Belviq withdrawal background

Prescription weight-loss drugs Belviq and Belviq XR are marketed as a way to help patients who are struggling with obesity feel full while on reduced-calorie diets. The FDA approved the drug in 2012, but required Eisai to complete a clinical trial to assess the safety and efficacy of the drug.

After reviewing the trial data, the FDA announced in January 2020 that the drug was a possibly associated with an increased risk of several types of cancer, including:

• Pancreatic
• Colorectal
• Lung 

Within weeks of its announcement, the FDA reported that it asked Eisai to remove the drug from the U.S. market, and that in response Eisai asked the FDA to voluntarily withdraw the drug.

As a result, the FDA told health professionals they should stop prescribing Belviq and generic lorcaserin, tell patients taking Belviq or lorcaserin about the increased cancer occurrence seen in the clinical trial, and discuss with patients alternative medicine or weight loss strategies.  

Health professionals and patients who observe adverse side effects or a cancer such pancreatic, colorectal, or and lung cancer is found in a patient who took Belviq should n report the issue to the FDA.
