EscitalopramBenefits, Dosage & Interactions
Also known as: Lexapro
Escitalopram, sold as Lexapro, is a selective serotonin reuptake inhibitor approved for major depressive disorder and generalized anxiety disorder, and used off-label for panic, social anxiety and OCD. It is the active half of the older drug citalopram, which is why effective amounts are roughly half.
How much Escitalopram do people take?
Not stated here. The cited trials each used their own protocol amounts, and Escitalopram is dosed by a prescriber or the approved product label — DoseRoutine records what you were told to take, it does not suggest an amount. Route reported: Oral (the route studied in the cited trials). Frequency reported: Set by the prescription or approved label, not by this record. These are amounts documented in the cited studies and labels for Escitalopram — they are reported for reference, not a recommendation. Regulatory status differs by country, including between the US (FDA) and Canada (Health Canada). Confirm any amount with a licensed clinician before you take it.

Quick answer
Escitalopram, sold as Lexapro, is a selective serotonin reuptake inhibitor approved for major depressive disorder and generalized anxiety disorder, and used off-label for panic, social anxiety and OCD. It is the active half of the older drug citalopram, which is why effective amounts are roughly half. Improvement usually appears over four to six weeks rather than immediately.
