Severity — How Serious It Can Be

  • Major. Clinically significant; generally best avoided, or used only under direct professional supervision.
  • Moderate. May need monitoring, a dose adjustment, or separating the times you take each one.
  • Minor. Generally not clinically significant, but still worth noting and mentioning to your pharmacist.
  • No known interaction. Checked against our sources with nothing documented — not the same as proven safety.

Likelihood — How Well It’s Documented

  • Likely. Well-controlled human studies have demonstrated the likely existence of this interaction
  • Probable. Interaction has not been documented in well-controlled studies, however, the interaction has been demonstrated in some small human studies or in controlled animal studies in conjunction with multiple case reports.
  • Possible. 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
  • Unlikely. Interaction has been demonstrated in animal or in lab research but has been shown not to occur in humans.

Ozone Therapy: Uses, Safety & Side Effects

The bottom line

Ozone therapy uses a reactive form of oxygen for a wide range of unproven health claims, and it is not a dietary supplement or herb. High-quality evidence for most uses is limited, and breathing ozone is harmful to the lungs. If you are considering it, talk to a licensed doctor or pharmacist first, since safety and benefit are not well established.

Part used
Medical ozone gas (a mixture of oxygen and ozone)
Common forms
Gas insufflation, ozonated water, ozonated oils, major and minor autohemotherapy (blood treatment), injections
People commonly use it for
  • Wound and skin infections
  • Joint and back pain
  • Immune support
  • Dental and gum care
  • Chronic infections
  • General 'detox' and wellness claims

Popular and traditional uses — not proof it works. See “Uses & effectiveness” below for the evidence.

Overview

Ozone therapy is not an herb or a plant-based supplement. It uses ozone, a gas made of three oxygen atoms (O₃). The same gas that forms part of the Earth's upper atmosphere can be created with a special medical device that passes oxygen through an electrical charge.

People and clinics use ozone therapy in many different ways. These include applying ozonated oils or water to the skin, blowing the gas into body openings (insufflation), injecting it, or removing a small amount of blood, mixing it with ozone, and returning it to the body (called autohemotherapy).

It is promoted for a wide range of conditions, from infections and wounds to pain and general wellness. It is important to know that ozone therapy is not approved by the U.S. FDA as a treatment for any medical condition, and the FDA has warned that ozone is a toxic gas with no known useful medical application in a general sense.

How it works

Ozone is a highly reactive form of oxygen. When it contacts tissues or fluids, it quickly reacts and forms other compounds, including reactive oxygen species and certain fat-related byproducts.

Supporters believe that these reactions may, in small controlled amounts, stimulate the body's own antioxidant defenses, affect immune signaling, and improve how oxygen is delivered or used by cells. Ozone is also known to kill microbes on contact, which is why it is used to disinfect water and surfaces.

It is important to understand that most of these proposed mechanisms come from laboratory and animal research. The same reactivity that may have effects can also damage healthy cells, especially in the lungs. How these effects translate to real benefits in people is still not well understood.

Also studied for 21 conditions — evidence insufficient to rate
Insufficient Reliable Evidence To Rate Back pain
Rating & evidence shown verbatim from Natural Medicines

Research has evaluated ozone therapy injections for back pain caused by a herniated disc. Most observational research has found that injecting ozone into a herniated disc is associated with reduced back pain. Preliminary clinical research and an analysis of preliminary clinical research also show that injecting 5-20 mL of ozone 20-30 mcg/mL into the herniated disc or injecting it into paravertebral muscles seems to improve back pain when compared with baseline or active control. Other preliminary clinical research shows that injecting ozone into the herniated disc is as effective as microdiscectomy for reducing back pain. Additionally, one small clinical study suggests that ozone therapy is most effective in males, patients with isolated radicular pain, patients with calcified disc herniation, and/or patients with symptoms lasting less than one year.

Insufficient Reliable Evidence To Rate Carpal tunnel syndrome
Rating & evidence shown verbatim from Natural Medicines

A small clinical study in patients with mild or moderate carpal tunnel syndrome shows that receiving a single local intraarticular ozone injection in addition to wearing a resting volar wrist splint for 8 weeks results in greater pain reduction (64%) when compared with only wearing the wrist splint (45%).

