Is HSDB 7472 Safe in Breastfeeding

I am a breastfeeding mother and i want to know if it is safe to use HSDB 7472? Is HSDB 7472 safe for nursing mother and child? Does HSDB 7472 extracts into breast milk? Does HSDB 7472 has any long term or short term side effects on infants? Can HSDB 7472 influence milk supply or can HSDB 7472 decrease milk supply in lactating mothers?

Isomer of zopiclone with similar hypnotic effects as benzodiazepines.Used for insomnia. At latest update no published data on excretion into breast milk were found. Zopiclone is excreted in milk in non-significant amount. Because the available published experience is poorer than with other drugs of the same group, it would be preferable an alternative and better known drug that would be considered safer, especially during the neonatal period and in case of prematurity.

Because no information is available on the use of HSDB 7472 during breastfeeding, an alternate hypnotic may be preferred, especially while nursing a newborn or preterm infant. Data from the racemate, zopiclone, in larger doses indicate that occasional use while breastfeeding an older infant should pose little risk to the infant, but the infant should be monitored for excessive drowsiness.[1]

In 12 mothers who were 2 to 6 days postpartum and took 7.5 mg of zopiclone, infant breastfeeding was interrupted for 8 to 10 hours before resuming. No unusual effect were noted in the infants.[1] Thirty-week preterm twins were born to a mother who took zopiclone 3.75 mg 4 times daily for tension headache during pregnancy. They developed withdrawal symptoms during the first week of life. Beginning at 2 weeks of age, they were about two-thirds breastfed by their mother who continued the drug at the same dose. The infants had no clinical abnormalities and were discharged from the hospital 6 weeks after birth.[4]
