Supraventricular Tachycardia
"I have been on Tambacor for 7 years now and in the past 2 years I have been having dizzy spells, almost blackout, panic attacks for no reason, breathing problems out of the blue, eyes are blurring up more and more each year, no energy, weak muscles and not for lack of trying I just can&#039;t get them to tone up so I consider myself weak. My tummy gets upset ringing in the ears and the most annoying other than the dizziness is the low blood pressure it just drops so times!  These are all symptoms for this drug. I was in denial for a long time as these side effects were minimal and just became worse . I&#039;m  not on any other drug. I&#039;ll have to go off it but what&#039;s next??"
