SSRIs and Craniosynostosis
Craniosynostosis is a birth defect of the skull in which the cranial joints of the developing baby’s skull close prematurely. The cranial joints (known as the cranial sutures) are fibrous connections between the skull’s bony plates. When the cranial joints close before brain growth is complete, abnormal development of the skull occurs due to the brain’s resulting inability to develop in its normal fashion. The result is growth in other areas of the skull which causes an abnormally shaped skull.
Alwan and colleagues, in their analyses of data from the National Birth Defects Prevention Study (1997-2001), reported an association between the use of SSRIs during pregnancy and craniosynostosis. Analysis of the data revealed an Odds Ratio (OR) of 1.8 which suggests an 80% increase in the risk of having a baby with craniosynostosis for women who used SSRIs during pregnancy.

A study published in the June 28, 2007 issue of the New England Journal of Medicine (NEJM) indicates that maternal use of SSRIs during pregnancy significantly increases the risk of ompahlocele, craniosynostosis and anencephaly. This study (Use of Selective Serotonin-Reuptake Inhibitors in Pregnancy and the Risk of Birth Defects, Alwan et. al.) suggests that the risk of these birth defects is almost tripled (Odds Ratio 2.8) when SSRIs are used during pregnancy. The Study further indicates that the risk of these birth defects is:
- 4.2 times greater with the use of Paxil® during pregnancy
- 4.0 times greater with the use of citralopram during pregnancy
- 2.0 times greater with the use of Zoloft® during pregnancy, and
- 1.9 times greater with the use of Prozac® during pregnancy.
Further analyses of the data by the authors of the Study indicate that the maternal use of Prozac® during pregnancy carries an almost 3-times greater risk of craniosynostosis (Odds Ratio 2.8).
