Wegovy or Mounjaro – Quick Answer
The short answer is:
- Wegovy contains semaglutide and is approved specifically for chronic weight management in eligible adults and certain adolescents.
- Mounjaro contains tirzepatide and was first approved for type 2 diabetes. In some countries, tirzepatide is also approved specifically for weight management under different regulatory approvals.
Many clinical studies have shown that tirzepatide (Mounjaro) often leads to greater average weight loss than semaglutide (Wegovy). However, this does not mean it is automatically the better choice for everyone.
The best medication depends on factors such as:
- Your medical history
- Whether you have diabetes
- Weight loss goals
- Side effects
- Cost and insurance coverage
- Your doctor’s recommendation
