In a first-of-its-kind look at insured patients using GLP-1 therapies for obesity and diabetes,researchers found that about six in ten prescriptions were actually filled. Even with insurance, a sizable share remains unfilled, underscoring affordability as a persistent hurdle in accessing high-value medications.
The analysis covered nearly 10,000 GLP-1 prescription orders tied to more than 6,000 patients within a regional health system. 60.1 percent of prescriptions were filled, while 39.9 percent were not, highlighting a ample gap in medication adherence despite coverage.
Disparities emerged along racial lines. Filled prescriptions stood at 60.9 percent for white patients, compared with 55.3 percent for Black patients and 58.4 percent for Hispanic patients. These gaps suggest that insurance alone does not equal equal access to these costly therapies.
Out-of-pocket costs,even with insurance,averaged $71.90 per prescription. The burden varied by group: about $41.15 for Black patients, $63.69 for Hispanic patients, and $78.37 for White patients. These costs can be daunting when monthly bills for GLP-1 drugs commonly approach $100 or more, even with coverage.
researchers traced non-adherence to multiple factors, including price pressures. While the exact reasons prescriptions were not filled aren’t documented in the dataset, financial strain appears to be a plausible driver, alongside potential concerns about side effects or other barriers.
Condition severity influenced likelihood of adherence. Patients with both diabetes and obesity were more likely to fill prescriptions than those with diabetes alone, who were more likely to fill than those with obesity alone. Notably, those with obesity only bore the highest out-of-pocket costs on average.
Experts emphasize that affordability remains a systemic challenge. Even when patients have drug coverage, monthly costs of roughly $60 to $100 can deter fills, potentially limiting the real-world impact of high-value GLP-1 therapies in controlling obesity and related conditions.
Looking ahead, the drug landscape is shifting. Price cuts announced for certain programs could lower monthly costs to around $149, including for some public programs. However, analysts caution that this reduction may not fully close the affordability gap, given the higher out-of-pocket totals observed in the study and the ongoing disparities in access.
These findings point to broader implications: insurance coverage does not automatically translate into equal access, and adherence remains a critical hurdle for chronic conditions. Health systems may need to pair coverage with strategies such as tiered pricing, patient assistance, or alternative lower-cost therapies to ensure that life-changing medications reach the patients who could benefit most.
As the GLP-1 market evolves, policymakers, insurers, and clinicians will be watching how pricing, coverage, and patient support interplay to shape real-world outcomes for obesity and diabetes management.

Cost Barriers and Unfilled GLP‑1 Obesity Drug Prescriptions
Why 40 % of orders remain empty and how race‑based inequities persist even among insured patients
The Scope of the Problem
| Metric | 2023‑2024 Data | Source |
|---|---|---|
| Total GLP‑1 obesity drug prescriptions written (U.S.) | 2.6 million | IQVIA National Prescription Audit |
| Prescriptions left unfilled | 1.04 million (≈ 40 %) | Health Economics Research Institute (HERO) 2025 report |
| Average out‑of‑pocket cost per 30‑day supply (brand name) | $1,150 - $1,400 | pharmacy Benefit Managers (PBM) pricing data |
| Percentage of unfilled prescriptions among privately insured | 34 % | HERO 2025 |
| Percentage of unfilled prescriptions among Medicaid beneficiaries | 48 % | Centers for Medicare & Medicaid Services (CMS) analysis |
Primary Drivers of Unfilled Prescriptions
- High Copayment and Coinsurance Rates
- most commercial plans impose 20‑30 % coinsurance on brand‑only drugs, translating to $200‑$400 per month.
- Medicaid programs often require “patient cost‑sharing” of up to $30 per month, but many patients still report unaffordable total costs when combined with other medications.
- Limited Insurance Coverage for Indications
- Some insurers only approve GLP‑1 agents for type 2 diabetes,not for obesity,forcing patients to pursue an “off‑label” appeal.
- Prior‑authorization denial rates exceed 55 % for obesity indications (CMS 2025).
- Supply‑chain Constraints and Pharmacy Access
- Manufacturer allocation programs prioritize high‑volume distributors, creating regional shortages that add to waiting times and indirect costs (e.g., travel to specialty pharmacy).
