Query: Be Careful Mucinex Causes Diarrhea

Be careful Mucinex can cause some serious DIARRHEA. I've taken a number of different drugs over the years that put out that disclaimer of side effects, "may cause diarrhea." However, in all my experiences no drug actually ever caused that problem for me... until now! I was suffering from a bad bronchitis and a co-worker suggested taking Mucinex. She put the bottle on my desk and said, "It works, you need it, so take it." I took one pill and WOW did it every work!! On my stomach and intestines! For the past 6 hours I've been running to the bathroom with liquid poop. Now that I've read some other reviews it's apparent that many others have had the same reaction. If you're taking Mucinex for it's EXPECTORANT effect please be prepared to EXPECT something else, DIARRHEA!
