QT interval prolongation: Cases of QT interval prolongation and ventricular arrhythmia including Torsade de pointes can be observed predominantly in patients of female gender with hypokalemia or with pre-existing QT interval prolongation or other cardiac diseases (see Contraindications, Warnings, Precautions, Interactions, Overdose and Pharmacology under Actions).
Class effects: Increased risk of bone fractures can be observed in patients receiving SSRIs and TCAs. The mechanism leading to this risk is unknown.
Discontinuation symptoms seen when stopping treatment: Discontinuation of SSRIs/SNRIs (particularly when abrupt) commonly leads to discontinuation symptoms. Dizziness, sensory disturbances (including paraesthesia and electric shock sensations), sleep disturbances (including insomnia and intense dreams), agitation or anxiety, nausea and/or vomiting, tremor, confusion, sweating, headache, diarrhea, palpitations, emotional instability, irritability, and visual disturbances are the most common reactions. Generally these events are mild to moderate and are self-limiting; however, in some patients they may be severe and/or prolonged. It is therefore advised that when Escitalopram treatment is no longer required, gradual discontinuation by dose tapering should be carried out (see Dosage & Administration, Warnings and Precautions).
