Answer by Dr. Ru: About CP 601B usage in lactation

CP 601B hormone reduces Prolactin serum levels and may likely inhibit milk production mainly soon after delivery. No significant increase of CP 601B serum levels neither in the mother´s milk nor in the infant’s serum have been found after administration to the mother. No adverse side effects have been noticed in the infant.

Answer by DrLact: About CP 601B usage in lactation

Limited data indicate that a low-dose (100 mg) subcutaneous CP 601B pellet given to a nursing mother appears not to increase milk CP 601B levels markedly. CP 601B has low oral bioavailability because of extensive first-pass metabolism, so it is unlikely to affect the breastfed infant. One breastfed infant seemed not to be adversely affected by low-dose maternal CP 601B therapy.

CP 601B Side Effects in Breastfeeding

An infant (age not stated) was breastfed (extent not stated) after implantation of 100 mg of CP 601B subcutaneously. No adverse effects were noted in the infant over a 5-month period.[1]

CP 601B Possible Effects in Breastfeeding

Supraphysiologic serum levels of CP 601B, either from a tumor[2][3] or from exogenously administered CP 601B,[4] reduces milk production in postpartum women. CP 601B alone reduces serum prolactin;[4] however, when given in combination with estrogen and progestin, serum prolactin levels are not markedly reduced.[5] CP 601B was previously used therapeutically to suppress lactation, usually in combination with an estrogen.[4][5][6][7][8][9][10]
