Could ozone therapy ease fibromyalgia pain and fatigue?
NCT ID NCT07680621
First seen Jul 02, 2026 · Last updated Jul 02, 2026
Summary
This study investigates whether major ozone autohemotherapy — a procedure where a small amount of blood is mixed with ozone and returned to the body — can improve pain, fatigue, sleep, and muscle health in women with fibromyalgia. Sixty participants will receive either exercise alone or exercise plus ozone therapy twice a week for five weeks. Researchers will measure changes in symptoms and muscle function over three months to see if the treatment offers lasting benefits.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- ozone gas
- What this could lead to
- If it works, this could offer a new option to reduce pain, fatigue, and sleep problems in people with fibromyalgia.
- What could go wrong
- This is a small, early-stage study with only 60 participants. Ozone therapy may not prove effective, and its long-term safety is not yet established.
