A few weeks ago I was given radio active iodine contrast for a stress test. Because I am allergic to iodine, they gave me 150 mg. prior to the test - all in one day.
How many days would be normal for such a reaction from the vaccine if taking 20 mg. of prednisone?
I understand this is not a treatment site. I do not take issue with that, but would appreciate a general response for a generalized question.
