This website does not offer medical advice and has not been written or checked by doctors.
For many IBS sufferers drugs can be ineffective, but drug companies have now started to make drugs specifically for IBS symptoms, such as Lotronex and Zelnorm, and these have had more success.
Some of the older drugs available include anti-spasmodics, which are used to try to stop intestinal spasms and reduce pain, and anti-diarrheals such as Imodium. Anti-depressants can also be given to IBS sufferers in small doses to reduce pain.
I have labelled each medication as OTC (available over-the-counter) or prescription (only available through a doctor).
The medications are listed alphabetically in the menu on the left-hand side of the screen, and they are listed below by category. There is also a list of UK-specific medications.
