Liver failure can result from an unintentional overdosage of what over-the-counter pain reliever?

Acetaminophen can result in liver failure 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 some patient groups (e.g., older adults, patients with pre-existing liver problems). Aspirin, ibuprofen, and naproxen are more likely to cause kidney damage than liver damage.
