Is MK 141 Safe in Breastfeeding

I am a breastfeeding mother and i want to know if it is safe to use MK 141? Is MK 141 safe for nursing mother and child? Does MK 141 extracts into breast milk? Does MK 141 has any long term or short term side effects on infants? Can MK 141 influence milk supply or can MK 141 decrease milk supply in lactating mothers?

Unless it is intentionally being used to lower maternal serum prolactin levels, MK 141 should be avoided during lactation because it may interfere with lactation, particularly in combination with a sympathomimetic such as pseudoephedrine or before lactation is well established. The nonsedating antihistamines are preferred alternatives.

Relevant published information on MK 141 was not found as of the revision date. In one telephone follow-up study, mothers reported irritability and colicky symptoms in 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 infants were exposed to MK 141.[1]

MK 141 16 to 24 mg daily lowers serum prolactin in the treatment of amenorrhea-galactorrhea syndrome because of its antiserotonin activity.[2] Additionally, 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 MK 141 have the same effect on serum prolactin or whether the effects on prolactin have any consequences on breastfeeding success have not been studied. It is possible that these effects would interfere with initiation of lactation, but the prolactin level in a mother with established lactation may not affect her ability to breastfeed.
