I didn't have very good luck with this however if you click on the "green" Librax and scroll down you can see many reviews from other DS users.

Hey there,
I tried it for a while, myself. My GP and Gastro told me that it works for less than half that try it. It's worth trying though. The thing about it is anticholinergic/spasmolytic to prevent spasms in the colon and antianxiety medication as well (Librium). The benzo half of the drug does more than the spasmolytic, so it really helps those that suffer from stress related IBS. I have IBS-D, that does indeed get worse with stress, but is not primarily triggered by stress. So, I find that Librax works, but not necessarily much at all when I'm in an otherwise relaxed mood. So, you might have more success with it on a stressful day at work or while taking an exam than on a peaceful sunday.
I find that Pariet/Aciphex works better for the ability to eat a wider range of food than might otherwise upset my bowels. Spicy foods mainly, but I still can't over do it. I currently take Pariet about 3 or 4 times a week, just once a day and only 10mg (regular dose is 20mg a day). So I stay light on anything I take and only take as needed.

I do feel that if you find Librax works, you might find it's better to take on high stress/demand days when that might cause some pain.

I personally like it. It's not for everyday use, for me. But if you find you feel the same way after trying it, maybe ask about Aciphex. It's a PPI and I find a 10mg dose really helps keep the acidity of tomatoes and spices down so I can eat something yummy once in a while. But during boughts of pain, Librax and a boring diet of rice and tofu really seem to help me out.

It didn't work for me. Gave me a banging headache and horrible lower back pain in the middle of the night. It also slowed down my motility to where I had trouble going - which was quite a change from diarrhea. It was also very expensive. My doctor was insistent it was the cure all and when I stopped taking it he had to alternative treatment or suggestions. The other posts here are good, AdrianN has some good advice. Hope you are feeling better.

i told my doc about this med and he had no clue as to what it was for i

Librax saved me. I work in a corporate environment and I would have to take extra clothes to work with me every day due to the effects of IBS. Librax is the best. I took this med for about 3 months and the IBS symptoms went away within one week. Previously I had terrible IBS for about 3 months, pass the word on LIBRAX

i've use belladonna .it works for me..Nick...
