Thousands of patients have complained of Xarelto side effects since the anticoagulant was approved in 2011, including pulmonary embolism, which the drug is sometimes administered to prevent. Pulmonary embolism occurs when an artery in the lung is suddenly blocked, often by a blood clot.
Symptoms of pulmonary embolism include a sudden shortness of breath, sharp chest pain and blood in mucus related to a cough. Blood clots that cause pulmonary embolisms often start in the leg and travel to the lungs. If the blood clot traveling to the lung is large enough, the pulmonary embolism can result in death.
Xarelto side effects such as pulmonary embolism have caused the U.S. Food and Drug Administration to order more clinical research to determine the efficacy and risks of the drug. Patients have complained of potentially fatal Xarelto complications such as pulmonary embolism, deep vein thrombosis, and internal hemorrhaging.
