Drug & supplement interaction

Blood Irradiation Therapy + Carbidopa

Carbidopa brand name: Lodosyn.

No Known Interaction

Medically reviewed by Dr. Brian Staiger, PharmD, BCPS · Updated July 2026 · Pair last verified Oct 4, 2026

The bottom line No known interaction

We found no known interaction between Blood Irradiation Therapy and Carbidopa in our sources. Absence of a documented interaction is not the same as proven safety, and does not guarantee one does not exist. Do not start, stop, or change a medication or supplement based on this page; confirm with your pharmacist or doctor first. Additionally, although there is no interaction, the two are separately associated with some of the same side effects, which would make a new symptom harder to attribute to one or the other.

Interaction report

Blood Irradiation Therapy and Carbidopa

We checked these two against our interaction database. Here is what we found.

No Known Interaction Found

We did not find a documented interaction between Carbidopa and Blood Irradiation Therapy in our sources. This does not guarantee that the combination is completely free of risk — research on Blood Irradiation Therapy alongside specific medications may be limited.

Blood Irradiation Therapy is a treatment rather than something you take. Tell whoever provides it which medicines you use, and ask your prescriber whether it is appropriate for your health and treatment. Do not stop a prescribed medicine on your own.

Always talk with your pharmacist or doctor before making changes to your medications or supplements, particularly if you take several medications or have an ongoing health condition.

Blood Irradiation Therapy safety at a glance

Blood Irradiation... overall Use caution This is an invasive procedure with infection and other risks, and it is not a proven treatment for most conditions.

Pregnancy Avoid Safety during pregnancy has not been established, so it is best avoided.

Breastfeeding Avoid There is no reliable safety data during breastfeeding, so avoid it.

Safety guidance is general; always confirm with your pharmacist or doctor for your situation.

How we checked

Why No Interaction Is Listed for Carbidopa

Interactions in our licensed database are recorded against drug classes, not just single drug names. Carbidopa is filed under 3 classifications — including oral drugs. Blood Irradiation Therapy has documented interactions with 3 drug classes — the most serious being anticoagulant/antiplatelet drugs (moderate), antidiabetes drugs (moderate) and immunosuppressants (moderate) — and none of Carbidopa’s classifications are among them.

Classification data comes from our licensed Natural Medicines dataset. A medication can belong to classes beyond those recorded there, so this describes how the check was run — it is not a safety guarantee.

What to actually watch for

No Interaction Found — But Data Suggests Blood Irradiation Therapy and Carbidopa May Share Several of the Same Side Effects

This is not an interaction. Neither one changes how your body handles the other, and nothing here says they react together. What our sources do show is that each has separately been linked to the effects below — so having Blood Irradiation Therapy while taking the medicine can make those effects more likely to turn up, and harder to pin on one or the other if they do. 2 of them are worth acting on rather than waiting out — marked below.

Everything else you take

See Every Supplement That Interacts With Carbidopa

This page covers Blood Irradiation Therapy only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Carbidopa page lists 21 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Activated Charcoal (major), Magnesium (major), 5-htp (moderate), Coffee Charcoal (moderate) and European Mandrake (moderate).

By severity: 2 major · 10 moderate · 9 minor.

From our pharmacist’s overview on the Carbidopa page

“Carbidopa (Lodosyn) keeps levodopa working in Parkinson's disease, so anything that blocks its absorption can cost real motor control, and two of the 21 supplements on this list do exactly that at a level rated major. Magnesium is the one that surprises people: in a human study it cut carbidopa absorption by 81 percent and levodopa's b…”

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.

Whole blood (drawn and re-infused, or treated within the body) · Ultraviolet blood irradiation (UBI), intravenous laser blood irradiation, photodynamic procedures performed in clinics

An interaction check asks whether these two react with each other — it does not ask whether Blood Irradiation Therapy is a good idea for someone in your situation. Here is what our Blood Irradiation Therapy record says about it on its own.

Blood Irradiation Therapy: dosing

There is no standardized, scientifically established dose or protocol for Blood Irradiation Therapy. Clinics vary widely in the light source used, the amount of blood treated, the length of exposure, and how many sessions are recommended.Because this is a procedure rather than a pill or supplement, there is no label dose to follow.

About Carbidopa

What Is Carbidopa Used For?

Brand name: Lodosyn

Carbidopa (sold as Carbidopa tablets and as Lodosyn) is used together with carbidopa-levodopa or levodopa. It treats symptoms of idiopathic Parkinson’s disease, postencephalitic parkinsonism, and symptomatic parkinsonism that may follow nervous system injury from carbon monoxide or manganese poisoning.

It is used in two situations. One is when a person’s carbidopa-levodopa dose does not supply enough carbidopa. The other is when a person needs carbidopa and levodopa adjusted separately. It does not treat Parkinson’s symptoms when taken alone.

Having Blood Irradiation Therapy While Taking Carbidopa: Common Questions

Is it safe to have Blood Irradiation Therapy while taking Carbidopa?

We do not list a known interaction between Blood Irradiation Therapy and Carbidopa. That does not guarantee the combination is risk-free, so confirm with your pharmacist or doctor — especially if you take other medications or have a health condition.

Do Blood Irradiation Therapy and Carbidopa have any of the same side effects?

Yes — our sources link each of them separately to 3 of the same effects. That is not an interaction: neither changes how your body handles the other. It does mean that if one of those effects turns up, it can be harder to tell which one is behind it. They are listed on this page with the source behind each.

How was the Blood Irradiation Therapy and Carbidopa combination checked?

Interactions in our licensed database are recorded against drug classes. Carbidopa is filed under 3 classifications, and Blood Irradiation Therapy has documented interactions with 3 drug classes — none of Carbidopa's classifications are among them. A medication can belong to classes beyond those recorded in our dataset, so this describes how the check was run rather than guaranteeing safety.

Does Blood Irradiation Therapy interact with any other medications?

Yes. Blood Irradiation Therapy has 327 documented drug interactions in our database — Carbidopa is simply not one of them. If you take anything else, it is worth checking each one; they are all listed on this page.

Does Carbidopa interact with any supplements?

Yes. Carbidopa has documented interactions with 21 supplements in our database — Blood Irradiation Therapy is not one of them. The Carbidopa interaction page linked on this page lists every one, ranked by severity.
