We didn’t find a savings card or cash price from TNKase’s maker. Ask the pharmacy for TNKase’s cash price. With insurance, ask what your plan charges.
Authorized genericNot sold
There isn’t one. An authorized generic is TNKase itself, from the same company, sold without the brand name, and usually for less. For now TNKase is the only choice; ask the pharmacy for its cash price, or your plan what it charges.
Regular genericNot sold
TNKase 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 TNKase’s cash price, or your plan what it charges.
