FDA advisory: Magnets in cell phones, smart watches can affect implanted medical devices
Magnets in cell phones and smart watches may have a temporary effect on pacemakers and other implanted medical devices, according to a new FDA advisory. Though this does not seem to be a significant issue, the agency still recommends keeping consumer electronics at least six inches away from implanted medical devices just to be safe.
Many implanted devices were designed with a “magnet mode” that make MRI scans and other medical procedures safer for the patient. It typically takes a high-field magnet to engage this setting—and the device goes back to normal as soon as the magnetic field is removed—and this built-in feature appears to be what is causing the temporary disruptions.
“We believe the risk to patients is low and the agency is not aware of any adverse events associated with this issue at this time,” Jeff Shuren, MD, JD, director of the FDA’s Center for Devices and Radiological Health, said in a statement. “However, the number of consumer electronics with strong magnets is expected to increase over time. Therefore, we recommend people with implanted medical devices talk with their health care provider to ensure they understand this potential risk and the proper techniques for safe use.”
The FDA noted that it will continue to monitor this issue and “take appropriate action … if the need arises.”
