What is Lexapro?

Lexapro (generic name: Escitalopram) is a prescription antidepressant that belongs to the class of drugs called SSRIs (Selective Serotonin Reuptake Inhibitors). It is commonly used to treat major depressive disorder (MDD) and generalized anxiety disorder (GAD).
Lexapro works by increasing the levels of serotonin, a natural chemical in the brain that helps improve mood, sleep, and energy levels.

Important Information

  • Lexapro is not habit-forming, but sudden discontinuation can cause withdrawal symptoms.

  • It may take 1–4 weeks before you feel the full benefit of this medication.

  • Do not take Lexapro with MAO inhibitors or within 14 days of stopping one, as it can cause dangerous interactions.

  • Children, adolescents, and young adults may have an increased risk of suicidal thoughts when taking antidepressants.
