An injection device includes a lower housing, a needle guard and an upper housing. With the upper housing in a pre-use position and the needle guard in a first position, an abutment body of an arm of the upper housing abuts a catch of the lower housing, preventing the upper housing from moving distally relative to the lower housing toward a dispensed position. Proximal movement of the needle guard from the first position to a second position thereof causes proximal movement of a camming ramp of a leg of the needle guard with respect to the catch and the abutment body such that the camming ramp engages the arm, thereby deflecting the abutment body radially outwardly by a distance sufficient to allow the abutment body to pass radially outside of the catch, and, in turn, permits the distal movement of the upper housing into the dispensed position of the upper housing.

A method of detecting and/or tracking use of a drug delivery device is disclosed. The drug delivery device includes a machine readable code and a visual indicator, and has pre-use and used states, such that use of the drug delivery device triggers a transition from the pre-use to the used state. The visual indicator has a first state when the drug delivery device is in the pre-use state and a different second state when the drug delivery device is in the used state. The method includes enabling a user device having an image sensor to capture an image of the drug delivery device, determining, by the user device processor from the captured image, whether the visual indicator of the drug delivery device is in the second state, and obtaining, by the processor, information from the machine readable code when the visual indicator is determined to be in the second state.
