Escitalopram is an antidepressant belonging to a group of drugs called selective serotonin reuptake inhibitors (SSRIs). It affects chemicals in the brain that may be unbalanced in people with depression or anxiety.

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

Escitalopram is also used to treat anxiety in adults.

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.

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 this medicine 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.

Research has shown approximately 40% of people taking antidepressants such as Lexapro will gain 7% or more of their starting body weight. The weight gain experienced with Lexapro is a lot less than that reported with other antidepressants such as paroxetine, mirtazapine, or doxepin but more than fluoxetine. Continue reading
