I think there's a class action law suit in process for xarelto right now--there's ads on TV for anyone who has had a bad experience, or died, from using the drug. My daughter's father-in-law lost his battle when he was on it and it caused brain hemorrahages. But on the positive side, my son-in-law took it for 3 months after a surgical procedure on his knee when he developed some breathing problems. He's fine now and his doctors really wanted him to try it rather than one of the older drugs.
