Has anyone experienced a generalised allergic reaction to their medication in the form of hives? I've been on Copaxone for 9 months and 2 months ago broke out in a really nasty case of hives. They cover my body from head to toe, come and go at random with varying degrees of severity, not to mention incredibly itchy. At first the neuro said it wasn't the Copaxone but changed his mind recently when he saw how bad they were. Apparently its a rare reaction but not unheard of. Has anyone else experienced it on Copaxone or any of the other drug therapies?
