The FDA has issued a public health advisory warning people of the potential of transdermic drug patches to heat up. Because many varieties contain thin metallic strips within the patch, people are basically advised to not forget to take them off before the exam.
Here’s from the notice:
FDA recommends that healthcare professionals referring patients to have an MRI scan identify those patients who are wearing a patch before the patients have the MRI scan. The healthcare professional should advise these patients about the procedures for removing and disposing of the patch before the MRI scan, and replacing the patch after the MRI scan. MRI facilities should follow published safe practice recommendations concerning patients who are wearing patches.
FDA recommends that patients who use medicated patches (including nicotine patches) do the following:
* Tell the doctor referring you for an MRI scan that you are using a patch and why you are using it (such as, for pain, smoking cessation, hormones)
* Ask your doctor for guidance about removing and disposing of the patch before having an MRI scan and replacing it after the procedure.
* Tell the MRI facility that you are using a patch. You should do this when making your appointment and during the health history questions you are asked when you arrive for your appointment.
