Authorized genericNot sold

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

Regular genericNot sold

Kanjinti 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.

Good to know

“Commercial insurance” means a plan from a job, from the marketplace, or one you buy yourself. A retiree plan that’s part of Medicare counts as Medicare. Co-pay cards can’t be used with Medicare (including Medicare Advantage), Medicaid, TRICARE or VA.
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 the clinic’s billing office.
Don’t stop or change a medicine without talking to your pharmacist or prescriber.
