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

Recommended Dosage of Ibuprofen

The recommended dose of ibuprofen is 400-800 mg every 6 hours, with a maximum daily dose of 3200 mg. 1, 2

Adult Dosing Guidelines

General Pain Management

• For mild to moderate pain: 400 mg every 4-6 hours as needed 2
• For more severe pain: 400-800 mg every 6 hours 1
• Maximum initial dose: 800 mg 1
• Maximum daily dose: 3200 mg (do not exceed this amount) 2

Specific Conditions

• Rheumatoid arthritis and osteoarthritis:

  • Recommended range: 1200-3200 mg daily (divided as 400 mg, 600 mg, or 800 mg three or four times daily) 2
  • Patients with rheumatoid arthritis often require higher doses than those with osteoarthritis 2
  • Use the smallest effective dose that provides adequate control 2

• Dysmenorrhea (menstrual pain):

  • 400 mg every 4 hours as needed, beginning at earliest onset of pain 2

• Acute pain in emergency settings:

  • 400-600 mg orally every 4-6 hours 1

Important Considerations

Duration of Action

• Ibuprofen 400 mg provides at least 6 hours of pain relief compared to 4-6 hours for ibuprofen 200 mg 3
• The smallest clinically useful dose of ibuprofen is 200 mg 3

Safety Precautions

• Use the lowest effective dose for the shortest duration consistent with treatment goals 2
• Administer with meals or milk if gastrointestinal complaints occur 2
• Avoid taking more than 3200 mg per day to prevent adverse effects 1, 2

Special Populations

• Older adults: Use caution due to higher risk of adverse effects, particularly gastrointestinal toxicity 1
• Pregnancy: Safe in first and second trimester (up to 28 weeks) for short-term use (7-10 days); avoid in third trimester 1
• Patients with cardiovascular disease: Use with caution due to potential cardiovascular risks 1

Common Pitfalls

• Exceeding recommended dosage: Studies show that approximately 11% of ibuprofen users exceed the daily dosing limit 4
• Incorrect dosing in children: Over 50% of caregivers give inaccurate doses of ibuprofen to children, particularly to infants under 1 year 5
• Failure to recognize multiple NSAID sources: Many patients don't recognize all products they take as NSAIDs, risking overdose 4

Contraindications

• Aspirin/NSAID-induced asthma 1
• Severe renal or hepatic impairment 1
• History of gastrointestinal bleeding or ulceration 1
• Uncontrolled hypertension or severe heart failure 1

Combination Therapy

• Combining ibuprofen with acetaminophen (paracetamol) can provide better pain relief than either drug alone 6
• Ibuprofen 400 mg + acetaminophen 1000 mg shows superior efficacy compared to ibuprofen 400 mg alone for acute pain 6

Remember that while ibuprofen is effective for pain management, it should be used at the lowest effective dose for the shortest duration to minimize potential adverse effects.
