Lexapro is classified as a selective serotonin reuptake inhibitor (SSRI). Withdrawal symptoms have been reported with abrupt or rapid discontinuation. The most commonly reported withdrawal symptoms include fatigue, stomach pain or nausea, dizziness/light-headedness, tremor, chills, sweating, and incoordination. Other reported symptoms include dysphoric mood, impaired memory, insomnia, irritability, shock sensations, headache, and aggression.
Withdrawal symptoms usually begin 1—3 days after abrupt discontinuation but should stop after 1-2 weeks. Significant withdrawal symptoms are rare. Gradual tapering is recommended to decrease or prevent withdrawal symptoms. It is always advisable to consult your doctor before stopping any medication.
