Is Photobiomodulation Therapy Safe? Risks, Side Effects & Research

When it comes to medical treatments, safety is always the first concern—and rightfully so. If you’re considering adding photobiomodulation therapy (PBMT) to your treatment plans for pain relief , you might be wondering: Is this therapy safe?

The short answer is yes. PBMT is a safe, non-invasive treatment that has been used for decades. There are several devices that deliver PBMT that are  FDA-cleared for pain relief, and there are few known side effects.

Here’s What You Really Need to Know

Photobiomodulation therapy is safe, non-invasive, and drug-free. LightForce® Laser Therapy uses specific wavelengths of near-infrared light to stimulate the body at the cellular level. PBMT is backed by numerous clinical studies.

What Makes PBMT Safe?

Unlike medications or surgery, PBMT:

• Does not break the skin
• Does not involve chemicals
• Does not require down time

What the FDA and Clinical Research Say

Photobiomodulation therapy is:

• Indicated for temporary relief of minor muscle and joint pain and stiffness, minor arthritis pain, or muscle spasm, the temporary increase in local blood circulation, and the temporary relaxation of muscle.
• Endorsed by clinical bodies such as WALT (World Association for Photobiomodulation Therapy)
• Backed by a substantial body of peer-reviewed research

PBMT has been used in:

• Physical therapy
• Chiropractic
• Sports medicine
• Podiatry
• Orthopedics

And is widely accepted as a safe adjunct or alternative to more invasive interventions.

Possible Side Effects of PBMT

In some cases, patients may experience mild, short-term effects, such as:

• Redness or skin irritation
• Temporary increase in symptoms
• Skin warmth or tingling in the treated area
• Soreness or discomfort

Who Should Be Cautious?

While PBMT is safe for most people, certain precautions apply:

• Pregnant individuals – Avoid direct treatment over the abdomen and lower back
• Patients with cancer – Avoid treating around tumors
• Patients with pacemakers – Avoid treating over the pacemaker or in the chest area
• Photosensitive or heat sensitive medication users – Inform your provider before treatment
• Children – avoid treating near or directly over growth plates

Providers who purchase a LightForce® therapy laser receive training to identify these contraindications and adjust protocols accordingly.
