A cartridge for a medication dispensing device which includes multiple septums. The cartridge includes a body and an axially shiftable piston in fluid-tight engagement with an interior surface of the body. The first septum covers a dispensing port that opens to an interior hollow of the body at a proximal location. The second septum covers a filling port that opens to the interior hollow. The first septum is arranged to be engaged by a dispensing conduit moving generally perpendicular to the axial direction for fluidly communicating with the interior hollow during a dispensing operation of the device. The second septum is arranged to be engaged by a filling conduit for fluidly communicating with the interior hollow during filling of the cartridge.
