Warnings and Precautions

There are some severe side effects of Lexapro that you should look out for and discuss with your doctor to avoid any unnecessary risks.

  • Suicidal thoughts and behavior in adolescents and young adults. Lexapro can worsen suicidal ideation and lead to self-destructive behaviors in adults up to 24 years old and younger patients, hence needing close monitoring of treatment in this age group.
  • Serotonin syndrome. It is a potentially dangerous condition that has been linked to the use of SNRIs and SSRIs, including Lexapro. This risk is further increased when Lexapro is taken in combination with other serotonergic agents such as tricyclic antidepressants, fentanyl, triptans, tryptophan, tramadol, buspirone, St. John’s Wort, and amphetamines. It is important to be aware of the symptoms of serotonin syndrome (raised temperature, hypertension, increased heart rate, dizziness, flushing) and to discontinue Lexapro immediately and seek medical attention if they occur.
  • Discontinuation of treatment with Lexapro. Withdrawal symptoms (restlessness, insomnia, dizziness, sweating irritation, confusion, and stomach problems) can be prevented by slowly reducing the dosage of Lexapro when discontinuing treatment, under the guidance of a doctor.
  • Activation of mania/hypomania. Patients with bipolar disorder should be screened before prescribing Lexapro to prevent the potential risk of mania or hypomania activation.
  • Seizures. Patients with a history of seizures should be prescribed Lexapro with caution to avoid the potential risk.
  • Abnormal bleeding. Caution should be exercised for patients taking Lexapro with warfarin, aspirin, NSAIDs, or other medications that affect blood clotting.
  • Angle-closure glaucoma. Patients with increased eye pressure due to untreated narrow anterior chamber angles are at risk of angle-closure glaucoma when treated with Lexapro.
  • Hyponatremia or low sodium levels. It can occur in association with the syndrome of inappropriate antidiuretic hormone (SIADH) secretion, particularly in elderly patients.
  • Effects on cognitive and motor performance. Be careful when driving or operating machinery when on Lexapro.
  • Having concomitant illness. Patients with certain medical conditions or disorders that can affect metabolism or cardiovascular function should be cautious when using Lexapro.
  • Sexual dysfunction. It can occur when the patient is taking Lexapro.
  • Use in pregnancy. Treatment with Lexapro can cause lung problems and feeding difficulties in the newborn, especially when used later in pregnancy.

Do not suffer in silence trying to manage your symptoms alone. Prioritize your mental health and seek the support you need.

How long do Lexapro side effects last


Lexapro should not be used in the following situations:

  • Recent use of MAOIs. Avoid using MAOIs with Lexapro or within 14 days before or after stopping Lexapro as it increases the risk of serotonin syndrome. Also, do not start Lexapro if currently using linezolid or intravenous methylene blue.
  • Having hypersensitivity to escitalopram, citalopram, or any of the medication’s inactive ingredients.
  • Pimozide (an antipsychotic medication). Avoid using it concurrently.

Factors that Affect the Duration of Escitalopram Side Effects

How long do Lexapro side effects last? It can vary depending on several factors:

  1. Dosage. The dosage of Lexapro can significantly affect the occurrence and severity of side effects. Higher doses may increase the likelihood and intensity of adverse effects.
  2. Duration of treatment. Long-term use of Lexapro may cause more or different side effects than short-term use.
  3. Individual differences. Every person is different, so their body may respond differently to medications. Some individuals may be more susceptible to certain side effects than others.
  4. Age. Age can be a significant factor in the likelihood and intensity of side effects experienced with Lexapro. Older individuals may experience more side effects than younger individuals.
  5. Underlying health conditions. Individuals with certain underlying health conditions may experience more side effects than others. It is important to discuss your medical history with your healthcare provider before starting Lexapro.
  6. Other medications. Concurrent use of other medicines that can interact with Lexapro may lead to more or fewer side effects. It is essential to disclose all medications, including over-the-counter drugs, to your healthcare provider to avoid harmful drug interactions.
  7. Withdrawal. Stopping Lexapro abruptly can result in withdrawal symptoms, including dizziness, headache, and nausea. Do not quit taking this medication without professional assistance.

It is crucial to discuss any concerns or side effects experienced while taking Lexapro with your healthcare provider, as they can determine the appropriate course of action.


While Lexapro can be an effective treatment for depression and anxiety, it may cause a range of common and rare side effects. By being informed about the potential risks of Lexapro, you can better understand what to expect and take steps to manage any side effects that may arise.
