Drug Interactions With Haloperidol (Cont.)

Haloperidol Interactions Explained

All of the above medications (except lithium) increase the risk of a dangerous, irregular heart rhythm (arrhythmia) called QT prolongation. Because haloperidol can also increase the risk of QT prolongation, it should generally not be combined with any of the above medications. There may be some situations in which taking haloperidol with the above medications may be appropriate, especially if your healthcare provider is closely monitoring your heart. Because this list does not contain all of the QT prolonging medications, it is important to tell your healthcare provider about any medication you are taking.
 
A few people who have taken haloperidol in combination with lithium have experienced dangerous side effects that have caused irreversible brain damage. If you are taking these two medications together, your healthcare provider should monitor you closely for any dangerous side effects.
