Ozempic, Wegovy, and Mounjaro are three of the most talked-about medications in weight loss and diabetes care today. They all work by mimicking gut hormones, but they’re not the same drug. Each one has a different purpose, dosage, and active ingredient.
Here’s a clear breakdown of how they compare.
1. Ozempic
- Active ingredient: Semaglutide
- Main use: Type 2 diabetes
- Also used for: Off-label weight loss
- FDA approval: Approved for diabetes
- How it works: Mimics GLP-1 hormone to lower blood sugar and reduce appetite
- Dose: Starts low and increases weekly, usually up to 2 mg per week
- Brand focus: Blood sugar control with weight loss as a secondary benefit
2. Wegovy
- Active ingredient: Semaglutide (same as Ozempic, but higher dose)
- Main use: Weight loss and obesity management
- FDA approval: Approved for chronic weight management
- How it works: Same GLP-1 pathway as Ozempic, but at a higher dosage specifically for weight loss
- Dose: Typically titrated up to 2.4 mg per week
- Brand focus: Specifically designed for people with obesity or overweight conditions
3. Mounjaro
- Active ingredient: Tirzepatide
- Main use: Type 2 diabetes, with strong weight loss effects
- Also used for: Off-label weight loss (FDA approval for obesity expected or pending)
- How it works: Dual action drug that mimics both GLP-1 and GIP (another gut hormone), leading to more appetite suppression and fat loss
- Dose: Up to 15 mg weekly
- Brand focus: The most aggressive results in both weight loss and blood sugar control so far
Key Differences
- Ingredient: Ozempic and Wegovy use semaglutide. Mounjaro uses tirzepatide, which targets two hormones instead of one.
- Approved Use: Ozempic and Mounjaro are for diabetes. Wegovy is for weight loss.
- Weight Loss Potency: Mounjaro has shown the strongest weight loss results in clinical trials.
- Cost and Insurance: Coverage varies. Wegovy and Mounjaro can be harder to get approved for weight loss alone.
- Side Effects: All three can cause nausea, bloating, fatigue, or constipation, especially early on.
Which One Is Right for You?
- Choose Ozempic if you have type 2 diabetes and want steady blood sugar control with moderate weight loss.
- Choose Wegovy if your goal is weight loss without diabetes and you qualify for obesity treatment.
- Consider Mounjaro if your doctor recommends a stronger option and you are eligible under diabetes or weight loss guidelines.
Bottom Line
Ozempic, Wegovy, and Mounjaro all work through similar pathways but serve different purposes. Understanding the differences can help you and your doctor choose the right treatment for your health goals.
