The FDA is advising consumers not to buy or use Ultra Bon, a product promoted for arthritis, pain and osteoporosis. The product is sold on various websites, including eBay, and may also be available in some retail stores. FDA laboratory analysis confirmed that Ultra Bon contains diclofenac, which is not listed on its label.

The FDA said diclofenac is a nonsteroidal anti-inflammatory drug, or NSAID. NSAIDs can increase the risk of serious heart problems, including heart attack and stroke, and gastrointestinal problems such as bleeding, ulcers or life-threatening tears in the stomach or intestinal lining. Diclofenac can interact with other medicines, especially products containing other NSAIDs. The FDA asks health care professionals and consumers to report related adverse events or side effects to its MedWatch program.
