Thank you for your query. Although anti-spasmodic medication helps with the pain of irritable bowel syndrome, it is not good for chronic use. The reason being that irritable bowel is a problem with abnormal motility of the bowel at the root of the problem, taking a drug that paralyzes the smooth muscle stops the spasm, but disturbed the motility even further . You need a more holistic approach to your problem, something that will normalize motility, promote regular normal stools and normalize the bacteria in the bowel. Also speak to a dietician regarding the correct diet. I trust this information helps you.
