Precautions
Increased risk of suicidal thinking and behavior in children, adolescents, and young adults taking antidepressants for major depressive disorder and other psychiatric disorders
Serotonin Syndrome: Increased risk when co-administered with other serotonergic agents (e.g., SSRI, SNRI, triptans, amphetamines), but also
when taken alone.
Increased Risk of Bleeding: Concomitant use of aspirin, nonsteroidal antiinflammatory drugs (NSAIDs), other antiplatelet drugs, warfarin, and other
anticoagulants may increase this risk.
Activation of Mania/Hypomania: Screen patients for bipolar disorder.
Seizures: Can occur with treatment. Use with caution in patients with a seizure disorder.
Angle Closure Glaucoma: Avoid use of antidepressants, including Vilazodone, in patients with untreated anatomically narrow angles.
Sexual Dysfunction: Vilazodone may cause symptoms of sexual dysfunction
Pregnancy-Lactation
Pregnancy
There are no adequate and well-controlled studies in pregnant women; a prospective, longitudinal study followed 201 pregnant women with a history of major depressive disorder who were euthymic and taking antidepressants at beginning of pregnancy; women who discontinued antidepressants during pregnancy were more likely to experience a 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
Exposure in late pregnancy may lead to 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 therapy in third trimester of pregnancy for PPHN and drug discontinuation syndrome
Persistent pulmonary hypertension of the newborn
Potential risk of PPHN when used during pregnancy
Initial public health advisory in 2006 was based on a single published study; since then, there have been conflicting findings from new studies, making it unclear whether use of SSRIs during pregnancy can cause PPHN
FDA has reviewed the additional new study results and has concluded that, given the conflicting results from different studies, it is premature to reach any conclusion about a possible link between SSRI use in pregnancy and PPHN
FDA recommendation: FDA advises health-care professionals not to alter their current clinical practice of treating depression during pregnancy and to report any adverse events to the FDA MedWatch program
Lactation
There are no data on presence in human milk, effects on breastfed infant, or on milk production; however, drug is excreted in rat milk; developmental and health benefits of breastfeeding should be considered along with mother’s clinical need for therapy and any potential adverse effects on breastfed child from drug or from underlying maternal condition
Interactions

CYP3A4 Inducers: Consider increasing Vilazodone dosage by 2-fold, up to 80 mg once-daily over 1 to 2 weeks when used concomitantly with strong
CYP3A4 inducers for greater than 14 days.
