An automated medication preparation system including reconstitution of medication and its delivery to a syringe. An automated fluid delivery device that is movable in at least one direction and is adapted to perform at least one of the following operations: receiving and discharging diluent in a prescribed amount to reconstitute the medication in a drug vial; and aspirating and discharging reconstituted medication from the vial into the syringe. Further including a transfer device that includes a first section for piercing a septum of the vial and a second section for releasably mating with the fluid delivery device. The transfer device can remain within the vial for multiple uses without the need to repierce the septum. The transfer device has a first channel for carrying diluent or reconstituted medication and a second channel in fluid communication with a vent formed as part of the transfer device to permit airflow into the vial.
