What is Lexapro?

Lexapro (escitalopram) is an antidepressant belonging to a group of drugs called selective serotonin reuptake inhibitors (SSRIs). Escitalopram affects the levels of certain chemicals in the brain that may be altered in people suffering from depression or anxiety.

Lexapro is used to treat major depressive disorder in adults and adolescents at least 12 years old.

Lexapro is also used to treat anxiety in adults.

Warnings

You should not use Lexapro if you also take pimozide or citalopram (Celexa).

Do not use Lexapro within 14 days before or 14 days after you have used an MAO inhibitor, such as isocarboxazid, linezolid, methylene blue injection, phenelzine, rasagiline, selegiline, or tranylcypromine.

Some young people have thoughts about suicide when first taking an antidepressant. Stay alert to changes in your mood or symptoms. Report any new or worsening symptoms to your doctor.

Seek medical attention right away if you have symptoms of serotonin syndrome, such as: agitation, hallucinations, fever, sweating, shivering, fast heart rate, muscle stiffness, twitching, loss of coordination, nausea, vomiting, or diarrhea.

Do not give Lexapro to anyone under 12 years.

Before taking this medicine

You should not use Lexapro if you are allergic to escitalopram or citalopram (Celexa), or if:

  • you also take pimozide or citalopram.

Be sure your doctor knows if you also take stimulant medicine, opioid medicine, herbal products, or medicine for depression, mental illness, Parkinson's disease, migraine headaches, serious infections, or prevention of nausea and vomiting.

Lexapro is not approved for use by anyone younger than 12 years old.

Ask your doctor about taking this medicine if you are pregnant. Taking an SSRI antidepressant during late pregnancy may cause serious medical complications in the baby. However, you may have a relapse of depression if you stop taking your antidepressant. Tell your doctor right away if you become pregnant. Do not start or stop taking Lexapro without your doctor's advice.

If you are pregnant, your name may be listed on a pregnancy registry to track the effects of escitalopram on the baby.

If you are breastfeeding, tell your doctor if you notice drowsiness, agitation, feeding problems, or poor weight gain in the nursing baby.
