Teratogenicity with Olanzapine

Olanzapine, a 2(nd) generation antipsychotic, is in use in the clinical practice for nearly a decade and a half now. It is classified as a category C drug with very few reports of its toxic effects on the fetus. In general, the risk benefit analysis warrants its use in pregnancy. We report a case of microcephaly and anopthalmos associated with the use of olanzapine in pregnancy. Although a causal role cannot be unequivocally proven, it calls for larger studies to explore this issue.
