Is HSDB 6539 Safe in Breastfeeding

I am a breastfeeding mother and i want to know if it is safe to use HSDB 6539? Is HSDB 6539 safe for nursing mother and child? Does HSDB 6539 extracts into breast milk? Does HSDB 6539 has any long term or short term side effects on infants? Can HSDB 6539 influence milk supply or can HSDB 6539 decrease milk supply in lactating mothers?

Recommendation for Use During Lactation: Limited information indicates that maternal HSDB 6539 produces low levels in milk. It also has a short half-life and only moderate renal excretion, so it would not be expected to cause any adverse effects in breastfed infants, especially if the infant is older than 2 months.

Relevant published information on HSDB 6539 was not found as of the revision date. A study of mothers taking beta-blockers during nursing found a numerically, but not statistically significant increased number of adverse reactions in those taking any beta-blocker. Although the ages of infants were matched to control infants, the ages of the affected infants were not stated. None of the mothers were taking HSDB 6539.[3]

Relevant published information on the effects of beta-blockade or HSDB 6539 during normal lactation was not found as of the revision date. A study in 6 patients with hyperprolactinemia and galactorrhea found no changes in serum prolactin levels following beta-adrenergic blockade with propranolol.[4]
