I was on Protonix for awhile for acid reflux, then was switched to Nexium, which I still take. The Inderal, I think, is a beta blocker, which makes heartburn worse. So does aspirin. That's probably why you were given Protonix. I don't take a beta blocker nor do I use aspirin, Advil, or Aleve because they make reflux worse. I do take one other med that causes mild reflux, but I have to take that for the rest of my life. So, I take a low dose of Nexium.
