Category: Breastfeeding safety

According to the Centers for Disease Control and Prevention (CDC), while most medications do pass into breast milk, most do so in such tiny amounts that they have little or no effect on the infant. However, the amount and potential for harm vary significantly depending on the drug, making it vital to understand **which drugs are excreted through breast milk** and the factors influencing this process.

Maternal doses of olanzapine up to 20 mg daily typically produce low levels in breast milk and often result in undetectable drug concentrations in a breastfed infant's blood. The complex decision of whether it is safe to continue breastfeeding while taking olanzapine hinges on a careful, individualized risk-benefit assessment with a healthcare provider.
