Redness of the skin in contact with the magnet has been reported, but most cases self-resolve within 24 hours of removal of the device. Patients who use cardiac pacemakers, implanted automatic defibrillators, or insulin pumps should not use magnet therapy without consulting their health-care provider.

Some manufacturers warn that magnets can interfere with the pharmacokinetics of transdermal medications, such as pain patches. Although this theory has not been proven, it warrants consideration. 

Cost, How Supplied

The cost of magnet therapy is highly variable. Generally, the cost of the device rises with the quality and strength and varies from as low as $10 to as much as $100 or more. Patients should thoroughly research any product before buying.


Magnet therapy is still on the outer fringe of any sort of evidence-based practice. However, even the studies that did not show benefit failed to show any negative safety issues. Consequently, health-care professionals should be aware of the emerging data and help their patients make informed decisions regarding magnet therapy.
