Following chronic exposure to clomipramine taken by a mother during pregnancy at 25 mg/j, the infant showed neonatal inadaptation syndrome associated with hypotonicity and hypoventilation with no fatal consequences. Infant serum levels of clomipramine and its metabolite were undetectable by sensitive and specific liquid chromatography after 33 days of breastfeeding. However, a concentration of 55.1 μg/L of clomipramine was found in the breast milk. Breastfeeding can be continued but a clinical surveillance of the couple mother-infant is strongly recommended.
