I have had trouble breathing with Topamax. I have been on the med twice. The first time, my doctor suspected that the mix of Allegra D and the Topamax caused an allergic reaction, the feeling of someone sitting on my chest and a breathing difficulty. So, she told me to stop both of them cold turkey. I did. The side effects went away, I felt better after 3 days. My migraines came back so I went to see a neurologist who wanted to try the Topamax again. I agreed to try it. I feel that familiar breathing problem, but not as bad. This time around, I think it is triggering asthma attacks which I have never had before. Someone was cutting the grass next door and when I breathed it in, I couldn't breathe. I had to shut the windows quickly and I coughed until I caught my breath. There was a natural gas smell in my apartment bldg. last week, I was in the hall for 4 mins. and had to leave quickly because it took my breath away. It took me 20 mins. to stop coughing. When I smell nail polish or the remover, etc. now, I can't breathe. I left the house yesterday and was panting while driving. I can't walk on my new treadmill without breathing hard. That never used to happen. Other side effects include pain behind my eye when I go out in the sun, my lips burn every time I go out in the sun, so do my ears, tingling in my thumbs and feet that can be painful, allergic to my cats now (breaking out in hives), and just not quick with the mind like I used to be. I know I shouldn't be driving. I've only been taking it for 6 weeks.
