An unintentional overdosage of what over-the-counter pain reliever can result in liver failure?

Liver failure can result from acetaminophen when taken at higher than recommended doses or used in combination with alcohol. Patients should take no more than 4,000 mg per day; recommended doses may be lower for several patient groups (e.g., older adults, patients with pre-existing liver problems). Aspirin, ibuprofen, and naproxen are more likely to result in kidney damage than liver damage.
