Is tirzepatide better than semaglutide for weight loss?

Clinical trial data suggests tirzepatide produces greater average weight loss (20-22% vs 15-17%). However, individual responses vary. Some patients respond better to one over the other. Your healthcare provider can help determine which is right for you.

How quickly does tirzepatide work?

Most people notice reduced appetite within 1-2 weeks. Significant weight loss typically begins by week 4-8. Maximum weight loss is achieved over 72+ weeks of consistent use at the maintenance dose.

Can I switch from semaglutide to tirzepatide?

Yes, switching is possible and sometimes recommended for patients who have plateaued on semaglutide. Start at the lowest tirzepatide dose (2.5mg) regardless of your previous semaglutide dose. Consult your healthcare provider for guidance.

What blood tests should I monitor on tirzepatide?

Similar to semaglutide: HbA1c, fasting glucose, lipid panel, kidney function, and liver enzymes. Some providers also monitor thyroid function. Our GLP-1 blood testing guide provides complete panel recommendations.
