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.

Diacomit coupons and savings programs

How do you pay?

We show the programs that usually fit, cheapest first where we know the price. Private insurance means a plan through work or one you buy yourself. Programs set their own rules, so check the terms before you count on one. We don't save this choice.

eDrugSearch does not offer its own Diacomit coupons. eDrugSearch has no coupons of its own. If you have Medicare, these two programs can help with the cost of Diacomit:

  • Medicare Extra Help: if you have Medicare and limited income, Extra Help lowers what you pay for prescriptions. (Social Security)
  • Medicare Prescription Payment Plan: a free Medicare option that spreads your drug costs into monthly payments across the year. It doesn't lower the total, but it can make costs easier to manage. (Medicare.gov)

What is Diacomit used for?

Diacomit (stiripentol) is an anti-seizure medicine. According to its FDA label (DailyMed), it is used:

  • To treat seizures caused by Dravet syndrome in people 6 months and older who weigh at least 7 kg (15 lb) and are also taking clobazam.

The label's dose is 50 mg per kg of body weight a day, split into 2 or 3 doses. The label says the capsules are swallowed whole with a glass of water during a meal and are not opened. The label says there's no data supporting Diacomit on its own for Dravet syndrome, and that dose changes are made gradually. Your prescriber decides which medicine is right for you.

Is it safe to order Diacomit from Canada?

Many Americans do, but U.S. law and customs rules apply, and for Diacomit, seizure medicines need a steady supply, so plan around shipping times and check your insurance first. 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. Health Canada lists Diacomit 250 mg and 500 mg capsules from Biocodex as marketed (Health Canada Drug Product Database, checked 2026-11-14).
