Overdose Information
Overdose Symptoms:
- Dizziness
- Sweating
- Nausea
- Vomiting
- Tremor
- Somnolence
- Tachycardia
- Hypotension
- Arrhythmias (including QT prolongation, Torsade de Pointes)
- Seizures
- Coma
- Serotonin syndrome
What to Do:
Seek immediate medical attention. Call 911 or Poison Control at 1-800-222-1222. Treatment is generally supportive and symptomatic. Activated charcoal may be considered if ingested recently. Monitor cardiac rhythm and vital signs.
Drug Interactions
Contraindicated Interactions
- Monoamine Oxidase Inhibitors (MAOIs) (e.g., phenelzine, selegiline, linezolid, methylene blue) - risk of serotonin syndrome.
- Pimozide - risk of QT prolongation and cardiac arrhythmias.
Major Interactions
- Other serotonergic drugs (e.g., triptans, tricyclic antidepressants, fentanyl, lithium, tramadol, buspirone, tryptophan, St. John's Wort) - increased risk of serotonin syndrome.
- Drugs that prolong the QT interval (e.g., Class IA and III antiarrhythmics, antipsychotics, macrolide antibiotics, fluoroquinolone antibiotics, certain antihistamines) - increased risk of QT prolongation.
- Anticoagulants (e.g., warfarin) and antiplatelet agents (e.g., aspirin, NSAIDs) - increased risk of bleeding.
- Alcohol - may potentiate CNS depressant effects.
Moderate Interactions
- CYP2C19 inhibitors (e.g., omeprazole, cimetidine, fluoxetine, fluvoxamine) - may increase escitalopram plasma concentrations.
- CYP3A4 inhibitors (e.g., ketoconazole, ritonavir) - may increase escitalopram plasma concentrations.
- Drugs metabolized by CYP2D6 (e.g., metoprolol, desipramine, risperidone, flecainide, propafenone) - escitalopram is a weak inhibitor of CYP2D6, potentially increasing concentrations of these drugs.
- Diuretics - increased risk of hyponatremia.
Minor Interactions
- Not specifically categorized as minor, but general caution with other CNS depressants.
Monitoring
Baseline Monitoring
Rationale: To establish baseline and monitor treatment response.
Timing: Prior to initiation

Special Patient Groups
Pregnancy
Use during pregnancy should be considered only if the potential benefit justifies the potential risk to the fetus. There are risks associated with exposure to SSRIs during pregnancy, including neonatal withdrawal syndrome and persistent pulmonary hypertension of the newborn (PPHN).
Trimester-Specific Risks:
Lactation
Escitalopram is excreted into human breast milk. The decision to breastfeed should consider the developmental and health benefits of breastfeeding, the motherβs clinical need for escitalopram, and any potential adverse effects on the breastfed infant from escitalopram or from the underlying maternal condition. Monitor infants for sedation, poor feeding, and poor weight gain.
Pediatric Use
Approved for Major Depressive Disorder (MDD) in adolescents aged 12-17 years. Not approved for use in pediatric patients less than 12 years of age. Black Box Warning regarding increased risk of suicidal thoughts and behavior in children, adolescents, and young adults.
Geriatric Use
Elderly patients (β₯65 years) may be more sensitive to the effects of escitalopram and may have reduced clearance. A lower initial dose (e.g., 10 mg/day maximum) is recommended. Increased risk of hyponatremia and falls in this population.
Clinical Information
Clinical Pearls
- Escitalopram is the S-enantiomer of citalopram and is considered more potent and selective for serotonin reuptake inhibition.
- Patients should be advised that it may take several weeks to experience the full therapeutic effects.
- Abrupt discontinuation can lead to withdrawal symptoms (e.g., dizziness, nausea, headache, paresthesias, anxiety, agitation, sleep disturbances); gradual tapering is recommended.
- Sexual dysfunction (e.g., decreased libido, delayed ejaculation, anorgasmia) is a common side effect of SSRIs, including escitalopram, and can be a reason for non-adherence.
- Monitor for signs of serotonin syndrome, especially when co-administered with other serotonergic agents.
- Consider genetic testing for CYP2C19 poor metabolizers, as they may have higher escitalopram levels and require lower doses, though routine testing is not universally recommended.
Alternative Therapies
- Other Selective Serotonin Reuptake Inhibitors (SSRIs): Sertraline, Fluoxetine, Paroxetine, Citalopram, Fluvoxamine
- Serotonin-Norepinephrine Reuptake Inhibitors (SNRIs): Venlafaxine, Duloxetine, Desvenlafaxine
- Atypical Antidepressants: Bupropion, Mirtazapine, Trazodone, Vilazodone, Vortioxetine
- Tricyclic Antidepressants (TCAs): Amitriptyline, Nortriptyline, Imipramine
- Monoamine Oxidase Inhibitors (MAOIs): Phenelzine, Tranylcypromine (reserved for refractory cases)
- Psychotherapy (e.g., Cognitive Behavioral Therapy, Interpersonal Therapy)
- Electroconvulsive Therapy (ECT) for severe or refractory depression
