Risperidone and its metabolite (Paliperidone) are excreted into breast milk in non-significant amount. Untoward effect has not been observed on breastfed infants of treated mothers. Serum levels were very low or undetectable in these infants. May be a cause of galactorrhea. Thera are two types of Paliperidone: oral and intramuscular (Depo). Depo type (Paliperidone Palmitate) requires intramuscular administration with a Time to Max of 13 days and a Half-time of 25 to 50 days. That would be a reason to use during breastfeeding a non-depot (oral) medication like Risperidone or any suggested alternative, as a safer choice.
