Dofetilide

Drug Details

Dofetilide, marketed under the brand name Tikosyn, is an antiarrhythmic medication prescribed to treat and prevent specific types of irregular heartbeats, such as atrial fibrillation and atrial flutter. This medication helps restore and maintain a normal heart rhythm by blocking potassium channels, which are crucial in regulating the heart's electrical signals. By doing so, dofetilide reduces the risk of complications like blood clots, which can lead to heart attacks or strokes. Although effective, dofetilide requires careful monitoring, especially during the initial treatment phase, which involves a minimum three-day hospital stay to ensure the dosage is safe. It is important to note that dofetilide can interact with other medications, including certain diuretics and antiarrhythmics, and may cause side effects such as headaches, chest pain, and dizziness. Always consult your healthcare provider for personalized advice before starting or adjusting your medication regimen.
