Hi everyone! I had a CAT scan with IV contrast Friday. When I got home, my food tasted funny (I didn't get a metalltic taste but my urethra burned like crazy with the dye). At first, I thought it might be due to the antibiotic I'm taking for my way out of control UTI, Macrobid. I looked up the side effects and now know why my arms and hands keep getting pins and needles and go numb but no mention of metallic taste. I know it's not the Pyridiium because I've taken it before without a problem. The only other new thing put into my body was that dye. At first, I thought that maybe the company who made the stuff I ate changed the recipe but I then noticed that every food tastes funny, but it's onlly on both sides of my tongue and it's a very tart type of taste. Could it still be the IV contrast dye 24 hours later?

  • This can indeed be related to the contrast material and although the body typically eliminates it within about 24 hours or so, complete removal may be 48 to 72 hours depending upon clearance efficiency that varies between patients. Certain antibiotics, however, also produce a characteristic bitterness in the mouth that resolves upon completion of the prescription duration. You'll be fine. Best regards, J Cottle, MD
