What You'll Learn
Lexapro and serotonin syndrome
Lexapro (escitalopram) is a selective serotonin reuptake inhibitor (SSRI) used to treat depression and anxiety. It is generally well-tolerated, with side effects comparable to other SSRIs. However, in rare cases, Lexapro has been associated with serotonin syndrome, a potentially life-threatening condition.
Serotonin syndrome occurs when there is an excessive accumulation of serotonin in the body. Serotonin is a chemical produced naturally by nerve cells in the brain, spinal cord, and intestines. It plays a crucial role in regulating attention, behaviour, body temperature, digestion, blood flow, and breathing. While typically well-tolerated, Lexapro may, in some rare cases, contribute to serotonin syndrome when combined with other serotonergic medications.
The syndrome typically occurs when patients take multiple serotonergic medications, such as an antidepressant with a migraine medication or an opioid pain medication. It can also be caused by an intentional overdose of antidepressants. Symptoms of serotonin syndrome range from mild to severe and include agitation, hallucinations, delirium, coma, rapid heartbeat, changes in blood pressure, dizziness, excessive sweating, flushing, high body temperature (hyperthermia), tremors, rigid muscles, muscle spasms or twitching, loss of coordination, seizures, nausea, vomiting, and diarrhea.
If you suspect serotonin syndrome, it is crucial to seek immediate medical attention, especially if symptoms are severe or rapidly worsening. The main treatment for serotonin syndrome is to stop taking the drug(s) causing the syndrome. It is important to discuss any other medications or supplements with your doctor before starting Lexapro to reduce the risk of serotonin syndrome.
While rare, Lexapro may also cause allergic reactions, and it is associated with an increased risk of bone fractures, especially in patients aged 50 years or older. Additionally, Lexapro may interact with other medications, such as monoamine oxidase inhibitors (MAOIs) and pimozide, increasing the risk of abnormal bleeding or serious heart problems, respectively.

Lexapro and seizures
Lexapro is a brand name for escitalopram, an antidepressant. It is prescribed to treat major depressive disorder (MDD) and generalized anxiety disorder (GAD). It is also prescribed to adolescents aged 12 to 17 for the treatment of MDD.
Lexapro has been associated with an increased risk of seizures in some patients. While the exact mechanism is not fully understood, it is believed that changes in brain chemistry and neuronal function may play a role. Some patients have reported experiencing seizures while taking Lexapro, even if they had no prior history of seizure disorders. It is important to note that the risk of seizures associated with Lexapro use is rare.
In one study, patients aged 20 to 64 years taking antidepressants were monitored for the development of epilepsy or seizures. The results showed that 0.37% of patients had a first diagnosis of epilepsy or seizures during the follow-up period, with an increased hazard ratio for all antidepressant drug classes. However, the risk of epilepsy or seizures was highest for certain specific antidepressants, such as trazodone, lofepramine, and venlafaxine, rather than Lexapro.
Additionally, Lexapro may cause adverse reactions when taken with other medications. For example, it should not be taken within 2 weeks of taking monoamine oxidase inhibitors (MAOIs) or in combination with the antipsychotic medication pimozide, as this can lead to serious heart problems. It is always important for patients to discuss any other medications or supplements they are taking with their doctor before starting Lexapro to reduce the risk of adverse reactions and side effects.
Other common side effects of Lexapro include nausea, diarrhea, dry mouth, sweating, insomnia, and dizziness. These side effects are typically mild and transient, improving within the first two weeks of taking the medication. However, it is important to consult a doctor if any concerning symptoms occur or if side effects persist or worsen.

