Prozac hit the market in 1988, the first selective serotonin reuptake inhibitor (SSRI) antidepressant approved by the FDA for the treatment of depression. Because it was safer and more tolerable than the antidepressants that preceded it, Prozac was soon the most commonly prescribed antidepressant in the United States.
Duloxetine (sold in the United Sates under the brand name of Cymbalta) is a serotonin-norepinephrine reuptake inhibitor (SNRI) effective for major depressive disorder and generalized anxiety disorder (GAD). Although used fairly commonly in women of child-bearing age, information regarding its reproductive safety has been lacking.
While data accumulated over the last 30 years suggest that certain antidepressants may be used with relative safety during pregnancy, our knowledge regarding the risks of prenatal exposure to psychotropic medications is incomplete. Because neuronal migration and differentiation occur throughout pregnancy and into the early years of life, development of the central nervous system (CNS) remains particularly vulnerable throughout pregnancy.
While much research has demonstrated that maternal depression may negatively affect the child, leading to increased risk of developmental delays, behavioral problems, and psychiatric illness. Less research, however, has detailed the impact of paternal depression; several recent studies have focused on better understanding the risk factors for paternal depression and how paternal depression affects children.
About 10-30% of children have functional somatic symptoms (FSS). These are physical complaints, such as headaches, pain, fatigue, and dizziness, that cannot be explained medically. A new study suggests that when a child is exposed to depression or anxiety in the mother during the first year of life, he or she is more likely to report these somatic symptoms later on.
In a recent retrospective cohort study, data collected from linked records from the Women's and Children's Health Network in South Australia were used to investigate neonatal outcomes in children exposed prenatally to selective serotonin reuptake inhibitors (SSRIs). Women were included in this study if they gave birth to a singleton, live-born infant between September 2000 and December 2008 (n = 33,965).
Over the past few years, there have been a large number of studies which have relied on large administrative databases to generate information on the reproductive safety of various medications. One of the strengths of this type of approach is that it provides an opportunity to observe outcomes in a large number of subjects; however, there are certain, very important limitations. A recent study published in the American Journal of Obstetrics and Gynecology helps to understand some of the challenges in interpreting the data generated from these studies.
Some, but not all, studies have indicated that depression during pregnancy increases the risk of preterm birth. A recent study published in the American Journal of Obstetrics and Gynecology is one of the largest to address this question.
Most studies have shown that women experience an improvement or remission in eating disorders during pregnancy; however, studies assessing how eating disorders may affect pregnancy outcomes have yielded conflicting results. While some studies have demonstrated no negative effects, others have demonstrated higher miscarriage rates among women with bulimia nervosa. In addition, women with histories of eating disorders have been shown to be significantly more likely to experience preterm delivery and to give birth to babies small for gestational age.
While we have data on the use of lithium use during pregnancy with regard to risk for congenital malformations, there is much less information on the long-term effects of lithium on neurodevelopment. A recent study from the Perinatal Center of the Leiden University Medical Center provides some reassuring data on the long-term effects of lithium exposure.