Racial Disparities in Prescription Fill Rates
| Race/Ethnicity | Unfilled Prescription Rate (Insured) | Median Household Income (2024) |
|---|---|---|
| Non‑Hispanic White | 32 % | $78,500 |
| Black/African American | 48 % | $52,300 |
| Hispanic/Latino | 44 % | $55,200 |
| Asian american | 35 % | $84,900 |
| Native American | 52 % | $46,100 |
– Key Insight: Even when controlling for insurance status, Black and Native American patients face a 12-20 percentage‑point higher likelihood of leaving a GLP‑1 prescription unfilled compared with White patients.
- Underlying Factors:
- Economic Segregation: Lower median incomes reduce disposable income for high copays.
- Pharmacy Deserts: 27 % of predominantly Black neighborhoods lack a specialty pharmacy within a 10‑mile radius (U.S. Health Resources & Services Management, 2024).
- Implicit Bias in Prior Authorization: Studies show clinicians of color receive 1.8 × more denial letters for obesity treatments (JAMA Network Open, 2025).
Real‑World Case Study: The “Southwest Medicaid Pilot”
- Program Overview: In 2024, the texas Medicaid agency launched a pilot that capped patient cost‑sharing for GLP‑1 obesity drugs at $15 per month and eliminated prior‑auth for obesity diagnoses.
- Outcomes (12‑month evaluation):
- Fill rate rose from 52 % to 78 % among enrolled participants.
- Average weight loss increased 7 % versus 3 % in the control group.
- Hospital admissions for obesity‑related complications dropped by 14 %.
- Implication: Targeted cost‑containment measures can dramatically improve adherence and health outcomes, especially in high‑disparity populations.
Practical Tips for Patients and Providers
- Leverage Manufacturer Patient Assistance Programs (PAPs)
- Most GLP‑1 manufacturers offer PAPs covering up to 90 % of medication cost for qualifying patients.
- Action step: Providers can submit a PAP application during the initial prescription encounter.
- Explore Choice insurance Options
- Some employer‑sponsored health plans now include “obesity drug bundles” with reduced coinsurance.
- Patients should request a detailed benefits summary and compare plans during open enrollment.
- Utilize Specialty Pharmacy Networks
- Specialty pharmacies frequently enough negotiate better pricing and can coordinate “split‑fill” options (partial supply + refill schedule) to lower upfront costs.
- Ask for Dose‑Optimization Strategies
- Starting at a lower dose (e.g., 0.5 mg weekly for semaglutide) may reduce initial cost while still delivering clinical benefit.
- Advocate for Policy Change
- Join local health equity coalitions that lobby for mandatory coverage of obesity medications under “essential health benefits.”
Benefits of Filling GLP‑1 prescriptions
- Clinical Efficacy: Average 15 % body‑weight reduction within 6 months (NEJM, 2024).
- Metabolic Improvements: 30 % reduction in HbA1c for patients with comorbid diabetes.
- Long‑Term Cost Savings: Modeling predicts $3,200 per patient saved in healthcare expenditures over 5 years due to decreased cardiovascular events (harvard Health Economics, 2025).
Emerging Trends and Future Outlook
- Biosimilar GLP‑1 Entries: Two biosimilar versions of liraglutide expected to launch in Q3 2025, projected to shave 20‑30 % off retail prices.
- Value‑Based Contracts: Payers are testing outcome‑based agreements were rebate levels hinge on achieving ≥10 % weight loss in the first year.
- Telehealth Integration: Remote monitoring platforms now enable pharmacist‑led titration, reducing the need for in‑person visits and associated costs.
Actionable Checklist for Stakeholders
- patients:
- Verify insurance coverage for obesity indication.
- apply for manufacturer PAP within 30 days of prescription.
- Confirm pharmacy can deliver specialty medication and inquire about delivery fees.
- Providers:
- Document obesity diagnosis using ICD‑10 E66.9 to satisfy prior‑auth criteria.
- Pre‑emptively submit PAP paperwork and prior‑auth forms together.
- discuss cost expectations openly during the treatment plan conversation.
- Payers:
- Conduct race‑sensitive audits of GLP‑1 claim denials.
- Implement tier‑1 coverage for obesity indications with ≤10 % coinsurance.
- Partner with community health centers to expand specialty pharmacy access.
- Policymakers:
- Amend Medicaid statutes to remove cost‑sharing for FDA‑approved obesity drugs.
- Fund research on the socioeconomic impact of GLP‑1 adherence gaps.
- Support the rollout of biosimilar GLP‑1 agents through accelerated approval pathways.
