Irritable Bowel Syndrome Health Center

Unfortunately, many people suffer from IBS for a long time before seeking medical treatment. Up to 70 percent of people suffering from IBS are not receiving medical care for their symptoms. No cure has been found for IBS, but many options are available to treat the symptoms.

The doctor will prescribe the best treatments for a person’s particular symptoms and encourage the person to manage stress and make dietary changes. Medications are an important part of relieving symptoms. The doctor may suggest fiber supplements or laxatives for constipation or medicines to decrease diarrhea, such as diphenoxylate and atropine (Lomotil) or loperamide (Imodium).

An antispasmodic is commonly prescribed, which helps control colon muscle spasms and reduce abdominal pain. Antidepressants may relieve some symptoms. However, both antispasmodics and antidepressants can worsen constipation, so some doctors will also prescribe medications that relax muscles in the bladder and intestines, such as belladonna alkaloid combinations and phenobarbital (Donnatal) and chlordiazepoxide and clidinium bromide (Librax). These medications contain a mild sedative, which can be habit forming, so they need to be used under the guidance of a physician.

A medication available specifically to treat IBS is alosetron hydrochloride (Lotronex). Lotronex has been reapproved with significant restrictions by the U.S. Food and Drug Administration (FDA) for women with severe IBS who have not responded to conventional therapy and whose primary symptom is diarrhea. However, even in these patients, Lotronex should be used with great caution because it can have serious side effects such as severe constipation or decreased blood flow to the colon. With any medication, even over–the–counter medications such as laxatives and fiber supplements, it is important to follow the doctor’s instructions. Some people report a worsening in abdominal bloating and gas from increased fiber intake, and laxatives can be habit forming if they are used too frequently.

Medications affect people differently, and no one medication or combination of medications will work for everyone with IBS. Working with the doctor to find the best combination of medicine, diet, counseling, and support to control symptoms may be helpful.
