Copaxone took a YEAR to start working for me! Most patients "START" to show that its working in 6 months, and some can take up to 18 months to show stability.
Is this the only DMD you tried? Have you tried others? Copaxone is amazing, but you must give it time to work. Significant increase may throw you onto another DMD such as Betaseron, or Rebif, or even Ty.
Please know that you have a bunch of folks cheerleading for you, and praying with you.
hang in there.
