Abstract
A drug delivery device includes a piston rod which extends along a longitudinal axis of the drug delivery device, wherein the piston rod is adapted to apply an axial load in the distal direction to a cartridge bung in order to dispense a medicament contained in the cartridge. In order to improve the convenience of the injection process and to mitigate the risk of underdosing due to a blocked needle a cartridge bung load indicator is provided, located at the distal end of the piston rod and adapted to abut against the cartridge bung, wherein the cartridge bung load indicator comprises an indicator element that audibly, tangibly and/or visually indicates a load state of the piston rod to the user.