Sources Ref 102983
Insufficient Reliable Evidence To Rate Coronavirus disease 2019 (COVID-19)
Rating & evidence shown verbatim from Natural Medicines

Research on the use of ozone therapy, including nebulized ozone and ozone autohemotherapy, for the treatment of COVID-19 has yielded mixed findings. It is also unclear if ozone autohemotherapy is beneficial for long-term symptoms occurring after recovery from COVID-19.

Insufficient Reliable Evidence To Rate Dental caries
Rating & evidence shown verbatim from Natural Medicines

A small meta-analysis shows that ozone therapy has inconsistent antimicrobial effects when compared with chlorhexidine and sealants for the treatment of dental caries. The studies in this analysis were limited by risk of bias and imprecision of data.

Sources Ref 106465
Insufficient Reliable Evidence To Rate Diabetes
Rating & evidence shown verbatim from Natural Medicines

Preliminary clinical research shows that ozone therapy administered locally or through rectal insufflations of ozone gas improves blood glucose and markers of oxidative stress. A clinical study in adults with type 2 diabetes shows that receiving a topical oral ozone gas regimen along with conventional periodontal treatment every 3 months does not improve glycated hemoglobin (HbA1c) levels at 12 months when compared with conventional periodontal treatment alone. The validity of these findings is limited by the unblinded nature of the study.

Insufficient Reliable Evidence To Rate Diabetic foot ulcers
Rating & evidence shown verbatim from Natural Medicines

Topical non-invasive ozone therapy has been evaluated for use in the treatment of diabetic foot ulcers with mixed findings. Invasive ozone therapy combined with topical ozone therapy has shown some benefit.

Insufficient Reliable Evidence To Rate Fibromyalgia
Rating & evidence shown verbatim from Natural Medicines

Observational research in patients with fibromyalgia has found that receiving ozone therapy mostly via autohemotherapy and some by ozone rectal insufflations is associated with improved symptoms in 70% of patients when compared with baseline. The validity of this finding is limited by the lack of a comparator group.

Sources Ref 102997
Insufficient Reliable Evidence To Rate Gingivitis
Rating & evidence shown verbatim from Natural Medicines

A small clinical study in adults with plaque-induced gingivitis shows that combining gaseous ozone therapy with periodontal treatment is less effective for reducing gingival inflammation than periodontal treatment alone. Effects were similar between smokers and non-smokers. Similarly, a meta-analysis shows that adjuvant use of ozone therapy with nonsurgical periodontal treatment is no more effective for improving clinical attachment loss, periodontal parameters, or bacterial counts when compared with nonsurgical periodontal treatment alone or in combination with chlorhexidine. The validity of these findings is limited by the high heterogeneity of the included studies.

Insufficient Reliable Evidence To Rate Hearing loss
Rating & evidence shown verbatim from Natural Medicines

Preliminary clinical research shows that ozone therapy via autohemotherapy where 100 mL of a patient's blood is mixed with a 1:1 gaseous mixture of oxygen and ozone and reinjected via intravenous (IV) infusion twice weekly for 5 weeks might improve hearing loss compared to placebo in patients with sudden sensorineural hearing loss. This study is limited by incomplete reporting of results and flawed methodology.

Sources Ref 88743
Insufficient Reliable Evidence To Rate Herniated disc
Rating & evidence shown verbatim from Natural Medicines

Observational research in patients with persistent radicular pain refractory to conservative management and/or epidural steroid injection found that injecting ozone into the herniated disc is associated with a reduction in herniated disc surface area of about 20% in 75% of cases. Also, a small clinical study shows that injecting ozone into the herniated disc is as effective as microdiscectomy for reducing radicular leg pain and disability and improving overall health and mobility.

Insufficient Reliable Evidence To Rate HIV/AIDS
Rating & evidence shown verbatim from Natural Medicines

Preliminary clinical research shows that giving ozone via autohemotherapy three times weekly for 8 weeks does not improve immune response in patients with HIV.

