I hope you are aware that in clinical trials for Zelnorm, IBS patients fared only a little better -- 5 percent to 11 percent better -- when taking it than when taking dummy pills (placebos).
The FDA has concluded that Zelnorm seems to work best during the first month of its use, before its effects wane after three months of treatment.
Side-effects of Zelnorm can be quite severe.........
headache
diarrhea
flatulence
nausea
fatigue
heartburn
hemorrhoids
painful menstruation
trouble sleeping
abdominal pain
back pain
chest pain
vomiting
Best to stick to a plant-based diet within Natural Hygiene as listed in my original post which has no side-effects and which is bio-compatible with no side effects.
