Warning(s)

  • Suicidality
  • Antidepressants increased risk of suicidal thinking and behavior (suicidality) compared with placebo in children, adolescents, and young adults (18–24 years of age) with major depressive disorder and other psychiatric disorders; balance this risk with clinical need.1 12 14 Vilazodone is not approved for use in pediatric patients.1 (See Pediatric Use under Cautions.)

  • In pooled data analyses, risk of suicidality was not increased in adults >24 years of age and apparently was reduced in adults ≥65 years of age with antidepressant therapy compared with placebo.1 12 14

  • Depression and certain other psychiatric disorders are themselves associated with an increased risk of suicide.1 12 14 15

  • Appropriately monitor and closely observe all patients who are started on vilazodone therapy for clinical worsening, suicidality, or unusual changes in behavior; involve family members and/or caregivers in this process.1 12 14 15 (See Worsening of Depression and Suicidality Risk under Cautions.)

REMS:

FDA approved a REMS for vilazodone to ensure that the benefits outweigh the risk. However, FDA later rescinded REMS requirements. See the FDA REMS page () or the ASHP REMS Resource Center ().

Vilazodone Hydrochloride Dosage and Administration

General

  • Allow at least 2 weeks to elapse between discontinuance of an MAO inhibitor and initiation of vilazodone and vice versa.1 (See Contraindications and Serotonin Syndrome or Neuroleptic Malignant Syndrome [NMS]-like Reactions under Cautionsand also see Specific Drugs under Interactions.)

  • Monitor for possible worsening of depression, suicidality, or unusual changes in behavior, especially at the beginning of therapy or during periods of dosage adjustments.1 12 14 15 (See Worsening of Depression and Suicidality Risk under Cautions.)

  • Avoid abrupt discontinuance.1 5 Taper dosage gradually and monitor for withdrawal symptoms.1 5 If intolerable symptoms occur following dosage reduction or discontinuance, consider reinstituting previously prescribed dosage, then resume more gradual dosage reductions.1 (See Withdrawal of Therapy under Cautions.)

Administration

Oral Administration

Administer immediate-release tablets orally once daily with food.1 Taking the drug without food may result in inadequate drug concentrations and reduced efficacy.1 (See Food under Pharmacokinetics.)

Dosage

Available as vilazodone hydrochloride; dosage expressed in terms of the salt.1

Adults

Major Depressive Disorder
Oral

Titrate up to recommended target dosage of 40 mg once daily to reduce risk of adverse effects (particularly GI effects).1 29 30 Manufacturer recommends 10 mg once daily initially for 7 days, followed by 20 mg once daily for an additional 7 days, and 40 mg once daily thereafter.1 29 30 May use the Viibryd patient starter kit for initial 1-month titration period.1

If used with a potent CYP3A4 inhibitor, dosage adjustment required; dosage adjustment also may be required if used with a moderate CYP3A4 inhibitor.1 30 (See Interactions.)

Optimum duration not established; may require several months or longer of sustained antidepressant therapy.1 5 Although manufacturer states that long-term efficacy (i.e., >8 weeks) not studied,1 long-term therapy at a dosage of 40 mg once daily was effective and well tolerated in a 52-week, open-label trial.4 Periodically reassess need for continued therapy and appropriateness of dosage.1

Special Populations

Hepatic Impairment

No dosage adjustment required in patients with mild or moderate hepatic impairment; not studied in patients with severe hepatic impairment.1 8

Renal Impairment

No dosage adjustment required in patients with mild, moderate, or severe renal impairment.1 (See Renal Impairment under Cautions.)

Geriatric Patients

Dosage adjustment not necessary.1

Gender

Dosage adjustment based on gender not necessary.1

Cautions for Vilazodone Hydrochloride

Contraindications

  • Concurrent or recent (i.e., within 2 weeks) therapy with an MAO inhibitor.1 Allow at least 2 weeks to elapse between discontinuance of vilazodone and initiation of MAO inhibitor therapy and vice versa.1 (See Serotonin Syndrome or Neuroleptic Malignant Syndrome [NMS]-like Reactions under Cautions and also see Specific Drugs under Interactions.)

