# **What Is Zepbound?**

**Zepbound** (tirzepatide) received FDA approval in 2023 **specifically for chronic weight management** in adults with:

-   A BMI ≥ 30
    
-   OR a BMI ≥ 27 with at least one weight-related condition
    

Zepbound works by activating **GLP-1 and GIP receptors**, which regulate hunger, fullness, digestion, and blood sugar. Combined activation leads to:

-   Reduced appetite
    
-   Slower gastric emptying
    
-   Improved insulin sensitivity
    
-   More stable glucose levels
    
-   Greater weight loss potential than GLP-1-only drugs like Wegovy or Ozempic
    

Because Zepbound is approved for weight loss, most insurance plans categorize it differently from diabetes drugs—and some may cover it more consistently depending on the patient’s profile.

# **What Is Mounjaro?**

**Mounjaro** (tirzepatide) was approved in 2022 as a treatment for **type 2 diabetes**, helping patients:

-   Improve A1C
    
-   Enhance insulin sensitivity
    
-   Reduce blood sugar variability
    

Although not initially approved for weight management, **Mounjaro leads to substantial weight loss** as a secondary benefit, which sparked widespread off-label interest.

As of today:

-   **Mounjaro is FDA-approved for diabetes management**
    
-   **Zepbound is FDA-approved for weight loss**
    

This is one of the most important distinctions when comparing **Zepbound vs Mounjaro**.

### ✔ Branding and labeling

Each drug has its own dosage guidance, supported studies, and approved use cases.

### ✔ Insurance coverage
