Weight Loss Efficacy
Clinical trials show Mounjaro is significantly more effective. Patients on Mounjaro lost nearly three times as much weight on average compared to those on Saxenda (22.5% vs 8%).
Cost Considerations
Saxenda often has a lower starting price per pen, but because it is a daily injection, you may go through pens faster depending on your dose. Mounjaro's weekly dosing can sometimes offer better value for money when considering the total monthly cost and effectiveness.
