Weight trajectories after last Tirzepatide or Semaglutide prescription across a federated health network

Abstract GLP-1 receptor agonist (GLP-1RA) discontinuation has been associated with weight regain. However, the real-world association between discontinuation of GLP-1RA prescriptions and weight change has not been explored. We assessed weight trajectories of 4,182 patients in the six months following their last GLP-1RA prescription. Approximately two-thirds of patients showed stable weight or continued weight loss during this period post the last known GLP-1RA prescription. In a representative subset of patients with clinician-documented discontinuation near the last prescription (N=300), a similar distribution of weight regain in a minority of patients was observed vs no regain in the majority of patients…
