INFORMATION FOR PATIENTS SECTION.

17 PATIENT COUNSELING INFORMATION. Advise the patient to read the FDA-approved patient labeling (Medication Guide). Suicidal Thoughts and Behaviors Advise patients and caregivers to look for the emergence of suicidality, especially early during treatment and when the dosage is adjusted up or down and instruct them to report such symptoms to the healthcare provider [see Boxed Warning and Warnings and Precautions (5.1)]. Dosage and Administration Instruct patients to take vilazodone hydrochloride tablets with food and to follow prescribed dosage instructions [see Dosage and Administration (2.1, 2.3, 2.4, 2.5)]. Serotonin Syndrome Caution patients about the risk of serotonin syndrome, particularly with the concomitant use of vilazodone hydrochloride tablets with other serotonergic drugs including triptans, tricyclic antidepressants, fentanyl, lithium, tramadol, tryptophan, buspirone, amphetamines, and St. Johns Wort, and with drugs that impair metabolism of serotonin (in particular, MAOIs, both those intended to treat psychiatric disorders and also others, such as linezolid). Patients should contact their health care provider or report to the emergency room if they experience signs or symptoms of serotonin syndrome [see Warnings and Precautions (5.2) and Drug Interactions (7)]. Increased Risk of Bleeding Inform patients about the concomitant use of vilazodone hydrochloride tablets with aspirin, NSAIDs, other antiplatelet drugs, warfarin, or other anticoagulants because the combined use of drugs that interfere with serotonin reuptake (e.g., vilazodone hydrochloride tablets) and these medications has been associated with an increased risk of bleeding. Advise them to inform their health care providers if they are taking or planning to take any prescription or over-the-counter medications that increase the risk of bleeding [see Warnings and Precautions (5.3)]. Activation of Mania/Hypomania Advise patients and their caregivers to observe for signs of activation of mania/hypomania and instruct them to report such symptoms to the healthcare provider [see Warnings and Precautions (5.4)]. Discontinuation Syndrome Advise patients not to abruptly discontinue vilazodone hydrochloride tablets and to discuss any tapering regimen with their healthcare provider. Adverse reactions can occur when vilazodone hydrochloride tablets are discontinued [see Warnings and Precautions (5.5)]. Seizures Caution patients about using vilazodone hydrochloride tablets if they have history of seizure disorder [see Warnings and Precautions (5.6)]. Sexual DysfunctionAdvise patients that use of vilazodone hydrochloride tablets may cause symptoms of sexual dysfunction in both male and female patients. Inform patients that they should discuss any changes in sexual function and potential management strategies with their healthcare provider [see Warnings and Precautions (5.9)].Allergic Reactions Advise patients to notify their healthcare provider if they develop an allergic reaction such as rash, hives, swelling, or difficulty breathing [see Adverse Reactions (6.2)]. Concomitant MedicationsAdvise patients to inform their health care providers if they are taking, or plan to take any prescription or over-the-counter medications since there is potential for interactions [see Drug Interactions (7.1)]. Pregnancy Advise pregnant women to notify their healthcare provider if they become pregnant or intend to become pregnant during treatment with vilazodone hydrochloride tablets [see Use in Specific Populations (8.1)]. Advise patients that vilazodone hydrochloride tablets use late in pregnancy may lead to an increased risk for neonatal complications requiring prolonged hospitalization, respiratory support, tube feeding, and/or persistent pulmonary hypertension of the newborn (PPHN) [see Use in Specific Populations (8.1)]. Advise patients that there is pregnancy exposure registry that monitors pregnancy outcomes in women exposed to vilazodone hydrochloride tablets during pregnancy [see Use in Specific Populations (8.1)].

Hyponatremia [see Warnings and Precautions (5.8)]. Sexual Dysfunction [see Warnings and Precautions (5.9)]. Most common adverse reactions (incidence >= 5% and at least twice the rate of placebo): diarrhea, nausea, vomiting, and insomnia (6). To report SUSPECTED ADVERSE REACTIONS, contact 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 and varying lengths of time, adverse reaction rates observed in the clinical trials of drug cannot be directly compared to rates in the clinical studies of another drug and may not reflect rates observed in practice. The most commonly observed adverse reactions in vilazodone hydrochloride tablets-treated with major depressive disorder MDD in placebo-controlled studies (incidence >= 5% and at least twice the rate of placebo) were diarrhea, nausea, vomiting, and insomnia. Patient Exposure The safety of vilazodone hydrochloride tablets were evaluated in 3,007 patients (18 to 70 years of age) diagnosed with MDD who participated in clinical studies, representing 676 patient-years of exposure. In an open-label 52 week study at 40 mg daily, 599 patients were exposed to vilazodone hydrochloride tablets for total of 348 patient-years. The adverse reaction information presented below was derived from studies of vilazodone hydrochloride tablets 20 mg and 40 mg daily in patients with MDD including: Four placebo-controlled to 10-week studies in 2,233 patients, including 1,266 vilazodone hydrochloride tablets -treated patients; and An open-label 52-week study of 599 vilazodone hydrochloride tablets -treated patients.These studies included titration period of 10 mg daily for days, followed by 20 mg daily for days or to 40 mg daily over weeks. In these clinical trials, vilazodone hydrochloride tablets were administered with food.Adverse reactions reported as reasons for discontinuation of treatmentIn these studies, 7.3% of the vilazodone hydrochloride tablets-treated patients discontinued treatment due to an adverse reaction, compared with 3.5% of placebo-treated patients. The most common adverse reaction leading to discontinuation in at least 1% of the vilazodone hydrochloride tablets-treated patients in the placebo-controlled studies was nausea (1.4%).Common adverse reactions in placebo-controlled MDD studiesTable shows the incidence of common adverse reactions occurring in >= 2% of vilazodone hydrochloride tablets-treated patients and greater than the rate of placebo-treated patients in MDD Studies. There were no dose-related adverse reactions between 20 mg and 40 mg reported.Table 2: Common Adverse Reactions Occurring in >=2% of Vilazodone Hydrochloride Tablets-Treated Patients and Greater than the Rate of Placebo-Treated PatientsSystem Organ Class Preferred TermPlaceboN=967Vilazodone Hydrochloride Tablets 20 mg/day N=288Vilazodone Hydrochloride Tablets 40 mg/day N=978Gastrointestinal disorders Diarrhea 10% 26% 29% Nausea 7% 22% 24% Dry mouth 5% 8% 7% Vomiting 2% 4% 5% Abdominal pain1 3% 7% 4% Dyspepsia 2% 2% 3% Flatulence 1% 3% 3% Gastroenteritis 1% 1% 2% Abdominal distension 1% 2% 1% Nervous system disorders Headache2 14% 15% 14% Dizziness 5% 6% 8% Somnolence 2% 4% 5% Paresthesia 1% 1% 2% Psychiatric disorders Insomnia 2% 7% 6% Abnormal dreams 2% 2% 3% Restlessness3 1% 2% 3% General disorders Fatigue 3% 4% 3% Cardiac disorders Palpitations <1% 1% 2% Metabolism and nutrition disorders Increased appetite 1% 1% 3% Musculoskeletal and connective tissue disorders Arthralgia 1% 2% 1% Investigations Increased weight 1% 1% 2% 1Includes abdominal discomfort, abdominal pain upper, and abdominal pain. 2Includes headache and tension headache 3Includes restlessness, akathisia, and restless legs syndrome Sexual adverse reactions are presented in Table 3Sexual adverse reactionsTable displays the most common sexual adverse reactions in the placebo-controlled MDD studies.

