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 price 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 Gonal-f RFF Redi-ject itself, from the same company, sold without the brand name, and usually for less. For now Gonal-f RFF Redi-ject is the only choice; its maker’s savings card can lower what you pay.

Regular genericNot sold

This medicine is a biologic. Biologics don’t have generics, but some have biosimilars or an unbranded version from the same maker. Ask your pharmacist or prescriber whether one is sold. Generics usually come once the brand’s patents and exclusivity end. Until then, the maker’s savings card is the way to pay less.
