PRESCRIPTION: Yes

GENERIC AVAILABLE: Yes

PREPARATIONS: Tablets: 5, 10 and 20 mg. Solution: 1 mg/ml

STORAGE: Escitalopram should be stored at room temperature, 15 C to 30 C (59 F to 86 F)

PRESCRIBED FOR: Escitalopram 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 escitalopram is not approved for these purposes.

DOSING: The usual starting dose of escitalopram 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. Escitalopram can be taken with or without food.

DRUG INTERACTIONS: All SSRIs, including escitalopram, 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 escitalopram before starting an MAO inhibitor. Conversely, at least 14 days should elapse after discontinuing an MAO inhibitor before starting escitalopram. Similar reactions occur when SSRIs are combined with other drugs, for example, tryptophan, St. John's wort, meperidine (Demerol), lithium (Lithobid, Eskalith), triptans (for example, sumatriptan [Imitrex, Alsuma]), and tramadol (Ultram) that increase serotonin in the brain.

Use of selective serotonin inhibitors may increase the risk of gastrointestinal bleeding in patients taking warfarin (Coumadin), aspirin, nonsteroidal antiinflammatory drugs, and other drugs that cause bleeding.
