Ciao. If you've been taking fiber and laxatives to treat your chronic constipation, there's something you need to know. Prescription Zelnorm is the first and only medicine approved to help relieve the multiple symptoms of chronic constipation. If you're constipated often, you deserve a medicine that works differently. Chronic constipation may mean you have a slow-moving digestive system, and only Zelnorm helps coordinate movement in your GI tract. Isn't it time to ask your doctor about Zelnorm? You should not take Zelnorm if you have a history of diarrhea, kidney, liver, or gallbladder disease, intestinal blockage, or adhesions. If you get new or worse abdominal pain, blood and stool, bad diarrhea, or diarrhea with cramping, fainting, or dizziness, stop taking Zelnorm and tell your doctor. Fiber and laxatives just didn't work for me, so I talked to my doctor about getting relief with Zelnorm. Isn't it time you asked your doctor about Zelnorm?
