What is Lexapro (Escitalopram)?
Lexapro, the brand name for escitalopram, is a widely prescribed antidepressant medication belonging to the selective serotonin reuptake inhibitor (SSRI) class. It is FDA-approved for the treatment of Major Depressive Disorder (MDD) and Generalized Anxiety Disorder (GAD).
How Does Lexapro Work?
Increased Serotonin Levels: Lexapro blocks the reuptake of serotonin into neurons. By preventing this reuptake, more serotonin is available in the synaptic space to transmit messages between nerve cells, which helps improve mood and reduce anxiety.

Selective Action: Escitalopram, the active ingredient in Lexapro, selectively targets serotonin transporters, leading to more efficient serotonin reuptake inhibition compared to other SSRIs.
What is Lexapro Used For?
Lexapro is primarily prescribed for:
Major Depressive Disorder (MDD): Effective in reducing symptoms of depression, such as persistent sadness, loss of interest in activities, and fatigue.
Generalized Anxiety Disorder (GAD): Helps alleviate symptoms of anxiety, including excessive worry, restlessness, and difficulty concentrating.
How Effective is Lexapro?
Depression and Anxiety: Clinical studies consistently demonstrate Lexapro’s ability to significantly reduce symptoms of both depression and anxiety. It is often considered a first-line treatment because of its well-documented efficacy and tolerability.
Obsessive-Compulsive Disorder (OCD): Although not FDA-approved for OCD, Lexapro is often prescribed off-label due to its effectiveness in increasing serotonin levels, which can alleviate obsessive thoughts and compulsive behaviors.
Other Off-Label Uses: Lexapro is also used to treat conditions such as panic disorder, social anxiety disorder, post-traumatic stress disorder (PTSD), premenstrual dysphoric disorder (PMDD), binge eating disorder, and bulimia nervosa.
What Does Lexapro Feel Like When It First Starts Working?
When you start taking Lexapro (escitalopram), the experience can vary from person to person. Here are some common experiences and changes you might notice during the initial phase of treatment:
Initial Phase (First Few Days to Weeks)
Gradual Improvement: Lexapro typically takes 1 to 2 weeks to start showing noticeable improvements in mood and anxiety symptoms. However, some people may take longer to feel better.
Increased Energy: Some individuals may notice a slight increase in energy levels before significant changes in mood occur. This can help you feel more capable of handling daily activities.
Reduced Anxiety: There may be a decrease in the intensity and frequency of anxious thoughts and feelings, which can help you feel more at ease and less overwhelmed.
Side Effects: Initial side effects can include nausea, headache, dizziness, insomnia, or a feeling of being “jittery” or nervous. These often diminish as your body adjusts to the medication. It is important to remember that these side effects are usually temporary.
Common Initial Experiences
Nausea and Gastrointestinal Issues: Nausea, upset stomach, or diarrhea can occur, especially in the first few days. Taking Lexapro with food may help alleviate these symptoms. Staying hydrated and eating small, frequent meals can also be beneficial.
Changes in Sleep Patterns: Some people experience insomnia or trouble falling asleep, while others may feel more tired or sleepy than usual. Establishing a regular sleep routine can help manage these changes.
Dry Mouth: A common side effect that can be managed by staying hydrated and chewing gum or sucking on sugar-free candies.
Increased Sweating: Some individuals may notice increased sweating, especially during physical activity or at night. Wearing breathable clothing and using antiperspirants can help.
Intermediate Phase (Weeks 2 to 6)
Mood Improvement: Gradually, you may start to notice a lift in your mood. Feelings of sadness, hopelessness, and lack of interest in activities may begin to decrease.
Better Sleep: Improvements in sleep patterns, with a decrease in insomnia or more restful sleep, can significantly enhance your overall well-being.
Improved Concentration: Better focus and concentration as depressive symptoms improve can lead to increased productivity and a greater sense of accomplishment.
Full Effect (6 to 12 Weeks)
Stabilized Mood: The full therapeutic effect of Lexapro typically becomes more noticeable within 6 to 12 weeks. You may feel a more consistent improvement in your overall mood and outlook on life.
Daily Functioning: Increased ability to carry out daily activities and responsibilities with less emotional distress can lead to a higher quality of life.
