How does diet play a role in the symptoms of
IBS with diarrhea and bowel urgency?

Diet may be a factor for some…

  • Surveys show that 60% to 70% of IBS sufferers believe that certain foods in their diets are the cause of their symptoms
  • Examples of “trigger” foods may include citrus fruits, caffeinated drinks, alcoholic beverages, dairy products, and foods containing preservatives or additives

…but diet is not the only factor

  • Some studies show that “exclusion diets” (diets where you do not eat certain foods) are not always effective for everyone
  • If you find that cutting out certain foods still does not improve your symptoms, your IBS may be caused by other factors, such as too much serotonin in the gut

Helpful hint

Keeping a "food diary" may help you identify which foods to avoid. This may be a good first step after you have been told you have IBS with diarrhea.

Before using LOTRONEX® for the first time, you should:
  • Understand that LOTRONEX has serious risks for some people.
  • Read and follow the directions in the Medication Guide.
INDICATIONS AND USAGE

LOTRONEX is a medicine only for some women with severe irritable bowel syndrome (IBS) whose main problem is diarrhea; whose IBS symptoms have lasted 6 months or longer and have not been helped enough by other treatments.

You can tell if your IBS is severe if at least 1 of these is true: you have lots of painful stomach cramps or bloating; you often cannot control the need to have a bowel movement, or you have “accidents” where your underwear gets dirty from diarrhea or bowel movements; you cannot lead a normal home or work life because you need to be near a bathroom.

Enough testing has not been done to confirm if LOTRONEX works in men or children under 18.

IMPORTANT SAFETY INFORMATION

LOTRONEX can cause serious side effects:

Some patients have reported serious intestinal side effects while taking LOTRONEX. These include:

  • Serious complications of constipation
  • Reduced blood flow to the bowel (ischemic colitis)

These can happen suddenly and may lead to a hospital stay and, in rare cases, blood transfusions, surgery, and death.

Stop taking LOTRONEX and call your doctor right away if you have problems clearing your bowels (are constipated) or get new or worsening pain in your stomach area or blood in your stools. If your constipation does not get better after stopping LOTRONEX, call your doctor again. If you stopped taking LOTRONEX, do not start taking LOTRONEX again unless your doctor tells you to do so.

People who are older, who are weak from sickness, or who take other constipating medicines may be more likely to have serious complications of constipation with LOTRONEX.

Who should not take LOTRONEX?

Do not take LOTRONEX if any of these apply to you:

  • Your main IBS problem is constipation or you are constipated most of the time.
  • You have had a bad problem from constipation. If you are constipated now, do not start taking LOTRONEX.
  • You have had bad bowel blockages.
  • You have had blood flow problems to your bowels, such as ischemic colitis.
  • You have had blood clots.
  • You have had Crohn’s disease, sores in the colon (ulcerative colitis), swelling of a sac in the intestine (diverticulitis), or severe liver disease.
  • You do not understand the Medication Guide or are not willing to follow it.
  • You are taking a medicine called LUVOX® (fluvoxamine).
