Escitalopram is used to treat depression and generalized anxiety disorder (GAD). It is an antidepressant that belongs to a group of medicines known as selective serotonin reuptake inhibitors (SSRIs). These medicines work by increasing the activity of the chemical serotonin in the brain.

This medicine is available only with your doctor's prescription.

Take this medicine only as directed by your doctor to benefit your condition as much as possible. Do not take more of it, do not take it more often, and do not take it for a longer time than your doctor ordered.

This medicine should come with a Medication Guide. Read and follow these instructions carefully. Ask your doctor or pharmacist if you have any questions.

Escitalopram may be taken with or without food. If your doctor tells you to take it at a specific time, follow your doctor's instructions.

If you are using the oral liquid, shake the bottle well before measuring each dose. Use a marked measuring spoon, oral syringe, or medicine cup to measure each dose. The average household teaspoon may not hold the right amount of liquid.

You may have to take escitalopram for a month or longer before you begin to feel better.

It is very important that your doctor check your progress at regular visits to allow for changes in your dose and to help reduce any side effects. Blood tests may be needed to check for any unwanted effects.

Do not take escitalopram with a monoamine oxidase (MAO) inhibitor (eg, isocarboxazid [Marplan®], linezolid (Zyvox®), methylene blue injection, phenelzine [Nardil®], selegiline [Eldepryl®], tranylcypromine [Parnate®]). Do not start taking escitalopram during the 2 weeks after you stop a MAO inhibitor and wait 2 weeks after stopping escitalopram before you start taking a MAO inhibitor. If you take them together or do not wait 2 weeks, you may develop confusion, agitation, restlessness, stomach or intestinal symptoms, a sudden high body temperature, an extremely high blood pressure, or severe convulsions.

Do not take escitalopram with pimozide (Orap®). Using these medicines together can cause very serious heart problems.

Escitalopram may cause some teenagers and young adults to be agitated, irritable, or display other abnormal behaviors. It may also cause some people to have suicidal thoughts and tendencies or to become more depressed. Some people may have trouble sleeping, get upset easily, have a big increase in energy, or start to act reckless. If you or your caregiver notice any of these unwanted effects, tell your doctor right away. Let the doctor know if you or anyone in your family has bipolar disorder (manic-depressive) or has tried to commit suicide.

Escitalopram may cause a serious condition called serotonin syndrome if taken together with some medicines. Do not use escitalopram with buspirone (Buspar®), fentanyl (Abstral®, Duragesic®), lithium (Eskalith®, Lithobid®), tryptophan, St. John's wort, amphetamines, or some pain or migraine medicines (eg, rizatriptan, sumatriptan, tramadol, Frova®, Imitrex®, Maxalt®, Relpax®, Ultram®, Zomig®). Check with your doctor first before taking any other medicines with escitalopram.

Do not suddenly stop taking this medicine without checking first with your doctor. Your doctor may want you to gradually reduce the amount you are taking before stopping it completely. This will decrease the chance of having withdrawal symptoms such as increased anxiety, burning or tingling feelings, confusion, dizziness, headache, irritability, nausea, trouble sleeping, or unusual tiredness or weakness.

This medicine may increase your risk for bleeding problems. Make sure your doctor knows if you are also taking other medicines that thin the blood, such as aspirin, nonsteroidal antiinflammatory agents, also called NSAIDs (eg, diclofenac, ibuprofen, naproxen, Advil®, Aleve®, Celebrex®, Voltaren®), or warfarin (Coumadin®, Jantoven®).

This medicine may cause hyponatremia (low sodium in the blood). This is more common in elderly patients, those who are taking diuretic medicines for high blood pressure, or those who have decreased amounts of fluid in the body due to severe diarrhea or vomiting. Check with your doctor right away if you have confusion, headache, memory problems, trouble concentrating, weakness, or unsteadiness.

This medicine may cause some people to become drowsy, to have trouble with thinking or controlling body movements. Make sure you know how you react to escitalopram before you drive, use machines, or do anything else that could be dangerous if you are not alert or well-coordinated.

The use of alcohol is not recommended in patients who are taking escitalopram.

Do not take other medicines unless they have been discussed with your doctor. This includes prescription or nonprescription (over-the-counter [OTC]) medicines and herbal or vitamin supplements.
