Buying from a pharmacy outside the U.S.? Read Is it safe to order Zarontin from Canada?
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 12, 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. “Fee not published” means the pharmacy doesn’t show its shipping fee before checkout, so that row’s total is the medicine price only.

Other ways to pay, useful if you have insurance or Medicare:
- TrumpRx.gov: TrumpRx.gov lists 120 brand Zarontin 250 mg capsules for $81.60 (original price $163.20), checked November 12, 2026. You print or save a coupon and show it at a retail pharmacy that carries Zarontin. It can't be used with Medicare or Medicaid coverage, and a cash purchase won't count toward a Medicare plan's deductible or the $2,100 yearly cap. With private insurance, ask your plan whether a cash purchase counts toward your deductible. (TrumpRx.gov)
We list these because they may save you money. No one pays us to include them. Prices and eligibility rules change, so confirm before you buy. Checked Nov 12, 2026.

What is Zarontin used for?
Zarontin is a seizure medicine (a succinimide anticonvulsant). According to its FDA label (DailyMed), it is used:
- To control absence (petit mal) seizures. It may be used with other seizure medicines when other types of seizures also occur.
The label's starting dose is 1 capsule (250 mg) a day for children 3 to 6 years old and 2 capsules (500 mg) a day for people 6 and older. After that, the dose is raised slowly, often by 250 mg every 4 to 7 days, until seizures are controlled; the best dose for most children is about 20 mg per kg of body weight a day. Doses above 1,500 mg a day need close supervision. Like other seizure medicines, it carries a warning about suicidal thoughts. Your prescriber decides which medicine is right for you.
Is it safe to order Zarontin from Canada?
Many Americans do, but U.S. law and customs rules apply, and for Zarontin, compare the U.S. prices of FDA-approved generic ethosuximide and the TrumpRx.gov coupon 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, Zarontin 250 mg capsules are sold by Searchlight Pharma, listed as marketed (Health Canada, checked 2026-11-12).
