Hi, ! While our members may not have mentioned experiencing side effects like yours while on Ampyra, both nausea and problems with balance/dizziness are listed as common side effects of the medication. Generally, many of the more common side effects diminish or go away as your body adjusts to the medication, but not always. I would definitely stay in communication with your doctor about these symptoms.
Hang in there and I hope Ampyra works for you AND that the side effects go away very soon!
Best, Erin, Team Member.
