Version January 2024
Antidepressants increased the risk of suicidal thoughts and behavior in pediatric and young adult patients in short-term studies. Closely monitor all antidepressant-treated patients for clinical worsening, and for emergence of suicidal thoughts and behaviors. Vortioxetine is not approved for use in pediatric patients.
Major depressive disorder (unipolar) (alternative agent): Oral: Initial: 5 to 10 mg once daily; may increase daily dose based on response and tolerability in increments of 5 to 10 mg at ≥1-week intervals up to target dose of 20 mg once daily (usual maximum dose: 20 mg/day) (Ref).
Maximum dose in known CYP2D6 poor metabolizers: 10 mg/day.
Discontinuation of therapy: The half-life of vortioxetine is significantly greater than 24 hours, decreasing the risk of withdrawal symptoms. Although few withdrawal symptoms due to abrupt discontinuation of vortioxetine have been described, it is recommended that patients receiving 15 or 20 mg/day be tapered to 10 mg/day for 1 week before full discontinuation (Ref). Patients with a prior history of antidepressant withdrawal symptoms or on a high dose may require a slower taper (eg, over 4 weeks) (Ref). If intolerable withdrawal symptoms occur, resume the previously prescribed dose and/or decrease dose at a more gradual rate (Ref). Select patients (eg, those with a history of discontinuation syndrome) on long-term treatment (>6 months) may benefit from tapering over >3 months (Ref). Evidence supporting ideal taper rates is limited (Ref).
Switching antidepressants: Evidence for ideal antidepressant switching strategies is limited; strategies include cross-titration (gradually discontinuing the first antidepressant while at the same time gradually increasing the new antidepressant) and direct switch (abruptly discontinuing the first antidepressant and then starting the new antidepressant at an equivalent dose or lower dose and increasing it gradually). Cross-titration (eg, over 1 to 4 weeks, depending upon sensitivity to discontinuation symptoms and adverse effects) is standard for most switches but is contraindicated when switching to or from a monoamine oxidase inhibitor (MAOI). A direct switch may be an appropriate approach when switching to another agent in the same or similar class (eg, when switching between a selective serotonin reuptake inhibitor and vortioxetine), when the antidepressant to be discontinued has been used for <1 week, or when the discontinuation is for adverse effects. When choosing the switch strategy, consider the risk of discontinuation symptoms, potential for drug interactions, other antidepressant properties (eg, half-life, adverse effects, pharmacodynamics), and the degree of symptom control desired (Ref).
Switching to or from an MAOI:
Allow 14 days to elapse between discontinuing an MAOI and initiation of vortioxetine.
Allow 21 days to elapse between discontinuing vortioxetine and initiation of an MAOI. Due to prolonged washout in patients who are obese (BMI ≥35 kg/m2), consider allowing 32 days to elapse between discontinuing vortioxetine and initiating an MAOI (Ref).
Dosage adjustment for concomitant therapy: Significant drug interactions exist, requiring dose/frequency adjustment or avoidance. Consult drug interactions database for more information.
No dosage adjustment necessary.
No dosage adjustment necessary.

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).
Antidepressants (when used as monotherapy) may precipitate a mixed/manic episode in patients with bipolar disorder. A mixed/manic mood switch has been reported in a patient receiving vortioxetine who was also receiving maintenance medications for bipolar disorder (Ref). Treatment-emergent mania or hypomania has also been reported rarely in patients with unipolar major depressive disorder (MDD) receiving vortioxetine, as many cases of bipolar disorder present in episodes of MDD (Ref).
Mechanism: Non–dose-related; idiosyncratic. Unclear to what extent mood switches represent an uncovering of unrecognized bipolar disorder or a more direct pharmacologic effect independent of diagnosis (Ref).
Onset: Intermediate; among the limited case reports involving vortioxetine, the time until onset of mania/hypomania following initiation or a dose increase varied from 7 to 14 days (Ref).
Risk factors:
Antidepressants in general:
• Family history of bipolar disorder (Ref)
• Depressive episode with psychotic symptoms (Ref)
• Younger age at onset of depression (Ref)
• Antidepressant resistance (Ref)
• Female sex (Ref)
Serotonergic antidepressants, such as selective serotonin reuptake inhibitors (SSRIs) and serotonin norepinephrine reuptake inhibitors (SNRIs), may increase the risk of bleeding, particularly if used concomitantly with antiplatelets and/or anticoagulants. Vortioxetine, a multimodal antidepressant with serotonergic activity, may also increase the risk of bleeding, although data are limited. For SSRIs, multiple observational studies have found an association with SSRI use and a variety of bleeding complications, although prospective studies have not determined if the cause of the increased risk of bleeding is due to SSRI use alone (Ref).
