When I first started on
pantoprazole 6 or 8 years ago, it started working
for me from the first day. About a year ago I complained to my Doc that I was getting heartburn, etc, too often again, and he upped my dose to 2 pantoprazole per day, which barely improved things, hense the scope.
I've tried Tecta, which didn't seem to work for me, but I've never tried Prilosec nor Protonix (I don't think).
