It is very important that your doctor check your progress at regular visits. This will allow your doctor to see if the medicine is working properly and to decide if you should continue to take it.
Stop taking alosetron and check with your doctor right away if you become constipated or have symptoms of poor blood flow to your bowels (ischemic colitis). Some symptoms of poor blood flow are: new or worsening abdominal pain, bloody diarrhea, or blood in the stool.
Do not start taking alosetron again unless your doctor tells you to do so.
Do not take this medicine if you are also using fluvoxamine (Luvox®).
