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 "Started taking this about 8 years ago after developing an ulcer from taking Aleve. Was fine for a few years, with only flatulence and loose bowel movements. For the last 3 years, I started developing asthma symptoms (phlegm in throat and lungs, coughing). Stopping Protonix cleared it up. Took 1 pill again and the asthma started again. Too bad, I really liked this medication."

For GERD "Awful! Ruined an entire ten-day vacation. Gas, stomach cramps, headache, alternating constipation and diarrhea. I had started taking a few days before the vacation and did not think much about it. I thought I had a stomach bug as it started just a few days into the vacation. On day ten, I realized it might be this med. I stopped, and within two days everything went back to normal."
