FDA has ruled that LLLT (Low Level Laser Therapy) is safe and the only contraindication (warning) is not to use it directly in the eyes.
For the past 30 years the technology of Low Level Laser Therapy (LLLT) has been formally accepted in many parts of the world such as Canada, USA, Brazil, Europe, Scandinavia, Russia and Japan. In all this time there have been no recorded long-term adverse effects from its use. It is considered to be non-invasive, painless and safe.
Laser Therapy is non-invasive, non-toxic and non-thermal. Unlike other forms of radiation, Laser Therapy is beneficial rather than harmful to tissue. LLLT also improves healing and reduces muscle fatigue, muscle damage and delayed onset muscle soreness.
There are normally no adverse effects from LLLT, however, patients occasionally experience mild discomfort/ache after treatment. This is due to a restimulation of the inflammatory phase and should settle down after 24 – 48 hours.
