What is Lexapro?

Lexapro is a selective serotonin reuptake inhibitor, or SSRI. It is the popular brand name of escitalopram oxalate.

What is Lexapro Used For?

Lexapro is indicated (recommended) for both short-term and long-term treatment of major depressive disorder (MDD) in those aged 12 and up as well as for short-term treatment of generalized anxiety disorder (GAD) in adults.

How Does Lexapro Work?

Lexapro is a selective serotonin reuptake inhibitor, which means that it works to inhibit the reuptake (reabsorption) of the neurotransmitter serotonin. By inhibiting serotonin reuptake, Lexapro and other SSRIs leave more serotonin in the brain available for binding with certain receptors. This binding may enhance and stabilize mood.

Lexapro stands apart from many other drugs in its class for affecting serotonin almost exclusively, having little effect on the neurotransmitters dopamine and norepinephrine (which are also associated with mood).

How Long Does it Take for Lexapro to Work?

The answer to this question will vary by individual. That being said, it usually takes anywhere from 4 to 6 weeks for patients to feel the full effect of this medication.
