What is Xarelto?

You may have seen the commercials on TV featuring celebrities golfing and talking about the benefits of Xarelto. What they do not mention is that Xarelto is not the safest drug on the market and is the target of thousands of lawsuits over its intense and potentially life-threatening side-effects.

Xarelto (rivaroxaban) is an anticoagulant medication developed by Bayer Pharmaceuticals and Janssen Pharmaceuticals. Xarelto is marketed in the United States by Janssen Pharmaceuticals. Xarelto thins the blood to avoid developing blood clots. It was first approved for use by Health Canada and the European Commission and in 2011, the FDA approved it for use in the U.S. However, the FDA first recommended against approving Xarelto for use in patients with Atrial fibrillation, or AFIB, due to safety concerns and poor performance compared to Warfarin in a major clinical trial. In fact, each of Xarelto’s clinical trials was the subject of major concern at the FDA. The result of one clinical trial, known as RECORD 4, was rejected by the FDA.

Before Xarelto, Warfarin (also called Coumadin) was the gold standard for preventing blood clots and had been since the early 1950’s. However, Warfarin is considered difficult to use because of dietary restrictions and regular laboratory testing, even though it has been the gold standard for decades. Xarelto is marketed as easier for patients to use because unlike Warfarin, there are no dietary restrictions or regular laboratory testing associated with its use.

What Does Xarelto Treat?

Xarelto is indicated for blood clot treatment and prevention for DVT (Deep Vein Thrombosis), which is a condition where blood clots form in major vessels, typically in the arms and legs. A DVT can travel through the body and settle in the lungs, causing a blockage of blood flow. This condition is called a pulmonary embolism.

Xarelto is also used to prevent blood clots in people who have an abnormal heart rhythm disorder called AFIB. AFIB develops when the upper chambers of the heart beat very rapidly and irregularly, resulting in blood being pumped inefficiently to the rest of the body. The inefficient pumping can cause blood clots to form, which can cause a stroke or a heart attack.


How Does Xarelto Work?

Xarelto targets a specific blood coagulation factor, Factor Xa, and stops it from aiding in the development of clots. By interfering with the action of Factor Xa, Xarelto prevents a major step of the chain reaction needed to form a blood clot.

How is Xarelto Different?

Xarelto’s biggest competitor is Warfarin. Warfarin is a blood thinning medication that was introduced in the 1950’s. One highly-advertised advantage of Xarelto is that, unlike Warfarin, it does not require regular blood monitoring. Xarelto is prescribed with a standard dose and Warfarin requires blood tests to determine the correct dosage. Another major difference between Xarelto and Warfarin is that Warfarin has an antidote, Vitamin K, which can be administered to patients that develop bleeding because their blood is too “thin.” There is no antidote for Xarelto.

Other drugs, similar to Xarelto have been shown to be more effective and safer, leading some healthcare professionals to question whether there is a medical need for Xarelto.

What are the Side Effects of Xarelto

IMPORTANT: This page is for informational purposes only – if you are experiencing a medical emergency, contact a healthcare professional or dial 911 immediately.


The side effects of Xarelto are a serious problem and the reason that it has been subject to so many recent lawsuits. The most common side effects are relatively minor, such as:

  • Back pain
  • Nosebleeds
  • Headaches
  • Dizziness
  • Difficulty swallowing or breathing
  • Bleeding gums
  • Digestion changes

The major side effects are more worrisome because Xarelto does not have an antidote. Excessive bleeding, whether it is internal or external, can be fatal in patients taking Xarelto. Signs of excessive bleeding problems include:

  • Strange bruising
  • Severe headaches or dizziness
  • Vision changes
  • Weakness
  • Vomiting blood
  • Heavy menstrual bleeding
  • Heavy nosebleeds
  • Swelling

Can you stop bleeding while on Xarelto

If a person taking Xarelto develops a bleeding problem and it is caught quickly, healthcare professionals may be able to stop the bleeding simply by stopping the medication. Once a patient has not taken Xarelto for 24 hours, his or her body will naturally begin to remove the drug. This should stop the bleeding.

However, if internal bleeding occurs and there are no obvious signs of the bleeding, the patient may experience fatal consequences.

Bleeding from Xarelto is a serious problem and without regular blood testing and interaction with doctors, patients taking the drug are often at a higher risk for developing severe bleeding.

What Are Xarelto Lawuits?

Many patients are filing lawsuits against the manufacturers of Xarelto because they suffered injuries from excessive bleeding. Hundreds of patients have lost their lives due to uncontrolled bleeding.

In general, people file lawsuits like these because the effects caused financial and emotional stress on the patient or the patient’s family. They are attempting to recover financial compensation for their injuries from the company that manufactured the drug – in this case, Janssen Pharmaceuticals and Bayer Pharmaceuticals.

Many patients have also reported the development of blood clots while taking Xarelto, which is exactly what it is supposed to prevent. These blood clots have led to DVT, pulmonary embolism, strokes, and heart attacks.
