Drug

Alosetron

Pronounced

"a-LOE-se-tron"

Uses

Alosetron is used to treat women with severe irritable bowel syndrome (IBS) who have diarrhea as the main problem. It is not a cure, but it may help to decrease abdominal pain, sudden urges to have a bowel movement, and diarrhea.

This medication is not recommended for use by children because of the serious side effects that have been seen in adults.

Warning

Alosetron has rarely caused serious, sometimes fatal side effects of the intestines. These effects include reduced blood flow to the large intestine (ischemic colitis) and serious complications of constipation. If you have constipation, new or worsening stomach/abdominal pain, or bloody diarrhea/stools, stop taking this medication and get medical help right away. If your constipation does not go away after stopping alosetron, again tell your doctor right away. Do not take this medication again unless your doctors tells you to do so.

This medication should only be used by women with severe irritable bowel syndrome (IBS) whose main problem is diarrhea. Only carefully selected patients may use this medication. Consult your doctor or pharmacist for more information about the risks and benefits of using alosetron.

How to Use This Medication

Read the Medication Guide provided by your pharmacist before you start taking alosetron and each time you get a refill. If you have any questions, ask your doctor or pharmacist.

Take this medication by mouth with or without food as directed by your doctor, usually once or twice daily. The dosage is based on your medical condition and response to treatment. Do not start taking this medication if you are constipated.
