    metformin and iodine interaction

    sensen22 posted:
    I had a CT scan which required an injection of iodine. The tec told me to stop taking my metformin for a couple of day or at least until I had a blood test to determine if any damage had been done to my liver. Anyone know any thing about this matter, or where I can find information about the possible interactions of there drugs?

    The contrast agent used in some CT scans contains iodine. It is filtered by the kidneys. Usually the doctor will order a comprehensive metabolic panel (CMP) to assess kidney function prior to the scan.

    Also, it is customary to discontinue the Metformin the day of the scan and for a few days after the scan.

    That was my experience. Here is a link with more information:
