I have seen my gasto consultant and he has given me this to try. I was wondering if anyone has tried it and if they work for constipation. I have heard the side effects can affect some people. I have tried Prucalopride and Linzess with limited success. They are not cheap as I have to pay privately for them, so would like some advice before I buy. I used to take Zelnorm before it was taken off the market and that worked well.
