My Guide to Coumadin ®/warfarin Therapy Information Notebook provided by the Community Anticoagulation Therapy Clinic (CAT Clinic) 319-558-4046 I appreciate the article as this issue is not well covered. However, and with all due respect, I think the absolute conclusion “While you are taking blood thinners you should not dive” is neither supported by the science nor responsible without any information as to a particular diver’s circumstances. PULMONARY EMBOLISM OVERVIEW. Pulmonary embolism (PE) occurs when a blood clot (thrombus) dislodges from a vein, travels through the bloodstream, and lodges in the lung (where it is called a pulmonary embolus ). DESCRIPTION. COUMADIN (warfarin sodium) tablets and COUMADIN (warfarin sodium) for injection contain warfarin sodium, an anticoagulant that acts by inhibiting vitamin K⌈dependent coagulation factors.

Pulmonary embolism occurs when there is a deep vein thrombosis in which there is a blood clot. The blood clot travels up into the lungs. Eliquis (apixaban) and Coumadin (warfarin) are anticoagulants (blood thinners) used to reduce blood clotting and reduce the risk of stroke, heart attack, and systemic embolism in patients with nonvalvular atrial fibrillation. Coumadin ® is indicated for: • Prophylaxis and treatment of venous thrombosis and its extension, pulmonary embolism (PE). • Prophylaxis and treatment of thromboembolic complications associated with atrial fibrillation (AF) and/or cardiac valve replacement.
