I was diagnosed with IC. And Bladder Manager was recommended to me by my holistic doctor. I gave it a try and found that it does help. Now, in saying that....if I eat or drink something that is irritating to me, I may feel some IC....but it's not as strong as if I didn't take it. I recommend trying it out and seeing if it works for you. It has not irritated my stomach and I haven't noticed any side effects (like I have from IC medications).
