A drug delivery device comprises a housing (2) and a piston rod (13) arranged in the housing. The piston rod (13) is adapted to be moved along an axial direction to dispense a fluid. A drive member (5) arranged in the housing (2) is operatively coupled to the piston rod (13) and adapted to set up a dose of fluid for dispense in response to a first movement. The drive member (5) is also adapted to move the piston rod (13) to dispense the dose in response to a second movement. The drug delivery device also comprises a pre-dispensing drive member (18) operatively coupled to the drive member (5) and the housing (2) and adapted to move at least the drive member (5) by a pre-dispensing distance between its first and second movement.
