Faqs
If you are currently taking Saxenda (or previously have taken Saxenda) then follow the following guidance:
- If you are taking 3.0mg Saxenda once-daily then you can switch to 0.5mg Wegovy.
Wegovy and Saxenda are from the same class of medicines (GLP-1) however they are different molecules. Starting from 0.5mg will reduce the chances of side effects such as nausea so it is the safer and appropriate option. After 4 weeks on 0.5mg you can increase this to 1.0mg and then to the higher doses accordingly.
- If you are taking a lower dose than 3.0mg Saxenda then you should start on 0.25mg Wegovy.
- If you have been on Saxenda previously but had a long gap in treatment then you should start on 0.25mg Wegovy.

Where wegovy is a once-weekly injection, Saxenda is a once-daily injection, also licensed for weight loss which has been available since 2017. It works in a very similar way to Wegovy and is manufactured by the same company. The active ingredient of Saxenda is liraglutide (also a GLP-1 – a synthetic version of the naturally occurring hormone GLP-1).
Ozempic and Wegovy contain exactly the same active ingredient (Semaglutide). Ozempic is licensed for the treatment of type-2 diabetes whereas Wegovy is specifically licensed for weight management (including weight loss and weight maintenance).
Ozempic is available in 3 doses (0.25mg, 0.5mg and 1.0mg) whereas Wegovy is available in 5 doses (0.25mg, 0.5mg, 1.0mg, 1.7mg and 2.4mg).
Semaglutide is the chemical name and active ingredient which is contained in Wegovy. Wegovy is therefore one of the brand names of Semaglutide which is licensed for licensed for weight management.
Ozempic and Rybelsus (medicines licensed for the treatment of type-2 diabetes) also contain Semaglutide.
A 86-week clinical trial by the manufactures showed that patients using Wegovy achieved an average weight loss of 14.9% (compared to 2.4% in the placebo group).
Of those:
- Almost 84% achieved weight loss of less equal to or greater than 5%
- Over 66% achieved weight loss of equal to or great than 10%
- Almost 50% achieved weight loss of over 15%
- Over 30% of patients lost more than 20% of their starting body weight.
Alongside taking wegovy, it is important to maintain a healthy diet and increase in physical activity.Whereas the trials have shown this to be very effective in the majority of patients taking it, like any medication, it is not guaranteed to work for you. You may either not tolerate it (have severe side effects) or not respond to it and find that it does not work for you.
