Fybogel Mebeverine is a granule medication that contains two ingredients, mebeverine, and psyllium husks. While the mebeverine helps to treat abdominal cramps, the husks are designed to support the movement of waste in the bowels. Used together, these two substances can be helpful at reducing the symptoms associated with constipation.  

What is Fybogel Mebeverine? 

Fybogel Mebeverine is a fruit-flavored granule medication that contains the active ingredients psyllium husks and Mebevrine. Psyllium husks are a kind of plant-based fibre. They’re used to address the issue of constipation, and support people in maintaining normal bowel function when they suffer from various bowel disorders.  

When it comes into contact with fluid in the gut, Fybogel Mebeverine swells, which helps to increase the volume of faeces. The medication is not absorbed fully into the body. Increased volume in the bowel can help to stimulate the muscles of the intestines, which encourages them to move waste along and relieve constipation. However, it can take a while of taking this mediation before you will begin to notice any results.  

While the plant fibers in this substance increase the bulk of your waste, the Mebeverine is suitable for relaxing the muscles and walls of the intestines. This means that you won’t get the cramps associated with constipation. You may also find that the antispasmodic medication in Fybogel Mebeverine helps to reduce symptoms like wind and bloating, as well as diarrhea that alternates with periods of constipation. 

When is Fybogel Mebeverine used? 

Fybogel Mebeverine is a common and well-tolerated treatment for constipation that can be prescribed by a doctor or consultant. It is given to help treat constipation and the various symptoms that are associated with an inability to evacuate the bowels, including stomach pains, cramping and bloating.  

Fybogel Mebeverine is available in both a fruit flavored and plain version, which can be mixed with water to create a fibre-rich drink. The two active ingredients in Fybogel Mebeverine work together to soften your feces and reduce cramps. Additionally, some doctors and consultants will prescribe Fybogel Mebeverine to help keep the bowel movements of people with certain chronic conditions healthy. For instance, you may be given Fybogel Mebeverine if you have irritable bowel system. People with IBS or irritable bowel usually have trouble with diarrhea and constipation, as well as flatulence and abdominal cramping.
