Here is a summary of ibuprofen (Ibrufen) pediatric dosing from authoritative medical textbooks:

Ibuprofen — Pediatric Dosage

Standard Dosing

Parameter	Details
Dose	10 mg/kg per dose, orally
Frequency	Every 6–8 hours
Maximum daily dose	40 mg/kg/day, never exceeding 3,200 mg/day
Minimum age	≥ 6 months — contraindicated in infants < 6 months

Ibuprofen is the NSAID of choice in pediatric patients due to its favorable side-effect profile compared to other NSAIDs.

Indications in Children

Fever (antipyretic)
Pain (analgesic) — mild to moderate
Inflammatory conditions (e.g., juvenile idiopathic arthritis — higher doses under specialist guidance)
Postoperative pain (in combination with other analgesics)

Key Safety Points

Avoid in infants < 6 months — pharmacokinetic differences and ongoing renal development make it unsafe in this age group.
Renal caution: NSAIDs (including ibuprofen) can impair renal function; use with caution in dehydrated children.
GI effects: COX-1 inhibition can cause GI irritation; administer with food.
Do not use aspirin as an alternative in children — risk of Reye syndrome.
Alternating with acetaminophen (paracetamol) may offer slightly better fever/pain control but increases complexity and risk of dosing errors.
