Approximately 1 1/2 years ago I was given Avelox for Bronchitis. I had taken the drug several times without any Side Effects. Within 15 minutes of taking that dose I got a flush that started at my toes and went up to my head in seconds. Then I started to itch and broke out in hives. At this point my mouth started to swell and I knew this was bad. At this point I called my doctor's office and told them I had an EPI Pen at home should I use it. The nurse told me to take a Benadryl and that she would check with the DR and call me back. She said if the reaction got worse to just call the squad and go to the ED. The nurse called me back and told me to use the EpiPen and if this didn't help to call 911. It was pretty scary.
