If anyone is taking the pill form of prometrium... the FDA deems it a pregnancy category B. (No proven problems attributed to the drug, take if benefit outweighs rist) Although they do not do studies in pregnant women, drs are required to keep track of people who take it, especially if there was a problem. The PI (every word is reviewed by the FDA) states that one woman had a child w/ a cleft pallet, but it could not be attributed to the drug. There are no more malformations of children when mothers take this drug, then with mothers who don't. I work for a large drug company, and understand these items are very stringently watched over. Hope this helps. I'm scared too.
