C17H20N4S

Very Low Risk for breastfeeding


Safe. Compatible.
Not risky for breastfeeding or infant.

It is excreted in breast milk in clinically non-significant amount without problems observed in infants whose mothers were receiving this treatment, whether on psychomotor development, speech improvement and weight gaining.
Drug plasma levels in these infants were undetectable or very low.

In the neonatal period, isolated cases of sedation and / or withdrawal symptoms have been reported, possibly by accumulative mechanism during pregnancy or added effect from another drug.

Some experts think that Olanzapine would be the one of choice during lactation among second-generation antipsychotic drugs (Uguz 2016).

May induce increased plasma levels of Prolactin but less frequently and lower than other antipsychotic drugs.
