Small, occasional doses of trans-1-(2-Pyridyl)-3-pyrrolidino-1-p-tolylprop-1-ene would not be expected to cause any adverse effects in breastfed infants. Larger doses or more prolonged use may cause effects in the infant or decrease the milk supply, particularly in combination with a sympathomimetic such as pseudoephedrine or before lactation is well established. The nonsedating antihistamines are preferred alternatives.

trans-1-(2-Pyridyl)-3-pyrrolidino-1-p-tolylprop-1-ene Side Effects in Breastfeeding

In one telephone follow-up study, mothers reported irritability and colicky symptoms 10% of infants exposed to various antihistamines and drowsiness was reported in 1.6% of infants. None of the reactions required medical attention and none of the mothers were taking trans-1-(2-Pyridyl)-3-pyrrolidino-1-p-tolylprop-1-ene.[2] In one study, no infant side effects were reported in three infants whose mothers took one dose of trans-1-(2-Pyridyl)-3-pyrrolidino-1-p-tolylprop-1-ene 2.5 mg and pseudoephedrine 60 mg.[1]

trans-1-(2-Pyridyl)-3-pyrrolidino-1-p-tolylprop-1-ene Possible Effects in Breastfeeding

Antihistamines in relatively high doses given by injection can decrease basal serum prolactin in nonlactating women and in early postpartum women.[3][4] However, suckling-induced prolactin secretion is not affected by antihistamine pretreatment of postpartum mothers.[3] Whether lower oral doses of antihistamines have the same effect on serum prolactin or whether the effects on prolactin have any consequences on breastfeeding success have not been studied. The prolactin level in a mother with established lactation may not affect her ability to breastfeed.