Reactions are categorized by body system according to the following definitions: frequent adverse reactions are those occurring in at least 1/100 patients; infrequent adverse reactions are those occurring in 1/100 to 1/1000 patients; rare reactions are those occurring in fewer than 1/1000 patients: Cardiac disorders: infrequent: ventricular extrasystoles Eye disorders: infrequent: dry eye, vision blurred, rare: cataracts Nervous System: frequent: sedation, tremor; infrequent: migraine Psychiatric disorders: infrequent: panic attackSkin and subcutaneous tissue disorders: infrequent: hyperhidrosis, night sweats. 6.2 Postmarketing Experience. The following adverse reactions have been identified during post-approval use of vilazodone hydrochloride tablets. Because these reactions are reported voluntarily from population of uncertain size, it is not always possible to estimate their frequency or establish causal relationship to drug exposure. Reports of adverse reactions temporally associated with vilazodone hydrochloride tablets that have been received since market introduction and that are not listed above include the following: General Disorders and Administration Site Conditions: irritability Nervous System Disorders: sleep paralysisPsychiatric Disorders: hallucinations, suicide attempt, suicidal ideationSkin and subcutaneous tissue disorders: rash, generalized rash, urticaria, drug eruptionGastrointestinal System: acute pancreatitis.

CLINICAL PHARMACOLOGY SECTION.

12 CLINICAL PHARMACOLOGY. 12.1 Mechanism of Action. The mechanism of action of vilazodone in the treatment of major depressive disorder is not fully understood, but is thought to be related to its enhancement of serotonergic activity in the CNS through selective inhibition of serotonin reuptake. Vilazodone is also partial agonist at serotonergic 5-HT1A receptors; however, the net result of this action on serotonergic transmission and its role in vilazodones antidepressant effect are unknown.. 12.2 Pharmacodynamics. Vilazodone binds with high affinity to the serotonin reuptake site (Ki= 0.1 nM), but not to the norepinephrine (Ki=56 nM) or dopamine (Ki=37 nM) reuptake sites. Vilazodone potently and selectively inhibits reuptake of serotonin (IC50= 1.6 nM). Vilazodone also binds selectively with high affinity to 5-HT1A receptors (IC50=2.1 nM) and is 5-HT1A receptor partial agonist. Cardiac ElectrophysiologyTreatment with vilazodone hydrochloride tablets did not prolong the QTc interval. The effect of vilazodone hydrochloride tablets [20, 40, 60, and 80 mg (2 times the recommended dosage)] on the QTc interval was evaluated in randomized, placebo-, and active-controlled (moxifloxacin 400 mg), parallel-group, thorough QTc study in 157 healthy subjects. The study demonstrated an ability to detect small effects. The upper bound of the 90% confidence interval for the largest placebo-adjusted, baseline-corrected QTc interval was below 10 msec, based on the individual correction method (QTcI). Thus, at doses of times the recommended dosage, vilazodone hydrochloride tablets did not prolong the QTc interval to clinically relevant extent. 12.3 Pharmacokinetics. Vilazodone activity is due primarily to the parent drug. The pharmacokinetics of vilazodone (5 mg to 80 mg) are dose-proportional. Accumulation of vilazodone after administration of single vilazodone hydrochloride tablet doses did not vary with dose, and steady-state was achieved in about days. Elimination of vilazodone is primarily by hepatic metabolism with terminal half-life of approximately 25 hours. At steady-state, after daily dosing of vilazodone hydrochloride tablets 40 mg under fed conditions, the mean Cmax value is 156 ng/mL, and the mean AUC (0-24 hours) value is 1645 ng.h/mL. Absorption Vilazodone concentrations peak at median of to hours (Tmax) after vilazodone hydrochloride tablets administration and decline with terminal half-life of approximately 25 hours. The absolute bioavailability of vilazodone is 72% with food. Vilazodone AUC and Cmax in the fasted state can be decreased by approximately 50% and 60%, respectively, compared to the fed state. Administration without food can result in inadequate drug concentrations and may reduce effectiveness. Coadministration of vilazodone hydrochloride tablets with ethanol or with proton pump inhibitor (pantoprazole) did not affect the rate or extent of vilazodone absorption. In addition, neither the Tmax nor terminal elimination rate of vilazodone was altered by coadministration with either pantoprazole or ethanol. Absorption is decreased by approximately 25% if vomiting occurs within hours of ingestion; no replacement dose is needed. Distribution Vilazodone is widely distributed and approximately 96 to 99% protein-bound. Administration of vilazodone hydrochloride tablets to patient taking another drug that is highly protein bound may cause increased free concentrations of the other drug, because vilazodone is highly bound to plasma protein. The interaction between vilazodone and other highly protein-bound drugs has not been evaluated. Metabolism and Elimination Vilazodone hydrochloride tablet is extensively metabolized through CYP and non-CYP pathways (possibly by carboxylesterase), with only 1% of the dose recovered in the urine and 2% of the dose recovered in the feces as unchanged vilazodone. CYP3A4 is primarily responsible for its metabolism among CYP pathways, with minor contributions from CYP2C19 and CYP2D6. Drug Interaction Studies Figure below includes the impact of other drugs on the pharmacokinetics of vilazodone [see Drug Interactions (7)]. In vitro studies indicate that vilazodone is unlikely to inhibit or induce the metabolism of substrates for CYP1A1, 1A2, 2A6, 2B6, 2C9, 2C19, 2D6, 2E1, 3A4 or 3A5, except for CYP2C8. The effect of vilazodone on CYP2C8 activity has not been tested in vivo. Figure below includes the impact of vilazadone on the pharmacokinetics of other drugs in vivo. Studies in Specific Populations: The presence of mild to severe renal impairment or mild to severe hepatic impairment did not affect the apparent clearance of vilazodone (see Figure 3). There were no pharmacokinetic differences of vilazodone in geriatric patients compared to younger patients, or between males and females (see Figure 3).

