GAMMAGARD Liquid ERC savings card: up to $20,000 off a year with commercial insurance

How to pay the least

Ask for the cash price

GAMMAGARD Liquid ERC

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.

Ask your pharmacy for GAMMAGARD Liquid ERC’s cash price, and one or two other pharmacies too.
GAMMAGARD Liquid ERC’s savings card works only with insurance from a job or one you bought.

Insurance · up to $20,000 off a year

The card takes up to $20,000 a year off your co-pay.

In the maker’s words

“The maximum co-pay assistance available annually is $20,000…”

From the maker’s offer on takedapatientsupport.com, checked November 2, 2026. Co-pay cards can’t be used with Medicare (including Medicare Advantage), Medicaid, TRICARE or VA.

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 card 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 GAMMAGARD Liquid ERC itself, from the same company, sold without the brand name, and usually for less. For now GAMMAGARD Liquid ERC 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.

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.
Don’t stop or change a medicine without talking to your pharmacist or prescriber.
