Ozone Therapy and Fibromyalgia: What the Research Shows (2026 Update)

If you live with fibromyalgia, you already know the pattern. Pain that moves around the body. Sleep that never feels deep. A tiredness that rest does not fix. And often, years of appointments before anyone gave it a name.

You also know that standard treatment helps some people and leaves many others still searching. That gap is why researchers have been studying ozone therapy as a complementary approach - something used alongside standard care, not instead of it.

Since 2022, nine new clinical studies have been published, and in 2026 a Swiss internal medicine specialist, Dr Raffaella Craighero, pulled them together in a review for the Ozone Therapy Global Journal. We have read the review and the studies behind it. This page sets out what they found, what is still uncertain, and how people use ozone therapy at home.

Fibromyalgia in plain words

Fibromyalgia affects about 2.7% of people worldwide. Women are diagnosed roughly twice as often as men, and it becomes more common with age.

The core features are widespread muscle and soft-tissue pain lasting more than three months, poor deep sleep with frequent waking, fatigue, and the concentration and memory trouble many people call "fibro fog". Headaches, irritable bowel symptoms, restless legs and sensitivity to touch, light and chemicals are common companions.

There is no blood test or scan for fibromyalgia. Diagnosis rests on symptoms and on ruling other conditions out, which is why it can take up to two years from the first symptoms.

Why researchers looked at ozone

Fibromyalgia is now understood as a disorder of pain processing. The nervous system turns the volume up on pain signals, a process called central sensitisation. Research over the past decade has added three more pieces:

• Oxidative stress. People with fibromyalgia tend to show an imbalance between damaging reactive oxygen species and the body's antioxidant defences.
• Low-grade inflammation. Studies find higher levels of inflammatory messengers and lower levels of anti-inflammatory ones. Inflammation and pain appear to feed each other in a loop.
• Cellular energy. Mitochondria, the energy producers in each cell, appear to work less efficiently, which may help explain the fatigue.

Medical ozone, given in small controlled doses, acts as a brief, mild oxidative signal. The body responds by switching on its own antioxidant and anti-inflammatory defences through a pathway called Nrf2. It is the same principle as exercise: a small, measured stress that prompts the body to adapt. You can read more about this in Ozone Preconditioning: Waking up the dragon.

Because those mechanisms line up with what goes wrong in fibromyalgia, researchers set out to test whether people actually feel better.

What the studies found

Ozone therapy for fibromyalgia was first used in Germany in 1993. The published research now spans more than a decade and well over 600 patients. The pattern across it is consistent: less pain, better sleep, less fatigue and better day-to-day function.

Three practical patterns run through these studies:

• Everyone started low. Protocols began at a gentle ozone concentration and stepped up over the course.
• A course was about ten sessions, usually twice a week, and benefit typically showed from around the fifth session.
• Top-ups mattered. Where treatment stopped, some symptoms crept back by six months. In the one study that continued with a monthly session, the improvement held for a full year.

The honest picture

We think you should know the limits as well as the results.

Most of these studies had no comparison group, and fibromyalgia is known to respond to placebo. The one randomised, double-blind trial (Sucuoğlu 2023) is therefore the most informative. In it, people receiving ozone did significantly better than the placebo group on sleep quality, fatigue and feeling well. On the overall fibromyalgia score, both groups improved and the gap between them was not statistically significant.

Not everyone responds, either. In the largest study, roughly one person in six saw no improvement.

Dr Craighero's conclusion is a fair one: ozone therapy is a promising, low-cost complementary approach with few side effects, particularly for people whose symptoms persist despite standard care - and larger controlled trials are still needed. The ISCO3 guideline on fibromyalgia reaches the same view.

Clinic treatment and home treatment: two doors into the same room

Most of the studies above used major autohaemotherapy (MAHT). A clinician draws about 100 mL of your blood, mixes it with ozone and returns it through a drip. It works, but it needs a clinic, a needle and a practitioner every time - and in New Zealand only a handful of practitioners offer it, most of them in the upper North Island.

The other systemic route is rectal insufflation (RI): a small, measured volume of ozone gas introduced through a soft catheter. It takes a few minutes, needs no needle, and can be done privately at home.

