GERD
"I have had great results for several years with generic pantoprazole, except twice when the pharmacy used the version from Sun Pharma. Not sure the marked difference (although there was a patent lawsuit against Sun for not disclosing a slight difference in chemical structure several years ago), but taking the Sun version is pretty much like taking nothing at all. I took a week&#039;s worth this time (there is a shortage of the Teva drug I usually get) and spent last night sick to my stomach with gnawing pain and bizarre single hiccups and belches. And while the pharmacy apparently had gotten some of the Teva brand in, I had to pay the full $40 because I couldn&#039;t get another batch covered by insurance for 2 weeks. Not all generics are equal."
