Although Remicade is classified as a Class B drug - my GI personally does not recommend it during pregnancy. If it such that without it you will not be healthy enough for pregnancy - then he would ok it - (and has as I have seen pregnant patients getting Remicade in his office) but it is not his first choice. (He hasn't let me conceive while on it.) His reasoning is that Remicade is still extremely new and he would much prefer to work with meds that he has years of experience with. He actually prefers Imuran to Remicade. Go figure!
