Frequently Asked Questions

Should I switch from Saxenda to Wegovy?

If you want greater weight loss with less frequent injections, Wegovy is the upgrade. Discuss with your doctor — they'll typically start you at the lowest Wegovy dose and titrate up.

Are Wegovy and Saxenda the same thing?

No. Wegovy contains semaglutide (newer, more potent) while Saxenda contains liraglutide (older, first-generation). Both are GLP-1 receptor agonists but different molecules.

Which has better insurance coverage?

Coverage varies by plan. Both are approved for weight management, but Saxenda has been available longer and may be on more formularies. Always check your specific plan.
