Belviq Lawsuit Attorneys

Am I entitled to compensation after taking Belviq?

The US Food and Drug Administration (FDA) warns that the weight-loss drug lorcaserin, marketed under the brand names Belviq and Belviq XR, poses a "potential risk of cancer [that] outweighs the benefits" of its use.

Research indicates that manufacturer Eisai, Inc. may have been aware of an increased instance of cancerous tumors in rats during the pre-market testing phase.

If you took Belviq and have subsequently been diagnosed with cancer,contact us today. Together, we’ll find out if Eisai owes you compensation.

What is Belviq?

Belviq and Belviq XR are the brand names of a drug manufactured by Eisai, Inc. called lorcaserin.

Marketed as a weight-loss drug, lorcaserin alters the user’s brain chemistry – specifically, the serotonin receptor 5-HT2C located in the hypothalamus – to reduce appetite.

Lorcaserin was initially approved by the FDA in 2012 for use as a weight-loss aid to be prescribed in conjunction with calorie reduction and increased physical exercise.

Eligible patients included adults with either (i) a body mass index of 30kg/m2 or greater, which is considered obese, or (ii) a body mass index of 27kg/m2 or greater alongside other weight conditions including type 2 diabetes, high cholesterol, or high blood pressure.

What are the side effects?

Because it manipulates serotonin reuptake, patients were advised not to take Belviq or Belviq XR with other medications that effect that neurochemical system. This may include antidepressants and serotonin reuptake inhibitors. This is due to possible drug interaction and an increased risk of serotonin syndrome. Severe cases of serotonin syndrome can be life-threatening.

Patients were also warned that the drug could lead to cognitive impairment, such as memory loss or confusion, and psychiatric disorders. Any unexpected changes in mood, particularly suicidal thoughts or behaviors, were listed as reasons to discontinue use.

Additional common side effects included nausea, diarrhea, headache, dizziness, fatigue, dry mouth, and constipation.

Why was Belviq taken off the market?

After analyzing data from a five-year study of 12,000 participants, the FDA has concluded that the drug poses an unacceptable risk of cancer.

On February 13, 2020, the FDA advised patients to stop taking Belviq and Belviq XR immediately, and asked Eisai to voluntarily withdraw the drug from the market.

What has Eisai done?

Eisai has voluntarily withdrawn Belviq and Belviq XR from the market. This does not mean, however, that they are not responsible for marketing and distributing a potentially cancer-causing substance.

Meanwhile, the company continues to argue that the FDA’s interpretation of the data from the five-year safety study is false.
