Topamax and allergic reaction

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.

Hey there! I haven't checked in for a few months, but everything has been going so well that I haven't had time! I thought that I would let you all know that I have now been on Topamax (100mg) for almost 1 year, and the side effects have leveled off almost competely. I lost 60 pounds in total, but the weight loss seems to have minimialized...I still lose a little each month, but I do have to work at it now like the rest of the general public! The hyper feeling has gone away, and I am able to sleep better too. The short term memory loss is getting better (I do have my moments!) but I practice my "words" by doing crossword puzzles! I can even enjoy a glass of wine now and then!

I hope this helps everyone just starting out with Topamax...I really had a tough go for the first few months and almost gave it up, even though it was working on the migraines!

I just had one question for anyone...I am experiencing a strange "post nasal drip" that I am hoping is not caused by an allergic reaction to the Topamax (it started a couple of months after I started the Topamax). Does anyone else have this side effect too?
