Is Invega Safe in Breastfeeding

I am a breastfeeding mother and i want to know if it is safe to use Invega? Is Invega safe for nursing mother and child? Does Invega extracts into breast milk? Does Invega has any long term or short term side effects on infants? Can Invega influence milk supply or can Invega decrease milk supply in lactating mothers?

Risperidone and its metabolite (Invega) 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 Invega: oral and intramuscular (Depo). Depo type (Invega 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.

Although no data are available for the use of Invega during breastfeeding, it is the active metabolite of risperidone. Risperidone data indicate that the concentrations of Invega (9-hydroxyrisperidone) in breastmilk are low, and amounts ingested by the infant are small. Because there is no published experience with Invega during breastfeeding and little long-term follow-up data, other agents may be preferred, especially while nursing a newborn or preterm infant. Because Invega is available only as a sustained-release product, timing of nursing with respect to doses would not be useful.

No published information on Invega was found as of the revision date. However, limited data from the use of its parent drug, risperidone, during nursing indicate no short- or long-term adverse effects on the infant.[3][4][5]

Invega has caused elevated prolactin serum levels, gynecomastia, and galactorrhea in patients taking the drug.[6][7][8][9][10][11] The prolactin level in a mother with established lactation may not affect her ability to breastfeed.
