I take Ampyra 10mg x 2 per day. It has significantly improved my walking. I am at what I was about 5 years ago. So, it has been very good for me. No side effects, but I never have many side effects from Medications. I look for it to keep making me better in the future.

It is very expensive, $14,000 per year, but the Insurance will in most cases approve it since it will most likely reduce future Medical expenses. And it is the only Medication for MS caused problems.
