Practical guidance
According to the prescribing information for Pantoprazole, cognitive side effects are listed when documented. Practical steps include adjusting the dose timing (taking Protonix at 20mg, 40mg at bedtime if it sedates), ensuring adequate sleep, addressing untreated anxiety or low mood that mimics cognitive symptoms, and reviewing other medications that may add cognitive load. Persistent severe brain fog warrants prescriber review and consideration of alternatives.
