Severe rhinorrhea and respiratory distress in a neonate exposed to fluphenazine hydrochloride prenatally

OBJECTIVE: To report a case of respiratory distress with severe rhinorrhea in a newborn exposed prenatally to fluphenazine hydrochloride. CASE SUMMARY: The safety of phenothiazines during pregnancy and the effect on the fetus and newborn are not well known. We describe a newborn who had severe rhinorrhea, vomiting, and respiratory distress after being exposed in utero to fluphenazine hydrochloride. Sepsis, choanal atresia, and congenital syphilis were excluded as causative factors for rhinorrhea. The rhinorrhea and upper airway obstruction responded to treatment with pseudoephedrine. CONCLUSIONS: Severe rhinorrhea, vomiting, and respiratory distress that occurred in this infant have not been reported previously following prenatal fluphenazine hydrochloride exposure. Awareness of this problem would be helpful to clinicians and should be considered in the differential diagnosis of rhinorrhea in newborns.
