Hi all. I was recently at ER 3 times and then admitted to hosp for severe abdominal pain. After many tests to rule out life threatening things and other GI issues beyond IBS, the working theory is a flare up of my IBS with constipation. Doc started me on Zelnorm. Anyone care to share their experiences with this med? How long did it take after you started it for you to get relief of pain etc.? How long till you had a BM? Was it helpful for you? Any side effects? I was too tired and uncomfortable at hospital yesterday to think to ask him some of this stuff and his nurse was of limited help today. He started me on 3mg twice a day x 2 weeks, then change to one whole 6mg pill a day. (He had done 2mg twice a day but drugstore didn't stock that dosage and I couldn't wait for them to order it and for it to arrive tomorrow or next day, so he changed it.) And of course, stop if diarrhea develops and call him then. I've had 2 doses of zelnorm (just took the second one) but no BM yet. Of course, with all this pain, I haven't eaten much either. Any info you care to share would be appreciated. Thanks so much.
