How do semaglutide and tirzepatide differ?
Semaglutide acts as a GLP-1 receptor agonist. Tirzepatide is a GIP receptor and GLP-1 receptor agonist. This difference in receptor targets is useful for understanding their descriptions, but counting receptors does not establish a comparative clinical outcome.

Both labels contraindicate the named medicine with a personal or family history of medullary thyroid carcinoma, or Multiple Endocrine Neoplasia syndrome type 2. The WEGOVY prescribing information also discusses acute pancreatitis among serious adverse reactions. These selected points do not replace the full prescribing information.
