What pharmacies pay (NADAC)
The National Average Drug Acquisition Cost (NADAC) is the average price U.S. retail pharmacies paid to buy one unit of a medicine (one tablet, one mL or one gram), from a monthly survey of pharmacy invoices by the Centers for Medicare & Medicaid Services (CMS). State Medicaid programs use it to pay pharmacies.
This is not the price you pay. What you pay depends on your insurance (copay or coinsurance), your pharmacy and any discounts, and pharmacies also charge for filling a prescription. Ask your pharmacist or your health plan what your price will be.
| Strength and form | Generic or brand | Pharmacies pay |
|---|---|---|
| clonazepam 0.5 mg tablet | Brand: Klonopin | $2.68 per tablet Generic of the same strength and form: $0.0197 per tablet |
| clonazepam 1 mg tablet | Brand: Klonopin | $3.05 per tablet Generic of the same strength and form: $0.0245 per tablet |
| clonazepam 2 mg tablet | Brand: Klonopin | $4.25 per tablet Generic of the same strength and form: $0.0400 per tablet |

Which names get a brand page: a name the NDC Directory lists for a medicine, held by one company (the FDA application holder, or the company named on most of its products), that is not just a description, and that is not the only product of its medicine.
