The invention is directed to a drug delivery device (1) comprising a housing (7) retaining a primary drug delivery assembly (16) and a secondary drug delivery assembly (17). The secondary drug delivery assembly (17) comprises a secondary dose setting mechanism with a biasing member adapted to reset the secondary dose setting mechanism in a resetting movement (65). An actuator (34) is movable relative to the housing (7) and comprises a first engagement section (55) configured to engage a second engagement section (53) provided by an actuation collar (37) such that an actuation movement (63) of the actuator (34) is transferred to the actuation collar (37). A setting element (35) is movable between a first position and a second position and is connected to the secondary dose setting mechanism such that during the resetting movement (65) of the secondary dose setting mechanism, the setting element (35) is moved from the second position into the first position, wherein the setting element (35) is configured to drive the actuation collar (37) out of engagement with the actuator (34) when being moved from the second position into the first position.Linvention concerne un dispositif (1) dadministration de médicament comprenant un logement (7) contenant un ensemble (16) dadministration dun médicament principal et un ensemble (17) dadministration dun médicament auxiliaire.
