Abstract:
Warfarin, a commonly used oral anticoagulant, is associated with several adverse drug reactions, principally bleeding. Of all hemorrhagic complications from warfarin therapy, thoracic hemorrhage accounts for only 3% and is usually related to trauma. Cases of spontaneous hemothorax secondary to anticoagulation therapy are rarely reported in the literature.
