Q. I have had intermittent heartburn for years. My doctor ordered an upper endoscopy to look at my esophagus and stomach. My esophagus is inflamed due to acid reflux. I was told to stay on prescription-strength pantoprazole indefinitely. But I worry about side effects. If I eat less acidic foods and don't experience heartburn, is it necessary to take this drug to keep my esophagus healthy?

A. Pantoprazole (Protonix) is a proton-pump inhibitor (PPI). Drugs in this class are the most potent acid inhibitors. Examples of other PPIs include esomeprazole (Nexium), lansoprazole (Prevacid), omeprazole (Prilosec), and rabeprazole (AcipHex).
