ABSTRACT To determine the prevalence of persistent pulmonary hypertension of the newborn (PPHN) among infants whose mothers were exposed to antidepressants in the third trimester of pregnancy compared to the prevalence among infants whose mothers were not exposed to antidepressants in the third trimester.
A retrospective study was conducted using the automated databases of four health plans participating in the HMO Research Network Center for Education and Research on Therapeutics. Women who delivered an infant in a hospital from 1 January 1996 through 31 December 2000 were identified. The administrative databases were used to identify full-term infants whose mothers received an antidepressant during the third trimester of pregnancy and unexposed infants whose mothers did not receive an antidepressant during the third trimester. Hospitalization data were used to identify diagnoses or procedure codes potentially indicative of PPHN.
Among 1104 infants exposed to antidepressants in the third trimester and a matched sample of 1104 unexposed infants, five infants were classified by the expert reviewers as having PPHN. Among those infants whose mothers were exposed to selective serotonin reuptake inhibitors (SSRIs) in the third trimester, the prevalence of PPHN was 2.14 per 1000 (95% confidence interval (CI) 0.26, 7.74), while the prevalence among infants whose mothers were not exposed was 2.72 per 1000 (95%CI 0.56, 7.93).
We did not find an association between SSRI use in late pregnancy and PPHN. Limitations of the present study, including the small number of confirmed cases, suggest further research in this area may be warranted.

    ABSTRACT: Introduction: Psychiatric disorders are among the leading causes of disability in Western societies. Selective serotonin reuptake inhibitors (SSRIs) are the most frequently prescribed antidepressant drugs during pregnancy and the postpartum period. Over the last decade, conflicting findings regarding the safety of SSRI drugs during pregnancy and lactation have questioned whether such treatments should be used during this period. Areas covered: We discuss the main criteria that should be considered in the risk/benefit assessment of SSRI treatment in pregnant and/or breastfeeding patients (i.e., risks associated with SSRI use and with untreated depression as well as therapeutic benefits of SSRI and some alternative treatment strategies). For each criterion, available evidence has been synthesized and stratified by methodological quality as well as discussed for clinical impact. Expert opinion: Currently, it is impossible for most of the evaluated outcomes to distinguish between the effects related to the mother's underlying disease and those inherent to SSRI treatment. In women suffering from major depression and responding to a pharmacological treatment, introduction or continuation of an SSRI should be encouraged in order to prevent maternal complications and to preserve maternal-infant bonding. The choice of the right drug depends above all on individual patient characteristics such as prior treatment response, diagnoses and comorbid conditions.

    ABSTRACT: In pregnant women with major depression, the overarching goal of treatment is to achieve or maintain maternal euthymia, thus limiting both maternal and fetal exposure to the harmful effects of untreated or incompletely treated depression. However, the absence of uniformly effective therapies with guaranteed obstetric and fetal safety makes the treatment of major depression during pregnancy among the most formidable of clinical challenges. Clinicians and patients are still faced with conflicting data and expert opinion regarding the reproductive safety of antidepressants in pregnancy, as well as large gaps in our understanding of the effectiveness of most antidepressants and nonpharmacological alternatives for treating antenatal depression. In this paper, we provide a clinically focused review of the available information on potential maternal and fetal risks of untreated maternal depression during pregnancy, the effectiveness of interventions for maternal depression during pregnancy, and potential obstetric, fetal, and neonatal risks associated with antenatal antidepressant use.

    ABSTRACT: There is controversy about the use of antidepressant medication during pregnancy. Decisions about their use are affected by understanding the risks of these medications causing pregnancy loss, congenital malformations, neonatal adaptation syndrome, persistent pulmonary hypertension of the newborn, autism spectrum disorder, or long-term neurocognitive deficits. Although some research has raised concerns about antidepressants causing harm to the fetus and neonate, other studies have disputed these findings or noted that any risks found do not exceed the risk of congenital problems found in 1% to 3% of neonates in the general population. Untreated depression during pregnancy can also cause harm from poor diet, substance abuse, suicidal behavior, or prematurity. Decisions about the use of antidepressants during pregnancy must be based on a risk-benefit analysis based on the best evidence of the risks of treating or not treating maternal depression.
