I've been on Ampyra since November 2016. I am also on Aubagio. I have RRMS and thankfully, other than episodes, I am fairly functionally and hope to stay that way as long as this 62 year old body allows.
I was shocked by the quick turnaround in my body once I started Ampyra. For years, I have been unsteady, had trouble walking, and was stuck driving a van because I had trouble/pain even getting into a Kia Soul. So by December of 2016, I was helping to chop ice on our gravel driveway, walking with a lot less issue or pain and was able to lease a Kia Forte since I could get in and out of it with no pain or discomfort. It was an amazing Christmas gift to my body! My neurologist was thrilled.
Then by June of 2017, the Ampyra was not working as well. I made a 50-75% degradation from the progression I had made in December. I even asked the doctor if he could increase the dosage. Nope, can't. Bad enough having to go through a specialty pharmacy, but to lose effectiveness??
As my UPMC rep explained, that is the cold time of the year (ah, no fooling!), so it worked better because it was cool and dry. Yeah, it's been hot here. AC is cranking everywhere and cool towels are used, especially when cooking. I can't afford a cooling vest.
I'm very overweight, so I thought it was due to that, but I doubt that since it worked well when I started taking it. Anyone have any suggestions? I'm having an episode now with pain and walking, and as good as my chiropractor is, I feel I am fighting a losing fight.
