The new Mounjaro saving card can save you $575 a month until the end of 2023 if you are eligible and your insurance does not cover Tirezepatide. If you do have health insurance that will cover a portion of the costs, the new Mounjaro coupon may save you $975 a month (estimate.) The coupon acts as a co-pay assistance program, allowing you to only have to pay $25 a month rather than a typical insurance co-pay.
