Question: My husband needs catheterization, but he is allergic to the contrast used in the test. They tried to premedicate him with prednisolone but he reacted badly. Can gadolinium or another contrast medium be used? Socorro (Mexico).
Answer: In principle, there is no viable alternative to this contrast for catheterization. Usually with strong premedication it can usually be used. When this option does not work, you can try to desensitize to gradually accustom the body to this contrast medium.
