Breastfeeding: Short-term or occasional use of chloral hydrate during breastfeeding is unlikely to adversely affect the breastfed infant, especially if the infant is older than 2 months. Other sedative-hypnotics are preferred for long-term use during breastfeeding, especially while nursing a neonate or preterm infant. This information is based upon LactMed database (available at http://toxnet.nlm.nih.gov/cgi-bin/sis/htmlgen?LACT last accessed 21 June 2011). Due to the potential for serious adverse reactions in nursing infants, manufacturer recommends discontinuation of nursing or discontinuation of drug, taking into account the importance of the drug to the mother.
