Key Takeaways
- Ozempic (semaglutide) produces ~15% weight loss vs ~8% for Saxenda (liraglutide)
- Ozempic is a weekly injection; Saxenda requires a daily injection
- Both are FDA-approved GLP-1 medications — Saxenda for weight loss, Ozempic for diabetes (Wegovy = semaglutide for weight loss)
- Side effects are similar but Saxenda's daily dosing may cause more consistent nausea
- Both cost ~$1,000-$1,300/month; compounded semaglutide from $147/month is far cheaper
Quick answer: Saxenda vs Ozempic
Saxenda (liraglutide) and Ozempic (semaglutide) are both injectable GLP-1 receptor agonists, but semaglutide is the newer, more effective generation. Ozempic produces roughly double the weight loss of Saxenda in clinical trials, with the added convenience of once-weekly dosing instead of daily injections. For most patients seeking weight loss in 2026, semaglutide (Ozempic/Wegovy) or compounded semaglutide is the better choice.

Weight loss results: Saxenda vs Ozempic
Saxenda (SCALE trials)
The SCALE clinical trial program evaluated liraglutide 3.0mg/day for weight management:
- SCALE 1: 8.0% mean weight loss at 56 weeks (vs 2.6% for placebo)
- SCALE 2: 6.0% weight loss in patients with prediabetes
- 33% of patients achieved ≥10% weight loss
- Results plateau after 6 months on maintenance dose
Ozempic/Wegovy (STEP and SUSTAIN trials)
Semaglutide at weight loss doses dramatically outperformed liraglutide:
- STEP 1: 14.9% mean weight loss at 68 weeks (2.4mg/week)
- STEP 4: 17.4% sustained weight loss with continued treatment
- 32% of patients achieved ≥20% weight loss
- Results continue improving up to week 68 and beyond
Dosing comparison
Saxenda dosing schedule (daily)
- Week 1: 0.6mg/day
- Week 2: 1.2mg/day
- Week 3: 1.8mg/day
- Week 4: 2.4mg/day
- Week 5+: 3.0mg/day (maintenance)
Ozempic dosing schedule (weekly)
- Week 1-4: 0.25mg/week
- Week 5-8: 0.5mg/week
- Week 9+: 1.0mg/week (max for diabetes)
- For weight loss (Wegovy): Up to 2.4mg/week over 16 weeks
The weekly dosing of Ozempic is a major quality-of-life advantage. Many patients find daily injections burdensome and adherence drops over time. With Ozempic, you inject once and forget about it for a week.
Side effects comparison
| Side effect | Saxenda (%) | Ozempic (%) |
|---|---|---|
| Nausea | 40-55% | 20-40% |
| Diarrhea | 20-30% | 10-20% |
| Vomiting | 12-20% | 5-15% |
| Constipation | 15-20% | 5-10% |
| Injection site reactions | 5-10% | 3-5% |
Saxenda tends to cause more nausea because daily dosing maintains consistently high drug levels. Ozempic's weekly dosing creates a smoother pharmacokinetic profile that many patients tolerate better.
Cost comparison
- Saxenda: ~$1,300/month without insurance
- Ozempic: ~$900-$1,000/month without insurance
- Compounded semaglutide: From $147/month (same as Ozempic active ingredient)
Both brand-name options are expensive. Compounded semaglutide offers the same active ingredient as Ozempic at 85% less cost. Check your eligibility for compounded semaglutide online.
Which should you choose?
Choose Ozempic (or compounded semaglutide) if:
- You want maximum weight loss (~15%)
- You prefer weekly injections over daily
- You want the most cost-effective option (compounded: $147/month)
- You want the GLP-1 with the strongest clinical evidence
Choose Saxenda if:
- You tried semaglutide and had intolerable side effects
- Your insurance covers Saxenda but not Ozempic/Wegovy
- Your provider specifically recommends liraglutide for your case
Frequently asked questions
Is Saxenda still prescribed in 2026?
Yes, but less frequently. Most providers now prefer semaglutide (Ozempic/Wegovy) or tirzepatide (Zepbound/Mounjaro) because they produce more weight loss with less frequent dosing. Saxenda remains an option for patients who do not respond to or tolerate newer GLP-1s.
Can I switch from Saxenda to Ozempic?
Yes. Your provider will typically stop Saxenda and start Ozempic at the beginning dose (0.25mg/week), then titrate up. Since they are different molecules, there is no direct dose conversion. For more on switching, read our GLP-1 switching guide.
Conclusion
Ozempic (semaglutide) is clearly superior to Saxenda (liraglutide) for weight loss — producing nearly double the weight loss with weekly instead of daily dosing. For the best value, compounded semaglutide from $147/month delivers the same active ingredient as Ozempic at a fraction of the cost.
