GLP-1 receptor agonists are the most consequential drug class to emerge in obesity and type-2 diabetes since metformin. The category started with exenatide and liraglutide, broke commercial ceilings with semaglutide (Ozempic, Wegovy) and tirzepatide (Mounjaro, Zepbound), and is now expanding into orals (orforglipron, oral semaglutide), triple agonists (retatrutide), and amylin combinations (cagrisema, eloralintide).
The signal worth tracking has shifted. Weight loss alone is no longer the headline — secondary indications are. SELECT showed a 20% drop in major adverse cardiovascular events for non-diabetic adults with obesity. A Mass General Brigham analysis in JAMA reported 42–58% lower heart-failure hospitalizations in HFpEF. AAN 2026 added migraine, dementia incidence, and Parkinson's signals to the growing list. The Phase 3 EVOKE Alzheimer's trial, by contrast, missed its endpoint.

1 in 8 US Adults Now Taking a GLP-1 Drug
About 1 in 8 US adults now report taking a GLP-1 drug per KFF. Experts caution effects are larger and longer-lasting when combined with lifestyle changes.
GLP-1 Adherence Shows Significant Drop-Off After 1 Year
New data shows GLP-1 adherence drops significantly after the first year, with cost as a major factor. Insurance gaps and lack of mandated weight loss coverage pose barriers.
Compounded GLP-1 Prescriptions Keep Rising Despite FDA Crackdown
Healthcare Brew reports that despite the FDA sending thousands of warning letters since September 2025, compounded semaglutide and tirzepatide prescriptions have increased since the semaglutide shortage ended in February 2025. About 80% of compounded GLP-1 prescriptions now include supplemental ingredients like B vitamins to avoid being classified as exact copies of FDA-approved drugs.
Cleveland Clinic Study: Most Patients Avoid Dramatic Weight Regain After Stopping GLP-1 Drugs
A Cleveland Clinic analysis of 7,938 adults who discontinued semaglutide or tirzepatide found that real-world outcomes are better than clinical trials suggested. Obesity patients regained just 0.5% of body weight on average after one year, and 45% either maintained or continued losing weight by restarting treatment, switching medications, or adopting lifestyle changes.
GLP-1 Lawsuits Surpass 3,500 Pending Cases as Vision Loss Claims Surge
Over 3,546 lawsuits are now consolidated in two federal MDLs — one for gastroparesis and one for NAION vision loss. On March 3, a federal judge appointed lead counsel for the NAION MDL. Studies show semaglutide users face a fourfold increase in NAION risk, with vision loss claims now generating more legal attention than earlier gastroparesis cases.
Medicare to Cover GLP-1 Weight Loss Drugs at $50/Month Starting July 2026
CMS confirmed that Medicare Part D beneficiaries will gain access to Wegovy and Zepbound for weight loss through the Medicare GLP-1 Bridge program starting July 2026 at a $50 monthly copayment, bridging to the full BALANCE Model launching in Medicare Part D in January 2027.
GLP-1 Drugs Reshaping American Eating: Grocery Spending Down 5.3%, Fast Food Down 8%

NeurologyLive Review: GLP-1 Drugs Explored for Parkinson's, MS, and Sleep Disorders
A comprehensive NeurologyLive review examines evidence for repositioning GLP-1 drugs across neurological conditions. Exenatide and lixisenatide show motor benefits in Parkinson's disease, while GLP-1 agonists reduced intracranial pressure and migraine days in idiopathic intracranial hypertension. The semaglutide EVOKE trials in Alzheimer's failed clinically despite modest biomarker improvements.
