In the maker’s words

“XERMELO patients may pay as little as $0 out-of-pocket for each prescription fill, dose, or cycle of XERMELO.”

From the maker’s offer on copay.xermelo.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 Xermelo itself, from the same company, sold without the brand name, and usually for less. For now Xermelo 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.

Good to know

“Commercial insurance” means a plan from a job, from the marketplace, or one you buy yourself. A retiree plan that’s part of Medicare counts as Medicare. Co-pay cards can’t be used with Medicare (including Medicare Advantage), Medicaid, TRICARE or VA.
Most cards need a sign-up on the maker’s site, and many work only if your plan covers the drug. Then give the card’s details to your pharmacy.
Don’t stop or change a medicine without talking to your pharmacist or prescriber.
