With several options now available, patients often ask how Saxenda vs Ozempic compares to Wegovy and Mounjaro, and which option may be best suited to their goals.

How These Weight Loss Injections Work
All four medications work by influencing appetite regulation and blood sugar control, helping patients feel fuller for longer and reduce calorie intake. However, there are important differences in how they are used and the results they may offer.
• Saxenda contains liraglutide and is injected daily
• Ozempic and Wegovy contain semaglutide and are injected weekly
• Mounjaro contains tirzepatide and targets two appetite-related hormones instead of one
These differences can affect weight loss outcomes, convenience, and suitability depending on individual health needs.
Saxenda vs Ozempic vs Wegovy: Understanding the Key Differences
Saxenda was one of the first injectable weight loss medications available privately in the UK. It remains an option for some patients but is generally associated with more modest weight loss results compared to newer treatments.
Ozempic and Wegovy are fundamentally the same medication, both containing semaglutide. The main difference lies in licensing and use:
• Wegovy is licensed specifically for weight loss and is commonly prescribed by private clinics in the UK
• Ozempic is licensed for type 2 diabetes and is primarily used by the NHS in the UK
• In the US, Ozempic is more commonly prescribed for weight loss
Because Wegovy is approved for obesity management, it is usually the preferred choice for private weight loss treatment in the UK.

Where Mounjaro Fits In
Mounjaro is the newest option and has gained attention for delivering some of the most significant weight loss results seen in clinical studies. By targeting both GLP-1 and GIP hormones, it offers enhanced appetite suppression and improved metabolic response.
Many patients choosing a private weight loss clinic in Chelsea now ask specifically about Mounjaro due to its effectiveness and weekly dosing schedule. Book an appointment with our clinical team to find out if Mounjaro is suitable for you.

| Medication | Active Ingredient | Injection Frequency | Average Weight Loss | UK Use |

Choosing the Right Option for You
The best treatment depends on more than just potential weight loss results. A thorough clinical assessment is essential to ensure safety, suitability, and long-term success.
Patients may consider:
• Current BMI and weight-related health conditions
• Previous experience with weight loss medications
• Preference for daily or weekly injections
• Desired level of clinical support and monitoring
Why Many Patients Are Choosing Mounjaro
Many patients are choosing Mounjaro due to its strong clinical results and the way it targets appetite from two different hormonal pathways rather than one. By acting on both GLP-1 and GIP receptors, Mounjaro can offer greater appetite suppression, improved blood sugar control, and more significant weight loss outcomes compared to earlier injectable treatments. The convenience of weekly dosing, combined with structured clinical support from a trusted provider, has made it a popular choice for those seeking effective, medically supervised weight management.

A New Wegovy Pill on the Horizon
There is growing interest in a new Wegovy weight loss pill that may become available to UK patients in the near future. This oral version of semaglutide is still under development and undergoing regulatory review, but it may appeal to individuals who prefer not to use injections. While this option is not yet available through private clinics in the UK, its potential arrival highlights how quickly weight loss treatments are evolving, reinforcing the importance of choosing a clinic that stays informed and adapts treatment plans as new options emerge.
Why Provider Choice Matters

Helping You Choose Between Saxenda vs Ozempic vs Wegovy vs Mounjaro
While Saxenda, Ozempic, Wegovy, and Mounjaro all support weight loss, they are not interchangeable. Wegovy and Ozempic may be chemically identical, but their approved uses differ in the UK, while Mounjaro represents the most advanced option currently available.
Choosing the right medication and the right clinic can make a significant difference to both results and long-term health outcomes.
