From the U.S. Food and Drug Administration:
ISSUE: FDA has requested that the manufacturer of Belviq, Belviq XR (lorcaserin) voluntarily withdraw the weight-loss drug from the U.S. market because a safety clinical trial shows an increased occurrence of cancer. The drug manufacturer, Eisai Inc,. has submitted a request to voluntarily withdraw the drug. When FDA approved lorcaserin in 2012, we required the drug manufacturer to conduct a clinical trial to evaluate the risk of cardiovascular problems. A range of cancer types was reported, with several different types of cancers occurring more frequently in the lorcaserin group, including pancreatic, colorectal, and lung.
BACKGROUND: In January 2020, FDA announced we were reviewing clinical trial data and alerted the public about a possible risk of cancer associated with lorcaserin based on preliminary analysis of the data.
RECOMMENDATION: PatientsPatients should stop taking lorcaserin and talk to your health professionals about alternative weight-loss medicines and weight management programs.
I never ran across a patient taking it, nor did I ever prescribe it. There are better ways to lose weight.
