WHAT IS IBS-C

SYMPTOMS & POSSIBLE CAUSES OF IBS-C

IBS-C IS A CHRONIC MEDICAL CONDITION

If you’re suffering from constipation with abdominal (belly) symptoms that return again and again, you may have a type of chronic constipation called Irritable Bowel Syndrome with Constipation (IBS-C).

WHAT ARE THE SYMPTOMS OF IBS-C?

IBS-C patients typically experience constipation with abdominal (belly) symptoms.

WHAT COULD SMALL, HARD STOOLS MEAN?  

The Bristol Stool Form Scale makes it easier to understand and talk about stools. The scale helps assess how long stools have been in the bowel by assigning them a number based on their size, shape, and consistency.

Type 1 stools have spent the most time in the bowel; type 7 have spent the least. Stools resembling types 1-2 may indicate constipation, types 3-5 are typically considered normal bowel movements, and types 6-7 could mean diarrhea.

WHAT CAUSES IBS-C?

The cause of IBS-C is unknown, but researchers believe several factors may contribute to the condition.

FLUID ABSORPTION

The colon may be absorbing too much fluid from stools, or the muscles in the colon may be moving too slowly. This can cause stools to become dry, hard, and difficult to pass.

NERVE SENSITIVITY

The nerves in the intestines may be extra sensitive, causing sufferers to feel more belly pain or discomfort than those who do not have IBS-C.

OVER 3 MILLION PATIENTS HAVE BEEN PRESCRIBED LINZESS*

LINZESS is a once-daily prescription treatment for adults with Irritable Bowel Syndrome with Constipation (IBS-C) or Chronic Idiopathic Constipation (CIC). It helps you have more frequent and complete bowel movements and helps relieve belly pain and overall abdominal symptoms** (pain, discomfort, and bloating) associated with IBS-C.

IMPORTANT RISK INFORMATION

  • Do not give LINZESS to children who are less than 2 years of age. It may harm them. LINZESS can cause severe diarrhea and your child could get severe dehydration (loss of a large amount of body water and salt).
  • Do not take LINZESS if a doctor has told you that you have a bowel blockage (intestinal obstruction).

Before you take LINZESS, tell your doctor about your medical conditions, including if you are:

  • Pregnant or plan to become pregnant. It is not known if LINZESS will harm your unborn baby.
  • Breastfeeding or plan to breastfeed. You and your doctor should decide if you will take LINZESS and breastfeed.

Tell your doctor about all the medicines you take, including prescription and over-the-counter medicines, vitamins, and herbal supplements.

Side Effects

LINZESS can cause serious side effects, including diarrhea, the most common side effect, which can sometimes be severe. Diarrhea often begins within the first 2 weeks of LINZESS treatment. Stop taking LINZESS and call your doctor right away if you get severe diarrhea during treatment with LINZESS.

Other common side effects of LINZESS include gas, stomach-area (abdominal) pain, swelling, or a feeling of fullness or pressure in your abdomen (distension). Call your doctor or go to the nearest hospital emergency room right away if you develop unusual or severe stomach-area (abdominal) pain, especially if you also have bright red, bloody stools or black stools that look like tar.

These are not all the possible side effects of LINZESS. For more information, ask your doctor or pharmacist.

What is LINZESS?

LINZESS® (linaclotide) is a prescription medication used in adults to treat irritable bowel syndrome with constipation (IBS‑C) and chronic idiopathic constipation (CIC). "Idiopathic" means the cause of the constipation is unknown. It is not known if LINZESS is safe and effective in children less than 18 years of age.
