Atrial Fibrillation
"Flecainide works for me but caused symptoms that mimicked MS. I was put on Flecainide in October 2009 for Atrial fibrillation. Started having dizzy spells and vertigo soon after. Then started getting migraines (never had it before in my life) and seeing flashing lights. Ringing in the right ear started in November. Then by February 2010 episodes of incontinence, slurred speeches, confusion, difficulty focusing on conversations, stumbling, falling, tingling in finger tips, dropping pens, dishes, anything I held. Feared I had multiple sclerosis. After tests for MS - all negative - I went to my cardiologist and asked if Flecainide may be the cause. He said not likely but lets stop it and see. Four weeks after stopping, all symptoms cleared."
