Est. Cost
$299-$449/mo
Tirzepatide, marketed as Zepbound for weight management, is a first-in-class dual GIP/GLP-1 receptor agonist that has demonstrated what may be the most significant weight loss results of any approved medication to date. By activating two incretin hormone pathways instead of one, tirzepatide appears to offer enhanced appetite suppression and metabolic benefits compared to single-mechanism alternatives. While it carries a higher price tag than semaglutide, clinical data suggests it may deliver substantially greater weight reduction for many patients.

How Tirzepatide (Zepbound) Works
Tirzepatide is unique because it activates both GIP (glucose-dependent insulinotropic polypeptide) and GLP-1 receptors simultaneously. This dual mechanism may amplify the appetite-reducing and metabolic effects beyond what single-target GLP-1 medications can achieve alone. Like other GLP-1 drugs, it appears to slow gastric emptying and reduce hunger signals in the brain. The addition of GIP receptor activation is thought to further enhance fat metabolism and improve the body's insulin sensitivity, which may contribute to the greater weight loss observed in clinical studies.

Eligibility to Discuss With a Clinician
Tirzepatide is generally prescribed for adults with a BMI of 30 or greater, or a BMI of 27 or greater with at least one weight-related health condition. It may be particularly suitable for patients who have not achieved desired results with single-mechanism GLP-1 medications. As with other medications in this class, it is contraindicated in patients with a personal or family history of medullary thyroid carcinoma or MEN2.
