A dozen Xarelto lawsuits were filed in a California federal court on March 16, 2015, Law360 reported.

The plaintiffs claim that Johnson & Johnson’s (J&J) Janssen Pharmaceuticals unit and Bayer Corporation failed to warn about potential Xarelto problems that caused gastrointestinal bleeding.

One of the claimants suffered a stroke as a result of a Xarelto bleeding event.

Xarelto was marketed as a more convenient alternative to the anticoagulant warfarin, which required patients to undergo routine blood level monitoring.  The  manufacturers failed to warn patients to monitor blood levels to determine if they were at risk of internal bleeding.

Xarelto users should alert their doctor if they experience:

  • Frequent nose bleeds
  • Unusual gum bleeding
  • Unusually heavy menstrual bleeding or vaginal bleeding
  • Red, pink or brown urine
  • Red or black stool
  • Coughing up blood or blood clots
  • Vomiting blood or what looks like coffee grounds
  • Headaches, dizziness or weakness
  • Pain, swelling or new drainage at wound sites


In the complaint, Xarelto attorneys question whether J&J and Bayer wrongly told health care providers that follow-up blood testing was not necessary for patients taking Xarelto, Law360 reported.

About 130,000 Xarelto prescriptions were written in the U.S. during the first quarter of 2012, according to an article in the Huffington Post.
