FDA cannot test all products on the market that contain potentially harmful hidden ingredients. It is clear from the results of our decade of testing that retailers and distributors, including online marketplaces, do not effectively prevent these types of potentially harmful products from being sold to consumers. Consumers should use caution when considering purchasing these types of products. These products may cause potentially serious side effects and may interact with medications or dietary supplements a consumer is taking. The public notifications listed below include those products FDA testing found to contain active drug ingredients not listed on the product labels, including some with ingredients found in prescription drugs. FDA is notifying consumers of certain products promoted for arthritis and pain management that have been found to contain hidden ingredients and may pose a significant health risk.
