Long-acting olanzapine injection during pregnancy and breastfeeding: a case report

We present one case of a woman treated with the intramuscular depot formulation of the atypical antipsychotic, olanzapine pamoate (ZypAdhera®), during pregnancy and breastfeeding. Data on olanzapine distribution in breast milk as well as on plasma concentration in the nursed infant are provided. The present case report demonstrates that olanzapine was excreted in the breast milk, but the breast-fed infant had very low olanzapine concentrations, which did not result in any adverse effects.
