Penicillin - getting prescribing right for children

Area of Science:

• Pediatric Pharmacology
• Antimicrobial Stewardship

Background:

• Penicillins are frequently prescribed for pediatric infections.
• Existing product information may not provide optimal dosing or indications for children.
• Alternative antibiotics might be preferred for certain pediatric conditions.

Purpose of the Study:

• To highlight discrepancies in pediatric penicillin dosing recommendations.
• To emphasize the importance of evidence-based guidelines for pediatric antibiotic use.
• To guide appropriate selection, route, dosage, and duration of oral penicillins in children.

Main Methods:

• Review of product information for pediatric penicillin recommendations.
• Comparison with reputable antibiotic guidelines (e.g., Therapeutic Guidelines: Antibiotic).
• Analysis of weight-based dosing strategies versus standard dosing.

Main Results:

• Pediatric penicillin dosing often necessitates weight-based calculations (mg/kg).
• Maximum adult doses should not be exceeded, even with weight-based calculations.
• Specific oral liquid volumes for higher weight-based doses of amoxicillin/flucloxacillin require careful checking to ensure sufficient supply for treatment.

Conclusions:

• Relying solely on product information for pediatric penicillin dosing can be suboptimal.
• Utilizing authoritative antibiotic guidelines is crucial for appropriate pediatric prescribing.
• Weight-based dosing, with attention to total volume, ensures effective and adequate penicillin therapy in children.
