Public Notification: “Japan Rapid Weight Loss Diet Pills Green” Contains Hidden Drug Ingredient

[04-03-2012] The Food and Drug Administration (FDA) is advising consumers not to purchase or use “Japan Rapid Weight Loss Diet Pills Green,” a product for weight loss sold on various websites, such as www.amazon.com, and distributed by Xiushentang. 

FDA laboratory analysis confirmed that “Japan Rapid Weight Loss Diet Pills Green” contains undeclared phenolphthalein.  Phenolphthalein is a solution used in chemical experiments and a suspected cancer-causing agent that is not approved for marketing in the United States.  The FDA has classified phenolphthalein as “not generally recognized as safe and effective.” Phenolphthalein has also been found to be genotoxic in that it can damage or cause mutations to DNA.

Consumers should stop using these products immediately and throw them away.  Consumers who have experienced any negative side effects should consult a health care professional as soon as possible. 
Healthcare 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:

Note: This notification is to inform the public of a growing trend of products marketed as 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.
