This little plastic item makes giving an injection a whole lot easier. I’ve never used an autoinject as I started this medication in 1993 and they didn’t yet exist for Copaxone. (then Cop I) Since these syringes were released with the tiny little finger supports this collar makes a huge difference in getting more control of the injection process. I got mine at the Shared Solutions site for free, although when I went back there to see if they are still offered I couldn’t find them. I have a few extras if anyone needs one. Drop me a note and let me know. If you aren’t doing an autoinject these collars make a big difference.
