A cap-fit differentiation means for use with a medication or drug delivery device (100, 206) is described. The cap (106,200) includes at least one first coding feature located on a surface (204) of the cap (106, 200), the at least one coding feature configured to interact with at least one second coding feature located on the drug delivery device (100, 206). When the first and second coding features interact, feedback is provided to a user. The feedback may include tactile and/or audible feedback. The second coding feature may alternatively be located on the cartridge (120) or cartridge holder (104). |