Sources Ref 88745
Insufficient Reliable Evidence To Rate Intermittent claudication
Rating & evidence shown verbatim from Natural Medicines

Preliminary clinical research shows that receiving intravenous ozone therapy 60 mcg/mL in 500 mL of normal saline along with 30-minute aerosol oxygen-ozone baths to the lower legs daily for 10 days seems to improve walking distance compared to balneotherapy in patients with intermittent claudication.

Sources Ref 88738
Insufficient Reliable Evidence To Rate Meniere disease
Rating & evidence shown verbatim from Natural Medicines

Preliminary clinical research shows that inhaled ozone 8 mcg/mL therapy at 60 mL/minute for 10 minutes plus tympanic membrane pressure massage for 10 minutes daily for 10 days does not improve hearing loss compared to baseline in patients with Meniere's disease.

Sources Ref 88749
Insufficient Reliable Evidence To Rate Osteoarthritis
Rating & evidence shown verbatim from Natural Medicines

Meta-analyses of small, low-quality clinical studies in patients with knee osteoarthritis show that intra-articular ozone therapy improves pain for up to 6 months when compared with placebo. However, ozone therapy seems to be less effective than hyaluronic acid or platelet-rich plasma. The validity of these analyses is limited by a high risk of bias and short duration of the included studies.

Insufficient Reliable Evidence To Rate Periodontitis
Rating & evidence shown verbatim from Natural Medicines

Topical ozone therapy has been evaluated for use in the treatment of periodontitis with mixed findings. Two small clinical studies in patients with chronic periodontitis show that applying ozone as ozonated olive oil to gum pockets is as effective as chlorhexidine 0.2% or 1% for improving most periodontal measures. In one study, ozonated olive oil was applied once immediately after scaling and root planing and then once more one week thereafter. In the other, ozonated olive oil gel (Bioemmei Srl) was applied two weeks after professional oral hygiene. However, in one of these studies the improvements in clinical attachment and gingivitis indices were similar to chlorhexidine 1% at 1 month, but not at 3 months. Also, a small clinical study in patients with severe generalized periodontitis shows that applying gaseous ozone into periodontal pockets twice weekly for 2 weeks does not improve periodontal parameters when compared with baseline. This study was limited due to a lack of comparator group.

Insufficient Reliable Evidence To Rate Postherpetic neuralgia
Rating & evidence shown verbatim from Natural Medicines

A preliminary clinical study in patients with postherpetic neuralgia shows that receiving ozone 40 mL via autohemotherapy three times weekly for 2 weeks addition to pharmacotherapy seems to improve pain at 1 month and 3 months when compared with pharmacotherapy alone.

Sources Ref 102990
Insufficient Reliable Evidence To Rate Postoperative pain
Rating & evidence shown verbatim from Natural Medicines

A meta-analysis of small clinical trials in patients undergoing surgery for an impacted mandibular third molar shows that adjuvant ozone application modestly reduces pain and analgesic use for up to 7 days after surgery, but does not affect swelling or jaw movement restriction, when compared with no ozone treatment. In one of the studies included in the analysis, a specific ozone product (Ozone gel, Aqua Ozone) was applied to the tooth socket for 2 minutes twice daily for 3 days in addition to using analgesics. Other modes of application evaluated in the meta-analysis include the use of an extraoral ozone probe and ozonated water irrigation.

Insufficient Reliable Evidence To Rate Rheumatoid arthritis (RA)
Rating & evidence shown verbatim from Natural Medicines

Preliminary clinical research in patients with RA shows that adding ozone therapy as 25 mg/L to 40 mg/L via rectal insufflation for 5 days weekly for 4 weeks to methotrexate therapy seems to improve disease activity measures and pain when compared with methotrexate alone.

