In the maker’s words

“Eligible patients with commercial or private insurance may pay as little as $0 out of pocket per fill for CTEXLI.”

From the maker’s offer on mirumaccessplus.com, checked November 2, 2026. Co-pay cards can’t be used with Medicare (including Medicare Advantage), Medicaid, TRICARE or VA.

Maker’s card or discount card?

A discount card like GoodRx lowers the pharmacy’s cash price, but for a brand-name drug that price often stays high. Compare it with the maker’s card above. You can usually use one or the other on a fill, not both.

Authorized genericNot sold

There isn’t one. An authorized generic is Ctexli itself, from the same company, sold without the brand name, and usually for less. For now Ctexli is the only choice; its maker’s savings card can lower what you pay.

Regular genericNot sold

We didn’t find one. Generics usually come once the brand’s patents and exclusivity end. Until then, the maker’s savings card is the way to pay less.
