If you’re considering a prescription medication to support your weight loss, two names come up again and again: Wegovy and Saxenda.

Both are GLP-1-based treatments that help regulate appetite and support long-term weight loss. Both are available in New Zealand. But they aren’t the same. Choosing the right one depends on your goals, preferences, and clinical profile.

Let’s compare them side by side.

Wegovy: Best for Significant, Sustained Weight Loss

Best for:

  • People who prefer weekly dosing
  • Those who meet strict eligibility criteria
  • Patients seeking maximum weight loss support

Saxenda: Best for Gradual Weight Loss and Daily Routine

Saxenda may be a better fit for people who prefer daily injections and want a slightly more gradual approach to weight loss.

It has been available in New Zealand longer.

Best for:

  • Those who tolerate daily dosing
  • People who can’t access Wegovy
  • Patients preferring more gradual progress
