Breastfeeding and sertraline: a 24-hour analysis.

Abstract

These data indicate that sertraline levels in breast milk vary substantially over 24 hours and appear to be lowest within the 2 hours before and 1 hour after ingestion of the medication, with the peak probably occurring between Hours 1 and 9 postingestion. However, the absence of detectable serum sertraline and nortriptyline levels in the infant suggests that if either medication is present in infant serum, its concentration would be extremely low. No abnormal occurrences have been noted in the development of the infant. It would be important in future studies to measure metabolites in addition to medication levels since the former have been associated with untoward events in an infant.
