Wegovy and Saxenda are both injectable medications approved for weight loss. They're made by the same company (Novo Nordisk) but use different drugs. Wegovy uses semaglutide and is injected once a week. Saxenda uses liraglutide and is injected once a day.
Here's how they compare.
Quick Comparison
| Wegovy | Saxenda | |
|---|---|---|
| Active drug | Semaglutide | Liraglutide |
| Drug class | GLP-1 agonist | GLP-1 agonist |
| Injection frequency | Once weekly | Once daily |
| Dose range | 0.25 mg – 2.4 mg | 0.6 mg – 3 mg |
| Avg weight loss | ~15% | ~5-8% |
| FDA approval | Weight management (2021) | Weight management (2014) |
| Maker | Novo Nordisk | Novo Nordisk |

Weight Loss Results
Wegovy generally produces more weight loss. Semaglutide is a newer, more potent drug.
Wegovy (semaglutide 2.4 mg):
- Average: ~15% body weight loss over 68 weeks
- About 86% of participants lost at least 5% of body weight
- About one-third lost 20% or more
Saxenda (liraglutide 3 mg):
- Average: ~5-8% body weight loss over 56 weeks
- About 60% of participants lost at least 5% of body weight
Wegovy produces roughly 2-3 times more weight loss than Saxenda on average. This is a significant difference.
That said, individual results vary. Some people do better on Saxenda than the average. Some do worse on Wegovy. Your body's response matters more than trial averages.

Why Such a Difference?
Semaglutide (Wegovy) binds more strongly to GLP-1 receptors and stays in your body longer than liraglutide (Saxenda). This is why Wegovy can be injected weekly while Saxenda needs daily injections. The longer action and stronger receptor binding translate to more weight loss.
Dosing Schedules
Saxenda (daily)
- Week 1–4: 0.6 mg daily
- Week 5–8: 1.2 mg daily
- Week 9–12: 1.8 mg daily
- Week 13–16: 2.4 mg daily
- Week 17+: 3.0 mg daily (maintenance)
Wegovy (weekly)
- Month 1: 0.25 mg weekly
- Month 2: 0.5 mg weekly
- Month 3: 1.0 mg weekly
- Month 4: 1.7 mg weekly
- Month 5+: 2.4 mg weekly (maintenance)
Both use a slow ramp-up to help your body adjust and reduce side effects.
Daily vs Weekly: Which Is Better?
Weekly (Wegovy) advantages:
- One injection instead of seven
- Easier to remember
- Less "needle fatigue"
- More stable medication levels in your body
Daily (Saxenda) advantages:
- If you have a bad side effect day, it clears your system faster
- More flexibility to skip a dose if needed
- Some people prefer the daily routine
- Fewer injection site reactions per dose (smaller needle)
Most people prefer weekly. But daily isn't a dealbreaker.

Side Effects
Both medications cause similar side effects:
| Side Effect | Wegovy | Saxenda |
|---|---|---|
| Nausea | ~44% | ~40% |
| Diarrhea | ~30% | ~37% |
| Constipation | ~24% | ~19% |
| Vomiting | ~24% | ~20% |
The rates are similar. Wegovy has slightly higher rates of some side effects, likely because it's more potent. Saxenda causes more injection site reactions overall (more needles = more chances for irritation).
For most people, side effects are worst during the first few weeks and after dose increases. They improve over time.

Cost
| Wegovy | Saxenda | |
|---|---|---|
| List price/month | ~$1,349 | ~$1,442 |
| Savings card (with commercial insurance) | As low as $0–$25/month | As low as $25/month |
| Savings card (without insurance) | ~$650 for 2 fills, then full price | ~$199 first month, then full price |
Key point: Your actual cost depends entirely on your insurance. Some people pay $25/month for either medication. Others pay full price. Check with your plan.
Daily Saxenda may have higher hidden costs over time: more pens per month, more pharmacy visits, and potentially higher copays if you pay per prescription. Weekly Wegovy requires fewer pharmacy visits and less packaging.

Saxenda's Advantage: Track Record
Saxenda has been around longer (FDA approved 2014 vs 2021 for Wegovy). This means:
- More real-world data
- Better known long-term safety profile
- More doctors have experience with it
- Some insurance plans are more familiar with it
If you want a medication with a longer history, Saxenda has that.
Who Should Choose Wegovy?
- You want maximum weight loss
- You prefer weekly injections
- Your insurance covers it
- You want the additional heart health benefits shown in the SELECT trial
- You're starting fresh with GLP-1 treatment
Who Should Choose Saxenda?
- Your insurance covers Saxenda but not Wegovy
- You've used it before and it works
- You prefer daily dosing for more control
- You can't tolerate semaglutide
- You want a medication with a longer track record

Can You Switch?
Yes, many patients switch between GLP-1 medications.
Saxenda → Wegovy: Start at Wegovy's lowest dose (0.25 mg) and titrate up. Even if you were on Saxenda 3 mg. This is because the drugs are different and your body needs to adjust.
Wegovy → Saxenda: Start Saxenda at 0.6 mg and titrate up normally.
Don't switch on your own. Your doctor will guide the transition.
What About Rybelsus?
Rybelsus is oral semaglutide (a pill, not an injection). It's approved for diabetes but used off-label for weight loss.
Consider Rybelsus if:
- You hate needles
- Your insurance covers it
- You're okay with daily pills (must be taken on empty stomach)
Weight loss is typically less than Wegovy (lower dose availability).
Helpful Products for GLP-1 Treatment
- Sharps container — Required for safe needle disposal
- Ginger chews — Help manage nausea
- Large water bottle — Stay hydrated to reduce side effects
- Electrolyte packets — Prevent dehydration

Bottom Line
For most people, Wegovy is the better choice. It produces more weight loss with fewer injections.
Saxenda still has a role for people who want a daily routine, need a medication with a longer track record, or can't tolerate semaglutide.
The best GLP-1 is the one you can access, afford, and tolerate. Check which medication your insurance covers and at what cost, then talk to your doctor.
Work with your healthcare provider to determine which medication is right for you. Individual results vary.
