A liquid medicine dispensing device that dispenses liquid medicine by discharging one or more kinds of liquid medicine from an original drug vial into a prescription bottle, comprising: a rotary unit that rotates while holding a plurality of original drug vials that are arranged in a predetermined direction to invert the plurality of original drug vials together with rotation thereof; a discharge nozzle connected to each original drug vial; a discharge valve capable of opening and closing that is provided in each discharge nozzle; a conveyance mechanism that conveys a prescription bottle in a space on an underside of the rotary unit; detection means that detects a liquid medicine amount discharged into the prescription bottle; and control means that controls driving of the rotary unit, the discharge valves, and the conveyance mechanism, wherein the control means rotates the rotary unit to invert an original drug vial to be discharged until at least liquid medicine discharge begins and also drives the conveyance mechanism to move the prescription bottle to a position directly below the original drug vial to be discharged, and thereafter opens a discharge valve corresponding to the original drug vial to be discharged until a detection value at the detection means reaches a target value, to thereby cause a liquid medicine to be discharged.
