constipation, drug induced
"Tried OTC and nothing worked.  This worked quickly for me and has now continued to work for 5 weeks.  Have read this board re side effects of others, but that has not been my experience.  Read the label and talk to your doc -- looks like overall the experience of bad side effects is rare for patients who try this med, but talk about it with your doc -- for me this has worked where nothing else did."
