Animal studies have shown evidence of retarded or impaired skeletal formation, and impaired viability and weight gain. There are no controlled data in human pregnancy.

Benzodiazepines cross the placenta and may cause hypotonia, respiratory depression, and hypothermia in the newborn infant. Withdrawal symptoms in newborn infants have been reported with this class of drug. Also, neonatal flaccidity has been reported in an infant born of a mother who had been receiving benzodiazepines.

To monitor the outcomes of pregnant women exposed to this drug, a National Pregnancy Registry for Other Psychiatric Medications has been established. Physicians are encouraged to register patients and pregnant women are encouraged to register themselves.

Triazolam Breastfeeding Warnings

A decision should be made to discontinue breastfeeding or discontinue the drug, taking into account the importance of the drug to the mother.

Excreted into human milk: Unknown
Excreted into animal milk: Yes

Comments:
-Some authorities state that use should be avoided.
-The American Academy of Pediatrics considers similarly acting drugs agents that may be of concern during breastfeeding.

Little information is available on the use of this drug during breastfeeding; an alternate short-acting hypnotic may be preferred (e.g., oxazepam or lorazepam), particularly when nursing a newborn or preterm infant. Because of its relatively short half-life, occasional use during breastfeeding in an older infant should pose little risk; however, the infant should be monitored for excessive drowsiness.
