What is escitalopram?

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.

Warnings

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

Do not use escitalopram 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 stop using escitalopram without first asking your doctor.

Before taking this medicine

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

• you also take pimozide.

Do not use escitalopram within 14 days before or 14 days after you have used an MAO inhibitor. A dangerous drug interaction could occur. MAO inhibitors include isocarboxazid, linezolid, phenelzine, rasagiline, selegiline, and tranylcypromine.

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. These medicines may interact with escitalopram and cause a serious condition called serotonin syndrome.

To make sure escitalopram is safe for you, tell your doctor if you have ever had:

• liver or kidney disease;

• seizures;

• low levels of sodium in your blood;

• heart disease, high blood pressure;

• a stroke;

• bleeding problems;

Some young people have thoughts about suicide when first taking an antidepressant. Your doctor should check your progress at regular visits. Your family or other caregivers should also be alert to changes in your mood or symptoms.

Escitalopram 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 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.

How should I take escitalopram?

Take escitalopram at the same time each day, with or without food.

Measure liquid medicine carefully. Use the dosing syringe provided, or use a medicine dose-measuring device (not a kitchen spoon).

It may take up to 4 weeks before your symptoms improve. Keep using the medication as directed and tell your doctor if your symptoms do not improve.

Tell your doctor if you have any changes in sexual function, such as loss of interest in sex, trouble having an orgasm, or (in men) problems with erections or ejaculation. Some sexual problems can be treated.
