Saxenda vs Wegovy
Short answer: Saxenda (liraglutide) is injected daily, Wegovy (semaglutide) weekly. Both are GLP-1 medicines registered in the EU for weight management and available only on prescription through a doctor and pharmacy. The main practical difference lies in the injection frequency and the indicative effect. A doctor assesses which medicine is appropriate for you.
The key difference: daily vs weekly
Saxenda contains liraglutide and is injected once a day. Wegovy contains semaglutide and is injected once a week. For those who would rather inject as little as possible, the weekly frequency of Wegovy may be more convenient. Both are GLP-1 receptor agonists; read how that works at how GLP-1 works. How to inject safely is explained at injecting.

Action and ease of use
Both medicines slow gastric emptying and give a feeling of fullness, which reduces appetite. The difference in duration of action explains the frequency: liraglutide acts for a shorter time (daily), semaglutide for longer (weekly). With both, the dose is built up step by step to limit side effects; see dose titration. A doctor assesses the effect after a few weeks and discusses continuation. Not sure whether you are suitable?

Cost and reimbursement
Costs vary by medicine and pharmacy; a current overview is available at cost. Reimbursement depends on your indication and health insurance policy and is subject to strict conditions — read more about this at reimbursement. The daily Saxenda pen and the weekly Wegovy pen can work out differently in total monthly cost; discuss this with your doctor and pharmacy during the intake.
Which medicine when?
The choice depends on your situation, preferences and how your body responds. Those who are reluctant to inject daily may find the weekly Wegovy more convenient. On the other hand, daily dosing can offer advantages when adjusting the dose. This is a decision you make together with the doctor.
