≈ $0.23 per tabletPhenytoin cost without insurance
The figures here are what US retail pharmacies pay for generic phenytoin: about $0.23 per tablet (50 mg tablet), so $6.95 for a 30-day supply at one a day. If you pay cash, the pharmacy adds a dispensing fee and its margin, so expect to pay more than this, and prices differ between pharmacies for the same prescription.
With insurance or Medicare Part D you usually pay a fixed co-pay or co-insurance instead. Ask for the generic rather than the brand, compare a few pharmacies, and check discount programs: for cheap generics a cash price can be lower than your co-pay.

How NADAC prices work in the United States
Prices on this page are the National Average Drug Acquisition Cost (NADAC): the average price US retail pharmacies pay wholesalers for the drug, per tablet, capsule, mL or gram, from a monthly survey run for the Centers for Medicare & Medicaid Services (CMS). It is not the price on your receipt. Pharmacies add a dispensing fee and a margin, so the cash price without insurance is higher, often much higher, while your co-pay with insurance depends on your plan. Discount programs and low-cost pharmacies often sell common generics close to this cost plus a fee.
