Avelox and asthma attack

I took avelox one time, about an hour after I took it I felt like I was having a horrible asthma attack, I couldn't breathe, I tried my inhaler but it was no help. Then I became so incredibly hot and started having these horrible stomach pains. I had to lay down on the bathroom floor they were so bad. I called my mom who rushed over to take me to the Emergency room which is a good thing because by the time we got there I was covered in hives and could not breath and this all started about an hour to an hour and a half after taking avelox.. This stuff is toxic and should be removed from the market immediately if not sooner.

My sister was prescribed Avelox on Tuesday, March 11, 2008. Within 15-20 minutes she began having breathing difficulties. Because she has asthma her initial thought was that she was having an asthma attack. She tried asthma treatment and it didn't help. She soon was unable to breath. Her husband called 911, they responded quickly but had to intubate her in the ambulance. They know that she was without oxygen to her brain for at least 3-5 minutes. This caused seizures that lasted 20 hours before I.C.U. could get them under control. Unfortunately it caused brain damage leaving her with no higher brain function (vegetative state). As she has worked in the medical field for over 14 years she did not wish to be kept alive by artificial means. On Tuesday, March 18, 2008 her ventilation tube and feeding tube were removed. It is now Thursday, March 20, 2008 and she is in a wonderful Hospice House awaiting her death.
She had taken the same class of antibiotic in the past with no reaction. Really not sure what caused this one. She was going through chemo for breast cancer, but had just finished and was scheduled to start her radiation treatment. Her chemo doctor told us that since her reaction, they have had another patient who went into anaphylactic shock after taking Avelox.
My sister is only 43 years old. This medication should be taken off the market.
