Authorized genericNot sold

There isn’t one. An authorized generic is Oxlumo itself, from the same company, sold without the brand name, and usually for less. For now Oxlumo 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.
