Thinking about switching weight loss treatment? The cost of the Weight Loss Treatment Service varies depending on which medication is prescribed and being prescribed Wegovy may be a more cost-effective option. The table below shows the likely Wegovy dose based on a current Mounjaro dose, subject to a clinical review.

Mounjaro Strength Wegovy equivalent Monthly cost difference*
2.5mg 1mg Save £30
5mg 1.7mg Save £29
7.5mg 2.4mg Save £62
10mg 2.4mg Save £97
12.5mg 2.4mg Save £109
15mg 2.4mg Save £129

If switching is appropriate, we can help you move to the most appropriate Wegovy dose depending on your medical history, current treatment plan and experience with Mounjaro side effects. You won’t need to start again or take any breaks, but ultimately which dose is best for you will be a decision between you and your clinician.
