Interação entre Heparina e Rivaroxabana

Acute PE in Hemodynamically Unstable Patients or Patients Who Require Thrombolysis or Pulmonary Embolectomy Initiation of XARELTO is not recommended acutely as an alternative to unfractionated heparin in patients with pulmonary embolism who present with hemodynamic instability or who may receive thrombolysis or pulmonary embolectomy.

If anticoagulation with XARELTO is discontinued for a reason other than pathological bleeding or completion of a course of therapy, consider coverage with another anticoagulant [see Dosage and Administration (2.3 , 2.4) , Warnings and Precautions (5.1) , and Clinical Studies (14.1) ] .

…• 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 • optimal timing between the administration of XARELTO…

To reduce this risk, consider coverage with another anticoagulant if XARELTO is discontinued for a reason other than pathological bleeding or completion of a course of therapy.

Avoid concurrent use of XARELTO with other anticoagulants due to increased bleeding risk unless benefit outweighs risk.

Avoid use of heparin after use of andexanet alfa for the reversal of direct Factor Xa inhibitors (apixaban and rivaroxaban).

Unresponsiveness to Heparin with Concomitant Use With Andexanet Alfa Unresponsiveness to unfractionated heparin leading to non-prolongation of activated clotting times and serious thrombotic events has occurred when unfractionated heparin was administered after use of andexanet alfa for the reversal of direct Factor Xa inhibitors (apixaban and rivaroxaban).
