PRESCRIPTION: Yes

PREPARATIONS: Tablets: 10, 20, and 40 mg. Solution: 10 mg/5 ml

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

PRESCRIBED FOR: Citalopram is used for the management of depression. Citalopram also is used for treating obsessive compulsive disorder (OCD), panic disorder, premenstrual dysphoric syndrome (PMDD), anxiety disorder, and posttraumatic stress disorder.

DOSING: The usual starting dose is 20 mg in the morning or evening. The dose may be increased to 40 mg daily after one week. A dose of 60 mg has not been shown to be more effective than 40 mg. As with all antidepressants, it may take several weeks of treatment before maximum effects are seen. Doses are often slowly adjusted upwards to find the most effective dose.

DRUG INTERACTIONS: All SSRIs, including citalopram, should not be taken with any of the mono-amine oxidase (MAO) inhibitor-class of antidepressants, for example, isocarboxazid (Marplan), phenelzine (Nardil), tranylcypromine (Parnate), selegiline (Eldepryl), and procarbazine (Matulane). Such combinations may lead to confusion, high blood pressure, tremor, and hyperactivity. If treatment is to be changed from citalopram to an MAOI or vice-versa, there should be a 14 day period without either drug before the alternative drug is started. Tryptophan, a common dietary supplement, can cause headaches, nausea, sweating, and dizziness when taken with any SSRI. Linezolid and intravenous methylene blue are also MAO inhibitors and should not be combined with citalopram.
