The FDA is advising consumers not to buy or use Yuan Bone, a product promoted for joint pain online and possibly in some retail stores. The agency said laboratory analysis found acetaminophen, chlorpheniramine and diclofenac that were not listed on the product label.

The FDA said too much acetaminophen can cause liver damage, including liver failure and death. Chlorpheniramine may cause drowsiness and make it harder to think clearly or stay alert. The agency said diclofenac, a nonsteroidal anti-inflammatory drug, can increase the risk of serious heart and gastrointestinal problems and may interact with other medications.

The FDA asked health care professionals and consumers to report adverse events or side effects through its MedWatch program. The agency said it cannot test and identify all products marketed with potentially harmful hidden ingredients.
