Effectiveness
How Tikosyn Affects PatientsDofetilide is a drug used to treat abnormal heart rhythms. It works by blocking a certain potassium channel, thus slowing down the rate of the heart. It does not affect sodium channels or the adrenergic alpha or beta receptors.
How Tikosyn works in the bodyDofetilide works by blocking potassium channels in the heart. This makes it harder for electrical signals to move through the heart, which prevents the heartbeat from becoming too fast. It also prolongs the amount of time it takes for electrical signals to move through accessory pathways in the heart.

Tikosyn Reviews: What are patients saying about Tikosyn?
5Patient Review
6/28/2016 After numerous failed attempts at other treatments, this drug finally did the trick. Within moments of taking the pill, I was back in rhythm and have been for four months now. Fingers crossed that it keeps working!
5Patient Review
3/30/2017 After years of dealing with Afib and flutter, I was really struggling. Cardizem plus Metropalol used to help, but it also dangerously low levels. Flecanaide didn't have any effect. Xaralto finally did the trick for me, though I had to go into the hospital for a cardioversion. But after that, I felt great again!
5Patient Review
3/14/2015 Tikosyn has been effective for two years for my chronic A-Fib. A troublesome side effect is the fatigue and brain fog. When I asked my cardiologist about this, he said this was the best solution for my A-Fib, but he was worried about my "brain." Does long term use of Tikosyn cause Dementia or Alzhimers?
5Patient Review
6/14/2020 The goal of this treatment was to stop my heart completely. With the pacemaker and defibrillator, it's been successful in controlling the sarcoidosis in my heart.
5Patient Review
7/18/2021 I've tried four ablations already and none of them worked for me. This medication, however, has been a total game-changer. I don't think I've experienced any negative side effects, and it's been two years since I started taking it.
