What the authors reported

Discussing published case reports of adverse reactions attributed to ozone therapy, by technique of administration, the authors state that most safety issues are secondary to infections or traumatic reactions due to malpractice, and that the ozone molecule itself is commonly not responsible for severe reactions under the therapeutic modalities.

What limits this result

Narrative review, read from the abstract only. The abstract states no search method, number of reports reviewed, or event counts, and gives no counted figures for its statement that the millions of patients treated worldwide over 40 years demonstrate the therapy's safety.

Harms reported after ozone therapy, and studies of how ozone exposure affects health. One study rarely settles a medical question; our guides weigh each paper against the rest of the evidence.

What it measured

Focus of the review
Reported adverse reactions, discussed mainly by technique of administration rather than the contact of ozone with biological material
Cause of most safety issues in the published case reports
Secondary to infections or traumatic reactions due to malpracticeThe case reports on OT treatments safety concerns discussed on international journals, make it possible to state that most safety issues are secondary to infections or traumatic reactions due to malpractice.
Role of the ozone molecule
Commonly not responsible for severe reactions at the therapeutic modalities
Authors' conclusion on safety
The patients treated by physicians practicing ozone therapy worldwide over the last 40 years demonstrate its safetyThe millions of patients treated so far from the thousands of physicians correctly practicing OT world widely in the last 40 years demonstrate the safety of this simple and cost-effective regenerative medicine tool.
