What is the recommended dose of ibuprofen (nonsteroidal anti-inflammatory drug (NSAID)) for pediatric patients?

Pediatric Ibuprofen Dosing Guidelines

The recommended dose of ibuprofen for pediatric patients is 5-10 mg/kg every 6-8 hours, with a maximum of 40 mg/kg/day, and children under 12 years should not exceed this dosage without physician guidance. 1, 2

Age-Based Dosing Recommendations

Infants (3-12 months)

• Dosage: 5-10 mg/kg per dose
• Frequency: Every 6-8 hours as needed
• Maximum daily dose: 30-40 mg/kg/day
• Important note: Only use in infants older than 3 months weighing more than 5-6 kg, with special attention to hydration 2

Children (1-12 years)

• Dosage: 5-10 mg/kg per dose
• Frequency: Every 6-8 hours as needed (3-4 times daily)
• Maximum daily dose: 40 mg/kg/day, not to exceed adult maximum

Adolescents (≥12 years) and Adults

• Dosage: 200-400 mg per dose
• Frequency: Every 4-6 hours as needed
• Maximum daily dose: 1200 mg/day (OTC use) unless directed by a doctor 1

Weight-Based Dosing Chart

For precision in dosing, use this weight-based approach:

• <15 kg: 5-10 mg/kg per dose
• 15-23 kg: 100-150 mg per dose
• 24-40 kg: 150-200 mg per dose
• >40 kg: Adult dosing (200-400 mg per dose)

Administration Considerations

• Oral route preferred: Rectal administration shows erratic absorption, especially in young infants 2
• Take with food: Administer with food or milk to reduce gastrointestinal irritation
• Liquid formulations: Preferred for younger children for dosing accuracy
• Duration: Use the shortest effective duration to minimize adverse effects

Clinical Efficacy

Ibuprofen has been shown to be:

• Effective for fever reduction with maximum effect at 3-4 hours post-administration 3
• Comparable or superior to acetaminophen as both an analgesic and antipyretic 3, 4
• Longer duration of action compared to acetaminophen 3

Safety Considerations

• Hydration status: Ensure adequate hydration, especially in febrile children
• Renal function: Use caution in children with impaired renal function
• Dosing errors: Carefully record all dose times to avoid exceeding maximum recommended doses
• Contraindications: Avoid in children with known hypersensitivity to NSAIDs, active GI bleeding, or severe renal impairment

Common Pitfalls to Avoid

1. Exceeding recommended dosage: Studies show 11% of children receive excessive ibuprofen doses 4
2. Confusing ibuprofen with acetaminophen: These medications have different dosing schedules and maximum daily limits
3. Inadequate dosing: Underdosing may lead to insufficient pain or fever control
4. Prolonged use without medical supervision: Long-term use should be monitored by healthcare providers

Ibuprofen is generally well-tolerated in children, with evidence suggesting better tolerance in children than adults 3. For fever management, ibuprofen may be considered as a first-line option, with the option to add acetaminophen if needed for additional fever control 4.
