The Key Difference
Zepbound uses tirzepatide while Wegovy uses semaglutide. A 2025 trial found greater weight reduction with tirzepatide over the study period, but that does not automatically mean Zepbound is right for every patient. Cost, access, and tolerance all matter.
Cost and Access in 2026
In 2026, Zepbound self-pay pricing became more structured through Lilly's public programs, while Wegovy still relies heavily on insurance and NovoCare savings pathways. Affordability depends on your insurance fit, brand preference, and access stability.
