A stupid OB at L+D the other day said that Zofran didnt cause constipation. I nearly smacked him. Anyway.
I have suffered from really bad constipation this pregnancy, and am here to cure your fears, I hope.
One, I was really worried about that whole fecal poisioning thing too!! I was scared I was killing my babies from the inside!!! My record for not "going" is 5 days. (applause)But my OB said that it needed to be in there way longer than that, and was usually only caused when there was an actual illness in your colon, that was not allowing to be dispelled since your body was not "releasing it". Yummy. (BTW- this is differnt OB from previously mentioned idiot, we can trust this one!
He ALSO said that nice little therpaies like milk of magnesia, and stuiff like that was not going to cure pregnancy or Zofran induced constipation. He prescribed me a stool softerner, not a laxative. Apparently its better to prevent than treat, because constipation can cause preterm labor, whcih is why I was in L+D, thinking I was in FULL transition labor at 23 weeks when in fact an enema solved the whole thing. How embarrassing is THAT!!!!! So now I am on that, and am having happy little toliet visits every night. Ahhhhh........
Point of my long rather gross story is to call OB and ask him for the big artillery, then you can stay on Zofran. And I am so sorry you are going thru this, I know how painful and icky it is.
Good Luck!!!!!