Mechanism: SSRIs are believed to affect bleeding via inhibition of serotonin-mediated platelet activation (inhibition of the reuptake of serotonin into platelets leading to depletion of platelet serotonin thereby resulting in subsequent platelet dysfunction). Vortioxetine’s mechanism has not been fully elucidated but is believed to be multimodal with inhibition of serotonin (5-HT) reuptake and via direct modulation of various serotonin receptors as a 5-HT3, 5-HT7 and 5-HT1D receptor antagonist, a 5-HT1B partial agonist, and a 5HT1A agonist (Ref). Vortioxetine is hypothesized to have high serotonin transporter binding affinity (Ref).
Onset: Varied; based on data evaluating SSRIs, it has been suggested that the onset of risk is likely delayed for several weeks until SSRI-induced platelet serotonin depletion becomes clinically significant (Ref), although the onset of bleeding may be more unpredictable if patients are taking concomitant antiplatelets, anticoagulants, or nonsteroidal anti-inflammatory drugs (NSAIDs).
Risk factors:
• Concomitant use of antiplatelets and/or anticoagulants (based on SSRI-derived literature) (Ref)
• Concomitant use of NSAIDs (based on SSRI-derived literature) (Ref)
• Preexisting platelet dysfunction or coagulation disorders (eg, von Willebrand factor) (based primarily on SSRI-derived literature) (Ref)
Limited data from observational studies involving mostly older adults (≥50 years of age) suggest antidepressant use may be associated with an increased risk of bone fractures. The antidepressants evaluated in the literature predominantly involve the selective serotonin reuptake inhibitors (SSRIs) and the tricyclic antidepressants (TCAs), followed to a lesser extent by the serotonin norepinephrine reuptake inhibitors (SNRIs) (Ref). To date, data are too limited to determine whether an association with fractures and vortioxetine, a multimodal antidepressant with serotonergic activity, exists although a rare case of stress fracture has been observed with use (Ref).
Mechanism: Time-related; based on mostly SSRI-derived literature, the mechanism has not been fully elucidated, although postulated to be through a direct effect by serotonergic agents on bone metabolism via interaction with 5-HT and osteoblast, osteocyte, and/or osteoclast activity (Ref). SSRIs may also contribute to fall risk, contributing to the incidence of fractures (Ref). Of note, data are too limited to determine whether an association exists with vortioxetine and fractures.
Onset: Delayed; using data on mostly SSRI-derived literature, risk appears to increase after initiation and may continue to increase with long-term use. A meta-analysis found risk of fracture increased from 2.9% over 1 year to 5.4% over 2 years; within 5 years, risk increased to 13.4% (Ref). Of note, data are too limited to determine whether an association exists with vortioxetine and fractures.
Risk factors:
• Long-term use (potential risk factor) (SSRI-derived literature) (Ref). Of note, data are too limited to determine whether an association exists with vortioxetine and fractures.
Antidepressants (selective serotonin reuptake inhibitors [SSRIs] most commonly) are associated with syndrome of inappropriate antidiuretic hormone secretion (SIADH) and/or hyponatremia (including severe cases), predominantly in older adults (Ref). Hyponatremia has been reported rarely with vortioxetine (Ref).
Mechanism: Antidepressants may cause SIADH via release of antidiuretic hormone (ADH) (Ref) or may cause nephrogenic SIADH by increasing the sensitivity of the kidney to ADH (Ref).
Onset: Intermediate; based on data involving SSRIs, hyponatremia usually develops within the first few weeks of treatment (Ref).
Risk factors:
Based on data involving SSRIs, risk factors include:
• Older age (Ref)
• Females (Ref)
• Concomitant use of diuretics (Ref)
• Low body weight (Ref)
• Lower baseline serum sodium concentration (Ref)
• Volume depletion (Ref)
• History of hyponatremia (potential risk factors) (Ref)
• Symptoms of psychosis (potential risk factors) (Ref)
Antidepressants (selective serotonin reuptake inhibitors [SSRIs] and serotonin norepinephrine reuptake inhibitors [SNRIs] most commonly implicated) are associated with acute angle-closure glaucoma (AACG) in case reports. AACG may cause symptoms including eye pain, changes in vision, swelling, and redness, which can rapidly lead to permanent blindness if not treated (Ref). Data are too limited to determine if vortioxetine, a multimodal antidepressant with serotonergic activity, is associated with an increased risk for AACG.