Warnings/Precautions

Warnings

Worsening of Depression and Suicidality Risk

Possible worsening of depression and/or emergence of suicidal ideation and behavior (suicidality) or unusual changes in behavior in both adult and pediatric patients with major depressive disorder, whether or not they are taking antidepressants; may persist until clinically important remission occurs.1 12 14 15 28 (See Boxed Warning and also see Pediatric Use under Cautions.) However, suicide is a known risk of depression and certain other psychiatric disorders, and these disorders themselves are the strongest predictors of suicide.1 12 14 15

Appropriately monitor and closely observe patients receiving vilazodone for any reason, particularly during initiation of therapy (i.e., the first few months) and during periods of dosage adjustments.1 12 14 15

Anxiety, agitation, panic attacks, insomnia, irritability, hostility, aggressiveness, impulsivity, akathisia, hypomania, and/or mania may be precursors to emerging suicidality.1 14 15 Consider changing or discontinuing therapy in patients whose depression is persistently worse or in those with emerging suicidality or symptoms that might be precursors to worsening depression or suicidality, particularly if severe, abrupt in onset, or not part of the patient’s presenting symptoms.1 14 If decision is made to discontinue drug therapy, taper vilazodone dosage as rapidly as is feasible but consider risks of abrupt discontinuance.1 14 (See Withdrawal of Therapy under Cautions.)

Prescribe in smallest quantity consistent with good patient management to reduce risk of overdosage.1 14

Other Warnings and Precautions

Serotonin Syndrome or Neuroleptic Malignant Syndrome (NMS)-like Reactions

Potentially life-threatening serotonin syndrome or neuroleptic malignant syndrome (NMS)-like reactions reported during concurrent therapy with SSRIs or SNRIs and other serotonergic drugs (e.g., 5-HT1 receptor agonists [triptans]), drugs that impair serotonin metabolism (e.g., MAO inhibitors), or antipsychotics or other dopamine antagonists.1 18 31 (See Contraindications under Cautions and also see Interactions.)

Symptoms of serotonin syndrome may include mental status changes (e.g., agitation, hallucinations, coma), autonomic instability (e.g., tachycardia, labile BP, hyperthermia), neuromuscular aberrations (e.g., hyperreflexia, incoordination), and/or GI symptoms (e.g., nausea, vomiting, diarrhea).1 18 31

Severe serotonin syndrome may resemble NMS, which is characterized by hyperthermia, muscle rigidity, autonomic instability with possible rapid fluctuation of vital signs, and mental status changes.1 31

Monitor patients receiving vilazodone for the development of serotonin syndrome or NMS-like signs and symptoms.1 If serotonin syndrome or NMS signs and symptoms occur, discontinue vilazodone and any concurrently administered serotonergic or antidopaminergic agents, including antipsychotic agents, and initiate supportive and symptomatic treatment.1

Seizures

Vilazodone has not been studied in patients with seizure disorders; use with caution in patients with a history of seizure disorder.1

Abnormal Bleeding

Possible increased risk of bleeding with drugs that interfere with serotonin reuptake, including vilazodone; events ranged from ecchymoses, hematomas, epistaxis, and petechiae to life-threatening hemorrhages.1 21 Concurrent use of aspirin, NSAIAs, warfarin, and other anticoagulants may increase risk.1 (See Drugs Affecting Hemostasis and Specific Drugs under Interactions and also see Advice to Patients.)

Activation of Mania/Hypomania

Possible activation of mania and hypomania; use with caution in patients with personal or family history of bipolar disorder, mania, or hypomania.1

Withdrawal of Therapy

Withdrawal effects (e.g., dysphoric mood, irritability, agitation, dizziness, sensory disturbances [e.g., paresthesias, such as electric shock sensations], anxiety, confusion, headache, lethargy, emotional lability, insomnia, hypomania, tinnitus, seizures) reported following discontinuance of serotonergic antidepressants, particularly when discontinuance was abrupt.1 5 6 7 Events generally self-limiting, but serious cases reported.1 5 6 7

Taper dosage gradually; monitor patients for withdrawal symptoms when discontinuing therapy.1 If intolerable symptoms occur following dosage reduction or discontinuance, consider reinstituting previously prescribed dosage then resume more gradual dosage reductions.1

