Carac vs. its authorized generic and generics

How to pay the least

Ask for the cash price

Authorized generic

Carac itself, without the brand name. It usually costs less than Carac.

Ask your pharmacy for the cash price of Carac’s authorized generic. Its NDC is on this page; the pharmacy may need to order it.See its NDC
Ask for Carac’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.

What to say at the pharmacy

“Before you fill my Carac, can you tell me what I’d pay for the brand, for the authorized generic from Dr. Reddy's Laboratories (NDC 75907-169-11)?”

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

Good to know

It may look different from Carac (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/carac/
