Contraindication

Hypersensitivity to cephalosporins.

Mode of Action

Cefuroxime binds to one or more of the penicillin-binding proteins (PBPs) which inhibits the final transpeptidation step of peptidoglycan synthesis in bacterial cell wall, thus inhibiting biosynthesis and arresting cell wall assembly resulting in bacterial cell death.

Precaution

Severe renal impairment; pregnancy, lactation; hypersensitivity to penicillins. Lactation: Drug excreted in breast milk; use with caution

Side Effect

>10% Diarrhea (4-11%; depends on duration) 1-10% Decreased hemoglobin or hematocrit (10%),Eosinophilia (7%),Nausea or vomiting (3-7%),Vaginitis (<5%),Transient rise in hepatic transaminases (2-4%),Diaper rash (3%),Increase in alkaline phosphatase (2%),Thrombophlebitis (2%),Increase in lactate dehydrogenase (1%) <1% Anemia,Cholestasis,Colitis,Dyspnea,Epidermal necrolysis,Increase in blood urea nitrogen (BUN) and creatinine,Jaundice,Nephritis,Prolonged prothrombin time (PT)/international normalized ratio (INR),Rash,Stevens-Johnson syndrome,Stomach cramps,Transient neutropenia and leukopenia,Urticaria Potentially Fatal: Anaphylaxis, nephrotoxicity, pseudomembranous colitis.

Pregnancy Category Note

Pregnancy Available data from published epidemiologic studies, case series, and case reports over several decades in pregnant women have not established drug-associated risks of major birth defects, miscarriage, or adverse maternal or fetal outcomes Lactation Based on several published case reports describing multiple lactating women receiving therapy via intravenous, intramuscular, and oral routes, drug is present in human milk; the highest maternal milk concentration described occurred in lactating women 8 hours after an intramuscular administration of 750 mg; allowing for an infant milk consumption of 150 mL/kg/day, the estimated breastfed infant dose would be less than 1% of adult dose No data are available on effects of drug on breastfed infant or on milk production; developmental and health benefits of breastfeeding should be considered along with the mother’s clinical need for therapy and any potential adverse effects on breastfed infant from drug or from underlying maternal condition

Interaction

May enhance the nephrotoxic effect of strong-acting diuretics (e.g. furosemide) and aminoglycosides. May enhance the effect of oral anticoagulants. May reduce the efficacy of OCs. Probenecid prolongs the excretion of cefuroxime and elevated peak serum level.
