Plenity – a New Option for Weight Loss

Posted: Jan 30 in Medical Weight Loss News, Weight loss, Weight Loss Medication by

Plenity is an aid for weight management in adults with a body mass index (BMI) of 25 to 40, when combined with a healthy eating and physical activity plan.

Dr. Lazarus and Heather Thomas, PA-C are excited to announce that they have been accepted to the early prescriber program for Plenity. Although Plenity is planning a release this summer (2021), Dr. Lazarus and Heather will each be able to prescribe early for a small number of patients (more information on this soon…)

Plenity is an FDA cleared weight management approach made from naturally derived ingredients including cellulose and citric acid. People take 3 capsules with 16 ounces of water 20-30 minutes before lunch and dinner. The capsules contain a superabsorbent hydrogel which expands in the stomach to 100 times their original weight promoting satiety and fullness. They later pass unabsorbed through normal bowel movements.

In their GLOWS study, ~6 out of 10 people treated with Plenity were responders, achieving 5% weight loss or more (an average weight loss of 10% or ~22 pounds), while 1 in 4 lost 10% or more (an average weight loss of 14% or ~30 pounds).

In this study, the was no difference in overall adverse events (AEs) vs. placebo. The most common AEs were abdominal pain, constipation, flatulence, infrequent bowel movements, abdominal distension, diarrhea, and nausea. 95% were mild or moderate, occurred within the first 3 months, and resolved within 2 weeks.*

So, what do we think? We are excited to be included in the early prescriber program, and to start to provide Plenity for our patients. People who prefer not to be on a medication may prefer Plenity as it is not systemically absorbed. Or, people who have struggled to lose weight and just need a different option may respond nicely. Plenity costs $98 for a 4 week supply, and is only available through a mail order pharmacy. Insurance coverage is not available for Plenity.

For more information, please check out Plenity’s web site here, or schedule a visit with Dr. Lazarus or Heather by calling us at (303) 750-9454. We look forward to hearing from you!

    I have constant heartburn. I live on tums or acid reducer pills to keep my heartburn to a minimum. I do want to try plenity but do not want to add to my current uncomfortableness. Any suggestions would be appreciated.

    • Dr. Lazarus says:

      Hi Dee. In this situation, Plenity would likely not be my first choice. A few considerations – first, you might talk your doctor about your heartburn. They might want to refer you to a gastroenterologist for further testing, and to see if you are receiving the best treatment options. After receiving the best management for your gastrointestinal issues, a weight loss doctor could work with you to discover the best weight loss medication treatment options – whether that be Plenity, or one of the other options. Hope this helps!

  • Julia says:

    What if a person has occasional acid reflux? Will the medication not be prescribed? Also, what specifically about having acid reflux is bad when taking plenity?

    • Dr. Lazarus says:

      It would probably still be reasonable to do a trial of Plenity for Weight Loss. If it made the GERD symptoms a lot worse, Plenity would need to be discontinued – at least that’s my opinion 🙂
