I'm taking both copaxone and LDN. My neurologist prescribed LDN when I requested it. He has other patients also taking it. I go to St. Luke's Neuroscience Center in Milwaukee, WI. My neurologist is Bhupendra Khatri. He and the Center are nationally known. ( He is one of the major researchers for plasma pharesis.) I haven't had any real problems with the combination. I think that the LDN has helped my fatigue a little and also has improved my balance and walking ability.
One word of caution: My local compounding pharmacy attempted to charge me $65.00 until I told them that LDN was available on the internet for $25. They reduced their price.
Good luck to you.
