Antidepressant Treatment During Pregnancy: One Woman’s Experience (Part II)
Part 2: Pregnancy
Part 1:Â Pre-Pregnancy Planning
In a recent study by Gerardin and colleagues, the authors note that more research has been done to demonstrate the consequences of postpartum depression than depression during pregnancy (also called antenatal or prenatal depression). Infants born to mothers with depression during pregnancy have been demonstrated to have lower scores on motor behavior and more crying and irritability. Few studies, however, have assessed the longer-term effects of antenatal depression.
Few studies have focused on anxiety disorders in the perinatal period. While various studies have measured levels of anxiety or distress during pregnancy, most studies have relied upon self-report questionnaires to assess for anxiety. In contrast, few studies have used standardized diagnostic criteria to determine the prevalence of anxiety disorders in pregnant populations.  In a recent study, Buist and colleagues studied the prevalence and course of generalized anxiety disorder (GAD) in a prospectively ascertained population of pregnant women.
Ms. T is a 33 year old woman with a history of recurrent depression who is 32 weeks   pregnant with her first pregnancy. She has remained on her citalopram (Celexa) throughout pregnancy and has been well. Her gynecologist has encouraged her to enquire about coming off the Celexa prior to delivery in order to avoid symptoms of neonatal distress. What should she do?
During fetal life, neurons proliferate, migrate and form connections, providing the structure of the developing brain. Neurons reach their final destinations by the 16th week of gestation, while branching and making appropriate connections occur even before that time (1). The brain continues to develop during the entire pregnancy, with most of the synapse formation in the developing brain happens during the third trimester (2).
In the November issue of Obstetrics & Gynecology, The American College of Obstetricians and Gynecologists (ACOG) has issued recommendations to providers regarding efforts to support smoking cessation in pregnant and postpartum women.
In the July 2010 issue of Current Psychiatry, you will find a thorough review on the evaluation and treatment of insomnia in women across the life cycle. The bottom line is that many women experience insomnia during times of hormonal transition. The authors provide some useful guidelines for evaluating women who present with sleep problems (taken from Table 2):
About half of all pregnancies are unplanned. In this situation, many women who conceive while on psychotropic medications decide to abruptly stop their medications when they discover they are pregnant.  While this may seem like the safest option, in terms of protecting the developing fetus, we have data demonstrating high rates of relapse in women who discontinue antidepressant medications or mood stabilizers proximate to conception. We now have data (from several studies in non-pregnant populations) to indicate that the rate of medication discontinuation (abrupt vs. gradual) may also affect risk of relapse.
Increased muscle tone, jitteriness, sleep disturbance, irritability, feeding problems, mild respiratory distress and myoclonus have been reported as symptoms of a potential neonatal distress syndrome related to exposure to SSRIs in late pregnancy. The average duration of symptoms reported is 48 hours. It is estimated that between 25-30% of SSRI-exposed infants are at risk for this syndrome. No treatment intervention is required. Reassuringly, follow-up studies have shown that at 2, 4, 6, and 8 months SSRI-exposed infants are indistinguishable from control infants without known exposure.
