On Tuesday, I will be having my annual follow-up CT scan for lung cancer. My oncologist has ordered it with contrast, which certainly gives a better picture of what is going on. However, a) I have had an allergic reaction to the contrast in the past (hives). The doctor has prescribed desamethasone (a steroid) for 8 hours and 4 hours before the infusion, and diphenhydramine HCl (Benedryl) 1 hour before. That should take care of the allergic reaction.
But b) I have heard that large amounts of iodine can interfere with treatment for hypothyroidism. Is there anything I can do to flush out the iodine from my system afterwards?
