I had a severe upper respiratory infection and regular well known antibiotics wouldn't kick it. I went back to the physician who prescribed Avelox. Within less than 2 minutes of taking the first pill out of the bottle I started getting sensations of bee's stinging my tongue everywhere and my lips were tight, purple and swollen. Within just minutes I started having a hard time breathing and the whites of my eyes were really bloody. Next thing I knew I could literally feel and hear my heart beat in my ears and everything sounded like I was in a tunnel. Within 5 minutes of taking the pill an ambulance was called and by the time they arrived my blood pressure was 70/16 with over 240 pulse.
When I got to the ER they said I wasn't the only one with the same issue to this drug and 3 were within the week prior to my being there. When I said I had SVT Supra Ventricular Tachycardia the doctor said people with SA Node (Natural pace maker of the heart) issues which control the magnetic aspect of your heart biting it sends something in there to screw it up and make it a big mess. I wouldn't suggest this med to anyone as I did some other research on it through the web and their reports from the FDA and there were some pretty NASTY side and long term effects of it.
Needless to say; since this happened I've developed a panic disorder and my nervous system isn't working correctly. Again; be careful what you take.
