If you have atrial fibrillation (a condition where the heart beats irregularly and can lead to blood clots and stroke) and are taking apixaban to help prevent strokes or serious blood clots, you are at a higher risk of having a stroke after you stop taking this medication. Do not stop taking apixaban without talking to your doctor. Continue to take apixaban even if you feel well. Be sure to refill your prescription before you run out of medication so that you will not miss any doses of apixaban. If you need to stop taking apixaban, your doctor may prescribe another anticoagulant ('blood thinner') to help prevent blood clots and lower your risk of stroke.
If you have epidural or spinal anesthesia or a shot in your spine while taking a 'blood thinner' such as apixaban, you could get a blood clot near your spine that can cause paralysis. Tell your doctor if you have a tube in your spine, or if you have had spine problems, back surgery, or more than one spinal shot. Tell your doctor and pharmacist if you are taking any of the following: anagrelide; aspirin and other nonsteroidal anti-inflammatory drugs (NSAIDs) such as ibuprofen ® , indomethacin, ketoprofen, and naproxen; cilostazol; clopidogrel; dipyridamole; eptifibatide; heparin; prasugrel; ticagrelor; ticlopidine; tirofiban, and warfarin. Call your doctor immediately if you experience muscle weakness (especially in your legs and feet), numbness or tingling (especially in your legs), or trouble controlling your bladder or bowels.
Your doctor or pharmacist will give you the manufacturer's patient information sheet (Medication Guide) when you begin treatment with apixaban and each time you refill your prescription.

You can also visit the Food and Drug Administration (FDA) website ( https://www.fda.gov/Drugs/DrugSafety/ucm085729.htm ) or the manufacturer's website to obtain the Medication Guide.Talk to your doctor about the risks of taking apixaban.
