What is Lexapro?
Lexapro is the brand name of the generic drug escitalopram, which is a type of antidepressant medication. It belongs to a group of antidepressants called selective serotonin reuptake inhibitors (SSRIs) first introduced in the late 1980s.
Scientists do not know exactly how Lexapro works. However, they do know that this drug has an effect on serotonin, a neurotransmitter in the brain involved in mood, sleep and other bodily functions. One theory is that Lexapro helps balance serotonin levels in the brain, which can reduce anxiety and improve mood.
SSRIs are generally effective and have fewer side effects than some of the older antidepressants, such as monoamine oxidase inhibitors (MAOIs). Lexapro, which comes in pill or liquid form, is used today to treat a variety of mental disorders.
In the United Kingdom, escitalopram is sold under the brand name Cipralex.
uses of lexapro
Escitalopram, the generic form of Lexapro, is primarily used to treat depression and generalized anxiety disorder (GAD). Initially, it was only used to treat depression, but research has shown it to be effective in treating mood disorders4 and anxiety disorders.
A doctor may prescribe Lexapro for other uses if he or she thinks it will help. A doctor may prescribe Lexapro for other uses if he or she thinks it will help. For example, he or she might prescribe Lexapro for conditions such as obsessive-compulsive disorder (OCD), post-traumatic stress disorder (PTSD), social anxiety disorder, and even migraines.
If Lexapro doesn’t work for you, your doctor will try to find another medication that may help, such as another SSRI or a class of antidepressants. Psychotherapy may also be helpful.
Before taking Lexapro
Lexapro is prescribed to treat anxiety disorders, depressive disorders, and other mood disorders, sometimes in combination with other medications. Therefore, a mental health diagnosis is usually needed before a doctor will prescribe Lexapro.
Your primary care physician can prescribe Lexapro. But a mental health professional can prescribe medications and manage other therapeutic needs, such as combining medications with psychotherapy.
Mental health professionals who can prescribe medications include psychiatrists, mental health nurses, and psychiatric pharmacists.
Before you start taking Lexapro to treat anxiety or depression, tell your doctor if you are allergic or hypersensitive to escitalopram, or if you are pregnant or breastfeeding. Also tell your doctor if you have a history of any of these medical conditions, which may be exacerbated by Lexapro:
Low salt level (hyponatremia)
Suicidal thoughts or behavior
Tell your doctor about all medications, supplements and vitamins you are currently taking. While some medications have minor interaction risks, others may be downright harmful or give rise to other considerations about whether the benefits of treatment outweigh the harm in your case.
Lexapro Precautions and Contraindications
Taking Lexapro comes with many precautions.7 You can reduce your risk by knowing who should not take this medication and understanding the black box warning.
Who should not take Lexapro
Lexapro is not safe for everyone. Some people should definitely not take Lexapro or take it with caution, including:
People allergic to escitalopram: You should not take Lexapro if you are hypersensitive to escitalopram oxalate. This means you have a known allergy to this medicine and have symptoms of an allergic reaction when you take it, such as difficulty breathing or swelling of the face, mouth or tongue.
Children: The safety and effectiveness of Lexapro in children under 12 years of age have not been well established. Some smaller studies have found this drug to be beneficial for young children with anxiety disorders with minimal side effects, but more research is needed to be sure.
Pregnant or nursing: Use Lexapro with caution if you are pregnant or breastfeeding, as the drug may be passed on to your baby. The FDA also reports that SSRIs taken after the 20th week of pregnancy increase the risk of persistent pulmonary hypertension in children sixfold.9 Your doctor should discuss this with you; if not, be sure to ask about the potential risks.
Elderly: The side effects of this drug may be more severe in the elderly, for example, causing blood sodium levels to drop to dangerous levels.10 Your doctor should monitor your dose and adjust it as needed to reduce the severity of its effects.

While rare, there have been reports of people developing a life-threatening reaction after combining escitalopram with linezolid, a drug used to treat infections such as pneumonia.

How long does it take to withdraw from Lexapro?
When is the best time to take Lexapro for anxiety?
The answer to this question depends, in part, on the side effects that occur. If the medication makes you drowsy, for example, it’s best to take it at night. On the other hand, if it makes you more alert, taking it in the morning may prevent you from having trouble sleeping. Check with your doctor to determine the best time of day to take Lexapro for you.
How does Lexapro feel in the first week?
You probably won’t notice any real improvement in your depression or anxiety during the first week of using Lexapro. However, some side effects may occur, such as headache, nausea, diarrhea, dry mouth, nervousness, restlessness, fatigue, insomnia, and increased blood pressure.
These side effects should go away in one to two weeks. Otherwise, talk to your doctor to determine if this medication is right for you or if the dose needs to be adjusted.
How long does it take for Lexapro to work?
While you may notice some improvements in the first few weeks, such as better sleep, more energy, or increased appetite, it may take up to eight weeks to feel the full benefits of this medication. Therefore, you may not notice significant improvements in your feelings of depression or anxiety for a few months.
What should you expect when you increase your dose of Lexapro?
If your doctor increases your dose of Lexapro, you may notice side effects similar to those seen when you initially took this medication for a day or two. Your doctor may also want to follow you closely to make sure that your condition does not worsen or that you do not experience any significant negative side effects.
How do you know if Lexapro is effective?
Lexapro is unlikely to create a monumental change overnight. So you can tell if it’s working by looking at how you’ve been feeling over the past few days. If you seem to feel less depressed or anxious than before, Lexapro is working. Mark on your calendar that you’ll see each other once a week and compare how you feel. If you don’t notice any change over time or if your condition begins to worsen, contact your doctor immediately to discuss the necessary changes.
Why does Lexapro cause weight gain?
There are several reasons why Lexapro may cause you to gain weight. One is that it affects serotonin levels, which affects appetite. Research also indicates that some people are more likely to gain weight when taking this drug, including those with a lower BMI at the start of Lexapro treatment, people with a low level of education, and people with a family history of obesity.
What happens if you overdose on Lexapro?
One of the most notable effects of a Lexapro overdose is the development of a heart rhythm problem where there are prolonged intervals between contraction and relaxation.
In such cases, a single dose of activated charcoal may be recommended. If you or someone you know has taken an overdose of Lexapro, seek immediate medical help or call emergency health services.
