What to say at the pharmacy

“Before you fill my Purixan, can you tell me what I’d pay for the brand, for the authorized generic from Nova Laboratories (NDC 62484-1020-4), and for a regular generic?”

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

Regular genericWho makes it

One company sells a generic of Purixan 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.

Good to know

It may look different from Purixan (color, shape, or markings). That’s normal for an authorized generic.
If your prescription says “dispense as written,” the pharmacy needs your prescriber’s OK to give you the authorized generic.
Cash prices can differ a lot from one pharmacy to the next, so it can pay to ask two. With insurance, what you pay depends on your plan.
If your pharmacy doesn’t stock it, they can often order it within a day or two.
Don’t stop or change a medicine without talking to your pharmacist or prescriber.

Prices change: confirm with the pharmacy before you fill. drugalt.com/drug/purixan/
