Zocef CV (Cefuroxime Axetil) Pediatric Dosing
The recommended pediatric dose of cefuroxime axetil (Zocef CV) is 20-50 mg/kg/day divided into two doses every 12 hours, with a maximum of 500 mg per dose. 1
Standard Dosing Guidelines
Oral Cefuroxime Axetil Dosing
- 20-50 mg/kg/day divided every 12 hours is the established pediatric dose 1
- Maximum single dose: 500 mg 1
- The dose should not exceed adult dosing limits 1
Parenteral Cefuroxime (IV/IM) Dosing for Reference
- 100-200 mg/kg/day divided every 6-8 hours for severe infections 1
- Maximum single dose: 1500 mg 1
- For pediatric patients above 3 months: 50-100 mg/kg/day in divided doses every 6-8 hours for most infections 2
- Higher dosage of 100 mg/kg/day should be used for more severe infections 2
Clinical Context and Indications
When Cefuroxime Axetil is Appropriate
- Community-acquired pneumonia caused by Streptococcus pneumoniae with penicillin MIC <2.0 μg/mL 1
- Alternative therapy to amoxicillin or amoxicillin/clavulanate for respiratory tract infections 1
- Beta-lactamase producing organisms including Haemophilus influenzae 1
- Upper and lower respiratory tract infections, otitis media, sinusitis 3, 4
Important Prescribing Considerations
- Cefuroxime axetil should be given with food to enhance absorption - bioavailability is 68% when taken after meals 3
- The drug is particularly useful when beta-lactamase-producing strains are suspected 4
- Amoxicillin remains first-line for most pediatric community-acquired pneumonia; cefuroxime axetil is an alternative 1
Age-Specific Cautions
Neonates and Young Infants
- Infants under 3 months: Use parenteral cefuroxime with caution; dose is 50 mg/kg twice daily 5
- Half-life is prolonged in neonates <4 days old (5.8 hours vs 1.6-3.8 hours in older infants) 5
- All infants <6 months with pneumonia should be hospitalized regardless of antibiotic choice 1
Renal Impairment
- Dosage adjustment required in children with renal insufficiency, following adult guidelines proportionally 2
- Cefuroxime is dialyzable; additional dose needed after hemodialysis 2
Common Pitfalls to Avoid
- Do not underdose: The 20 mg/kg/day dose may be insufficient for serious infections; use 40-50 mg/kg/day for pneumonia 1
- Do not confuse oral and IV formulations: Oral cefuroxime axetil dosing (20-50 mg/kg/day) differs significantly from IV cefuroxime (100-200 mg/kg/day) 1, 2
- Ensure adequate food intake: Administration without food significantly reduces absorption 3
- Consider atypical pathogens: In school-aged children (≥5 years), if Mycoplasma pneumoniae is suspected, a macrolide is preferred over cefuroxime 1
