Lawsuits have been filed in state and federal court by plaintiffs who suffered serious internal bleeding after taking Xarelto. The anti-clotting drug is manufactured by the German drug giant Bayer. Xarelto is distributed in the U.S. by Johnson & Johnson subsidiary Janssen Pharmaceuticals.
Xarelto is a blood thinner. The anti-clotting drug is one of Bayer’s top five medicines and it earned $1.3 billion in sales last year.
The lawsuits charge that the companies failed to warn users that Xarelto could result in irreversible internal bleeding. Xarelto has been marketed as a more convenient choice than warfarin (Coumadin), which is used as an anticoagulant in the U.S. since the 1950s. Warfarin requires patients to take frequent blood tests and follow a strict diet. However, warfarin’s anticoagulation is reversible by administering Vitamin K. Xarelto does not have a known reversal agent and many of the serious bleeding incidents have led to death.
