Adherence to Wegovy far outpaces older weight loss drugs: Cleveland Clinic study

Patients taking Novo Nordisk's weight loss drug Wegovy in 2021 and 2022 were three times more likely to continue taking the medication a year later compared to older weight loss therapies, according to a study published Dec. 6 in Obesity

Researchers from Cleveland Clinic evaluated about 1,000 EHRs between January 2015 and July 2023 among patients who were taking anti-obesity medications. The EHRs were collected from a large health system in Ohio and Florida. 

The weight loss drug with the highest adherence was Wegovy (semaglutide), with 40% of Wegovy patients still filling prescriptions after a year. In comparison, the adherence of orlistat, liraglutide, naltrexone-bupropion and phentermine-topiramate after 12 months ranged between 0% and 19%. 

The findings show another aspect to the increased popularity of glucagon-like peptide-1 receptor agonists like Wegovy. In October, a first-of-its-kind study from a California hospital system found an "exponential" increase in patients using Wegovy, Mounjaro and other GLP-1s.
