As to the conflicting advice you recieved on long-term Nexium use, IT IS NOT benign over the long term
. Virgo57 is right about the Vitamin absorption problems long
can cause. Beyond that, prolonged use of PPIs can cause gastric cancer. I have been using them since 1989, non-stop, and in each of my last two semiannual endoscopies, gastric polyps were found and removed.
