Weight-Loss Products Containing Unlisted Drugs

The Food and Drug Administration recently identified 28 weight-loss products sold in the United States that contain prescription-only medicines. These drugs aren't listed on the products' labels, so consumers could have been unwittingly putting themselves at risk by using these products. Here are the four active ingredients the FDA found and the weight-loss products that contained each of them.

Sibutramine

This drug is a powerful appetite suppressant found in the prescription drug Meridia. It should be used only under a doctor's supervision because it can cause heart attacks, strokes, and heart palpitations, particularly in those with a history of high blood pressure or heart problems.
