Ask for the cash price
Genglycos
Genglycos 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.
- Ask your pharmacy for Genglycos’s cash price, and one or two other pharmacies too.

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