WARNINGS: (A) DISCONTINUING XARELTO IN PATIENTS WITH NONVALVULAR ATRIAL FIBRILLATION INCREASES RISK OF STROKE, (B) SPINAL/EPIDURAL HEMATOMA
A. DISCONTINUING XARELTO IN PATIENTS WITH NONVALVULAR ATRIAL FIBRILLATION
Discontinuing XARELTO places patients at an increased risk of thrombotic events. An increased rate of stroke was observed following XARELTO discontinuation in clinical trials in atrial fibrillation patients. If anticoagulation with XARELTO must be discontinued for a reason other than pathological bleeding, consider administering another anticoagulant [see Dosage and Administration, Warnings and Precautions, and Clinical Studies].
B. SPINAL/EPIDURAL HEMATOMA
Epidural or spinal hematomas have occurred in patients treated with XARELTO who are receiving neuraxial anesthesia or undergoing spinal puncture. These hematomas may result in long-term or permanent paralysis. Consider these risks when scheduling patients for spinal procedures. Factors that can increase the risk of developing epidural or spinal hematomas in these patients include:
use of indwelling epidural catheters
concomitant use of other drugs that affect hemostasis, such as non-steroidal anti-inflammatory drugs (NSAIDs), platelet inhibitors, other anticoagulants
a history of traumatic or repeated epidural or spinal punctures
a history of spinal deformity or spinal surgery
[see Warnings and Precautions (5.2, 5.3) and Adverse Reactions].
Monitor patients frequently for signs and symptoms of neurological impairment. If neurological compromise is noted, urgent treatment is necessary [see Warnings and Precautions].
Consider the benefits and risks before neuraxial intervention in patients anticoagulated or to be anticoagulated for thromboprophylaxis [see Warnings and Precautions].
Rivaroxaban, a factor Xa inhibitor, is the active ingredient in XARELTO Tablets.
Reduction of Risk of Stroke and Systemic Embolism in Nonvalvular Atrial Fibrillation
XARELTO (rivaroxaban) is indicated to reduce the risk of stroke and systemic embolism in patients with nonvalvular atrial fibrillation.
There are limited data on the relative effectiveness of XARELTO and warfarin in reducing the risk of stroke and systemic embolism when warfarin therapy is well-controlled [see Clinical Studies].
Prophylaxis of Deep Vein Thrombosis
XARELTO (rivaroxaban) is indicated for the prophylaxis of deep vein thrombosis (DVT), which may lead to pulmonary embolism (PE) in patients undergoing knee or hip replacement surgery.

Clinical Trials Related to Xarelto (Rivaroxaban)
Rivaroxaban for Treatment of Patients With Suspected or Confirmed Heparin-Induced Thrombocytopenia [Recruiting]
Heparin is an anticoagulant (blood thinner) that is commonly used to treat patients with
heart attacks and patients with blood clots in their legs or lungs (venous thrombosis). Some
patients develop an allergic reaction to heparin, a condition called heparin-induced
thrombocytopenia (HIT). HIT makes blood clot, which is the opposite of what heparin was
designed to do. These blood clots can lead to heart attacks, strokes, limb amputations, and
death. The objective of this 200 patient study is to determine if a new blood thinner called
rivaroxaban (Xarelto) can be used to treat HIT. Rivaroxaban can be taken by mouth, does not
require blood testing, and had a low risk of bleeding when it was used to treat blood clots
in other clinical trials. If this study shows that rivaroxaban can be used to treat HIT,
there will be two very important benefits. For patients with HIT, the benefit will be having
a safe, and easy-to-use drug to protect them from developing further life or
limb-threatening blood clots. For the Canadian health care system, the benefit will be
having a drug that is much less expensive than the drugs currently used to treat HIT.
