We didn’t find a savings card or cash price from Zyflo’s maker. Ask the pharmacy for Zyflo’s cash price. With insurance, ask what your plan charges.

Authorized genericNot sold

There isn’t one. An authorized generic is Zyflo itself, from the same company, sold without the brand name, and usually for less. For now Zyflo is the only choice; ask the pharmacy for its cash price, or your plan what it charges.

Regular genericNot sold

Sold only in a different form, strength or formula. Switching to one would need a new prescription, so ask your prescriber whether it could work for you. Generics usually come once the brand’s patents and exclusivity end. Until then, ask the pharmacy for Zyflo’s cash price, or your plan what it charges.