Mechanism: Unclear; hypothesized that serotonergic antidepressants like SSRIs may increase the intraocular pressure via serotonergic effects on ciliary body muscle activation and pupil dilation (Ref).
Risk factors:
Based on SSRI- and SNRI-derived literature:
• Females (Ref)
• ≥50 years of age (slight increase) (Ref)
• Hyperopia (slight increase) (Ref)
• Personal or family history of AACG (Ref)
• Inuit or Asian descent (Ref)
Serotonin syndrome has been reported with serotonergic agents, including rarely with vortioxetine, and typically occurs with coadministration of multiple serotonergic drugs. There is also a case report of serotonin syndrome occurring in a patient receiving vortioxetine at therapeutic doses and without any concomitant serotonergic agents (Ref). The diagnosis of serotonin syndrome is made based on the Hunter Serotonin Toxicity Criteria (Ref) and may result in a spectrum of symptoms, such as anxiety, agitation, confusion, delirium, hyperreflexia, muscle rigidity, myoclonus, tachycardia, tachypnea, and tremor. Severe cases may cause hyperthermia, significant autonomic instability (ie, rapid and severe changes in blood pressure and pulse), coma, and seizures (Ref).
Mechanism: Dose-related; overstimulation of serotonin receptors by serotonergic agents (Ref).
Onset: Rapid; in most serotonin-syndrome cases (74%) (predominantly involving selective serotonin reuptake inhibitors, tricyclic antidepressants, and/or monoamine oxidase inhibitors [MAOIs]), onset occurred within 24 hours of treatment initiation, overdose, or change in dose (Ref).
Risk factors:
• Concomitant use of drugs that increase serotonin synthesis, block serotonin reuptake, and/or impair serotonin metabolism (eg, MAOIs). Of note, concomitant use of some serotonergic agents, such as MAOIs, are contraindicated.
• Obesity (potential risk factor due to the prolongation of half-life observed in individuals with obesity compared to individuals without obesity) (Ref)
Antidepressants, primarily the selective serotonin reuptake inhibitors (SSRIs), are commonly associated with male sexual disorder and female sexual disorder. Vortioxetine, a multimodal antidepressant with serotonergic activity, is typically associated with either low rates of treatment-emergent sexual dysfunction or incidences comparable to placebo in the few clinical trials available. In addition, limited data suggest that vortioxetine may have some beneficial effects on sexual functioning in depressed patients who switched from an antidepressant with high rates of dysfunction to vortioxetine. However, treatment-emergent sexual dysfunction is typically underreported and clinical benefit on sexual functioning is difficult to ascertain in clinical trials (Ref).
Mechanism: The mechanism attributed to vortioxetine’s role (if any) in sexual dysfunction is unknown; however, using literature involving SSRIs, it has been postulated that increases in serotonin may affect other hormones and neurotransmitters involved in sexual function. Vortioxetine is a multimodal antidepressant with serotonergic activity through direct modulation of 5-HT receptors and inhibition of serotonin reuptake (Ref).
Risk factors:
• Depression (sexual dysfunction is commonly associated with depression; antidepressant-induced sexual dysfunction may be difficult to differentiate in treated patients) (Ref)
Antidepressants are associated with an increased risk of suicidal ideation and suicidal tendencies in pediatric and young adult patients (18 to 24 years) in short-term studies. In adults >24 years of age, short-term studies did not show an increased risk of suicidal thinking and behavior, and in older adults ≥65 years of age, a decreased risk was observed. Although data have yielded inconsistent results regarding the association of antidepressants and risk of suicide, particularly among adults, collective evidence shows a trend of an elevated risk of suicidality in younger age groups (Ref). Of note, the risk of a suicide attempt is inherent in major depression and may persist until remission occurs.
Mechanism: Not established; one of several postulated mechanisms is antidepressants may energize suicidal patients to act on impulses; another suggests that antidepressants may produce a worsening of depressive symptoms, leading to the emergence of suicidal thoughts and actions (Ref).
Onset: Varied; increased risk observed in short-term studies (ie, <4 months) in pediatric and young adults; it is unknown whether this risk extends to longer-term use (ie, >4 months).
