Authorized genericNot sold

There isn’t one. An authorized generic is HAEGARDA C1 Esterase Inhibitor Subcutaneous itself, from the same company, sold without the brand name, and usually for less. For now HAEGARDA C1 Esterase Inhibitor Subcutaneous is the only choice; its maker’s savings card can lower what you pay.

Regular genericNot sold

This medicine 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.

Most cards need a sign-up on the maker’s site, and many work only if your plan covers the drug. Then give the card’s details to your pharmacy.