Hyponatremia/SIADH

Although not reported with vilazodone therapy, treatment with SSRIs and SNRIs may cause hyponatremia; in many cases, SIADH is apparent cause.1 Increased risk in patients who are volume-depleted, elderly, or taking diuretics.1 Initiate appropriate medical intervention and consider drug discontinuance in patients with symptomatic hyponatremia.1

Specific Populations

Pregnancy

Category C.1

Possible complications, sometimes severe and requiring prolonged hospitalization, respiratory support, enteral nutrition, and other forms of supportive care in neonates exposed to serotonergic antidepressants (e.g., SSRIs, SNRIs) late in the third trimester; may arise immediately upon delivery.1 22 23 24 25 26 27

Conflicting findings from available studies evaluating possible risk of persistent pulmonary hypertension of the newborn (PPHN) following in utero exposure to SSRIs; currently unclear whether SSRI use during pregnancy can cause PPHN.32 33 34

Consult joint APA and ACOG guidelines (at ) for additional information on management of depression in women prior to conception and during pregnancy, including treatment algorithms.35

Effect on labor and delivery unknown.1

Lactation

Distributed into milk in animals; not known whether distributed into human milk.1 Consider breastfeeding only if potential benefit outweighs potential risk to child.1

Pediatric Use

Safety and efficacy not established in pediatric patients; not recommended for use in such patients.1

FDA warns that a greater risk of suicidal thinking or behavior (suicidality) occurred during the first few months of antidepressant treatment compared with placebo in children and adolescents with major depressive disorder, obsessive-compulsive disorder (OCD), or other psychiatric disorders based on pooled analyses of 24 short-term, placebo-controlled trials of 9 antidepressant drugs (SSRIs and others).1 14 However, a more recent meta-analysis of 27 placebo-controlled trials of 9 antidepressants (SSRIs and others) in patients <19 years of age with major depressive disorder, OCD, or non-OCD anxiety disorders suggests that the benefits of antidepressant therapy in treating these conditions may outweigh the risks of suicidal behavior or suicidal ideation.28 No suicides occurred in these pediatric trials.1 14 28

Carefully consider these findings when assessing potential benefits and risks of vilazodone in a child or adolescent for any clinical use.1 14 15 28 (See Suicidality in the Boxed Warning and also see Worsening of Depression and Suicidality Risk under Cautions.)

Geriatric Use

No substantial differences in pharmacokinetics relative to younger adults, but increased sensitivity in some geriatric individuals cannot be ruled out.1 (See Geriatric Patients under Dosage and Administration.)

Clinically important hyponatremia reported with serotonergic antidepressants (e.g., SSRIs, SNRIs) in geriatric patients.1 (See Hyponatremia/SIADH under Cautions.)

In pooled data analyses, a reduced risk of suicidality was observed in adults ≥65 years of age with antidepressant therapy compared with placebo.1 12 14 (See Suicidality in the Boxed Warning and also see Worsening of Depression and Suicidality Risk under Cautions.)

Hepatic Impairment

No dosage adjustment required in patients with mild or moderate hepatic impairment;1 8 not studied in patients with severe hepatic impairment.1

Renal Impairment

No dosage adjustment required in patients with mild, moderate, or severe renal impairment.1

Removal by dialysis not studied; however, vilazodone's large volume of distribution suggests that dialysis will not substantially reduce plasma concentrations of the drug.1

Common Adverse Effects

Diarrhea,1 2 3 4 nausea,1 2 3 4 vomiting,1 insomnia.1

Absorption is decreased by about 25% if vomiting occurs within 7 hours of ingestion.1

Food

Administration with food (a high-fat or light meal) increases oral bioavailability (peak plasma concentrations increased by about 147–160%; AUC increased by about 64–85%).1

Distribution

Extent

Widely distributed.1

Distributed into milk in rats; not known whether distributed into human milk.1

Plasma Protein Binding

Approximately 96–99%.1

Elimination

Metabolism

Extensively metabolized by CYP isoenzymes (primarily by CYP3A4; minor contributions from CYP2C19 and CYP2D6) and non-CYP (possibly by carboxylesterase) pathways.1

