Is Cabergoline safe while breastfeeding?

Here is what NIH LactMed, the U.S. National Library of Medicine's authority on medicines and breastfeeding, reports about Cabergoline. This is a summary of that source — not our own verdict.

Effects on the breastfed infant

A woman with acromegaly was treated with lanreotide Autogel 120 mg monthly, cabergoline 2 mg weekly and pegvisomant 80 mg weekly. She breastfed (extent not stated) her infant and they were followed for 12 years. Her child had normal growth and development.[ 13 ]

Effects on milk supply

Seventeen women who did not wish to breastfeed received a placebo or a single oral dose of cabergoline 400 mcg or 600 mcg on day 2 or 3 postpartum. Use of other lactation suppressing measures (e.g., breast binding, lack of nipple stimulation) was not mentioned. Blood samples were taken periodically over the next 96 hours. In the 7 women who received 400 mcg, plasma prolactin levels were decreased at 24 and 48 hours, but 4 developed breast engorgement. In the 5 women who received 600 mcg, plasma prolactin levels were decreased by 12 hours and persisted up to 96 hours and none developed breast engorgement. Some women had minor decreases in blood pressure, but no other adverse effects were reported.[ 14 ] Thirty-two women who did not wish to breastfeed were given placebo or cabergoline 400, 600 or 800 mcg within 24 hours after delivery in a double-blind trial. Use of other lactation suppressing measures (e.g., breast binding, lack of nipple stimulation) was not mentioned. Lactation was prevented in 4 of 8 women who received the 400 mcg dose and all women who received the 600 or 800 mcg dose. Only 1 of 8 women receiving placebo had cessation of lactation by day 14 postpartum. Serum prolactin levels collected on days 2, 3 and 4 of treatment were decreased significantly in all women who received cabergoline, but the decreases were not statistically different among the various doses.[ 15 ] A prospective, randomized, double-blinded study compared the effects of a single dose of cabergoline 0.5, 0.75 or 1 mg in 40 women each and to 20 women who received a placebo. The drug was given in the first 24 hours postpartum and use of other lactation suppressing measures (e.g., breast binding, lack of nipple stimulation) was not mentioned. The adequacy of lactation suppression on day 14 postpartum was dose-related, with excellent results in 18 patients who receive 0.5 mg, 28 who received 0.75 mg and 36 who received 1 mg. Serum prolactin levels collected during 13 days of treatment we
