- These effects can help support meaningful weight loss when combined with healthy lifestyle changes.

Frequently Asked Questions
How long does it take for Wegovy to start working?
Many people notice reduced appetite within the first few weeks of treatment. Weight loss is usually gradual and becomes more noticeable as the dose is increased.
Why am I not losing weight on Wegovy?
Weight loss varies between individuals. Factors including dose, diet, physical activity, medical conditions and other medications can all affect results. Weight loss may become more noticeable once higher maintenance doses are reached.
Can I switch from Mounjaro to Wegovy?
Some people may switch treatments following review by their prescriber. The two medicines use different active ingredients and dosing schedules, so any switch should be supervised by the person providing your prescriptions.
