GERD
"I was prescribed this medication approximately 4 years ago. I experienced severe heartburn and reflux, so much so that I had to sleep with the head of my bed elevated. I filled the prescription but left it in the medicine cabinet for a year without taking one pill. A year after filling it I made a dental appointment because I noticed that the enamel on my teeth was flaking off. The dentist asked me if I had GERD. I said, yes and then he asked me if I was on anything for it. I told him no and he suggested I take something immediately. Turns out the GERD eroded the enamel off of 17 teeth and I had to have extensive dental work done, to the tune of $20K. Expensive lesson to learn but one learned nonetheless. No side effects whatsoever."
