In overweight or obese adults, tirzepatide produces significantly greater weight loss than semaglutide over a 6-month period, particularly in patients without diabetes.

If you are overweight or obese and considering medication, tirzepatide appears to offer greater weight loss benefits than semaglutide over a 6-month period, especially if you do not have diabetes. However, real-world effectiveness can vary based on adherence and cost, so discuss these factors with your provider.
