FDA panels had urged new warnings for acetaminophen in 1977 and 2002, but the FDA claimed "laborious" work delayed their action. The recommended warnings apply to acetaminophen, a common ingredient in products like Tylenol (potential liver damage), and for NSAIDs, or nonsteroidal anti-inflammatory drugs, such as aspirin, ibuprofen, naproxen and ketoprofen (may cause stomach bleeding).

While most people tolerate the recommended dosage well, many people do not realize the dangers of taking too much or combining the medicines with alcohol. Or they may unknowingly use more than one product that contains the same ingredient and accidentally overdose.
