Your insurance company may cover your prescription for Mounjaro, but this will vary based on the insurance plan and drug benefits. The manufacturer of Mounjaro offers a savings card that can lower your cost to $25 for up to a 3-month supply, if you have commercial prescription insurance. You can download the coupon directly to your computer or phone and use it for 13 refills per calendar year. Your insurance may cover Mounjaro for type 2 diabetes but not for weight loss.
