What is the recommended dose of ibuprofen (Nonsteroidal Anti-Inflammatory Drug (NSAID)) for adults?

Recommended Ibuprofen Dosing for Adults

The recommended standard dose of ibuprofen for adults is 400-600 mg orally every 4-6 hours as needed for pain, with a maximum daily dose of 3200 mg. 1, 2

Standard Dosing Guidelines

• For acute pain management, 400-600 mg orally every 4-6 hours is recommended 2
• For antipyretic (fever-reducing) effects, 200-400 mg every 4-6 hours is recommended, with a maximum daily dose of 1200 mg 3
• For chronic conditions like rheumatoid arthritis and osteoarthritis, doses range from 1200-3200 mg daily (divided into 3-4 doses) 1
• The smallest clinically effective dose for pain relief is 200 mg 4

Dosing Algorithm

1. Initial dosing for most adults:

   • Start with 400 mg every 4-6 hours for acute pain 1, 5
   • If inadequate relief, may increase to 600 mg every 6 hours 1

2. For chronic inflammatory conditions:

   • Begin with 1200 mg daily in divided doses 1
   • Titrate up to 3200 mg daily if needed based on response 1
   • Use the lowest effective dose for the shortest duration 2

Safety Considerations

• Gastrointestinal risk increases with higher doses and prolonged use 3, 6

  • Consider gastroprotection with proton pump inhibitors for chronic use at higher doses 3
  • Ibuprofen has lower GI risk compared to aspirin at OTC doses 7, 6

• Special populations requiring dose adjustment:

  • Older adults should start with lower doses due to increased risk of adverse effects 2
  • Patients with renal impairment may require lower doses 2
  • Patients with cardiovascular disease should use the lowest effective dose for shortest duration 2

Efficacy Considerations

• Ibuprofen 400 mg provides approximately 6 hours of analgesia compared to 4-6 hours for ibuprofen 200 mg 4
• Research shows no significant difference in analgesic efficacy between 400 mg, 600 mg, and 800 mg doses for short-term pain relief in emergency settings 5
• Ibuprofen is as effective as aspirin and paracetamol for OTC indications but with lower risk of gastrointestinal toxicity 7, 6

Common Pitfalls to Avoid

• Combining ibuprofen with other NSAIDs increases risk without providing additional benefit 2
• For patients taking low-dose aspirin for cardioprotection, take ibuprofen at least 30 minutes after immediate-release aspirin or 8 hours before aspirin 2
• Avoid prolonged use without reassessing benefits and risks 2
• Do not exceed 3200 mg total daily dose 1
