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

Authorized genericNot sold

There isn’t one. An authorized generic is Cortrosyn itself, from the same company, sold without the brand name, and usually for less. A regular generic is sold, with the same active ingredient: ask the pharmacy for its price.

Regular genericWho makes it

One company sells a generic of Cortrosyn that the FDA rates a substitute. A pharmacy fills whichever one it stocks. To get a certain maker, ask for it by name; most pharmacies can order it in a day or two.

It’s mostly filled by specialty pharmacies. Your prescriber’s office or insurer can tell you which one to use.

Paying cash? Ask for each one’s cash price. With insurance, ask what your plan charges for each.
