FOSFOMYCIN 3 GM SACHET

What it is

FOSFOMYCIN 3 GM SACHET is how the CMS NADAC file names this product. The FDA NDC Directory lists it as “fosfomycin tromethamine” and “granules for oral solution”, as its NDCs’ listings variously write the nonproprietary name.

FDA gives its dosage form as “granule, for solution”, “granule” and “powder” and its route as oral.

FDA lists 7 labelers (the companies named on the label) for its NDCs, among them Aurobindo Pharma Limited, Amneal Pharmaceuticals NY LLC and Ascend Laboratories, LLC.

FDA lists no Established Pharmacologic Class for it.

The NADAC file of 2026-10-14 prices it under 11 NDCs (National Drug Codes); the FDA directory lists 8 of them.

NADAC classes it as a generic drug (rate-setting class G), and does not mark it as sold over the counter.

What to ask at the counter

None of these figures is your price: what you pay depends on your pharmacy, your insurance, coupons and discounts.

• What is your cash price for 1 unit (EA)? Is it lower than what I would pay through my insurance?
• If you have Medicare Part D: what is my plan’s copay or coinsurance for it? The Part D average on this page is not what you pay.
• These are questions about price, not medical advice. Do not change or stop a medicine without talking to your prescriber or pharmacist.
