Why is this medication prescribed?
Dofetilide is used to treat irregular heartbeats. It improves your heart rhythm by relaxing an overactive heart.
This medication is sometimes prescribed for other uses; ask your doctor or pharmacist for more information.
How should this medicine be used?
Dofetilide comes as a capsule to take by mouth. It is usually taken twice a day. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take dofetilide exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor. Do not take a double dose.
Dofetilide controls abnormal heart rhythms but does not cure them. Continue to take dofetilide even if you feel well. Do not stop taking dofetilide without talking to your doctor.
What special precautions should I follow?
