IV Ozone Therapy: What It Is, Whether It Is Safe, and What It Costs

IV ozone therapy is an alternative treatment in which a small volume of your blood is drawn, mixed with medical-grade ozone gas outside the body, and then returned to your bloodstream. The standard method is called major autohemotherapy, or MAH, and it typically uses 100 to 200 mL of blood in a session lasting 30 to 60 minutes.

It is worth saying at the outset what most pages selling this treatment leave out. Ozone therapy is not approved by the FDA, the clinical evidence is limited, and one specific version of the procedure carries a serious risk. You should understand all three before you decide anything.

What Is IV Ozone Therapy?

Ozone is a gas made of three oxygen atoms. Medical-grade ozone is produced from pure oxygen using a generator, and it is not the same as the ozone in smog, which is a pollutant produced by very different chemistry.

There are three ways ozone gets into the bloodstream, and the differences matter more than most clinics explain:

• Major autohemotherapy (MAH). The common method. Blood is drawn into a sterile container, ozone is added and mixed, and the ozonated blood is reinfused through the same IV line. The gas reacts with the blood outside your body.
• EBOO (extracorporeal blood ozonation and oxygenation). Blood is circulated through a filter and ozonated continuously before returning, closer to a dialysis setup. It processes a much larger blood volume than MAH.
• Direct intravenous ozone injection. Ozone gas pushed straight into a vein. This is the version that has produced reported cases of gas embolism, and it is not what a reputable clinic does.

When a news story or a case report describes someone seriously harmed by ozone therapy, it is usually worth checking which of those three was performed. That detail is often missing from the coverage and it changes the risk picture substantially.

Is IV Ozone Therapy FDA Approved?

No. The FDA has not approved ozone for any medical use, and its position is stronger than simple absence of approval. Federal regulation 21 CFR 801.415 states that ozone is a toxic gas with no known useful medical application in specific, adjunctive, or preventive therapy.

Ozone therapy is offered in the United States as an alternative or complementary treatment, outside the FDA approval pathway. Cleveland Clinic and WebMD both describe it the same way. Any clinic that tells you ozone therapy is FDA approved is either mistaken or misleading you, and that alone is a reason to look elsewhere.

Not being FDA approved does not automatically mean a treatment does nothing. It does mean nobody has run the large, controlled trials that approval requires, so the honest position is uncertainty rather than confidence.

Is IV Ozone Therapy Safe?

The risks are real and they are worth stating plainly rather than burying under a list of benefits.

Gas embolism. Injecting ozone gas directly into a vein can introduce a gas bubble into the circulation, which can travel to the lungs or brain. A 2025 case report published through the NIH describes a neurological crisis following intravenous ozone therapy. This is the most serious documented risk, and it is specific to direct gas injection rather than to ozonating blood outside the body.

Lung irritation. Ozone is genuinely toxic to lung tissue when inhaled. Medical ozone is never given by breathing it in, and a clinic that does not treat that as an absolute rule is not one to trust.

Common milder effects. Some patients report headache, lightheadedness, nausea, fatigue for a day, or discomfort at the IV site. These are usually short-lived.

Who should not have it. Ozone therapy is not appropriate for people with G6PD deficiency, a condition in which red blood cells break down under oxidative stress. It is also generally avoided in pregnancy, in people with hyperthyroidism, in people with bleeding disorders or on anticoagulants, and after a recent heart attack. Screening for these is the reason a provider has to review your history first.

What Does the Research Actually Show?

Mixed, and thinner than the marketing suggests.

The proposed mechanism has a reasonable basis. Ozone reacting with blood produces short-lived compounds that appear to trigger a mild oxidative response, which in theory nudges the body's own antioxidant systems into action. Laboratory and animal work supports parts of that picture.

The human evidence is where it thins out. A 2023 evidence gap map published through the NIH catalogued ozone research across pain, infection, inflammation, and wound healing, and found the strongest signals in dental and orthopedic applications delivered locally rather than intravenously. Most published studies are small, many lack a control group, and much of the literature comes from a handful of countries where ozone therapy is already an established part of practice.

What that adds up to: a treatment with a plausible mechanism, some encouraging small studies, and no large controlled trial establishing that it works for the chronic conditions it is most often sold for. Anyone presenting it as proven is ahead of the data.

What Do People Use IV Ozone Therapy For?

Framing matters here, so this section describes what patients and practitioners use it for, not what it is proven to treat.

• Chronic infections. Chronic Lyme disease and persistent viral infections are the most common reasons patients ask us about it. Some patients describe meaningful improvement alongside their primary treatment. Ozone is not a substitute for antimicrobial therapy.
• Immune support. Used by patients looking to modulate immune function, often in the context of an autoimmune condition. Evidence here is early.
• Fatigue and recovery. Frequently reported subjectively. Subjective improvement is real to the person experiencing it and is also the outcome most vulnerable to placebo, which is worth holding in mind.
• Inflammation. The oxidative-response mechanism above is the rationale. The clinical evidence in humans is limited.

