Eliquis (apixaban) Tablets
What is it used for? Preventing dangerous…
What is it used for?
- Preventing dangerous blood clots in the veins (venous thromboembolism) in adults who have undergone elective total hip or knee replacement surgery.
- Treating blood clots in the veins of the legs (deep vein thrombosis) or in the lungs (pulmonary embolism).
- Preventing recurrent deep vein thrombosis and pulmonary embolism.
- Preventing the formation of blood clots that can cause a stroke or blockage of other blood vessels in the body in people with a type of irregular heartbeat called atrial fibrillation (AF). This medicine is licensed to prevent blood clots in people with AF who have one or more of the following additional risk factors:
- age over 75 years
- a history of stroke or mini stroke (TIA)
- heart failure
- high blood pressure
How does it work?
- Eliquis tablets contain the active ingredient apixaban, which is a type of medicine called an anti-thrombotic. It is used to stop blood clots forming within the blood vessels.
- Blood clots usually only form to stop bleeding that has occurred as a result of injury to tissue in the body. The blood clotting process is complicated. When blood begins to clot, a cascade of chemicals is activated within the body, resulting in the formation of an enzyme called thrombin.
- Thrombin is central to the complete process of blood clotting. It causes a protein called fibrinogen to be converted into another called fibrin. Fibrin binds blood cells called platelets together and this forms the blood clot. This is the body's natural way of repairing itself.
- Sometimes however, there is an increased tendency for blood clots to form within the blood vessels. This is usually due to a disturbance in the blood flow within the blood vessels. For example, people with a type of fast irregular heartbeat called atrial fibrillation (AF) are at risk of blood clots forming, both within the heart and in the blood vessels. This is because the abnormal heart rhythm disrupts blood flow in the blood vessels. Clots in the heart can detach and travel to the brain, causing a stroke. Clots can also travel in and block other blood vessels around the body.
- After hip or knee replacement surgery there is also a risk of blood clots forming in the blood vessels. This risk is increased by being immobile for long periods of time following the surgery, as a result of slowed blood flow in the leg and pelvic veins. A clot that forms in the veins of the leg is called a deep vein thrombosis. These dangerous blood clots can travel to the lungs, causing a serious condition called a pulmonary embolism.
- Apixaban is used to prevent and treat these types of blood clots. It works by binding to a substance called factor Xa, which is required for the formation of clotting components thrombin and fibrin. By binding to factor Xa apixaban helps prevent the formation of blood clots.
How do I take it?
- Eliquis tablets can be taken either with or without food. They should be swallowed with a drink of water.
- The dose prescribed and how long the medicine needs to be taken depends on the reason for taking the medicine. It is important to follow the instructions given by your doctor. These will be printed on the dispensing label that your pharmacist has put on the packet of medicine. If you are unsure about anything, ask your pharmacist for advice.
- The tablets are usually taken twice a day, morning and evening. Try to always take them at the same times each day.
- If you forget to take a tablet, you should take one as soon as you remember and then continue taking the tablets twice a day at your usual times.
- Do not stop taking this medicine until you have been advised to by your doctor.
- The medicine is usually taken twice a day for 10 to 14 days following a knee replacement and for 32 to 38 days following a hip replacement.
- To treat a blood clot in the leg or lungs the medicine is usually taken twice a day at a high dose for seven days and then twice a day at a reduced dose for three to six months. To prevent recurrent blood clots in the legs or lungs the dose is further reduced after the six months of treatment, and this is continued twice a day on a long-term basis. Follow the instructions given by your doctor.
- For preventing blood clots in people with AF the medicine is usually taken twice a day on a long-term basis.

How can this medicine affect other medicines?
It is important to tell your doctor or pharmacist what medicines you are already taking, including those bought without a prescription and herbal medicines, before you start treatment with this medicine. Similarly, check with your doctor or pharmacist before taking any new medicines while taking this one, to make sure that the combination is safe.
The medicines listed below increase the blood level of apixaban, which could increase the risk of bleeding. Apixaban is not recommended for people taking these medicines:
- azole antifungal medicines such as ketoconazole, itraconazole, posaconazole and voriconazole
- protease inhibitors such as atazanavir, boceprevir, darunavir, fosamprenavir, indinavir, lopinavir, nelfinavir, ritonavir, saquinavir, telaprevir and tipranavir.
This medicine will enhance the effect of other anticoagulant medicines used to treat and prevent blood clots, such as those listed below. For this reason, it should not be used in combination with these medicines (except if treatment is being switched to or from Eliquis):
- heparin (unless this is being used to stop blood clots forming in a central line)
- low-molecular weight heparins, eg dalteparin, enoxaparin, tinzaparin
There may be an increased risk of bleeding if this medicine is used in combination with other medicines that can affect blood clotting, such as those listed below:
- aspirin (including low-dose aspirin to 'thin the blood')
- glycoprotein IIb/IIIa receptor antagonists, eg abciximab, eptifibatide and tirofiban

- SSRI antidepressants such as fluoxetine, fluvoxamine, paroxetine, citalopram
- thrombolytic agents (clot-busters), eg alteplase, streptokinase
The following medicines may reduce the amount of apixaban in the blood, which could make it less effective at preventing blood clots:
- the herbal remedy St.John'st (Hypericum perforatum).
