What is Lexapro?

Lexapro (escitalopram) is an antidepressant from the group of drugs called selective serotonin reuptake inhibitors (SSRIs) and is used to treat certain types of depression and anxiety. It is not known how Lexapro worksbut it is thought to block the reuptake of serotonin by nerves. This results in an increase in serotonin concentrations in the nerve synapse (the space between two nerves).

Lexapro was FDA-approved on August 142002.
