The drugs the FDA warns could be tainted:
The FDA warning comes after an analysis found that the "undeclared active pharmaceutical ingredients" in some of the products contained a controlled substance, a drug not approved for marketing in the United States and a suspected cancer-causing agent.
According to the FDA:
These weight loss products, some of which are marketed as "dietary supplements," are promoted and sold on various Web sites and in some retail stores. Some of the products claim to be "natural" or to contain only "herbal" ingredients, but actually contain potentially harmful ingredients not listed on the product labels or in promotional advertisements. These products have not been approved by the FDA, are illegal and may be potentially harmful to unsuspecting consumers.To learn more, click here.

The FDA advises consumers who have used any of these products to stop taking them and consult their healthcare professional immediately. The FDA encourages consumers to seek guidance from a healthcare professional before purchasing weight loss products.
"These tainted weight loss products pose a great risk to public health because they contain undeclared ingredients and, in some cases, contain prescription drugs in amounts that greatly exceed their maximum recommended dosages," said Janet Woodcock, M.D., director, Center for Drug Evaluation and Research, FDA.
"Consumers have no way of knowing that these products contain powerful drugs that could cause serious health consequences. Therefore FDA is taking this action to protect the health of the American public."
