Products found to contain undeclared medicines

The United States: Public Notification: Mezo was found to contain undeclared drug substance benzylsibutramine
The Food and Drug Administration (FDA) is advising consumers not to purchase or use Mezo, a product promoted and sold for weight loss on various websites and in some retail stores. FDA laboratory analysis confirmed that Mezo contains benzylsibutramine, a substance structurally similar to sibutramine. Sibutramine is a controlled substance that was removed from the market in October 2010 for safety reasons. Sibutramine is known to substantially increase blood pressure and/or pulse rate in some patients and may present a significant risk for patients with a history of coronary artery disease, congestive heart failure, arrhythmias, or stroke. This product may also interact, in life-threatening ways, with other medications a consumer may be taking.

Consumers should stop using this product immediately and throw it away. Consumers who have experienced any negative side effects should consult a health care professional as soon as possible.

Please refer to the following website in FDA for details:

In Hong Kong, the above product is not a registered pharmaceutical product.
