Faq for ALOSETRON - ORAL

Alosetron is an oral medication used to treat irritable bowel syndrome with diarrhea (IBS-D) in women who have tried other treatments without success.

Alosetron works by blocking the action of serotonin in the intestines. Serotonin is a chemical that affects bowel movements and can contribute to the symptoms of IBS-D.

Common side effects of Alosetron may include constipation, stomach discomfort or pain, nausea, headache, and dizziness. It is important to discuss any side effects with your doctor.

Alosetron may take up to 4 weeks to start showing improvements in symptoms. It is important to continue taking the medication as prescribed by your doctor, even if you do not notice immediate relief.

Alosetron is currently only approved for use in women with IBS-D. It has not been studied or approved for use in men.

Alosetron is not recommended for use during pregnancy unless the potential benefits outweigh the risks. It is important to discuss the potential risks and benefits with your doctor if you are pregnant or planning to become pregnant.

Alosetron is not recommended for use in children under 18 years old. There is limited data available on the use of Alosetron in pediatric patients.

Certain medications may interact with Alosetron, including fluvoxamine, ciprofloxacin, erythromycin, and ketoconazole, among others. It is important to inform your doctor of all medications you are taking, including over-the-counter drugs and supplements.

Alosetron is typically used as a short-term treatment for IBS-D. The duration of treatment may vary depending on the individual's response and the advice of their doctor. Long-term use of Alosetron may carry an increased risk of serious side effects.


Warning

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.
