Paliperidone

Although no published data are available for the use of paliperidone during breastfeeding, the manufacturer reported milk levels indicating that an infant would receive about 1% of the maternal weight-adjusted dosage. Paliperidone is the active metabolite of risperidone. Risperidone data indicate that the concentrations of paliperidone (9-hydroxyrisperidone) in breastmilk are low, and amounts ingested by the infant are small. A safety scoring system finds paliperidone possible to use cautiously during breastfeeding,[1] although others do not recommend it.[2] Because there is no published experience with paliperidone during breastfeeding and little long-term follow-up data, other agents may be preferred, especially while nursing a newborn or preterm infant. Because paliperidone is available only as long-acting products, timing of nursing with respect to doses would not be useful. Long-acting injectable formulations may continue to deliver small amounts to breastmilk for many months. Monitor breastfed infants for drowsiness, adequate growth and weight gain, jitteriness, tremors, and abnormal movements.
