How long should Protonix (pantoprazole) be continued in a patient with a gastrointestinal (GI) bleed on Eliquis (apixaban) for pulmonary embolism (PE)?

Duration of Proton Pump Inhibitor Therapy After GI Bleed in a Patient on Eliquis for PE

For a patient with GI bleeding on Eliquis (apixaban) for pulmonary embolism, continue Protonix (pantoprazole) indefinitely for as long as anticoagulation therapy continues, which in the case of unprovoked PE should be lifelong. 1, 2

Immediate Management Context

When GI bleeding occurs in a patient on anticoagulation:

• Temporarily interrupt the DOAC (Eliquis) at presentation with GI bleeding 2, 3
• Initiate high-dose PPI therapy immediately for all patients with GI bleeding on antithrombotic therapy 2
• Do not administer prothrombin complex concentrate (PCC) or reversal agents for patients on DOACs during acute GI bleeding 3

Timing of Anticoagulation Resumption

After achieving hemostasis:

• Resume Eliquis within a maximum of 7 days after bleeding has stopped 2
• The American Society of Hematology recommends resumption of oral anticoagulation within 90 days for patients who survive major bleeding and require long-term anticoagulation 1
• Resuming anticoagulation after GI bleeding reduces all-cause mortality (RR 0.62) and thromboembolism risk (RR 0.45) compared to discontinuation 1

Duration of PPI Therapy: The Critical Answer

Continue pantoprazole for the entire duration of anticoagulation therapy 1, 2:

• For unprovoked PE (which appears to be your patient's situation), anticoagulation should be indefinite/lifelong 1, 4
• PPI therapy must continue for the duration of combined antithrombotic therapy 2
• Since your patient requires lifelong anticoagulation for PE, PPI therapy should also be lifelong 1

The 2022 Circulation guidelines explicitly state: "In an effort to reduce GI bleeding, a proton pump inhibitor should be initiated prophylactically in patients on simultaneous antiplatelet and anticoagulant therapy" and this protection should continue throughout treatment 1.

Rationale for Indefinite Anticoagulation in PE

Your patient requires lifelong anticoagulation because:

• Patients with unprovoked PE have an annual recurrence risk >5% 1, 4
• After a first unprovoked PE, extended anticoagulation is recommended for patients with low to moderate bleeding risk 1, 4
• The benefit of anticoagulation continues only as long as therapy is maintained 1
• Minimum initial treatment is 3-6 months, followed by indefinite therapy 1

Important Clinical Caveats

Reassess the risk-benefit ratio periodically (e.g., annually):

• Monitor for changes in bleeding risk factors 1, 4
• Evaluate renal and hepatic function regularly 1
• Assess drug tolerance and adherence 1

The only scenario to stop anticoagulation at 3 months would be if the PE was provoked by a major transient/reversible risk factor (e.g., surgery), which does not appear to be your case 1, 5.

High bleeding risk patients (which your patient now has demonstrated) still benefit from extended anticoagulation, though the decision becomes more nuanced 1, 4. The fact that resuming anticoagulation after GI bleeding reduces mortality by 38% supports continuation 1.

Practical Algorithm

1. Achieve hemostasis with endoscopic intervention and high-dose PPI
2. Resume Eliquis within 7 days of documented hemostasis 2
3. Continue pantoprazole indefinitely at standard dosing (40 mg daily) 6
4. Reassess annually: bleeding risk, renal function, need for continued anticoagulation 1
5. Never discontinue PPI while patient remains on anticoagulation for PE 1, 2

The evidence strongly supports that stopping PPI therapy while continuing anticoagulation would expose the patient to unacceptable recurrent bleeding risk, particularly given the demonstrated history of GI bleeding 1, 2.
