If you are researching prescription treatments for weight management, you have likely come across the comparison of Wegovy vs Mounjaro. Both medications are injectable treatments designed to support weight loss when combined with healthier eating habits and increased physical activity. Our team at Fishguard Pharmacy often advises patients who are looking for clear and balanced information to determine which treatment best suits their needs.
Although Wegovy and Mounjaro are both used to support weight reduction, they are not identical. They contain different active ingredients, act on the body in slightly different ways and may be prescribed depending on individual health history and eligibility criteria. Understanding these differences is an important first step before starting treatment.
What is Wegovy?
Wegovy contains the active ingredient semaglutide, a medication that mimics a naturally occurring hormone called GLP-1. This hormone plays a key role in regulating appetite and food intake. By activating GLP-1 receptors, Wegovy helps signal to the brain that you feel fuller, which can reduce hunger and limit portion sizes over time.
Wegovy is typically prescribed for adults living with obesity, or for those who are overweight and have weight-related conditions such as high blood pressure or type 2 diabetes. It is administered as a once-weekly injection and the dose is gradually increased over several weeks to minimise side effects and allow the body to adjust.
- Contains semaglutide
- Mimics the GLP-1 hormone
- Reduces appetite and food cravings
- Given as a weekly injection
Treatment with Wegovy is always part of a broader weight management plan. Unsure if this treatment suits your needs? Call us to arrange an appointment and obtain personalised advice.
What is Mounjaro?
Mounjaro contains tirzepatide, which works slightly differently from semaglutide. It targets two hormone pathways in the body, GLP-1 and GIP. By activating both receptors, Mounjaro may enhance appetite control and support blood sugar regulation. This dual action has generated significant interest in the context of weight management.
Like Wegovy, Mounjaro is administered once weekly via injection and follows a gradual dose escalation schedule. It is prescribed following a thorough medical assessment to ensure suitability and safety. As with any prescription medication, it should be used alongside healthy lifestyle changes rather than as a standalone solution.
- Contains tirzepatide
- Targets both GLP-1 and GIP receptors
- Supports appetite control and metabolic regulation
- Requires medical supervision

Wegovy vs Mounjaro: The Major Differences
When comparing Wegovy vs Mounjaro, the primary difference lies in how each medication interacts with hormones that influence appetite and metabolism. While both are weekly injections and both aim to support weight reduction, their mechanisms of action are not the same.
| Feature | Wegovy | Mounjaro |
|---|---|---|
| Active Ingredient | Semaglutide | Tirzepatide |
| Hormone Targets | GLP-1 only | GLP-1 and GIP |
| Dosing | Once weekly injection | Once weekly injection |
| Primary Use | Weight management | Weight management and blood sugar support |
Clinical studies suggest both treatments can lead to meaningful weight loss in eligible individuals. However, results vary from person to person. Factors such as starting weight, lifestyle habits and adherence to the dosing schedule all influence outcomes.
Side Effects of Wegovy and Mounjaro
As with all prescription medications, both Wegovy and Mounjaro can cause side effects. The most common side effects are related to the digestive system, particularly during the early stages of treatment or when the dose is increased.
- Nausea
- Vomiting
- Diarrhoea or constipation
- Reduced appetite
These effects are often temporary and tend to settle as the body adjusts. Ongoing monitoring is important to ensure the medication remains safe and appropriate. A full medical review helps identify any potential contraindications before treatment begins.
Which Weight Loss Treatment May Be More Suitable?
The choice between Wegovy vs Mounjaro should always be based on individual clinical assessment rather than online comparison alone. Your BMI, medical history, current medications and long-term weight management goals all play a role in determining suitability.
