Each row is one product from one pharmacy, shown in the pack size with the lowest price per unit; its other pack sizes are listed under “other pack sizes”. Price per unit = the pack price divided by the units in the pack, before shipping; we sort by it and don't assume how long a pack lasts. Total with shipping = the pack price plus the pharmacy's shipping fee for one order. Prices checked Nov 11, 2026 on each pharmacy's website, in U.S. dollars (converted when a pharmacy prices in Canadian dollars). The lowest price at the top of this page uses only packs whose maker the pharmacy names, or whose product country and ships-from country it states. Prices change often; confirm at checkout. U.S. rows: the cash price a U.S. pharmacy published on its own website on the date shown, plus its standard shipping; no insurance or discount cards. “More than a 3-month supply” marks packs from abroad that last more than 92 days at the usual dose. Under its personal importation policy, the FDA has long used enforcement discretion for some personal-use shipments, generally no more than a three-month supply; see our guide to buying from Canada before you order. “Fee not published” means the pharmacy doesn’t show its shipping fee before checkout, so that row’s total is the medicine price only.

What is Dilantin used for?
Dilantin (phenytoin) is an anticonvulsant, a medicine that helps prevent seizures. According to its FDA label (DailyMed), it is used for:
- Treating tonic-clonic (grand mal) seizures.
- Treating psychomotor (temporal lobe) seizures.
- Preventing and treating seizures that happen during or after brain surgery.
Dilantin comes as 30 mg and 100 mg extended capsules. The label's adult starting dose is one 100 mg capsule three times a day; for most adults the maintenance dose is one capsule three or four times a day, and some people whose seizures are controlled on 300 mg a day can take it once a day. Doses are adjusted to each person. Like other seizure medicines, the label warns about suicidal thoughts or behavior and about serious skin reactions. The capsules have no boxed warning. Your prescriber decides which medicine is right for you.
Is it safe to order Dilantin from Canada?
Many Americans do, but U.S. law and customs rules apply, and for Dilantin, compare the U.S. price of FDA-approved generic phenytoin before you order. Federal law generally doesn't allow individuals to import prescription drugs, though under its personal importation policy the FDA has long used enforcement discretion for some personal-use shipments, generally no more than a three-month supply (FDA). Congress has said enforcement against individuals should focus on imports that pose a significant threat to public health (Federal Food, Drug, and Cosmetic Act section 804(j)(1), 21 U.S.C. 384(j)(1)). You need a prescription from your doctor. New U.S. Customs rules for mailed orders start January 20, 2027. In Canada, Dilantin 30 mg and 100 mg capsules are sold under the same name by BGP Pharma, a Viatris company (Health Canada).

In the Texas 2026 drug price filing, a bottle of 100 generic phenytoin 100 mg extended capsules lists at $24.75 from Taro and $33.81 from Aurobindo. These are list prices (the maker's wholesale price before discounts); what a pharmacy charges can differ, so ask your pharmacist.
Is there a Dilantin coupon or savings card?
eDrugSearch doesn't offer coupons of its own. FDA-approved generic phenytoin is sold in the U.S.; ask your pharmacist for its cash price. If you have Medicare and limited income, Extra Help can lower what you pay for prescriptions.
How much does Dilantin cost with Medicare?
It depends on your Part D plan's drug list. In 2026, Part D deductibles are capped at $615 and out-of-pocket costs for covered drugs at $2,100 a year. People with limited income can apply for Extra Help.
How does this page compare Dilantin prices?
Per capsule, with each pack listed the way the pharmacy sells it. Doses differ from person to person: the FDA label's adult starting dose is one 100 mg capsule three times a day, and most adults take 3 or 4 capsules a day. Your prescriber sets your dose.
Is Dilantin sold in Canada?
Yes. Health Canada lists Dilantin 30 mg and 100 mg capsules as marketed by BGP Pharma, a Viatris company. Packs made for other countries are not FDA-approved. The price table shows each pack's country.
