Apixaban

Apixaban is a direct oral anticoagulant (DOAC) — often called a blood thinner. In the UK it is prescribed to reduce the risk of stroke and blood clots in people with atrial fibrillation when a clinician judges anticoagulation is appropriate, and to treat or prevent some types of venous thrombosis (such as DVT or PE) depending on the situation.

Your prescriber will explain how long you need it and any planned procedures where it may need to be paused.

Apixaban blocks one of the clotting factors in the blood (factor Xa), which makes blood less likely to form harmful clots in the heart or veins.

It works differently from Warfarin — it does not require the same routine INR blood tests, but monitoring and safety advice still matter.

Dosing schedules vary — many people take apixaban twice daily, but some regimens differ after surgery or for clot treatment. Follow your own prescription exactly.

Swallow tablets with water, with or without food as directed. Do not stop or change dose without medical advice unless you are told to for a procedure.

Common effects include bruising more easily, nosebleeds, or minor bleeding from gums. Many people have no troublesome effects.

Nausea, tiredness, or anaemia can occur — report heavy periods or prolonged bleeding to your GP.

Seek urgent help for severe bleeding (vomiting blood, black stools, large bruises, sudden severe headache, blood in urine), or signs of a clot such as new leg swelling, chest pain, or breathlessness if tablets were stopped inappropriately.

Spinal procedures and head injury carry special risks on anticoagulants — always tell clinicians you take apixaban.

If you miss a dose, follow the missed-dose instructions in your leaflet — timing depends on whether you are due the next dose soon. Do not double up unless your prescriber or anticoagulant service has told you to.

If you are unsure after a missed dose, ring your GP practice, anticoagulant clinic, or NHS 111 for advice.

Apixaban is not suitable for everyone — for example active major bleeding, certain mechanical heart valves in some guidelines, and severe kidney or liver impairment need individual assessment.

Always give a full history of bleeding problems, ulcers, and all medicines including Aspirin and anti-inflammatory painkillers.

NSAIDs such as Ibuprofen or Naproxen increase bleeding risk and are often avoided or used only with medical advice. Some antifungals, HIV medicines, and epilepsy drugs can alter apixaban levels.

Always check before starting new prescription, herbal, or over-the-counter medicines.

Anticoagulation in pregnancy needs specialist planning — discuss with your GP or clinic if you could become pregnant or are pregnant.

Kidney function may be checked periodically. You may have an anticoagulant review after starting or if your health changes. Attend appointments before surgery or dental extraction.

Your clinician may consider other DOACs, Warfarin, or Aspirin in selected situations — choice depends on your condition, kidneys, interactions, and bleeding risk.
