My husband was prescribed that on his second or third visit to his neurologist. He was also taking c/l. It didn't seem to make any difference for him, so given the possible side effects he stopped taking it. He didn't actually have any side effects, but it didn't seem worth while. I think his doctor was really premature in ordering that and then Amantadine so early in his diagnosis. He stopped that one as well, for the same reason.
