Can You Take Two Tablets of Advil Every 6 Hours?

Yes, taking two 200mg tablets of Advil (400mg total) every 6 hours is safe and appropriate for most adults, as this falls well within the FDA-approved maximum daily dose of 3200mg and represents the standard effective dose for acute pain management. 1

Standard Dosing Guidelines

The FDA-approved dosing for ibuprofen is 400mg every 4-6 hours as needed for pain relief. 1 This means:

  • Two 200mg tablets (400mg total) every 6 hours = 1600mg per day maximum
  • This is exactly half of the maximum daily dose of 3200mg 1
  • The 400mg dose has been proven as effective as higher doses (600-800mg) for most acute pain conditions 2

Duration of Safe Use

For over-the-counter use without medical supervision, limit ibuprofen to 10 days maximum. 3, 4

  • At 400mg every 6 hours, you can safely use this regimen for 5-10 days for acute pain 3
  • Beyond 2 weeks requires medical monitoring every 3 months (blood pressure, kidney function, liver tests, complete blood count, fecal occult blood) 3

When This Dose Is NOT Safe

Avoid or use extreme caution if you have: 3, 4

  • Age over 60 years - significantly increased risk of all adverse effects 3
  • History of peptic ulcer disease - 5% risk of recurrent bleeding within 6 months 3
  • Kidney disease - NSAIDs can worsen renal function 3
  • Heart failure or cardiovascular disease - avoid entirely 5, 3
  • Taking blood thinners (warfarin, aspirin, other anticoagulants) - increases bleeding risk 5-6 times 3
  • Taking other NSAIDs - never combine ibuprofen with naproxen, ketorolac, or other NSAIDs 6
  • Asthma with history of nasal polyps - risk of severe bronchospasm 3

Critical Safety Rules

Stop ibuprofen immediately and seek medical attention if: 3

  • Black or bloody stools (gastrointestinal bleeding)
  • Decreased urine output or swelling (kidney injury)
  • Worsening blood pressure
  • Severe stomach pain
  • Worsening asthma symptoms

Timing With Other Medications

If taking low-dose aspirin for heart protection: 3

  • Take ibuprofen at least 30 minutes AFTER immediate-release aspirin, OR
  • Take ibuprofen at least 8 hours BEFORE aspirin
  • Ibuprofen can block aspirin's cardioprotective effects if taken incorrectly

Never combine with other NSAIDs (naproxen/Aleve, ketorolac/Toradol, diclofenac) - this dramatically increases toxicity without improving pain relief 6

Alternative Considerations

Acetaminophen (Tylenol) is safer for high-risk patients: 3

  • Up to 3000mg daily (650mg every 6 hours)
  • No gastrointestinal, kidney, or cardiovascular risks
  • Slightly less effective than ibuprofen but much safer long-term 3

You can alternate ibuprofen with acetaminophen for better pain coverage without exceeding maximum doses of either medication 6

Bottom Line

Your proposed regimen of 400mg every 6 hours (two 200mg tablets) is safe, effective, and FDA-approved for most healthy adults under age 60 without the contraindications listed above. 1, 4 This dose provides optimal pain relief with minimal risk when used for short-term acute pain (under 10 days). 3, 7
