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).

Lamotrigine and Breastfeeding

Because rates of postpartum illness are very high in women with bipolar disorder, it is generally recommended that mothers continue treatment with a mood stabilizer throughout the postpartum period to reduce their risk of relapse; however, the use of medications during the postpartum period is complicated by the issue of breastfeeding. All medications are secreted into the breast milk, although their concentrations appear to vary (Chaudron and Jefferson, 2000).

Can Women Taking Lithium Breastfeed Their Infants?

It is clear that women with bipolar disorder are at high risk for relapse during the immediate postpartum period (Viguera 2000). There is evidence that the resumption of lithium prior to or within 24-48 hours of delivery can significantly reduce the risk of postpartum illness (Cohen 1995). While this intervention is the current standard of care for this high risk population, women have historically been instructed to avoid breastfeeding while taking lithium based on early reports suggesting high levels of lithium in the breast milk and several cases of lithium toxicity in nursing infants (Schou 1973). While the American Academy of Pediatrics guidelines are less restrictive in their current recommendation, they do urge caution. However, systematic studies regarding the levels of exposure to lithium in nursing infants and the potential risks of this exposure have been lacking.

Anticonvulsants During Pregnancy in Women with Bipolar Disorder

Unfortunately the mood stabilizers most commonly used to treat bipolar disorder (including lithium and valproic acid) can increase the risk of certain types of congenital malformations in children exposed to these medications during the first trimester of pregnancy. For women who need a mood stabilizer during pregnancy, lithium is the safest option; however, when used during the first trimester, it carries a 0.1% risk of a cardiac malformation called Ebstein's anomaly. Although this is a potentially serious complication, it is important to keep in mind that the risk of malformation is relatively small.

Lithium Discontinuation While Attempting to Conceive

For women with bipolar disorder who are planning a pregnancy, it is common practice to discontinue mood stabilizers prior to attempts to conceive, since the mood stabilizers most commonly used to treat bipolar disorder (lithium, valproic acid, and carbamazepine) all carry some risk of birth defect. The problem with this approach is that, after discontinuation of maintenance treatment, a woman is at very high risk for relapse. The longer it takes to get pregnant and the longer she remains off medication, the greater is her risk for having recurrent illness.
