Edoxaban โ€” NZ Medication Guide

What is Edoxaban?

Edoxaban is a direct oral anticoagulant (DOAC) โ€” a direct factor Xa inhibitor โ€” used for stroke prevention in atrial fibrillation and treatment of venous thromboembolism. This medication is funded by Pharmac under Special Authority for AF and VTE.

What is Edoxaban Used For?

Edoxaban is used for stroke and systemic embolism prevention in non-valvular atrial fibrillation, and treatment and prevention of DVT and PE after initial parenteral anticoagulation.

How Does Edoxaban Work?

Edoxaban directly and reversibly inhibits factor Xa, blocking the conversion of prothrombin to thrombin and preventing clot formation. It has a longer half-life than rivaroxaban (10โ€“14 hours) and is administered once daily.

How to Take Edoxaban

Standard adult dose: 60 mg once daily (at the same time each day). Dose reduced to 30 mg once daily in patients with renal impairment (eGFR 15โ€“50 mL/min), low body weight (โ‰ค60 kg), or taking certain P-gp inhibitors. For VTE treatment: requires initial 5โ€“10 days of parenteral anticoagulation (heparin) before switching to edoxaban.

Common Side Effects of Edoxaban

  • Bleeding (any site)
  • Anaemia
  • Rash
  • Elevated liver enzymes

Serious Side Effects โ€” Seek Medical Attention

Contact your doctor or call 111 immediately if you experience any of the following:

  • Major bleeding events
  • Spinal/epidural haematoma (with neuraxial anaesthesia)
  • Rebound thromboembolism if stopped abruptly without a transition plan

Drug Interactions

Edoxaban may interact with other medicines. Always inform your doctor and pharmacist of all medications you are taking. Key interactions include:

  • P-gp inhibitors (amiodarone, verapamil, quinidine โ€” increase edoxaban levels โ€” dose reduction required)
  • P-gp inducers (rifampicin, carbamazepine, St John’s Wort โ€” reduce levels โ€” avoid)
  • NSAIDs and antiplatelets (increased bleeding risk)
  • Antifungals (azole group โ€” increase levels)

New Zealand Prescribing Information

Edoxaban (30 mg, 60 mg tablets โ€” Lixianaยฎ) is funded by Pharmac under Special Authority for non-valvular AF and VTE treatment. It requires an initial period of parenteral anticoagulation before transition for VTE treatment. Renal function monitoring is essential โ€” dose reduction criteria must be assessed at initiation and reviewed regularly.

Frequently Asked Questions

How is edoxaban different from apixaban and rivaroxaban?

All three are direct factor Xa inhibitors. Edoxaban and rivaroxaban are once daily, while apixaban is twice daily. Edoxaban for VTE requires initial heparin treatment before switching. The choice between these agents is guided by indication, renal function, dosing preference, and specific drug interactions.

Should I stop edoxaban before a procedure or surgery?

Yes โ€” edoxaban should generally be stopped 24โ€“48 hours before elective procedures, or longer for high-bleeding-risk surgery or if renal function is impaired. Always consult your cardiologist or haematologist about timing and any bridging therapy needed.
