The FDA has implemented rules that require drug companies to place stronger warnings on the labels of common over-the-counter pain relievers about the risk of liver damage and stomach bleeding. The FDA’s Matthew Ray Holman, PhD, says the new warnings are necessary “to raise consumer awareness about the potential for liver damage when using acetaminophen (such as Tylenol) and the potential for stomach bleeding when using a nonsteroidal anti-inflammatory drug,” commonly called an NSAID. NSAIDs include aspirin, ibuprofen, naproxen and ketoprofen.
