I only lasted on copaxone for avout 5 and a half months. Had the injection site reastions that others have mentioned. Baseball size welts that hurt a lot for a few dyas and then itched like crazy for seveal days. I quit because I experienced several immediate post injection reactions. Sfopped taking about 6 in that time period, I had 2 in one week and my neiro said enough. After the reacions I also experienced a fever for several hours. I also had allergic reactions to betaseron and tysabri. I have been dx for over 9 years and was only on dmd's the first year. MS symptoms are stable.
