What is Belviq? How does Belviq work?

Belviq (Lorcaserin) is a weight loss drug and a diet pill approved by the FDA in 2012 and was launched in the U.S. in June 2013. Eisai is the manufacturer of both Belviq and Belviq XR (the extended release options of the diet pill). Doctors prescribed Belviq (Lorcaserin) as a weight loss drug for adults who were obese or overweight and couldn’t lose weight with diet and exercise alone.

The Belviq diet drug is recommended to be used with a reduced-calorie diet and increased physical activity. The diet drug lorcaserin helps people lose weight by increasing a person’s feeling of being full so that she eats less food.

A normal BMI is considered to be 18.5 to 24.9 kg/m². Doctors prescribed the weight loss pill to people with the following BMI:

  • 30 kg/m² or greater (considered to be obese)
  • 27 kg/m² or greater (considered to be overweight) when the patient also has other weight-related conditions such as high blood pressure, high cholesterol or type 2 diabetes


Belviq side effects - Cancer Risk

A clinical study with 12,000 people using the diet pill Belviq  showed an increased risk of cancer including:

  • Pancreatic cancer
  • Colorectal cancer
  • Lung cancer
  • Other cancers

FDA Removes Belviq from US market

On January 14, 2020, the FDA issued a public alert about a clinical trial with Belviq and Belviq XR (lorcaserin). In the 5-year trial, patients showed a possible increase risk of cancer in those taking the weight loss drug. The FDA said it would continue to evaluate the results and would communicate its final conclusion when it completed its review. On February 13, 2020, the FDA asked Eisai, the manufacturer of Belviq and Belviq XR (lorcaserin), to voluntarily withdraw the diet pill from the U.S. market because the clinical trials showed an increased rick of cancer. When the FDA originally approved lorcaserin in 2012, it required Eisai to conduct a clinical trial to evaluate the risk of cardiovascular problems. Instead of showing cardiovascular problems, the clinical trial showed an increased risk of different type of cancers including pancreatic, colorectal, and lung. The results showed more patients taking lorcaserin or Belviq were diagnosed with cancer than those on the placebo. The increase in rate was one additional cancer diagnosis per 470 patients. The study noted the increase in cancer using Belviq came after the patients had used the diet pill for more than a year.

The FDA said, “We are taking this action because we believe that the risks of lorcaserin outweigh its benefits based on our completed review of results from a randomized clinical trial assessing safety.”

The FDA told doctors to stop prescribing the weight loss drug, contact their patients and tell them to stop taking it. FDA offered instructions for disposing of the drug safely.

Belviq FAQ

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.