Sources Ref 98148
Insufficient Reliable Evidence To Rate Scleroderma
Rating & evidence shown verbatim from Natural Medicines

A small preliminary clinical trial in patients with digital ulcers related to systemic scleroderma shows that local ozone treatment modestly improves digital ulcer severity and hand function when compared with standard treatment alone. The hand was exposed to oxygen-ozone in a bag for 30 minutes daily for one week, followed by twice weekly for the next 3 weeks. Another small clinical study shows that exposing the digits to oxygen-ozone for 30 minutes daily for 20 days results in the healing of digital ulcers in 96% of participants, compared with 44% of those given standard treatment with calcium channel blockers alone. Digits were exposed to a total volume of 20-50 mL of ozone at 52 mcg/mL in a bag using an ozone generator device (Humazon Promedic). Exposure to ozone also reduced ulcer pain and the number and duration of Raynaud attacks.

Insufficient Reliable Evidence To Rate Temporomandibular disorders (TMD)
Rating & evidence shown verbatim from Natural Medicines

Limited research suggests that applying ozone topically may reduce pain in patients with TMD, but it does not appear to improve jaw mobility. Preliminary clinical research in patients with masticatory myofascial pain due to TMJ dysfunction shows that applying topical ozone therapy at 60% intensity to the site of greatest pain for 10 minutes three times per week for 2 weeks modestly reduces pain but does not improve jaw movement when compared with sham ozone therapy. Ozone therapy has also been compared to active controls such as medication and occlusal splints. A small clinical study shows that applying topical ozone therapy at 30% intensity for 10 minutes three times per week for one week improves pain to a greater degree when compared with taking ketoprofen 150 mg and thiocolchicoside 8 mg twice daily for 7 days; however, mouth opening is not improved. Another small clinical study in patients with TMD shows that receiving 60% ozone exposure to pain points for 10 minutes three times weekly for two weeks reduces pain to a similar degree as wearing an occlusal splint every night for four weeks. This study was limited due to small sample size and differences in treatment duration.

Insufficient Reliable Evidence To Rate Tinnitus
Rating & evidence shown verbatim from Natural Medicines

Preliminary clinical research shows that applying ozone autohemotherapy, where 100 mL of a patient's blood is mixed with a 1:1 gaseous mixture of oxygen and ozone, does not improve tinnitus compared to baseline and compared to a betahistidine control in patients with idiopathic tinnitus for at least 6 months.

Safety & precautions

The biggest safety concern is that ozone gas is harmful to breathe. Inhaling it can irritate and damage the lungs and airways, cause coughing, chest pain, and shortness of breath, and may worsen asthma or other lung conditions. Ozone should never be inhaled.

Injecting ozone, or certain procedures done improperly, can lead to serious problems such as air or gas bubbles in the bloodstream (gas embolism), infections, and other complications. Because of this, any ozone procedure should only be done by a qualified, licensed healthcare provider using sterile technique.

People with bleeding disorders, certain enzyme deficiencies (such as G6PD deficiency), heart or lung disease, or weakened immune systems should be especially cautious and speak with a doctor first.

Pregnancy and breastfeeding: There is not enough reliable safety information, so ozone therapy should be avoided during pregnancy and while breastfeeding.

Side effects

Side effects depend on how ozone is used. Reported effects include:

  • Burning, irritation, or discomfort at the site of application or injection
  • Coughing, chest tightness, and breathing problems if the gas is inhaled
  • Headache, fatigue, or feeling unwell after treatment
  • Cramping or discomfort with rectal or other insufflation methods

Rare but serious problems can include gas embolism (gas bubbles in the blood), infections, and reactions in people with red blood cell enzyme disorders. Seek emergency care for sudden chest pain, severe shortness of breath, fainting, or signs of a serious reaction.

Ozone Therapy: Reported Adverse Effects

Documented safety reports on Ozone Therapy from the evidence-graded Natural Medicines (TRC Healthcare) database, shown word-for-word from the licensed record.

Ozone therapy, applied locally or rectally, has not been linked to serious adverse effects; however, a thorough evaluation of safety outcomes with these routes of administration has not been conducted.

Inhaled ozone therapy and ozone therapy injected into a herniated disc have been linked to cases of Anton syndrome, involving blindness secondary to ischemic stroke or secondary to encephalopathy, and also cases of heart attack, pulmonary embolism, and death. Intravenously, ozone infusion has been linked to pulmonary embolism and death.

