Is (+-)-Pindolol Safe in Breastfeeding

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

Recommendation for Use During Lactation: Limited information indicates that maternal (+-)-Pindolol 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 (+-)-Pindolol 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 (+-)-Pindolol.[3]

Relevant published information on the effects of beta-blockade or (+-)-Pindolol 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]
