Escitalopram Side Effects and Management

Introduction to Escitalopram Side Effects

The American Academy of Child and Adolescent Psychiatry recommends that citalopram/escitalopram should not exceed 40 mg/day in adults or 20 mg/day in adults over 60 years due to risk of Torsade de Pointes, ventricular tachycardia, and sudden death 3, 4, 5
The American Family Physician reports that gastrointestinal bleeding risk increases (OR 1.2-1.5) with SSRIs and SNRIs, and escitalopram has a dose-dependent risk of QT interval prolongation, particularly at 20 mg/day doses 1, 2

The American Academy of Child and Adolescent Psychiatry states that escitalopram has a dose-dependent risk of QT interval prolongation, particularly at 20 mg/day doses, and ECG monitoring is recommended in patients with cardiac risk factors or on higher doses 1, 2
The American Family Physician notes that citalopram/escitalopram should not exceed 40 mg/day in adults or 20 mg/day in adults over 60 years due to risk of Torsade de Pointes, ventricular tachycardia, and sudden death 3, 4, 5

The Journal of the American Academy of Child and Adolescent Psychiatry reports that serotonin syndrome develops within 24-48 hours when combining serotonergic medications, and is characterized by mental status changes, neuromuscular hyperactivity, and autonomic hyperactivity 4, 5, 6
The American Academy of Child and Adolescent Psychiatry recommends that escitalopram is contraindicated with MAOIs and requires caution when combining with other serotonergic drugs 3, 4, 5

The Journal of the American Academy of Child and Adolescent Psychiatry notes that abnormal bleeding can occur, especially with concomitant aspirin or NSAIDs, and rare bleeding events include ecchymosis, hematoma, epistaxis, petechiae, and hemorrhage 5
The American Family Physician reports that gastrointestinal bleeding risk increases (OR 1.2-1.5) with SSRIs and SNRIs 1

The American Family Physician states that age-related risk of suicidality is slightly increased in adults 18-24 years (OR 2.30), neutral in adults 25-64 years, and protective in adults ≥65 years (OR 0.06) 1
The American Family Physician notes that risk of suicidality is highest within 1-2 months of initiation or dose increase 1

The American Family Physician reports that hyponatremia occurs in 0.5-12% of older adults, with an OR of 3.3 for SSRIs compared to other drug classes, and typically develops within the first month of treatment 1

The Journal of the American Academy of Child and Adolescent Psychiatry recommends that escitalopram should be tapered over 10-14 days to minimize withdrawal symptoms, which include dizziness, fatigue, lethargy, and anxiety 4, 5, 2

The Pediatrics journal notes that third-trimester SSRI exposure causes neonatal adaptation syndrome, characterized by continuous crying, irritability, and jitteriness, with an onset ranging from hours to days after birth 8, 9
The American Family Physician reports that escitalopram transfers into breast milk in low concentrations, and infant plasma levels are typically undetectable 1

The Journal of the American Academy of Child and Adolescent Psychiatry states that escitalopram has the least effect on CYP450 isoenzymes compared to other SSRIs, resulting in lower propensity for drug interactions 3, 4, 5
The Journal of the American Academy of Dermatology notes that strong CYP450 inducers may decrease efficacy, while ritonavir does not affect escitalopram pharmacokinetics 7

The Praxis Medical Insights recommends starting with lower doses (10 mg/day) and gradually titrating to minimize gastrointestinal and CNS side effects, and taking medication at bedtime if daytime dizziness is problematic 2
The Journal of the American Academy of Child and Adolescent Psychiatry notes that anxiety or agitation can occur initially, making it advisable to start with a subtherapeutic "test" dose 3, 4
