Belviq Frequently Asked Questions

What’s the difference between Belviq, Belviq XR and Lorcaserin?

Lorcaserin is the drug’s medical name.  Belviq is the brand name and how it is marketed by its manufacturer, Eisai, Inc.   Belviq XR is an extended-release form of Belviq prescribed as one daily dose as opposed to twice daily.

Why did the FDA ask the Belviq manufacturer to remove the drug from the market?

The FDA asked Eisai, the manufacturer of Belviq and Belviq XR, to voluntarily withdrawal the weight-loss pill because a randomized safety clinical trial showed an increase risk of cancer.   The FDA believes the risk of taking Belviq outweighs the benefit of the weight loss drug.

The safety trial was conducted as a requirement when the FDA approved the drug in 2012.  The trial was to evaluate the risk of cardiovascular problems.  Instead of finding heart problems, the trial showed people who took the weight loss drug Belviq had an increased risk of pancreatic cancer, colorectal cancer and lung cancer

What should I do if I’m taking Belviq?

The FDA recommends patients stop taking Belviq and talk to their doctors about other weight-loss medicines or programs.  Belviq tablets should be taken to a drug take back location.  If you can’t get to a location, the FDA recommends:

  • Mixing Belviq tablets with an unappealing substance such as dirt or cat litter. Do not crush them.
  • Put the mixture in a sealed bag.
  • Throw the bag in your home trash.
  • Remove all labeling from the bottles and then recycle as appropriate

If you’ve taken Belviq and had side effects, the FDA recommends you report your issues to the FDA MedWatch program.
