Possible Reduction of Early Weight Loss with Tirzepatide in a Patient Also Taking Levosulpiride: A Case Report and Explanation

Updated

Abstract

An overall weight loss of 11 kg was observed following the adjustment of tirzepatide dosage in a patient with obesity and type 2 diabetes.

  • Tirzepatide therapy was initiated at a dose of 5 mg weekly alongside levosulpiride.
  • Only modest weight loss occurred during the initial phase of treatment, followed by a weight plateau.
  • After discontinuing levosulpiride and increasing tirzepatide to 7.5 and 10 mg weekly, significant weight reduction was noted.
  • Glycemic control improved substantially, with glycated hemoglobin (HbA1c) levels reaching 5.0%.
  • No episodes of pancreatitis were reported, despite an asymptomatic increase in lipase levels.
  • The case suggests a possible interaction between dopaminergic antagonism and incretin receptor agonism that may affect weight response.
