What’s the difference between Mounjaro and Zepbound?

Mounjaro and Zepbound contain the exact same active ingredient, tirzepatide, and are both manufactured by Eli Lilly. The only differences between them are their brand names and their specific FDA-approved uses. 
Feature  Mounjaro Zepbound
Active Ingredient Tirzepatide Tirzepatide
FDA-Approved Use Type 2 diabetes management (along with diet and exercise) Chronic weight management and obstructive sleep apnea in adults with obesity or overweight with a weight-related condition
Mechanism Targets both GIP and GLP-1 hormone receptors to lower blood sugar and reduce appetite Same dual GIP/GLP-1 mechanism to reduce appetite and promote weight loss
Dosing & Admin. Once-weekly subcutaneous injection, same six dosage strengths Once-weekly subcutaneous injection, same six dosage strengths
Insurance More likely to be covered by insurance for a type 2 diabetes diagnosis Coverage is more variable; depends on the specific plan and diagnosis (e.g., often excluded for weight loss, but may be covered for sleep apnea)
Cost List price is slightly different, but both are typically over $1,000/month without insurance List price is slightly different, but both are typically over $1,000/month without insurance; lower-cost vials may be available
In essence, Eli Lilly uses two different brand names for the same drug to target different medical conditions for regulatory and insurance purposes. A healthcare professional will determine which prescription is appropriate based on your health condition, medical history, and insurance coverage. 

 

They are exactly the same medicine containing the same active ingredient (tirzepatide) and work in exactly the same way. The difference is the name: Zepbound is the US name for the weight loss management medicine, whereas in the UK it’s licensed under the name Mounjaro. Zepbound is not licensed in the UK.
