switching from saxenda to wegovy

Medically reviewed by


Switching from Saxenda to Wegovy involves informing your healthcare provider and adjusting dosage. Both are GLP-1 receptor agonists, but they work differently. Saxenda boosts ghrelin to control weight, while Wegovy reduces hunger and aids glucose regulation, suitable for type 2 diabetes.

Saxenda shows effects in 1-2 weeks, Wegovy in 6-12 weeks. Saxenda requires daily injections, while Wegovy offers weekly ones. Doses vary; Wegovy from 0.25 mg to 2.4 mg, Saxenda from 0.6 mg to 3 mg. Consult your doctor for personalised advice.

Switching from Saxenda to Wegovy is relatively straightforward; it’s just a case of informing your healthcare provider – who should be able to advise you accordingly – and then making sure you are taking the correct dosage each day. However, if you want to make sure you’re getting the best treatment for your needs, it could be worth discussing with your doctor which option they recommend for you based on your medical history and lifestyle. 


What is the difference between Saxenda and Wegovy? 

Saxenda and Wegovy both utilise active ingredients belonging to the same category of medications, referred to as GLP-1 receptor agonists. Saxenda is an injectable medication that has been approved by the FDA for treating obesity and helping to control weight. It works by increasing ghrelin production, the primary hormone that triggers appetite. Saxenda can be used along with diet and exercise to reduce calorie intake and help manage weight loss. The effects of Saxenda usually start within 1-2 weeks after initiating treatment, although it can take 3-4 weeks or longer for the full effect to be seen.

In comparison, Wegovy is a brand-name prescription medication with semaglutide as its active ingredient. It acts differently from Saxenda in that it decreases hunger signals when taken before meals and helps control cravings throughout the day. Additionally, Wegovy helps aid in glucose regulation, making it beneficial for those with type 2 diabetes and pre-diabetes who are trying to manage their blood sugar levels. The effects of Wegovy typically set in later than with Saxenda – having taken 6-12 weeks for one’s appetite and metabolism to adjust – but in exchange provide long-lasting control over hunger hormones and glucose regulation. They both have a similar treatment plan that requires the weight loss treatment to be paired with regular exercise and a healthy diet. 


Wegovy and Saxenda differ significantly in their dosing regimens. Wegovy injections are self-administered once-weekly injections, whereas Saxenda requires daily injections. Wegovy maintains its effectiveness in the body for a full seven days, while Saxenda’s impact lasts only 24 hours. Given the less frequent need for injections, many individuals may find Wegovy a more convenient option for weight loss.

Both weight loss medications are available in pen form for injections. Wegovy pens offer the lowest dose of 0.25 mg, 0.5 mg, 1.0 mg, 1.7 mg, and 2.4 mg, whereas Saxenda pens are prescribed in strengths of 0.6 mg, 1.2 mg, 1.8 mg, 2.4 mg, and 3 mg.
