Frequently Asked Questions
What is the difference between Mounjaro and Zepbound?
Mounjaro and Zepbound both contain tirzepatide — the same active ingredient — made by the same manufacturer (Eli Lilly). Mounjaro is FDA-approved for type 2 diabetes. Zepbound is FDA-approved for chronic weight management. The drugs are otherwise essentially identical in mechanism, dosing, and side effects.
Can Mounjaro be used for weight loss?
Mounjaro is sometimes prescribed off-label for weight loss, though it is FDA-approved for type 2 diabetes. When the goal is weight management in patients without diabetes, Zepbound is typically the on-label choice. However, off-label prescribing of Mounjaro for weight loss is legal and practiced by many providers.
Is Zepbound more effective than Mounjaro for weight loss?
Because both contain tirzepatide at identical doses, their clinical effect on weight loss is effectively the same. Zepbound was simply the approval Eli Lilly sought specifically for the weight management indication, using the same SURMOUNT trial data that showed 15–22% body weight reduction.
How much do Mounjaro and Zepbound cost?
Both Mounjaro and Zepbound have list prices of approximately $1,000–$1,500 per month without insurance, depending on the dose. Compounded tirzepatide is available at significantly lower cost through licensed compounding pharmacies and requires a prescription.
