Essential Information

1

Escalate for watery or bloody diarrhea—C. difficile has been reported with PPI use

Consider periodic magnesium and vitamin B12 checks for long-term therapy

3

Encourage lifestyle measures (small meals, avoiding triggers) to minimize prolonged reliance on PPIs

Clinical Overview

Like other PPIs, esomeprazole can alter mineral absorption and gut flora over time. Evaluate the ongoing need for acid suppression at each visit.
