Medication switch
tirzepatide → semaglutide — re-titration required
Tirzepatide → semaglutide — typically insurance, side effects, or cost-driven.

Cross-ingredient switch — re-titration required
Zepbound uses tirzepatide; Wegovy uses semaglutide. 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.
Re-titrate from Wegovy 0.25 mg through the standard 16-week schedule to reach 2.4 mg. Each dose holds 4 weeks. Total transition typically 16 weeks.
GI symptoms commonly return during re-titration. Patients on Zepbound 15 mg reaching only Wegovy 2.4 mg may notice some weight regain — Wegovy max dose is below Zepbound max.
Our ranked telehealth providers handle switching prescriptions, prior authorizations, and pharmacy coordination — typically 1–3 business days end to end.

Most common reasons: insurance prefers Wegovy, you experienced severe GI side effects on tirzepatide (possibly related to the GIP component), or the Wegovy savings card is more accessible. Clinically, expect somewhat less weight loss at the lower max dose.
