  • Escitalopram, better known by the brand name Lexapro, is a prescription medication used to treat depression, anxiety, OCD, PTSD, and other mental health conditions.
  • Escitalopram is an SSRI, which works by increasing the availability of serotonin in the brain. 
  • Like all medications, escitalopram can have side effects, some of which may be severe. 
  • If you’re considering taking an antidepressant, talk to your doctor about Lexapro’s positive and negative effects.

Depression, anxiety, and other mental health conditions can have a tremendous impact on your ability to enjoy daily life. For some people, a combination of therapy, lifestyle changes, and medication can help restore balance. Escitalopram (also known as Lexapro) is one of the most popular antidepressants on the market today, helping millions of Americans enjoy life to the fullest. Learn about Lexapro and how you can manage your mental health.

What Is Escitalopram and What Is It Used For?

Escitalopram, commonly recognized by the brand name Lexapro, is an selective serotonin reuptake inhibitor (SSRI) that was approved by the FDA in 2002. This medication has been shown to be very effective, so it has quickly become a first-line medication for people managing depression and anxiety.

Besides its primary prescribed uses, escitalopram has several off-label uses for conditions like obsessive-compulsive disorder (OCD), post-traumatic stress disorder (PTSD), premenstrual dysphoric disorder (PMDD), panic disorder, and more. The term “off-label” means these uses are not officially approved by the FDA, and effectiveness for these conditions can vary.

How Does Escitalopram Work?

As an SSRI, escitalopram works by increasing the brain’s levels of serotonin and supporting mental health balance on a chemical level.

Serotonin is a neurotransmitter that plays a key role in mood regulation, emotion, and the stress response. After it sends signals to the brain, it is reabsorbed in a process called reuptake.

By preventing serotonin reuptake from happening too quickly, escitalopram helps keep a higher level of this chemical available in the brain. For people who have an imbalanced serotonin level due to depression or anxiety, SSRIs lead to improved mood and a less-intense response to stress.

Escitalopram Dosage and Administration

Escitalopram is typically available in tablet form in 5, 10, or 20 milligram dose strengths. The exact dosage of escitalopram can vary based on your condition, response to the medication, and other factors. Most doctors prefer to start this medication at a lower dose and adjust based on individual reactions.

Note that the dosage regimen above is a general guideline; only a healthcare provider can determine the appropriate dosage for an individual.

How Should I Take Escitalopram?

If escitalopram is part of your treatment plan, be sure to take your medication exactly as your doctor prescribes. You can take this drug with or without food. However you choose to take escitalopram, be sure to take it at the same time(s) every day to maintain the necessary level of medication in your body.

Don’t suddenly stop taking Lexapro; this could lead to uncomfortable withdrawal symptoms or worsened depression.

It’s important to maintain the same level of medication in your body, so if you miss a dose, take it as soon as you remember. If it’s almost time for your next dose, skip the missed dose and resume your regular schedule. Don’t take an extra dose to make up for a missed one.

What Precautions Should I Take With Escitalopram?

Before taking escitalopram, speak with your doctor and follow these special precautions:

  • Allergy and ingredient check. Inform your doctor if you’re allergic to escitalopram, citalopram (Celexa), or any ingredients in escitalopram.
  • Monoamine oxidase inhibitor (MAOI) caution. Before taking escitalopram, disclose if you’ve taken MAOIs like isocarboxazid or phenelzine in the last two weeks.
  • Medication review. Discuss all medications you’re taking or plan to take with your doctor, including any changes while on escitalopram. Do not take escitalopram with citalopram because they are similar SSRIs. Inform your doctor about any nonprescription drugs or herbal products you’re using, such as aspirin, ibuprofen, naproxen, St. John’s wort, or tryptophan.
  • Discuss your health history. Tell your doctor about any conditions like low sodium levels, alcohol or drug use history, recent heart attacks, bleeding problems, seizures, glaucoma, or liver, kidney, or heart disease.
  • Pregnancy and breastfeeding caution. If you are pregnant, planning to become pregnant, or breastfeeding, discuss it with your doctor. Escitalopram can be used during pregnancy if the benefits outweigh the risks, but there is a potential risk for neonatal adaptation syndrome if used late in pregnancy.
  • Breastfeeding caution. Escitalopram is generally considered safe for breastfed infants, but the decision should be made after a careful risk-benefit analysis by a healthcare provider.
  • Surgery notification. Let your doctor or dentist know you’re taking escitalopram if you have any surgery planned, including dental procedures. This medication can affect the way anesthesia works.
  • Learn about escitalopram’s effects. Be sure you discuss all side effects with your doctor. Understand that this medication can cause drowsiness and impair your judgment.
  • Risk of glaucoma. Escitalopram may cause or worsen angle-closure glaucoma. Consider having an eye exam before starting this medication, and seek immediate medical help if you experience symptoms like eye pain or vision changes.
