Blood Irradiation Therapy and Rivaroxaban

Here is the interaction we found between these two, with the evidence behind it.

Moderate

ANTICOAGULANT/ANTIPLATELET DRUGS

Why this applies to Rivaroxaban

Rivaroxaban falls under ANTICOAGULANT/ANTIPLATELET DRUGS — the group Blood Irradiation Therapy interacts with.

Preliminary clinical research suggests that blood irradiation therapy might reduce platelet aggregation. Case reports also suggest that blood irradiation therapy may be associated with an increased risk of nasal bleeding. Theoretically, blood irradiation therapy might increase the risk of bleeding when used concomitantly with anticoagulant/antiplatelet drugs.
Some of these drugs include aspirin, clopidogrel (Plavix), nonsteroidal anti-inflammatory drugs (NSAIDs) such as diclofenac (Voltaren, Cataflam, others), ibuprofen (Advil, Motrin, others), naproxen (Anaprox, Naprosyn, others), dalteparin (Fragmin), enoxaparin (Lovenox), heparin, warfarin (Coumadin), and others.
Severity Moderate Likelihood Possible Evidence D

Interaction has been documented in animal or in lab research, or the interaction has been documented in humans but is limited to case reports or conflicting clinical research exists.

Dr. Brian Staiger, PharmD, BCPS
Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Here's the simple version: rivaroxaban (Xarelto) already works by thinning your blood to stop dangerous clots. The concern is that blood irradiation therapy may, on its own, make your platelets a little less sticky, and a few case reports have linked it to things like nosebleeds. Stack those two together, and you could tip the balance toward too much bleeding.

I want to be honest about the evidence here, though. This is a theoretical worry based on how each one behaves, not something proven in solid studies. Still, with a blood thinner I'd rather you be cautious. Watch for easy bruising, nosebleeds that won't quit, pink or red urine, dark stools, or unusual gum bleeding. Before combining these, please run it by your doctor or pharmacist first.

From our pharmacist’s overview on the Rivaroxaban page

“Grapefruit is the interaction I would flag first for anyone taking rivaroxaban (Xarelto). It slows how the body clears this blood thinner, and higher levels mean more bleeding risk.”

About Blood Irradiation Therapy

What is Blood Irradiation Therapy?

  • Chronic infections
  • Immune support
  • Fatigue and general wellness
  • Inflammatory conditions
  • Circulatory complaints

Blood Irradiation Therapy is a medical procedure—not a dietary supplement or herb—in which blood is exposed to ultraviolet or laser light, either outside the body and re-infused or by an intravenous light device. It is not approved by the U.S. FDA for treating any disease, and high-quality evidence supporting modern claims is very limited. If you are considering it, talk with a qualified physician and treat any clinic marketing it for serious illness with strong caution.

About Rivaroxaban

What Is Rivaroxaban Used For?

Brand name: Xarelto

Rivaroxaban helps prevent and treat harmful blood clots. Across products, adults use it to lower stroke risk in nonvalvular atrial fibrillation, treat deep vein thrombosis (DVT) and pulmonary embolism (PE), and lower the chance those clots come back.

Rivaroxaban tablets are also used to prevent DVT after hip or knee replacement surgery and to prevent venous thromboembolism (VTE) in acutely ill medical patients. With aspirin, they reduce major cardiovascular events in coronary artery disease (CAD) and major thrombotic vascular events in peripheral artery disease (PAD). Children use it too: rivaroxaban for oral suspension (and Xarelto and Rivaroxaban tablets) is for VTE treatment and recurrence prevention from birth to under 18 years, and for clot prevention in children 2 and older with congenital heart disease after the Fontan procedure.
