No authorized generic: There isn’t one.

No regular generic: Rebif Rebidose 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.

In the maker’s words

“You may pay as little as $0 co-pay or co-insurance for Rebif® (interferon beta-1a).”

From the maker’s offer on rebif.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.

Before you use a discount card

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, Rebif Rebidose’s own card may bring it to as little as $0 a prescription.

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.

What pharmacies pay

The average U.S. drugstores pay for each strength (source: Medicaid, September 23, 2026). What you pay depends on your plan or the pharmacy.

Good to know

There’s no authorized generic of Rebif Rebidose.
“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.
Don’t stop or change a medicine without talking to your pharmacist or prescriber.
