I had a CT with oral IV contrast today at noon and took Barium Sulfate. I didn t notice a strong metallic taste, but I did have a slight metallic taste in my mouth and still do, slightly. Also, I ve since gotten a fever of 99.5 and have had diarrhea and nausea. However, I had the CT to test for gastrointestinal issues (particularly possible diverticulitis or IBS). I have had an ongoing low grade fever, ranging from 98.9-99.9 but have not had one in over a week and a half. Should I be concerned about this possible reaction to the barium contrast?
