Dose Comparison Tool
Some patients worry that Wegovy may be less effective because the doses look smaller, but the two medications cannot be directly compared. Wegovy remains highly effective. Importantly, you won’t need to restart your journey. During your assessment, simply answer the questions as usual- you’ll be asked what you are currently taking (Mounjaro) and at what dose, and then whether you'd like to switch to Wegovy. From there, you’ll be guided to the most appropriate dose for you.
What dose of Mounjaro are you currently using?
Simple recommends you use the following Wegovy dose if you switch;
If you experience side effects after switching, please consider using a lower dose to allow your body to acclimatise to the new medication.
What dose of Mounjaro are you currently using?
Simple recommends you use the following Wegovy dose if you switch;
If you experience side effects after switching, please consider using a lower dose to allow your body to acclimatise to the new medication.

† Injection site reactions: Long-term studies found these in 0.3% of Wegovy users and 8.6% of Mounjaro users.
‡ Heart health: Clinical trials show Wegovy can reduce the risk of heart attack, stroke and death from heart disease by up to 20% in people with obesity or who are overweight and have existing heart disease, even if they don’t have diabetes.
