Hi...just noticed you posted in a different place the same question...just posting my response here also..
I had a similar pain management issue during pregnancy, and after learning the facts about what this drug could do to the baby and even me, I decided to tough it out and go cold turkey...no pain meds until my c-section when I had a saddle block.
What happened to me was I fell down two flights of steps and broke my pelvis in a couple of places, right in the middle of my pregnancy. I was told that there was nothing they could do for a broken pelvis...you can't set this in a cast. The only thing they could do was give me similar drugs you have been prescribed for pain management until the scheduled c-section (couldn't deliver vaginally because of the broken pelvis).
The pain was excruciating. I had already delivered one child, and I can tell you the pain from the broken pelvis superceded the pain of childbirth!! I was bedridden for many months and when I needed to move or walk it hurt so bad I'd vomit or almost black out. I couldn't function. But I also was able to stay home during pregnancy..so while I was miserable, I didn't have to worry about going to work or other obligations.
I was very tempted to take the pain killers, but learned that while there have been no formal studies on the effects of this drug on fetuses, it has been observed that not only was there a risk the baby would be born addicted, but some theorize the baby may be more likely to acquire a lifelong predisposition toward addiction that goes beyond withdrawl and addiction at birth!
I also learned that as with any drug use during pregnancy, there was a risk of possible complications for the baby such as breathing problems immediately after delivery, and in some reports, babies born addicted have been observed as having adverse behavioral problems.
If you are going to breastfeed the baby, the effects of the drug are intensified including suppressed breathing and related complications.
This drug also has abortive properties which means it may cause miscarriage, especially if combined with aspirin, which is common in pain management, the combined use can cause bleeding and complications for both mother and child during delivery.
I know when you suffer with serious pain it's a tough call, but in the big picture there is too much at stake for your little one. Especially since even the medical industry warns that while no formal studies have been done on its effects on fetuses, the drug is indeed considered unsafe for the unborn and should only be used in extreme circumstances under careful guidance of a physician.
I decided it wasn't worth it. I truly almost lost my mind a few times, but when it came time to deliver, and the baby was born perfectly healthy and I was finally able to take something for my pain, I felt it was well worth the sacrifice. And I do it all over again knowing that it would mean a delivery with no complications, and a safe and perfectly healthy baby.
Here are some of the sources I used to present my findings about this drug and pregnancy. The sites are very long and detailed, alot to go through, if you don't find what you're looking for, I just did a general search on yahoo for "hyrocondone and effects on fetus, and hydrocondone and pregnancy" oxycondone comes up for these searches, probably because these are in the same family of drugs;
