Drug Levels and Effects

Summary of Use during Lactation

Because of the lack of data on use during breastfeeding, other antidepressants are preferred during breastfeeding.

Maternal Levels. Relevant published information was not found as of the revision date.

Infant Levels. Relevant published information was not found as of the revision date.

Effects in Breastfed Infants

Effects on Lactation and Breastmilk

Phenelzine can elevate serum prolactin in some patients and has caused galactorrhea in nonpregnant, nonnursing patients.[1,2] The clinical relevance of these findings in nursing mothers is not known. The prolactin level in a mother with established lactation may not affect her ability to breastfeed.

Alternate Drugs to Consider

Nortriptyline, Paroxetine, Sertraline
