Medication switch
semaglutide → tirzepatide — re-titration required

Cross-ingredient switch — re-titration required
Ozempic uses semaglutide; Zepbound uses tirzepatide. You restart from the starter dose and re-titrate over 12–20 weeks to reduce GI side effects.
These medications use different active ingredients (semaglutide vs. tirzepatide). Re-titration from the starter dose is required to reduce GI side effects.
Stop Ozempic. Begin Zepbound 2.5 mg starter dose. Titrate 4 weeks at each step to 5 → 7.5 → 10 → 12.5 → 15 mg. Full titration is typically 16-20 weeks.
Expect GI symptoms during re-titration. Some patients describe tirzepatide as more potent appetite suppression than semaglutide at equivalent steps.
Zepbound on-label for weight management — easier PA than off-label Ozempic for weight loss. If you carry both Ozempic and Wegovy savings cards, the Zepbound card needs separate signup.

Yes, with prescriber approval. Zepbound is FDA-approved for weight management (BMI ≥30 or ≥27 with comorbidity). The transition requires re-titrating from the starter dose because the active ingredient changes from semaglutide to tirzepatide.
