Saxenda vs Wegovy: what is the difference?
Saxenda is the brand name for liraglutide 3 mg, a GLP-1 receptor agonist taken once daily. Wegovy is the brand name for semaglutide 2.4 mg, taken once weekly. Both are FDA-approved for chronic weight management, but they differ in effectiveness, dosing, and convenience.
Wegovy has largely replaced Saxenda as the preferred injectable weight-loss medication because it produces more weight loss with weekly dosing. However, Saxenda still has a role for some patients.
How do Saxenda and Wegovy work?
Both medications are GLP-1 receptor agonists. They reduce appetite, slow stomach emptying, and improve blood sugar control. The key difference is the molecule:
- Liraglutide (Saxenda): Shorter-acting, requires a daily injection.
- Semaglutide (Wegovy): Longer-acting, requires a weekly injection, and produces stronger average weight loss.
Clinical results: Saxenda vs Wegovy weight loss
Clinical trials show a clear difference between the two medications:
| Metric | Saxenda (SCALE trial) | Wegovy (STEP trials) |
|---|---|---|
| Average weight loss | ~8% at 56 weeks | ~14.9% at 68 weeks |
| Patients losing ≥5% | ~63% | ~83% |
| Patients losing ≥10% | ~33% | ~56% |
| Patients losing ≥15% | ~14% | ~29% |
| Patients losing ≥20% | ~5% | ~10% |
| For a 200 lb person | ~16 lbs lost | ~30 lbs lost |
| For a 250 lb person | ~20 lbs lost | ~37 lbs lost |
In other words, Wegovy produces nearly twice as much average weight loss as Saxenda. This is why most providers and patients prefer semaglutide when available.
Dosing schedules compared
Saxenda (liraglutide) dosing chart
Saxenda is injected once daily, usually in the abdomen, thigh, or upper arm. The dose gradually increases over 5 weeks to minimize GI side effects:
| Week | Daily dose | Notes |
|---|---|---|
| Week 1 | 0.6 mg | Starting dose — titration begins |
| Week 2 | 1.2 mg | Increase if tolerated |
| Week 3 | 1.8 mg | Continue titration |
| Week 4 | 2.4 mg | Continue titration |
| Week 5+ | 3.0 mg | Maintenance dose |
Wegovy (semaglutide) dosing chart
Wegovy is injected once weekly. The dose increases every 4 weeks:
| Week | Weekly dose | Notes |
|---|---|---|
| Weeks 1-4 | 0.25 mg | Starting dose — titration begins |
| Weeks 5-8 | 0.5 mg | Increase if tolerated |
| Weeks 9-12 | 1.0 mg | Continue titration |
| Weeks 13-16 | 1.7 mg | Continue titration |
| Week 17+ | 2.4 mg | Maintenance dose |
Many patients strongly prefer weekly injections because they are easier to remember and less disruptive to daily life. See our GLP-1 Dose Calculator for personalized guidance.

Side effects: Saxenda vs Wegovy
Both Saxenda and Wegovy cause similar gastrointestinal side effects. Here's a detailed comparison:
| Side effect | Saxenda | Wegovy |
|---|---|---|
| Nausea | ~40% (most common) | ~44% (most common) |
| Diarrhea | ~20% | ~23% |
| Vomiting | ~12% | ~19% |
| Constipation | ~11% | ~11% |
| Decreased appetite | ~17% | ~17% |
| Injection site reactions | More common (daily) | Less common (weekly) |
| Discontinuation rate | ~10-15% | ~10-15% |
Daily injections with Saxenda may cause more injection site reactions due to the frequency. Wegovy's longer half-life means side effects may persist longer after each dose but are often less intense day-to-day. See our GLP-1 Nausea Relief Guide for tips.

Without insurance
| Option | Monthly cost | Notes |

Switching from Saxenda to Wegovy: complete guide
Yes, many patients switch from Saxenda to Wegovy under medical supervision. Common reasons include better weight loss on semaglutide, fewer injections, or side effect concerns. Here's what to expect:
The switching process
- Consult your provider: Discuss the switch with your prescribing doctor or telehealth provider
- Stop Saxenda: Take your last Saxenda dose as directed, then stop
- Wait 2-3 days: Allow liraglutide to clear your system (half-life ~13 hours)
- Start Wegovy at 0.25mg: Begin at the lowest Wegovy dose, even if you were on the max Saxenda dose
- Titrate up: Follow the standard Wegovy titration schedule (0.25 → 0.5 → 1.0 → 1.7 → 2.4mg)
- Monitor side effects: Some patients experience a brief return of side effects during the transition
Most patients complete the transition within 16-20 weeks (following Wegovy's standard titration schedule). The key is not to skip the titration — even if you were on Saxenda 3mg, you should start Wegovy at 0.25mg to minimize side effects.
Can you switch from Wegovy to Saxenda?
Less common, but possible. Some patients switch from Wegovy to Saxenda if they experience intolerable side effects from semaglutide or if their insurance covers Saxenda but not Wegovy. The process is similar: stop Wegovy, wait 1 week (half-life ~7 days), then start Saxenda at 0.6mg.
What patients say: Saxenda vs Wegovy (Reddit & forums)
Based on patient reports from Reddit (r/SaxendaGLP1, r/wegovy, r/loseit) and online forums:
| Topic | Saxenda experiences | Wegovy experiences |
|---|---|---|
| Weight loss satisfaction | Mixed — some see results, many plateau | Generally positive — more consistent loss |
| Daily injection burden | Common complaint — bruising, fatigue from daily shots | N/A — weekly is preferred |
| Nausea severity | Moderate, often improves after titration | Moderate to severe during titration, improves at maintenance |
| Cost complaints | Very common — $1,300+/month is prohibitive | Same — but compounded options are cheaper |
| Switching experiences | Many report switching TO Wegovy for better results | Few switch away from Wegovy |
These are anecdotal reports and do not constitute medical advice. Individual experiences vary widely.

Conclusion
Both Saxenda and Wegovy are FDA-approved for weight loss, but Wegovy is more effective and more convenient. For most US adults seeking maximum weight loss, semaglutide is the better choice. If you cannot access or tolerate semaglutide, Saxenda remains a valid option.
