Prescription Weight Loss Medication Belviq Linked to Increased Cancer Risk

Prescription Weight Loss Medication Belviq Linked to Increased Cancer Risk
Calendar icon May 12, 2021

Beginning in June 2012, Eisai, Inc. sold the prescription weight loss medication Belviq in the United States market. Little recognized in early 2020 as the emerging pandemic captured the world’s attention, the Food and Drug Administration issued a formal safety communication identifying Belviq as a human carcinogen and requested that it be voluntarily withdrawn from the market. The resulting FDA announcement directed that physicians immediately stop prescribing Belviq and direct their patients to discontinue the medication.    

These risks were not new. The FDA had previously refused to approve Belviq, rejecting Eisai’s application in September 2010 due to the cancer risk shown in animal studies and because the product worked poorly. On reapplication, the FDA allowed Belviq for limited patient populations based on body mass index and weight-related conditions.  Less than a year later, however, the European Medicines Agency refused to approve the medication due to the increased occurrence of cancerous tumors in animal studies. The drug’s risks outweigh any possible benefits.  

Notably, Belviq was marketed as a weight loss aid and not a necessary life-preserving medication. Internal studies indicated that the medication performed poorly even for its intended purpose, achieving limited weight loss in high body mass index patients and leading to weight regain with continued use. In addition to its known risks and documented lack of results, insurance frequently failed to cover Belviq and patients paid approximately $300 each month for the medication. 

The FDA found that Belviq patients reported a wide range of cancer types, with pancreatic, colorectal, and lung cancers being the most frequently occurring injuries.  Much like other cancer-causing products – including Zantac (ranitidine), valsartan, talcum powder, Roundup weed killer and asbestos – Belviq presented an unreasonable risk of injury while serving an unneeded purpose when safer alternatives existed.  If you or a loved one has been diagnosed with cancer after using Belviq, the lawyers of Cellino Law would be honored to seek financial justice for your injury.  



Free Case Review




  • Cellino Law was a great company to work with. From the beginning they came out and met with my uncle and myself and assured us that everything would be taken care of from beginning to end our lawyer state and constant contact with us to make sure that everything would go smoothly and it did. I would definitely recommend anybody to go to Cellino Law for whatever help they need. And specifically please ask for the lawyer that we had Mr. Alan Silverstein. He was amazing and his staff was always attentive. Please go with them for your next law needs.


  • Thank you for your help in settling the case of my father's accident. I could always count on you to answer my questions honestly and in terms I could understand. If all lawyers at Cellino Law are like you, I understand why they are an A-1 law firm.


  • We'd like to thank you for all the assistance and time you spent on our case. Your professionalism and honesty will always be appreciated. The staff was always courteous and we were always impressed with your accountability. Your passion and dedication will never be forgotten, nor will you.


  • Thank you for your time, effort, and hard work on my case. I appreciate your expertise and compassion. I never experienced what I went through and I would have been completely lost without you.


  • My experience during the time of negotiations was extremely positive. Josh Sandberg handled my lawsuit with the utmost integrity. He returned all my phone calls in a timely manner and answered all my questions. Josh made things less stressful. I would highly recommend Josh and the entire staff at Cellino Law.


  • This letter is to thank Ms. Diane D’Andrea, assistant to Mr. George Gridelli, Attny for all the hard work, dedication, and attentiveness she showed during the representation of my case. She was always cheerful and ready to help in whatever way she could. All messages left for Mr. Gridelli were always relayed and Mr. Gridelli always promptly returned our calls. She was a very competent assistant. Cellino Law has proven to be a model of what legal representation should be. Throughout the 6 ½ years of this case, I have heard many horror stories from people with “bad lawyer stories.” We consider ourselves to be very lucky to have chosen Cellino Law and will always recommend you to those looking for good, honest representation with a personal touch.
