Key Takeaways
- Lexapro (escitalopram) is an SSRI used to treat depression, anxiety, and other mental health conditions by increasing serotonin levels in the brain.
- While effective for many, Lexapro may cause side effects such as nausea, drowsiness, or weight changes, and should be tapered off under a health care provider's supervision.
- Medication decisions are most effective through shared decision-making, with a licensed psychiatric provider helping determine if Lexapro or another option best suits your needs.
Lexapro (escitalopram) is an FDA-approved prescription antidepressant used to treat depression and specific anxiety disorders in adults. It belongs to a group of medications called selective serotonin reuptake inhibitors, or SSRIs, which are commonly used to support mood and emotional balance.
Lexapro works by influencing brain chemistry to regulate mood. It’s important to understand the recommended dosages, safety precautions, and common side effects, along with situations where additional caution may be needed during treatment.
What is Lexapro?
Lexapro is an oral medication known to help improve mood and reduce symptoms associated with depression or anxiety.
How does Lexapro work?
Lexapro works by blocking the reabsorption of serotonin in the brain. This increases serotonin levels available for use by other neurons, so it can regulate emotions and benefit people with depression or anxiety disorders.
How does Lexapro make you feel?
How Lexapro makes one feel varies from person to person. Some people notice gradual improvements in mood, reduced anxiety, or an easier time managing daily stress. Others may experience changes in energy levels or focus as their bodies adjust to the medication.
Like most prescription medications, Lexapro can cause side effects. Common ones may include nausea, headache, sleep changes, dry mouth, constipation, changes in appetite or weight, and sexual dysfunction. Not everyone experiences side effects, and many improve as treatment continues, but it’s important to discuss any new or concerning symptoms with your provider.
Which Conditions Does Lexapro Treat
Lexapro has been approved for use in treating major depressive disorder (MDD) and generalized anxiety disorder (GAD) with a positive overall response rate. Additionally, the drug has been found effective in treating multiple other conditions off-label (meaning it’s often prescribed for uses other than what it was initially intended for).
“Lexapro is indicated for major depressive disorder and generalized anxiety disorder. It’s also used off-label for panic disorder, symptoms of depression in bipolar disorder, and certain premenstrual symptoms.”
– Talkspace psychiatrist Dr. Muhammad Munir
Lexapro for anxiety
Lexapro can be a successful treatment option for anxiety in many people. The Diagnostic and Statistical Manual of Mental Disorders (DSM-V) states that GAD manifests as excessive worry and other symptoms that last for more than six months.
At least three or more of the following symptoms are required for a GAD diagnosis to be made:
- Restlessness or feeling “keyed up” or on edge
- Being easily fatigued
- Difficulty concentrating
- Mind going blank
- Irritability
- Muscle tension
- Sleep disturbances
Lexapro treatment can effectively improve symptoms of GAD, panic disorder, OCD, and social anxiety. Furthermore, controlled studies focusing on relapse prevention show long-term efficacy.
Lexapro for depression
Adults and adolescents (ages 12 to 17) can use Lexapro as a treatment for major depressive disorder. A major depressive episode is characterized by a prominent and persistent depressed mood lasting nearly every day for at least two weeks.
At least five of the following nine symptoms must be present for MDD to be diagnosed:
- Depressed mood
- Change in appetite
- Loss of interest in usual activities
- Significant change in weight
- Increased fatigue
- Insomnia or hypersomnia
- Slowed thinking or impaired concentration
- Psychomotor agitation
- Feelings of guilt or worthlessness
- Suicide attempt or suicidal ideation
Off-label uses
Lexapro is used off-label to reduce symptoms associated with other mental health challenges beyond anxiety and depression. For example, it might be beneficial in treating:
- Obsessive-compulsive disorder (OCD)
- Panic disorder
- Post-traumatic stress disorder (PTSD)
- Premenstrual dysphoric disorder (PMDD)
- Social phobia
According to the official journal of the North American Menopause Society (NAMS), Lexapro can improve sleep quality and duration, potentially due to increased melatonin levels.
How Should You Take Lexapro?