CLINICAL STUDIES SECTION.

14 CLINICAL STUDIES. The efficacy of vilazodone hydrochloride tablets as treatment for major depressive disorder was demonstrated in four multicenter, randomized, double-blind, placebo-controlled studies in adult (18 to 70 years of age) outpatients who met the Diagnostic and Statistical Manual of Mental Disorders (DSM-IV-TR) criteria for MDD. Three 8-week studies evaluated the efficacy of vilazodone hydrochloride tablets 40 mg (Studies to 3) and one 10-week study (Study 4) evaluated the efficacy of vilazodone hydrochloride tablets 20 mg and 40 mg (see Table 5). In these studies, patients were randomized to either 20 mg or 40 mg, or placebo once daily with food. Patients were either titrated over 1week to dose of 20 mg daily or over weeks to dose of 40 mg once daily of vilazodone hydrochloride tablets with food. Vilazodone hydrochloride tablet was superior to placebo in the improvement of depressive symptoms as measured by the mean change from baseline to endpoint visit in the Montgomery-Asberg Depression Rating Scale (MADRS) total score for both doses. The MADRS is ten-text, clinician-rated scale used to assess severity of depressive symptoms. Scores on the MADRS range from to 60, with higher scores indicating more severe depression. Clinical Global Impression Severity (CGI-S) was evaluated in Studies and 4. Vilazodone hydrochloride tablets 20 mg and 40 mg demonstrated superiority over placebo as measured by improvement in CGI-S score.

DOSAGE & ADMINISTRATION SECTION.

2 DOSAGE AND ADMINISTRATION. Recommended target dosage: 20 mg to 40 mg once daily with food (2.1, 12.3). To titrate: start with initial dosage of 10 mg once daily for days, followed by 20 mg once daily. The dose may be increased up to 40 mg once daily after minimum of days between dosage increases (2.1). Prior to initiating vilazodone hydrochloride tablets, screen for bipolar disorder (2.2, 5.4). When discontinuing vilazodone hydrochloride tablets, reduce the dosage gradually (2.4, 5.5).. 2.1 Dosage for Treatment of Major Depressive Disorder. The recommended target dosage for vilazodone hydrochloride tablet is 20 mg to 40 mg orally once daily with food [see Clinical Pharmacology (12.3), Clinical Studies (14)]. To achieve the target dosage, titrate vilazodone hydrochloride tablet as follows:o Start with an initial dosage of 10 mg once daily with food for days, Then increase to 20 mg once daily with food. The dose may be increased up to 40 mg once daily with food after minimum of days between dosage increases.If dose is missed, it should be taken as soon as the patient remembers. If it is almost time for the next dose, the patient should skip the missed dose and take the next dose at the regular time. Two doses should not be taken at the same time. 2.2 Screen for Bipolar Disorder Prior to Starting Vilazodone Hydrochloride Tablets. Prior to initiating treatment with vilazodone hydrochloride tablet or another antidepressant, screen patients for personal or family history of bipolar disorder, mania, or hypomania [see Warnings and Precautions (5.4)]. 2.3 Switching to or from Monoamine Oxidase Inhibitor Antidepressant. At least 14 days must elapse between discontinuation of monoamine oxidase inhibitor (MAOI) antidepressant and initiation of vilazodone hydrochloride tablet. In addition, at least 14 days must elapse after stopping vilazodone hydrochloride tablet before starting an MAOI antidepressant [see Contraindications (4), Warnings and Precautions (5.2)]. 2.4 Dosage Adjustments with CYP3A4 Inhibitors or Inducers. Patients receiving concomitant CYP3A4 inhibitors: During concomitant use of strong CYP3A4 inhibitor (e.g., itraconazole, clarithromycin, voriconazole), the vilazodone hydrochloride tablet dose should not exceed 20 mg once daily. The original vilazodone hydrochloride tablet dose level, can be resumed when the CYP3A4 inhibitor is discontinued [see Drug Interactions (7)]. Patients receiving concomitant CYP3A4 inducers: Based on clinical response, consider increasing the dosage of vilazodone hydrochloride tablets by 2-fold, up to maximum 80 mg once daily, over to weeks in patients taking strong CYP3A4 inducers (e.g., carbamazepine, phenytoin, rifampin) for greater than 14 days. If CYP3A4 inducers are discontinued, gradually reduce the vilazodone hydrochloride tablet dosage to its original level over to weeks [see Drug Interactions (7)].. 2.5 Discontinuing Treatment with Vilazodone Hydrochloride Tablets. Adverse reactions may occur upon discontinuation of vilazodone hydrochloride tablet [see Warnings and Precautions (5.5)]. gradual reduction in dosage rather than abrupt cessation is recommended whenever possible. Vilazodone hydrochloride tablet should be down tapered from the 40 mg once daily dose to 20 mg once daily for days, followed by 10 mg once daily for days. Patients taking vilazodone hydrochloride tablet 20 mg once daily should be tapered to 10 mg once daily for days.

