Why do 50-75% of people stop taking GLP-1 drugs within a year?

JAMA opinion piece by Northwestern Medicine cardiologist calls out high discontinuation rate

• A 2023 survey found that the number of U.S. adults interested in using GLP-1 RAs to lose weight dropped from 45% to 14% when they learned they could regain the weight after discontinuing the medication

CHICAGO --- The use of diabetes and weight-loss medications like Ozempic or Wegovy - called GLP-1 drugs - has exploded in recent years, with 12% of U.S. adults having used one despite the high cost, according to a June 2024 poll.

What's less talked about is that 50-75% of people who start taking these drugs stop using them within a year.

Northwestern Medicine cardiologist Dr. Sadiya Khan wants to figure out why, what the harms may be of stopping therapy prematurely, and how to help patients continue their therapy.

"The staggeringly high discontinuation rates of GLP-1 RA should raise alarms for clinicians, policy makers, and public health experts," said Khan, associate professor of medicine (cardiology) and preventive medicine (epidemiology) at Northwestern University Feinberg School of Medicine and a Northwestern Medicine physician.

In a new JAMA Viewpoint opinion piece that will publish Nov. 13, Khan and others call for more research to understand the causes of this discontinuation and the development of clinical and policy interventions to support long-term use.

"Newer, high-potency GLP-1 RAs have revolutionized the therapeutic landscape for patients living with overweight, obesity or diabetes," Khan said. "In addition to the highly publicized weight benefits, these drugs, like semaglutide, have given the magnitude of benefit with a 20-25% reduction in cardiovascular disease events regardless of weight loss achieved."

Media interested in speaking to Dr. Khan should contact Kristin Samuelson.

In the piece titled, "Discontinuation of Glucagon-Like Peptide-1 Receptor Agonists," the Viewpoint authors reference a survey published in 2023, which found that while 45% of U.S. adults were interested in the use of these drugs for weight management, this number declined to 14% when they were informed about gaining the weight back after discontinuing therapy.

Dr. Khan can speak to media about:

• Possible underlying reasons people discontinue taking these drugs, such as cost, time-limited insurance approvals, supply issues, side effects, lack of weight response
• Strategies to improve persistence that prioritize equitable access, lowering medication pricing and out-of-pocket costs, and counseling patients on potential for transient side effects
• Concerns that inequitable uptake of these drugs may exacerbate health disparities
