When should a patient stop taking Multaq (dronedarone) before undergoing cardioversion for atrial flutter while being treated with Eliquis (apixaban)?

From the Guidelines

Multaq (dronedarone) should not be discontinued before cardioversion for a patient with atrial flutter who is already on Eliquis (apixaban). The patient should continue taking Multaq as prescribed through the cardioversion procedure. Multaq is an antiarrhythmic medication that helps maintain normal heart rhythm and is often used to reduce the risk of recurrence of atrial flutter after cardioversion. Stopping Multaq before cardioversion could potentially increase the risk of the patient returning to an irregular rhythm after the procedure. The patient should continue taking Eliquis as well, as it provides anticoagulation to prevent blood clots during and after cardioversion. After cardioversion, both medications should be continued as directed by the healthcare provider, with Multaq helping to maintain normal sinus rhythm and Eliquis preventing stroke risk.

Some key points to consider:

• The patient should be on anticoagulation therapy for at least 3 weeks before cardioversion, as recommended by the guidelines 1.
• The TEE-guided approach can be used as an alternative to the conventional approach of anticoagulation for 3 weeks before cardioversion, but it requires an experienced echocardiographer 1.
• The decision to continue or discontinue Multaq should be based on the individual patient's risk factors and medical history, and should be made in consultation with a cardiologist.
• The patient should be closely monitored for any signs of thromboembolism or other complications after cardioversion, and should seek medical attention immediately if any symptoms occur.

It is essential to prioritize the patient's safety and well-being, and to follow the guidelines and recommendations for anticoagulation therapy and cardioversion. By continuing Multaq and Eliquis as prescribed, the patient can minimize the risk of complications and achieve the best possible outcome.

From the FDA Drug Label

WARNINGS AND PRECAUTIONS Determine cardiac rhythm at least once every 3 months. If AF is detected discontinue MULTAQ or cardiovert (5.2). The patient should have stopped his Multaq before the cardioversion, as the drug label recommends discontinuing Multaq if AF is detected, or cardioverting 2.

• The exact timing of when to stop Multaq is not specified in the label, but it should be stopped before the cardioversion procedure.

From the Research

Stopping Multaq Before Cardioversion

• The patient has been taking Eliquis for over a few months and is still in atrial flutter, planning for cardioversion, and has picked up Multaq (dronedarone) 3.
• There is no direct evidence on when to stop Multaq before cardioversion, but studies suggest that dronedarone is used to reduce the risk of hospitalization in patients with paroxysmal or persistent atrial fibrillation or atrial flutter 3.
• The decision to stop Multaq before cardioversion may depend on the patient's individual risk factors and the type of anticoagulation therapy being used, such as Eliquis (apixaban) 4, 5, 6.
• Studies have shown that cardioversion can be safe without transesophageal echocardiography in patients treated with non-vitamin K antagonist oral anticoagulants, such as apixaban 5.
• The timing of stopping Multaq before cardioversion is not explicitly stated in the available evidence, but it is recommended to follow the guidance of a healthcare professional for personalized advice.

Anticoagulation Therapy and Cardioversion

• Anticoagulation therapy, such as Eliquis, is crucial in reducing the risk of thromboembolic events after cardioversion 4, 5, 6.
• The duration of anticoagulation therapy before and after cardioversion depends on the patient's individual risk factors and the type of anticoagulation therapy being used 4, 5, 6.
• Studies have shown that a brief anticoagulation therapy using low-molecular-weight heparins can be safe and feasible in patients undergoing cardioversion 4.
• The decision to stop or continue anticoagulation therapy before cardioversion should be made in consultation with a healthcare professional, taking into account the patient's individual risk factors and medical history 4, 5, 6, 7.
