Introduction
Lexapro is the brand name for escitalopram, a prescription medication belonging to a group of antidepressants called selective serotonin reuptake inhibitors, or SSRIs. It is primarily used to treat depression and generalized anxiety disorder.
Lexapro works by increasing the availability of serotonin, a chemical messenger involved in mood, emotions, and other functions in the nervous system. Like other antidepressants, it usually takes time to produce its full therapeutic effect.
Understanding how Lexapro works, how it is taken, possible side effects, interactions, and precautions can help patients use it more safely.
What Is Lexapro?
Lexapro contains the active ingredient escitalopram.
It is an SSRI that works primarily by reducing the reuptake of serotonin in the brain. This allows more serotonin to remain available between nerve cells.
Lexapro is available as tablets and, in some markets, as an oral liquid.
It is a prescription medication and should be used under the supervision of a qualified healthcare professional.
What Is Lexapro Used For?
Lexapro is primarily prescribed for:
- Major depressive disorder
- Generalized anxiety disorder
Doctors may sometimes prescribe escitalopram for other conditions based on clinical judgment, although approved uses can vary by country.
The medication is generally most effective when used consistently and monitored appropriately.
How Does Lexapro Work?
Lexapro selectively inhibits the reuptake of serotonin in the brain.
Serotonin is involved in mood regulation, emotional processing, sleep, and several other biological functions.
By increasing serotonin activity between nerve cells, escitalopram may gradually improve symptoms of depression and anxiety.
The medication does not usually produce an immediate mood improvement. Benefits often develop gradually over several weeks.
Lexapro for Depression
Depression can involve persistent sadness, loss of interest, changes in sleep or appetite, low energy, difficulty concentrating, and feelings of hopelessness.
Lexapro may help reduce depressive symptoms when prescribed appropriately.
Treatment response varies from person to person. Some people begin noticing changes within the first few weeks, while the full benefit may take longer.
Lexapro for Anxiety
Lexapro is also used for generalized anxiety disorder.
People with generalized anxiety may experience excessive and persistent worry, restlessness, irritability, muscle tension, and difficulty controlling anxious thoughts.
With regular treatment, escitalopram may gradually reduce the frequency and intensity of anxiety symptoms.
Lexapro Dosage
The appropriate Lexapro dose depends on factors such as the condition being treated, age, response to treatment, and other medications.
A commonly used adult starting dose is 10 mg once daily, although some patients may be started at a lower dose.
Depending on response and tolerability, a healthcare professional may adjust the dose.
The maximum recommended dose for many adults is 20 mg per day, but the appropriate dose should always be determined by the prescriber.
Do not increase or decrease the dose yourself.
How to Take Lexapro
Lexapro is generally taken once daily.
It can usually be taken:
- With food
- Without food
- In the morning
- In the evening
Try to take it at approximately the same time each day.
If it causes sleepiness, your doctor may recommend taking it at night. If it makes you feel more alert, morning dosing may be more appropriate.
What Happens If You Miss a Dose?
If you forget a dose, take it when you remember unless it is nearly time for your next dose.
Do not take two doses together to make up for a missed dose.
If you frequently forget doses, using a daily reminder or taking the medication at the same time as another regular routine may help.
How Long Does Lexapro Take to Work?
Lexapro does not usually work immediately.
Some people may notice early changes in sleep, anxiety, or appetite before their mood improves. Meaningful improvement in depression or anxiety can take several weeks.
If symptoms do not improve or become worse after starting treatment, contact your healthcare professional.
Common Side Effects of Lexapro
Some people experience side effects, especially during the early stages of treatment.
Common side effects may include:
- Nausea
- Headache
- Dry mouth
- Sweating
- Fatigue
- Sleepiness
- Difficulty sleeping
- Increased anxiety at the beginning of treatment
- Sexual side effects
Lexapro and Nausea
Nausea is one of the more common early side effects of escitalopram.
Taking the medicine with food may help some people, although it does not eliminate nausea for everyone.
If nausea is severe, persistent, or accompanied by vomiting or dehydration, contact your healthcare professional.
Lexapro and Sleep
Escitalopram can affect sleep differently from person to person.
Some people experience sleepiness, while others have difficulty sleeping or feel restless.
If Lexapro consistently interferes with sleep, discuss the timing of the dose with your prescriber rather than changing it independently.
Lexapro and Sexual Side Effects
SSRIs can sometimes cause sexual side effects.
