Information about Lixiana▼

What is it and what is it used for?

Lixiana is an anticoagulant medicine (a medicine that prevents blood clotting) used in adults:

  • to prevent stroke (caused by blood clots in the brain) and systemic embolism (blood clots in other organs) in patients with non-valvular atrial fibrillation (irregular rapid contractions of the upper chambers of the heart). It is used in patients who have one or more risk factors, such as having had a previous stroke, high blood pressure, diabetes, heart failure or being 75 years old or over;
  • to treat deep-vein thrombosis (DVT, a blood clot in a deep vein, usually in the leg) and pulmonary embolism (a clot in a blood vessel supplying the lungs), and to prevent DVT and pulmonary embolism from re-occurring.
How Lixiana works
The active substance in Lixiana, edoxaban, is a ‘factor Xa inhibitor’. This means that it blocks factor Xa, an enzyme that is involved in the production of thrombin. Thrombin is essential for blood clotting. By blocking factor Xa, the medicine reduces the levels of thrombin in the blood, which helps treat clots and reduce the risk of them forming in the arteries and veins and leading to DVT, pulmonary embolism, stroke or other organ damage.

How Lixiana is used
Lixiana is available as tablets (15, 30 and 60 mg) and can only be obtained with a prescription. The usual dose is 60 mg once a day. Treatment is continued while the benefit outweighs the risk of bleeding, which depends on the condition being treated and any existing risk factors. Doses should be halved in patients with moderately or severely reduced kidney function, or low body weight or in those who are also taking certain medicines (known as P-gp inhibitors) that can interfere with the removal of edoxaban from the body. Dose adjustments may also need to be made in patients who are switched between Lixiana and other anticoagulant medicines. For further information, see the package leaflet.

What are the benefits?

The European Medicine Agency decided that Lixiana’s benefits are greater than its risks and recommended that it be approved for use in the EU. The medicine has been shown to be at least as effective as warfarin in reducing stroke rates in patients with atrial fibrillation and in preventing further episodes of DVT or pulmonary embolism. However, the trend for its benefits in preventing stroke in atrial fibrillation to be less clear in those patients with high creatinine clearance (good kidney function) was considered to require further study.

With respect to safety, overall the risk of serious bleeding such as bleeding into the brain was reduced compared with warfarin, although there may be less difference where warfarin treatment is well managed. Although there was greater a risk of bleeding from the mucosa (tissues lining body cavities such as the nose, gut and vagina), the Agency considered that the risk could be managed with appropriate measures.

What are main side effects?

The most common side effects with Lixiana (which may affect up to 1 in 10 people) are bleeding from skin and soft tissues, nose bleeds (epistaxis) and the vagina. Bleeding can occur at any site and can be severe or even fatal.

Other common side effects are:
  • anaemia (low levels of red blood cells)
  • rash
  • itching
  • headache
  • dizziness
  • belly pain
  • abnormal results in tests of liver function
For the full list of all side effects reported with Lixiana, see the package leaflet.

Who should avoid taking it?

Lixiana must not be used in patients who are actively bleeding, have liver diseases that affect blood clotting, have severe uncontrolled high blood pressure or who have a condition putting them at significant risk of major bleeding.

It must also not be used in pregnant or breastfeeding women or in patients also being treated with another anticoagulant.

For the full list of restrictions, see the package leaflet.

What studies have been done?

Lixiana has been shown to be as effective as the standard anticoagulant warfarin in preventing stroke and systemic embolism in patients with atrial fibrillation. The effects were studied in one main study, which involved over 21,000 patients for an average of 2.5 years. The main measure of effectiveness was the rate of stroke or systemic embolism among the patients each year. A first systemic embolism or stroke occurred in 182 patients given standard doses of Lixiana and in 232 of those given warfarin, corresponding to annual rates for these events of around 1.2% and 1.5% respectively. When another recommended definition of the type of stroke was used, embolism or stroke due to blood clots was seen in 143 patients given Lixiana (0.9%) and 157 given warfarin (1%). There was a trend for better results in patients with reduced kidney function than those whose kidney function was normal.

In the treatment and prevention of blood clots in patients with DVT or pulmonary embolism, Lixiana was also found to be as effective as warfarin, in a study involving over 8,200 patients. The main measure of effectiveness was the number of patients who had another episode of DVT or pulmonary embolism during the study period. Further episodes were seen in 130 of 4,118 patients given edoxaban (3.2%) and in 146 of 4,122 given warfarin (3.5%).


Lixiana was first approved for use in the EU in 2015. It is manufactured by Daiichi Sankyo.

New medicines and vaccines that are under additional monitoring have an inverted black triangle symbol (▼) displayed in their package leaflet and summary of product characteristics, together with a short sentence explaining what the triangle means – it does not mean the medicine is unsafe. You should report all suspected adverse drug reactions (ADRs) for these products. ADRs can be reported by your doctor, pharmacist or online via the Yellow Card system.

Reporting of suspected adverse reactions

Reporting suspected adverse reactions (side effects) after authorisation of the medicinal product is important. It allows continued monitoring of the benefit/risk balance of the medicinal product. Healthcare professionals or patients are asked to report any suspected adverse reactions via the Yellow Card Scheme at or search for MHRA Yellow Card in the Google Play or Apple App Store.
