Boots IBS Symptom Relief Tablets contain the active ingredient mebeverine hydrochloride. This belongs to a group of medicines called antispasmodics.
This medicine is used to treat symptoms of irritable bowel syndrome (IBS). This is a very common condition which causes spasm and pain in the gut or intestine.
The intestine is a long muscular tube which food passes down so it can be digested. If the intestine goes into spasm and squeezes too tightly, you get pain. The way this medicine works is by relieving the spasm and pain.
The main symptoms of irritable bowel syndrome (IBS) include:
These symptoms may vary from person to person.
Talk to your doctor if you develop new symptoms or if these symptoms continue for more than 14 days.
How you restrict your diet depends on the way IBS affects you. If you find that certain things bring on the symptoms, then it makes sense not to eat them. A high fibre diet may help, but ask your pharmacist for more information.
Some people find that learning to relax can help to lessen their symptoms of IBS. You may find it helpful to set aside a few moments each day to relax and gently unwind.
If any of the above applies to you, do not take this medicine and talk to your doctor or pharmacist