Possible problems include:
- Reduced sexual desire
- Delayed orgasm
- Difficulty reaching orgasm
- Erectile difficulties
- Reduced sexual satisfaction
Do not stop Lexapro suddenly because of sexual side effects.
Lexapro and Weight Changes
Weight changes can occur during antidepressant treatment, although the response differs among individuals.
Some people experience little change, while others may gain or lose weight.
Changes in appetite, activity, mood, and other medications can also influence body weight.
If substantial or unexplained weight changes occur, discuss them with your healthcare professional.
Lexapro and Alcohol
Alcohol can worsen some side effects of Lexapro, including drowsiness, dizziness, and impaired judgment.
Alcohol may also interfere with the management of depression or anxiety.
For these reasons, discuss alcohol use with your healthcare professional while taking escitalopram.
Lexapro Drug Interactions
Lexapro can interact with certain medicines and supplements.
Important interactions may involve:
- MAO inhibitors
- Other serotonergic medicines
- Certain antidepressants
- Some migraine medications
- Blood-thinning or antiplatelet medicines
- Certain drugs that affect heart rhythm
- Some herbal products, including St. John’s wort
Always provide your doctor and pharmacist with a complete list of prescription medicines, over-the-counter products, and supplements you use.
Lexapro and Serotonin Syndrome
Taking Lexapro with certain other medicines can rarely cause serotonin syndrome, a potentially serious condition caused by excessive serotonin activity.
Possible symptoms include:
- Agitation
- Confusion
- Sweating
- Fever
- Shivering
- Muscle stiffness
- Tremor
- Fast heartbeat
- Diarrhea
Severe symptoms require urgent medical attention.
Lexapro and Suicidal Thoughts
Antidepressants carry an important warning regarding increased suicidal thoughts and behavior in some children, adolescents, and young adults, particularly during the early stages of treatment or after dose changes.
This does not mean that everyone taking Lexapro will experience these effects.
Any new or worsening suicidal thoughts, severe agitation, unusual behavioral changes, or concerning mood changes should be reported immediately to a healthcare professional.
Emergency help should be sought when there is an immediate danger of self-harm.
Stopping Lexapro
Lexapro should generally not be stopped suddenly after regular use.
Abrupt discontinuation can cause withdrawal or discontinuation symptoms such as:
- Dizziness
- Irritability
- Anxiety
- Headache
- Sleep disturbances
- Nausea
- Tingling or unusual sensory sensations
A healthcare professional can create a gradual dose-reduction plan when discontinuation is appropriate.
Lexapro During Pregnancy
Depression and anxiety also require appropriate treatment during pregnancy, so decisions should balance the potential benefits and risks.
If you are pregnant, planning pregnancy, or become pregnant while taking Lexapro, discuss the medication with your healthcare professional.
Do not stop treatment suddenly without medical guidance.
Lexapro and Breastfeeding
Escitalopram can pass into breast milk in small amounts.
Discuss the risks and benefits with a healthcare professional rather than discontinuing treatment independently.
Lexapro in Older Adults
Older adults may be more sensitive to certain medication effects.
Healthcare professionals may consider age, other medications, kidney or liver function, and overall health when determining an appropriate dose.
Lexapro for Teenagers and Young Adults
Escitalopram is used in certain younger patients under appropriate medical supervision.
Parents, caregivers, and patients should report significant behavioral or mood changes promptly.
Lexapro vs Zoloft
Both are both SSRIs.
Lexapro contains escitalopram, while Zoloft contains sertraline.
One medication is not automatically better for everyone. The choice depends on the person’s symptoms, medical history, other medications, previous treatment response, and side-effect profile.
Lexapro vs Prozac
Both are also SSRIs.
Lexapro contains escitalopram, while Prozac contains fluoxetine.
They differ in how long they remain in the body, approved uses, dosing schedules, interactions, and individual tolerability.
A healthcare professional can determine which treatment is appropriate for a particular patient.

- Severe allergic reaction
- Fainting
- Seizure
- Severe confusion
- High fever with muscle rigidity
- Severe agitation
- Signs of serotonin syndrome
- Thoughts of suicide or immediate danger of self-harm
Conclusion
Lexapro, or escitalopram, is an SSRI medication commonly prescribed for depression and generalized anxiety disorder. It works by increasing serotonin activity in the nervous system and generally requires consistent use over several weeks to achieve its full therapeutic effect.
