Basics

Lexapro®, the brand name for generic escitalopram, is a commonly prescribed antidepressant that belongs to the class of selective serotonin reuptake inhibitors (SSRIs). It’s approved by the United States Food and Drug Administration to treat major depressive disorder and generalized anxiety disorder in adults and adolescents, and it’s also sometimes used off-label for conditions including social anxiety disorder, obsessive-compulsive disorder, panic disorder, post-traumatic stress disorder, premenstrual dysphoric disorder, and certain menopause-related symptoms, such as hot flashes and night sweats.

Lexapro works by increasing available levels of the chemical serotonin in the brain, which helps improve mood, reduce anxiety, and enhance emotional stability over time. 

Lexapro is taken once daily in tablet or liquid form and is known for its relatively mild side effects. In rare cases, more serious reactions can occur, such as serotonin syndrome or suicidal thoughts, particularly when starting treatment or adjusting the dose. Always take Lexapro as prescribed.

FAQs

No. Lexapro and Xanax may both be prescribed to treat anxiety, but they are two different kinds of medications that work differently in the body. Lexapro (escitalopram) is an SSRI, which gradually improves mood and lowers anxiety by increasing available serotonin levels in the brain. Xanax (alprazolam) is a benzodiazepine, which produces a sedative effect by acting on the neurotransmitter GABA in the brain. While it may take several weeks for Lexapro to improve symptoms, the effects of Xanax may be felt within about 30 minutes. The two drugs also carry different side effects and risks.

The “happy pill” is not a medical term, but Lexapro may be referred to as such because the drug is an antidepressant that increases available levels of the chemical serotonin in the brain, which is associated with improved mood and mental balance.

Lexapro is not generally considered to be either energizing or sedating, but each person may react differently to this medication. Some common side effects of Lexapro include sleepiness or tiredness, but these tend to resolve as your body adjusts to the medication.
