Escitalopram is an antidepressant medication that works in the brain. It is approved for the treatment of major depressive disorder (MDD) and generalized anxiety disorder (GAD).
Symptoms of depression include:
Generalized anxiety disorder (GAD) occurs when a person experiences excessive anxiety or worry for at least six months. Other symptoms include
Escitalopram may also be helpful when prescribed “off-label” for obsessive compulsive disorder (OCD), eating disorders such as binge eating disorder or bulimia nervosa, panic disorder, posttraumatic stress disorder (PTSD), social phobia, and premenstrual dysphoric disorder (PMDD). “Off-label” means that it hasn’t been approved by the Food and Drug Administration for this condition. Your mental health provider should justify his or her thinking in recommending an “off-label” treatment. They should be clear about the limits of the research around that medication and if there are any other options.
Do not stop taking escitalopram, even when you feel better. With input from you, your health care provider will assess how long you will need to take the medicine.
Missing doses of escitalopram may increase your risk for relapse in your symptoms.
Stopping escitalopram abruptly may result in one or more of the following withdrawal symptoms: irritability, nausea, feeling dizzy, vomiting, nightmares, headache, and/or paresthesias (prickling, tingling sensation on the skin).
Depression is also a part of bipolar illness. People with bipolar disorder who take antidepressants may be at risk for “switching” from depression into mania. Symptoms of mania include “high” or irritable mood, very high self-esteem, decreased need for sleep, pressure to keep talking, racing thoughts, being easily distracted, frequently involved in activities with a large risk for bad consequences (for example, excessive buying sprees).
Medical attention should be sought if serotonin syndrome is suspected. Please refer to serious side effects for signs/symptoms.
If you are planning on becoming pregnant, notify your health care provider to best manage your medications. People living with MDD who wish to become pregnant face important decisions. Untreated MDD has risks to the fetus, as well as the mother. It is important to discuss the risks and benefits of treatment with your doctor and caregivers. For women who take antidepressant medications during weeks 13 through the end of their pregnancy (second and third trimesters), there is a risk that the baby can be born before it is fully developed (before 37 weeks).
For mothers who have taken SSRIs during their pregnancy, there appears to be less than a 1% chance of infants developing persistent pulmonary hypertension. This is a potentially fatal condition that is associated with use of the antidepressant in the second half of pregnancy. However, women who discontinued antidepressant therapy were five times more likely to have a depression relapse than those who continued their antidepressant. If you are pregnant, please discuss the risks and benefits of antidepressant use with your health care provider.
Caution is advised with breastfeeding since escitalopram does pass into breast milk.
Escitalopram is usually taken one time per day with or without food.
Typically patients begin at a low dose of medicine and the dose is increased slowly over several weeks.
The dose usually ranges from 10 mg to 20 mg. Only your health care provider can determine the correct dose for you.
The liquid should be measured with a dosing spoon or oral syringe which you can get from your pharmacy.
If you are taking escitalopram, you should not take other medications that include citalopram (Celexa®).
Consider using a calendar, pillbox, alarm clock, or cell phone alert to help you remember to take your medication. You may also ask a family member or friend to remind you or check in with you to be sure you are taking your medication.
If you miss a dose of escitalopram, take it as soon as you remember, unless it is closer to the time of your next dose. Discuss this with your health care provider. Do not double your next dose or take more than what is prescribed.
Avoid drinking alcohol or using illegal drugs while you are taking antidepressant medications. They may decrease the benefits (e.g., worsen your condition) and increase adverse effects (e.g., sedation) of the medication.
If an overdose occurs, call your doctor or 911. You may need urgent medical care. You may also contact the poison control center at 1-800-222-1222.
A specific treatment to reverse the effects of escitalopram does not exist.
Common side effects
Headache, nausea, diarrhea, dry mouth, increased sweating, feeling nervous, restless, fatigue, or having trouble sleeping (insomnia). These will often improve over the first week or two as you continue to take the medication.
Sexual side effects, such as problems with orgasm or ejaculatory delay often do not diminish over time.
Rare/serious side effects
Low sodium blood levels (symptoms of low sodium levels may include headache, weakness, difficulty concentrating and remembering), teeth grinding, angle closure glaucoma (symptoms of angle closure glaucoma may include eye pain, changes in vision, swelling or redness in or around eye), serotonin syndrome (symptoms may include shivering, diarrhea, confusion, severe muscle tightness, fever, seizures, and death), seizure
SSRI antidepressants including escitalopram may increase the risk of bleeding events. Combined use of aspirin, nonsteroidal anti-inflammatory drugs (e.g., ibuprofen, naproxen), warfarin, and other anti-coagulants may increase this risk. This may include symptoms such as gums that bleed more easily, nose bleed, or gastrointestinal bleeding. Some cases have been life threatening.
To date, there are no known problems associated with long term use of escitalopram. It is a safe and effective medication when used as directed.
Escitalopram should not be taken with or within 2 weeks of taking monoamine oxidase inhibitors (MAOIs). These include phenelzine (Nardil®), tranylcypromine (Parnate®), isocarboxazid (Marplan®), rasagiline (Azilect®), and selegiline (Emsam®).
Citalopram should not be taken with pimozide, a medication usually used to treat Tourette syndrome.
Although rare, there is an increased risk of serotonin syndrome when escitalopram is used with other medications that increase serotonin, such as other antidepressants, migraine medications called “triptans” (e.g., Imitrex®), some pain medications (e.g., tramadol (Ultram®), the antibiotic linezolid (Zyvox®), and amphetamines.
Escitalopram may increase the effects of other medications that can cause bleeding (e.g., ibuprofen (Advil®, Motrin®), warfarin (Coumadin®) and aspirin).
Sleep, energy, or appetite may show some improvement within the first 1-2 weeks. Improvement in these physical symptoms can be an important early signal that the medication is working. Depressed mood and lack of interest in activities may need up to 6-8 weeks to fully improve.
Suicidal Thoughts or Actions in Children and Adults
Depression and certain other psychiatric disorders are themselves associated with increases in the risk of suicide. Patients with major depressive disorder (MDD), both adult and pediatric, may experience worsening of their depression and/or the emergence of suicidal ideation and behavior (suicidality) or unusual changes in behavior, whether or not they are taking antidepressant medications. This risk may persist until significant remission occurs.
In short-term studies, antidepressants increased the risk of suicidality in children, adolescents, and young adults when compared to placebo. Short-term studies did not show an increase in the risk of suicidality with antidepressants compared to placebo in adults beyond age 24. Adults age 65 and older taking antidepressants have a decreased risk of suicidality. Patients, their families, and caregivers should be alert to the emergence of anxiety, restlessness, irritability, aggressiveness and insomnia. If these symptoms emerge, they should be reported to the patient’s prescriber or health care professional. All patients being treated with antidepressants for any indication should watch for and notify their health care provider for worsening symptoms, suicidality and unusual changes in behavior, especially during the first few months of treatment.