Here is the part many people do not realise. In neither route does ozone itself travel around your body. Ozone reacts within seconds with the first thing it touches - the blood in the bag during MAHT, or the moist lining of the bowel during RI. That reaction produces the same short-lived messenger molecules, and it is those messengers that circulate and switch on the body's antioxidant and anti-inflammatory response. The Madrid Declaration describes it this way: with RI, the reaction products "penetrate the mucosa and enter the circulation of venous and lymphatic capillaries". Different door, same room.

The evidence that the two routes are comparable:

• The international standard treats RI as a full systemic route. The Madrid Declaration on Ozone Therapy (4th edition, 2025) describes rectal insufflation as "a systemic route" that "is generally well tolerated and allows scalability to doses similar to those used for MAH", and notes it can be used safely in children, older people and anyone with difficult veins.
• The largest evaluation found comparable results. Viebahn-Hänsler and colleagues (2016) assessed more than 11,000 MAHT treatments in 577 patients and more than 47,000 RI treatments in 716 patients. Both routes were classed as effective and safe across chronic inflammatory and circulatory conditions, with RI achieving results comparable to MAHT. Read our summary: Rectal Insufflation vs Major Autohaemotherapy.
• RI has been studied in fibromyalgia directly. In the Hidalgo-Tallón pilot study, 24 RI sessions over 12 weeks brought a significant fall in fibromyalgia impact scores, with improvements in physical symptoms and mood. In the Tirelli 2019 study, 55 patients received MAHT and 10 received RI, and 70% of the whole group improved by more than half.
• The ISCO3 fibromyalgia guideline lists RI alongside MAHT as a recommended route, and the Madrid Declaration names fibromyalgia among the conditions where ozone therapy has been used with the support of clinical trials - citing the RI pilot study among its evidence.

No trial has yet compared the two routes head to head in fibromyalgia specifically. What the wider evidence shows is that RI delivers a comparable systemic effect to MAHT, with three practical advantages: no needles, a fraction of the cost per session, and the freedom to follow a full course - and the monthly top-ups that seem to matter - in your own home.

What one of our customers told us

The most rewarding part of our work is hearing from people after they have been using ozone for a while. This message came from a customer who uses vaginal insufflation (VI). The Madrid Declaration classes VI as a systemic route too, and rates it as more effective than either MAHT or RI:

★★★★★

"Ozone therapy is remarkable! I have struggled with constant pain from fibromyalgia for over 20 years. Since discovering ozone therapy, I am now sleeping at night. It is a life changer. I am still using VI every 2 to 3 days. I am hoping that eventually I will be able to reduce the frequency."

It is one person's experience, and yours may differ. We share it because it echoes what the trials keep finding: sleep is often the first thing to change.

How people approach it at home

The home approach follows the same shape as the clinical studies:

• Start low and go slow. Begin at a gentle concentration and build up over the first weeks, exactly as the study protocols did.
• Work in courses. The Madrid Declaration describes a cycle as 20 sessions, repeated every three to four months during the first year - rather than the same routine indefinitely.
• Give it time. In the studies, change typically showed from around the fifth session, and sleep often improved before pain did.
• Keep your usual care going. Every study used ozone alongside standard treatment, not in place of it.

A home setup is an ozone generator, an oxygen source and the insufflation accessories, with a protocol handbook and video guides to walk you through it. If you would like to see what is involved, our home ozone therapy bundles page lays out the options, and the rectal insufflation video guide shows the whole process from start to finish.

Who should not use ozone therapy

Ozone therapy is not suitable for everyone. The Madrid Declaration lists these contraindications for systemic ozone: G6PD deficiency (favism), uncontrolled hyperthyroidism (Graves' disease), a very low platelet count or a severe clotting disorder, severe cardiovascular instability, a recent heart attack, acute heavy bleeding, seizure states, haemochromatosis, acute alcohol intoxication, and current intravenous iron or copper treatment. It should also be avoided in the first trimester of pregnancy. Ozone gas must never be breathed in. If you take blood-thinning medication or are managing a serious condition, talk to your healthcare practitioner first.

We follow the guidelines of the International Scientific Committee of Ozone Therapy (ISCO3) and the Madrid Declaration on Ozone Therapy. Ozone therapy is a complementary approach. It is not a cure for fibromyalgia, and it does not replace the care of your doctor.
