Irritable Bowel Syndrome Home > Bentyl and Pregnancy

In animal studies on Bentyl (dicyclomine) and pregnancy, the medication did not cause any problems when it was given to pregnant rabbits. Human studies also did not reveal any risks. If you are using Bentyl and pregnancy occurs, your healthcare provider will weigh the benefits and potential risks in your particular situation before making a recommendation.

An Introduction to Using Bentyl During Pregnancy

Bentyl® (dicyclomine hydrochloride) is a prescription medicine approved to treat irritable bowel syndrome (IBS). Animal studies suggest that Bentyl is probably safe for use in pregnant women.

Bentyl and Pregnancy Category B

The U.S. Food and Drug Administration (FDA) uses a category system to classify the possible risks to a fetus when a specific medicine is taken during pregnancy. Pregnancy Category B is given to medicines that have not been adequately studied in pregnant humans but that do not appear to cause harm to the fetus in animal studies.
When large doses of Bentyl were given to pregnant rabbits, no problems were seen. Also, experience with Bentyl in pregnant women has not revealed any risks. In fact, dicyclomine (the active ingredient in Bentyl) was used in a medication to treat nausea and vomiting during pregnancy many years ago (it has since been removed from the product when it was discovered that dicyclomine did not work for this use).
However, it is important to note that animals do not always respond to medicines the same way that humans do. Therefore, a pregnancy Category B medicine should be given to a pregnant woman only if a healthcare provider believes that the benefits to the woman outweigh any possible risks to the unborn child.

Final Thoughts on Bentyl and Pregnancy

If you are pregnant or are thinking about becoming pregnant, let your healthcare provider know. He or she will consider the benefits and risks of using Bentyl during pregnancy before making a recommendation in your particular situation.