Lexapro and discontinuation syndrome
Lexapro (escitalopram) is a prescription medication used to treat major depressive disorder and generalized anxiety disorder. Lexapro belongs to a category of drugs that have been associated with withdrawal symptoms after discontinuation, known as antidepressant discontinuation syndrome (ADS).
Abruptly stopping Lexapro is not advisable, and it is crucial to taper off the medication slowly under the guidance of a healthcare provider to minimize withdrawal symptoms. ADS symptoms typically begin within two to four days of stopping the medication and usually last less than two months. While ADS is generally not physically harmful, it can be very unpleasant, and the severity of symptoms can interfere with one's ability to fulfil responsibilities.
Common symptoms of Lexapro withdrawal include dizziness, muscle tension, chills, crying, brain fog, nausea, insomnia, fatigue, and flu-like symptoms such as headache, achiness, and sweating. More severe symptoms may include tremors, restless legs, uneven gait, difficulty coordinating speech and chewing movements, and mood swings, including agitation, anxiety, mania, depression, irritability, confusion, and paranoia.
It is important to note that not everyone will experience all of these symptoms, and the likelihood of experiencing severe withdrawal symptoms varies depending on the specific SSRI medication. In the case of Lexapro, research shows that about 46% of people experiencing withdrawal symptoms describe them as severe.
To minimize or prevent ADS, it is essential to work with a healthcare provider to gradually lower the dosage over weeks or months, sometimes substituting longer-acting drugs for shorter-acting medications. Support groups and online resources can also provide valuable information and peer support during the discontinuation process.

Lexapro and glaucoma
Lexapro is the brand name for escitalopram, a selective serotonin reuptake inhibitor (SSRI) used to treat depression and anxiety. SSRIs are one of the most commonly prescribed classes of antidepressants.
Glaucoma is the second leading cause of blindness globally. Iatrogenic glaucoma has been observed across disparate medication classes. Studies investigating the association between SSRI exposure and glaucoma have yielded mixed results.
A nationwide population-based study from Taiwan found that individuals receiving SSRIs were at greater risk of glaucoma incidence. The risk was higher for individuals receiving higher doses and longer durations of SSRI treatment. However, after adjusting for confounding variables, the increased likelihood of glaucoma was reduced. Subgroup analysis showed that the effect of SSRIs on glaucoma was limited to individuals younger than 65 years of age without diabetes.
Another study from Taiwan followed 26,186 newly diagnosed depression patients without pre-existing glaucoma, with half of the cohort using SSRIs for over a year. The study found no significant difference in the cumulative incidences of primary open-angle glaucoma (POAG) and primary angle-closure glaucoma (PACG) between the SSRI and non-SSRI cohorts. The overall incidence of POAG was slightly higher in the SSRI cohort, but the difference was not statistically significant.
A case report described a rare instance of a 45-year-old woman presenting with bilateral acute closed angle glaucoma (AACG) after discontinuing escitalopram. The patient exhibited symptoms such as severe headache, bilateral blurred vision, photophobia, and vomiting. Standard treatment for AACG was provided, and complete recovery was achieved within 24 hours.
While the relationship between Lexapro and glaucoma requires further investigation, it is important for clinicians to be aware of the potential risk of AACG associated with the discontinuation of escitalopram.

Lexapro and suicidal thoughts
Lexapro is the brand name for escitalopram, a Selective Serotonin Reuptake Inhibitor (SSRI) used to treat depression and anxiety. It is important to note that Lexapro can cause side effects in some people, and one of the most serious side effects is the emergence or worsening of suicidal thoughts and behaviours.
In a small number of cases, treatment with Lexapro has been associated with the onset of intense suicidal thoughts and actions. This phenomenon has been observed in patients with depression, and it is crucial for clinicians to inform patients and their families about this potential risk. If a patient experiences suicidal thoughts or tendencies while taking Lexapro, they should seek immediate medical help.
Several mechanisms have been proposed to explain the link between Lexapro and suicidal ideation. One theory suggests that the emergence of anxiety and akathisia (a condition characterised by restlessness and the inability to sit still) during the initial stages of treatment may contribute to the risk of suicidal behaviour. Another theory posits that SSRIs like Lexapro directly promote suicidal thoughts, leading to a cycle of pervasive and painful suicidal ideation. A third hypothesis relates to poor treatment adherence, particularly among adolescents, which can increase the risk of suicidal thoughts and actions.
It is important to note that the risk of suicidal thoughts and behaviours may be higher during the first few weeks of treatment with Lexapro. Regulatory bodies have issued warnings about this increased risk, and it is recommended that patients closely monitor their mental health during this initial period. Additionally, patients with bipolar disorder should exercise caution when taking Lexapro, as it may increase the risk of manic episodes.
While Lexapro can cause side effects like suicidal thoughts in some individuals, it is important to remember that many people may experience no side effects or only minor ones. These side effects often improve as the body adjusts to the medication, and they generally do not lead to treatment cessation. However, if you or someone you know is experiencing suicidal thoughts or tendencies while taking Lexapro, it is crucial to seek medical advice promptly.
