It includes a piston rod that operably engages with a piston of a cartridge to displace the piston in an axial distal direction. It includes a first dose indicating member that is rotatably supported on a longitudinal axis. It includes a second dose indicating member axially adjacent to the first dose indicating member and rotatably supported on the longitudinal axis. It includes a dose setting sleeve extending in an axial direction, rotatably engaged with the first dose indicating member and axially extending through the first dose indicating member to rotatably engage with the second dose indicating member.
