Dofetilide, sold under the brand name Tikosyn, is a medication used to keep people with atrial fibrillation or atrial flutter in sinus rhythm. It is only indicated in those who have been in an abnormal rhythm for more than a week and have significant symptoms. It is taken by mouth.

Common side effects include headache, chest pain, and dizziness. Other side effects may include QT prolongation and potentially an increased risk of death. It should not be used in people with severe kidney problems. Safety in pregnancy is unclear. It is a class III antiarrhythmic agent.

Dofetilide was approved for medical use in the United States in 1999. While it was approved in Europe in 1999, this was withdrawn in 2004. In the United States it costs about 25 USD per month.
