Dulcolax
"Dulcolax did me an injustice. I took 2 and after 11 hours I almost pass out with an excruciating abdominal pain associated with loose bowels. When the loose bowel had stopped for a few minutes, I had to lie on the floor because of the discomfort in my abdomen. Shortly after I had to rush again to the bathroom again and again with this horrific pain. I wish I didn't take this pill because its' side effect was too severe for me. I won't recommend it to anyone."
