Long-acting benzodiazepine. Most of the clorazepate is metabolized to N-desmethyldiazepam (nordiazepam) which is the active metabolite of diazepam. It is excreted in breast milk in clinically insignificant amounts (Rey 1979). Sedation has been observed in infants whose mothers were taking diazepam (Wesson 1985). Due to the lack of publications on this subject, until more information is known about this drug in relation to breastfeeding, safer known alternatives are preferred, especially in the neonatal period and in case of prematurity (McElhatton 1994). Occasional and low-dose use of benzodiazepines is compatible with breastfeeding. It is advisable to choose short-duration benzodiazepines and to use the minimum effective dose. Monitor drowsiness and the adequate feeding of the infant (Kanto 1982). It is not recommended to co-sleep with the baby if you are taking this medication (UNICEF 2013, Landa 2012, ABM 2008, UNICEF 2006).