We do not present ozone therapy as a treatment for cardiovascular disease, cancer, or any condition where delaying established care could cause harm. If you read that claim on another clinic's site, treat it as a warning sign.

What Happens During an IV Ozone Therapy Session?

A typical MAH session runs 30 to 60 minutes. An IV line is placed, roughly 100 to 200 mL of blood is drawn into a sterile container, medical-grade ozone at a set concentration is introduced and gently mixed, and the ozonated blood is returned through the same line. You sit in a chair throughout and most people read or work.

Some patients notice a mild lightheaded feeling during the reinfusion. Most return to normal activity immediately afterward. Concentration and volume are set by your provider rather than being fixed, because both are dose decisions.

How Much Does IV Ozone Therapy Cost?

Cost depends on the method used, the number of sessions, and whether ozone is a standalone treatment or part of a broader plan, so we quote it directly rather than publishing a single number that would be wrong for most people.

What we can tell you up front is the structure at Med Matrix. New patients begin with testing and consultation, which runs approximately $1,200 to $1,500 and includes the 80+ biomarker panel, the InBody 770 body composition scan, and a full 60-minute provider consultation. Follow-up visits are $275. We are cash-pay and accept HSA, FSA, and CareCredit. Insurance does not cover ozone therapy, because it is not an FDA-approved treatment. Call (207) 544-4643 for current session pricing, and new patients receive a $100 voucher toward the first visit.

How We Approach Ozone Therapy at Med Matrix

Ozone is one option inside a functional medicine practice, not the centerpiece of one. Before we discuss it with anyone, we run a panel of 80+ biomarkers and sit down for a full hour to go through the results, because the most common outcome of that conversation is finding something more actionable than ozone. Thyroid dysfunction, iron deficiency, and unaddressed inflammation all produce the fatigue that sends people looking for alternative treatments in the first place.

When ozone does fit, we screen for the contraindications above, we use major autohemotherapy rather than direct gas injection, and we tell patients honestly where the evidence stands. Patients pursuing it most often do so alongside Lyme disease treatment or a broader functional medicine plan. You can also read how we handle IV nutrient therapy, which is a different treatment with a different evidence base, and one patient's account of using ozone alongside Lyme treatment.

Frequently Asked Questions

Is IV ozone therapy FDA approved?

No. The FDA has not approved ozone for any medical use, and 21 CFR 801.415 describes ozone as a toxic gas with no known useful medical application in specific, adjunctive, or preventive therapy. It is offered in the United States as an alternative treatment outside the approval pathway, which is why insurance does not cover it and why provider screening matters.

How much does ozone IV therapy cost?

Pricing varies by method and by how many sessions are involved, so we quote it directly. New-patient testing and consultation at Med Matrix runs approximately $1,200 to $1,500, which covers the 80+ biomarker panel, the InBody 770 scan, and a 60-minute provider consultation. Follow-ups are $275. Insurance does not reimburse ozone therapy. Call (207) 544-4643 for current session pricing.

What are the risks of IV ozone therapy?

The most serious documented risk is gas embolism from injecting ozone gas directly into a vein, which is why major autohemotherapy ozonates blood outside the body instead. Inhaled ozone is toxic to lung tissue and is never part of treatment. Milder reported effects include headache, lightheadedness, nausea, and short-term fatigue. It is avoided in G6PD deficiency, pregnancy, hyperthyroidism, bleeding disorders, and after a recent heart attack.

How often should you do ozone IV therapy?

There is no established schedule, because there is no large trial defining one. In practice patients often start with a short series of weekly or twice-weekly sessions and then move to a longer interval based on how they respond. Frequency should be set by a provider who is tracking your labs and symptoms, not by a package purchased in advance.

Is ozone therapy the same as IV vitamin therapy?

No. IV nutrient therapy delivers vitamins, minerals, and amino acids into the bloodstream to correct deficiencies, and correcting a documented deficiency has solid evidence behind it. Ozone therapy does not deliver nutrients at all; it exposes your blood to a reactive gas to provoke a mild oxidative response. Different mechanism, different evidence base, different risk profile.

Does ozone therapy cure Lyme disease?

No, and any clinic claiming otherwise is overstating what is known. Some patients with chronic Lyme symptoms report feeling better using ozone alongside their primary treatment, and that experience is worth taking seriously, but there is no controlled evidence that ozone eradicates the infection. It should be considered supportive, never a replacement for antimicrobial treatment prescribed by a provider.

Get an Honest Answer Before You Commit

Most people asking about ozone therapy are exhausted, have been told their labs are normal, and are looking for something that finally works. That is a reasonable place to be. It is also the moment when an alternative treatment is easiest to oversell.
