A medication administering device for automatically identifying a medication syringe and administering a correct medication. A microprocessor (20) of the medication administering device (1) identifies the color of a medication or a medication syringe on the basis of a reference value, determines the adequateness of the medication, and indicates the result of the determination by means of an LCD (10) or the like to the user. In step S4, the microprocessor (20) determines whether or not color data received from a color detecting unit (13) is within a reference value range. If the color data is within the reference value range, the microprocessor proceeds to step S5, otherwise proceeds to step S6. In step S6, the microprocessor (20) issues a message to the effect that the user needs to check the medication.
