How much does Phenytoin (Dilantin) cost in Canada?
Canadian pharmacy listings in our data show Phenytoin priced from about $0.390 per tablet (converted to USD), before shipping. Pack size and pharmacy both affect the final total — see the Canada pricing table for specifics.
Why does Phenytoin (Dilantin) cost more in one country than the other?
Drug pricing is set separately in each country through different negotiation, regulatory, and distribution systems, so the same medication can legitimately carry different price tags on either side of the border. In this case, our data shows the US price is actually the lower of the two once a program like Cost Plus Drugs is factored in — the assumption that Canada is always cheaper doesn't hold for every drug.
How does insurance affect the price of Dilantin-125?
The cost of Dilantin-125 with insurance depends entirely on your specific plan's formulary and coverage details, including your copay or coinsurance. You should contact your insurance provider to confirm your coverage. If your insurance does not cover this medication, or if you have a high copay, you may explore other cost-saving options, such as pharmacy discount cards. These can be used regardless of insurance status, including for patients on Medicare or Medicaid, to compare and potentially lower your out-of-pocket expense at the pharmacy.
