Use of antidepressants during pregnancy: a better choice for some.

Mood disorders such as depression are more common among women, especially among pregnant women. Some population-based studies report a 20% prevalence of depression among pregnant women. [1,2] Given this relatively high prevalence, the use of antidepressant medication during pregnancy is not uncommon. A study in the United States reported that at least 10% of pregnant women used antidepressants during pregnancy. [3] However, antidepressants may interfere with fetal growth so there is an ongoing debate about whether or not antidepressants should be used during pregnancy.

Like all medications, antidepressants should be used with caution during pregnancy. The use of antidepressants during pregnancy has been linked to various negative outcomes including miscarriage, pre-term birth, and low birth weight. One study found that within the two weeks of birth, newborns of mothers who used antidepressants during pregnancy were more likely to develop poor neonatal adaptation syndrome (OR=5.07, 95% CI=3.25-7.90), a condition which is characterized by poor temperature control, hypoglycemia, tachypnoea, respiratory distress, nasal congestion or cyanosis and seizures. [4] A systematic review reported a higher risk of developing congenital heart defects among newborns of mothers who used paroxetine during pregnancy (OR=1.36, 95% CI=1.08-1.71); however, this study did not find evidence of an overall association between the use of antidepressants and neonatal birth defects. [5]

Untreated depression during pregnancy has been linked to more pre-term births and less breastfeeding. [6] Depression during pregnancy has also been associated with asthma in newborns, and the severity of depression was positively correlated with the severity of asthma (a dose-response relationship).[7] Moreover, the distress experienced by women with depression who are pregnant is similar to that experienced by women with depression who are not pregnant; the decline in their quality of life, impairment in their social functioning, and their risk of suicide are the same. [8] Therefore, treatment of depression during pregnancy is important for both the mother and the child.

Psychotherapy, specifically interpersonal psychotherapy,[9] has been shown to ameliorate depressive mood in pregnant women. However, this has only been studied among pregnant women with mild to moderate depression, not among those with severe depression for whom antidepressant treatment may be necessary. To date, there has been limited evidence about the effectiveness and safety of antidepressant use during pregnancy. Some experts have reached a consensus that antidepressants should be used to treat severe depression during pregnancy. [10] The Canadian Network for Mood and Anxiety Treatments (CANMAT) Clinical guidelines for the management of major depressive disorder in adults suggest weighing the adverse effects of antidepressants on the fetus (which occur at a low frequency) against the benefits of treatment. The guidelines list fluoxetine and other selective serotonin re-uptake antidepressants (SSRIs) as first-line antidepressants for use during pregnancy, but they also warn of possible neonatal heart defects after the use of fluoxetine.[11] A small-sample prospective study compared neonatal outcomes between 35 pregnant women who used antidepressants (mainly SSRI) with 23 pregnant women who did not. This study found no differences in cognitive functioning, language, and mobility in the babies at 18 months of age.[12] Another case report found no anomalies in the physical or mental development of a nine-month-old infant born to a mother who had taken duloxetine.[13]

We believe that the benefits of antidepressant treatment of pregnant women with depression outweigh the possible risk to the fetus: (a) if the depression is severe (that is, with suicidal ideation or behavior, psychotic symptoms, or a complete loss of appetite), (b) if there is a family history of re-occurring mental disorders, (c) if the individual lacks family or social support, or (d) if moderate depression persists despite psychotherapeutic treatment. Antidepressant use should be considered for the treatment of pregnant women who meet any of these criteria. The pros and cons of antidepressant treatment should be discussed with the individuals and their family members before obtaining their informed consent.

Currently, most guidelines recommend the use of SSRIs (e.g., fluoxetine and citalopram) or tricyclic antidepressants (e.g., nortriptyline) for depression during pregnancy. Psychiatrists should ensure that the depressed woman and her family members are aware of the potential risks and immediately report any related symptoms. Psychiatrists treating pregnant women also need to coordinate their treatment with the responsible obstetrician to ensure the timely prevention of possible negative outcomes.
