Trimipramine Levels and Effects while Breastfeeding
Summary of Use during Lactation
If trimipramine is required by the mother, it is not a reason to discontinue breastfeeding. Because of the lack of data on use during breastfeeding, other antidepressants are preferred during breastfeeding, especially while nursing a newborn or preterm infant.

Effects in Breastfed Infants
Published information on trimipramine was not found as of the revision date. Follow-up for 1 to 3 years in a group of 20 breastfed infants whose mothers were taking a tricyclic antidepressant found no adverse effects on growth and development. Two small controlled studies indicate that other tricyclic antidepressants have no adverse effect on infant development. In another study, 25 infants whose mothers took a tricyclic antidepressant during pregnancy and lactation were tested formally between 15 to 71 months and found to have normal growth and development. However, none of the mothers in any of these studies took trimipramine.
Effects on Lactation and Breastmilk
Trimipramine increases serum prolactin levels and has caused at least one case of galactorrhea. The maternal prolactin level in a mother with established lactation may not affect her ability to breastfeed.
An observational study looked at outcomes of 2859 women who took an antidepressant during the 2 years prior to pregnancy. Compared to women who did not take an antidepressant during pregnancy, mothers who took an antidepressant during all 3 trimesters of pregnancy were 30% less likely to be breastfeeding upon hospital discharge. Mothers who took an antidepressant only during the third trimester were 75% less likely to be breastfeeding at discharge. Those who took an antidepressant only during the first and second trimesters did not have a reduced likelihood of breastfeeding at discharge. The antidepressants used by the mothers were not specified.
