Lexapro (escitalopram) is an SSRI antidepressant medication related to Celexa. It may be prescribed for the treatment of depressive disorders, anxiety disorders, and other mood disorders, sometimes in combination with other medications.

Common Side Effects of Lexapro

Common side effects include nausea, sleepiness, weakness, dizziness, anxiety, trouble sleeping, sexual problems, sweating, shaking, loss of appetite, dry mouth, and bowel changes. It's important to know that many side effects go away during treatment as your body adjusts to the medicine.

While these side effects usually do not require medical intervention, you should report them to your healthcare provider if they continue for over 1 week, or if they interfere with your daily routine. Your doctor may decide to adjust your dosage or switch you to another medication entirely.

Also, you may experience other less common side effects. If you do, alert your doctor. You should never stop or change the dosage of your medication on your own.

Potentially Serious Side Effects

If you experience any of the following side effects, you should contact your healthcare provider immediately, or seek emergency medical care.

  • Increased risk of bleeding: Symptoms may include bleeding or bruising — more likely to occur if also on a blood thinner or nonsteroidal anti-inflammatory (NSAID)
  • Manic episode: Severely increased energy, trouble sleeping, racing thoughts, reckless behavior like excessive gambling or shopping, inflated sense of self, rapid speech, or feeling extremely happy or irritable
  • Serotonin syndrome: Agitation, hallucinations, confusion, coma, coordination or balance problems, muscle twitching, racing heartbeat, high or low blood pressure, sweating, fever, nausea, vomiting, or diarrhea
  • Severe allergic reaction: Rash, difficulty breathing, fever, joint pain, or swelling of the mouth, lips, eyes, or tongue
  • Suicidal thoughts: Thinking of suicide or making attempts at suicide seek treatment right away
  • Additional side effects: Seizures, change in appetite or weight, or low blood sodium levels

If you are having suicidal thoughts, contact the National Suicide Prevention Lifeline at 1-800-273-8255 for support and assistance from a trained counselor. If you or a loved one are in immediate danger, call 911.

Possible Side Effects of Withdrawal

It's never a good idea to stop your medication abruptly. Stopping Lexapro may cause some withdrawal symptoms, such as:

  • Alteration in sleep habits
  • Anxiety
  • Confusion
  • Dizziness
  • Electric shock-like sensations
  • Headache
  • High or low mood
  • Irritability
  • Nausea
  • Restlessness
  • Shaking
  • Sweating


This list is not intended to be all-inclusive or to replace information provided by your doctor. A number of other side effects for both usage and withdrawal have been reported by the public. If you notice any other effects, check with your doctor.

Remember to consult your healthcare provider anytime you’re unsure about any symptoms that you experience while taking any medication. Most of the time, particularly in the case of antidepressants, other medications are available when serious or bothersome side effects occur. Be good to yourself. Take your medications and be safe.
