An Overview of Medicines for Irritable Bowel Syndrome
Healthcare providers may choose to prescribe medications to help ease symptoms of
irritable bowel syndrome (IBS). Some different types of IBS medications include:
- Antispasmodics
- Laxatives
- Antidiarrheal medicines
- Antidepressants
- Antianxiety medications
- Drugs specifically approved to treat IBS.
The following sections explain in detail the various medications a healthcare provider may recommend when treating IBS symptoms.
Antispasmodics
Antispasmodic medications are used to decrease the abdominal (stomach) pain and cramping in your intestines. They are the most frequently prescribed medications for IBS. Examples include:
- Clidinium and chlordiazepoxide (Librax®), which includes both an antispasmodic and an antianxiety medication
- Dicyclomine (Bentyl®)
- Hyoscyamine (Levsin®, Anaspaz®)
- Hyoscyamine, atropine, scopolamine, and phenobarbital (Donnatal®).
These medicines appear to work best when taken before symptoms occur, so they are most helpful when a person can predict the beginning of symptoms.
