Apixaban (brand name: Eliquis) is one of a group of medications often referred to as newer oral anticoagulants, novel oral anticoagulants, or NOACs. Anticoagulants are often referred to as blood-thinning medications, but what they actually do is make it take longer for blood to clot. This is important for people who have atrial fibrillation (Afib or AF) and, therefore, are at increased risk for stroke. If you have Afib, your doctor may have prescribed an anticoagulant to reduce your risk for stroke.
The benefit of anticoagulant medications is that they keep the blood from clotting. This is also a risk that comes with taking anticoagulants: They can prevent the blood from clotting when it needs to and can cause dangerous internal bleeding. For most people with Afib, the risk of a blood clot causing a stroke is greater than the risks that come with taking an anticoagulant. The decision to take an anticoagulant – and which one – needs to be carefully evaluated for each person, depending on your individual risk factors, medical history, ability to take medications exactly as prescribed and, in the case of warfarin (Coumadin), willingness to have regular blood tests that are used to monitor the effects of the drug.

This page is meant to familiarize you with apixaban and how it may be used to prevent blood clots that can cause stroke. Note: This information is intended only to provide an overview. It should not take the place of a doctor’s recommendation. Be sure to speak with your doctor about your condition, symptoms and treatment options.
Benefits & Limitations of Apixaban
If you are taking the anticoagulant warfarin (Coumadin), you will need to have regular blood tests (called International Normalization Ratio, or INR, checks) to monitor for abnormal bleeding. Apixaban (like the other newer oral anticoagulants) does not require these tests. Nevertheless, apixaban (again, like the other newer oral anticoagulants) can cause bleeding complications, some of which can be dangerous. As of fall 2015, rivaroxaban does not have an antidote available to counteract excessive bleeding and restore the body’s blood-clotting factors. (Warfarin and dabigatran do have antidotes.) You can learn more about antidotes here.
As with all medications, it is important that apixaban be taken exactly as the directions specify.
If you are prescribed apixaban, then you must take precautions to ensure that it does not interact with other medications (prescribed and over-the-counter), supplements and vitamins that you may be taking. This is why it is important to tell your care team about everything you take, including vitamins and supplements.
Apixaban & Interactions
Apixaban can interact negatively with certain prescription and over-the-counter medications as well as some supplements. This is why it is important to talk with your doctor about any medications you take – either regularly or occasionally.
Signs of Problems If You Are Taking Apixaban
If you are taking apixaban, you should be alert for any changes that could signal a bleeding problem; a negative interaction with a medication, food or supplement; or other issues.
The following symptoms should be considered a medical emergency. If any of these symptoms occur, it is necessary to contact your doctor immediately:
- A severe allergic reaction known as anaphylaxis. Symptoms of this include a rash; trouble swallowing; swelling of the mouth, tongue, face, lips, throat, hands or neck; itching or hives.
- Severe bleeding (In women, this may include a heavier-than-normal menstrual period.)
- Urine that is red or brown in color
- Frequent nosebleeds
- Stools that appear bloody or black in color
- Joint pain as well as swelling and discomfort in joints
- Bruising when you have not taken a fall or bumped into something
- Vomiting of blood (or of anything that resembles coffee grounds)
- Severe weakness or dizziness
- Severe headache or stomachache
Other symptoms that indicate problems include bleeding of your gums when you brush your teeth, unexplained fever, diarrhea or vomiting that lasts more than 24 hours.
If you have been recently diagnosed with atrial fibrillation, it is likely you have a number of questions to ask your doctor about your condition. To get you started, we invite you to download Questions to Ask Your Doctor About Atrial Fibrillation.
If you and your doctor are considering anticoagulant therapy, you may have specific questions about how it will affect you. Some common questions are provided in SecondsCount’s article on What You Need to Know About Anticoagulant Medications.
