Understanding Depression Slideshow

GENERIC NAME: escitalopram BRAND NAME: Lexapro LEXAPRO USES: Lexapro is approved for the treatment of depression and generalized anxiety disorder.Drugs in the SSRI class also are used for treating obsessive compulsive disorders and panic disorders, although Lexapro is not approved for these purposes.PRESCRIPTION: Yes GENERIC AVAILABLE: Yes LEXAPRO SIDE EFFECTS WARNING: Some patients experience withdrawal reactions upon stopping SSRI therapy. Symptoms may include dizziness, tingling, tiredness, vivid dreams, irritability, or poor mood. In order to avoid these symptoms, the dose of SSRI can be slowly reduced instead of abruptly stopped.Antidepressants increased the risk of suicidal thinking and behavior (suicidality) in short-term studies in children and adolescents with depression and other psychiatric disorders. Anyone considering the use of Lexapro or any other antidepressant in a child or adolescent must balance this risk with the clinical need. Short-term studies did not show an increase in the risk of suicidality with antidepressants compared with placebo in adults beyond 24 years of age. There was a reduction in risk of suicidality with antidepressants compared with placebo in adults 65 years of age and older. Depression and certain other psychiatric disorders are themselves associated with increases in the risk of suicide. Patients who are started on therapy with antidepressants should be closely observed for clinical worsening, suicidality, or unusual changes in behavior.LEXAPRO SIDE EFFECTS: Common side effects associated with Lexapro are agitation or restlessness, blurred vision, diarrhea, difficulty sleeping, drowsiness, dry mouth, fever, frequent urination, headache, indigestion, nausea, increased or decreased appetite,increased sweating, sexual difficulties (decreased sexual ability or desire, ejaculatory delay), taste alterations, tremor (shaking), and weight changes. Other side effects include influenza-like symptoms andpain in neck or shoulders.Although changes in sexual desire, sexual performance, and sexual satisfaction often occur as a result of depression itself, they also may be a consequence of the drugs used to treat depression. In particular, about one in 11 men given Lexapro report difficulties ejaculating. Possible serious side effects of Lexapro include: Serotonin syndromeSuicidal thinking and behaviorAbnormal bleedingSeizuresManic episodesLow sodiumAngle closure glaucomaLEXAPRO DOSAGE: The usual starting dose of Lexapro for treating depression in adults or adolescents is 10 mg once daily in the morning or evening. The dose may be increased to 20 mg once daily after 1 week. Benefit may not be seen until treatment has been given for up to 4 weeks. A daily dose of 20 mg may not be more effective than 10 mg daily for treatment of depression. The dose for treating generalized anxiety disorder is 10 mg once daily. Lexapro can be taken with or without food.LEXAPRO AND DRUG INTERACTIONS: All SSRIs, including Lexapro, should not be combined with drugs in the monoamine oxidase (MAO) inhibitor class of antidepressants such as isocarboxazid (Marplan), phenelzine (Nardil), tranylcypromine (Parnate), selegiline (Eldepryl) and procarbazine (Matulane) or other drugs that inhibit monoamine oxidase such as linezolid (Zyvox) and intravenous methylene blue. Such combinations may lead to confusion, high blood pressure, high fevers, tremor or muscle rigidity, and increased activity. At least 14 days should elapse after discontinuing Lexapro before starting an MAO inhibitor. Conversely, at least 14 days should elapse after discontinuing an MAO inhibitor before starting Lexapro. Similar reactions occur when SSRIs are combined with other drugs that increase serotonin in the brain, for example tryptophan, St. John's wort, meperidine (Demerol), lithium (Lithobid, Eskalith), triptans (for example, sumatriptan [Imitrex, Alsuma]), and tramadol (Ultram) Use of selective serotonin inhibitors may increase the risk of gastrointestinal bleeding in patients taking warfarin (Jantoven, Coumadin), aspirin, nonsteroidal anti-inflammatory drugs (NSAIDs), and other drugs that cause bleeding. LEXAPRO AND PREGNANCY AND BREASTFEEDING SAFETY: The safety of Lexapro during pregnancy and breastfeeding has not been established. Therefore, Lexapro should not be used during pregnancy unless, in the opinion of the physician, the expected benefits to a patient outweigh unknown hazards to the fetus.Lexapro is excreted in human milk. Lexapro should not be given to nursing mothers unless, in the opinion of the physician, the expected benefits to the patient outweigh the possible hazards to the child.LEXAPRO PREPARATIONS: Tablets: 5, 10 and 20 mg Solution: 1 mg/mlLEXAPRO STORAGE: Escitalopram should be stored at room temperature, 15 C to 30 C (59 F to 86 F) LEXAPRO DRUG CLASS AND MECHANISM: Escitalopram is an oral drug that is used for treating depression and generalized anxiety disorder. Chemically, escitalopram is similar to citalopram (Celexa). Both are in a class of drugs called selective serotonin reuptake inhibitors (SSRIs), a class that also includes fluoxetine (Prozac), paroxetine (Paxil) and sertraline (Zoloft). SSRIs work by affecting neurotransmitters in the brain, the chemical messengers that nerves use to communicate with one another. Neurotransmitters are made and released by nerves and then travel to other nearby nerves where they attach to receptors on the nerves. Not all of the neurotransmitter that is released binds to receptors and, instead, is taken up by the nerves that produced them. This is referred to as "reuptake." Many experts believe that an imbalance of neurotransmitters is the cause of depression. Escitalopram prevents the reuptake of one neurotransmitter, serotonin, an action which results in more serotonin in the brain to attach to receptors. The FDA approved escitalopram in August 2002.Medically reviewed by Eni Williams, PharmD