Risk factors:
• Children and adolescents (Ref)
• Depression (risk of suicide is associated with major depression and may persist until remission occurs)
Withdrawal syndrome, consisting of both somatic symptoms (eg, dizziness, chills, light-headedness, vertigo, shock-like sensations, paresthesia, fatigue, headache, nausea, tremor, diarrhea, visual disturbances) and psychological symptoms (eg, anxiety, agitation, confusion, insomnia, irritability, mania), have been reported with serotonergic antidepressants, primarily following abrupt discontinuation. Withdrawal symptoms may also occur following gradual tapering. In general, antidepressant discontinuation symptoms usually last a few weeks, but occasionally may persist for months or possibly even years (ie, persistent postwithdrawal disorder) (Ref). Data from clinical trials and observational data with vortioxetine specifically suggest that discontinuation symptoms may occur, particularly with abrupt withdrawal, but the incidence is low and/or similar to placebo, possibly due to its relatively long half-life (Ref).
Mechanism: Withdrawal; due to reduced availability of serotonin in the CNS with decreasing levels of the serotonergic agent. Other neurotransmission systems, including increased glutamine and dopamine, may also be affected, as well as the hypothalamic-pituitary-adrenal axis (Ref).
Onset: Rapid; in literature derived from selective serotonin reuptake inhibitors or serotonin norepinephrine reuptake inhibitors discontinuation, symptom onset usually occurs within a few days after discontinuation (Ref). In a small number of patients (n=8) from the retrospective chart review of vortioxetine experiencing discontinuation symptoms (primarily those who discontinued therapy without medical consultation), onset was 3 days following therapy withdrawal and symptoms lasted for a median of 7 days (Ref).
Risk factors:
• Abrupt discontinuation (rather than gradual dosage reduction) of an antidepressant treatment that has lasted for >3 weeks, particularly a drug with a half-life <24 hours (eg, paroxetine, venlafaxine) (Ref). Of note, vortioxetine has a long half-life (~66 hours in adults) (Ref)
• Prior history of antidepressant withdrawal symptoms (Ref)
• High dose (Ref)

Significant drug interactions exist, requiring dose/frequency adjustment or avoidance. Consult drug interactions database for more information.
Major psychiatric warnings:
• Suicidal thinking/behavior: Consider risk prior to prescribing. Short-term studies did not show an increased risk in patients >24 years of age and showed a decreased risk in patients ≥65 years of age. Instruct the patient's family or caregiver to closely observe the patient and communicate condition with health care provider, particularly during the first few months of therapy or during periods of dose adjustments. A medication guide concerning the use of antidepressants should be dispensed with each prescription.
-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. Risk of postpartum bleeding may be increased with SSRI use, particularly in the month prior to delivery. 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, meperidine, methadone, tramadol, buspirone, amphetamines, 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: Screen patients for history or family history of bipolar disorder, mania, or hypomania prior to initiating therapy; may precipitate a shift to mania or hypomania in patients with bipolar disorder. Monotherapy in patients with bipolar disorder should be avoided. Combination therapy with an antidepressant and a mood stabilizer may be effective for acute treatment of bipolar major depressive episodes, but should be avoided in acute mania or mixed episodes, as well as maintenance treatment in bipolar disorder due to the mood-destabilizing effects of antidepressants (CANMAT [Yatham 2018]; WFSBP [Grunze 2018]). 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.
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).

Vortioxetine is approved for the treatment of unipolar major depressive disorder. If treatment for major depressive disorder is initiated for the first time in patients planning to become pregnant, vortioxetine is not a preferred antidepressant (Larsen 2015).
Vortioxetine may be associated with male and female treatment-emergent sexual dysfunction. Sexual dysfunction has been reported in males and females following vortioxetine use.
Information specific to vortioxetine use in pregnancy is limited (Shweiki 2021).
Vortioxetine shares some properties of selective serotonin reuptake inhibitors (SSRIs); additionally, it modulates other serotoninergic activity. As a class, SSRIs have been evaluated extensively in pregnant patients. Studies focusing on newborn outcomes following first trimester exposure often have inconsistent results due to differences in study design and confounders such as maternal disease and social factors (Anderson 2020; Biffi 2020; Fitton 2020; Reefhuis 2015; Womersley 2017).
Adverse effects in the newborn following SSRI exposure late in the third trimester can include apnea, constant crying, cyanosis, feeding difficulty, hyperreflexia, hypo- or hypertonia, hypoglycemia, irritability, jitteriness, respiratory distress, seizures, temperature instability, tremor, and vomiting. Prolonged hospitalization, respiratory support, or tube feedings may be required. Symptoms may be due to the toxicity of the SSRIs or a discontinuation syndrome and may be consistent with serotonin syndrome associated with SSRI treatment. Persistent pulmonary hypertension of the newborn has been reported with SSRI exposure; although the absolute risk is small, monitoring of infants exposed to SSRIs late in pregnancy is recommended (Masarwa 2019; Ng 2019). The long-term effects of in utero SSRI exposure on infant neurodevelopment and behavior are not known (CANMAT [MacQueen 2016]).
