Escitalopram

Escitalopram oxalate · Lexapro

An SSRI for major depressive disorder and generalized anxiety disorder. This reference follows the Lexapro label, separating indication-specific pediatric dosing and practical serotonin, withdrawal and cardiac precautions.

Therapeutic class
Selective serotonin reuptake inhibitor
Common brand
Lexapro
Reference focus
U.S. Lexapro oral tablet label
Essential safety

Monitor mood and check serotonergic combinations.

The antidepressant boxed warning concerns suicidal thoughts and behaviors in children, adolescents and young adults. Review MAOIs and other interacting drugs before treatment; possible serotonin syndrome requires urgent assessment.

Warnings and precautions
01

Indications

Approval depends on both diagnosis and age.

Approved uses

Lexapro is indicated for MDD in adults and patients aged 12 years or older, and GAD in adults and patients aged 7 years or older. It is an oral prescription medicine; these age limits do not establish effectiveness below the respective thresholds.

Reference boundaries

This profile follows the branded Lexapro label. Some generic labels may retain different pediatric indication wording. Other psychiatric uses require an indication-specific assessment and are not represented here as FDA-approved uses.

02

Dosage and administration

Once-daily dosing with different minimum titration intervals.

Starting dose and titration

All listed populations start at 10 mg once daily; 20 mg once daily is the labeled maximum. Increase only after assessing response and tolerability. The adult MDD fixed-dose trial did not establish extra benefit at 20 mg over 10 mg.

Indication / populationEarliest increase to 20 mg
Adult MDDAfter at least 1 week
MDD, age ≥12 yearsAfter at least 3 weeks
Adult GADAfter at least 1 week
GAD, age ≥7 yearsAfter at least 2 weeks

Administration and formulations

Take once daily, morning or evening, with or without food. Lexapro tablets contain 5, 10 or 20 mg; the 10 and 20 mg tablets are scored. The label describes a 1 mg/mL oral solution but explicitly states that this branded solution is not currently marketed.

Older adults, liver and kidney function

The recommended dose for most older patients and patients with hepatic impairment is 10 mg daily. Mild or moderate renal impairment needs no dose adjustment; dosing is undetermined at creatinine clearance below 20 mL/min, requiring caution and individualized review.

Stopping and MAOI transitions

Reduce gradually whenever possible and monitor withdrawal symptoms. Intolerable symptoms may require returning to the prior dose followed by a slower reduction. Keep at least 14 days between stopping a psychiatric MAOI and starting escitalopram, or stopping escitalopram and starting a psychiatric MAOI.

03

Safety

Mood, serotonin toxicity and withdrawal require active follow-up.

Warnings and precautions

Clinical alert

Screen for bipolar disorder before treatment; activation of mania or hypomania can occur. Use cautiously with a seizure history. Hyponatremia, often involving SIADH, is more likely with older age, diuretics or volume depletion; confusion, weakness or unsteadiness warrant assessment, and severe cases can cause seizures.

Serotonin syndrome can occur alone or with serotonergic combinations. Fever, agitation, tremor, hyperreflexia or diarrhea with clinical deterioration require urgent care; stop implicated drugs and provide supportive treatment when syndrome is diagnosed. Bleeding risk rises with drugs affecting hemostasis. Anatomically narrow untreated eye angles confer an angle-closure risk.

QT effects depend on dose. UK MHRA advice prohibits use with known or congenital QT prolongation or other QT-prolonging medicines; it recommends considering ECG review in cardiac disease, correcting potassium or magnesium deficits, and ECG assessment for palpitations or syncope. These are UK restrictions, distinct from the U.S. contraindication list.

Contraindications

Do not combine with psychiatric MAOIs or use within the 14-day washout in either direction. Do not initiate during linezolid or intravenous methylene blue treatment. Pimozide coadministration and hypersensitivity to escitalopram, citalopram or ingredients are contraindications.

