The active ingredient in Lexapro is escitalopram. Lexapro belongs to a group of drugs called selective serotonin reuptake inhibitors (SSRIs). To learn more about Lexapro, see this in-depth article.

Generalized anxiety disorder (GAD), also called anxiety, is a condition that causes you to experience intense, excessive, uncontrollable worry. These worries are about common situations and occurrences, such as your health, family, or finances.

GAD is different from typical feelings of anxiety. Everyone experiences anxiety at some time. But in people with GAD, these feelings are excessive, overwhelming, and don’t go away. The feelings can be intense enough to interfere with your ability to carry out daily activities and maintain relationships.

What are the symptoms of anxiety?

GAD can have physical and mental symptoms.

Mental symptoms of anxiety include:

  • difficulty concentrating or relaxing
  • feeling irritable, nervous, or as if you’re overthinking
  • fatigue
  • difficulty sleeping
  • an inability to let go of worries

Physical symptoms of anxiety include:

  • tension in your muscles
  • trembling or twitching in your muscles
  • sweating
  • dry mouth
  • repeated gastrointestinal issues, such as diarrhea or stomach aches

People with GAD experience symptoms over long periods of time (at least 6 months) and have worries about many different topics. They’re often unable to identify a source of their worries.

Lexapro is prescribed to treat GAD in adults and children ages 7 years and older. Here are more details on how Lexapro works to treat anxiety.

How does Lexapro work?

Doctors are still trying to understand the exact cause of GAD. While there is some understanding, it’s not fully known what causes the condition or why it affects certain people but not others. It’s thought that people with GAD may have increased or changed activity in certain parts of the brain related to introspective thinking and managing worrying situations.

Lexapro increases the amount of serotonin in your central nervous system (CNS). Your CNS consists of your brain and spinal cord. Serotonin is a neurotransmitter (a certain type of chemical messenger) made naturally by your body. It’s thought that serotonin plays a key role in regulating your mood and emotions, including managing feelings of anxiety.

Serotonin can be absorbed from the brain back into your blood. Lexapro blocks the reabsorption of serotonin, which increases the level of serotonin in the brain.

Is Lexapro used in children?

Yes, Lexapro is used in children. For treating GAD, Lexapro is approved for use in children ages 7 years and older.

Studies have shown Lexapro to be effective at improving anxiety symptoms related to GAD in adults and children ages 7 years and older.

SSRIs, including Lexapro, are typically considered first-choice treatments for GAD. For example, guidelines for treating GAD from the American Association of Family Physicians recommend SSRIs such as Lexapro as first-line treatments.

Lexapro may be used alone to treat GAD. It may also be combined with psychotherapy (talk therapy), such as cognitive behavioral therapy.

Boxed warning: risk of suicidal thoughts and behaviors in children and young adults

This drug has a boxed warning. This is the most serious warning from the Food and Drug Administration (FDA). A boxed warning alerts doctors and patients about drug effects that may be dangerous.

Antidepressants, including Lexapro, can cause a short-term increase in the risk of suicidal thoughts and behaviors in children and young adults ages 24 years and younger. It’s not known whether this risk continues with long-term Lexapro treatment. It’s important to note that depression and other mental health conditions also increase this risk.

During treatment with Lexapro, your doctor will closely monitor your mental health. Immediately let them know if you develop symptoms of suicidal thoughts or behaviors. You can also call or text the 988 Suicide and Crisis Lifeline at 988. If you’re comfortable doing so, consider letting a close family member or friend know you’re taking Lexapro. They can help monitor for any changes in your mood and behavior.

What other warnings should I know about?

In addition to boxed warnings, Lexapro has other warnings. If any of the following medical conditions or other health factors apply to you, talk with your doctor before using Lexapro.

If you’re calling on behalf of someone else, stay with them until help arrives. You may remove weapons or substances that can cause harm if you can do so safely.

If you are not in the same household, stay on the phone with them until help arrives.
