Guidelines for NSAID Use in Patients Taking Eliquis (Apixaban)
Concomitant use of NSAIDs with apixaban should generally be avoided due to significantly increased bleeding risk, but when necessary, careful risk assessment and gastroprotection with a proton pump inhibitor is recommended.
Bleeding Risk Assessment
The combination of NSAIDs and apixaban presents significant concerns due to the compounding bleeding risks:
- NSAIDs inhibit platelet function and can cause gastric erosions
- Apixaban is a direct oral anticoagulant (DOAC) that inhibits factor Xa
- The FDA label for apixaban specifically warns about increased bleeding risk with concomitant NSAID use 1
Evidence of Increased Risk
Research from the ARISTOTLE trial demonstrated that patients with atrial fibrillation who began NSAID use while on apixaban had:
- 61% increased risk of major bleeding (HR 1.61,95% CI 1.11-2.33)
- 70% increased risk of clinically relevant non-major bleeding (HR 1.70,95% CI 1.16-2.48) 2
Decision Algorithm for NSAID Use in Patients on Apixaban
Step 1: Consider Non-NSAID Alternatives First
- Acetaminophen (up to 3g/day with renal impairment)
- Topical analgesics (lidocaine, capsaicin)
- Non-pharmacological approaches (physical therapy, heat/cold therapy)
Step 2: If NSAID Required, Assess Risk Factors
High-risk patients (avoid NSAIDs if possible):
- Age ≥65 years
- History of GI bleeding or peptic ulcer disease
- Concurrent use of other antithrombotics (aspirin, P2Y12 inhibitors)
- Severe renal impairment
- Uncontrolled hypertension
- Heart failure
Step 3: If NSAID Use Unavoidable
For short-term use:
- Use lowest effective dose for shortest duration
- Select naproxen (has lower cardiovascular risk profile) 3
- Add proton pump inhibitor (PPI) for gastroprotection
- Monitor blood pressure and renal function
- Watch for signs of bleeding (bruising, melena, hematemesis)
For chronic use:
- Strong consideration of alternative pain management strategies
- Mandatory PPI co-therapy
- Regular monitoring of hemoglobin, renal function, and blood pressure
- Consider temporary interruption of apixaban for procedures with high bleeding risk 4
Special Considerations
Cardiovascular Risk
- NSAIDs increase cardiovascular risk through COX-2 inhibition 4
- Patients on apixaban often have underlying cardiovascular disease
- If NSAID needed, naproxen has shown less cardiovascular risk than other NSAIDs 5
Gastrointestinal Protection
- PPI co-therapy reduces risk of NSAID-induced gastropathy by 54% 6
- All patients on combined NSAID and apixaban therapy should receive PPI prophylaxis 4
Renal Considerations
- Both NSAIDs and apixaban can affect renal function
- Avoid NSAIDs in patients with CrCl <30 mL/min
- Monitor renal function within 1-2 weeks of starting therapy 5
Common Pitfalls to Avoid
- Failure to recognize OTC NSAID use: Many patients don't report over-the-counter NSAID use
- Inadequate gastroprotection: PPI should be prescribed concurrently, not just "as needed"
- Prolonged NSAID use: What begins as short-term therapy often extends indefinitely
- Ignoring early warning signs: Minor bleeding events may precede major complications
- Drug interactions: Some NSAIDs may interact with apixaban through P-glycoprotein or CYP3A4 pathways
Monitoring Recommendations
For patients requiring concomitant NSAID and apixaban therapy:
- Blood pressure check within 1-2 weeks of starting therapy
- Renal function testing within 1-2 weeks and every 3 months thereafter
- Hemoglobin/hematocrit monitoring
- Patient education on signs of bleeding to report immediately
The evidence clearly indicates that while this combination increases bleeding risk, careful selection of patients, appropriate gastroprotection, and vigilant monitoring can help manage these risks when the combination cannot be avoided.
