Medicines to prevent stroke when you have atrial fibrillation 

Atrial fibrillation is a condition where the heartbeat becomes fast and irregular. This can increase the chances of a blood clot forming. Blood clots that go to the brain can cause a stroke, damaging part of the brain.

Oral anticoagulants (an-tee-koh-AG-yuh-luhnts) are medicines that make it harder for blood to clot. Some people call them blood thinners.

If you are prescribed an anticoagulant, it is important to understand why you need it, how to take it safely and what side effects to watch out for.

Atrial fibrillation (AF) is when your heartbeat speeds up and loses its regular rhythm. For some people, changes to the heartbeat happen in bursts, for others it is most or all the time. 

Anyone can get atrial fibrillation, and it can happen at any age, although it is more common as people get older, and in those with risk factors like high blood pressure. More than half a million Australians were living with AF in 2020.  

You may get symptoms like palpitations (feeling that your heart is beating too fast or not regularly), dizziness, or shortness of breath, or have no symptoms at all.  

 

 

 

 

Atrial fibrillation affects how the heart pumps blood. Blood that doesn’t flow properly can clot inside the heart. Clots that form this way can break loose and travel through the body. If a clot reaches the brain, it can block a blood vessel and stop blood from getting through, which causes damage. This damage can affect how you talk, swallow, move and think. The damage can be permanent (lasts forever) or temporary (goes away). 

Blood clots are usually a normal part of healing. They stop blood flowing from a blood vessel. When a clot forms in a blood vessel that is not damaged, it can block the normal flow of blood and is dangerous to your health.

Being told you have atrial fibrillation may leave you feeling concerned and confused. But you are not alone. Many Australians have this condition and continue to live busy and active lives. Atrial fibrillation can usually be managed with medicines, a healthy lifestyle and regular medical checks.

Treatment for atrial fibrillation will be different for each person. It is important to talk with your doctors about what your needs are when it comes to treating atrial fibrillation. Some people will need medicines; others might need to have a medical procedure. Choices about treatment will also consider symptoms, the cause, and any other health conditions a person might have.  

Overall, there are four main areas of treatment that your health professionals might talk to you about: 

1. Rate control these treatments aim to bring the heart rate back into the normal range (60-100 beats per minute). 

2. Rhythm control – these treatments aim to restore normal rhythm (also called sinus rhythm).  

Some people will take medicines to help control their rate or rhythm. Other people may need a medical procedure instead.

 

3. Anticoagulationthese are medicines that can help lower the risk of a stroke by making it harder for clots to form in the heart (see What are oral anticoagulants?) 

4. Risk factor management these are other health conditions that make it more likely for a person to develop atrial fibrillation (see What else can I do to manage atrial fibrillation?)

Taking care of your heart and general health is an important step in managing atrial fibrillation. This includes helpful actions such as: 

  • Being a healthy weight  
  • Stopping smoking
  • Reducing alcohol 
  • Staying active 
  • Keeping other health conditions in control – such as blood pressure and cholesterol levels. 

To find more information about living well with atrial fibrillation read the Anticoagulants Care Plan.

Atrial fibrillation is a major cause of stroke in Australia. Research shows that the risk of stroke is up to five times greater in people who have atrial fibrillation than in people who do not. This is because atrial fibrillation affects the heart’s ability to pump blood effectively.  

This can lead to blood pooling and make it more likely that a clot will form. If a clot travels up to your brain, it can block the blood flow and cause a stroke. 

If you have atrial fibrillation, your doctor or specialist can check your stroke risk and prescribe the most suitable treatment (like an anticoagulant medicine) to help keep you safe. Even if you feel fine, atrial fibrillation still raises your stroke risk, so acting early and getting the right treatments is best. 

 

Clots can also travel through other blood vessels in your body and block blood flow to your arms or legs, or even one of your vital organs (like your lungs). So, taking an anticoagulant may have other benefits too. 

If you have atrial fibrillation, your risk of stroke may be higher if you: 

  • Are 65 years or older  
  • Have high blood pressure
  • Have type 2 diabetes  
  • Have heart failure  
  • Have had a previous stroke  
  • Have heart disease  

The best action you can take is to ask your doctor to check your stroke risk. Even if you feel fine, acting early and getting the right treatments for you is best.

Oral anticoagulants are sometimes called blood thinners, but they don’t make the blood thinner. Instead, they work by slowing down the body’s clotting process. This helps prevent harmful blood clots that can cause a stroke, while still allowing the blood to clot when needed for minor injuries like a nosebleed. 

You are taking an anticoagulant if your medicine has one of these active ingredients in it: 

  • Apixaban (a-pix-a-ban) 
  • Dabigatran (da-big-a-tran) 
  • Rivaroxaban (ri-va-roks-a-ban)
  • Warfarin (waw-fuh-rin) 

Apixaban, dabigatran and rivaroxaban are also known as ‘DOACs’ (direct-acting oral anticoagulants). Patient information sheets for these three medicines can be found in English and 5 other languages from the NSW Health Clinical Excellence Commission.

Many people who have atrial fibrillation take an anticoagulant every day. This helps lower their risk of a stroke by almost 70%!

People with atrial fibrillation also need other treatments to help their heart health and control abnormal heartbeats.

All medicines have benefits (good outcomes that help our health) and unwanted effects (also called side effects).

 

Side effects from taking an anticoagulant are increased risks of bleeding and bruising.

Serious internal bleeding (in the gut or brain) can happen but is very rare.

 

These side effects need to be balanced against the benefit of lowering stroke risk. No anticoagulation can lead to a blood clot, but too much anticoagulation can lead to uncontrolled or serious bleeding.

If you take apixaban, dabigatran, rivaroxaban or warfarin it is important to use the medicine safely and correctly.

Before you start taking your anticoagulant medicine for the first time, your doctor will do a complete blood test and check the health of your liver and kidneys (often described as liver function and kidney function).

Your doctor will need to check your kidney function at least once every year, and re-check it if your health condition or medicines change.

If you take warfarin, your doctor or nurse will organise routine blood tests to monitor how it is working.

While you are taking anticoagulants, you will need to take care with activities that could lead to injury or cause bleeding. Talk with your health professional about actions you can take to reduce the chance of bleeding or bruising. This might include using gloves in the garden, changing the type of razor you use for shaving, or even using a softer toothbrush so you do not hurt your gums when brushing your teeth.

You should contact your health professional immediately and get urgent medical attention if you have:

  • Nose bleeds that do not stop
  • Coughing or vomiting blood (may look like soil/ coffee grind)
  • Blood in urine or bowel movements (may look dark like tar)
  • Bleeding or bruising that gets worse
  • Sudden and severe headache

Top tips for people taking an anticoagulant

  • Take the anticoagulant exactly as prescribed and at the same time every day.
  • Know what to do if you miss a dose.
  • Make sure all your health professionals know you are taking an anticoagulant. This includes your blood collector, dentist, dietitian, GP, nurse, pharmacist, physiotherapist, podiatrist and specialist. A medicines list can be a useful way to keep all the information about your medicines together.
  • Use a medical alert card or bracelet.
  • Check with a health professional before taking any new medicines, in case there is a risk of interactions. This includes non-prescription and complementary medicines such as herbs and vitamins.
  • If you are specifically taking warfarin, here are some. Do not stop taking your anticoagulant without talking to your prescriber first. Stopping can put you at increased risk of developing a blood clot.
