Nortriptyline

Because of the low levels of nortriptyline in breastmilk, amounts ingested by the infant are small and usually not been detected in the serum of the infant, although the less active metabolites are often detectable in low levels in infant serum. Immediate side effects have not been reported and a limited amount of follow-up has found no adverse effects on infant growth and development. A safety scoring system finds nortriptyline use to be possible with caution during breastfeeding.[1] Most authoritative reviewers consider nortriptyline one of the preferred antidepressants during breastfeeding.[2-4]
