Maker’s card or discount card?
A discount card like GoodRx lowers the pharmacy’s cash price, but for a brand-name drug that price often stays high. Compare it with the maker’s price above. You can usually use one or the other on a fill, not both.

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