Can you stop taking Lexapro cold turkey?
Direct Answer
Stopping Lexapro (escitalopram) abruptly is not recommended. While not medically dangerous like benzodiazepine withdrawal, sudden discontinuation commonly causes "SSRI discontinuation syndrome" — brain zaps (electric shock sensations), dizziness, nausea, irritability, insomnia, and flu-like symptoms. These typically start within 2-4 days of stopping and can last 1-3 weeks. A gradual taper over 2-4 weeks (reducing by 25-50% at intervals) significantly reduces or eliminates these symptoms. Always work with your prescriber on a tapering plan.
Based on published clinical trial data and FDA prescribing information. This is not medical advice — always consult your healthcare provider.
