Transition timeline
Plan на 2-week prep + 12-week evaluation window. Most weight-loss outcomes can be re-assessed at the 12-week mark на the new medication.
Week −2: Decision + prescriber alignment
Confirm with your prescriber: dose-equivalent target, expected side-effect profile differences (tirzepatide → semaglutide), insurance implications.
Week −1: Last Compounded tirzepatide dose
Continue your current Compounded tirzepatide schedule. Compounded tirzepatide has a long half-life — semaglutide ~1 week, tirzepatide ~5 days — so effects persist для days after stopping.
Week 0: First Rybelsus dose
Restart titration from lowest Rybelsus dose. Overlap effect возможен в the first 7-10 days as Compounded tirzepatide 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 tirzepatide 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 tirzepatide, discuss reverting or trying a third option (often tirzepatide-based).
