Neurobehavioral Outcomes in Children Exposed to Lithium in Utero
Driven by concerns regarding fetal exposure to psychotropic medications, many women with psychiatric illness attempt to discontinue their pharmacologic treatment during pregnancy; however, recent studies indicate that this approach may not be appropriate for all women. Dr. Adele Viguera and her colleagues at the Center for Women’s Mental Health have reported that among pregnant women with bipolar disorder, relapse rates were very high (58%) in women who discontinued maintenance treatment with lithium during pregnancy (Viguera et al 2000). Given this risk of recurrent illness, many women may consider continuing lithium treatment during pregnancy. While the teratogenic effects of first trimester exposure to lithium have been well studied, data on the long-term outcome of children exposed to lithium during pregnancy are sparse. At the 61st Annual Meeting of the Society of Biological Psychiatry in Toronto, Dr. Viguera presented preliminary data on the neurobehavioral outcomes of children exposed to lithium in utero.
Evaluating the Safety of First-Trimester Exposure to Lamotrigine (Lamictal)
Early reports suggested that women with bipolar disorder may be at lower risk for onset or relapse of this disorder during pregnancy and that some women may be able to remain well during pregnancy despite medication discontinuation. However, more recent studies have suggested that recurrence of affective illness during pregnancy is relatively common among women with bipolar disorder. Dr. Adele Viguera and her colleagues at the Center for Women's Mental Health reported that among pregnant bipolar women, relapse rates were very high (58%) in those women who discontinued maintenance treatment with lithium during pregnancy (Viguera et al 2000).
Menstrual Cycle Irregularity in Women with Bipolar Disorder
Preliminary reports have suggested that menstrual irregularity may occur more commonly in women with mood disorders than in the general population. What has been unclear, however, is whether these menstrual cycle irregularities reflect an underlying disruption of the hypothalamic-pituitary-gonadal (HPG) axis in women with mood disorders or are caused by the psychotropic medications used to treat these psychiatric disorders.In a recent study, Dr. Hadine Joffe of the Center for Women’s Mental Health and her colleagues assessed the prevalence of menstrual cycle dysfunction in 3 groups of women: (1) with bipolar disorder, (2) with unipolar depression, or (3) with no psychiatric illness (Joffe 2006).
Use of Paxil during Pregnancy
Q. I have taken Paxil for about six years for depression and obsessive-compulsive disorder. I have tried several times to stop the medication but the symptoms come back within a few weeks of stopping the medication. My husband and I are now planning a pregnancy, and my obstetrician tells me that I cannot take Paxil during pregnancy. Are there any other options?
Withdrawal Symptoms in Newborns Exposed to SSRIs
A recent report suggests that newborns exposed to selective serotonin reuptake inhibitors (SSRI) antidepressants such as Prozac, Zoloft, Celexa and Paxil may be at risk for developing withdrawal symptoms after delivery (Levinson-Castiel 2005). However, the investigators also noted that the symptoms usually disappeared within 48 hours and did not require medical intervention.
SSRIs and Persistent Pulmonary Hypertension of the Newborn
These findings are likely to generate significant anxiety among child-bearing women who suffer from depression who would like to maintain antidepressant medication during pregnancy. Future studies are needed to better understand the risk of PPHN in this setting.
