Wegovy was created off the back of the weekly injection treatment for type-2 diabetes: Ozempic. When people with diabetes used Ozempic to help lower their blood sugar, it was found that it had the side effect of reducing their appetite and encouraging weight loss. Because of this, clinicians started prescribing Ozempic to people ‘off-label’ (outside of its license) in order to help them lose weight. As a result, Wegovy has now been formulated as a different version of Ozempic specifically licensed for weight loss. Both treatments contain the same active ingredient, but Wegovy specifically targets weight loss in a way that’s both safer and more effective for you.
The other main difference between Wegovy and Ozempic is the dosage, with Wegovy available in higher strengths than Ozempic (the maximum recommended weekly dose of Ozempic is 1mg, compared with 2.4mg for Wegovy). This means that it should be able to help you lose weight more quickly and effectively than Ozempic.
Saxenda is another similar treatment to Wegovy in that it’s also a licensed injectable treatment for weight loss. But where you only need to use Wegovy once a week, Saxenda needs to be used every day for it to be able to work effectively. Saxenda also uses a different active ingredient (liraglutide) which you might find more or less suitable for you. Although Saxenda has been a licensed treatment for longer, some studies suggest that Wegovy is more effective.
