How much ibuprofen is too much?
Last updated September 3, 2026.
Over the counter, adults top out at 1,200 mg a day - six 200 mg tablets, no more than 6 doses in 24 hours, every 4 to 6 hours. Prescription doses can reach 3,200 mg a day, but only under a doctor's direction. Too much strips the stomach lining and strains kidneys: stomach pain, vomiting blood or coffee-ground material, black tarry stools, ringing ears, drowsiness - and large overdoses bring confusion, seizures, kidney failure. The common overdose is accidental: cold and flu combos hide ibuprofen - check every label. Taken too much? Call poison control (1-800-222-1222, US) or seek urgent care without waiting for symptoms.

What to do
- Cap at 1,200 mg over the counter: six 200 mg tablets per day, spread out.
- Audit combination products: cold and flu remedies often contain ibuprofen.
- Overdose is a now-call: poison control 1-800-222-1222 (US), before symptoms.
- Pain that outlives the ceiling needs a doctor: not a higher dose.
