Use this table as a starting reference only. Final dose depends on your tolerance, weight-loss trajectory, and prescriber guidance. Never self-titrate based on a chart.

Transition timeline
Plan on 2-week prep + 12-week evaluation window. Most weight-loss outcomes can be re-assessed at the 12-week mark on the new medication.
Week −2: Decision + prescriber alignment
Confirm with your prescriber: dose-equivalent target, expected side-effect profile differences (dulaglutide → semaglutide), insurance implications.
Week −1: Last Trulicity dose
Continue your current Trulicity schedule. Trulicity has a long half-life — semaglutide ~1 week, tirzepatide ~5 days — so effects persist for days after stopping.
Week 0: First Wegovy dose
Restart titration from lowest Wegovy dose. Overlap effect possible in the first 7-10 days as Trulicity clears.
Weeks 1-4: Stabilization
Side-effect profile shifts. Adjust to new effect onset timing. Track weight + appetite.
Weeks 4-12: Re-evaluation
Compare outcomes to your Trulicity baseline. If weight-loss trajectory hasn't improved by week 12, discuss whether the switch was right.
Beyond 12 weeks
If outcomes good, continue. If switch underperformed Trulicity, discuss reverting or trying a third option (often tirzepatide-based).
FAQ — Trulicity → Wegovy
Can I take Trulicity and Wegovy together?
No. Combining GLP-1 medications isn't done outside clinical trials. Stop Trulicity before starting Wegovy; the long half-lives mean overlap occurs naturally.
Will I lose ground when switching from Trulicity to Wegovy?
Possibly temporarily. Most patients maintain weight during a clean switch when restart dose is appropriate. The bigger risk is regression if the switch fails to match Trulicity efficacy. Plan and 12-week evaluation window.
Does insurance cover Wegovy if it covered Trulicity?
Different molecule means different formulary placement. Run a fresh prior authorization for Wegovy — coverage of Trulicity doesn't transfer automatically.
How long does Trulicity stay in my system after the last dose?
Liraglutide has a 13-hour half-life — effects clear in 2-3 days. Daily dosing means transitions are quicker.
