What is the most important information I should know about ibutilide?

If possible, tell your doctor if you have taken a heart rhythm medication within the past 4 hours before receiving ibutilide.

In some cases, your heart rhythm problem can occur again or get worse even after you are treated with ibutilide. This may be more likely if you have other problems such as congestive heart failure. However, every effort will be made to quickly treat any additional heart rhythm problems you may have.

During your treatment with ibutilide, you will be watched closely with heart monitoring equipment so that any further problems can be treated quickly. Cardiac emergency equipment will also be kept nearby in case it is needed to treat you.
