The maximum daily dose of ibuprofen is 3,200 mg. However, if you are taking that much ibuprofen, I would be asking you a lot of questions as to why and if you have been to the doctor or health care provider for further evaluation.
The highest recommended dosage is 800mg tablets three times a day. This would be the equivolent of four tablets of the OTC motrin or other ibuprofen brand three times a day. The LD50 of ibuprofen is 636mg/kg. So you're not going to DIE.
