The Food and Drug Administration is warning consumers today that certain stomach acid drugs may increase the risk of a serious intestinal bacteria infection. The drugs, including Nexium, Prilosec, Prevacid, Zegerid and others, fall into a category called proton pump inhibitors (PPIs). They are prescribed to treat acid reflux, stomach ulcers and other conditions, and work by reducing the amount of acid in the stomach. The bacterial illness is called Clostridium difficile–associated diarrhea (CDAD), and its main symptom is diarrhea that does not improve, according to an FDA statement. The bacteria are commonly referred to as "C. diff."