DRUG INTERACTIONS SECTION.

7 DRUG INTERACTIONS. oCYP3A4 Inhibitors: The vilazodone hydrochloride tablet dose should not exceed 20 mg once daily when co-administered with strong CYP3A4 inhibitors (2.4, 7). oCYP3A4 Inducers: Consider increasing vilazodone hydrochloride tablets dosage by 2-fold, up to 80 mg once-daily over to weeks when used concomitantly with strong CYP3A4 inducers for greater than 14 days (2.4, 7). 7.1 Drugs Having Clinically Important Interactions With Vilazodone Hydrochloride Tablets. Table 4: Clinically Important Drug Interactions with Vilazodone Hydrochloride TabletsConcomitant Drug Name or Drug Class Clinical Rationale Clinical Recommendation Monoamine Oxidase Inhibitors (MAOIs) The concomitant use of MAOIs and serotonergic drugs including vilazodone hydrochloride tablets increases the risk of serotonin syndrome. Vilazodone hydrochloride tablets are contraindicated in patients taking MAOIs, including MAOIs such as linezolid or intravenous methylene blue [see Contraindications (4), Dosage and Administration (2.3), and Warnings and Precautions (5.2)]. Other Serotonergic Drugs The concomitant use of serotonergic drugs including vilazodone hydrochloride tablets and other serotonergic drugs increases the risk of serotonin syndrome. Monitor patients for signs and symptoms of serotonin syndrome, particularly during vilazodone hydrochloride tablets initiation. If serotonin syndrome occurs, consider discontinuation of vilazodone hydrochloride tablets and/or concomitant serotonergic drugs [see Warnings and Precautions (5.2)]. Antiplatelet Agents and Anticoagulants Serotonin release by platelets plays an important role in hemostasis. The concurrent use of an antiplatelet agent or anticoagulant with vilazodone hydrochloride tablets may potentiate the risk of bleeding. Inform patients of the increased risk of bleeding with the concomitant use of vilazodone hydrochloride tablets and antiplatelet agents and anticoagulants. For patients taking warfarin, carefully monitor the international normalized ratio (INR) when initiating, titrating, or discontinuing vilazodone hydrochloride tablets [see Warnings and Precautions (5.3)]. Strong CYP3A4 Inhibitors (e.g., itraconazole, clarithromycin, voriconazole) The concomitant use of vilazodone hydrochloride tablets and strong CYP3A4 inhibitors increased the exposure of vilazodone compared to the use of vilazodone hydrochloride tablets alone [see Clinical Pharmacology (12.3)]. The vilazodone hydrochloride tablet dose should not exceed 20 mg once daily with the concomitant use of strong CYP3A4 inhibitor [see Dosage and Administration (2.4), Clinical Pharmacology (12.3)]. Strong CYP3A4Inducers (e.g.,carbamazepine,phenytoin,rifampin) The concomitant use of vilazodone hydrochloride tablets and strong CYP3A4 inducers decreased the exposure of vilazodone compared to the use of vilazodone hydrochloride tablets alone [see Clinical Pharmacology (12.3)]. Based on clinical response, consider increasing thedosage of vilazodone hydrochloride tablets, over to weeks in patientstaking strong CYP3A4 inducers for greater than 14 days [see Dosage and Administration (2.4), Clinical Pharmacology (12.3)]. Digoxin Digoxin is narrow therapeutic index drug. Concomitant use of vilazodone hydrochloride tablets increased digoxin concentrations [see Clinical Pharmacology (12.3)]. Measure serum digoxin concentrations before initiating concomitant use of vilazodone hydrochloride tablets. Continue monitoring and reduce digoxin dose as necessary. 7.2 Drugs Having No Clinically Important Interactions With Vilazodone Hydrochloride Tablets. Based on pharmacokinetic studies, no dosage adjustment is required for drugs that are substrates of CYP1A2, CYP2B6, CYP2C9, CYP2C19, CYP2D6, CYP3A4, and/or P-glycoprotein (except narrow therapeutic index drugs, e.g., digoxin), when vilazodone hydrochloride tablets are administered concomitantly [see Drug Interactions (7.1), Clinical Pharmacology (12.3)].

PHARMACOKINETICS SECTION.

