Switching from Semaglutide to Tirzepatide: What You Need to Know
Quick Answer: Can you switch from semaglutide to tirzepatide?
Yes — switching from semaglutide to tirzepatide is common and safe when supervised by a licensed provider, typically considered when weight loss plateaus or side effects persist. Your provider selects an appropriate tirzepatide starting dose based on your current semaglutide dose; you should never overlap the two medications or switch on your own.
