Zepbound
FDA ApprovedChronic weight management
How Zepbound Works
Zepbound (tirzepatide 15mg) is the FDA-approved weight management version of tirzepatide. As a dual GIP/GLP-1 receptor agonist, it targets two incretin pathways simultaneously, producing some of the most significant weight loss results seen in any medication to date. It works by reducing appetite, slowing gastric emptying, and improving how your body processes food and regulates blood sugar.
In the SURMOUNT-1 trial, Zepbound at the 15mg dose helped patients lose an average of 22.5% of body weight (about 52 lbs for a 230 lb person) over 72 weeks. Over half of participants on the highest dose lost at least 20% of their body weight, and about a third lost 25% or more.

Frequently Asked Questions
How much does Zepbound cost per month?
Zepbound costs approximately $1,000-$1,200/month without insurance. With insurance, copays vary widely. Eli Lilly offers savings programs for eligible patients. Compounded tirzepatide may be available for $200-$500/month through some telehealth providers.
Is Zepbound more effective than Wegovy?
Clinical data suggests Zepbound (tirzepatide) produces greater average weight loss than Wegovy (semaglutide) - 22.5% vs 14.9% of body weight in their respective trials. However, direct comparison is difficult since the trials had different populations. Both are effective options.
Who qualifies for Zepbound?
Zepbound is FDA-approved for adults with BMI 30+ (obesity) or BMI 27+ (overweight) with at least one weight-related condition such as high blood pressure, type 2 diabetes, or high cholesterol. A healthcare provider must determine if it is appropriate for you.
How long does it take Zepbound to work?
Most patients notice appetite reduction within 1-2 weeks. Measurable weight loss typically begins within the first month, with the most dramatic results occurring between months 3-9 as the dose is gradually increased to the maintenance level.
