Brand nameNo maker’s card

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

Authorized genericNot sold

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

Regular genericNot sold

We didn’t find one. Generics usually come once the brand’s patents and exclusivity end. Until then, ask the pharmacy for Zanvastro’s cash price, or your plan what it charges.
