It is also widely sought after for its powerful weight-loss effects. If you're searching for Costco Mounjaro pricing, availability, or savings programs, this guide breaks it all down.

What Is Mounjaro?

Mounjaro (tirzepatide) is a prescription injectable developed by Eli Lilly. Originally approved by the FDA to treat type 2 diabetes, it’s also being used off-label to support weight loss. Mounjaro works by mimicking hormones that regulate appetite, blood sugar, and digestion—helping patients feel fuller, eat less, and improve metabolic health.

The medication is part of the same class as Zepbound, but it’s typically prescribed under its original branding for diabetes management. Due to its effectiveness, interest in Costco Mounjaro continues to grow.

Can You Get Mounjaro Through Costco?

Yes. The Costco Pharmacy carries Mounjaro, and prescriptions can be filled at participating locations across the U.S. You don’t need a Costco membership to access the pharmacy in most states, though prices and availability may vary slightly for non-members.

Searching for Mounjaro at Costco has become increasingly common, especially among patients comparing options to reduce out-of-pocket costs.
