A method of making prefilled syringes, the method comprising the steps of: displacing a succession of syringes along a conveyor path from a supply station successively through a marking station, a filling station, and to a downstream packing station; permanently marking the syringes in the marking station with machine-readable data identifying the medicament to be put in the empty syringe at the filling station; scanning the syringes downstream of the marking station and upstream of the filling station and removing from the conveyor path any syringe whose data is not readable; filling each of the syringes with a predetermined dose of a medicament in the filling station; and scanning the syringes downstream of the filling station and upstream of the packing station and removing from the conveyor path any syringe whose data does not correspond to the medicament filled into the syringe at the filling station.
