Is tirzepatide better than semaglutide for weight loss?
In the SURMOUNT-5 head-to-head trial, tirzepatide 15 mg achieved 20.2% weight loss compared to 13.7% with semaglutide 2.4 mg over 72 weeks. Tirzepatide produced statistically superior weight loss, though both medications showed significant results compared to placebo.
What is the maximum dose of tirzepatide?
The maximum FDA-approved dose of tirzepatide is 15 mg per week for weight management (Zepbound). Treatment starts at 2.5 mg weekly and increases by 2.5 mg every four weeks during titration. The dose escalation period takes approximately 20 weeks to reach the maximum dose.
