Blood Irradiation Therapy and Tocilizumab

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

Moderate

IMMUNOSUPPRESSANTS

Why this applies to Tocilizumab

Tocilizumab falls under IMMUNOSUPPRESSANTS — the group Blood Irradiation Therapy interacts with.

Clinical research suggests that blood irradiation therapy may stimulate immune function in some patients. Theoretically, concurrent use of blood irradiation therapy might interfere with immunosuppressive therapy.
Immunosuppressant drugs include azathioprine (Imuran), basiliximab (Simulect), cyclosporine (Neoral, Sandimmune), daclizumab (Zenapax), muromonab-CD3 (OKT3, Orthoclone OKT3), mycophenolate (CellCept), tacrolimus (FK506, Prograf), sirolimus (Rapamune), prednisone (Deltasone, Orasone), and other corticosteroids (glucocorticoids).
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 gist with tocilizumab (Actemra): this drug is a biologic that quiets down an overactive immune system to calm conditions like rheumatoid arthritis or giant cell arteritis. Blood irradiation therapy, on the other hand, is thought to stimulate immune activity. So in theory, the two could work against each other, and the light therapy might blunt some of the calming effect you're getting from your tocilizumab. If that happened, you might notice your joint pain, stiffness, or swelling creeping back.

I want to be honest, though: this is a theoretical concern based on how each one works, not solid clinical proof. Tocilizumab isn't a prodrug, so this isn't about how it's broken down. Before trying blood irradiation, please run it by your rheumatologist or pharmacist first.

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 Tocilizumab Injection

What Is Tocilizumab Injection Used For?

Brand name: Actemra

Tocilizumab injection is used to treat several serious inflammatory and immune-related conditions. Actemra (tocilizumab) is indicated for moderately to severely active rheumatoid arthritis in adults who haven't responded well to other disease-modifying drugs, giant cell arteritis in adults, systemic sclerosis-associated interstitial lung disease (SSc-ILD) to slow lung function decline, polyarticular and systemic juvenile idiopathic arthritis in patients 2 years and older, and severe or life-threatening cytokine release syndrome (CRS) caused by CAR T-cell therapy in adults and children 2 and older.

Actemra is also approved for hospitalized adults and children aged 2 and older with COVID-19 who are on corticosteroids and need supplemental oxygen or mechanical breathing support. Not every brand or route is approved for every use — your prescriber will choose the right form for your specific condition.
