Wegovy vs. Mounjaro: Which Weight Loss Injection Is Right for You?
With recent changes in the cost of different weight loss injection medication it has now become more difficult to chose which to start, or even if you should change from one to another.
If you’re exploring weight loss injections to support your health or fertility journey, you’ve likely come across two big names: Wegovy and Mounjaro.
These medications have helped thousands of people lose weight and improve their overall health—but how do they compare, and which one might be best for you?
In this guide, we’ll break down the differences between Wegovy and Mounjaro in simple terms, so you can make an informed decision with your doctor.
What Are Wegovy and Mounjaro?
Both Wegovy and Mounjaro are prescription weight loss medications given as weekly injections. They work by mimicking hormones that help regulate appetite and blood sugar levels.
| Medication | Active Ingredient | How It Works |
| Wegovy | Semaglutide | Mimics GLP-1 hormone to reduce hunger and slow digestion |
| Mounjaro | Tirzepatide | Targets both GLP-1 and GIP hormones for stronger appetite control |
How Much Weight Can You Lose?
Clinical trials show impressive results for both medications:
- Wegovy users lost around 15% of their body weight over 68 weeks.
- Mounjaro users lost up to 20% of their body weight in the same time frame.
That means Mounjaro may offer slightly more weight loss, but individual results vary.
❤️ Health Benefits Beyond Weight Loss
Both medications can improve:
- Blood sugar control
- Blood pressure
- Cholesterol levels
- Fertility – a 10% in body weight has been linked with more than a 60% increase in the chance of natural conception!
However, Wegovy has shown strong heart health benefits, reducing the risk of heart attack and stroke in people with obesity and heart disease.
Side Effects to Know About
Common side effects for both include:
- Nausea
- Diarrhoea

Some people find Mounjaro causes more stomach upset due to its dual hormone action. Starting with a low dose and gradually increasing can help manage side effects.

- Tolerance for side effects
Talk to your specialist, GP or a weight management specialist to find the best fit for your needs.
