I looked in my nursing drug book...they tend to print a lot of info we do not see on the bottles and on the internet.
The biggies were:
GI Bleed, abdominal pain, diarrhea, stomatitis, agitation, anxiety and confusion. Do not use with history of ulcer disease or active GI bleed.
I think you're thinking right! Question the Dr's order. Did he give you like a prevacid or prilosec to take with it? If doubtful, I would definitely hold off until you know HE KNOWS about your problem! It might just have been overlooked.
I wish you relief soon!
Let us know what came about with this!
