Key differences
- Different molecules. Wegovy is semaglutide (GLP-1 receptor agonist); Trulicity is dulaglutide (GLP-1 receptor agonist).
- Different approvals. Wegovy is approved for weight management; Trulicity is approved for type 2 diabetes. That shapes insurance coverage.

Which one fits you
That's a decision for you and your prescriber. The factors that usually decide it:
- Your diagnosis, which decides the approved option and often the coverage
- Whether your plan covers one and not the other
- A shot or a pill, weekly or daily
- How you tolerate side effects
- Cost if you pay yourself: see the cost index