12.3 Pharmacokinetics. Vilazodone activity is due primarily to the parent drug. The pharmacokinetics of vilazodone (5 mg to 80 mg) are dose-proportional. Accumulation of vilazodone after administration of single vilazodone hydrochloride tablet doses did not vary with dose, and steady-state was achieved in about days. Elimination of vilazodone is primarily by hepatic metabolism with terminal half-life of approximately 25 hours. At steady-state, after daily dosing of vilazodone hydrochloride tablets 40 mg under fed conditions, the mean Cmax value is 156 ng/mL, and the mean AUC (0-24 hours) value is 1645 ng.h/mL. Absorption Vilazodone concentrations peak at median of to hours (Tmax) after vilazodone hydrochloride tablets administration and decline with terminal half-life of approximately 25 hours. The absolute bioavailability of vilazodone is 72% with food. Vilazodone AUC and Cmax in the fasted state can be decreased by approximately 50% and 60%, respectively, compared to the fed state. Administration without food can result in inadequate drug concentrations and may reduce effectiveness. Coadministration of vilazodone hydrochloride tablets with ethanol or with proton pump inhibitor (pantoprazole) did not affect the rate or extent of vilazodone absorption. In addition, neither the Tmax nor terminal elimination rate of vilazodone was altered by coadministration with either pantoprazole or ethanol. Absorption is decreased by approximately 25% if vomiting occurs within hours of ingestion; no replacement dose is needed. Distribution Vilazodone is widely distributed and approximately 96 to 99% protein-bound. Administration of vilazodone hydrochloride tablets to patient taking another drug that is highly protein bound may cause increased free concentrations of the other drug, because vilazodone is highly bound to plasma protein.

PREGNANCY SECTION.

8.1 Pregnancy. Pregnancy Exposure Registry There is pregnancy exposure registry that monitors pregnancy outcomes in women exposed to antidepressants during pregnancy. Healthcare providers are encouraged to register patients by calling the National Pregnancy Registry for Antidepressants at 1-844-405-6185 or visiting online at https://womensmentalhealth.org/clinical-and-research-programs/pregnancyregistry/antidepressants/. Risk Summary There are no adequate and well-controlled studies of vilazodone hydrochloride tablets in pregnant women. The background risk of major birth defects and miscarriage for the indicated population is unknown. However, the background risk in the U.S. general population of major birth defects is to 4% and of miscarriage is 15 to 20% of clinically recognized pregnancies. In animal reproduction studies, oral administration of vilazodone during the period of organogenesis at doses up to 48 and 17 times the maximum recommended human dose (MRHD) in rats and rabbits, respectively, resulted in decreased fetal body weight gain and delayed skeletal ossification but no teratogenic effects were observed. Decreased fetal body weight and delayed skeletal ossification were not observed at doses up to 10 and times the MRHD in rats and rabbits, respectively [see Data]. Clinical Considerations Disease-associated maternal and/or embryo/fetal risk prospective, longitudinal study followed 201 pregnant women with history of major depressive disorder who were euthymic and taking antidepressants at the beginning of pregnancy. The women who discontinued antidepressants during pregnancy were more likely to experience relapse of major depression than women who continued antidepressants. Consider the risks of untreated depression when discontinuing or changing treatment with antidepressant medication during pregnancy and postpartum. Fetal/Neonatal adverse reactions Exposure to SSRIs and SNRIs, including vilazodone hydrochloride tablets, in late pregnancy may lead to an increased risk for neonatal complications requiring prolonged hospitalization, respiratory support, and tube feeding, and/or persistent pulmonary hypertension of the newborn (PPHN). Monitor neonates who were exposed to vilazodone hydrochloride tablets in the third trimester of pregnancy for PPHN and drug discontinuation syndrome [see Data]. Data Human Data Third Trimester Exposure Neonates exposed to SSRIs or SNRIs late in the third trimester, have developed complications requiring prolonged hospitalization, respiratory support, and tube feeding. These findings are based on post-marketing reports. Such complications can arise immediately upon delivery. Reported clinical findings have included respiratory distress, cyanosis, apnea, seizures, temperature instability, feeding difficulty, vomiting, hypoglycemia, hypotonia, hypertonia, hyperreflexia, tremor, jitteriness, irritability, and constant crying. These features are consistent with either direct toxic effect of SSRIs and SNRIs or, possibly, drug discontinuation syndrome. In some cases, the clinical picture was consistent with serotonin syndrome [see Warnings and Precautions (5.2)]. Exposure during late pregnancy to SSRIs may have an increased risk for persistent pulmonary hypertension of the newborn (PPHN). PPHN occurs in to per 1,000 live births in the general population and is associated with substantial neonatal morbidity and mortality. In retrospective case-control study of 377 women whose infants were born with PPHN and 836 women whose infants were born healthy, the risk for developing PPHN was approximately six-fold higher for infants exposed to SSRIs after the 20th week of gestation compared to infants who had not been exposed to antidepressants during pregnancy. study of 831,324 infants born in Sweden in 1997 to 2005 found PPHN risk ratio of 2.4 (95% CI 1.2 to 4.3) associated with patient-reported maternal use of SSRIs in early pregnancy and PPHN risk ratio of 3.6 (95% CI 1.2 to 8.3) associated with combination of patient-reported maternal use of SSRIs in early pregnancy and an antenatal SSRI prescription in later pregnancy. Animal Data No teratogenic effects were observed when vilazodone was given to pregnant rats or rabbits during the period of organogenesis at oral doses up to 200 and 36 mg/kg/day, respectively. These doses are 48 and 17 times, in rats and rabbits, respectively, the maximum recommended human dose (MRHD) of 40 mg on mg/m2 basis. Fetal body weight gain was reduced, and skeletal ossification was delayed in both rats and rabbits at these doses; these effects were not observed at doses up to 10 times the MRHD in rats or times the MRHD in rabbits. When vilazodone was administered to pregnant rats at an oral dose of 30 times the MRHD during the period of organogenesis and throughout pregnancy and lactation, the number of live born pups was decreased. There was an increase in early postnatal pup mortality, and among surviving pups there was decreased body weight, delayed maturation, and decreased fertility in adulthood. There was some maternal toxicity at this dose. These effects were not seen at times the MRHD.

USE IN SPECIFIC POPULATIONS SECTION.

