Use: Labeled Indications

Major depressive disorder: Treatment of major depressive disorder (MDD).

Contraindications

Hypersensitivity (eg, angioedema) to vortioxetine or any component of the formulation; use of MAO inhibitors intended to treat psychiatric disorders (concurrently or within 21 days of discontinuing vortioxetine or within 14 days of discontinuing the MAO inhibitor); initiation of vortioxetine in a patient receiving linezolid or intravenous methylene blue.

Dosing: Adult

Major depressive disorder: Oral: Initial: 10 mg once daily; increase to 20 mg once daily as tolerated; consider 5 mg once daily for patients who do not tolerate higher doses. Maintenance: 5 to 20 mg once daily.

Dosage adjustment for CYP2D6 poor metabolizers: Maximum dose: 10 mg/day.

Dosage adjustment for concomitant therapy with strong CYP2D6 inhibitors: Reduce total daily dose by one half when a strong CYP2D6 inhibitor (eg, bupropion, fluoxetine, paroxetine, or quinidine) is coadministered. Increase dose to original level when the CYP2D6 inhibitor is discontinued.

Dosage adjustment for concomitant therapy with strong CYP inducers: Consider increasing the dose when a strong CYP inducer (eg, rifampin, carbamazepine, phenytoin) is coadministered for >14 days. Maximum dose should not exceed three times the original dose. Reduce the dose to the original level within 14 days of discontinuing the CYP inducer.

Discontinuation of therapy: When discontinuing antidepressant treatment that has lasted for >3 weeks, gradually taper the dose (eg, over 2 to 4 weeks) to minimize withdrawal symptoms and detect reemerging symptoms (APA 2010; WFSBP [Bauer 2015]). Reasons for a slower titration (eg, over 4 weeks) include use of a drug with a half-life <24 hours (eg, paroxetine, venlafaxine), prior history of antidepressant withdrawal symptoms, or high doses of antidepressants (APA 2010; Hirsch 2019). If intolerable withdrawal symptoms occur, resume the previously prescribed dose and/or decrease dose at a more gradual rate (Shelton 2001). Select patients (eg, those with a history of discontinuation syndrome) on long-term treatment (>6 months) may benefit from tapering over >3 months (WFSBP [Bauer 2015]). Evidence supporting ideal taper rates is limited (Shelton 2001; WFSBP [Bauer 2015]).

Vortioxetine doses of 15 mg once daily or more are recommended by the manufacturer to be decreased to 10 mg once daily for one week before full discontinuation to prevent withdrawal symptoms.

MAO inhibitor recommendations:

Switching to or from an MAO inhibitor intended to treat psychiatric disorders:

Allow 14 days to elapse between discontinuing an MAO inhibitor intended to treat psychiatric disorders and initiation of vortioxetine.

Allow 21 days to elapse between discontinuing vortioxetine and initiation of an MAO inhibitor intended to treat psychiatric disorders.

Dosing: Geriatric

Major depressive disorder:

US labeling: Refer to adult dosing.

Canadian labeling: Oral: Initial: 5 mg once daily; may increase to 10 mg once daily as tolerated. Use caution with doses >10 mg daily (maximum: 20 mg/day).

Warnings/Precautions

Major psychiatric warnings:

• Suicidal thinking/behavior: [US Boxed Warning]: Antidepressants increase the risk of suicidal thinking and behavior in children, adolescents, and young adults (18 to 24 years) with major depressive disorder (MDD) and other psychiatric disorders; consider risk prior to prescribing. Short-term studies did not show an increased risk in patients >24 years and showed a decreased risk in patients ≥65 years. Closely monitor patients for clinical worsening, suicidality, or unusual changes in behavior, particularly during the initial 1 to 2 months of therapy or during periods of dosage adjustments (increases or decreases); the patient’s family or caregiver should be instructed to closely observe the patient and communicate condition with health care provider. A medication guide concerning the use of antidepressants should be dispensed with each prescription. Vortioxetine is not approved for use in children.

The possibility of a suicide attempt is inherent in major depression and may persist until remission occurs. Worsening depression and severe abrupt suicidality that are not part of the presenting symptoms may require discontinuation or modification of drug therapy. Use caution in high-risk patients during initiation of therapy.

Prescriptions should be written for the smallest quantity consistent with good patient care. The patient's family or caregiver should be alerted to monitor patients for the emergence of suicidality and associated behaviors such as anxiety, agitation, panic attacks, insomnia, irritability, hostility, aggressiveness, impulsivity, akathisia, hypomania, and mania; patients should be instructed to notify their healthcare provider if any of these symptoms or worsening depression occurs.

Concerns related to adverse effects:

• Bleeding risk: May impair platelet aggregation resulting in increased risk of bleeding events, particularly if used concomitantly with aspirin, NSAIDs, warfarin or other anticoagulants. Bleeding related to antidepressant use has been reported to range from relatively minor bruising and epistaxis to life-threatening hemorrhage.

• CNS depression: May cause CNS depression, which may impair physical or mental abilities; patients must be cautioned about performing tasks that require mental alertness (eg, operating machinery or driving).

• Fractures: Bone fractures have been associated with antidepressant treatment. Consider the possibility of a fragility fracture if an antidepressant-treated patient presents with unexplained bone pain, point tenderness, swelling, or bruising (Rabenda, 2013; Rizzoli, 2012).

