I just wanted to say that I was on Imuran and Remicade for my entire pregnancy, and I have, and will continue to nurse my healthy baby.
I have been a patient at the Mayo clinic in Rochester, MN due to the severity of my disease. All of the doctors that I have seen there have said that pregnancy is fine with these two drugs and the benefits of nursing far out way the VERY small amount the baby could possibly get.
I also contacted the Research institute in Texas which is currently studying the effects of these drugs in pregnant woman taking them for Ruehmatiod arthritis. They were very helpful and answered all of my questions. Nothing worth noting has been found I was told. The only thing was a possible higher risk of pre-term labor, which could possibly be attributed to the disease not the medication. The research institute also called me after I delivered and asked me again if they could answer more questions.
I hope this info helps a little
