Diarrhea For 2 Months Following Two Petct Scans Each Time Has Anyone Else Experienced This

It can't be a coincidence that I had, and am now having again, diarrhea following each of the last 2 PET CT scans that I have had for melanoma in a lymph node. I have looked up the active ingredient in the CT part, Omnipaque 350, and see that is one study, 42% of 54 people had diarrhea, but it doesn't say how long it lasted. It went away for 3 months in between the scans. Please let me know if you have experienced this. Thanks

It has been known to cause what's described as 'various GI disturbances', so diarrhea really isn't too surprising.

Learn more Omnipaque details here.

I don't remember what contrast agent was used when I has one done, but I did have diarrhea for awhile afterwards, as well. I was able to take some over the counter Imodium to clear it up.

Can you take Imodium/Loperamide?

If so, then you may want to look into it.