Boxed warning · Suicidal thoughts and behaviors

Boxed warning

Antidepressant trials show increased suicidal thoughts and behaviors in pediatric and young adult patients. Monitor every treated patient for worsening mood or new suicidality, especially early in treatment and after dose changes; patients and caregivers should promptly report changes.

Adverse reactions

Common trial effects include nausea, insomnia, sweating, fatigue, somnolence and sexual dysfunction. Ask about baseline and emerging sexual concerns. Postmarketing reports include QT prolongation and torsades de pointes; spontaneous reports do not establish their frequency.

04

Drug interactions

Reconcile prescription drugs, OTC products and supplements.

Serotonergic and contraindicated combinations

Review other SSRIs/SNRIs, triptans, tramadol, fentanyl, lithium, buspirone, amphetamines, tryptophan and St. John’s wort for serotonin toxicity. MAOIs, linezolid/IV methylene blue and pimozide require the restrictions above. Do not duplicate escitalopram with citalopram.

Hemostasis, metabolism and cardiac risk

NSAIDs, aspirin, antiplatelet drugs and anticoagulants increase bleeding risk; monitor INR carefully when warfarin is used. Escitalopram can increase exposure to CYP2D6 substrates, exemplified by desipramine. Review QT-prolonging medicines and electrolyte-depleting drugs using the applicable local cardiac guidance.

05

Use in specific populations

Age and reproductive context alter monitoring.

Pregnancy

Available human data have not established an increased risk of major birth defects or miscarriage. Late exposure can involve neonatal poor adaptation or persistent pulmonary hypertension; use near delivery is associated with postpartum bleeding risk. Discuss untreated illness, relapse and neonatal planning; avoid unsupervised abrupt cessation.

Breastfeeding

Escitalopram and its metabolite enter milk. LactMed reports low exposure with maternal doses up to 20 mg/day and says a needed treatment is not itself a reason to stop breastfeeding. Monitor infant sedation, restlessness, feeding and weight gain, especially in young exclusively breastfed infants or with multiple psychotropics.

Children and older adults

Follow the diagnosis-specific age approval. Monitor height and weight in pediatric patients because appetite and weight changes can occur. Older patients have higher exposure and a greater risk of clinically important hyponatremia; the usual recommended dose is 10 mg daily.

Organ impairment

Use the hepatic and renal dosing distinctions above. Recently infarcted or unstable cardiac patients were not systematically evaluated in the clinical program; review cardiovascular status and interacting drugs rather than assuming trial safety generalizes to every cardiac condition.

06

Clinical pharmacology

Serotonin reuptake inhibition with a roughly one-day half-life.

Mechanism

Escitalopram is the S-enantiomer of citalopram. Its antidepressant activity is associated with potentiating central serotonergic signaling through inhibition of serotonin reuptake.

Disposition

Peak concentrations follow an oral dose at about 5 hours; food does not materially alter absorption. Protein binding is about 56%. CYP2C19 and CYP3A4 contribute to hepatic metabolism. Terminal half-life is approximately 27–32 hours and steady state is reached in about a week.

Half-life
About 27–32 hours
Steady state
About 1 week
07

Monitoring and counseling

Follow symptoms, tolerability and safety after initiation and dose changes.

Before and during therapy

Confirm diagnosis, bipolar/mania history, suicidality, interacting drugs and relevant cardiac or electrolyte risk. Follow mood, function, activation, adverse effects and sexual health. Check sodium when symptoms or risk factors warrant it; pediatric growth requires follow-up.

Counseling

Take consistently and follow a clinician-directed taper. Avoid driving until the individual response is known; concomitant alcohol use is not advised. Report new suicidality, severe agitation with fever, abnormal bleeding, eye pain or new visual symptoms, fainting, confusion or seizures promptly.

Overdose

Overdose can produce delayed seizures, QRS/QT changes and arrhythmias. Urgent poison-center or emergency assessment is needed; cardiac monitoring may need to continue after an apparently mild early presentation.
