Answer

Answer

There is conflicting evidence as to the safety of using PPIs and H2 blockers. [87, 88, 89, 90] Some studies have concluded that PPI use increases the risk of pneumonia or even the risk of multidrug-resistant pathogens causing pneumonia. Other, more recent, studies find such links may have been resulted from confounding factors. [91, 89]

PPIs were associated with an increased risk of C difficile colitis compared with H2 blockers. [92]
