When Xarelto Rivaroxaban was approved by the FDA in 2011, the side effects listed on the warning labels were somewhat realistic. Xarelto was touted as a "one-dose-fits-all" medication that would eliminate all of the annoyances that both patients and doctors had to live with. The actual side effects that patients were experiencing are scary.
The industry standard anticoagulant Warfarin requires regular blood testing and dietary restrictions to maintain the effectiveness of the drug. Depending on the results of the blood work, the dosage would have to be adjusted for the drug to remain effective and also be safe for the patient as well.
Anticoagulants do carry a risk when you use them. The main risk with an anticoagulant is bleeding. However, Xarelto lawsuits already filed, are alleging that the potentially deadly side effects were minimized.
