I'm not really taking any IBS medication per se. My doctor prescribed omeprazole which I do take and did not stop taking while I was taking Emma. For me, and my IBS situation may be worse, more irritated, but Emma didn't do all it said it would do or claimed it could do. I did find some relief with more productive flatulation. Trying to say that nicely. Other than that, no. Now the IBS clear I've not taken long enough. It's another all natural supplement like Emma that also has psyllium fiber in it.
