9 DRUG ABUSE AND DEPENDENCE

10 OVERDOSAGE The following have been reported with citalopram tablet overdosage: • Seizures, which may be delayed, and altered mental status including coma. • Cardiovascular toxicity, which may be delayed, including QRS and QTc interval prolongation, wide complex tachyarrhythmias, and torsade de pointes. Hypertension most commonly seen, but rarely can see hypotension alone or with co‐ingestants including alcohol. • Serotonin syndrome (patients with a multiple drug overdosage with other proserotonergic drugs may have a higher risk). Prolonged cardiac monitoring is recommended in citalopram overdosage ingestions due to the arrhythmia risk. Gastrointestinal decontamination with activated charcoal should be considered in patients who present early after a citalopram overdose. Consider contacting a Poison Center (1‐800‐221‐2222) or a medical toxicologist for additional overdosage management recommendations.

7 DRUG INTERACTIONS Table 5 presents clinically important drug interactions with citalopram. Table 5: Clinically Important Drug Interactions with Citalopram Monoamine Oxidase Inhibitors (MAOIs) Clinical Impact Concomitant use of SSRIs, including citalopram, and MAOIs increases the risk of serotonin syndrome. Intervention Citalopram is contraindicated in patients taking MAOIs, including MAOIs such as linezolid or intravenous methylene blue [see Dosage and Administration ( 2.5 ), Contraindications ( 4 ), Warnings and Precautions ( 5.3 )] . Pimozide Clinical Impact: Concomitant use of citalopram with pimozide increases plasma concentrations of pimozide, a drug with a narrow therapeutic index, and may increase the risk of QT prolongation and/or ventricular arrhythmias compared to use of citalopram alone [see Clinical Pharmacology ( 12.2 )]. Intervention: Citalopram is contraindicated in patients taking pimozide [see Contraindications ( 4 ), Warnings and Precautions ( 5.2 )]. Drugs that Prolong the QTc Interval Clinical Impact: Concomitant use of citalopram with drugs that prolong QT can cause additional QT prolongation compared to the use of citalopram alone [see Clinical Pharmacology ( 12.2 )]. Intervention: Avoid concomitant use of citalopram with drugs that prolong the QT interval (citalopram is contraindicated in patients taking pimozide) [see Contraindications ( 4 ), Warnings and Precautions ( 5.2 )]. CYP2C19 Inhibitors Clinical Impact: Concomitant use of citalopram with CYP2C19 inhibitors increases the risk of QT prolongation and/or ventricular arrhythmias compared to the use of citalopram alone [see Clinical Pharmacology ( 12.2 )]. Intervention: The maximum recommended dosage of citalopram is 20 mg daily when used concomitantly with a CYP2C19 inhibitor [see Dosage and Administration ( 2.4 ), Warnings and Precautions ( 5.2 )]. Serotonergic Drugs Clinical Impact: Concomitant use of citalopram and other serotonergic drugs increases the risk of serotonin syndrome. Intervention: Monitor patients for signs and symptoms of serotonin syndrome, particularly during citalopram initiation and dosage increases. If serotonin syndrome occurs, consider discontinuation of citalopram and/or concomitant serotonergic drugs [see Warning and Precautions ( 5.3 )]. Drugs That Interfere With Hemostasis (antiplatelet agents and anticoagulants) Clinical Impact: Concomitant use of citalopram and an antiplatelet or anticoagulant may potentiate the risk of bleeding. Intervention: Inform patients of the increased risk of bleeding associated with the concomitant use of citalopram and antiplatelet agents and anticoagulants. For patients taking warfarin, carefully monitor the international normalized ratio [see Warning and Precautions ( 5.4 )]. CYP2C19 Inhibitors : Citalopram tablets 20 mg daily is the maximum recommended dosage for patients taking concomitant CYP2C19 inhibitors ( 5.2 , 7 ) .

14 CLINICAL STUDIES The efficacy of citalopram as a treatment for major depressive disorder was established in two placebo-controlled studies (of 4 to 6 weeks duration) in adult outpatients (ages 18 to 66) meeting DSM-III or DSM-III-R criteria for major depressive disorder (MDD) (Studies 1 and 2). Study 1, a 6-week trial in which patients received fixed citalopram doses of 10 mg, 20 mg, 40 mg, and 60 mg daily, showed that citalopram 40 daily and 60 mg daily (1.5 times the maximum recommended daily dosage) was effective as measured by the Hamilton Depression Rating Scale (HAMD) total score, the primary efficacy endpoint. The HAMD-17 is a 17-item, clinician-rated scale used to assess severity of depressive symptoms. Scores on the HAMD-17 range from 0 to 52, with higher scores indicating more severe depression. This study showed no clear effect of the 10 mg and 20 mg daily doses, and the 60 mg daily dose was not more effective than the 40 mg daily dose. Due to the risk of QTc prolongation and ventricular arrhythmias, the maximum recommended dosage of citalopram is 40 mg once daily. In study 2, a 4-week, placebo-controlled trial in patients with MDD, the initial dose was 20 mg daily, followed by titration to the maximum tolerated dose or a maximum dose of 80 mg daily (2 times the maximum recommended daily dosage). Patients treated with citalopram showed statistically significantly greater improvement than placebo patients on the HAMD total score, the primary efficacy endpoint. In three additional placebo-controlled trials in patients with MDD, the difference in response to treatment between patients receiving citalopram and patients receiving placebo was not statistically significant. In two long-term studies, patients with MDD who had responded to citalopram during an initial 6 or 8 weeks of acute treatment were randomized to continuation of citalopram or placebo. In one study, patients received fixed doses of citalopram 20 mg or 40 mg daily and in the second study, patients received flexible doses of citalopram 20 mg daily to 60 mg daily (1.5 times the maximum recommended daily dosage). In both studies, patients receiving continued citalopram treatment experienced statistically significantly lower relapse rates over the subsequent 6 months compared to those receiving placebo. In the fixed-dose study, the decreased rate of depression relapse was similar in patients receiving 20 mg or 40 mg daily of citalopram. Due to the risk of QTc prolongation and ventricular arrhythmias, the maximum recommended dosage of citalopram is 40 mg once daily. Analyses of the relationship between treatment outcome and age, gender, and race did not suggest any differential responsiveness on the basis of these patient characteristics.

8 USE IN SPECIFIC POPULATIONS • Pregnancy: SSRI use, particularly late in pregnancy, may increase the risk for persistent pulmonary hypertension and symptoms of poor adaptation (respiratory distress, temperature instability, feeding difficulties, hypotonia, tremor, irritability) in the neonate.
