An object of this invention is to provide a drug solution container package, which can restrain degradation of a drug solution, proliferation of microbes, etc. accompanying the transmission of oxygen in a high degree while maintaining characteristics required of plastic drug solution containers such as heat resistance, impact resistance, pliability, transparency, and resistance against elution of plastic forming material, and to provide a method for manufacturing the drug solution container package. In the present invention, to achieve the above object, a drug solution is contained and sealed in a plastic drug solution container having an oxygen gas transmission rate (25°C, 60%RH) of not less than 200cm3/m2 · 24h · atm within twelve hours after being subject to steam sterilization or hot water sterilization, and having an oxygen gas transmission rate (25°C, 60%RH) of not more than 100cm3/m2·24h·atm when the oxygen gas transmission rate is in a steady state, and thereafter the plastic drug solution container is steam sterilized or hot water sterilized and then are contained and sealed along with an oxygen scavenger in an outer pouch having an oxygen barrier property.
