Dofetilide for Arrhythmia "I have been taking Tikosyn for 5 weeks. It did not kick in until they did a cardioversion on me. I am still having high blood pressure and high heart rate, as well as skipped beats. I have a rash and itching that is very bothersome. But other than that, I am doing well. I feel good, but I just wish my blood pressure and heart rate would go back to normal."

Dofetilide for Arrhythmia "Experienced CHF in 2010 induced by hypothyroidism, which I had detected 30 years earlier, but doctors couldn't confirm because of outdated TSH standards; also had hypotension and hypoglycemia, which were again medically unconfirmed until 2010 CHF with EF of 13%. Defibrillator implanted in 2010. Put on dofetilide in 2014 by new doctors because other docs had ignored effects of amiodarone on thyroid medication plus amiodarone toxicity. In 2015 had tachycardia of 168; another new doc said dofetilide should have worked, recommended ablation, which was subsequently done. Experienced crippling fatigue; I phased out dofetilide a year later, no arrhythmias, energy returning plus clear thinking. Found ablation effective, dofetilide ineffective plus energy crippling."

Dofetilide for Arrhythmia "I have been on Tikosyn for 6 months. The first 4 months were difficult as there were lots of skips and bumps in between episodes of 1-2 per week. Though the times in arrhythmia were getting much shorter. I still feel as though my condition is improving overall, as there are not as many symptoms as before I was taking it. Hope it just keeps getting better."

Dofetilide for Arrhythmia "I had 9 episodes of arrhythmia 2 hrs and 15 mins after taking. This took 1 hr and 22 mins. I flatlined 7 times, corrected once with CPR, the other six I was paddled. It was my first dose. They were watching, it was pretty bad! Now you know."

Dofetilide for Arrhythmia "61-y old man with paroxysmal Afib previously controlled by Flecainide. Backfired and made Afib much worse during my 3-day hospital monitoring. Tikosyn (500 mcg bid) had a major diuretic effect on me and I went into bouts of Afib up to 11 h long with severe tachycardia 160 bpm."
