Nitrofurantoin: what pharmacies actually pay

Prices below are the National Average Drug Acquisition Cost (NADAC) — the federal government's weekly survey of what pharmacies actually pay their wholesalers, as of 07/22/2026. Your pharmacy's cash price includes their markup and dispensing cost, so it will be higher — but if it's many times this number, that's a signal to shop around.

NITROFURANTOIN MCR 50 MG CAP$0.16per tablet/unitGeneric
NITROFURANTOIN MONO-MCR 100 MG$0.30per tablet/unitGeneric

Rough math: a typical 30-day supply of one tablet/day equals 30× the per-unit cost.
