Rethymic savings card from the maker

How to pay the least

Ask for the cash price

Rethymic

Rethymic 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 Rethymic’s cash price, and one or two other pharmacies too.

Authorized genericNot sold

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

Regular genericNot sold

Rethymic 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. Check the maker’s page for who can use it.
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.
