MEDICATION PATCHES
A patient wearing a transdermal nicotine patch (Habitrol, 21 mg) while undergoing magnetic resonance imaging (MRI) began thrashing around as the third scanning cycle was started. When the technician stopped the test and removed I the patient from the magnet, the patient stated that his arm was burning. His upper left arm was mildly erythematous, and a small, denuded blister appeared where the patch had been.
Some medication patches have an aluminized backing that can heat excessively if placed within the MRI magnetic field and damage the skin. If your patient is about to undergo an MRI, prevent burns by making sure any patch he's wearing is free from metal; remove the patch if you're not sure. Follow the prescribing guidelines for reapplying a patch after the procedure.
