At Live Well Weight Loss, many patients have started their journey with Mounjaro® (tirzepatide). However, due to changes in supply and pricing, some people may now be considering or needing to switch to Wegovy® (semaglutide).

We want to reassure you that any switch will be handled carefully and on a case-by-case basis, with your safety and results as our top priority.


Why Might You Switch?

Mounjaro is an effective treatment for weight loss, but with current supply challenges, some patients may find it difficult to continue. Wegovy is now more widely available in the UK and provides another clinically proven option.


Key Differences Between Mounjaro and Wegovy

Mounjaro (tirzepatide): Works on two appetite and blood sugar pathways (GLP-1 and GIP).

Wegovy (semaglutide): Works on a single pathway (GLP-1), but still has strong evidence for long-term weight loss.

Both are weekly injections designed to support sustainable weight loss.


What to Expect if You Switch

If you are moving from Mounjaro to Wegovy, we will:

Review your medical history and current progress

Recommend the most appropriate starting dose of Wegovy

Monitor your response closely and adjust treatment as needed

This process will always be tailored to your individual needs.


Wegovy Pricing at Live Well Weight Loss

We believe in keeping pricing simple and transparent:

0.25 mg – £109

0.5 mg – £109

1 mg – £109
