No authorized generic: There isn’t one.
No regular generic: Betaseron 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.

BETAPLUS $0 Copay Program (Bayer Savings Card)
With commercial insurance
$0 a fill
No insurance
This card needs commercial insurance. The maker doesn’t list a cash price on this page.
“$0 copay, up to maximum program benefit or patient total program benefit.”
From the maker’s offer on betaseron.com, checked September 25, 2026. What you pay depends on your plan. Co-pay cards can’t be used with Medicare (including Medicare Advantage), Medicaid, TRICARE or VA.
Discount cards like GoodRx take money off the pharmacy’s cash price. For a brand-name drug, that price is often still high. With commercial insurance, Betaseron’s own card may bring it to $0 a fill.
Look up the discount-card price, then compare it with this estimate. You can use a maker’s card or a discount card, but usually not both on the same fill.
