Is Periciazine safe while breastfeeding?
Here is what LactMed, the Drugs and Lactation Database published by the U.S. National Institute of Child Health and Human Development (NICHD), reports about Periciazine. The text below is quoted from that source — it is not our own verdict.
Summary of use during breastfeeding
Propericiazine and its active metabolite periciazine are not approved for marketing in the United States by the U.S. Food and Drug Administration, but are available in other countries. Minimal information from one patient indicates that the amount of periciazine is low in milk after administration of propericiazine. If propericiazine or periciazine is required by the mother, it is not a reason to discontinue breastfeeding, but until more data become available, an alternate drug may be preferred, especially while nursing a newborn or preterm infant.

Propericiazine is metabolized to the active drug, periciazine in the body.
Maternal Levels. A woman with dissociative disorder and persistent dysthymic depression was treated during pregnancy with brotizolam 0.25 mg daily, propericiazine 10 mg daily, and zolpidem 5 mg daily. Zolpidem was discontinued at week 28 and sulpiride 100 mg daily was begun at week 33. Milk samples taken at 7.5 and 11.5 hours after the previous dose on day 9 postpartum contained 0.3 and 0.1 mcg/L of periciazine, respectively.[1]
Infant Levels. Relevant published information was not found as of the revision date.
Alternatives LactMed lists
“No published information” means the studies do not exist yet — not that Periciazine is known to be harmful, and not that it is known to be safe. Your prescriber or pharmacist can weigh your baby's age and whether a better-studied alternative would do the same job. Worth asking before stopping a medicine you need.