The most common form of Lexapro is an oral tablet taken once daily, with or without food.
- For anxiety: The recommended starting escitalopram dosage for adults is 10 mg daily. Some people may require higher doses of up to 20 mg per day. Dosage should only be increased after at least a 1-week trial of the minimum dose. Long-term use of Lexapro for GAD should be monitored by a health care professional.
- For depression in adolescents: It’s recommended that adolescents start on a 10 mg dose of Lexapro daily for depression. After a minimum of 3 weeks, the dose may be increased to up to 20 mg.
- For depression in adults: Adults should take 10 mg of Lexapro each day for at least 1 week before potentially increasing to no more than 20 mg per day. For adults where Lexapro has been effective in treating depression, there can be long-term benefits to continuing the drug, but dosage and treatment should be reevaluated periodically by a medical professional.
Below is a table summarizing the typical starting doses, target ranges, and important dosage adjustments for different conditions treated with Lexapro.
How to take Lexapro
Take Lexapro exactly as prescribed by your health care professional. Swallow the tablet whole with water — do not crush, chew, or break it apart before swallowing it.
If you miss a dose, take it as soon as possible unless it’s almost time for your next scheduled dose — then skip the missed one and continue taking Lexapro according to schedule. Do not double up doses if you forget to take Lexapro.
Suddenly stopping your prescribed dosage can cause Lexapro withdrawal symptoms (such as dizziness, irritability, or flu-like sensations). Therefore, it’s important to taper off under your health care professional's guidance rather than discontinuing the medication on your own.

Get startedWhat are the Pros and Cons of Lexapro?
Lexapro offers several benefits in treating depression and anxiety, but it also comes with potential side effects and risks.
Below is a table that outlines the key pros and cons of Lexapro to help you evaluate its suitability for your treatment needs.
“Lexapro is an SSRI and increases the serotonin levels in the brain that relieve the symptoms of depression and anxiety features. It is a slow build-up medication that takes about 4 to 6 weeks for it to work. The dose flexibility and lack of interaction with other medications makes Lexapro an easier medication to use, especially when combination treatment is required.”
– Talkspace psychiatrist, Dr. Muhammad Munir
What Side Effects and Warnings Should You Watch for?
Common side effects of Lexapro include nausea, dry mouth, drowsiness, insomnia, increased sweating, and sexual dysfunction. These symptoms are usually mild and often go away after a few weeks of taking the medication.
Less common but more severe side effects include:
- Changes in appetite resulting in weight gain/loss
- Agitation or restlessness
- Difficulty concentrating
- Thoughts of suicide or self-harm
- Unusual behavior changes
- Tremors or shaking
- Confusion
- Fever or chills
- Fast heartbeat and seizures
If you experience these symptoms while taking Lexapro, contact your healthcare provider immediately for further evaluation and to discuss treatment options.
What Interactions or Precautions Come with Lexapro?
If you’re considering taking Lexapro, you must be aware of potential interactions with other medications and any warnings associated with the drug.
Interactions
Certain drugs can interact with Lexapro, increasing or decreasing its effectiveness. For example, if you take a monoamine oxidase inhibitor (MAOI) like phenelzine or tranylcypromine, do not take Lexapro without consulting your healthcare professional first and getting accurate medical advice.
Additionally, combining Lexapro with other drugs that affect serotonin levels in the body may lead to serious side effects, including an increased risk of serotonin syndrome.
Warnings
Make sure to tell your doctor if you’ve been on an MAO inhibitor within 14 days of starting or stopping Lexapro. Do not use Lexapro if you’re allergic to escitalopram or if you already take Pimozide.
Tell your doctor if you take any of the following:
- Linezolid
- Isocarboxazid
- Rasagiline
- Tranylcypromine
- Selegiline
- Phenelzine
- Stimulants
- Opioids
- Herbal products
- Migraine medication
- Medication for Parkinson’s disease
There are safety considerations regarding Lexapro and pregnancy, so be sure to let your doctor know if you’re pregnant or nursing. Talk to your doctor if you have also ever had:
- Seizures
- Liver/kidney disease
- Heart disease
- High blood pressure
- Low sodium
- Bleeding
- Bipolar disorder
- Addiction
- Thoughts of suicide
Is Lexapro Safe During Pregnancy or Breastfeeding?
