Phenytoin: what pharmacies actually pay
Prices below are the National Average Drug Acquisition Cost (NADAC) — the federal government's weekly survey of what pharmacies actually pay their wholesalers, as of 07/22/2026. Your pharmacy's cash price includes their markup and dispensing cost, so it will be higher — but if it's many times this number, that's a signal to shop around.
| Form & strength | Pharmacy cost | Unit | Type |
|---|---|---|---|
| PHENYTOIN 125 MG/5 ML SUSP | $0.08 | per mL | Generic |
| PHENYTOIN 50 MG INFATAB CHEW | $0.19 | per tablet/unit | Generic |
| PHENYTOIN 50 MG TABLET CHEW | $0.19 | per tablet/unit | Generic |
| PHENYTOIN SOD EXT 100 MG CAP | $0.15 | per tablet/unit | Generic |
Rough math: a typical 30-day supply of one tablet/day equals 30× the per-unit cost.
