Gen. MedInfo


In 2007, tegaserod was removed from the U.S. market and was made available only through a restricted distribution program from the manufacturer. Beginning in April 2008, tegaserod will no longer be available through the restricted distribution program; therefore, the U.S. Food and Drug Administration (FDA) has decided to make tegaserod available to physicians for patients in emergency situations that are life-threatening or require hospitalization. If your doctor believes that you should receive tegaserod, he or she may contact the FDA for more information. If you are receiving tegaserod through the restricted distribution program, you should talk to your doctor about switching to another treatment.

Why is Tegaserod prescribed?

Tegaserod is used to relieve pain, bloating, and constipation caused by irritable bowel syndrome (IBS; a condition that causes stomach pain, bloating, constipation, and diarrhea) in women whose main symptom is constipation. Tegaserod is also used to increase the frequency of bowel movements and relieve bloating, straining, and stomach pain in women and men with chronic idiopathic constipation (constipation that is not due to other diseases or medications and that has been a problem for longer than 6 months). Tegaserod is in a class of medications called serotonin agonists. It works by improving muscle movement and increasing production of fluid in the bowels.

How should Tegaserod be used?

Tegaserod comes as a tablet to take by mouth. It is usually taken twice a day on an empty stomach shortly before a meal. Take tegaserod at around the same times every day. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take tegaserod exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.

If you have IBS with constipation, your doctor will probably tell you to take tegaserod for 4-6 weeks. If your symptoms improve, your doctor may tell you to take tegaserod for another 4-6 weeks. If you have chronic idiopathic constipation, you should talk to your doctor regularly to see if you should continue to take tegaserod. Be sure to tell your doctor how you are feeling, and do not take tegaserod for longer than your doctor prescribes.

Tegaserod controls the symptoms of irritable bowel syndrome and chronic idiopathic constipation, but does not cure these conditions. Continue to take tegaserod even if you feel well. Do not stop taking tegaserod without talking to your doctor. If you stop taking tegaserod, your symptoms may return within 1-2 weeks.

What special precautions to follow?

Before taking tegaserod,

  • tell your Doctor if you are allergic to tegaserod or any other medications.
  • tell your Doctor what other prescription and nonprescription medications, vitamins, herbal products, or nutritional supplements you are taking. Your doctor may need to adjust the dose of your medications or monitor you more carefully for side effects.
  • tell your doctor if you have diarrhea now or if you often have diarrhea; if you have or have ever had gallbladder, kidney, or liver disease; a blockage in your intestines or unexplained stomach pain; abdominal surgery (surgery on the area between your chest and hips); jaundice (yellowing of the skin or eyes); sphincter of Oddi dysfunction (blockage of bile or digestive juices flowing into the intestine that causes pain and/or jaundice); or ischemic colitis (decreased blood flow to the intestines causing rectal bleeding, bloody diarrhea, or stomach pain).
  • tell your doctor if you are pregnant, plan to become pregnant, or are breast-feeding. If you become pregnant while taking tegaserod, call your doctor. Do not breast-feed while you are taking tegaserod.
  • you may have some diarrhea, especially during your first week of taking tegaserod. However, if you have a lot of diarrhea, or if you also have severe cramping, dizziness, light-headedness, fainting, blurred vision, upset stomach or a fast heartbeat, you should stop taking tegaserod and call your doctor immediately.

What side effects can Tegaserod cause?

Tegaserod may cause side effects. Tell your doctor if any of these symptoms are severe or do not go away:

  • headache
  • diarrhea
  • nausea
  • vomiting
  • gas
  • leg or back pain
  • joint pain or problems
  • difficulty falling asleep or staying asleep
  • runny nose, congestion, or other cold symptoms
  • rash
  • hives
  • itching
  • swelling of the face, throat, tongue, lips, or eyes
  • difficulty breathing and swallowing
  • hoarseness

Some side effects can be serious. If you experience any of the following symptoms Consult your doctor immediately:

People with IBS may need to have abdominal surgery, especially gallbladder surgery, more often than people who do not have IBS. People with IBS who took tegaserod needed this type of surgery somewhat more often than people who did not take tegaserod. It is not known if taking tegaserod increases your chance of needing abdominal surgery. Talk to your doctor about the risk of taking Tegaserod.

You should know that tegaserod rarely may cause ischemic colitis. Tell your doctor and stop taking tegaserod right away if you have new or worsening stomach pain, bloody diarrhea, rectal bleeding, or blood in your stools.

Tegaserod may cause other side effects. Consult your doctor if you have any unusual problems while taking Tegaserod.
