Indicaciones
1 INDICATIONS AND USAGE Citalopram tablets are indicated for the treatment of major depressive disorder (MDD) in adults [see Clinical Studies (14) ] . Citalopram tablets are a selective serotonin reuptake inhibitor (SSRI) indicated for the treatment of major depressive disorder (MDD) in adults ( 1 ) .
Posología
2 DOSAGE AND ADMINISTRATION Administer once daily with or without food ( 2 ) . Initial dosage is 20 mg once daily; after one week may increase to maximum dosage of 40 mg once daily ( 2.1 ). Patients greater than 60 years of age, patients with hepatic impairment, and CYP2C19 poor metabolizers: maximum recommended dosage is 20 mg once daily ( 2.2 ). When discontinuing citalopram tablets, reduce dosage gradually ( 2.4 , 5.6 ). 2.1 Recommended Dosage Administer citalopram tablets once daily, with or without food, at an initial dosage of 20 mg once daily, with an increase to a maximum dosage of 40 mg once daily at an interval of no less than one week. Dosages above 40 mg once daily are not recommended due to the risk of QT prolongation [see Warnings and Precautions (5.2) ] . 2.2 Screen for Bipolar Disorder Prior to Starting Citalopram Tablets Prior to initiating treatment with citalopram tablets or another antidepressant, screen patients for a personal or family history of bipolar disorder, mania, or hypomania [See Warnings and Precautions (5.5) ]. 2.3 Recommended Dosage for Specific Populations The maximum recommended dosage of citalopram tablets for patients who are greater than 60 years of age, patients with hepatic impairment, and for CYP2C19 poor metabolizers is 20 mg once daily [see Warnings and Precautions (5.2) , Clinical Pharmacology (12.3) ]. 2.4 Dosage Modifications with Concomitant Use of CYP2C19 Inhibitors The maximum recommended dosage of citalopram tablets when used concomitantly with a CYP2C19 inhibitor is 20 mg once daily [see Warnings and Precautions (5.2) , Drug Interactions (7) ]. 2.5 Switching Patients to or from a Monoamine Oxidase Inhibitor Antidepressant At least 14 days must elapse between discontinuation of a monoamine oxidase inhibitor (MAOI) antidepressant and initiation of therapy with citalopram tablets. Conversely, at least 14 days must elapse after stopping citalopram tablets before starting an MAOI antidepressant [see Contraindications (4) and Warnings and Precautions (5.3) ] . 2.6 Discontinuing Treatment with Citalopram Tablets Adverse reactions may occur upon discontinuation of citalopram tablets [see Warnings and Precautions (5.6) ] . Gradually reduce the dosage rather than stopping citalopram tablets abruptly whenever possible.
Contraindicaciones
4 CONTRAINDICATIONS Citalopram tablets are contraindicated in patients: taking, or within 14 days of stopping, MAOIs (including MAOIs such as linezolid or intravenous methylene blue) because of an increased risk of serotonin syndrome [see Warnings and Precautions (5.3) , Drug Interactions (7) ] . taking pimozide because of risk of QT prolongation [see Drug Interactions (7) ] . with known hypersensitivity to citalopram or any of the inactive ingredients in citalopram tablets. Reactions have included angioedema and anaphylaxis [see Adverse Reactions (6.2) ]. Concomitant use of monoamine oxidase inhibitors (MAOIs) or use within 14 days of discontinuing a MAOI ( 4 ). Concomitant use of pimozide ( 4 ). Known hypersensitivity to citalopram or any of the inactive ingredients of citalopram ( 4 ).

