Escitalopram vs FluoxetineDETAILED OVERVIEW
What is Escitalopram?
Escitalopram is the active S-enantiomer of citalopram (R-enantiomer is pharmacologically inactive and may slightly interfere). Developed by Lundbeck (Lexapro FDA 2002), one of the cleanest SERT-selective SSRIs. Per Cipriani 2018 Lancet (PMID 29477251) network meta-analysis, top-3 of 21 antidepressants for efficacy-tolerability ratio (alongside vortioxetine, mirtazapine). Lader 2004 (PMID 15125014) trial showed MDD superiority over citalopram at 8 weeks. Generally better tolerability than citalopram, with lower QTc-prolongation risk (FDA 2011 warning for citalopram > 40 mg/day, escitalopram > 20 mg/day).
ATC code
N06AB10
Prescription
Prescription only (Rx)
Mechanism
Selective serotonin reuptake inhibitor (SSRI), SERT target
Half-life
27-32 h (once-daily dosing)
Onset
2-6 weeks (full antidepressant response)
Community accounts note Escitalopram as having one of the cleanest tolerability and side-effect profiles among SSRIs, supported by the Cipriani 2018 meta-analysis ranking it in the top tier for efficacy. Users describe a quiet subjective profile – lowering anxiety and supporting mood without strong stimulant or sedating character. Full therapeutic benefit typically emerges over 4-8 weeks, so patience is essential during initiation. Sexual dysfunction (delayed orgasm, reduced libido) is commonly reported, consistent with the SSRI class. The 27-32-hour half-life provides stable plasma levels with once-daily dosing. Caution: discontinuation syndrome on abrupt cessation – taper under clinical guidance. QT-prolongation risk at higher doses warrants ECG monitoring.

Side effects · 8
- Increased risk of suicidal thoughts and behavior in patients under 25, especially at treatment start and dose changes (FDA boxed warning); close monitoring required.
- Serotonin syndrome (agitation, hyperthermia, myoclonus, tachycardia, diarrhea), especially combined with other serotonergic drugs; can be life-threatening.
- Discontinuation syndrome on abrupt stopping: dizziness, headache, irritability, 'electric shock' sensations, sleep disturbance; requires slow tapering.
- Sexual dysfunction (reduced libido, delayed orgasm, erectile dysfunction) common (about 10–20%) and may persist.
- Gastrointestinal effects: nausea (10–15%), diarrhea, dry mouth, decreased appetite; usually in the first weeks.
- Dose-dependent QT prolongation (> 20 mg/day not recommended) with risk of torsades de pointes; insomnia, headache, sweating also common.
- Hyponatremia / SIADH, especially in the elderly and with diuretics; fatigue, confusion, seizures may be warning signs.
- Increased bleeding risk (with NSAIDs, aspirin, anticoagulants) and induction of mania/hypomania in those with bipolar predisposition.
Contraindications · 3
