Because of its relatively extensive excretion into breastmilk and its renal excretion, other beta-adrenergic blocking drugs are preferred to nadolol, especially while nursing a newborn or preterm infant.

Relevant published information on nadolol 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 nadolol.[6]

Relevant published information on the effects of beta-blockade or nadolol 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.[7]
