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