FAQ
What is the difference between Ozempic, Mounjaro, Trulicity, and Victoza?
Ozempic (semaglutide), Mounjaro (tirzepatide), Trulicity (dulaglutide), Victoza (liraglutide) are GLP-1 medications used for weight management or type 2 diabetes. Key differences: Ozempic is FDA-approved; Mounjaro is FDA-approved; Trulicity is FDA-approved; Victoza is FDA-approved.
Which is most effective for weight loss among the four?
Effectiveness varies by individual. In clinical trials, tirzepatide-based drugs (Mounjaro, Zepbound) produced ~20-22% average body-weight loss vs ~13-15% for semaglutide-based (Ozempic, Wegovy). Daily liraglutide (Saxenda, Victoza) produced about 6-8% on average. Discuss with your prescriber.
Which is cheapest?
Cash retail price: Ozempic $968/mo · Trulicity $987/mo · Victoza $1023/mo · Mounjaro $1135/mo. Compounded versions through telehealth typically run 50-80% less when legally available.
Can I switch between these four medications?
Yes — switching is clinically common, usually driven by side-effect tolerance, weight-loss plateau, insurance coverage changes, or supply issues. Most prescribers restart at the new drug's starting dose rather than dose-matching, because cross-drug equivalence is not 1:1 — particularly when switching between GLP-1-only (semaglutide, liraglutide) and GIP/GLP-1 dual-agonist (tirzepatide).
