Citalopram and escitalopram are associated with dose-dependent QT interval prolongation and should not be used in:
- patients with congenital long QT syndrome or
- known pre-existing QT interval prolongation combination with other medicines known to prolong the QT interval
ECG measurements should be considered for patients with cardiac disease, and electrolyte disturbances should be corrected before starting treatment.