8 USE IN SPECIFIC POPULATIONS. Pregnancy: Third trimester use may increase risk for persistent pulmonary hypertension and withdrawal in the newborn (8.1).. 8.1 Pregnancy. Pregnancy Exposure Registry There is pregnancy exposure registry that monitors pregnancy outcomes in women exposed to antidepressants during pregnancy. Healthcare providers are encouraged to register patients by calling the National Pregnancy Registry for Antidepressants at 1-844-405-6185 or visiting online at https://womensmentalhealth.org/clinical-and-research-programs/pregnancyregistry/antidepressants/. Risk Summary There are no adequate and well-controlled studies of vilazodone hydrochloride tablets in pregnant women. The background risk of major birth defects and miscarriage for the indicated population is unknown. However, the background risk in the U.S. general population of major birth defects is to 4% and of miscarriage is 15 to 20% of clinically recognized pregnancies. In animal reproduction studies, oral administration of vilazodone during the period of organogenesis at doses up to 48 and 17 times the maximum recommended human dose (MRHD) in rats and rabbits, respectively, resulted in decreased fetal body weight gain and delayed skeletal ossification but no teratogenic effects were observed. Decreased fetal body weight and delayed skeletal ossification were not observed at doses up to 10 and times the MRHD in rats and rabbits, respectively [see Data]. Clinical Considerations Disease-associated maternal and/or embryo/fetal risk prospective, longitudinal study followed 201 pregnant women with history of major depressive disorder who were euthymic and taking antidepressants at the beginning of pregnancy. The women who discontinued antidepressants during pregnancy were more likely to experience relapse of major depression than women who continued antidepressants. Consider the risks of untreated depression when discontinuing or changing treatment with antidepressant medication during pregnancy and postpartum. Fetal/Neonatal adverse reactions Exposure to SSRIs and SNRIs, including vilazodone hydrochloride tablets, in late pregnancy may lead to an increased risk for neonatal complications requiring prolonged hospitalization, respiratory support, and tube feeding, and/or persistent pulmonary hypertension of the newborn (PPHN). Monitor neonates who were exposed to vilazodone hydrochloride tablets in the third trimester of pregnancy for PPHN and drug discontinuation syndrome [see Data]. Data Human Data Third Trimester Exposure Neonates exposed to SSRIs or SNRIs late in the third trimester, have developed complications requiring prolonged hospitalization, respiratory support, and tube feeding. These findings are based on post-marketing reports. Such complications can arise immediately upon delivery. Reported clinical findings have included respiratory distress, cyanosis, apnea, seizures, temperature instability, feeding difficulty, vomiting, hypoglycemia, hypotonia, hypertonia, hyperreflexia, tremor, jitteriness, irritability, and constant crying. These features are consistent with either direct toxic effect of SSRIs and SNRIs or, possibly, drug discontinuation syndrome. In some cases, the clinical picture was consistent with serotonin syndrome [see Warnings and Precautions (5.2)]. Exposure during late pregnancy to SSRIs may have an increased risk for persistent pulmonary hypertension of the newborn (PPHN). PPHN occurs in to per 1,000 live births in the general population and is associated with substantial neonatal morbidity and mortality. In retrospective case-control study of 377 women whose infants were born with PPHN and 836 women whose infants were born healthy, the risk for developing PPHN was approximately six-fold higher for infants exposed to SSRIs after the 20th week of gestation compared to infants who had not been exposed to antidepressants during pregnancy. study of 831,324 infants born in Sweden in 1997 to 2005 found PPHN risk ratio of 2.4 (95% CI 1.2 to 4.3) associated with patient-reported maternal use of SSRIs in early pregnancy and PPHN risk ratio of 3.6 (95% CI 1.2 to 8.3) associated with combination of patient-reported maternal use of SSRIs in early pregnancy and an antenatal SSRI prescription in later pregnancy. Animal Data No teratogenic effects were observed when vilazodone was given to pregnant rats or rabbits during the period of organogenesis at oral doses up to 200 and 36 mg/kg/day, respectively. These doses are 48 and 17 times, in rats and rabbits, respectively, the maximum recommended human dose (MRHD) of 40 mg on mg/m2 basis. Fetal body weight gain was reduced, and skeletal ossification was delayed in both rats and rabbits at these doses; these effects were not observed at doses up to 10 times the MRHD in rats or times the MRHD in rabbits. When vilazodone was administered to pregnant rats at an oral dose of 30 times the MRHD during the period of organogenesis and throughout pregnancy and lactation, the number of live born pups was decreased. There was an increase in early postnatal pup mortality, and among surviving pups there was decreased body weight, delayed maturation, and decreased fertility in adulthood. There was some maternal toxicity at this dose. These effects were not seen at times the MRHD.. 8.2 Lactation. Risk Summary There are no data on the presence of vilazodone in human milk, the effects of vilazodone on the breastfed infant, or the effects of the drug on milk production. However, vilazodone is excreted in rat milk [see Data]. The developmental and health benefits ofbreastfeeding should be considered along with the mothers clinical need for vilazodone hydrochloride tablets and any potential adverse effects on the breastfed child from vilazodone hydrochloride tablets or from the underlying maternal condition. Data Animal Data Administration of vilazodone to lactating rats at an oral dose of 30 times the maximum recommended human dose (MRHD), resulted in early postnatal pup mortality, and among surviving pups there was decreased body weight and delayed maturation. 8.4 Pediatric Use. The safety and effectiveness of vilazodone hydrochloride tablets have not been established in pediatric patients for the treatment of MDD. Antidepressants increased the risk of suicidal thoughts and behaviors in pediatric patients [see Boxed Warning, Warnings and Precautions (5.1), and Adverse Reactions (6.2)]. Juvenile Animal Toxicity Data In juvenile animal study, male and female rats were treated with vilazadone (10, 50, and 200 mg/kg/day) starting on postnatal day (PND) 21 through 90. delay in the age of attainment of vaginal patency (i.e., sexual maturation) was observed in females starting at 50 mg/kg/day with No Observed Adverse Effect Level (NOAEL) of 10 mg/kg/day. Adverse behavioral effects (lack of habituation in an acoustic startle test) were observed in males at 200 mg/kg and females starting at 50 mg/kg both during drug treatment and the recovery periods. The NOAEL for this finding was 50 mg/kg for males and 10 mg/kg for females. An 8% decrease in femur mineral density was observed in female rats at 200 mg/kg, compared to the control group. The NOAEL for this finding was 50 mg/kg. Pediatric information describing clinical study in which efficacy was not demonstrated is approved for Allergans Viibryd (vilazodone hydrochloride) tablets. However, due to Allergans marketing exclusivity rights, this drug product is not labeled with that information. 8.5 Geriatric Use. Based on pharmacokinetic study, no dosage adjustment of vilazodone hydrochloride tablets are recommended on the basis of age (see Figure 3). Results from pharmacokinetic study of single 20 mg vilazodone hydrochloride tablet dose in geriatric subjects (> 65 years-old) vs. younger subjects (24 to 55 years-old) demonstrated that the pharmacokinetics were generally similar between the two age groups [see Clinical Pharmacology (12.3)]. Clinical studies of vilazodone hydrochloride tablets did not include sufficient numbers of subjects aged 65 and over to determine whether they respond differently from younger subjects. Of the 3,007 patients in clinical studies with vilazodone hydrochloride tablets, 65 (2.2%) were 65 years of age or older, and 378 (12.6%) were 55 to 64 years of age. In general, dose selection for an elderly patient should be conservative, usually starting at the low end of the dosing range, reflecting the greater frequency of decreased hepatic, renal, or cardiac function, and of concomitant disease or other drug therapy. Serotonergic antidepressants have been associated with cases of clinically significant hyponatremia in elderly patients, who may be at greater risk for this adverse reaction [see Warnings and Precautions (5.8)]. No other differences in adverse reactions were observed between geriatric and younger patients.. 8.6 Use in Other Patient Populations. No dosage adjustment of vilazodone hydrochloride tablets are necessary on the basis of gender, renal function (mild to severe renal impairment, glomerular filtration rate: 15 to 90 mL/minute), or hepatic function (mild to severe hepatic impairment, Child-Pugh score: to 15 [see Clinical Pharmacology (12.3)].

