Semaglutide vs tirzepatide — which is right for me?
Tirzepatide produces greater weight loss and A1C reduction than semaglutide in head-to-head trials. Choice depends on goals, tolerability, prior response, and provider review.
Full answer
Semaglutide is a GLP-1 receptor agonist; tirzepatide adds GIP receptor agonism. In head-to-head SURPASS and SURMOUNT-style data, tirzepatide produced greater weight loss and greater A1C reduction at comparable dose tiers. Side-effect profiles overlap (gastrointestinal effects, slow titration). Candidacy decisions weigh goals, tolerability, prior medication response, cardiovascular history, and provider judgment. Within oMeds review, both are prescribed by licensed providers and paired with nutritional and behavioral support.
