What Cordarone X is used for

Cordarone X is used to control a fast or irregular heart beat.

It works by lengthening the gap between one heart beat and the next, helping to bring the heart rate to a slower and more regular pace.

Cordarone X is not recommended for use in children.

Your doctor may have prescribed this medicine for another reason.

Ask your doctor or pharmacist if you have any questions about why this medicine has been prescribed for you.

To help prevent unwanted side effects, your doctor may need to perform the following tests, depending on the length of treatment with Cordarone X:

  • ECG

Take Cordarone X exactly as your doctor has prescribed.

Your doctor will monitor you very carefully for side effects. This will involve blood tests to check how well your liver and thyroid are functioning. It will also involve regular chest x-rays, ECGs and eye tests.