Elimination Route

Primarily by hepatic metabolism; only 1% recovered in urine and 2% recovered in feces as unchanged vilazodone.1

Half-life

Approximately 25 hours.1

Special Populations

Mild or moderate hepatic impairment does not affect apparent clearance.1

Mild or moderate renal impairment does not affect apparent clearance.1

Stability

Storage

Oral

Tablets

25°C (may be exposed to 15–30°C).1

Actions

  • Indolalkylamine antidepressant with dual mechanism of action; acts as a combined SSRI and 5-HT1A receptor partial agonist.1 2 3 4 9 19 29 30

  • Precise mechanism of antidepressant action not fully elucidated, but appears to be associated with potentiation of serotonergic activity in the CNS.1 Net result of vilazodone's SSRI activity and partial agonist activity at 5-HT1A receptors on serotonergic transmission and its role in the drug's antidepressant effect are unknown.1

  • Binds with high affinity to the serotonin reuptake site, but not to norepinephrine or dopamine reuptake sites.1

  • Potently and selectively inhibits reuptake of serotonin and binds selectively with high affinity to 5-HT1A receptors.1 9 10

Advice to Patients

  • Importance of providing copy of written patient information (medication guide) each time vilazodone is dispensed.1 12 14 15 Importance of advising patients to read the patient information before taking vilazodone and each time the prescription is refilled.1

  • Risk of suicidality; importance of patients, family, and caregivers being alert to and immediately reporting emergence of suicidality, worsening depression, or unusual changes in behavior, especially during the first few months of therapy or during periods of dosage adjustment.1 12 14 15 (See Worsening of Depression and Suicidality Risk under Cautions.)

  • Importance of advising patients to take vilazodone with food since the drug may be less effective when taken on an empty stomach.1 Importance of also informing patients that dosage of vilazodone should be titrated when initiating therapy.1

  • Importance of instructing patients not to take vilazodone with an MAO inhibitor or within 14 days of stopping the drug, and vice versa.1

  • Importance of informing patients of potential risk of serotonin syndrome and neuroleptic malignant syndrome (NMS)-like reactions, particularly with concurrent use of vilazodone and 5-HT1 receptor agonists (also called triptans), tramadol, tryptophan, other serotonergic agents, or antipsychotic agents.1 18 Importance of immediately contacting clinician if signs and symptoms of these syndromes develop (e.g., restlessness, hallucinations, loss of coordination, fast heart beat, increased body temperature, muscle stiffness, labile BP, diarrhea, coma, nausea, vomiting, confusion).1 18

  • Risk of seizures; caution patients about use of vilazodone if they have a history of a seizure disorder.1

  • Importance of patients being aware that withdrawal effects may occur when stopping vilazodone, especially with abrupt discontinuance of the drug.1

  • Importance of informing patients that if they receive diuretics, or are otherwise volume-depleted, or are elderly, that they may be at greater risk of developing hyponatremia during vilazodone therapy.1

  • Risk of cognitive and motor impairment; importance of exercising caution while operating hazardous machinery, including automobile driving, until patients are reasonably certain that vilazodone therapy does not adversely affect their ability to engage in such activities.1

  • Importance of avoiding alcohol during vilazodone therapy.1

  • Importance of advising patients to notify their clinician if they develop any allergic signs or symptoms during therapy (e.g., rash, hives, swelling, difficulty breathing).1

  • Importance of advising patients, their families, and caregivers to observe vilazodone-treated patients for signs of activation of mania/hypomania.1

  • Importance of informing clinicians of existing or contemplated concomitant therapy, including prescription and OTC drugs or herbal supplements, as well as any concomitant illnesses (e.g., bipolar disorder, seizure disorder) or personal or family history of suicidality or bipolar disorder.1

    Importance of advising patients about the risk of bleeding or bruising associated with concomitant use of vilazodone with aspirin or other NSAIAs, warfarin, or other drugs that affect coagulation.1

  • Importance of women informing clinicians if they are or plan to become pregnant or plan to breast-feed.1

  • Importance of advising patients that it usually takes several weeks of antidepressant therapy before they will start to feel better.1 Advise patients not to stop taking the drug if they do not feel the results right away.1

  • Importance of informing patients of other important precautionary information.1 (See Cautions.)
