    Lexapro Precautions

    Lexapro and other antidepressant medicines may cause serious side effects, including:

    1. Suicidal thoughts or actions:

    • Lexapro and other antidepressant medicines may increase suicidal thoughts or actions in some children, teenagers, or young adults within the first few months of treatment or when the dose is changed.
    • Depression or other serious mental illnesses are the most important causes of suicidal thoughts or actions.
    • Watch for these changes and call your healthcare provider right away if you notice:
      • New or sudden changes in mood, behavior, actions, thoughts, or feelings, especially if severe.
      • Pay particular attention to such changes when Lexapro is started or when the dose is changed.

    Keep all follow-up visits with your healthcare provider and call between visits if you are worried about symptoms.

    Call your healthcare provider right away if you have any of the following symptoms, or call 911 if an emergency, especially if they are new, worse, or worry you:

    • attempts to commit suicide
    • acting on dangerous impulses
    • acting aggressive or violent
    • thoughts about suicide or dying
    • new or worse depression
    • new or worse anxiety or panic attacks
    • feeling agitated, restless, angry or irritable
    • trouble sleeping
    • an increase in activity or talking more than what is normal for you
    • other unusual changes in behavior or mood

    Call your healthcare provider right away if you have any of the following symptoms, or call 911 if an emergency. Lexapro may be associated with these serious side effects:

    2. Serotonin Syndrome or Neuroleptic Malignant Syndrome-like reactions. This condition can be life-threatening and may include:

    • agitation, hallucinations, coma or other changes in mental status
    • coordination problems or muscle twitching (overactive reflexes)
    • racing heartbeat, high or low blood pressure
    • sweating or fever
    • nausea, vomiting, or diarrhea
    • muscle rigidity

    3. Severe allergic reactions:

    • trouble breathing
    • swelling of the face, tongue, eyes or mouth
    • rash, itchy welts (hives) or blisters, alone or with fever or joint pain

    4. Abnormal bleeding: Lexapro and other antidepressant medicines may increase your risk of bleeding or bruising, especially if you take the blood thinner warfarin (Coumadin, Jantoven), a non-steroidal anti-inflammatory drug (NSAIDs, like ibuprofen or naproxen), or aspirin.

    5. Seizures or convulsions

    6. Manic episodes:

    • greatly increased energy
    • severe trouble sleeping
    • racing thoughts
    • reckless behavior
    • unusually grand ideas
    • excessive happiness or irritability
    • talking more or faster than usual

    7. Changes in appetite or weight. Children and adolescents should have height and weight monitored during treatment.

    8. Low salt (sodium) levels in the blood. Elderly people may be at greater risk for this. Symptoms may include:

    • headache
    • weakness or feeling unsteady
    • confusion, problems concentrating or thinking or memory problems

    Do not stop Lexapro without first talking to your healthcare provider. Stopping Lexapro too quickly may cause serious symptoms including:

    • anxiety, irritability, high or low mood, feeling restless or changes in sleep habits
    • headache, sweating, nausea, dizziness

    Do not take Lexapro if you:

    • are allergic to Lexapro (escitalopram) or citalopram (Celexa) or any of the ingredients in Lexapro.
    • take a Monoamine Oxidase Inhibitor (MAOI). Ask your healthcare provider or pharmacist if you are not sure if you take an MAOI, including the antibiotic linezolid.
      • Do not take an MAOI within 14 days of stopping Lexapro.
      • Do not start Lexapro if you stopped taking an MAOI in the last 14 days.

    People who take Lexapro close in time to an MAOI may have serious or even life-threatening side effects. Get medical help right away if you have any of these symptoms:

    • high fever
    • uncontrolled muscle spasms
    • stiff muscles
    • rapid changes in heart rate or blood pressure
    • confusion
    • loss of consciousness (pass out)
    • take the antipsychotic medicine pimozide (Orap) because taking this drug with Lexapro can cause serious heart problems.

    Lexapro FDA Warning


    Antidepressants increased the risk compared to placebo of suicidal thinking and behavior (suicidality) in children, adolescents and young adults in short-term studies of major depressive disorder (MDD) and other psychiatric disorders. Anyone considering the use of Lexapro tablets or any other antidepressant in a child, adolescent or young adult must balance this risk with the clinical need. Short-term studies did not show an increase in the risk of suicidality with antidepressants compared to placebo in adults beyond age 24; there was a reduction in risk with antidepressants compared to placebo in adults aged 65 and older. Depression and certain other psychiatric disorders are themselves associated with increases in the risk of suicide. Patients of all ages who are started on antidepressant therapy should be monitored appropriately and observed closely for clinical worsening, suicidality or unusual changes in behavior. Families and caregivers should be advised of the need for close observation and communication with the prescriber. Lexapro tablets are not approved for use in pediatric patients less than 12 years of age.
