Frequently Asked Questions
Which is more effective, semaglutide or tirzepatide?
Clinical trials show tirzepatide produces greater average weight loss (approximately 21 percent) compared to semaglutide (approximately 15 percent), due to its dual receptor mechanism.
Is tirzepatide the same as semaglutide?
No, they are different medications. Semaglutide activates only the GLP-1 receptor, while tirzepatide activates both GLP-1 and GIP receptors, which is why it tends to produce greater weight loss.
Which has fewer side effects, semaglutide or tirzepatide?
Both medications have similar side effect profiles, primarily nausea, constipation, and fatigue during dose escalation. Individual tolerance varies, and your provider can help determine which is better suited to you.