The safety of Lexapro during pregnancy or breastfeeding depends on individual circumstances, including symptom severity and overall health.
It is essential to consult with a healthcare provider to carefully weigh the potential risks and benefits of using Lexapro during pregnancy or breastfeeding, ensuring the best possible outcome for both parent and baby.
Pregnancy considerations
When SSRIs are used during the third trimester, some newborns may experience what is often called neonatal adaptation symptoms. These can include temporary issues such as jitteriness, feeding difficulties, breathing changes, or irritability after birth. In most cases, these symptoms are mild and resolve on their own with monitoring and supportive care.
Individuals who take Lexapro during pregnancy may be encouraged to enroll in a pregnancy exposure registry, which helps researchers better understand medication safety during pregnancy. A healthcare provider can share information about available registries and whether participation may be helpful.
Breastfeeding considerations
Lexapro does pass into breast milk in small amounts. Many infants exposed through breastfeeding do not experience noticeable side effects, but healthcare providers may recommend monitoring for signs such as sleep changes, fussiness, or feeding concerns.
Decisions about breastfeeding while taking Lexapro often balance the benefits of treatment and breastfeeding with potential risks.
Making an informed decision
There is no one-size-fits-all answer when it comes to Lexapro use during pregnancy or breastfeeding. Shared decision-making with a healthcare provider or a psychiatrist is essential. Together, you can weigh the potential benefits of treatment against possible risks and decide on the safest approach for both parent and baby.
What are the Alternatives of Lexapro?
If Lexapro does not feel like the right fit, or if side effects are difficult to manage, there are other treatment options a psychiatric provider may consider. The right alternative can vary based on symptoms, medical history, and how someone responds to medication.
Zoloft
One alternative to Lexapro for anxiety and depression is Zoloft (Sertraline), another SSRI medication. Like Lexapro, Zoloft increases serotonin levels in the brain. Some people find that Zoloft has fewer side effects than Lexapro or that they have better results when taking it instead of Lexapro.
Wellbutrin
Another option for treating depression is Wellbutrin (Bupropion). This drug does not belong to the same class as SSRIs and does not treat anxiety. It works by boosting dopamine and norepinephrine in the brain.
As a result, Wellbutrin may relieve depressive symptoms without causing sexual dysfunction or weight gain like some antidepressants do. Additionally, Wellbutrin can benefit people who experience fatigue or lack motivation due to their condition.
Cymbalta
A third option for those looking for an alternative to Lexapro is Cymbalta (Duloxetine). This medication belongs to a different class than both SSRIs and Wellbutrin. It’s known as a serotonin-norepinephrine reuptake inhibitor (SNRI).
When comparing Cymbalta to Lexapro, Cymbalta has the added benefit of helping to relieve pain associated with conditions like nerve pain and fibromyalgia, in addition to treating depression and anxiety.
Effexor XR
Effexor XR (Venlafaxine) is yet another SNRI that may be prescribed instead of Lexapro to treat depression. It works similarly by increasing levels of norepinephrine and serotonin in the brain.
Effexor may have more side effects than other medications; therefore, health care professionals usually start individuals on lower doses before gradually increasing them over time if necessary.

Alcohol can amplify side effects such as drowsiness and dizziness when taking Lexapro. Many healthcare providers advise limiting or avoiding alcohol and consulting with a psychiatrist to ensure safety.
Why is Lexapro called the “Happy Pill”?
Lexapro is sometimes nicknamed the “Happy Pill” because it boosts serotonin levels in the brain, which can improve mood and reduce anxiety. While not a cure-all, many patients experience noticeable relief from depressive and anxious symptoms.
Does Lexapro make you forgetful?
Some people may notice mild memory problems or difficulty concentrating while taking Lexapro. These cognitive side effects are uncommon and often diminish over time or with dose adjustments under a healthcare professional's supervision.
