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 (semaglutide → semaglutide), insurance implications.
Week −1: Last Compounded semaglutide dose
Continue your current Compounded semaglutide schedule. Compounded semaglutide has a long half-life — semaglutide ~1 week, tirzepatide ~5 days — so effects persist for days after stopping.
Week 0: First Ozempic dose
Start Ozempic at your equivalent dose (see table below). Combined effect may be elevated in the first week as Compounded semaglutide 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 Compounded semaglutide 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 Compounded semaglutide, discuss reverting or trying a third option (often tirzepatide-based).

Ozempic is FDA-approved — insurance coverage is more typical. Verify formulary status and whether prior authorization is required for Ozempic specifically.
How long does Compounded semaglutide stay in my system after the last dose?
