From the Guidelines

Protonix (pantoprazole) prophylaxis in the ICU should be discontinued once a patient tolerates enteral nutrition for 24-48 hours. After a patient has successfully transitioned to oral intake or enteral feeding, the risk of stress-related mucosal damage decreases significantly, making continued acid suppression unnecessary for most patients. This approach is supported by the principles outlined in the surviving sepsis campaign guidelines, which emphasize the importance of early enteral nutrition in critically ill patients [ 1 ]. When discontinuing, no tapering is required; the medication can be stopped directly. However, patients with other indications for acid suppression therapy (such as active gastrointestinal bleeding, history of peptic ulcer disease, or concurrent use of medications that increase bleeding risk like anticoagulants or steroids) may need to continue pantoprazole beyond ICU discharge. The rationale for discontinuation after establishing enteral nutrition is that food provides a natural buffering effect against gastric acid, and continued unnecessary use of proton pump inhibitors like pantoprazole is associated with increased risks of Clostridioides difficile infection, hospital-acquired pneumonia, and potential drug interactions [ 1 ].

Some key points to consider when managing protonix prophylaxis in the ICU include:

  • Early initiation of enteral feeding is recommended for critically ill patients with sepsis or septic shock who can be fed enterally [ 1 ]
  • The use of prokinetic agents and post-pyloric feeding tubes may be considered in patients with feeding intolerance [ 1 ]
  • Routine monitoring of gastric residual volumes is not recommended, but may be considered in patients with feeding intolerance or at high risk of aspiration [ 1 ]
  • Discontinuation of protonix prophylaxis after 24-48 hours of enteral nutrition tolerance can help minimize the risks associated with unnecessary acid suppression therapy.

It is essential to weigh the benefits and risks of continuing protonix prophylaxis on an individual basis, taking into account the patient's specific clinical circumstances and other indications for acid suppression therapy.
