At usual doses, this drug is considered compatible with breastfeeding
The major drawback of chloral hydrate is the long half-life of its active metabolite, trichloroethanol, which could influence the baby if the mother takes the drug repeatedly. This derivative of chloral hydrate has been detected in the blood of infants up to 21 hours after its administration to the mother. Therefore, for prolonged use as hypnotic, is preferable to use other drugs with less risk of accumulation.
In most published cases have not been detected changes in infants, although there are reports of excessive sedation or restlessness during sleep, attributed to this drug.
Warning of the manufacturer:
Manufacturer says: Do not take if you are pregnant.
