Is Blocklin L Safe in Breastfeeding

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

Recommendation for Use During Lactation: Limited information indicates that maternal Blocklin L 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 Blocklin L 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 Blocklin L.[3]

Relevant published information on the effects of beta-blockade or Blocklin L 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]
