Cefuroxime Pediatric Dose — Antimicrobial Reference
Cefuroxime is a second-generation cephalosporin antibiotic that exerts bactericidal activity by inhibiting bacterial cell wall synthesis through binding to penicillin-binding proteins. It provides reliable coverage against a broad range of gram-positive and gram-negative organisms, including Staphylococcus aureus, Streptococcus pneumoniae, Haemophilus influenzae, and selected Enterobacteriaceae. In pediatric practice, it is commonly used for serious infections including pneumonia, skin and soft tissue infections, urinary tract infections, and bone and joint infections.
Pediatric Dosing
- Dose: 50 mg/kg/dose IV every 8 hours
- Adult dose: 1.5 g IV every 8 hours
Doses should be calculated on a per-kilogram basis and should not exceed the standard adult dose of 1.5 g per dose. Consult institutional protocol for specific indication-based adjustments or renal dosing guidance.
Worked example: For a 20 kg child: 20 × 50 mg/kg = 1,000 mg (1 g) IV every 8 hours. For a 35 kg child: 35 × 50 mg/kg = 1,750 mg — dose capped at the adult maximum of 1.5 g IV every 8 hours.
Indications and Clinical Context
Cefuroxime IV is indicated for moderate-to-severe bacterial infections in pediatric patients where second-generation cephalosporin coverage is appropriate. Common indications include community-acquired pneumonia, complicated urinary tract infections, cellulitis, septic arthritis, and osteomyelitis. Its activity against beta-lactamase–producing H. influenzae makes it a useful choice in respiratory tract infections in children.
Selection of cefuroxime should be guided by local susceptibility patterns and clinical severity. In critically ill patients or those with suspected resistant organisms, escalation to broader-spectrum agents should be considered per institutional antimicrobial stewardship guidelines.
Administration and Monitoring
Cefuroxime is administered intravenously for serious infections. It is typically reconstituted and infused over 15–30 minutes as an intermittent IV infusion. Ensure IV access patency prior to administration; IO access may be used in emergent situations when IV access is unavailable.
- Route: Intravenous (IV); IO acceptable in emergencies
- Frequency: Every 8 hours
- Max single dose: 1.5 g (adult dose)
- Monitor for: Hypersensitivity reactions (rash, urticaria, anaphylaxis), nephrotoxicity with prolonged use, Clostridioides difficile–associated diarrhea, and superinfection
- Contraindications: Known hypersensitivity to cefuroxime, cephalosporins, or history of severe immediate hypersensitivity to penicillins (cross-reactivity is low but possible)
- Dose adjustment may be required in significant renal impairment — consult institutional protocol
