Dose & administration There are different schools of thought regarding gentamicin dosing in neonates and tertiary dosing references vary in their dosing recommendations. Commonly accepted dosing regimens include both a gestational age based dosing approach as well as birth-weight based dosing approach. Doses range from 4-5mg/kg per dose administered every 24 to 48 hours with lower gestational ages requiring the higher weight based dosing and longer dosing interval than older gestational age infants. The NICE guidelines (UK) recommend 5 mg/kg every 36 hours as the starting dose.
