Abstract: Described herein are methods and systems for operating a syringe-based drug delivery device to eject a dose of a fluid from a delivery conduit, such as a needle. The methods involve advancing a plunger rod of the syringe-based drug delivery device in an axial direction of the plunger rod from a start of dose position to an end of dose position. This advances a plunger stopper within a barrel of the syringe-based drug delivery device. The plunger stopper is compressed when the plunger rod first reaches the end of dose position. The difference between the start of dose position and the end of dose position accounts for compression of the plunger stopper caused by resistance of the fluid to ejection through the delivery conduit.
