Continuing to take an OTC proton pump inhibitor like Prilosec or Nexxium could be okay as long as someone has the blessing of their doctor. The directions on Prevacid are strongly worded, so I think it's less likely a doctor would suggest prolonged use.

One benefit to switching to a prescription med like Protonix is that it is covered by insurance and would cost a lot less than the OTC meds. It also sounds like BF is still suffering from GI symptoms despite being on Nexxium, so maybe he could benefit from a med change. IDK.

BF, I think it's a good idea to talk to your PCP about it no matter which direction you want to go in. Your doctor can give you the best guidance.
