowsiness, hyperactivity, hypotonia, insomnia, confusion, seizures

GI: nausea, vomiting, diarrhea, abdominal pain, dyspepsia, pseudomembranous colitis

GU: hematuria, vaginal candidiasis, genital pruritus, renal dysfunction, toxic nephropathy

Hematologic: eosinophilia, aplastic anemia, hemolytic anemia, hemorrhage, bone marrow depression, hypoprothrombinemia

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

Drug-food. Moderate- or high-fat meal: increased drug bioavailability

Patient monitoring

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.

Patient teaching

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.

They administrated two second-generation antibiotics (cephalosporin and cefprozil) in healthy individuals and showed that antibiotics altered the microbiome of healthy volunteers in an interindividual manner, allowing the emergence of potentially pathogenic Enterobacteriaceae--in a subgroup of patients--probably related to a decreased initial gut microbiome diversity in those individuals.

Antimicrobial susceptibility testing was performed on Mueller-Hinton agar (Merck, Germany) using disk diffusion (Kirby Bauer's) technique according to Clinical and Laboratory Standards Institute (CLSI) guidelines The following: Cefotaxime 30ig, NalidixicAcid 30ig, Trimethoprim-sulphamethoxazole 30ig, Ceftazidime 30ig, piperacillin-tazobactam , Co-Amoxiclav 10ig, Nitrofurantoin 300ig, Imipenem 10ig, Meropenem 10ig, Ampicillin 30ig, Cefoxitin 30ig, Gentamicin10ig, Cefixime 5ig, Cefepime 30ig, Carbenicillin 100g, Cefprozil 30ig and Tetracycline 30ig.Among 436 samples tested, 50 samples of bacteria were resistant to antibiotics which were isolated.
Short-course therapy with several antibiotics including the cephalosporins (cefuroxime, cefprozil, cefpodoxime) has been shown to be non-inferior to a 10-day course of penicillin
Cefprozil and Cefuroxime) are used primarily for respiratory tract infections because they are more effective against H.
Empirical antibiotic which can be selected for oral administration include amoxycillin clavulanate, TMP-SMX, cefixime, sefpodoxim, cefprozil, cefuroxime axetil and cefalexin.
In regions where there is a high prevalence of [beta]-lactamase resistance, amoxicillin with clavulanate or second or third-generation cephalosporins (e.g., cefuroxime, cefpodoxime, cefprozil) have been reported to provide broader coverage.
