For GERD "I started taking Protonix 40mg once daily after they took Zantac off the market. I started having a lot of stomach pain, gas, bloating, and watery diarrhea. It took me a while to figure out it was the Protonix. I stopped taking it and replaced it with Pepcid Complete once a day. Almost immediately those symptoms went away. I would be very careful taking this drug."

For GERD "Worked at first to bring heartburn/acid reflux under control, however I had to stop taking it because it started causing severe stomach & abdominal pain. Now control through diet & Tums EX. The pain from the Protonix side effect was terrible when it started happening."
