Discontinuation of glucagon-like peptide-1 receptor agonists among US adults: A national survey.
Although many people discontinue glucagon-like peptide-1 receptor agonists (GLP-1 RAs), the reasons for discontinuation are unclear.
To identify self-reported reasons for GLP-1 RA discontinuation among US adults.
Cross-sectional survey of US adults fielded in June 2025 using Ipsos Omnibus and incorporating survey weights calibrated to census benchmarks. We included individuals who initiated a GLP-1 RA between January 2022 and June 2025 and subsequently discontinued therapy. Outcomes included duration of use, self-reported reason(s) for discontinuation, medication source, out-of-pocket payment, and insurance coverage. Descriptive statistics and chi-square tests for statistical significance were used.
Of 7,035 individuals screened, 440 respondents met eligibility criteria and completed the survey. Of these 440 participants, 51.1% were female, 42.3% were aged between 18 and 34 years, and 23.8% reported having type 2 diabetes. More than half of these discontinuers (54.6%) reported discontinuing a GLP-1 RA within 6 months of initiation, and 79.7% reported discontinuation within 12 months of use. Approximately 1 in 7 (14.4%) reported sourcing GLP-1 RAs from a friend or family member, and more than half reported using a copayment coupon (35.4%) or free sample (22.0%). Many respondents (31.3%) reported first filling a prescription without insurance. Approximately 1 in 5 reported sourcing their medicine from a compounding pharmacy (9.8%) or Internet-based (9.1%) source. The most frequently cited reasons for discontinuation were cost (36.1%), side effects (33.3%), no insurance coverage (28.2%), and achieving a weight-loss goal (26.1%). Compared with those without diabetes, respondents with diabetes were significantly more likely to discontinue because of side effects (50.1% vs 28.1%, P = 0.0008). Respondents who reported sourcing their GLP-1 RA from a compounding pharmacy or Internet-based source were significantly more likely to discontinue because they perceived the medication to be ineffective compared with those who obtained their medication from a retail or mail-order pharmacy (17.5% vs 6.6%, P = 0.009). Neither diabetes status nor GLP-1 RA source was significantly associated with early discontinuation (<6 months).
In this national survey, most US adults who stopped GLP-1 RAs did so within 6 months because of cost, adverse effects, lack of coverage, or having achieved a weight loss goal. Differences in coverage, costs, and sourcing are modifiable targets that may decrease high rates of GLP-1 RA discontinuation.
