Limited information indicates that maternal risperidone doses of up to 6 mg daily produce low levels in milk. Sedation, failure to thrive, jitteriness, tremors, abnormal muscle movements and respiratory depression have been reported in infants exposed to risperidone in milk. Because there is little published experience with risperidone during breastfeeding and little long-term follow-up data, other agents may be preferred, especially while nursing a newborn or preterm infant. Systematic reviews of second-generation antipsychotics concluded that risperidone seemed to be a second-line agent during breastfeeding because of the limited data available and higher excretion into milk relative to other agents.[1-3] A safety scoring system finds risperidone to be possible to use cautiously during breastfeeding.[4] Monitor the infant for drowsiness, weight gain, tremors, respiratory rate, abnormal muscle movements, and developmental milestones, especially if other antipsychotics are used concurrently.
