Linzess is the only drug currently on the market that helps many people but has side effects for many as well. Renexxion has another drug in late stages in similar class and will not have the side effects. But still a year or two away from being available. So a better alternative is coming soon!

FYI - had to stop Linzess because now I have very soft stools, urgency and diarrhea, especially in the morning. My diet has not changed, except on really bad days, I eat mostly rice and crackers.
