I need to get off trazadone , The pharmacists said it is most likely what is giving me the rapid heartbeat. I am on paxil too , he said those together could cause it. I got off the azithromycin because of the ringing in my ears. The paxil is working for my anxiety. When I get up in the morning I can feel and hear my heartbeat in my ears, and when i cough hard or do yard work. My CF doc wont let me take ambien or anything like that she said it suppresses the respiratory system and I don't want that.
