Congratulations on your pregnacy! Though I have had IC for 6 years, I didnt get d/xed until after I had my son, on May 8, 2001. So, I didnt take it when I was pregnant. I had to have a total hysterectomy 2 yrs ago, (due to severe endo), but prior to that, we were trying to concieve. My OB also treats my IC, and told me that I could take Elmiron while I was pregnant. He basically said the same thing as the previous poster.
Also, before I came here, I moderated an IC site with 30,000 members. We had several ladies who took it while pregnant, but we also had several who had been told they could not. So, I guess what I am trying to say is that I agree with the previous poster.....if you are going to be in a flare the whole time you are pregnant, than it sounds like the benefits outweigh the risks. After all, the stress and pain of the flares can stress the baby, just like the mother. So, I would take it. However, I would get more frequent liver panels taken during pregnancy, to make sure that things are going okay.
If you still have doubts, that poses significantly less risk to the baby, and that would be to learn to self cath and instill the Elmiron directly into your bladder. I know it sounds horrific, but it honestly is totally different than being cathed by someone else. In fact, I do this every day. I do rescue instills daily and open the Elmiron capsule and mix it with my Lidocaine, Sodium Bicarb, and put the meds in my bladder with a very small cath. The size is a 5 French. (It is about the diameter of a straw on a child's juice box.) I apply topical Lidocaine jelly before I cath to numb, and I also use it to lube the cath.
The advantage of doing that for you, would be the meds go directly into the bladder, bypassing the bloodstream, so very little (if any) would reach the baby. However, MORE of the Elmiron would make contact with your bladder so you would probobly feel better than ever!
You might ask your OB and URo about this option and see what they think.
If I can help you with anything at all, please let me know. I will be glad to answer any questions I can.
Again, congrats on your pregnancy!
