I have sharp pain radiating from my hip to my leg that has improved, I'm on apixaban (Eliquis) 5 mg daily and am concerned about deep‑vein thrombosis; what should I do?

Seek Immediate Medical Evaluation with Lower Extremity Ultrasound

You need urgent evaluation with a lower extremity ultrasound to rule out DVT, despite being on Eliquis, because your current dose (5 mg daily) is incorrect and insufficient for therapeutic anticoagulation.

Critical Dosing Error

Your current regimen of Eliquis 5 mg daily is not an FDA-approved dose for any indication 1. This represents a significant medication error:

• For DVT/PE treatment: Eliquis should be 10 mg twice daily for 7 days, then 5 mg twice daily 1
• For stroke prevention in atrial fibrillation: 5 mg twice daily (or 2.5 mg twice daily with specific criteria) 1
• For DVT/PE secondary prevention (after ≥6 months treatment): 2.5 mg twice daily 1

Taking only 5 mg once daily provides inadequate anticoagulation and leaves you at risk for thrombosis.

Why You Need Urgent Evaluation

Sharp hip-to-leg pain that has improved does NOT rule out DVT 2. Key considerations:

• Approximately one-third of DVT patients have no symptoms 2
• Symptoms improving could represent partial spontaneous resolution or progression to chronic thrombosis
• Clinical diagnosis alone is unreliable—imaging is required for definitive diagnosis 2
• Untreated DVT can lead to pulmonary embolism in 50-60% of cases with 25-30% mortality 2

Immediate Action Steps

1. Contact your prescribing physician immediately to:

   • Clarify the intended indication for Eliquis
   • Correct the dosing error
   • Arrange urgent lower extremity duplex ultrasound 2

2. Get lower extremity ultrasound (the gold standard initial imaging for suspected DVT) 2

3. Do not stop Eliquis while awaiting evaluation—continue your current dose until instructed otherwise 1

Clinical Decision Algorithm

Your evaluation should follow this pathway 2:

• Clinical assessment + D-dimer testing (if not already done)
• Compression ultrasound of the symptomatic leg from calf to groin
• If ultrasound is positive: Correct anticoagulation dosing immediately
• If ultrasound is negative but high clinical suspicion: Repeat ultrasound in 1 week or consider alternative imaging 2

Correct Anticoagulation Management

If DVT is confirmed 3, 4:

• Start Eliquis 10 mg twice daily for 7 days
• Then continue 5 mg twice daily for at least 3 months
• Duration depends on whether DVT is provoked or unprovoked

If no DVT is found:

• Your physician must clarify why you're on Eliquis
• Correct the dosing based on the actual indication
• Consider alternative diagnoses for your hip-to-leg pain (musculoskeletal, nerve compression, etc.)

Common Pitfalls to Avoid

• Do not assume improvement in symptoms means no DVT—imaging is mandatory 2
• Do not continue incorrect dosing—subtherapeutic anticoagulation provides false reassurance while leaving you vulnerable
• Do not delay evaluation—proximal DVT carries high risk of life-threatening pulmonary embolism 2
• Do not stop anticoagulation abruptly without medical guidance, as this increases stroke/clot risk 1

The combination of concerning symptoms and incorrect anticoagulation dosing creates a high-risk situation requiring immediate medical attention.
