I posted last week looking for information regarding taking progesterone or clomid while breastfeeding. I've received one response with information from Dr. Hale's book, the third edition (not the fourth). This is what he had to say about Clomid: "Clomid (clomiphene) Anti-estrogenic agent. May suppress lactation. Contraindicated in breast-feeding mothers." Thanks to Judy Dunlap for this information. The question here now is, does this mean that decreased milk supply is the only problem? It does not mention an effect on the nursing child. I'm still looking for information on Progesterone. The mother will be taking Micronised Progesterone, 100mg. 4 times a day, orally. If you can provide any information on this, please e-mail me in addition to the list. I am back to receiving mail but do not want to miss anything on this. I will also provide an update for all of you. Thanks, Teresa Smith, LLLL <[log in to unmask]>
