Direct Oral Anticoagulant (DOAC) — Factor Xa Inhibitor Pregnancy: No data in pregnant women; as a precautionary measure preferable to avoid use during pregnancy. Breast-feeding: a risk to the suckling child cannot be excluded.

Apixaban

Brand names: Eliquis

Apixaban is a direct oral anticoagulant (DOAC) — a factor Xa inhibitor — for atrial-fibrillation stroke prevention and for VTE treatment and prevention.

Auto-extracted from the source labelling — not yet independently clinician-verified. These values were distilled from the UK SPC (or the US label where noted) but have not had a clinician sign-off. Confirm against the current SmPC before prescribing.

Adult dose

Dose: Indication-dependent. NVAF (stroke/systemic embolism prevention): 5 mg twice daily. VTE prophylaxis after elective hip/knee replacement (VTEp): 2.5 mg twice daily. Treatment of DVT/PE (VTEt): 10 mg twice daily for the first 7 days, then 5 mg twice daily; prevention of recurrent DVT/PE: 2.5 mg twice daily.
Route: Oral
Frequency: Twice daily
Max: 20 mg daily (10 mg twice daily) during first 7 days of DVT/PE treatment
VTEp (elective hip or knee replacement): 2.5 mg twice daily, initial dose 12-24 hours after surgery; duration 32-38 days (hip) or 10-14 days (knee). NVAF: 5 mg twice daily long-term; DOSE REDUCTION to 2.5 mg twice daily if at least TWO of: age >= 80 years, body weight <= 60 kg, or serum creatinine >= 1.5 mg/dL (133 micromole/L). VTEt (treatment of acute DVT and PE): 10 mg twice daily for first 7 days followed by 5 mg twice daily; short treatment duration (at least 3 months) based on transient risk factors. Prevention of recurrent DVT and PE: 2.5 mg twice daily, initiated after completion of 6 months of treatment with apixaban 5 mg twice daily or another anticoagulant. Combined P-gp and strong CYP3A4 inhibitors: reduce dose by 50% for patients on 5 mg or 10 mg twice daily; avoid if on 2.5 mg twice daily.

Dose adjustments

Renal

Mild/moderate impairment: no dose adjustment for VTEp/VTEt; for NVAF only if dose-reduction criteria met. Severe renal impairment (CrCl 15-29 mL/min): VTEp/VTEt use with caution; NVAF give lower dose 2.5 mg twice daily. CrCl < 15 mL/min or dialysis: not recommended.

Contraindications

  • Hypersensitivity to the active substance or to any of the excipients
  • Active clinically significant bleeding
  • Hepatic disease associated with coagulopathy and clinically relevant bleeding risk
  • Lesion or condition considered a significant risk factor for major bleeding (e.g. current/recent GI ulceration, malignant neoplasms at high risk of bleeding, recent brain/spinal injury, recent brain/spinal/ophthalmic surgery, recent intracranial haemorrhage, known/suspected oesophageal varices, arteriovenous malformations, vascular aneurysms, major intraspinal or intracerebral vascular abnormalities)
  • Concomitant treatment with any other anticoagulant agent (e.g. UFH, low molecular weight heparins, heparin derivatives, oral anticoagulants) except under specific circumstances of switching anticoagulant therapy or catheter maintenance/ablation

Side effects

  • Haemorrhage, haematoma (common)
  • Anaemia (common)
  • Epistaxis (common)
  • Contusion
  • Nausea; thrombocytopenia (common in VTEt)

Interactions

  • Other anticoagulants — concomitant use contraindicated (increased bleeding risk)
  • Antiplatelet agents (including acetylsalicylic acid) — increase risk of bleeding
  • SSRIs / SNRIs and NSAIDs — take care due to bleeding risk
  • Combined P-gp and strong CYP3A4 inhibitors (ketoconazole, itraconazole, ritonavir) — increase apixaban exposure; reduce dose by 50% (or avoid if on 2.5 mg BD)
  • Combined P-gp and strong CYP3A4 inducers — decrease apixaban exposure; avoid concomitant use

Clinical monograph

How it works

It directly and reversibly inhibits activated factor X (Xa), reducing thrombin generation.

Prescribing in practice

  • It needs no routine coagulation monitoring, but the dose depends on the indication and on criteria (age, weight, renal function — the reduced-dose AF criteria).
  • Avoid in severe renal impairment and in significant hepatic impairment with coagulopathy; bleeding is the main risk (specific reversal with andexanet alfa where available).
  • It is taken twice daily — adherence matters.

Monitoring

Monitor renal and hepatic function periodically and the full blood count; watch for bleeding.

Counselling the patient

  • Take it regularly, twice a day.
  • Report any bleeding or black stools.
  • Tell clinicians you take it before surgery or dental work.

Evidence & guidelines

At least as effective as warfarin for AF with less intracranial bleeding (ARISTOTLE; NICE NG196).
