TY - JOUR T1 - Fda warning: Remove drug patches before mri to prevent burns to skin AU - Kuehn BM Y1 - 2009/04/01 N1 - 10.1001/jama.2009.406 JO - JAMA SP - 1328 EP - 1328 VL - 301 IS - 13 N2 - The nonadhesive backing of some drug patches contains aluminum or other metals that may become heated during an MRI. Many labels for such products already warn of such a risk; however, the FDA was recently alerted that Teva Pharmaceutical's fentanyl transdermal system lacked this warning. Further investigation by the agency revealed that a warning is also missing from the labels of a variety of other medicated patches.