8.1 Pregnancy Pregnancy Exposure Registry There is a pregnancy exposure registry that monitors pregnancy outcomes in women exposed to antidepressants during pregnancy. Healthcare providers are encouraged to advise patients to register by calling the National Pregnancy Registry for Antidepressants at 1-844-405-6185 or visiting online at https://womensmentalhealth.org/research/pregnancyregistry/antidepressants . Risk Summary Based on data from published observational studies, exposure to SSRIs, particularly in the month before delivery, has been associated with a less than 2-fold increase in the risk of postpartum hemorrhage [see Warnings and Precautions (5.4) and Clinical Considerations]. Available data from published epidemiologic studies and postmarketing reports with citalopram use in pregnancy have not established an increased risk of major birth defects or miscarriage. Published studies demonstrated that citalopram levels in both cord blood and amniotic fluid are similar to those observed in maternal serum. There are risks of persistent pulmonary hypertension of the newborn (PPHN) (see Data) and/or poor neonatal adaptation with exposure to selective serotonin reuptake inhibitors (SSRIs), including citalopram, during pregnancy . There also are risks associated with untreated depression in pregnancy (see Clinical Considerations) . In animal reproduction studies, citalopram caused adverse embryo/fetal effects at doses that caused maternal toxicity (see Data) . The estimated

6 ADVERSE REACTIONS The following adverse reactions are discussed in greater detail in other sections of the labeling: Hypersensitivity reactions [see Contraindications (4) ] Suicidal thoughts and behaviors in adolescents and young adults [see Warnings and Precautions (5.1) ] QT-prolongation and torsade de pointes [see Warnings and Precautions (5.2) ] Serotonin syndrome [see Warnings and Precautions (5.3) ] Increased risk of bleeding [see Warnings and Precautions (5.4) ] Activation of mania or hypomania [see Warnings and Precautions (5.5) ] Discontinuation syndrome [see Warnings and Precautions (5.6) ] Seizures [see Warnings and Precautions (5.7) ] Angle-closure glaucoma [see Warnings and Precautions (5.8) ] Hyponatremia [see Warnings and Precautions (5.9) ] Sexual Dysfunction [see Warnings and Precautions (5.10) ] Most common adverse reaction (incidence ≥ 5% and twice placebo) is ejaculation disorder (primarily ejaculation delay) ( 6.1 ) . To report SUSPECTED ADVERSE REACTIONS, contact Aurobindo Pharma USA, Inc. at 1-866-850-2876 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch. 6.1 Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical studies of another drug and may not reflect the rates observed in clinical practice. The safety for citalopram included citalopram exposures in patients and/or healthy subjects from 3 different groups of studies: 429 healthy subjects in clinical pharmacology/pharmacokinetic studies; 4,422 exposures from patients in controlled and uncontrolled clinical trials, corresponding to approximately 1,370 patient-exposure years. There were, in addition, over 19,000 exposures from mostly open-label, European postmarketing studies. The conditions and duration of treatment with citalopram varied greatly and included (in overlapping categories) open-label and double-blind studies, inpatient and outpatient studies, fixed-dose and dose-titration studies, and short-term and long-term exposure. Adverse Reactions Associated with Discontinuation of Treatment Among 1,063 patients with MDD who received citalopram at doses ranging from 10 mg to 80 mg once daily in placebocontrolled trials of up to 6 weeks duration, 16% discontinued treatment due to an adverse reaction, as compared to 8% of 446 patients receiving placebo. The adverse reactions associated with discontinuation (i.e., associated with discontinuation in at least 1% of citalopram-treated patients at a rate at least twice that of placebo) are shown in Table 2 . Table 2: Adverse Reactions Associated with Discontinuation of Citalopram Treatment in Short-Term, Placebo-Controlled MDD Trials * A patient can report more than one reason for discontinuation and be counted more than once in this table. Body System/Adverse Reaction Citalopram Placebo (N=1,063) % (N=446) % General Asthenia 1 <1 Gastrointestinal Disorders Nausea 4 0 Dry Mouth 1 <1 Vomiting 1 0 Central and Peripheral Nervous System Disorders Dizziness 2 <1 Psychiatric Disorders Insomnia 3 1 Somnolence 2 1 Agitation 1 <1 Table 3 enumerates the incidence of adverse reactions that occurred among 1,063 patients with MDD who received citalopram at doses ranging from 10 mg to 80 mg once daily in placebo-controlled trials of up to 6 weeks duration. The most common adverse reaction that occurred in citalopram-treated patients with an incidence of 5% or greater and at least twice the incidence in placebo patients was ejaculation disorder (primarily ejaculatory delay) in male patients (see Table 3 ). Table 3: Adverse Reactions (≥2% and Greater than Placebo) Among Citalopram-Treated Patients * *Adverse reactions reported by at least 2% of patients treated with citalopram are reported, except for the following adverse reactions which had an incidence on placebo ≥ citalopram: headache, asthenia, dizziness, constipation, palpitation, vision abnormal, sleep d
