How are Zepbound, Mounjaro, and compounded tirzepatide different?
Short answer
Zepbound and Mounjaro are FDA-approved brand medicines containing tirzepatide, but they have different approved uses. Compounded tirzepatide is prepared by a licensed pharmacy for one patient and is not FDA-approved. A licensed physician in your state decides which treatment, if any, is appropriate for your health needs.
Zepbound and Mounjaro both contain tirzepatide. Zepbound has FDA-approved uses that include long-term weight management in eligible adults. Mounjaro is approved to help manage blood sugar in people with type 2 diabetes. These brand medicines have specific prescribing instructions and approved labeling.
Compounded tirzepatide is prepared by a licensed pharmacy for one patient and is not FDA-approved. The FDA does not review compounded medications for safety, effectiveness, or quality before they are marketed. Compounding is subject to legal limits and is not a routine substitute for an available approved medicine.
A licensed physician in your state decides whether treatment is appropriate. If compounding is considered, ask why an approved product cannot meet your medical needs. Do not assume a compounded product will come in the same device, concentration, or package as a brand medicine.
Always follow the instructions for the exact product you receive. Ask the pharmacy to explain the label, storage rules, and injection supplies before your first dose. Never transfer dosing instructions from one product to another.
