Ondansetron: 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
ONDANSETRON 4 MG/5 ML SOLUTION	$0.28	per mL	Generic
ONDANSETRON 4 MG/5 ML SOLUTION CUP	$0.28	per mL	Generic
ONDANSETRON 40 MG/20 ML VIAL	$0.17	per mL	Generic
ONDANSETRON HCL 4 MG TABLET	$0.06	per tablet/unit	Generic
ONDANSETRON HCL 4 MG/2 ML VIAL	$0.18	per mL	Generic
ONDANSETRON HCL 8 MG TABLET	$0.08	per tablet/unit	Generic
ONDANSETRON ODT 4 MG TABLET	$0.12	per tablet/unit	Generic
ONDANSETRON ODT 8 MG TABLET	$0.16	per tablet/unit	Generic

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