Buying from a pharmacy outside the U.S.? Read Is it safe to order Fidaxomicin from Canada?
Course cost = 20 tablets for one 10-day course, bought as one order of whole packs with one shipping fee. Course cost is worked out from each pharmacy's real order size so different pack sizes compare fairly. Orders are kept within a 3-month supply (92 days); a pack that is larger than that is marked and not used for the lowest price at the top of this page. Prices checked Nov 11, 2026 on each pharmacy's website, in U.S. dollars. Savings compare with the U.S. list price. 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. Price is the pharmacy's own price for one pack, as shown on its website (converted to U.S. dollars when it prices in Canadian dollars). Delivery is the pharmacy's own estimate for the shipping option shown, not a promise; some pharmacies count from when they receive your prescription or ship the order. Total = the packs needed + shipping. When those packs don't add up to exactly 90 days, the row shows what that order costs and, under it, what it works out to for one 10-day course; we sort by the 90-day amount so pack sizes compare fairly. 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, for whole fills, 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.

Savings programs from the maker
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 Fidaxomicin coupons. Merck's Patient Assistance Program is for brand Dificid only (see the brand page). These programs can lower what you pay for generic fidaxomicin:
- 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)
- Costco Pharmacy member prices: Costco publishes member prices for many prescriptions, for people with a Costco membership. Non-members can also use Costco pharmacies and pay the regular cash price. Member prices can't be used with insurance, Medicare or Medicaid claims. (Costco Pharmacy)
- Amazon Pharmacy Prime and RxPass: Amazon Pharmacy offers Prime members discounts on many prescriptions, and RxPass, for Prime members, covers a set list of generics for a flat monthly fee. Prime is not required to use Amazon Pharmacy. Prime savings have limits for people with Medicare, Medicaid or Tricare, and RxPass is not open to people with Medicaid or CHIP. (Amazon Pharmacy)
- Discount cards: Discount cards (for example GoodRx or SingleCare) may lower the price at local pharmacies; prices vary by pharmacy and ZIP code.
When people choose brand Dificid
Some people get brand Dificid instead of generic fidaxomicin. Common reasons:
- A prescription marked “dispense as written” (or “brand medically necessary”) tells the pharmacy to fill brand Dificid, not a generic. State laws set the rules for generic substitution.
- Merck gives free brand Dificid to eligible U.S. residents with no prescription coverage and household income within its limits (Merck Helps). Call 1-800-727-5400 to check.
- Some insurance and Medicare drug plans cover the brand and the generic at different copays, or cover only one of them. Your plan's drug list shows which.
Your prescriber decides which medicine is right for you.

What is Fidaxomicin used for?
Fidaxomicin is a macrolide antibiotic, the same medicine as in Dificid. According to the Dificid FDA label (prescribing information), it is used:
- To treat diarrhea caused by Clostridioides difficile (C. diff) in adults and children 6 months and older.
The label's usual adult dose is one 200 mg tablet twice a day for 10 days (20 tablets). The label says it should be used only for infections proven or strongly suspected to be caused by C. diff, because it is not expected to work for other infections. It has no boxed warning. Check the label that comes with your medicine. Your prescriber decides which medicine is right for you.
Is it safe to order Fidaxomicin from Canada?
Many Americans do, but U.S. law and customs rules apply. 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 declared in FD&C Act 804(j)(1), 21 U.S.C. 384(j)(1), that enforcement against individuals should focus on imports posing a significant threat to public health. You need a prescription from your doctor. New U.S. Customs rules for mailed orders start January 20, 2027. We found no generic fidaxomicin at licensed pharmacies abroad, and FDA-approved generics are sold in the U.S.
