After the Food and Drug Administration (FDA) approves a product and it is on the market, FDA continues to monitor unexpected and undesirable side effects (adverse events) of that product.
Health care professionals and consumers may report side effects, product quality problems, product use errors, or therapeutic failure with the use of medical products to FDA's MedWatch Adverse Event Reporting program either online, by regular mail, by fax, or by phone.

FDA laboratory tests showed that the counterfeit Alli has a different active ingredient, a stimulant found in a prescription weight-loss drug.

The counterfeit Alli looks similar to the authentic product, with a few notable differences (see photos3).
Some previously recalled products were reported to have an unusual moldy, musty, or mildew-like odor that was related to nausea, stomach pain, vomiting, and diarrhea. The odor is caused by a compound believed to result from the breakdown of a chemical used to treat wooden pallets that transport and store packaging materials.

The risk: The health effects of the compound believed to cause the symptoms have not been well studied. To date, all of the observed events reported were temporary and not serious.
