Sorry to hear that. I have taken the Amantadine. I still take the Mepron and Azithromycin. For me, it was the Amantadine and Azithromycin combo together that caused so many side effects. My head felt way off and I was disoriented and dizzy. It literally took 2 months to get that stuff out of my system and me feeling halfway normal again. Is that a new med for you? I don't notice to much with the Mepron and Azithromycin together...except after a month or so on it, I feel like I've been overloaded and take a break from it for a few days then resume.
I would seriously consider the Amantadine as the cause for your dizziness. There are other meds that could be given to you in place of the Amantadine.
