Subcutaneous tirzepatide is the most cost-effective anti-obesity medication for adults without diabetes over a 68-week period, demonstrating superior incremental cost-effectiveness compared to oral semaglutide, subcutaneous semaglutide, and subcutaneous liraglutide.

For adults without diabetes seeking weight loss, subcutaneous tirzepatide offers the best value for money among current GLP-1 based therapies over a 68-week period. It is more cost-effective than oral semaglutide, subcutaneous semaglutide, and subcutaneous liraglutide. While oral semaglutide is a good alternative for those who dislike injections, tirzepatide provides superior cost-effectiveness. Patients should discuss these options with their healthcare provider, considering factors like injection preference, insurance coverage, and potential side effects.

GoodSupportsHIGH confidence
In the base-case analysis, subcutaneous tirzepatide and oral semaglutide emerged as cost-effective vs subcutaneous liraglutide and subcutaneous semaglutide. Compared with oral semaglutide, subcutaneous tirzepatide is cost-effective, with an ICER of $34,212 per QALY gained at 68 weeks. Based on a WTP threshold of $150,000 per QALY, subcutaneous tirzepatide was most cost-effective among the 4 medications.
