IBS is a common disorder of the gut and can affect up to 1 in 5 people at some stage in their life.  Colofac and Fybogel mebeverine are prescription medications that help to reduce spasm and sooth the bowel.

Please read the important information below before ordering 

IBS symptoms vary from one person to another. The most common symptoms of IBS include abdominal pain, bloating and bouts of diarrhoea or constipation.

Irritable bowel syndrome symptoms tend to come and go. Symptoms may be present for few days at a time, or a week or longer. They usually settle down completely between flare-ups only to come back later. IBS is triggered in some people by stress. Some people can identify foods associated with a flare up of their symptoms. 

Causes of IBS

The cause of IBS remains unclear. IBS is a functional disorder which means there is a problem with the function of a part of the body, but there is no abnormality in the structure. Certain factors may play a role, and include overactivity of the nerves or muscles of the gut, intolerance to certain foods, previous gut infection (gastroenteritis) and stress or anxiety.

IBS should not be self-diagnosed as there are a number of more serious conditions which have similar symptoms to IBS and need to be ruled out before a diagnosis of IBS can be made.

IBS has certain recognisable features that help to confirm the diagnosis:

  • People usually have IBS on and off for years.
  • IBS usually starts in the 20-30s.
  • The pattern of symptoms of IBS are usually similar from one flare up to the next.
  • People with IBS are usually perfectly well and symptoms free between flare-ups.

Symptoms suggestive of a condition other than IBS: (You should report these symptoms to your GP or regular doctor urgently)

  • Weight loss (IBS does not usually cause weight loss)
  • Constant pain or increasing pain in one spot (the pain of IBS usually comes and goes during a flare up and disappears completely between flare ups)
  • Worsening constipation suggesting a blockage of the bowel
  • Blood in the stools. IBS can cause diarrhoea but blood in the stool should always be investigated by your GP
  • Symptoms starting in people over 50 (IBS usually starts early in life although it may be a life-long complaint)

If in doubt please see a GP and do not self-treat.

Treatments: Colofac, Fybogel

This service is for patients who have previously been diagnosed with IBS by their GP or doctor.

  • Colofac contains mebeverine, which is an antispasmodic.
  • Fybogel with colofac contains mebeverine plus fibre. For some people this works better than Colofac on its own.

Other things that may help in some people are: altering the amount of fibre in your diet, identifying and avoiding foods that seem to be associated with flare-ups, taking regular exercise and reducing stress or anxiety levels.

Side effects:

Significant side effects are rare. As with any medication, allergic reactions are possible. Please read the manufacturer's patient information leaflet for full details.
