The Food and Drug Administration (FDA) is advising consumers not to purchase or use Yanhee Slim, a product promoted and sold for weight loss on various websites.

FDA laboratory analysis confirmed that Yanhee Slim contains lorcaserin, a controlled substance and the active ingredient in the FDA-approved prescription drug Belviq®, used for chronic weight management in some overweight or obese adults. Lorcaserin may cause psychiatric disturbances and impairments in attention or memory. This product may also interact, in life-threatening ways, with other medications a consumer may be taking.

Health care professionals and patients are encouraged to report adverse events or side effects related to the use of these products to the FDA's MedWatch Safety Information and Adverse Event Reporting Program:

Complete and submit the report online at MedWatch Online Voluntary Reporting Form, or;
Download and complete the form, then submit it via fax at 1-800-FDA-0178.

Note: This notification is to inform the public of a growing trend of dietary supplements or conventional foods with hidden drugs and chemicals. These products are typically promoted for sexual enhancement, weight loss, and body building and are often represented as being “all natural.” FDA is unable to test and identify all products marketed as dietary supplements that have potentially harmful hidden ingredients. Consumers should exercise caution before purchasing any product in the above categories.
