Tirzepatide vs semaglutide and liraglutide for weight loss in patients with overweight or obesity without diabetes: A short-term cost-effectiveness analysis in the United States

Subcutaneous tirzepatide and oral semaglutide were cost-effective therapies compared with subcutaneous liraglutide and subcutaneous semaglutide for the short-term management of obesity in adults without diabetes. At or under a willingness-to-pay threshold of $150,000 per QALY, subcutaneous tirzepatide was most cost-effective, surpassing oral semaglutide. These findings provide valuable insights for health care decision-makers in selecting antiobesity medications.
