Ask for the cash price

Authorized generic

Nitro-Dur itself, without the brand name. It usually costs less than Nitro-Dur.

Ask for Nitro-Dur’s cash price too, and pick the lower one.

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.

Good to know

It may look different from Nitro-Dur (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/nitro-dur/
