Ibuprofen Pediatric Dose — Analgesia & Antipyresis
Ibuprofen is a nonsteroidal anti-inflammatory drug (NSAID) that exerts analgesic, antipyretic, and anti-inflammatory effects primarily through reversible inhibition of cyclooxygenase (COX-1 and COX-2) enzymes, reducing prostaglandin synthesis. It is widely used in pediatrics for the management of mild-to-moderate pain and fever in appropriate age groups. Its oral availability and favorable tolerability profile make it one of the most commonly utilized analgesics in both inpatient and outpatient pediatric settings.
Pediatric Dosing
- Dose: 10 mg/kg per dose PO every 6 hours as needed
- Maximum single dose: 800 mg/dose
- Age restriction: Not recommended for routine antipyretic use in patients younger than 6 months of age.
For a 20 kg child: 20 × 10 mg/kg = 200 mg per dose PO every 6 hours PRN. For a 70 kg adolescent: 70 × 10 mg/kg = 700 mg, which remains below the 800 mg single-dose cap. An 80 kg adolescent would be capped at 800 mg/dose regardless of weight-based calculation.
Indications and Clinical Context
Ibuprofen is indicated for mild-to-moderate pain and fever reduction in pediatric patients 6 months of age and older. Common clinical applications include pain associated with musculoskeletal injury, headache, dental procedures, post-operative discomfort, and fever management in the context of infectious illness. As a peripherally and centrally acting analgesic with anti-inflammatory properties, ibuprofen is particularly useful when an inflammatory component contributes to the pain source.
Standard pediatric pain management guidelines support ibuprofen as a first-line oral analgesic for appropriate indications. Its use in patients younger than 6 months is not recommended for routine antipyresis given limited safety and efficacy data in this age group; consult institutional protocol for pain management in neonates and young infants.
Administration and Monitoring
Ibuprofen is administered orally (PO) as a suspension, chewable tablet, or standard tablet depending on the patient’s age and ability to swallow. It should be given with food or milk to reduce gastrointestinal irritation. The dosing interval is every 6 hours as needed; avoid scheduled continuous use beyond the shortest effective duration. Monitor for common adverse effects including gastrointestinal upset, nausea, and — with prolonged use — renal impairment or elevated hepatic enzymes.
- Avoid in patients with known hypersensitivity to NSAIDs or aspirin-sensitive asthma.
- Use with caution in patients with renal insufficiency, dehydration, or thrombocytopenia.
- Ibuprofen is contraindicated in neonates and should not be used routinely in infants under 6 months of age for antipyresis.
- Do not exceed 800 mg per single dose regardless of weight.
- Consult institutional protocol for use in complex patients or those on concurrent nephrotoxic agents.