Decreased Anxiety: Significant reduction in symptoms, leading to a calmer and more stable emotional state, can help you feel more in control and less anxious.
Individual Variations
Personal Response: Everyone’s response to Lexapro is unique. Some may experience noticeable improvements quickly, while others might see gradual changes. It is important to be patient and give the medication time to work.
Communication with Healthcare Provider: Regular check-ins with your healthcare provider are crucial. They can adjust the dosage or provide additional support to manage any side effects or concerns. Keeping a journal of any changes in behavior, mood, or side effects can be helpful for these discussions.
Important Considerations
Consistency: Take Lexapro at the same time each day to maintain consistent levels in your system. This helps maximize the medication’s effectiveness and minimize side effects.
Patience: It can take several weeks to experience the full benefits, so it’s important to be patient and continue taking the medication as prescribed. Do not stop taking Lexapro without consulting your healthcare provider, even if you feel better.
Side Effects Management: Discuss any side effects with your healthcare provider. They can offer strategies to manage them effectively and determine whether adjustments to your treatment plan are needed.
Dosing and Administration
The typical starting dose of Lexapro for adults is 5-10 mg once daily, which may be increased depending on the patient’s response and tolerability. It can be taken with or without food, preferably at the same time each day to maintain consistent blood levels.
What are the Side Fffects of Lexapro?
Like all medications, Lexapro can cause side effects. Common side effects include:
Headache: A frequent initial side effect that often diminishes over time.
Nausea: Taking Lexapro with food can help alleviate this symptom.
Fatigue: Some patients may feel tired or sluggish.
Dry Mouth: Staying hydrated and chewing gum can help manage dry mouth.
Insomnia: Taking Lexapro in the morning may reduce sleep disturbances.
Sexual Dysfunction: Problems with orgasm or ejaculatory delay may occur and often persist.
Rare/Serious Side Effects:
Low Sodium Blood Levels: Symptoms may include headache, weakness, and difficulty concentrating.
Teeth Grinding: Known as bruxism.
Angle Closure Glaucoma: Symptoms include eye pain, vision changes, and swelling around the eye.
Serotonin Syndrome: A rare but serious condition with symptoms like shivering, diarrhea, confusion, severe muscle tightness, and seizures.
Potential Contraindications
Lexapro should not be used in conjunction with monoamine oxidase inhibitors (MAOIs) or within 14 days of stopping an MAOI due to the risk of serotonin syndrome. It is also contraindicated in patients with known hypersensitivity to escitalopram or citalopram.
FDA Approval and Meta-Analysis Evidence
Lexapro was first approved by the FDA in 2002 for MDD and GAD. Meta-analyses have indicated that Lexapro may be slightly more effective than other antidepressants, with fewer side effects, making it a preferred choice for many healthcare providers.
How Lexapro Differs from Other SSRIs
Escitalopram’s unique mode of action involves binding to a secondary site on the serotonin transporter, which modulates the affinity of the primary binding site. This results in a more efficient blockade of serotonin reuptake, potentially leading to faster symptom relief and superior efficacy compared to other SSRIs.
Important Considerations Before Taking Lexapro
Discuss Symptoms: Inform your healthcare provider about the symptoms that bother you the most.
Suicidal Thoughts: Let your provider know if you have any thoughts of suicide or harming yourself.
Medication History: Share your past experiences with other medications.
Side Effects: Report any side effects to your provider. Some may improve over time, while others may require changes in medication.
Other Conditions: Mention any other psychiatric or medical problems, including a history of bipolar disorder.
Pregnancy and Breastfeeding: Discuss the risks and benefits of taking Lexapro if you are pregnant, planning to become pregnant, or breastfeeding.
Alcohol and Drugs: Avoid alcohol and illegal drugs while taking Lexapro, as they may decrease the benefits and increase adverse effects.
Conclusion
Lexapro (escitalopram) is a well-studied and effective treatment for major depressive disorder and generalized anxiety disorder. It offers advantages in terms of efficacy and tolerability compared to other SSRIs. As always, it is crucial to follow your healthcare provider’s guidance regarding its use, dosing, and monitoring.
