Transdermal Patches: Risk of Burns During MRI - March 2009

The U.S. Food and Drug Administration (FDA) has issued a public health advisory regarding the risk of burns associated with the use of transdermal medication patches containing aluminum or other metals during MRI screening. The package labeling for certain metal-containing patches includes a warning related to the risk of burns if the patches are not removed prior to MRI procedures. However, not all transdermal medication patches with metallic backings have this warning in the labeling. Although metal materials are present in certain patches, it may not be visible. The FDA is currently reviewing the components of all transdermal medication systems to ensure that proper warnings are present in the labeling of those patches that do contain metal materials. In the interim, the FDA recommends that healthcare professionals who refer patients to have an MRI procedure should identify patients who are wearing a transdermal medication patch prior to the scan. Those patients who are wearing a transdermal medication patch should be advised on the proper removal of the patch prior to the procedure as well as reapplication following the scan.