WARNINGS AND PRECAUTIONS SECTION.

5 WARNINGS AND PRECAUTIONS. Serotonin Syndrome: Increased risk when co-administered with other serotonergic agents (e.g., SSRI, SNRI, triptans, amphetamines), but also when taken alone. If it occurs, discontinue vilazodone hydrochloride tablets and initiate supportive treatment (5.2). Increased Risk of Bleeding: Concomitant use of aspirin, nonsteroidal anti-inflammatory drugs (NSAIDs), other antiplatelet drugs, warfarin, and other anticoagulants may increase this risk (5.3). Activation of Mania/Hypomania: Screen patients for bipolar disorder (5.4). Seizures: Can occur with treatment. Use with caution in patients with seizure disorder (5.6). Angle Closure Glaucoma: Avoid use of antidepressants, including vilazodone hydrochloride tablets, in patients with untreated anatomically narrow angles (5.7). Sexual Dysfunction: Vilazodone hydrochloride tablets may cause symptoms of sexual dysfunction (5.9).. 5.1 Suicidal Thoughts and Behavior in Adolescents and Young Adults. In pooled analyses of placebo-controlled trials of antidepressant drugs (SSRIs and other antidepressant classes) that included approximately 77,000 adult patients, and over 4,500 pediatric patients, the incidence of suicidal thoughts and behaviors in antidepressant-treated patients age 24 years and younger was greater in antidepressant-treated patients than in placebo-treated patients. There was considerable variation in risk of suicidal thoughts and behaviors among drugs, but there was an increased risk identified in young patients for most drugs studied. There were differences in absolute risk of suicidal thoughts and behaviors across the different indications, with the highest incidence in patients with MDD. The drug-placebo differences in the number of cases of suicidal thoughts and behaviors per 1000 patients treated are provided in Table 1. Table 1: Risk Differences of the Number of Patients with Suicidal Thoughts or Behaviors in the Pooled Placebo-Controlled Trials of Antidepressants in Pediatric and Adult PatientsAge RangeDrug-Placebo Difference in Number of Patients with Suicidal Thoughts or Behaviors per 1000 Patients Treated Increases Compared to Placebo<18 14 additional patients 18 to 24 additional patients Decreases Compared to Placebo25 to 64 fewer patient >=65 fewer patients It is unknown whether the risk of suicidal thoughts and behaviors in children, adolescents, and young adults extends to longer-term use, i.e., beyond four months. However, there is substantial evidence from placebo-controlled maintenance studies in adults with MDD that antidepressants delay the recurrence of depression and that depression itself is risk factor for suicidal thoughts and behaviors.Monitor all antidepressant-treated patients for clinical worsening and emergence of suicidal thoughts and behaviors, especially during the initial few months of drug therapy and at times of dosage changes. Counsel family members or caregivers of patients to monitor for changes in behavior and to alert the healthcare provider. Consider changing the therapeutic regimen, including possibly discontinuing vilazodone hydrochloride tablets, in patients whose depression is persistently worse, or who are experiencing emergent suicidal thoughts or behaviors.. 5.2 Serotonin Syndrome. Serotonin and norepinephrine reuptake inhibitors (SNRIs) and selective serotonin reuptake inhibitor (SSRIs), including vilazodone hydrochloride tablets, can precipitate serotonin syndrome, potentially life-threatening condition. The risk is increased with concomitant use of other serotonergic drugs (including triptans, tricyclic antidepressants, fentanyl, lithium, tramadol, tryptophan, buspirone, amphetamines, and St. Johns Wort) and with drugs that impair metabolism of serotonin, i.e., MAOIs [see Contraindications (4) and Drug Interactions (7)].Serotonin syndrome can also occur when these drugs are used alone. Symptoms of serotonin syndrome were noted in 0.1% of MDD patients treated with vilazodone hydrochloride tablets in premarketing clinical trials. Serotonin syndrome signs and symptoms may include mental status changes (e.g., agitation, hallucinations, delirium, and coma), autonomic instability (e.g., tachycardia, labile blood pressure, dizziness, diaphoresis, flushing, hyperthermia), neuromuscular symptoms (e.g., tremor, rigidity, myoclonus, hyperreflexia, incoordination), seizures, and gastrointestinal symptoms (e.g., nausea, vomiting, diarrhea). The concomitant use of vilazodone hydrochloride tablets with MAOIs is contraindicated. In addition, do not initiate vilazodone hydrochloride tablets in patient being treated with MAOIs such as linezolid or intravenous methylene blue. No reports involved the administration of methylene blue by other routes (such as oral tablets or local tissue injection). If it is necessary to initiate treatment with an MAOI such as linezolid or intravenous methylene blue in patient taking vilazodone hydrochloride tablets, discontinue vilazodone hydrochloride tablets before initiating treatment with the MAOI [see Contraindications (4), Drug Interactions (7.1)]. Monitor all patients taking vilazodone hydrochloride tablets for the emergence of serotonin syndrome. Discontinue treatment with vilazodone hydrochloride tablets and any concomitant serotonergic agents immediately if the above symptoms occur, and initiate supportive symptomatic treatment. If concomitant use of vilazodone hydrochloride tablets with other serotonergic drugs is clinically warranted, inform patients of the increased risk for serotonin syndrome and monitor for symptoms.. 