Clomipramine may cause a condition that affects the heart rhythm (QT prolongation).

Before using clomipramine, tell your doctor or pharmacist if you have any of the following conditions: certain heart problems (heart failure, slow heartbeat, QT prolongation in the EKG), family history of certain heart problems (QT prolongation in the EKG, sudden cardiac death).

Low levels of potassium or magnesium in the blood may also increase your risk of QT prolongation.

Talk to your doctor about using clomipramine safely.
