The FDA categorizes medications based on safety for use during pregnancy. Five categories - A, B, C, D, and X, are used to classify the possible risks to an unborn baby when a medication is taken during pregnancy.

Lubiprostone falls into category C. There are no good studies that have been done in humans with lubiprostone. In animals studies, pregnant animals were given this medication and had some babies born with problems. However, this medication may sometimes still help human mothers and their babies more than it might cause harm.

Women should have a negative pregnancy test before beginning treatment with lubiprostone and need to practice effective birth control measures.
