ibutilide fumarate

Ibutilide (Corvert) is an antiarrhythmic medication. It works by attaching to certain receptors (proteins) in your heart that are responsible for controlling the rhythm of your heartbeat. When ibutilide (Corvert) attaches to these receptors, it slows down your heart rate.

Ibutilide (Corvert) is given as an injection through the veins (intravenously or IV) over 10 minutes by a healthcare provider in the hospital. Your provider will calculate the appropriate dose for you, since it depends on your body weight. If your irregular heart rhythm doesn't go away within 10 minutes after the first dose, your provider might give you another dose.

Possible side effects include nausea and headache. Additionally, since ibutilide (Corvert) works to control your heart rhythm, it can potentially cause or worsen irregular heart rhythms. One of these abnormal heart rhythms is called QT prolongation, which can be life-threatening. Because of this risk, your providers will have equipment and treatments readily available during and after your ibutilide (Corvert) injection. Your heart rhythm will be monitored continuously for at least 4 hours after receiving the medication. If your provider detects that you've developed a new irregular heart rhythm, they will treat it accordingly.
