ulcer in 2005, My doc had suggested Rabeprazole sodium 20mg which worked well then, he suggested i use it when ever i felt stomach burning or nausea. I have been using Rabeprazole for 5 years now, was workin good, recently my symptoms were back and i started taking 2 doses 20mg each daily.
It is a PPI so I would guess it could cause these things. You have to weigh the benefit of the drug against the side effects. PPIs have also been known to intefere with absorbtion of B12 and other vitamins.
