Fetal Risk Summary

Mesoridazine is a piperidyl phenothiazine. Phenothiazines readily cross the placenta (1). No specific information on its use in pregnancy has been located. Although occasional reports have attempted to link various phenothiazine compounds with congenital malformations, the bulk of the evidence indicates that these drugs are safe for the mother and fetus (see Chlorpromazine).

Breast Feeding Summary

No reports describing the excretion of mesoridazine into breast milk have been located. The American Academy of Pediatrics classifies mesoridazine as an agent whose effect on the nursing infant is unknown but may be of concern (2).