Reports by condition
Cardiac arrest Cardiovascular

Inhaled ozone therapy and ozone therapy injected into a herniated disc have been associated with cases of Anton syndrome. Anton syndrome involves blindness secondary to ischemic stroke. The patient is typically unaware of the blindness due to cerebral damage. Intravenously, ozone infusion has been linked to pulmonary embolism and death. Ozone injected into the spine has been linked with cases of heart attack, pulmonary embolism, and death. In a case report, an 80-year-old female developed pulmonary embolism resulting in death after receiving two ozone injections into the spine near a herniated disc. In another case-report, a 66-year-old female developed a spinal cord infarction and ST-elevation myocardial infarction (STEMI) after receiving an ozone injection for disc herniation.

Cluster headache Neurologic/CNS

Inhaled and injected ozone has been associated with blindness and encephalopathy. In a case report, a 36-year-old female presented with Anton syndrome, or ischemic stroke resulting in sudden bilateral blindness, nausea, vomiting and loss of strength after using inhalation ozone therapy for 1 week intended to help with hearing loss and tinnitus from Meniere disease. Reversal of blindness was not reported. In another case report, a 54-year-old male developed Anton syndrome and blindness after an ozone injection for disc herniation. The blindness was followed by severe frontal headache, vomiting, and nausea. In a case report, a healthy 66-year-old male presented to the emergency room with encephalopathy, fever, severe vision loss in both eyes, memory impairment, nausea, and vomiting after receiving an intramuscular paravertebral cervical injection of 20 mL containing ozone and lidocaine 2%.

Dosing

There is no standardized, proven dose for ozone therapy, and it varies widely between providers and methods. Concentrations, volumes, and treatment schedules are not well established by high-quality research.

Because ozone is reactive and potentially harmful, you should never try to make or use it at home. If you are considering ozone therapy, only do so under the supervision of a licensed, experienced healthcare professional, and discuss it with your own doctor or pharmacist first to make sure it is appropriate and safe for you.

Ozone Therapy: Common Questions

What is Ozone Therapy used for, and does it work?
People use Ozone Therapy for a range of reasons, but according to the Natural Medicines database the current clinical evidence is insufficient to confirm it works for the specific conditions it has been studied for. See the graded list on this page, and talk to your pharmacist or doctor before relying on it for any condition.
Does Ozone Therapy interact with prescription medications?
We do not currently list any known drug interactions for Ozone Therapy. This does not guarantee that none exist, so always confirm with your pharmacist before combining it with your medications.
How are Ozone Therapy interactions rated?
Each interaction is graded major, moderate, or minor based on how clinically significant it is and the strength of the evidence behind it. Major interactions are the most serious and are best avoided, or used only under close professional supervision.
Is it safe to take Ozone Therapy with my medications?
It depends on the specific medication. Some combinations are fine, while others call for monitoring, timing changes, or should be avoided. Check your exact drug above and confirm with your pharmacist or doctor before starting, stopping, or changing anything.
Where does this Ozone Therapy interaction information come from?
Our interaction data is built on the Natural Medicines database — an evidence-graded reference for vitamins, herbs, and supplements — and is reviewed by licensed HelloPharmacist pharmacists, who may add clinical context.
What is Ozone Therapy used for?
People use it for things like wounds, infections, joint and back pain, dental problems, and general 'wellness.' For most of these uses, strong scientific proof of benefit is lacking.
Is Ozone Therapy safe?
It can be risky. Ozone gas is toxic to the lungs if inhaled, and some procedures carry serious risks like infection or gas bubbles in the blood, so it should only be done by a qualified professional.
Is Ozone Therapy approved by the FDA?
No. The FDA has not approved ozone for any general medical use and has stated that ozone is a toxic gas, so treat any health claims with caution.
Can I use Ozone Therapy while pregnant or breastfeeding?
It is best to avoid it, because there is not enough reliable safety information for pregnancy or breastfeeding. Talk to your doctor first.
