A spacer may improve the effectiveness of medication delivery by an inhaler. The spacer may be configured to store the inhaler to improve compactness and/or portability of the spacer and inhaler. The inhaler may be coupled to a retaining device, inhaler container, and/or the like that restricts movement of the inhaler to predetermined positions and/or orientations. A user may be able to transition the inhaler between a stored position and an active position by moving the inhaler translationally and/or rotationally. The inhaler may be able to remain coupled to the retaining device and/or inhaler container, and the retaining device and/or inhaler container may be able to remain coupled to the spacer during transition from the stored position to the active position. The spacer may be sized to fit in a pants pocket in an embodiment.
