Inhibits bacterial cell wall synthesis by binding to one or more of the penicillin-binding proteins (PBPs) which in turn inhibits the final transpeptidation step of peptidoglycan synthesis in bacterial cell walls, thus inhibiting cell wall biosynthesis. Bacteria eventually lyse due to ongoing activity of cell wall autolytic enzymes (autolysins and murein hydrolases) while cell wall assembly is arrested.

Concerns related to adverse effects:
• Elevated INR: May be associated with increased INR, especially in nutritionally-deficient patients, prolonged treatment, hepatic or renal disease.
• Hypersensitivity reactions: Serious and occasionally severe or fatal hypersensitivity (anaphylactic) reactions have been reported in patients receiving beta-lactam drugs. Before initiating therapy, carefully investigate previous penicillin, cephalosporin, or other allergen hypersensitivity. Use caution if given to a patient with a penicillin or other beta-lactam allergy because cross sensitivity among beta-lactam antibacterial drugs has been established. If an allergic reaction occurs, discontinue and institute appropriate therapy.
• Superinfection: Prolonged use may result in fungal or bacterial superinfection, including C. difficile-associated diarrhea (CDAD) and pseudomembranous colitis; CDAD has been observed >2 months postantibiotic treatment.
• Gastrointestinal disease: Use with caution in patients with a history of colitis.
• Renal impairment: Use with caution in patients with renal impairment; modify dosage in severe impairment.
• Seizure disorders: Use with caution in patients with a history of seizure disorder; cephalosporins have been associated with seizure activity, particularly in patients with renal impairment not receiving dose adjustments. Discontinue if seizures occur.
Concurrent drug therapy issues:
• Drug-drug interactions: Potentially significant interactions may exist, requiring dose or frequency adjustment, additional monitoring, and/or selection of alternative therapy. Consult drug interactions database for more detailed information.
Dosage form specific issues:
• Benzyl alcohol and derivatives: Some dosage forms may contain sodium benzoate/benzoic acid; benzoic acid (benzoate) is a metabolite of benzyl alcohol; large amounts of benzyl alcohol (≥99 mg/kg/day) have been associated with a potentially fatal toxicity (“gasping syndrome”) in neonates; the “gasping syndrome” consists of metabolic acidosis, respiratory distress, gasping respirations, CNS dysfunction (including convulsions, intracranial hemorrhage), hypotension, and cardiovascular collapse (AAP ["Inactive" 1997]; CDC 1982); some data suggests that benzoate displaces bilirubin from protein binding sites (Ahlfors 2001); avoid or use dosage forms containing benzyl alcohol derivative with caution in neonates. See manufacturer’s labeling.
• Phenylalanine: Some products may contain phenylalanine.
• Suspension/tablet bioequivalence: Tablets and oral suspension are not bioequivalent; do not substitute on a mg-per-mg basis.
• Tablets: Should not be crushed or chewed due to a strong, persistent bitter taste. Patients unable to swallow whole tablets should be prescribed the oral suspension.
Monitor renal, hepatic, and hematologic function periodically with prolonged therapy. Monitor prothrombin time in patients at risk of prolongation during cephalosporin therapy (nutritionally-deficient, prolonged treatment, renal or hepatic disease). Observe for signs and symptoms of anaphylaxis during first dose.
Pregnancy Risk Factor
Adverse events were not observed in animal reproduction studies. Cefuroxime crosses the placenta and reaches the cord serum and amniotic fluid. Placental transfer is decreased in the presence of oligohydramnios. Several studies have failed to identify an increased teratogenic risk to the fetus following maternal cefuroxime use.
During pregnancy, mean plasma concentrations of cefuroxime are 50% lower, the AUC is 25% lower, and the plasma half-life is shorter than nonpregnant values. At term, plasma half-life is similar to nonpregnant values and peak maternal concentrations after IM administration are slightly decreased. Pregnancy does not alter the volume of distribution. Cefuroxime is one of the antibiotics recommended for prophylactic use prior to cesarean delivery.
• Discuss specific use of drug and side effects with patient as it relates to treatment. (HCAHPS: During this hospital stay, were you given any medicine that you had not taken before? Before giving you any new medicine, how often did hospital staff tell you what the medicine was for? How often did hospital staff describe possible side effects in a way you could understand?)
• Patient may experience diarrhea. Have patient report immediately to prescriber severe injection site irritation, severe nausea, severe vomiting, bruising, bleeding, urinary retention, change in amount of urine passed, severe loss of strength and energy, chills, pharyngitis, vaginitis, hearing impairment, or signs of Clostridium difficile (C. diff)-associated diarrhea (abdominal pain or cramps, severe diarrhea or watery stools, or bloody stools) (HCAHPS).
• Educate patient about signs of a significant reaction (eg, wheezing; chest tightness; fever; itching; bad cough; blue skin color; seizures; or swelling of face, lips, tongue, or throat). Note: This is not a comprehensive list of all side effects. Patient should consult prescriber for additional questions.