5.3 Increased Risk of Bleeding. Drugs that interfere with serotonin reuptake inhibition, including vilazodone hydrochloride tablets, increase the risk of bleeding events. Concomitant use of aspirin, nonsteroidal anti-inflammatory drugs (NSAIDS), other antiplatelet drugs, warfarin, and other anticoagulants may add to this risk. Case reports and epidemiological studies (case-control and cohort design) have demonstrated an association between use of drugs that interfere with serotonin reuptake and the occurrence of gastrointestinal bleeding. Bleeding events related to drugs that interfere with serotonin reuptake have ranged from ecchymosis, hematoma, epistaxis, and petechiae to life-threatening hemorrhages. Inform patients about the risk of bleeding associated with the concomitant use of vilazodone hydrochloride tablets and antiplatelet agents or anticoagulants. For patients taking warfarin, carefully monitor coagulation indices when initiating, titrating, or discontinuing vilazodone hydrochloride tablets. 5.4 Activation of Mania or Hypomania. In patients with bipolar disorder, treating depressive episode with vilazodone hydrochloride tablets or another antidepressant may precipitate mixed/manic episode. In controlled clinical trials, patients with bipolar disorder were excluded; however, symptoms of mania or hypomania were reported in 0.1% of undiagnosed patients treated with vilazodone hydrochloride tablets. Prior to initiating treatment with vilazodone hydrochloride tablets, screen patients for any personal or family history of bipolar disorder, mania, or hypomania [see Dosage and Administration (2.2)]. 5.5 Discontinuation Syndrome. Adverse reactions after discontinuation of serotonergic antidepressants, particularly after abrupt discontinuation, include: nausea, sweating, dysphoric mood, irritability, agitation, dizziness, sensory disturbances (e.g., paresthesia, such as electric shock sensations), tremor, anxiety, confusion, headache, lethargy, emotional lability, insomnia, hypomania, tinnitus, and seizures. gradual reduction in dosage rather than abrupt cessation is recommended whenever possible [see Dosage and Administration (2.5)].. 5.6 Seizures. Vilazodone hydrochloride tablets have not been systematically evaluated in patients with seizure disorder. Patients with history of seizures were excluded from clinical studies. Vilazodone hydrochloride tablets should be prescribed with caution in patients with seizure disorder.. 5.7 Angle-Closure Glaucoma. The pupillary dilation that occurs following use of many antidepressant drugs including vilazodone hydrochloride tablets may trigger an angle closure attack in patient with anatomically narrow angles who does not have patent iridectomy. Avoid use of antidepressants, including vilazodone hydrochloride tablets, in patients with untreated anatomically narrow angles.. 5.8 Hyponatremia. Hyponatremia may occur as result of treatment with SNRIs and SSRIs, including vilazodone hydrochloride tablets. Cases of serum sodium lower than 110 mmol/L have been reported. Signs and symptoms of hyponatremia include headache, difficulty concentrating, memory impairment, confusion, weakness, and unsteadiness, which may lead to falls. Signs and symptoms associated with more severe and/or acute cases have included hallucination, syncope, seizure, coma, respiratory arrest, and death. In many cases, this hyponatremia appears to be the result of the syndrome of inappropriate antidiuretic hormone secretion (SIADH). In patients with symptomatic hyponatremia, discontinue vilazodone hydrochloride tablets and institute appropriate medical intervention. Elderly patients, patients taking diuretics, and those who are volume-depleted may be at greater risk of developing hyponatremia with SSRIs and SNRIs [see Use in Specific Populations (8.5)].. 5.9 Sexual Dysfunction. Use of SSRIs, including vilazodone hydrochloride tablets, may cause symptoms of sexual dysfunction [see Adverse Reactions (6.1)]. In male patients, SSRI use may result in ejaculatory delay or failure, decreased libido, and erectile dysfunction. In female patients, SSRI use may result in decreased libido and delayed or absent orgasm. It is important for prescribers to inquire about sexual function prior to initiation of vilazodone hydrochloride tablets and to inquire specifically about changes in sexual function during treatment, because sexual function may not be spontaneously reported. When evaluating changes in sexual function, obtaining detailed history (including timing of symptom onset) is important because sexual symptoms may have other causes, including the underlying psychiatric disorder. Discuss potential management strategies to support patients in making informed decisions about treatment.
