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 |
|---|---|---|
| sodium phosphate, dibasic, heptahydrate 3.5 g/66 mL · sodium phosphate, monobasic 9.5 g/66 mL enema | Brand: Pedia-Lax | $0.0204 per mL |
| sodium phosphate, dibasic, heptahydrate 7 g/118 mL · sodium phosphate, monobasic 19 g/118 mL enema | Brand: Fleet | $0.0084–$0.0095 per mL 2 packages, lowest to highest |

Shown only where a package’s NDC code matches the NADAC list exactly, and only for that exact strength and form: nothing is averaged across strengths.
