the Pharmacist, told me that we need to look at
dosage and which ones were equivalent to the RX I had....it worked
for a few more years then no longer helped me.
Anyway I got a new med from my Dr this one is a H2b instead of a PPI...and is working much better for me.....
As for the no heartburn, could be you have LPR also known as Silent Reflux bcuz not everyone has heartburn with it.
May I ask, have you had any PH testing?
....modify your diet and lifestyle?
