How it differs from related products
Mounjaro contains tirzepatide, the same drug as Zepbound. Its approved use is type 2 diabetes, not weight management. A prescriber using a diabetes-approved product to treat weight is using it off-label. This atlas does not advise on that.
| Product | Form | U.S. approved use | Status |
|---|---|---|---|
| Zepbound | Weekly injection | Weight management | FDA-approved for weight management |
| Mounjaro (this page) | Weekly injection | Type 2 diabetes | FDA-approved, but not for obesity |
What it is approved for
Type 2 diabetes. The current label lists the exact approved uses.
A prescriber using a diabetes-approved product to treat weight is using it off-label. This atlas does not advise on that, and its weight-loss figures are not from studies of this product.
How it is taken
Weekly injection. Follow the current label and your prescriber for how to use it.
What the trials found
The weight-loss trial figures in this atlas come from studies of the weight-management products. They are not shown here because they were not studies of Mounjaro's approved use.
