Trulicity
Eli Lilly's weekly dulaglutide pen for type 2 diabetes, famous for ease of use rather than weight loss.
Trulicity made weekly GLP-1 therapy mainstream before semaglutide did, largely on the strength of its auto-injector — no visible needle, no dose dialing, one click. For type 2 diabetes it pairs solid glucose control with proven cardiovascular benefit.
Weight loss on Trulicity is real but small, typically 2–5 kg, and it holds no weight-management approval. In the weight-care landscape it functions as a comparison point and a starting place: many patients asking about Wegovy or Zepbound are currently on Trulicity for diabetes, and the switch conversation — indication, insurance, titration overlap — is one their prescriber navigates routinely.
