Brand nameNo maker’s card

We didn’t find a savings card or cash price from Nabi-HB’s maker. Ask the pharmacy for Nabi-HB’s cash price. With insurance, ask what your plan charges.

Authorized genericNot sold

There isn’t one. An authorized generic is Nabi-HB itself, from the same company, sold without the brand name, and usually for less. For now Nabi-HB is the only choice; ask the pharmacy for its cash price, or your plan what it charges.

Regular genericNot sold

Nabi-HB 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, ask the pharmacy for Nabi-HB’s cash price, or your plan what it charges.
