Abstract
A syringe is described with a plunger assembly that is adapted to have a dispensing stroke sized to dispense a fluid therapeutic product from the syringe without dispensing any air or headspace. The syringe includes a plunger rod having a stop feature that stops a dispensing stroke of the plunger rod at a distance corresponding to a level of air or headspace within the syringe avoiding additional air dispensing steps from a healthcare provider.
