Answer by Dr. Ru: About COL 1621 usage in lactation

COL 1621 hormone reduces Prolactin serum levels and may likely inhibit milk production mainly soon after delivery. No significant increase of COL 1621 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 COL 1621 usage in lactation

Limited data indicate that a low-dose (100 mg) subcutaneous COL 1621 pellet given to a nursing mother appears not to increase milk COL 1621 levels markedly. COL 1621 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 COL 1621 therapy.

COL 1621 Side Effects in Breastfeeding

An infant (age not stated) was breastfed (extent not stated) after implantation of 100 mg of COL 1621 subcutaneously. No adverse effects were noted in the infant over a 5-month period.[1]

COL 1621 Possible Effects in Breastfeeding

Supraphysiologic serum levels of COL 1621, either from a tumor[2][3] or from exogenously administered COL 1621,[4] reduces milk production in postpartum women. COL 1621 alone reduces serum prolactin;[4] however, when given in combination with estrogen and progestin, serum prolactin levels are not markedly reduced.[5] COL 1621 was previously used therapeutically to suppress lactation, usually in combination with an estrogen.[4][5][6][7][8][9][10]