If treatment for major depressive disorder is initiated for the first time during pregnancy, vortioxetine is not one of the preferred antidepressants (CANMAT [MacQueen 2016]; Larsen 2015; WFSBP [Bauer 2013]). Untreated or inadequately treated psychiatric illness may lead to poor adherence with prenatal care and adverse pregnancy outcomes. Therapy with antidepressants during pregnancy should be individualized; treatment with antidepressant medication is recommended for pregnant patients with severe major depressive disorder (ACOG 2008; CANMAT [MacQueen 2016]). Patients treated for major depression and who are euthymic prior to pregnancy are more likely to experience a relapse when medication is discontinued (68%) as compared to pregnant patients who continue taking antidepressant medications (26%) (Cohen 2006).
Data collection to monitor pregnancy and infant outcomes following exposure to antidepressant medications is ongoing. Patients exposed to antidepressants during pregnancy are encouraged to enroll in the National Pregnancy Registry for Antidepressants. Pregnant patients 18 to 45 years of age or their health care providers may contact the registry to enroll; enrollment should be done as early in pregnancy as possible (1-866-961-2388 or https://womensmentalhealth.org/research/pregnancyregistry/antidepressants/).
Vortioxetine is present in breast milk.
Information related to the presence of vortioxetine in breast milk is available from 3 lactating women 1 to 6 months postpartum. Breast milk was sampled prior to and at intervals for 24 hours after the dose. All patients were at steady state and exclusively breastfeeding their infants:
- Following a dose of vortioxetine 10 mg/day (n = 2), the maximum breast milk concentration was 13.89 ng/mL and occurred 7 hours after the dose. Based on this information, authors of the study calculated the relative infant dose (RID) of vortioxetine to be 1.1%, providing an estimated daily infant dose via breast milk of 0.0017 mg/kg/day, based on the weight-adjusted maternal dose.
- Following a dose of vortioxetine 20 mg/day (n = 1), the maximum breast milk concentration was 52.32 ng/mL and occurred 5 hours after the dose. Based on this information, the authors of the study calculated the RID of vortioxetine to be 1.7%, providing an estimated daily infant dose via breast milk of 0.0052 mg/kg/day (Marshall 2021).
- In general, breastfeeding is considered acceptable when the RID of a medication is <10% (Anderson 2016; Ito 2000).
Vortioxetine shares some properties of selective serotonin reuptake inhibitors (SSRIs); additionally, it modulates other serotoninergic activity. Infants exposed to an SSRI via breast milk should be monitored for irritability and changes in sleep, feeding patterns, and behavior as well as growth and development (ABM [Sriraman 2015]; Sachs 2013; Weissman 2004; WFSBP [Bauer 2013]).
Maternal use of an SSRI during pregnancy may cause delayed lactogenesis (Marshall 2010); however, the underlying maternal illness may also influence this outcome (Grzeskowiak 2018). Untreated severe or chronic depression in the postpartum period also has negative effects on the mother and the infant (Slomian 2019).
Psychotherapy or other nonmedication therapies are recommended for the initial treatment of mild depression in breastfeeding patients; however, antidepressant medication is recommended when psychotherapy is not an option or when symptoms are moderate to severe. If a specific SSRI was used effectively during pregnancy, it can be continued while breastfeeding if no contraindications exist (ABM [Sriraman 2015]). According to the manufacturer, the decision to breastfeed during vortioxetine therapy should consider the risk of infant exposure, the benefits of breastfeeding to the infant, and benefits of treatment to the mother. When first initiating an antidepressant in a patient who is breastfeeding, agents other than vortioxetine are preferred (ABM [Sriraman 2015]; CANMAT [MacQueen 2016]; Larsen 2015).
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.
Inhibits reuptake of serotonin (5-HT); also has agonist activity at the 5-HT1A receptor and antagonist activity at the 5-HT3 receptor. Additionally, vortioxetine is a weak antagonist at 5-HT7 and 5-HT1D receptors, as well as a partial agonist at 5-HT1B receptors (Bang-Andersen 2011; Kelliny 2015).
Onset of action: Depression: Initial effects may be observed within 1 to 2 weeks of treatment, with continued improvements through 4 to 6 weeks (Papakostas 2006; Posternak 2005; Szegedi 2009; Taylor 2006).
