Authorized genericNot sold

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

Regular genericNot sold

Bkemv 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.
