Avelox I was prescribed Avelox for bronchitis on Thursday the 6th....not feeling better in 2-3 days fill the Rx. Talked to on call doc Sunday morning, was advised to begin to medicine, plenty of water and rest. As I have a known allergy to sulfa, I confirmed with the pharmacy the RX was okay then took my first dose Sunday evening. Within 30 minutes I had severe stomach cramps followed by sudden and explosive diarrhea. As I was trying to rationalize these symptoms I was hit (and I mean HIT) just as suddenly with racing heart, tingling lips, shortness of breath, tightness in my chest, light-headedness....at this point I yelled for my husband to call 911 before I passed out. As he came in the room, I was on the floor gasping for air...don't remember much in the following events. I know that he administered my epi-pen (I was to disoriented to even think of this**and I have had to carry it at all times for about 6 years due to other allergies) saved my life as my son says EMS/fire /police did not arrive for another 4-5 minutes. This experience scared us all! I have had meds case panic attacks in the past THAT IS NOT what I experienced at all!! This was a life threatening reaction...I agree with the CLASS ACTION SUIT as until reading your postings I could not figure out why 3 days later my stomach still hurts and although the coughing is better my chest still feels like someone is compressing it (I had a chest film to confirm the bronchitis had not progressed * confirmed clear yesterday) and my sleep is totally messed up. I would not wish this on anyone. Thanks for sharing as now I know what is going on.....ALL THIS FROM ONE DOSE......JUST ONE PILL......