• Ocular effects: May cause mild pupillary dilation which in susceptible individuals can lead to an episode of narrow-angle glaucoma. Consider evaluating patients who have not had an iridectomy for narrow-angle glaucoma risk factors.

• Serotonin syndrome: Potentially life-threatening serotonin syndrome (SS) has occurred with serotonergic antidepressants (eg, SSRIs, SNRIs), particularly when used in combination with other serotonergic agents (eg, triptans, TCAs, fentanyl, lithium, tramadol, buspirone, St John's wort, tryptophan) or agents that impair metabolism of serotonin (eg, MAO inhibitors intended to treat psychiatric disorders, other MAO inhibitors [ie, linezolid and intravenous methylene blue]). Monitor patients closely for signs of SS such as mental status changes (eg, agitation, hallucinations, delirium, coma); autonomic instability (eg, tachycardia, labile blood pressure, diaphoresis); neuromuscular changes (eg, tremor, rigidity, myoclonus); GI symptoms (eg, nausea, vomiting, diarrhea); and/or seizures. Discontinue treatment (and any concomitant serotonergic agent) immediately if signs/symptoms arise.

• SIADH and hyponatremia: Serotonergic drugs have been associated with the development of SIADH; hyponatremia has been reported (including severe cases with serum sodium <110 mmol/L). Age (the elderly), volume depletion and/or concurrent use of diuretics likely increases risk. Discontinue treatment in patients with symptomatic hyponatremia.

Disease-related concerns:

• Mania/hypomania: May precipitate a mixed/manic episode in patients at risk for bipolar disorder. Use with caution in patients with a family history of bipolar disorder, mania, or hypomania. Patients presenting with depressive symptoms should be screened for bipolar disorder. Vortioxetine is not FDA approved for the treatment of bipolar depression.

• Seizure disorders: Use with caution in patients with seizure disorders, a prior history of seizure disorder, or conditions predisposing to seizures; seizures (rare) have been reported in patients without a prior history of seizures.

Concurrent drug therapy issues:

• Drug-drug interactions: Potentially significant interactions may exist, requiring dose or frequency adjustment, additional monitoring, and/or selection of alternative therapy. Consult drug interactions database for more detailed information.

Other warnings/precautions:

• Discontinuation syndrome: Abrupt discontinuation or interruption of antidepressant therapy has been associated with a discontinuation syndrome. Symptoms arising may vary with antidepressant however commonly include nausea, vomiting, diarrhea, headaches, lightheadedness, dizziness, diminished appetite, sweating, chills, tremors, paresthesias, fatigue, somnolence, and sleep disturbances (eg, vivid dreams, insomnia). Less common symptoms include electric shock-like sensations, cardiac arrhythmias (more common with tricyclic antidepressants), myalgias, parkinsonism, arthralgias, and balance difficulties. Psychological symptoms may also emerge such as agitation, anxiety, akathisia, panic attacks, irritability, aggressiveness, worsening of mood, dysphoria, mood lability, hyperactivity, mania/hypomania, depersonalization, decreased concentration, slowed thinking, confusion, and memory or concentration difficulties. Greater risks for developing a discontinuation syndrome have been associated with antidepressants with shorter half-lives, longer durations of treatment, and abrupt discontinuation. For antidepressants of short or intermediate half-lives, symptoms may emerge within 2 to 5 days after treatment discontinuation and last 7 to 14 days (APA 2010; Fava 2006; Haddad 2001; Shelton 2001; Warner 2006).

Monitoring Parameters

Mental status for depression, suicidal ideation (especially at the beginning of therapy or when doses are increased or decreased), anxiety, social functioning, mania, panic attacks; akathisia; signs/symptoms of serotonin syndrome and/or hyponatremia; hepatic function (baseline).

Pregnancy Considerations

Nonteratogenic effects in the newborn following SSRI/SNRI exposure late in the third trimester include respiratory distress, cyanosis, apnea, seizures, temperature instability, feeding difficulty, vomiting, hypoglycemia, hypo- or hypertonia, hyper-reflexia, jitteriness, irritability, constant crying, and tremor. Symptoms may be due to the toxicity of the SSRIs/SNRIs or a discontinuation syndrome and may be consistent with serotonin syndrome associated with SSRI treatment. Persistent pulmonary hypertension of the newborn (PPHN) has also been reported with SSRI exposure.

The ACOG recommends that therapy with SSRIs or SNRIs during pregnancy be individualized; treatment of depression during pregnancy should incorporate the clinical expertise of the mental health clinician, obstetrician, primary health care provider, and pediatrician (ACOG 2008). According to the American Psychiatric Association (APA), the risks of medication treatment should be weighed against other treatment options and untreated depression. For women who discontinue antidepressant medications during pregnancy and who may be at high risk for postpartum depression, the medications can be restarted following delivery (APA 2010). Treatment algorithms have been developed by the ACOG and the APA for the management of depression in women prior to conception and during pregnancy (Yonkers 2009).

Pregnant women exposed to antidepressants during pregnancy are encouraged to enroll in the National Pregnancy Registry for Antidepressants (NPRAD). Women 18 to 45 years of age or their health care providers may contact the registry by calling 844-405-6185. Enrollment should be done as early in pregnancy as possible.
