"it may take 191 tablets (200mg/tablet) or a total of 38,160 mg for a 60-kg man to die from acute ibuprofen overdose. The effects of ibuprofen at lesser doses (600-800mg) also include upset stomach, which can lead to internal bleeding and death, over a long time. Taking higher doses (1200-1600mg) can make you sick and throw up, but not enough to kill you at once."
