Wegovy and Victoza are both GLP-1 medications made by Novo Nordisk. But they're approved for different things and use different drugs.

Quick Comparison

Wegovy Victoza
Active drug Semaglutide Liraglutide
Drug class GLP-1 agonist GLP-1 agonist
FDA approval Weight management Type 2 diabetes
Injection frequency Once weekly Once daily
Dose range 0.25 mg – 2.4 mg (7.2 mg Wegovy HD for eligible patients) 0.6 mg – 1.8 mg
Maker Novo Nordisk Novo Nordisk

Different Purposes

Wegovy is approved for weight loss. It uses semaglutide at higher doses.

Victoza is approved for type 2 diabetes. It uses liraglutide at lower doses.

Wegovy vs Victoza for Weight Loss

Wegovy (semaglutide) is FDA-approved for chronic weight management, while Victoza (liraglutide) is approved for type 2 diabetes. Separate clinical trials reported about 15% average weight loss with Wegovy and roughly 5-7% with Victoza, but those results are not a head-to-head comparison and individual results vary.

Saxenda contains the same active drug as Victoza—liraglutide—but is separately labeled for chronic weight management and uses a different target dose. A prescriber determines which medication and dose are appropriate. See our Saxenda vs Wegovy comparison for that head-to-head.

Victoza vs Wegovy: Key Differences

  • Wegovy: About 15% average body weight loss in its clinical trials
  • Victoza: Roughly 5-7% body weight loss in separate studies

The separate trial results favor Wegovy for average weight loss, but they should not be treated as a direct comparison. Medication choice and dose changes belong with the prescriber. See our Wegovy HD guide for current labeling and trial context.

Side Effects

Both cause similar GLP-1 side effects:

  • Nausea (most common)
  • Diarrhea or constipation
  • Decreased appetite
  • Headache
  • Fatigue

Side effects are worst when you start and after dose increases. Most people adjust within a few weeks.

Convenience

  • Wegovy: One injection per week
  • Victoza: One injection per day

Weekly is more convenient for most people.

Cost

Wegovy: ~$1,350/month Victoza: ~$1,200-1,300/month

Both are often covered by insurance — Wegovy for weight loss, Victoza for diabetes. Check your formulary.

Who Should Choose Wegovy?

  • Your main goal is weight loss
  • You don't have diabetes
  • You want weekly injections
  • You want the strongest weight loss results among semaglutide options

Who Should Choose Victoza?

  • You have type 2 diabetes
  • Your insurance covers it and not Wegovy
  • You've used liraglutide before and it works
  • You prefer daily dosing

Bottom Line

Wegovy is built for weight loss and produces much more of it. Victoza is built for diabetes control and still helps with some weight loss.

The right choice depends on your health goals and insurance coverage.

Work with your healthcare provider to determine which medication is right for you. Individual results and experiences vary.
