Ozempic and Victoza are both GLP-1 medications used to treat type 2 diabetes. They come from the same company but use different drugs.
Quick Comparison
| Ozempic | Victoza | |
|---|---|---|
| Active drug | Semaglutide | Liraglutide |
| Drug class | GLP-1 agonist | GLP-1 agonist |
| FDA approval | Type 2 diabetes | Type 2 diabetes |
| Injection frequency | Once weekly | Once daily |
| Dose range | 0.25 mg – 2 mg | 0.6 mg – 1.8 mg |
| Maker | Novo Nordisk | Novo Nordisk |
How They Work
Both mimic the GLP-1 hormone to help your body:
- Produce more insulin when blood sugar is high
- Make less glucagon (a hormone that raises blood sugar)
- Slow down digestion
Ozempic uses semaglutide, a newer drug that lasts longer in your body.
Victoza uses liraglutide, an older drug that's been used since 2010.
A1C Reduction
- Ozempic: Lowers A1C by about 1.3-1.8% on average
- Victoza: Lowers A1C by about 1.0-1.5% on average
Ozempic tends to produce slightly better blood sugar control at max doses.
Weight Loss
Both lead to weight loss as a bonus:
- Ozempic: ~10-15% body weight loss in studies
- Victoza: ~5-7% body weight loss in studies
Ozempic generally produces more weight loss.
Side Effects
Both cause similar GLP-1 side effects:
- Nausea (most common)
- Diarrhea or constipation
- Decreased appetite
- Headache
- Vomiting (less common)
Side effects are worst when you start and after dose increases. Most people adjust within a few weeks.
Convenience
- Ozempic: One injection per week
- Victoza: One injection per day
Weekly is more convenient. But daily dosing gives you more control.
Cost
Ozempic: ~$900-1,000/month Victoza: ~$1,200-1,300/month
Both are often covered by insurance for diabetes. Ozempic is slightly cheaper at list price.
Who Should Choose Ozempic?
- You want weekly injections
- You want stronger A1C reduction
- You want more weight loss as a bonus
- You're starting GLP-1 treatment fresh
Who Should Choose Victoza?
- You've used it before and it works
- Your insurance covers it and not Ozempic
- You prefer daily dosing
- You can't tolerate semaglutide
Bottom Line
Ozempic is newer, weekly, and generally more effective for both blood sugar and weight loss. Victoza is older, daily, and still works well for many people.
