Safety & contraindications
No side effects reported across trials — with a few clear exclusions.
The safety profile
No side effects have been reported with tPEMF across clinical trials to date. Unlike narcotics — which carry nausea, sedation, and addiction risk — tPEMF works with the body's own processes and has no overdose pathway.
Do not use with
Implanted leads or lead-containing electronic implants — pacemakers, defibrillators, cochlear implants, bone-growth stimulators — even if turned off. As a precaution: during pregnancy, and over the joints/growth plates of skeletally immature patients.
Why the physics guarantee the safety profile
Non-thermal: at 4 microtesla amplitude, the field cannot raise tissue temperature — the energy density is simply too low. Non-ionizing: at 27.12 MHz, the photon energy is approximately 10⁻⁷ electron volts — roughly 10 billion times below the ionizing threshold. No current enters the body: the mechanism is inductive field coupling to intracellular signaling, not transcutaneous electrical stimulation. There is no chemical deposition, no radiation dose, and no cumulative exposure risk. The biological target — the calmodulin-NO pathway — is a normal, constitutive physiological process. The device does not push this pathway beyond its normal operating range; it accelerates it.
Compared to the alternative
Opioids: nausea in 25–40% of patients, respiratory depression risk, dependence risk increasing with cumulative dose, constipation prolonging hospital stays. NSAIDs: GI ulceration risk, platelet inhibition (bleeding risk in fresh wounds), renal function concerns with prolonged use, cardiovascular risk with COX-2 selective agents. Cortisone injections: structural damage concerns with repeat dosing, glycemic effects in diabetic patients, infection risk, skin depigmentation at injection site. tPEMF: no reported adverse effects across clinical trials. The comparison is not a close call from a safety standpoint.
