What is Lexapro (escitalopram)? Uses, dosage and side effects

Lexapro (escitalopram) is an antidepressant of the selective serotonin reuptake inhibitor group, which helps maintain mental balance by increasing the amount of serotonin in the brain. Although it primarily treats depression and anxiety, it can also work for panic attacks. Lexapro is a prescribed medication that must be used under the supervision of a doctor. Only the doctor can decide the dose changes and when to quit. Compared to other antidepressants, it has less side effects and is easily tolerated. Nevertheless, nausea, anxiety, weight gain, dizziness, weakness and dry mouth are among the main side effects.

Lexapro (Escitalopram) is an antidepressant medication, which can be obtained with a prescription. It belongs to group of the selective serotonin reuptake inhibitors (SSRI). It increases the amount of serotonin (happiness hormone) that helps maintain mental balance.

What is Lexapro used for?

Indications for Lexapro

  • Treatment of obsessive-compulsive disorder

How does Lexapro work?

This medication belongs to a group called selective serotonin reuptake inhibitors (SSRI). The way how medications in this group work are similar and they treat similar conditions. Escitalopram increases the amount of serotonin (happiness hormone) in the brain and helps maintain mental balance. (2)

Serotonin is a hormone naturally produced in the brain that has positive effects on emotions and behaviors when it is secreted in sufficient quantity. Lack of serotonin can cause mental problems such as depression or anxiety. (3)

What conditions is Lexapro used to treat?

Lexapro for depression

Lexapro is mostly prescribed to treat major depressive disorder. This drug increases the activity of serotonin in the central nervous system with a quite strong effect. The probability of interacting with other drugs and its side effects are considered low.

In a randomized study to assess the power of escitalopram in the treatment of depression, the medication was observed to be more effective than and equal to other SSRIs and serotonin-noradrenaline reuptake inhibitors. In addition, escitalopram can prevent recurrence of depression in a long-term use. (4)

Lexapro for anxiety

In another study, the efficacy and tolerability of escitalopram in the treatment of generalized anxiety disorder were assessed. According to this study, development and improvement were observed in the group using escitalopram compared to the group using placebo (ineffective drug). In addition, it was well tolerated by the patients and the side effects were scaled as low. (5)

Lexapro for chronic pain

In recent years, SSRI group medications have been used in the treatment of chronic pain in addition to depression treatment due to their low side effects. In a study with drug addicts, escitalopram has been observed to decrease pain intensity.

Additionally, in a review evaluating the results of 36 studies, escitalopram was found to be significantly effective in the treatment of chronic pain compared to other drugs. However, more studies should be done on this subject. (6, 7)
