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.

Form & strength	Pharmacy cost	Unit	Type
NITROFURANTOIN 25 MG/5 ML SUSP	$1.72	per mL	Generic
NITROFURANTOIN MCR 100 MG CAP	$0.23	per tablet/unit	Generic
NITROFURANTOIN MCR 25 MG CAP	$1.78	per tablet/unit	Generic
NITROFURANTOIN MCR 50 MG CAP	$0.16	per tablet/unit	Generic
NITROFURANTOIN MONO-MCR 100 MG	$0.30	per tablet/unit	Generic

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