I am a 70-year-old female. I was diagnosed with Crohn's three years ago and am taking Pentasa. My condition is mild to moderate and relatively stable. I have taken Nexium for acid reflux all this time, with no bad effects. During my last visit, my doctor advised me to wean myself off of Nexium because it could worsen my Crohn's. Has anyone experienced a worsening of Crohn's symptoms while taking Nexium?
